Technical Field

[0001] This utility model belongs to the field of access control terminal technology, specifically relating to a dedicated access control terminal device for prison cells. Background Technology

[0002] The dedicated access control terminal for prison cells is the core equipment of the intelligent prison cell management system. It integrates various biometric technologies and IoT functions, primarily used to improve prison security and management efficiency. It supports multiple authentication methods, including facial recognition, fingerprint recognition, and IC card recognition. As a central controller, it can uniformly manage access control, lighting, and other equipment, supporting remote control or control upon request. A utility model patent with patent authorization announcement number CN210864859U discloses an access control terminal, which mainly includes an outer frame, a display screen, an assembly shell, a detection shell, a lock body, a control motherboard and a keypad. The display screen is embedded in the upper front part of the outer frame, the assembly shell is fixedly installed in the middle front part of the outer frame, a middle sleeve is installed through the inner side of the assembly shell, and a rubber pad is fixedly installed inside the middle sleeve.

[0003] However, existing cell-specific access control terminal devices also have certain defects. Most existing cell-specific access control terminal devices simply adopt the setting of slotted structures such as heat dissipation slots and flow slots to complete the heat dissipation treatment of electrical components inside the access control terminal housing. Due to the weak efficiency of natural ventilation, it is easy to cause the problem of untimely heat dissipation. Summary of the Invention

[0004] The purpose of this utility model is to provide a dedicated access control terminal device for prison cells, which solves the problem that existing dedicated access control terminal devices for prison cells often simply use slotted structures such as heat dissipation grooves and flow grooves to complete the heat dissipation treatment of electrical components inside the access control terminal housing. However, due to the weak efficiency of natural ventilation, heat dissipation is easily delayed.

[0005] To achieve the above objectives, this utility model provides a dedicated access control terminal device for prison cells, comprising a panel, a housing fixedly connected to the back of the panel, multiple evenly distributed heat dissipation grooves on both sides of the housing, two symmetrically distributed mounting ears fixedly connected to both sides of the panel, a display screen on the surface of the panel, a camera on the surface of the panel and above the display screen, a heat dissipation mechanism on the housing, a wire-passing hole on the surface of the housing, a fixing rod fixedly connected to the back of the housing, a connecting piece rotatably sleeved on the outer side of the fixing rod, an iron plate fixedly connected to the front of the connecting piece, the iron plate slidably connected to the housing, the iron plate covering the outer side of the wire-passing hole, and a permanent magnet fixedly connected to the back of the housing, the permanent magnet being magnetically connected to the iron plate.

[0006] The principle of this utility model is as follows: By setting the mounting ears, the access control terminal can be installed and used in conjunction with bolts and other fasteners. Under the magnetic attraction of the first permanent magnet, the iron plate can be kept in a stable and close fit, protecting the unused cable passage hole and preventing the intrusion of foreign objects. When it is necessary to pass the cable, the iron plate can be pushed to deflect, causing the iron plate to detach from the first permanent magnet and drive the connecting plate to rotate along the surface of the fixed rod, so that the connecting plate slides along the surface of the limit plate to ensure the rotation stability of the connecting plate. Finally, the connecting plate drives the iron plate to contact the second permanent magnet. Under the magnetic attraction, the iron plate can be kept stable, thereby exposing the cable passage hole. Under the action of the cable passage hole and the protective ring, the cable can be passed through. The use of a silent fan and heat dissipation duct provides ventilation for the electrical components inside the housing, ensuring good heat dissipation efficiency. The filter screen removes dust and other impurities from the air, preventing them from affecting subsequent electrical components. Pulling the end cover upwards moves the traction line and the filter screen upwards, causing the elastic frame to move and the spring to deform. When the elastic frame contacts the limiting plate, the end cover can be released to allow the spring to return to its original shape, pushing the filter screen downwards. This causes the elastic frame to contact and impact the contact plate, resulting in the filter screen vibrating and removing dust, ensuring the filter screen's flowability.

[0007] The beneficial effects of this utility model are as follows: This solution utilizes the magnetic attraction of the first permanent magnet to ensure the iron sheet is in a stable, close fit, sealing unused wire holes and preventing the intrusion of debris. The second permanent magnet, connecting piece, and other structures allow the iron sheet to be deflected and opened. The wire holes facilitate the passage of cables used in access control terminals. The protective ring protects the cables, preventing damage to their sheaths. The silent fan and heat dissipation trough provide forced heat dissipation for internal electronic components, ensuring efficient cooling. The filter removes dust and other particulate impurities from the air. Furthermore, the traction wire, spring, and contact piece allow the elastic frame to vibrate the filter, cleaning impurities and preventing filter clogging.

[0008] Furthermore, a protective ring is fixedly connected to the inner wall of the wire passage hole. The inner side of the protective ring is rounded. The protective ring is made of silicone. The protective ring can be used to pass through and protect cables, etc., and the silicone material has good flexibility.

[0009] Furthermore, two evenly distributed limiting discs are fixedly sleeved on the outer side of the fixing rod. Each limiting disc is slidably connected to the connecting piece. By setting the limiting discs, the connecting piece can be deflected and limited, thus preventing the connecting piece from detaching.

