Abstract

The utility model is related to a kind of rolling screen door and opened Door by Hand hand lever, including shaft, the loop-hook with opening, handle and handle；The loop-hook is located at one end of shaft, and the shaft that handle is located above the other end of shaft, handle forms U-shaped handle of the opening towards side to side bending.The utility model is dedicated for manually opened rolling screen door.

Description

A kind of rolling screen door opens Door by Hand hand lever

Technical field

The utility model is related to rolling screen door technical field, more particularly to a kind of rolling screen door opens Door by Hand hand lever.

Background technology

Electric rolling door lifting is driven by door roller, and door roller typically on the supporting plate at the upper side of door opening, passes through Transmission mechanism drives spool turns, and reel drives the door curtain being wrapped on reel to slide up and down to realize switch along door curtain guide rail Door.When running into power failure, it is desirable to have special Manual door opener carrys out switch gate, otherwise rolling screen door cannot be opened and closed. A kind of existing rolling screen door Manual door opener, worm gear wheel is driven with worm screw, and worm gear drives spool turns to be opened Door by Hand to realize, The lower end of the worm screw of the device is provided with an annulus, when opening Door by Hand, and need to have a special enabling hand lever to hook annulus and rotate and carry out band Dynamic worm screw rotates.

Utility model content

The utility model provides a kind of enabling hand lever dedicated for manually opened rolling screen door.

The utility model is achieved through the following technical solutions：

A kind of rolling screen door opens Door by Hand hand lever, including shaft, the loop-hook with opening, handle and handle；The loop-hook Located at one end of shaft, the shaft that handle is located above the other end of shaft, handle forms opening towards side to side bending U-shaped handle.

When wanting manually opened rolling screen door, loop-hook is hooked on the annulus of worm end, one is held stop handle, another Hand rotates handle, and loop-hook just drives annulus to rotate, and is opened Door by Hand so that worm screw rotates realization.

Further, sleeve is provided with outside the handle, the sleeve and handle gap coordinate.Passed through with holding outside sleeve When handle rotates shaft, turn over more smooth.

Further, the U-shaped bottom outer of the handle is provided with sleeve, and the sleeve and handle gap coordinate.Covered with holding When cylinder outside rotates handle drive shaft rotation, turn over more smooth.

The beneficial effects of the utility model are：Using the loop-hook with opening and opening towards the U-shaped handle of side, pass through Loop-hook hooks the annulus of worm end, and rotating handle can manually opened rolling screen door.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model.

Embodiment

Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that advantage of the present utility model It can be easier to be readily appreciated by one skilled in the art with feature, so as to make protection domain of the present utility model apparent clear and definite Define.

As shown in figure 1, embodiment of the present utility model, a kind of rolling screen door opens Door by Hand hand lever, including shaft 1, band opening Loop-hook 2, handle 3 and handle 4；The loop-hook 2 is located at one end of shaft 1, and handle 3 is located at the other end of shaft 1, handle The shaft 1 of 3 tops forms U-shaped handle 4 of the opening towards side to side bending.

When wanting manually opened rolling screen door, loop-hook 2 is hooked on the annulus of worm end, one is held handle 3 of stopping, another Hand rotates handle 4, and loop-hook 2 just drives annulus to rotate, and is opened Door by Hand so that worm screw rotates realization.

The outside of handle 3 is provided with sleeve 5, and the sleeve 5 and the gap of handle 3 coordinate.With holding in the outside of sleeve 5 by turning When rotating shaft 14, turn over more smooth.

The U-shaped bottom outer of the handle 4 is provided with sleeve 5, and the sleeve 5 and the gap of handle 4 coordinate.With holding in sleeve 5 When outside rotates the drive rotation of shaft 1 of handle 4, turn over more smooth.

It is described above, embodiment only of the present utility model, but protection domain of the present utility model do not limit to In this, any change or replacement expected without creative work should all be covered within protection domain of the present utility model. Therefore, protection domain of the present utility model should be determined by the scope of protection defined in the claims.
