Description

Tray locking mechanism and tray Technical Field The utility model relates to the technical field of trays, in particular to a tray locking mechanism and a tray. Background The food tray is a container for storing food and fresh products, can be wrapped by a preservative film, is simple and easy to use, and generally has two raw materials, namely a PP food tray or a PE food tray. The top end of the existing food tray mainly adopts an open type structure, so that food is easy to be directly scattered on the ground due to unexpected sliding of the tray in the moving process of the food tray, the use safety of the food tray is greatly reduced, the efficient use of the food tray is inconvenient, once the positioning structure is added on the periphery of the food tray frame, each time a worker needs to operate and lock the tray when putting the tray into the tray frame, the labor capacity of operators is greatly increased, the trays are required to be unlocked again when the trays are taken out of the tray frame, the labor intensity of the operators is greatly increased through reciprocating operation, time and labor are wasted in the taking process, and the efficiency is low. Disclosure of utility model The application aims to provide a tray locking mechanism and a tray, which are used for solving the problems in the prior art. The tray locking mechanism comprises a base frame with universal rollers, wherein a tray frame is fixedly arranged at the top of the base frame, a plurality of bottom plates are uniformly arranged on the tray frame, positioning holes are formed in the periphery of the top of the bottom plates, arc-shaped positioning blocks are movably arranged in the positioning holes, and a positioning frame is fixedly arranged in the positioning holes; The locating rack is keeping away from a plurality of extension spring is evenly installed to one side of arc locating piece, extension spring's top fixed mounting has the locating plate, the locating plate is keeping away from one side fixed mounting of extension spring has the locating lever, the top fixed mounting of locating lever has the activity in the locating hole the arc locating piece. Preferably, the size of the positioning hole is identical to that of the arc-shaped positioning block, and the arc-shaped positioning block penetrates through and moves outside the positioning hole.
