Description

Technical Field

[0001] The utility model relates to the technical field of recorders, and more specifically, to a waterproof law enforcement recorder. Background Art

[0002] The waterproof law enforcement recorder is a portable recording device designed for law enforcement personnel. It is used to record the law enforcement process under various environmental conditions, especially in outdoor environments, to ensure the transparency and fairness of law enforcement activities.

[0003] In the existing technology, firstly, some devices are in a humid environment and lack components to provide dry hot air. Water vapor may condense inside the recorder, causing a short circuit or component damage. Without a heating function, the performance of the recorder in a low temperature environment may be affected or even fail to work properly. The durability and reliability of the equipment are reduced and the service life may be shortened. Secondly, some devices do not have the ability to accurately control the ventilation volume, which may cause the internal temperature of the recorder to be too high or too low, affecting the performance and life of the electronic components. When heat dissipation is required, the internal heat cannot be effectively removed, which may cause the equipment to overheat and affect performance and stability. In an environment with high sealing requirements, dust and water vapor cannot be effectively prevented from entering, affecting the cleaning and maintenance of the equipment. Utility Model Content

[0029] See also Figure 1-5 A waterproof law enforcement recorder includes a recorder body 1, a back clamping mechanism, a hot air blowing mechanism, an adjusting ventilation mechanism and a ventilation auxiliary mechanism. The adjusting ventilation mechanism includes a circulation pipe 2, a pushing frame 3, a push rod 4, a sealing head 5, a convex and concave block 6 and a convex and concave groove 7. The pushing frame 3 is movably installed in the interior of the circulation pipe 2, the push rod 4 is installed at the bottom of the pushing frame 3, the sealing head 5 is installed at one end of the push rod 4, the sealing head 5 is connected through the bottom of the circulation pipe 2, and the convex and concave groove 7 is opened on the sealing head 5, the convex and concave block 6 is installed at the semi-sealed part of one end of the circulation pipe 2, the ventilation auxiliary mechanism includes an adjusting pipe 8, a threaded block 9, an inner pushing pipe 10, a compression frame 11 and a reset spring 12, the threaded block 9 is installed at the top of the inner side of the adjusting pipe 8, the inner pushing pipe 10 is movably arranged in the interior of the circulation pipe 2, the outer surface of the inner pushing pipe 10 is threadedly connected to the threaded block 9, the compression frame 11 is installed on the push rod 4, and the compression frame 11 is connected to one end of the circulation pipe 2 with a reset spring 12.

[0030] In this embodiment, when the ventilation needs to be adjusted, the sealing head 5 is pushed to move along the circulation tube 2, and the ventilation volume is adjusted by the cooperation between the convex-concave block 6 and the convex-concave groove 7. The operator uses the ventilation auxiliary mechanism to move the pushing frame 3 in the circulation tube 2, thereby pushing the sealing head 5 to move along the circulation tube 2. The convex-concave groove 7 on the sealing head 5 cooperates with the convex-concave block 6 to form a sealed or semi-sealed state, thereby controlling the in and out of the ventilation volume. By changing the relative position between the sealing head 5 and the convex-concave block 6, the size of the ventilation volume can be accurately controlled to adapt to different environmental requirements. When the ventilation volume needs to be increased, the sealing head 5 is pushed to move away from the convex-concave block 6, thereby increasing the ventilation port and allowing more air to flow into the circulation tube 2. When the ventilation volume needs to be reduced, the sealing head 5 is pushed to move in the direction of the convex-concave block 6, thereby reducing the ventilation port and allowing less air to flow into the circulation tube 2. When the ventilation auxiliary mechanism needs to be operated, the operator rotates the adjusting tube 8 to make the threaded block 9 rotate on the outer surface of the inner push tube 10, thereby driving the inner push tube 10 to move in the circulation tube 2. The movement of the inner push tube 10 will change the ventilation channel inside the circulation tube 2, thereby affecting the ventilation volume. The compression frame 11 is connected to one end of the inner part of the adjusting tube 8 with a return spring 12. When the inner push tube 10 moves, the compression frame 11 will compress the return spring 12. The return spring 12 provides a restoring force. When the operator stops rotating the adjusting tube 8, the return spring 12 will return the adjusting tube 8 and the inner push tube 10 to their initial positions to keep the ventilation volume stable.

[0031] The hot air blowing mechanism includes a top platform 13, a hot air box 14, an air blowing fan 15 and an air blowing pipe 16. The top of the recorder body 1 is provided with a top platform 13, the hot air box 14 is installed on the top platform 13, the air blowing fan 15 is installed on the side of the hot air box 14, the air blowing pipe 16 is installed on the side of the hot air box 14, and the other end of the air blowing pipe 16 extends into and is connected to the recorder body 1.

[0032] When the hot air blowing mechanism needs to be operated, the blowing fan 15 is installed on the side of the hot air box 14. When the fan is started, it blows air into the hot air box 14. The air in the hot air box 14 is heated, and the heated hot air enters the recorder body 1 through the blowing pipe 16. In this way, the hot air blowing mechanism provides dry hot air for the recorder, which helps to keep the internal environment of the recorder dry, especially in a humid environment. By adjusting the air output by adjusting the ventilation mechanism, a stable internal air circulation is maintained to keep the inside of the recorder body 1 continuously dry.

