Abstract
The invention relates to a sewing machine belt pulley device which is provided with a transmission shaft. A bearing is sleeved in the middle of the transmission shaft. A hand wheel capable of being connected with a belt is fixed at the end of the transmission shaft. A bearing block is fixed outside the bearing. A guide groove is formed outside the bearing block. A protective cover capable of covering the handle wheel is slidably disposed in the guide groove. The sewing machine belt pulley device is simple in structure, the handle wheel can be covered by the protective cover during rotation, workers are prevented from being damaged by the hand wheel, and the safety coefficient of a sewing machine is increased.
Description
Technical field
The present invention relates to Sewing machines field, relate in particular to a kind of belt pulley for sewing machine device.
Background technology
Belt pulley for sewing machine device is one of important accessory on Sewing machines, and it is arranged on Sewing machines table one side, by driving belt by the transmission of power of motor to Sewing machines drive link, make sewing machine needle carry out work.
Handwheel in existing belt pulley for sewing machine device is all directly exposed to outside, although facilitate like this operation when manual, in course of normal operation, because its rotating speed is also than comparatively fast, therefore has certain danger.
Summary of the invention
Technical problem to be solved by this invention is that a kind of belt pulley for sewing machine device that can improve handwheel safety coefficient is provided.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: a kind of belt pulley for sewing machine device, there is power transmission shaft, described power transmission shaft intermediate housing is equipped with bearing, end is fixedly installed the handwheel that can connect belt, described bearing external stability is provided with bearing block, and bearing block is outside equipped with gathering sill, in described gathering sill, slides and is provided with the guard shield that can cover handwheel.
Compared with prior art, usefulness of the present invention is: this belt pulley for sewing machine apparatus structure is simple, can in hand wheel rotating process, with guard shield, be covered, and prevents that hand wheel rotating from damaging staff, has improved the safety coefficient of Sewing machines.
accompanying drawing explanation:
Below in conjunction with accompanying drawing, the present invention is further described.
Fig. 1 is belt pulley for sewing machine apparatus structure cutaway view of the present invention.
In figure: 1, handwheel; 2, power transmission shaft; 3, bearing; 4, bearing block; 5, gathering sill; 6, guard shield.
the specific embodiment:
Below in conjunction with the drawings and the specific embodiments, describe the present invention:
A kind of belt pulley for sewing machine device shown in Fig. 1, there is power transmission shaft 2, described power transmission shaft 2 intermediate housing are equipped with bearing 3, end is fixedly installed the handwheel 1 that can connect belt, described bearing 3 external stabilities are provided with bearing block 4, bearing block 4 is outside equipped with gathering sill 5, and the interior slip of described gathering sill 5 is provided with the guard shield 6 that can cover handwheel 1.
Its specific works mode is as follows, while manually using handwheel 1, guard shield 6 is moved to the left by gathering sill 5, and handwheel 1 is exposed, and can use, if handwheel need be covered, directly guard shield 6 is passed to the right, makes guard shield 6 be covered in handwheel 1 outside.
This belt pulley for sewing machine apparatus structure is simple, can in handwheel 1 rotation process, with guard shield 6, be covered, and prevents that handwheel 1 rotation from damaging staff, improved the safety coefficient of Sewing machines.
It is emphasized that: be only preferred embodiment of the present invention above, not the present invention is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present invention is done above embodiment, all still belong in the scope of technical solution of the present invention.
