Description

Technical Field

[0001] This utility model relates to the field of test chamber technology, specifically to a shockproof and noise-reducing structure for a test chamber refrigeration structure. Background Technology

[0002] Test chambers have wide applications in many fields such as scientific research and industrial production, and the stable operation of their refrigeration structure plays a decisive role in the accuracy of test results. During the operation of the test chamber, components such as the compressor and fan in the refrigeration structure will generate significant vibration and noise.

[0003] To reduce the interference of vibration and noise on the test, the common practice is to install a shock-absorbing structure inside the test chamber and fix the cooling structure to the outside of the shock-absorbing structure with screws and nuts.

[0004] However, this traditional installation method has obvious drawbacks. Because the refrigeration structure continuously vibrates during long-term operation, and the existing installation method lacks an effective locking structure, the screw and nut will gradually loosen and fall off after prolonged use. Once the screw and nut loosen, not only will the vibration and noise reduction effect of the refrigeration structure be greatly reduced, and the vibration and noise will be aggravated, affecting the accuracy of the test results, but it may also cause the refrigeration structure to shift or even fall off, damaging other components inside the test chamber, causing equipment failure, increasing maintenance costs and downtime, and seriously affecting the progress of scientific research and the continuity of industrial production.

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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0031] Please see Figure 1-3 As shown, this utility model is a shockproof and noise-reducing structure for a test chamber refrigeration structure, comprising:

[0032] Box 11;

[0033] The shock-absorbing component includes a base plate 21 and shock-absorbing springs 22, with the shock-absorbing springs 22 distributed on the top of the base plate 21;

[0034] The locking component includes a cooling plate 31, a vertical rod 32, a nut ring 33, a plug rod 34, a locking frame 35, a pressure plate 37, and a telescopic spring 39. The cooling plate 31 is located above a plurality of shock-absorbing springs 22. The telescopic spring 39 is wrapped around the outer surface of the vertical rod 32. The pressure plate 37 is movably connected to the outer surface of the vertical rod 32. The plug rod 34 is connected to the top of the cooling plate 31. The nut ring 33 is threaded to the outside of the plug rod 34. The locking frame 35 is fixed to one end of the pressure plate 37 and locked to the outer surface of the nut ring 33.

[0035] The locking frame 35 is driven to snap and fix to the outside of the nut ring 33 by the buffering force generated by the telescopic spring 39, forming a solid locking structure. Compared with the traditional fixing method that only relies on screws and nuts, this design can effectively resist the influence of continuous vibration during the operation of the refrigeration structure, and prevent the screw and nut from loosening and falling off at the source. Even under long-term high-frequency vibration environment, the locking frame 35 and the nut ring 33 are tightly matched and always maintain a stable fixed state, ensuring the stable installation of the refrigeration structure and providing a reliable guarantee for the stable operation of the test chamber.

[0036] A top plate 23 is fixed to the top of several of the shock-absorbing springs 22, and the upright 32 is set on the top of the top plate 23.

[0037] A support frame 24 is provided on the top of the base plate 21, and the support frame 24 surrounds the outer surface of the shock-absorbing spring 22;

[0038] The shock-absorbing spring 22 provides shock protection for the cooling plate 31 during operation.

[0039] A limiting plate 36 is fixed to the top of the upright 32, and a rotating ring 38 is provided at the top and bottom of the pressure plate 37. The rotating ring 38 is rotatably connected to the outer surface of the upright 32.

[0040] The angle of the pressure plate 37 can be adjusted by rotating the rotating ring 38 outside the upright 32.

[0041] Working principle: When installing the refrigeration structure, the refrigeration plate 31 is placed on top of the top plate 23. The shock-absorbing spring 22 set below the top plate 23 begins to function. The shock-absorbing spring 22 absorbs the vibration energy generated by the refrigeration plate 31 during operation through its own elastic deformation, converting the vibration into the elastic potential energy of the spring, and then slowly releasing it, thereby effectively reducing the transmission of vibration, achieving a good anti-vibration effect, and reducing the impact of vibration on the overall structure of the test chamber and the internal test samples.

