Abstract
The utility model provides a rolling door machine gear box that can two -way automatic control is met to hinder and is stopped device promptly, its characterized in that: it is equipped with little sprocket, toggle switch clutch, compression spring and micro -gap switch, rolling door machine's motor output shaft passes through the compression spring transmission and connects the toggle switch clutch, little sprocket is connected in the transmission of toggle switch clutch, at least, it is a slope to have a connection face in little sprocket, toggle switch clutch and the motor output shaft for when connecting the face and taking place to rotate relatively for both of slope, concur axial relative displacement, the toggle switch clutch is connected in the micro -gap switch transmission to the electrically conductive motor of connecting rolling door machine, the feasible micro -gap switch that works as is done the time spent by the toggle switch clutch, and the toggle switch clutch cuts off rolling door machine's dynamo power supply, makes the bring to rest of rolling door machine motor then.
Description
Technical field
This utility model relates to electric screen robling machine, particularly relates to the i.e. stop device that is hampered of electric rolling door device.
Background technology
Chain drive, because its low cost and metastable performance have obtained extensive use, as: electric roll-up door mechanism, but its safety deficiency problem day is aobvious prominent, for electric rolling door, in actual use, in door curtain decline closing process, when rolling door body touches people, animal or article, it is impossible to stop or can not and stopping or bounce-back, directly it will be damaged, also can damage door machine and the motor of rolling screen door simultaneously.
Summary of the invention
In order to overcome above-mentioned defect, the purpose of this utility model there is provided and can the door roller gear-box of two-way installation be hampered i.e. stop device.
For achieving the above object, the technical solution of the utility model is:
It is stop device that a kind of door roller gear-box that can two-way automatically control is hampered, and is provided with minor sprocket, toggle switch clutch, compression spring and microswitch；The motor output shaft of described door roller connects toggle switch clutch by compressing spring transmission, and described toggle switch driven by clutches connects minor sprocket；At least there is a joint face in described minor sprocket, toggle switch clutch and motor output shaft is a slope so that joint face is both of slope when relatively rotating, and axially opposing displacement occurs simultaneously；Described microswitch is in transmission connection toggle switch clutch, and is conductively connected the motor of door roller so that when microswitch is struck switch-clutch effect, and toggle switch clutch cuts off the motor power of door roller, then makes door roller motor out of service.
Described toggle switch clutch is provided with toggle switch first clutch and toggle switch second clutch；Described toggle switch second clutch is in transmission connection toggle switch first clutch；Described switch first clutch is in transmission connection minor sprocket.
The joint face of described toggle switch first clutch and clutch second switch is a slope, and when toggle switch first clutch relatively rotates with clutch second switch, relative motion is axially occurring for toggle switch first clutch and clutch second switch.
Described clutch the first joint face switched with minor sprocket is a slope, and when toggle switch first clutch relatively rotates with minor sprocket, relative motion is axially occurring for toggle switch first clutch and minor sprocket.
Having the beneficial effect that of technique scheme
Basis is novel is provided with slope by the joint face between transmission minor sprocket, toggle switch first clutch, toggle switch second clutch, make when minor sprocket relatively rotates with toggle switch clutch, toggle switch clutch generation axial displacement, and act on microswitch, then cutting off motor power makes it stop, and the purpose namely stopped that realizes being hampered.
Below in conjunction with the drawings and specific embodiments, this utility model is further described.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Detailed description of the invention
Embodiment 1
It is stop device that a kind of door roller gear-box that can two-way automatically control as shown in Figure 1 is hampered, including toggle switch clutch 2, fixing plate 3, microswitch 4, compression spring 5；Described toggle switch clutch 2 is made up of toggle switch first clutch 22, toggle switch second clutch 21；Originally the i.e. stop device that is hampered coordinates with the motor output shaft 6 of described door roller, minor sprocket 1, specific as follows:
Minor sprocket 1, toggle switch second clutch 21, toggle switch first clutch 22 and motor output shaft 6 are sequentially coaxially traditional thread binding joins；Described compression spring 5 is placed on motor output shaft 6, and the two ends of compression spring 5 rely on fixing plate 3 and toggle switch first clutch 22 respectively.
Wherein said toggle switch first clutch 22, toggle switch second clutch 21 contact surface be provided with a slope；Described minor sprocket 1, toggle switch second clutch 21 contact surface be provided with a slope.
Operation principle:
When electrical power, output hexagonal axis drives toggle switch clutch 1 to rotate, and stirs exploitation clutch 1 and drives transmission minor sprocket；Driving chain is passed through in minor sprocket transmission, carries out the big sprocket wheel of transmission and rotates；Big sprocket wheel has driven spool operation, drives door curtain to rise simultaneously.
When door curtain meets obstructions, minor sprocket and toggle switch clutch 1 promote toggle switch clutch 2 together, toward being pushed up, have promoted compression spring and have pushed up microswitch 2；Microswitch 2 receives thrust, has cut off on and off switch, and namely motor is out of service！
When door curtain down runs and meets obstructions, minor sprocket drives toggle switch clutch 1, and toward lifting force, microswitch 1 action is arrived on top；Microswitch 1 one work is switched off on and off switch, and namely motor is out of service.
Embodiment 2
A kind of door roller gear-box that can two-way automatically control is hampered as described in Example 1 is stop device, slope between described toggle switch second clutch 21, toggle switch first clutch 22 and motor output shaft 6, is arranged on the contact surface between toggle switch first clutch 22 and motor output shaft 6.
Claims (4)
1. it is stop device that the door roller gear-box that can two-way automatically control is hampered, it is characterised in that: it is provided with minor sprocket, toggle switch clutch, compression spring and microswitch；The motor output shaft of described door roller connects toggle switch clutch by compressing spring transmission, and described toggle switch driven by clutches connects minor sprocket；At least there is a joint face in described minor sprocket, toggle switch clutch and motor output shaft is a slope so that joint face is both of slope when relatively rotating, and axially opposing displacement occurs simultaneously；Described microswitch is in transmission connection toggle switch clutch, and is conductively connected the motor of door roller so that when microswitch is struck switch-clutch effect, and toggle switch clutch cuts off the motor power of door roller, then makes door roller motor out of service.
