Abstract

The utility model relates to a wire fastening device which is composed of a shell body and a ratchet shaft, wherein the shell body forms a U shape, the upper end of the shell body is provided with a wire locking hook, the lower end of the shell body is provided with a wire inlet, and both sides of the middle of the shell body are symmetrically provided with ratchet tooth holes; the middle of the ratchet shaft is provided with a through hole; furthermore, the ratchet shaft is fixed on the ratchet tooth holes arranged on the shell body through ratchet teeth arranged on both ends of the ratchet shaft and thus the ratchet shaft and the shell body are joined into a whole. The utility model has the advantages of simple structure, convenient operation, time saving, labour saving, high work efficiency, etc. Erecting stay wire of the class of wires of building fence facilities can be fleetly strained and fixed by the utility model.

Description

Tightener

The utility model relates to a kind of tightener, particularly relates to a kind of fence facility center line class of building and set up the tightener that backguy is used aspect stringing.

In the prior art; be used to build fence facility center line class and set up backguy aspect stringing; adopt the traditional approach of artificial colligation, elastic threads mostly; not only labor intensity is big; time-consuming; effort; and, because manual operations occurs by stringing not enough because of artificial tension degree through regular meeting; cause building line class loosening; the ejection phenomenon takes place, and influences the construction quality requirement, and building working life and human body come to harm; when building fence facility center line class is erected at stringing aspect quality requirement when higher, the more difficult standard-required that satisfies technology just.

It is a kind of simple in structure, easy to use that the purpose of this utility model is to provide, and can rapidly building fence facility center line class be set up backguy tension, fixing a kind of tightener.

The technical solution of the utility model is: a kind of tightener, it comprises housing, ratchet shaft two-part composition, wherein, housing is a U type shape, and the upper end is provided with locking wire and colludes, the lower end is provided with incoming line, the neutral position bi-side are provided with symmetrical ratchet perforation, and the ratchet shaft neutral position is provided with through hole, and, ratchet shaft is fixed by the ratchet perforation that its two ends are provided with on hook tooth and the housing, and ratchet shaft and housing are joined together.

The utility model has the advantages that: simple in structure, easy to operate, can rapidly building fence facility center line class be set up backguy tension, fixing a kind of tightener.

Fig. 1 is a structural front view of the present utility model;

Fig. 2 is a structure right elevation of the present utility model;

Fig. 3 is a ratchet shaft structural representation of the present utility model;

Fig. 4 is that the A of ratchet shaft of the present utility model is to view.

Below in conjunction with description of drawings embodiment of the present utility model:

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4: a kind of tightener, it comprises housing 1, ratchet shaft 2 two-part composition, wherein, housing 1 is U type shape, and the upper end is provided with locking wire and colludes 3, the lower end is provided with incoming line 4, the neutral position bi-side are provided with symmetrical ratchet perforation 5,6, and the ratchet shaft neutral position is provided with through hole 7, and, ratchet shaft 2 is fixing by the ratchet perforation 5,6 that its two ends are provided with on

hook tooth

8,9 and the housing 1, and ratchet shaft 2 and housing 1 are joined together.One end of hook tooth 8 is provided with the handle 10 that is square shape.

Working principle of the present utility model is: the locking wire that housing 1 upper end is provided with colludes 3 and is fixed on the stationary object, the through hole 7 that incoming line 4 that the line class material of need tensions is provided with by housing 1 lower end and ratchet shaft 2 neutral position are provided with is fixed on the ratchet shaft 2, be rotated counterclockwise the handle 10 of hook tooth 8 ends on the ratchet shaft 1 with spanner, line class material is tightened up, thereby finish the purpose of stringing, and housing 1 adopts metallic material to make, and can bear the pulling force in the stringing process.
