The locking component is connected with the connecting part and the main body and is used for propping the connecting part towards the main body direction and propping the main body towards the connecting part direction so as to prevent the fixed part from being separated from the movable space.

Some embodiments of the present application will be described below with reference to the accompanying drawings. The embodiments described below and features of the embodiments may be combined with each other without conflict.

Fig. 1 provides a supporting structure 200, where the supporting structure 200 includes a disc buckle 100, a single push rod 40 and a plug 50, the disc buckle 100 has a preset axis O, the disc buckle 100 is provided with a through hole 111, the through hole 111 penetrates through opposite ends of the disc buckle 100, and the axis of the through hole 111 coincides with the preset axis O. The disc buckle 100 is sleeved on the single ejector rod 40 through the through hole 111, and the through hole 111 is in clearance fit with the single ejector rod 40. The axis of the single ejector rod 40 coincides with the preset axis O, and along the length direction of the single ejector rod 40, a plurality of mounting holes 41 are formed in the single ejector rod 40, and the plurality of mounting holes 41 are arranged at intervals and are matched with the plug pins 50 in size. The latch 50 extends into the mounting hole 41 and can abut against the bottom of the disc buckle 100 to block the disc buckle 100 from moving downward. Because the through hole 111 is in clearance fit with the single push rod 40, when the disc buckle 100 is mounted on the single push rod 40, the disc buckle 100 can move along the length direction of the single push rod 40, so that the position of the disc buckle 100 relative to the single push rod 40 can be adjusted, and the height of the disc buckle 100 can be adjusted. Because the disc buckles 100 are connected with the horizontal cross bars when the scaffold is built, the two ends of the cross bars are respectively arranged on different disc buckles 100, so that the relative positions of two adjacent single ejector rods 40 are limited. Therefore, when the scaffold is constructed, the weight of the cross bar is borne by the disc buckle 100, and the disc buckle 100 can be prevented from moving upwards, so that when the scaffold is constructed, the disc buckle 100 has stability in the length direction of the single ejector rod 40.

In fig. 2 and 3, some embodiments of the present application provide a support structure 200, including a disc buckle 100 and a single ejector 40, where the disc buckle 100 can move along the length direction of the single ejector 40, and can fix the disc buckle 100 to the single ejector 40 in a proper position. The disc buckle 100 includes a main body 10, a fixing member 20, and a locking assembly 30. The main body 10 has a preset axis O, the main body 10 is provided with a through hole 111, the through hole 111 penetrates through two ends of the main body 10, and the axis of the through hole 111 coincides with the preset axis O. The main body 10 is sleeved on the single ejector rod 40 through the through hole 111, so that the axis of the single ejector rod 40 is also coincident with the preset axis O, and the through hole 111 is in clearance fit with the single ejector rod 40, so that a movable space 14 is formed between the main body 10 and the single ejector rod 40. The fixing member 20 includes a fixing portion 21 and a connecting portion 22, the connecting portion 22 is disposed on one side of the fixing portion 21, the fixing portion 21 is disposed on one side of the single ejector 40, and at least a portion of the fixing portion 21 extends into the movable space 14 and can be abutted against the single ejector 40 and the through hole 111 to fill the movable space 14 between the main body 10 and the single ejector 40, so as to clamp the main body 10 and the single ejector 40 to define a relative position between the main body 10 and the single ejector 40. The locking component 30 is located between the main body 10 and the fixing piece 20, the locking component 30 presses the connecting portion 22 towards the main body 10, and the locking component 30 presses the main body 10 towards the connecting portion 22, so that the connecting portion 22 and the main body 10 move towards each other, and the fixing portion 21 can be pushed to extend into the movable space 14, so that the fixing portion 21 is prevented from being separated from the main body 10.

The fixing piece 20 stretches into the movable space 14 and can be abutted against the single ejector rod 40 and the through hole 111, so that not only can the horizontal shaking caused by the existence of the movable space 14 between the single ejector rod 40 and the main body 10 be slowed down, but also the movable space 14 is utilized to tightly abut against the single ejector rod 40 and the through hole 111 through the fixing piece 20 so as to limit the relative position of the main body 10 and the single ejector rod 40. This also means that the direction in which the body 10 moves upwards relative to the single ejector 40 is also limited. The main body 10 can be stably transported without being separated from the single lift pins 40 when transporting the support structure 200, and the occurrence of sliding of the main body 10 with respect to the single lift pins 40 and even collision of the main body 10 with a transport vehicle, which may be a truck, can be reduced when transporting the support structure 200. Because the main body 10 and the single ejector rod 40 do not need to be separated during transportation, the main body 10 and the single ejector rod 40 do not need to be specifically separated during scaffold disassembly, the scaffold disassembly speed can be improved, the main body 10 does not need to be reinstalled during scaffold establishment next time, the position of the main body 10 is regulated, and the installation efficiency is high. Further, since the main body 10 and the single jack 40 are fixed by the fixing member 20 being abutted, the position of the main body 10 is not limited by the mounting hole 41 on the single jack 40, so that the main body 10 can be mounted at an arbitrary position in the longitudinal direction of the single jack 40, and the height of the main body 10 mounted on the single jack 40 can be adjusted steplessly.

