Description
Technical Field
[0001] The utility model relates to the technical field of monitoring cameras, and in particular to a fixing device for a large-angle traffic monitoring camera. Background Art
[0002] Traffic surveillance cameras, also known as "electronic police," are crucial equipment in road traffic management. They monitor traffic conditions in real time, including vehicle trajectories and traffic flow, providing real-time data support to traffic management departments. Using high-definition imaging and intelligent recognition technology, these cameras can quickly capture and record traffic violations, such as running red lights, driving over lane lines, driving outside designated lanes, driving against traffic, illegal lane changes, and illegal parking. These records provide strong evidence for traffic management departments to enforce the law. In the event of a traffic accident, traffic surveillance cameras can record the entire process, providing crucial evidence for handling and determining responsibility. Traffic surveillance cameras play a vital role in maintaining traffic order, ensuring road safety, and improving travel efficiency. By monitoring and recording traffic violations in real time, they effectively curb traffic chaos and provide strong support for urban traffic management. Furthermore, these cameras serve as a crucial basis for decision-making in urban planning and road construction.
[0003] Currently, most traffic surveillance cameras are fixed in specific locations, with limited monitoring angles, making them difficult to meet the needs of comprehensive monitoring in complex traffic environments. Existing mounting systems often only allow for adjustment of the camera's angle within a narrow range, typically by tightening or loosening bolts. This requires tools and is a complex process, hindering rapid response and flexible deployment. Therefore, a simple, easily adjustable mounting system for traffic surveillance cameras is urgently needed. Utility Model Content
[0004] In response to the existing deficiencies, the present invention provides a large-angle traffic monitoring camera fixing device, which solves the problems raised in the above-mentioned background technology. The device realizes multi-angle adjustment of the camera and expands the monitoring range through optimized structural design, while simplifying the installation and maintenance process and improving monitoring efficiency.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0006] A large-angle traffic monitoring camera fixing device includes a square tube bracket and a fixing seat, wherein the left end of the square tube bracket is fixed with a fixing seat, and two groups of U-shaped bolts are installed on the outside of the fixing seat by bolts, and the right end of the square tube bracket is fixed with an arc-shaped structure connecting frame, and the inner side of the connecting frame is connected to a hollow structure hemispherical seat by an axis rotation, and the upper side of the hemispherical seat is fixed with a cylinder seat, and the upper side of the cylinder seat is equipped with a rotatable top seat, and an axle sleeve is provided at the center of the inner circle of the cylinder seat, and the annular surface of the axle sleeve is fixedly connected to the inner wall of the cylinder seat by multiple groups of spoke rods, and a fixed shaft is fixed with the top of the inner wall of the top seat, and the fixed shaft is inserted through the axle sleeve.
[0007] Furthermore, a circle of micro-teeth is fixedly provided on the surface of the fixed shaft ring, and a circle of micro-tooth grooves adapted to the micro-teeth are provided on the inner wall of the shaft sleeve.
[0008] Furthermore, a blocking piece is fixedly provided at the bottom of the fixed shaft, and a supporting spring is sleeved on the fixed shaft between the blocking piece and the shaft sleeve.
[0009] Furthermore, a limit ring is fixed on the annular surface of the cylinder seat, and two groups of spaced limit snap rings are fixed on the inner annular surface of the top seat. When the top seat is clamped on the cylinder seat, the limit ring is located between the two groups of limit snap rings.
[0010] Furthermore, an incomplete gear ring is vertically arranged on the annular surface of the hemispherical seat, a guide plate is fixedly provided on the right side inside the square tube bracket, a push rod is penetrated inside the guide plate, the right end of the push rod is fixedly connected with a latch tooth that is adapted to the incomplete gear ring, and the latch tooth extends from the right end of the square tube bracket and the inside of the connecting frame, a pull rod handle is fixedly provided on the lower side of the annular surface of the push rod, a slide groove is provided on the bottom surface of the square tube bracket, and the lower end of the pull rod handle extends from the slide groove.
[0011] Furthermore, a return spring is sleeved on the push rod between the pull rod handle and the guide plate.
[0012] Furthermore, a mounting seat is fixedly provided on the top of the top seat, and a plurality of groups of arc-shaped anti-slip grooves are provided on the annular surface of the top seat.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] 1. The utility model realizes large-angle adjustment of the camera in the horizontal and vertical directions through the rotation connection of the arc-shaped structure connecting frame and the hemispherical seat, as well as the rotatable design of the cylinder seat and the top seat, so that the camera can cover different monitoring areas and improve the flexibility and comprehensiveness of monitoring.
[0015] 2. Existing fixing devices often require the use of loosening and tightening bolts to adjust the angle of the camera, which is complicated and requires tools. However, this device, through the design of a hemispherical seat and a top seat, allows users to easily and quickly adjust the angle of the camera, and can also lock the angle without using any tools, greatly improving the convenience of adjustment.
[0016] 3. In this utility model, the fixed shaft is provided with a ring of micro-teeth on its annular surface, and the inner wall of the sleeve is provided with a ring of micro-tooth grooves that match the micro-teeth.

