Description

Technical Field

[0001] The utility model relates to the field of hooks, in particular to a plastic hook with adjustable length. Background Art

[0002] In daily life, hanging clothes, shoes, or other items requires hooks. Traditional hooks are usually fixed in length, which can be inconvenient in practice, especially when drying items of varying sizes or weights. To address this problem, adjustable-length plastic hooks have emerged on the market.

[0003] This type of hook consists primarily of a hook body, a connecting handle, a screw, and a threaded sleeve. The hook body is used to hang from a drying rod or rope, while the connecting handle is attached to the bottom of the hook body, and the screw is fixed to the surface of the connecting handle. The threaded sleeve fits over the screw and, by twisting it, moves along the screw, adjusting the overall length of the hook. This design allows the hook to be adjusted in length to accommodate items of varying sizes or weights.

[0004] However, in practice, traditional adjustable-length hooks still have some drawbacks. For example, heavy or bulky items can slip off the end of the thread sleeve, preventing them from drying. Furthermore, because the threads of the screw are exposed, they can wear or become damaged over time, shortening the hook's lifespan. Utility Model Content

[0005] The purpose of the utility model is to provide a plastic hook with adjustable length to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a plastic hook with adjustable length, comprising a suspension hook body, a connecting handle fixed to the bottom end of the suspension hook body, a screw fixed to the surface of the connecting handle, a wire sleeve threaded on the rod body of the screw, one end of the wire sleeve is rotatably connected to a hollow baffle, and a counterweight block is fixed to the bottom end of the hollow baffle.

[0007] Preferably, the screw rods are provided in plurality, and the plurality of screw rods are arranged and distributed with equal distances and sizes around the connecting handle as the central axis, and the wire sleeve is in a cylindrical structure.

[0008] Preferably, a screwing handle is fixed to one end of the wire sleeve close to the hollow baffle, and the screwing handle is a "U"-shaped piece. There are multiple screwing handles, and the multiple screwing handles are arranged in a circle with the wire sleeve as the central axis.

[0009] Preferably, a limiting groove is opened at one end of the wire sleeve, and the limiting groove is a spherical groove. A ball handle is rotatably connected inside the limiting groove. The diameter of the ball handle is larger than the slot diameter of the limiting groove, and one end of the ball handle is fixed on the surface of the hollow baffle.

[0010] Preferably, the hollow baffle is a square plate with a hollow interior, the bottom end of the hollow baffle is arc-shaped, the counterweight is a circular plate structure, and the counterweight is fixed on the arc surface of the bottom end of the hollow baffle.

[0011] Preferably, a limiting sleeve is sleeved on the rod body of the wire sleeve, the rod length of the limiting sleeve is smaller than the rod length of the wire sleeve, and one end of the limiting sleeve is fixed on the surface of the connecting handle.

[0012] Preferably, a guide groove is provided on the inner ring surface of the limit sleeve, which is an annular groove. The length of the guide groove is smaller than the length of the limit sleeve. A convex ring is integrally formed at one end of the wire sleeve close to the connecting handle, and the convex ring is slidably connected in the guide groove.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The length-adjustable plastic hook proposed in this utility model effectively prevents suspended items from slipping off the end of the threaded sleeve by adding a hollow baffle and a counterweight to the end of the threaded sleeve. The hollow baffle acts as a barrier, while the weight of the counterweight ensures that the hollow baffle remains perpendicular to the ground, enhancing the barrier effect. A stop sleeve is installed on the outside of the threaded sleeve, covering the exposed threaded portion of the screw. This way, the suspended item only contacts the stop sleeve or the threaded sleeve and does not directly contact the threaded portion of the screw, thereby reducing wear and damage to the screw and extending the service life of the hook.
