Description

Multi-temperature-zone refrigerator carriage structure Technical Field The utility model relates to the technical field of refrigerated transport equipment, in particular to a multi-temperature-zone refrigerated carriage structure. Background In cold chain logistics transportation, a plurality of goods with different temperature requirements are often required to be transported at the same time, for example, fresh vegetables and fruits are required to be transported in a fresh-keeping temperature range of 0-5 ℃, frozen meat and seafood are required to be stored in a freezing temperature range below-18 ℃, the conventional single-temperature-zone refrigerator carriage cannot meet the requirement of transporting a plurality of goods at the same time, and if a plurality of refrigerator cars with different temperature zones are used for transporting respectively, transportation cost and resource waste can be greatly increased; The existing multi-temperature-zone refrigerator carriage realizes multi-temperature zone division, but has the following problems that the sealing method used by the existing refrigerator carriage is to install strip-shaped A sealing strips and plate-shaped B sealing strips on carriage doors at two sides, when the carriage doors are closed, the B sealing strips are abutted against the A sealing strips, and then the sealing strips are contracted inwards by the temperature and the air pressure in the subsequent carriage so as to achieve the sealing effect, but the structure needs extremely large force when the carriage is opened due to overlarge internal pressure, and the two sealing strips are aligned A, B when the carriage is closed, so that the loading and unloading time is delayed, and therefore, the problems are solved. Disclosure of utility model The utility model aims to solve the defects in the prior art and provides a multi-temperature-zone refrigerator carriage structure. In order to achieve the aim, the multi-temperature-zone refrigerator carriage structure comprises a carriage body, wherein the front end of the carriage body is hinged with a carriage door, a sealing mechanism is arranged in the carriage door, two adjusting rods are arranged in the carriage body, and a folding mechanism is arranged on each adjusting rod. Preferably, the lock plate is hinged on the carriage door, the lock ring is hinged on the lock plate, one end of the lock ring is hinged with the push ring, one side of the carriage body is fixedly connected with the L-shaped drag hook, and one end of the lock ring is clamped with the drag hook. Preferably, the sealing mechanism comprises a valve rotatably arranged on the carriage door and a sealing layer arranged on the inner side surface of the carriage door, a threaded rod is fixedly connected to the valve, and the sealing layer is in threaded connection with the threaded rod. Preferably, four guide rods are arranged on the inner side of the compartment door, and the sealing layer is spliced on the guide rods. Preferably, the folding mechanism comprises two groups of adjusting rings sleeved on the adjusting rods and placing plates arranged on the inner sides of the two adjusting rods, a plurality of adjusting holes are formed in the adjusting rods at equal intervals, positioning holes matched with the adjusting holes are formed in the adjusting rings, a limiting block is inserted on one side of each adjusting ring, one end of each limiting block is fixedly connected with a limiting ring, and the other end of each limiting ring is fixedly connected with the placing plates. Preferably, the two ends of the placing plate are fixedly connected with threaded blocks, the threaded blocks penetrate through the limiting rings, and the threaded blocks are connected with threaded cylinders in a threaded manner. Compared with the prior art, the utility model has the beneficial effects that the sealing layer is conveniently driven to move towards the inside of the carriage body by rotating the valve, so that the inside of the carriage body is sealed, the sealing layer can squeeze the air in the carriage body when moving towards the carriage body, thereby forming suction force, enhancing the tightness, only the threaded rod is required to be rotated when the carriage body is opened, the force required for opening the sealing layer is reduced by the threaded rod, the opening and closing of the carriage door are simplified, the unloading time is saved, and finally the problem that the unloading time is influenced because the conventional carriage door is inconvenient to open is solved.
