[0032] Workflow description

[0033] Install the soft pad 5:

[0034] Place the soft pad 5 in the installation groove 401 of the seat plate 4, pull the connecting plate 605 of the locking piece 6, make the sliding rod 603 slide in the installation box 601, compress the spring 604, put the rope sleeve 606 of the soft pad 5 into the arc-shaped gap 6051, release the connecting plate 605, the spring 604 rebounds, the sliding rod 603 drives the connecting plate 605 to reset, so that the soft pad 5 can be fixed.

[0035] Dismount the soft pad 5:

[0036] Pull the connecting plate 605 of the locking piece 6 outward again, take the rope sleeve 606 out of the arc-shaped gap 6051, release the fixing of the soft pad 5 rope sleeve 606, take out the soft pad 5 from the installation groove 401, and clean or replace it.

[0037] Use the seat:

[0038] The user sits on the soft pad 5, regularly dismounts the soft pad 5 for cleaning, and maintains the hygiene of the seat.

[0039] The aluminum alloy chair with detachable soft pad 5 is designed for easy cleaning, reduces the accumulation of dirt and bacteria, and protects the health of the user. The soft pad 5 can be replaced separately, avoiding the replacement of the whole seat, reducing the use cost, the design of the locking piece 6 ensures the stable installation of the soft pad 5, reduces the wear caused by loosening, and prolongs the service life of the seat.

[0040] As shown in Figure 1 some embodiments, the cross section of the installation groove 401 is trapezoidal, and the bottom of the installation groove 401 is uniformly distributed with spherical protrusions 402. More specifically, the cross section of the installation groove 401 is trapezoidal, that is, the slot width is less than the slot bottom width, forming a structure of narrow top and wide bottom. This design allows the soft pad 5 to naturally fit into the groove during installation, and the groove wall forms a certain limiting action on the soft pad 5, preventing the soft pad 5 from shifting or slipping during use. The bottom of the installation groove 401 is uniformly distributed with multiple spherical protrusions 402, which can prevent the soft pad 5 from shifting.

[0041] As shown in Figure 4As shown, in some embodiments, the soft pad 5 is composed of a cloth cover and a latex pad, and the latex pad is embedded in the interior of the cloth cover. More specifically, the latex pad has good elasticity and cushioning performance, can automatically adjust the shape according to the weight and sitting posture of the user, effectively reduces the burden of the body pressure points, and provides comfortable support for the hips, legs and other parts. The cloth cover plays a certain protective role for the latex pad, so that it is protected from direct erosion of the external environment. In daily use, some dust, stains and other impurities may come into contact with the surface of the soft pad 5, and the cloth cover can serve as the first line of defense to reduce damage to the latex pad. At the same time, the existence of the cloth cover can also prevent the latex pad from being oxidized and aged due to long-term exposure to air, thereby prolonging the service life of the latex pad.

[0042] As shown in the Figure 2 embodiments, the top of the support rod 1 is sleeved with a rubber sleeve 101. More specifically, the rubber sleeve 101 is relatively soft in texture, which can provide a more comfortable touch for the user's hands compared to the top of the support rod 1 made of metal or hard plastic material. When the hands are in contact with the support rod 1 for a long time, the rubber sleeve 101 can reduce the pressure and friction on the skin of the hands, reducing fatigue. To some extent, the rubber sleeve 101 can also act as a buffer. When the user's hands accidentally hit or press the top of the support rod 1, the rubber sleeve 101 can deform to absorb part of the impact force, reducing the pain and discomfort of the hands.

[0043] As shown in the Figure 2 embodiments, the backrest 7 is arc-shaped, and the front end of the seat plate 4 is configured with a rounded corner. More specifically, the backrest 7 is designed in an arc shape, so that the user's back can be effectively supported by the backrest 7, reducing fatigue and preventing back pain and discomfort caused by long-term maintenance of an improper sitting posture. The rounded corner design avoids the possibility of sharp edges causing harm to the human body. When the user sits on the edge of the chair, the rounded corner design allows the legs to be more comfortable in contact with the seat plate 4.

[0044] As shown in the Figure 2 embodiments, a pedal 9 is also included, which is located in front of the surface of the second connecting rod 3 and is fixedly arranged with an extension rod. The pedal 9 is fixedly arranged at the end of the extension rod. More specifically, the pedal 9 is part of the chair and is connected to the structure of the chair, which can provide additional stable support. When the user sits on the chair, the feet are placed on the pedal 9, and the body posture can be adjusted to maintain balance. Especially when performing some actions that require the body to lean forward or backward, the pedal 9 can act as a support to prevent the chair from tipping over.

[0045] The above description of disclosed embodiments enables one of ordinary skill in the art to make or use the application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein can be applied to other embodiments without departing from the spirit or scope of the application. Thus, the present application is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
