Detailed Description

In order to fully understand the objects, features and effects of the present invention, the conception, specific structure and technical effects of the present invention will be further described with reference to the accompanying drawings.

The sewer pipe in the prior art is generally connected with a thread sleeve through soldering tin at the position of a pipe opening so as to be convenient for the connection between adjacent sewer pipes and realize water supply and drainage work. However, soldering the threaded socket at the nozzle can generate solder waste, which can cause discomfort to the worker over time. In addition, the thread tooth socket connected by soldering tin may be unstable and easy to peel off due to insufficient soldering tin, poor quality of the solder material and other problems, and the like, and the connection between the thread tooth socket and the pipe body is poor in stability.

In order to solve the above problem, as shown in fig. 1 and 2, the present invention provides a sewer pipe, which includes: the pipe body 100 is provided with a flange 111 and a flange 112 at a pipe orifice 110, wherein the flange 112 is arranged below the flange 111; a thread insert 200 having an upper surface 210 and a lower surface 220, wherein when the lower surface 220 abuts against the flange 112, the upper surface 210 abuts against the flange 111, so that the thread insert 200 is tightly fitted to the pipe 100.

Adopt the sewer pipe of above-mentioned structure, because the flange 112 of its body offsets with the lower surface 220 of screw thread facing, the upper surface 210 of screw thread facing offsets with the turn-ups 111 of body to in the vertical direction, press from both sides tightly and spacing about going on screw thread facing 200 through turn-ups 111 and flange 112, make screw thread facing 200 unable gliding and unable toward the mouth of pipe orientation pine take off, simultaneously, the size of screw thread facing 200 with the size phase-match of body, thereby realize screw thread facing 200 and body 100 and closely cooperate. The utility model discloses compare with the sewer pipe among the prior art, it is fixed screw thread facing 200 through above-mentioned structure, has not only avoided soldering tin insufficient and the unstable structure that leads to, does not produce soldering tin waste gas in the production process moreover, avoids causing injury and polluted environment to workman's health, and its turn-ups and flange can be accomplished with the help of the mechanical equipment punching press in addition, need not staff soldering tin, have improved production efficiency.

Wherein, the utility model discloses a screw thread facing and body can adopt same kind of material to make, make things convenient for waste recovery, and prior art's sewer line because it adopts soldering tin to connect, still probably need separate soldering tin when retrieving waste, the waste recovery of being not convenient for.

As a preferable embodiment of the present invention, the protruding direction of the flange 112 is perpendicular to the central axis direction of the pipe orifice 110. The projection direction of the sewer pipeline adopting the structure is vertical to the direction of the central axis, so that the upper part and the lower part of the flange are stressed evenly when the flange is formed, the rigidity of the pipe body is ensured, and the thread tooth socket can be tightly matched with the pipe body.

As a preferable embodiment of the present invention, the flange 112 is circular. By adopting the sewer pipeline with the structure, the lower surface of the thread sleeve 200 can be supported in a surrounding manner, and the structural stability of the sewer pipeline is improved.

Further, the body includes: a water inlet end 120, a water outlet end 130, and a connecting tube 140 for connecting the water inlet end 120 and the water outlet end 130; the flange 112 is disposed on the water inlet end 120 and/or the water outlet end 130. The flange can be arranged at the water inlet end, the water outlet end or both the water inlet end and the water outlet end according to actual use requirements, so that the flange can be changed according to different use conditions.

Further, the water inlet end and/or the water outlet end are/is provided with a thread tooth socket according to the requirement or not for flaring treatment to form a flaring part, and the diameter of the water inlet end and the diameter of the water outlet end are increased so as to pre-fix the thread tooth socket in the horizontal direction.

As shown in fig. 3 and 4, the pipe body is a U-shaped pipe bent in a U-shape, a right-angled bent pipe bent in a right-angled shape, or a straight pipe.

As the utility model discloses an above-mentioned sewer line's an preferred scheme: the pipe body is made of metal materials or PVC materials.

The present invention is not limited to the above embodiment, and if various modifications or variations of the present invention do not depart from the spirit and scope of the present invention, they are intended to be covered if they fall within the scope of the claims and the equivalent technology of the present invention.
