[0022] like Figure 1-5 The utility model provides a novel telescopic rod for a sprayer, comprising an outer sleeve 1, an inner sleeve 2 with one end placed inside the outer sleeve 1, a telescopic joint 3 is detachably provided on the outer periphery of one end of the outer sleeve 1 close to the inner sleeve 2, a handle joint 4 is detachably provided on the outer periphery of one end of the outer sleeve 1 away from the inner sleeve 2, and a nozzle joint 5 is detachably provided on the inner periphery of the inner sleeve 2 away from the outer sleeve 1.

[0023] It is connected to the outer sleeve and the inner sleeve through the telescopic joint. The handle joint is used to connect the handle and the outer sleeve, and the nozzle joint is used to connect the nozzle and the inner sleeve. When any connection position is damaged, the new part can be easily replaced by disassembling and replacing the joint at the corresponding position. There is no need to replace the entire part, thus reducing the replacement cost.

[0024] The outer diameter of the inner sleeve is smaller than the inner diameter of the outer sleeve to ensure that the inner sleeve can be inserted into the outer sleeve.

[0025] It is worth mentioning that the expansion joint, handle joint and nozzle joint are all interference fit with the pipe end to ensure the sealing of the connection.

[0026] Preferably, a positioning sleeve 6 is sleeved along the outer circumference of the inner sleeve 2 , and a sealing ring 7 is provided between the positioning sleeve 6 and the expansion joint 3 .

[0027] Specifically, since the inner sleeve needs to be telescopically moved relative to the outer sleeve, a sealing ring is provided to seal the connection between the outer sleeve and the inner sleeve to improve the water leakage prevention effect. At the same time, the position of the sealing ring is limited by a positioning sleeve to increase the stability of the sealing ring.

[0028] Preferably, a movable sleeve 8 is provided on the outer periphery of the positioning sleeve 6, and the movable sleeve 8 can move along the axial direction of the inner sleeve 2, and the inner wall of the movable sleeve 8 is provided with a conical structure, so that when the movable sleeve 8 approaches the telescopic joint 3, the movable sleeve 8 presses and limits the outer periphery of the positioning sleeve 6.

[0029] Specifically, when the inner sleeve needs to be telescopically moved relative to the outer sleeve, the movable sleeve moves away from the position of the telescopic joint, and after the inner sleeve is moved, the movable sleeve approaches the telescopic joint. At this time, the outer periphery of the positioning sleeve is pressed by the conical structure of the inner wall of the movable sleeve, so that the positioning sleeve clamps the outer periphery of the inner sleeve and limits the position of the sealing ring, so that the relative position of the inner sleeve and the outer sleeve is stable.

[0030] Preferably, one end of the expansion joint 3 close to the movable sleeve 8 has a threaded extension section 9, and the movable sleeve 8 is provided with an internal thread along the circumferential direction, so that the movable sleeve 8 and the expansion joint 3 are threadedly matched.

[0031] Specifically, when the movable sleeve moves closer to or farther away from the telescopic joint, the movable sleeve can be rotated to match the threaded connection to allow the movable sleeve to move axially, thereby conveniently controlling the clamping or loosening of the positioning sleeve on the inner sleeve.

[0032] Preferably, a plurality of positioning pieces 10 are distributed at intervals along the circumferential direction at one end of the positioning sleeve 6 away from the expansion joint 3 , and when the movable sleeve 8 presses the positioning sleeve 6 , the plurality of positioning pieces 10 are tightened toward the position of the inner sleeve 2 .

[0033] Specifically, when the movable sleeve approaches the expansion joint, the conical structure inside it presses the outer periphery of the positioning sleeve, and then presses each positioning piece, so that the positioning piece is tightened toward the inner sleeve, thereby improving the limiting effect of the positioning sleeve on the inner sleeve.

[0034] Preferably, a limiting ring groove 11 is provided on one side of the positioning sleeve 6 close to the sealing ring 7, and the sealing ring 7 is buckled in the limiting ring groove 11, so that the relative positions of the sealing ring and the positioning sleeve are sufficiently stable.

[0035] Preferably, the expansion joint 3, the handle joint 4 and the nozzle joint 5 are all provided with multiple layers of slots 12 in the axial direction, and the diameters of the multiple layers of slots 12 decrease step by step.

[0036] Specifically, by using multiple layers of slots with different diameters, pipe fittings with different diameters can be matched with each joint, thereby improving the scope of application of the solution.

[0037] The present utility model is not limited to the above-mentioned optimal implementation mode. Anyone can derive other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in the shape or structure, all those having the same or similar technical solutions as the present application fall within the protection scope of the present utility model.
