Description

Technical Field

[0001] This utility model belongs to the field of LCD screen production technology, and in particular relates to a frozen testing cabinet for LCD screens. Background Technology

[0002] An LCD screen is an image display device made of liquid crystal material. It is commonly used in consumer electronics, industrial and medical applications, automotive displays, and public displays. During the production and processing of LCD screens, various performance tests are usually conducted. In order to simulate the display conditions of LCD screens in low-temperature environments, a cryogenic testing cabinet is generally used.

[0003] Existing LCD screen refrigeration testing cabinets generally consist of two parts: the cabinet body and the compression refrigeration system. The cabinet body is used to store the LCD screen and provide it with a closed space. The compression refrigeration system mainly consists of a compressor, condenser, evaporator, four-way valve, and capillary tube. The four-way valve changes the direction of refrigerant flow, thereby allowing the evaporator and condenser to interchange functions and provide a low-temperature or room-temperature environment to the cabinet body. However, during use, the compression refrigeration system generates some heat during the refrigeration process, which cannot be recovered and reused, resulting in heat loss and high costs. In addition, the cabinet body cannot fix LCD screens of different sizes, limiting its applicability and practicality.

[0004] To address these issues, we provide a liquid crystal display (LCD) refrigerated testing cabinet. Utility Model Content

[0005] The purpose of this utility model is to provide a liquid crystal display (LCD) screen freezing test cabinet. It stores the cold air generated during the reheating process through a cold air duct and stores the hot air generated during the cooling process through a hot air duct. At the same time, the cold air in the cold air duct and the hot air in the hot air duct assist in cooling and heating inside the cabinet, solving the problem of inconvenience in reducing energy loss in existing models. In addition, the sliding sleeve drives the U-shaped frame to move and fix the LCD screen through the U-shaped frame, solving the problem of inconvenience in placing LCD screens of various sizes for freezing test.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

The temperature control component includes an air distribution plate fixedly connected to the lower part of the cabinet body and a temperature control box fixedly connected to the rear end face of the cabinet body. Air outlet pipes are fixedly connected to the lower part of both outer walls of the temperature control box. The end of the air outlet pipe furthest from the temperature control box is fixedly connected to the air inlet end of the air distribution plate. Cold air ducts and hot air ducts are fixedly connected to the two outer walls of the temperature control box via mounting plates. Second fans are fixedly connected to the mounting plates, with the air inlets of the second fans extending into the interiors of the cold and hot air ducts respectively. The air outlets of the second fans are connected via… The third connecting pipe is fixedly connected to the air inlet end of the air distribution plate. The fourth connecting pipe is fixedly connected to the front end face of the hot air duct. The end of the fourth connecting pipe away from the hot air duct extends into the interior of the temperature control box. The inner side of the cabinet is also equipped with a placement component. The placement component includes a fixed frame fixedly connected to the inside of the cabinet. The upper and lower sides of the fixed frame are movably connected to the movable frame. The upper and lower sides of the movable frame are fixedly connected to the mounting frame at equal intervals. The left and right sides of the mounting frame are fixedly connected to the cross-shaped frame. The horizontal and vertical support arms of the cross-shaped frame are movably connected to the sliding sleeve. The front end face of the sliding sleeve is fixedly connected to the U-shaped frame.

[0008] A further feature of this invention is that cabinet doors are rotatably connected to both sides of the front end of the cabinet, and observation windows are fixedly connected to the end faces of the cabinet doors.

[0009] The present invention is further configured such that: a cooling chamber and a heating chamber are provided on the upper sides of the interior of the temperature control box through a partition, and an air supply chamber is provided on the lower side of the interior of the temperature control box through a partition. A first connecting pipe is passed through both sides of the partition. The top end of the first connecting pipe extends into the interior of the cooling chamber and the heating chamber respectively, and the bottom end of the first connecting pipe extends into the interior of the air supply chamber and is fixedly connected to a control valve.

[0010] A further feature of this invention is that air supply ducts are fixedly connected to both sides of the top of the temperature control box, a filter screen is fixedly connected to the top of the air supply duct, a first fan is fixedly connected to the upper part of the inside of the air supply duct, and a packing frame is fixedly connected to the lower part of the inside of the air supply duct.

[0011] A further feature of this invention is that a second connecting pipe is fixedly connected to the top of the air duct, and the end of the second connecting pipe away from the air duct extends to the inside of the cabinet and is fixedly connected to an air outlet hood, which is fixedly connected to the top of the inside of the cabinet.

[0012] A further feature of this invention is that: a collar is fitted on the upper and lower sides of the outer walls of both the cold air duct and the hot air duct; one side of the collar is fixedly connected to the outer wall of the mounting plate away from the temperature control box; a pad is fixedly connected to the lower side of the outer wall of the mounting plate; and the second fan is fixedly connected to the pad.

[0013] A further feature of this invention is that: slide rails are fixedly connected to the upper and lower sides of the outer walls of the fixed frames that are close to each other, and sliders are slidably connected inside the slide rails. One side of the slider extends to the outside of the slide rail and is fixedly connected to the outer walls of the two sides of the movable frame.

[0014] A further feature of this invention is that multiple positioning holes are evenly spaced on the rear end faces of the horizontal and vertical supports of the cross-shaped frame, and a threaded rod is threadedly connected to the rear end face of the sliding sleeve. One end of the threaded rod is threadedly connected to the inside of one of the positioning holes, and the other end of the threaded rod is fixedly connected to a knob.

[0015] This utility model has the following beneficial effects:

[0016] This invention, by incorporating a temperature control component, activates a second fan on the cold air duct when cooling is required inside the cabinet. This second fan directs the stored cold air from the cold air duct into the air distribution plate via a third connecting pipe, and the air distribution plate evenly distributes the cold air throughout the cabinet, thus cooling the auxiliary cabinet. When reheating is required inside the cabinet, the second fan on the hot air duct is activated, directing the hot air from the hot air duct into the air distribution plate. Meanwhile, the cold air inside the cabinet enters the cold air duct through the air outlet and the second connecting pipe for temporary storage, reducing energy consumption for cooling or reheating the cabinet and facilitating freezing tests on the LCD screen.

[0017] This invention features a placement component. Rotating a knob causes a threaded rod to rotate synchronously, moving the rod out of the positioning hole and applying external force to a sliding sleeve. This causes the sliding sleeve to move a U-shaped frame on the support arm of a cross-shaped frame. When the U-shaped frame reaches the designated position, rotating the knob again moves the threaded rod into a new positioning hole, thus fixing the LCD screen onto the U-shaped frame. This facilitates the placement of LCD screens of various sizes and allows for easy placement within a cabinet for freezing testing. Attached Figure Description
