Abstract
This utility model is related to a kind of locking device, specifically related to a kind of quick rotating locking apparatus, including rotating shaft, rotating shaft is built with sliding axle and bearing pin, slip outer shaft sleeve is equipped with base, sliding sleeve is set with outside base, along sliding axle diametrically cross sliding axle, base and sliding sleeve, sliding sleeve is provided with pilot hole obliquely to bearing pin.The device realizes that Small-angle Rotation is big apart from rotational lock, simple structure economy.
Description
Technical field
This utility model is related to a kind of locking device, and in particular to a kind of quick rotating locking apparatus.
Background technology
Rotational lock mechanism can all be used on many equipment at present, need locking function to be realized by adjustment angle, it is existing
Rotational lock be usually screw-type rotational lock, convert rotational motion into straight-line displacement and realize locking, big angle rotary is
Less straight line locking stroke can be realized, and straight line locking stroke distances are wayward, operation inconvenience, existing small angle rotation
The mechanism structure of big distance locking is complicated, expensive, not easy care.
Utility model content
According to deficiency of the prior art above, the technical problems to be solved in the utility model is：A kind of quick rotation is provided
Turn locking device, realize that Small-angle Rotation is big apart from rotational lock, simple structure economy.
Quick rotating locking apparatus described in the utility model, including rotating shaft, rotating shaft slide built with sliding axle and bearing pin
Outer shaft sleeve is equipped with base, and sliding sleeve is set with outside base, and bearing pin is along sliding axle diametrically cross sliding axle, base and sliding sleeve, sliding sleeve
It is provided with pilot hole obliquely.
During use, rotating shaft, sliding sleeve are rotated, and bearing pin is transverse in rotating shaft, and in the presence of pilot hole, sliding sleeve and bearing pin are present
With respect to upper and lower displacement, realize that Small-angle Rotation is big apart from rotational lock.
Preferably, bearing pin two ends are equipped with pad and back-up ring.
Preferably, rotating shaft upper end is provided with bumping post, facilitates rotating shaft.
Preferably, pilot hole obliquely is divided into upper and lower two tilting section, and lower tilting section angle of inclination is less than 5 °, upper inclination
Section angle of inclination is more than lower tilting section angle of inclination, and lower tilting section has auto-lock function.
This utility model is had an advantageous effect in that compared with prior art：
Quick rotating locking apparatus simple structure, it is big apart from rotational lock to realize Small-angle Rotation, is accurately controlled lock
Tight stroke, and there is auto-lock function, cost performance is high.

Fig. 2 is the expanded schematic diagram of sliding sleeve.
In figure：1st, rotating shaft；2nd, bumping post；3rd, base；4th, sliding axle；5th, back-up ring；6th, pad；7th, bearing pin；8th, sliding sleeve；9th, it is oriented to
Hole.
Specific embodiment
Below in conjunction with the accompanying drawings embodiment of the present utility model is described further：
As depicted in figs. 1 and 2, quick rotating locking apparatus include rotating shaft 1, and rotating shaft 1 is built with sliding axle 4 and bearing pin 7, sliding
Base 3 is set with outside moving axis 4, outside base 3, sliding sleeve 8 is set with, bearing pin 7 is along sliding axle 4 diametrically cross sliding axle 4, base 13
With sliding sleeve 8, sliding sleeve 8 is provided with pilot hole 9 obliquely.
7 two ends of bearing pin are equipped with pad 6 and back-up ring 5.
1 upper end of rotating shaft is provided with bumping post 2.
9 points of pilot hole obliquely is upper and lower two tilting section, and less than 5 °, upper tilting section is inclined at lower tilting section angle of inclination
Angle is more than lower tilting section angle of inclination, for example, stroke 12mm locking distances are realized under 110 ° of corners, and 30 ° of rotation passes through updip
Oblique section, big inclined-plane realize the locking stroke of 10mm, and by lower tilting section, 2mm locking strokes are realized on little inclined-plane to 80 ° of rotation residue,
2mm bevel angles are less than 5 °, prevent from unclamping after locking with auto-lock function.
During rotation, rotating shaft 1, sliding sleeve 8 are rotated, and bearing pin 7 is transverse in rotating shaft 1, and in the presence of pilot hole 9, bearing pin 7 is oblique
Relative upper and lower displacement in downward pilot hole 9, shift length are locking stroke during rotational lock, can pass through shaping-orientation
The parameter determination anglec of rotation and locking stroke in hole 9.
