Technical Field

[0001] The utility model relates to the technical field of installation devices, and more specifically, to an installation device for protecting a vacuum gauge. Background Art

[0002] A vacuum gauge, also known as a vacuum meter, is an instrument for measuring vacuum degree or air pressure. Generally, it measures air pressure by utilizing the change of a certain physical effect of gas under different air pressures. It is widely used in scientific research and industrial production. According to the different physical mechanisms utilized in the measurement principle of the vacuum gauge, the main vacuum gauges can be divided into three categories, namely vacuum gauges that utilize mechanical properties, gas dynamics effects, and charged particle effects.

[0003] Currently, when using a vacuum gauge, generally the vacuum gauge is directly connected and installed on a cavity; the vacuum gauge is installed on a spiral vacuum tube connector. However, in the actual use of such a vacuum device, the vacuum gauge is easily contaminated and damaged, and the vacuum gauge is relatively expensive. Therefore, it is necessary to design a protective installation structure for the vacuum gauge to reduce the damage to the vacuum gauge caused by pollutants and plating materials.

Detailed implementation manner

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] As Figures 1 to 5 shown, the present invention provides an installation device for protecting a vacuum gauge, including a vacuum gauge 1. A filtering component is arranged outside the vacuum gauge 1. The filtering component includes a first connecting pipe 2 communicated with the outside of the vacuum gauge 1. The end of the first connecting pipe 2 is fixedly connected with a connector 5. There are four connectors 5. The outside of the first connector 5 abuts against a first central support 6. A filter net is fixedly connected inside the first central support 6. There are two first central supports 6. The outside of the first central support 6 abuts against the second connector 5. The outside of the second connector 5 is fixedly connected with a second connecting pipe 3. The end of the second connecting pipe 3 is fixedly connected with a third connector 5. The outside of the third connector 5 abuts against the second first central support 6. The outside of the second first central support 6 abuts against the fourth connector 5. The outside of the fourth connector 5 is fixedly connected with a third connecting pipe 4.

[0022] Through the filter nets inside the two first central supports 6 provided, the air entering the inside of the vacuum gauge 1 can be filtered, thereby reducing the possibility of the inside of the vacuum gauge 1 being contaminated and reducing the possibility of the vacuum gauge 1 being damaged.

[0023] Among them, a clamping component is arranged outside the connector 5. The clamping component includes a lower fixing block 7 slidably sleeved outside the two connectors 5. The top of the lower fixing block 7 is fixedly connected with a lower rotating seat 8. The inside of the lower rotating seat 8 is rotatably connected with an upper rotating seat 9. The top of the upper rotating seat 9 is fixedly connected with an upper fixing block 10.

[0024] By sleeving the lower fixing block 7 outside the two connectors 5, then rotating the upper fixing block 10 so that the upper fixing block 10 is also sleeved outside the two connectors 5, the position of the connectors 5 is fixed, so that the two connectors 5 can clamp the first central support 6, so that the filter screen can be fixed between the first connecting pipe 2, the second connecting pipe 3 and the third connecting pipe 4, and the gas is filtered multiple times.

[0025] Among them, a fixing component is arranged outside the lower fixing block 7. The fixing component includes a screw rod 11 rotatably connected inside the lower fixing block 7. A threaded fixing block 12 is threadedly connected to the outside of the screw rod 11. The bottom of the threaded fixing block 12 abuts against the top of the upper fixing block 10.

[0026] By rotating the screw rod 11, the threaded fixing block 12 is driven to move to the top of the upper fixing block 10. Then, by rotating the threaded fixing block 12, the distance between the upper fixing block 10 and the lower fixing block 7 can be compressed, so that the upper fixing block 10 and the lower fixing block 7 can clamp the two connectors 5 more tightly, thereby improving the sealing performance.

[0027] Among them, a connecting component is arranged outside the third connecting pipe 4. The connecting component includes a manual valve 13 fixedly communicated with the outside of the third connecting pipe 4. A fourth connecting pipe 14 is communicated with the bottom of the manual valve 13. A limiting disc 15 is fixedly connected to the bottom of the fourth connecting pipe 14.

[0028] Among them, the connecting component further includes a second central support 16 fixedly connected to the bottom of the limiting disc 15. A filter screen is fixedly connected inside the second central support 16.

[0029] Through the limiting disc 15, it can be fixed to the rest of the machine, and the gas entering is filtered for the first time by the filter screen inside the second central support 16. When the vacuum gauge 1 needs to be replaced, the manual valve 13 can be rotated to block the flow of gas, so as to facilitate the subsequent replacement of the vacuum gauge 1.

[0030] Among them, the first connecting pipe 2 and the second connecting pipe 3 are made of metal, and the third connecting pipe 4 and the connectors 5 are made of metal.

[0031] By making the first connecting pipe 2, the second connecting pipe 3, the third connecting pipe 4 and the connectors 5 made of metal, the service life is improved.

[0032] Working principle and usage process of the present utility model: Through the limit disc 15, it can be fixed to other machines, and the gas entering is first filtered by the filter screen inside the second central support 16. Subsequently, through the filter screens inside the two first central supports 6 provided, the air entering the vacuum gauge 1 can be filtered again, thereby reducing the possibility of the inside of the vacuum gauge 1 being contaminated and reducing the possibility of damage to the vacuum gauge 1. When the vacuum gauge 1 needs to be replaced, the manual valve 13 can be rotated to block the gas flow, thereby facilitating the subsequent replacement of the vacuum gauge 1.
