Description

Technical Field

[0001] The present invention relates to the technical field of intelligent single-police equipment cabinets, and particularly to an intelligent single-police equipment cabinet with safety protection. Background Art

[0002] Intelligent single-police equipment cabinets are generally used in public security organs to store some single-police equipment, such as police uniforms, police guns, handcuffs, etc. Some single-police equipment is of certain danger. If stolen by lawbreakers, it will harm citizens. Therefore, the management of single-police equipment is relatively strict, and the requirements for intelligent single-police equipment cabinets are also relatively high.

[0003] The patent with the patent announcement number CN112568628B discloses an intelligent single-police equipment cabinet with safety protection, including: a cabinet body, the cabinet body is provided with a plurality of equipment boxes, and further includes a control console connected to the equipment boxes. The equipment box is divided into an upper box body and a lower box body. A pressure door panel is arranged at the opening of the equipment box, including a plurality of cross ribs fixed on the inner side of the pressure door panel and connected to the control console through electrical connectors, a plurality of side ribs fixed between two cross ribs and internally communicating with the cross ribs, and a plurality of pressure belts in a chain structure and evenly arranged at equal intervals in the cross ribs and side ribs and wrapped in two glass surfaces.

[0004] The existing intelligent single-police equipment cabinet judges whether there are lawbreakers damaging the pressure door panel through the pressure change of the pressure sensor, and then sends a signal to the entire alarm system to prompt the security personnel. However, when the intelligent single-police equipment cabinet is damaged by lawbreakers, the intelligent single-police equipment cabinet sometimes shakes. Since the single-police equipment is not fixed, the single-police equipment is easily shaken, resulting in a change in the position of relatively small single-police equipment or even mutual collision, so the protection effect on the single-police equipment is relatively weak. Now, an intelligent single-police equipment cabinet with safety protection that can clamp the single-police equipment and improve the protection effect is developed. Summary of the Invention

[0005] In order to overcome the shortcomings that the existing intelligent single-police equipment cabinet cannot clamp and fix the single-police equipment and has a relatively weak protection effect, the present invention provides an intelligent single-police equipment cabinet with safety protection that can clamp the single-police equipment and improve the protection effect.

[0006] An intelligent single-police equipment cabinet with safety protection, comprising a cabinet body, a protective door, an electronic door lock, a control system, a support frame, a load-bearing plate, a locking mechanism and a pressing mechanism. Support frames are symmetrically welded back and forth on both the left and right sides of the bottom of the cabinet body. Load-bearing plates for carrying single-police equipment are rotatably connected at the upper, middle and lower positions inside the cabinet body. Protective doors for protecting the front part of the cabinet body are rotatably connected on both the left and right sides of the front part of the cabinet body. Electronic door locks are rotatably connected on the sides close to each other at the front of the protective doors. When the two electronic door locks are rotated to a horizontal state, the two protective doors are locked. Control systems are installed on both the left and right sides of the top of the cabinet body. The control system includes a face recognition function, a fingerprint recognition function, a monitoring function, a light sensing function and an alarm function. After successful face recognition and fingerprint recognition, the control system opens the electronic door lock, and then rotates the electronic door lock to open the protective door. After recognition fails, the control system triggers the alarm function to emit lights and alarm sounds and reports to the background, so as to achieve the purpose of safety protection. Locking mechanisms for locking between the upper parts and the lower parts of the protective doors are provided at the upper and lower parts of the cabinet body. A pressing mechanism is provided at the upper part of the cabinet body. The pressing mechanism presses and cooperates with the load-bearing plate to clamp and fix the single-police equipment.

[0007] As a preferred technical solution of the present invention, the locking mechanism includes an upper sliding frame, a lower sliding frame, upper return springs, lower return springs and a connecting plate. An upper sliding frame for restricting the forward opening of the protective door is slidably connected to the front side of the upper part of the cabinet body. Upper return springs are connected between the left and right sides of the lower part of the upper sliding frame and the inner top wall of the cabinet body. The upper return springs are wound around the upper sliding frame. A lower sliding frame for restricting the forward opening of the protective door is slidably connected to the lower part of the cabinet body. A connecting plate is connected to the top of the lower sliding frame. Lower return springs are connected between the left and right sides of the bottom of the connecting plate and the inner bottom wall of the cabinet body. The lower return springs are wound around the lower sliding frame. If the protective door needs to be opened forward, the upper sliding frame is moved upward and the lower sliding frame is moved downward.