[0027] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0028] Example:
[0029] like Figures 1 to 7 As shown, a large-angle traffic monitoring camera fixing device includes a square tube bracket 3 and a fixing base 2. The left end of the square tube bracket 3 is fixed with a fixing base 2. Two groups of U-shaped bolts 1 are installed on the outside of the fixing base 2 by bolts. The right end of the square tube bracket 3 is fixed with an arc-shaped structure connecting frame 6. The inner side of the connecting frame 6 is connected to a hollow structure hemispherical seat 7 by an axis rotation. A cylinder seat 11 is fixed on the upper side of the hemispherical seat 7. A rotatable top seat 5 is assembled on the upper side of the cylinder seat 11. A shaft sleeve 18 is provided at the center of the inner circle of the cylinder seat 11. The annular surface of the shaft sleeve 18 is fixedly connected to the inner wall of the cylinder seat 11 by multiple groups of spoke rods 10. A fixed shaft 9 is fixed on the top of the inner wall of the top seat 5, and the fixed shaft 9 is inserted through the shaft sleeve 18. This design solves the problem that the existing fixing device can often only achieve angle adjustment of the camera within a small range, and the angle of the camera is usually adjusted by tightening the bolts. Tools are required for adjustment, and the adjustment process is complicated, which is not conducive to rapid response and flexible deployment.
[0030] In this embodiment, a ring of micro-teeth 24 is fixedly formed on the annular surface of the fixed shaft 9, and a ring of micro-tooth grooves 21 is formed on the inner wall of the sleeve 18, which are adapted to the micro-teeth 24. When the fixed shaft 9 is inserted into the sleeve 18, the micro-teeth 24 and micro-tooth grooves 21 tightly engage, effectively securing the fixed shaft 9 in position and effectively preventing the top base 5 and the camera mounted thereon from rotating without external forces. The engagement of the micro-teeth 24 and micro-tooth grooves 21 provides additional stability, ensuring that the camera can be maintained at the set angle.
[0031] In this embodiment, a baffle 25 is fixedly provided at the bottom of the fixed shaft 9, and a support spring 19 is sleeved on the fixed shaft 9 between the baffle 25 and the sleeve 18. This design can generate a reverse elastic force on the fixed shaft 9 through the support spring 19, and can achieve automatic reset after the fixed shaft 9 is adjusted, thereby improving the convenience of operation.
[0032] In this embodiment, a retaining ring 20 is fixed on the annular surface of the cartridge seat 11, and two sets of spaced retaining rings 23 are fixed on the inner annular surface of the top seat 5. When the top seat 5 is clamped onto the cartridge seat 11, the retaining ring 20 is located between the two sets of retaining rings 23. The retaining ring 20 and the retaining ring 23 limit the position of the top seat 5, limiting the range of movement of the top seat 5 on the cartridge seat 11. When the top seat 5 is clamped onto the cartridge seat 11, the retaining ring 20 is located between the two sets of retaining rings 23, thereby ensuring that the top seat 5 does not fall off the cartridge seat 11.
[0033] In this embodiment, an incomplete gear ring 8 is vertically disposed on the annular surface of the hemispherical seat 7. A guide plate 12 is fixedly disposed on the right side of the interior of the square tube bracket 3. A push rod 14 extends through the interior of the guide plate 12. A latch 17, which is compatible with the incomplete gear ring 8, is fixedly connected to the right end of the push rod 14. The latch 17 extends from the right end of the square tube bracket 3 and the interior of the connecting frame 6. A pull rod handle 15 is fixedly disposed on the underside of the annular surface of the push rod 14. A slide groove 16 is defined on the bottom surface of the square tube bracket 3, and the lower end of the pull rod handle 15 extends from the slide groove 16. The incomplete gear ring 8 on the hemispherical seat 7 cooperates with the design of the latch 17, pull rod handle 15, and slide groove 16 on the square tube bracket 3, providing a stable locking mechanism and convenient adjustment method, facilitating locking the rotation angle of the hemispherical seat 7, thereby ensuring the stability of the surveillance camera and greatly improving the practicality and flexibility of the device.
[0034] In this embodiment, a return spring 13 is mounted on the push rod 14 between the pull rod handle 15 and the guide plate 12. The presence of the return spring 13 enables the push rod 14 to automatically return to its original position when no external force is applied. When the user completes the camera angle adjustment and releases the pull rod handle 15, the push rod 14 automatically returns to its original position, and the latching teeth 17 engage with the incomplete ring gear 8 to maintain the locked state. The user no longer needs to manually return the push rod 14, greatly improving adjustment efficiency and operational convenience.
[0035] In this embodiment, a mounting base 4 is fixed to the top of the top base 5. Its primary function is to serve as a supporting platform for the camera. Through the stable mounting base 4, the camera can be securely mounted on the fixture, ensuring that it will not shake or fall off during monitoring, thus facilitating the camera's installation and fixation. The annular surface of the top base 5 is provided with multiple sets of arc-shaped anti-slip grooves 22. The primary function of the anti-slip grooves 22 is to increase the friction between the top base 5 and the contact surface with the hand, helping the user to better grip the top base 5 when adjusting the camera angle and preventing adjustment errors due to hand slippage.
[0036] The working principle of this large-angle traffic monitoring camera fixing device is as follows: First, the device is mounted on the external pillar using the U-shaped bolt 1 in conjunction with the fixing base 2, and then the traffic monitoring camera is mounted on the mounting base 4 on top of the top base 5. However, if the traffic monitoring camera needs to be adjusted horizontally, the top base 5 is held and pulled upward to separate the micro-teeth 24 on the fixing shaft 9 from the micro-teeth 21 inside the shaft sleeve 18, and then the top base 5 is rotated to adjust the traffic monitoring camera to the appropriate angle. If the traffic monitoring camera needs to be adjusted vertically, the pull rod handle 15 is held and pulled to the left, driving the push rod 14 and the latching tooth 17 to move to the left, separating the latching tooth 17 from the incomplete gear ring 8 on the hemispherical seat 7, and then the hemispherical seat 7 is rotated to adjust the traffic monitoring camera to the appropriate angle. After releasing the pull rod handle 15, the reset spring 13 automatically resets the push rod 14, and the latching tooth 17 re-engages with the incomplete gear ring 8, thereby locking the position of the hemispherical seat 7.
[0037] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
