Abstract

A non-skid interface for a cast pipe pertains to a non-skid interface structure of a pipe joined up by T-shaped cast pipes. A labiated rubber gasket used for sealing is inlaid and arranged inside an inner groove of a pipe socket of the cast pipe. A faucet of the other cast pipe is inserted into the pipe socket of the cast pipe and presses the labiated rubber gasket firmly between the pipe socket of the cast pipe and the faucet. Non-skid steel nails are inlaid and arranged evenly inside the rubber gasket. The utility model is simple in structure, economical and practical, convenient and handy to arrange, high in efficiency and good non-skid effect.

Description

The anti-slip interface of cast tube

(1), technical field

The utility model belongs to a kind of anti-slip interface structure that connects into pipeline with T type cast tube.

(2), background technique

At present, when T type cast tube connects into pipeline, in the bellmouth inner groovy of cast tube, put into the rubber ring that is used for sealing, the socket of another root cast tube inserts in the bellmouth of described cast tube, rubber ring tightly is squeezed between the bellmouth and socket of cast tube, realizes sealing and anti-slip with this.But because the rubber ring intensity that full rubber is done is low, non-deformability is poor, and anti-slip effect is unsatisfactory.

(3), summary of the invention:

In order to overcome the shortcoming of prior art, the utility model provides a kind of T type cast tube anti-slip interface, and it is not only simple in structure, the economic use, and convenient and quick construction, and the efficient height, anti-slip effective.

The technical scheme in the invention for solving the technical problem is: be embedded with the rubber ring that is used for sealing in the inner groovy of cast tube bellmouth, the socket of another root cast tube is inserted in the bellmouth of described cast tube, rubber ring tightly is squeezed between the bellmouth and socket of cast tube, evenly is embedded with anti-skidding steel nail in the described rubber ring.

Since be the even anti-skidding steel nail of setting-in in rubber ring, thus simple in structure, the economic use, installation is convenient and swift, and the efficient height is anti-slip effective.By the anti-pull-off ability of DN100 T type rubber ring is measured, doubly than common high 8-9.

(4), description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the utility model partial sectional view;

Fig. 2 is the utility model rubber ring sectional view.

(5), embodiment

Be embedded with the rubber ring 3 that is used for sealing in the inner groovy 4 of cast tube bellmouth 5, the socket 1 of another root cast tube is inserted in the bellmouth 5 of described cast tube, rubber ring 3 tightly is squeezed between the bellmouth 5 and socket 1 of cast tube, as shown in Figure 1.The even anti-skidding steel nail 2 of setting-in in the described rubber ring 3, as shown in Figure 2, anti-skidding steel nail 2 one ends lean against on the anticreep wall 7 of cast tube bellmouth 5 inner groovies 4, and the other end is near the external cylindrical surface of cast tube socket 1.In order to improve anti-slip ability, anti-skidding steel nail 2 contacts with the external cylindrical surface of socket 1 overhead kick 6 on the wall.

Claims

1, the anti-slip interface of a kind of cast tube, in the inner groovy (4) of cast tube bellmouth (5), be embedded with the rubber ring (3) that is used for sealing, the socket of another root cast tube (1) is inserted in the bellmouth (5) of described cast tube, rubber ring (3) tightly is squeezed between the bellmouth (5) and socket (1) of cast tube, it is characterized in that: evenly be embedded with anti-skidding steel nail (2) in the described rubber ring (5).

2, anti-slip interface according to claim 1 is characterized in that: anti-skidding steel nail (2) one ends lean against on the anticreep wall (7) of cast tube bellmouth (5) inner groovy (4), and the other end is near the external cylindrical surface of cast tube socket (1).

3, anti-slip interface according to claim 1 and 2 is characterized in that: described anti-skidding steel nail (2) contacts with the external cylindrical surface of socket (1) overhead kick (6) on the wall.
