Description

Technical Field

[0001] The utility model relates to the technical field of rectangular silicone rings, in particular to a sealing tester for rectangular silicone rings. Background Art

[0002] When conducting a sealing test on a rectangular silicone ring, first install the rectangular silicone ring on a sealing test device, then form a pressure difference on the sealing interface by applying reagents or filling with gas, and then carefully observe whether there is leakage on the sealing interface, so as to determine whether the sealing performance of the rectangular silicone ring meets the requirements.

[0003] Manual observation of whether the sealing interface leaks requires the tester to observe the sealing interface all the time, which can easily cause visual fatigue to the tester and affect the accuracy of observation of the sealing interface. In addition, when testing the sealing of the rectangular silicone ring, the amount of gas injected into the chamber is determined only by the operator's experience. If too much gas is injected, the pressure in the chamber will be too high, which will exceed the bearing range of the rectangular silicone ring. In this case, the silicone ring may be over-compressed or deformed, or even damaged, which will not only affect the accuracy of the test, but also may mislead the performance evaluation of the silicone ring. On the contrary, if too little gas is injected, it will not be able to form a sufficient pressure difference to detect the sealing performance of the silicone ring. In this case, even if there is a slight leak in the silicone ring, it will not be detected due to insufficient pressure, which will also lead to inaccurate test results.

[0004] Therefore, a sealing test machine for a rectangular silicone ring is urgently needed to solve the above problems. Utility Model Content

[0022] The feedback mechanism includes a mounting tube 201 fixedly connected to one side of the test box 102, one end of the mounting tube 201 is connected to the test box 102, a connecting tube 202 is fixedly connected to the side wall of the mounting tube 201, a sliding plate 203 is connected to the connecting tube 202 through a telescopic assembly, a first conductive plate 204 is provided on the side of the sliding plate 203 away from the mounting tube 201, a second conductive plate 205 is provided on the bottom wall of the connecting tube 202, a warning light 206 is provided on the end of the connecting tube 202 away from the mounting tube 201, the first conductive plate 204, the second conductive plate 205 and the warning light 206 and the air pump 106 are electrically connected, and a driving mechanism for driving the first conductive plate 204 is provided in the mounting tube 201;

[0023] It should be noted here that: through the setting of the feedback mechanism, under the driving action of the driving mechanism, by observing the warning light 206, the sealing performance of the rectangular silicone ring can be judged intuitively and conveniently, thereby ensuring the accuracy of the sealing test of the rectangular silicone ring while improving the convenience of the tester in judging the sealing performance of the rectangular silicone ring, and also avoiding damage to the rectangular silicone ring or affecting the test accuracy due to excessive or insufficient gas injection into the test box 102.

[0024] See also Figure 2 and Figure 3 The telescopic assembly shown in the figure includes a fixed plate 301 fixedly connected in the connecting tube 202, a telescopic rod 302 is slidably connected to the fixed plate 301, one end of the telescopic rod 302 is connected to the sliding plate 203, a first spring 303 is sleeved on the side wall of the telescopic rod 302, and both ends of the first spring 303 are respectively connected to the fixed plate 301 and the sliding plate 203;

[0025] It should be noted here that: the setting of the telescopic component provides guidance and reset functions for the movement of the sliding plate 203.

[0026] Working principle: When testing the sealing performance of the rectangular silicone ring, firstly, the rectangular silicone ring is sleeved on the side wall of the conical block 105, and the side wall of the conical block 105 is used to abut against the rectangular silicone ring, which not only fixes the rectangular silicone ring, but also avoids interference with the test part of the rectangular silicone ring. When the rectangular silicone ring is sleeved into the conical block 105, the rectangular silicone ring is moved into the test box 102 by pushing the cylinder 104. When the outer wall of the rectangular silicone ring abuts against the conical hole in the test box 102, the pushing of the cylinder 104 is stopped;

[0027] After the rectangular silicone ring is moved into the test box 102, gas is injected into the test box 102 through the air pump 106. As the gas is continuously injected, the first conductive plate 204 on the sliding plate 203 is pushed against the second conductive plate 205 under the driving action of the driving mechanism, thereby connecting the power supply of the warning light 206, so that the warning light 206 is powered on and flashes. After the warning light 206 lights up, the air pump 106 will stop supplying gas, thereby avoiding damage to the rectangular silicone ring or affecting the test accuracy due to excessive or insufficient gas injection into the test box 102;

[0028] When a suitable gas is injected into the test box 102, the pressure is maintained for a period of time. If the warning light 206 continues to light up, it indicates that the sealing performance of the rectangular silicone ring is intact. If the warning light 206 is off, it indicates that the sealing performance of the rectangular silicone ring is insufficient. Therefore, by observing the warning light 206, the sealing performance of the rectangular silicone ring can be judged intuitively and conveniently, thereby ensuring the accuracy of the sealing test of the rectangular silicone ring while improving the convenience of the tester in judging the sealing performance of the rectangular silicone ring.

[0029] Example 2

[0030] See also Figure 3 This embodiment further explains Example 1. The driving mechanism shown in the figure includes a driving plate 501 slidably connected to the mounting tube 201. A slope 502 is provided on the side of the driving plate 501 away from the test box 102. The other end of the telescopic rod 302 slides on the side wall of the slope 502.

[0031] It should be noted here that: through the setting of the driving mechanism, when gas is injected into the test box 102, when the gas injection in the test box 102 reaches the final stage, while the gas injection is still continuing, under the action of the air pressure, the driving plate 501 will be pushed to move away from the test box 102, and when the driving plate 501 and the telescopic rod 302 are against each other, the interaction force on the inclined surface 502 will push the sliding plate 203 at one end of the telescopic rod 302 to move away from the mounting tube 201.

[0032] See also Figure 2 and Figure 3 , the side wall of the inclined surface 502 shown in the figure is polished;

[0033] It should be noted here that: through polishing, the surface roughness is increased and the friction is reduced, thereby improving the transmission efficiency of the inclined surface 502 after being squeezed.

[0034] See also Figure 2 and Figure 3The installation tube 201 shown in the figure is provided with a guide assembly for guiding the movement of the driving plate 501, and the guide assembly includes two guide grooves 601 symmetrically arranged on the inner wall of the installation tube 201, and the two guide grooves 601 are slidably connected with guide plates 602, and the opposite ends of the two guide plates 602 are connected to the driving plate 501;

[0035] It should be noted that the guide assembly is provided to provide a guide and reset function for the movement of the drive plate 501.

[0036] See also Figure 2 and Figure 3 , a reset assembly for resetting the driving plate 501 is provided in the mounting tube 201 shown in the figure, and the reset assembly includes a reset tube 701 fixedly connected to the bottom wall of the mounting tube 201, a reset rod 702 is slidably connected to the reset tube 701, one end of the reset rod 702 is connected to the driving plate 501, the other end of the reset rod 702 is fixedly connected to the reset plate 703, the other side of the reset plate 703 is fixedly connected to the second spring 704, and the other end of the second spring 704 is connected to the bottom wall of the reset tube 701;

[0037] It should be noted here that: by setting the reset component, it is convenient to reset the drive board 501 after the test is completed. At the same time, when the sealing performance of the rectangular silicone ring is insufficient, causing the internal air pressure of the test box 102 to decrease, the reset component will push the drive board 501 to reset.
