[0024] Embodiment 1:

[0025] A low-temperature gasket performance detection device provided by the present application includes a low-temperature box 1; a placement plate 6 is arranged inside the low-temperature box 1, an adsorption mechanism 7 is fixedly installed inside the placement plate 6, and an ejection mechanism 9 is installed at equal intervals inside the adsorption mechanism 7;

[0026] The ejection mechanism 9 includes an electric push rod two 901, a top plate 902 and a top rod 903. The top plate 902 is fixedly installed at the top of the electric push rod two 901, and the top rod 903 is fixedly installed at the top of the top plate 902. The adsorption mechanism 7 includes an air cavity 701, air holes 702 and a connecting pipe 703. The air cavity 701 is opened in the inner cavity of the placement plate 6, the air holes 702 are opened at equal intervals on the surface of the placement plate 6, a connecting pipe 703 is arranged on one side of the air cavity 701, and placement cavities 8 are arranged at equal intervals on the surface of the placement plate 6. The position and size of the placement cavity 8 match the position and size of the extrusion plate 403;

[0027] Specifically, as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, when the device is performing a low-temperature test on the gasket, the operator places the gasket into the inner cavity of the placement cavity 8 on the surface of the placement plate 6. Then, the connecting pipe 703 is connected to an external air pump. By sucking out the gas inside the air cavity 701 through the air pump, suction can be generated inside the air holes 702, thereby fixing the gasket on the surface of the placement plate 6. At this time, the pressure sensor 5 and the extrusion plate 403 at the bottom of the extrusion mechanism 4 are used to detect the extrusion of the gasket. After the device finishes testing the gasket, the operator can turn on the second electric push rod 901 through an external controller. By driving the ejector rod 903 on the top of the top plate 902 upward through the second electric push rod 901, the ejector rod 903 will pass through the air holes 702 to eject the gasket from the inside of the placement cavity 8, thereby quickly removing the tested gasket and further improving the work efficiency and convenience of the operator in placing and removing the gasket.

[0028] Furthermore, refrigeration plates 2 are symmetrically arranged on the inner side of the low-temperature box 1. A temperature sensor 3 is embedded in the inner wall of the low-temperature box 1. An extrusion mechanism 4 is arranged at the inner top of the low-temperature box 1. The extrusion mechanism 4 includes a first electric push rod 401, a downward moving plate 402, an extrusion plate 403, and a load sensor 404. The first electric push rod 401 is fixedly installed at the inner top of the low-temperature box 1. The bottom of the first electric push rod 401 is fixedly installed with the downward moving plate 402. The bottom of the downward moving plate 402 is fixedly installed with extrusion plates 403 at equal intervals. A load sensor 404 is embedded in the extrusion plate 403, and a pressure sensor 5 is embedded in the extrusion plate 403.

[0029] Specifically, as Figure 1 、 Figure 2 shown, when the device is performing a low-temperature test on the gasket, the refrigeration plate 2 is turned on through an external controller to create a low-temperature state inside the low-temperature box 1. When the refrigeration plate 2 performs low-temperature treatment on the inside of the low-temperature box 1, the temperature inside the low-temperature box 1 can be detected through the temperature sensor 3. Then, the temperature inside the low-temperature box 1 is controlled to a preset value to perform a low-temperature test on the gasket. After the gasket is placed on the surface of the placement plate 6, the first electric push rod 401 is turned on through an external controller. By driving the downward moving plate 402 downward through the first electric push rod 401, the extrusion plate 403 is used to extrude the gasket on the surface of the placement plate 6. During the extrusion process, the load sensor 404 and the pressure sensor 5 can be used to detect the performance of the gasket on the surface of the placement plate 6 under low-temperature conditions.

[0030] Working principle: When the device is performing low-temperature detection on the gasket, the refrigeration plate 2 is turned on through an external controller to create a low-temperature state inside the low-temperature box 1. When the refrigeration plate 2 performs low-temperature treatment on the inside of the low-temperature box 1, the temperature inside the low-temperature box 1 can be detected by the temperature sensor 3, and then the temperature inside the low-temperature box 1 is controlled to a preset value to perform low-temperature detection on the gasket. The gasket is placed into the inner cavity of the placement cavity 8 on the surface of the placement plate 6, and then the connecting pipe 703 is connected to an external air pump. By sucking out the gas inside the air cavity 701 through the air pump, suction can be generated inside the air holes 702, thereby fixing the gasket on the surface of the placement plate 6. At this time, the electric push rod 401 is turned on through the external controller, and the lower moving plate 402 is driven to move down by the electric push rod 401, and the gasket on the surface of the placement plate 6 is subjected to extrusion detection by the extrusion plate 403.

[0031] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified and equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
