[0022] In addition, it is convenient for the staff to replace the new white sponge after the test. The staff can replace all six white sponges at a time after all are used up, realizing one replacement and six uses. When the white sponge contacts the bottom of the bellows, the bellows can squeeze the white sponge, ensuring that the white sponge is always in a squeezed state when moving along the bellows, thereby improving the contact effect with the bottom of the bellows.

[0046] The fixing unit 2 includes: a U-shaped fixing frame 201 and a connecting bracket 202; there are four U-shaped fixing frames 201, and the four U-shaped fixing frames 201 are slidably installed on the supporting plate 104; a group of limiting circular holes 2011 are respectively opened on the four U-shaped fixing frames 201, and four groups of circular limiting rods 103 are inserted into the four groups of limiting circular holes 2011; the connecting bracket 202 is fixedly installed on the front side of the four U-shaped fixing frames 201; the fixing unit 2 also includes: a limiting clamp ring B203 and a reset spring 204; there are eight limiting clamp rings B203, and the eight limiting clamp rings B203 are fixedly installed on the outside of the four U-shaped fixing frames 201; there are eight reset springs 204, and the eight reset springs 204 are installed on the outside of the four U-shaped fixing frames 201; the rear sides of the eight reset springs 204 are welded to the eight limiting clamp rings B203, and the front sides of the eight reset springs 204 are welded to the supporting plate 104;

[0047] The specific function is as follows: since a group of limiting circular holes 2011 are respectively opened on the four U-shaped fixing frames 201, and the connecting bracket 202 is fixedly installed on the front side of the four U-shaped fixing frames 201, when the bellows 3 to be tested needs to be fixed, the staff inserts the bellows 3 into the four U-shaped fixing frames 201, and then the staff pushes the connecting bracket 202 backwards. At this time, the supporting plate 104 moves downward under the gravity of the bellows 3, so that the four groups of circular limiting rods 103 are inserted into the four groups of limiting circular holes 2011, which limits the four U-shaped fixing frames 201.

[0048] Because the detection vertical plate 106 is fixedly installed on the top of the supporting bottom plate 101, and the detection vertical plate 106 is also slidably connected to the supporting flat plate 104, and a scale line 1061 is set at the top of the detection vertical plate 106, when the leakage of the bellows 3 is serious during the test, the weight of the liquid in the bellows 3 will decrease. At this time, the supporting flat plate 104 will move upward under the action of the four coil springs A105, which is convenient for the staff to know the anti-leakage test results of the bellows 3 through the scale line 1061 and the amount of liquid in the liquid storage box 401, thereby improving the test efficiency and eliminating the need for subsequent testing of the bottom of the bellows 3.

[0049] In the present disclosure, Figure 7 As shown, the liquid filling unit 4 includes: a liquid storage box 401, a fixed frame 402, a liquid suction pump 403 and an L-shaped reinforcement frame 404; the liquid storage box 401 is fixedly installed on the top of the supporting base plate 101; the fixed frame 402 is fixedly installed on the right side of the liquid storage box 401; the liquid suction pump 403 is fixedly installed on the fixed frame 402; the L-shaped reinforcement frame 404 is fixedly installed on the top of the liquid storage box 401; the liquid filling unit 4 also includes: a metal suction tube A405, a metal suction tube B406 and a filling hose 407; one end of the metal suction tube A405 is fixedly installed on the bottom of the liquid suction pump 403, and the other end of the metal suction tube A405 is inserted into the liquid storage box 401; the metal suction tube B406 is fixedly installed on the L-shaped reinforcement frame 404, and the bottom of the metal suction tube B406 is fixedly connected to the liquid suction pump 403; the filling hose 407 is fixedly installed on the top of the metal suction tube B406;

[0050] Its specific function is: because the filling hose 407 is fixedly installed on the top of the metal suction tube B406, and the other end of the metal suction tube A405 is inserted into the liquid storage box 401, and the bottom of the metal suction tube B406 is fixedly connected to the liquid suction pump 403, it is convenient for the staff to add liquid to the bellows 3 to be tested through the liquid suction pump 403 and the filling hose 407; and because the liquid storage box 401 is fixedly installed on the top of the supporting base plate 101, and the liquid storage box 401 is located directly below the bellows 3, it is convenient to recover the liquid in the bellows 3 after the test, thereby realizing the recycling of the liquid.

