Abstract
The utility model relates to a limit mechanism, in particular to a limit mechanism used for limiting door rolling position by a motor-driven door roller. The limit mechanism comprises a transmission screw, a left side journey switch, a right side journey switch, a left nut, a right nut, a clamping plate and a casing. The transmission screw is fixedly connected onto the casing and capable of rotating around the axis of the casing. The left side journey switch and the right side journey switch are arranged on a base plate of the casing and respectively located on two lateral end portions of a spiral belt of the transmission screw. The left nut and the right nut are fixedly connected onto the transmission screw and located between the two side journey switches, and a clamping groove is arranged on the cylindrical face of the left nut and the right nut. The clamping plate is fixedly connected onto the base plate of the casing and connected in the clamping grooves of the left nut and the right nut. When the motor-driven door roller lifts a roller shutter door to the preset height, the location nuts touch the journey switches which send out electric signals, and an execution mechanism locks the roller shutter door at certain height.
Description
Technical field
The utility model relates to a kind of position-limit mechanism, particularly a kind ofly is used for the position-limit mechanism that electric roll-up door mechanism limits the rolling door position.
Background technology
The position-limit mechanism that adopts in the door-rolling machine commonly used on the market at present is a Spring Card chip stop; Comprise slotted nut, card slide bolt, positioning bolt etc.; Its complex structure, pretty troublesome when the setting rolling door hoists the position, and it adopts single positioning bolt; Locate fully inadequately, the locator failure state can occur in some cases; The card slide bolt is easy to stuckly in its work engineering besides, and is difficult to open, and dismounting is very inconvenient.
The utility model content
It is simple that the utility model technical problem to be solved provides a kind of mechanism, and the position-limit mechanism of electromechanical integration is easily debugged in operation.
For solving the problems of the technologies described above, the utility model is realized as follows: the position-limit mechanism of the said a kind of electric roll-up door mechanism of the utility model comprises drive screw, left side travel switch, right side travel switch, left nut, right nut, clamp and housing; Said drive screw is fixedly connected on the housing, and can be around its rotational; Said left side travel switch and right side travel switch are provided with on the housing base plate, lay respectively at drive screw hurricane band both side ends; Said left nut and right nut are fixedly connected on the drive screw, and between the travel switch of both sides, the face of cylinder of left and right nut is provided with draw-in groove; Said clamp is fixedly connected on the housing base plate, and is connected in the draw-in groove of left nut and right nut.
The end of said drive screw is fixedly connected with sprocket wheel.
Said left side travel switch is provided with contact a, and the right side travel switch is provided with contact b; Left side travel switch and right side travel switch electrically connect through power line and electric machine controller formation.
The good effect of the utility model: the position-limit mechanism of the said a kind of electric roll-up door mechanism of the utility model is simple in structure, and the adjustment setscrew nut is easy, has simplified debug process greatly; Card is fixing reliable, has improved the reliability of location; This device adopts the sensor of mechanical switch formula, stable performance, and signal feedback speed also receives the influence of component vibrations such as motor in operation soon, and the life-span is long, has improved overall performance greatly.

The specific embodiment
Like Fig. 1, shown in Figure 2, the position-limit mechanism of the said a kind of electric roll-up door mechanism of the utility model comprises drive screw (1), left side travel switch (3), right side travel switch (5), left nut (9), right nut (8), clamp (10) and housing (7); Said drive screw (1) is fixedly connected on the housing (7), and can be around its rotational, and the end of drive screw (1) is fixedly connected with sprocket wheel (2), and sprocket wheel (2) is a power intake, and it is followed the rolling door rise and falls forward or reverse; Said left side travel switch (3) and right side travel switch (5) are provided with on housing (7) base plate, lay respectively at drive screw (1) hurricane band both side ends; Left side travel switch (3) is provided with contact a (4), and right side travel switch (5) is provided with contact b (6); Left side travel switch (3) and right side travel switch (5) electrically connect through power line and electric machine controller formation.
Left side nut (9) and right nut (8) are fixedly connected on the drive screw (1), and between the travel switch of both sides, the face of cylinder of left and right nut is provided with draw-in groove; Clamp (10) is fixedly connected on housing (7) base plate, and is connected in the draw-in groove of left nut (9) and right nut (8); In the process of drive screw (1) forward or reverse, left nut (9) and right nut (8) will axially move to left or move to right along drive screw (1) simultaneously, after its side touches travel switch, get final product triggering signal.
The course of work of the utility model:
During debugging, at first set the extreme position of rolling door, the position of setscrew nut in the position-limit mechanism be set, can the left and right side travel switch be inserted various signals respectively and represent two different positions of rolling door according to extreme position, promptly topmost with bottom; When electric roll-up door mechanism is elevated to preset height with rolling door, setscrew nut will be touched travel switch, and travel switch promptly sends the signal of telecommunication, and executing agency fixes on rolling screen door lock on the certain altitude; In order to ensure normal and stable operation in the whole process, we must guarantee that setscrew nut has only move left and right and can not rotate on screw rod, so the effect of clamp is just very crucial; When needs adjustment rolling screen door lock allocation, need at first pull down clamp, then just can about turn setscrew nut, make it arrive correspondence position, then load onto clamp, and guarantee in its draw-in groove that is connected in left nut and right nut.
Some principles of work and power of the position-limit mechanism of the relevant a kind of electric roll-up door mechanism of the utility model that just explains through diagrams recited above; Owing to concerning the technician in constructed field, be easy to carry out on this basis some modifications; Therefore this manual do not really want position-limit mechanism with the described a kind of electric roll-up door mechanism of the utility model be confined to shown in or in the described concrete mechanism and the scope of application; So every modify that possibly be utilized and equivalent, all belong to the protection domain of the utility model patent.
