It is connect with the first side plate, the limit film is V-shaped, and the surface of the regulating wheel is equipped with several limiting slots with limit film cooperation；
The top of the connecting plate is equipped with the transition face of arc, and the sewing thread on tension disk is drawn by transition face.The utility model work
Make principle: when need to adjust tension disk it is elastic when, rotating wheel, runner drive clamp axis rotation, due to regulating wheel and clamp axis
It being threadedly coupled, the rotation of clamp axis can drive regulating wheel to move along clamp axis, when regulating wheel is mobile to runner direction, clamp spring
It is compacted, to adjust the elastic of tension disk；Limit film of the utility model due to increasing V-arrangement, the limit of limit film and regulating wheel
Position slot cooperation, can prevent regulating wheel from clamp axis being followed to rotate, but regulating wheel can be translated；In addition, the line in tension disk
It needs to draw, lead is needed than sharp at the top of the top of connecting plate, existing connecting plate, and lead is easy during pullling
It is cut off, the utility model increases the transition face of arc, and lead is effectively prevent to be cut off.
As an improvement, the connection sheet is connect by bolt with the first side plate.
As an improvement, the transition face is formed by the U-board covered on connecting plate, or the circle by being located at the top of connecting plate
The outside wall surface of mast is formed.
Brought beneficial effect is the utility model compared with prior art:
The limiting slot of limit film of the utility model due to increasing V-arrangement, limit film and regulating wheel cooperates, and can prevent regulating wheel
Clamp axis is followed to rotate, but regulating wheel can be translated；In addition, the line in tension disk needs to draw, lead need across
The top of connecting plate, existing connecting plate top is than sharp, and lead is easy to be cut off during pullling, and the utility model increases
The transition face of arc, effectively prevent the lead to be cut off.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings of the specification.
As shown in Figure 1, a kind of sewing machine thread clamping mechanism, the mounting base 2 including tension disk 1 and for installing tension disk 1.Institute
It states tension disk 1 and includes regulating wheel 14, runner 11, clamp axis 15, clamp spring 13 and two panels intermediate plate 12, the runner 11 and clamp
Axis 15 connects, and the clamp axis 15 is equipped with thread segment, and regulating wheel 14 is threadedly coupled with clamp axis 15；Lead 3 passes through two intermediate plates
It is drawn after 12, clamp spring 13 is located between regulating wheel 14 and intermediate plate 12, by 14 compression clip wire spring 13 of regulating wheel, to change
Become the chucking power of intermediate plate 12.
As shown in Figure 1, the mounting base 2 includes the first side plate 21, the second side plate 22 and connecting plate 23, the first side plate 21
Side is connect by connecting plate 23 with the side of the second side plate 22, and first side plate 21 is equipped with U-lag, second side plate
