Abstract

The utility model relates to a self-locking type hose clamping hoop, which is composed of a clamping belt 2, a clamping plate body 4, springs 5, and a clamping tongue 6, wherein, the middle part of the left side of the clamping belt is provided with a set of clamping teeth 1; the middle part of the right side of the clamping belt is provided with a set of positioning groove holes 3; the right end of the clamping belt is connected with the left end of the clamping plate body 4 through a pin axle; the upper part of the clamping plate body 4 is provided with the springs 5; the right end of the clamping plate body 4 is connected with the clamping tongue 6 through the pin axle. The transversal profile of the clamping plate body 4 forms a circular arc shape, and the upper and the lower sides of the clamping plate body are provided with folding edges; the clamping tongue 6 also forms a circular arc shape, and the circular arc of the clamping tongue is concentric with that of the clamping plate body. The utility model has the advantages of beautiful appearance of configuration, novelty, liberality, tight and fixing self-locking, time saving, labour saving, and convenient assembly and disassembly.

Description

The self-locking hose clamp

The utility model belongs to flexible pipe and connects fastening piece, a kind of self-locking hose clamp.

In the life, the field of using flexible pipe to peg graft to connect is very wide, for the flexible pipe after preventing to connect comes off at work, often uses clip fastening.Existing clip mainly contains two kinds of monomer-type and opposite openeds, all is the hole bolt tightenings by the clip end when fastening.In the less place of hose locational space, often difficult when tightening up.And the specification of clip must with the supporting use of flexible pipe specification, do not have interchangeability, pattern is outmoded, and is attractive in appearance inadequately.

The purpose of this utility model is in order to overcome the deficiency that traditional clip exists, therefore to have designed a kind of self-locking hose clamp elegant in appearance, easy for installation, that pattern is novel.

The utility model is realized as follows:

The self-locking hose clamp, mainly formed by cassette tape 2, clamp body 4, spring 5 and block tongue 6, left middle part at cassette tape 2 is provided with one group of latch 1, its right-hand middle part is provided with one group of location notch hole 3, the right-hand member of cassette tape 2 links by the left end of bearing pin and clamp body 4, on the top of clamp body 4 spring 5 is housed, is connected with block tongue 6 by bearing pin at the right-hand member of clamp body 4.The transverse section of clamp body 4 is circular-arc, has flanging on it.It is circular-arc that block tongue 6 also is, and with clamp body 4 be isocentric circular arc.

The utility model has the advantages that: handsome in appearance, novelty is generous, self-locking is fastening, time saving and energy saving, easy accessibility, need not can reach fastening purpose by any instrument.

Fig. 1 is that expansion master of the present utility model looks schematic representation;

Fig. 2 is an expansion schematic top plan view of the present utility model;

Fig. 3 is a use schematic representation of the present utility model;

Fig. 4 is a working state schematic representation of the present utility model.

Introduce embodiment of the present utility model with reference to the accompanying drawings:

The self-locking hose clamp, adopt sheetmetal that cassette tape 2 is tailored moulding during enforcement, correspondingly on cassette tape 2 then stamp out latch 1 and location notch hole 3, in the middle of the right part of cassette tape 2, roll out pin shaft hole, clamp body 4 also is to adopt the thin metal blank impact briquetting, on it, the bottom stamps out flanging, a left side, right two ends roll out axis hole, in clamp body 4 tops, load onto spring 5, block tongue 6 also is to adopt the metal sheet impact briquetting, its left end middle part rolls out axis hole, respectively cassette tape 1 and block tongue 6 is connected on the cassette tape 2 with two bearing pins, has promptly formed complete hose clamp.During use, cassette tape 2 is looped around on the fastening position of flexible pipe, block tongue 6 is embedded in a certain latch 1, depressing clamp body 4 gets final product, as feel that tautness is not enough, then liftable clamp body 4 is depressed the tautness that 4 of clamp bodies can reach to be needed after making block tongue 6 embed in the corresponding latch 1 more again, the effect of spring 5 is block tongue 6 to be close on the cassette tape 2 can not lift voluntarily, guarantees its self-locking property.
