[0001] The utility model relates to the technical field of detection devices, in particular to a high-thermal-conductivity silicone gasket sealing performance detection device. Background Art

[0002] Silicone gasket is a gasket made of silicone rubber material. It is widely used in various industries and occasions, such as electronics, automobiles, food processing, medical and other fields, and it has high thermal conductivity.

[0003] Currently, one of the functions of silicone gaskets is to act as a sealing gasket to seal the gap between two independent structures.

[0004] However, in the prior art, workers would preliminarily judge the sealing performance of the silicone gasket by visually observing whether there are cracks on the silicone gasket. This judgment method is not only inefficient but also has low accuracy. Therefore, the utility model proposes a high thermal conductivity silicone gasket sealing performance detection device to solve the above problem. Utility Model Content

[0006] To achieve the above purpose, the utility model provides the following technical solution: a high thermal conductivity silicone gasket sealing performance detection device, the high thermal conductivity silicone gasket sealing performance detection device comprising:

[0007] A mounting base is rotatably connected to one side of the mounting base with two symmetrically arranged mounting disks, one end of one of the mounting disks is fixedly connected to a motor, a liquid storage box is fixedly connected between the two mounting disks, a detection solution is stored in the liquid storage box, and a silicone gasket is inserted at one end of the liquid storage box, an upper pressing plate is sleeved at one end of the silicone gasket, a purple litmus paper is slidably inserted at one end of the upper pressing plate, a baffle for limiting the movement of the purple litmus paper is inserted and fixed at one side of the upper pressing plate, a hydraulic cylinder is fixedly connected to one side of the baffle, and the hydraulic cylinder and the two mounting disks are fixedly connected.

[0008] Preferably, two symmetrically arranged vertical plates are fixedly connected to one side of the mounting base, and a shaft rod is fixedly connected to one side of the mounting plate, and the shaft rod and the vertical plates are rotatably plugged.

[0009] Preferably, one end of the shaft rod is fixedly connected to a limiting block, one side of one of the vertical plates is fixedly connected to a fixing plate, the motor and the fixing plate are fixedly connected, a connecting plate is fixedly connected between the two mounting plates, and the hydraulic cylinder and the connecting plate are plugged and fixed.

[0010] Preferably, both ends of the liquid storage box are fixedly connected with fixing rods, and the fixing rods are fixedly connected to the mounting plate.

[0011] Preferably, one side of the baffle is slidably connected to two symmetrically arranged sliders, the end where the slider contacts the baffle is arranged in an "I" shape and springs are fixedly connected between the two sliders and the baffle, and the slider is slidably plugged into the upper pressure plate.

[0012] Preferably, both ends of the upper pressure plate are fixedly connected with connecting rods, and the slider is plugged into the connecting rods after sliding. The side of the baffle is fixedly connected with two convex plates, and the spring is located between the slider and the convex plate and is fixedly connected to both the slider and the convex plate.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The device pushes the baffle and the upper pressure plate to slide through the hydraulic cylinder, so that the upper pressure plate and the liquid storage box clamp and fix the silicone gasket, and then the motor drives the mounting plate to perform periodic forward and reverse movements, so that the solution stored in the liquid storage box and the silicone gasket collide violently. If the sealing performance of the silicone gasket is poor, the solution passing through the silicone gasket will contact the purple litmus paper. If the solution is alkaline, the purple litmus paper will show blue, and if the solution is acidic, the purple litmus paper will show red. On the contrary, if the purple litmus paper does not change color, it proves that the sealing effect of the silicone gasket is good. In this way, the corrosion resistance of the silicone gasket can also be tested at the same time, which is very convenient, and the test results can also be seen clearly and intuitively. This solves the problem that the staff in the prior art preliminarily judge the sealing performance of the silicone gasket by observing with the naked eye whether there are cracks in the silicone gasket, which is not only inefficient but also has low accuracy.

[0020] Embodiment 1, a high thermal conductivity silicone gasket sealing performance detection device, the high thermal conductivity silicone gasket sealing performance detection device comprises: a mounting base 1.

