[0004] To improve security, this application provides an access control system for university dormitory management.

[0005] This application provides a technical solution for an access control system used in university dormitories:

[0006] A university dormitory access control system includes a device body. The device body has two symmetrical T-shaped support slots inside. Two symmetrical support plates are fixedly connected to the inner walls of the T-shaped support slots. A locking block is rotatably connected inside the right support plate. The side of the locking block closest to the support plate passes through the support plate and is fixedly connected to a bidirectional threaded rod. The side of the bidirectional threaded rod furthest from the support plate is rotatably connected to the inside of the T-shaped support slot. A sliding rod is fixedly connected between the surface of the left support plate and the inner wall of the T-shaped support slot. Two symmetrical sliders are threadedly connected to the surface of the bidirectional threaded rod. The internal threads of each slider match the threads at both ends of the bidirectional threaded rod. Two symmetrical sliders are also slidably connected to the surface of the slider rod. The four sliders are grouped into two horizontal groups. U-shaped blocks are fixedly connected to the upper surfaces of both groups of sliders. A face recognition device is slidably connected to the inner wall of the T-shaped support groove. A T-shaped block is fixedly connected to the lower surface of the face recognition device. The surface of the T-shaped block is inserted into the surface of the U-shaped block. Two symmetrical keyholes are opened inside the device body. Keys are slidably connected to the inner walls of both keyholes, and the interior of the keys is inserted into the surface of the blocks.

[0007] By adopting the above technical solution and setting up U-shaped clips, the face display can be clamped and fixed, and can only be disassembled with a key, which greatly ensures the safety of the display screen.

[0008] Preferably, the display screen of the face recognition device is provided with two symmetrical U-shaped protective clamps. Three support blocks are fixedly connected to the opposite surfaces of the two U-shaped protective clamps. A second limiting groove is opened inside each of the three support blocks. A shock-absorbing block is slidably connected to the inner wall of the second limiting groove. A protective shell is fixedly connected to the side of the three shock-absorbing blocks away from the second limiting groove.

[0009] By adopting the above technical solution and fixing the protective clamp with shock-absorbing blocks, the screen surface of the face recognition device can be protected to prevent students from accidentally touching it and causing scratches, while also avoiding damage to the face recognition device.

[0010] Preferably, a second spring is fixedly connected between the interior of the second limiting groove and the surface of the shock absorber.

[0011] By adopting the above technical solution, the second spring can buffer the shock absorber block and improve the protective performance of the device.

[0012] Preferably, the U-shaped protective clamp on the left side has two symmetrical first limiting grooves inside, one side of which passes through the U-shaped protective clamp and communicates with the outside.

[0013] By adopting the above technical solution and setting a limiting groove, the movement of the protective plate can be limited.

[0014] Preferably, the inner walls of both first limiting grooves are slidably connected with limiting rods, and the end of the limiting rod away from the first limiting groove is fixedly connected to the surface of the right-side U-shaped protective clamp.

[0015] By adopting the above technical solution, the stability of the stretching can be ensured by connecting the limiting rod, thereby ensuring that the clamp can clamp the screen more accurately.

[0016] Preferably, a first spring is movably sleeved on the surface of the limiting rod, and the two ends of the first spring are fixedly connected to the inner wall of the first limiting groove and the surface of the limiting rod, respectively.

[0017] By adopting the above technical solution and setting a first spring, the clamp can be reset, thereby fixing the clamp to the screen for protection.

[0018] Preferably, the inner walls of both U-shaped protective clamps are fixedly connected with protective rubber pads, and the interiors of both U-shaped protective clamps are fixedly connected with protective glass.

[0019] By adopting the above technical solutions and by setting rubber pads and protective glass, the overall protective performance of the protective device can be improved, making the device more practical.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. Using a key to control the threaded rod further achieves clamping and contact fixation of the face recognition device. The threaded rod and sliding rod make the clamping more stable, ensuring the stability of the device. At the same time, only one keyhole is set to control the disassembly and assembly of the face recognition device, which greatly improves the security of the device and its own protective performance.

