[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for the installation and fixing device of a drainage ditch cover, including a ditch body 1, a cover body 3 installed on the upper end of the ditch body 1, a limit hole 2 opened at the upper end of the ditch body 1, a hinge 5 installed between the ditch body 1 and the cover body 3, a storage groove 4 opened on the ditch body 1, a locking mechanism 6 provided in the cover body 3, and a warning mechanism 7 installed in the storage groove 4. The locking mechanism 6 can realize the quick opening and closing of the cover body 3, which is convenient for users to clean the drainage ditch, and the warning mechanism 7 can serve as a warning to pedestrians during construction.

[0024] like Figure 2 and Figure 3As shown, a hinge 5 is installed between the ditch body 1 and the cover body 3. The ditch body 1 has a storage groove 4. The locking mechanism 6 includes an installation groove 605 in the cover body 3. A first spring 603 is installed in the installation groove 605. A spring seat 602 is movably installed in the installation groove 605. A locking tongue 601 is fixedly installed on the spring seat 602. The locking mechanism 6 also includes a wire groove 604 in the cover body 3. A wire rope 606 is movably installed in the wire groove 604. One end of the wire rope 606 is fixedly installed on the spring seat 602. A handle 607 is fixedly installed on the other end of the wire rope 606. A groove is opened on the surface of the cover body 3. The handle 607 is connected to the cover body 3 through the groove. The cover body 3 is rotatably installed on the ditch body 1 by the hinge 5. The cover body 3 is restricted to the ditch body 1 by the locking tongue 601.

[0025] Specifically, after the cover body 3 is placed over the drain body 1, the first spring 603 applies force, pushing the spring seat 602 forward, which in turn causes the locking tongue 601 to engage in the limiting hole 2. This action ensures that the cover body 3 is firmly fixed above the drain body 1. At the same time, the user can pull up the handle 607. Once the handle 607 is pulled up, the wire rope 606 will correspondingly pull the locking tongue 601, disengaging it from the limiting hole 2, thereby releasing one side of the cover body 3. Subsequently, the user can continue to pull up the handle 607, causing the cover body 3 to rotate and unfold around the hinge 5, making cleaning and maintenance of the drain simple and quick.

[0026] like Figure 4 and Figure 5 As shown, the warning mechanism 7 includes a mounting shaft 707 rotatably mounted in the storage slot 4, a rotating seat 706 fixedly mounted on the mounting shaft 707, a crossbar 701 rotatably mounted on the rotating seat 706, a warning banner 702 fixedly mounted on the crossbar 701, a positioning seat 703 fixedly mounted inside the crossbar 701, a limit rod 708 slidably mounted inside the crossbar 701, a second spring 704 installed inside the crossbar 701, and a mounting hole provided on the storage slot 4, through which the mounting shaft 707 is rotatably mounted in the storage slot 4.

[0027] Specifically, the crossbar 701 can be rotated out of the storage slot 4 and positioned appropriately. During this process, the warning banner 702 wrapped around the crossbar 701 can be rotated and unfolded, thus achieving a warning effect. Once the warning banner 702 is fully released, the operator can easily loosen the sliding seat 705. The loosening of the sliding seat 705 allows the second spring 704 to function, which automatically pushes the limiting rod 708 forward. The front end of the limiting rod 708 abuts against the inner wall of the storage slot 4, effectively limiting further rotation of the crossbar 701. In this way, the crossbar 701 and the warning banner 702 are fixed to one side of the cover body 3, ensuring that the warning banner 702 can be stably displayed, thereby serving to warn pedestrians. Furthermore, after use, the entire crossbar 701, along with the warning banner 702, can be conveniently retracted into the storage slot 4, saving space and facilitating future use.

[0028] Working principle: After the cover plate body 3 is covered, the first spring 603 will push the spring seat 602 to move forward, so that the locking tongue 601 is inserted into the limiting hole 2, thereby fixing the cover plate body 3 above the drainage ditch body 1. At the same time, the user can pull up the handle 607. After pulling up the handle 607, the wire rope 606 will pull the locking tongue 601 out of the limiting hole 2, releasing one side of the cover plate body 3. Then, the user can continue to pull up the handle 607, so that the cover plate body 3 can rotate and unfold around the hinge 5, making it convenient for the user to clean the drainage ditch. After the cover body 3 is opened, the crossbar 701 can be rotated out of the storage slot 4. After the crossbar 701 is rotated out of the storage slot 4, it can be rotated to release the warning banner 702 wrapped around it. After the warning banner 702 is released, the sliding seat 705 can be loosened. After the sliding seat 705 is loosened, the second spring 704 will push the limiting rod 708 forward, so that the end of the limiting rod 708 abuts against the storage slot 4, restricting the rotation of the crossbar 701 and fixing the banner to one side of the cover body 3, thus serving the purpose of warning pedestrians. After use, the crossbar 701 and the warning banner 702 can be stored back into the storage slot 4.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
