The sliding sleeve 7 and the joint main body 2 form an elastic sliding fit structure, and the joint male head 9 forms a limiting locking mechanism by extruding the inner spring 14 and the joint main body 2 and the sliding sleeve 7. When the joint male head 9 and the joint main body 2 are inserted in place through the limiting locking mechanism, a contact sealing structure is formed between the sealing contact part 92 on the joint male head 9 and the first sealing ring 10. In particular, the amount of the solvent to be used,
the specific structure of the joint body 2 is as shown in fig. 4, a plurality of sliding grooves 21 and annular grooves 22 are respectively formed on the outer circumference of the joint body 2, the sliding grooves 21 are generally uniformly distributed around the outer circumference of the joint body 2, and the cross-sectional shape of each sliding groove 21 preferably adopts a tapered structure. The sliding groove 21 is provided with a locking body 3, and the locking body 3 is usually a steel ball. The specific structure of the sliding sleeve 7 is as shown in fig. 5, and a guide groove 71, a locking ring belt 72 and a limiting groove 73 are respectively formed in the hollow inner cavity of the sliding sleeve 7. As shown in fig. 2, the male joint 9 has a specific structure in which a catching groove 91 is formed on the outer circumference of one end of the male joint 9 and a seal contact portion 92 is formed on the other end of the male joint 9. In order to increase the mechanical strength and the service life of the male connection end 9, a shoulder 93 of conical design can be formed at one end of the male connection end 9, and a locking groove 91 can be formed on the shoulder 93.
Sliding sleeve 7 and connect between the main part 2 and form spring installation cavity 12 through spacing groove 73, spring installation cavity 12 in set up spring 6, sliding sleeve 7 and connect between the main part 2 and form elasticity sliding fit structure through spring 6. When the locking body 3 is clamped between the sliding groove 21 and the clamping groove 91 through the locking ring belt 72 on the sliding sleeve 7, the locking body 3, the sliding groove 21, the locking ring belt 72 and the clamping groove 91 form a limiting locking mechanism together. When the male connector 9 and the connector main body 2 are inserted in place through the limit locking mechanism, a contact sealing structure is formed between the sealing contact part 92 on the male connector 9 and the first sealing ring 10, as shown in fig. 3.
In order to facilitate the insertion operation between the male connector 9 and the connector body 2 and ensure that the male connector 9 is inserted in place, an inner guide sleeve 13 as shown in fig. 6 can be installed in the hollow inner cavity of the connector body 2, and a limit boss 131 is formed on the inner guide sleeve 13. The inner guide sleeve 13 is positioned between the inner spring 14 and the locking body 3, and a sliding fit structure is formed between the inner guide sleeve 13 and the joint main body 2. When the limit locking mechanism is unlocked, as shown in fig. 2, the inner spring 14, the inner guide sleeve 13 and the sliding sleeve 7 together limit the locking body 3 in the sliding groove 21 of the joint main body 2.

The working principle of the inner spring type quick connector is as follows:
before the joint male head 9 is not inserted into the joint main body 2 assembly, as shown in fig. 2, the inner guide sleeve 13 is pressed against the locking body 3 through the limiting boss 131 under the elastic force of the inner spring 14, and meanwhile, the sliding sleeve 7 covers the locking body 3 through the guide groove 71, so that the locking body 3 can be limited in the sliding groove 21 on the joint main body 2 by the inner spring 14, the inner guide sleeve 13 and the sliding sleeve 7 together, so as to limit the leftward movement of the locking body 3 relative to the joint main body 2, and meanwhile, the locking body 3 can limit the rightward movement of the inner guide sleeve 13 relative to the joint main body 2, thereby achieving a stable state and preventing the locking body 3 from falling out of the joint main body 2.
During the insertion of the male connector 9 into the connector body 2, as shown in fig. 3, the shoulder 93 on the male connector 9 presses the inner guide sleeve 13, causing the inner guide sleeve 13 to compress the inner spring 14 and move leftwards relative to the connector body 2, and causing the locking body 3 to move along the sliding groove 21 towards the outer wall of the connector body 2; when the locking body 3 is separated from the inner guide sleeve 13 and is inserted with the joint male head 9 continuously until the locking body 3 is clamped between the sliding groove 21 and the clamping groove 91 through the locking ring belt 72 on the sliding sleeve 7, the locking body 3, the sliding groove 21, the locking ring belt 72 and the clamping groove 91 jointly form a limiting locking mechanism, and therefore locking between the joint main body 2 assembly and the joint male head 9 is achieved.
When the joint male head 9 and the joint main body 2 need to be unlocked, as shown in fig. 2 and fig. 3, the sliding sleeve 7 only needs to be pulled leftwards relative to the joint main body 2 by hand until the locking ring belt 72 on the sliding sleeve 7 is separated from the locking body 3, and at the moment, the limiting locking mechanism is in an unlocking state, and the joint male head 9 can be directly pulled out from the joint main body 2.
In the process of repeated inserting and extracting operations of the male connector 9 relative to the connector main body 2, in order to ensure the sealing performance between the sealing contact part 92 on the male connector 9 and the first sealing ring 10 and the second sealing ring 11 respectively and further improve the reliability of the sealing performance of the quick inserting connector, a spacer ring 4 and a clamping ring 5 can be additionally arranged in the hollow inner cavity of the connector main body 2, the spacer ring 4 and the clamping ring 5 are usually fixedly arranged in the hollow inner cavity of the connector main body 2 in an interference fit mode, the spacer ring 4 is arranged between the second sealing ring 11 and the first sealing ring 10, and the clamping ring 5 is arranged between the second sealing ring 11 and the sliding groove 21. Generally, the cross-sectional shape of the collar 5 is designed into a Y-shaped structure, a positioning groove 23 is formed in the hollow inner cavity of the connector main body 2, and a clamping and fixing structure is formed between the Y-shaped structure on the collar 5 and the positioning groove 23, as shown in fig. 2-4; when the male connector 9 and the male connector body 2 are inserted into place through the limit locking mechanism, a contact sealing structure is formed between the spacer ring 4 and the sealing contact portion 92 on the male connector 9, and a contact sealing structure is also formed between the collar 5 and the sealing contact portion 92 on the male connector 9, as shown in fig. 3.
After the structural design is adopted, the setting positions of the first sealing ring 10 and the second sealing ring 11 in the hollow inner cavity of the joint main body 2 can be well limited by arranging the spacer ring 4 and the clamping ring 5, in the process of repeatedly inserting and pulling the joint male head 9 relative to the joint main body 2, the first sealing ring 10 and the second sealing ring 11 can be effectively prevented from axially shifting relative to the joint main body 2, so that the compression amount of the first sealing ring 10 and the second sealing ring 11 can be controlled more accurately, thereby ensuring the sealing performance between the sealing contact part 92 on the joint male head 9 and the first sealing ring 10 and the second sealing ring 11 respectively, moreover, the sealing contact part 92 on the joint male head 9 can form a contact sealing structure with the spacer ring 4 and the clamping ring 5 respectively, therefore, the quick connector can form a quadruple sealing structure, and the sealing reliability of the quick connector is greatly improved.
The utility model discloses when the installation, directly will connect male 9 to peg graft into and connect main part 2, after connecting male 9 and peg graft in place, it will automatic locking with connecting between the main part 2.
