Abstract
The utility model relates to a closing mechanism who pegs graft and lock, including the tapered end body and bayonet joint, assembly lock core axle and offered the spliced eye with bayonet joint matched with in the tapered end body is equipped with along with lock core axle pivoted hasp for the spliced eye position in the rear end of lock core axle, and the hasp forms minor face and long limit respectively on its two crossing faces, offered the lockhole in the bayonet joint, and the diameter of lockhole is greater than the length on long limit, and edge that the lockhole is relative with the hasp forms the opening, and the length that the open -ended width is greater than the minor face just is lighter than the length on long limit. The utility model overcomes the structure that ordinary grafting lock closing mechanism exists among the prior art is complicated comparatively, defect that manufacturing cost is high, and through above -mentioned detailed design, the lock of pegging graft when the minor face is relative with the opening can be opened, and the grafting is locked and is locked when long limit is relative with the opening, has that simple structure compactness, convenient assembling, manufacturing cost are hanged down, the advantage of good reliability.
Description
Technical field
The utility model relates to the switching mechanism of a kind of grafting lock.
Background technology
Existing grafting lock switching mechanism, all comprise tapered end and be assemblied in locking plate, the lock core in tapered end, be provided with lock latch jack in tapered end, lock core drives locking plate forward or reverse, locking plate is made to engage with the groove on lock bolt or be separated, thus the object reaching locking, unblank.Above-mentioned grafting lock switching mechanism, its its assembly structure is comparatively complicated, and cost of production is high.
Summary of the invention
Comparatively complicated in order to overcome the structure that in prior art, common grafting lock switching mechanism exists, the problem that cost of production is high, the switching mechanism that the utility model provides a kind of grafting to lock, this grafting lock switching mechanism simple and compact for structure, easy to assembly, cost of production is low, reliably sealed.
The utility model solves the technical scheme that its technical problem adopts: comprise tapered end and connection-peg, assemble lock core shaft in tapered end and offer the spliced eye matched with connection-peg, be provided with the lock bolt rotated with lock core shaft relative to spliced eye position in the rear end of lock core shaft, lock bolt forms minor face and long limit respectively on two faces that it intersects, lockhole is offered in connection-peg, the diameter of lockhole is greater than the length on long limit, the limit that lockhole is relative with lock bolt forms opening, and the width of opening is greater than the length of minor face and is less than the length on long limit.
Be provided with spacing elastic component at tapered end inner bottom part, be pressed on spacing elastic component bottom the two side ends of opening.
By spring and gland, the spring base on spring is formed spacing elastic component, and spring base is provided with the groove relative with opening, is pressed on the end face of groove both sides bottom the two side ends of opening.
The utility model is by above-mentioned specific design, and when minor face is relative with opening, grafting is locked and can be opened, and when long limit is relative with opening, grafting locks, and has simple and compact for structure, easy to assembly, that cost of production is low, reliability is strong advantage.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, detailed content of the present utility model is described.
Fig. 1 is decomposition texture schematic diagram of the present utility model.
Fig. 2 is the assembly structure schematic diagram of the utility model at lock-out state.
Fig. 3 is the assembly structure schematic diagram of the utility model at unlocking condition.
Fig. 4 is the assembly structure schematic diagram that in the utility model, connection-peg ejects state.
As shown in the figure, the utility model comprises tapered end 1 and connection-peg 2, assemble lock core shaft 3 in tapered end 1 and offer the spliced eye 4 matched with connection-peg 1, be provided with the lock bolt 5 rotated with lock core shaft 3 relative to spliced eye 4 position in the rear end of lock core shaft 3, lock bolt 5 forms minor face 5A and long limit 5B respectively on two faces that it intersects, lockhole 6 is offered in connection-peg 2, the diameter of lockhole 6 is greater than the length of long limit 5B, the limit that lockhole 6 is relative with lock bolt 5 forms opening 7, and the width of opening 7 is greater than the length of minor face 5A and is less than the length of long limit 5B.Spacing elastic component 8 is provided with at tapered end 1 inner bottom part, be pressed on spacing elastic component 8 bottom the two side ends of opening 7, the concrete structure of spacing elastic component 8 is that the spring base 8B on spring 8A is formed by spring 8A and gland, spring base 8B is provided with the groove 9 relative with opening 7, is pressed on the end face of groove 9 both sides bottom the two side ends of opening 7.In the locked state, in lockhole 6, the long limit 5B of lock bolt 5 is relative with opening 7, and the length due to long limit 5B is greater than the width of opening 7, the therefore limited locking of connection-peg 2.When lock core shaft 3 rotates 90 degree, in lockhole 6, the minor face 5A of lock bolt 5 is relative with opening 7, and the length due to minor face 5A is less than the width of opening 7, and under the effect of spring 8A, spring base 8B ejects connection-peg 2 makes grafting lock unlatching.Above-described embodiment is only be described the preferred embodiment of the switching mechanism of a kind of grafting lock of the utility model; not the design of utility model and scope are limited; under the prerequisite not departing from the utility model scheme; the various external form modification that those skilled in the art make the technical solution of the utility model and improvement, all should fall into the protection domain of the switching mechanism of a kind of grafting lock of the utility model.
