Detailed description of the invention
With embodiment, this utility model is described in further detail below in conjunction with the accompanying drawings, but enforcement of the present utility model
Mode is not limited to that.
As shown in Figure 1, Figure 2 and Figure 3, stop signpost power output switching device, including motor 1 and attaching case 2, described
Attaching case 2 includes the upper box 3 in the face of being fixed together and lower box 4, and upper box 3 is provided with and is connected to the defeated of stop signpost
Shaft 5, also includes damping clutch transmission, and described damping clutch transmission includes being provided with the rotating shaft 6 of screw thread 15, the company of fixing
Be connected in rotating shaft 6 six grades of gears 10, the Pyatyi gear 11 being socketed in relative rotation in rotating shaft 6, resilient urging force part 8,
Nut sleeve 9, impeller 7 and the damping fin 12 matched with screw thread 15 in rotating shaft 6, described rotating shaft 6 pack into successively Pyatyi gear 11,
Damping fin 12, impeller 7, latch 16, resilient urging force 8 and nut sleeve 9, the preferred spring of resilient urging force part 8, described Pyatyi
Being provided with the damping slot 24 that can place damping fin 12 inside gear 11, rotating shaft 6 is additionally provided with latch adjustable port 13, described latch 16 is inserted
Enter the latch circular hole 14 that impeller 7 is provided with, utilize its own resilient of spring to promote impeller 7, when impeller 7 pushes damping fin
12 to Pyatyi gear 11 time, latch 16 is further inserted into latch adjustable port 13 by latch circular hole 14, and squeezed air-damping sheet 12 pastes
Damping slot 24 on tight Pyatyi gear 11, such damping fin 12 makes rotating shaft 6 damp with Pyatyi gear 11 generation, as required, can
By the intensity of nut sleeve 9 with the screw extrusion spring of rotating shaft 6 screw thread 15, carry out damping adjusting size.
Stop signpost power output switching device also includes seven grades of gears 22 of coaxial affixed output shaft, coaxial affixed electricity
The one-level worm screw 17 of machine 1 power output shaft, the most affixed worm gear 18 and secondary gear 19, the most affixed tertiary gear 20 and
Level Four gear 21, described worm gear 18 and one-level worm screw 17 engage, and secondary gear 19 and tertiary gear 20 engage, level Four gear 21 He
Pyatyi gear 11 engages, and six grades of gears 10 and seven grades of gears 22 engage, and described Pyatyi gear 11 and six grades of gears 10 are provided with rotation
Sheet 23.
Operation principle of the present utility model is as follows:
When motor 1 rotates, the line shaft of motor 1 drives worm gear 18 to rotate by one-level worm screw 17, coaxial with worm gear 18
Affixed secondary gear 19 drives tertiary gear 20 to rotate, and the level Four gear 21 the most affixed with tertiary gear 20 drives Pyatyi tooth
Wheel 11 rotation, owing to rotating shaft 6 produces damping action with Pyatyi gear 11 by spring, now rotating shaft 6 is in Pyatyi gear 11
The state of fastening, Pyatyi gear 11 can drive rotating shaft 6 to rotate, and drives six grades of gears 10 to rotate, and drives seven grades of gears 22 to rotate,
Output shaft 5 is driven to rotate.
When output shaft 5 is by less external force, then the power that turns of rotating shaft 6 is less than between spring squeezed air-damping sheet 12 and Pyatyi gear 11
Damping, now rotating shaft 6 cannot rotate, thus avoid output shaft 5 counteracting force is returned gear mechanism cause gear mechanism and
The damage of motor 1；When output shaft 5 is by bigger external force, and such as user's palm, then the power that turns of rotating shaft 6 is more than spring squeezed air-damping sheet 12
And the damping between Pyatyi gear 11, now Pyatyi gear 11 and rotating shaft 6 presents slipping state, and rotating shaft 6 is dallied, output shaft 5
Counteracting force is dissolved because of the idle running of rotating shaft 6 at damping clutch transmission, thus avoids gear mechanism and the damage of motor 1.
Among first embodiment: described rotating shaft 6 is provided with latch adjustable port 13, described latch 16 injects and sets on impeller 7
Some latch circular holes 14, utilize its own resilient of spring to promote impeller 7, when impeller 7 pushes damping fin 12 to Pyatyi gear
When 11, latch 16 is further inserted into latch adjustable port 13 by latch circular hole 14, and squeezed air-damping sheet 12 is adjacent to Pyatyi gear 11
On damping slot 24, such damping fin 12 makes rotating shaft 6 produce damping with Pyatyi gear 11.
Second embodiment
It is with first embodiment difference: refer to Fig. 4 and Fig. 5, and described rotating shaft 6 is provided with track groove 25, institute
Stating impeller 7 and be provided with the parallel track face 26 matched with track groove 25, the parallel track face 26 of impeller 7 is along in rotating shaft 6
Track groove 25 promote the parallel Pyatyi gear 11 that is pressed down against of damping fin 12, squeezed air-damping sheet 12 is adjacent on Pyatyi gear 11
Damping slot 24, such damping fin 12 makes rotating shaft 6 produce damping with Pyatyi gear 11.
Being more than this utility model preferred forms, the simple change of those ordinary skill in the art and replacement are all
Within being protection domain of the present utility model.
