Description

Technical Field

[0001] This utility model relates to the field of motor vehicle inspection technology, and in particular to a limiting device for a motor vehicle inspection platform. Background Technology

[0002] The limiting device for motor vehicle inspection bench is a key device to ensure that the position of a motor vehicle is stable and does not shift or shake when the vehicle is being tested on the inspection bench. It is directly related to the accuracy of the test data and the safety of operation. Therefore, a limiting device for motor vehicle inspection bench is used.

[0003] To address this, patent CN221173882U discloses a limiting device for a motor vehicle inspection platform, relating to the field of motor vehicle inspection platforms. The device includes an inspection platform body, with receiving grooves on both sides of the top of the inspection platform body. A lifting platform is slidably connected to the inner cavity of the receiving grooves. Limiting plates are provided at both the front and rear ends of the top of the lifting platform, with the bottom of the rear limiting plate fixedly connected to the top of the lifting platform. This invention uses a lifting platform to support the vehicle. Since the lifting platform can be raised and lowered, it can lift the vehicle for inspection. The limiting plates are used to limit the vehicle, preventing it from slipping on the top of the lifting platform. Furthermore, because the rear limiting plate is fixedly connected to the top of the lifting platform, and the front limiting plate is slidably connected to the top of the lifting platform, the distance between the two limiting plates can be adjusted by adjusting the position of the front limiting plate, thus making the device suitable for different types of vehicles and achieving practicality.

[0004] Although the aforementioned vehicle inspection platform limiting device can adjust the distance between the two limiting plates by adjusting the position of the front limiting plate, thus making the device applicable to different types of vehicles, its applicability is low because it is inconvenient to fix and prevent the wheels from slipping laterally. Utility Model Content

[0005] The purpose of this utility model is to provide a limiting device for motor vehicle inspection benches, so as to solve the defect of existing limiting devices for motor vehicle inspection benches being inconvenient to fix.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a limiting device for a motor vehicle inspection platform, comprising an inspection platform body;

[0007] A fixing frame is fixed to the outer side of one end of the inspection table body, and a limiting structure is fixed to the end of the inspection table body away from the fixing frame.

[0008] The top of the fixing frame is provided with a fixing structure;

[0009] The fixing structure includes a threaded rod disposed on one side of the top of the fixing frame. The outer sides of both ends of the threaded rod are threadedly connected to movable seats. The bottom end of each movable seat is fixed with a connecting seat. The bottom end of each connecting seat is fixed with a clamping seat. A sliding rod passes through one side of the interior of each movable seat. A servo motor is installed on the outer wall of the fixing frame at one end of the threaded rod.

[0010] When using this device, the fixed structure enables it to prevent lateral slippage, thereby improving its applicability. The limiting structure also enables it to limit different vehicles, thus improving its stability during use.

[0011] Preferably, one end of the threaded rod extends to the outside of the fixed frame and is fixedly connected to the output end of the servo motor, and the thread directions at both ends of the threaded rod are opposite.

[0012] Preferably, the clamping seat has an "L"-shaped cross-section when viewed from above, and an anti-slip pad is fixed to the inner side of the clamping seat. Because the threads at both ends of the threaded rod are in opposite directions, the threaded rod will drive the moving seats at both ends to move in opposite directions. Under the action of the sliding rod, the moving seats are prevented from rotating along with the threaded rod.

[0013] Preferably, the slide rod and the movable seat form a sliding structure, and both ends of the slide rod are fixedly connected to the inner wall of the fixed frame. The moved movable seat drives the clamping seat to move, and the clamping seat causes the anti-slip pad to contact the outer side of the wheel. Under the action of the anti-slip pad, the friction between the clamping seat and the wheel is increased. The clamping seat prevents the wheel from moving forward and also prevents lateral slippage, thereby ensuring the accuracy of the inspection data.

[0014] Preferably, the limiting structure includes a support plate, an electric push rod, a guide rod, a limiting frame, a threaded column, a clamping plate, a movable rod, and a handle. The support plate is fixed to one end of the inspection table body. An electric push rod passes through the top of the support plate. A limiting frame is fixed to one end of the electric push rod. Guide rods pass through the interior of the support plates on both sides of the electric push rod. Threaded columns pass through the interior of both sides of the limiting frame. A clamping plate is rotatably connected to one end of each threaded column. A handle is fixed to the other end of each threaded column. Movable rods pass through the interior of the limiting frames on both sides of the threaded column.

[0015] Preferably, the guide rod and the support plate form a sliding structure. One end of the guide rod is fixedly connected to one side of the limiting frame, and a first rubber pad is fixed to one side of the limiting frame. Under the action of the guide rod, the stability of the limiting frame during movement is enhanced. After movement, the limiting frame causes the first rubber pad to abut against one end of the wheel. Under the action of the first rubber pad, the friction between the limiting frame and the wheel is increased, preventing the wheel from moving backward.

[0016] Preferably, the threaded column and the limiting frame are threadedly connected, a second rubber pad is fixed to one side of the clamping plate, and the movable rod and the limiting frame form a sliding structure. One end of the movable rod is fixedly connected to one side of the clamping plate. Under the action of the movable rod, the stability of the clamping plate during movement is enhanced. After the clamping plate moves, it causes the second rubber pad to come into contact with one side of the wheel. Under the action of the second rubber pad, the friction between the clamping plate and the wheel is increased, preventing the wheel from slipping laterally.

