Abstract

The utility model belongs to the technical field of fasteners, a safe prevention of seepage type in -band lining larynx hoop is related to, including hoop shell, locking worm, steel band, inside lining, including the inside lining curves the annular, the steel band curves the annular and adorn admittedly mutually with annular steel band the inner at outer nested within each other, hoop shell, locking worm suit is in binding round the shell and mesh mutually with annular steel band outer end, the inside lining, tooth, its characterized in that are taken to the system on it: take the tooth to take the tooth for double arcs shape. The utility model discloses safe prevention of seepage type in -band lining larynx hoop, structural design scientific and reasonable, it be the bar with the pipe fitting contact point, has certain elasticity during locking, and it to have better locking force both to have had, can effectively prevent to take the tooth to lead to the fact the damage to the pipe fitting again, and be safe in utilization, and the while has stronger seepage and the function of using repeatedly of preventing again, is a safe prevention of seepage type in -band lining larynx hoop who has higher novelty.

Description

A kind of safe antiseepage type band liner larynx hoop

Technical field

The utility model belongs to fastening connection piece technical field, particularly one safe antiseepage type band liner larynx hoop.

Background technique

Larynx hoop is the most frequently used fastening connection piece connected between various flexible pipe and pipe joint, usually requires that it has good locking function, preferably antiseepage function and good use repeatly function.Along with the development of technology, based on the working environment of connecting tube, pipe fitting material, pipe fitting specification type difference and more concrete, to have more specificity requirement is proposed to link.And larynx hoop in the past, although highly versatile, in particularity, attend to one thing and lose sight of another unavoidably, be difficult to the specific demand meeting some special circumstances.Namely the utility model is a kind of link being applicable to the pipe fitting that tube wall thickness is thinner, material is more soft, under guarantee has the prerequisite of better locking function, and has good barrier performance and good use repeatly performance simultaneously.Had similar products, but its band tooth is triangle, itself and pipe fitting point of contact are linear, and defect very easily damages pipe fitting, cause pipe fitting seal to lose efficacy, bring potential safety hazard in the past; And barrier properties is poor in running, band tooth is yielding, and reusability is also poor.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, under a kind of prerequisite having better locking function is provided, Security is high, does not damage pipe fitting, and has the safe antiseepage type band liner larynx hoop of good use repeatly performance and good barrier performance simultaneously.

The utility model solves its technical problem and is achieved through the following technical solutions:

A kind of safe antiseepage type band liner larynx hoop, comprise hoop shell, locking worm screw, steel band, liner, liner curves annular, and to curve annular at interior, steel band mutually nested outside, hoop shell is fixedly mounted with mutually with ring steel belt the inner, locking worm set is loaded on and binds round in shell and be meshed with ring steel belt outer end, described liner, it is shaped with band tooth, it is characterized in that: described band tooth is two arcuate zone tooth.

And described pair of arcuate zone tooth, its cross section is " M " shape.

Advantage of the present utility model and beneficial effect are:

The utility model safe antiseepage type band liner larynx hoop, scientific structure design is reasonable, itself and pipe fitting point of contact are bar shaped, there is during locking certain elasticity, both had and can have good coupling mechanism force, and can effectively prevent again band tooth from causing damage to pipe fitting, use safety, have again the stronger function preventing seepage and Reusability, be a kind of safe antiseepage type band liner larynx hoop with higher innovation simultaneously.

Fig. 3 is that the AA of Fig. 1 is to sectional view.

Accompanying drawing mark illustrates:

1-binds round shell, and 2-locks worm screw, 3-steel band, 4-liner, the two arcuate zone tooth of 5-.

Embodiment

Below by specific embodiment, the utility model is described in further detail, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.

A kind of safe antiseepage type band liner larynx hoop, comprises hoop shell 1, locking worm screw 2, steel band 3, liner 4.Liner curves annular, and to curve annular at interior, steel band mutually nested outside, and hoop shell is fixedly mounted with mutually with ring steel belt the inner, and it is interior and be meshed with ring steel belt outer end that locking worm set is loaded on hoop shell.Inside be lining with and be shaped with band tooth, band tooth is two arcuate zone teeth 5.Two arcuate zone tooth, its cross section is " M " shape.

Working principle of the present utility model:

When using the utility model as pipe connecting component, when particularly comparatively soft as tube material, that tube wall is thinner pipe fitting connects, two arcuate zone tooth makes this larynx hoop have good coupling mechanism force, its pair of arcuate zone tooth and pipe fitting point of contact are bar shaped simultaneously, and surface of contact uniform force, has certain elasticity, not easy damaged pipe fitting, Security is high, also can prevent seepage preferably in operation, and can Reusability.

Although disclose embodiment of the present utility model and accompanying drawing for the purpose of illustration, but it will be appreciated by those skilled in the art that: in the spirit and scope not departing from the utility model and claims, various replacement, change and amendment are all possible, therefore, scope of the present utility model is not limited to the content disclosed in embodiment and accompanying drawing.

Claims

1. a safe antiseepage type band liner larynx hoop, comprise hoop shell, locking worm screw, steel band, liner, liner curves annular, and to curve annular at interior, steel band mutually nested outside, hoop shell is fixedly mounted with mutually with ring steel belt the inner, locking worm set is loaded on and binds round in shell and be meshed with ring steel belt outer end, described liner, it is shaped with band tooth, it is characterized in that: described band tooth is two arcuate zone tooth.

2. safe antiseepage type band liner larynx hoop according to claim 1, it is characterized in that: described pair of arcuate zone tooth, its cross section is " M " shape.
