The first tube segment 711 has two outer flat surfaces 7111 formed on the outer surface and abutting against the inner flat surface 2111 of the corresponding first seat tube 211, and two fitting blocks 7112 extending from the end portions in a direction parallel to the axis X. The second tube segment 712 has two outer flat faces 7121 formed on the outer surface and abutting against the inner flat face 2111 of the corresponding first seat tube 211, two concave portions 7122 formed at the opposite ends, and two caulking grooves 7123 extending from the ends in the direction parallel to the axis X and butt-fitted to the fitting block 7112. The brake spring assembly 72 has a plurality of springs 721 disposed between the friction member 73 and the pad 75, and a spacer 722 disposed between the two pads 75. The friction member 73 has two protrusions 731 formed on an outer circumferential surface thereof to be fitted into the recesses 7122, and a friction curved surface 732 formed on one end surface thereof. Thereby, the pipe 71 is interlocked with the abutting relationship between the outer flat surfaces 7111 and 7121 and the inner flat surface 2111 of the corresponding first seat pipe 211. It should be noted that the two-section pipe 71 is also easy to manufacture, easy to control in precision, and can be manufactured by using different materials to meet different requirements by improving the strength of the whole pipe during rotation through concave-convex matching so as to prevent breakage, and the joint portion of the first pipe section 711 and the second pipe section 712 needs to be located in the corresponding first seat pipe 211.
In this embodiment, the mandrel 4 includes a fixing member 41 positioned in the second seat tube 221 of the second sheet 22 and rotating synchronously with the second sheet 22, a shaft section 43 penetrating the kit unit 6, and a shaft section 44. It is noted that the distal acting member 63 is located between the hydraulic cylinder 621 and the shaft section 43. And the proximal acting element 64 is disposed between the shaft segment 43 and the fixed element 41.
The fixing member 41 has a square bolt hole 411 and a recess 412 arranged along the axis X direction, and two grooves 413 formed on two opposite sides along the axis X direction. In this embodiment, the groove 412 is a circular groove.
The shaft segment 43 passes through the through hole 642 and has a stud 431 coupled with the square stud hole 411 of the fixing member 41 to form a linkage, a pressing surface 432 opposite to the stud 431 and for the knock pin 622 and the elastic element 623 to press against, a surrounding wall 433 defining a groove with the pressing surface 432, and a proximal engaging surface 434 opposite to the pressing surface 432 and facing the proximal inclined surface 434. The peripheral wall 433 has a distal engagement face 4331 opposite the proximal engagement face 434 and facing the distal ramp 631. In this embodiment, the studs 431 are square studs.
The shaft section 44 has one bolt hole 440 that is fitted and interlocked with the bolt 431 of the shaft section 43, one bolt 441 that is engaged and interlocked with the groove 413 corresponding to the fixing member 41, and two protrusions 442 facing the frictional curved surface 732 of the kit unit 7. In this embodiment, the key hole 440 is a square key hole. The studs 441 may also be designed to interlock with the recesses 412. The protrusions 442 are in frictional contact with the corresponding frictional curved surfaces 732 of the friction member 73. It should be noted that, by controlling the curvature position of the friction curved surface 732 of the friction member 73, the first leaf 21 interlocked with the kit unit 7 or the second leaf 22 interlocked with the fixing member 41 and the friction member 73 can be controlled to generate a friction stop effect at the highest point of the friction curved surface 732 at a predetermined angle (e.g. 80-90 degrees), so that the door can be temporarily stopped at the predetermined angle position, and the door can be automatically closed only by slightly pulling or pushing the door by hand, or the door closing speed of the door can be controlled to change by generating a friction resistance effect at the friction curved surface 732 at a predetermined angle, for example, less than 20 degrees or 20-60 degrees, when the door is closed by the first leaf 21 or the second leaf 22. It should be noted that, the angle for temporarily stopping the rotation of the door or changing the door closing speed of the door can be arbitrarily changed from 180 degrees to 80 degrees according to the curvature position of the friction curved surface 732 of the friction member 73 and the customer's requirement, but not limited thereto.
