[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] In one embodiment, such as Figures 1-5As shown, the elevator alarm device, which is easy to install and disassemble, includes an alarm module 120 installed inside the elevator car body 100. One side of the inner cavity of the elevator car body 100 is connected to the alarm module 120 via a locking assembly 200. A horn hole 121 is provided at the upper end of one side of the alarm module 120, and a camera 122 is provided below the horn hole 121 on one side of the alarm module 120. An alarm button 123 is provided below the camera 122 on one side of the alarm module 120. The locking assembly 200 includes a fixing seat 210 fixedly installed on the side wall of the inner cavity of the elevator car body 100. Slots 220 are provided at both the upper and lower ends of one side of the fixing seat 210, and a slot 220 is provided inside the fixing seat 210 to connect with the slot 220. The movable chamber is connected to a trapezoidal locking block 230, and a connecting post 240 is fixedly connected to the side of the trapezoidal locking block 230 away from the slot 220. A spring 250 is fixedly connected between the side of the trapezoidal locking block 230 away from the slot 220 and the movable chamber. The spring 250 is movably sleeved on the outer wall of the connecting post 240. An anti-touch component 300 is provided on one side of the fixed seat 210 outside the alarm module 120. An installation plate 270 is fixedly connected to one side of the alarm module 120. Insert blocks 280 matching the slot 220 are fixedly connected to the upper and lower ends of the side of the installation plate 270 away from the alarm module 120. The insert blocks 280 have slots 290 matching the trapezoidal locking block 230 on both sides.

[0028] In this embodiment, when the alarm module 120 needs to be installed, the insert 280 on one side of the mounting plate 270 is aligned with the slot 220 on the fixing base 210. Then, during the insertion of the insert 280, the two sets of trapezoidal locking blocks 230, which are initially in a fitted state, are pressed apart from the middle to both sides. The inclined surface of the trapezoidal locking blocks 230 is set as an arc-shaped inclined surface. When the two sets of trapezoidal locking blocks 230 slide into the corresponding movable chamber, the spring 250 is compressed and has elastic potential energy. When the insert 280 is fully inserted to the bottom of the inner cavity of the slot 220, the two sets of trapezoidal locking blocks 230 move and insert into the slots 290 on both sides of the insert 280 under the elastic potential energy of the spring 250, thus completing the installation of the insert 280. The installation and fixing of the 280 and alarm module 120 are as follows: When it is necessary to remove the alarm module 120, simply pull the pull plates 260 on both sides of the fixing base 210, which will cause the connecting column 240 and the trapezoidal locking block 230 to disengage from the locking slots 290 on both sides of the insert block 280, thereby releasing its fixing. Then, the staff can easily remove the alarm module 120. By setting the locking component 200, the alarm module 120 can be quickly connected and removed. The operation is simple and quick, which greatly improves the connection efficiency. At the same time, the cooperation between the insert block 280 and the trapezoidal locking block 230 can make the connection between the mounting plate 270 and the fixing base 210 stable and not easy to loosen, effectively ensuring the stability of the installation of the alarm module 120.

[0029] In one embodiment, such as Figure 5As shown, the ends of the two sets of connecting columns 240 located on the same side that are away from the trapezoidal block 230 extend through to the outside of the fixed base 210 and are fixedly connected to the same pull plate 260. By setting the pull plate 260, the staff can simultaneously control the two sets of connecting columns 240 and the trapezoidal block 230 located on the same side of the fixed base 210, which further improves the efficiency of the staff in disassembling and assembling the alarm module 120.

[0030] In one embodiment, such as Figure 2 and Figure 3 As shown, the anti-touch assembly 300 includes fixed boxes 310 fixedly installed at both ends of one side of the fixed base 210. Each of the two fixed boxes 310 has a horizontally arranged sliding rod 320. A slider 330 is slidably sleeved on the outer wall of each of the two sliding rods 320. One end of each slider 330 is fixedly connected to the same anti-touch plate 340. Positive magnetic blocks 350 are fixedly installed on both sides of each slider 330. Negative magnetic blocks 360 are fixedly installed at the upper and lower ends of the inner cavity of the fixed box 310. The initial position of the anti-touch plate 340 is directly above the alarm button 123 to prevent passengers inside the elevator car from accidentally touching it during operation. Be careful not to accidentally touch the alarm button 123, which could cause a false alarm and panic among passengers inside the elevator car 100. The attraction between the opposite poles of the positive and negative magnetic blocks 350 and 360 serves to fix and limit the slider 330 and the anti-touch plate 340, requiring an upward pushing force to move the anti-touch plate 340. When the alarm module 120 needs to be disassembled or reassembled, simply push the anti-touch plate 340 along the slide bar 320 to the top of the fixing box 310, and fix it with the positive and negative magnetic blocks 350 and 360 to complete the subsequent disassembly and reassembly of the alarm module 120.

[0031] In one embodiment, such as Figure 1 As shown, handrails 110 are fixedly connected to both sides of the inner cavity of the elevator car body 100; by setting handrails 110, support points can be provided for passengers, improving their comfort.

[0032] The above embodiments disclose an elevator alarm device that is easy to install and disassemble. When the alarm module 120 needs to be installed, the insert 280 on one side of the mounting plate 270 is aligned with the slot 220 on the fixing base 210. Then, during the insertion of the insert 280, the two sets of trapezoidal locking blocks 230, initially in a fitted state, are pressed apart from the middle to both sides. The inclined surfaces of the trapezoidal locking blocks 230 are set as arc-shaped inclined surfaces. When the two sets of trapezoidal locking blocks 230 slide into the corresponding movable chambers, the spring 250 is compressed and possesses elastic potential energy. When the insert 280 is fully inserted to the bottom of the inner cavity of the slot 220, the two sets of trapezoidal locking blocks... Under the elastic potential energy of the spring 250, the locking block 230 moves and inserts into the slots 290 on both sides of the plug 280, completing the installation and fixing of the plug 280 and the alarm module 120. When it is necessary to remove the alarm module 120, simply pull the pull plates 260 on both sides of the fixing base 210 to drive the connecting post 240 and the trapezoidal locking block 230 out of the slots 290 on both sides of the plug 280 to release its fixation. Then, the staff can easily remove the alarm module 120. By setting the locking component 200, the alarm module 120 can be quickly connected and removed. The operation is simple and quick, greatly improving the connection efficiency.

[0033] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
