Abstract
Description
Technical Field
[0001] This utility model relates to the field of camera accessories, specifically a high-stability road camera mounting base. Background Technology
[0002] Road cameras are important tools for ensuring traffic safety and maintaining traffic order. They can be classified according to their purpose as illegal parking cameras, electronic police cameras, checkpoint cameras, and section speed measurement cameras. Since road cameras are almost always used to capture images of a fixed location, they need to be stationary.
[0003] Traditional camera mounting bases are fixed with ordinary bolts. When the bolts loosen, the camera will shift or tilt, affecting the shooting angle. This requires timely maintenance by staff to ensure its effectiveness. Therefore, there is an urgent need for a highly stable road camera mounting base to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a highly stable road camera mounting base to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-stability road camera mounting base, comprising a support and fixing device and a camera, wherein the camera is fixedly mounted on the support and fixing device, the support and fixing device comprising a support base plate, four limiting support frames are uniformly and symmetrically fixedly connected to the bottom end of the support base plate, a first limiting insertion hole is provided through the middle of the limiting support frame, a limiting rod is movably inserted into the first limiting insertion hole, a plug is fixedly connected to the top end of the limiting rod, a rubber pad is provided on the outer side of the limiting rod, and the bottom of the limiting rod... The device has a threaded rod connected to its end. One end of the threaded rod is fixedly connected to a first conical extrusion plate. The end of the first conical extrusion plate away from the threaded rod is fixedly connected to a hexagonal bolt head. The end of the threaded rod away from the first conical extrusion plate is threadedly connected to a hexagonal nut and a second conical extrusion plate. The second conical extrusion plate is fixedly connected to the middle of the end of the hexagonal nut near the threaded rod. The bottom end of the limiting support frame near the end of the first conical extrusion plate has a second conical groove, and the bottom end of the limiting support frame near the end of the hexagonal nut has a first conical groove.
[0006] Preferably, a nested frame is fixedly connected to the center of the bottom end of the supporting base plate, and the nested frame is provided with evenly spaced insertion holes.
[0007] Preferably, the bottom of the camera is movably connected to a fixing plate, the bottom of the fixing plate is symmetrically provided with four second limiting holes, and the top of the fixing plate is symmetrically provided with four positioning grooves, the positioning grooves are located directly above the second limiting holes, and the second limiting holes and the positioning grooves are connected.
[0008] Preferably, the limiting rod passes through the positioning groove and the second limiting hole and is inserted into the inner side of the first limiting hole, the bottom end of the rubber pad is in close contact with the bottom end of the positioning groove, and the top end of the rubber pad is in close contact with the bottom end of the plug.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] This invention achieves active anti-loosening through a conical self-locking structure. The double-conical extrusion design, through the conical surface cooperation between the first conical extrusion plate and the second conical groove, and the second conical extrusion plate and the first conical groove, generates a radial component force on the conical inclined surface when tightening the hexagonal bolt head and hexagonal nut. This converts the rotational motion of the threaded rod into a vertical clamping force on the limiting support frame, forming a self-locking effect. Even if the bolt is slightly loosened by vibration, the conical structure can still maintain the preload through friction, avoiding the problem of rapid loosening of traditional planar butt bolts. The four limiting rods are inserted into the first limiting hole and the second limiting hole respectively, forming a four-point positioning constraint. Even if the threaded rod is accidentally loosened, the limiting rods can still maintain the camera's position through the first limiting hole, preventing the camera from shifting due to the loosening of traditional bolts.

Detailed Implementation
[0020] 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.
[0021] Please see Figure 1-4 This utility model provides an embodiment of a high-stability road camera mounting base, including a support and fixing device 1 and a camera 2. The camera 2 is fixedly mounted on the support and fixing device 1. The support and fixing device 1 includes a support base plate 3. A nested frame 4 is fixedly connected to the middle of the bottom end of the support base plate 3. The nested frame 4 is inserted and nested on the camera support rod. The nested frame 4 has evenly spaced insertion holes 5. A fixing bolt 6 is movably inserted into the inner side of the insertion hole 5. The fixing bolt 6 passes through the insertion hole 5 and the camera support rod to fix the nested frame 4. Because the nested frame 4 is fixed by the insertion and nesting method and the fixing bolt 6, the nested frame 4 will not tilt. Four limiting support frames 7 are evenly and symmetrically fixedly connected to the bottom end of the support base plate 3. A first limiting insertion hole 12 is opened through the middle of the limiting support frame 7. The inner part of the socket 12 is movably connected to a limiting rod 8. The top end of the limiting rod 8 is fixedly connected to a plug 10. A rubber pad 9 is provided on the outer side of the limiting rod 8. The bottom end of the limiting rod 8 is threadedly connected to a threaded rod 11. One end of the threaded rod 11 is fixedly connected to a first conical extrusion plate 15. The end of the first conical extrusion plate 15 away from the threaded rod 11 is fixedly connected to a hexagonal bolt head 16. The end of the threaded rod 11 away from the first conical extrusion plate 15 is threadedly connected to a hexagonal nut 17 and a second conical extrusion plate 18. The second conical extrusion plate 18 is fixedly connected to the middle of the end of the hexagonal nut 17 near the threaded rod 11. The bottom end of the limiting support frame 7 near the first conical extrusion plate 15 is provided with a second conical groove 14. The bottom end of the limiting support frame 7 near the hexagonal nut 17 is provided with a first conical groove 13.
