[0003] When testing building materials, frost resistance testing is sometimes required. Frost resistance testing assesses a material's ability to maintain its original properties under repeated freeze-thaw cycles. This is crucial for ensuring the durability of buildings in cold regions or frost-prone environments. Frost resistance testing equipment is required when conducting frost resistance testing.
[0004] In the process of realizing this utility model, the inventors discovered the following problems with the existing technology: 1. When loading and unloading materials into some existing antifreeze testing equipment, manual labor is required to manually insert one's hand into the equipment to complete the relevant work process, which is time-consuming and laborious; 2. When using some existing antifreeze testing equipment, the sealing purpose is generally achieved by installing a single sealing ring on the door panel. However, the sealing effect of this single sealing ring is not good. Sometimes, in order to ensure the sealing effect as much as possible, it is necessary to insert sealing material into the gap between the door panel and the equipment box, which is time-consuming and laborious.

Detailed Implementation
[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figures 1 to 5 The present invention provides a technical solution: an antifreeze testing device that is easy to seal, including a testing component 1, a movable component 2 installed on the inner wall of the testing component 1, and a placement component 3 installed on the top of the movable component 2.
[0026] The testing assembly 1 includes a testing box 101. A cooling device 102 and a pressure relief valve 103 are installed on the top of the testing box 101. A U-shaped block 104 is installed on one side of the testing box 101. A door panel 105 is installed at the front end of the testing box 101 via a hinge. A frame 106 is installed on one side of the door panel 105. An insert block 107 is installed at the front end of the door panel 105.
[0027] The moving component 2 includes a track 201 and a geared motor 202. A gear 203 is installed at the output end of the geared motor 202. A T-shaped slide plate 204 is slidably installed on the inner wall of the track 201. A limit block 205 is installed on one side of the T-shaped slide plate 204. A support plate 206 is installed on the top of the T-shaped slide plate 204. A rack 207 is installed on the bottom of the support plate 206.
[0028] The storage component 3 includes a storage box 301, and a fixing block 302 is installed on the bottom of the storage box 301 and near the four corners.
[0029] In this embodiment, as Figure 2 As shown, the front end of the testing box 101 has an opening groove, and the top and bottom of the inner wall of the opening frame and one side of the frame 106 are all provided with sealing rings. When the door panel 105 is closed with the testing box 101, the frame 106 is inserted into the opening groove at the front end of the testing box 101. The sealing ring on the frame 106 contacts the rear end of the inner wall of the opening groove, and the sealing rings at the top and bottom of the inner wall of the opening groove contact the outer wall and inner wall of the frame 106, respectively. This can achieve triple sealing, improve the sealing effect, and prevent cold air inside the testing box 101 from leaking out through the gap between the testing box 101 and the door panel 105. At the same time, the testing box 101 can be sealed by simply closing the door panel 105, which improves the convenience of sealing.
[0030] In this embodiment, as Figure 2 As shown, both the top of the insert block 107 and the U-shaped block 104 are provided with circular holes. When the door panel 105 is closed with the detection box 101, the insert block 107 is inserted into the U-shaped block 104, and then the pin is inserted into the corresponding circular holes on the insert block 107 and the U-shaped block 104, which can improve the stability of the door panel 105 after it is closed with the detection box 101.
[0031] In this embodiment, as Figure 2 As shown, the front end of the support plate 206 is provided with a sealing strip, and the support plate 206 and the door plate 105 form a sealing structure through the sealing strip; when the door plate 105 is closed with the test box 101, the sealing strip contacts the door plate 105, which can prevent the cold air in the test box 101 from entering the lower space divided by the support plate 206 in the test box 101.
[0032] In this embodiment, as Figure 2 and Figure 3As shown, a reduction motor 202 is installed through the bottom of the testing box 101. A gear 203 meshes with a rack 207. A track 201 is installed on the bottom of the inner wall of the testing box 101. The track 201, the T-shaped slide plate 204, and the limiting block 205 are symmetrically distributed about the vertical center line of the support plate 206. When the reduction motor 202 is started, the gear 203 can drive the rack 207 to move back and forth, and at the same time drive the support plate 206 and the T-shaped slide plate 204 to move back and forth. When performing testing, the storage box 301 placed on top of the support plate 206 can be moved out of the testing box 101 for easy loading and unloading.
[0033] In this embodiment, as Figure 3 As shown, a circular hole is provided on the top of the support plate 206 near one side, and a pin is inserted into the circular hole. When the reduction motor 202 starts and drives the support plate 206 and the T-shaped slide plate 204 to move forward, the pin can limit the limit block 205, which can prevent the T-shaped slide plate 204 from falling off the track 201 and improve the stability of the equipment during use. When the pin is removed, the T-shaped slide plate 204, the limit block 205 and the support plate 206 can be removed from the equipment for subsequent cleaning or maintenance.
[0034] In this embodiment, as Figure 4 and Figure 5 As shown, the top of the support plate 206 has four circular holes with internal dimensions that match the external dimensions of the fixing blocks 302. When the placement component 3 is placed on top of the support plate 206, the four fixing blocks 302 are inserted into the corresponding circular holes on the top of the support plate 206, which can improve the stability of the installation of the placement component 3 and the support plate 206, thereby improving the stability of the equipment during use. The handle on the placement component 3 can be used to lift the placement component 3 directly upwards, making it easy to remove the placement component 3 and the test material inside the placement component 3 from the equipment after the test is completed, which is convenient for subsequent cleaning of the test material.
[0035] The method of use and advantages of this utility model: This easy-to-seal antifreeze testing device operates as follows:
[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, firstly, the reduction motor 202 is started, which drives the gear 203 to rotate, thereby moving the rack 207, T-shaped slide plate 204, support plate 206, and storage assembly 3 forward, so that most of the storage assembly 3 moves outside the detection box 101. Then, the building materials to be tested are placed inside the storage box 301. Next, the reduction motor 202 is started, driving the rack 207, T-shaped slide plate 204, support plate 206, and storage assembly 3 backward into the detection box 101. Then, the door panel 105 is closed with the detection box 101, and at the same time, the frame 106 is inserted into the slot at the front end of the detection box 101, and the insert block 107 is inserted into the U-shaped block 104. Then, the pin is inserted into the corresponding circular hole on the insert block 107 and the U-shaped block 104. Next, the refrigeration unit 102 is started. After the compressor in the refrigeration unit 102 starts, it draws low-temperature and low-pressure refrigerant gas from the evaporator and compresses it into high-temperature and high-pressure gas. The gas enters the condenser and is liquefied through heat exchange. Then, it is depressurized and cooled by the throttling valve (expansion valve) into a low-temperature and low-pressure liquid-gas mixture and enters the evaporator, thereby cooling the test chamber 101. The temperature sensor in the test chamber 101 senses the temperature change and starts and stops the refrigeration unit 102 to keep the temperature in the test chamber 101 at the preset test temperature. When the test is finished, the pins of the insertion block 107 and the U-shaped block 104 are pulled out. Then, the door panel 105 is opened and the geared motor 202 is started. The geared motor 202 drives the rack 207, the T-shaped slide plate 204, the support plate 206 and the storage assembly 3 to move forward.
