Push-pull elastic fixed connector

Abstract

A pushing and expanding drawing type elastic fixed connector comprises a screw head, an expanding sleeve and a tight expanding bolt; and the tight expanding bolt is installed behind an installing channel of the expanding sleeve, the screw head is connected with the connecting end of the tight expanding bolt, and therefore the tight expanding bolt can be kept in the installing channel. By means of the simple pushing and pulling action, the pushing and expanding drawing type elastic fixed connector makes a connecting object and a connected object fast and conveniently connected and separated, so that operation is convenient. The pushing and expanding drawing type elastic fixed connector is simple and compact in structure; no gap exists between connecting pieces; the sliding phenomenon is avoided after installation; the fastening force is high; machining is easy; and the pushing and expanding drawing type elastic fixed connector can be repeatedly used, and therefore the pushing and expanding drawing type elastic fixed connector has better economical performance.

Description

technical field [0001] The present invention relates to a fixed connector, in particular to a push-expandable elastic fixed connector, wherein the push-expandable elastic fixed connector can connect and separate the connected object and the connected object conveniently, and After the object to be connected is separated from the object to be connected, the push-expand-pull elastic fixed connector can be used repeatedly. Background technique [0002] Fixed connectors are widely used in various engineering machinery and engineering construction. There are many mechanical fixed connection methods in the prior art. According to their detachability, they are divided into detachable connections and non-detachable connections. Detachable connections include bolts Connection, key connection, pin connection, etc. Non-detachable connection includes rivet connection, welding, glue connection, etc. The advantages and disadvantages of these connection methods are also different, and ther...

AI Technical Summary

Problems solved by technology

However, the expansion sleeve cannot recover by itself after being squeezed and deformed by the screw rod. Because the sleeve cannot be taken out, the expansion bolt cannot be taken out directly.

Therefore, it is difficult to pull out the ordinary expansion bolt after installation, and it is easy to damage the wall, and the expansion bolt is severely deformed and cannot be reused.
