Abstract

The invention discloses a self-locking anti-releasing hasp for a packaging box. The hasp mainly comprises a pulling handle, a spring bolt, a cover plate, a spring bolt reset spring, a hasp rotating shaft, a bolt fixing pin, a baffle plate and a fixing base, the spring bolt and the spring bolt reset spring are designed, a spring bolt pressing plate is pressed to compress the spring bolt reset spring so as to realize opening, the defects that in the prior art, a hasp is easy to shake when a matching gap between a fixing base and a pulling handle is excessively large, and the hasp is difficult toopen due to tight matching and may cause the pulling handle to break when the matching gap between the fixing base and the pulling handle is small. The buckle for the packaging box is assembled on abox cover, the box cover and a box body can be buckled by slightly buckling downwards the pulling handle with slight force, only the spring bolt pressing plate needs to be pressed if opening is required, the operation is simple, buckling and opening processes are flexible and labor-saving, and the requirement of automatic operation is met.

Description

technical field [0001] The invention belongs to the field of product packaging equipment, and in particular relates to a self-locking anti-off buckle for a packaging box. Background technique [0002] The packaging boxes in the prior art need to realize the locking and opening functions when loading and transferring items. The commonly used locking devices are mostly hasps or anti-off hooks. During transportation or loading and unloading, due to the shaking of the box or the impact of external When the buckle is easy to loosen, break, and open automatically, the items in the packing box will be lost or damaged, which will seriously affect the sealing performance and safety performance of the packing box. [0003] In order to solve the defect that the hasp of the packaging box is easy to loosen and open automatically, the hasp devices used in emergency boxes or household storage boxes in the prior art are mostly tight fit or interference fit, resulting in that once the hasp i...
