However, regardless of the installation method, the connection of the connectors and fasteners is required. Since the two are between the time attendance machine and the wall, they are difficult to observe directly during installation and calibration, which affects the installation efficiency and effectiveness. Therefore, it is necessary to develop a magnetic time attendance device with a quick docking and fixing mechanical structure to solve the shortcomings of the existing technology. Utility Model Content

[0007] Preferably, the positioning component includes a fixing plate installed in the mounting groove and fixedly connected to the front of the mounting frame. A permanent magnet and a snap-fit ​​block are provided on the side of the fixing plate away from the center of the mounting groove. The permanent magnet is fixedly installed on the fixing plate. A slider is slidably snapped onto the side of the permanent magnet away from the card reader. The slider is fixedly connected to the back of the snap-fit ​​block.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 5 As shown, this utility model provides a magnetic attendance device with a quick docking and fixing mechanical structure, including a time clock 1. The back of the time clock 1 has two mounting slots, left and right. The mounting slots are equipped with a card-mounting component. The mounting slots are also equipped with a mounting bracket 2 located on the back of the card-mounting component. The mounting bracket 2 is fitted with mounting bolts 3. The mounting bracket 2 is mounted to the wall by the mounting bolts 3. The back of the card-mounting component is connected to the mounting bracket 2. The upper and lower ends of the card-mounting component are connected to the upper and lower ends of the inner cavity of the mounting slot.

[0025] The mounting assembly consists of two positioning components 4, a snap-fit ​​component 6, and an adjustment component 5 connected between the two positioning components 4. The back of the two positioning components 4 is fixedly connected to the upper and lower ends of the front of the mounting frame 2. The upper and lower ends of the adjustment component 5 are connected to the two positioning components 4. The distal ends of the two snap-fit ​​components 6 are fixedly connected to the upper and lower ends of the inner cavity of the mounting slot, respectively. The proximal ends of the two snap-fit ​​components 6 abut against the distal ends of the two positioning components 4. Due to the positioning components 4, with the cooperation of the mounting frame 2 and the mounting slot, the card reader 1 can snap-fit ​​with the positioning components 4 on the mounting frame 2 through the snap-fit ​​component 6, thereby making it easy for the card reader 1 to quickly complete the installation work through the mounting frame 2 and the snap-fit ​​assembly.

[0026] The positioning component 4 includes a fixing plate 41 installed in the mounting groove and fixedly connected to the front of the mounting frame 2. A permanent magnet 42 and a snap-fit ​​block 43 are provided on the side of the fixing plate 41 away from the center of the mounting groove. The permanent magnet 42 is fixedly installed on the fixing plate 41. A slider 44 is slidably snapped onto the side of the permanent magnet 42 away from the card reader 1. The slider 44 is fixedly connected to the back of the snap-fit ​​block 43. Due to the setting of the permanent magnet 42, under its adsorption force, the length of the snap-fit ​​component 6 can be increased, and the telescopic sleeve 61 can be snapped between the mounting frame 2 and the snap-fit ​​block 43, ensuring that the card reader 1 can be quickly and firmly installed on the wall through the mounting frame 2.

[0027] The back of the snap-fit ​​block 43 above the permanent magnet 42 is a smooth slope, the front of the snap-fit ​​block 43 above the permanent magnet 42 is a smooth slope, and the upper cross-section of the snap-fit ​​block 43 is conical.

[0028] The adjustment component 5 includes an adjustment sleeve 51 disposed between the mounting groove and the two fixed plates 41. A linkage rod 52 is fixedly sleeved inside the adjustment sleeve 51. The upper and lower ends of the linkage rod 52 pass through the two fixed plates 41 respectively and are rotatably sleeved inside the fixed plates 41. Due to the rotation of the linkage rod 52, with the cooperation of the upper and lower fixed plates 41, rotating the adjustment sleeve 51 can simultaneously drive the two pressure plates 53 to move relative to each other. Thus, under the restriction of the permanent magnet 42 and the locking block 43, the initial support strength of the positioning spring 54 on the locking block 43 can be quickly adjusted.

