Description
Technical field
The utility model relates to a kind of convenient regulating type thread take-up spring seat.
Background technology
The line that supplies of sewing machine is to wait until that according to the elasticity of fabric character reaches the requirement to stitching, by regulating the angle of thread take-up spring, regulates the elastic force of thread take-up spring, thereby reaches the purpose of regulating thread tension.And commonly used be fixed thread take-up spring seat, when regulating the elastic force of thread take-up spring, all need unclamp the angle that hold-down screw mixes up thread take-up spring, again trip bolt is screwed, both time-consuming, be not easy the requirement that reaches required again.
The utility model content
The purpose of this utility model provides a kind of convenient regulating type thread take-up spring seat, and is simple in structure, easy to operate, quick, to overcome present prior art above shortcomings.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of convenient regulating type thread take-up spring seat, comprise thread take-up spring seat and pin arm, the thread take-up spring seat is by the screwed hole place of hold-down screw locking pin arm, between one end of thread take-up spring seat and the pin arm against thread take-up spring, be provided with jump ring between the other end of thread take-up spring seat and the hold-down screw, another screwed hole place of pin arm is by another hold-down screw stay hook spring.
The beneficial effects of the utility model are: simple in structure, easy to operate, quick, in adjustment process,, saved working time widely without any need for instrument.
Description of drawings
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the structural representation of the described a kind of convenient regulating type thread take-up spring seat of the utility model embodiment.
Among the figure:
1, thread take-up spring seat; 2, pin arm; 3, hold-down screw; 4, thread take-up spring; 5, jump ring; 6, hold-down screw; 7, hook spring.
The specific embodiment
As shown in Figure 1, the described a kind of convenient regulating type thread take-up spring seat of the utility model embodiment, comprise thread take-up spring seat 1 and pin arm 2, thread take-up spring seat 1 is by the screwed hole place of hold-down screw 3 locking pin arms 2, between one end of thread take-up spring seat 1 and the pin arm 2 against thread take-up spring 4, be provided with jump ring 5 between the other end of thread take-up spring seat 1 and the hold-down screw 3, another screwed hole place of pin arm 1 is by another hold-down screw 6 stay hook springs 7.
During use, jump ring 5, thread take-up spring seat 1, thread take-up spring 4 is enclosed within on the hold-down screw 3 in regular turn, and 5 one of jump rings are stuck on the hold-down screw 3, the other end is stuck on the annular knurl groove of thread take-up spring seat 1 outer rim, thread take-up spring 4 its tail ends are inserted in the aperture on the thread take-up spring seat 1, and an end of hold-down screw 3 is fastened on the pin arm 2, if need to regulate the elastic force of thread take-up spring 4, with the moving thread take-up spring seat 1 of hand-screw, one end of jump ring 5 slides on the annular knurl groove of thread take-up spring seat 1 outer rim, when desired location was loosed one's grip, jump ring 5 promptly was stuck in the annular knurl groove of thread take-up spring seat 1 outer rim, and thread take-up spring seat 1 can not be rotated, again since thread take-up spring 4 its tail ends be inserted in the aperture on the thread take-up spring seat 1, and the other end is hooked by hook spring 7, thus thread take-up spring 4 be tensioned or loosen, thereby reached the purpose of regulating thread take-up spring 4 easily.
