Description

Quick joint structure of pipe joint

The present invention relates to a quick-connect structure for a pipe joint, which provides a quick-connect structure for a pipe joint that can be quickly assembled or disassembled between a pipe member and a pipe joint.

According to the current assembly of pipe fittings, most of them are connected and assembled by various types of pipe joints. The general pipe joints include: pipe joints, bent joints, two-way joints, multi-way joints (such as three-way joints, four-way joints). Etc.) For the convenience and speed of construction, there are various types of quick joints, such as the Republic of China No. M551672 "Improvement of Pipe Joint Structure" and the No. M423771 "Pipe Quick Joint" patent, which is characterized by the nozzle of the pipe joint. The inside is provided with an O-ring (O-ring), a sealing ring (cone), a restraining member (a snap ring), a control group (a locking cap, a disassembly ring), and a positioning ring (a locking cap stop member). ), the O-ring (O-ring) is used for sealing the pipe (pipe) after insertion into the pipe joint and the outer wall of the pipe, and the sealing ring (cone seat) is used to prevent the above-mentioned snap ring from being inserted into the pipe body (pipe) Directional movement, restraining member (snap ring) is used to clamp the pipe body (pipe), control group (locking cap, disassembly ring) is used for the release of the pipe body (pipe), positioning ring (locking cap stop member) ) to prevent internal components from exiting; due to the pipe body (pipe) The seal between the pipe joint and the pipe joint relies on the O-ring (O-ring) to seal and leak, so the stability of the O-ring (O-ring) is extremely important, and the O-ring (O-ring) After being installed inside the nozzle of the pipe joint, it is pressed by the sealing ring (cone seat), and the O-ring (O-ring) is attached to the positioning ring together with other components (locking cap stop) The component is fixed in the nozzle of the pipe joint, and the positioning ring (locking cap stop component) is placed in the nozzle of the pipe joint, and not all the components are completely locked. It only restricts (prevents) the internal parts of the pipe joint from being withdrawn, so the O-ring (O-ring) reduces the sealing force between the pipe (pipe) and the pipe joint.

In view of this, the creator is actively researching and developing a quick-connect structure with a simple structural joint and ensuring its sealing and leak-stop function.

The main purpose of the present invention is to provide a quick-connecting structure of a pipe joint, in particular to a quick-connecting structure which is arranged in the nozzle of each type of pipe joint and provides quick assembly or disassembly, which is mainly used for the pipe joint of the pipe joint. Inside, the O-ring seal, the lock washer, the pusher, the gland and the retaining ring are arranged from the inside to the outside; the inner side wall of the pipe joint is provided with a pipe abutment from the inside to the outside. a ring groove, a tapered taper portion, a ring stop portion and a retaining ring groove; the lock washer is a hollow thin ring piece, the inner edge of which has a plurality of teeth extending obliquely toward the center, and the push piece is a ring shape The front end ring is provided with a shoulder with an outer oblique guiding surface, and the inner part of the pressing cover is provided with an inner retaining edge; the ring groove in the pipe joint nozzle is for the O-ring sealing, and the locking gasket The pressing member, the gland and the retaining ring are then sequentially installed in the tube In the nozzle of the joint, the locking washer is abutted against the ring stop portion, and the gland is pressed against the rear side of the lock washer, and the shoulder of the pusher member with the outer oblique guide surface is subjected to the inner block. The edge is limited to the inside of the gland, and finally the retaining ring is embedded in the retaining ring groove, and the locking washer, the pressing member and the gland are locked in the nozzle of the pipe joint by the retaining ring; when the pipe fitting is made of the pipe joint The insertion of the mouth and the teeth of the locking gasket will bite the pipe. When the pipe is to be disassembled, the pressing member can be urged to push the front end of the locking piece to disengage the pipe. Bite, so that the pipe fittings can be quickly assembled and disassembled by the pipe joints.

The details and technical means of this creation are listed below with reference to the specific embodiments: Please refer to the first and second figures. This is a quick-connect structure for pipe joints, especially a quick-connect structure that is installed in the nozzles of various pipe joints to provide quick assembly or disassembly. The nozzle of the pipe joint 10 is provided with an O-ring 20, a lock washer 30, a pusher 40, a gland 50 and a retaining ring 60 from the inside to the outside; the pipe joint 10 is on the inner side wall of the pipe joint The tube abutting portion 11, the ring groove 12, the inclined taper portion 13, the ring stop portion 14 and the retaining ring groove 15 are sequentially arranged from the inside to the outside; the locking washer 30 is a hollow thin ring piece whose inner edge faces a plurality of teeth 31 extending obliquely in the center, and the pressing member 40 is in the shape of a ring, and the front end ring is provided with a shoulder 41 having an outer inclined guiding surface, and the inside of the pressing cover 50 is provided with an inner retaining edge 51; The ring groove 12 in the nozzle of the pipe joint 10 is for the O-ring 20 to be embedded, and the lock washer 30, the pressing member 40, the gland 50 and the retaining ring 60 are sequentially installed on the pipe joint 10 In the nozzle, the locking washer 30 is abutted against the ring stop portion 14, and the gland 50 is pressed against the rear side of the locking pad 30, and the front end of the pressing member 40 has an outer oblique guiding shoulder. 41 is limited by the inner retaining edge 51 to the inside of the gland 50, and finally The retaining ring 60 is then inserted into the retaining ring groove 15, and the locking washer 30, the pressing member 40 and the gland 50 are locked in the nozzle of the pipe joint 10 by the retaining ring 60.

When implemented, when the tubular member 70 is inserted through the nozzle of the pipe joint 10, the front end of the tubular member 70 is pressed against the pipe abutting portion 11, and the tubular member 70 pushes the respective teeth 31 on the locking gasket 30, and the locking member is tightened. Each of the teeth 31 of the gasket 30 bites the pipe member 70 (as shown in the third figure), and the O-ring 20 embedded in the pipe joint 10 has a good seal between the pipe member 70 and the pipe joint 10. Leakage effect.

When the pipe fitting 70 is to be disassembled, the sleeve 80 can be removed by the sleeve. Before the head 10 nozzle (as shown in the fourth and fifth figures), the force is applied to disassemble the collar 80 against the rear end of the pressing member 40, and the pushing member 40 is pushed to push the locking washer 30 to the front end. The upper teeth 31 are such that the teeth 31 on the locking washer 30 are disengaged from the tubular member 70, and the tubular member 70 can be withdrawn from the pipe joint 10.

The general pipe joints include: pipe cover joints, bent joints, two-way joints, multi-way joints (such as three-way joints, four-way joints, etc.), and the quick joint structure of the joints can be applied to the aforementioned For the pipe joint of the model, please refer to the sixth to eighth figures, which is a schematic diagram of the implementation of the two-way joint 10', the cap joint 10", and the three-way joint 10"'.
