Abstract
The utility model relates to an electric and hand operated clutch for a tubular motor, which is composed of gear wheels which are arranged in a left end cover and a right end cover of a cavity and a bracing cable which is respectively connected with a switch of the clutch and a converting mechanism, wherein the converting mechanism is composed of a gear rack, an eccentric wheel which is arranged in the cavity of the gear rack and is formed by the match of the gear rack and the gear wheels. The eccentric wheel is connected with a torsion spring and one end of the bracing cable, and the other end of the bracing cable is connected with the switch of the clutch by bypassing a guide wheel on a support frame. The eccentric wheel is arranged in the cavity of the gear rack not to occupy useful space, and the gear rack has double actions of a housing and a clutch gear rack. The utility model has the advantages of compact and reasonable structure, small size, convenient operation, time saving and safe and reliable use and the disconnection and the engagement of the gear wheels and the gear rack are achieved by raising and reducing the position of the gear rack as long as the eccentric wheel is driven to rotate an angle by the bracing cable so that the conversion of hand operation and electrical operation is achieved, the speed of the conversion of the hand operation and the electrical operation of a rolling door and a window is enheanced.
Description
Technical field
The utility model relates to a kind of clutch that uses on rolling door, window, just often driven the folding of rolling door, window by tube shaped electric machine, by manual operation rolling door, window opening and closing, is used to change electronic, the manual clutch of tube shaped electric machine of use during power failure.
Background technology
The patent No. 02265408.9 " a kind of tube shaped electric machine with arrangement of clutch " provides a kind of and has been meshing with each other by worm gear, worm screw, carry out manually operated arrangement of clutch and throw off when having a power failure, but its reset operation is trouble, needs to bring inconvenience through operation several times to the user.
The patent No. 200320120617.4 door opener of dual-use manual roller shutter door machine " electronic, " also provides a kind of and has been meshing with each other by two gears, during power failure, with wire rope one gear is drawn back, break away from the engagement of clutch gear and carry out manually operated door opener, but it is fast not enough that its spanner is pulled distance speed bigger, electronic, manual switch.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of tube shaped electric machine electronic, manual clutch, simpler, the easy making of its structure, volume are little, and easy to operate, can improve rolling door, electronic, the manual switch speed of window, and safe and reliable.
The technical scheme in the invention for solving the above technical problem is: tube shaped electric machine is electronic, manual clutch comprises and forming gear that is installed in the left and right end cap cavity and the drag-line that is connected with clutch switch and switching mechanism, described switching mechanism is by tooth bar and the eccentric wheel that is installed in the tooth bar cavity, and the rack and pinion cooperation is formed, also be connected with an end of torsion spring and drag-line on the described eccentric wheel, drag-line holds the guide wheel of walking around on the support to be connected with clutch switch in addition.
Compared with prior art, advantage of the present utility model is, the eccentric wheel of this clutch is mounted in the cavity of tooth bar, do not take the usefull space, and tooth bar has the double action of housing and clutch tooth bar, make its more compact structure, rationally, volume is little, only need to drive eccentric wheel and rotate an angle with drag-line, be used to raise, the disengagement and the engagement of wheel and rack realized in the position that reduces tooth bar, thereby reach manual, electronic conversion, tooth bar is the rectangular tubular that soffit has tooth, and drag-line just can make tooth bar upwards as long as the pulling eccentric wheel rotates, moving down a tooth depth distance just can throw off or contact, promptly improved rolling door, window is electronic, the speed of manual switch, saved the time again simultaneously, easy to operate, and safe in utilization, reliably.Bearing also is housed on the camshaft, the power of reducing friction, it moves flexibly, easily to make tooth bar.

The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
Tooth bar 4 is a rectangular tubular, and corresponding two kidney slots are arranged on the two sides, and the tooth with gear 3 engagements is arranged on the pipe soffit centre position.
The wire casing that arc concave is arranged on eccentric wheel 6 peripheries, an end of the fluted fixedly torsion spring 9 in side upper end, torsion spring 9 end in addition extends outside the eccentric wheel 6, and there is the right angle breach side lower end, and indentation, there has the screw 8 of stay guy 5.
Axle 12 passes tooth bar 4, eccentric wheel 6, and bearing 7 is equipped with at two ends, matches with kidney slot on the tooth bar 4, alleviate the upper and lower mobile frictional force of tooth bar, spindle nose is fixed on the left and right end cap, and left and right end cap 11,13 usefulness screws link into an integrated entity, and eccentric wheel 6 can rotate in tooth bar 4 cavitys.
One end of drag-line 5 is fixed on the eccentric wheel 6 with screw 8, embeds in eccentric wire casing, and other end is walked around guide wheel and is connected with clutch switch 10.
Gear 3 is installed in the left and right end cap cavity of tooth bar 4 lower ends.
The end that clutch is installed in tube shaped electric machine just can have been used.
If have a power failure, at this moment availablely pull drag-line 5 once and drive clutch switch, eccentric wheel 6 clockwise directions that link together with drag-line rotate, because of the eccentric wheel lower diameter greater than upper diameter, when eccentric wheel rotated, the tooth bar 4 that just will link into an integrated entity with it up pushed up, and was about to whole tooth bar and raised, make the tooth out-of-gear of tooth bar bottom, it is motionless that clutch switch rests on the extreme lower position drag-line.This moment, torsion spring tightened up, with regard to available manual operation, and the folding of control rolling door, window.
If need electronic, at this moment again with pulling moving drag-line 5 once, clutch switch just unclamps drag-line, eccentric wheel 6 counterclockwise rotates under the effect of torsion spring 9 power, up to the upper limit of clutch switch (patent application is arranged in addition) to setting, at this moment the eccentric wheel upper diameter is less than lower diameter, and eccentric wheel 6 is depressed tooth bar 4, electronicly transfers the folding that bonding state just can recover electric operating rolling door, window once starting tooth bar 4 to gear 3.
