Abstract

The utility model relates to an electric rolling blind, wherein, an electric motor rotates to drive a reel to retract or put down cord fabric. A rolling blind bone is fixed on the lower edge of the cord fabric; stable slip rings which can slide on a stable slide way are arranged at two ends and the middle part of the rolling blind bone, thereby keeping stable. A longitudinal limit proximity switch is fixed on the stable slide way; the rolling blind bone is made of the material such as a steel bar, etc. which has certain weight and can lead the cord fabric to be flattened and sagged down. The rolling blind bone is adjacent to a normally-closed limit proximity switch; the normally-closed limit proximity switch switches off when inducing the approach of metal, and the electric motor is stalled to limit retracing or putting-down position of the rolling blind.

Description

With near the spacing electric rolling that steady slide rail is arranged of switch

Affiliated technical field

The utility model relates to a kind of roller shutter, the especially a kind of electric rolling that can use near switch qualification folding and unfolding position.

Background technology

The method that electric rolling commonly used at present limits the folding and unfolding position is a Stroke Control, resembles the journey controller that Chinese patent 03232015.9 is announced, the roller shutter motor that Chinese patent 00237135.9 is announced etc.These devices all are to use travel switch, microswitch to cooperate other parts to limit the position that roller shutter is packed up or decontroled, and the machine components that these stopping means use are more relatively, the structure more complicated, and integrated cost is higher relatively.More in addition, at present the common electric rolling cord of emitting is in free hang, does not stablize the device of cord, and wind loading rating is not strong under the outdoor application or the situation of windowing, and it is indefinite to drift when blowing, and result of use is not good.

Summary of the invention

Technical problem to be solved in the utility model is: provide a kind of using to limit the folding and unfolding position near switch, and simple in structure, to produce easy for installationly, integrated cost is lower, and stable windproof electric rolling.

The technical scheme that its technical problem that solves the utility model adopts is: the both sides at roller shutter are equipped with steady slide rail, can increase steady slide rail in the centre in case of necessity, steady slide rail can be made with materials such as rod iron or steel pipes, also can make with tough and tensile rope, steady slide rail cooperates with stable slip ring stablizes cord, strengthens wind loading rating.The roller shutter upper edge is fixed on the spool, and spool links to each other with motor output shaft, and motor rotate to drive spool and rotates, the relieving that realizes roller shutter with pack up.Be the position of restriction roller shutter folding and unfolding, on steady slide rail, fix normally closed near switch, when the metal curtain bone of roller shutter lower edge near near switch the time, close near inductive switching to metal, normally closedly disconnect near switch, the motor stall, roller shutter stops, and reaches spacing purpose.

The beneficial effects of the utility model are: the effect of stablizing slip ring and steady slide rail makes roller shutter stablize wind resistance; Spacing reliable and stable near switch, motor does not need stopping means, and the simple cost of technology is low.Whole roller shutter production is simple, easy for installation, good looking appearance, and integrated cost reduces.

The specific embodiment

Below in conjunction with the description of drawings specific embodiment of the present utility model: as shown in Figure 1, cord 1 upper edge is fixed on the spool 2, and motor 11 is installed in to be preserved in the tube 7, and spool 2 links with motor output shaft 10, motor 11 rotates and drives spool 2 rotations, and spool 2 rotates and can roll cord 1 or decontrol.A curtain bone 3 is fixed in the lower edge of cord 1, and there is the stable slip ring 5 that can slide curtain bone 3 two ends and centre on steady slide rail 4.Steady slide rail can be made with materials such as rod iron or steel pipes, also can make with tough and tensile rope.Curtain bone 3 uses materials such as rod iron, and certain weight is arranged, and can make cord 1 open and flat sagging.Steady slide rail 4 is fixed on the metope 9.The spacing upper and lower side that is installed in steady slide rail near

switch

15 and 16.

Motor 11 be can rotating alternating current generator, the 12,13, the 14th, its exit, when 12,13 were connected with power supply, motor just changeed, 13,14 when being connected with power supply, the motor counter-rotating.Spacing near switch the 15, the 16th, normally closed.Gauge

tap

17 and 18 can be a press button, also can be remote control switch.

Whole device is work like this, as shown in Figure 1 and Figure 2, in the time will decontroling roller shutter downwards, closure is transferred gauge tap 18, because lower limit is normally closed near switch 16, when metal curtain bone 3 is not close to lower limit near the distance of reaction of switch 16 downwards, lower limit is closed near switch 16, near switch 16 with transfer gauge tap 18 and power connection, motor just changes the exit 12 of motor, drives spool 2 and puts down roller shutter by lower limit.When metal curtain bone 3 was close to lower limit near the distance of reaction of switch 16 downwards, lower limit disconnected near switch 16, the motor stall, and roller shutter is limited to this position.Identical therewith, in the time will making progress roller shutter, volume gauge tap 17 on the closure, because upper limit is normally closed near switch 15, when metal curtain bone 3 upwards was not close to upper limit near the distance of reaction of switch 15, upper limit was closed near switch 15, the exit 14 of motor by upper limit near switch 15 and last volume gauge tap 17 and power connection, the motor counter-rotating drives spool 2 and rolls roller shutter.When metal curtain bone 3 upwards was close to upper limit near the distance of reaction of switch 15, upper limit disconnected near switch 15, the motor stall, and roller shutter is limited to this position.

Claims

1. electric rolling, comprise the spool that is fixed on the cord upper end, the curtain bone of cord lower end, curtain bone two ends and middle stable slip ring, and steady slide rail, with the motor that spool links, the gauge tap of motor is characterized in that: on the steady slide rail fixing limit that roller shutter is packed up or ejected position near switch.
