Description

Technical Field

[0001] This utility model relates to the field of camera mounting bracket technology, and in particular to a tunnel camera mounting bracket that is easy to maintain. Background Technology

[0002] Existing highway and expressway tunnel monitoring equipment is installed using fixed brackets. Traditional tunnel cameras are installed 4.5 meters high on the inner wall of the tunnel. Due to the limited space inside the tunnel, every time staff need to repair and wipe the camera, the road must be closed and an aerial work platform must be used to lift the staff to the corresponding height before the camera maintenance work can be carried out. This results in cumbersome, time-consuming and inefficient camera maintenance procedures inside the tunnel.

[0003] A search revealed a Chinese patent application with patent number CN202021847074.6, which discloses a tunnel wall-mounted camera lifting device, including a fixing plate with fixing holes and a rotating disk inside the fixing plate. However, the above technical solution lacks a mechanism to allow the camera to be easily moved to near ground level, resulting in low camera maintenance efficiency because it cannot be easily moved to near ground level for maintenance without affecting vehicle traffic in the tunnel. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a convenient tunnel camera mounting bracket for maintenance.

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

[0006] A convenient tunnel camera mounting bracket includes a mounting plate. A support frame and a fixing frame are fixed to one outer wall of the mounting plate. A connecting frame is bolted to the outer wall of the support frame. A mounting frame is bolted to the inner wall of the connecting frame. A support tube is fixed to the top outer wall of the mounting frame. An arc-shaped support rod is rotatably connected to the top outer wall of the support tube.

[0007] The top of the arc-shaped support rod is fixed with an installation plate, and a set of second fixing plates are slidably connected to the outer wall of the arc-shaped support rod. A first fixing plate is fixed to one side of the outer wall of the second fixing plate. The first fixing plate and the outer wall of the fixing frame on opposite sides are respectively opened with a first round hole. The first fixing plate is fixed to one side of the outer wall of the fixing frame by bolts.

[0008] As a further improvement of this utility model: the outer walls of the support frame and the connecting frame on opposite sides are respectively provided with a third circular hole, and the outer walls of the connecting frame and the mounting frame on opposite sides are respectively provided with a fourth circular hole.

[0009] As a further embodiment of this utility model: the outer wall of the arc-shaped support rod is fitted with a limiting piece, the outer wall of the limiting piece has an arc-shaped groove, and the arc-shaped support rod is slidably connected to the inner wall of the arc-shaped groove.

[0010] As a further improvement of this utility model, an mounting plate is fixed to one side of the outer wall of the limiting plate.

[0011] As a further improvement of this utility model: a first connecting ring is fixed to the outer wall of the bottom end of the arc-shaped support rod, and a second connecting ring is fixed to the outer wall of the top end of the support tube.

[0012] As a further improvement of this utility model: the outer wall of the second connecting ring has a set of arc-shaped limiting grooves, and the outer wall of the first connecting ring has a set of second circular holes.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. Workers only need to remove the bolts fixed between the first fixing plate and the fixing frame to release the support and fixation of the entire arc-shaped support rod. Then, loosen the corresponding nuts on the outer wall of the bolts between the connecting frame and the support frame, as well as between the mounting frame and the connecting frame. This allows the arc-shaped support rod to rotate up, down, left, and right under the support of the mounting frame and the connecting frame, so that the camera fixed at the top of the arc-shaped support rod can be rotated directly to a position close to the ground on one side of the mounting plate, making it convenient for workers to maintain the camera.

[0015] 2. The workers fix the mounting plate to the arc-shaped surface of the inner wall of the tunnel top with screws. Then, by rotating the arc-shaped support rod connected to the top of the support pipe, the arc-shaped support rod is rotated and snapped into the arc-shaped slot on the inner wall of the limiting plate, thereby clamping and limiting the upper part of the arc-shaped support rod. Together with the second fixing plate and the first fixing plate on the lower part of the arc-shaped support rod, the arc-shaped support rod provides stable limiting support, improving the stable support effect of the arc-shaped support rod for the camera.

[0016] 3. The bolt passes through the second round hole and the arc-shaped limiting groove on one side of the first connecting ring and the second connecting ring, connecting the first connecting ring and the second connecting ring together. When the arc-shaped support rod rotates at the top of the support tube, the bolt connected between the second round hole and the arc-shaped limiting groove will slide inside the arc-shaped limiting groove, thereby limiting the rotation angle of the arc-shaped support rod and improving the stability of the connection between the support tube and the arc-shaped support rod.

Detailed Implementation

[0023] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0024] The embodiments of this patent are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this patent, and should not be construed as limiting this patent.

[0025] Example 1: A convenient tunnel camera mounting bracket for maintenance, such as... Figure 1-5 As shown, it includes a mounting plate 1. A support frame 10 and a fixing frame 7 are fixed to one side of the outer wall of the mounting plate 1. A connecting frame 2 is bolted to the outer wall of the support frame 10. A mounting frame 11 is bolted to the inner wall of the connecting frame 2. A support tube 20 is fixed to the top outer wall of the mounting frame 11. An arc-shaped support rod 3 is rotatably connected to the top outer wall of the support tube 20.

[0026] The top of the arc-shaped support rod 3 is fixed with a mounting plate 6. A set of second fixing plates 12 are slidably connected to the outer wall of the arc-shaped support rod 3. A first fixing plate 9 is fixed to one side of the outer wall of the second fixing plate 12. The first fixing plate 9 and the outer wall of the fixing frame 7 on opposite sides are respectively provided with first round holes 13. The first fixing plate 9 is fixed to one side of the outer wall of the fixing frame 7 by bolts.

