Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is further described.
A kind of side-pull type tube shaped electric machine external-open, is made up of occlusion mechanism, gear mechanism and shell 1.Shell is formed by connecting by upper cover and end cover bolt.
Described occlusion mechanism comprises ratchet wheel 2 and ratchet 3 and torsion bar 8, and ratchet wheel is connected with the rotating shaft of built-in motor, and the head 31 of ratchet and ratchet wheel coordinate, and ratchet is arranged in ratchet rotating shaft 32, and is provided with torsion spring under ratchet, and the afterbody of ratchet is provided with roller 33.Slide block side of matching with ratchet, torsion bar is made up of an inclined-plane 44 and a vertical surface 45, and roller 33 and inclined-plane 44 match.
Torsion bar 8 rotating shaft is arranged on bottom, the upper ear 81 of torsion bar and the afterbody of ratchet contact, and the plane 45 on lower ear 82 and slide block matches, and the rotating shaft of torsion bar is provided with torsion spring 83, after the vertical surface 45 on the lower ear 82 and slide block of torsion bar leaves, torsion bar can rotate clockwise.
Described gear mechanism is made up of slide block 4, curve frid 5, baffle plate, spring 6, stay cord 7 and stay cord back-up ring.Stay cord back-up ring is arranged on shell, and baffle plate 11 is fixed between upper cover and bottom.Slide block side two pulleys 41 are installed, contacted with block 11 by pulley.The upper surface of slide block has chute 42, and the positioning block on this chute and upper casing coordinates, and makes slide block can only linearly to-and-fro motion.
The bottom surface of slide block 4 has a salient point 43, this salient point coordinates with curve frid 5.A curve frid bolt is arranged on shell 1, and rotates centered by bolt 55.Declutch because this is outer and allow side direction to install, so be provided with a damped ring 56 bottom the bolt hole of curve frid, and scribble butter 10 between curve frid 5 and shell 1.Under the acting in conjunction of damped ring and butter viscosity, the gravity of the adhesion of the external shell of curve frid and curve frid self offsets, and during the dress of curve frid side, can not drop, cause driving switch malfunctioning because of curve frid own wt.