[0022] The first conical extrusion plate 15 and the second conical extrusion plate 18 are both conical in design. The first conical slot 13 and the second conical slot 14 have a conical tip at one end near the first limiting insertion hole 12. The second conical slot 14 matches the first conical extrusion plate 15, and the first conical slot 13 matches the second conical extrusion plate 18. The limiting insertion rod 8 is inserted into the inner side of the first limiting insertion hole 12, and the threaded rod 11 is threaded to the outer bottom end of the limiting insertion rod 8. Due to the conical design of the second conical slot 14, the first conical extrusion plate 15, the first conical slot 13 and the second conical extrusion plate 18, when the first conical extrusion plate 15 and the second conical extrusion plate 18 approach the center, they respectively squeeze the top of the second conical slot 14 and the first conical slot 13, thereby driving the threaded rod 11 to move downward, thereby pulling the limiting insertion rod 8 downward to strengthen the fixation.
[0023] A fixed plate 19 is movably connected to the bottom of the camera 2. Four second limiting holes 20 are evenly and symmetrically opened at the bottom of the fixed plate 19, and four positioning grooves 21 are evenly and symmetrically opened at the top of the fixed plate 19. The positioning grooves 21 are located directly above the second limiting holes 20, and the second limiting holes 20 and the positioning grooves 21 are connected. The limiting rod 8 passes through the positioning grooves 21 and the second limiting holes 20 and is inserted into the inner side of the first limiting hole 12. The bottom end of the rubber pad 9 is tightly attached to the bottom end of the positioning groove 21, and the top end of the rubber pad 9 is tightly attached to the bottom end of the plug 10. The limiting rod 8 is locked at the bottom end of the positioning groove 21 through the plug 10, and is in contact with the bottom end of the positioning groove 21 through the rubber pad 9. When the limiting rod 8 is pulled down, the rubber pad 9 is squeezed and deformed to achieve the fit between the bottom end of the plug 10 and the top end of the positioning groove 21. The elastic deformation of the rubber can absorb vibration energy and compensate for the difference in expansion and contraction of metal parts caused by temperature changes, thereby reducing stress fatigue caused by rigid contact.
[0024] Working principle: In use, firstly, the support fixing device 1 is inserted into the camera support rod through the nested frame 4. Then, the nested frame 4 is fixed by the fixing bolt 6 passing through the insertion hole 5 and the camera support rod. Then, the camera 2 is placed on the top of the support base plate 3, so that the second limiting insertion hole 20 and the first limiting insertion hole 12 coincide. Then, the limiting insertion rod 8 is inserted into the inner side of the first limiting insertion hole 12 through the second limiting insertion hole 20. Then, the threaded rod 11 is threaded to the outer bottom end of the limiting insertion rod 8 by external force. The hexagonal bolt head 16 drives the first conical extrusion plate 15 and the threaded rod 11 to rotate closer to the nested frame 4. When the end of the threaded rod 11 away from the first conical extrusion plate 15 extends out of the bottom end of the limiting support frame 7, the hexagonal nut 17 and the second conical extrusion plate 18 are threaded onto the threaded rod 11. Then, the hexagonal nut 17 is locked and the hexagonal bolt head 16 is rotated until the outer side of the first conical extrusion plate 15 contacts the inner side of the second conical groove 14. Then, the hexagonal bolt head 16 and the hexagonal nut are rotated by external force respectively. 17. Due to the tapered design of the first tapered extrusion plate 15 and the second tapered groove 14, when the first tapered extrusion plate 15 moves closer to the limiting rod 8, it presses the bottom end of the limiting support frame 7. Since the limiting support frame 7 is fixed, under the push of the reverse force, the first tapered extrusion plate 15 drives the threaded rod 11 to move downward. The movement of the threaded rod 11 pulls the limiting rod 8 downward. The movement of the limiting rod 8 drives the plug 10 to move downward and press the rubber pad 9. Then, the hexagonal nut 17 is tightened by external force. The outer side of the second conical extrusion plate 18 is closely attached to the inner side of the first conical slot 13. The first conical extrusion plate 15 and the second conical extrusion plate 18 provide support to the bottom end of the limiting support frame 7, thereby ensuring the balanced force on the threaded rod 11 and thus ensuring the fixing strength of the camera 2. During regular maintenance, it is only necessary to check whether the threaded rod 11 is loose. When the threaded rod 11 is loose, since the four limiting rods 8 are respectively inserted into the inner side of the four first limiting holes 12, the camera 2 can still maintain the preset shooting angle.
