Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1 to 5 , in the embodiment of the present utility model, a sealant airtightness detection device includes two support bases 1 horizontally placed on a support surface. A vertical rod 2 is vertically and fixedly connected to the top end of the support base 1. The inner sides of the two vertical rods 2 are rotatably connected to a cylinder body 3 through a rotating shaft. Both ends of the cylinder body 3 are of an open structure. A rotating shaft hole for inserting the protruding disc portion of one end of the rotating shaft is opened on the outer wall of the cylinder body 3 to prevent the separation of the rotating shaft from the rotating shaft hole. A damping rubber pad for increasing the friction between the rotating shaft and the rotating shaft hole is fixedly connected to the inner wall of the rotating shaft hole. A clamping mechanism for clamping or releasing the clamping of the test piece 10 is arranged inside the cylinder body 3;

[0026] An opening and closing mechanism is arranged below one end of the cylinder body 3. The opening and closing mechanism in the open state is used for a glue gun to apply glue to the contact position between the test piece 10 and the clamping mechanism;

[0027] A locking mechanism for pressing the opening and closing mechanism in the closed state is connected to the side of the cylinder body 3;

[0028] A slot 27 for inserting the test piece 10 is opened on the cylinder body 3.

[0029] In this embodiment: when checking the sealing performance of the sealant, the test piece 10 is first inserted into the slot 27 until the insertion end of the test piece 10 is tightly fitted with the inner wall of the cylinder 3, and then the clamping mechanism is driven to effectively clamp the test piece 10. After the test piece 10 is clamped, the sealant is applied to the contact position between the test piece 10 and the clamping mechanism by a glue gun. After the sealant is dried, the opening and closing mechanism is closed and locked by the locking mechanism.

[0030] After locking, pour clean water into the openings at both ends of the cylinder 3 twice, with the openings that are poured with clean water facing upwards. Leave it for a preset time and observe whether the height of the clean water changes, so as to judge the sealing performance of the sealant.

[0031] When pouring clean water for the second time, by pulling the cylinder 3, the cylinder 3 rotates 180 degrees with the rotating shaft as the axis, and under the limiting effect of the damping rubber pad, the cylinder 3 is rotated to a vertical state;

[0032] By pouring clean water on both sides, you can check the sealing performance of the front and back sides of the sealant.

[0033] Please refer to Figure 2 , Figure 3 and Figure 5 The clamping mechanism includes two slide grooves 14 formed on the inner wall of the cylinder 3, the inner wall of the slide groove 14 is slidably connected with a slider 21, and the inner thread of the slider 21 is connected with a driving threaded column 22;

[0034] The end of the driving threaded column 22 is located outside the cylinder 3 and is connected to a synchronous wheel 15. The two synchronous wheels 15 are connected through a synchronous belt 17. One end of the other synchronous wheel 15 is welded with a crank 16 in a "Z" shape structure.

[0035] A movable clamping frame 11 is integrally formed at the end of the slider 21, and a fixed clamping frame 26 is fixedly connected to the inner wall of the cylinder 3. The side of the fixed clamping frame 26 that contacts the test piece 10 is flush with the end surface of the slide groove 14, and the end of the driving threaded column 22 away from the synchronous wheel 15 is rotatably connected to the fixed clamping frame 26.

[0036] In this embodiment: when the test piece 10 is inserted, the opening and closing mechanism is in the open state. When the test piece 10 is in close contact with the inner cavity of the cylinder 3, the crank 16 is rotated, and the crank 16 drives one synchronous wheel 15 to rotate. The synchronous wheel 15 drives another synchronous wheel 15 to rotate simultaneously and in the same direction through the synchronous belt. The two synchronous wheels 15 simultaneously drive the two driving threaded columns 22 to rotate.

[0037] The two driving threaded posts 22 respectively drive the two sliders 21 to move along the sliding grooves 14. The sliders 21 drive the movable clamping frame 11 to move to clamp one end face of the test piece 10, and the other end face of the test piece 10 is in close contact with the fixed clamping frame 26 until the test piece 10 is effectively clamped.

