Abstract
The utility model discloses a novel pressure device of a sewing machine. The pressure device comprises a supporting seat, a screw hole, an adjusting screw, a pressure adjusting rod and a pressure spring, wherein the screw hole, the adjusting screw, the pressure adjusting rod and the pressure spring are arranged on the supporting seat. The pressure spring is sleeved on the pressure adjusting rod, flattening protrusions are arranged on the pressure adjusting rod, the pressure adjusting rod is vertically arranged on one side of the screw hole, and the adjusting screw is screwed into the other side of the screw hole. The adjusting screw is abutted against the upper end of the pressure adjusting rod, and the dimension of the contour of the flattening protrusions is smaller than the pore diameter of the screw hole and larger than the outer diameter of the pressure spring. The length of the section contour of the flattening protrusion on a supporting rod is slightly larger than the outer diameter of the pressure spring and slightly smaller than the pore diameter of the screw hole. Due to the fact that the flattening protrusions and the pressure adjusting rod are integrated, pressure of the pressure adjusting rod to the pressure spring is stable, the pressure adjusting rod and the pressure spring can be taken out upwards from the screw hole easily in the process of maintaining, later maintenance time can be saved greatly, and meanwhile maintaining difficulty can be reduced greatly.
Description
Technical field
The utility model relates to the industrial sewing machine technical field, is specifically related to a kind of novel sewing machine pressure apparatus.
Background technology
In the structure of Sewing machines, for guaranteeing the Sewing machines normal operation, must there be suitable pressure of pressure apparatus transmission to make material to be sewn with normal force feed.At present, its supporting seat of the pressure apparatus of conventional art Kong Weitai that tightens up a screw is little, be used for keeping off at the maximum outside diameter of the projecting part of compression spring one end greater than the screw hole position, and be the riveted joint of split cylinder, cause the production assembling process inconvenient, the long-term use has the loose or dislocation phenomenon, and maintenance is very difficult later on.Therefore, practicality, economy on production efficiency and working service have been restricted to a certain extent.
The utility model content
The purpose of this utility model is, for above-mentioned deficiency, provide that a kind of structural design is ingenious, reasonable, cost is low, be easy to realize and maintenance cost low, use more reliable and more stable novel sewing machine pressure apparatus.
for achieving the above object, technical scheme provided by the utility model is: a kind of novel sewing machine pressure apparatus, comprise supporting seat, it also comprises the screw that is arranged on supporting seat, set screw, pressure adjusting lever and pressure spring, described pressure spring is set on described pressure adjusting lever, at least be provided with one on described pressure adjusting lever and be used for gear in the flattening projection of described pressure spring upper end, pressure adjusting lever vertically is arranged on a side of described screw, the opposite side of screw screws in described set screw, and this set screw is pressed on the upper end of pressure adjusting lever, flatten the appearance profile size of projection less than the aperture of described screw, flatten the appearance profile size of projection greater than the overall diameter of pressure spring.
As a kind of improvement of the present utility model, described flattening projection and described pressure adjusting lever are the integral type structure.
As a kind of improvement of the present utility model, the quantity of described flattening projection is two, and two are flattened projection and are symmetricly set on pressure adjusting lever.
The beneficial effects of the utility model are: the utility model design is ingenious, reasonable, be located at the external diameter that its appearance profile size of flattening projection on support bar is slightly larger than pressure spring, and more smaller than the aperture of screw hole, flattening projection and pressure adjusting lever is the integral type structure, this structure make pressure adjusting lever to pressure spring to compress power more stable, when safeguarding, pressure adjusting lever and pressure spring can easily up take out from screw, greatly save later maintenance time, maintenance difficulties reduces greatly simultaneously.And terminal with compact integral structure of the present utility model, compactness, being easy to realize, cost is low, is beneficial to wide popularization and application.
Below in conjunction with accompanying drawing and embodiment, the utility model is further illustrated.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
referring to Fig. 1, a kind of novel sewing machine pressure apparatus that the present embodiment provides, comprise supporting seat 1, it also comprises the screw 11 that is arranged on supporting seat 1, set screw 2, pressure adjusting lever 3 and pressure spring 4, described pressure spring 4 is set on described pressure adjusting lever 3, at least be provided with one on described pressure adjusting lever 3 and be used for gear in the flattening projection 31 of described pressure spring 4 upper ends, pressure adjusting lever 3 vertically is arranged on a side of described screw 11, the opposite side of screw 11 screws in described set screw 2, and this set screw 2 is pressed on the upper end of pressure adjusting lever 3, flatten the appearance profile size of projection 31 less than the aperture of described screw 11, flatten the appearance profile size of projection 31 greater than the overall diameter of pressure spring 4.
Described flattening projection 31 is the integral type structure with described pressure adjusting lever 3.
The quantity of described flattening projection 31 is two, and two are flattened projection 31 and are symmetricly set on pressure adjusting lever 3.
During use, be slightly larger than the external diameter of pressure spring 4 due to flattening projection 31 its appearance profile sizes, but the aperture than screw hole 11 is smaller, flattening projection 31 is the integral type structure with pressure adjusting lever 3, when regulating pressure, turn set screw 2, the effect by this structure make 3 pairs of pressure springs 4 of pressure adjusting lever to compress power more stable; When safeguarding, screw out set screw 2, pressure adjusting lever 3 and pressure spring 4 can easily up take out from screw, greatly save later maintenance time, and maintenance difficulties reduces greatly simultaneously.
As described in the utility model above-described embodiment, adopt structure same or similar with it and other pressure apparatus of obtaining, all in the utility model protection domain.
Claims (3)
