[0003] After searching, the patent number is CN212611936U, and the name is a utility model of an expansion joint device with anti-sinking function, including a first comb plate and a second comb plate that cooperate with each other. Through research and analysis, it is found that although the device effectively prevents the wheel from sinking, the anti-sinking structure is simple, and when the comb plate moves, the comb plate can squeeze the elastic column in, thereby not affecting the normal contraction of the comb plate, but, to a certain extent, there are still the following disadvantages.
[0004] For example, the cross-setting method has a high production cost, a complicated processing process, average waterproof performance, and is inconvenient to clean. During the expansion and contraction process of the expansion joint, the comb plate is easily damaged and difficult to repair, and the anti-sinking performance is average. In order to solve the above technical problems, we have designed a precision impact-resistant expansion joint with anti-sinking function. Utility Model Content
