Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-5, the present invention provides a technical solution: a plastic lock hasp for a packing box comprises a hanging seat 1, a base 2, a fixed shaft 3, a fixed block 4, a first rotating shaft 5, a buckle plate 6, a second rotating shaft 7, a press hook 8, a torsion spring 9, a press hole 10, a lead sealing hole 11 and a mounting hole 12, wherein the base 2 is arranged at the bottom of the hanging seat 1, the fixed shaft 3 is arranged on the inner side of the middle part of the base 2, the fixed block 4 is integrally arranged on the inner side of the bottom of the base 2, the first rotating shaft 5 is connected to the inner side shaft of the top of the hanging seat 1 in a shaft mode, the buckle plate 6 is sleeved on the first rotating shaft 5, the second rotating shaft 7 is connected to the inner side shaft of the bottom of the buckle plate 6 in a shaft mode, the press hook 8 is sleeved on the second rotating shaft 7, the torsion spring 9 is arranged between the press hook 8 and the second rotating shaft 7, the press hole 10 is formed in the buckle plate 6 and;

the outer side of the fixing block 4 is designed to be an inclined structure, the bottom of the fixing block 4 is matched with the bottom of the pressing hook 8 in a concave-convex mode, when the buckle plate 6 is rotated, the bottom of the pressing hook 8 on the inner side of the bottom of the buckle plate 6 is contacted with the outer side of the fixing block 4, the pressing hook 8 rotates on the second rotating shaft 7 under the stress, the bottom of the pressing hook 8 can be clamped at the bottom of the fixing block 4, and the position of the buckle plate 6 is fixed;

the buckle plate 6 forms a rotating structure with the hanging seat 1 through the first rotating shaft 5, and the buckle plate 6, the hanging seat 1 and the base 2 are designed in a concave-shaped structure, so that the buckle plate 6 can be turned over on the hanging seat 1 through the first rotating shaft 5, and the buckle plate 6 can also enter the hanging seat 1 for fixing, and the occupied space is reduced;

mounting holes 12 are formed in the pinch plate 6 and the base 2, the pinch plate 6 corresponds to the mounting holes 12 of the base 2 in position, and the fixing lock is convenient to mount and use through the mounting holes 12, so that the safety performance is improved;

press hook 8 to constitute elasticity revolution mechanic between through torque spring 9 and second pivot 7 and buckle 6, and the outside of pressing hook 8 is provided with anti-skidding stripe, increases its frictional force through pressing hook 8 outside anti-skidding stripe, conveniently presses, presses hook 8 atress at buckle 6 internal rotation, can make it return the normal position through torque spring 9 simultaneously, conveniently presses hook 8's locking and fixed.

The working principle is as follows: when the plastic lock hasp for the packing box is used, as shown in figures 1-5, a hanging seat 1 and a base 2 are respectively fixed on the outer sides of a base and an upper cover of the packing box through fastening screws, when the plastic lock hasp is used, a buckle plate 6 can turn over on the hanging seat 1 through a first rotating shaft 5, so that the buckle plate 6 completely enters the hanging seat 1 and the base 2, the occupation of space is reduced, meanwhile, when the buckle plate 6 is turned over, the bottom of a press hook 8 on the inner side of the bottom of the buckle plate 6 is contacted with the outer side of a fixed block 4, the press hook 8 rotates on a second rotating shaft 7 under the stress, the buckle plate 6 can return to the original position through a torsion spring 9, so that the bottom of the press hook 8 can be clamped at the bottom of the fixed block 4, meanwhile, the top of the press hook 8 enters a fixed shaft 3, the press hook 8 is locked through bidirectional fixation, the position of the buckle plate 6 is further fixed, and the hanging seat, on the contrary, when the box needs to be opened, the pressing hook 8 is pressed by manually penetrating through the pressing hole 10, so that the bottom of the pressing hook 8 is separated from the fixed block 4, the top of the pressing hook 8 is separated from the fixed shaft 3, then the buckle plate 6 is pulled upwards, the buckle plate 6 loses the limiting force on the base 2, the base 2 is separated from the hanging seat 1, and the box is convenient to open;

next, as shown in fig. 1 to 4, the lock can be installed through the installation hole 12 on the base 2 and the buckle plate 6, the lock is fixed in the installation hole 12, and the lock is rotated conventionally, so that the top of the pressing hook 8 is limited by the fixing piece on the lock and cannot be pushed, and the buckle plate 6 cannot be opened, thereby further improving the safety performance.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