[0022] 2. By setting up protective clamps, which can be freely assembled and disassembled, and by using protective glass to protect the screen, the service life of the screen is greatly improved.

[0031] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0032] This application discloses an access control system for university dormitory management.

[0033] Reference Figures 1-5 A university dormitory access control system includes a device body 1. The device body 1 has two symmetrical T-shaped support grooves 15 inside. Two symmetrical support plates 11 are fixedly connected to the inner walls of the T-shaped support grooves 15. A transmission-type locking block 10 is rotatably connected inside the right support plate 11. The side of the locking block 10 closest to the support plate 11 passes through the support plate 11 and is fixedly connected to a bidirectional threaded rod 12 for transmitting rotation. The side of the bidirectional threaded rod 12 furthest from the support plate 11 is rotatably connected inside the T-shaped support groove 15. The surface of the left support plate 11 is flush with the T-shaped support groove. A sliding rod 8, symmetrical to the bidirectional threaded rod 12, is fixedly connected between the inner walls of the support groove 15 for limiting sliding. Two symmetrical sliders 13 are threadedly connected to the surface of the bidirectional threaded rod 12. Two symmetrical sliders 13 are also slidably connected to the surface of the sliding rod 8 for movement. The four sliders 13 are grouped into two horizontal groups. U-shaped locking blocks 14 for limiting engagement are fixedly connected to the upper surfaces of both groups of sliders 13. A face recognition device 3 is slidably connected to the surface of the T-shaped support groove 15. The face recognition device 3 is an existing structure of CN216647448U, which will not be described in detail here.

[0034] The lower surface of the face recognition device 3 is fixedly connected to a T-shaped locking block 16 for limiting engagement. The surface of the T-shaped locking block 16 is inserted into the surface of the U-shaped locking block 14. By moving and clamping the U-shaped locking block 14, the face recognition device 3 can be fixed. The inside of the device body 1 has two symmetrical keyholes 2 for limiting engagement. The inner walls of the two keyholes 2 are slidably connected to keys 9 for releasing engagement. The inside of the key 9 is inserted into the surface of the locking block 10. When the staff needs to remove the face recognition device 3 for maintenance and inspection, they first insert the key 9 into the keyhole 2 to complete the engagement of the key 9 with the locking block 10. Turning the key 9 causes the locking block 10 to rotate, which in turn drives the bidirectional threaded rod 12 to rotate. Further control the two sliders 13 to move in opposite directions, further driving the two U-shaped blocks 14 to move in opposite directions, releasing the insertion relationship with the surface of the T-shaped block 16, releasing the fixation of the face recognition device 3, and taking out the face recognition device 3 for inspection and maintenance. When it is necessary to put the face recognition device 3 into the T-shaped support groove 15 for fixation, turn the key 9 in the opposite direction, further driving the threaded rod to rotate in the opposite direction through the block 10, further driving the two sliders 13 to move towards the same side, further driving the two U-shaped blocks 14 to clamp and limit the T-shaped block 16, completing the fixation of the face recognition device 3. This fixing method is both stable and safe, greatly enhancing the security effect of the access control.

[0035] The face recognition device 3 has two symmetrical U-shaped protective clamps 6 for clamping on its display screen. Three support blocks 17 are fixedly connected to the opposite sides of the two U-shaped protective clamps 6. The interior of each of the three support blocks 17 is provided with a second limiting groove 22 for limiting sliding. A shock-absorbing block 7 for buffering and shock absorption is slidably connected to the inner wall of the second limiting groove 22. A protective shell 5 for protection is fixedly connected to the surface of the shock-absorbing block 7 away from the second limiting groove 22. The protective shell 5 can cover the two sides and four corners of the face recognition device 3 screen to provide efficient protection for the screen. A second spring 21 for resetting is fixedly connected between the interior of the second limiting groove 22 and the surface of the shock-absorbing block 7.