[0008] As a preferred technical solution of the present invention, the pressing mechanism includes a movable mesh plate, connecting arc-shaped plates, connecting rods and long return springs. Connecting arc-shaped plates are slidably connected to both the left and right sides of the rear wall inside the cabinet body. A movable mesh plate is welded between the front upper parts of the connecting arc-shaped plates. Movable mesh plates for fixing and limiting the top of the single-police equipment are also welded between the front lower parts of the connecting arc-shaped plates. Connecting rods are welded to both the left and right sides of the rear part of the inner top wall of the cabinet body. The connecting rods are slidably connected to the connecting arc-shaped plates. Long return springs are connected between the tops of the connecting arc-shaped plates and the inner top wall of the cabinet body. The long return springs are wound around the connecting rods respectively. The elastic force of the long return springs presses the connecting arc-shaped plates downward, so as to press the movable mesh plate downward to clamp and fix the top of the single-police equipment, and assist the control system to perform safety protection on the single-police equipment.

[0009] As a preferred technical solution of the present invention, there is also an up-and-down mechanism that automatically rotates the loading plate and lifts the movable mesh plate upward while opening the protective door. The up-and-down mechanism includes a connecting rope, a winding shaft, a connecting short plate, a rotating member, a connecting double plate, and an inclined hole plate. Winding shafts are welded to both the left and right sides of the rear part of the inner top wall of the cabinet. Connecting ropes are connected to the upper rear part of the protective door. The rear part of the connecting ropes bypasses the winding shafts. Connecting short plates are rotatably connected to both the left and right sides of the rear part of the loading plate. Rotating members are rotatably connected to the connecting short plates. Connecting double plates are rotatably connected between the two rotating members on the left and between the two rotating members on the right. The two rotating members above are both connected to the rear part of the connecting rope. When the protective door rotates forward and opens, it will pull the connecting rope forward, drive the rear part of the loading plate to lift upward through the rotating members and the connecting double plate, so as to take out the single-police equipment. Inclined hole plates are slidably connected to both the left and right sides of the inner top of the cabinet. The inclined hole plates are respectively connected to the adjacent connecting ropes. The inclined hole plates are slidably connected to the movable mesh plate. When the connecting rope drives the inclined hole plate to move forward, it will move the inclined hole plate forward, thereby automatically lifting the movable mesh plate upward to release the single-police equipment.

[0010] As a preferred technical solution of the present invention, there is also a clamping mechanism for clamping the sides of the single-police equipment. The clamping mechanism includes a fixed block, a clamping member, and a small return spring. Fixed blocks are evenly welded to the top of the loading plate. Clamping members are slidably connected to the fixed blocks. The fixed blocks and the clamping members cooperate to clamp the single-police equipment together. Small return springs are connected between the front and rear sides of the clamping members and the fixed blocks.

[0011] As a preferred technical solution of the present invention, there is also a reinforcement mechanism for reinforcing the protective door. The reinforcement mechanism includes a short round head plate, a long nail head plate, a large return spring, and a limit frame. Short round head plates are welded to the lower rear part of the protective door. Limit frames are bolted to both the left and right sides of the inner bottom wall of the cabinet. Long nail head plates are slidably connected to the limit frames. The long nail head plates are slidably connected to the cabinet. The front part of the long nail head plate is inserted into the short round head plate to lock the short round head plate. When the connecting plate moves downward, it will squeeze the long nail head plate downward, and the long nail head plate will separate from the short round head plate. A plurality of large return springs are evenly connected between the upper part of the long nail head plate and the cabinet.

[0012] As a preferred technical solution of the present invention, there is also a locking mechanism for locking the electronic door lock. The locking mechanism includes a long straight plate, a slider, and a fixing plate frame. Two long straight plates are connected between the front parts of the upper sliding frame and the lower sliding frame through bolts. Two sliders are slidably connected between the long straight plates. A fixing plate frame is connected between the front parts of the sliders through bolts.

