[0010] The utility model adopts the above structure to achieve the following beneficial effects:

[0011] The utility model can realize the rapid installation of the water receiving trough in the gap between the bridges by arranging the installation mechanism, and can make up for the expansion and contraction between the bridges by cooperating with the expansion and contraction of the expansion plate, and the supporting plate can also serve as the upper cover plate. The design is ingenious, and the water receiving trough is easy to replace and disassemble, which is convenient for the later maintenance work. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0019] like Figure 1-4The utility model discloses a bridge expansion joint structure, comprising a bridge plate 1, a fixing plate 2 is arranged on the side wall of the bridge plate 1, a space is provided between the fixing plates 2, the upper end surface of the fixing plates 2 is lower than the top surface of the bridge, so as to facilitate the placement of a cover plate on the fixing plates 2, a water receiving trough 3 is arranged in the gap between the bridge plates 1, the water receiving trough 3 is made of rubber material, a connecting plate 4 is arranged at the upper end of the water receiving trough 3, a mounting mechanism 5 is arranged at the upper end of the connecting plate 4, and the mounting mechanism 5 can be installed in the fixing plate 2;

[0020] like Figure 1-3 The mounting mechanism 5 includes a supporting plate 7, a hollow groove 8 is provided in the supporting plate 7, a telescopic plate 6 is slidably provided in the hollow groove 8, a spring 9 is provided at the end of the telescopic plate, and the other end of the spring 9 is fixedly connected to the inner wall of the hollow groove 8. When the telescopic plate 6 is installed in the placement groove 11, the spring 9 will have elastic force on the telescopic plate 6. A mounting hole 10 is provided in the telescopic plate 6. The telescopic plate 6 is fixedly connected to the connecting plate 4. By buckling the telescopic plate 6 to the fixed plate 2 and passing the bolt through the mounting hole 10, the telescopic plate 6 can be fixed to the fixed plate 2. The bridge can be extended and retracted, and the telescopic plate 6 can be pushed to slide in the supporting plate 7 to compensate for the extension and retraction of the bridge. The top of the supporting plate 7 can also support the cap covering the gap between the bridges. The installation is convenient, and it is also convenient to disassemble and replace the water tank 3.

[0021] like Figure 4 A plurality of placement grooves 11 are provided in the fixed plate 2, and the telescopic plate 6 can be placed in the placement grooves 11. When the telescopic plate 6 is placed and installed in the placement grooves 11, the upper end surface of the supporting plate 7 must be lower than the top surface of the bridge.

[0022] During specific use, when installing the expansion joint water trough 3 between the bridges, first align the telescopic plate 6 with the corresponding placement groove 11 and put it in. The telescopic plates 6 on both sides will be stuck into the placement groove 11 at the same time, and the telescopic plates 6 can be fixed on the fixed plate 2 by passing bolts through the installation holes 10, and the upper end of the fixed plate 2 can then be covered with some cover plates.

[0023] When debris or rainwater falls into the expansion joint of the bridge, it will be received by the water collecting trough 3. When the bridge is expanded or contracted, it will push the fixed plate 2 and the connecting plate 4. The connecting plate 4 will push the expansion plate 6 to slide in the supporting plate 7 to compensate for the expansion and contraction of the bridge. The spring 9 will always press the expansion plate 6. When disassembly is required, only the bolts in the mounting holes 10 need to be loosened, and the connecting plate 4 and the water collecting trough 3 can be taken out from the gap between the bridges for replacement, which is very convenient.
