DETAILED DESCRIPTION

[0022] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0023] As described in the background technology, in order to facilitate regular debugging and maintenance of the device, this embodiment provides an embedded elevator call box, which can achieve the effect of rapid disassembly and assembly without damaging the box cover, which is beneficial to the debugging and maintenance of the device.

[0024] See also Figures 1 to 6This embodiment proposes an embedded elevator call box, including a call box body 1, a box cover 2 is provided on the outside of the call box body 1, and a clamping mechanism 3 is provided between the call box body 1 and the box cover 2.

[0025] The call box body 1 and the box cover 2 are connected by a snap-fit ​​mechanism 3. The device can realize quick disassembly and assembly between the call box body 1 and the box cover 2 by pressing, which optimizes the disassembly and assembly process. No additional tools are required during the disassembly and assembly process, and damage to the outer surface of the box cover 2 during the disassembly and assembly process is effectively avoided, which is conducive to regular debugging and maintenance of the device.

[0026] The clamping mechanism 3 includes two clamping grooves 301 opened on the outer surface of the calling box body 1, and the inner wall of the box cover 2 is provided with two slide grooves 302. The inner wall of each slide groove 302 is slidably sleeved with a clamping block 303, and the clamping block 303 can slide in the inner wall of the slide groove 302.

[0027] The other ends of the two clamping blocks 303 are slidably connected to the inner walls of the two clamping slots 301 , respectively, and the size of the corners of the clamping blocks 303 matches the size of the corners of the clamping slots 301 .

[0028] By limiting the relationship between the card slot 301 and the card block 303 , the device can be made more stable during installation and avoid falling off.

[0029] The inner wall of each slide groove 302 is fixedly connected to two limit rods 307, and the two sides of the two clamping blocks 303 are respectively slidably mounted on the outer surfaces of the four limit rods 307. By setting the limit rods 307, the clamping blocks 303 can be more stable during the movement, which facilitates the stable and rapid disassembly and assembly of the box cover 2 on the calling box body 1.

[0030] Two telescopic springs 304 are fixedly connected to the outer surface of each clamping block 303 , and the other ends of the four telescopic springs 304 are fixedly connected to the inner walls of the two slide grooves 302 , respectively. The clamping block 303 can be reset by providing the telescopic springs 304 .

[0031] A pressing rod 305 is fixedly connected to the other side of each clamping block 303 , and the two pressing rods 305 are slidably sleeved in the inner walls of the two sliding grooves 302 .

[0032] When the block 303 is moved by pressing the pressing rod 305, the two corresponding telescopic springs 304 can be compressed. When the telescopic springs 304 are compressed, they will deform and generate elastic force. At this time, if the pressed pressing rod 305 is released, the block 303 can rebound and reset with the help of the elastic force of the two corresponding telescopic springs 304.

[0033] The ends of the two pressing rods 305 that are away from each other are fixedly connected with handles 306, and the outer surfaces of the two handles 306 are coated with an anti-slip layer. By providing the handles 306, the contact area of ​​the pressing rods 305 can be increased, so that the staff can press the pressing rods 305 more conveniently, thereby facilitating the rapid disassembly and assembly of the box cover 2.

[0034] An integrated circuit board 4 is installed on the inner wall of the call box body 1. The integrated circuit board 4 is an existing mechanism. The integrated circuit board 4 can connect the device to a reserved external line to facilitate the control of the adapted elevator.

[0035] A wire hole 5 is provided on the back of the call box body 1, and the wire hole 5 is connected to the inside of the call box body 1. By arranging the integrated circuit board 4 and the wire hole 5, the device can be embedded in a suitable position, which is convenient for connecting with the reserved line, which is beneficial to controlling the elevator through the device.

[0036] The outer surface of the call box body 1 is provided with two symmetrical reserved grooves 8, and the inner wall of each reserved groove 8 is fixedly connected with a magnetic sleeve 9. The back of the box cover 2 is fixedly connected with two symmetrical magnetic blocks 10 and a sealing ring 11, and the two magnetic blocks 10 are respectively adapted to the two magnetic sleeves 9.

[0037] By setting the reserved groove 8, the magnetic sleeve 9 and the magnetic block 10 to cooperate with each other, when the box cover 2 is installed, the two magnetic blocks 10 can be respectively adsorbed in the two magnetic sleeves 9 by means of the magnetic effect of the magnetic sleeve 9 and the magnetic block 10.

[0038] In this way, both sides of the box cover 2 can be more stably installed on the outer surface of the calling box body 1, thereby improving the fit between the calling box body 1 and the box cover 2, reducing the gap, and making the appearance of the device more beautiful.

[0039] By providing the sealing ring 11 , the sealing performance between the calling box body 1 and the box cover 2 can be improved, and the probability of dust entering the calling box body 1 can be reduced.

[0040] When the box cover 2 needs to be removed from the calling box body 1, it can be achieved by pressing the two handles 306. When the two handles 306 are pressed, the two pressing rods 305 can be used to move the two blocks 303 closer to each other, and at the same time compress the corresponding telescopic springs 304, so that the two blocks 303 can be moved out from the corners of the corresponding slots 301 respectively.

[0041] The limiting effect on the box cover 2 is released, and then the staff can directly remove the box cover 2 from the calling box body 1, which simplifies the disassembly and assembly process and facilitates the debugging or maintenance of the components inside the calling box body 1.

[0042] The outer surface of the box cover 2 is provided with a display screen 6 and a button 7, which are electrically connected to the integrated circuit board 4 through wires. By providing the display screen 6 and the button 7, the device can be conveniently used to control the adapted elevator.

[0043] Working principle: when in use, the integrated circuit board 4 can be connected to the reserved circuit through the wire hole 5, and then the call box body 1 can be embedded as a whole in a suitable position for fixed installation. When it is necessary to debug or maintain the components inside the call box body 1, the two handles 306 can be pressed to achieve the effect of quickly disassembling the box cover 2. When the two handles 306 are pressed, the two pressing rods 305 can be used to make the two clamping blocks 303 move closer to each other, so that the two clamping blocks 303 will respectively squeeze the corresponding two telescopic springs 304, and at the same time, the two clamping blocks 303 will respectively move out from the corners of the corresponding card slots 301, so as to achieve the effect of releasing the limit work on the box cover 2. Then the staff can directly remove the box cover 2 from the call box body 1, and then debug or maintain the components inside the call box body 1. After completing the above work, the two handles 306 can be pressed and the box cover 2 can be limited and installed on the call box body 1. At this time The two handles 306 are pressed to make the two card blocks 303 move towards each other. When the two card blocks 303 can no longer move towards each other, the box cover 2 can be covered on the calling box body 1, and the two card blocks 303 are respectively located in the two card slots 301. The two magnetic blocks 10 on the other side will be respectively adsorbed in the two magnetic suction sleeves 9. Then, after the magnetic suction block 10 is fully inserted into the corresponding magnetic suction sleeves 9, the two pressed handles 306 can be released. At this time, the two card blocks 303 will be reset by the elastic force generated by the compression of the two telescopic springs 304. In this way, the two card blocks 303 will move away from each other, so that the two card blocks 303 are respectively stuck in the corners of the corresponding card slots 301, realizing the limiting work of the box cover 2, and completing the quick installation work of the box cover 2. Through the above description, the disassembly and assembly of the box cover 2 does not require the use of additional tools, which optimizes the disassembly and assembly process, and frequent disassembly and assembly will not cause damage to the outer surface of the box cover 2, which is more practical.
