Description

Technical Field

[0001] The utility model relates to the technical field of vacuum gauges, in particular to a negative pressure vacuum gauge storage mechanism. Background Art

[0002] The vacuum pressure gauge is based on atmospheric pressure and is used to measure instruments with pressures less than atmospheric pressure. The vacuum pressure gauge is suitable for measuring the vacuum pressure of liquids and gases that are non-explosive, non-crystallized, non-solidified, and non-corrosive to copper and copper alloys. It is widely used in gas transportation, pipeline liquids and closed containers to measure the pressure of various liquids, gases, steam and other media that are non-corrosive, non-explosive, non-crystallized, and non-solidified, such as various industrial automatic control environments, involving many industries such as oil pipelines, water conservancy and hydropower, railway transportation, intelligent buildings, production automatic control, aerospace, military industry, petrochemicals, oil wells, electricity, ships, machine tools, pipeline air supply, vacuum equipment and medical treatment.

[0003] For example, a Chinese patent (publication number: CN217023389U) discloses a vacuum storage box for gas measuring instruments, comprising a box body and a box door, wherein a plurality of storage compartment groups are placed in the inner cavity of the box body, each storage compartment group comprising a plurality of storage compartments stacked in the height direction, a plurality of conveying assemblies comprising horizontal conveying devices and lifting conveying devices are installed on the bottom surface of the inner cavity, a horizontal push assembly is installed on the side wall of the inner cavity, the horizontal push assembly comprises a plurality of horizontal push devices arranged in the height direction, the utility model can safely and stably store the gas measuring instrument to a high place or take it out from the storage compartment at a high place through the conveying assembly and the horizontal push assembly, without the need for users to climb a ladder for access, thereby preventing the gas measuring instrument from falling from a high place and being damaged during the storage and access process.

[0004] The above-mentioned gas measuring instrument vacuum storage box still has certain shortcomings. Under the premise that the box body is customized to have a high height to save floor space and store more gas measuring instruments, the gas measuring instruments can be safely and stably stored in a high place or taken out from a high storage compartment through a conveying assembly and a horizontal push assembly, without the need for users to climb ladders for access, thus preventing the gas measuring instruments from falling from a height and being damaged during the storage and access process. However, only placing the vacuum meter in the storage compartment cannot fix the vacuum meter inside the storage compartment, resulting in the vacuum meter shaking in the storage compartment during the movement, and even causing the vacuum meter to collide with the storage compartment and be damaged. Therefore, the present application proposes a negative pressure vacuum meter storage mechanism to solve the above-mentioned problem. Utility Model Content

When the threaded rod 502 rotates, it drives the push block 503 to slide on the outer surface of the vertical rod, thereby increasing the stability of the push block 503 when it moves. When the push block 503 moves, it pushes the two moving blocks 504 to move back to each other at the same time. The moving block 504 drives the vertical plate 507 to slide on the outer surface of the limit rod 508 and squeezes the first spring 509.
