Detailed Description

The technical solution of the present invention will be further explained with reference to the following embodiments and accompanying drawings.

The first embodiment is as follows:

as shown in the figure, the utility model discloses a:

a tube body 90100;

the snap ring 90200 comprises a first snap ring 90201, a second snap ring 90202 and a third snap ring 90203, is arranged at one end of the pipe body 90100, and is distributed from the port direction of the pipe body 90100 to the center direction of the pipe body in the sequence of the first snap ring 90201, the second snap ring 90202 and the third snap ring 90203;

the clamping ring 90300 is arranged at the other end of the pipe body 90100 opposite to the clamping ring 90200, and the clamping ring 90300 is arranged at the other end of the pipe body 90100 opposite to the clamping ring 90200;

a U-shaped latch 90400.

A gap is formed between the first snap ring 90201 and the second snap ring 90202 to form a first clamping groove 90210, and the first clamping groove 90210 is used for arranging a sealing ring.

A gap is formed between the second snap ring 90202 and the third snap ring 90203 to form a second clamping groove 90220, the diameter of the bottom surface of the second clamping groove 90220 is larger than the outer diameter of the pipe body 90100, and the second clamping groove 90220 is used for being matched with a U-shaped bolt 90400.

Specifically, the utility model discloses simple structure, the dismouting is simple and convenient, and during the concrete installation, the water pipe size that can connect as required, the flexible choice sealing washer sets up in draw-in groove one 90210, inserts the back into the water pipe with snap ring 90200 one end of this hose adapter, and U-shaped bolt 90400 cooperates and inserts the jack that predetermines on the water pipe, and the U-shaped bolt 90400 card is gone into between draw-in groove two 90220, realizes fixing the effect on the water pipe of this hose adapter; this hose adapter is equipped with the one end of joint ring 90300 and is used for coupling hose, inserts the hose that is fit for the size with joint ring 90300 one end, and joint ring 90300 can make hose elastic deformation, reaches the effect that hose adapter and hose are firmly connected.

Example two:

the difference between the second embodiment and the first embodiment is that the diameters of the first snap ring 90201 and the second snap ring 90202 are the same, the width of the first snap ring 90201 is larger than that of the second snap ring 90202, the diameter of the third snap ring 90203 is larger than that of the first snap ring 90201 and that of the second snap ring 90202, and the width of the third snap ring 90203 is the same as that of the second snap ring 90202.

Specifically, the diameters of the first snap ring 90201 and the second snap ring 90202 are the same, so that the sealing ring arranged in the first snap groove 90210 can be stressed in a balanced manner, and the problems that stress concentration is caused due to unbalanced stress on two sides, mechanical damage is caused to the sealing ring, and finally the sealing performance is invalid are solved; the diameter of the snap ring III 90203 is larger than that of the snap ring I90202 and that of the snap ring II 90202, so that the seal ring is covered from the outside of the water pipe, the corrosion of external environmental factors to the seal ring is prevented, and the service life of the seal ring is prolonged; the width of the second snap ring 90202 is equal to that of the third snap ring 90203, the width of the second snap ring 90202 is larger than that of the first snap ring 90201, the strength of the second snap ring 90220 is enhanced, the strength of matching with the U-shaped bolt is improved, and the firmness of connection with a water pipe is improved.

Example three:

the difference between the third embodiment and the first embodiment is that the diameter of the snap ring 90300 gradually decreases from the center of the tube 90100 to the end, the minimum diameter is the same as the outer diameter of the tube 90100, so that the outer side surface of the snap ring 90300 forms an inclined ring surface, and the surface of the snap ring 90300 facing the center of the tube 90100 is an arc surface.

Specifically, the outer side surface of the clamping ring 90300 is an inclined ring surface, so that when the hose is connected, the elastic deformation of the hose can be gradual, and the hose is convenient to mount; the surface of clamping ring 90300 to body 90100 central direction is the arc surface, can make this hose adapter of elastic deformation's hose more laminating, also can make the hose after the connection when receiving the stress of pulling out the direction, not fragile hose.
