Detailed Description
The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.
Referring to fig. 1 to 2, a telescopic tube includes: an outer tube 100, an inner tube 200 and a locking device; the outer pipe is provided with a cavity for accommodating the inner pipe; the outer surface of the inner pipe is provided with a plurality of stop grooves 210 along the axial direction; the locking device is fixed on the outer tube, and the locking device comprises: a button cover 310, a button 320, a button reset element 330, a slider 340, a slider reset element 350, and a needle roller 360; one end of the slide block resetting element props against the inner side of the button cover, and the other end of the slide block resetting element props against one end of the slide block; one end of the sliding block, which is far away from the sliding block resetting element, is provided with an inclined plane 341, and the lower end surface of the sliding block is provided with a roller pin receiving groove 342; the button is arranged on the upper end face of the button cover, a spring sleeve rod 321 extends from the lower end face of the button, and the button reset element is sleeved on the spring sleeve rod;
when the button is pressed, the spring sleeve rod abuts against the inclined surface to push the sliding block to move, the roller pins leave the stop grooves and enter the roller pin accommodating grooves to form an unlocking state, and when the button is released, the sliding block leaves the roller pin accommodating grooves and enters the stop grooves under the action of the restoring force of the sliding block resetting element to form a locking state.
In one embodiment, a sleeve 400 is provided on a side of the outer tube adjacent to the inner tube.
In one embodiment, the button return element is a spring.
In one embodiment, the slider return element is a spring.
In one embodiment, the locking device is fixed to the outer tube by screws.
The utility model has the advantages that:
by pressing and loosening the button, the telescopic pipe is stretched and locked, and the operation is convenient.
Referring to fig. 3 to 6, the operation principle is as follows:
the spring tightly pushes the sliding block towards the right direction, the sliding block tightly pushes the button through the inclined plane of the sliding block, the needle roller falls into the stop groove of the inner tube of the telescopic tube at the moment, the sliding block at the upper side just pushes the needle roller, and at the moment, the inner tube is locked and cannot be stretched;
when the button is pressed down, the spring sleeve rod abuts against the inclined surface to push the sliding block to move, the roller pins leave the stop grooves and enter the roller pin accommodating grooves to form an unlocking state, and the inner pipe can be freely stretched.
The above-mentioned embodiments are merely preferred embodiments for fully illustrating the present invention, and the scope of the present invention is not limited thereto. Equivalent substitutes or changes made by the technical personnel in the technical field on the basis of the utility model are all within the protection scope of the utility model. The protection scope of the present invention is subject to the claims.
