Description

A kind of antisitic defect hose clamp with function of self-tightening

Technical field

The utility model is related to a kind of hose clamp, especially a kind of antisitic defect hose clamp with function of self-tightening.

Background technology

Hose clamp is the fastener of hose-rigid pipe junction, it solves hose clamp in the prior art and is connected for minor diameter hose-rigid pipe When will appear dead angle, lead to the problem of liquids and gases leakage.Traditional hose clamp is made of hoop shell, band and adjusting worm screw, The one end of band is fixedly mounted with hoop shell, and the other end of band is plugged in below the band in hoop shell, and adjusting is equipped on hoop shell Worm screw, by the adjusting for adjusting mobile realization hose clamp tightening range of the worm screw on band adjustment hole.But in actual application In, pipe vibration caused by aging or nature, human factor due to pipeline etc. can all cause the hose clamp installed on pipeline It loosens, leakage problem caused by just will appear due to pipeline connects loosely influences normal work and the life of people.Separately Outside, the stamping hole of punching can cause the pipeline connected different degrees of scuffing or damage on band, will if it is hose Since the fastening dynamics of hose clamp is too big so that hose wall compression compels to be got into the stamping hole of band, to influence later stage larynx The dismounting of hoop.

Invention content

The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of with design is scientific and reasonable, fastening The hose clamp that power is strong, avoids damage to pipeline, is simple in structure, being easily achieved, can automatically adjust fastening amount with the variation of external environment.

The utility model solves its technical problem and following technical scheme is taken to realize：

A kind of antisitic defect hose clamp with function of self-tightening, including hoop shell, band and adjusting worm screw, are fixedly mounted in the end of band There is hoop shell, bind round and adjusting worm screw is installed inside shell, it is characterised in that：Further include self-tightening mechanism and antisitic defect mechanism, it is described from Tight mechanism is made of catch and spring leaf, and mounting jaw is respectively symmetrically formed at the both ends of catch, is formed in the middle part of catch solid Determine pawl, catch is installed with by mounting jaw on the inner wall of the band, fixed jaw is provided between band and catch Fixed spring leaf；The antisitic defect mechanism is made of sheath and metal connection side, and the sheath, which is installed on, is formed with stamping On the band of hole side, metal connection side is provided at the upper port of the sheath, which connects side and band fixing end It mutually welds end.

Moreover, the spring leaf is spring steel spring leaf or stainless steel spring leaf.

Moreover, the sheath is protective metal shell or vulcanie sheath.

The advantages of the utility model and good effect are：

1. the antisitic defect hose clamp with function of self-tightening, by increasing the design of spring leaf on the basis of traditional hose clamp, In this way, when hose clamp loosens, spring leaf deforms upon, and is combined with the amount that catch compensates hose clamp loosening together, ensure that pipeline connects The place of connecing is fastenedly connected, and avoids the leakage problem of object in pipeline；By in pipeline and the position that stamping hole is in contact on band Install sheath, effectively prevent spending greatly because of fastening force, and caused by tube wall deformation even the problem of being got into stamping hole, very Good protects pipeline from damage.

2. the antisitic defect hose clamp with function of self-tightening, by the way that spring leaf to be designed as being made of spring steel or stainless steel Spring leaf, improve the hardness and toughness of spring leaf, make spring leaf application when elasticity more preferably, fastening effect is more preferable.

3. the utility model scientific structure design is reasonable, have that fastening force is strong, avoids damage to pipeline, is simple in structure, being easy to The advantages of realizing, capable of automatically adjusting fastening amount with the variation of external environment, is a kind of hose clamp with higher innovation.

Specific implementation mode

Below in conjunction with the accompanying drawings, by specific embodiment, the utility model is described in further detail.Following embodiment is only retouched The property stated, it is not restrictive, protection scope of this utility model cannot be limited by this.

A kind of antisitic defect hose clamp with function of self-tightening, including hoop shell 2, band 6 and adjusting worm screw 1, in the end of band It is fixed with hoop shell, binds round and adjusting worm screw is installed inside shell, innovation is：Further include self-tightening mechanism and antisitic defect mechanism, The self-tightening mechanism is made of catch and spring leaf 7, mounting jaw 9 is respectively symmetrically formed at the both ends of catch, in catch Middle part is formed with fixed jaw 8, and catch is installed with by mounting jaw on the inner wall of the band, is provided between band and catch Pass through the fixed spring leaf of fixed jaw；The antisitic defect mechanism is made of sheath 5 and metal connection side 4, and the sheath is worn On the band for being formed with stamping hole side, be provided at the upper port of the sheath metal connection side, the metal connect side with It mutually welds the end of band fixing end 3.

The spring leaf is spring steel spring leaf or stainless steel spring leaf.

The sheath is protective metal shell or vulcanie sheath.

By increasing the design of spring leaf on the basis of traditional hose clamp, in this way, when hose clamp loosens, shape occurs for spring leaf Become, is combined with the amount that catch compensates hose clamp loosening together, ensure that being fastenedly connected for pipeline junction, avoid object in pipeline Leakage problem；By the way that sheath is arranged with the position that stamping hole is in contact on band in pipeline, effectively prevent because of fastening dynamics It is excessive, and caused by tube wall deformation even the problem of being got into stamping hole, protect pipeline from damage well.

Although disclosing the embodiments of the present invention and attached drawing for the purpose of illustration, those skilled in the art can be with Understand：It is not departing from the utility model and spirit and scope of the appended claims, various substitutions, changes and modifications are all can Can, therefore, the scope of the utility model is not limited to embodiment and attached drawing disclosure of that.
