Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

As shown in Figures 1 and 2, which includes bracket 10, the main shaft 20 on the bracket 10, is connected at The driven wheel 30 of 20 one end of main shaft, set on 20 other end of main shaft and be fixedly connected with its top with main shaft 20 connecting rod 40, The connector sleeve 50 that is rotatably connected with the bottom end of the connecting rod 40, the unilateral bearing 60 on the connector sleeve 50 and it is supported in the list The top of idler wheel 70 on bearing 60, the connecting rod 40 is connect with 20 bias of main shaft.

The driven wheel 30 is connect by driving members such as belt or chains with the driving wheel on sewing machine.In use, this is actively Wheel rotation drives driven wheel 30 to rotate, and drives main shaft 20 to rotate by driven wheel 30, to make the top of connecting rod 40 around main shaft 20 Rotation, and then make the bottom end of connecting rod 40 that 50 swing of connector sleeve be driven to make 50 band of connector sleeve due to the setting of unilateral bearing 60 Dynamic idler wheel 70 discontinuously rotates in one direction always, and the direction is the side for promoting the cloth of sewing machine to be formed to rear side dilatory force To.Setting by the mop wheel apparatus is to the tractive force of cloth application backward is processed on sewing machine, from what is manually pulled Arduously.

The idler wheel 70 is silica gel wheel, and outer surface forms rough surface.When it is implemented, can be also equipped with outside the idler wheel 70 multiple Outwardly projecting anti-skidding salient point prevents from skidding to enhance frictional force when idler wheel 70 is outer and cloth contacts.

In the present embodiment, which is connect by a speed-ratio regulation component 80 with 20 bias of main shaft.Please refer to figure 3, the speed-ratio regulation component 80 include positioned at outside dial 81, be stacked at 81 inside of the dial and be set on main shaft 20 Control panel 82 and positioned at the bolt 83 control panel 82 inside and be inserted on bracket 10.The dial 81 is circular discs, wherein The heart is equipped with a circular perforation 810.The outer surface of the dial 81 be equipped with scale, please refer to Fig. 4, the dial 81 it is interior Surface forms an eccentric groove 811 extended along the periphery of perforation 810 in centrifugal direction.Please refer to Fig. 5, which is With an equal amount of disk of dial 81, a strip groove 820 which is provided with, it is sliding that one is slideably contained in the strip groove 820 Block 821, the surface of the sliding block 821 have protruded outward a convex block 822.After the dial 81 is covered in control panel 82, convex block 822 It is contained in eccentric groove 811 and can be slided along eccentric groove 811, and by a screw 85 successively across the top of connecting rod 40 and scale The perforation 810 of disk 81 and so that its end is screwed togather the middle part for being fixed on the sliding block of control panel 82, the head of screw 85 is resisted against perforation On the connecting rod 40 in 810 outsides.Multiple hole bodies 823 worn for bolt 83 are additionally provided in the control panel 82.The pin rod of the bolt 83 Be arranged on bracket 10 and make its end correspond to control panel 82 hole body setting, the bolt 83 on the pin rod of its plunger side also It is arranged with spring 86, the both ends of the spring 86 can be fixed with plunger and 10 phase of bracket respectively.

When using the speed-ratio regulation component 80, the screw in first 81 outside of rotary dial loosens it suitably, can be by inserting Pin 83 is arranged in the hole body 823 of control panel 82 and positions control panel 82, is rotated further by the centrifugation that dial 81 passes through its inner surface Slot 811 drives convex block 822 and moves with movable slider 821 along strip groove 820, to keep the screw being arranged on sliding block 821 separate Or close to the center of main shaft 20, and then the center for the separate or close main shaft 20 in top for reaching connecting rod 40, that is, realize connecting rod 40 The eccentric distance on top and main shaft 20, the revolving speed for thus controlling idler wheel improve its versatility to be adapted to different machines.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model Protection scope within.
