[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0021] Please see Figure 1-5 This utility model provides a technical solution: an elevator car top guardrail, including a column body 1 and a crossbar body 3. The side of the column body 1 is fixedly provided with threaded connection holes 2. There are several sets of threaded connection holes 2. The crossbar body 3 is threadedly connected inside the threaded connection holes 2. One end of the crossbar body 3 is threadedly sleeved with a connector 4. One end of the connector 4 is threadedly sleeved with the same crossbar body 3. The crossbar body 3 includes an outer sleeve 10. The two ends of the outer sleeve 10 are fixedly provided with threaded slot holes 11. The two ends of the outer sleeve 10 are threadedly sleeved with levers 12.

[0022] In this embodiment, the column body 1 and the crossbar body 3 are assembled by threaded connection, eliminating the need for additional drilling and making installation convenient. A guardrail can be formed on the car top. The crossbar body 3 uses a screw lever 12 and an outer sleeve 10 in cooperation, and the overall length can be adjusted by rotating the screw lever 12 at both ends. By using multiple adjustable crossbar bodies 3 connected to each other, it can be adapted to elevators of different sizes without cutting the crossbars, which is convenient for installation. This design method uses a threaded connection between the crossbar and the column, eliminating the need for additional drilling. The crossbar uses multiple adjustable crossbar bodies 3 connected by threads, which can be adapted to elevators of different sizes. The lack of cutting makes installation more convenient and improves installation efficiency.

[0023] Specifically, one end of the lever 12 is fixedly connected to a rotating block 13, which adopts a hexagonal block design.

[0024] In this embodiment, the rotating block 13 facilitates the adjustment of the rotating lever 12.

[0025] Specifically, a fixed base plate 5 is fixedly connected to the lower end of the column body 1, and threaded fixing holes 6 are fixedly opened at the four corners of the fixed base plate 5.

[0026] In this embodiment, the fixed base plate 5 facilitates the fixing of the column body 1 to the top of the elevator.

[0027] Specifically, the connector 4 includes a connecting sleeve 7, a partition block 8 is fixedly connected to the center of the connecting sleeve 7, and threaded grooves 9 are provided on the inner walls of both ends of the connector 4.

[0028] In this embodiment, the connecting piece 4 can be separated at both ends by the partition block 8 to connect the two crossbar bodies 3.

[0029] Specifically, a telescopic column 14 is slidably sleeved on the upper end of the column body 1, a protective top cover 15 is fixedly connected to the upper end of the telescopic column 14, a protective spring 16 is sleeved on the outer surface of the telescopic column 14, one end of the protective spring 16 is fixedly connected to the column body 1, and the other end of the protective spring 16 is fixedly connected to the protective top cover 15.

[0030] In this embodiment, the telescopic column 14 and the protective top cover 15 are slidably connected. Under the elastic action of the telescopic column 14, the telescopic column 14 is elastically connected. During the elevator's lifting and lowering process, when the protective top cover 15 is subjected to force, it can compress the protective spring 16, causing the telescopic column 14 to descend. This converts the force into elastic deformation, thus providing a certain degree of protection and preventing direct force on the column body 1, which could lead to deformation and damage. This design can provide a certain degree of protection for the guardrail column during the elevator's lifting and lowering process, preventing damage to the column due to force. It has a good protective effect. In use, the four column bodies 1 are fixed to the four corners of the elevator top by the fixed base plate 5. At this time, several crossbar bodies 3 are connected into a whole by the connector 4. Then, by adjusting the length of the crossbar bodies 3 at both ends, they are threadedly connected to the column bodies 1 to complete the installation. The whole process does not require cutting or drilling, saving a lot of time and improving installation efficiency.

[0031] 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.
