Description
Technical field
The present invention relates to a kind of electric-powered shutter stopping means.
Background technology
Electric-powered shutter is to use a kind of curtain very widely, makes the shape of blinds, is subject to very much popular kind of curtain.The drive system of electric-powered shutter is comprised of motor, ropewinder and stopping means.The stopping means of existing electric-powered shutter, it exists cost high, and reaction is slow, and the problem of poor stability, is badly in need of solving.
Summary of the invention
The object of the invention is to for the problems referred to above, a kind of electric-powered shutter stopping means is provided, high with the stopping means cost to solve existing electric-powered shutter, reaction reaches the problem of poor stability slowly.
The objective of the invention is to be achieved through the following technical solutions:
A kind of electric-powered shutter stopping means, comprise upper beam, described upper beam is hollow structure, in it, be provided with for driving the motor of electric-powered shutter, described motor-driven is connected with transmission tube, removable and rotating being arranged in upper beam of described transmission tube, and be fixedly connected with limited block on transmission tube, be provided with gag lever post on described limited block, be fixedly connected with support on described upper beam, the lower end of described support is connected with the upper limit microswitch, and the upper end of support is connected with the lower limit microswitch, described upper limit microswitch and lower limit microswitch all are electrically connected to controller, described controller is electrically connected to motor, be positioned at lower limit microswitch left end on described support and be provided with the push rod of depressing position limited inching switch for top, be arranged with spring on described push rod.
Further, the output shaft of described motor is connected with power transmission shaft, described transmission tube is screw rod, it matches with the bolt in being fixed on upper beam, and transmission tube is hollow-core construction, be fixedly connected with inner sleeve in it, described inner sleeve is connected with transmission shaft bond, but and inner sleeve and power transmission shaft relative sliding.
Further, described inner sleeve and transmission tube interference fit.
Further, described gag lever post movably is arranged on limited block, and the end that gag lever post coordinates with push rod is provided with jacking block, and described jacking block is provided with certain radian.
Further, described gag lever post is threaded with limited block.
Beneficial effect of the present invention is that described a kind of electric-powered shutter is not only simple in structure with stopping means, is easy to realize, and cost is low, good stability, in addition, gag lever post movably is arranged on limited block, while deviation occurring, can be finely tuned, easy to operate, simple, and the jacking block of limited block one end is provided with certain radian, when transmission tube rotates, can throw off, be quick on the draw, fast.
The accompanying drawing explanation
Fig. 1 is the structural representation of a kind of electric-powered shutter of the present invention with stopping means.
In figure:
1, upper beam; 2, gag lever post; 3, jacking block; 4, push rod; 5, spring; 6, support; 7, upper limit microswitch; 8, lower limit microswitch; 9, limited block; 10, transmission tube; 11, bolt.
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 a kind of electric-powered shutter of the present invention with stopping means, in the present embodiment, a kind of electric-powered shutter stopping means, comprise upper beam 1, described upper beam 1 is hollow structure, in it, be provided with for driving the motor of electric-powered shutter, the output shaft of described motor is connected with power transmission shaft, described transmission tube 10 is screw rod, it matches with the bolt 11 in being fixed on upper beam 1, and transmission tube 10 is hollow-core construction, in it, interference fit has inner sleeve, described inner sleeve is connected with transmission shaft bond, but and inner sleeve and power transmission shaft relative sliding, be fixedly connected with limited block 9 on described transmission tube 10, limited location bar 2 is threaded on described limited block 9, the end that described gag lever post 2 coordinates with push rod 3 is provided with jacking block 4, described jacking block 4 is provided with certain radian, be fixedly connected with support 6 on described upper beam 1, the lower end of described support 6 is connected with upper limit microswitch 7, and the upper end of support 6 is connected with lower limit microswitch 8, described upper limit microswitch 7 and lower limit microswitch 8 all are electrically connected to controller, described controller is electrically connected to motor, be positioned at lower limit microswitch 8 left ends on described support 6 and be provided with the push rod 4 of depressing position limited inching switch 8 for top, be arranged with spring 5 on described push rod 4.
During work: the blind of driven by motor electric-powered shutter is up, when the blind of electric-powered shutter arrives the upper limit of stroke, the upper limit microswitch 7 of upper beam 1 lower end is encountered on top, and upper limit microswitch 7 passes to controller by signal, and controller is controlled motor and decommissioned, when the blind of driven by motor electric-powered shutter is descending, the driven by motor power transmission shaft rotates, power transmission shaft rotates and drives the inner sleeve rotation, thereby driving transmission tube 10 rotates, because transmission tube 10 is screw rod, it matches with the bolt 11 in being fixed on upper beam 1, but and inner sleeve and power transmission shaft relative sliding in transmission tube 10, when transmission tube 10 rotates, to right-hand member, move again, when the blind of electric-powered shutter arrives the lower limit of stroke, now the jacking block 3 of gag lever post 2 ends on limited block 9 just in time pushes up and encounters push rod 4, make push rod 4 tops encounter lower limit microswitch 8, lower limit microswitch 8 passes to controller by signal, controller is controlled motor and is decommissioned.
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.
