[0002] Thermal shock testing machine is a necessary testing equipment for metal, plastic, rubber, electronic and other material industries. It is used to test the material structure or composite material to see how much it can endure in a continuous environment of extremely high and low temperatures in an instant, and to detect chemical changes or physical damage caused by thermal expansion and contraction of the sample in the shortest time. It is divided into two-compartment and three-compartment types, the difference lies in the different test methods and internal structures.

[0003] Based on the above, the inventors have found the following problems: most of the sample racks in current hot and cold shock testing equipment are divided into upper and lower sides, and the middle placement plate is fixedly installed in the sample rack. When the size of the placed sample is too large, the traditional sample rack placement plate is inconvenient to adjust, which makes the sample placement too difficult and has certain limitations.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an adjustable hot and cold shock test equipment is provided, in order to achieve a more practical purpose. Utility Model Content

[0024] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0025] Example:

[0026] As attached Figure 1 To Attachment Figure 5 As shown:

[0027] The utility model provides an adjustable hot and cold shock test device, comprising a box body 1, a cabinet door 2 is installed on one side of the box body 1 through a rotating shaft, an electric cylinder 3 is installed on the top of the box body 1, a fixing plate 4 is installed in the box body 1, the top of the fixing plate 4 is a cold liquid storage tank 5, and the bottom of the fixing plate 4 is a hot liquid storage tank 6, a groove 7 is opened inside the fixing plate 4, a sample rack 8 is slidably installed in the groove 7, mounting plates 9 are installed on the top and bottom of the sample rack 8, the mounting plate 9 is larger than the size of the groove 7, and a bayonet assembly is installed in the sample rack 8.

[0028] The output end of the electric cylinder 3 passes through the top of the box body 1 and is connected to the top of the mounting plate 9 .

[0029] Among them, the pin assembly includes a plurality of slide grooves 10 opened on both sides of the sample rack 8, and a placement plate 11 is installed in the slide groove 10. The placement plate 11 is slidably connected to the slide groove 10. Through the coordinated use of the slide groove 10 and the placement plate 11, when the size of the placed sample is too large, the placement plate 11 can be pulled out, a suitable position can be selected, and then the placement plate 11 can be placed in the slide groove 10. At the same time, multiple placement plates 11 can be placed and tests can be carried out at the same time. Through the above design, work efficiency is improved, friction is reduced, space is reasonably used, and the problem of difficulty in placing the sample due to the large size is reduced.

[0030] Among them, a group of chambers 12 are opened on the outward side of the placement plate 11, and a limit plate 13 is installed in the chamber 12. A spring 14 is connected to one side of the limit plate 13, and a mounting block 15 is installed on the other side of the limit plate 13. A fixing block 16 is installed on the outward side of the limit plate 13. Mounting holes 17 are opened on both sides of the box body 1, and the mounting blocks 15 are connected with the mounting holes 17 by snapping. Through the coordinated use of the limit plate 13, the spring 14, the mounting block 15, the mounting hole 17, the fixing block 16 and the straight groove 18, in order to prevent the sample rack 8 from being placed when moving. The placement plate 11 slides off, causing a waste of resources. Pull the fixing block 16 to one side, put the placement plate 11 into the appropriate slide groove 10, loosen the fixing block 16, and under the expansion and contraction of the spring 14, the mounting block 15 is snapped into the mounting hole 17 to complete the fixation. When the placed samples are of different sizes, pull the fixing block 16 to disengage the mounting block 15 from the mounting hole 17, select the appropriate slide groove 10, repeat the above operation, and complete the fixation. Through the above design, the practicality is greatly improved, and the placement plate 11 is prevented from sliding off when the sample rack 8 is moved, which is beneficial to saving resources and also saves human resources.

[0031] A straight groove 18 is formed on an outward side of the placement plate 11 , and the straight groove 18 is slidably connected to the fixing block 16 .

[0032] Among them, a sealing strip 19 is provided on one side of the joint between the mounting plate 9 and the fixing plate 4. The sealing strip 19 is provided to help maintain the sealing performance of the thermal shock test, and can also reduce heat conduction and provide a thermal insulation effect.

[0033] A handle 20 is installed on the outward side of the cabinet door 2 .

[0034] The specific usage and function of this embodiment are as follows:

[0035] During the use of the utility model, the integrity of the device is first confirmed. The sample is first placed on the placement plate 11. Since the sample rack 8 has the same size as the cold liquid storage tank 5 and the hot liquid storage tank 6, the cold and hot shock tests can be carried out respectively. When the size of the placed sample is too large, the placement plate 11 is pulled out, and a suitable position is selected, and then the placement plate 11 is placed in the slide 10. At the same time, multiple placement plates 11 can be placed and tested at the same time. Since the placement plate 11 slides when the sample rack 8 moves, it will cause a waste of resources. The staff pulls the fixing block 16 to one side, puts the placement plate 11 into the appropriate slide 10, and releases the fixing block 16. Under the expansion and contraction of the spring 14, the mounting block 15 is snapped into the mounting hole 17 to complete the fixation. When the placed samples are of different sizes, When the mounting block 15 is pulled out of the mounting hole 17, a suitable slide groove 10 is selected, and the above operation is repeated to complete the fixing. When the fixing is completed, the cabinet door 2 is closed, and a cold shock test is first performed. After the cold shock test is completed, the electric cylinder 3 is started to drive the sample rack 8 to move to the hot liquid storage tank 6 to perform a thermal shock test. Since a sealing strip 19 is provided on one side of the mounting plate 9, it effectively prevents the energy of the cold liquid storage tank 5 and the hot liquid storage tank 6 from mixing, resulting in inaccurate impact test. Through the above design, work efficiency is improved, friction is reduced, space is reasonably used, and the problem of difficulty in placing the sample due to the large size of the sample is reduced. The practicability is greatly improved, and the placement plate 11 of the sample rack 8 is prevented from slipping when moving, which is beneficial to saving resources and also saving human resources.
