Description

Technical Field

[0001] This application relates to the field of coating testing equipment, and in particular to a coating aging resistance test chamber. Background Technology

[0002] Aging test chambers are a general term for equipment used in the environmental testing industry to conduct accelerated aging tests on materials under artificial climate conditions. They are widely used in the fields of electronics, automobiles, aerospace, plastics and rubber to evaluate the weather resistance, corrosion resistance and reliability of materials.

[0003] However, existing aging resistance test chambers have a relatively simple internal structure for storing samples to be tested. When in use, samples are generally placed directly into the chamber with a single storage structure, which cannot meet the storage needs of samples of different specifications or shapes. Utility Model Content

[0004] To address the aforementioned issues, this application provides a coating aging resistance test chamber.

[0005] The coating aging resistance test chamber provided in this application adopts the following technical solution: A coating aging resistance test chamber includes a test chamber body. The front of the test chamber body has a door and a control panel. A base is located at the bottom of the test chamber body. A support mechanism and a storage mechanism for placing samples are respectively provided on the base. The support mechanism includes an annular groove recessed downwards at the top of the base. A cross-shaped storage groove is formed inside the annular groove. A slider is slidably connected inside the storage groove. A horizontally placed spring is provided at one end of the slider, and the end of the spring away from the slider is connected to the end wall of the storage groove. Limiting blocks are provided on both sides of the slider. A limiting groove adapted to the limiting blocks is formed in the groove wall of the storage groove. The storage structure includes a support rod, a vertically arranged connecting rod hinged to one end of the support rod, and a top plate fixed to the top of the connecting rod for storing samples. The end of the support rod away from the connecting rod is hinged to the other end of the slider.

[0006] By adopting the above technical solution, the appropriate form can be adjusted according to the storage requirements of the sample.

[0007] Preferably, the length of the receiving groove is greater than the length of the limiting groove.

[0008] By adopting the above technical solution, it can be ensured that the slider can slide fully along the storage groove without detaching.

[0009] Preferably, the length of the limiting block is the same as the length of the slider, and the height of the slider is less than the height of the storage groove.

[0010] By adopting the above technical solution, the top plate can be retracted into the storage slot, making the upper surface of the top plate flush with the upper surface of the base, which is convenient for storing samples of different specifications.

[0011] Preferably, the top plate has a circular structure, and the diameter of the top plate is smaller than the diameter of the annular groove. The outer circumference of the top plate is hinged with multiple hooks for suspending samples.

[0012] By adopting the above technical solution, it is convenient to meet the suspension requirements of samples to be tested that need to be suspended.

[0013] Preferably, the base has a through hole at its center for the connecting rod to pass through, and the through hole is located at the center of the cross-shaped storage groove.

[0014] By adopting the above technical solution, it can be ensured that the connecting rod can pass through the through hole and be quickly fixed by the fixing pin.

[0015] Preferably, the length of the connecting rod is greater than the depth of the through hole, the lower end of the connecting rod is provided with a fixing hole, the bottom end of the base is provided with an arc-shaped side lug, and a fixing pin is movably inserted into the outer wall of the side lug.

[0016] By adopting the above technical solution, when the top plate is stored in the annular groove, the lower section of the connecting rod passes through the through hole and the position of the fixing hole corresponds to the fixing pin. At this time, the fixing pin is inserted into the fixing hole to fix the connecting rod, thereby facilitating the fixing of the top plate.

[0017] Preferably, the top of the slider is provided with an insertion hole, and the bottom of the storage groove is provided with a plurality of first positioning holes corresponding to the insertion hole.

[0018] By adopting the above technical solution, the slider can be fixed by inserting the pin into the through hole and the first positioning hole, thereby ensuring that the support rod and the connecting rod support the top plate.

[0019] In summary, this application includes at least one of the following beneficial technical effects: This application, through the design of annular grooves and storage grooves, allows for the placement of samples requiring flat placement. The upper surface of the top plate and the upper section of the base are aligned on the same horizontal plane, forming a storage platform. When the sample needs to be suspended, multiple sliders slide towards the center under the force of springs, causing the connecting rod to move upwards under the push of the support rod until the top plate is above the base. At this point, the hook can be in a vertical position for suspending the sample. When suspending the sample is not required, simply press the top plate downwards to move it into the annular groove, where it is then fixed by a fixing pin. This allows the invention to meet the storage needs of samples of different specifications or shapes. Attached Figure Description

Detailed Implementation

[0022] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0023] This application discloses a coating aging resistance test chamber.