Referring to fig. 2 and 8, the ring unit 5 includes two collars 51 and two spacing groups 52. The collar 51 is inserted between the pipe members 61, 71 of the kit units 6, 7 and the second seat pipe 221, respectively. Each spacer group 52 has a spacer ring 521. The spacer ring 521 has a ring wall 522 penetrating the second seat tube 221 and a ring edge 523 blocking the gap between the first seat tube 211 and the second seat tube 221. The collar 51 and the spacer 52 may be made of Polyoxymethylene (POM) or teflon (PTFE) for improving the lubrication between the first seat tube 211, the second seat tube 221 and the tube members 61, 71 of the kit units 6, 7 and reducing the resistance and wear.
When the articles 11 and 12 are connected, the first reference surface 213 of the first sheet 21, the second reference surface 223 of the second sheet 22, or the edge 111 of the article 11, or the edge 121 of the article 12 is only required to abut against, so that the plurality of hinge devices can be aligned in a straight line in the vertical direction and the parallel direction with respect to the article 11 or the article 12, thereby avoiding errors in the positions of the hinge devices in the vertical direction and the parallel direction during the installation, and improving the smoothness during the rotation of the door leaf.
Referring to fig. 1, 5 and 6, when the first blade 21 is driven by an external force to rotate around the axis X to open the door, the first blade 21 drives the pipes 61 and 71 of the kit units 6 and 7 synchronously through the first seat pipe 211. At this time, since the engagement block 632 of the distal acting element 63 is fitted into the first groove 6112 of the first tube 611 and the second groove 6123 of the second tube 612, when the first leaf 21 rotates, the tube 61 simultaneously drives the distal acting element 63 and the proximal acting element 64 to rotate, and when the second seat tube 221 of the second leaf 22 and the fixing element 41 and the shaft section 43 are not rotated, the tube 61, the distal acting element 63 and the proximal acting element 64 are forced to abut against the proximal engagement surface 434 of the shaft section 43 by the proximal inclined surface 641 to enlarge the distance between the shaft section 43 and the proximal acting element 64, and the shaft section 43 is pushed to move linearly up and down in the direction of the distal acting element 63, and the distal inclined surface 631 engages with the distal engagement surface 4331, the distance between the shaft section 43 and the distal end effector 63 is reduced, so that the shaft section 43 pushes the top pin 622 to press the valve needle 6213 of the hydraulic cylinder 621 to extend and contract to control the door closing speed, and the pressing surface 432 compresses the elastic element 623 to generate the mutually linked acting force.
Meanwhile, the pipe member 71 will synchronously drive the friction member 73 to rotate, and also under the condition that the second seat pipe 221 of the second sheet 22 and the fixing member 41 are not rotated, the friction member 73 and the convex portion 442 of the shaft section 44 are in frictional contact during the rotation process, so as to generate the trigger force resisting the aforementioned external force.
When the external force is released, the elastic element 623 is pressed by the hydraulic cylinder 621 and the distal acting element 63 when the door is closed, and when the door is closed, an elastic restoring force is provided, so that the tube 61 of the kit unit 6, the distal acting element 63, the proximal acting element 64, the tube 71 of the kit unit 7, the friction element 73 and the first leaf 21 rotate in opposite directions, until the distal acting element 63 pushes the distal engagement surface 4331 of the shaft segment 43 by the distal inclined surface 631, so as to enlarge the distance between the distal acting element 63 and the shaft segment 43, the proximal acting element 64 engages the proximal engagement surface 434 of the shaft segment 43 by the proximal inclined surface 641, and when the distance between the proximal acting element 64 and the shaft segment 43 is reduced, so as to displace the shaft segment 43 toward the proximal acting element 64, and the ejector pin 6213 of the hydraulic cylinder 621 no longer presses the ejector pin 622, thereby releasing the compression force of the elastic element 623 and the thimble 6213 of the oil hydraulic cylinder 621.
It should be noted that even if the triggering force of the elastic element 623 is insufficient, during the forward and reverse rotation of the inclined surface 631 of the distal acting element 63, the distance between the distal acting element 63 and the shaft segment 43 can be enlarged and the distance between the proximal inclined surface 641 of the proximal acting element 64 and the proximal engagement surface 434 of the shaft segment 43 can be reduced by pushing the distal inclined surface 631 of the distal acting element 63 through the engagement relationship with the distal engagement surface 4331 of the shaft segment 43 to assist the forward and reverse rotation of the distal acting element 63.
