DETAILED DESCRIPTION

[0018] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0019] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0020] In the present invention, unless otherwise specified, directions such as "up" and "down" are usually relative to the directions shown in the drawings, or relative to the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "left" and "right" are usually relative to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directions are not used to limit the present invention.

[0021] like Figure 1-3 As shown, the present application provides an aging tester with high pressure relief safety, including a test body 1 and a pressure relief component 2, the pressure relief component 2 includes a sealing block 204 installed on the top of the test body 1, a vent pipe 207 is installed on the top of the sealing block 204, a vent groove 213 is opened inside the vent pipe 207, the vent groove 213 passes through the top of the test body 1, a sealing ball 206 that can move up and down is sleeved on the inner top of the vent pipe 207, and a sealing ring 208 is fixedly connected to the inner wall of the vent pipe 207 near the sealing ball 206, and the sealing ring 208 is made of elastic material.

[0022] The bottom of the sealing ball 206 fits with the inside of the sealing ring 208 , and the outside of the sealing ball 206 fits with the inside of the air release groove 213 .

[0023] The inner wall of the air release pipe 207 is provided with a plurality of movable grooves 209 . The bottom of the sealing ball 206 is fixedly connected with a fixing column 210 . The outer side of the fixing column 210 is fixedly connected with an extension rod 211 adapted to the movable grooves 209 .

[0024] An elastic member 212 is installed at the bottom of the extension rod 211 , and the bottom of the elastic member 212 is fixedly connected to the inner bottom of the moving groove 209 .

[0025] The top of the test body 1 is fixedly connected to two relatively arranged support rods 201, a moving block 202 is installed on the outer side of the support rod 201, one side of the moving block 202 is connected to a fixing bolt 214, a fixing rod 203 is fixedly connected between the two moving blocks 202, the fixing bolt 214 passes through the moving block 202 and is threadedly connected to one side of the support rod 201, a fixing ring 205 is fixedly connected to the top of the sealing ball 206, and the fixing rod 203 is sleeved inside the fixing ring 205.

[0026] When the equipment is in use, the object to be tested is placed inside the test body 1, and then the top of the test body 1 is sealed by the sealing block 204, and finally the test body 1 is opened to allow the object to be tested. After the experiment, the pressure inside the test body 1 needs to be discharged. During the discharge process, the fixing bolt 214 is first taken out from one side of the moving block 202 and the support rod 201, so that the moving block 202 can be moved and adjusted on the outside of the support rod 201, and then the moving block 202 is pulled upward by the staff's hand so that the moving block 202 can be adjusted. The support rod 201 moves upwards, and the fixing rod 203 is connected to the fixing ring 205, so that the fixing rod 203 separates the sealing ball 206 inside the air release pipe 207 when it is pulled upwards. At this time, the air release groove 213 loses its sealing effect, so that the air pressure inside the test body 1 is discharged to the outside of the hand along the air release groove 213. At the same time, when the gas is discharged, the hand of the staff is placed at the position of the moving block 202, and the moving block 202 is at a certain distance from the air release pipe 207, so that the gas will not contact the hand of the staff, thereby improving the safety of the hand.

[0027] When the gas of the sealing ball 206 is discharged, the movable block 202 can be loosened, so that the sealing ball 206 will rebound and reset through the elastic member 212, so that the sealing ball 206 will re-enter the inner top of the vent pipe 207, and the sealing ball 206 will fit with the inside of the sealing ring 208, so that it can be sealed and the sealing performance can be improved. At the same time, when the fixing rod 203 is in use, the sealing ball 206 moves together with the fixing column 210 and the extension rod 211. Through the movement of the sealing ball 206, the four extension rods 211 will move successively inside the movable groove 209, so that the sealing ball 206 can be discharged without falling off, so as to improve the stability. Finally, after the sealing ball 206 is reset, the fixing bolt 214 can be reconnected to the inside of the support rod 201 and the movable block 202 respectively, so that the fixing rod 203 can fix the sealing ball 206 as a whole, so as to achieve the sealing effect inside the equipment.
