Description

Self-locking packing box

Technical Field

The utility model relates to a packing box, concretely relates to from locking-type packing box.

Background

At present, the express delivery packing material that most trade companies still used now all is article such as carton, plastic bag, sticky tape, and current packing box for the express delivery is mostly uncovered formula, needs the manual work to adopt the sticky tape joint sealing just can accomplish product packaging, and joint sealing speed is slow, and cost increase easily influences product packaging outward appearance because of the case lid fifty percent discount is not neat or tape-stripping is not in place moreover at the joint sealing in-process, also can't play fine protecting effect simultaneously. When the customer uses, need to use sharp ware to cut open the carton and take out the product, also cause the product fish tail easily in this process, influence outward appearance or use. Moreover, similar articles such as plastic bags, tapes, double-sided tapes and the like are difficult to degrade, and once thrown away into the natural environment, the articles tend to damage the nature to a certain extent. The express delivery sticky tape is made by plastics and glue, belongs to difficult degradation material, if handle improperly, abandons at will, burns or the landfill can cause the pollution to the soil atmosphere. Therefore, it is necessary to design a packing box without sealing the box by double-sided adhesive tape and adhesive tape.

Disclosure of Invention

An object of the utility model is to overcome prior art's defect, provide a simple structure, stable performance is reliable, packing speed is fast, need not the sticky tape joint sealing, enough protect the product well from locking-type packing box.

For realizing the above-mentioned purpose, the utility model discloses a from locking-type packing box, including the box, respectively with box disjunctor connected's case apron, bottom of the case board, the case apron including two side shields of symmetry coincide on the box, the outer apron on interior apron, the coincide of coincide on two side shields, the one end of outer apron bend and be provided with the jam plate, interior apron on be provided with jam plate matched with jack, the jam plate alternate in the jack, the box on correspond jack department and be provided with the hasp board, the both sides of hasp board bend respectively and be provided with the spring bolt, the jam plate on be provided with spring bolt matched with hasp hole, the spring bolt block in the hasp hole, and constitute the joint cooperation of hasp board and jam plate.

The beneficial effect of above-mentioned structure is: the lock plate is provided with a lock tongue in a bending way, the lock tongue penetrates into the lock hole, the lock tongue can fully utilize the stretching elasticity of the paper board, the lock tongue naturally stretches and springs out after being inserted into the lock hole, and the lock tongue is buckled with the lock plate, so that the self-locking function of the packing box can be realized. The lock tongue of the packing box is inserted into the lock catch hole, and the packing box can be locked immediately after being inserted without sealing a box by using double-sided adhesive tapes and adhesive tapes, so that the packing box is convenient, the plastic consumption is greatly reduced, the resources are saved, the cost is critical, the whole box is degradable, and the packing box is environment-friendly and pollution-free. After the spring bolt inserts the hasp hole, the spring bolt passes through the extension elasticity of cardboard, and spring bolt and jam plate looks closure, other people can not open at will, can only demolish the spring bolt through the destructiveness, just can open this packing box to this carton still possesses the theftproof function. Therefore, the packing box has the advantages of simple structure, stable and reliable performance, high packing speed, no need of sealing the box by using an adhesive tape and good product protection.

Particularly, the bottom plate of the case including the coincide set up on the box and be the interior bottom plate of "concave" style of calligraphy, the side bottom plate on the bottom plate including two symmetry superpositions, coincide the outer bottom plate on two side bottom plates, two side bottom plates and interior bottom plate between be formed with the spliced eye, one of outer bottom plate serve and have the inserted sheet with spliced eye matched with, the inserted sheet alternate in the spliced eye, and constitute the joint cooperation of outer bottom plate and two side bottom plates, interior bottom plate. The box bottom plate is formed by buckling the outer bottom plate, the two side bottom plates and the inner bottom plate, so that the strength of the box bottom plate is better, the protection effect is better, the packaged materials are not extruded, the box bottom plate is designed in a self-locking structure, double-sided adhesive tapes and adhesive tape box sealing are not needed, the box sealing machine is more environment-friendly, the box sealing efficiency is higher, and the cost is lower.

Particularly, one end of the lock tongue is provided with an arc-shaped insertion surface, and one side of the lock tongue is provided with a guide inclined surface in transition connection with the arc-shaped insertion surface. The arc surface insertion surface and the guide inclined surface are respectively arranged on the spring bolt, so that the spring bolt can be ensured to be rapidly inserted into the lock catch hole, and the box sealing efficiency of the packing box is improved.

In particular, the two side cover plates are respectively provided with a yielding groove on one side facing the locking plate. Be provided with the groove of stepping down on two side cover boards to can guarantee that two curb plates can not interfere the inserting of spring bolt, thereby be favorable to improving the joint sealing efficiency of this packing box.

In particular, the insertion holes are arranged on the folds of the inner cover plate. The jack sets up on the crease of inner cover plate to be convenient for the jam plate inserts in the jack, be favorable to improving the packing efficiency of this packing box.
