A transverse through hole is arranged at the back end of the bolt; two slip bolts whose head parts extend from the surface of the bolt are arranged in the transverse through hole; the surface of the head part of the slip bolts are spherical surface, conical surface or double-wedge-shaped surface; an offsetting spring whose two ends contact respectively with the tail of the slip bolt is arranged in the transverse through hole. The useful effects of the utility model are that: the structure is simple; in addition, a reliably self-locking function can be realized when the packing blot is inserted into the connecting through hole, and thus the box bodies mentioned above can form an integrated packing box; moreover, the blot can be inserted into or pulled out the connecting through hole conveniently and quickly.
Description
Affiliated technical field
The utility model relates to a kind of attaching parts, and the inside and outside box body or the upper and lower box body that relate in particular to packing box connect into holistic connection lock pin.
Background technology
Packing box with inside and outside box body or upper and lower box body structure places packaged object in box after, need to adopt attaching parts that both are connected to form an entire package box.Existing attaching parts adopts rope and lock pin more, promptly on the box wall of inside and outside box body or upper and lower box body, have at least one pair of cooresponding connecting through hole, walk therebetween with rope, or in connecting through hole, insert the lock pin have auto-lock function both are connected to form an entire package box.
The existing lock pin that has auto-lock function has one and the contacted baffle plate of box body outer wall, one latch that is used to pass the box body connecting through hole is arranged on this baffle plate, latch is made up of the elastic strip that inwardly shrinks again after outwardly-bent a plurality of its afterbodys, and the profile at the self-locking position that is made of the crooked position of each elastic strip is greater than the profile of box body connecting through hole.In the process of inserting lock pin, under the effect of the axial force that applies, inwardly shrink after the crooked position of each elastic strip and the edge contact of connecting through hole, after crooked position is crossed connecting through hole, each elastic strip resilience, its crooked position then is stuck on the inwall of box body connecting through hole periphery, thereby inside and outside box or upper and lower box body are connected to form an entire package box, and realizes self-locking.
The existing major defect of above-mentioned lock pin is; structure is comparatively complicated; use inconvenient; as it is preceding owing to the reasons such as collision that take place in transportation or the stacking to peg graft; regular meeting causes the relative position between each elastic strip of forming latch to change; when its relative position is varied down to a certain degree; lock pin can lose auto-lock function; and when becomeing greater to a certain degree; then can not successfully be inserted in the box body connecting through hole; therefore usually need to regulate the opening width of its front end in use, use inconvenience, and influenced production efficiency.
The utility model content
In order to overcome existing packing box detent configuration comparatively complexity and the deficiency of using inconvenience, technical problem to be solved in the utility model provides a kind of structure and simplifies relatively, can realize self-locking, and insert the box body connecting through hole and therefrom extract all very convenient, fast packing box lock pin.
The technical scheme that its technical matters that solves the utility model adopts is: the latch that packing box lock pin of the present utility model includes baffle plate and extended back by baffle plate, it is characterized in that: have cross through hole on the rear end of described latch, be provided with two slip dead bolts that its head stretches out latch surface in the described cross through hole, the surface of the overhanging head of described slip dead bolt is sphere, the conical surface or double-wedge face, also is provided with the retracing spring that its two ends contact with the afterbody of described slip dead bolt respectively in the described axially extending bore.
The two-port place of described cross through hole has described two the slide lock tongue portions of control to stretch out the position limiting structure of degree, and the effect of position limiting structure is that described slip dead bolt can not be skidded off from integral body in the described cross through hole.
Described latch is and the suitable cylinder of packing box box body connecting through hole, in the process of the connecting through hole of latch on inserting the packing box box body, the head of described slip dead bolt is along contracting in the described cross through hole, and after head is crossed connecting through hole, the head of described slip dead bolt is overhanging under the effect of described retracing spring and be stuck on the inwall of box body, this moment, the rear surface of described baffle plate contacted with the box body outer wall, thereby reach the purpose of self-locking, and inside and outside box body or upper and lower box body are connected to form an entire package box.Outwards stir and fasten described baffle plate, the head of described slip dead bolt after head is crossed the box body connecting through hole, gets final product open compact along contracting in the described cross through hole.
The beneficial effects of the utility model are, simple in structure, can realize the failure-free self-locking after inserting the connecting through hole on the packing box, thereby inside and outside box body or upper and lower box body are connected to form an entire package box, and insert, to extract connecting through hole all very convenient and quick.
Packing box lock pin of the present utility model is especially suitable for use as the attaching parts of the high-grade wine box with inside and outside box body or upper and lower box body structure.
