Description

Technical Field

[0001] The utility model relates to the technical field of anechoic chambers, in particular to an anechoic chamber for noise testing. Background Art

[0002] An anechoic chamber, also known as a silent room or soundproof room, is a specially designed space used to reduce or eliminate the propagation of sound, thereby creating an environment with extremely low noise levels. It is commonly used in a variety of occasions such as acoustic testing, scientific research, audio equipment testing, hospital equipment testing, and industrial manufacturing sites.

[0003] Before using the existing anechoic chamber, most of the walls and ceilings that need to be used need to be spliced ​​together. However, in the prior art, expansion screws are mostly used for splicing. Although they have a good fixing effect, the overall operation process is relatively cumbersome, which affects the work efficiency of the staff. Utility Model Content

[0006] Preferably, first sliding grooves are provided on both sides of the interior of the sliding sleeve, first sliding blocks are installed on both sides of the sliding rod, and the interior of the first sliding groove is slidably connected to the first sliding block.

[0007] Preferably, two elastic sheets are installed on a side of the sliding sleeve away from the first wall, and one end of the elastic sheet close to the push-pull plate is fixedly connected to the push-pull plate.

[0008] Preferably, second sliding grooves are provided on both sides of the interior of the connecting plate, second sliding blocks are fixedly connected to both sides of the buckle, and the interior of the second sliding groove is slidably connected to the second sliding block.

[0009] Preferably, a friction plate is installed on the surface of the slot.

[0010] Preferably, a tight groove is provided at the top and bottom of the connection groove, a tight plate is fixedly connected to the top and bottom of the connection block, and the inside of the tight groove is slidably connected to the tight plate.

[0011] Technical effects and advantages of the utility model:

[0012] In the utility model, the two second walls are spliced ​​by aligning the connecting grooves with the connecting blocks, and after completion, the card slots on the top plate are aligned with the buckles and snapped in. After the snapping in is completed, the buckles can be firmly fixed in the card slots by the elastic force of the elastic spring, so that the top plate is firmly limited in position. When it is necessary to disassemble it, the push-pull plate is pushed inward to make the sliding rod push the buckles to release the engagement with the card slots, thereby achieving the rapid release of the top plate. The first wall, the second wall and the top plate that can be quickly installed and removed can significantly shorten the time for site preparation and conversion. It is particularly suitable for rental sites or occasions that require frequent relocation, and reduces the downtime caused by waiting for site preparation, thereby improving resource utilization and work efficiency, and reducing overall operating costs.

By aligning the connecting groove 4 with the connecting block 5, the two second walls 2 are spliced. After completion, the slot 10 on the top plate 3 is aligned with the buckle 8 and snapped in. After the snapping is completed, the buckle 8 can be firmly fixed in the slot 10 through the elastic force of the elastic spring 9, so that the top plate 3 is firmly limited. When it needs to be disassembled, the push-pull plate 14 is pushed inward to make the sliding rod 13 push the buckle 8 to release the snap connection with the slot 10, thereby achieving the rapid release of the top plate 3. The first wall 1, the second wall 2 and the top plate 3 that can be quickly installed and disassembled can significantly shorten the time for site preparation and conversion, which is particularly suitable for rental sites or occasions that require frequent migration, and reduces the downtime caused by waiting for site preparation, thereby improving resource utilization and work efficiency, and reducing overall operating costs.

[0022] Reference Figure 5As shown, in this embodiment: first sliding grooves 15 are opened on both sides of the sliding sleeve 12, and first sliding blocks 16 are installed on both sides of the sliding rod 13. The interior of the first sliding groove 15 is slidably connected with the first sliding block 16. Through the arrangement of the first sliding groove 15 and the first sliding block 16, the sliding rod 13 can be firmly limited when pushed and pulled to prevent the sliding rod 13 from being pulled off from the sliding sleeve 12 due to excessive pulling, thereby affecting the stability of use.

Through the setting of the tight groove 21 and the tight plate 22, the first wall 1 and the second wall 2 can be in closer contact during splicing, thereby improving the stability of the first wall 1 and the second wall 2 when they are fixed.

[0027] Working principle: by aligning the connecting groove 4 with the connecting block 5, the two second walls 2 are spliced, and after completion, the slots 10 on the top plate 3 are aligned with the buckles 8 and snapped into place. After the snapping is completed, the buckles 8 can be firmly fixed in the slots 10 by the elastic force of the elastic springs 9, so that the top plate 3 is firmly limited. When it is necessary to disassemble it, the push-pull plate 14 is pushed inward to make the sliding rod 13 push the buckle 8 to release the engagement with the slot 10, thereby achieving the rapid release of the top plate 3. The first wall 1, the second wall 2 and the top plate 3 that can be quickly installed and disassembled can significantly shorten the time for site preparation and conversion, which is especially suitable for rental sites or occasions that require frequent relocation, reduces the downtime caused by waiting for site preparation, thereby improving resource utilization and work efficiency, and reducing overall operating costs. By setting the first slide groove 15 and the first slider 16, the sliding The movable rod 13 forms a stable limit when pushing and pulling, preventing the sliding rod 13 from being pulled off the sliding sleeve 12 due to excessive pulling, affecting the stability of use. Through the setting of the elastic sheet 17, the sliding rod 13 can be quickly reset after being pushed, which is convenient for the staff to use next time. Through the setting of the second sliding groove 18 and the second sliding block 19, the buckle 8 can form a stable limit when moving inside the connecting plate 7, thereby effectively improving the clamping stability of the buckle 8 and the clamping groove 10, and improving the installation effect of the top plate 3. Through the setting of the friction plate 20, the buckle 8 can have a greater friction force after being clamped with the clamping groove 10, preventing shaking and falling off, affecting the use effect. Through the setting of the tight groove 21 and the tight plate 22, the first wall 1 and the second wall 2 can be in closer contact when splicing, thereby improving the stability of the first wall 1 and the second wall 2 when fixed.
