[0002] At present, when performing automobile maintenance, it is often necessary to lift the car to facilitate chassis maintenance, tire replacement, oil replacement, etc. Among them, the car lift is a commonly used car lifting equipment. For example, the four-post lift drives the platform up and down through a hydraulic system or an electric system, combined with a solid mechanical structure and a variety of safety devices to ensure the stability and safety of the vehicle during the lifting process.
[0003] A four-column hydraulic lift is disclosed in the Chinese utility model patent with the announcement number CN103738895A. When the lift is used, the car is supported by the main bridge plate and the auxiliary bridge plate. That is, the car tires are directly parked on the main bridge plate and the auxiliary bridge plate, and no other structure is set to fix the car. As the main bridge plate rises and the maintenance work is carried out, the car may still slip. Based on this, the applicant proposes a car maintenance retention device that can fix the car while the car is lifted for maintenance to prevent it from slipping. Utility Model Content
[0004] In order to solve the fixing problem when a car is lifted for maintenance, the utility model provides a car maintenance fixing device.
[0005] The utility model is implemented by the following technical scheme: a vehicle maintenance fixing device, comprising a column, on which are provided:
[0006] A crossbeam, the crossbeam being movably mounted on the column;

[0008] A movable support plate, the movable support plate is movably installed in the positioning opening;
[0009] A flip baffle is rotatably mounted on the main bridge plate.
[0010] Through the above technical solution, the existing four-post lift drives the main bridge plate to move up and down through the cooperation of motors, steel cables, discs and other mechanisms. This is the existing technology. Since the car is mainly placed on the main bridge plate, a positioning hole is set at the corresponding position of the wheel. When the main bridge plate rises, the lower half of the wheel falls into the positioning hole, and the movable support plate supports the wheel from the bottom, and the flip baffle further blocks the wheel to prevent it from moving. It is convenient for maintenance personnel to repair the vehicle.
[0011] As a further improvement of the above solution, the movable support plates are arranged in groups of two, a connecting shaft is provided between the two movable support plates, and the movable support plates are rotatably connected to the connecting shaft.
[0012] As a further improvement of the above scheme, a mounting hole is opened inside the main bridge plate, and a connecting rod is arranged in the mounting hole. One end of the connecting rod extends out of the mounting hole and is connected to the side of the movable support plate. At the same time, a spring is sleeved on the outer side of the connecting rod located inside the mounting hole.
[0013] As a further improvement of the above solution, a mounting opening is provided on the main bridge plate, the flip baffle is rotatably connected in the mounting opening, and climbing plates are fixedly connected to both sides of the main bridge plate.
[0014] As a further improvement of the above solution, an auxiliary connecting rod is rotatably connected to the connecting rod, and the other end of the auxiliary connecting rod extends out of the top of the mounting hole and is rotatably connected to the flip baffle.

[0017] Compared with the prior art, the beneficial effects of the present invention are:
[0018] When the utility model drives the automobile to be lifted upward by the main bridge plate, the automobile tire will be trapped in the positioning opening due to the rotation of the movable support plate, and the automobile cannot continue to move. At the same time, the movable support plate will drive the flip baffle to flip through the cooperation of the connecting rod and the auxiliary connecting rod. The two flip baffles are located between the two tires of the automobile. Therefore, no matter the automobile moves forward or backward, it will be blocked by the flip baffle, which further fixes the automobile and prevents the automobile from slipping during maintenance, thus facilitating maintenance for employees.