[0027] The bolts fix the first fixing plate 9 and the fixing frame 7 together through the first round hole 13 on the outer wall of the opposite side of the first fixing plate 9 and the fixing frame 7, thereby supporting and fixing the arc-shaped support rod 3 connected inside the second fixing plate 12 as a whole. The workers only need to remove the bolts fixed between the first fixing plate 9 and the fixing frame 7 to release the support and fixation of the arc-shaped support rod 3 as a whole.

[0028] The outer walls of the support frame 10 and the connecting frame 2 on opposite sides are respectively provided with a third circular hole 18, and the outer walls of the connecting frame 2 and the mounting frame 11 on opposite sides are respectively provided with a fourth circular hole 19. Bolts pass through the third circular hole 18 on one side of the connecting frame 2 and the support frame 10 to connect the connecting frame 2 and the support frame 10 together. Bolts pass through the fourth circular hole 19 on one side of the mounting frame 11 and the connecting frame 2 to connect the mounting frame 11 to the inner wall of the connecting frame 2. The operator only needs to loosen the corresponding nut on the outer wall of the bolt to push the arc-shaped support rod 3 to rotate up, down, left, and right under the support of the mounting frame 11 and the connecting frame 2, so that the camera fixed at the top of the arc-shaped support rod 3 can be directly rotated to a position close to the ground on one side of the mounting plate 1, which makes it convenient for the operator to maintain the camera.

[0029] In this embodiment, the mounting plate 1 is fixed to the inner wall of the tunnel at a distance of 1.8 meters from the road surface by screws, and the length of the arc-shaped support rod 3 is greater than 2.7 meters. At this time, the top of the arc-shaped support rod 3 after being erected is more than 4.5 meters above the road surface, which meets the requirement that traditional tunnel cameras need to be installed at a height of more than 4.5 meters on the tunnel wall.

[0030] like Figure 3 As shown, the outer wall of the arc-shaped support rod 3 is fitted with a limiting piece 4, and the outer wall of the limiting piece 4 has an arc-shaped groove 8. The arc-shaped support rod 3 is slidably connected to the inner wall of the arc-shaped groove 8.

[0031] An mounting plate 5 is fixed to one side of the outer wall of the limiting plate 4. The operator fixes the mounting plate 5 to the arc surface of the inner wall of the tunnel top with screws. Then, by rotating the arc-shaped support rod 3 connected to the top of the support tube 20, the arc-shaped support rod 3 is rotated and inserted into the arc-shaped slot 8 on the inner wall of the limiting plate 4, thereby clamping and limiting the upper part of the arc-shaped support rod 3. Together with the second fixing plate 12 and the first fixing plate 9 of the lower part of the arc-shaped support rod 3, the arc-shaped support rod 3 is stably limited and supported, improving the stable support effect of the arc-shaped support rod 3 for the camera.

[0032] like Figure 5 As shown, a first connecting ring 14 is fixed to the outer wall of the bottom end of the arc-shaped support rod 3, and a second connecting ring 17 is fixed to the outer wall of the top end of the support tube 20.

[0033] The outer wall of the second connecting ring 17 has a set of arc-shaped limiting grooves 16, and the outer wall of the first connecting ring 14 has a set of second round holes 15. The bolt passes through the second round hole 15 and the arc-shaped limiting groove 16 on one side of the first connecting ring 14 and the second connecting ring 17, connecting the first connecting ring 14 and the second connecting ring 17 together. When the arc-shaped support rod 3 rotates at the top of the support tube 20, the bolt connected between the second round hole 15 and the arc-shaped limiting groove 16 will slide inside the arc-shaped limiting groove 16, thereby limiting the rotation angle of the arc-shaped support rod 3 and improving the stability of the connection between the support tube 20 and the arc-shaped support rod 3.

[0034] Working principle: The bolts fix the first fixing plate 9 and the fixing frame 7 together through the first round hole 13 on the outer wall of the opposite side of the first fixing plate 9 and the fixing frame 7, thus supporting and fixing the arc-shaped support rod 3 connected inside the second fixing plate 12. Simply remove the bolts fixed between the first fixing plate 9 and the fixing frame 7 to release the support and fixation of the arc-shaped support rod 3. The bolts pass through the third round hole 18 on the side of the connecting frame 2 and the support frame 10, connecting the connecting frame 2 and the support frame 10 together. The bolts pass through the fourth round hole 19 on the side of the mounting frame 11 and the connecting frame 2, connecting the mounting frame 11 to the inner wall of the connecting frame 2. Simply loosen the corresponding nut on the outer wall of the bolts to push the arc-shaped support rod 3 to rotate up, down, left, and right under the support of the mounting frame 11 and the connecting frame 2, allowing the camera fixed at the top of the arc-shaped support rod 3 to rotate directly to the side of the mounting plate 1 near the ground, thus facilitating the maintenance of the camera by the staff.

[0035] The mounting plate 5 is fixed to the arc surface of the inner wall of the tunnel top with screws. Then, the arc-shaped support rod 3 connected to the top of the support pipe 20 is rotated and inserted into the arc-shaped slot 8 on the inner wall of the limiting plate 4, thereby clamping and limiting the upper part of the arc-shaped support rod 3. The second fixing plate 12 and the first fixing plate 9 of the lower part of the arc-shaped support rod 3 provide stable limiting support for the arc-shaped support rod 3.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
