(2) the utility model is by employing half groove, when motor normally runs, make scotch be positioned at half groove, scotch does not contact motor shaft, thus can not affect motor and run, when needs stop, scotch is pushed in groove and utilize motor shaft rotator inertia to drive scotch to move in groove, utilize the change of spacing end thickness, the distance between scotch with motor shaft is reduced gradually and then phase mutual friction realization deceleration, structure is more simple, easy to operate.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme of the utility model embodiment, be briefly described to the accompanying drawing used required in embodiment below, be to be understood that, the following drawings illustrate only some embodiment of the present utility model, therefore the restriction to scope should be counted as, for those of ordinary skill in the art, under the prerequisite not paying creative work, other relevant accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is the utility model overall structure schematic diagram;
Fig. 2 is the utility model fixed muffle structural representation.
Wherein: 101. motor bodies, 102. motor shafts, 103. fixed muffles, 104. half grooves, 105. grooves, 106. scotchs, 107. antiskid grooves, 108. manual operation connecting rods.
Embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail, but execution mode of the present utility model is not limited thereto.
As shown in Figure 1, 2, a kind of motor, comprise motor body 101 and be arranged on the motor shaft 102 on motor body 101, fixed muffle 103 is set with outside described motor shaft 102, the internal diameter of described fixed muffle 103 is greater than the external diameter of described motor shaft 102, and described fixed muffle 103 one end is fixedly connected on the sidewall of described motor body 101;
Described fixed muffle 103 is provided with half groove 104, described half groove, 104 T-slots, half described groove 104 parallels with the axis of described fixed muffle 103, the sidewall of described fixed muffle 103 is provided with groove 105, described groove 105 is arranged along described fixed muffle 103 circumference, described groove 105 is connected with half described groove 104 one end, spacing end is formed at the fixed muffle 103 of described groove 105 near half described groove 104 side, described spacing end is greater than its thickness h near described half groove 104 near the thickness H at described groove 105 two ends,
In half described groove 104, be provided with scotch 106, the cross section of described scotch 106 is T-shaped, and described scotch 106 can slide along described groove 105 along described.
When motor stopping; motor shaft freely rotates under effect of inertia; now promote scotch; it is made to slide along half groove 104; when scotch slips in groove; scotch contacts with motor shaft near motor shaft one side end face; it is fitted in spacing tip inside away from motor shaft one side end face; because the thickness of spacing end to groove 105 two ends increases gradually; make the distance between scotch and motor shaft more and more less; and then the friction between scotch and motor shaft is increased gradually, realize the deceleration to motor shaft gradually.
Embodiment 1:
