Abstract
The utility model discloses a screw rod limiter for an electric shutter. The screw rod limiter comprises a screw rod and screw rod bases arranged at the two ends of the screw rod. The screw rod comprises a screw and a sliding block nut connected to 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, the limiting plate is provided with a microswitch electrically connected with a controller, the controller is electrically connected with the motor, and the sliding block nut is provided with a push rod used for pushing and pressing the microswitch. According to the screw rod limiter, screw rod transmission is used for limitation, the stability is guaranteed and the manufacturing cost is greatly lowered. The screw rod limiter is simple in structure and easy to realize.
Description
Technical field
The utility model relates to a kind of electric-powered shutter screw rod limiter.
Background technology
Electric-powered shutter, has 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 adopting, and cost is higher, thus improved the cost of whole product, reduced its market competitiveness.
Utility model content
The purpose of this utility model is for the problems referred to above, and 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 purpose of this utility model 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 being electrically connected to controller is installed on described limiting plate, and described controller is electrically connected to motor, and the push rod of pressing microswitch for pushing up 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.
The beneficial effects of the utility model are, 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.
Accompanying drawing explanation
Fig. 1 is the structural representation of screw rod limiter for the utility model electric-powered shutter.
In figure:
1, screw rod; 2, slider nut; 3, screw rodb base; 4, limiting plate; 5, push rod; 6, spacer pin.
The specific embodiment
Below in conjunction with accompanying drawing and by the specific embodiment, further illustrate the technical solution of the utility model.
Please refer to shown in Fig. 1, Fig. 1 is the structural representation of screw rod limiter for the utility model electric-powered shutter, 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 fixedly mounts by spacer pin 6, 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, in it, be connected with power transmission shaft, 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) being electrically connected to controller is installed on described limiting plate 4, described controller is electrically connected to motor, the push rod 5 of pressing microswitch for pushing up is installed on described slider nut 2.
When the utility model is installed, 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 to rotate, thereby drive with the screw rod 1 of power transmission shaft interference fit, rotate, slider nut 2 is moved 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 only illustrated in accompanying drawing 1, in one end of screw rod 1, limiting plate 4 and microswitch have been installed, the utility model is not limited to this, screw rod 1 other end also can mounting limit plate 4 and microswitch, thereby realizes stroke up and down spacing of electric-powered shutter.
Above embodiment has just set forth basic principle of the present utility model and characteristic; the utility model is not limited by above-described embodiment; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various variations and change, and these variations and change all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
