Description
Technical field
The utility model belongs to technical field of sewing equipment, is specifically related to a kind of Multifunctional leather belt wheel of Sewing machines.
Background technology
Sewing machines has hand-rail type, foot-operated, driven type, hand-rail type and the Sewing machines of driven type be generally all made up of head, support, transmission and annex four part, wherein the running part of Sewing machines is made up of parts such as frame, hand-operated device or motor.All there are pluses and minuses in the Sewing machines of different driving mode, Sewing machines as driven type can not use when having a power failure, the effort of hand-rail type, so there is people just to propose a kind of multifunctional usage Sewing machines, electricity driven on formula and hand-rail type collection Sewing machines, make it under having electricity, not having electric situation, can normally use, but existing electricity drive formula and hand-rail type Sewing machines and belt pulley syndeton on can be variant, make it can not share a belt pulley, make the conversion of Sewing machines type of drive become trouble.
Utility model content
The purpose of this utility model is the above-mentioned defect of the shell for existing Sewing machines, and the Multifunctional leather belt wheel, particularly a kind of hand-operated device that disclose a kind of Sewing machines drive, with changing Multifunctional leather belt wheel easily between each type of drive of electric drive.
The purpose of this utility model realizes by following technical proposal:
A kind of Multifunctional leather belt wheel of Sewing machines, comprise wheel body, wheel body is rotationally connected by the head of rotating shaft and Sewing machines, wheel body is provided with a circle belt grooves, it is characterized in that, described belt pulley also comprises a wheel rim, wheel body and wheel rim are arranged before and after rotating shaft axially, the size of wheel rim internal diameter is greater than wheel body outside dimension, multiple spoke is interval with between wheel rim and wheel body, one end and the wheel rim inwall of each spoke are connected, the other end bends towards wheel body direction and extends and be finally fixed on the lateral surface of wheel end of body, the bayonet socket for hand-operated device clamping is formed between adjacent two spokes.Form a cavity caved between wheel rim and end, wheel body outer end, can be arranged on wherein for the actuating arm of hand-operated device, make whole mechanism compacter and improve security.
In the Multifunctional leather belt wheel of above-mentioned a kind of Sewing machines, described spoke radially distributes setting.
In the Multifunctional leather belt wheel of above-mentioned a kind of Sewing machines, the width of described bayonet socket is to interior and to broaden gradually outward.
In the Multifunctional leather belt wheel of above-mentioned a kind of Sewing machines, described each spoke is curved.
Compared with prior art, the utility model owing to being provided with the structure such as bayonet socket for hand-operated device clamping between adjacent two spokes, make its when having a power failure can easily and fast with converting between electric drive and hand-operated device type of drive, structure is simple, easy to operate.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
