Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a non-return cover attached to an end of a drainage pipe of a sewer system, and relates to a non-return cover for preventing a bad odor, a mouse, or the like from entering a building through a drainage pipe.

[0002]

[Prior art]

 Conventionally, drainage pipes have been used to drain water from buildings, houses, etc. to the sewer pipe. This drain pipe normally uses a pipe with an open end, and the open end is continuous with the inside of the sewage mast or the sewer pipe.

[0003]

[Problems to be solved by the device]

 For this reason, there was the inconvenience that bad odors, rats, and pests entered from the sewage masu and sewer pipes through this open end, and penetrated through the drainage pipes to the inside of buildings and houses. In particular, in urban buildings, invading mice bite electric wires such as computer wiring and cause malfunctions, and in homes and other homes, bad odors flow backwards.

On the other hand, as the drainage pipe, pipes having various diameters are used at the place of use. Therefore, it has been desired to provide a non-return cover that can be used for any pipe having a different diameter. Therefore, this invention was devised to solve the above-mentioned problems, and it aims at deodorizing drainage pipes, rats, and insects, and is also a non-return cover that can be used for various pipes with different diameters. The purpose is to provide.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the first means of the present invention is to obliquely cut the opening end of the pipe forming the drainage pipe P to form the opening P1 protruding from the lower end of the opening edge. The lid 1 for pivoting the opening P1 is swingably provided on the upper end of the portion P1.

Further, the second means is to provide a pipe-shaped elastic coupling body Q that is coupled to the opening end portion of the pipe forming the drainage pipe P, and cut the opening end portion of this coupling body Q at an angle to open it. An opening Q1 protruding from the lower end of the edge is formed, and a lid 1 for covering the opening Q1 is swingably provided at the upper end of the opening Q1 while being connected to the drain pipe P of the connector Q. The notch opening Q2 is formed by cutting out the lower end of the opening edge of Sugagawa, and the notch Q3 is provided around the side surface of the connecting body Q provided with the notch opening Q2, and the notch opening Q2 is bent to drain water. The provision of the insertion portion Q4 to be inserted into the pipe P is a means for solving the problem.

The lid 1 of the third means is such that the end portion of the lid 1 is pivotally supported by a fastening pin 3 on a support 2 provided above the opening edge of the connecting body Q. is there.

[0008]

[Action]

 That is, according to the first means of the present invention, the lid 1 swingably provided at the upper end of the opening of the drainage pipe P opens at the time of draining, and then the opening P1 is opened by the weight of the lid 1 itself. It

The second means is to insert the insertion portion Q4 of the connection body Q into the drain pipe P so that the drain pipe P and the connection body Q are connected to each other, and the opening of the pipe-shaped connection body Q is opened. The part Q1 is so constructed that the lid 1 can be opened and closed.

Further, according to the third aspect, the lid body 1 is swingably coupled to the support body 2 provided at the upper end of the coupling body Q by the fastening pin 3.

[0011]

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

The non-return cover according to the present invention obliquely cuts the opening end of the pipe forming the drainage pipe P to form an opening P1 protruding from the lower end of the opening edge, and further providing this opening P1. The lid 1 is provided to open. The lid 1 shown in FIG. 1 is swingably provided at the upper end of the opening P1. At this time, the lid body 1 swingably connects the upper end portion of the lid body 1 to the support body 2 provided at the upper end portion of the drain pipe P.

The lid body 1 shown in FIG. 2 is provided in a coupling body Q that is coupled to the drain pipe P. That is, the connecting body Q is connected to the opening end of the pipe forming the drainage pipe P, and the opening end of the pipe-shaped elastic material is cut obliquely, and the lower end of the opening edge projects. Form Q1. A support 2 is provided at the upper end of the opening Q1, and the end of the lid 1 is pivotally supported by a fastening pin 3 so as to be swingable.

On the other hand, the cutout opening Q2 is formed by cutting out the lower end of the opening edge of the connecting piece Q connected to the drainage pipe P (see FIG. 4). Then, a notch Q3 is provided around the side surface of the connector Q provided with the notch opening Q2 (see FIG. 2). Further, the notch opening Q2 is bent from the notch Q3 and inserted into the drainage pipe P, and this inserted portion is used as an insertion portion Q4 (see FIG. 3). The insertion portion Q4 is for adjusting the diameter of the insertion portion Q4 arbitrarily by bending the side surface of the connection body Q with the cutout opening portion Q2, and the insertion portion Q4 inserted into the drain pipe P is used. Expands by its own elastic force and is crimped to the inner surface of the drain pipe P (see FIG. 4).

[0015]

[Effect of device]

 The present invention achieves the original purpose by being configured as described above. That is, according to the first and second aspects, since the opening of the drainage pipe can be covered with the lid 1, it is possible to prevent a bad odor, a mouse, or an invasion of harmful insects. Therefore, it is possible to prevent wiring accidents in the building due to mice and to prevent deodorization from drainage pipes of ordinary households.

Further, according to claim 1, it becomes possible to construct the drainage pipe P provided with the lid body 1 (see FIG. 5).

Further, according to claim 2, it can be used for various pipes having different diameters, and the mounting work can be performed very easily (see FIG. 6).

As described above, according to the present invention, various effects that are practically useful, such as deodorization, rodent prevention, and insect control of drainage pipes, and connection to various pipes with different diameters, can be achieved. It plays.
