Abstract
A locking mechanism comprises two upper connection boards, two lower connection boards, an inner pin shaft, an outer pin shaft, a rotating shaft and a small hook. The two upper connection boards are clamped between the two lower connection boards, the inner pin shaft only hinges one ends of the two upper connection boards arranged between the two lower connection boards together, and the outer pin shaft hinges one ends of the two lower connection boards and the middle portions of the two upper connection boards. The two upper connection boards can rotate around the outer pin shaft, the other ends of the two lower connection boards are hinged through the rotating shaft and fixed by the rotating shaft, and the whole mechanism can rotate around the rotating shaft through the two lower connection boards. The small hook comprises a semicircular hook portion and a straight portion, the straight portion of the small hook is fixed on an object needing locking, and the inner pin shaft is installed with the semicircular hook portion of the small hook in concentric mode. The locking mechanism has the advantages of being novel in design, reasonable in structure, small, handy, capable of meeting requirements of various vehicles and high in economic value added.
Description
Technical field
The present invention relates to automobile mechanical field, relate in particular to a kind of locking mechanism.
Background technique
At present on automobile, applied many locking devices, the large-scale vehicle body hydraulic lock that comprises, spare tyre hydraulic lock, but a lot of small-sized locking mechanism uses hydraulic lock, not only cost is higher, and it is large to take up room.
Summary of the invention
The present invention is for addressing this problem, and designed a kind of novel, rational in infrastructure, small volume and less weight, the demand that can meet various vehicles, locking mechanism that economic value added is high.
The present invention realizes by following technical measures: a kind of locking mechanism, comprises two upper junction plates, two lower connecting plates, interior bearing pin, outer bearing pin, turning axle, little hook; Described two upper junction plates are clipped in the centre of two lower connecting plates, interior bearing pin only by two upper junction plates the one end between two lower connecting plates hinged; Outer bearing pin is by hinged the middle part of one end that comprises two lower connecting plates of two lower connecting plates and two upper junction plates, and, two upper junction plates can rotate around outer bearing pin, the other end of two lower connecting plates is hinged by turning axle, described turning axle is fixed, and whole mechanism can rotate by two lower connecting plate wraparound rotating shafts; Described little hook comprises the hook portion of semicircle and straight part, the straight partial fixing of described little hook on the object of needs locking, the concentric installation of hook portion of interior bearing pin and little hook semicircle.
Concrete feature of the present invention also has, and the shape of above-mentioned upper junction plate and described lower connecting plate is identical.
One end of above-mentioned upper junction plate and described lower connecting plate is with bending part.
Above-mentioned interior bearing pin and described outer bearing pin two ends adopt and rush riveting.
Above-mentioned two upper junction plate the other ends relative with interior bearing pin are fixed with handle.
Beneficial effect of the present invention is: it has novel, rational in infrastructure, small volume and less weight, the demand that can be satisfied with various vehicles, economic value added high.
Accompanying drawing explanation
Fig. 1 is the structural representation of the specific embodiment of the invention.
Fig. 2 is the plan view of Fig. 1.
Fig. 3 is the structural representation of the specific embodiment of the invention while opening.
In figure, 1, upper junction plate, 2, outer bearing pin, 3, little hook, 4, lower connecting plate, 5, interior bearing pin, 6, handle, 7, turning axle, 8, the hook portion of semicircle, 9, straight part, 10, bending part.
Embodiment
For clearly demonstrating the technical characterstic of this programme, below by an embodiment, this programme is set forth.
As shown in drawings, a kind of locking mechanism, comprises two upper junction plates 1, two lower connecting plates 4, interior bearing pin 5, outer bearing pin 2, turning axle 7, little hook 3; Described two upper junction plates 1 are clipped in the centre of two lower connecting plates 4, interior bearing pin 5 only by two upper junction plates 1 one end between two lower connecting plates 4 hinged, two upper junction plate 1 the other ends relative with interior bearing pin 5 are fixed with handle 6.Outer bearing pin 2 is by hinged the middle part of one end that comprises two lower connecting plates 4 of two lower connecting plates 4 and two upper junction plates 1, and, two upper junction plates 1 can rotate around outer bearing pin 2, the other end of two lower connecting plates 4 is hinged by turning axle 7, described turning axle 7 is fixing, and whole mechanism can rotate by the 4 wraparound rotating shafts 7 of two lower connecting plates; Described little hook 3 comprises the hook portion 8 of semicircle and straight part 9, and the part 9 that described little hook is straight is fixed on the object that needs locking, the concentric installation of hook portion 8 of interior bearing pin 5 and little hook semicircle.
Wherein, upper junction plate 1 is identical with the shape of lower connecting plate 4, and one end of upper junction plate 1 and described lower connecting plate 4 is with bending part 10.Like this, can further save installing space and make again handle 6 gyration center and turning axle 7 gyration center have individual height difference, laborsaving and coupling mechanism force is large while moving.Interior bearing pin 5 and outer bearing pin 2 two ends all adopt and rush riveting.
A whole set of locking mechanism is divided into locking and opens two kinds of working staties, in during locking, bearing pin 5 is concentric with little hook 3, by little hook 3, stop generation coupling mechanism force, upper junction plate 1 and the straight part of lower connecting plate 4 must be parallel to the lower plane of the part 9 that little hook 3 is straight simultaneously, could produce so maximum coupling mechanism force, can not open voluntarily.While opening, be first that upper junction plate 1 upwards rotates around outer bearing pin 2, in driving, bearing pin 5 skids off in the hook portion 8 of the semicircle of little hook 3 simultaneously, and while being opened to several angle, whole mechanism upwards rotates around turning axle 7 again, thereby has opened whole locking mechanism.
The present invention can pass through or adopt existing techniques in realizing without the technical characteristics of describing; do not repeat them here; certainly; above-mentioned explanation is not limitation of the present invention; the present invention is also not limited in above-mentioned giving an example; variation, remodeling, interpolation or replacement that those skilled in the art make in essential scope of the present invention, also should belong to protection scope of the present invention.
