the outer side of the convex part 5 is provided with a bulge 51, the lower surface of the convex part 5 is provided with a step 52, the upper surface of the base 2 is provided with a concave part 6 which is used for accommodating the lower part of the positioning seat 4 and is matched with the convex part 5, the matching means that the convex part 5 can rotate in the concave part 6 to realize the clamping between the convex part and the concave part, the concave part 6 comprises,
a groove 61 located on the inner side wall or the outer side wall of the recess 6 and cooperating with the protrusion 51, the groove 61 comprising a longitudinal groove 611 and a circumferential groove 612 communicating with each other, such that the protrusion 51 can enter along the longitudinal groove 611 and be accommodated in the circumferential groove 612; when installing the cylinder, it is possible to first move the cylinder downwards towards the glass, so that the protrusions 51 reach the bottom of the longitudinal grooves 611 along the longitudinal grooves 611, and then rotate the cylinder, so that the protrusions 51 rotate into the circumferential grooves 612 and are in place;
the matching means that the sizes and the shapes of the matching surfaces of the groove 61 and the protrusion 51 are matched, so that the protrusion 51 can rotate and be clamped in the groove 51; it should be understood that the longitudinal groove 611 and the circumferential groove 612 can be used as positioning surfaces for the protrusion 51 to rotate to position, and therefore, the longitudinal groove 611 and the circumferential groove 612 can be made to be closed (having both left and right sides in the groove width direction), as shown in fig. 3; it may be made open (at least no left or right side in the groove width direction), as shown in fig. 7; as long as the left side wall or the right side wall of one of the two can form a positioning surface;
a sidewall opening 63 located on a sidewall of the recess 6 and penetrating a sidewall direction of the recess 6; and
an elastic member 64 including an extension portion 641 extending upward from the bottom of the recess 6 and a pressing end portion 642 extending at least to the side wall opening 63 of the base 2; when the elastic element 64 is in a deformed state, that is, the elastic element 64 is subjected to a downward pressure so that the height of the upper surface of the elastic element 64 is lower than the bottom surface of the concave portion 6, the convex portion 5 of the positioning seat 4 can rotate forward in the concave portion 6 of the base 2, so that the protrusion 51 rotates into the groove 61 and is in place, and further, the step 52 rotates forward above the elastic element 64; when the elastic element 64 returns to the original state, the elastic element 64 is used for being clamped on the step 52 rotated to the upper side in the forward direction, so as to limit the reverse rotation of the positioning seat 4 relative to the base 2.
In the invention, the forward rotation and the reverse rotation are opposite, and the forward rotation can be clockwise rotation, and the reverse rotation can be anticlockwise rotation; or the forward rotation can be anticlockwise rotation, and the reverse rotation can be clockwise rotation.
In the present invention, the material and shape of the stud are not particularly limited, and may be metal, plastic or a combination of the two, and the cylinder may be a single claw, a multi-claw or a screw.
In the present invention, the pressing end 642 may be located inside the sidewall opening 63 or may extend out of the sidewall opening 63. To facilitate pressing onto the resilient element 64, the pressing end 642 of the resilient element 64 preferably extends outwardly beyond the sidewall opening 63, i.e. beyond the outer sidewall of the base 2, due to the small space between the stud and the glass.
Further, the pressing end 642 of the elastic member 64 is of a retractable or foldable structure such that the pressing end 642 can extend outward of the sidewall opening 63 or can be retracted and accommodated in the sidewall opening 63. When pressing is needed, the pressing end 642 can extend out of the outer side wall of the base 2 by stretching or folding, and when pressing is not needed, the pressing end 642 can be accommodated in by compressing or folding, so that the pressing end 642 can be prevented from being contacted due to misoperation, and looseness between the cylinder 1 and the base 2 can be avoided.
In the present invention, the above folding structure may be an upwardly folded structure, as shown in fig. 5; a side folded configuration is also possible as shown in fig. 6. It should be understood that the folding structure is preferably one-way folded, so that when pressed downward, the pressing end 642 is not folded against the extension 641, thereby bringing the extension 641 downward, and enabling the protrusion 51 to rotate along the upper surface of the extension 641 into or out of the groove 61.
In the present invention, the extension 641 may extend radially outward from the center of the concave portion 6, as shown in fig. 5; or may extend along the circumferential direction of the recess 6, as shown in fig. 3. One installation process of the structural stud is as follows:
1) the projection 51 is aligned with and placed inside the notch of the longitudinal groove 611; at this time, due to the presence of the extension 641, the projection 51 cannot reach directly the bottom of the longitudinal groove 611;
2) the pressing end 642 is lightly pressed downward so that the pressing end falls below the bottom surface of the recess 6, at which time the projection 51 may fall to the bottom of the longitudinal groove 611;
3) keeping the pressing state of the pressing end 642, and rotating the cylinder 1 in the positive direction (clockwise) until the protrusion 51 rotates into the annular groove 612 and is attached in place;
4) when the pressing end 642 is released, the pressing end 642 is reset and clamped on the step 53 at the bottom of the cylinder 1, so as to limit the reverse (counterclockwise) rotation of the positioning seat 4 relative to the base 2, and the cylinder 1 and the base 2 are installed in place.
