Problems solved by technology

[0002] In the prior art, there are many structures for connecting pipes through connecting fittings. The more common one is to insert the pipes into the connecting fittings, and then directly connect and fix the pipes and connecting fittings with fasteners such as screws and rivets, and use the above method to connect the pipes. , the installation steps are more complicated, and the stress at the joint is mainly concentrated on the fasteners, and the stress points of the fasteners are susceptible to shear force and fracture failure

Embodiment 1

[0028] Figure 1 to Figure 5 Shows the first embodiment of the pipe fastening connection fittings of the present invention, the connection fittings include an expansion joint 1 and a top wire 2 for expanding the expansion joint 1, the expansion joint 1 includes a connection bottom plate 11, and the connection The lower end of the bottom plate 11 is bent with a jacking plate 12, two side plates 14 are bent on both sides of the connecting bottom plate 11, and the upper ends of the two side plates 14 are provided with a top plate 13 bent to connect to the top of the bottom plate 11. One end of the top wire 2 is connected to The jacking plate 12 is threaded, and the other end is connected to the two top plates 13. When the jacking screw 2 is tightened, the jacking plate 12 expands downward, the top plate 13 expands upward, and drives the two side plates 14 to expand to both sides. Open and the inner wall of the pipe 3 form a four-sided expansion tight connection, which has a simpl...

Embodiment 2

[0032] Figure 6 to Figure 10 Shows the second embodiment of the pipe fastening connection fittings of the present invention, the connection fittings are basically the same as the first embodiment, the only difference is: two top plates 13 overlap each other; When one top plate 13 expands the top plate 13 upwards, the other top plate 13 located at the upper end will also expand upwards through force transmission, and drive the two side plates 14 to expand to both sides and form a four-sided expansion on the inner wall of the pipe 3. connect.

Abstract

The invention discloses a tubular product fastening connection accessory. The tubular product fastening connection accessory comprises an expansion connector and an ejection wire used for expansion of the expansion connector. The expansion connector comprises a connecting base plate. An ejection plate is arranged at the lower end of the connecting base plate in a bent mode, two side plates are arranged on two sides of the connecting base plate in a bent mode, the upper ends of the two side plates are respectively provided with a top plate, the top plates are bent to the upper portions of the connecting base plate, one end of the ejection wire is in threaded concoction the ejection plate, and the other end of the ejection wire is connected with the two top plates. When the ejection wire is screwed, the ejection plate expands downwards, and the top plates expand upwards and drive the two side plates to expand towards two sides and to be connected with the inner wall of a tubular product in a four-face expansion mode. The tubular product fastening connection accessory has the advantages of being simple in structure, convenient to install and capable of protecting a fastener against damage effectively.

Description

technical field [0001] The invention relates to an assembly technology for pipe connection, in particular to a pipe fastening connection fitting. Background technique [0002] In the prior art, there are many structures for connecting pipes through connecting fittings. The more common one is to insert the pipes into the connecting fittings, and then directly connect and fix the pipes and connecting fittings with fasteners such as screws and rivets, and use the above method to connect the pipes. , the installation steps are more complicated, and the stress at the connection is mainly concentrated on the fasteners, and the stress points of the fasteners are prone to shear force and fracture failure. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, and provide a pipe fastening connection fitting which is simple in structure, easy to install, and can effectively protect the fastener...
