It is limited to receive space, and existing anti-reversing structure volume is bigger than normal, bad installation and debugging.
Utility model content
The purpose of this utility model is being to provide a kind of inner ratchet wheel type angular wheel mechanism of anti-reverse, and the mechanism is by ratchet
Pawl structures are integrated into angular wheel mechanism, realize anti-reverse rotating function, save space, small.
Technical solution used by the utility model is：
A kind of inner ratchet wheel type angular wheel mechanism of anti-reverse, including central shaft and two intermeshing angular wheels,
One of angular wheel endoporus is fixed with ratchet, and angular wheel and central shaft are coaxial where ratchet, ratchet, and central shaft is independent
Fixation is not connect with angular wheel and ratchet, and central shaft is equipped with the pawl coordinated with ratchet, and pawl can be around distortion simultaneously
It resets, ratchet can only one-directionally rotate under the action of pawl.
Further, pawl one end be the sharp hook coordinated with ratchet, the other end set on center shaft, pawl is sleeved on central shaft
Part be equipped at least two around the uniformly distributed arc key in axle center, central shaft is equipped with and the one-to-one arc groove of arc key, arc
The support of shape key is placed in arc groove and there are offset by gap, and the high other end in arc key one end is low, and spring, bullet are equipped in arc groove
Spring applies thrust to arc key low side always.
Further, pawl is sleeved on the part of central shaft and is additionally provided at least two around the uniformly distributed common key in axle center, central shaft
Be equipped with the one-to-one regular troughs of common key, common key support is placed in regular troughs and there are offset by gap.
Further, ratchet and the angular wheel at place are integrally formed.
The utility model has the beneficial effects that：
By click structure fusion into angular wheel mechanism, can only Unidirectional, realize anti-reverse rotating function, ratchet
It is fixed in angular wheel endoporus, saves space, it is small, it is suitable for low speed and the requirement to prevent reverses such as elevator, transveyer
Mechanically.

Specific implementation mode
The utility model is further described with reference to the accompanying drawings and examples.
As shown in Figure 1 to Figure 3, the inner ratchet wheel type angular wheel mechanism of a kind of anti-reverse, including central shaft 5 and two are mutually
The angular wheel (1# angular wheels 1 and 2# angular wheels 2) of engagement, 2 endoporus of 2# angular wheels is fixed with ratchet 3, ratchet 3,2#
Angular wheel 2 and central shaft 5 are coaxial, and individually fixation is not connect central shaft 5 with angular wheel (1 and 2) and ratchet 3, central shaft 5
It is equipped with the pawl 4 coordinated with ratchet 3, pawl 4 can deviate and reset around central shaft 5, and ratchet 3 can only under the action of pawl 4
One-directional rotation.By click structure fusion into angular wheel mechanism, can only Unidirectional, realize anti-reverse rotating function, spine
Wheel 3 is fixed in 2 endoporus of 2# angular wheels, saves space, small, is suitable for the low speed such as elevator, transveyer and is required anti-
Non-return turn mechanically.
As shown in Figures 3 to 5, in the present embodiment, 4 one end of pawl is the sharp hook 4-1 coordinated with ratchet 3, another end cap
On central shaft 5, the part that pawl 4 is sleeved on central shaft is equipped at least two on the uniformly distributed arc key 4-3 in axle center, central shaft 5
It is placed in arc groove 5-2 and exists between offset equipped with being supported with the one-to-one arc groove 5-2 of arc key 4-3, arc key 4-3
Gap, the high other end in the one end arc key 4-3 is low, and spring is equipped in arc groove 5-2, and spring always pushes away the application of -3 low side of arc key
Power.When ratchet 3 rotates forward, the sharp hook 4-1 of pawl 4 is slided on ratchet 3 and is slided to eminence by hook tooth lower, pawl 4
Arc key 4-3 is deviated to low side by spring compression from high-end, and when ratchet 3 rotates backward, the sharp hook 4-1 of pawl 4 is in hook tooth
Lower stopped by next hook tooth, at this time spring reset.The effect that arc key 4-3 high low sides are set be realize pawl 4 by
The offset when active force of ratchet 3 so that ratchet 3 can maintain to rotate forward.The effect that spring is arranged is to reset pawl 4, pawl 4
The unexpected prevention counterclockwise of ratchet 3 can be ensured by resetting.
As shown in Figures 3 to 5, in the present embodiment, pawl 4 is sleeved on the part of central shaft and is additionally provided at least two around axle center
Uniformly distributed common key 4-2, central shaft 5 is equipped with to be placed with the one-to-one regular troughs 5-1 of common key 4-2, common key 4-2 supports
In regular troughs 5-1 and there are offset by gap.Common key 4-2 main stabilizations act on, and prevent from sending out between pawl 4 and central shaft 5
Raw deflection up and down.
As depicted in figs. 1 and 2, in the present embodiment, ratchet 3 is integrally formed with 2# angular wheels 2.
