Abstract

The utility model discloses an automatic curtain traction system consisting of a curtain opening and closing power mechanism, a control mechanism and a power supply mechanism. The utility model is formed as follows: a connecting pipe on a belt, a limit clutch, a directional switch are used to control the rotation, the stop and the direction change of a DC motor to open and close the curtain. By a voltage comparator circuit and a relay, a standby battery pack is plunged into the system during power off, which improves the reliability of the operation of the utility model.

Description

The automatic curtain trailer system

Affiliated technical field

The utility model relates to automatic control curtain technical field, particularly a kind ofly draws the automatic curtain trailer system that curtain draws back automatically and closes.

Background technology

As everyone knows, time-consuming, the effort of curtain is drawn back and is closed in manually-operated,, children old to some and particularly inconvenience of disability crowd.Though occurred automatic curtain at present, but still had following defective: special pelmet or the curtain rod arm installed of needs when using automatic curtain is not easy to directly reequip original curtain, and can't uses when outage.For example existing patent CL 02154670.3, CL 200520090414.4.

Summary of the invention

Technical problem to be solved in the utility model: overcome the deficiency in the existing automatic curtain technology, propose a kind of simple in structure, easy to operate, automatic curtain trailer system easy, with low cost be installed solved the problems referred to above.

The technical solution adopted in the utility model: (1) curtain opens and closes actuating unit, and in order to the power of curtain bidirectional-movement to be provided, it comprises direct current generator, electric machine support, belt, pulley; (2) controlling organization in order to control the motor rotation, stop and changing its rotation direction, comprises that choosing is to switch, spacing clutch, belt tube connector; (3) power supply feed mechanism in order to the electric energy that provides motor to rotate, comprises AC, outage stand-by circuit.

The beneficial effects of the utility model: native system can directly be installed on original curtain, drops into stand-by power supply during outage to guarantee operate as normal.And can be used for the multiple occasion of automatic shutter of motion picture screen, the wall hanging picture door curtain made of cloth, good market prospects are arranged.

Specific embodiments

Known by Fig. 1: the power supply feed mechanism is supplied with direct current generator [1] with DC voltage, and driven by motor belt [3] rotates, the tube connector on the belt [4] traction curtain slip ring [10] moving linearly, the automatic open and close of realization curtain [5].Traction connecting ring [9] only needs to link to each other with the slip ring of the limit of curtain end and gets final product.

Known by Fig. 2, Fig. 3, Fig. 4: mobile chute [14] is arranged on the bracket base body [11], and bolt of fixing plate [13] can move interior, realizes that the distance between motor traction rotating disk [26] and the metope is adjusted.

Know by Fig. 5: be with belt [3] on direct current generator [1] and the fixed block [2], tube connector [4] is housed on the belt.Be elected to switch [27] and dial on one side, motor rotates counterclockwise, the curtain closure, and tube connector [4] backs down clutch [6], and circuit disconnects, the motor stall, clutch this moment [7] closes; Option switches is dialled to another side, and motor clockwise rotates, and curtain is opened, and tube connector backs down clutch [7], and circuit disconnects, the motor stall, and clutch this moment [6] closes.Can clutch be installed to adjust spacing distance according to actual conditions.

Known by Fig. 6: direct current generator [1] drives driving gear [24] and rotates, and output torque is passed to driven gear [25], rotates thereby drive traction wheel disc [26].Reduce output speed like this, improved the load capacity of motor.

Known by Fig. 7: tube connector constitutes belt tube connector body [15] by metal, on be connected with the tube connector collar [16].Thereby tube connector is compressed by the pressure pipe pincers and connects belt.

Known by Fig. 8, Fig. 9: spacing clutch [6] [7] is fixed on the wall by clutch-pedal support [17], and the clutch-plate [18] of two insulator compositions has arc groove [23]

Known by Figure 10: choosing pushes both sides respectively to switch [27] can make direct current generator [1] that different turning to arranged, and cooperates spacing clutch [6] [7] to realize the rotation and the stall of motor.

Know by Figure 11: produce stable VD after industrial-frequency alternating current process transformation, rectification, filtering, the voltage stabilizing, work as V ₀Be lower than minimum requirements voltage V _MinThe time (for example outage), operational amplifier A 2 is output as height, BJT T4 conducting, relay [30] work, its normal [29] closure of making war, battery backup [28] is devoted oneself to work.

AC/DC converting circuit part among the above-mentioned Figure 11 also ac/dc conversion electric power of available outsourcing replaces, and the choosing among Figure 10 replaces to the also available remote control switch of switch.If two piece curtain are then added one group of curtain trailer system and are got final product.
