Description

Technical Field

[0001] This utility model relates to the technical field of hot and cold water impact test chambers, specifically a self-opening hot and cold water impact test chamber. Background Technology

[0002] Thermal shock testing, also known as temperature shock testing or high and low temperature shock testing, is mainly used to assess a product's adaptability to rapid changes in ambient temperature. This test is essential in the qualification testing of equipment design and routine testing during the mass production stage, and is sometimes also used for environmental stress screening testing.

[0003] A hot and cold water shock test chamber is a device used to test the tolerance of materials, components, or products to rapid temperature changes. It is the specific testing equipment used to perform the aforementioned tests; it can rapidly switch from high to low temperatures in a short time, simulating extreme temperature environments to evaluate the performance and stability of samples under rapid temperature changes.

[0004] Traditional hot and cold water impact test chambers typically include a high-temperature chamber and a low-temperature chamber. In actual laboratory settings, the product is first placed in the low-temperature chamber for a low-temperature impact test, followed by a high-temperature impact test in the high-temperature chamber. However, traditional hot and cold water impact test chambers often have an open-structure design on the upper surface of the chamber. Therefore, during actual use, the low-temperature or high-temperature liquid inside the chamber exchanges heat with the ambient air, which increases the rate of temperature loss of the liquid inside the chamber. That is, the high-temperature liquid cools down while the low-temperature liquid heats up, thus affecting the final impact test results and presenting certain limitations. To address this, this invention proposes a self-opening hot and cold water impact test chamber that can seal and automatically open the upper part of the chamber. Utility Model Content

[0005] The purpose of this invention is to provide a self-opening hot and cold water impact test chamber to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a self-opening hot and cold water impact test chamber, comprising a main chamber, a hot and cold cabinet at the bottom of the main chamber, an impact chamber above the hot and cold cabinet and located inside the main chamber, a high-temperature barrel fixedly installed on one side of the hot and cold cabinet, a low-temperature barrel fixedly installed on the other side of the high-temperature barrel, a rotating shaft on the outer side of both the high-temperature barrel and the low-temperature barrel, a rotating block sleeved on the rotating shaft, the rotating block fixedly connected to the rotating shaft, a barrel cover fixedly installed on the outer surface of the rotating block, one end of the rotating shaft extending through the impact chamber, a driving cylinder fixedly installed on the outer side wall of the impact chamber, a connecting block rotatably installed at the bottom end of the output rod of the driving cylinder, and the other end of the connecting block fixedly sleeved on the outside of the rotating shaft.

[0007] Preferably, lifting cylinders are fixedly installed on both sides of the lower surface of the bottom end of the impact chamber. The output end of the lifting cylinder is movably connected to a pneumatic rod, and the top ends of the two pneumatic rods, located inside the impact chamber, are fixedly installed with mounting bases.

The output rod of the displacement cylinder is fixedly connected to the outer wall of the upper sliding seat.

[0009] Preferably, the lower surface of the bottom end of the upper slide is fixedly mounted with a basket by bolts.

[0010] Preferably, water injection pipes are fixedly installed on the back exterior of both the high-temperature barrel and the low-temperature barrel, and drain pipes are fixedly installed on the bottom outer wall of both the high-temperature barrel and the low-temperature barrel.

[0011] Preferably, the outer surface of the impact chamber is provided with two sealed doors, which are hinged to the main body via hinges, and each sealed door has a viewing window.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention features an automatically opening and closing lid structure at the opening of a high-low temperature tank. The lid can be used to cover the opening of the tank, effectively reducing the heat exchange between the internal liquid and the outside air. This reduces and mitigates the rate of heat loss, effectively slowing down the cooling and heating rates of high-temperature or low-temperature liquids, ensuring the temperature accuracy of hot and cold water shock tests, reducing temperature errors, and demonstrating good practicality and improved test precision.

[0014] Meanwhile, the lid can be used in conjunction with the connecting rod and rotating shaft under the action of the cylinder drive structure, so as to automatically open and close the barrel. When the barrel is not in use, the top of the barrel can be sealed, thereby reducing and mitigating the heat exchange rate of the liquid and ensuring the accuracy of the liquid inside the barrel. When the barrel is in use, it has the practical effect of automatic opening. The structure is more convenient to use, with a self-opening practical effect, requiring no manual operation, making it more convenient to use. Moreover, the overall structure is simple, with low manufacturing and maintenance costs, and better practicality.