[0038] At this time, use a glue gun to apply sealant at the contact position between the test piece 10 and the inner circumference of the movable clamping frame 11 and fill it for one week. After the sealant is completely dry, first pour clear water into the opening at one end of the cylinder body 3 close to the synchronous pulley 15. At this time, the synchronous pulley 15 is vertically upward.

[0039] Detect the front sealability of the sealant. After the detection is completed, rotate the cylinder body 3 until the cylinder body 3 rotates 180 degrees. The other opening of the cylinder body 3 rotates from vertically downward to vertically upward. After the rotation is completed, pour clear water into this opening again to check the back sealability of the sealant.

[0040] Please refer specifically to Figure 1 、 Figure 2 and Figure 5 The opening and closing mechanism includes a rotating door 6 rotatably connected to the end of the cylinder body 3. A receiving groove 28 for accommodating the edge of the rotating door 6 is provided in the lower part of the inner wall of the cylinder body 3. A rotating seat 12 is fixedly connected to the edge of the rotating door 6. One end of the rotating seat 12 is rotatably connected to a fixed seat 13 fixedly connected to the cylinder body 3.

[0041] In this embodiment: after the sealant is completely dry, pull the rotating door 6 to close until the edge of the rotating door 6 is completely snapped into the receiving groove 28. At this time, rotate the locking mechanism, and the locking mechanism clamps the rotating door 6 to prevent the rotating door 6 from opening under water pressure.

[0042] It should be noted that: extrusion seals are provided at the contact positions between the rotating door 6 and the cylinder body 3, the receiving groove 28, the contact positions between the movable clamping frame 11 and the rotating door 6 and the cylinder body 3, the contact positions between the fixed clamping frame 26 and the cylinder body 3, and the inner side of the slot 27 to eliminate the problem of inaccurate detection caused by insufficient equipment sealability.

[0043] Please refer specifically to Figure 2 and Figure 4 The locking mechanism includes a fixed block 18 fixedly connected to the side wall of the cylinder body 3. A limiting groove 23 is provided at one end of the fixed block 18 close to the cylinder body 3. A sliding plate 20 is slidably connected to the inner wall of the limiting groove 23 up and down. A pressing block 19 is fixedly connected to the top of the sliding plate 20.

[0044] The top of the fixed block 18 is rotatably connected to a locking threaded post 25. The synchronous pulley 15 extends upward through the pressing block 19, and a turning handle 24 is integrally formed on the top of the pressing block 19. The locking threaded post 25 is threadedly connected to the pressing block 19.

[0045] In this embodiment: after the rotating door 6 is closed, by rotating the rotating handle 24, the rotating handle 24 drives the locking threaded column 25 to rotate. At this time, the pressing block 19 threadedly connected to the locking threaded column 25 moves downward, and the pressing block 19 drives the sliding plate 20 to move downward along the limiting groove 23 until the pressing block 19 effectively presses the rotating door 6.

[0046] Please refer specifically to Figure 1 , on the outer wall of the cylinder body 3 at the position symmetrical to the rotating door 6, a first viewing window 7 is embedded, and on the rotating door 6, a second viewing window 9 is embedded. On one side of the first viewing window 7 and the second viewing window 9, millimeter scales 8 are marked.

[0047] In this embodiment: after filling with clear water, observe the coincidence height of the clear water surface and the millimeter scale 8 through the first viewing window 7 and the second viewing window 9, and record it. Then, fill a beaker with clear water having the same height as the filled clear water to complete the setting of the control group. It should be noted that: the evaporation area of the clear water liquid level in the control group should be consistent with the evaporation area of the clear water in the device, and there should be no large error. After standing for a preset time, observe the coincidence position of the liquid level in the control group and the liquid level in the device with the millimeter scale 8 to determine whether there is a liquid leakage phenomenon.

[0048] Please refer specifically to Figure 1 , on one side of the cylinder body 3 close to the locking mechanism, two symmetrically arranged vertical lines 5 are provided. On one side of a vertical rod 2, a transparent disk 4 is fixed, and angular scales are marked on the transparent disk 4.
