The present invention is described in detail below in conjunction with the drawings.

[0021] Example 1

[0022] In Example 1 of the present application, a hose connector comprises a connector body 1 and two outer covers 2, the connector body 1 is penetrated by a water flow channel 3, both ends of the outer wall of the connector body 1 are respectively provided with annular bosses 8, the outer periphery of the annular boss 8 is provided with a first tightening structure, the two outer covers 2 are respectively threadedly sleeved on the two ends of the outer wall of the connector body 1, the outer cover 2 is provided with a through hole 5, the two ends of the connector body 1 are respectively penetrated by the through holes 5 of the two outer covers 2, the inner wall of the through hole 5 is provided with a second tightening structure, the first tightening structure cooperates with the second tightening structure to abut and tighten the hose; the first tightening structure is a boss external thread structure 4 or an annular raised sealing structure; the annular raised sealing structure can be an annular raised sealing rubber ring or an annular raised sealing hard rubber strip; the second tightening structure is an internal thread tightening structure 6, the internal thread tightening structure 6 is used to cooperate with the boss external thread structure 4 to abut and clamp the hose. Specifically, the utility model has a novel structure and an ingenious design. When in use, the hose is inserted into the outer periphery of the annular boss 8 at both ends of the connector body 1, and then the annular boss 8 is extended to the outer periphery to press against the inner wall of the hose to prevent the hose from loosening and falling off. At the same time, the boss external thread structure 4 is used to improve its pressing effect on the inner wall of the hose to play an anti-slip role; further, the rotating outer cover 2 is twisted and moved toward the ends close to the two ends of the connector body 11, so that the internal thread pressing structure 6 presses against the outer wall of the hose, so that the second pressing structure strengthens the pressing strength against the outer wall of the hose, improves the pressing effect against the outer wall of the hose, and makes the inner and outer walls of the hose clamped at the same time to form a tight sealing connection, thereby preventing the hose from loosening, having a reliable structure, and making the hose difficult to fall off, with good tightness and not easy to leak.

[0023] In the embodiment of the present application, both ends of the outer wall of the joint body 1 are further provided with a joint external thread structure 10, and the inner wall of the outer cover 2 is further provided with an outer cover internal thread structure 9, and the joint external thread structure 10 is threadedly connected with the outer cover internal thread structure 9. Specifically, under the above arrangement, the threaded connection between the outer cover 2 and the pipe body can be facilitated, the operation is convenient, and the outer cover 2 can be prevented from falling off.

[0024] In the embodiment of the present application, the joint external thread structure 10 is provided with a plurality of anti-shrinkage grooves 11 at equal intervals. Specifically, under the above arrangement, the joint body 1 and the joint external thread structure 10 are conveniently integrally injection molded to avoid shrinkage affecting the product structure.

[0025] In the embodiment of the present application, a limit grip portion 7 is provided in the middle of the outer wall of the connector body 1, and the limit grip portion 7 is integrally formed with the connector body 1. Specifically, the limit grip portion 7 can be convenient for operators to hold and work; at the same time, the two outer covers 2 are symmetrically arranged about the limit grip portion 7, and can respectively lock the hoses inserted into the two ends of the outer wall of the connector body 1.

[0026] In the embodiment of the present application, the annular boss 8 is integrally formed with the joint body 1. Specifically, the structure has high strength, good structural integrity, and is not easily deformed.

[0027] In the embodiment of the present application, the thread rotation direction of the boss external thread structure 4 and the thread rotation direction of the internal thread abutting structure 6 can be the same or opposite. Preferably, the thread rotation direction of the boss external thread structure 4 is opposite to that of the internal thread abutting structure 6. Specifically, under this setting, when the outer cover 2 rotates to the boss external thread structure 4, the boss external thread structure 4 abuts against the inner wall of the hose, and the internal thread abutting structure 6 abuts against the outer wall of the hose. Since the thread rotation direction of the boss external thread structure 4 is opposite to that of the internal thread abutting structure 6, they act as a resistance in the opposite direction, and the hose will not be pushed back by the outer cover 2, further improving the stability of the hose locked on the connector body 1 and not easy to loosen. At the same time, since the boss external thread structure 4 abuts against the inner wall of the hose, the hose can be inserted into the two ends of the connector body 1 in a rotating manner, which is more convenient and simple.

[0028] In the embodiment of the present application, the outer wall of the outer cover 2 is provided with anti-slip grooves 12. Specifically, under the above arrangement, it is possible to prevent the operator from slipping, thereby improving the reliability and stability of use.

[0029] In the embodiment of the present application, the two outer covers 2 are penetrated, and the cross section of the internal threaded clamping structure 6 can be arranged in a conical shape, which is beneficial to improve the effect of clamping the hose.

[0030] When the embodiment of the present application is used, the hose is inserted into the annular bosses at both ends of the connector body 1. When the hose is inserted tightly, the limiting gripping portion 7 of the connector body can be grasped to rotate the hose. The hose is screwed into the internal threaded clamping structure 6 of the outer cover 2 through the threaded action of the boss external thread structure 4 of the annular boss 8, and then the outer cover 2 is rotated backward. The outer cover 2 rotates backward under the cooperation of the connector external thread structure 10 of the connector body 1 and the external thread structure 9 of the outer cover, and the internal threaded clamping structure 6 of the outer cover 2 clamps the outer wall of the hose and retreats until the inner wall of the hose clamps the boss external thread structure 4 set on the inner side of the annular boss 8, so that the inner wall and outer wall of the hose are clamped at the same time to form a tight sealing connection. To disassemble the hose, just unscrew the outer cover 2 in reverse so that the internal threaded structure 6 of the outer cover 2 is separated from the outer wall of the hose and the hose can be pulled out. If there is a lot of resistance when pulling out the hose, just hold the limiting grip 7 of the connector body 1 and rotate the hose in reverse. The hose will exit the connector body 1 under the action of the thread on the diameter of the annular boss 8.

[0031] Example 2

[0032] In Example 2 of the present application, one end of the connector body 1 can be used to connect to the hose, and the other end of the connector body 1 can be used to connect to the water gun connector to achieve the connection between the hose and the water gun; of course, the water gun connector can also adopt a structure with an internal thread on the inner wall, which is used to cooperate with the boss external thread structure 411 to achieve threaded connection.