Since the hinge device of the present invention has no directional limitation when being installed, when the second leaf 22 is driven by external force to rotate around the axis X to open the door, the second leaf 22 synchronously drives the fixing member 41 of the spindle 4 through the second seat tube 221, so that the fixing member 41 synchronously rotates the shaft section 43 and the shaft section 44 through the engaging relationship between the square bolt hole 411 of the fixing member 41 and the bolt 431 of the shaft section 43, the engaging relationship between the groove 413 and the bolt 441 of the shaft section 44, and the engaging relationship between the bolt 431 of the shaft section 43 and the bolt hole 440 of the shaft section 44.
Thereby, the convex portion 442 of the shaft segment 44 is brought into frictional contact with the friction member 73, a trigger force against the external force is generated, and the door closing speed is controlled by the magnitude of the trigger force.
At the same time, the proximal engagement surface 434 of the shaft section 43 is forced to abut against the proximal inclined surface 641 of the proximal acting element 64, and since the proximal acting element 64 is fixed in the groove 6122 of the second tube section 612 of the tube 61, the distance between the shaft section 43 and the proximal acting element 64 is expanded, the shaft section 43 is pushed to move linearly up and down toward the distal acting element 63, the distance between the shaft section 43 and the distal acting element 63 is reduced by engaging the distal inclined surface 631 with the distal engagement surface 4331, the shaft section 43 is pushed to press the ejector pin 6213 of the hydraulic cylinder 621 by the ejector pin 622, and the elastic element 623 is compressed by the pressing surface 432 to reduce the distance, so that the ejector pin 6213 of the hydraulic cylinder 621 is inwardly compressed to generate resistance (i.e. trigger force).
Whereby, when the external force is released to close the door, the second leaf 22, the shaft section 43 and the shaft section 44 are driven by the return elastic force of the elastic element 623 to rotate in opposite directions, so that the shaft section 43 pushes the distal inclined surface 631 of the distal acting member 63 against the distal engaging surface 4331 during rotation without rotating the tube 61, the distal acting member 63, the proximal acting member 64, the tube 71 of the kit unit 7, the friction member 73 and the first leaf 21 of the kit unit 6, and the distance between the distal acting member 63 and the shaft section 43 is enlarged by the return elastic force of the spring 623, and the distance between the proximal acting member 64 and the shaft section 43 is reduced by engaging the proximal engaging surface 434 with the proximal acting member 64, and at the same time, the shaft section 64 is displaced toward the proximal acting member 64 and does not press against the top pin 622, thereby releasing the compression force of the elastic element 623 and the thimble 6213 of the oil hydraulic cylinder 621.
It should be noted that the hexagonal setting hole 6211 of the hydraulic cylinder 621 can be inserted by a hand tool, so that the screwing depth of the hydraulic cylinder 621 and the pipe 61 can be adjusted by rotating the hydraulic cylinder 621 by the hand tool, and the tightness at the contact position of the thimble 6213 of the hydraulic cylinder 621 and the thimble 622 is adjusted to move the position of the buffer area, thereby adjusting the angle range with the hydraulic buffer area for door closing deceleration. The hexagonal orifice 6212 may be inserted into another hand tool, so that the flow rate of the oil pressure inside the oil pressure cylinder 621 is adjusted by the hand tool to control the door closing speed, and in addition, the end piece 74 may be screwed in or out, and the trigger force of the spring 721 is changed by the pad 722, or the friction piece 73 with different friction curved surfaces 732 is replaced, so that the friction curved surface 732 of the friction piece 73 and the protruding part 442 of the shaft section 44 may generate friction resistance at different angles, and the magnitude of the friction force may be adjusted to form another way of mechanically controlling the door closing speed. Therefore, the door closing speed is controlled, and all the buffering resistance can be eliminated when the door is closed to be smaller than a preset angle (for example, smaller than 20 degrees) by releasing the oil pressure and setting the angle of the curved surface 732.
Referring to fig. 9 and 10, a second embodiment of the hinge device of the present invention, which is substantially the same as the first embodiment, also includes the leaf unit 2, the spindle 4 and the ring unit 5, except that: the second embodiment comprises two kit units 3.
In the embodiment, the first sheet 21 is in a shape of a letter 21274, and the second sheet 22 is arranged between the first sheets 21.