[0017] The limiting device for a motor vehicle inspection platform provided by this utility model has the following advantages:

[0018] By setting a fixed structure, and with the threads at both ends of the threaded rod in opposite directions, the threaded rod will drive the moving seats at both ends to move in opposite directions. Under the action of the sliding rod, the moving seats are prevented from rotating with the threaded rod. After moving, the moving seats drive the clamping seats to move, and the clamping seats drive the anti-slip pad to abut against the outside of the wheel. Under the action of the anti-slip pad, the friction between the clamping seats and the wheel is increased. Under the action of the clamping seats, the wheel is prevented from moving forward and from sliding laterally, thereby ensuring the accuracy of the inspection data. This device realizes the function of preventing lateral slippage, thereby improving the applicability of the limit device for motor vehicle inspection bench in use.

[0019] By setting a limiting structure, the stability of the limiting frame during movement is enhanced under the action of the guide rod. After movement, the limiting frame causes the first rubber pad to abut against one end of the wheel. Under the action of the first rubber pad, the friction between the limiting frame and the wheel is increased, preventing the wheel from moving backward. Under the action of the movable rod, the stability of the clamping plate during movement is enhanced. After movement, the clamping plate causes the second rubber pad to abut against one side of the wheel. Under the action of the second rubber pad, the friction between the clamping plate and the wheel is increased, preventing the wheel from sliding laterally. This device realizes the function of limiting different vehicles, thereby improving the stability of the limiting device for motor vehicle inspection bench during use. Attached Figure Description

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.

[0027] Please see Figures 1-5 This utility model provides a limiting device for a motor vehicle inspection platform, including an inspection platform body 1. A fixing frame 2 is fixed to the outer side of one end of the inspection platform body 1. A limiting structure 4 is fixed to the end of the inspection platform body 1 away from the fixing frame 2. The limiting structure 4 includes a support plate 401, an electric push rod 402, a guide rod 403, a limiting frame 404, a threaded post 405, a clamping plate 406, a movable rod 407, and a handle 408. The support plate 401 is fixed to one end of the inspection platform body 1. The electric push rod 402 passes through the top of the support plate 401. The limiting frame 404 is fixed to one end of the electric push rod 402. Guide rods 403 pass through the interior of the support plates 401 on both sides of the electric push rod 402. The limiting frame 404... 4. Threaded posts 405 penetrate both sides of the interior. One end of each threaded post 405 is rotatably connected to a clamping plate 406. The other end of each threaded post 405 is fixed with a handle 408. Movable rods 407 penetrate both sides of the limiting frame 404. Guide rod 403 and support plate 401 form a sliding structure. One end of guide rod 403 is fixedly connected to one side of limiting frame 404. A first rubber pad is fixed to one side of limiting frame 404. Threaded posts 405 and limiting frame 404 are threadedly connected. A second rubber pad is fixed to one side of clamping plate 406. Movable rod 407 and limiting frame 404 form a sliding structure. One end of movable rod 407 is fixedly connected to one side of clamping plate 406.

[0028] Reference Figure 4 and Figure 5As shown, when the electric push rod 402 is activated, it drives the limiting frame 404 to move. The limiting frame 404 drives the guide rod 403 to move inside the support plate 401. Under the action of the guide rod 403, the stability of the limiting frame 404 during movement is enhanced. After moving, the limiting frame 404 causes the first rubber pad to abut against one end of the wheel. Under the action of the first rubber pad, the friction between the limiting frame 404 and the wheel is increased, preventing the wheel from moving backward. When the handle 408 is turned, the handle 408 drives the threaded column 405 to rotate inside the limiting frame 404. The threaded column 405 drives the clamping plate 406 to move. At the same time, the clamping plate 406 drives the movable rod 407 to move inside the limiting frame 404. Under the action of the movable rod 407, the stability of the clamping plate 406 during movement is enhanced. After moving, the clamping plate 406 causes the second rubber pad to abut against one side of the wheel. Under the action of the second rubber pad, the friction between the clamping plate 406 and the wheel is increased, preventing the wheel from slipping laterally.

[0029] The top of the fixed frame 2 is provided with a fixed structure 3. The fixed structure 3 includes a threaded rod 301 set on one side of the top of the fixed frame 2. The outer sides of both ends of the threaded rod 301 are threadedly connected to the movable seats 302. The bottom end of the movable seats 302 is fixed with the connecting seats 304. The bottom end of the connecting seats 304 is fixed with the clamping seats 303. A sliding rod 305 passes through one side of the interior of the movable seats 302. A servo motor 306 is installed on the outer wall of the fixed frame 2 at one end of the threaded rod 301. One end of the threaded rod 301 extends to the outside of the fixed frame 2 and is fixedly connected to the output end of the servo motor 306. The thread directions at both ends of the threaded rod 301 are opposite. The top view of the clamping seat 303 is an "L" shaped design. An anti-slip pad is fixed on the inner side of the clamping seat 303. The sliding rod 305 and the movable seats 302 form a sliding structure. Both ends of the sliding rod 305 are fixedly connected to the inner wall of the fixed frame 2.

[0030] Reference Figure 2 and Figure 3 As shown, when the servo motor 306 is started, it drives the threaded rod 301 to rotate. Since the threads at both ends of the threaded rod 301 are in opposite directions, the threaded rod 301 will drive the moving seats 302 at both ends to move in the opposite direction. The moving seats 302 will move outside the slide rod 305. Under the action of the slide rod 305, the moving seats 302 are prevented from rotating with the threaded rod 301. After moving, the moving seats 302 drive the clamping seat 303 to move through the connecting seat 304, so that the clamping seat 303 drives the anti-slip pad to abut against the outside of the wheel. Under the action of the anti-slip pad, the friction between the clamping seat 303 and the wheel is increased. Under the action of the clamping seat 303, the wheel is prevented from moving forward and from sliding laterally, thereby ensuring the accuracy of the inspection data.
