Clamp ring structure

Abstract

The invention relates to a clamp ring structure which is characterized by comprising a fastening bolt, a fastening plate and an unclosed circular hoop. The fastening plate is connected with the fastening bolt by screw threads; a gasket is further connected onto the fastening bolt, and the fastening plate is positioned between the gasket and the head of the fastening bolt; the circular hoop is enclosed by an elastic steel wire; a first connecting end and a second connecting end of the circular hoop cross each other and then are respectively connected with the fastening plate and the gasket; the first connecting end and the second connecting end are two free ends of the elastic steel wire, or the first connecting end is a combination of the two free ends of the elastic steel wire. The clamp ring structure has the advantages that the two connecting ends of the circular hoop are respectively connected to the fastening plate and the gasket in a crossing manner, the fastening plate on the fastening bolt can rotate, accordingly, the distance from the fastening plate to the gasket can be prolonged, the diameter of an unclosed circular ring enclosed by the circular hoop can be diminished, and effects of tightly tying hoses on steel pipes can be realized.

Description

technical field [0001] The invention relates to a snap ring structure. Background technique [0002] In the underground construction process of coal mines, it is more common to softly connect the hose to the steel pipe by tying. Especially in the drainage systems such as drilling stubble, upper corner pipe connection on the mining surface, etc., it is essential to use. In the prior art, to connect the hose to the steel pipe, one end of the hose is usually sleeved on the port at one end of the steel pipe. This connection mode is the soft connection mentioned above. Usually, in order to ensure the effect of the soft connection, iron wires are used to tie the hose to fix the hose sleeved outside the steel pipe to ensure that it will not slip. But, existing this mode that adopts iron wire to tie a knot, because iron wire two ends are free ends, it is not easy to fix, and it is easy to loosen when tied. When the air pressure in the steel pipe is high, this kind of knotting me...

AI Technical Summary

Problems solved by technology

However, in the existing method of tying the knot with iron wire, since both ends of the iron wire are free ends, it is not easy to fix, and it is easy to loosen when tying the knot.

When the air pressure inside the steel pipe is high, this way of tying is prone to leakage, leaking, and hole pulling accidents, which will lead to gas alarms

In severe cases, it may even affect the safety of passing personnel

Moreover, when iron wire is used for tying, the tying process is time-consuming and laborious

When it is temporarily tied, the iron wire cannot be reused after being tied once, and the loss is large

When the binding time is long, the iron wire is easy to rust or even break, which will also lead to many unsafe effects including the above

Therefore, the effect of adopting iron wire binding in the prior art is very unsatisfactory
