Description

a sealing cap

technical field

The utility model relates to a pipeline sealing device, in particular to a sealing cover.

Background technique

In the construction of modern cities, plugging caps are more and more used in the sealing of underground pipelines, and the quality of the plugging caps directly affects the sealing problem during installation. Existing plugging caps are generally provided with threaded holes in the center of one side of the entire cap body. In the process of installing relatively large plugging caps, it may happen that the screw rod installed on the threaded hole is too large because the cap body is too large. In the process of tightening the plugging cap, it is not easy to use force and the force is unstable, which leads to the failure of the sealing cap to be installed tightly.

Utility model content

The technical problem to be solved by the utility model is to provide a new type of plugging cap, which solves the problem that in the prior art, because the cap body is too large, the screw rod installed on the threaded hole is not easy to exert force and use in the process of tightening the plugging cap. The situation of unstable force leads to the problem that the sealing cover cannot be installed tightly.

The technical scheme of the utility model for solving the above-mentioned technical problems is as follows: a plugging cover, including a cover body and a sealing gasket, the sealing gasket is located at the edge of the lower side of the cover body, and the cover body is provided with threaded holes, The threaded hole is located at the center of one side of the cover body, and an annular positioning groove concentric with the threaded hole is provided around the threaded hole, and a rotating hole is provided beside the positioning groove; the rotating hole is provided with One or more and evenly distributed beside the positioning groove.

The beneficial effects of the utility model are: a positioning hole is provided around the threaded hole on the existing plugging cap, and a rotating hole is also provided on the cap body, so that the force is stable and the sealing is tight during the process of tightening the plugging cap. The lid seals well.

Description of drawings

Fig. 1 is the plane structure schematic diagram of a kind of plugging cover of the present utility model;

Fig. 2 is a side view of a blocking cap of the present invention.

In the accompanying drawings, the list of parts represented by each label is as follows:

1. Cover body, 2. Rotation hole, 3. Positioning groove, 4. Sealing gasket, 5. Threaded hole.

Detailed ways

The principles and features of the present utility model are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the utility model, and are not used to limit the scope of the utility model.

As shown in Figures 1 and 2, a plugging cover includes a cover body 1 and a sealing gasket 4, the sealing gasket 4 is located at the edge of the lower side of the cover body 1, and the cover body 1 is provided with threaded holes 5. The threaded hole 5 is located at the center of one side of the cover body 1, and an annular positioning groove 3 concentric with the threaded hole 5 is provided around the threaded hole 5, and a rotating hole is provided beside the positioning groove 3 2; There are three rotating holes 2 and they are evenly distributed beside the positioning groove 3 .

In the process of installing the plugging cover, when the screw is installed in the threaded hole 5, use the positioning hole 3 for positioning, so as to avoid the situation that the cover body 1 is not easy to use force and unstable during the process of installing the screw. The movement causes the sealing cap not to be tightly installed. Before the sealing installation, the cover body 1 is rotated by using the rotating hole 2 to make the cover body 1 reach the best sealing position, and the sealing gasket 4 strengthens the sealing performance of the blocking cap.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model shall be included in this utility model. within the scope of protection of utility models.

Claims (2)

1. A plugging cap, characterized in that: it comprises a cover body and a gasket, the gasket is located at the edge of the lower side of the lid body, the lid body is provided with a threaded hole, and the threaded hole is located at the edge of the lid body. At the center of one side of the body, an annular positioning groove concentric with the threaded hole is provided around the threaded hole, and a rotating hole is provided beside the positioning groove. the 2. A sealing cap according to claim 1, characterized in that: one or more than one rotating holes are evenly distributed beside the positioning groove. the
