[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0036] Combine the following Figures 1 to 4 , describing an embodiment of the present invention.

[0037] According to an embodiment of the present invention, on the one hand, a multifunctional test device is provided, including: a box body 1, a rotating assembly 5 and a supporting assembly 6. A closed test chamber is provided inside the box body 1, and an air inlet assembly 2 and an air outlet assembly 3 are provided on opposite sides of the box body 1 along the length direction, respectively. A pressurizing assembly 4 is provided on the top of the box body 1, and the pressurizing end of the pressurizing assembly 4 is provided in the test chamber, and a first fixing member is provided on the pressurizing end, and the first fixing member is suitable for being fixedly connected with the top of the sample template. The air inlet assembly 2 and the air outlet assembly 3 are respectively connected to the test chamber, and a plurality of heating plates are also spaced apart in the box body 1. The rotating assembly 5 includes a rotating shaft and a driving member connected to the rotating shaft, and the rotating shaft is provided at the bottom of the box body 1 and is located in the test chamber. The supporting assembly 6 is provided at the top of the rotating shaft, and is suitable for placing the sample mold.

[0038] It can be seen that the multifunctional testing equipment provided by the embodiment of the present invention can conduct tests by introducing various gases into the sample mold in the test chamber of the box 1, applying various pressures to the test, and controlling the test temperature by integrating the air inlet component 2, the air outlet component 3, and the pressurizing component 4 on the box 1. Moreover, by closing the air inlet component 2 and opening the air outlet component 3, the gas in the test chamber can be extracted, so that the test chamber forms a vacuum environment for vacuum testing, which can meet various test conditions and has a wide range of applications. The air inlet component 2 and the air outlet component 3 are arranged on opposite sides of the length direction of the box 1, which is conducive to the ventilation test of the sample mold. The pressurizing component 4 and the supporting component 6 are respectively arranged on the upper and lower sides of the sample mold so as to apply pressure to the sample mold for pressure testing, and the influence on the ventilation test is small. When the pressurizing component 4 is not needed, the rotating component 5 can also drive the supporting component 6 to rotate, so as to drive the sample mold to rotate, so as to facilitate the drying, heating and other tests of the sample.

[0039] Specifically, the air inlet assembly 2 is used to introduce the gas required for the test, such as air, carbon dioxide, nitrogen, argon, etc., into the test chamber. The air outlet assembly 3 is used to discharge the gas in the test chamber. The air inlet assembly 2 is provided with an air inlet, an air inlet valve and an air inlet pump. The air inlet is connected to the test chamber, and the air inlet is connected to the air inlet pump through the air inlet valve. The air inlet pump is used to provide power, and the air inlet valve is used to adjust the gas flow rate introduced into the air inlet.

[0040] Similarly, the gas outlet component 3 is provided with a gas outlet, a gas outlet valve and a gas outlet pump.

The pressure rod is adjusted to move up and down by rotating the regulating valve to adjust the pressure on the sample mold. When the pressure component 4 applies pressure to the sample mold, the sample mold needs to be fixed between the pressure component 4 and the support component 6 in advance. The driving member of the rotating component 5 can be a conventional driving member such as a motor and a cylinder.

[0042] It should be noted that the sample molds in the embodiments of the present invention include but are not limited to pure paste molds and mortar molds for making cement.

[0044] When the sample mold needs to be pressurized, the second fixing part is first installed on the supporting body. The top of the sample mold is connected to the first fixing part, and the bottom is connected to the second fixing part to fix the supporting body. Then the pressurizing component 4 is controlled to apply pressure to the sample mold. The structure is stable and the reliability is strong.

[0045] It should be noted that the embodiment of the present invention does not limit the detachable connection between the support body and the second fixing member, for example, a buckle can be used for quick installation, or a threaded connection can be used for a firm connection. Similarly, the detachable connection between the support body and the rotating shaft is not limited.

[0046] In one embodiment, the support assembly 6 includes a tray detachably mounted on the support body.

The air duct is arranged in the test chamber, and the vacuum pump extracts the gas in the test chamber through the air duct to form a vacuum environment in the test chamber. Of course, other conventional vacuum pumping components can also be selected as needed, and the embodiments of the present invention are not overly limited to this.

[0052] In addition, the vacuum pump can also be connected to the air inlet component 2 and the air outlet component 3.
