Technical Field

[0001] The utility model relates to the technical field of vehicle body flip electrophoresis auxiliary equipment, and specifically discloses a tool box cover fixing device for vehicle body flip electrophoresis. Background Art

[0002] Electrophoresis is a coating process that uses electrochemical principles. To ensure that the coating of the vehicle body is uniform and smooth, the vehicle body needs to be coated with electrophoretic paint on the surface of the vehicle body before painting, thereby improving the anti-corrosion ability of the vehicle body, effectively blocking moisture and harmful substances, slowing down the erosion, and thus extending the service life of the vehicle body. Currently, the most common electrophoresis processes are the cage swing-rod electrophoresis process and the flip electrophoresis process. Since the flip electrophoresis process can better discharge the gas in the inner cavity of the vehicle body, so that the vehicle body can obtain a better electrophoresis effect, the application ratio of the flip electrophoresis process is gradually increasing.

[0003] When the vehicle body is undergoing the flip electrophoresis process, the vehicle body needs to be placed in the electrophoresis tank; usually, a tool box cover is installed on the truck body. To ensure that the tool box cover does not bump into the electrophoresis tank body when the vehicle body is flipped, and to avoid damage to the equipment and the vehicle body, the operator needs to use special tooling to fix and lock the vehicle body and the tool box cover. After the vehicle body completes the flip electrophoresis process, the above-mentioned prior art needs to forcibly dismantle the special tooling because the tool box cover and the vehicle body are in a fastened and locked state. On the one hand, it will consume a lot of operating time and affect production efficiency. On the other hand, the forced dismantling of the special tooling will damage the vehicle body, making it difficult to ensure production quality. Utility Model Content

A round rod 5 is provided inside the cylindrical portion 4. The top end of the round rod 5 can pass through the cylindrical portion 4 and be engaged with the inner end surface of the base 1, and the bottom end of the round rod 5 can extend out of the cylindrical portion 4. An L-shaped opening 10 is provided on the outer wall of the cylindrical portion 4. The round rod 5 is connected with a lever 7, and the lever 7 is a Z-shaped structure. The bottom and top rod bodies of the lever 7 are arranged in parallel; a connecting portion 14 is provided at the end of the top rod body of the lever 7, and a threaded hole 13 is provided at the top end of the round rod 5. The threaded hole 13 is arranged on the inner side of the cylindrical portion 4 and located in the L-shaped opening 10, and the connecting portion 14 is connected to the threaded hole 13.

[0028] A connecting block 6 is fixedly installed at one end of the bottom of the round rod 5, and the connecting block 6 is in contact with the inner plate of the tool box cover; the connecting block 6 is a square structure, and a first chamfered surface 15 is provided on the inner end surface of the connecting block 6, and two first chamfered surfaces 15 are provided and arranged opposite to each other; a second chamfered surface 16 is provided on the outer end surface of the connecting block 6, and four second chamfered surfaces 16 are provided.

[0029] Among them, a gasket 11 is provided on the inner side of the connecting block 6 and is sleeved on the outer periphery of the round rod 5. The gasket 11 is arranged at the bottom end of the round rod 5. A through circular hole is provided in the center of the gasket 11, and the circular hole can facilitate the passage of the round rod 5; a spring 12 sleeved on the outer periphery of the round rod 5 is installed between the gasket 11 and the cylindrical portion 4; the spring 12 is sleeved on the round rod 5, and its length is slightly greater than the length of the round rod 5, so that the spring 12 is always in a compressed state during use.
