a simple clutch

Abstract

The invention discloses a simple clutch and relates to reeling mechanisms of screen windows. The simple clutch comprises a cap head, a swivel and a rotary shaft, wherein a bolt through hole is formed in the axial center of the cap head, each end face of the cap head is provided with at least one lug, a through hole is formed in the axial center of the swivel, one end face of the swivel is provided with a driving gear, the other end face of the swivel is provided with two grooves which are matched with the lugs on the cap head, the bottom surfaces of the grooves are oblique, a bolt hole is formed in the axial center of the head of the rotary shaft, the diameter of the middle of the rotary shaft is larger than that of the head of the rotary shaft, a driven gear is arranged on the side, close to the head, of the middle of the rotary shaft, the driving gear is matched with the driven gear, the swivel is installed on the head of the rotary shaft in a sleeved mode, the driving gear is opposite to the driven gear, the lugs arranged on the cap head are inserted into the grooves in the swivel, and the cap head and the swivel are connected through a screw and are not locked in a dead mode. The simple clutch is simple in structure and convenient to use.

Description

technical field [0001] The invention relates to a reel mechanism of a screen window, in particular to a simple clutch. Background technique [0002] Clutches are widely used in various mechanical equipment. The structure of the known clutch is either too complicated or the components are too large, so it is not suitable for application on some small devices. With the improvement of people's living standards and the improvement of household conditions, stainless steel doors and windows are basically used. In the past, the screens and windows used with stainless steel doors and windows were more push-pull, which is inconvenient to use. Now most of them use roller shutters. The current rolling screen window uses spring energy storage to realize the automatic winding of the screen window, but the speed of rolling up is too fast, which easily damages the screen window.

Known clutch, its structure is either too complex, or the components are too large, unsuitable for application on some small devices

With the improvement of people's living standards and the improvement of home conditions, stainless steel doors and windows are basically used. In the past, the screens and windows that matched stainless steel doors and windows were more push-pull, which is inconvenient to use. Now most of them use roller shutters.

The current roller screen window uses spring energy storage to realize the automatic winding of the screen window, but the speed of rolling up is too fast, which is easy to damage the screen window

In order to solve this problem, the inventor designed a roller blind screen with damping, which uses the damping force provided by the buffer to make the curtain roll up slowly and softly. The roller shutter screen with damping needs to use a clutch. Due to the need to leave more area for window screens, the parts in the moving device need to be relatively small and simple in structure, but the existing clutches with traditional structures cannot meet the requirements
