Transfer box automatic locking device

Abstract

The invention discloses a transfer box automatic locking device. The transfer box automatic locking device comprises a box cover locking mechanism and a box body locking mechanism; the box cover locking mechanism comprises a box cover fixed base, an unlocking box opening lifting handle, a lock tongue body, a lock tongue positioning block and a spring; the box cover fixed base is provided with a lifting handle notch and a lock tongue chute; the unlocking box opening lifting handle is arranged in the lifting handle notch; the lock tongue body is arranged in the lock tongue chute; a rotating armof the unlocking box opening lifting handle is hinged to the lock tongue body; the lock tongue positioning block is fixed on the box cover fixed base; the spring is correspondingly mounted between thelock tongue positioning block and the lock tongue; and when the unlocking box opening lifting handle is pulled up, the unlocking box opening lifting handle drives the lock tongue on the lock tongue body to separate from the box body locking mechanism to open box covers with the groove wall of the lifting handle notch as a rotating support surface. After the structure is adopted, the transfer boxautomatic locking device has the advantages of simple and reasonable structure, convenient and flexible operation, automatic locking, high reliability, high safety and convenience to recycle transferboxes.

Description

technical field [0001] The invention relates to the technical field of bags, in particular to an automatic locking device for a turnover box used in conjunction with a turnover box. Background technique [0002] In order to improve the recycling rate of resources and reduce the waste of resources, turnover boxes are widely used in factory turnover, logistics transportation turnover and express transportation turnover, but there are the following problems in the process of use: First, the existing turnover boxes are mainly packaged with adhesive tape, not It is conducive to disassembly and recycling, especially the express boxes are discarded and scrapped after use. Due to the adhesive tape, the discarded and recycled express boxes are also difficult to handle, and the waste of resources is very serious. Second, if you don’t use adhesive tape and only use face sheets to package, not only the strength is poor in the process of logistics and rapid packaging turnover, but it is ...

Problems solved by technology

[0002] In order to improve the recycling rate of resources and reduce the waste of resources, turnover boxes are widely used in factory turnover, logistics transportation turnover and express transportation turnover, but there are the following problems in the process of use: First, the existing turnover boxes are mainly packaged with adhesive tape, not Facilitate disassembly and recycling, especially the express boxes are discarded after use. Due to the adhesive tape, the discarded and recycled express boxes are also difficult to handle, and the waste of resources is very serious.

Second, if you don’t use adhesive tape and only use face sheets to package, not only the strength is poor in the process of logistics and rapid packaging turnover, but it is also not easy to be found after the circulation link is opened, which greatly increases the unsafe factors in the use of turnover boxes, and the safety performance is improved. not guaranteed

Third, although there are also turnover boxes using locking devices, the existing locking devices have complex structures, unreasonable designs, high production costs, inconvenient operation and unreliable use

In response to the above problems, many manufacturers and people of insight have developed and developed, but so far no satisfactory products have come out.
