Abstract
The utility model provides a torsion spring return device. A tubular machine seat is arranged in a winding drum, one end of the tubular machine seat is fixedly connected with external equipment, and a planet gear speed-reducing machine is arranged in the other end; the low-speed end of the planet gear speed-reducing machine is arranged in the tubular machine seat by a torsion spring, and the high-speed end is fixedly connected with the winding drum by a driving wheel. When the winding drum rotates under the action of an external force, the stroke and rotating cycles are reduced through the driving wheel, the high-speed end, the speed-reducing machine to the low-speed end, and a torsion force is stored on the torsion spring after being amplified; when the external force on the winding drum disappears, the torsion force stored on the torsion spring is released, and the winding drum is driven to rotate at high speed in the opposite direction through the low-speed end, the speed-reducing machine, the high-speed end to the driving wheel, thereby achieving the purposes of prolonging the stroke without increasing the length of the torsion spring and realizing the return of more rotating cycles.
Description
Technical field
The utility model relates to the device that a kind of scrolling equipment resets with torsion spring, especially when the torsion spring resetting means that scrolling length (number of turns) increases, return stroke need prolong.
Background technique
At present, a lot of scrolling equipment are as volume Lian Men, and automobile-used window is honest and clean, and advertisement machine etc. are all directly installed torsion spring one end and are connected with reel in reel, and the mode that the other end is fixedlyed connected with external equipment resets.The door that its defective is rolled up is honest and clean, window is honest and clean, especially advertisement picture very long, when its width is subjected to certain restriction again and the length of torsion spring can't increase, thereby cause it to use.
Summary of the invention
Existing torsion spring reset mode is honest and clean when the door of being rolled up, window is honest and clean in order to overcome, especially very long, the defective when can't use by its width limitations again of advertisement picture, the utility model provides a kind of torsion spring resetting means, this device can prolong by the length of Roll Sushi and width unrestricted, and volume is little, in light weight, easy for installation.
The technological scheme that its technical problem that solves the utility model adopts is: a tubular shape support is installed in reel, the one end is fixedlyed connected with external equipment, a planetary gear speed-changing machine is installed in the other end, its low speed end is installed in the tubular shape support by torsion spring, and speed end fixes with reel by driving wheel and is connected.When turning round under the effect of reel in external force, by driving wheel, speed end, variable-speed motor to low speed end stroke and rotating cycle are diminished, be stored on the torsion spring after torsion is exaggerated, when the external force on the cylinder disappears, the torsion that is stored on the torsion spring discharges, oppositely run up by low speed end, variable-speed motor, speed end to drive wheel reel, reached the length that need not to increase torsion spring stroke is prolonged, the order ground that resets that rotating cycle is many.
The beneficial effects of the utility model are, can prolong by the length of Roll Sushi and width is unrestricted and volume is little, in light weight, easy for installation.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model embodiment central fore-and-aft vertical plane local structure figure.
Fig. 2 is that the utility model is executed left apparent structure figure in the example.
Among the figure 1, tubular shape support, 2. reel, 3, variable-speed motor, 4, driving wheel, 5, speed end, 6, low speed end, 7, torsion spring
Embodiment
