[0002] The valve body structure sometimes needs to be installed on a movable platform. When the platform moves, it is inevitable that there will be bumps. Even with the protection of the valve box, a large part of the impact will be transmitted to the valve body structure inside the valve box, which will increase the probability of valve body failure. Summary of the Invention

[0003] The purpose of this application is to provide a valve box base with a buffer function that can effectively reduce the probability of valve body damage.

[0004] To achieve the above objectives, this application provides a valve box base with a buffer function: including a base and a mounting platform, the mounting platform being suitable for mounting a valve box structure, a buffer being provided between the mounting platform and the base, the buffer including a support part and an elastic part, the main body of the elastic part being an airbag body, the airbag body being fixedly connected to the base, the upper end of the airbag body having a mating opening, the support part including a hollow cylinder fixedly connected to the mating opening, the lower end of the hollow cylinder being located inside the airbag body, the upper end of the hollow cylinder being fixedly connected to the mounting platform, the portion of the hollow cylinder outside the airbag body having an external convection hole, allowing air to flow through and generating an air damping effect.

[0012] Compared with the prior art, the beneficial effects of this application are as follows:

[0022] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0025] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0026] like Figure 1-6 The valve box base with buffer function shown includes a base 1 and a mounting platform 3 that are parallel to each other. Normally, the base 1 is set horizontally and has a connecting hole 101 for bolts and other connecting parts to pass through and fix the base 1 to the placement surface. The mounting platform 3 is used to install the valve box structure. A buffer 2 is set between the mounting platform 3 and the base 1. It is the core component to realize the buffer function. At least three buffers 2 are set. These buffers 2 need to form a polygon to ensure the stability of the mounting platform 3. In this embodiment, four buffers 2 are set, which are located below the four corners of the rectangular mounting platform 3, so as to keep the mounting platform 3 stable.

[0027] The buffer 2 includes a support part 210 and an elastic part 220 that cooperate with each other. The main body of the elastic part 220 is an airbag 221. The airbag 221 is made of rubber material and has a certain elasticity and support strength. Even if a valve box structure is placed on the mounting platform 3, it will not be crushed. The airbag 221 is fixedly connected to the base 1. In fact, the lower end of the airbag 221 is fixedly connected to a lower fixing plate 223. The lower fixing plate 223 is made of plastic. The airbag 221 and the lower fixing plate 223 can be fixedly connected together by secondary injection molding. The bottom surface of the lower fixing plate 223 is fixedly connected to the upper surface of the base 1. The lower fixing plate 223, which has a larger cross-sectional area, can effectively disperse the pressure of the airbag 221 contacting the base 1.

[0028] The upper end of the airbag body 221 is provided with a mating port 222. The support part 210 is an integral structure made of plastic. Specifically, the support part 210 includes a hollow cylinder 211 fixedly connected to the mating port 222. In fact, the outer side of the hollow cylinder 211 also has a connecting ring 213. The outer side of the connecting ring 213 is fixedly connected to the inner wall of the mating port 222 by a curing adhesive. The upper end of the hollow cylinder 211 has an upper fixing ring 214. The upper end face of the upper fixing ring 214 is fixedly connected to the bottom surface of the mounting platform 3. The upper fixing ring 214 with a larger cross-section can effectively improve and reduce the contact pressure between the hollow cylinder 211 and the mounting platform 3.

[0029] The lower end of the hollow cylinder 211 is located inside the airbag body 221, and the lower end of the hollow cylinder 211 also has an embedded disc 212. An inner convection hole 215 that runs through the upper and lower ends is opened in the center of the embedded disc 212. The upper end of the hollow cylinder 211 is fixedly connected to the mounting platform 3. An outer convection hole 216 is opened in the part of the hollow cylinder 211 outside the airbag body 221, that is, in the part between the upper connecting ring 213 and the upper fixing ring 214. The airbag body 221 is connected to the outside through the inner convection hole 215 and the outer convection hole 216.

[0030] Working principle: The base 1 is fixed on the moving platform, and the valve box structure is fixed on the mounting platform 3. When the moving platform suddenly rises, the impact from the moving platform is not directly transmitted to the valve box structure on the mounting platform 3. Instead, it first forces the airbag 221 to compress. The air inside the airbag 221 enters the hollow cylinder 211 through the extremely narrow inner convection hole 215, and then enters the atmosphere through the outer convection hole 216. Subsequently, the elasticity of the airbag 221 gradually expands, and the airbag 221 expands through the outer convection hole 216 and the inner convection hole. The hole 215 draws in outside air, transmitting the lifting effect to the valve box structure on the mounting platform 3 in a gentler manner. When the moving platform suddenly descends, the elastic airbag 221 draws in air and then releases it, in the opposite manner to the above process. As long as the airbag 221 deforms, mechanical kinetic energy is converted into heat energy of the air, thereby reducing the impact of the moving platform's bumps on the valve box structure on the mounting platform 3. Therefore, the valve box base has a good buffer function and can effectively reduce the probability of damage to the internal structure of the valve box.

[0031] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
