Description
Technical Field
[0001] The utility model relates to the technical field of vacuum cavity devices, in particular to a vacuum cavity device. Background Art
[0002] The meaning of vacuum refers to the state of gas below one atmospheric pressure in a given space, which is a physical phenomenon. In the "void", sound cannot be transmitted because there is no medium, but the transmission of electromagnetic waves is not affected by vacuum. In fact, in vacuum technology, vacuum refers to the atmosphere. When part of the material inside a specific space is discharged, making its pressure less than one standard atmospheric pressure, we generally call this space a vacuum or vacuum state. In the natural environment, only outer space can be regarded as the space closest to vacuum. Many modern high-precision products must use different degrees of vacuum to be manufactured at certain stages of the manufacturing process, such as semiconductors, hard disks, and lenses. The method of creating vacuum in laboratories and factories is to use a pump to extract air in a closed space to achieve a certain degree of vacuum, so a vacuum cavity device appears. However, the existing partial vacuum cavity device cannot form a relatively stable fixed relationship with the ground, and it is also impossible to determine whether the interior of the vacuum cavity device is in a vacuum state and how much vacuum state it is in. Therefore, a person skilled in the art provides a vacuum cavity device to solve the problems raised in the above background technology. Summary of the invention
[0003] The purpose of the utility model is to provide a vacuum chamber device to solve the problems raised in the above background technology.
[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] Preferably, a vacuum device body cover plate is provided on the upper side of the vacuum device body, an upper buckle is provided at the middle front end of the lower side of the vacuum device body cover plate, and an upper buckle groove is provided on the outer side of the upper buckle; an upper sealing ring is provided on the lower side of the vacuum device body cover plate; a resist plate is provided in the middle inner part of the front surface of the vacuum device body, a lower sealing ring is provided on the rear side of the resist plate, and electric push rods are provided at the upper and lower ends of the middle of the front side of the resist plate.
[0007] Compared with the prior art, the utility model has the following beneficial effects: when in use, the main body of the vacuum device is first placed horizontally on the ground, and then the positioning pin is rotated until the lower half of the positioning pin is completely inserted into the ground, at which time the device is fixed to the ground, so that the device can be more stable in the subsequent working process, and the vacuum environment inside the main body of the vacuum device can be prevented from being damaged due to the tipping of the device. Then the vacuum pump is started, and the vacuum pump will suck the air inside the main body of the vacuum device from the vacuum pump air inlet pipe, and then discharge it from the vacuum pump air outlet pipe, and then the vacuum pressure gauge can be observed to judge whether the inside of the main body of the vacuum device is in a vacuum state. Avoid the situation where the interior of the vacuum device body cannot reach a vacuum state due to air leakage from the vacuum device body. In general, the smaller the value displayed on the vacuum pressure gauge, the better the vacuum state. After the vacuum state inside the vacuum device body reaches the preset value, turn off the vacuum pump. At this time, the interior of the vacuum device body can be completely in a vacuum state. When it is necessary to open the cover of the vacuum device body, the electric push rod can be started. The electric push rod will drive the push plate to move forward until the push plate is completely separated from the vacuum device body. Then the air outside the vacuum device body will flow into the interior of the vacuum device body, thereby making the internal pressure of the vacuum device body and The external pressure is the same, so as to avoid the situation that the internal pressure of the vacuum device body is lower than the external pressure and the vacuum device body cover cannot be opened.

The device is provided with a positioning pin, which can make the vacuum device body and the ground more stable. The device is solid, thereby improving the stability of the device; the device is provided with a vacuum pressure gauge, and the vacuum pressure gauge can be used to determine whether the interior of the vacuum device body is in a vacuum state, and the vacuum pressure gauge can also be used to determine whether the device is leaking; the device is provided with an upper sealing ring and a lower sealing ring, so that the device has better sealing performance, and the cover of the vacuum device body can be opened by pressing the center button, thereby improving the convenience of the device; the device is provided with an electric push rod, and the push rod can be used to separate the abutment plate from the vacuum device body, avoiding the situation where the cover of the vacuum device body cannot be opened due to the excessively low pressure inside the vacuum device body.