The fixing member 20 may be located above the main body 10 and extend into the movable space 14 from top to bottom to achieve fixing of the main body 10 to the single jack 40.

Alternatively, in some embodiments, the fixing member 20 is located below the main body 10 and extends into the movable space 14 from bottom to top to achieve fixing of the main body 10 to the single jack 40.

Alternatively, in some embodiments, the number of fixtures 20 is two, and the two fixtures 20 are disposed opposite along the preset axis O. It will be appreciated that the number of fixtures 20 is not limited to two, but may be one, three, four, etc. When the number of the fixing members 20 is one, the axis of the single jack 40 is not coincident with the preset axis O. The number of locking assemblies 30 may be the same as that of the fixing members 20 such that each locking assembly 30 abuts against one fixing member 20, or the number of locking assemblies 30 may be different from that of the fixing members 20, for example, the number of locking assemblies 30 is one, and a plurality of fixing members 20 can be simultaneously pushed to move toward the movable space 14.

Referring to fig. 3, 4 and 5, optionally, in some embodiments, the fixing portion 21 has an inner surface 211 and an outer surface 212 opposite to each other, the inner surface 211 is located near the preset axis O, the inner surface 211 is used for fitting with a sidewall of the single lift pin 40, the outer surface 212 is used for contacting with a wall of the through hole 111, and the connecting portion 22 is disposed on the outer surface 212. The outer surface 212 is disposed obliquely with respect to the inner surface 211, and the outer surface 212 gradually approaches toward the preset axis O in the downward-upward direction. When the fixing portion 21 extends into the movable space 14 from bottom to top, the inner surface 211 of the fixing portion 21 is attached to the side wall of the single jack 40, and the inner wall of the through hole 111 abuts against the outer surface 212. Since the outer surface 212 is inclined, when the outer surface 212 contacts with the inner wall of the through hole 111, a component force is generated toward the preset axis O, so that a friction force between the inner surface 211 and the single jack 40 is increased, and the fixing portion 21 is connected with the main body 10 through the locking assembly 30, so that the main body 10 can be stably mounted on the single jack 40.

Referring to fig. 6, alternatively, in other embodiments, the hole wall of the through hole 111 is inclined with respect to the preset axis O, and when the fixing portion 21 extends into the movable space 14 from bottom to top, the hole wall of the through hole 111 contacts the outer surface 212 and exerts a force component on the outer surface 212 toward the preset axis O, so as to increase the friction between the inner surface 211 and the single ejector pin 40.

Referring to fig. 7, in other embodiments, the outer surface 212 and the walls of the through hole 111 are disposed obliquely with respect to the predetermined axis O and have uniform slopes. Since the slope of the outer surface 212 is identical to that of the hole wall of the through hole 111, the contact area between the outer surface 212 and the hole wall of the through hole 111 can be increased, thereby improving the stability of the fixing portion 21 and the main body 10.

Optionally, in some embodiments, the outer surface 212 and the inner surface 211 are both cambered surfaces, and the axes of both cambered surfaces coincide with the preset axis O. The radians of the outer surface 212 and the inner surface 211 are smaller than pi, so that when the fixing portion 21 moves towards the single ejector rod 40 along the horizontal direction, the inner surface 211 can be attached to the side face of the single ejector rod 40, and when the two fixing portions 21 are located at the same height and are oppositely arranged along the preset axis O, interference between the two fixing portions 21 does not occur when the fixing portion 21 moves towards the single ejector rod 40 due to overlarge radian.

Optionally, in some embodiments, the inner surface 211 is provided with serrations 23 (as shown in fig. 4), and the serrations 23 contact with the side wall of the single lift pin 40, so as to increase the friction between the side wall of the single lift pin 40 and the inner surface 211 by increasing the surface roughness of the inner surface 211, and further increase the stability of the mounting of the main body 10 to the single lift pin 40.