[0013] As a preferred technical solution of the present invention, fixing columns are evenly connected to the upper parts of the fixed blocks and the clamping members, and the fixing columns are used to fix the top of the single-police equipment.

[0014] The beneficial effects of the present invention are as follows: 1. The present invention performs face recognition or fingerprint recognition through the control system. If the recognition is unsuccessful, the control system will trigger the alarm function and transmit the message to the background, enabling the background personnel to handle it in a timely manner. Moreover, when a criminal knocks on the cabinet body, the movable net plate keeps the top of the single-police equipment fixed, preventing the small single-police equipment from shifting and providing safety protection for the single-police equipment.

[0015] 2. The present invention uses the upper return spring and the lower return spring to lock the front parts of the two protective doors together by the upper sliding frame and the lower sliding frame, preventing the protective door from opening forward and further locking the protective door.

[0016] 3. When opening the protective door, the connecting rope is pulled, driving the loading plate to rotate and tilt, lifting the rear part of the single-police equipment upward. At the same time, the movable net plate automatically moves upward to release the single-police equipment, making it convenient to take out the single-police equipment.

[0017] 4. The present invention inserts the long spike head plate into the short round head plate to reinforce the protective door and improve its firmness. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0034] Referring to an embodiment herein means that the specific features, structures, or characteristics described in connection with the embodiment can be included in at least one embodiment of the present invention. The phrase appears in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0035] Embodiment 1

[0036] An intelligent single-police equipment cabinet with safety protection, as Figure 1 - Figure 2As shown in the figure, it includes a cabinet body 1, a protective door 2, an electronic door lock 21, a control system 3, a support frame 4, a loading plate 5, a locking mechanism 6 and a pressing mechanism 7. Support frames 4 are symmetrically welded to the front and back on both left and right sides of the bottom of the cabinet body 1. Loading plates 5 are rotatably connected at the upper, middle and lower positions inside the cabinet body 1. Protective doors 2 are rotatably connected to both left and right sides of the front of the cabinet body 1. Electronic door locks 21 are rotatably connected to the sides close to each other on the front of the protective doors 2. Control systems 3 are installed on both left and right sides of the top of the cabinet body 1. The control system 3 includes a face recognition function, a fingerprint recognition function, a monitoring function, a light sensing function and an alarm function. Locking mechanisms 6 are provided in the upper and lower parts of the cabinet body 1. A pressing mechanism 7 is provided in the upper part of the cabinet body 1.

[0037] As Figure 1 - Figure 5 shown, the locking mechanism 6 includes an upper sliding frame 61, a lower sliding frame 62, upper return springs 63, lower return springs 64 and a connecting plate 65. The upper sliding frame 61 is slidably connected to the front side of the upper part of the cabinet body 1. Upper return springs 63 are connected between the left and right sides of the lower part of the upper sliding frame 61 and the inner top wall of the cabinet body 1. The upper return springs 63 are wound around the upper sliding frame 61. The lower sliding frame 62 is slidably connected to the lower part of the cabinet body 1. A connecting plate 65 is connected to the top of the lower sliding frame 62. Lower return springs 64 are connected between the left and right sides of the bottom of the connecting plate 65 and the inner bottom wall of the cabinet body 1. The lower return springs 64 are wound around the lower sliding frame 62.

[0038] As Figure 2 , Figure 6 and Figure 7 shown, the pressing mechanism 7 includes a movable mesh plate 71, connecting arc angle plates 72, connecting rods 73 and long return springs 74. Connecting arc angle plates 72 are slidably connected to both left and right sides of the rear inner wall of the cabinet body 1. A movable mesh plate 71 is welded between the upper front parts of the connecting arc angle plates 72. A movable mesh plate 71 is also welded between the lower front parts of the connecting arc angle plates 72. Connecting rods 73 are welded to both left and right sides of the rear part of the inner top wall of the cabinet body 1. The connecting rods 73 are slidably connected to the connecting arc angle plates 72. Long return springs 74 are connected between the tops of the connecting arc angle plates 72 and the inner top wall of the cabinet body 1. The long return springs 74 are wound around the connecting rods 73 respectively.

