The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] Reference Figure 2 and Figure 3This utility model provides a plastic tube for easy connection, comprising: a first tube body 1, a connecting tube 2 fixedly connected to the upper surface of the first tube body 1 for connecting the first tube body 1 and a second tube body 3, a sliding groove 9 provided in the connecting tube 2 for sliding of an elastic column 4, a locking hole 10 provided on the connecting tube 2 for fixing the position of the elastic column 4, the locking hole 10 being located at one end of the sliding groove 9, the diameter of the locking hole 10 being longer than the width of the sliding groove 9, a second tube body 3 detachably connected inside the connecting tube 2, an elastic column 4 fixedly connected to the outer surface of the second tube body 3 for ensuring accurate and fixed position of the second tube body 3, the elastic column 4 being slidably connected to the sliding groove 9, and the elastic column 4 being movably connected to the locking hole 10.

[0023] Specifically, based on the elasticity of the elastic column 4, press the elastic column 4 and slide it into the groove 9 on the connecting tube 2. At the same time, the second tube 3 slides into the connecting tube 2. The elastic column 4 slides into the position of the locking hole 10 at the other end of the groove 9. Then, because of the elasticity of the elastic column 4, it pops out and is locked in place by the locking hole 10.

[0024] Reference Figure 1 , Figure 3 and Figure 4 The connecting pipe 2 has a slot 5 for placing the locking block 8 connecting structure. The inner surface of the slot 5 is fixedly connected to the mounting block 6 for installing the spring 7. The outer surface of the mounting block 6 is fixedly connected to the spring 7 for popping out the locking block 8 and applying a certain force. The other end of the spring 7 away from the mounting block 6 is fixedly connected to the locking block 8 for fixing the second pipe body 3. The upper end of the locking block 8 is inclined and rounded to facilitate the insertion of the second pipe body 3 into the locking block 8. The locking block 8 is movably connected to the second pipe body 3. The outer surface of the mounting block 6 is fixedly connected to the telescopic pipe 13. The other end of the telescopic pipe 13 is fixedly connected to the locking block 8 to prevent the locking block 8 from tilting and to ensure that the locking block 8 moves vertically in a straight line. The second pipe body 3 is detachably connected inside the connecting pipe 2.

[0025] Specifically, the second tube 3 is inserted into the connecting tube 2. By continuously pressing the second tube 3 until it contacts the first tube 1, the second tube 3 will squeeze the locking block 8. The spring 7 on the mounting block 6 applies force to the locking block 8, and the locking block 8 fixes and locks the position of the second tube 3. The sealing is completed by the first sealing ring 12 on the first tube 1 and the second sealing ring 11 on the second tube 3.

[0026] Specifically, a first sealing ring 12 is fixedly connected to the upper surface of the first tube 1 for sealing, and a second sealing ring 11 is fixedly connected to the lower surface of the second tube 3 for sealing. The second sealing ring 11 is movably connected to the first sealing ring 12. The materials of the second sealing ring 11 and the first sealing ring 12 are hydrogenated nitrile rubber, which are used to seal the first tube 1 and the second tube 3.

[0027] Working principle: When in use, press the elastic post 4 on the second tube body 3 to insert the elastic post 4 into the slide groove 9 on the connecting tube 2, and slide it in the slide groove 9 to the locking hole 10. Then, the elastic post 4 pops out in the locking hole 10 due to its elasticity. The locking hole 10 fixes the elastic post 4, thereby fixing the position of the second tube body 3. During the process of inserting the second tube body 3 into the connecting tube 2, it will squeeze the locking block 8. The spring 7 on the mounting block 6 pops out the locking block 8 and applies a certain force to the locking block 8. The locking block 8 fixes and locks the second tube body 3, completing the docking.

[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
