Abstract
The utility model relates to a rolling door machine stopper, the gear be connected including the casing, with rolling door machine drive mechanism, run through screw rod that casing and gear shaft be connected, adorn slotted nut, inserted sheet on the screw rod, one side of screw rod is located to the inserted sheet, through the fix with screw on the baseplane of casing, one side of this inserted sheet and screw rod are parallel to be injected in slotted nut's the fluting, the both ends of screw rod respectively are equipped with a correlation formula photoelectric sensor, correlation formula photoelectric sensor's transmitter and the both sides that the screw rod was located to the receiver branch, the height that highly is less than slotted nut of its correlation light. The utility model discloses can avoid arousing owing to the ablation of mechanical fatigue and the inside electric contact of travel switch that control is malfunctioning.
Description
Technical field
This utility model relates to a kind of stop, particularly relates to a kind of door roller stop.
Background technology
Electric rolling door is at StoreFront, it is used widely in the places such as garage, can be automatically stopped when electric rolling door is elevated to precalculated position, this function is completed by door roller stop, existing door roller stop is typically by the gear driven screw rod rotation connected with door roller drive mechanism, make the slide block on screw rod axially move and touch travel switch, travel switch sends the signal of telecommunication, thus stop door roller and run, mechanical type is typically used due to travel switch, after use after a while, due to mechanical fatigue and the ablation of travel switch internal electrical contact, travel switch can be malfunctioning, once travel switch is malfunctioning, door roller would not stop in precalculated position, cause damage.
Utility model content
This utility model overcomes the deficiencies in the prior art, it is provided that a kind of can overcome mechanical fatigue and electric contact ablation, reliable door roller stop.
This utility model is achieved through the following technical solutions:
A kind of door roller stop, the gear being connected with door roller drive mechanism including housing, runs through the screw rod that housing is connected, the slotted nut being contained on screw rod, inserted sheet with gear shaft；Described inserted sheet is located at the side of screw rod, is fixed by screws on the baseplane of housing, and this inserted sheet parallel with screw rod also injects the fluting of slotted nut；Described screw rod be respectively arranged at the two ends with a correlation photoelectric sensor, the emitter of described correlation photoelectric sensor and receptor are divided into the both sides of screw rod, and the height of its correlation light is less than the height of slotted nut.When door roller drive mechanism driven gear rotates, screw rod and then rotates, the slotted nut being contained on screw rod is owing to inserting inserted sheet in fluting, so can only axially move, when slotted nut moves to the two ends of screw rod, owing to the correlation light of the aspect ratio correlation photoelectric sensor of slotted nut is high, slotted nut has just blocked the correlation light of correlation photoelectric sensor, correlation photoelectric sensor just sends the signal of telecommunication to door roller controller, stops door roller and runs.Such as the stop position of rolling screen door to be adjusted, the screw on inserted sheet can be unclamped, take off inserted sheet, rotate slotted nut, adjust slotted nut initial position on screw rod, after having adjusted, fix inserted sheet again.
Further, described slotted nut is provided with two.One enabling stop position being used for arranging rolling screen door, another is used for arranging stop position of closing the door.
Further, described screw rod is positioned at the junction of gear side and housing and is provided with bearing.On the one hand this bearing is easy to the rotation of screw rod, on the other hand coordinates the convex shoulder on screw rod to play the role of positioning screw rod.
The beneficial effects of the utility model are: arrange correlation photoelectric sensor at the two ends of screw rod and replace traditional mechanical stroke switch, can avoid causing travel switch malfunctioning due to mechanical fatigue and the ablation of travel switch internal electrical contact, and then it is malfunctioning to cause stop to control, stop is made to run relatively reliable.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model a kind of door roller stop.
Detailed description of the invention
Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus protection domain of the present utility model is made apparent clear and definite defining.
As it is shown in figure 1, a kind of door roller stop, the gear 2 that is connected with door roller drive mechanism including housing 1, run through the screw rod 3 that housing 1 is connected, the slotted nut 4 being contained on screw rod 3, inserted sheet 5 with gear shaft；Described inserted sheet 5 is located at the side of screw rod 3, is fixed on the baseplane of housing 1 by screw 6, and this inserted sheet 5 parallel with screw rod 3 also injects the fluting of slotted nut 4；Described screw rod 3 be respectively arranged at the two ends with a correlation photoelectric sensor 7, the emitter 71 of described correlation photoelectric sensor 7 and receptor 72 are divided into the both sides of screw rod 3, and the height of its correlation light is less than the height of slotted nut 4.When door roller drive mechanism driven gear 2 rotates, screw rod 3 and then rotates, the slotted nut 4 being contained on screw rod 3 is owing to sticking inserted sheet 5 in fluting, so can only axially move, when slotted nut 4 moves to the two ends of screw rod 3, owing to the correlation light of the aspect ratio correlation photoelectric sensor 7 of slotted nut 4 is high, slotted nut 4 has just blocked the correlation light of correlation photoelectric sensor 7, correlation photoelectric sensor 7 just sends the signal of telecommunication to door roller controller, stops door roller and runs.Such as the stop position of rolling screen door to be adjusted, the screw 6 on inserted sheet 5 can be unclamped, take off inserted sheet 5, rotate slotted nut 4, adjust the slotted nut 4 initial position on screw rod 3, after having adjusted, fix inserted sheet 5 again.
Described slotted nut 4 is provided with two.One enabling stop position being used for arranging rolling screen door, another is used for arranging stop position of closing the door.
Described screw rod 3 is positioned at the junction of gear 2 side and housing 1 and is provided with bearing 8.This bearing 8 one aspect is easy to the rotation of screw rod 3, on the other hand coordinates the convex shoulder 9 on screw rod 3 to play the role of positioning screw rod 3.
The above, detailed description of the invention the most of the present utility model, but protection domain of the present utility model is not limited thereto, any change expected without creative work or replacement, all should contain within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims are limited.
