Description

A locking type quick connector

technical field

The invention relates to the fields of agricultural irrigation and low water pressure environment, in particular to a locking type quick-plug joint.

Background technique

In the fields of agricultural irrigation and low water pressure environments, plastic pipes and quick-connect fittings are widely used, but the existing quick-plug fittings and plastic pipes are generally hard-connected. In complex environments, quick-plug fittings and plastic pipes are subject to vibration or displacement. During the process, due to the hard connection, there is no allowance for vibration or displacement, which easily leads to loosening and damage of the joint, and water seepage and leakage.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a locking type quick-plug joint, which solves the problems of easy loosening, damage, water seepage and water leakage of traditional hard connections.

In order to achieve the above-mentioned purpose, the technical solution provided by the present invention is to include an integrally formed spherical body and a water pipe connection end, the water pipe connection end is provided with a throat hoop locking groove, and a throat hoop is clamped in the throat hoop locking groove. The inner wall of the water pipe connection end is provided with a plurality of water pressure buffer sealing protrusions, two contact ends are formed on the water pressure buffer sealing protrusion, and the water pressure buffer sealing protrusion in the middle of the two contact ends is An arc-shaped opening is opened on the upper part, a water pipe is clamped in the connecting end of the water pipe, and the contact end is in contact with the outer wall of the water pipe.

Further, the distance between two adjacent water pressure buffer sealing protrusions is equal and is 0.3-0.6CM.

Further, there are no less than three water pressure buffer sealing protrusions.

The beneficial effects of the invention are as follows: a locking type quick-plug joint, the spherical body is arranged, it is convenient to connect the pipeline, realizes the soft connection, leaves a margin for the pipeline movement, and is not easy to be damaged, and the pipeline head is not easy to be damaged when it is active. It is easy to touch the inner wall of the rubber joint, does not affect the flow, and uses the arch to prevent deformation by external force; the setting of the throat hoop locking groove and the throat hoop is convenient for disassembly and assembly of the fixed pipeline; the setting of multi-channel water pressure buffer sealing protrusions can slow the seepage Leakage pressure, the first water pressure is large, the second is very small, and the third is reduced to zero to prevent leakage; the water pressure buffer sealing protrusion adopts an arc-shaped mouth suction cup structure, which makes the fixing more tightly sealed.

Detailed ways

Example 1

As shown in Figure 1-7, a locking type quick-plug joint includes an integrally formed spherical body 1 and a water pipe connection end 2. The spherical body 1 and the water pipe connection end 2 are integrally formed with nitrile rubber. The spherical body is designed with arches. The shape prevents external force from being deformed. The water pipe connection end 2 is provided with a throat hoop locking groove 3, and a throat hoop 4 is clamped in the throat hoop locking groove 3. The throat hoop 4 is an existing product in the market, and the water pipe The inner wall of the connection end 2 is provided with a plurality of water pressure buffer sealing protrusions 5, the water pressure buffer sealing protrusion 5 is integrally formed by the mold and the water pipe connection end 2, and two contact ends are provided on the water pressure buffer sealing protrusion 5 6. An arc-shaped mouth 7 is provided on the water pressure buffer sealing protrusion 5 in the middle of the two contact ends 6, and the arc-shaped mouth suction cup structure is adopted to make the fixing more sealed and firm, and a water pipe is clamped in the water pipe connection end 2 8. The contact end 6 is in contact with the outer wall of the water pipe 8 .

The distance between two adjacent water pressure buffer sealing protrusions 5 is equal and is 0.3-0.6CM.

The water pressure buffer sealing protrusions 5 are not less than 3 to slow the leakage water pressure. The first water pressure closest to the spherical body is relatively large, the second outward water pressure is very small, and the outermost third Reduced to zero, effectively preventing leakage.

As shown in Figure 5, after the water pipe 8 is inserted into the water pipe connecting pipe 2, there is a margin between the front end of the water pipe 8 and the inner wall of the spherical body, and it does not contact the inner wall of the spherical body, leaving a margin for the movement of the water pipe, which is not easy to be damaged. , and when it is active, the water pipe head is not easy to touch the inner wall of the spherical body, which does not affect the flow.

This technical solution only lists the form of tee, but direct, elbow, cross, etc. adopt the same connection and sealing structure, which also belongs to the scope of protection of this technical solution. When connecting large-diameter pipes, multiple throats can be used. The hoop is fixed and locked.

Specific usage: Insert the water pipe into the water pipe connection end 2, lock the hose clamp, and fix the water pipe. When the water pipe needs to be removed, just loosen the hose clamp and take out the water pipe. In the locking type quick-plug joint of this embodiment, the spherical body is arranged to facilitate the connection of pipelines, realize soft connection, leave a margin for pipeline movement, and is not easy to be damaged, and the pipeline head is not easy to touch when moving. The inner wall of the rubber joint does not affect the flow, and uses the arch to prevent deformation due to external force; the setting of the throat hoop locking groove and the throat hoop is convenient for disassembly and assembly of the fixed pipeline; the setting of multiple water pressure buffer sealing protrusions reduces the leakage water pressure , the first water pressure is large, the second is very small, and the third is reduced to zero to prevent leakage; the water pressure buffer sealing protrusion adopts an arc-shaped mouth suction cup structure, which makes the fixation more tightly sealed.
