Description

Technical Field

[0001] The utility model relates to the technical field of high and low temperature test chambers, and specifically relates to a high and low temperature test chamber with controllable temperature. Background Technique

[0002] High and low temperature test chamber products can simulate the temperature change law in the atmospheric environment. It is mainly aimed at the adaptability test of electrical appliances, electronic products, and other components and other materials during transportation and use in high and low temperature comprehensive environments.

[0003] According to a Chinese patent with the publication number "CN219273080U" which discloses a high and low temperature test chamber with controllable temperature, it relates to the technical field of high and low temperature test chambers, including a test chamber. A heating wire for heating the air inside the test chamber is arranged inside the test chamber. It also includes a pre-cooling chamber. The test chamber and the pre-cooling chamber are connected through two pipelines, so that a path for the internal circulation of hot air or cold air is formed between the test chamber and the pre-cooling chamber; a closing control device and a temperature control and adjustment device are respectively arranged at both ends of each pipeline. In this utility model, the air door assembly can be fixed at any position between closing and 90 degrees. When the test chamber conducts a high temperature test, injecting cold air with a controllable speed through the air door in the pre-cooling area can reduce the heating speed of the test area, and at the same time ensure a constant heating speed. When the test chamber conducts a low temperature test, controlling the cold air flow rate flowing in through the air door in the pre-cooling area can control the cooling speed and accuracy of the test area, which can greatly improve the test accuracy and test efficiency of the product.

[0004] However: Although this patent can conduct low temperature experiments on experimental products through refrigeration equipment, during the low temperature experiment process, frost may appear on the inner walls on both sides of the box body. In the prior art, the inner wall of the box body is usually defrosted manually. Manual defrosting not only takes time and effort, but also increases the labor cost of the factory. Therefore, a high and low temperature test chamber with controllable temperature is proposed to solve the above-mentioned problems. Content of the Utility Model

In the description of the present utility model, the meaning of "several" is two or more, unless otherwise specifically defined.

[0027] Please refer to Figures 1-4 , an embodiment of the present utility model is: a high and low temperature test chamber with controllable temperature, including a box body 1, and a defrosting mechanism 2 is arranged inside the box body 1; the defrosting mechanism 2 includes two groups of vertical sliding rods 21, two groups of cross rods 22, two groups of scraping plates 23, a horizontal sliding rod 24, two first triangular top blocks 25, two second triangular top blocks 26, two brackets 27, and an electric telescopic rod 28; the vertical sliding rods 21 are fixedly connected to the bottom inner wall of the box body 1, the cross rods 22 are slidably connected to the vertical sliding rods 21 through sliding sleeves, the number of each group of cross rods 22 is five, and they are respectively arranged in an array, the scraping plates 23 are fixedly connected to one side of the cross rods 22 close to the inner wall of the box body 1, one end of the scraping plates 23 is slidably connected to the inner wall of the box body 1, the two first triangular top blocks 25 are respectively fixedly connected to the left and right ends of the horizontal sliding rod 24, the second triangular top blocks 26 are fixedly connected to the bottom of the bottom cross rod 22, and the first triangular top blocks 25 are slidably connected to the second triangular top blocks 26. The five cross rods 22 are fixedly connected to each other through vertical rods and are arranged in a vertical direction. The brackets 27 are fixedly connected to the bottom inner wall of the box body 1, a chute is formed through one side of the brackets 27, and the horizontal sliding rod 24 is slidably connected inside the chute. The left and right movement of the horizontal sliding rod 24 is limited by setting the chute. The right end of the electric telescopic rod 28 is fixedly connected to the right bracket 27, and the left end of the electric telescopic rod 28 is fixedly connected to the bottom of the horizontal sliding rod 24 through a fixing block.

[0028] Working principle: When in use, the electric telescopic rod 28 drives the horizontal sliding rod 24 to move left and right. During the process of the horizontal sliding rod 24 moving left, the left first triangular top block 25 is driven to move left. During the process of the left first triangular top block 25 moving left, the left second triangular top block 26 is pushed upward. The upward movement of the left second triangular top block 26 drives the left cross rod 22 to move upward, and the upward movement of the left cross rod 22 drives the left scraping plate 23 to move upward. Similarly, when the horizontal sliding rod 24 moves right, the right scraping plate 23 is driven to move upward, and the left first triangular top block 25 is driven to move right. After the left second triangular top block 26 loses the support of the left first triangular top block 25, it drives the left scraping plate 23 to move downward under the action of gravity. In this way, the left and right scraping plates 23 move up and down reciprocally at the same time and defrost both sides of the inner wall of the box body 1, thus saving manpower.

[0029] Please refer to Figures 1-4, on the basis of the above embodiments, in another embodiment of the present utility model, a swing mechanism 3 is arranged inside the box body 1.

The front end of the rotating rod 31 is fixedly connected to the bottom end of a movable rod 32. A right side of the movable rod 32 is fixedly connected to an electric heater 33, and a left side of the movable rod 32 is fixedly connected to an electric refrigerator 34. The temperature inside the box body 1 is adjusted by setting the electric heater 33 and the electric refrigerator 34. The bottom end of the movable rod 32 is fixedly connected to a semi-toothed gear 36. A top of a horizontal sliding rod 24 is fixedly connected to a rack 35. The rack 35 meshes with the semi-toothed gear 36. The rotation of the semi-toothed gear 36 is driven by setting the rack 35. The bottom inner wall of the box body 1 is fixedly connected to a tabletop 4. A card slot is opened on a top of the tabletop 4. A box door 5 is arranged on a front surface of the box body 1. The test item to be subjected to the high and low temperature test is fixed by setting the card slot.

[0030] Working principle: During use, when the horizontal sliding rod 24 moves left and right, it drives the rack 35 to move left and right. The left and right movement of the rack 35 drives the semi-toothed gear 36 and the movable rod 32 to swing left and right. The left and right swing of the movable rod 32 drives the electric heater 33 and the electric refrigerator 34 to move left and right. Thus, the uniformity of the electric heater 33 and the electric refrigerator 34 when heating or cooling the inside of the box body 1 can be improved.

[0031] It should be noted that: in this embodiment, both the electric heater 33 and the electric refrigerator 34 are common devices in the prior art.
