These systems include cameras for capturing real-time scenes at railway crossings, wireless video transmission devices, and video receiving and displaying devices on trains, which play a role in improving transportation safety, assisting law enforcement, and enhancing work efficiency. To sum up, the problems existing in the prior art are as follows: A monitoring camera is a device for capturing and transmitting video images. When in use, the monitoring camera needs to be installed at the position of the railway crossing through bolts. The monitoring camera is exposed to the outdoor for a long time and is easily affected by environments such as high temperature and high pressure, which is prone to corrosion or damage and needs to be replaced regularly. When replacing, a supporting auxiliary tool needs to be used to continuously adjust multiple bolts, which increases the replacement time and difficulty. Moreover, the bolts are prone to corrosion and aging after long-term use, resulting in difficult disassembly of the bolts. However, the monitoring cameras used at existing railway crossings do not have components for convenient replacement. Therefore, a camera recording device for railway intersections is specifically proposed to solve the above problems. Summary of the Utility Model

When in use, the monitoring camera needs to be installed at the position of the railway crossing through bolts. The monitoring camera is exposed to the outdoor for a long time and is easily affected by environments such as high temperature and high pressure, which is prone to corrosion or damage and needs to be replaced regularly. When replacing, a supporting auxiliary tool needs to be used to continuously adjust multiple bolts, which increases the replacement time and difficulty. Moreover, the bolts are prone to corrosion and aging after long-term use, resulting in difficult disassembly of the bolts. However, the monitoring cameras used at existing railway crossings do not have components for convenient replacement.

[0004] The utility model is realized as follows: A camera recording device for railway intersections includes a monitoring camera and a device housing. The rear side of the monitoring camera is fixedly connected to the front side of the device housing. The rear side of the device housing is movably connected to an installation base, and the installation base is arranged on the wall.

[0005] Preferably, the limiting structure of the present utility model includes two limiting blocks. One side of the two limiting blocks opposite to each other penetrates through the device housing and extends to the outside of the inner cavity of the device housing. A moving hole is formed on the surface of the limiting block. Two moving blocks cooperating with the moving hole are fixedly connected to the rear side of the inner cavity of the device housing. The surface of the moving block is movably connected to the inner cavity of the moving hole. A spring is fixedly connected to one side of the two moving blocks opposite to each other. The side of the spring close to the inner cavity of the moving hole is fixedly connected to the inner cavity of the moving hole. By providing the limiting structure, when the device housing and the monitoring camera move to a suitable position, the limiting structure has a limiting effect on the positions of the device housing and the monitoring camera.

[0006] Preferably, a gear ring is movably connected to one side of the inner cavity of the device housing close to the limiting block. The surface of the gear ring is fixedly connected to the surface of the control rod. By providing the gear ring, when the control rod rotates, it will drive the gear ring to rotate along the surface of the rotating gear disc.

The surface of the limiting block is in contact with the inner cavity of the limiting groove. By providing the limiting groove, when the device housing moves to the surface of the mounting base and the control rod is released, the restoring force generated by the spring restoring its shape will drive the limiting block to snap into the inner cavity of the limiting groove.

By using the cooperation of the limit structure, moving holes, moving blocks, springs and limit grooves, the present utility model solves the problem that existing monitoring cameras are devices for capturing and transmitting video images. When in use, the monitoring cameras need to be installed at the railway crossing through bolts. The monitoring cameras are long-term exposed to the outdoor environment and are easily affected by high temperature, high pressure and other environments, which is prone to corrosion or damage and needs to be replaced regularly. When replacing, it is necessary to use supporting auxiliary tools to continuously adjust multiple bolts, which increases the replacement time and difficulty.

The limit structure has a limiting effect on the positions of the device housing and the monitoring camera. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to further understand the invention content, features and effects of the present utility model, the following embodiments are cited and detailed as follows in conjunction with the accompanying drawings.

[0020] The structure of the present utility model will be described in detail below with reference to the accompanying drawings.

[0021] As shown Figures 1 to 4 in the figure, a camera recording device for a railway crossing provided by an embodiment of the present utility model includes a monitoring camera 1 and a device housing 2. The rear side of the monitoring camera 1 is fixedly connected to the front side of the device housing 2. The rear side of the device housing 2 is movably connected to a mounting base 3, and the mounting base 3 is arranged on the wall. Two control rods 4 are movably connected to the inner cavity of the device housing 2, and a limiting structure 5 is arranged inside the device housing 2.

[0022] Referring Figure 4 to the figure, the limiting structure 5 includes two limiting blocks 501. The opposite sides of the two limiting blocks 501 penetrate through the device housing 2 and extend to the outside of the inner cavity of the device housing 2. A moving hole 502 is formed on the surface of the limiting block 501. Two moving blocks 503 that cooperate with the moving hole 502 are fixedly connected to the rear side of the inner cavity of the device housing 2. The surface of the moving block 503 is movably connected to the inner cavity of the moving hole 502. A spring 504 is fixedly connected to the opposite sides of the two moving blocks 503, and the side of the spring 504 close to the inner cavity of the moving hole 502 is fixedly connected to the inner cavity of the moving hole 502.

[0023] With the above solution: By setting the limiting structure 5, when the device housing 2 and the monitoring camera 1 are moved to a suitable position, the limiting structure 5 has a limiting effect on the positions of the device housing 2 and the monitoring camera 1.

