Abstract
The utility model discloses an automatic curtain machine capable of preventing a rope and sheaves from slipping. The machine is provided with a main unit power mechanism and a curtain support mechanism, and the two mechanisms are independently assembled in a separating and closing manner in order to be convenient to mount. In the process of operation, the pull rope and the sheaves can never slip. In the curtain machine with any length, the stopping of a motor can be accurately controlled.
Description
Technical field
The utility model relates to a kind of automatic curtain machine
Background technology
At present, two kinds of automatic curtain machines are arranged on the market of China.(1) is a kind of single groove, the automatic window machine of single track dragline type, the design of this machine and embodiment, be at the two ends (left side) of window curtain driving mechanism track one single groove power block to be installed, (right side) installs the spiral planker pulley of a single groove, utilizes a stay cord that two pulleys are linked together.During work, spur cord for making pulley can drive stay cord work.Utilization (right side) limit screw rod is transferred the single groove pulley on the planker, the distance of two pulleys is separated, stay cord tension at this moment.Rope, wheel have just produced certain friction, spur cord.This embodiment, it can only use one very short period, and after several months, when the pulley polishing, stay cord elongates, and rope, wheel will lose friction, and at this moment stay cord just can't spur cord.(2) be a kind of belt-type window curtain driving mechanism, it is in order to solve rope, to take turns the new product that skids and occur, its embodiment is the round that utilizes on the belt, match with the tooth pitch on the gear, chain in machine spurs cord, it has solved the difficult problem that rope, wheel skid this mode, but a not only long but also heavy belt works in the track of a long distance back and forth, and it has increased the own loss of body.So it must lean on powerful motor to drive.In use, noise is big, is difficult to install.
More than, two kinds of window curtain driving mechanisms are not all installed the limit switch of motor, complete time-delay mode by circuit, dimensional standard because of the length neither one of window curtain driving mechanism regulation, so be difficult to control accurately electric machine spacing, since above several defectives, still a kind of cumbersome hand pulling type curtain that we use in our actual life.
The utility model content
The purpose of this utility model provides a kind of dragline type automatic curtain machine.(1) in the product of arbitrary length, utilize two knots on the stay cord and establish two limit switches of dress, when work, can accurately control the spacing work of motor.(2) in design, stay cord is to be fixed on the double flute power block, and when work, stay cord and pulley skid never.
The technical solution of the utility model is as follows: a kind of rope, the automatic curtain machine that wheel can not skid, it is relied on to levy and is that these facility have a stay cord (33) that has two knots, stay cord is fixed on the double flute power block (21), be connected on the Extension Spring-type planker pulley (28), utilize the pulling force of extension spring (30), pulling planker (29) tightly, make the single groove pulley (28) on the planker can be along with the degree of tightness of stay cord (33) is worked together back and forth in when work, stay cord just can freely falling body under any situation, and can remain on the parallel straight line, restrict during work, wheel skids never, in the course of the work, because of having, these facility aim at two electric machine spacing switches (14) (15) that motor is established dress, with a stay cord (33) that has two knots (34) (35), pass two shifters (24) (25), utilize two knots (34) (35) on the stay cord (33) can not be during work by the working method of shifter, drive two shifters (24) (25), promote two electric machine spacing switches (14) (15), can in the window curtain driving mechanism of arbitrary length, can both control motor accurately when driving cord work, make the cord switch to the artificial position of setting, under the electric machine spacing switch control of establishing dress, motor is stopped automatically.
But course of work root a tree name of the present utility model needs, in indoor any one position, and the transmitter in the operator, or press line traffic control and open, curtain will automatic switch.
Description of drawings
Figure (1) is a structure chart of the present utility model;
Figure (2) is the embodiment figure of the utility model double flute power block and the stay cord course of work;
Figure (3) is the utility model electric machine spacing process chart;
The specific embodiment
From figure (1) as can be seen, as a concrete frame mode of the present utility model, it its main frame actuation mechanism (1) one Curtain rod mechanism (2) is arranged for making in installation, two mechanisms adopt independently mode, clutch is assembled.Described main frame actuating unit, motor (11) receiver of remote-control sytem (12) electric capacity (13) is installed in the casing of main frame (1) simultaneously, and two electric machine spacing switches (14) (15) are installed in the shell upper of main frame (1) and form actuating unit (1).(21) two of described Curtain rod mechanism (left side) double flute power blocks are vertical to be decided (25) two springs of (23) two switch shifters of rope pulley (22) (24) (26) (27) and is installed in simultaneously in the main box (41).(right side) single groove pulley (28) one (29) extension springs of planker (30) are installed in the negative box in (42) simultaneously.Main box, negative box are installed in the two ends of two tracks (31) (32) simultaneously.A stay cord (33) that has two knots (34) (35) passes two shifters (24) (25) simultaneously and is fixed on the double flute power block (21), is connected on single groove pulley (28), forms Curtain rod mechanism (2).
The embodiment of the utility model double flute power block and the stay cord course of work
From figure (2) as can be seen, the specific embodiment of the utility model double flute power block and stay cord, during installation stay cord (33) is fixed on the double flute power block (21), is entangled in the A groove of double flute power block (21) with the whole long stay cord over half of window curtain driving mechanism.Link together with single groove pulley (28).When power block (21) rotated, stay cord (33) will move to a direction.Because of the curls inward of A groove has stay cord over half, so the diameter of A groove will be greater than B groove diameter.During work, A, B two grooves are to work asynchronously under a driven by motor, the pulling rope length that the pulling rope length that the B groove is involved in will be emitted less than the A groove.During work, stay cord will be by pine to tight, again by the working condition that is tightened to pine.In the stay cord pine, stay cord (33) will freely falling body, works for stay cord (33) can both be remained on the parallel lines at any time.This machine utilizes the pulling force of extension spring (30), and pulling planker (29) tightly can be worked the single groove pulley (28) on the planker together back and forth along with the degree of tightness of stay cord.Stay cord just can freely falling body, and rope, wheel just skid never during work.
The utility model electric machine spacing switching process
From figure (3) as can be seen, stay cord (33) is to pass from the pipeline of switch shifter (24) (25), two knots (34) (35) are arranged on the stay cord, when double flute power block (21) rotates, knot (34) on the stay cord (33) will be to the direction operation of shifter (24), knot (34) can not by shifter (24) at this moment knot (34) will drive shifter (24) pushing motor limit switch (15), electric machine spacing switch (15) is cut off the electricity supply, motor (11) quits work.When reverse connection power supply, double flute power block (21) reverse rotation, under the active force of spring (26), shifter (24) is got back to original position to knot (34) Off from shifter (24), and electric machine spacing switch (15) is connected again automatically.Simultaneously, knot (35) moves to the direction of shifter (25) again, knot (35) can not by shifter (25) at this moment knot (35) drive shifter (25) pushing motor limit switch (14) electric machine spacing switch (14) cut off the electricity supply, motor (11) quits work.