The disassembly process is the reverse of the installation process described above and will not be described in detail.
In the present invention, it is particularly advantageous to provide the extension 641 to extend upwardly around the circumferential edge of the recess 6. At this time, a slope 613 inclined upward toward the longitudinal groove 611 may be provided on the upper surface of the circumferential groove 612. It should be understood that the ramp may be a linear ramp or an arcuate ramp, which primarily serves as a guide for guiding the protrusion into the circumferential groove.
With the above-mentioned slope structure, during the positive rotation of the protrusion 5 in the recess 6, the at least one protrusion 51 has a travel path along the extension, so that the at least one protrusion 51 can be pressed onto the extension on at least a part of the travel path. Therefore, during the installation process, without pressing the pressing end, the cylinder 1 can be directly rotated, so that the protrusion 51 moves downward along the rotation edge of the inclined plane by the downward pressure of the inclined plane, and the protrusion 51 rotates along the surface of the extension 641 and presses the extension 641 downward, and finally the protrusion 51 enters and is locked in the groove 61. The specific installation process is as follows:
1) the projection 51 is aligned with and placed inside the notch of the longitudinal groove 611; at this time, due to the presence of the extension 641, the projection 51 cannot reach directly the bottom of the longitudinal groove 611;
2) rotating the cylinder 1 in a forward (clockwise) direction so that the protrusion 51 is inclined downward into the annular groove 612 along the inclined surface 613 thereof, and at the same time, the protrusion 51 rotates along the surface of the extension 641 and presses down the extension 641;
3) the protrusion 51 presses down the extension 641 while rotating until the protrusion 51 rotates into the annular groove 612 and fits in place;
4) at this time, the step 53 at the bottom of the column 1 rotates to the position above the pressing end 642, the pressing end 642 automatically resets and is clamped on the step 53 at the bottom of the positioning seat 4 to limit the reverse (counterclockwise) rotation of the positioning seat 4 relative to the base 2, and the column 1 and the base 2 are installed in place.
The dismounting process of the structural nail column is the same as the above, and is not repeated.
In the present invention, alignment marks for alignment during installation and/or after in-place alignment may be respectively disposed on the outer sidewalls of the positioning seat 4 and the base 2, and the alignment mark disposed on the positioning seat 4 corresponds to the alignment mark disposed on the base 2. The alignment mark for alignment during installation is used for prompting a user of a correct installation position and reducing the operation time of the user needing alignment in the operation process. The alignment mark for aligning after being in place is used for prompting a user of a correct in-place position, and the phenomenon that the column body 1 falls off from the base 2 due to the fact that the column body is not in place is avoided.
In the present invention, the number of the grooves 61 may be single or plural, and preferably, the grooves are uniformly distributed along the circumferential direction of the recess 6. Adopt circumference equipartition, can be so that the atress between cylinder 1 and the base 2 is even, and this is particularly advantageous to the hoop groove that has the inclined plane, because the hoop groove is less with bellied lifting surface, and the size of required screw in power is changed, through circumference equipartition structure, can improve overall structure's stability.
It should be understood that the resilient member 64 and the recess 6 according to the present invention may be formed as a separate piece or as an integral injection molded piece. The split structure may be exemplified by using a metal elastic sheet as the elastic element 64, and the metal elastic sheet is embedded in the concave portion 6 by insert molding. When an integral injection molded part is used, in order to increase the elasticity and strength of the elastic element 64 made of plastic, a reinforcing insert may be provided in the elastic element 64.
Further, the number of the longitudinal grooves 611 is at least two, at least two of the longitudinal grooves 611 have different groove widths, and the width of the protrusion 51 matches the groove width of the longitudinal grooves 611. As shown in fig. 4, each longitudinal groove hasWith different groove widths L1、L2And L3. The matching means that the matching surfaces are identical in shape and size, the foolproof and mistake-proof effects can be achieved, and the cylinders can be conveniently and quickly clamped into the base.
In the schematic diagram 1 of the present invention, the outer side wall of the positioning seat 4 is flush with the outer side wall of the base 2, so as to meet the requirement of the external shape. It should be understood that the outer side wall of the positioning seat 4 may also be retracted to make its outer contour dimension smaller than or equal to the convex portion 5, and when the outer contour shapes of the two are consistent, the positioning seat 4 may be merged into the convex portion 5 to form an integral structure.
In addition, as shown in fig. 3 and 7 of the present invention, the grooves 61 are disposed on the inner side wall of the concave portion 6, wherein the grooves 61 may be formed to protrude inward from the side wall, or may be disposed to be recessed outward from the side wall, and the structural position of the protrusions 51 used in cooperation with each other needs to be adjusted accordingly. Moreover, as shown in fig. 8 and 9, the base 2 and the column 1 used in combination can also have a groove 61 on the outer side wall of the concave part 6, in this case, unlike the other embodiment in which the protrusion 51 is arranged on the outer side wall of the convex part 5, the protrusion 51 of this embodiment is located on the outer side of the convex part 5, and there is a certain gap between the two.
The above description specifically describes a glass assembly with a stud according to the present invention, but the present invention is not limited to the above description, and therefore, any improvements, equivalent modifications, substitutions, etc. made in accordance with the technical gist of the present invention are intended to be within the scope of the present invention.
