Description

Blind motor stroke control mechanism

Technical field

The utility model relates to a kind of stroke adjusting device, particularly a kind of blind motor stroke control mechanism.

Background technology

Existing blind motor stroke control mechanism includes the adjusting of upper and lower two groups of strokes, one group that promptly is conditioned often in adjustment process is being rotated, and the unadjusted frictional force that still need overcome between stroke adjustment wheel and stroke gear of organizing separately is gyrating, and is higher to the requirement on machining accuracy of part like this.

Summary of the invention

Technical problem to be solved in the utility model is: a kind of blind motor stroke control mechanism is provided, original stroke control mechanism is improved, when going up (descending) stroke adjustment, organize separately down (on) stroke control mechanism throws off and not rotate, not only reduced friction resistance and noise but also can reduce the machining accuracy of part.

The utility model addresses the above problem the scheme that is adopted: blind motor stroke control mechanism, comprise by connecting cogged output shaft and being connected with motor, be installed on switch enclosure and the gear box, switch enclosure, also be equipped with on the gear box by button, spring, the pushbutton unit that push-button socket constitutes cooperates with the stroke wheel support, switch that connects on the switch enclosure and fork, the stroke wheel support cooperates, the adjusting device of installing on the stroke wheel support be connected with duplicate gear form, the two sides of described stroke wheel support be installed in switch enclosure on, on the following two sides, end face is installed in two positive places of switch enclosure, bottom surface is installed in the switch enclosure kerve, and described adjusting device is the tooth on stroke adjustment wheel and the stroke gear that is installed on the stroke wheel support, the integral body that groove connects into constitutes.

Compared with prior art, advantage of the present utility model is: the structure of original blind motor stroke control mechanism is complicated, and adopt frictional drive between wheel of the stroke adjustment in the governor motion and stroke gear, when regulate one group go up (descend) stroke the time, another group following (on) stroke control mechanism also needs overcome friction to be rotated further.This part processing precision is had relatively high expectations simultaneously, and this mechanism improves original structure, during adjusting, needs to organize separately governor motion elder generation disengaging output shaft and does not work, and then this group governor motion is regulated.In addition stroke adjustment wheel is connected the structure that is improved to by tooth, groove connection, cooperation with friction between the stroke gear, make between two driving parts and can float, centering, can not kill, not only reduced frictional resistance and noise sound, can reduce requirement simultaneously part processing precision.

Below in conjunction with accompanying drawing embodiment of the present utility model is further described.

Upper and lower two groups of stroke control mechanisms are arranged.

Stroke gear

11,12 and 25,26 is two groups of gears of identical in structure, and an end is a gear, and end has

tooth

31,33, the

groove

32,34 of uniform protrusion in addition.

Stroke adjustment wheel

9,10 and 23,24 is two groups of stroke adjustment wheels of identical in structure, there is breach 9-1,10-1,23-1, the 24-1 that cooperates with fork switch 7-1,21-1 at the wheel edge, porose in the middle of the wheel, there are groove, tooth uniform and the corresponding cooperation of stroke gear in the limit, hole.

The two sides 5-2 (19-2) of stroke wheel support 5 (19) is installed on the upper and lower two sides 1-3 (19-3) of switch enclosure 1 (15), 5-3 (19-3) end face is installed in 1-4 (19-4) and locates, spring 8 (22) one ends are installed on the 5-4 (19-4), end is installed in the switch enclosure kerve 1-5 (19-5) in addition, stroke wheel support 5 (19) is upper and lower mobile in kerve 1-5 (19-5) under the effect of button 2 (16), as shown in Figure 1 and Figure 2.

Stroke wheel support 19 identical with stroke wheel support 5 structures (figure omits).

