Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 One embodiment of this utility model provides an elevator car wall connecting bolt assembly, including a bolt mating seat 4 for support, and a threaded guide groove 5 for mating is provided at the center of the upper end face of the bolt mating seat 4.

[0025] Anti-slip protrusions 1 are equidistantly arranged on the upper end face of the bolt mating seat 4;

[0026] Support device 3 is threadedly connected to the inner end face of bolt mating seat 4 via threaded guide groove 5;

[0027] Guide device 2 is threadedly slidably connected to the outer end face of support device 3.

[0028] The guide device 2 includes a hexagonal slide sleeve 21, a limit slider 22 is rotatably engaged at the center of the inner end face of the hexagonal slide sleeve 21, and six sets of internal hexagonal threaded shafts 23 are equidistantly arranged at the bottom of the inner end face of the hexagonal slide sleeve 21.

[0029] The support device 3 includes a hexagonal pressure plate 31. A threaded connecting shaft 32 is fixedly installed at the center of the lower end face of the hexagonal pressure plate 31, and a protective gasket 33 is installed near the outside of the lower end face of the hexagonal pressure plate 31. A hexagonal retaining shaft 35 is installed at the center of the upper end face of the hexagonal pressure plate 31, and a threaded slide groove 36 is opened at the center of the inner end face of the hexagonal retaining shaft 35. Six sets of fixing slide grooves 34 are equally spaced on the side end face of the hexagonal retaining shaft 35.

[0030] The hexagonal pressure plate 31 is adapted to the threaded guide groove 5 through the threaded connecting shaft 32 and is then threadedly connected to the upper end face of the bolt mating seat 4. The threaded connection between the threaded connecting shaft 32 and the threaded guide groove 5 can effectively improve the stability of the subsequent limiting of elevator parts by the threaded connecting shaft 32.

[0031] The hexagonal sliding sleeve 21 is adapted to the internal hexagonal threaded shaft 23 through the fixed sliding groove 34 and then slidably engaged on the outer end face of the hexagonal locking shaft 35. The sliding limit between the internal hexagonal threaded shaft 23 and the fixed sliding groove 34 can effectively improve the stability of the subsequent external displacement of the hexagonal sliding sleeve 21 on the hexagonal locking shaft 35.

[0032] The limit slider 22 is threadedly connected to the threaded groove 36. The anti-slip protrusion 1 and the protective pad 33 are both made of rubber. The threaded connection between the limit slider 22 and the threaded groove 36 facilitates the quick and convenient adjustment of the height of the hexagonal sleeve 21 relative to the hexagonal retaining shaft 35, effectively improving the adaptability of the threaded connecting shaft 32 to the limit of elevator parts.

[0033] Working principle: During use, the operator can position the elevator component in a suitable location, then align the bolt mating seat 4 with the pre-drilled hole, and insert the threaded connecting shaft 32 through the pre-drilled hole into the threaded guide groove 5. The operator can then use an external tool to screw into the outside of the hexagonal sliding sleeve 21 to install the elevator component. If it needs to be installed in a deeper countersunk hole, the operator can use a tool to rotate the upper part of the limiting slider 22. At this time, the limiting slider 22 can be threadedly connected to the threaded slide groove 36, thereby driving the hexagonal sliding sleeve 21 to rise outside the hexagonal retaining shaft 35, thereby increasing the mating height of the hexagonal sliding sleeve 21. After adjustment, the operator can continue to limit the tool to the outside of the hexagonal sliding sleeve 21 to perform the limiting operation on the elevator component.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
