[0002] Public buses are the most common form of public transportation. Urbanization and motorization have led to a continuous increase in urban population and area, resulting in a rapid increase in demand for public transportation and requiring public transportation companies to invest in more buses. Based on the statistic of 0.6 buses per 10,000 urban residents, there are currently approximately 264,000 urban buses, and this number is expected to reach at least 630,000 by 2010, averaging at least 30,000 to 40,000 buses per year. Including replacements and scrapping, this translates to an average annual increase of 55,000 buses. Public buses are primarily designed to meet the commuting needs of people in rural areas, offering affordable and convenient transportation options for working professionals.

[0003] No effective solutions have yet been proposed to address the problems in the relevant technologies.

[0004] 1. Existing adjustable bus cameras cannot be properly adjusted during use, and because buses are prone to bumps, the cameras cannot be stably fixed, resulting in less than ideal image quality and affecting normal use. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes an adjustable bus camera to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0018] Using the above technical solution, the reset spring in the solution can drive the movable block to drive the L-shaped fixed block to perform a reset movement, thereby making the L-shaped fixed block snap into the inside of the fixed groove.

[0019] A further improvement of the present invention is that: the upper and lower ends of the movable block are fixedly connected to limit blocks, the upper and lower inner walls of the slide groove are provided with limit grooves, the limit block is slidably connected to the inside of the limit groove, the reset spring is fixedly connected to one end of the limit block, and the end of the reset spring away from the limit block is fixedly connected to the inner wall of the limit groove.

[0020] Using the above technical solution, the limiting block and limiting groove in the solution can limit the movement of the moving block, so that the moving block will not fall off the slide.

[0021] The beneficial effects of this utility model are as follows:

[0022] 1. The left and right angles of the camera body can be adjusted by rotating the support frame. Rotating the fastening bolts causes them to move downwards, resulting in friction between the first and second inclined surfaces.

[0035] In this embodiment, the angle of the camera body 4 can be adjusted by rotating the support frame 3, and the fastening bolt 2 can be rotated to move it downward, so that the first inclined surface 106 and the second inclined surface 202 rub against each other, and the plastic buckles 105 move closer to each other under the pressure of friction to clamp and fix the support frame 3, providing good stability for the camera body 4, and thus ensuring good monitoring image quality.

[0036] Example 2;

[0037] like Figure 1-4As shown, in the adjustable bus camera according to an embodiment of the present invention, the bottom of the movable slot 101 is provided with a slot 102, which is adapted to the support frame 3. The support frame 3 is rotatably connected to the inside of the slot 102. The slot 102 is located at the center of the plastic buckles 105 arranged in a circumferential array. The inside of the fastening bolt 2 is provided with a through slot 201, which is adapted to the support frame 3. The positions of the through slot 201 and the slot 102 are adapted to each other.

[0038] In this embodiment, the support frame 3 is rotatably connected to the inside of the support base 1 through the slot 102. The limiting block 301 and the limiting slot 103 can limit the support frame 3 so that the support frame 3 will not detach from the support base 1.

[0039] Example 3;

[0040] like Figure 1-4 As shown, in the adjustable bus camera according to this embodiment of the utility model, the upper end of the inner wall of the movable groove 101 is provided with a threaded pattern 104, which is adapted to the fastening bolt 2. The fastening bolt 2 is threadedly engaged with the upper end of the support base 1 through the threaded pattern 104. The two sides of the upper end of the support frame 3 are fixedly connected with rotating shafts 302. The bottom of the camera body 4 is fixedly connected with a connecting block 401. The two sides of the connecting block 401 are provided with rotating grooves 402. The rotating shaft 302 is rotatably connected to the inside of the rotating groove 402. The rotating shaft 302 on one side of the upper end of the support frame 3 is provided with a sliding groove, and the movable block 30 is slidably connected inside the sliding groove. 4. The upper and lower ends of the movable block 304 are provided with return springs 306. One end of the movable block 304 is fixedly connected to an L-shaped fixing block 307. A fixing groove 403 is formed in a circular array on one side of the connecting block 401. One end of the L-shaped fixing block 307 is fixedly connected to a pull rod 308.

The limiting block 305 and the limiting groove 303 can limit the movable block 304, so that the movable block 304 will not fall off the slide groove.

[0042] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0043] In practical applications, the left and right angles of the camera body 4 can be adjusted by rotating the support frame 3. After adjustment, the fastening bolt 2 can be rotated to move downwards under the action of the thread 104, so that the first inclined surface 106 and the second inclined surface 202 rub against each other. This causes the plastic buckles 105 to come closer together under the pressure of friction, clamping and fixing the support frame 3. When it is necessary to adjust the up and down angle of the camera body 4, pulling the lever 308 can drive the L-shaped fixing block 307 out of the fixing groove 403 and compress the return spring 306. Then, the camera body 4 can be bent to rotate it around the pivot 302, thereby adjusting the up and down angle of the camera body 4. After adjustment, releasing the lever 308 and the return spring 306 can drive the movable block 304 to drive the L-shaped fixing block 307 to perform a reset movement, so that the L-shaped fixing block 307 is engaged inside the fixing groove 403, thereby adjusting and fixing the camera body 4.