Referring to fig. 10, 11, 12 and 13, the sleeve unit 3 is respectively inserted into the first seat tube 211 and the second seat tube 221 from two opposite directions of the leaf unit 2 along the axis X direction, and rotates synchronously with the first leaf 21. Each kit unit 3 includes a tube 31 inserted into the first seat tube 211 and the second seat tube 221, a torsion spring 32 inserted into the tube 31, an end piece 33 rotatably engaged with the tube 31, two washers 34, and a limit bolt 35. The pipe 31 has a first pipe section 311 and a second pipe section 312 which are mutually engaged. The first tube segment 311 has a tooth notch 3111 formed on the inner surface, two fitting blocks 3112 extending from the end portion in a direction parallel to the axis X, and two outer flat surfaces 3113 formed on the outer surface and abutting against the inner flat surface 2111 of the corresponding first seat tube 211. The second pipe section 312 has two caulking grooves 3121 extending from the end portion in a direction parallel to the axis X and butt-fitted with the fitting block 3112, and two outer flat surfaces 3122 formed on the outer surface and abutting against the inner flat surfaces 2111 of the corresponding first seat pipe 211. The torsion spring 32 has two end portions 321, 322, two end coils 323 connected to the end portions 321, 322, and a middle coil 324 connected between the end coils 323. Each set of end coils 323 has at least two or more turns of tightly wound coils each separated by a first gap D1. The middle coil 324 has a plurality of turns each separated by a second gap D2. The first gap D1 is less than the second gap D2. The end piece 33 has a hexagonal hole 331 formed in one end surface and exposed to the outside of the pipe member 31, a recess 332 formed in the outer circumferential surface, a ring tooth 333 engaged with the tooth groove 3111 of the first pipe segment 311, and a groove 334 formed in the outer circumferential surface and into which the end 321 of the torsion spring 32 is inserted to be interlocked. After a hand tool (not shown) is fitted into the hexagonal hole 331, the torsion force of the torsion spring 32 can be changed by twisting the torsion spring 32 through the change of the rotation angle and the change of the engagement position of the tooth socket 3111 and the ring teeth 333. The washers 34 are respectively disposed in the opening of the second tube section 312 of the tube 31 and between the first tube section 311 and the second tube section 312 for stopping the torsion spring 32 and preventing the torsion spring 32 from being separated from the groove 334 of the end piece 33. The limiting bolt 35 is screwed into the first pipe section 311 of the pipe 31 and is inserted into the recess 332 of the end piece 33, so that the end piece 33 is limited in the first pipe section 311 of the pipe 31.
Referring to fig. 9, 10 and 12, the mandrel 4 includes a fixing member 41 positioned in the second seat tube 221 of the second sheet 22 and rotating synchronously with the second sheet 22, and two shaft sections 42 penetrating through the sleeve unit 3 and coupled with the fixing member 41 to form a linkage. The fixing member 41 has a square bolt hole 411 and a recess 412 arranged along the axis X direction, and two grooves 413 formed on two opposite sides along the axis X direction. In this embodiment, the groove 412 is a square groove. Each shaft segment 42 is inserted between the end coil 323 and the middle coil 324 of the torsion spring 32 along the axis X, and has a stud 421 and a rim 423 forming a notch 422. The stud 421 of the shaft segment 42 is engaged with the square bolt hole 411 and the groove 412 of the fixing member 41, and the notch 422 is connected to the groove 413, so that the ends 321 and 322 of the torsion spring 32 pass through the notch 422 and are inserted into the groove 413.
Referring to fig. 9, since the second leaf 22 is disposed between the v-shaped first leaves 21, when the hinge device according to the second embodiment of the present invention is connected to the objects 11 and 12, the required door gap size is equal to or slightly larger than the thickness of the first leaves 21, so that a door frame and a door leaf with a small gap between the door gap can be used. When the objects 11 and 12 are connected, the first reference surface 213 of the first leaf 21, the second reference surface 223 of the second leaf 22, or the edge 111 of the object 11, or the edge 121 of the object 12 is only required to abut against, so that the plurality of hinge devices can be linearly arranged in the vertical direction and the parallel direction relative to the object 11 or the object 12, thereby avoiding position errors when the hinge devices are installed, and improving the smoothness when the door leaf rotates.
Referring to fig. 9, 14 and 15, when the first leaf 21 is driven by external force to rotate around the axis X to open the door, the first leaf 21 drives the tube 31 of the kit unit 3 synchronously through the first seat tube 211, so that the tube 31 drives the end piece 33 to twist the end 321 of the torsion spring 32 synchronously during rotation, and when the second seat tube 221 of the second leaf 22 and the fixing piece 41 are fixed together with the end 322 of the torsion spring 32, the end coil 323 and the middle coil 324 of the torsion spring 32 rotate in the pressure accumulation direction, and generate trigger force capable of resisting the external force and being accumulated.
