Description

Technical Field

[0001] The utility model relates to the technical field of storage containers, in particular to a storage box. Background Art

[0002] Cold storage is a type of refrigeration equipment. Cold storage refers to the use of artificial means to create an environment with different temperature or humidity from the outdoor environment. It is also a constant temperature and humidity storage equipment for food, liquids, chemicals, medicines, vaccines, scientific experiments and other items. Cold storage is usually located near the transportation port or place of origin. Compared with refrigerators, cold storage has a larger refrigeration area and a common refrigeration principle. The existing plastic boxes will become brittle after a period of use, because the plasticizers in plastic products lose their activity in an environment with relatively low temperatures. Frequent replacement leads to an increase in the cost of use. Another problem with plastic boxes is that they cannot be overlapped in large quantities because they are not hard enough. After overlapping, agricultural products will be crushed and cannot be overlapped in large quantities. In ordinary warehouses, the existing storage boxes also have unstable box overlaps. Although some metal boxes can be overlapped, they are not convenient to store when idle. To this end, we propose a storage box. Summary of the invention

[0003] The technical problem to be solved by the utility model is to overcome the existing defects and provide a storage box with good antifreeze performance and sufficient hardness, which can be reused, and multiple storage boxes can be overlapped and used together, thereby saving warehouse space and improving warehouse utilization efficiency, and agricultural products will not be crushed.

The welded main frame 2 and sub-frame 2 serve as a base to increase stability.

[0010] Furthermore, the main frame 1 includes a support ear, a main bracket, a fixing pin and a socket. There are four support ears, and two of them are fixed in a group on the left and right sides of the top surface of the bottom of the box. The inside of each group of support ears is slidably connected to the main bracket. A fixing pin is fixed on the side of the main bracket, and the fixing pin is slidably connected to the fixing groove opened on the side of the support ear. A socket is opened at the top of the inside of the main bracket, and the fixing pin slides in the fixing groove inside the support ear to facilitate folding of the main frame 1.

[0011] Furthermore, the sub-frame one includes a sub-bracket, a baffle, a placement seat and a handle, there are four placement seats and they are fixed in groups of two on the front and rear sides of the top surface of the bottom of the box respectively, the sub-bracket is rotatably connected inside the placement seat, there are two baffles and they are respectively fixed in the middle parts of the front and rear sides of the top surface of the bottom of the box, the sub-bracket is snap-connected with the baffle, and a handle is slidably connected in the through hole on the side of the sub-bracket, the sub-bracket rotating in the placement seat can fold the sub-frame one, the set baffle facilitates the limiting function of the sub-frame together, and at the same time, the handle and the corresponding plug-in can assemble and fix the main frame one and the sub-frame one.

[0012] Furthermore, the supporting steel is one of a square tube, a round tube and an inverted triangle steel bar.

[0013] Furthermore, the base column is a square steel bar or a square supporting leg.

[0014] Furthermore, the steel bar is chrome steel.

[0015] Furthermore, there are at least two base frames which are respectively welded to the bottom surface of the bottom column, and the base frame is a triangular steel frame.

[0016] Furthermore, there are six base frames and they are of trapezoidal structure.