[0039] When using an intelligent single-police equipment cabinet with safety protection, when people approach the cabinet body 1, the control system 3 will trigger the light sensing function and the monitoring function. The light sensing automatically turns on the light, and then fingerprint or face recognition is performed. If the recognition is successful, the electronic door lock 21 will be opened, and the electronic door lock 21 can rotate automatically, rotate the electronic door lock 21 to the vertical state, at the same time move the upper sliding frame 61 upward and move the lower sliding frame 62 downward. The upper return spring 63 and the lower return spring 64 are compressed, and the lower sliding frame 62 and the upper sliding frame 61 no longer restrict the opening of the protection door 2, so that the protection door 2 can be rotated forward to open. Then, the single-police equipment is placed on the loading plate 5. Under the action of the long return spring 74, the connecting arc angle plate 72 is driven to maintain a downward movement state, and the moving net plate 71 will clamp and fix the single-police equipment. Then, the protection door 2 is rotated backward to close, and then the electronic door lock 21 is manually rotated to reset, so that the protection door 2 can be locked. Then, the upper sliding frame 61 and the lower sliding frame 62 are released. Under the action of the upper return spring 63 and the lower return spring 64, the upper sliding frame 61 and the lower sliding frame 62 are driven to move and reset, and the front part of the protection door 2 is restricted again to prevent the protection door 2 from rotating forward to open. If the recognition is not successful, it is very likely that illegal elements want to steal. The electronic door lock 21 locks the protection door 2, and the control system 3 triggers the alarm function to emit light and alarm sound, and reports it to the background, and the background personnel will handle it. Moreover, if the illegal elements knock on the protection door 2 or even pound the entire cabinet body 1, the cabinet body 1 will vibrate, thereby vibrating the single-police equipment. And the single-police equipment is in a fixed state, which can prevent small single-police equipment from displacing, so as to achieve the purpose of safety protection for the single-police equipment.

[0040] Embodiment 2

[0041] On the basis of Embodiment 1, as Figure 2 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 shown, it further includes an up-down mechanism 8. The up-down mechanism 8 includes a connecting rope 81, a winding shaft 82, a connecting short board 83, a rotating part 84, a connecting double board 85 and an inclined hole board 86. Winding shafts 82 are welded on the left and right sides of the rear part of the inner top wall of the cabinet body 1. Connecting ropes 81 are connected to the rear upper parts of the protection doors 2. The rear parts of the connecting ropes 81 bypass the winding shafts 82. Connecting short boards 83 are rotatably connected to the left and right sides of the rear part of the loading plate 5. Rotating parts 84 are rotatably connected to the connecting short boards 83. Connecting double boards 85 are rotatably connected between the two rotating parts 84 on the left and between the two rotating parts 84 on the right. The two rotating parts 84 above are both connected to the rear parts of the connecting ropes 81. Inclined hole boards 86 are slidably connected to the left and right sides of the inner top of the cabinet body 1. The inclined hole boards 86 are respectively connected to the adjacent connecting ropes 81. The inclined hole boards 86 are slidably connected to the moving net plate 71.

[0042] Rotate the protective door 2 forward to open it, pull the connecting rope 81 forward. The connecting rope 81 drives the inclined hole plate 86 to move forward. The inclined hole plate 86 drives the movable net plate 71 to move upward automatically to loosen the single police equipment. The connecting rope 81 drives the rotating part 84 and the connecting double plate 85 to move upward, thus driving the rear part of the load-carrying plate 5 to lift upward. At this time, the load-carrying plate 5 rotates and tilts, so that people can take out the single police equipment. When the protective door 2 rotates backward to close and releases the connecting rope 81, under the action of the gravity of the single police equipment, the load-carrying plate 5 automatically rotates back to its original position. The load-carrying plate 5 pulls the rotating part 84 and the connecting double plate 85 downward to reset, so that the connecting rope 81 will be pulled back to its original position. The connecting rope 81 drives the inclined hole plate 86 to move backward to reset, so that the movable net plate 71 moves downward to reset and clamps and limits the top of the single police equipment again. Repeating the above operations can realize that when the protective door 2 is opened, the load-carrying plate 5 rotates and tilts automatically, and at the same time, the movable net plate 71 moves upward, facilitating the removal of the single police equipment.

