Abstract
Sewing machine field is the utility model is related to, refers in particular to a kind of take-up linkage, including mobile jib, roller, pin, the pin is fixed on mobile jib end, the roller is set in outside pin, and roller inner peripheral surface and pin outer peripheral surface all offer the groove of ring-type, and ball is provided with the groove；The pin passes through mobile jib end, and the end of pin is connected with nut；Back-up ring is provided between the roller and mobile jib；Plain washer is provided between the nut and mobile jib.After such scheme, component service life can be effectively improved, reduces noise.
Description
Technical field
Sewing machine field is the utility model is related to, refers in particular to a kind of take-up linkage.
Background technology
At work, suture passes through the pin hole of suture needle to sewing machine, drives suture to pass repeatedly through by the reciprocating motion of suture needle
Clothing realizes the suture of clothing, and realizes this motion, is to drive the roller part in take-up bar assembly to exist by cam rotation
Slided in the groove of cam, to drive needlework to move up and down.In traditional design, roller is arranged on mobile jib by pin,
It is sliding friction between roller and pin, therefore there is larger noise, and service life is also shorter, therefore, the present inventor couple
This makes further research, and develops a kind of take-up linkage, thus this case produces.
Utility model content
The purpose of this utility model is to provide a kind of take-up linkage, can effectively improve component service life, reduce
Noise.
To achieve these goals, the technical solution of the utility model is as follows：
A kind of take-up linkage, including mobile jib, roller, pin, the pin are fixed on mobile jib end, and the roller is arranged
Outside pin, roller inner peripheral surface and pin outer peripheral surface all offer the groove of ring-type, and ball is provided with the groove；Institute
State pin and pass through mobile jib end, the end of pin is connected with nut；Back-up ring is provided between the roller and mobile jib；The nut
Plain washer is provided between mobile jib.
Further, the groove is set up in parallel for twice.
After such scheme, the utility model compared with prior art, has advantages below：
Friction between roller and pin is changed to rolling friction by sliding friction, can effectively reduce roller and pin it
Between resistance, reduce noise.
Brief description of the drawings
Fig. 1 is explosive view of the present utility model；
Label declaration
Mobile jib 1, roller 2, pin 3, groove 4, nut 5, back-up ring 6, plain washer 7.
Embodiment
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings.
As illustrated, a kind of take-up linkage that the utility model discloses, including mobile jib 1, roller 2, pin 3, the post
Pin 3 passes through in the end of mobile jib 1, and the roller 2 is set in the one end of pin 3, and the other end and the nut 5 of pin 3 fasten, rolling
The inner peripheral surface of post 2 and the outer peripheral surface of pin 3 all offer twice annular recess 4 arranged side by side, and ball is provided with the groove 4,
Make between roller 2 and pin 3 for rolling friction, so as to effectively reduce noise during thread take-up tension lever motion, improve thread take-up tension lever
Service life.
Back-up ring 6 is provided between roller 2 and mobile jib 1, plain washer 7, back-up ring 6 and plain cushion are provided between nut 5 and mobile jib 1
Circle 7 is used for the friction for protecting mobile jib 1 not by nut 5 and roller 2, and can expand the lifting surface area of mobile jib 1, shares the institute of mobile jib 1
The pressure born.
Specific embodiment of the utility model is above are only, but design concept of the present utility model is not limited thereto, it is all
The change of unsubstantiality is carried out to the utility model using this design, the row for invading scope of protection of the utility model all should be belonged to
For.
Claims (2)
- A kind of 1. take-up linkage, it is characterised in that：Including mobile jib, roller, pin, the pin is fixed on mobile jib end, institute State roller to be set in outside pin, roller inner peripheral surface and pin outer peripheral surface all offer the groove of ring-type, set in the groove It is equipped with ball；The pin passes through mobile jib end, and the end of pin is connected with nut；Gear is provided between the roller and mobile jib Circle；Plain washer is provided between the nut and mobile jib.
- A kind of 2. take-up linkage according to claim 1, it is characterised in that：The groove is set up in parallel for twice.
