[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a wall-mounted two-stage decompression chamber, which has the following features:

[0016] Beneficial effects:

[0017] 1. The wall-mounting mechanism, through the tight connection between the fixed plate and the bracket, ensures a stable connection between the cabinet and the external wall, maintaining the stability of the equipment during use. The bracket, through its rotatable connection with the connecting frame, allows for flexible adjustment of the equipment's position during installation, facilitating precise installation according to actual needs. The screw connection between the limit bolt and the bracket and connecting frame provides stronger fixing force, preventing the equipment from loosening or shifting during use. The design of the mounting holes offers diverse installation options, allowing users to adjust the installation method according to specific circumstances, thereby improving the overall convenience and adaptability of installation.

[0018] 2. The fixing mechanism, through the combined design of the fixing sleeve and the plug, provides a more stable and efficient fixing method. After the plug is inserted into the mounting hole and combined with the fixing sleeve, it can ensure that the equipment can be firmly fixed to the wall after being hung, preventing the risk of accidental fall. The design of the inclined groove and the slider makes the force distribution during the fixing process more uniform, which can effectively reduce the friction during fixing and reduce the resistance during operation, making the installation process smoother. The combination of the telescopic spring and the clamping plate enhances the clamping effect during the snap-fit ​​process through appropriate elasticity, making the connection between the slot and the clamping plate more firm and durable. The configuration of the rubber pad further improves the friction between the clamping plate and the slot, ensuring that the equipment can remain firmly fixed during long-term use.

[0019] 3. The linkage mechanism design provides an efficient operating experience for installation and disassembly. Through the meshing transmission of the gear ring and gear, the screw and transmission plate are threaded together, achieving smooth and precise sliding control. The combination of the slide cylinder and the movable rod, along with the pushing action of the abutment plate and the slider, makes the entire fixing process smoother, avoiding the jamming or imbalance problems that may occur in traditional methods. At the same time, the cooperation between the abutment plate and the slider ensures that the clamping plate can evenly and forcefully fix the plug, further improving the stability of the equipment installation. During disassembly, the linkage mechanism can also easily loosen the clamping plate and the slot through rotation, simplifying the disassembly process, reducing the complexity of manual operation, and improving the overall efficiency and convenience of operation.

The gear ring 21 is located on the outer wall of the rotating sleeve 20. Multiple sets of screws 22 are rotatably installed on the outside of the fixed sleeve 7 and are threadedly connected to multiple sets of transmission plates 19. The gear 23 is installed at the top of multiple sets of screws 22 and meshes with the gear ring 21.

[0031] A positioning block 24 is installed at the top of the plug 8, and a positioning hole 25 is opened at the top of the fixing sleeve 7.

[0032] The cooperation between the positioning block 24 and the positioning hole 25 can accurately position the plug 8 and the fixing sleeve 7, avoid offset or misalignment, and ensure the stability and accuracy of the equipment fixing process.

[0033] Both the positioning block 24 and the positioning hole 25 are set as polygons and are compatible with each other.

[0034] The polygonal design makes the connection between the positioning block 24 and the positioning hole 25 more secure, effectively preventing rotation or sliding, enhancing the stability of the connection, and preventing the components from shifting during installation.

[0035] Rubber pads 26 are installed on the inner side of multiple sets of clamping plates 13.

[0036] The rubber pad 26 provides better friction, which can effectively prevent the clamping plate 13 from sliding between other parts, ensuring that the equipment is firmly fixed during installation, enhancing the clamping effect and preventing loosening.

[0037] Connecting springs 27 are provided between the inner sides of multiple sets of sliding cylinders 16 and the movable rods 17.

[0038] The connecting spring 27 keeps the slide cylinder 16 and the movable rod 17 in an elastic connection, reduces frictional resistance, ensures smoother and more stable sliding of the equipment, and improves stability during operation.

[0039] The outer wall of the fixed sleeve 7 is provided with a guide plate 28, and the guide plate 28 is provided with multiple sets that are slidably connected to multiple sets of transmission plates 19.

[0040] The sliding connection between the guide plate 28 and the transmission plate 19 helps the transmission plate 19 slide smoothly, reduces friction, avoids jamming problems, and thus improves the smoothness and efficiency of the installation and disassembly process.

[0041] The outer sides of multiple sets of abutment plates 18 are all rounded.

[0042] The rounded corner design effectively reduces the sharp angles when the contact plate 18 comes into contact with other components, avoiding possible wear or damage, improving the durability of the components, and ensuring safety during operation.

[0043] In this embodiment, when it is necessary to fix the housing 1, the fixing plate 2 is aligned with the mounting hole 6 on the connecting frame 4, the plug 8 is inserted into the mounting hole 6, and then the fixing sleeve 7 is inserted into the plug 8. The rotating sleeve 20 drives the multiple sets of screws 22 to rotate through the meshing of the gear ring 21 and multiple sets of gears 23, and engages with the transmission plate 19 in a threaded engagement. This causes the multiple sets of transmission plates 19 to drive the slide cylinder 16 to slide along the slide groove 15 and drive the abutment plate 18 through the movable rod 17 to push the slider 10 to slide along the inclined groove 9. The slider 10 drives the multiple sets of clamping plates 13 to clamp the plug 8 on the outside of the slot 14. The friction between the clamping plates 13 and the slot 14 is increased by the multiple sets of rubber pads 26.

[0044] More specifically, when disassembly is required, the engagement of the gear ring 21 with the gear 23 drives the screw 22 to engage with the transmission plate 19, causing the slide cylinder 16 to slide along the slide groove 15, thereby releasing the contact between the abutment plate 18 and the slider 10, and thus releasing the contact between the multiple sets of clamping plates 13 and the slot 14.

[0045] In summary, when the overall equipment is in use or operation: when it is necessary to fix the housing 1, align the fixing plate 2 with the mounting hole 6 on the connecting frame 4, insert the plug 8 into the mounting hole 6, and then insert the fixing sleeve 7 into the plug 8. Rotate the rotating sleeve 20 to drive multiple sets of screws 22 to rotate through the meshing of the gear ring 21 and multiple sets of gears 23, and engage with the transmission plate 19. This causes the multiple sets of transmission plates 19 to drive the slide cylinder 16 to slide along the slide groove 15 and drive the abutment plate 18 through the movable rod 17 to push the slider 10 to slide along the inclined groove 9. The slider 10 drives multiple sets of clamping plates 13 to clamp the plug 8 on the outside of the slot 14. Multiple sets of rubber pads 26 increase the friction between the clamping plates 13 and the slot 14.

[0046] When disassembly is required, the engagement of the gear ring 21 and the gear 23 drives the screw 22 to engage with the transmission plate 19, which in turn drives the slide cylinder 16 to slide along the slide groove 15, thereby releasing the contact between the abutment plate 18 and the slider 10, and thus releasing the contact between the multiple sets of clamping plates 13 and the slot 14.
