Problems solved by technology

Since the screw rotates close to the seal, the rotational friction is large, and when the nut is turned, the screw will follow the rotation. Therefore, special tooling and fixtures are required. At the same time, because the extrusion of the seal requires a large force, the structure of the scheme is complex and difficult to operate. strenuous and costly

Embodiment Construction

[0033] The technical solutions of the present invention will be further illustrated and described below through specific embodiments in conjunction with the accompanying drawings.

[0034] The sealing connection mechanism of the present invention is used to seal and fix the pipe fittings on the wall hole. Different from the material of pipe fittings, it is not easy to form a more precise connection structure in the wall hole, such as the ceramic opening in the toilet tank for fixing the water inlet valve or the drain valve, or the partition wall of the toilet jet water pipeline or the brush ring water pipeline Ceramic openings, etc., but not limited thereto. Therefore, through the sealed connection mechanism of the present invention, fluid can be introduced or drawn into another pipeline through the pipe fitting.

[0035] like Figure 1-5 As shown, the sealing connection mechanism is used to seal and fix the pipe fitting 300 on the solid object or the wall hole 410 of the pi...

Abstract

The invention discloses a sealing connecting mechanism which is used for sealing and fixing a pipe fitting to a wall hole. The sealing connecting mechanism comprises an embedded part (100) inserted and embedded in a wall hole (410) when at a working position, a pipe fitting (300) with a radial outward flange (310) and an elastic sealing part (200) located between the pipe fitting flange (310) and a wall hole outer end face (411). The pipe fitting (300) and the embedded part (100) are provided with threaded sections (320 and 150) matching each other. When at the working position, the elastic sealing part (200) is squeezed between the flange (310) and the wall hole outer end face (411) through the threaded sections (320 and 150), and the two end faces of the elastic sealing part (200) abut against the flange (310) and the wall hole outer end face (411) respectively to form sealing. The sealing connecting mechanism is simple in structure, has fewer component and is low in cost, quick and convenient to install and good in sealing effect.

Description

technical field [0001] The invention relates to a sealing connection mechanism, which is used for sealing and fixing a pipe fitting on a wall hole. Background technique [0002] In some toilet flushing waterways, it is necessary to seal and fix the plastic pipe fittings in the ceramic hole of the toilet. At present, the copper screw, copper nut and seal are used to cooperate. The seal is placed between the copper screw and the copper nut, and the copper nut withstands the seal. During assembly, the copper screw is turned to pull back the copper screw to forcibly squeeze the seal to expand the seal radially, and then the copper screw presses the seal against the surface of the ceramic hole to achieve the sealing effect. Since the screw rotates close to the seal, the rotational friction is large, and when the nut is turned, the screw will follow the rotation. Therefore, special tooling and fixtures are required. At the same time, because the extrusion of the seal requires a l...