[0021] Specifically, one side of the mounting base 1 is rotatably connected to two symmetrically arranged mounting disks 2, one end of one of the mounting disks 2 is fixedly connected to a motor 13, the motor 13 can control the mounting disk 2 and the components on the mounting disk 2 to perform periodic forward and reverse motions, a liquid storage box 3 is fixedly connected between the two mounting disks 2, the liquid storage box 3 stores a detection solution inside and a silicone gasket 4 is inserted at one end of the liquid storage box 3, the detection solution can be an acidic solution or an alkaline solution, an upper pressure plate 5 is sleeved at one end of the silicone gasket 4, and a purple litmus paper 6 is slidably inserted at one end of the upper pressure plate 5, and the acidic solution encounters the purple litmus paper 6, which will make the purple litmus paper 6 display red The alkaline solution will make the purple litmus paper 6 show blue. If a solution penetrates from the silicone gasket 4 and reacts with the purple litmus paper 6 to change the color of the purple litmus paper 6, it can be proved that the sealing performance of the silicone gasket 4 is poor and does not meet the use requirements. A baffle 7 for limiting the movement of the purple litmus paper 6 is plugged and fixed on one side of the upper pressing plate 5, so that the purple litmus paper 6 can be easily replaced. A hydraulic cylinder 8 is fixedly connected to one side of the baffle 7. The hydraulic cylinder 8 and the two mounting plates 2 are fixedly connected. The hydraulic cylinder 8 can push the baffle 7, the purple litmus paper 6 and the upper pressing plate 5 to slide and then clamp the silicone gasket 4 between the upper pressing plate 5 and the liquid storage box 3.

[0022] In order to facilitate the installation of the mounting plate 2, one side of the mounting base 1 of the present application is fixedly connected to two symmetrically arranged vertical plates 11, and one side of the mounting plate 2 is fixedly connected to an axle rod 21. The axle rod 21 and the vertical plate 11 are rotatably plugged in. The vertical plate 11 can give the mounting plate 2 an installation height, thereby facilitating the rotation of the mounting plate 2, and the axle rod 21 can form support for the mounting plate 2.

[0023] In order to further stabilize the mounting disk 2 and its related components, one end of the shaft rod 21 of the present application is fixedly connected to a limiting block 22, and the limiting block 22 can limit the mounting disk 2 from sliding away from the vertical plate 11. A fixing plate 12 is fixedly connected to one side of one of the vertical plates 11, and the motor 13 and the fixing plate 12 are fixedly connected. The fixing plate 12 can facilitate the installation of the motor 13. A connecting plate 23 is fixedly connected between the two mounting disks 2, and the hydraulic cylinder 8 and the connecting plate 23 are plugged and fixed. The connecting plate 23 can facilitate the installation of the hydraulic cylinder 8.

[0024] In order to facilitate the installation of the liquid storage box 3, both ends of the liquid storage box 3 of the present application are fixedly connected with fixing rods 31, and the fixing rods 31 are fixedly connected to the mounting plate 2, so that the liquid storage box 3 can be fixed between the two mounting plates 2.

[0025] In order to facilitate the hydraulic cylinder 8 to simultaneously control the upper pressure plate 5 to slide up and down, one side of the baffle 7 of the present application is slidably connected to two symmetrically arranged sliders 9, the end where the slider 9 and the baffle 7 contact is arranged in an "I" shape, and a spring 91 is fixedly connected between the two sliders 9 and the baffle 7, and the slider 9 and the upper pressure plate 5 are slidably plugged, so that the slider 9 can be stably slidably installed on the baffle 7, and then the slider 9 will be slidably plugged with the upper pressure plate 5 under the action of the spring 91, so that the baffle 7 can be plugged and fixed with the upper pressure plate 5, and can be separated from each other, so that it is convenient to replace the purple litmus paper 6 and observe the color change of the purple litmus paper 6, and it is more convenient for the upper pressure plate 5 to press the silicone gasket 4.

[0026] In order to better install the slider 9, both ends of the upper pressure plate 5 of the present application are fixedly connected with connecting rods 51. After the slider 9 slides, it is plugged into the connecting rod 51, so that the upper pressure plate 5 can better adapt to the sliding plugging of the slider 9. Two convex plates 71 are fixedly connected to the side of the baffle 7. The spring 91 is located between the slider 9 and the convex plate 71 and is fixedly connected to the slider 9 and the convex plate 71. The convex plate 71 can better install the spring 91.

[0027] During actual implementation, firstly, the hydraulic cylinder 8 is driven to make the baffle plate 7 and the upper pressure plate 5 slide away from the liquid storage box 3, and then the silicone gasket 4 is slidably inserted into the open end of the liquid storage box 3. After the silicone gasket 4 is inserted into the liquid storage box 3, the hydraulic cylinder 8 controls the baffle plate 7 and the upper pressure plate 5 to slide, so that the upper pressure plate 5 presses the silicone gasket 4, thereby ensuring that the silicone gasket 4 can exert its own sealing performance. Then, the motor 13 drives the mounting plate 2 to perform periodic forward and reverse motions, so that the solution in the inner cavity of the liquid storage box 3 and the silicone gasket 4 collide violently. If the sealing performance of the silicone gasket 4 is poor, the solution will penetrate the silicone gasket 4 and contact the purple litmus paper 6 to change the color of the purple litmus paper 6. Otherwise, it proves that the sealing performance of the silicone gasket 4 is good. At the same time, the corrosion resistance of the silicone gasket 4 can also be synchronously tested, which is very convenient.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
