[0018] The following is a non-limiting detailed description of the technical solution of the present invention in conjunction with preferred embodiments and their accompanying drawings. Obviously, the described embodiments are only a portion of the embodiments of the present invention, and not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0019] See also Figure 1-3The utility model provides a technical solution: a telescopic barrel of a high-pressure water gun, comprising a supporting tube 1, one end of the supporting tube 1 is fixedly connected to a water pipe joint 2, the other end of the supporting tube 1 is fixedly connected to a first sealing block 3, the outer wall of the supporting tube 1 is movably connected to a movable tube 4, one end of the movable tube 4 is fixedly connected to a water gun joint 5, the other end of the movable tube 4 is fixedly connected to a positioning block 6, the outer wall of the water pipe joint 2 is fixedly connected to a return spring 7, one end of the return spring 7 is fixedly connected to a movable block 8, and the outer wall of the movable block 8 is fixedly connected to a second sealing block 9. By arranging the supporting tube 1, the water pipe joint 2, the first sealing block 3, the movable tube 4, the water gun joint 5, the positioning block 6, the return spring 7, the movable block 8 and the second sealing block 9, it is convenient to perform telescopic adjustment, thereby making the water gun more convenient in use, solving the problem that the length of the water gun cannot be adjusted when in use, resulting in limited flushing, meeting people's work needs, and worthy of popularization and use.

[0020] Furthermore, the outer wall of the support tube 1 is provided with threads, and the threads on the outer wall of the support tube 1 engage with the threads on the inner wall of the movable tube 4, which facilitates sliding of the movable tube 4 through the threaded connection after rotation, thereby facilitating telescopic adjustment of the length.

[0021] Furthermore, the first sealing block 3 is made of elastic rubber material, and the first sealing block 3 is tightly fitted to the inner wall of the movable tube 4 , which facilitates sealing through the first sealing block 3 .

[0022] Furthermore, the positioning block 6 is a “concave”-shaped structure, and the positioning block 6 and the second sealing block 9 are engaged with each other, which facilitates positioning of the second sealing block 9 by the positioning block 6 .

[0023] Furthermore, the movable block 8 is an annular structure, and the movable block 8 forms a telescopic structure with the support tube 1 through the return spring 7, which facilitates the adaptive movement of the movable block 8.

[0024] Furthermore, the movable block 8 and the second sealing block 9 are distributed in a “T” shape, and the second sealing block 9 is made of elastic rubber material, which facilitates sealing through the second sealing block 9 .

[0025] When in use, first connect the water pipe connector 2 to the pipe of the high-pressure cleaning machine, and then connect the water gun connector 5 to the high-pressure water gun. When the length needs to be adjusted, turn the movable tube 4 to rotate so that the movable tube 4 can slide while rotating through the threaded connection with the support tube 1, which is conducive to adjusting the overall length, that is, it is convenient to use it in places that are out of reach during flushing, and avoids the problem of inconvenience in taking due to excessive length, thereby improving the scope of application, and the self-locking effect of the threaded connection during length adjustment improves stability. At the same time, during length adjustment, the internal connection between the support tube 1 and the movable tube 4 is sealed by the first sealing block 3, and the elasticity of the reset spring 7 allows the movable block 8 to drive the second sealing block 9 to move elastically, and then the second sealing block 9 can maintain the engagement with the positioning block 6, and then the external connection between the support tube 1 and the movable tube 4 is sealed, thereby improving the sealing effect after length adjustment and preventing leakage.
