Furthermore, some aspects of this utility model can be used alone or in any suitable combination with other aspects disclosed in this utility model.

[0025] Example 1

[0026] like Figure 1-2 As shown, this is the first embodiment of the present invention, which provides a vacuum environment test chamber, including,

[0027] The test chamber unit 100 includes a test chamber body 101, and a cover plate 102 is movably connected to the top of the test chamber body 101 via a hinge.

[0028] The storage rack unit 200 includes four vertical rods 201 as shown, a horizontal rod 202 fixedly connected to the top and bottom of the vertical rods 201, and a base plate 203 fixedly connected to the lower horizontal rod 202. The test chamber unit 100 is located within the frame formed by the vertical rods 201 and the horizontal rods 202.

[0029] The drive unit 300 includes a housing 301 fixedly connected to the bottom of the base plate 203, a motor 302 fixedly connected to the inner cavity of the housing 301, a reducer 303 connected to the output end of the motor 302, a worm gear 304 connected to the output end of the reducer 303, a worm wheel 305 movably connected to the inner cavity of the housing 301 via a bearing, a threaded rod 306 fixedly connected to the top of the worm wheel 305, and a threaded sleeve 307 threadedly connected to the surface of the threaded rod 306. The end of the threaded rod 306 away from the worm wheel 305 passes through the housing 301 and is movably connected to its surface via a bearing. The top of the threaded sleeve 307 is fixedly connected to the test chamber body 101.

[0030] like Figure 1-2 As shown, the test chamber body 101, as the core container for vacuum environment testing, is used to place the sample to be tested and provide a sealed space. The cover plate 102 is movably connected to the test chamber body 101 through a hinge, which facilitates opening and closing the test chamber and makes it easy to put in and take out the sample. At the same time, a sealing ring can be set at the connection between the two to ensure the airtightness of the test chamber body 101.

[0031] The vertical rod 201 and the horizontal rod 202 form the support frame of the test chamber body 101, providing a stable support structure to ensure the stability of the test chamber body 101 during operation. They are also used to fix the drive unit 300. The bottom plate 203 serves as the bottom support of the storage rack unit 200, fixing the vacuum pump 106 and the drive unit 300, enhancing the stability of the overall structure, facilitating the installation and fixing of the equipment, and enabling the test chamber body 101 and the vacuum pump 106 to be integrated for convenient use and easy transportation.

[0032] The outer casing 301 protects the internal components such as the motor 302 and the reducer 303. The motor 302 and the reducer 303 provide power. The reducer 303 reduces the speed and increases the torque. Through the transmission of the worm gear 304 and the worm wheel 305, the threaded rod 306 is driven to rotate stably. This drives the test chamber body 101 to rise and fall through the threaded sleeve 307. This allows the test chamber body 101 to be raised out of the storage rack unit 200 during use and lowered back into the storage rack unit 200. The transmission of the worm gear 304 and the worm wheel 305 has a self-locking property, which can ensure the stability of the test chamber body 101 during the lifting and lowering process.

[0033] Example 2

[0034] Reference Figure 1 and Figure 4 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0035] In this embodiment, the test chamber unit 100 also includes a pressure gauge 103 disposed on the top of the cover plate 102, an air release valve 104 and an air inlet valve 105 connected to the left side of the test chamber body 101, and a vacuum pump 106 disposed on the top of the base plate 203. A pipe 107 is connected between the air inlet end of the vacuum pump 106 and the air inlet valve 105.

[0036] A fixing rod 308 is fixedly connected to the surface of the threaded sleeve 307. One end of the fixing rod 308 is fixedly connected to a limiting sleeve 309, which is slidably sleeved on the surface of the vertical rod 201.

[0037] like Figure 1 and Figure 4 As shown, the pressure gauge 103 monitors the air pressure inside the test chamber 101 in real time, providing air pressure data to facilitate user control of the vacuum level and ensure the accuracy of test conditions. The vent valve 104 and the inlet valve 105 control the inflow and outflow of gas inside the test chamber 101. The vent valve 104 is used to quickly restore normal pressure after the test, making it easy to remove the sample. The inlet end of the vacuum pump 106 and the inlet valve 105 of the test chamber 101 are connected by a pipe 107 to ensure that gas can be smoothly extracted from the test chamber 101 to form a vacuum environment, provide the necessary vacuum level, meet the test requirements, and ensure the accuracy of the test results.

[0038] Example 3

[0039] Reference Figure 1-3 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0040] In this embodiment, a storage groove 204 is provided on the surface of the upper crossbar 202 for storing the vent valve 104 and the intake valve 105.

[0041] A movable wheel 205 is fixedly connected to the bottom of the lower crossbar 202, and a brake pad is provided on the surface of the movable wheel 205.

[0042] The mounting bases for the vacuum pump 106, motor 302, and reducer 303 are all threadedly fixed to the base plate 203 and the outer casing 301 respectively by bolts.

[0043] The outer casing 301 has a heat dissipation vent on the left side, and a dustproof mesh is fixedly installed on the surface of the heat dissipation vent.

[0044] like Figure 1-3As shown, when the test chamber body 101 is lowered and the storage slot 204 is lowered, the vent valve 104 and the inlet valve 105 are limited. That is, when the vent valve 104 and the inlet valve 105 reach the inner cavity of the storage slot 204, the test chamber body 101 reaches the predetermined storage position. The moving wheels 205 facilitate the overall movement of the test chamber body 101, improve the flexibility of the equipment, and facilitate the transfer and use between different sites. The brake pads can ensure the stability of the equipment after movement.

[0045] The housing 301 provides heat dissipation vents to ensure the safe operation of the drive unit 300 and extend the service life of the equipment. The heat dissipation vents and dust filter prevent overheating and dust from entering.

[0046] When in use, if it is necessary to raise the test chamber body 101, power is provided by the motor 302 and the reducer 303. The reducer 303 reduces the speed and increases the torque. Through the transmission of the worm 304 and the worm wheel 305, the threaded rod 306 is driven to rotate stably. Then, the threaded sleeve 307 will drive the test chamber body 101 to move upward. The test chamber body 101 will move upward from the storage rack unit 200. After the test chamber body 101 is raised, the air inlet end of the vacuum pump 106 and the air inlet valve 105 of the test chamber body 101 are connected through the pipe 107, so that the gas can be smoothly extracted from the test chamber body 101 to form a vacuum environment. Conversely, when the use is over or when it needs to be transferred, the motor 302 is controlled to rotate in the opposite direction, and the test chamber body 101 will descend and be stored in the storage rack unit 200. The transmission of the worm 304 and the worm wheel 305 has self-locking property, which can ensure the stability of the test chamber body 101 during the lifting process.

[0047] All standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail in this application.

[0048] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
