The technical scheme of the utility model is as follows: a waterproof connector comprises a connecting end and an inserting end, wherein the connecting end is cylindrical, a cylindrical groove is formed in one end of the connecting end inwards, a spring is arranged at the bottom of the groove of the connecting end, a first sealing ring is arranged at one end, away from the bottom of the groove of the connecting end, of the spring, a boss is arranged on the outer side wall of the end portion where the groove of the connecting end is located, a locking buckle is sleeved on the side wall of the connecting end, the inner diameter of the locking buckle is larger than or equal to the outer diameter of the boss on the side wall of the connecting end, the boss is arranged at one end of the locking buckle inwards, the boss of the locking buckle is attached to the outer wall of the connecting end, a second sealing ring is sleeved on the outer wall of the connecting end, the second sealing ring is located between the boss of the locking buckle and the boss of the connecting end, and an inner thread is arranged at one end, away from the boss, of the inner wall of the locking buckle;

the utility model discloses a sealing device, including the end that inserts, the end that inserts is the cylinder, inserts an end portion and sets up cylindrical recess, the outer wall that inserts the end is located no recess one end and sets up the external screw thread, insert the end outer wall and hug closely the external screw thread and set up the third sealing washer, the external diameter less than or equal to of inserting the end recess one end that inserts the end is the internal diameter of link recess, the external screw thread is mutually supported with the internal thread.

Furthermore, SIL silicon rubber sealing rings are adopted for the first sealing ring, the second sealing ring and the third sealing ring.

Furthermore, a stitch connecting hole is formed in the connecting end groove, and a stitch is arranged in the inserting end groove.

Further, the length of the external thread is larger than that of the internal thread.

Further, the surfaces of the internal thread and the external thread are provided with wear-resistant coatings.

The utility model has the advantages and positive effects that:

1. because use internal thread and external screw thread connection to insert end and link, make the grafting more firm, improve the stability of connecting, reduce outside influence.

2. Because the locking is detained and is sealed with the link adoption second sealing washer, has effectively improved the leakproofness, because link and the third sealing washer of end connection department use screw-thread fit that inserts prevent to take place the liquid seepage to the spring adds first sealing washer and provides the third layer sealed, and the spring still provides the locking for the cooperation of internal thread and external screw thread simultaneously, avoids taking place the landing and becoming flexible.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1-4:

a waterproof connector comprises a connecting end 1 and an inserting end 2, wherein the connecting end 1 is cylindrical, a cylindrical groove is formed in one end of the connecting end 1 inwards, a spring 4 is arranged at the bottom of the groove of the connecting end 1, a first sealing ring 5 is arranged at one end, away from the bottom of the groove of the connecting end 1, of the spring 4, a boss is arranged on the outer side wall of the end portion where the groove of the connecting end 1 is located, a locking buckle 3 is sleeved on the side wall of the connecting end 1, the inner diameter of the locking buckle 3 is larger than or equal to the outer diameter of a boss on the side wall of the connecting end 1, a boss is arranged inwards at one end of the locking buckle 3, the boss of the locking buckle 3 is attached to the outer wall of the connecting end 1, a second sealing ring 6 is sleeved on the outer wall of the connecting end 1, the second sealing ring 6 is located between the boss of the locking buckle 3 and the boss of the connecting end 1, and an inner thread 7 is arranged at one end, away from the boss, of the inner wall of the locking buckle 3;

insert end 2 and be the cylinder, insert 2 tip that the end sets up cylindrical recess, the outer wall that inserts end 2 is located no recess one end and sets up external screw thread 9, insert 2 outer walls that insert the end and hug closely external screw thread 9 and set up third sealing washer 8, the external diameter less than or equal to of the end that inserts 2 recess one end the internal diameter of 1 recess of link, external screw thread 9 and internal thread cooperate mutually.

The first sealing ring 5, the second sealing ring 6 and the third sealing ring 8 adopt SIL silicon rubber sealing rings.

Set up the stitch connecting hole in the 1 recess of link, set up the stitch in inserting 2 recesses.

The length of the external thread 9 is greater than the length of the internal thread 7.

The surfaces of the internal thread 7 and the external thread 9 are provided with wear-resistant coatings.

The working process of the example is as follows:

in the using process, the inserting end 2 is inserted into the connecting end 1, the end part of the inserting end 2 presses the first sealing ring 5 and the spring 4 to complete the first layer of sealing, then the locking buckle 3 is used for locking through the internal thread 7 and the external thread 9, so that the third sealing ring 8 of the insertion end 2 is tightly attached to the boss of the connecting end 1 to complete the second layer of sealing, the process of suspending the locking buckle 3 presses the boss of the locking buckle 3 and the boss of the connecting end 1 to press the second sealing ring 6, thereby completing the third layer of sealing, completing the last layer of sealing by threaded connection, increasing a locking force by the threaded connection due to the elasticity of the spring 4, avoiding the loosening of the threads, improving the stability of the structure, and simultaneously generating slight deformation of the sealing ring under the compression, thereby closely laminating the lateral wall of both sides, having improved whole sealed effect to SIL silicon rubber can also be able to bear or endure air ageing, has improved life.
