Abstract
The invention discloses a latch for a corrugated paper packaging box, which comprises a hollow cylindrical female latch which is provided with openings at two ends and at least one pair of bendable claws on the top circumferential edge, and a cylindrical male latch which is inserted into the bottom of the female latch to allow the bendable claws to bend outwards, wherein a clamping side is arranged at the outer side of the circumferential edge of the bottom end of the female latch, and L-shaped grooves which are arranged inwards from the edge of the bottom end of the female latch are respectively arranged on the two opposite sides of an inner surface; and projections through which the male latch is inserted into the L-shaped grooves are respectively arranged at the two opposite sides of an outer surface of the male latch, and a shifting plate which is used for rotating the male latch after the male latch is inserted into the female latch is arranged at the bottom end part of the male latch. After the latch provided by the invention is used, a heavy corrugated paper packaging box needs not to be nailed after being molded, but is directly locked by the latch. The combining method ofthe heavy corrugated paper packaging box is optimized, thus the packaging efficiency of the heavy corrugated paper packaging box is greatly improved.
Description
Technical field
The present invention relates to a kind of fluting board packing chest snap close, be mainly used in the heavy fluting board packing chest after the sealed moulding.
Background technology
Tradition corrugation package box with paper adopts the stitching molding mode, and for bigger heavy corrugated case, this mode is not easy to pack execute-in-place.
Summary of the invention
The object of the present invention is to provide a kind of fluting board packing chest snap close, it is simple in structure, can improve the packaging efficiency of heavy corrugated case greatly.
The present invention is achieved in that a kind of fluting board packing chest snap close, comprises that the nose-circle circumferential edges is provided with the hollow circular cylinder box of the both ends open of at least one pair of bent pawl, inserts the cylinder pin thread that makes folding outside the described bent pawl from described box bottom; The circumferential edges outside, described box bottom is provided with edge, and the relative both sides of inside face are respectively equipped with a L type groove of inwardly offering formation from described box bottom edge; The relative both sides of described pin thread cylinder outside face are respectively equipped with one and are used for described pin thread and insert thrust in the described L type groove by it, and its bottom is provided with a plate that pulls out that is used for after described pin thread the inserts described box described pin thread of rotation.
Further, described pin thread bottom is provided with a depressed area, and the described plate that pulls out is located in the described depressed area.
More excellent, described bent pawl is two pairs, evenly is laid in described box nose-circle circumferential edges.
Described bent pawl is in the diameter range of described box when bending inwards.
After using snap close of the present invention, just needn't carry out stitching again after the moulding of heavy fluting board packing chest, but directly carrying out sealed getting final product by this snap close, the present invention has been owing to optimized the combination of heavy corrugated packaging box, thereby improved the packaging efficiency that uses heavy corrugated packaging box greatly.
Description of drawings
Fig. 1 is a kind of fluting board packing chest that provides of the embodiment of the invention with the decomposition texture scheme drawing of snap close;
Fig. 2 is pin thread among Fig. 1 and the sealed scheme drawing of box.
The specific embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the present invention is further elaborated.
Shown in Fig. 1-2, a kind of fluting board packing chest snap close, comprise that the nose-circle circumferential edges is provided with the hollow circular cylinder box 1 of the both ends open of at least one pair of bent pawl 13, from described box bottom insert (direction shown in arrow Fig. 1) make as described in outer folding of bent pawl 13 and open cylinder pin thread 2; The circumferential edges outside, described box 1 bottom is provided with edge 11, the relative both sides of inside face are respectively equipped with a L type groove 12, described L type groove 12 is inwardly axially offered from described box bottom edge, end after circumferentially extending a segment distance again behind the inwardly axial straight line extension certain distance, form L type groove, wherein the circumferential extendible portion of these two L type grooves oppositely arranges; The relative both sides of described pin thread 2 cylinder outside faces are respectively equipped with one and are used for described pin thread and insert protrusion 21 in the described L type groove by it, its bottom be provided with one be used for after described pin thread the inserts described box described pin thread of rotation pull out plate 22.
Described bent pawl 13 comprises a foldable part and paperboard portion; Described foldable part and described box 1 nose-circle circumferential edges link together, and described paperboard portion is located at this foldable part other end, and with vertical setting of described foldable part face; Inserting when described foldable part under the thrust of the pin thread in the box from its root that is connected with box is outside roll over after, the paperboard face of described paperboard portion is substantially parallel with the periphery of described box.
Further, described pin thread bottom is provided with a depressed area 23, and the described plate 22 that pulls out is located in the described depressed area 23.
More excellent, described bent pawl 13 is two pairs, evenly is laid in described box 1 nose-circle circumferential edges.
Described bent pawl 13 is in the diameter range of described box 1 when bending inwards fully, so that box inserts in the cardboard perforate; The edge 11 that opens with the box other end when outwards bending blocks cardboard.
During use two-layer cardboard perforate is also alignd, insert box, then with two protrusions of pin thread with after the L type groove of box aligns, pin thread is inserted in the box, four bent pawls of box are outwards opened, and the plate that pulls out by the pin thread bottom makes pin thread rotation, direction shown in arrow among Fig. 2, be fixed in the box then, thereby with two-layer cardboard locking.
The above only is preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
