Embodiment Construction
[0007] Now refer to the attached figure 1 In combination with the embodiments, the description is as follows: The folding fastener of the present invention includes a fastener A1, a nut 2, a bolt 3, a fastener B4, a hinge pin B5, a center plate 6 and a hinge pin A7. The center plate 6 is the centering piece of the folding fastener of the present invention. It has a triangular plate-shaped structure as a whole. The triangular plate-shaped structure mentioned here is not intended to be such a restriction. It is also possible to adopt other geometric forms that allow strength, but In terms of meeting the requirements of strength and saving raw materials, it is better to adopt a triangular plate structure. At one of the corners of the center plate 6, a roll hole is provided, which is connected to the fastener A1 through a hinge pin A7; at the other corner of the center plate 6, a roll hole is also provided, which is connected to the buckle through a hinge pin B5 The fitting B4 is ...

Abstract
The invention relates to a folding fastener which comprises a fastener A, a nut, a bolt, a fastener B, a hinged pin B, a center plate and a hinged pin A. The center plate is a center part and is integrally of a set square-shaped structure. A coil hole is arranged at the position of one angle of the center plate and is connected with the fastener A through the hinged pin A. A coil hole is arranged at the position of another angle of the center plate and is connected with the fastener B through the hinged pin B. A through hole is arranged at the third angle of the center plate. The bolt is inserted in the through hole and is screwed down by the nut, so that the fastener A, the center plate and the fastener B are connected and fixed on the bolt, and thus, the lap joint or the connection fixing of beam frames is realized. In the invention, after being subjected to cold press molding, a steel plate is subjected to double rust protection treatment of purification and galvanization, so that the rust-proofing capability is greatly improved and the service life is long and is far longer than that of a common fastener; due to the adoption of a cold press folding technology, in the production process, the energy consumption is low and no pollution is generated; and the folding fastener has a simple overall structure, is convenient to operate and use and has high stability and high reliability.
Description
Technical field [0001] The present invention relates to fasteners, in particular to a folding fastener. Background technique [0002] At present, both urban and rural areas are paying more and more attention to environmental planning, such as urban landscape belts, municipal road isolation belts, guardrails, agricultural vegetable greenhouses, breeding greenhouses, fences, etc., usually metal pipes or solid metal strips are welded as support skeleton. Through practice, it is known that the use of metal pipe welding as a support frame for landscape belts, isolation belts, guardrails, vegetable greenhouses, farming greenhouses, fences, etc., has high cost, inconvenient transportation and installation, and is not beautiful, easy to rust, and requires long-term maintenance. , There are many defects. Chinese patent 95108858.0 discloses a quick-connect fastener. A pin lock is installed on a movable buckle plate, and long holes and through-slot holes are provided on the fastener body ...
