Description

Technical Field

[0001] This utility model belongs to the field of television production technology, and in particular relates to a low-temperature freezing device for sampling inspection in television production. Background Technology

[0002] Televisions are common household appliances. A television mainly consists of a display panel, image processing engine, power board, motherboard, sound system, and mechanical structure. After the television is manufactured, it needs to be sampled and tested. Low-temperature freezing equipment is a professional device used to simulate extreme low-temperature environments to conduct reliability tests on the entire television set or key components. By simulating harsh low-temperature environments, sampled televisions are subjected to "cold resistance tests" to ensure the durability and reliability of the products leaving the factory.

[0003] However, it still has the following drawbacks in practical use: The existing low-temperature freezing equipment used for sampling and testing in television production requires manual handling of televisions one by one, which is labor-intensive and inefficient. 2. Existing low-temperature refrigeration equipment used for sampling inspection in television production requires frequent opening and closing of the cabinet doors, resulting in significant energy loss due to cooling diffusion. Furthermore, the low internal temperature of the refrigeration equipment increases the risk of frostbite for workers. Therefore, we provide a low-temperature refrigeration equipment for sampling inspection in television production to address the aforementioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a low-temperature freezing device for sampling inspection in television production. By setting up a pull-out component and using a tiltable and rotatable rotating frame, it is convenient for workers to quickly pick up and put in multiple televisions, saving time and effort and increasing work efficiency. Furthermore, by using a pre-cooling cabinet and a fan, the fan runs to send cold air from the freezing cabinet into the pre-cooling cabinet, thereby quickly raising the temperature in the freezing cabinet and preventing frostbite for workers. At the same time, it reduces the diffusion of cold air and reduces energy loss.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a low-temperature freezing device for sampling inspection in television production, including a freezer and a pre-cooling cabinet disposed on one side thereon.

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example 1

[0022] Please see Figures 1 to 3 This utility model is a low-temperature freezing device for sampling inspection in television production, including a freezer 100 and a pre-cooling cabinet 200 disposed on one side thereon. Both the freezer 100 and the pre-cooling cabinet 200 have a grid plate 102 disposed on the lower part of their interiors, and a fan 300 is disposed between the freezer 100 and the pre-cooling cabinet 200.

[0023] Specifically, both sides of the front face of the freezer 100 and the pre-cooling cabinet 200 are movably connected to the cabinet door 101 via hinges. A first air pipe 103 is provided on the upper side wall of the freezer 100; an air outlet pipe 104 is provided on the lower side wall of the freezer 100; a second air pipe 201 is provided on the upper side wall of the pre-cooling cabinet 200; and an air inlet pipe 202 is provided on the lower side wall of the pre-cooling cabinet 200. The other end of the air outlet pipe 104 is connected to the air inlet of the fan 300 via a pipe connector, and the other end of the air inlet pipe 202 is connected to the air outlet of the fan 300 via a pipe connector.

[0024] Furthermore, the pre-cooling cabinet 200 does not require refrigeration equipment, only an insulation structure. The fan 300 is used to adjust the position of the cold air, and the pipe joint serves as the pipe connection.

[0025] The operation process of this embodiment is as follows: multiple televisions requiring low-temperature testing are placed inside the placement rack 406, and then sent to the freezer 100 and pre-cooling cabinet 200 in batches. The televisions are pre-cooled by the pre-cooling cabinet 200. After the televisions are pre-cooled, the placement rack 406 is placed into the freezer 100 for low-temperature cooling testing. After the low-temperature cooling test of the televisions is completed, the fan 300 is started. The fan 300 runs and draws cold air from the freezer 100 through the exhaust pipe 104, and sends it into the pre-cooling cabinet 200 through the intake pipe 202, thereby quickly raising the temperature in the freezer 100 and preventing frostbite for the staff during operation. At the same time, sending cold air into the pre-cooling cabinet 200 reduces cold air diffusion and reduces energy loss. Example 2

[0026] Please see Figure 3 and Figure 4 Based on Embodiment 1, the difference from the first embodiment is that a pull-out assembly 400 is provided. The pull-out assembly 400 includes a support plate 401 installed on the surface of the grid plate 102 and side plates 403 fixedly installed at both ends of the support plate 401. This solves the problem that the existing low-temperature freezing device used for sampling inspection in television production requires manual handling of televisions one by one, which is labor-intensive and inefficient.

[0027] Specifically, a rotating groove 401a is provided in the middle of the upper surface of the pallet 401. Auxiliary rollers 402 are evenly spaced and rotated inside the rotating groove 401a from front to back. A sliding groove 403a is provided on the upper inner wall of the side plate 403. Mounting plates 403b are fixedly provided at both the front and rear ends of the outer wall of the side plate 403. The mounting plates 403b are bolted to the surface of the grid plate 102. A bracket 404 is installed above the pallet 401. Sliding rods 404a are fixedly provided on both sides of the bracket 404. The sliding rods 404a are slidably installed inside the adjacent sliding grooves 403a. A rotating frame 405 is rotatably installed at the front end of the bracket 404. The front end of the rotating frame 405 is movably connected to the sealing door 405a through a hinge. A placement frame 406 is placed inside the rotating frame 405. Wheels 406a are installed at the four corners of the bottom of the placement frame 406.

[0028] Furthermore, bolts can be used to assemble and disassemble the pull-out assembly 400, the slide bar 404a and the slide groove 403a serve to guide and assist the movement of the bracket 404 and the rotating frame 405, the auxiliary roller 402 is used to assist the movement of the bracket 404 and the rotating frame 405, and the sealing door 405a can be fixed by a pin.

[0029] The operation process of this embodiment is as follows: When the placement rack 406 is sent into the freezer 100 or pre-cooling cabinet 200, the rotating rack 405 is first pulled out. The rotating rack 405 and the bracket 404 are connected by a hinge. Therefore, the bracket 404 moves under the connecting pull of the rotating rack 405 and with the assistance of the slide rod 404a and the slide groove 403a. After the rotating rack 405 is fully pulled out, it rotates around the hinge. At this time, the end of the rotating rack 405 touches the ground and tilts. Then the sealing door 405a is opened, and the placement rack 406 is pushed into the bracket 404 and the rotating rack 405. Finally, under the action of the auxiliary roller 402, the bracket 404 and the rotating rack 405 are pushed into the freezer 100. The same process is used to take out the placement rack 406. This makes it easier for staff to quickly pick up and put in multiple TVs, saving time and effort and increasing work efficiency.
