Description

Tensioner

Technical field

The utility model relates to a kind of tensioner.

Background technology

Traditional tensioner owing to contact the warning position, is subjected to the influence of yarn waxing in use, service time is long more, and contact lever is waxed thick more, thereby it is bad to cause reporting to the police, this kind type of alarm makes scrapping than higher of fabric, and installation and inconvenient debugging, and firmness is poor.

The utility model content

The purpose of this utility model is to provide a kind of tensioner, and it is highly sensitive to have a break alarm, thereby has reduced the scrappage of fabric, installs and debugging is convenient and firm characteristics.

In order to achieve the above object, the technical solution of the utility model is:

A kind of tensioner comprises tension cap, tension force fixed block, yarn take-up spring axle, great circle porcelain bead, thread take-up spring regulator, take-up torsion spring, yarn take-up spring cover plate, back-up block, roundlet porcelain bead, take-up spring abutment, yarn take-up spring, contact lever; Offer 12 even holes on the tension force capping, offer 2 perforation on the tension cap both sides, 12 even in the holes respectively fit 12 great circle porcelain beads are installed; The front end of 12 line ball springs is crimped with 12 take-up spring abutments, and end is provided with 12 spring eyes, in 12 spring eyes respectively fit 12 roundlet porcelain beads are installed; Take-up spring abutment, yarn take-up spring cover plate, take-up torsion spring, thread take-up spring regulator fit one by one are installed on the yarn take-up spring axle that is cut with long spring trough, by first back-up ring each parts are fixed on the yarn take-up spring axle; After fit is equipped with round stage clip respectively with the two ends of yarn take-up spring axle, the yarn take-up spring axle sleeve is closed be installed in 2 perforation of offering on the tension cap both sides again, on the two ends of yarn take-up spring axle, be inserted in the tension force fixed block then, and fix in that tension cap is inboard with second back-up ring; The contact lever two ends are separately installed with back-up block.

Described back-up block is fixed on the tension cap upper end by screw and nut respectively, and is installed with the annular knurl holding screw on the back-up block.

After the utility model adopts technique scheme, its beneficial effect is: after using tensioner device of the present utility model, the take-up spring abutment head contact of break alarm remolding sensitivity island essence is reported to the police and is greatly improved, thereby reduced the scrappage of fabric, installed and debug than convenient and firm in the past.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

As shown in Figure 1, a kind of tensioner comprises tension cap 1, tension force fixed block 2, yarn take-up spring axle 3, great circle porcelain bead 4, thread take-up spring regulator 8, take-up torsion spring 9, yarn take-up spring cover plate 10, back-up block 11, roundlet porcelain bead 13, take-up spring abutment 14, yarn take-up spring 15, contact lever 16; Offer 12 even holes 17 on 1 of the tension cap, offer on tension cap 1 both sides 18,18 ', 12 of 2 perforation even in the holes 17 respectively fit 12 great circle porcelain beads, 4 blended rubber water be installed be adhesively fixed; The front end of 12 line ball springs 15 is crimped with 12 take-up spring abutments 14, and end is provided with in 19,12 spring eyes 19 of 12 spring eyes respectively that fit is equipped with 12 roundlet porcelain beads 13 and fixing; Take-up spring abutment 14, black yarn take-up spring cover plate 10, circle take-up torsion spring 9, black plastic thread take-up spring regulator 8 fit one by one is installed on the yarn take-up spring axle 3 that is cut with long spring trough 20, by first back-up ring 5 each parts is fixed on the yarn take-up spring axle 3; With the two ends of putting on the yarn take-up spring axle 3 behind the above-mentioned parts respectively fit round stage clip 6 is installed, after 6 ', again yarn take-up spring axle 3 fits are installed in 2 perforation 18 of offering on tension cap 1 both sides, on 18 ', on the two ends of yarn take-up spring axle 3, be inserted in tension force fixed block 2,2 ' then, and with second back-up ring 7,7 ' tension cap 1 inboard the fixing, whole string yarn take-up spring 15 is fixed on above the tension cap, and can rotates flexibly; Elongated cylindrical contact lever 16 two ends are separately installed with back-up block 11,11 '; Back-up block 11,11 ' is fixed on tension cap 1 upper end by screw 19,19 ' and nut 20,20 ', and is installed with annular knurl holding screw 12,12 ' on the back-up block 11,11 ' respectively; Withstand contact lever 16, contact lever 16 can both be fixed at diverse location, play the effect of regulating contact lever 16.
