Abstract
The invention discloses a coupler of a sewing machine. The coupler is provided with a positioning rod. A thread for fixing is arranged at the head of the positioning rod. A hollow shaft is sleeved outside the tail end of the positioning rod. A bevel gear is arranged at the head of the hollow shaft, and an outwards-protruding bayonet is arranged at the tail end of the hollow shaft. The bevel gear is provided with a positioning bolt. The coupler provided by the utility model has the advantages of simple structure, good transmission effect, long service life and convenience in maintenance.
Description
Technical field
The present invention designs the Sewing machines transmission field, relates in particular to a kind of Sewing machines shaft coupling.
Background technology
Along with the continuous progress of science and technology and improving constantly of the price of labour power, original treadle type sewing machine is replaced by electric sewing machine gradually.Existing electric sewing machine provides power by the stepper motor that is installed on the Sewing machines, connecting gear-box by belt operates, the main drive gear of gear-box mainly carries out transmission by shaft coupling, existing sewing machine shaft coupling gear slides easily, and transmission instability, service life is short, influence processing.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of use transmission effective, the Sewing machines shaft coupling of long service life.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: a kind of Sewing machines shaft coupling, has backstay, described backstay head is provided with the screw thread that is used for fixing, terminal outer cover is connected to hollow shaft, described hollow shaft head is provided with bevel gear, and end is provided with outwards outstanding bayonet socket.
Further, described bevel gear is provided with bolt
Compared with prior art, usefulness of the present invention is: this Sewing machines coupler structure is simple, and transmission is effective, long service life, and maintain easily.
Description of drawings:
The present invention is further described below in conjunction with accompanying drawing.
Fig. 1 is a kind of Sewing machines coupler structure of the present invention schematic diagram.
Among the figure: 1, backstay; 11, screw thread; 2, hollow shaft; 21, bayonet socket; 3, bevel gear; 4, bolt.
The specific embodiment:
Describe the present invention below in conjunction with the drawings and the specific embodiments:
A kind of Sewing machines shaft coupling shown in Figure 1 has backstay 1, and described backstay 1 head is provided with the screw thread 11 that is used for fixing, and terminal outer cover is connected to hollow shaft 2, and described hollow shaft 2 heads are provided with bevel gear 3, and end is provided with outwards outstanding bayonet socket 21; Fixing and for convenience detach in order to make between bevel gear 3 and the hollow shaft 2, described bevel gear 3 is provided with bolt 4.
This Sewing machines coupler structure is simple, and transmission is effective, long service life, and maintain easily.
It is emphasized that: above only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment did.
