Technical Field

[0001] This utility model belongs to the field of circuit board testing technology, and in particular relates to a basket connection structure for a thermal shock test chamber. Background Technology

[0002] Thermal shock test chambers are essential testing equipment in the metal, plastic, rubber, and electronics industries. They are used to test the degree to which material structures or composite materials can withstand continuous high-temperature to low-temperature environments in an instant. They can detect chemical changes or physical damage to samples caused by thermal expansion and contraction in the shortest possible time. Thermal shock test chambers are required for the testing of finished circuit boards.

[0003] The lifting cylinder and the basket in the thermal shock test chamber are fixed together by bolts. However, when the basket is disassembled and maintained, the bolts need to be turned, which is slightly inconvenient. Therefore, a basket connection structure for the thermal shock test chamber is needed to allow for quick disassembly and assembly of the basket and the lifting cylinder, thereby facilitating subsequent maintenance and replacement of the basket and improving the convenience of subsequent use and maintenance.

[0010] The beneficial effects of this utility model are:

[0011] This invention uses a sliding rod to move a cylindrical block backward, while the sliding rod compresses a spring via a circular plate. The suspended basket frame is then fitted onto the surface of the lifting cylinder, with an L-shaped plate extending through the top of the suspended basket frame. The sliding rod is then released, allowing the spring's rebound force to drive the cylindrical block into the inner cavity of the circular hole via the circular plate and the sliding rod. This locks the L-shaped plate and the suspended basket frame together, enabling quick assembly and disassembly of the suspended basket and the lifting cylinder. This facilitates subsequent maintenance and replacement of the suspended basket, thereby improving the convenience of subsequent use and maintenance.

Example 2

[0023] Figure 1-4This invention illustrates a hanging basket connection structure for a thermal shock test chamber according to an embodiment of the present invention. The structure includes a test chamber body 1. The inner cavity of the test chamber body 1 is provided with a hot chamber 2 and a cold chamber 3. A lifting cylinder 4 is bolted to the inner wall of the test chamber body 1. A hanging basket frame 5 is provided in the inner cavities of the hot chamber 2 and the cold chamber 3. A cylindrical box 7 is fixedly connected to the top of the hanging basket frame 5. An L-shaped plate 8 is fixedly connected to the surface of the lifting cylinder 4. The top of the L-shaped plate 8 extends through to the top of the hanging basket frame 5. A square opening 9, adapted to the L-shaped plate 8, is provided on the surface of the hanging basket frame 5. A sliding rod 10 is slidably connected to the inner wall of the cylindrical box 7. A circular hole 11 is provided on the surface of the L-shaped plate 8. A cylindrical block 12 is fixedly connected to the end of the slide rod 10. The cylindrical block 12 is located in the inner cavity of the circular hole 11. The diameter of the cylindrical block 12 is adapted to the inner diameter of the circular hole 11. A rectangular opening 13 adapted to the slide rod 10 is opened on the top of the L-shaped plate 8. A circular plate 14 is fixedly connected to the surface of the slide rod 10. A spring 15 is fixedly connected between the surface of the circular plate 14 and the inner wall of the cylindrical box 7. A pressing block 16 is fixedly connected to the end of the slide rod 10. By setting the pressing block 16, the force-bearing area of ​​the end of the slide rod 10 is increased, avoiding finger pain when pressing the slide rod 10 directly, thereby improving the comfort of the user when pressing the slide rod 10.

[0024] Working principle: When using this utility model, the user presses the sliding rod 10 to move the cylindrical block 12 backward. At the same time, the sliding rod 10 drives the spring 15 to compress through the circular plate 14. Then, the suspended basket frame 5 is placed on the surface of the lifting cylinder 4. At this time, the L-shaped plate 8 extends through to the top of the suspended basket frame 5. During this process, the sliding rod 10 enters the inner cavity of the circular hole 11 through the rectangular opening 13. Then, the sliding rod 10 is released, so that the rebound force of the spring 15 drives the cylindrical block 12 into the inner cavity of the circular hole 11 through the circular plate 14 and the sliding rod 10. Then, the L-shaped plate 8... The circuit board 8 is locked to the basket frame 5. Then, the circuit board is placed in the inner cavity of the basket frame 5. Next, the lifting cylinder 4 drives the basket frame 5 to move vertically in the inner cavity of the test chamber 1. Then, the basket frame 5 drives the circuit board through the thermal shock test in the hot chamber 2 and the cold chamber 3. If it is necessary to disassemble the basket frame 5, the above steps can be followed. This realizes the quick disassembly and assembly between the basket and the lifting cylinder, which facilitates the subsequent maintenance and replacement of the basket and improves the convenience of subsequent use and maintenance.

[0025] In summary, this thermal shock test chamber uses a basket connection structure. By pressing the slide rod 10, the cylindrical block 12 moves backward. At the same time, the slide rod 10 compresses the spring 15 through the circular plate 14, and then the basket frame 5 is fitted onto the surface of the lifting cylinder 4. At this time, the L-shaped plate 8 extends through to the top of the basket frame 5. Then, the slide rod 10 is released, so that the rebound force of the spring 15 drives the cylindrical block 12 into the inner cavity of the circular hole 11 through the circular plate 14 and the slide rod 10. Subsequently, the L-shaped plate 8 and the basket frame 5 are locked together, which can achieve quick assembly and disassembly between the basket and the lifting cylinder, thereby facilitating subsequent maintenance and replacement of the basket and improving the convenience of subsequent use and maintenance.