[0029] Both ends of the linkage rod 52 are threaded with a pressure plate 53 that slides and engages with the front of the permanent magnet 42. The side of the pressure plate 53 away from the fixed plate 41 is abutted and connected to a positioning spring 54. The other end of the positioning spring 54 is abutted and connected to the side of the snap block 43 near the fixed plate 41. Due to the setting of the adjustment component 5, under the restriction of the positioning component 4, the elastic support strength of the positioning component 4 can be changed by adjusting the adjustment component 5, thereby enabling the snap block 6 to overcome the resistance of the positioning component 4 and change the force for removal, thus facilitating a firm installation, easy disassembly, and a certain impact buffering capacity.

[0030] The snap-fit ​​assembly 6 includes a telescopic sleeve 61 that is attracted to the end of the permanent magnet 42 away from the fixed plate 41. The surfaces of the telescopic sleeve 61 and the snap-fit ​​block 43 are parallel and smooth inclined surfaces. A sliding cavity 62 is provided at the end of the telescopic sleeve 61 away from the permanent magnet 42. A connecting block 63 is slidably snapped into the inside of the sliding cavity 62. The other end of the connecting block 63 passes through the sliding cavity 62 and is fixedly connected to the inner wall of the mounting groove.

[0031] A return spring 64 is installed inside the sliding cavity 62. The two ends of the return spring 64 are respectively connected to the inner cavity of the sliding cavity 62 and the end of the connecting block 63 near the permanent magnet 42. The elastic force of the return spring 64 is greater than the weight of the telescopic sleeve 61 and less than the magnetic attraction force of the permanent magnet 42. Due to the setting of the return spring 64, under the restriction of the sliding cavity 62, the elastic restoring force of the return spring 64 can automatically pull the telescopic sleeve 61, so that the overall length of the telescopic sleeve 61 and the connecting block 63 is minimized. This allows the snap-fit ​​assembly 6 to pass smoothly through the snap-fit ​​block 43 and move to the axial direction of the permanent magnet 42 during installation. Then, under the magnetic attraction force of the permanent magnet 42, the telescopic sleeve 61 can be attracted, increasing the overall length of the snap-fit ​​assembly 6. At the same time, the telescopic sleeve 61 is snapped between the mounting frame 2 and the snap-fit ​​block 43, thereby completing the quick connection between the card reader 1 and the mounting frame 2.

[0032] The card reader 1 has a sealing ring 7 on the back edge, and the outer surface of the sealing ring 7 is smoothly connected to the outer surface of the card reader 1. The card reader 1 also has a display screen 8, a control panel 9 and a fingerprint reader 10 on the front.

[0033] Working principle and usage process of this utility model:

[0034] First, adjust the initial elastic strength of the positioning spring 54 according to environmental factors, so that after installation, the force required to push the locking block 43 to further compress the positioning spring 54 under the tension strength is achieved. Specifically, rotate the adjusting sleeve 51 so that under the restriction of the permanent magnet 42, it drives the two pressure plates 53 to move relative to each other through the linkage rod 52. Under the restriction of the locking block 43 by the permanent magnet 42 and the slider 44, the upper end of the positioning spring 54 remains stationary while the lower end moves up and down, thereby changing the initial elastic strength of the positioning spring 54.

[0035] Then, the mounting bracket 2 is installed on the wall using the mounting bolts 3. Then, the two mounting slots on the back of the card reader 1 are aligned with the two mounting bolts 3 and the snap-fit ​​components on the front, so that the positioning component 4 and the snap-fit ​​component 6 can move closer to each other. As the mounting bracket 2 continues to go deeper into the mounting slot, the positioning component 4 and the snap-fit ​​component 6 can move closer to each other. When the telescopic sleeve 61 passes the snap-fit ​​block 43, under the magnetic attraction of the permanent magnet 42, it slowly moves closer to and presses against the top of the permanent magnet 42 between the snap-fit ​​block 43 and the mounting bracket 2.

[0036] Thus, the time clock 1 and the two mounting brackets 2 are firmly connected together, and with the cooperation of the sealing ring 7, the time clock 1 is tightly attached to the wall. Finally, daily attendance can be completed through the display screen 8, the control panel 9 and the fingerprint reader 10.
