Description

Technical Field

[0001] The utility model relates to the technical field of hail net installation, and specifically, to a wire connector for a net piece of a hail net. Background Art

[0002] A hail net is a protective facility used to prevent hail from damaging crops. It is generally made of polyvinyl chloride material and, through special treatment, chemical additives such as anti-aging agents and ultraviolet absorbers are added to enhance its durability and resistance to adverse weather. The hail net is usually made into a net structure through a wire drawing process, having a relatively large tensile strength, heat resistance, water resistance, and corrosion resistance. At the same time, it is also easy to age-resistant, non-toxic and odorless, and easy to dispose of after being discarded.

[0003] During the installation of the hail net, ropes are usually used for binding, and the ends of the ropes are fixed to the vertical poles, so that the hail net is located above the crops.

[0004] In the patent with the publication number of CN 206744075 U, a wire connector for a net piece of a hail net is disclosed, which includes a first clamping plate, a second clamping plate, and a connecting strip. The first clamping plate and the second clamping plate are connected by the connecting strip, and the connecting strip is bendable; a plurality of clamping grooves are processed on the first clamping plate, and a plurality of tapered barbs are arranged on the second clamping plate. A clamping point is formed by vertically and incompletely cutting from the tapered bottom surface of the tapered barb; the first clamping plate and the second clamping plate are clamped through the clamping point and the clamping groove. The utility model can effectively connect the net piece and the wire, and can realize the stable fixation of the net piece even in bad weather. At the same time, the wire connector for the net piece of the utility model is an integrated structure, with simple operation, detachable, and strong practicability.

[0005] When the above device is used, the two groups of clamping plates are combined with each other through the tapered barbs, the hail net is fixed within the clamping plates, and the steel wire rope is placed at the connection for binding. This makes the device a disposable tool, and it can only be damaged during disassembly, which is not environmentally friendly and energy-saving. Moreover, the above device fails to stably fix the steel wire rope, and the steel wire rope is prone to shaking, which may lead to the instability of the hail net.

[0006] Regarding the problems in the related art, no effective solution has been proposed yet. Content of the Utility Model