[0024] Referring Figure 3 to the figure, a gear ring 6 is movably connected to the side of the inner cavity of the device housing 2 close to the limiting block 501, and the surface of the gear ring 6 is fixedly connected to the surface of the control rod 4.

[0025] With the above solution: By setting the gear ring 6, when the control rod 4 rotates, it will drive the gear ring 6 to rotate along the surface of the rotating gear disk 7. The rotational force generated by the gear ring 6 when rotating can drive the rotating gear disk 7 to rotate through the rotating shaft.

[0026] Referring Figure 3 to the figure, two rotating gear disks 7 that cooperate with the gear ring 6 are movably connected to the rear side of the inner cavity of the device housing 2 through a rotating shaft, and the surface of the rotating gear disk 7 is meshed with the surface of the gear ring 6.

[0027] With the above solution: By setting the rotating gear disk 7, when the rotating gear disk 7 rotates, it can generate a rotational force on the moving rack 8, and the moving rack 8 subjected to the rotational force will move.

[0028] Referring Figure 3 to the figure, moving racks 8 that cooperate with the rotating gear disk 7 are fixedly connected to the opposite sides of the two limiting blocks 501, and the surface of the moving rack 8 is meshed with the surface of the rotating gear disk 7.

[0029] Adopt the above solution: By setting the moving rack 8, when the moving rack 8 moves, it can drive the two limit blocks 501 to move simultaneously.

[0030] Reference Figure 3 , both the left and right sides of the gear ring 6 are fixedly connected with sliders 9, and both the left and right sides of the device housing 2 are fixedly connected with sliding holes 10 that cooperate with the sliders 9. The opposite sides of the two sliders 9 and the control rod 4 pass through the sliding holes 10 and extend to the outside of the inner cavity of the sliding holes 10.

[0031] Adopt the above solution: By setting the sliders 9 and the sliding holes 10, when the gear ring 6 rotates, it can drive the sliders 9 to rotate along the inner cavity of the sliding holes 10. The cooperation between the sliders 9 and the sliding holes 10 has a limiting effect on the rotation position of the gear ring 6.

[0032] Reference Figure 2 , both the left and right sides of the mounting base 3 are provided with limiting grooves 11 that cooperate with the limit blocks 501, and the surface of the limit blocks 501 is in contact with the inner cavity of the limiting grooves 11.

[0033] Adopt the above solution: By setting the limiting grooves 11, when the device housing 2 moves to the surface of the mounting base 3 and the control rod 4 is released, the restoring force generated by the spring 504 restoring its shape will drive the limit blocks 501 to snap into the inner cavity of the limiting grooves 11. The cooperation between the limit blocks 501 and the limiting grooves 11 has a limiting effect on the positions of the device housing 2 and the monitoring camera 1.

[0034] The working principle of the present utility model:

[0035] When in use, when it is necessary to conveniently replace the surveillance camera 1 used at the railway intersection, the operator will first rotate the two control rods 4. When the control rods 4 rotate, the gear ring 6 will be driven to rotate along the surface of the rotating toothed disc 7. When the gear ring 6 rotates, the slider 9 will be driven to rotate along the inner cavity of the sliding hole 10. The rotating toothed disc 7 subjected to the rotational force will rotate along the surface of the moving rack 8 through the rotating shaft. The rotational force generated by the rotating toothed disc 7 on the moving rack 8 will drive the two moving racks 8 to move to the side away from the control rod 4. When the moving rack 8 moves, it will drive the two limit blocks 501 to move to the side away from each other. When the limit block 501 moves, it will drive the moving hole 502 to move along the surface of the moving block 503. When the limit block 501 The force generated during movement causes the spring 504 to undergo elastic deformation. When the limit block 501 is completely disengaged from the limit groove 11 and moves to the inside of the device shell 2, the device shell 2 can be moved to a position where it is out of contact with the mounting base 3. At this time, the surveillance camera 1 is disassembled. Thereafter, the replaced surveillance camera 1 is moved to the front side of the mounting base 3 by rotating the control lever 4. When the surface of the device shell 2 contacts the surface of the mounting base 3, the control lever 4 is released. The restoring force generated by the spring 504 restoring its shape will drive the limit block 501 to be stuck into the inner cavity of the limit groove 11. The coordinated use of the limit block 501 and the limit groove 11 has a limiting effect on the position of the surveillance camera 1 and the device shell 2. At this time, the surveillance camera 1 used at the railway intersection can be easily replaced.

[0036] To sum up: the video recording equipment for railway crossings, by setting a limiting structure 5, a movable hole 502, a movable block 503, a spring 504 and a limiting groove 11 for coordinated use, solves the problem that the existing surveillance camera is a device for capturing and transmitting video images. When in use, the surveillance camera needs to be installed at the position of the railway crossing by bolts. The surveillance camera is exposed to the outdoors for a long time and is easily affected by high temperature and high pressure environments, which is prone to corrosion or damage and needs to be replaced regularly. When replacing, it is necessary to use matching auxiliary tools to continuously adjust multiple bolts, which increases the replacement time and difficulty. In addition, the bolts are prone to corrosion and aging due to long-term use, making it difficult to disassemble the bolts. However, the surveillance cameras used in existing railway crossings do not have components that can be easily replaced.
