Description

Technical Field

[0001] The utility model belongs to the technical field of high-precision balance weighing and shockproofing, in particular to an airbag type shockproof platform. Background Art

[0002] In recent years, in the pharmaceutical industry, in order to make accurate drug composition ratios for drugs, high-precision balances or industrial scales are used more and more frequently. However, when using high-precision balances or industrial scales, it is necessary to ensure the weighing accuracy requirements at the placement position. Generally, they are placed on a relatively stable horizontal platform. The platform is heavy and the leveling process is more difficult. Therefore, the platform cannot be moved after leveling to avoid secondary leveling. At the same time, when weighing with a high-precision balance or industrial scale, the vibration amplitude is required to be less than a certain range to ensure the accuracy of the weighing results. Therefore, the balance or industrial scale must be placed in a fixed position and a fixed small-amplitude room, which will cause inconvenience in workflow operations. Utility Model Content

[0003] The utility model provides an airbag anti-vibration platform, which solves the problems in the prior art that the platform can only be placed in a fixed position, resulting in complicated work processes, difficulty in secondary leveling of a relatively heavy platform, and a small requirement for the platform vibration amplitude range during weighing.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] Airbag anti-vibration platform, including:

[0006] a support platform having a horizontal support surface disposed thereon;

[0007] A plurality of shock-absorbing airbags, a plurality of which are provided with inflation ports, and a plurality of which are in contact with the support platform to keep the support platform in a horizontal state;

[0008] The bottom plate box is provided with a first cavity, a plurality of the shock absorbing airbags are located in the first cavity and the plurality of the shock absorbing airbags are connected to the inner bottom of the bottom plate box.

[0009] In some embodiments, it further includes a first bracket sleeved on the outside of the base box, the first bracket is connected to the support platform, and a first distance is set between the first bracket and the base box.

[0011] In some embodiments, the number of the shock-absorbing airbags is three, and the three shock-absorbing airbags are non-collinearly arranged.

[0012] In some embodiments, an air inlet is provided on the first bracket, and the air inlet is connected to the inflation port of the shock-absorbing airbag, wherein the air inlet is a one-way valve structure.

[0013] In some embodiments, a cross-shaped four-way joint is provided between the air inlet and the inflation port, one of the four air vents of the cross-shaped four-way joint is connected to the air inlet, and the other three air vents are respectively connected to the corresponding three inflation ports of the shock-absorbing airbags.

[0014] In some embodiments, a pressure regulating throttle valve is provided between the three vents of the cross four-way joint and the corresponding inflation ports of the shock-absorbing airbag, respectively. The pressure regulating throttle valve is disposed on the first bracket, and a switch of the pressure regulating throttle valve is disposed on the outside of the first bracket.

[0015] In some embodiments, a clearance notch is provided on the bottom plate box, and the position of the clearance notch corresponds to the position of the pressure regulating throttle valve.

[0017] In some embodiments, the support platform is a marble platform.

[0018] Compared with the prior art, the beneficial effects brought by the utility model are:

By setting up a one-way valve-type air inlet, the air pressure of the shock-absorbing airbag can be kept stable, and there will be no large pressure changes in a short period of time, ensuring the horizontality of the marble platform. At the same time, the pressure regulating throttle valve is used to adjust the air pressure in the shock-absorbing airbag and the height of the marble to keep the marble platform in a horizontal state.

[0027] like Figure 1-3 As shown, the airbag type shockproof platform provided by the utility model includes a supporting platform 100, a plurality of shock-absorbing airbags 300 and a bottom box 400. The supporting platform 100 is a marble platform with a horizontal surface. The overall flatness and parallelism control accuracy of the marble platform are less affected by the ambient temperature and the deformation is extremely small, ensuring that the placement surface has the flatness required for placing a balance or an industrial scale; the supporting platform 100 abuts against one side of the shock-absorbing airbag 300 and is supported by the shock-absorbing airbag 300, and the other side of the shock-absorbing airbag 300 is fixedly arranged on the inner bottom edge of the bottom box 400, and a first cavity 402 is provided on the bottom box 400, and the shock-absorbing airbag 300 is located in the first cavity 402, wherein an inflation port 301 is provided on the shock-absorbing airbag 300, which is connected to an external air pump to put the shock-absorbing airbag 300 in an inflated state, thereby ensuring effective support for the supporting platform 100. In this embodiment, the support platform made of marble is supported by a shock-absorbing airbag 300, which can absorb vibration waves, avoid tilting and reduce vibration when performing a high-precision balance weighing experiment on the support platform 100, thereby ensuring the accuracy of the weighing results.

[0028] In one embodiment, the airbag type shockproof platform also includes a first bracket 200 arranged outside the bottom box 400. The first bracket 200 provides an installation position, which is mainly used for the installation of parts. The first bracket 200 is fixedly connected to the support platform 100. At the same time, a first spacing is provided between the first bracket 200 and the side wall of the bottom box 400.

Specifically, a plurality of first fixing holes 204 are provided on the first bracket 200, and a first threaded hole is provided at a corresponding position at the bottom of the support platform 100. The first bracket 200 and the support platform 100 are locked and fixed by a second screw. In this embodiment, in order to protect the marble support platform, the first bracket and the bottom box are both made of stainless steel. Since the stainless steel material has an anti-corrosion function, the possibility of environmental and material pollution can be eliminated.

[0029] In one embodiment, in order to facilitate the connection between the shock-absorbing airbag 300 and the supporting platform 100, a first mounting plate 302 is set on the shock-absorbing airbag 300, a first mounting hole 3021 is set on the first mounting plate 302, and a second mounting hole 101 is correspondingly set on the supporting platform 100. The first mounting plate 302 is fixedly connected to the supporting platform 100 through the first mounting hole 3021 and the second mounting hole 101 to prevent the supporting platform 100 from being separated from the shock-absorbing airbag 300.

[0030] In one embodiment, in order to provide reasonable support for the support platform 100 and reduce the number of installed parts, the number of shock-absorbing airbags 300 is preferably 3.

[0032] Furthermore, in order to reduce the number of air inlets 202 and avoid designing a more complex air pipe connection structure, a cross four-way joint 203 is set between the air inlet 202 and the inflation port 301, and the four air vents of the cross four-way joint 203 are respectively connected to the air inlet 202 and the inflation ports 301 of the three shock-absorbing airbags 300.

[0033] Furthermore, in order to facilitate the adjustment of the air pressure in the shock-absorbing airbag 300 and keep the supporting platform 100 in a horizontal state, a pressure regulating throttle valve 201 is provided between the cross four-way joint 203 and the inflation port 301. Specifically, the pressure regulating throttle valve 201 is provided on the first bracket 200 and is set according to the number of shock-absorbing airbags 300.

Optionally, the positions of the 3 pressure regulating throttle valves 201 can be dispersedly provided on different sides of the first bracket 200.

[0034] In one embodiment, due to the need to adjust the air pressure of the shock-absorbing airbag 300, the support platform 100 will move closer to the side of the base box, and the air inlet 202 and the pressure regulating throttle valve 201 on the first bracket 200 will move. In order to avoid the air inlet 202 and the pressure regulating throttle valve 201 from interfering with the base box 400, a clearance slot 401 is provided on the base box 400 to make way for the movement of the air inlet 202 and the pressure regulating throttle valve 201.