Stroke adjustment wheel 9 (23), 10 (24) endoporus is fixedly mounted on stroke gear 12 (26) respectively, on 11 (25), the endoporus of stroke gear 11 (25) is installed on the stroke gear 12 (26), with stroke gear 12 (26) external diameters be matched in clearance, two stroke gears 11 (25), can relatively rotate between 12 (26), stroke adjustment wheel 9 (23) rotates with stroke gear 12 (26), stroke adjustment wheel 10 (24) rotates with planetary gear 11 (25), one end of duplicate gear 13 (27) and gear 14 (28) engagements, hold and stroke gear 11 (25) in addition, 12 (26) engagements simultaneously, gear 14 (28) is fixed on switch enclosure 15, on the centre bore of tooth case 29, output shaft 30 passes gear 14 (28) endoporus simultaneously and is connected with gear box 29.

Stroke adjustment wheel 9 (23), 10 (24), stroke gear 11 (25), 12 (26) is installed in respectively on the stroke wheel support 5 (19) successively.

Spring 3 (17) is enclosed within on the axle of button 2 (16), button 2 (16) is installed in the push-button socket 4 (18), be embedded in the groove on the push-button socket 4-1 (18-1) with the seam 2-2 (16-2) on it, push-button socket 4 (18) is installed in the endoporus of stroke wheel support 5 (19), switch 6 (20) is installed on the two cylinder 1-1 (15-1) on switch enclosure 1 (15) end face, fork 7 (21) is installed on the cylinder 1-2 (15-2) on switch enclosure 1 (15) end face, and button 2,16 is installed in respectively in the through hole on switch enclosure 15, gear box 29 end faces.

During use, with the outside connected switch energized motor is rotated earlier, motor steering is controlled by external power supply.

If need to regulate up stroke, the output shaft 30 that needs earlier the stroke in the down stroke to be out of gear does not rotate it, regulate the up stroke desired position again, promptly press the button 16 earlier, promote to move down by button with its stroke wheel support 19 that links together, when stroke wheel support 19 moves down, corner 19-1 on it touches switch 20 closes it, connect motor 35 and drive output shaft 30 rotations by gear box 29, output shaft 30 driven

gears

14,28 rotate,

gear

14,28 drive duplicate gear 13 again respectively, 27 rotate, when stroke wheel support 19 moves down, be assemblied in the stroke gear 25 on the

stroke wheel support

19,26 also move down simultaneously, and

stroke gear

25,26 break away from duplicate gear 27, and promptly the

stroke gear

25,26 can not rotate, then connected

stroke adjustment wheel

23,24 can not rotate yet, that group governor motion that promptly at this moment will need not regulate is thrown off does not rotate it, organizes the adjusting of governor motion again separately.

At this moment duplicate gear 13 simultaneously and

stroke gear

11,12 engagements, duplicate gear 13 just drives stroke gear 11 simultaneously, 12 rotate, so because of number of teeth difference rotating speed also difference, stroke adjustment wheel 9 by its drive, 10 rotating speed is also different, but the breach 9-1 when original position on it, 10-1 and fork switch 7-1 are at same position, be that fork contact chip 7-2 and shift knob 6-1 are at disengaged position, switch 6 is in off-state, because of

stroke adjustment wheel

9,10 with after the different rotating speeds rotation, breach 9-1 on it, 10-1 is dislocation just, make fork switch 7-1 break away from breach 9-1,10-1 and sliding at stroke regulating wheel 9, on 10 the face of cylinder, contact chip 7-2 on fork 7 rotates an angle, just close a switch 6 when touching shift knob 6-1, connect motor 35 motor backward rotation, pin 16 a period of times of button (descends) operation to be adjusted to desired location on the blind that is installed on the motor output shaft so always, breach 9-1 on the stroke adjustment wheel, 10-1 just dislocation rotates corresponding angle, but at this moment with regard to release button 16 cut-off switch 20, at spring 17, under 22 the effect, button 16, stroke wheel support 19 is just got back to original position.

If need to regulate down stroke, at this moment can press button 2 descends stroke wheel support 5, need earlier the stroke gear in the up

stroke

11,12 to be thrown off it is not rotated, regulate down stroke again, detailed process is same as described above, at this moment closed motors 35 of connecting of switch 20, the blind on the motor output shaft just can descend (on) move and be adjusted to desired location.
