Abstract
The invention discloses a lead screw limiter for an electric shutter. The lead screw limiter for the electric shutter comprises a lead screw and lead screw seats arranged at two ends of the lead screw, wherein the lead screw comprises a screw and a slide block nut connected onto the screw in a threaded mode. The screw is driven by a motor of the electric shutter, the end portion of the screw is fixedly connected with a limiting plate, a microswitch electrically connected with a controller is installed on the limiting plate, the controller is electrically connected with the motor, and an ejecting rod for ejecting and pressing the microswitch is installed on the slide block nut. The lead screw limiter for the electric shutter performs limiting through lead screw transmission and is simple in structure and easy to achieve, the stability is ensured, and the manufacture cost is also greatly reduced.
Description
Technical field
The present invention relates to a kind of electric-powered shutter screw rod limiter.
Background technology
Electric-powered shutter, have another name called electric shutter blind, and it,, by the kind of drive of using the lifting of driven by motor blade to replace traditional blind to pull, has breakthrough innovation, makes it easier and follow one's bent in operating process.Stop is one of important component part of electric-powered shutter operation, and therefore, the stability of stop is the key point that guarantees the normal operation of electric-powered shutter.At present, the electric-powered shutter on market, the most less stable of its stop adopted, and cost is higher, thus improved the cost of whole product, reduced its market competitiveness.
Summary of the invention
The object of the invention is to for the problems referred to above, a kind of electric-powered shutter screw rod limiter is provided, solving existing power-operated shutter window stop poor stability, cost is high, the problem that the market competitiveness is low.
The objective of the invention is to be achieved through the following technical solutions:
A kind of electric-powered shutter screw rod limiter, comprise screw mandrel and be arranged on the screw rodb base at screw mandrel two ends, described screw mandrel comprises screw rod and is threaded in the slider nut on screw rod, described screw rod is driven by the motor of electric-powered shutter, and the end of screw rod is fixedly connected with limiting plate, the microswitch be electrically connected to controller is installed on described limiting plate, and described controller is electrically connected to motor, and the push rod of for pushing up, pressing microswitch is installed on described slider nut.
Further, described screw rodb base is fixed by spacer pin.
Further, described screw rod is hollow structure, is connected with power transmission shaft in it, and described power transmission shaft is connected with motor-driven.
Further, described power transmission shaft is hexagonal rod, itself and screw rod interference fit.
Beneficial effect of the present invention is, described electric-powered shutter is undertaken spacing by screw rod transmission with screw rod limiter, both guaranteed stability, greatly reduces again its cost, simple in structure, be easy to realize.
The accompanying drawing explanation
Fig. 1 is the structural representation of electric-powered shutter of the present invention with screw rod limiter.
In figure:
1, screw rod; 2, slider nut; 3, screw rodb base; 4, limiting plate; 5, push rod; 6, spacer pin.
The specific embodiment
Further illustrate technical scheme of the present invention below in conjunction with accompanying drawing and by the specific embodiment.
Please refer to shown in Fig. 1, Fig. 1 is the structural representation of electric-powered shutter of the present invention with screw rod limiter, in the present embodiment, a kind of electric-powered shutter screw rod limiter, comprise screw mandrel and be arranged on the screw rodb base 3 at screw mandrel two ends, described screw rodb base 3 is by spacer pin 6 fixed installations, described screw mandrel comprises screw rod 1 and is threaded in the slider nut 2 on screw rod 1, described screw rod 1 is hollow structure, be connected with power transmission shaft in it, described power transmission shaft is hexagonal rod, itself and screw rod 1 interference fit, and power transmission shaft is connected with motor-driven, the end of screw rod 1 is fixedly connected with limiting plate 4, the microswitch (drawing does not illustrate) be electrically connected to controller is installed on described limiting plate 4, described controller is electrically connected to motor, the push rod 5 of for pushing up, pressing microswitch is installed on described slider nut 2.
When the present invention installs, slider nut 2 need be selected relevant position according to the blind height of electric-powered shutter, during work, electric machine rotation drives power transmission shaft and rotates, thereby drive with the screw rod 1 of power transmission shaft interference fit, rotate, make slider nut 2 move on screw rod 1, when slider nut 2 moves to limiting plate 4 place of screw rod 1 end, push rod 5 on slider nut 2 is pressed onto the microswitch on limiting plate 4, thereby signal is passed to controller, controller is controlled motor and is decommissioned, and has played the effect of restriction blind stroke.
Although the end only illustrated in accompanying drawing 1 at screw rod 1 is equipped with limiting plate 4 and microswitch, the invention is not restricted to this, but screw rod 1 other end also mounting limit plate 4 and microswitch, thus stroke up and down spacing of realizing electric-powered shutter.
Above embodiment has just set forth basic principle of the present invention and characteristic; the present invention is not limited by above-described embodiment; without departing from the spirit and scope of the present invention, the present invention also has various variations and change, and these variations and change all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
