Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1-3This utility model provides an embodiment of a video transmission device that is easy to install, including a video transmission device 1 and a fixed housing 2. The video transmission device 1 is stably installed through the cooperation of the fixed housing 2 and the fixed legs 12 for video signal transmission. The fixed housing 2 supports clamping components such as a rotating column 4 and a pressing block 7, as well as transmission components such as a knob 16 and a gear set, limiting the movement trajectory of each component and providing a fixed space for the video transmission device 1. The rotating column 4 is rotatably connected to the inner wall of the fixed housing 2. The rotating column 4 drives the fixed gear 5 to rotate, transmitting the power required for the clamping action and connecting the power transmission between the helical gear 25 and the fixed gear 5. The fixed gear 5 is fixedly connected to the outer wall of the rotating column 4. The fixed gear 5 meshes with the fixed gear 6, transmitting the power of the rotating column 4. The force is transmitted to the extrusion block 7, driving it to rotate. A second fixed gear 6 meshes with the outer wall of the first fixed gear 5, causing the extrusion block 7 to rotate synchronously. This connects the power transmission between the first fixed gear 5 and the extrusion block 7. The extrusion block 7 is fixedly connected to the inner wall of the second fixed gear 6. The extrusion block 7 rotates along the inner wall of the fixed cylinder 11, pushing the connecting column 9 and the moving block 10 through the arc-shaped hole 8, thus clamping the fixed leg 12. The outer wall of the extrusion block 7 has an arc-shaped hole 8, which guides the connecting column 9 to slide the moving block 10 towards the fixed leg 12, ensuring precise clamping. The inner wall of the arc-shaped hole 8 is slidably connected to the connecting column 9, which connects the extrusion block 7 and the moving block 10, transmitting the rotational thrust of the extrusion block 7 and converting it into a moving force. The clamping force of block 10 is achieved by connecting the bottom of the connecting column 9 to a movable block 10. The movable block 10 slides along the outer wall of the fixed cylinder 11, moves towards the fixed leg 12 and tightly abuts against it, precisely clamping the fixed leg 12 from both sides to enhance the connection strength. The fixed cylinder 11 is fixedly connected to the inner wall of the fixed shell 2. The fixed cylinder 11 is fixed to the inner wall of the fixed shell 2, supporting the rotation of the pressing block 7, limiting the sliding direction of the movable block 10, preventing deviation, and ensuring smooth clamping action. The outer wall of the movable block 10 abuts against the fixed leg 12. The fixed leg 12 connects the fixed base 3 and the fixed shell 2, providing installation support for the equipment. It is fixed by plugging and clamping with the fixed shell 2. The bottom of the fixed leg 12 is fixedly connected to the fixed base 3. The fixed base 3 is fixed to the bottom of the fixed leg 12 and fits against the wall surface of the mounting surface. The bracket, through the mounting hole 26, achieves basic positioning of the equipment and prevents installation misalignment. A pull rod 13 is slidably connected to the inner wall of the fixed shell 2. The pull rod 13 drives the wedge block 14 to move, releasing the initial locking of the fixed leg 12, making it easy to pull out the fixed leg 12 for repositioning. The inner wall of the fixed shell 2 is elastically connected to the wedge block 14 through a spring 15. The spring 15 provides a reset elastic force for the wedge block 14, pushing the wedge block 14 into the slot of the fixed leg 12 to maintain the initial locking state. The wedge block 14 is inserted into the slot of the inner wall of the fixed leg 12, forming an initial lock to prevent the fixed leg 12 from coming out on its own and to provide a guarantee for subsequent clamping. The outer wall of the wedge block 14 is inserted into the inner wall of the fixed leg 12, and the outer wall of the fixed leg 12 is inserted into the inner wall of the fixed shell 2. The outer wall of the pull rod 13 is fixedly connected to the side wall of the wedge block 14.