Referring to fig. 8, optionally, in some embodiments, a friction layer 24 is disposed between the inner surface 211 and the single lift pin 40, and the friction coefficient of the friction layer 24 is greater than that of the inner surface 211, so that under the same conditions, the friction force between the friction layer 24 and the side wall of the single lift pin 40 is greater than that of the inner surface 211 and the side wall of the single lift pin 40. The friction layer 24 can elastically deform, when the fixing portion 21 extends into the movable space 14, the friction layer 24 is continuously pressed by the inner surface 211 and the side wall of the single ejector rod 40 through pushing of the outer surface 212, the friction layer 24 elastically deforms, and pressure is applied to the side wall of the single ejector rod 40, so that friction force between the friction layer 24 and the side wall of the single ejector rod 40 is further improved, and stability of the main body 10 mounted on the single ejector rod 40 is improved. Alternatively, the material of the friction layer 24 is rubber.

In some embodiments, locking assembly 30 has one end abutting platen buckle 12 and the other end abutting connector 22 to push retainer 21 into active space 14 and block body 10 from separating from retainer 20.

In other embodiments, the main body 10 further includes a limiting portion 13, the limiting portion 13 is disposed on one side of the connecting cylinder 11, and the limiting portion 13 is located on one side of the disc buckle 12 close to the fixing member 20, and one end of the locking component 30 abuts against the limiting portion 13, and the other end abuts against the connecting portion 22, so as to achieve connection between the main body 10 and the fixing member 20.

So that the limiting part 13 and the connecting part 22 are respectively applied with opposite pressure, the fixing part 21 can stably extend into the movable space 14, and the fixing piece 20 is stably connected with the main body 10.

Alternatively, in some embodiments, the lower end diameter of the pressing member 31 is larger than the upper end diameter, so that the pressing member 31 has a shape similar to a bolt shape, so that the upper end of the pressing member 31 can face the stopper 13 while the lower end of the pressing member 31 can press the lower end of the connecting portion 22.

Referring to fig. 9, alternatively, in some embodiments, the pressing member 31 is a bolt and has an external thread, and the locking member 32 is a nut and has an internal thread that is adapted to the external thread of the bolt.

Thereby realizing the limit of the main body 10 and the fixing member 20. It is to be understood that the pressing surface 3211 is not limited to an arc shape, as long as the distance between the pressing surface 3211 and the rotation axis of the cam portion 321 is different, for example, the pressing surface 3211 is formed by connecting multiple planes, and each plane is different from the rotation axis of the cam portion 321.

Because of the space between the connecting portion 22 and the limiting portion 13, when the fixing portion 21 is worn and thinned due to long-term repeated use, the depth of the fixing portion 21 extending into the movable space 14 can be increased, so that the fixing portion 21 can still stably abut against the side wall of the single ejector rod 40 and the wall of the through hole 111. The locking assembly 30 can correspondingly adjust and limit the positions of the connecting portion 22 and the limiting portion 13, for example, when the locking assembly 30 is a bolt and a nut, after increasing the depth of the fixing portion 21 extending into the movable space 14, the position of the nut relative to the bolt is correspondingly adjusted, so that the locking assembly 30 can stably limit the positions of the main body 10 and the fixing member 20.

In other embodiments, the connecting portion 22 contacts the limiting portion 13 when the locking assembly 30 limits the relative position of the fixing member 20 and the main body 10.

In summary, in the embodiment of the present application, the supporting structure 200 is provided, at least a portion of the fixing portion 21 is extended into the movable space 14 by using the movable space 14 formed by the clearance fit between the through hole 111 and the single ejector 40, and the fixing portion 21 is pressed against the sidewall of the single ejector 40 and the hole wall of the through hole 111, and the locking assembly 30 is used to define the relative position between the main body 10 and the fixing member 20, so that the buckle 100 can be stably fixed on the single ejector 40, and the position of the buckle 100 relative to the single ejector 40 can be arbitrarily adjusted.

Embodiments of the present application also provide a formwork frame including a support structure and a cross bar. One end of the cross rod is connected with the disc buckle of one supporting structure, and the other end of the cross rod is connected with the disc buckle of the other supporting structure, so that a plurality of supporting structures can be connected with each other to form the template frame.

In addition, those of ordinary skill in the art will recognize that the above embodiments are presented for purposes of illustration only and are not intended to be limiting, and that suitable modifications and variations of the above embodiments are within the scope of the disclosure of the present application.