[0036] The left U-shaped protective clamp 6 has two symmetrical first limiting grooves 20 for limiting sliding. One side of the first limiting groove 20 passes through the U-shaped protective clamp 6 and communicates with the outside. The inner walls of the two first limiting grooves 20 are slidably connected to limiting rods 19 for limiting movement. The end of the limiting rod 19 away from the first limiting groove 20 is fixedly connected to the surface of the right U-shaped protective clamp 6. The surface of the limiting rod 19 is movably sleeved with a first spring 18 for resetting. The two ends of the first spring 18 are fixedly connected to the inner wall of the first limiting groove 20 and the surface of the limiting rod 19, respectively. The inner surfaces of the two U-shaped protective clamps 6 are fixedly connected to protective rubber pads 23 for protection. The interiors of the two U-shaped protective clamps 6 are fixedly connected to protective glass 4 for protective screens. When it is necessary to disassemble the protective shell 5, the worker pulls the two protective shells 5 to both sides with both hands, which further drives the shock absorber 7 to move to both sides. This further drives the support block 17 to move to both sides, and further drives the two U-shaped protective clamps 6 to move to both sides. Due to the limiting effect of the limiting rod 19, the two U-shaped protective clamps 6 can open smoothly to both sides, and the protective shell 5 can be removed for cleaning and maintenance. When it is necessary to install the protective shell 5 to protect the screen of the face recognition device 3, the staff pulls the two protective shells 5 again, and then drives the two U-shaped protective clamps 6 to move to both sides through the two shock-absorbing blocks 7. The two U-shaped protective clamps 6 are placed on both sides of the screen, aligned with the clamping groove in the middle of the U-shaped protective clamps 6, and then the hands are released. Under the action of the first spring 18 on both sides, the two U-shaped protective clamps 6 are reset and clamped. The protective rubber pads 23 on both sides can ensure that the sides of the screen are not damaged during the clamping process. At the same time, the two protective glass 4 can provide positioning during the clamping process while protecting the screen, making clamping more convenient.

[0037] The implementation principle of an access control system for university dormitory management in this embodiment is as follows: When staff need to remove the face recognition device 3 for maintenance and inspection, they first insert the key 9 into the keyhole 2, further completing the insertion of the key 9 and the card block 10. Turning the key 9 causes the card block 10 to rotate, which in turn causes the bidirectional threaded rod 12 to rotate, further controlling the two sliders 13 to move in opposite directions, further causing the two U-shaped cards 14 to move in opposite directions, releasing the insertion relationship with the surface of the T-shaped card block 16, further releasing the fixation of the face recognition device 3, and allowing the face recognition device 3 to be removed for inspection and maintenance. When it is necessary to place the face recognition device 3 into the T-shaped support groove 15 for fixation, the key 9 is turned in the opposite direction, further causing the threaded rod to rotate in the opposite direction through the card block 10, further causing the two sliders 13 to move towards the same side, further causing the two U-shaped cards 14 to move towards the T-shaped support groove 15. The clamping block 16 clamps and limits the face recognition device 3, thus fixing it in place. When the protective shell 5 needs to be disassembled, the staff pulls the two protective shells 5 to the sides with both hands, which further moves the shock-absorbing block 7 to the sides, the support block 17 to the sides, and the two U-shaped protective clamps 6 to the sides. Due to the limiting action of the limiting rod 19, the two U-shaped protective clamps 6 can be opened smoothly to the sides. The protective shell 5 can be removed for cleaning and maintenance. When the protective shell 5 needs to be installed to protect the screen of the face recognition device 3, the staff pulls the two protective shells 5 again, which in turn moves the two U-shaped protective clamps 6 to the sides through the two shock-absorbing blocks 7. The two U-shaped protective clamps 6 are placed on both sides of the screen, aligned with the clamping groove in the middle of the U-shaped protective clamps 6, and then the staff releases their hands. Under the action of the first spring 18 on both sides, the two U-shaped protective clamps 6 return to their original position, thus achieving clamping.

[0038] The above are merely optional embodiments of this disclosure and are not intended to limit this disclosure. Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
