Abstract
The utility model belongs to Sewing machines accessory technical field, refer in particular to a kind of sewing machine hand-wheel with anti-skidding projection, include handwheel, outer surface in the outer ring of handwheel is or/and inner surface is provided with the anti-skidding projection of a circle, the utility model structure is simple, handwheel is provided with double wedge or shaggy tooth, add the frictional force between hand and handwheel, convenient operation personnel catch handwheel, no matter be that operating personnel's hand-power is less, or when having oil on hand, or Sewing machines torsional moment larger time, all can avoid the phenomenon of skidding, conveniently rotate handwheel, be specially adapted to women operating personnel.
Description
Technical field:
The utility model belongs to Sewing machines accessory technical field, refers in particular to a kind of sewing machine hand-wheel with anti-skidding projection.
Background technology:
When manual operation Sewing machines, be rotate the handwheel running of Sewing machines with hand.The outer surface of existing sewing machine hand-wheel outer ring is the face of cylinder in a light face, and inner surface is also smooth ring surface.What need during operation to grab with hand very tightly could rotate handwheel, otherwise easily skids, and cannot carry out manual operation.When the hand-power of operator (especially general women operator) is less, or when having oil on hand, or when Sewing machines torsional moment is larger, more easily there is the situation of skidding, affect work.
Summary of the invention:
The purpose of this utility model be to provide a kind of structure simple, make operator more easily catch handwheel when rotating and avoid the sewing machine hand-wheel of the anti-skidding projection of band of skidding.
The utility model is achieved in that
With a sewing machine hand-wheel for anti-skidding projection, include handwheel, the outer surface in the outer ring of handwheel is or/and inner surface is provided with the anti-skidding projection of a circle.
Above-mentioned anti-skidding projection is double wedge or shaggy tooth.
Above-mentioned double wedge is straight-tooth or knuckle-tooth.
Above-mentioned shaggy tooth is straight-tooth or knuckle-tooth.
Above-mentioned anti-skidding projection is circumferential uniform and spaced raised line.
The advantage that the utility model is given prominence to compared to existing technology is:
The utility model structure is simple, handwheel is provided with double wedge or shaggy tooth, add the frictional force between hand and handwheel, convenient operation personnel catch handwheel, no matter are that operating personnel's hand-power is less, or when having oil on hand, or Sewing machines torsional moment larger time, all can avoid the phenomenon of skidding, conveniently rotate handwheel, be specially adapted to women operating personnel.
Accompanying drawing illustrates:
Fig. 1 is that the outer ring outer surface of handwheel of the present utility model arranges one of scalloped schematic diagram;
Fig. 2 is that the outer ring outer surface of handwheel of the present utility model arranges scalloped schematic diagram two;
Fig. 3 is that the inner surface of the outer ring of handwheel of the present utility model arranges scalloped schematic diagram;
Fig. 4 is the schematic diagram that the inner surface of the outer ring of handwheel of the present utility model is provided with straight-tooth;
Fig. 5 is one of outer ring outer surface schematic diagram being provided with straight-tooth of handwheel of the present utility model;
Fig. 6 is the schematic diagram two that the outer ring outer surface of handwheel of the present utility model is provided with straight-tooth.
Detailed description of the invention:
With specific embodiment, the utility model is further described below, see Fig. 1-6:
With a sewing machine hand-wheel for anti-skidding projection, include handwheel 1, the center of handwheel 1 is provided with installing hole 5, and the outer surface 6 of the outer ring 2 of handwheel 1 is provided with the anti-skidding projection of a circle; Or the inner surface 7 of handwheel 1 outer ring 2 is provided with the anti-skidding projection of a circle; Or the outer surface 6 in handwheel 1 outer ring 2 and inner surface 7 are respectively arranged with the anti-skidding projection of a circle.
Above-mentioned anti-skidding projection is double wedge or shaggy tooth.
Above-mentioned double wedge is straight-tooth 3 or knuckle-tooth 4.
Above-mentioned shaggy tooth is straight-tooth 3 or knuckle-tooth 4.
Above-mentioned anti-skidding projection is circumferential uniform and spaced raised line.Raised line can be arranged vertically, also can be obliquely installed, and raised line and tab parallel are arranged.
The outer ring 2 of anti-skidding projection of the present utility model and handwheel 1 is integrated, can be also split-type structural, is fixedly connected with by glue, screw etc.
The setting of anti-skidding projection, when rotating handwheel, increases the frictional force between hand, when operating personnel's hand-power is less, or when having oil on hand, or when Sewing machines torsional moment is larger, the situation of skidding all not easily occurs.
Above-described embodiment is only one of preferred embodiment of the present utility model; not limit practical range of the present utility model with this; therefore: all equivalence changes done according to shape of the present utility model, structure, principle, all should be covered by within protection domain of the present utility model.
Claims (1)