[0024] Reference Figure 1 , Figure 2 and Figure 3 A coating aging test chamber includes a test chamber body 1. The front of the test chamber body 1 is provided with a door 2 and a control panel 3. The temperature and humidity control methods and light conditions required for aging test chambers for coatings are conventional technical means in the field. Therefore, this application will not elaborate further on the prior art in this part. The bottom of the test chamber body 1 is provided with a base 4. The base 4 is provided with a support mechanism and a storage mechanism for placing samples. Reference Figure 3 The support mechanism includes an annular groove 46 formed by a downward recess at the top of the base 4. The annular groove 46 has a cross-shaped storage groove 41 inside. A slider 42 is slidably connected inside the storage groove 41. A horizontally placed spring 43 is provided at one end of the slider 42, and the end of the spring 43 away from the slider 42 is connected to the end wall of the storage groove 41. Limiting blocks 44 are provided on both sides of the slider 42. The groove wall of the storage groove 41 has a limiting groove 45 that matches the limiting block 44. The groove length of the storage groove 41 is greater than the groove length of the limiting groove 45, so as to ensure that the slider 42 can slide fully along the storage groove 41 without detaching. The storage structure includes a support rod 5, a vertically arranged connecting rod 6 hinged to one end of the support rod 5, and a top plate 7 fixed to the top of the connecting rod 6 for storing samples. The end of the support rod 5 away from the connecting rod 6 is hinged to the other end of the slider 42. The top plate 7 can be raised or stored in the annular groove 46 according to the sample storage requirements.

[0025] Reference Figure 2 and Figure 3 The length of the limiting block 44 is the same as the length of the slider 42, and the height of the slider 42 is less than the height of the storage groove 41, so that the slider 42 can slide fully along the storage groove 41 without detaching.

[0026] Reference Figure 4 The top plate 7 has a circular structure, and the diameter of the top plate 7 is smaller than the diameter of the annular groove 46. The outer circumference of the top plate 7 is hinged with multiple hooks 8 for suspending samples, which facilitates the storage of samples of different sizes.

[0027] Reference Figure 1 and Figure 2 The base 4 has a through hole 10 for the connecting rod 6 to pass through, and the through hole 10 is located at the center of the storage groove 41 which has a cross-shaped structure.

[0028] Reference Figure 3 The length of the connecting rod 6 is greater than the depth of the through hole 10. The lower end of the connecting rod 6 is provided with a fixing hole 9. The bottom end of the base 4 is provided with an arc-shaped side ear 11, and a fixing pin 12 is movably inserted into the outer wall of the side ear 11. The connecting rod 6 is fixed by inserting the fixing pin 12 into the fixing hole 9, which facilitates the fixing of the top plate 7.

[0029] Reference Figure 3 The top of the slider 42 is also provided with an insertion hole, and the bottom of the storage groove 41 is provided with multiple first positioning holes 47 corresponding to the insertion hole. By inserting the pin into the through hole and the first positioning hole 47, the slider 42 can be fixed, thereby ensuring that the support rod 5 and the connecting rod 6 support the top plate 7.

[0030] The implementation principle of a coating aging resistance test chamber according to an embodiment of this application is as follows: During use, through the annular groove 46 and the storage groove 41, when a sample to be tested requires horizontal placement, the lower section of the connecting rod 6 passes through the through hole 10 when the top plate 7 is stored in the annular groove 46, aligning the position of the fixing hole 9 with the fixing pin 12. The fixing pin 12 is then inserted into the fixing hole to fix the connecting rod 6, thereby facilitating the fixing of the top plate 7. This ensures that the upper surface of the top plate 7 and the upper surface of the base 4 are on the same horizontal plane, forming a storage platform. When it is necessary to suspend the sample to be tested, simply align the fixing pin 12 with the base 4. Pin 12 is removed from the fixing hole 9. The top plate 7 is guided upward and gently lifted. Under the elastic force of spring 43, multiple sliders 42 slide towards the center. The sliders 42 drive the support rod 5 to change the angle between it and the base 4, so that the connecting rod 6 moves upward under the push of the support rod 5 until the top plate 7 moves above the base 4. At this time, the hook 8 can be in a vertical state, which can then be used to suspend the sample to be tested. When it is not necessary to suspend the sample to be tested, simply press the top plate 7 downward to move it into the annular groove 46, and then fix it by fixing pin 12. Thus, this utility model can meet the storage needs of samples to be tested of different specifications or shapes.

[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