[0020] Reference Figures 1-3 A knob 16 is rotatably connected to the inner wall of the fixed housing 2. The knob 16 provides manual power for the clamping action, driving the helical gear 18 to rotate. Simultaneously, a ratchet 17 provides one-way locking. A ratchet 17 is fixedly connected to the outer wall of the knob 16, engaging with a pawl 29 to form a one-way lock, preventing the knob 16 from rotating in the opposite direction and causing the clamping to loosen. A pull rod 27 is slidably connected to the inner wall of the fixed housing 2. The pull rod 27 drives the pawl 29 to disengage from the ratchet 17, releasing the knob 16 from locking and facilitating the reverse rotation of the knob 16 to loosen the fixed leg 12. The inner wall of the fixed housing 2 is elastically connected to the pawl 29 via a spring 28, which provides spring force to the pawl 29. The force of the thrust maintains the engagement of the pawl 29 and the ratchet 17, keeping the clamp locked. The engagement of the pawl 29 and the ratchet 17 locks the position of the knob 16, preventing the knob 16 from reversing due to the weight of the equipment or vibration, ensuring a stable and long-lasting clamping state. The outer wall of the pawl 29 is engaged with the outer wall of the ratchet 17. The outer wall of the pull rod 27 is fixedly connected to the outer wall of the pawl 29. The outer wall of the knob 16 is fixedly connected to the helical gear 18. The helical gear 18 engages with the helical gear 19, changing the direction of power transmission and transmitting the power of the knob 16 to the rotating rod 20. The outer wall of the helical gear 18 is engaged with the helical gear 19. The helical gear 19 drives the rotating rod 20 to rotate, connecting the helical gears. The power transmission between the rotating rod 18 and the rotating rod 20 is achieved through a helical gear 29 with the rotating rod 20 fixedly connected to its inner wall. The rotating rod 20 drives the worm gears 21 at both ends to rotate synchronously, transmitting power to the worm wheel 22 and the rotating rod 23. Worms 21 are fixedly connected to both ends of the rotating rod 20, and the worm gears 21 mesh with the worm wheel 22, changing the direction of power transmission and driving the rotating rod 23 to rotate. The worm wheel 22 is meshed with the outer wall of the worm gear 21, driving the rotating rod 23 to rotate, thus connecting the power transmission between the worm gears 21 and the rotating rod 23. The rotating rod 23 is fixedly connected to the inner wall of the worm wheel 22, and the rotating rod 23 drives the helical gears 24 at both ends to rotate, transmitting power to the helical gears. Wheel 4 25 and rotating column 4, and both ends of rotating rod 2 23 are fixedly connected to helical gear 3 24. Helical gear 3 24 meshes with helical gear 4 25 to change the power transmission direction and transmit the power of rotating rod 2 23 to rotating column 4. Helical gear 4 25 is meshed with the outer wall of helical gear 3 24. Helical gear 4 25 drives rotating column 4 to rotate, connecting the power transmission between helical gear 3 24 and rotating column 4 to ensure stable output of clamping power. The inner wall of helical gear 4 25 is fixedly connected to the outer wall of rotating column 4. The outer wall of video transmission device 1 is fixedly connected to the inner wall of fixed shell 2. The inner wall of moving block 10 is slidably connected to the outer wall of fixed cylinder 11. The inner wall of fixed cylinder 11 is rotatably connected to the outer wall of extrusion block 7. Reference Figures 2-4One end of spring 15 is fixedly connected to the inner wall of the fixed shell 2, and the other end of spring 15 is fixedly connected to the side wall of wedge 14. One end of spring 28 is fixedly connected to the inner wall of the fixed shell 2, and the other end of spring 28 is fixedly connected to the side wall of pawl 29. The outer wall of the fixed base 3 is provided with mounting holes 26. The mounting holes 26 are provided on the outer wall of the fixed base 3 to provide an interface for fixing components such as bolts, so as to achieve the initial fixing of the fixed base 3 and the mounting surface. The outer wall of rotating rod 120 is rotatably connected to the inner wall of the fixed shell 2, and the outer wall of rotating rod 23 is rotatably connected to the inner wall of the fixed shell 2.

[0021] Working principle: The video transmission device 1 is pre-fixed on the inner wall of the fixed housing 2. The fixing leg 12 is aligned with the insertion slot on the inner wall of the fixed housing 2, and the fixing leg 12 is pushed into the fixed housing 2. At the same time, the fixing base 3 at the bottom of the fixing leg 12 is attached to the mounting surface such as a wall or bracket. Through the mounting hole 26 on the outer wall of the fixing base 3, the fixing base 3 can be initially fixed on the mounting surface using bolts and other components to achieve the basic positioning of the equipment and prevent the equipment from shifting during the installation process. When the fixing leg 12 is inserted into the fixing shell 2, the wedge 14, under the elastic force of the spring 15, inserts into the groove on the inner wall of the fixing leg 12, forming a preliminary lock to prevent the fixing leg 12 from coming out on its own during subsequent installation, thus ensuring precise clamping. If the position of the fixing leg 12 needs to be adjusted, pull the pull rod 13, which will cause the wedge 14 to compress the spring 15 and disengage from the fixing leg 12, allowing the fixing leg 12 to be pulled out and repositioned. Rotating the knob 16 on the inner wall of the fixed shell 2 causes the helical gear 18 on the outer wall to rotate. The helical gear 18 meshes with and drives the helical gear 29, which in turn drives the rotating rod 20 to rotate along the inner wall of the fixed shell 2. The worm gears 21 at both ends of the rotating rod 20 rotate synchronously and mesh with and drive the corresponding worm gears 22. The worm gears 22 drive the rotating rod 23 to rotate. The helical gears 324 at both ends of the rotating rod 23 mesh with and drive the helical gear 425, which finally drives the rotating column 4 to rotate along the inner wall of the fixed shell 2, ensuring stable power output for subsequent clamping actions.

[0022] When the rotating column 4 rotates, the fixed gear 5 on the outer wall of the rotating column 4 meshes with the fixed gear 6, which drives the extrusion block 7 to rotate along the inner wall of the fixed cylinder 11. The arc-shaped hole 8 on the outer wall of the extrusion block 7 pushes the moving block 10 to slide along the outer wall of the fixed cylinder 11 through the connecting column 9. The fixed cylinder 11 provides guidance for the moving block 10 to avoid deviation. The moving block 10 moves towards the fixed leg 12 until it is tightly abutted against the outer wall of the fixed leg 12, forming a precise clamping on the fixed leg 12 from both sides, further enhancing the connection strength between the fixed leg 12 and the fixed shell 2, ensuring that the equipment is not loose after installation, and resisting external vibration or slight impact. During the rotation of knob 16, the ratchet 17 on the outer wall of knob 16 rotates synchronously. The pawl 29 on the inner wall of the fixed housing 2 is always engaged with the ratchet 17 under the elastic force of spring 28, forming a one-way lock. This prevents knob 16 from rotating in the opposite direction due to the weight of the equipment, vibration, or other factors, thereby preventing the squeezing block 7 and the moving block 10 from loosening and ensuring a stable clamping state. If disassembly or adjustment is required, pull the pull rod 27 to cause the pawl 29 to compress the spring 28 and disengage from the ratchet 17. Then, knob 16 can be rotated in the opposite direction to reset the moving block 10 and release the fixed leg 12.