[0010] Furthermore, a second permanent magnet is fixedly connected to the back of the housing and to the upper right side of the iron sheet. Multiple second permanent magnets are provided and evenly distributed on the housing. The iron sheet can be magnetically fixed by the second permanent magnet.

[0011] Furthermore, the heat dissipation mechanism includes a silent fan, which is installed inside the housing. A protective cover is fixedly connected to the back of the housing. An elastic frame is slidably connected to the inner wall of the protective cover and is slidably connected to the housing. A filter screen is fixedly connected to the inner wall of the elastic frame. A support plate is fixedly connected to the inner wall of the protective cover. A traction line is slidably connected to the inner wall of the support plate and is slidably connected to the protective cover and the filter screen. A spring is installed on the outer side of the traction line. One end of the spring is fixedly connected to the filter screen, and the other end of the spring is fixedly connected to the support plate. An end cap is fixedly sleeved on the outer side of the traction line and contacts the protective cover. The silent fan can dissipate heat from electrical components inside the housing. The filter screen can filter out dust and other particles in the air. The traction line, spring, and other structures can cause the filter screen to vibrate, cleaning impurities.

[0012] Furthermore, the lower end of the protective cover is fixedly connected to two symmetrically distributed contact pieces, each of which contacts the elastic frame. The contact pieces are made of stainless steel. Through the arrangement of the contact pieces, the elastic frame can be impacted and limited, so that the filter screen can vibrate and remove dust.

[0013] Furthermore, a limiting piece is fixedly connected to the back of the housing. The limiting piece is located on the upper side of the elastic frame and inside the protective cover. By setting the limiting piece, the elastic frame can be moved and limited. Attached Figure Description

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, a permanent magnet plate 25 is fixedly connected to the back of the housing 2 and to the upper right side of the iron plate 13. Multiple permanent magnet plates 25 are provided and are evenly distributed on the housing 2. The iron plate 13 can be magnetically fixed by the permanent magnet plates 25.

[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 As shown, a heat dissipation mechanism 7 is provided on the housing 2, which includes a silent fan 70. The silent fan 70 is installed inside the housing 2. A protective cover 71 is fixedly connected to the back of the housing 2. An elastic frame 72 is slidably connected to the inner wall of the protective cover 71. The elastic frame 72 is slidably connected to the housing 2.

A traction wire 77 is slidably connected to the inner wall of the support plate 76. The traction wire 77 is slidably connected to the protective cover 71 and fixed to the filter screen 73. The traction line 77 is connected to a spring 78 on its outer side. One end of the spring 78 is fixedly connected to the filter screen 73, and the other end of the spring 78 is fixedly connected to the support plate 76. An end cap 79 is fixedly sleeved on the outer side of the traction line 77. The end cap 79 contacts the protective cover 71.

[0023] The specific implementation process of this utility model is as follows: By setting the mounting ear 4, the access control terminal can be installed and used in conjunction with bolts and other fasteners. Under the magnetic attraction of the permanent magnet plate 14, the iron plate 13 can be made to fit stably, protecting the idle wire hole 8 and preventing the intrusion of foreign objects. When it is necessary to pass the cable, the iron plate 13 can be pushed to deflect, so that the iron plate 13 is separated from the permanent magnet plate 14 and drives the connecting plate 11 to rotate along the surface of the fixed rod 10, so that the connecting plate 11 slides along the surface of the limiting plate 12 to ensure the rotation stability of the connecting plate 11. Finally, the connecting plate 11 drives the iron plate 13 to contact the permanent magnet plate 15. Under the magnetic attraction, the iron plate 13 can be made to be stable, thereby exposing the wire hole 8. Under the action of the wire hole 8 and the protective ring 9, the cable and other wires can be passed through. The silent fan 70 and the heat dissipation slot 3 work together to ventilate the electrical components inside the housing 2, ensuring good heat dissipation efficiency. The filter screen 73 filters out dust and other impurities in the air, preventing them from affecting subsequent electrical components. The end cover 79 can be pulled upwards to move the traction line 77 and the filter screen 73 upwards, causing the elastic frame 72 to move and the spring 78 to deform. When the elastic frame 72 contacts the limiting piece 75, the end cover 79 can be released to allow the spring 78 to return to its original shape, pushing the filter screen 73 downwards. This causes the elastic frame 72 to contact and impact the contact piece 74, thereby causing the filter screen 73 to vibrate and remove dust, ensuring the flowability of the filter screen 73.

[0024] This solution utilizes the magnetic attraction of permanent magnet 14 to keep iron sheet 13 in a stable, close fit, sealing the unused wire hole 8 to prevent the intrusion of debris. The permanent magnet 15 and connecting piece 11 allow the iron sheet 13 to be deflected and opened for use. The wire hole 8 allows cables used in access control terminals to pass through. The protective ring 9 protects the cables, preventing damage to their sheaths. The silent fan 70 and heat dissipation trough 3 provide forced cooling for the electronic components inside the housing 2, ensuring efficient heat dissipation. The filter 73 removes dust and other particulate impurities from the air. Combined with the traction line 77, spring 78, and contact piece 74, the elastic frame 72 causes the filter 73 to vibrate, cleaning impurities and preventing clogging.