[0042] When it is necessary to fix the refrigeration structure, the nut ring 33 is fitted onto the outside of the insertion rod 34 and tightened to complete the initial fixation. At this time, since the rotating ring 38 can rotate freely outside the upright rod 32, the operator can easily adjust the position of the rotating ring 38 so that the locking frame 35 on the rotating ring 38 is precisely aligned with the nut ring 33. When the two are aligned, the buffering force generated by the telescopic spring 39 begins to play its role, pushing the locking frame 35 to move towards the nut ring 33 and finally locking it onto the outside of the nut ring 33. The buffering force of the telescopic spring 39 can adapt to the vibration of the refrigeration structure during operation. When vibration occurs, through the compression and extension of the spring, the locking frame 35 and the nut ring 33 are always kept in a tight engagement state, thereby providing a secondary locking fixation for the nut ring 33, forming a double guarantee. This design effectively resists the problem of loosening and falling off of the screw and nut caused by long-term vibration of the refrigeration structure, ensuring that the refrigeration structure is stably installed in the test chamber, ensuring the stable operation of the refrigeration structure of the test chamber, maintaining good anti-vibration and noise reduction effects, and providing reliable support for the accuracy of the test.

[0043] Please see Figure 1 , Figure 4 As shown, this embodiment, based on the above embodiment, further includes:

[0044] The assembly component includes a sound insulation panel 41, a sound insulation panel 42, a sound insulation panel 43, a connecting strip 44, and a connecting groove 45. The sound insulation panel 41 is attached to both ends of the inner surface of the housing 11, the sound insulation panel 42 is attached to the top of the inner surface of the housing 11, the sound insulation panel 43 is attached to one side of the inner surface of the housing 11, the connecting strip 44 is provided at both ends of the outer surface of the sound insulation panel 42, and the connecting groove 45 is opened at the upper and lower parts of the end of the sound insulation panel 41, and the connecting strip 44 is snapped into the inside of the connecting groove 45.

[0045] Sound insulation panel 1 (41), sound insulation panel 2 (42), and sound insulation panel 3 (43) are installed inside the enclosure 11 by splicing, which facilitates installation and disassembly.

[0046] The upper and lower parts of one side of the outer surface of the sound insulation panel 41 are provided with fixing rods 46, and the two ends of the sound insulation panel 43 are provided with fixing holes 48. The fixing rods 46 are inserted into the fixing holes 48, and the outer surface of the fixing rods 46 is threaded with fixing rings 47.

[0047] The mating strip 44 is fixed to the mating groove 45, the fixing rod 46 is inserted into the fixing hole 48, and the fixing ring 47 is fastened to the outside of the fixing rod 46, so that the sound insulation panel 1 41, the sound insulation panel 2 42 and the sound insulation panel 3 43 are assembled together and then embedded in the inside of the box 11.

[0048] A baffle 52 is movably connected through one side of the outer surface of the box 11. A limit plate 51 is provided at one end of the baffle 52, and a rubber block 53 is glued to the other end of the baffle 52.

[0049] After the sound insulation panel 1 41, sound insulation panel 2 42 and sound insulation panel 3 43 are assembled together and embedded inside the housing 11, the limiting plate 51 is pushed so that the baffle 52 blocks the outside of the sound insulation panel 1. By squeezing the rubber block 53, the rubber block 53 is fixed to one end of the sound insulation panel 1 41.

[0050] The working principle involves the coordinated action of multiple components to achieve stable installation and positioning of the sound insulation panels. First, the sound insulation panels are assembled. When combining sound insulation panel 1 (41), sound insulation panel 2 (42), and sound insulation panel 3 (43), the mating strips 44 on the edges of the sound insulation panels are precisely aligned with the mating grooves 45 of the adjacent sound insulation panels. The initial splicing and positioning are completed by utilizing the fitting structure of the mating strips 44 and the mating grooves 45. Next, the fixing rod 46 is inserted into the fixing hole 48 formed after the mating. Then, the fixing ring 47 is tightened on the outside of the fixing rod 46. Through the binding force of the fixing ring 47 on the fixing rod 46, the three sound insulation panels are tightly connected into a whole, ensuring that the spliced ​​sound insulation panel structure is stable and has good integrity and strength.

[0051] After assembly, the assembled sound insulation panel is embedded inside the chamber 11 to provide a sound barrier for the test chamber. To further secure the sound insulation panel 41, the limiting plate 51 is pushed, causing the limiting plate 51 to move the baffle 52 to the outside of the sound insulation panel 41, thus blocking and limiting the sound insulation panel 41. During this process, the baffle 52 compresses the rubber block 53. Utilizing the good elasticity and deformation recovery ability of the rubber block 53, it deforms under force and snaps into one end of the sound insulation panel 41. After the rubber block 53 is snapped in, it firmly presses against the sound insulation panel 41 with its own elastic recovery force, thereby achieving reliable fixation of the sound insulation panel 41 and preventing it from shifting or loosening due to vibration or other factors during the operation of the test chamber. This ensures that the sound insulation structure continuously and stably performs its sound insulation and noise reduction function, creating a quiet internal environment for the test chamber.