[0051] In the present disclosure, Figures 8 to 10 As shown, the detection unit 5 includes: an arc-shaped movable plate 501, a movable detection frame 502, a U-shaped handle 503 and a limit baffle A504; the arc-shaped movable plate 501 is slidably mounted on the connecting bracket 202; the movable detection frame 502 is slidably mounted on the arc-shaped movable plate 501; there are two U-shaped handles 503, and the two U-shaped handles 503 are fixedly mounted on the left and right sides of the arc-shaped movable plate 501; the limit baffle A504 is fixedly mounted on the outside of the movable detection frame 502, and The limit baffle A504 is located below the arc movable plate 501; the detection unit 5 also includes: a limit baffle B505, a circular mounting rod 506 and a spiral spring B507; the limit baffle B505 is fixedly installed on the outside of the movable detection frame 502, and the limit baffle B505 is located above the arc movable plate 501; there are two circular mounting rods 506, and the two circular mounting rods 506 are fixedly installed on the top of the arc movable plate 501, and the two circular mounting rods 507 are fixedly installed on the top of the arc movable plate 501. 6 is also slidably connected to the limit baffle B505; there are two coil springs B507, and the two coil springs B507 are installed outside the two circular mounting rods 506, and the two coil springs B507 are located between the arc movable plate 501 and the limit baffle B505; the detection unit 5 also includes: a hexagonal mounting block 508, a limit screw 509 and a white sponge 510; the hexagonal mounting block 508 is rotatably mounted on the movable detection frame 502, and the hexagonal mounting block 5 Six positioning grooves 5081 are provided on the front side of the hexagonal mounting block 508, and six groups of contact openings 5082 are also provided on the hexagonal mounting block 508; a limit screw 509 is threadedly connected to the movable detection frame 502, and the rear end of the limit screw 509 is inserted into the upper positioning groove 5081; six white sponges 510 are provided, and the six white sponges 510 are installed on the hexagonal mounting block 508, and the six white sponges 510 are connected to the hexagonal mounting block 508 by glue;

[0052] Its specific function is as follows: because the arc movable plate 501 is slidably installed on the connecting bracket 202, and the arc movable plate 501 is connected with the connecting bracket 202 by interference fit, and two U-shaped handles 503 are fixedly installed on the left and right sides of the arc movable plate 501, when the value of the scale line 1061 does not change much, the staff can use one of the white sponges 510 to detect whether there is leakage at the bottom of the bellows 3. When the staff pulls the U-shaped handle 503, the movable detection frame 502 drives the six white sponges 510 to move; and because the two coil springs B507 are installed on the outside of the two circular mounting rods 506, and the two coil springs B507 are located between the arc movable plate 501 and the limit rod 506, the two coil springs B507 are located between the arc movable plate 501 and the limit rod 506. When the arc movable plate 501 moves, the upper white sponge 510 can fit tightly with the bottom of the bellows 3 under the action of the two coil springs B507. When the hexagonal mounting block 508 contacts the U-shaped fixing frame 201, the U-shaped fixing frame 201 can push the hexagonal mounting block 508 to move downward. When the hexagonal mounting block 508 is separated from the U-shaped fixing frame 201, the upper white sponge 510 can continue to fit with the bottom of the bellows 3 under the action of the two coil springs B507. When the uppermost white sponge 510 is attached with the test liquid, the leakage test fails. When the uppermost white sponge 510 is not attached with the test liquid, the leakage test passes.

