Description
Technical field
The present invention relates to a kind of mechanical self-locking mechanism, and in particular to the rotary spine applied to safety socket self-locking occasion
Tooth self-locking mechanism.
Background technology
In existing safety socket mechanical automatic locking mechanism, a kind of mechanical automatic locking mechanism more generally used, typically by tooth
Wheel combined with ratchet, alignment pin is provided with ratchet, alignment pin matches with ratchet, when gear march forward direction rotation
When, gear drives the pawl wheel being meshed with gear, and now ratchet stirs positioning finger setting, the mechanical self-latching machine of this structure
Structure is positioned by alignment pin completely, when needing to use gear counter-steering, it is necessary to be first turned in alignment pin, structure more
Complexity, self-locking and unblock operate it is relatively complicated, and lock it is unreliable, manufacturing cost is also higher.
The content of the invention
The present invention solves the technical problem of provide a kind of rotary ratchet self-locking mechanism, the rotary ratchet self-locking
Mechanism can reliably self-locking and unblock, it is simple in construction easy to operate.
To achieve the above object, the technical solution adopted by the present invention is：Rotary ratchet self-locking mechanism, including from top to bottom
It is arranged in rotating ratchet and fixed ratchet wheel on center shaft, the lower end circumference of the rotating ratchet and is provided with covert ratchet, institute
The guiding ratchet being provided with the upper end circumference of fixed ratchet wheel with the covert ratchet engagement is stated, the covert ratchet is with being oriented to spine
The field of conjugate action outer sheath of tooth is provided with inner circle ratchet.
In the above-mentioned technical solutions, the rotating ratchet is led including four equally distributed rotating ratchets that outer ring is set
Key, the rotating ratchet lead key lower end is the hollow ring that covert ratchet and inner ring are set.
In the above-mentioned technical solutions, the inner circle ratchet includes setting four guide grooves on a hollow ring, adjacent
Locking teeth and unblock tooth are disposed between two guide grooves.
In the above-mentioned technical solutions, the fixed ratchet wheel is set including four the equally distributed lead keys and inner ring that outer ring is set
The eight guiding ratchets put.
The rotary ratchet self-locking mechanism of the present invention is made up of the inner circle ratchet of rotating ratchet, fixed ratchet wheel, central shaft,
In the presence of external force, rotating ratchet, fixed ratchet wheel are discharged into use state upward or are locked in partially by inner circle ratchet
The dormant state of lower section, or mechanical self-latching is formed under external force, locking and self-locking reliability are high, and overall structure is simple, behaviour
Make easy, it is safe, it can be applicable to the various occasions for needing self-locking and unlocking.

Embodiment
The technical scheme in the embodiment of the present invention will be clearly and completely described below, it is clear that described implementation
Example is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, this area is common
All other embodiment that technical staff is obtained under the premise of creative work is not made, belongs to the model that the present invention is protected
Enclose.
Refer to the rotary ratchet self-locking mechanism shown in Fig. 1, including the rotation spine being set in from top to bottom on central shaft 1
Wheel 2 and fixed ratchet wheel 3, the lower end of rotating ratchet 2 are circumferentially provided with covert ratchet 2.2, and the upper end of fixed ratchet wheel 3 is circumferentially provided with
The guiding ratchet 3.2 engaged with covert ratchet 2.2, covert ratchet 2.2 is provided with inner circle with being oriented to the field of conjugate action outer sheath of ratchet 3.2
Ratchet 4.
Rotating ratchet 2 includes four equally distributed rotating ratchet lead keys 2.1 that outer ring is set, rotating ratchet lead key 2.1
Lower end is the hollow ring 2.3 that covert ratchet 2.2 and inner ring are set.Inner circle ratchet 4 includes setting four on a hollow ring
Locking teeth 4.1 and unblock tooth 4.2 are disposed between individual guide groove 4.3, two adjacent guide grooves 4.3.Fixed ratchet wheel 3 includes outer
Eight guiding ratchets 3.2 that four the equally distributed lead keys 3.1 and inner ring that circle is set are set.
The locking teeth 4.1 of the inner circle ratchet 4 of the present invention is locked by the outer end of covert ratchet 2.2 of rotary ratchet self-locking mechanism
When be in lockup state, during the unlocked position that external force effect is lower to reach rotary ratchet self-locking mechanism, the rotation spine of rotating ratchet 2
Wheel lead key 2.1 completely disengages from the constraint of the guide groove 4.3 of inner circle ratchet 4, and the covert ratchet 2.2 of rotating ratchet 2 is inner along rotary
Flank of tooth slid clockwise to the inner circle ratchet 4 of the guiding ratchet 3.2 of the fixed ratchet wheel 3 of ratchet self-locking mechanism is unlocking helical tooth flank just
Top.External force is now cancelled, the flank of tooth of unblock tooth 4.2 of inner circle ratchet 4 further makes above-mentioned rotating ratchet lead key 2.1 sliding clockwise
Guide groove 4.3 is moved up into, released state is converted to.
When the covert ratchet 2.2 of the rotating ratchet 2 of rotary ratchet self-locking mechanism is inner along rotary ratchet self-locking mechanism
Fixed ratchet wheel 3 guiding ratchet 3.2 flank of tooth slid clockwise to inner circle ratchet 4 the flank of tooth of locking teeth 4.1 directly over when, remove
Pressure is sold, the unblock flank of tooth of tooth 4.2 of inner circle ratchet 4 further makes the lead key up time of rotating ratchet lead key 2.1 of above-mentioned rotating ratchet 2
Pin sliding enters the root of locking teeth 4.1 of inner circle ratchet 4, now discharges pressure, inner circle ratchet 4 is by the covert spine of rotating ratchet 2
The outer end of tooth 2.2 is limited, therefore locked.Embodiments of the invention are the foregoing is only, the patent model of the present invention is not thereby limited
