Abstract
Description
Technical Field
[0001] This utility model relates to the field of hail net technology, specifically to a hand-operated hail net retraction and deployment device. Background Technology
[0002] Hail suppression netting is a mesh fabric made of polyethylene with added anti-aging and UV-resistant chemical additives as the main raw material, which is produced by drawing into fibers. It has advantages such as high tensile strength, heat resistance, water resistance, corrosion resistance, aging resistance, non-toxicity, odorlessness, and easy disposal of waste.
[0003] Currently available hail protection nets are usually fixed to a support frame with wire and then installed above the fruit trees. However, the wire fixing method makes it difficult to quickly fold up or unfold the hail protection net during use, which makes it inconvenient to put away and unfold the net.
[0004] To address the aforementioned problems, this application proposes a hand-operated hail net retraction and deployment device. Utility Model Content
[0005] To address the problems in related technologies, this utility model provides a hand-operated retraction and deployment device for hail nets, which enables the hail nets to be quickly retracted or extended during use via the retraction and deployment components, thereby improving the convenience of retraction and deployment during use.
[0006] Therefore, the specific technical solution adopted by this utility model is as follows:
[0007] A hand-operated hail net retraction device includes a bracket, a pull rope, and a retraction assembly. The pull rope is installed in the inner cavity of the bracket, and the hail net assembly is installed between the two pull ropes. A part of the retraction assembly is installed at the right end of the hail net assembly.
[0008] The retraction and deployment assembly includes a limiting block, which is fixedly installed on the right end of a part of the hail protection net assembly. A pull ring is installed at the bottom end of the limiting block, which is used in conjunction with one end of a multi-functional pull rod. A limiting hole is opened on the limiting block, which is used in conjunction with a limiting groove on the crossbar inside the bracket. A limiting post is threadedly connected to the bottom wall of the limiting groove.
[0009] As a further embodiment of this utility model, the hail protection net assembly includes a net body, a fixed strip is fixedly connected to the left end of the net body, the fixed strip is installed on the side wall of the bracket by fixing bolts, and a movable strip is fixedly connected to the right end of the net body.
[0010] As a further embodiment of this utility model, a limit block is installed at the right end of the moving bar, and the front and rear ends of the net body are slidably connected to the pull rope through a ring.
[0011] As a further embodiment of this utility model, the hexagonal end of the multifunctional pull rod is used in conjunction with the internal hexagonal hole at the bottom of the limiting post, and the hook end of the other end of the multifunctional pull rod is used in conjunction with the hand pull ring.
[0012] As a further embodiment of this utility model, the upper end of the limiting post can be threadedly connected to the limiting hole.
[0013] As a further embodiment of this utility model, the multifunctional pull rod is placed on the side wall of the bracket via a hanger.
[0014] The beneficial effects of this utility model are as follows:
[0015] This invention utilizes a bracket, a pull rope, and a retraction / deployment assembly to work together. When the hail net needs to be deployed, the multi-functional pull rod on the mounting bracket is removed, the hook end is inserted into the pull ring, and then the net is pulled to the right via the limit block and moving bar. During this process, the rings at both ends of the net move along the pull rope until the limit block is inserted into the limit groove on the crossbar. Then, the multi-functional pull rod is removed, turned around, and the hexagonal end is inserted into the internal hexagonal hole at the bottom of the limit post. The limit post is then rotated via the multi-functional pull rod, causing the upper end of the limit post to threadedly connect with the limit hole on the limit block, thus fixing the limit block and allowing the net to be tightened. When the hail net needs to be retracted, the operation is the reverse of the deployment process. This device allows the hail net to be quickly retracted or deployed using the retraction / deployment assembly, thereby improving the convenience of deployment and retraction during use.