[0015] Meanwhile, the lifting and displacement of the basket in this utility model's hot and cold water impact test chamber can be completed automatically. The staff only needs to put the test product in and take it out. The machine has a high degree of automation, excellent performance, and is more convenient to use. Attached Figure Description

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Please see Figure 1-4 This utility model provides an embodiment of a self-opening hot and cold water impact test chamber, comprising a main body 1, a hot and cold cabinet 2 at the bottom of the main body 1, an impact chamber 3 above the hot and cold cabinet 2 and located inside the main body 1, a high-temperature barrel 4 fixedly installed on one side of the inside of the hot and cold cabinet 2, and a low-temperature barrel 15 fixedly installed on the other side of the high-temperature barrel 4. A rotating shaft 5 is provided on the outer side of both the high-temperature barrel 4 and the low-temperature barrel 15, and a rotating block 6 is sleeved on the rotating shaft 5. The rotating block 6 is fixedly connected to the rotating shaft 5, and a barrel cover 7 is fixedly installed on the outer surface of the rotating block 6. The barrel cover 7 is used to cover the port of the high and low temperature barrels, thereby effectively reducing the heat exchange effect between the internal liquid and the outside air, thereby effectively reducing and mitigating the heat loss rate, effectively reducing the cooling and heating rate of the high-temperature liquid or the low-temperature liquid, ensuring the temperature accuracy of the hot and cold water impact test, reducing temperature error, having good practicality, and improving test accuracy.

[0025] In order to facilitate the automatic opening and closing of the lid 7, one end of the rotating shaft 5 extends out of the impact chamber 3. A drive cylinder 8 is fixedly installed on the outer side wall of the impact chamber 3. A connecting block 9 is rotatably installed at the bottom of the output rod of the drive cylinder 8. The other end of the connecting block 9 is fixedly sleeved on the outside of the rotating shaft 5.

[0026] This structural design allows the output rod to extend and retract via the drive cylinder 8. When the output rod extends, it drives the rotating shaft 5 to rotate counterclockwise via the connecting block 9. At the same time, the lid 7 rotates counterclockwise, thus covering the top of the bucket.

[0027] When the output rod of the drive cylinder 8 retracts, its rod body drives the rotating shaft 5 to rotate clockwise via the connecting block 9. At this time, the bucket lid 7 can rotate clockwise synchronously under the action of the rotating shaft 5. Thus, the top of the bucket can be opened by the clockwise rotation of the bucket lid 7. The specific opening and closing states are as shown in the attached instruction manual. Figure 3 As shown;

[0028] This self-opening hot and cold water impact tank features a lid 7 that, driven by a cylinder, works in conjunction with a connecting rod and a rotating shaft to automatically open and close the tank. When not in use, the top of the tank can be sealed to reduce and mitigate the heat exchange rate of the liquid, ensuring the accuracy of the liquid's internal flow. The tank also features an automatic opening mechanism, making it more convenient to use. It requires no manual operation, is simple in structure, has low manufacturing and maintenance costs, and is highly practical.

[0029] In this embodiment, in order to ensure the normal hot and cold water impact conversion effect, lifting cylinders 10 are fixedly installed on both sides of the lower surface of the bottom end of the impact chamber 3. The output end of the lifting cylinder 10 is connected to a pneumatic rod, and the top of the two pneumatic rods and inside the impact chamber 3 are fixedly installed with a fixed seat 11.

[0030] Furthermore, a connecting horizontal plate 12 is fixedly installed between the two fixed seats 11, and an upper slide block 13 is slidably connected to the upper surface of the connecting horizontal plate 12. The output rod of the displacement cylinder is fixedly connected to the outer wall of the upper slide block 13, and a hanging basket 14 is fixedly installed on the lower surface of the bottom end of the upper slide block 13 by bolts.

[0031] This structural design allows the basket 14 to support and place products that need to undergo hot and cold water impact tests. The lifting cylinder 10 can drive the pneumatic rod to extend and retract. When the pneumatic rod extends and retracts, it will drive the basket 14 on the connecting horizontal plate 12 to move up and down through the fixed seat 11. This allows the basket 14 to be lowered into the test barrel or driven to rise and detach from the barrel, completing the automatic lifting and unloading work after impact.

[0032] Meanwhile, the displacement cylinder can drive the upper slide 13 and the basket 14 to make linear left and right displacements through its output rod. In actual use, the left and right displacement of the basket 14 can drive the position of the barrel to change, so as to achieve the actual use effect of left and right cold and heat shock conversion.

