Abstract
The invention discloses a fastener, which belongs to the technical field of machinery. The fastener comprises two butt-jointed half ring-shaped bodies, and is characterized in that a stud pin and a stud pin hole matched with the stud pin are respectively formed on the two end surfaces of the half ring-shaped bodies; the two half ring-shaped bodies are clamped and in butt joint with each other by the stud pin and the stud pin hole; and reinforcing ribs are arranged on the inner side walls of the half ring-shaped bodies. The fastener has a simple and reasonable structure, is high in repeated utilization ratio and convenient to assemble and disassemble, and can be widely applied to connection of scaffolds or stud bodies.
Description
Technical field
The present invention relates to a kind of fastener, be specially adapted to the connection between the cylindrical body, belong to field of mechanical technique.
Background technique
At present, fastener form and the kind used on the market are a lot, but have different drawbacks mostly, and fastener receives bump when reinforcing, the easy fracture of extruding causes fastener to scrap, and has increased cost, and recycling rate of waterused is low.Therefore, press for a kind of safe in utilization, fastener that structural stability is firm is provided.
Summary of the invention
The objective of the invention is deficiency, the fastener that a kind of connection is more fastening, structural stability is firm is provided to above-mentioned existing technology.
The objective of the invention is to realize: a kind of fastener through following technological scheme; Two semi-annular shape bodies that comprise butt joint; It is characterized in that; The column pin hole that the two ends end face of said semi-annular shape body is respectively equipped with pin or is complementary with pin, two semi-annular shape bodies are through pin, column pin hole engaging butt joint, and the madial wall of said semi-annular shape body is provided with stiffening rib.
Said semi-annular shape body two ends are respectively equipped with bolt connecting hole.
The present invention is installed in two cylindrical joints in use, after two semi-annular shape bodies connect through pin, column pin hole, re-uses bolt and passes fixing two the semi-annular shape bodies of bolt connecting hole, makes that like this installation is more firm; Stiffening rib on two semi-annular shape body madial walls make fastener be squeezed, easy-rupturing not when clashing into, more solid.The present invention is simple and reasonable, and recycling rate of waterused is high, and easy accessibility can be widely used in the connection of scaffold or cylinder.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Among the figure: 1 semi-annular shape body, 2 pins, 3 column pin holes, 4 stiffening ribs, 5 bolt connecting holes.
Embodiment
A kind of fastener; Comprise two semi-annular shape bodies 1; The column pin hole 3 that the two ends end face of semi-annular shape body is respectively equipped with pin 2 or is complementary with pin; Two semi-annular shape bodies are through pin, column pin hole engaging butt joint, and two semi-annular shape body two ends are respectively equipped with bolt connecting hole 5, and it is fastening firmly with fastener that bolt passes bolt connecting hole.The madial wall of semi-annular shape body is provided with stiffening rib 4.
Claims (2)
