Description

Technical Field

[0001] The utility model relates to the technical field of rodent-proof devices, in particular to a rodent-proof device for sewers. Background Art

[0002] A sewer is a type of urban public facility, referring to pipes that discharge sewage and rainwater from buildings; it also refers to underground passages that drain sewage and rainwater from cities, factories or villages. In order to prevent rats from crawling from sewers into residential buildings, sewer rat prevention devices are needed.

[0003] According to the description of a sewer rat-proofing mechanism disclosed in the patent website (authorization announcement number: CN 218264264U), "The utility model provides a sewer rat-proofing mechanism, including a waterway body, an annular plate is installed inside the waterway body, and a plurality of pointed heads are evenly installed on the inner side wall of the annular plate. Both sides of the annular plate are elastic and slidably matched with a plurality of sliding rods, and a plurality of first arc plates and inclined blocks are respectively installed at both ends of the sliding rod; a plurality of rubber protrusions are evenly installed on the outer side wall of the first arc plate, and one end of the rubber protrusion is matched with the inner side wall of the waterway body, and two second arc plates are slidably matched on both sides of the annular plate. The utility model provides a first arc plate, and the sliding rod drives the first arc plate under the drive of the inclined block, and the first arc plate drives the rubber protrusion to position the annular plate, thereby reducing the situation where rats in the sewer pass through the pointed heads to enter the home, reducing the situation where rats cause trouble in the home, and making the process of family rat-proofing more convenient."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use of the utility model, due to the first curved plate provided, the sliding rod drives the first curved plate under the drive of the inclined surface block, and the first curved plate drives the rubber protrusion to position the annular plate, thereby reducing the situation where mice in the sewer pass through the pointed tip and enter the home. However, during actual use, when the user moves the sliding column, it is easy for the user's hand to come into contact with the pointed tip, thus causing certain safety hazards. Moreover, when the annular plate needs to be disassembled, it is inconvenient for the user to take the annular plate, and the user is easily stabbed by the pointed tip. Therefore, it has certain limitations, and therefore it is necessary to improve a sewer rodent-proofing device to solve the above problems. Utility Model Content