[0053] Since six positioning grooves 5081 are provided on the front side of the hexagonal mounting block 508, and the limit screw 509 is threadedly connected to the movable detection frame 502, and the rear end of the limit screw 509 is inserted into the upper

[0054] The positioning groove 5081 makes it convenient for the staff to replace the new white sponge 510 after the test. The staff can replace all six white sponges 510 at a time after all the six sponges 510 are used, so that one replacement can be used six times. In addition, six groups of contact openings 5082 are provided on the hexagonal mounting block 508. When the white sponge 510 contacts the bottom of the bellows 3, the bellows 3 can squeeze the white sponge 510, ensuring that the white sponge 510 is always in a squeezed state when moving along the bellows 3, thereby improving the contact effect with the bottom of the bellows 3.

[0055] The specific usage and function of this embodiment are as follows:

[0056] When the present invention is used, the support base plate 101 is first installed on the test site by bolts, and then the test liquid is poured into the liquid storage box 401. When the bellows 3 to be tested needs to be fixed, the staff inserts the bellows 3 into the four U-shaped fixing frames 201, and then the staff pushes the connecting bracket 202 backwards. At this time, the support plate 104 moves downward under the gravity of the bellows 3, so that the four groups of circular limiting rods 103 are inserted into the four groups of limiting circular holes 2011, which play a limiting role on the four U-shaped fixing frames 201, thereby realizing the rapid fixation of the bellows 3 to be tested; then the bottom of the bellows 3 is fixed. The end is sealed, and then the filling hose 407 is placed in the bellows 3 to be tested, and then the suction pump 403 is started, so that the staff can add colored liquid to the bellows 3 to be tested through the suction pump 403 and the filling hose 407; when the bellows 3 leaks seriously during the test, the weight of the liquid in the bellows 3 will decrease. At this time, the support plate 104 will move upward under the action of the four coil springs A105, so that the staff can know the anti-leakage test result of the bellows 3 through the scale line 1061 and the amount of liquid in the liquid storage box 401, thereby improving the test efficiency and eliminating the need for subsequent testing of the bellows. The bottom of the bellows 3 is inspected; when the value of the scale line 1061 does not change much, the staff can use one of the white sponges 510 to detect whether there is leakage at the bottom of the bellows 3. When the staff pulls the U-shaped handle 503, the movable detection frame 502 drives the six white sponges 510 to move; when the arc-shaped movable plate 501 moves, the upper white sponge 510 can fit tightly with the bottom of the bellows 3 under the action of the two coil springs B507, and when the hexagonal mounting block 508 contacts the U-shaped fixing frame 201, the U-shaped fixing frame 201 can push the hexagonal mounting block 508 to move downward When the hexagonal mounting block 508 is separated from the U-shaped fixing frame 201, the upper white sponge 510 can continue to fit with the bottom of the bellows 3 under the action of the two coil springs B507. When the white sponge 510 contacts the bottom of the bellows 3, the bellows 3 can squeeze the white sponge 510, ensuring that the white sponge 510 is always in an extruded state when moving along the bellows 3, thereby improving the contact effect with the bottom of the bellows 3. When the uppermost white sponge 510 is attached with the test liquid and changes color, the leakage test fails. When the uppermost white sponge 510 is not attached with the test liquid, the leakage test passes.

[0057] After the test of the bellows 3 is completed, the staff pulls up the two release handles 108. At this time, the four U-shaped fixing frames 201 automatically move forward under the action of the eight reset springs 204, so that the bellows 3 can be quickly removed after the test. Then the water in the bellows 3 is poured into the liquid storage box 401, which is convenient for recovering the liquid in the bellows 3 after the test, thereby realizing the recycling of the liquid; then the staff loosens the limit screw 509, rotates the hexagonal mounting block 508 appropriately, and then tightens the limit screw 509, so that the staff can replace the new white sponge 510 after the test. After all six white sponges 510 are used up, the staff can replace them at one time, thus realizing one replacement and six uses.
