[0026] The roller structure 6 includes a clamping groove 601 symmetrically opened on the back side of the panel 3, and a clamping slider 602 is slidingly arranged inside the two clamping grooves 601. The ends of the two clamping sliders 602 that are away from each other are connected to the corresponding clamping groove 601 through a clamping spring 603, and the ends of the two clamping sliders 602 that are close to each other are provided with a roller frame 604, and the ends of the two roller frames 604 that are close to each other are rotatably provided with rollers 605.

[0027] It should be noted that: pressing down the sensing module squeezes the two rollers 605 on the top, driving the two clamping sliders 602 to slide away from each other along the clamping groove 601, and squeezing the clamping spring 603, and then pressing the sensing module inside the sensing module placement rack 4, the two clamping springs 603 release the pressure, control the two rollers 605 to approach each other, and limit the up and down displacement of the sensing module.

[0028] In the specific implementation process, refer to Figure 1 and Figure 3 As shown, the closing structure 2 includes a socket frame 201 symmetrically arranged on the front of the interior of the equipment box 1, and a sliding rod 202 is slidingly arranged inside the two socket frames 201. The front of the two sliding rods 202 is provided with a panel 3, and the back of the two sliding rods 202 is connected to the equipment box 1 through a closing spring 203.

[0029] It should be noted that: pulling the panel 3 and the two slide bars 202 slide along the two socket frames 201, so that the sensing module placement frame 4 is separated from the equipment box 1, making it convenient to pull up the sensing module for removal and press down the sensing module for installation.

[0030] In the specific implementation process, refer to Figure 2 As shown, a limit plate 5 is symmetrically provided on the back of the sensing module placement rack 4 .

[0031] It should be noted that the two limiting plates 5 limit the longitudinal displacement of the sensing module to avoid shaking of the sensing module during movement.

[0032] In the specific implementation process, refer to Figure 2 As shown, corner bars 7 are provided at the four corners of the back of the panel 3 , and the ends of the four corner bars 7 that are away from each other extend to the inner wall of the equipment box 1 .

[0033] It should be noted that the panel 3 is stably installed in the equipment box 1 by inserting the four corner bars 7 into the inner wall of the equipment box 1 .

[0034] In a specific implementation process, as shown in Reference 2 , two buckle grooves 8 are symmetrically provided on the back of the panel 3 .

[0035] It should be noted that: by symmetrically opening two buckle grooves 8 on the back side of the panel 3, the hand-holding area is increased to avoid the problem of slipping when removing.

[0036] In the specific implementation process, refer to Figure 1 and Figure 2 As shown, countersunk holes 10 are provided at the four corners of the front of the panel 3 , and connecting bolts 11 are placed inside the four countersunk holes 10 . The backs of the four connecting bolts 11 extend and are inserted into the corresponding threaded holes 9 on the front of the equipment box 1 .

[0037] It should be noted that the four countersunk holes 10 prevent the connecting bolts 11 from protruding from the panel 3 , thereby improving the aesthetics, and the four connecting bolts 11 are used to fix the panel 3 and the equipment box 1 .

[0038] The working principle of the elevator smart card reader provided by this utility model, which is easy to replace the sensing module, is as follows:

[0039] When in use, the panel 3 is pulled out, so that the two slide bars 202 slide along the two socket frames 201, so that the sensing module placement frame 4 is separated from the equipment box 1, which is convenient for pulling up the sensing module for removal and pressing down the sensing module for installation. Pressing down the sensing module squeezes the two rollers 605 on the top, drives the two clamping sliders 602 to slide away from each other along the clamping slide groove 601, and squeezes the clamping spring 603, and then presses the sensing module inside the sensing module placement frame 4. The two clamping springs 603 release the pressure, control the two rollers 605 to move closer to each other, and limit the up and down displacement of the sensing module. The two limit plates 5 limit the longitudinal displacement of the sensing module to avoid the problem of shaking of the sensing module during movement. The four connecting bolts 11 are passed through the four countersunk holes 10 and the threaded holes 9 to achieve the purpose of connecting the panel 3 and the equipment box 1.
