Abstract
The utility model provides a feed lifting forked connection of a sewing machine, belongs to the technical field of manufacturing of the sewing machine, and solves the problems of high probability of movement of a connection blank, large noise and the like during work of the lifting forked connection of the sewing machine in the prior art. The feed lifting forked connection of the sewing machine comprises a cylindrical mounting part and a forked body which is connected with the mounting part into a whole, wherein the forked body is arranged on the end part of the mounting part and the end face of the forked body back on to the end is an inner side face; the mounting part is provided with a fracture structure which extends to the inner side face from the end face of the other end of the mounting part; and an elastic connecting piece is formed on the mounting part through the fracture structure. According to the lifting forked connection, the working noise of the sewing machine is effectively reduced, the fixation with a shaft is more firm, and the forked body is more closely matched with the connection blank.
Description
Technical field
The utility model belongs to sewing mechanism technology for making field, relates to a kind of feeding feed lifting fork of Sewing machines.
Background technology
Sewing machines is to use one or more sewing thread, on sewing, forms one or more stitchings, the machine that makes one or more layers sewing interweave or unite by a seam.Along with the continuous innovation of industrial technology, the technology of Sewing machines is also further developed, from early stage manually, develop into electronic, semi-automatic till now or full-automatic again.Though Sewing machines has obtained further development, many parts still need further to improve, thereby improve the performance of machine.
Feed lifting fork is the vitals of Sewing machines linkage; The structure of feed lifting fork directly influences the transmission performance of linkage; Traditional feed lifting fork such as Fig. 1, shown in Figure 2; Its structure comprises installation portion cylindraceous and the fork that fuses with installation portion, and end and the fork that fork the is arranged on installation portion end face of this end dorsad is medial surface.
Traditional feed lifting fork as shown in Figure 3 is after being fixed on axle and going up, and because of whole erection portion fuses with fork, fork opening stressing influence is variable big through the fixing back of screw, causes this position to connect easy becoming flexible, and problem such as noise is excessive.
Summary of the invention
There are the problems referred to above in the utility model to existing technology, has proposed a kind of feeding feed lifting fork of Sewing machines, and this feed lifting fork can effectively reduce Sewing machines work noise, has solved the easy loosening problem that this position causes greatly because of fixedly making the fork opening become.
The utility model is realized through following technical proposal: a kind of feeding feed lifting fork of Sewing machines; Comprise installation portion cylindraceous and the fork that fuses with installation portion; End and the fork that described fork the is arranged on installation portion end face of this end dorsad is medial surface; It is characterized in that, on described installation portion, be provided with the fracture texture that extends to above-mentioned medial surface from the end face of the installation portion other end, on installation portion, form a rubber-like brace through this fracture texture.The feeding feed lifting fork of this Sewing machines is fixed on through installation portion cylindraceous on the axle of feed mechanism of Sewing machines, is containing tooth bud in the fork, when axle rotates, drives the tooth bud swing in the fork through feed lifting fork, and feeding is carried out in the formation link motion.
In the feeding feed lifting fork of above-mentioned Sewing machines, described fracture texture comprises that first fracture and second fracture form and intersect along axial first fracture of installation portion with along second fracture of above-mentioned fork medial surface.This feed lifting fork is provided with two fractures; On the installation portion cylindraceous under brace and the installation portion brace have elasticity; Can fix; Second fracture has been offered in the fork inboard, and the effect of component had not solved fork and become big problem because of the opening that fixedly causes when fixing back fork did not receive two braces fixedly.
In the feeding feed lifting fork of above-mentioned Sewing machines, described first fracture and second fracture are for intersecting vertically.Intersect vertically and make the increase of joint face active area make installation portion fixing more firm.
In the feeding feed lifting fork of above-mentioned Sewing machines, described first fracture and second fracture are all linearly.Fracture linearly is easy to processing, and practicality is good and attractive in appearance.
In the feeding feed lifting fork of above-mentioned Sewing machines; The installation portion of the said first fracture upside is provided with the last connector that fuses with installation portion; The installation portion of the first fracture downside is provided with the following connector that fuses with installation portion; Offer screwed hole at last connector, offering through hole on the connector down, screwed hole is corresponding with through hole.Can penetrating with the cooperation of corresponding screwed hole from lower through-hole of screw is fixed on installation portion on the axle.
In the feeding feed lifting fork of above-mentioned Sewing machines, the aperture of described through hole is greater than the aperture of above-mentioned screwed hole.Because of installation portion is a tubular, design and installation is more convenient like this, and fixed effect is better.
Compared with prior art, title of the present invention has the following advantages: offered fracture in the fork inboard, made that fixing of feed lifting fork is more firm, fork is tightr with cooperating of tooth bud, the noise when effectively reducing swing.

The specific embodiment
Below be the specific embodiment of the utility model, and combine accompanying drawing that technical scheme of the present invention is done further to describe, but the present invention is not limited to these embodiment.
As shown in Figure 1, a kind of feeding feed lifting fork of Sewing machines comprises installation portion 1 cylindraceous and the fork 2 that fuses with installation portion 1; End and the fork 2 that described fork 2 is arranged on installation portion 1 end face of this end dorsad is medial surface; Installation portion 1 is provided with the fracture texture that extends to above-mentioned medial surface from the end face of installation portion 1 other end, on installation portion 1, forms a connecting piece through this fracture texture, and fracture texture comprises along axial first fracture 3 of installation portion with along second fracture 4 of above-mentioned fork medial surface; First fracture 3 and second fracture 4 form and intersect and for intersecting vertically; Two fractures all linearly, the installation portion 1 of first fracture, 3 upsides is provided with the last connector that fuses with installation portion 1, the installation portion 1 of first fracture, 3 downsides is provided with the following connector that fuses with installation portion; Offer screwed hole 5 at last connector; Offering through hole on the connector down, screwed hole 5 is corresponding with through hole, and the aperture of through hole is greater than the aperture of above-mentioned screwed hole 5.
The feeding feed lifting fork of Sewing machines; Be fixed on through installation portion 1 cylindraceous Sewing machines feed mechanism the axle on, containing tooth bud in the fork 2, when Sewing machines is worked; The feed lifting fork that is fixed in the rotating shaft drives the tooth bud swing in the fork, forms link motion and carries out feeding.Be provided with the fracture of offering that extends to the fork medial surface from the end face of installation portion 1 other end because of installation portion 1; Feed lifting fork is fixed in the rotating shaft through screw; Fork 2 does not receive the external force effect; Make that originally to become the noise of the feed lifting fork swing that caused greatly excessive because of fork 2 openings, swing back tooth bud is prone to problem such as loosening and has obtained effective solution.