[0024] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.
[0025] Please combine Figure 1 - Figure 4 , this embodiment is a car maintenance fixing device, this embodiment adopts a four-post lift type structure, including four pillars 1 and two front and rear beams 3. A motor 4, a fuel tank and a control panel (not marked in the figure) are also installed on the outside of the pillar 1. A slide groove is provided on the inside of the pillar 1, and a slider 2 is slidably installed in the slide groove. The slider 2 is fixedly connected to the beam 3. In addition, it is necessary to provide supporting mechanisms such as steel cables and discs, which mainly rely on four thick steel cables to pull up the four corners and transmit the force to the four sides through six discs. (The above is the structure of an existing four-post lift, not shown in the figure). Finally, the beam 3 is driven to move up and down along the pillar 1.
[0026] A main bridge plate 5 is fixedly connected to the cross beam 3, and the main bridge plate 5 is used to carry and fix the car. In order to facilitate the car to drive onto the main bridge plate 5, climbing plates 14 are fixedly connected to both ends of the main bridge plate 5. In addition, four positioning holes 6 are opened on the main bridge plate 5. The positioning holes 6 are provided with movable support plates 10, wherein the movable support plates 10 are grouped in pairs, and a connecting shaft 11 is provided between the two movable support plates 10, and the two movable support plates 10 are rotatably connected to each other through the connecting shaft 11.
[0027] In addition, a mounting hole 7 is provided inside the main bridge plate 5, and a connecting rod 8 is provided inside the mounting hole 7. One end of the connecting rod 8 extends out of the mounting hole 7 and is rotatably connected to the other end of the above-mentioned movable support plate 10. The other ends of the two movable support plates 10 are connected to the connecting rod 8. In addition, a cylindrical blocking block (not marked in the figure) is provided at the exit of the mounting hole 7, and a limiting block (not marked in the figure) is connected to the end of the connecting rod 8. The connecting rod 8 can pass through the blocking block, but the limiting block will be blocked. In addition, a spring 9 is sleeved on the outer side of the connecting rod 8 located inside the mounting hole 7.
[0028] In summary, in the initial state, the spring 9 pushes the connecting rod 8 to retract into the mounting hole 7. At this time, the two movable support plates 10 in the positioning opening 6 are in a horizontal state, and their upper end surfaces are flush with the upper end surface of the main bridge plate 5, which will not affect the driving of the car. The car drives along the main bridge plate 5. When the wheel is at the position of the positioning opening 6, the two movable support plates 10 are located below the car tires. At this time, if the control beam 3 is lifted, the main bridge plate 5 moves upward together.
[0029] At the initial stage of the main bridge plate 5 rising, only the main bridge plate 5 is lifted upward, and at this time, the movable support plate 10 is in contact with the car. The car does not rise. When the main bridge plate 5 continues to rise and the bridge deck of the main bridge plate 5 contacts the bottom of the car, the main bridge plate 5 will drive the car to move upward. The two movable support plates 10 also change from a horizontal state to an inclined "V" shape, the connecting rod 8 is partially pulled out of the mounting hole 7, and the spring 9 is compressed.
[0030] At this time, the bottom of the car is supported by the main bridge plate 5, and a large blank area is provided in the middle of the main bridge plate 5, which is convenient for inspection and maintenance of the car from the bottom. The movable support plate 10 is in a "V" shape, and the lower half of the car tire is located in the positioning port 6. That is, the traditional four-post lift directly lifts the car by the wheels, and the main bridge plate 5 directly lifts the car, and the car tire is "trapped" in the positioning port 6. Therefore, the car can be fixed and cannot be moved. It is convenient for employees to carry out maintenance.
[0031] In addition, in order to further prevent the vehicle from moving, a mounting opening 12 is provided on the top of the main bridge plate 5, and a flip baffle 13 is rotatably connected in the mounting opening 12. When the flip baffle 13 is in a horizontal state, it is received in the mounting opening 12, and its upper end is flush with the main bridge plate 5, so as not to affect the movement of the vehicle along the main bridge plate 5.
[0032] In addition, two flip baffles 13 are provided, which are used to stand upright between the front and rear tires of the car to further fix the tires. In this embodiment, six connecting rods 8 are connected to one side of the movable support plate 10. Auxiliary connecting rods 15 are rotatably connected to two of the connecting rods 8, and the other ends of the auxiliary connecting rods 15 extend out of the top of the mounting hole 7 and are rotatably connected to one side of the flip baffle 13. Corresponding holes for accommodating the auxiliary connecting rods 15 are opened on the main bridge plate 5.
[0033] During the above process, the connecting rod 8 moves and partially extends out of the mounting hole 7. When the connecting rod 8 moves, the auxiliary connecting rod 15 pushes the flip baffle 13 to rotate. The flip baffle 13 changes from a horizontal state to a vertical state. The two flip baffles 13 are located between the two tires of the car. Therefore, whether the car moves forward or backward, it will be blocked by the flip baffle 13, which further fixes the car and prevents the car from slipping during maintenance, or even a bigger accident.
[0034] In addition, a support plate 16 is fixedly connected to the bottom of the column 1, and the support plate 16 is convenient for fixing the column 1 as a whole on the ground. At the same time, a groove 17 is opened on the support plate 16 and directly below the movable support plate 10. Because the main bridge plate 5 moves downward during resetting, the "V"-shaped movable support plate 10 will first contact the support plate 16. The connecting shaft 11 and a part of the two movable support plates 10 enter the groove 17. The edges of the groove 17 are chamfered. As the crossbeam 3 drives the main bridge plate 5 to move downward and reset, the two "V"-shaped movable support plates 10 are also reset to a horizontal state, and the connecting rod 8 is also stored back in the mounting hole 7. At the same time, the connecting rod 8 drives the flip baffle 13 to rotate in the opposite direction and reset through the auxiliary connecting rod 15. At this time, it is convenient to drive the car away from the main bridge plate 5.
[0035] The implementation process and principle of a vehicle maintenance fixing device in the embodiment of the present application are as follows:
[0036] The vehicle to be inspected is driven onto the main bridge plate 5 so that the wheels are located above the movable support plate 10. The motor 4 is started to drive the main bridge plate 5 to rise upward. As the main bridge plate 5 gradually contacts the bottom of the vehicle and drives the vehicle to rise upward, the two movable support plates 10 also change from a horizontal state to an inclined "V" shape, the connecting rod 8 is partially pulled out of the mounting hole 7, and the spring 9 is compressed.
[0037] At this time, the main bridge plate 5 directly lifts the car, and the tire part of the car is "trapped" in the positioning port 6 because the movable support plate 10 becomes an inclined "V" shape. It cannot move further. The middle part of the main bridge plate 5 is a hollow area, which is convenient for employees to perform maintenance.
[0038] In addition, during the movement of the connecting rod 8, the auxiliary connecting rod 15 can drive the flip baffle 13 to rotate to a vertical state. The two flip baffles 13 are located between the two tires of the car. Therefore, whether the car moves forward or backward, it will be blocked by the flip baffle 13, further fixing the car to prevent the car from slipping during maintenance and causing accidents.
[0039] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
