Description

The serving of electric rolling, distance caging device

Technical field

The present invention relates to the critical piece on a kind of electric rolling controller, particularly a kind of suitable and supporting blind automatic lifting, keying, the serving of withdraw from service electric rolling, distance caging device of making of blind.

Background technology

Development along with economic and scientific and technological cause, each city high rise building stands in great numbers, tree shade is embarked on journey, working environment, the condition of some units, enterprise, school are all improved greatly, office is not only spacious, window is many, window is bright greatly, daylighting is good, has also disposed the office facility of a lot of modernizations, automation.And the blind of reason manual operations, control is slow because of its operating rate, the needs of modern office chamber have been not suitable for, simultaneously manually blind do not match with the style and the layout of entire environment yet, inharmonious, the demand of can not satisfy the work of people's fast pace, study, living.

Number of patent application 200380104157.9 " manipulation device of hanging curtain " is though also provide a kind of manipulation device that can operate automatically, control hanging curtain, but it only has the function infinite place function of the rope of reeling, and the part in its manipulation device is more, assembling bothers.

The patent No. 02279802.1 " the coiling upper and lower position stop of curtain mechanism " only provides a kind of spacing mechanism of curtain opening that controls again.

Summary of the invention

Technical problem to be solved by this invention is: serving, distance caging device that a kind of electric rolling is provided, after its simple in structure, easy installation and electric controller are supporting, can use for the roller shutter of various different structures, its keying and stroke are operated, controlled to roller shutter automatically, and simple to operate, use more convenient.

The present invention addresses the above problem the technical scheme that is adopted: the serving of electric rolling, distance caging device are made of winding cylindrical shell that has rope and integral body that holder connects into, also include position-limit mechanism, described position-limit mechanism is cooperated by the spacer pin of fixing on spacer pin fixing on the screw rod and the guide wheel and forms; Described winding cylindrical shell is made up of guide wheel shaft that connects on screw rod and the screw rod and guide wheel, and described holder is made up of with the screw bracket that has compact heap the guide wheel that is connected on the screw rod.

Compared with prior art, the invention has the advantages that, upper and lower speed in the prior art during roller shutter differs greatly, decrease speed has a kind of sense of falling very soon, and this device can make the upper and lower speed difference of roller shutter few, move because of it upper and lower and all to drive screw rod by motor shaft and the transmission of guide wheel screw thread is carried out, it is wrapped in rope to have avoided on the guide wheel shaft phenomenon of the inhomogeneous or tangle up of rope backguy all the time regularly in addition.This guide wheel part both used as the part that twines on the cylindrical shell, its both ends of the surface seat that fixes again simultaneously uses, and on end face, be fixed with spacer pin and make stroke limit usefulness, have triple role, and original holder is assembled into by two parts and also only has fixing function.Screw bracket also directly is connected with screw rod for part independently, plays studdle and draws rope simultaneously and make the dual-use function that passage uses.Make full use of screw rod, guide wheel simultaneously, only fixedly mount the device that spacer pin has just constituted stroke limit thereon, omitted the fixed mount that stopping means is used, make a mechanism finish two functions.This apparatus parts is few, one part is used more, simple in structure, compact, volume-diminished half, easily assembling, reliable operation, can operate, control use with electric controller for roller shutter automatically after supporting, do not need manual operations, both improved the class of roller shutter, satisfied the life of people's fast pace, study, requirements of one's work simultaneously yet.

The specific embodiment

Below in conjunction with accompanying drawing embodiments of the invention are further described.

Screw rod 4 is cylindrical for the ladder that has line embedding groove 6, big end has gas thread, the centre is the hexagon blind hole, small end is on the shiny surface port wire casing to be arranged, screw rod 4 intermediate thread termination edges tightly are embedded with the spacer pin 13 of projection, line embedding groove 6 is embedded with another rope that is used to regulate and tangle blind sheet angle, as shown in Figure 4.

In the middle of the guide wheel 3 is tubular, two ends are the rectangle that open slot 15, through wires hole 14 are arranged, and one be through hole in the middle of the end, be screw in the middle of the end in addition, guide wheel 3 is enclosed within outside the

screw rod

4, and 2 sliding joining of an end through hole and guide wheel shaft, other holds being threaded of screw and screw rod 4, screw limit on the guide wheel 3 tightly is embedded with spacer pin 13 on spacer pin 12 and the screw rod 4 of projection mates and cooperates, as Fig. 5, shown in Figure 6.

Guide wheel shaft 2 is tubular, and an end of the mouth of pipe has inside projection and wire casing 16, as Fig. 7, shown in Figure 8.

Guide wheel shaft 2 and screw rod 4 are tightly fixed and are integral, in a termination through hole of guide wheel shaft 2, tightly be plugged with the end cap 1 of band unwrapping wire mouth, on the termination in addition of screw rod 4, be connected with the screw bracket 9 of band through wires hole 11, one end of rope 5 is passed in the wire casing 16 that the through wires hole 14 on the guide wheel introduces on the guide wheel shafts 2, and be fixed on the guide wheel shaft and be fixed in the screw rod 4 with end cap 1, rope 5 is wrapped on the surface of guide wheel shaft 2, end reaches outside the cord winder, by the through wires hole on the screw bracket 9 11 as shown in Figure 1 and Figure 2 in addition.

This device is installed in the curtain box 10 of blind upper end, utilize the projection of screw bracket 9 lower ends to be embedded in the through hole of curtain box 10 lower surfaces, and the open slot 15 on the guide wheel 3 cooperates with the slideway of curtain box two edges, upper surface at screw bracket 9 is screwed compact heap 8, and the open slot 17 on the compact heap 8 is cooperated with the slideway of curtain box 10 two edges, assurance screw bracket 9 is fixed and can not moved, as shown in Figure 3.

Motor shaft 7 is a tight fit in the hexagon blind hole of screw rod 4 one ends.

During use, open motor switch with remote controller, motor shaft 7 rotates and drives the rotation of screw rod 4 clockwise directions, then guide wheel shaft 2 outwards moves, rope 5 just constantly is wrapped on the guide wheel shaft 2, and blind is slowly scrolled up, when the screw on the guide wheel 3 is run into line embedding groove 6 on screw rod 4 edges, or else can rotate the effect of playing upper limit, as shown in Figure 1.

If will leave behind blind, as long as open motor switch with remote controller, motor shaft 7 drives screw rod 4 counter-clockwise direction and rotates, guide wheel shaft 2 counter-rotatings move inward, rope 5 is constantly emitted from guide wheel shaft, and blind is under the effect of self gravitation, and blind puts down with regard to moving down.Simultaneously screw rod 4 moves inward spacer pin 13 on it and runs into spacer pin 12 on the guide wheel 3, and at this moment screw rod can not rotate the effect of playing lower limit forward again, as shown in Figure 2.