[0033] See also Figure 1-5As a supplementary implementation method of a waterproof law enforcement recorder for the back clamping mechanism, the hot air blowing mechanism, the regulating ventilation mechanism and the ventilation auxiliary mechanism: side platforms 17 are provided on both sides of the recorder body 1, and one end of the blast pipe is connected to the side platform 17 on one side and extends into the interior of the recorder body 1, a fixed bottom plate 18 is provided at the bottom of the circulation pipe 2, and the circulation pipe 2 is fixedly connected to the side platform 17 on one side through the fixed bottom plate 18, and a back clamping mechanism is provided on the rear end face of the recorder body 1, and the back clamping mechanism includes a fixed clamping plate 19, a movable clamping plate 20, a rotating shaft 21 and a clamping spring 22 The movable splint 20 is movably mounted on the fixed splint 19 through a rotating shaft 21, and a clamping spring 22 is arranged between the fixed splint 19 and the movable splint 20, side plates 23 are arranged on the sides of the movable splint 20 and the fixed splint 19, and both ends of the rotating shaft 21 pass through the side plates 23 to connect the movable splint 20 and the fixed splint 19, a rubber pad 24 is arranged at the bottom end of one end of the movable splint 20 and the top end of one side of the fixed splint 19, a camera 25 is arranged on the front end face of the recorder body 1, a button 26 is arranged at the bottom of the camera 25, and the camera 25 and the button 26 are connected to the control component arranged inside the recorder body 1.

[0034] More specifically, when law enforcement officers use the recorder in a humid environment, the hot air blowing mechanism provides dry hot air to the inside of the recorder to keep the equipment dry and operating normally. When the ventilation volume needs to be adjusted, the amount of air entering the recorder can be accurately controlled by adjusting the ventilation mechanism and the ventilation auxiliary mechanism to adapt to different environmental conditions. The back clamping mechanism is used to fix the recorder on the uniform or other equipment of the law enforcement officer to provide stable support. The camera 25 and button 26 at the front end of the recorder body 1 are used to take videos or photos and control other functions of the recorder. The design of the entire device enables the law enforcement recorder to operate stably in various environments to ensure that the law enforcement process is recorded accurately.

[0035] In summary, when the overall equipment is in use or running: when the ventilation needs to be adjusted, the sealing head 5 is pushed to move along the circulation tube 2, and the ventilation volume is adjusted by the cooperation between the convex-concave block 6 and the convex-concave groove 7. The operator uses the ventilation auxiliary mechanism to move the pushing frame 3 in the circulation tube 2, thereby pushing the sealing head 5 to move along the circulation tube 2. The convex-concave groove 7 on the sealing head 5 cooperates with the convex-concave block 6 to form a sealed or semi-sealed state, thereby controlling the in and out of the ventilation volume. By changing the relative position between the sealing head 5 and the convex-concave block 6, the size of the ventilation volume can be accurately controlled to adapt to different environmental requirements. When the ventilation volume needs to be increased, the sealing head 5 is pushed to move away from the convex-concave block 6, thereby increasing the ventilation opening and allowing more air to flow into the circulation tube 2. When the ventilation volume needs to be reduced, the sealing head 5 is pushed to move in the direction of the convex-concave block 6, thereby reducing the ventilation opening and allowing less air to flow into the circulation tube 2.

[0036] When the ventilation auxiliary mechanism needs to be operated, the operator rotates the adjusting tube 8 to make the threaded block 9 rotate on the outer surface of the inner push tube 10, thereby driving the inner push tube 10 to move in the circulation tube 2. The movement of the inner push tube 10 will change the ventilation channel inside the circulation tube 2, thereby affecting the ventilation volume. The compression frame 11 is connected to one end of the inner part of the adjusting tube 8 with a return spring 12. When the inner push tube 10 moves, the compression frame 11 will compress the return spring 12. The return spring 12 provides a restoring force. When the operator stops rotating the adjusting tube 8, the return spring 12 will return the adjusting tube 8 and the inner push tube 10 to their initial positions to keep the ventilation volume stable.

[0037] When the hot air blowing mechanism needs to be operated, the blowing fan 15 is installed on the side of the hot air box 14. When the fan is started, it blows air into the hot air box 14. The air in the hot air box 14 is heated, and the heated hot air enters the recorder body 1 through the blowing pipe 16. In this way, the hot air blowing mechanism provides dry hot air for the recorder, which helps to keep the internal environment of the recorder dry, especially in a humid environment. By adjusting the air output by adjusting the ventilation mechanism, a stable internal air circulation is maintained to keep the inside of the recorder body 1 continuously dry.

[0038] When law enforcement officers use the recorder in a humid environment, the hot air blowing mechanism provides dry hot air to the inside of the recorder to keep the equipment dry and operating normally. When the ventilation volume needs to be adjusted, the amount of air entering the recorder can be accurately controlled by adjusting the ventilation mechanism and the ventilation auxiliary mechanism to adapt to different environmental conditions. The back clamping mechanism is used to fix the recorder on the uniform or other equipment of the law enforcement officer to provide stable support. The camera 25 and button 26 on the front end of the recorder body 1 are used to take videos or photos and control other functions of the recorder. The design of the entire device enables the law enforcement recorder to operate stably in various environments to ensure that the law enforcement process is recorded accurately.

In the above, all fixed connections are preferably welded. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model. The scope of the utility model is defined by the attached claims and their equivalents.
