Abstract

The utility model relates to an elastic flexible pipe clamp which is a mutually nested hoop. A connecting buckle and a self-locking buckle are respectively arranged on the mutual nesting position of an inner rim ring and an outer rim ring of the hoop. Two compensation rings are arranged on the outer rim ring of the hoop, and a guide groove is radially arranged on the central section between the two compensation rings. A head restraint is inserted in the guide groove, and the head restraint is fixed with the inner rim ring of the hoop. At least one compensation ring is made on the hoop, and a guide groove and a head restraint are arranged between the compensation rings, thereby overcoming the defects of the flexible pipe which expends with heat and contracts with cold. The guide groove and the head restraint ensure solid buckling.

Description

A kind of elastic hose clip

Technical field

The utility model belongs to mechanical field, relates to pipeline connecting parts clip, especially a kind of elastic hose clip.

Background technique

When carrying out being connected and fixed of flexible pipe, conventionally adopt elastic hose clip.Current flexible collar, is only to buckle and change at self-locking buckle and Connection Card, and not only clamping becomes loaded down with trivial details, the compensation of the rising-heat contracting-cold between flexible pipe is not changed simultaneously, causes the functional effect of this flexible collar poor.

In addition, the connection part sealing at clip between flexible pipe is poor, and existing clip is difficult to guarantee the sealing between interface.

Model utility content

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of elastic hose clip that can simultaneously guarantee compensation effect and sealing effect is provided.

The purpose of this utility model is achieved through the following technical solutions:

A kind of elastic hose clip, it is a mutually nested garter spring, at garter spring outer rim ring and the mutually nested position of inner ring, be shaped with respectively and be connected buckle and self-locking buckle, it is characterized in that: the outer rim ring at garter spring is shaped with two compensated loops, between two compensated loops, middle part is radially shaped with a guide groove, on this guide groove, be embedded with a dop, the inner ring of this dop and garter spring fixes.

And the inner ring of described garter spring is for relatively nested, its nested mode is on inner ring, to be shaped with a direction recess, on another inner ring in opposite directions of garter spring, is shaped with an inside guiding convex tendon, and this guiding convex tendon and direction recess mutually lead and coordinate interlocking.

Advantage of the present utility model and good effect are:

1, this clip is shaped with at least one compensated loop on garter spring, only has guide groove and dop between compensated loop, can compensate thus the problem of expanding with heat and contract with cold producing between flexible pipe, and guide groove and dop have guaranteed that overlap joint firmly.

2, this clip is shaped with respectively a guiding convex tendon and a direction recess at the garter spring handing-over position of inner edge, and this guiding convex tendon and direction recess mutually lead and coordinate interlocking, have not only avoided the distortion of garter spring, have also improved garter spring internal diameter to clamped pipeline 360 simultaneously ⁰sealability.

Accompanying drawing explanation

Fig. 1 is structural front view of the present utility model (locking state);

Fig. 2 is the right elevation of Fig. 1;

Fig. 3 is the sectional perspective structural representation of Fig. 2;

Fig. 4 is the garter spring releasing orientation schematic diagram of Fig. 1.

Embodiment

Below in conjunction with accompanying drawing, embodiment of the present utility model is further described; The present embodiment is descriptive, is not determinate, can not limit thus protection domain of the present utility model.

An elastic hose clip, is a mutually nested garter spring 3, at garter spring outer rim ring and the mutually nested position of inner ring, is shaped with respectively and is connected buckle 1 and self-locking buckle 2.

Innovative point of the present utility model is:

1, the outer rim ring at garter spring is shaped with two compensated loops 4, and the present embodiment accompanying drawing is to take two compensated loops as example is described, and can be also a plurality of; Between two compensated loops, middle part is radially shaped with a guide groove 8, is embedded with a dop 5 on this guide groove, and the inner ring of this dop and garter spring fixes, and plays thus the leading role between inner ring and outer rim ring.

2, at the inner ring of garter spring for relatively nested, its nested mode is on inner ring, to be shaped with a direction recess 7, on another inner ring in opposite directions of garter spring, be shaped with an inside guiding convex tendon 6, this guiding convex tendon and direction recess mutually lead and coordinate interlocking, realize thus the guiding locking between the inner ring of garter spring, avoid the loosening and distortion of clip, also improved the sealability of garter spring internal diameter to clamped pipeline simultaneously.

Claims

1. an elastic hose clip, it is a mutually nested garter spring, at garter spring outer rim ring and the mutually nested position of inner ring, be shaped with respectively and be connected buckle and self-locking buckle, it is characterized in that: the outer rim ring at garter spring is shaped with two compensated loops, between two compensated loops, middle part is radially shaped with a guide groove, on this guide groove, be embedded with a dop, the inner ring of this dop and garter spring fixes.

2. elastic hose clip according to claim 1, it is characterized in that: the inner ring of described garter spring is for relatively nested, its nested mode is on inner ring, to be shaped with a direction recess, on another inner ring in opposite directions of garter spring, be shaped with an inside guiding convex tendon, this guiding convex tendon and direction recess mutually lead and coordinate interlocking.