[0033] In this embodiment, in order to facilitate the water injection and drainage of the high temperature cylinder 4 and the low temperature cylinder 15, water injection pipes 16 are fixedly installed on the back exterior of the high temperature cylinder 4 and the low temperature cylinder 15, and drain pipes 17 are fixedly installed on the bottom outer wall of the high temperature cylinder 4 and the low temperature cylinder 15.

[0034] Thus, the low-temperature liquid and high-temperature liquid used for the test can be injected into the high-temperature tank 4 and the low-temperature tank 15 respectively through the water injection pipe 6, ensuring the normal thermal shock liquid storage operation.

[0035] The drain pipe 17 can be used to drain the high and low temperature liquids inside the high temperature tank 4 and the low temperature tank 15 respectively.

[0036] In this embodiment, in order to improve the sealing performance of the impact chamber 3 during the test, two sealing doors 18 are provided on the outer surface of the impact chamber 3. The two sealing doors 18 are hinged to the main body 1. A viewing window is provided on the sealing door 18, which allows for easy and intuitive observation of the test conditions inside.

[0037] Working principle: When in use, this utility model can inject high-temperature liquid and low-temperature liquid for testing into the high-temperature tank 4 and the low-temperature tank 15 respectively through the water injection pipe 16.

[0038] Please refer to the instruction manual for details. Figure 3 As shown, after the liquid injection is completed, the product that needs to be subjected to hot and cold water shock test can be placed into the basket 14. At this time, the lifting cylinder 10 can be operated. When the lifting cylinder 10 is working, it drives the air pressure rod at the top of its end to retract. The retracted air pressure rod can drive the basket 14 to descend as a whole through the fixed seat 11 and the connecting horizontal plate 12. When the basket 14 descends, it will be placed in the low temperature tank 15 below, so that the low temperature liquid in the low temperature tank 15 can be used to conduct a low temperature shock test on the product inside the basket 14.

[0039] After the low-temperature impact test is completed, the pneumatic rod can be extended by the lifting cylinder 10. The extended pneumatic rod can move the basket 14 upward, so that the basket 14 can be lifted out of the low-temperature barrel 15.

[0040] After being lifted out, the output rod of the displacement cylinder can be extended by driving the displacement cylinder to extend. The extended output rod of the displacement cylinder can push the upper slide 13 at the top to move from right to left. In this way, the movement of the upper slide 13 drives the lower basket 14 to move.

[0041] After displacement, the basket 14 is placed directly above the high-temperature barrel 4. The barrel cover 7 can be driven to rotate counterclockwise by the drive cylinder 8 set on one side of the high-temperature barrel 4, and the barrel cover 7 on the high-temperature barrel 4 will open automatically.

[0042] Then the lifting cylinder 10 drives the basket 14 to descend again through the pneumatic rod, so that the basket 14 can be placed in the high temperature liquid inside the high temperature barrel 4, thereby automatically completing the high and low temperature liquid impact test of the product and testing the specific material properties of the product in high and low temperature environments.

[0043] After the high-temperature impact is completed, the lifting cylinder 10 drives the basket 14 to rise, and all structures are reset. Then the tested product can be taken out.

[0044] This utility model features a lid 7 that can be used to cover the port of the high and low temperature tank, thereby effectively reducing the heat exchange between the internal liquid and the outside air. This effectively reduces and mitigates the rate of heat loss, effectively reducing the cooling and heating rates of high-temperature or low-temperature liquids, ensuring the temperature accuracy of the hot and cold water shock test, reducing temperature errors, and demonstrating good practicality and improving test accuracy.

[0045] Meanwhile, the lid 7 can be used in conjunction with the connecting rod and rotating shaft under the action of the cylinder drive structure, so as to automatically open and close the barrel. When the barrel is not in use, the top of the barrel can be covered and sealed, thereby reducing and mitigating the heat exchange rate of the liquid and ensuring the accuracy of the liquid inside the barrel. When the barrel is in use, it has the actual effect of automatic opening. The structure is more convenient to use, with a self-opening effect, requiring no manual operation, making it more convenient to use. Moreover, the overall structure is simple, with low manufacturing and maintenance costs, and better practicality.

[0046] Meanwhile, the lifting and displacement of the basket in this utility model's hot and cold water impact test chamber can be completed automatically. The staff only needs to put the test product in and take it out. The machine has a high degree of automation, excellent performance, and is more convenient to use.

[0047] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
