Description

Technical Field

[0001] The utility model relates to the field of washbasin hooks, in particular to a telescopic washbasin hook. Background Art

[0002] The washbasin hook can be used to hang the washbasin and make it suspended in the air. CN 220174992 U discloses a retractable washbasin hook, including: a base, including a connected base plate and a hook, the base plate is provided with a slide groove facing away from the hook opening, and a one-way buckle extends in the direction of the hook at the end of the slide groove away from the hook; a movable stopper, including a connected slide plate and a bending baffle, the slide plate is slidably matched with the slide groove, the bending baffle is located at the end of the slide plate away from the hook, there is a hanging space between the bending baffle and the hook, and a limiting convex body is provided at the end of the slide plate close to the hook, and the one-way buckle abuts against the limiting convex body after the slide plate slides a certain distance away from the hook. The movable stopper can be adapted to washbasins of more specifications and sizes by telescopically sliding through the cooperation of the slide plate and the slide groove. The one-way buckle in the above structure is an inner buckle, which is convenient for abutting against the upper surface of the limiting convex body. When the movable stopper is slid downward onto the base, the raised limiting convex body on its back side will squeeze and deform the one-way buckle outward. When the movable stopper slides upward off the base, the one-way buckle on the upper end of the base needs to be tilted outward to make it leave the upper end of the limiting convex body, so that the movable stopper can slide out of the base without hindrance. The disassembly and assembly process is relatively complicated. After multiple outward deformations, the plastic one-way buckle is easy to break, and the inner buckle effect is not good, and it cannot form a good abutment against the upper surface of the limiting convex body. And when the plastic one-way buckle is bent inward to form an inner buckle, it is also easy to deform and break. Plastic one-way buckles are easy to deform and damage. Utility Model Content
