Description

Technical Field

[0001] This utility model relates to the field of auxiliary devices for security equipment, and in particular to an auxiliary device for security equipment. Background Technology

[0002] The installation and fixation of surveillance equipment such as cameras rely on various auxiliary support devices. Their conventional structure mainly includes a support frame fixedly connected to a mounting surface such as a wall, column, or ceiling, and a mounting platform to support the monitor. The monitor is usually fixed to the support frame via bolts. While this traditional connection method is simple in structure and low in cost, it has significant drawbacks in practical applications:

[0003] When fine-tuning the horizontal azimuth or vertical pitch angle of the monitor is required after installation, the operator must first loosen the connecting bolts to release the rigid fixing state. Then, based on experience, the operator manually adjusts the monitor to the desired observation angle. During this adjustment process, because the bolts are loose, the monitor often shifts or sags unexpectedly due to its own weight or slight external force, causing the initially adjusted angle to be inaccurate. Repeated attempts are often required to achieve the correct positioning. Finally, the bolts need to be tightened again. However, the tightening torque generated during bolt tightening inevitably causes relative displacement between the bracket and the monitor, resulting in a slight deviation in the angle again, making it difficult to achieve accurate positioning. This not only significantly reduces the efficiency of installation and debugging but also increases the operational difficulty and safety risks for personnel working at height. Furthermore, after long-term use, the bolt interfaces may loosen due to vibration, causing the monitoring angle to drift, requiring frequent maintenance and correction, resulting in insufficient reliability.

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] Examples, such as Figures 1 to 4 As shown, this utility model proposes an auxiliary device for security equipment, including a support frame 1 and a monitor 2 mounted on the support frame 1. The monitor 2 monitors the monitored area to achieve security monitoring. A first connecting seat 11 is rotatably mounted on the support frame 1, and a second connecting seat 21 is fixedly mounted on the monitor 2. It also includes a connecting component 3 mounted on the brackets of the first connecting seat 11 and the second connecting seat 21. The connecting component 3 includes a connecting rod 31 fixedly mounted on the second connecting seat 21, a sliding rod 35 slidably mounted on the first connecting seat 11, and a mechanism between the connecting rod 31 and the sliding rod 35 that converts the rotational movement of the connecting rod 31 into... The transmission assembly for the axial sliding of the slide rod 35 requires the second connecting seat 21 and the connecting rod 31 to rotate when the elevation angle of the monitor 2 is adjusted. The transmission assembly then causes the slide rod 35 to slide along its axial direction. A limiting assembly 36 is installed on the first connecting seat 11 to limit the movement of the slide rod 35. When the slide rod 35 cannot slide, the connecting rod 31 cannot rotate, which in turn prevents the second connecting seat 21 and the monitor 2 from rotating. This allows the elevation angle of the monitor 2 to be adjusted. The connecting component 3 can also be installed between the support frame 1 and the first connecting seat 11 to facilitate the adjustment of the horizontal angle of the monitor 2.

[0023] Furthermore, the transmission assembly includes a crank 32 fixedly mounted on the connecting rod 31, a connecting rod 33 rotatably mounted on the crank 32, and a mounting plate 34 rotatably mounted on the other end of the connecting rod 33. The sliding rod 35 is fixedly connected to the mounting plate 34. When the connecting rod 31 rotates, it will drive the crank 32 to rotate synchronously, thereby driving the connecting rod 33 to swing. The swinging connecting rod 33 will push or pull the mounting plate 34 to move up and down, thereby causing the sliding rod 35 to move axially with the rotation of the connecting rod 31.

[0024] In this embodiment, the limiting component 36 includes a limiting cylinder 361 fixedly installed on the first connecting seat 11 and a sealing plate 362 slidably and sealingly connected inside the limiting cylinder 361. The sealing plate 362 is fixedly connected to the sliding rod 35. The two ends of the limiting cylinder 361 are connected through a conveying pipe 365. A valve 366 is fixedly installed on the conveying pipe 365. Both the limiting cylinder 361 and the conveying pipe 365 are filled with hydraulic medium, which is a liquid that cannot be compressed under working conditions. When the connecting rod 31 rotates, that is, when the sliding rod 35 slides, it will carry... The movable sealing plate 362 moves up and down. At this time, the hydraulic medium on one side of the sealing plate 362 needs to be squeezed to the other side of the sealing plate 362 before it can move. Therefore, when the valve 366 is open, the sealing plate 362 can slide freely, so the elevation angle of the monitor 2 can be freely adjusted. When the valve 366 is closed, the sealing plate 362 cannot move, thus fixing the monitor 2. The resistance that the sealing plate 362 bears when moving can be controlled by controlling the opening size of the valve 366, thereby preventing the monitor 2 from becoming too loose during the adjustment process.

[0025] The sealing plate 362 is fixedly installed with a first sealing ring 363, and the limit cylinder 361 and the slide rod 35 are slidably connected with a second sealing ring 364. The first sealing ring 363 can ensure that the hydraulic medium on both sides of the sealing plate 362 does not flow to each other, and the second sealing ring 364 can prevent the hydraulic medium from flowing to the outside of the limit cylinder 361.

[0026] like Figure 1 and Figure 5 As shown, a connector 4 is installed at one end of the support frame 1, which fixes the support frame 1 to the mounting surface. When the support frame 1 is installed on a hollow pole, such as a street lamp bracket, it is not easy to maintain the stability of the connection by bolts. Since the wall thickness of the hollow tube is relatively thin, it is difficult to maintain the stability of the threaded connection. In this case, the connector 4 can maintain the stability of the connection. The connector 4 includes a threaded post 41 installed on the support frame 1 and a connector head 42 fixedly installed at one end of the threaded post 41. A baffle 43 is rotatably installed on the connector head 42, and a positioning head 4 is fixedly installed at the other end of the threaded post 41. 4. A nut 45 is threaded onto the threaded post 41. The diameter of the connector 42 is smaller than that of the threaded post 41, and the outer tangent diameter of the positioning head 44 is smaller than that of the inner diameter of the nut 45. When making the connection, rotate the baffle 43 so that the baffle 43 is close to the direction parallel to the axis of the threaded post 41. At this time, the connector 42 and the baffle 43 can be inserted into the hole on the hollow tube. Then, shake the connector 42 to keep the baffle 43 perpendicular to the threaded post 41, and use a tool to circumferentially position the positioning head 44. Then, rotate the nut 45 to fix the threaded post 41 on the hollow tube and maintain the stability of the connection.

[0027] In this embodiment, when the angle of the monitor 2 needs to be adjusted, the operator changes the opening degree of the valve 366 in the limiting component 36 by controlling the valve 366. When the valve 366 is open, the hydraulic medium filled in the limiting cylinder 361 and its delivery pipe 365 can flow freely, allowing the sealing plate 362 to slide together with the slide rod 35. At this time, rotating the monitor 2 will drive the second connecting seat 21 and the connecting rod 31 on it to rotate. The connecting rod 31 drives the connecting rod 33 to move through the crank 32 fixed on it. The connecting rod 33 then pushes the mounting plate 34 fixedly connected to the slide rod 35, converting the rotational motion of the connecting rod 31 into the linear sliding of the slide rod 35, thereby realizing the angle adjustment. When the desired angle is reached, the valve 366 is closed, the flow of hydraulic medium is blocked, the sliding of the sealing plate 362 and the slide rod 35 is suppressed, and then locked by the transmission component and the connecting rod 31, finally making the monitor 2 stably fixed at the target angle.

[0028] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
