Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.

As shown in fig. 1-3, the showcase of the preferred embodiment of the present invention mainly includes a cabinet body 1, a door body 2, a conversion partition plate 3, an upper duct baffle 5 and a lower duct baffle 6.

Wherein, the front side of the cabinet body 1 is provided with a cabinet door opening, the door body 2 is arranged at the cabinet door opening in an openable manner, and a sealing piece 21 is arranged on one side facing the inside of the cabinet body 1. For moving convenience, the bottom of the cabinet body 1 is also provided with universal wheels 14.

The conversion partition plate 3 is arranged inside the cabinet body 1 and divides the cabinet body 1 into an upper chamber 11 and a lower chamber 12.

Referring to fig. 2, the upper air duct baffle 5 is disposed in the upper chamber 11, an upper air duct 51 is formed between the upper air duct baffle 5 and the rear side of the cabinet body 1, an upper vent 52 is disposed between the bottom of the upper air duct 51 and the upper chamber 11, and a plurality of air outlets (not shown in the figure) are disposed on the upper air duct baffle 5.

Referring to fig. 3, the lower duct baffle 6 is disposed at a position corresponding to the upper duct baffle 5 in the lower chamber 12, and forms a lower duct 61 with the rear side of the cabinet 1, a lower vent 63 is disposed between the bottom of the lower duct 61 and the lower chamber 12, and a plurality of air outlets (not shown in the figure) are disposed on the lower duct baffle 6.

The upper duct 51 communicates with the lower duct 61 to form a rear duct.

Referring to fig. 4 and 5, the transfer partition 33 includes a guide groove 31, a push-pull partition 32, and a duct partition 33.

The guide grooves 31 are symmetrically provided on the left and right sides of the cabinet 11. The guide groove 31 includes a first groove section 311 and a second groove section 312, the first groove section 311 is horizontally disposed, and a circulating air duct is formed between the two first groove sections 311. The second slot section 312 is connected to one end of the first slot section 311 near the rear side of the cabinet 1, so that the L-shaped guide slot 31 is integrally formed. And the side of the second groove section 312 abuts against the side of the lower duct baffle 6.

The push-pull partition 32 is slidably disposed in the guide groove 31, and a first push block 321 and a second push block 327 are respectively disposed at predetermined positions on the push-pull partition 32.

The air duct partition 33 is movably disposed at a position corresponding to the upper ventilation opening 52 on the rear side of the cabinet 1.

The double-chamber switching process of the display cabinet provided by the embodiment of the invention is as follows:

referring to fig. 6, when the push-pull partition plate 32 moves to the first predetermined position, the push-pull partition plate 32 spreads over the first groove section 311, thereby closing the circulating air passage. The front end of the push-pull partition 32 is in contact with the sealing member 21 (see fig. 8), thereby closing the front air passage. And the second push block 327 drives the air duct partition 33 to move to partition the upper air duct 51 and the lower air duct 61, thereby closing the rear air duct. That is, when the push-pull partition 32 is located at the first predetermined position, the upper chamber 11 and the lower chamber 12 become two independent chambers which are not communicated.

Referring to fig. 7, when the push-pull diaphragm 32 moves from the first predetermined position to the second predetermined position along the second groove section 312, the front end of the push-pull diaphragm 32 is separated from the sealing member 21 during the movement, thereby opening the front air passage. As the push-pull partition 32 moves toward the second slot section 312, the push-pull partition 32 is spread less and less in the first slot section 311, thereby gradually opening the circulating air passage. When the push-pull partition 32 moves to the second predetermined position (i.e., the position shown in fig. 7), the first push block 321 drives the air duct partition 33 to move to communicate the upper air duct 51 and the lower air duct 61, thereby opening the rear air duct. That is, when the push-pull partition 32 is located at the second predetermined position, the upper chamber 11 and the lower chamber 12 are communicated to form an integral chamber.

In the above embodiments, the upper duct baffle 5 and the lower duct baffle 6 are provided to form the rear duct, and the duct partition 33 is provided to control the closing or opening of the rear duct, which are not essential features, but are further preferred embodiments for further improving the efficiency of the air circulation in the chamber.

When the upper air duct baffle 5, the lower air duct baffle 6 and the air duct partition 33 are not arranged, the side surface of the second groove section 312 is arranged close to the rear side surface of the cabinet body 11, so that only a circulating air duct and a front air duct are arranged between the upper chamber 11 and the lower chamber 12.

The invention provides a display cabinet, which is provided with a conversion clapboard 3 for dividing the interior of the display cabinet into two chambers, and controls the opening and closing of an air duct by pushing and pulling the conversion clapboard 3 back and forth, so that the two chambers are communicated or independent. When switching different functions, push-and-pull conversion baffle 3 around only needing does not need to move the goods that the baffle was deposited from top to bottom, and it is strong to adjust the convenience, and space utilization is high.
