Description

Technical Field

[0001] This utility model relates to the field of monitoring technology, and in particular to an angle adjustment mechanism for a video monitor. Background Technology

[0002] Video surveillance is an important component of security systems. Due to its intuitiveness, accuracy, timeliness, and rich information content, video surveillance is widely used in many situations, including in inspection robots.

[0003] A search revealed Chinese patent CN221075862U, which discloses a remote intelligent adjustable monitor. The monitor includes a concave housing and a mounting housing fitted to the top of the concave housing, enabling smoother up-and-down movement and adjustment, thus improving stability during adjustment. However, it still has the following drawbacks: since most video monitors are installed at high locations, adjusting the angle requires climbing a ladder, which is not only inconvenient but also poses certain safety hazards. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a video surveillance angle adjustment mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A video surveillance camera angle adjustment mechanism includes a fixed plate and a video surveillance camera body. Two support plates are fixedly connected to one side of the fixed plate, and a connecting shaft is movably connected between the two support plates. A fixed block is fixedly connected to the outer side of the middle position of the connecting shaft, and an insertion port is provided inside the fixed block. An insertion block is fixedly connected to one end of the video surveillance camera body, and the insertion port is inserted into the insertion block. A detachable fixing component is provided between the fixed block and the video surveillance camera body. A first gear plate is fixedly connected to the outer side of the support plate. Both ends of the connecting shaft are provided with slots. A second gear plate is movably connected to the outer side of the connecting shaft, and the second gear plate is slidably connected to the slots. The second gear plate meshes with the first gear plate. A first spring is fixedly connected to the outer wall of one side of the second gear plate, and the first spring is fixed to the connecting shaft. A winding component is provided at both ends of the connecting shaft to drive its rotation.

[0007] As a further embodiment of this utility model, the fixing component includes a slide groove with a fixing block at the top. A slide frame is movably connected inside the slide groove, and a wedge block is fixedly connected to the bottom end of the slide frame.

[0021] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Therefore, all other embodiments of this application described herein, and all embodiments obtained by those skilled in the art without creative effort based on the embodiments in this application, should fall within the scope of protection of this application.

[0022] Referring to Figures 1-3, a video surveillance angle adjustment mechanism includes a fixed plate 2 and a video surveillance body 4. Two support plates 3 are bolted to one side of the fixed plate 2. A connecting shaft 12 is rotatably connected between the two support plates 3. Both ends of the connecting shaft 12 are equipped with winding assemblies that drive its rotation. A fixing block 1 is bolted to the outer side of the middle position of the connecting shaft 12. The winding assembly causes the connecting shaft 12 to drive the fixing block 1 to rotate, thereby causing the video surveillance body 4 to rotate upwards to the required angle. An insertion port 17 is provided inside the fixing block 1. One end of the video surveillance body 4 is bolted to an insertion block 18, and the insertion port 17 and insertion block 18 are inserted into each other. Through the cooperation of the insertion port 17 and insertion block 18, the fixing block 1 and the video surveillance body 4 are positioned and installed, avoiding repeated adjustments to the installation position, which is time-consuming and laborious. A detachable fixing assembly is provided between the fixing block 1 and the video surveillance body 4, facilitating disassembly and maintenance of the video surveillance body 4 by staff. The outer side of the connecting shaft 12 is fixed with a first gear 5 by bolts. Both ends of the connecting shaft 12 are provided with slots 8. The outer side of the connecting shaft 12 is slidably connected with a second gear 6, and the second gear 6 is slidably connected with the slots 8. The second gear 6 meshes with the first gear 5. A first spring 7 is welded to one side of the outer wall of the second gear 6, and the first spring 7 is fixed to the connecting shaft 12. At the same time, the connecting shaft 12 rotates, causing the second gear 6 to rotate. During the rotation, the second gear 6 is squeezed by the first gear 5, causing the second gear 6 to move outward along the slots 8. The first spring 7 resets the second gear 6 and re-engages with the first gear 5. This cycle repeats until the connecting shaft 12 stops rotating, thereby automatically fixing the angle of the adjusted video monitor body 4.

[0023] In this utility model, it should be noted that the fixing component includes a slide groove 16, the top of which is provided by the fixing block 1. A slide frame 15 is slidably connected inside the slide groove 16. A wedge block 13 is fixed to the bottom of the slide frame 15 by bolts. A second spring 19 is welded to the bottom of the slide frame 15 and is fixed to the bottom of the slide groove 16. The second spring 19 facilitates the automatic reset of the slide frame 15. A slot 14 is provided on the top of the video monitor body 4, and the wedge block 13 engages with the slot 14. Pressing down on the slide frame 15 causes the wedge block 13 to move out of the slot 14, and the second spring 19 retracts. Then, the video monitor body 4 is moved, causing the insertion block 18 to move out of the insertion port 17, thereby completing the disassembly of the video monitor body 4. The winding component includes two winding rollers 9, which are fixed to the connecting shaft 12 by bolts. At both ends, a pull rope 10 is wound inside the take-up roller 9. When the operator pulls one end of the pull rope 10 downwards, the take-up roller 9 unwinds and rotates, thereby causing the connecting shaft 12 to rotate. A counterweight 11 is installed at the bottom end of the pull rope 10. The counterweight 11 keeps the bottom end of the pull rope 10 under a certain weight, making it easy for the operator to locate it. At the same time, it prevents the pull end of the pull rope 10 from being easily blown to a high place during use. The connecting shaft 12 passes through the first toothed disc 5. The fixing block 1 is located between the two support plates 3. The two take-up rollers 9 have opposite winding directions, which makes it easy for the operator to rotate the video monitor body 4 upwards and downwards.

[0024] Working principle: When the camera angle of the video monitor body 4 needs to be adjusted, the operator first pulls a counterweight 11, causing the connected pull rope 10 to move. At the same time, the take-up roller 9 unwinds and rotates, causing the connecting shaft 12 to drive the fixed block 1 to rotate. This causes the video monitor body 4 to rotate upward to the required angle. Simultaneously, the rotation of the connecting shaft 12 causes the second gear 6 to rotate. During the rotation, the second gear 6 is squeezed by the first gear 5, causing the second gear 6 to move outward along the slot 8. The first spring 7 then resets the second gear 6 to re-engage with the first gear 5. This cycle repeats until the connecting shaft 12 stops rotating, thus automatically fixing the adjusted angle of the video monitor body 4. When the video monitor body 4 needs to be disassembled, the slide 15 is pressed down, causing the wedge block 13 to move out of the slot 14, and the second spring 19 to retract. Then, the video monitor body 4 is moved, causing the insert block 18 to... Remove the connector 17 to complete the disassembly of the video surveillance unit 4.
