Problems solved by technology

For sewing machines, because the belt will loosen, it is often necessary to tension the belt or change the belt. When changing the belt, some existing pulley protective covers have a complicated structure and complicated disassembly; when the belt is to be tensioned, the position of the belt is different Change, the existing protective cover lacks the function of angle adjustment to adapt to the above situation
The protective cover that lacks the function of angle adjustment cannot be well adapted to the use of different platforms, and the interchangeability is poor

Abstract

The invention provides an angle-adjustable protection shield of a sewing machine motor belt pulley. The protection shield includes a mounting rack fixed to a housing of a sewing machine motor and a protective shell detachably matched with the mounting rack; the protective shell includes a panel and a baffle erected on the brim of the panel, a mounting port connected with the mounting rack is formed in the side, opposite to the penal, of the protective shell, and a containing space used for containing the belt pulley and an opening which is communicated with the containing space and used for enabling a belt to stretch out of the opening are formed in the protective shell; the angle-adjustable protection shield also includes an angle adjusting device used for adjusting the opening orientation of the protective shell. Through the angle adjusting device, the angle of the protection shield can be adjusted conveniently, so that the protection shield is applicable to more sewing machine tables and is high in adaptability. The protective shell of the protection shield is detachable, and after the protective shell is detached, the belt on the belt pulley can be conveniently installed or dismantled.

Description

【Technical field】 [0001] The invention relates to a protective cover for a pulley, in particular to an angle-adjustable protective cover for a sewing machine motor pulley. 【Background technique】 [0002] For general sewing machines, the transmission between the motor and the sewing machine is realized by belts and pulleys. During the high-speed operation of the sewing machine motor, if the sewing worker touches the pulley by mistake, it may cause injury. Therefore, it is necessary to install a protective cover on the pulley. For sewing machines, because the belt will loosen, it is often necessary to tension the belt or change the belt. When changing the belt, some existing pulley protective covers have a complicated structure and complicated disassembly; Changes, the existing protective cover lacks the function of angle adjustment to adapt to the above situation. The protective cover that lacks the function of angle adjustment cannot be well adapted to the use of different ...
