[0002] An elevator is a permanent transportation device that serves several specific floors in a building, with its car running on at least two rows of rigid rails that are perpendicular to the horizontal plane or have an inclination angle of less than 15° to the plumb line. There are also stepped types, with treads mounted on tracks and running continuously, commonly known as escalators or moving walkways, which are fixed lifting equipment that serve specified floors. A vertical elevator has a car that runs between at least two rows of rigid guide rails that are perpendicular or have an inclination angle of less than 15°. The size and structure of the car are convenient for passengers to enter and exit or load and unload goods. It is customary to use elevators as a general term for vertical transportation vehicles in buildings, regardless of their driving mode.

[0003] An elevator maintenance box is installed in the elevator. It is an important part of the elevator system. It is convenient for elevator maintenance and provides a certain space for maintenance personnel to perform inspection and debugging operations. The back panel of the elevator maintenance box is the basic structure that connects and supports various circuit boards and modules, and plays a fixing role.

[0023] See also Figure 1-5 The utility model provides a technical solution: a back plate for an elevator maintenance box, comprising a maintenance box body 1 and a maintenance device 3, the inner wall of the maintenance box body 1 is provided with a back plate body 2, and the maintenance device 3 is arranged on the back plate body 2.

[0024] The specific configuration and functions of the maintenance device 3 and the auxiliary component 34 will be described in detail below.

[0025] Specifically, the maintenance device 3 includes a hollow sleeve 31, and there are four hollow sleeves 31. Four groups of circular holes are opened on the surface of the back plate body 2. The four hollow sleeves 31 are rotatably connected to the inner walls of the four circular holes on the surface of the back plate body 2 respectively. Two clamping blocks 33 are fixedly connected to the inner wall of the hollow sleeve 31. Four connecting rods 35 are fixedly connected to the inner wall of the maintenance box body 1. The connecting rods 35 are sleeve-connected to the hollow sleeves 31, and two clamping grooves 37 are opened on the surface of the connecting rods 35.

[0026] In this embodiment: the hollow sleeve 31 in the back plate body 2 is sleeved on the connecting rod 35, and the block 33 is inserted into the slot 37 on the surface of the connecting rod 35. Then the hollow sleeve 31 is rotated, and the hollow sleeve 31 drives the block 33 to abut against the inner wall of the slot 37 on the surface of the connecting rod 35, so that it can be quickly installed and convenient for subsequent maintenance and disassembly.

[0027] Specifically, the card slot 37 includes a sliding groove and an arc groove. The sliding groove is for the card block 33 to be inserted and slide, and the arc groove is engaged with the card block 33. When the card block 33 is inserted into the card slot 37, the card block 33 can be first inserted into the sliding groove on the surface of the card slot 37, and then the hollow sleeve 31 is rotated. The hollow sleeve 31 drives the card block 33 to abut against the inner wall of the arc groove on the surface of the card slot 37, and the connection can be completed.

[0028] Specifically, a magnetic ring 1 36 is fixedly connected to the surface of the connecting rod 35, and a magnetic ring 2 38 is fixedly connected to the inner wall of one end of the hollow sleeve 31. The magnetic ring 1 36 is magnetically connected to the magnetic ring 2 38. When the hollow sleeve 31 contacts the magnetic ring 1 36, the magnetic ring 1 36 can be attracted to the magnetic ring 2 38, thereby positioning the hollow sleeve 31 and the block 33 to improve stability.

[0029] Specifically, one end of the hollow sleeve 31 extends out from the circular hole on the surface of the back plate body 2 , and the surface of the extended end of the hollow sleeve 31 is fixedly connected with the rotating member 32 .

[0030] In this embodiment, rotating the rotating member 32 can better control the rotation of the hollow sleeve 31 and improve the overall usability.

[0031] Specifically, an auxiliary component 34 is provided on the surface of the back panel body 2, and the auxiliary component 34 includes a guide rail block 341. There are four guide rail blocks 341, and the four guide rail blocks 341 are fixedly connected to the upper and lower inner walls of the maintenance box body 1 in pairs. Four slide grooves 343 are opened on the surface of the back panel body 2.

[0032] In this embodiment, when the back plate body 2 is assembled or disassembled, the guide block 341 can cooperate with the slide groove 343 on the surface of the back plate body 2 to stably slide the back plate body 2 out.

[0033] Specifically, two groups of rollers 344 are rotatably connected to the inner wall of the groove on the surface of the back plate body 2 .

[0034] In this embodiment, when the slide groove 343 slides on the guide rail block 341, the roller 344 can reduce friction and move better.

[0035] Specifically, a handle 342 is fixedly connected to one side surface of the back panel body 2 , and there are two handles 342 . The handles 342 can better help to take the back panel body 2 .

[0036] Working principle: When the equipment is in use, electrical components are installed on the back plate body 2, and the back plate body 2 is placed in the maintenance box 1. The maintenance device 3 and the auxiliary component 34 are set. When maintenance and disassembly are required, the rotating member 32 and the hollow sleeve 31 are rotated, and the hollow sleeve 31 drives the block 33 to rotate, and the block 33 loses the restraint on the arc groove on the surface of the slot 37. When the block 33 rotates to the sliding groove on the surface of the slot 37, the block 33 loses the restraint on the slot 37, and the back plate body 2 is pulled to one side by the handle 342. At this time, the roller 344 in the slide groove 343 is in By sliding on the guide block 341, the back panel body 2 can be stably pulled out for disassembly and replacement and maintenance can be carried out. By setting the maintenance device 3 and the auxiliary component 34, it is convenient to quickly take the back panel out of the maintenance box for maintenance, which can effectively reduce the back panel of the existing elevator maintenance box. Most of the back panels are fastened with screws, resulting in the need to use a screwdriver to unscrew the fastening screws one by one when the back panel needs to be disassembled for maintenance, resulting in troublesome operation. The screws need to be reassembled during subsequent installation, causing troublesome disassembly and assembly and inconvenient maintenance, thereby improving the overall usability of the equipment.
