Description

Technical Field

[0001] This utility model relates to the field of repair pad technology, and in particular to an automotive repair pad. Background Technology

[0002] During the use of a car, there will be times when the car needs to be repaired. If the problem is under the car, a repair mat is often used, where the driver and other personnel lie on the repair mat to carry out the repairs.

[0003] In the prior art, such as Chinese Patent No. CN205572397U, a multi-functional car repair mat is disclosed. Through the setting of a second serpentine tube and a funnel, the engine oil can be discharged from the funnel into the reservoir, thereby preventing the engine oil from being spilled or splashed when using a separate tool to collect the engine oil. The set of lights can provide illumination when the light under the car is poor.

[0004] In the above technical solution, when using a repair pad to crawl under the car for repairs, the bottom of the car has been driving on the road for a long time, and a lot of dust has accumulated on the chassis. During the inspection process, the dust will be shaken off. Since there is no protective mechanism on the top of the repair pad, the dust may enter people's eyes and affect the repair effect.

[0005] Based on this, a car repair mat is proposed. Utility Model Content

[0006] The purpose of this invention is to provide an automotive repair mat to solve the problems mentioned in the background art.

[0007] The technical solution of this utility model is as follows: a car repair mat, including a mat body, a support frame and a vertical plate are fixedly connected to the upper surface of the mat body respectively, an acrylic transparent cover is slidably disposed on the inner wall of the support frame, a scraper is fixedly connected to the inner wall of the support frame, the scraper is in contact with the surface of the acrylic transparent cover, a coil spring shaft is disposed on one side of the acrylic transparent cover, a rotating rod is fixedly connected to one end of the coil spring shaft, a wing-shaped locking block is fixedly connected to one end of the rotating rod, a through hole is opened through one side of the vertical plate, a fixing cylinder is fixedly connected to the inner wall of the through hole, the wing-shaped locking block is detachably connected to the inner wall of the fixing cylinder through a rotating disassembly device, and two return springs are fixedly connected to one side of the acrylic transparent cover, one end of each of the two return springs is fixedly connected to one side of the vertical plate respectively.

[0008] In some embodiments, the rotating disassembly device includes two rectangular grooves formed on the inner wall of the fixed cylinder. Trapezoidal blocks are slidably connected to the inner walls of the two rectangular grooves. A spring rod is fixedly connected to one side of each of the two trapezoidal blocks. A fixing plate is fixedly connected to the inner walls of the two rectangular grooves. A sliding hole is formed through one side of each of the two fixing plates. The inner walls of the two sliding holes are slidably connected to the surfaces of the corresponding two spring rods.

[0009] In some embodiments, a through hole is provided on one side of the fixed cylinder, a knob is rotatably connected to one side of the fixed cylinder, a prism is fixedly connected to one side of the knob, the inner wall of the through hole is adapted to be rotatably connected to the smooth surface on the prism, and a cavity is provided at one end of the rotating rod, the inner wall of the cavity is adapted to be slidably and detachably connected to the surface of the prism.

[0010] In some embodiments, a plurality of damping support cylinders are fixedly installed on the upper surface of the pad, and a plurality of pulleys are fixedly installed on the lower surface of the pad.

[0011] In some embodiments, an oil collection device and a lighting device are respectively provided on the pad.

[0012] Compared with existing technologies, the significant advantages of this invention are:

[0013] Firstly, this utility model uses a rotating knob, which, through the cooperation of a prism and a cavity, drives the rotating rod to rotate, which in turn drives the wing-shaped locking block to rotate. After rotating 90 degrees, the notch on the wing-shaped locking block corresponds to the trapezoidal block inside the fixed cylinder, thus releasing the restriction on the rotating rod. When reset by the return spring, the acrylic transparent cover will slide inside the support frame to protect the personnel's head. This can prevent mud and sand from the vehicle chassis from falling into the face and eyes during maintenance, thus affecting the maintenance work.

[0014] Secondly, after maintenance, the acrylic transparent cover can be pushed and the rotating rod can be reset under the action of the coil spring shaft, so that it can be locked into the fixed cylinder again to limit the acrylic transparent cover. In addition, during the process of the acrylic transparent cover sliding back and forth on the inner wall of the support frame, the scraper can scrape the dust on the surface of the acrylic transparent cover, improving the clear observation of maintenance personnel.

[0015] This solves the problem that during the existing maintenance process, dust would be shaken off due to vibration, and since there was no protective mechanism above the maintenance pad, dust might get into people's eyes, affecting the maintenance effect. Attached Figure Description