Therefore, when the external force is released, the torsion spring 32 releases the trigger force, and can provide an added restoring torsion force when the door is closed, so that the pipe 31 of the kit unit 3 and the first leaf 21 rotate in opposite directions.
For example, if the restoring force generated by each torsion spring 32 is 90Kg, the two torsion springs 32 of the two kit units 3 of the present embodiment can generate a trigger force (restoring torsion) of 90Kg +90 Kg-180 Kg after the external force is released, and is suitable for heavy doors. It should be noted that, in addition to the effect of adding the aforementioned restoring torsion, the present embodiment can further increase the torsion without changing the overall length of the torsion spring 32 by a special design that the first gap D1 of the end coil 323 of the torsion spring 32 is smaller than the second gap D2 of the middle coil 324, and taking the end coil 323 of each torsion spring 32 as a 3-turn tight coil as an example, the torsion springs with the same gap can generate 15Kg more trigger force (restoring torsion force) per one rotation of one scale, and then one torsion spring 32 of the present invention can generate 15 × 3 to 45Kg trigger force (restoring torsion force) per one rotation of one scale, thereby, when the end piece 33 drives the torsion spring 32 to rotate 1 more scale through the hexagonal hole 331, for example, when scale 1 rotates to scale 2, the torsion spring 32 of the present invention can generate the trigger force (return torsion force) of 15 × 3 × 2 — 90Kg, when the scale 2 rotates to the scale 3, the torsion spring 32 of the present invention can generate the trigger force (return torsion force) of 15 × 3 — 135Kg, and when the scale 3 rotates to the scale 4, the torsion spring 32 of the present invention can generate the trigger force (return torsion force) of 15 × 3 × 4 — 180 Kg. Therefore, a 300Kg heavy door originally needs three hinge devices to push, but the invention can push only by using a second embodiment (180Kg × 2 — 360 Kg).
Since the hinge device of the present invention has no directional limitation during installation, when the second leaf 22 is driven by external force to rotate around the axis X to open the door, the second leaf 22 will synchronously drive the fixing member 41 of the mandrel 4 through the second seat tube 221, so that the fixing member 41 synchronously drives the shaft section 42 to twist the end 322 of the torsion spring 32 during rotation, and under the condition that the first seat tube 211 of the first leaf 21, together with the end piece 33, and the end 321 of the torsion spring 32 are fixed, the end coil 323 and the middle coil 324 of the torsion spring 32 can also rotate in the pressure accumulation direction, and generate a trigger force capable of resisting the external force and accumulating.
Thereby, when the external force is released to close the door, the torsion spring 32 releases the trigger force, and can provide an added restoring torsion force to rotate the tube 31 of the kit unit 3 and the first leaf 21 in the opposite direction when the door is closed.
It should be noted that, since the first gap D1 of the three close end coils 323 of the torsion spring 32 is smaller than the second gap D2 of the middle coil 324, the torsion spring 32 can increase the expected torsion value by a factor to increase the trigger force (restoring torsion).
In addition, only by rotating the end piece 33 of the kit unit 3 with a tool (not shown), the end piece 33 twists the torsion spring 32 to a predetermined angle, so as to increase or decrease the torsion of the torsion spring 32, thereby achieving the purpose of controlling the door closing force, and further improving the smoothness of the door closing.
Referring to fig. 16, a third embodiment of the present invention is substantially the same as the previous embodiments, and mainly includes assembling the sleeve unit 3 and the sleeve unit 7 with the sheet unit 2, the mandrel 4, and the ring unit 5.
Therefore, when the first blade 21 or the second blade 22 is driven by an external force to rotate around the axis X to open the door, the operation principle and the efficacy of the kit unit 3 can be referred to the second embodiment, and the operation principle and the efficacy of the kit unit 7 can be referred to the first embodiment.
When the external force is released, the torsion spring 32 of the kit unit 3 also releases the aforementioned trigger force, so as to provide a restoring torsion force when the door is closed, so that the tube 31 of the kit unit 3, the tube 71 of the kit unit 7, the friction member 73 and the first leaf 21 rotate in opposite directions. Additional details will not be set forth in order to provide those skilled in the art with a understanding of the above description.
Referring to fig. 17, a fourth embodiment of the present invention is substantially the same as the previous embodiments, and mainly includes the assembly of the sleeve unit 3, the sleeve unit 6, the leaf unit 2, the mandrel 4, and the ring unit 5.
