[0002] In the existing Chinese patent database, a patent named "An Elevator Car Touch Panel" is disclosed, with application number CN202221782373.5 and application date 2022-07-11. An elevator car touch panel comprises an installation shell embedded in the elevator, the surface of the installation shell is concave with a receiving groove, a touch panel body is movably installed in the receiving groove, slots are provided on the inner wall surfaces on both sides of the receiving groove, and positioning holes are provided on the inner wall surfaces of the two slots. Insert blocks are fixedly installed on the two side ends of the touch panel body. The user pushes the two push blocks to move closer to each other. The movement of the two push blocks closer to each other will drive the two positioning rods to move closer to each other, so that the two positioning rods are respectively separated from the positioning holes. At this time, the insert block will no longer be subject to blocking force, and the touch panel body can be taken out by moving it outward, which is convenient for disassembly of the touch panel body. Disassembly and installation are relatively convenient, and no professional tools are required, thereby facilitating repair or replacement of the touch panel body.

[0003] The elevator control panel in the prior art is fixed to the inner surface of the elevator car by fixing glue or screw fasteners. The maintenance and replacement method is cumbersome, and the screw threads may be damaged during the replacement process. Therefore, this article aims to propose an elevator display panel that is easy to disassemble and replace, does not require fasteners, is convenient for operators to quickly install, and is easy to quickly replace when it is damaged later.

DETAILED DESCRIPTION

[0016] The technical solution of the present application is further described below in conjunction with the accompanying drawings and embodiments.

[0017] like Figure 1-3 As shown, an elevator display panel that is easy to disassemble and replace includes a base 1 fixed in the elevator car, the base 1 is arranged in a C-shaped frame shape, and an inner cavity is arranged inside the upper plate section 101 and the lower plate section 102 of the base 1, and limiting components are arranged on both sides of the inner cavity. The limiting components include a limiting pull rod 2 movably inserted in the side wall of the inner cavity, and the head of the limiting pull rod 2 abuts on the outer wall of the base 1. A panel body 3 is arranged in the base 1, and the panel body 3 includes an integrally arranged functional plate section 301 and a connecting plate section 302, and a clamping shaft 303 is arranged on the connecting plate section 302. The free end of the limiting pull rod 2 located in the upper plate section 101 abuts on the lower surface of the clamping shaft 303, and the free end of the limiting pull rod 2 located in the lower plate section 102 abuts on the upper surface of the clamping shaft 303. A protruding section 4 is provided in the inner cavity, and the free end of the limiting pull rod 2 passes through the protruding section 4. A cavity 5 is provided in the protruding section 4, and a limiting sealing plate 6 is provided at the opening of the cavity 5. A boss 7 is provided on the limiting pull rod 2 located in the cavity 5, and a compression spring 8 is sleeved on the limiting pull rod 2 located between the boss 7 and the bottom of the cavity 5. One end of the compression spring 8 abuts against the bottom of the cavity 5, and the other end abuts against the surface of the boss 7 of the limiting pull rod 2, and the limiting boss 7 abuts against the inner surface of the limiting sealing plate 6. A hand-pull portion is provided at the free end of the limiting pull rod 2 located outside the base 1, and a rubber strip 9 is provided between the hand-pull portion and the base 1, and the rubber strip 9 is fixed to the outer surface of the base 1. The inner edge of the base 1 is provided with an anti-slip rubber strip 10 to prevent a gap from being generated when the panel body 3 is installed. The provision of the anti-slip rubber strip 10 prevents the hand-pull portion of the limit pull rod 2 from hitting the side of the base 1 due to the reset effect of the compression spring 8 when the limit pull rod 2 is loosened, thereby damaging the base 1. The base 1 is fixed in the elevator car by bolts.

[0018] When the operator installs the panel body 3, the upper end connecting plate section 302 of the panel body 3 is vertically plugged into the upper plate section 101 of the base 1, and the limiting pull rods 2 on both sides of the base 1 are pulled outward, so that the free ends of the limiting pull rods 2 located in the base 1 are contracted until the clamping shaft 303 on the connecting plate section 302 of the panel body 3 passes over the free end of the limiting pull rod 2. At this time, the limiting pull rod 2 is released. Due to the reset effect of the compression spring 8, the free end of the limiting pull rod 2 is abutted against the bottom of the corresponding clamping shaft 303, and the lower end connecting plate section 302 of the panel body 3 is fixed in the same way. If a situation inconvenient for clamping is encountered, the outer surface of the inner cavity of the lower plate section 102 of the base 1 can be set as a rotatable cover plate, so as to open the cover plate, and the connection and fixation between the lower end connecting plate section 302 of the panel body 3 and the lower end of the base 1 can be completed.

[0019] The present utility model is not limited to the above-mentioned embodiments. On the basis of the technical solution disclosed in the present utility model, technicians in this field can make some substitutions and deformations to some technical features therein according to the disclosed technical content without creative labor, and these substitutions and deformations are all within the protection scope of the present utility model.