[0043] As Figure 2 、 Figure 10 and Figure 11 shown, it further includes a clamping mechanism 9. The clamping mechanism 9 includes a fixed block 91, a clamping part 92 and a small return spring 93. Fixed blocks 91 are evenly welded on the top of the load-carrying plate 5. Fixed columns are evenly connected between the fixed blocks 91 and the upper part of the clamping part 92, and the fixed columns are used to fix the top of the single police equipment. The clamping parts 92 are slidably connected to the fixed blocks 91, and small return springs 93 are connected between the front and rear sides of the clamping parts 92 and the fixed blocks 91.

[0044] The single police equipment can be placed between the fixed block 91 and the clamping part 92. Under the action of the small return spring 93, the clamping part 92 can clamp and limit the left and right sides of the single police equipment, and the fixed column fixes the top of the single police equipment.

[0045] As Figure 2 、 Figure 12 and Figure 13 shown, it further includes a reinforcement mechanism 10. The reinforcement mechanism 10 includes a short round head plate 101, a long nail head plate 102, a large return spring 103 and a limit frame 104. Short round head plates 101 are welded on the lower rear part of the protective door 2. Limit frames 104 are bolted to the left and right sides of the inner bottom wall of the cabinet body 1. The long nail head plates 102 are slidably connected to the limit frames 104, and the long nail head plates 102 are slidably connected to the cabinet body 1. Four large return springs 103 are evenly connected between the upper part of the long nail head plate 102 and the cabinet body 1.

[0046] When the protective door 2 is in the closed state, the long spike head plate 102 is in a state of being inserted into the short round head plate 101, which can reinforce the protective door 2. When it is necessary to open the protective door 2, move the lower sliding frame 62 downward to drive the connecting plate 65 downward. The downward movement of the connecting plate 65 and the long spike head plate 102 causes them to separate from the short round head plate 101, and the large return spring 103 is stretched. At this time, the long spike head plate 102 and the short round head plate 101 are separated, and then people can rotate the protective door 2 forward to open it. When it is necessary to close the protective door 2, the short round head plate 101 can be reset, and then the upward movement of the lower sliding frame 62 will drive the connecting plate 65 upward to reset and release the long spike head plate 102. Under the action of the large return spring 103, the long spike head plate 102 is driven upward to reset and re-insert into the short round head plate 101 to reinforce the protective door 2.

[0047] As Figure 1 , Figure 2 , Figure 14 and Figure 15 shown, it further includes a locking mechanism 11. The locking mechanism 11 includes a long straight plate 111, a slider 112, and a fixed plate frame 113. Two long straight plates 111 are connected between the front parts of the upper sliding frame 61 and the lower sliding frame 62 through bolts. Two sliders 112 are slidably connected between the long straight plates 111. A fixed plate frame 113 is connected between the front parts of the sliders 112 through bolts.

[0048] When it is necessary to open the electronic door lock 21, first remove the fixed plate frame 113, then move the upper slider 112 upward and the lower slider 112 downward. The slider 112 no longer locks the electronic door lock 21. At the same time, remove the long straight plate 111. When closing the electronic door lock 21, the long straight plate 111 is installed between the front parts of the upper sliding frame 61 and the lower sliding frame 62 through bolts, then reset the slider 112 to lock the electronic door lock 21, and then reinstall the long straight plate 111. In this way, the electronic door lock 21 can be locked, achieving the effect of strengthening the protection.

[0049] Although the present disclosure has been shown and described with reference to specific exemplary embodiments of the present disclosure, those skilled in the art should understand that various changes in form and detail can be made to the present disclosure without departing from the spirit and scope of the present disclosure as defined by the appended claims and their equivalents. Therefore, the scope of the present disclosure should not be limited to the above embodiments, but should be determined not only by the appended claims but also by the equivalents of the appended claims.
