Description

Technical Field

[0001] The utility model relates to the technical field of folding hinges, in particular to an improved folding hinge for awnings and tents. Background Technique

[0002] A tent is a shed supported on the ground to shield against wind, rain, and sunlight and for temporary residence. It is mostly made of canvas, and together with the supporting things, it can be disassembled and transferred at any time. Tents are carried in the form of components and assembled on-site after arrival. Therefore, various components and tools are required.

[0003] Most of the existing awning tents are connected by means of hinges, and most of the hinges in the existing technology are assembled and welded between multiple components. During the processing process, there are many processing procedures, and the use of multiple components will increase costs. Content of the Utility Model

[0004] The purpose of the utility model is to provide an improved folding hinge for awnings and tents to solve the problem that most of the hinges in the existing technology are assembled and welded between multiple components. During the processing process, there are many processing procedures, and the use of multiple components will increase costs. To achieve the above purpose, the utility model provides the following technical solution: An improved folding hinge for awnings and tents, including a left support hinge. A right support hinge is arranged on one side of the left support hinge. A hinge shaft is welded at the connection of the front surfaces of the left support hinge and the right support hinge. Circular tubes are sleeved on both the upper and lower sides of the hinge shaft. An irregular through hole is opened on one side of the left support hinge, and a long through hole is opened on one side of the right support hinge. The upper and lower ends of the circular hinge shaft are of a compression type and can be sleeved into circular tubes of the same diameter, so that the circular hinge shaft can be directly placed flat at the center of the left and right support hinges and directly welded, thus greatly reducing the welding process.

[0005] Further preferably, a screw rod is arranged in the inner cavity of the long through hole. The screw rod penetrates through the long through hole and the irregular through hole. A nut is threadedly sleeved on one side of the outer side of the screw rod. The left and right hinges are respectively provided with an irregular through hole and a long through hole for sleeving the bolt hole. When there is no gap when the irregular through hole and the long through hole are butted, the screw rod does not need to be disassembled and directly slides to the fixed end for fixation by inertia through the irregular through hole.

[0006] Compared with the existing technology, the beneficial effects of the utility model are as follows:

[0007] In the utility model, the upper and lower ends of the circular hinge shaft are of a compression type and can be sleeved into circular tubes of the same diameter, so that the circular hinge shaft can be directly placed flat at the center of the left and right support hinges and directly welded, thus greatly reducing the welding process.

[0008] In the present utility model, the left and right hinges are respectively provided with a special-shaped through hole and a long-shaped through hole sleeve for inserting a bolt hole. When the special-shaped through hole and the long-shaped through hole are butted seamlessly, the screw rod can pass through the special-shaped through hole without being disassembled and directly slide to the fixed end for fixation by inertia.