Therefore, when the first leaf 21 or the second leaf 22 is driven by external force to rotate around the axis X to open the door, the operation and efficacy of the kit unit 3 can be referred to the second embodiment, and the operation and efficacy of the kit unit 6 can be referred to the first embodiment. Additional details will not be set forth in order to provide those skilled in the art with a understanding of the above description.
Referring to fig. 18, another aspect of the cartridge unit 6 described in the previous embodiment is illustrated. The kit unit 6 does not include the distal end operator 63 shown in fig. 4, but similarly includes a tube 61 inserted through the first and second seat tubes 211 and 221 and interlocked with the first seat tube 211, an oil hydraulic module 62 inserted through the tube 61, a proximal end operator 64 inserted through the tube 61 and interlocked with the tube 61, and an end fitting 65 enclosing one end of the tube 61.
Therefore, when the tube 61 is driven, the proximal acting element 64 will press the proximal matching surface 434 of the shaft segment 43 by the proximal slope 641 during the rotation process, so that the shaft segment 43 pushes the top pin 622 to press the hydraulic cylinder 621, and the pressing surface 432 compresses the elastic element 623, thereby generating the trigger force against the external force. Or when the fixing member 41 is driven, the shaft segment 43 is synchronously driven, so that the shaft segment 43 is pushed against the proximal inclined surface 642 of the proximal acting element 64 by the proximal engaging surface 434, the ejector pin 622 is pushed to press the ejector pin 6213 of the oil cylinder 621 to retract to generate buffering resistance, and the pressing surface 432 is used to compress the elastic element 623 to generate triggering force resisting the external force. Similarly, additional details will not be set forth, as those skilled in the art will appreciate the above description with the understanding that the present disclosure is to be considered an exemplification of the principles of the invention.
Referring to fig. 19 and 20, a fifth embodiment of the present invention is substantially the same as the first embodiment, and mainly includes the assembly of the sleeve unit 6, the sleeve unit 7, the leaf unit 2, the mandrel 4, and the ring unit 5. The difference lies in that:
the fixing member 41 can be turned up and down by 180 degrees and assembled with the shaft section 44 through the opening below the second seat tube 221 of the second leaf 22. Thereby, the square bolt hole 411 of the fixing member 41 can be engaged with the bolt of the shaft section 43 to form an interlocking action, and the shaft section 44 can be engaged with the bolt hole 440 of the shaft section 43 and the convex portion 442 to be in frictional contact with the corresponding frictional curved surface 732 of the friction member 73.
Referring to fig. 21 and 22, a sixth embodiment of the present invention is substantially the same as the second embodiment, and mainly the sleeve unit 3 is assembled with the sheet unit 2, the mandrel 4 and the ring unit 5. The difference lies in that:
the fixing member 41 can be turned up and down by 180 degrees and assembled through the opening below the second seat tube 221 of the second sheet 22. Therefore, the fixing member 41 can also be coupled and linked by the square bolt hole 411, the groove 412 and the bolt 421 of the shaft segment 42, and the groove 413 is connected to the notch 422 of the shaft segment 42, so that the ends 321 and 322 of the torsion spring 32 pass through the notch 422 and are inserted into the groove 413.
Referring to fig. 23 and 24, each of the spacing groups 52 of the ring unit 5 is not limited to have only one spacing ring 521, and may also have two spacing rings 521, and the ring walls 522 of the two spacing rings 521 of each spacing group 52 are inserted into the adjacent first seat pipe 211 and the second seat pipe 221, so that the ring edges 523 of the two spacing rings 521 are adjacent to and blocked between the first seat pipe 211 and the second seat pipe 221.
Thereby, the collar 51 may be a Polyoxymethylene (POM) or teflon (PTFE) material for improving the lubrication between the first seat tube 211, the second seat tube 221 and the tube members 61, 71 of the kit units 6, 7 and reducing the resistance. The spacer set 52 is made of a metal material, such as an aluminum material, which can reduce the friction coefficient, improve the wear resistance, and reduce the wear, and the annular edge 523 exposed between the first seat tube 211 and the second seat tube 221, and the first seat tube 211 and the second seat tube 221 are made of a metal material, which tends to be consistent in texture and visual effect, so as to further improve the overall aesthetic property.
Referring to fig. 25, another aspect of the kit unit 3 in the second, third, fourth and sixth embodiments is described. Wherein:
