Description

Technical Field

[0001] The present invention belongs to the technical field of ceramic detection technology, and particularly relates to a vacuum leak detection device for sanitary ceramic materials. Background Art

[0002] One of the keys to ensuring the quality of sanitary ceramic products is to strictly control the internal gas leakage. The traditional detection method injects helium gas into the ceramic from the flush button through a vacuum leak detection device for sanitary ceramic materials, and uses a pressure sensor to detect whether gas enters the trap from the water storage area in the toilet area. Finally, the detection status is presented through a detector.

[0003] However, during the detection by the traditional detection method, since the pressure sensor is attached to the top of the toilet area, it is not easy to detect the helium gas reaching the trap in time. Moreover, since the pressure sensor of the traditional vacuum leak detection device for sanitary ceramic materials is exposed outside, after long-term use, dust will adhere to the surface of the pressure sensor, resulting in a decrease in the detection efficiency of the pressure sensor. Summary of the Invention

[0004] In view of the problems in the prior art that it is not easy to detect whether there is air leakage at the trap of the ceramic because the pressure sensor is located at the top of the ceramic, and since the pressure sensor of the traditional vacuum leak detection device for sanitary ceramic materials is exposed outside, after long-term use, dust will adhere to the surface of the pressure sensor, resulting in a decrease in the detection efficiency of the pressure sensor, the present invention proposes the following technical solutions:

[0009] Preferably, a mounting box is fixedly connected to the top end inside the lifting platform. A second spring is fixedly connected to the inner wall of the mounting box. One end of the second spring is fixedly connected with a second cable. A limiting block is slidably connected to the surface of the second cable. The limiting block is fixedly connected to the central position inside the mounting box. The second cable passes through the inside of the limiting block. The other end face of the second cable is fixedly connected with a second mounting block. A limiting ring is fixedly connected to the bottom end of the second mounting block. The limiting ring is slidably connected to the outside of the housing of the detection structure.

[0010] Preferably, a plurality of rollers are rotatably connected to the bottom end of the mounting box. Both the first cable and the second cable are wound around the outer surface of the rollers.

[0011] Preferably, a rotating structure is arranged inside the lifting platform;

[0012] The rotating structure includes a gear set meshed with the surface of the first gear. A second gear is meshed with the surface of the gear set. A connecting rod is fixedly connected to the surface of the second gear. The other end of the connecting rod is fixedly connected with a third gear. A rack is meshed with the surface of the third gear. The rack is fixedly connected to the surface of the vacuum leak detector.

[0013] Preferably, a mounting seat is fixedly connected to the middle position at the top end of the threaded block. A lubricating oil bottle is fixedly connected to the top end of the mounting seat.

[0021] The beneficial effects of the present invention are as follows:

[0022] (1) When the pressure sensor is in use, it will descend into the interior of the product. When the pressure sensor moves to the water trap of the sanitary toilet, it detects the air in the water trap area, improving the detection efficiency of the pressure sensor. When not in use, it is retracted inside the lifting platform, effectively avoiding the pressure sensor being exposed outside, resulting in dust adhering to the surface and affecting the detection efficiency of the pressure sensor.

[0023] (2) The pitch of gear two is twice that of gear one. When gear two rotates one circle, gear one will rotate two circles, enabling the two threaded blocks to quickly coincide, and further enabling the leak detection structure to quickly move to the bottom inside the product for detection, thus improving the detection efficiency of the leak detection structure.

[0024] (3) When using the bidirectional lead screw, lubricating oil is dripped on the surface of the bidirectional lead screw, making the bidirectional lead screw more smooth during use, avoiding the problem of wear of the bidirectional lead screw caused by the lack of lubricating oil protection during long-term use, and thus improving the service life of the bidirectional lead screw.

Detailed implementation manners

[0036] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0037] Embodiment 1

[0038] The present invention provides a vacuum leak detection device for sanitary ceramic materials, as Figures 1 to 10As shown in the figure, it includes a vacuum leak detection device for sanitary ceramic materials, which includes: a vacuum leak detector 1. A hydraulic rod 2 is provided at the top of the vacuum leak detector 1. A vacuum pump 3 is provided inside the vacuum leak detector 1. On one side of the hydraulic rod 2, a detector screen is installed and fixedly connected to the top of the vacuum leak detector 1. The bottom end of the hydraulic rod 2 is fixedly installed with a lifting platform 4. The lifting platform 4 is slidably connected inside the vacuum leak detector 1. A leak detection structure 5 is provided inside the lifting platform 4;

[0039] The leak detection structure 5 includes a detection structure housing 51 slidably connected inside the lifting platform 4. At the bottom end inside the detection structure housing 51, a first spring 52 is fixedly connected. At the top end of the first spring 52, a conical block 53 is fixedly connected. At the top end of the conical block 53, a baffle 54 is fixedly connected. At the top end of the baffle 54, a connecting column 55 is fixedly connected. The connecting column 55 is slidably connected inside the detection structure housing 51. At the outer top end of the detection structure housing 51, a plurality of rotating blocks 56 are fixedly connected. The outer side of the rotating block 56 is rotatably connected with a connecting block 57. At the bottom end of the connecting block 57, a pressure sensor 58 is installed.

[0040] As Figures 4 to 6 shown in the figure, a lifting structure 6 is provided at the top end of the detection structure housing 51;

[0041] The lifting structure 6 includes a first mounting block 61 fixedly connected to the top end of the detection structure housing 51. Inside the first mounting block 61, a first cable 62 is installed. The other end of the first cable 62 is fixedly installed with a clamping ball 63. The outer side of the clamping ball 63 is clamped and connected with a buckle 64. The bottom end of the buckle 64 is fixedly connected with a threaded block 65. Inside the threaded block 65, a bidirectional lead screw 66 is rotatably connected. One end face of the bidirectional lead screw 66 is fixedly connected with a first gear 67. The first gear 67 is rotatably connected inside the lifting platform 4. The number of the threaded blocks 65 is set to two, which are respectively located at both ends of the bidirectional lead screw 66. At the top end of a single threaded block 65, two buckles 64 are provided, and the two buckles 64 are respectively located at both ends of the threaded block 65. By rotating the first gear 67 and driving the two threaded blocks 65 to approach and separate, the process of raising and lowering the detection structure housing 51 is completed. Through the clamping of the buckle 64 to the clamping ball 63, the problem of the first cable 62 falling off is avoided, and the stability of the lifting structure 6 is improved.

[0042] As Figure 4 、 Figure 5 、 Figure 6 and Figure 9As shown in the figure, a mounting box 7 is fixedly connected to the inner top end of the lifting platform 4. A second spring 8 is fixedly connected to the inner wall of the mounting box 7. One end of the second spring 8 is fixedly connected to a second cable 9. A limiting block 10 is slidably connected to the surface of the second cable 9. The limiting block 10 is fixedly connected to the center position inside the mounting box 7. The second cable 9 passes through the inside of the limiting block 10. The other end surface of the second cable 9 is fixedly connected to a second mounting block 11. A limiting ring 12 is fixedly connected to the bottom end of the second mounting block 11. The limiting ring 12 is slidably connected to the outside of the detection structure housing 51. The length of the second cable 9 is shorter than that of the first cable 62. One end of the second cable 9 is provided with a bifurcation. Each single bifurcation is installed inside the second mounting block 11. When the detection structure housing 51 moves downward, it drives the limiting ring 12 to move downward. When the limiting ring 12 moves downward, it drives the second spring 8 to be stretched and deformed, and drives the second cable 9 to move. When one end surface of the second spring 8 approaches the limiting block 10, the movement stops. At this time, the downward movement distance of the limiting ring 12 can be extended. When the detection structure housing 51 retracts, it drives the limiting ring 12 back to its original position, and it sleeves on the surface of the detection structure housing 51 by its own weight. Then, the second spring 8 retracts the excess second cable 9 into the mounting box 7, avoiding the problem that when used again, the excess second cable 9 winds around the surface of the bidirectional lead screw 66, resulting in the bidirectional lead screw 66 being unable to rotate normally.

[0043] As Figure 4 , Figure 5 , Figure 6 and Figure 9 shown, several rollers 13 are rotatably connected to the bottom end of the mounting box 7. Both the first cable 62 and the second cable 9 are wound around the outer surface of the rollers 13. The number of mounting boxes 7 is set to two, and the number of rollers 13 is set to four. The four rollers 13 are evenly installed at the bottom end of the two mounting boxes 7. When the second cable 9 and the first cable 62 move, they rotate inside the rollers 13, and with the assistance of the rollers 13, the pressure on the second cable 9 and the first cable 62 is reduced, avoiding the problem that the second cable 9 and the first cable 62 are overweight and break, thereby increasing the service life of the second cable 9 and the first cable 62.

[0044] As Figure 2 , Figure 3 , Figures 4 to 10 shown, a rotating structure 14 is provided inside the lifting platform 4;

[0045] The rotating structure 14 includes a gear set 141 meshed and connected to the surface of the first gear 67. A second gear 142 is meshed and connected to the surface of the gear set 141. A connecting rod 143 is fixedly connected to the surface of the second gear 142. The other end of the connecting rod 143 is fixedly connected to a third gear 144. A rack 145 is meshed and connected to the surface of the third gear 144. The rack 145 is fixedly connected to the surface of the vacuum leak detector 1. The gear set 141 is composed of multiple gears of the same size. The pitch of the second gear 142 is twice the pitch of the first gear 67. When the second gear 142 rotates one circle, the first gear 67 will rotate two circles, enabling the two threaded blocks 65 to quickly coincide, and further enabling the leak detection structure 5 to quickly move to the bottom inside the product for detection, thereby improving the detection efficiency of the leak detection structure 5.

[0046] As Figure 4 , Figures 6 to 8 shown, a mounting seat 15 is fixedly connected to the middle position at the top of the threaded block 65. A lubricating oil bottle 16 is fixedly connected to the top of the mounting seat 15. A one-way silica gel valve 17 is arranged at the bottom inside the lubricating oil bottle 16. A guiding nozzle 18 is fixedly connected to the bottom of the lubricating oil bottle 16. The guiding nozzle 18 is located above the bidirectional lead screw 66. A lubricating oil collection box 19 is fixedly connected to the bottom of the bidirectional lead screw 66. During the use of the bidirectional lead screw 66, the lubricating oil moves towards the central position inside the lubricating oil bottle 16 and drops onto the surface of the guiding nozzle 18 through the one-way silica gel valve 17. At this time, the lubricating oil slowly drops onto the surface of the bidirectional lead screw 66 through the guiding nozzle 18, and the excess lubricating oil drops into the interior of the lubricating oil collection box 19 for collection, making the bidirectional lead screw 66 more smooth during use, avoiding the problem of wear caused by the lack of lubricating oil protection during the long-term use of the bidirectional lead screw 66, and thereby improving the service life of the bidirectional lead screw 66.

[0047] As Figure 4 and Figure 6 shown, a limiting groove is arranged at the top inside the lifting platform 4. A convex block 20 is slidably connected inside the limiting groove. The convex block 20 is fixedly connected to the top of the threaded block 65. Two convex blocks 20 are arranged at the edge position at the top of a single threaded block 65. During the movement of the two threaded blocks 65, the convex blocks 20 are driven to move synchronously. When the convex blocks 20 move, they slide inside the limiting groove, making the movement process of the threaded block 65 more stable, avoiding the problem of deviation during the movement of the threaded block 65, and thereby improving the stability of the threaded block 65 during movement.

[0048] As Figure 4 Figure, Figure 6 and Figure 7As shown, the number of connecting blocks 57 is set to four. The side of a single connecting block 57 close to the conical block 53 is an inclined surface, and the inclined surface of the connecting block 57 fits the surface of the conical block 53. When the conical block 53 moves upward, the lower surface of the connecting block 57 drives the connecting block 57 to rotate. When the connecting block 57 rotates, it drives the pressure sensor 58 to spread outwards, making the detection range of the pressure sensor 58 larger. Thus, the pressure sensor 58 can quickly detect the air leakage position of the product, improving the detection efficiency of the pressure sensor 58.

[0049] The present invention also provides a method for leak detection using the above-mentioned vacuum leak detection device for sanitary ceramic materials, including the following steps:

[0050] Step 1: Place the ceramic: Place the ceramic inside the vacuum leak detector 1 and block the air holes except the top one.

[0051] Step 2: Detect the ceramic: Start the vacuum leak detector 1 to drive the lifting platform 4 to contact the top of the ceramic. The lifting platform 4 drives the air leakage detection structure 5 to move to the water seal of the sanitary toilet. At this time, the vacuum pump 3 evacuates the toilet part at the bottom of the air leakage detection structure 5.

[0052] Step 3: Then inject pressurized helium gas from the toilet flush button and detect the pressure inside the product through the pressure sensor 58. If there is air leakage, the pressure of the helium gas entering the water seal is small; if there is no air leakage, the pressure of the helium gas entering the water seal is large. Based on this, it is judged whether there is a leakage point in the toilet.

[0053] Step 4: Take out the product: After the detection is completed, the vacuum leak detector 1 drives the lifting platform 4 to move upward. The lifting platform 4 drives the air leakage detection structure 5 to reset, and then the product is taken out from the vacuum leak detector 1 to complete the detection.

[0054] Working principle: During the use of the device, the staff place the product to be detected inside the vacuum leak detector 1, block the air holes of the product except the top, and then start the hydraulic rod 2. The hydraulic rod 2 drives the lifting platform 4 to move downward. When the lifting platform 4 moves downward, it drives the first gear 67 to move downward. When the first gear 67 moves downward, it rotates around its own axis due to the limitation of the rack 145. The rotation of the first gear 67 drives the connecting rod 143 to rotate, the rotation of the connecting rod 143 drives the second gear 142 to rotate, the rotation of the second gear 142 drives the gear set 141 to rotate, the rotation of the gear set 141 drives the first gear 67 to rotate, and the first gear 67 drives the bidirectional lead screw 66 to rotate. When the bidirectional lead screw 66 rotates, it drives the threaded blocks 65 at both ends to move towards the center position. The threaded blocks 65 drive the bumps 20 and the buckles 64 to move synchronously. Due to the limitation between the bumps 20 and the lifting platform 4, the movement of the threaded blocks 65 is more stable. When the buckles 64 move, they drive the ball catches 63 to move synchronously, and the movement of the ball catches 63 drives the first cable 62 to move synchronously. At this time, since the two threaded blocks 65 approach each other, the leak detection structure 5 will drive the first cable 62 to move downward due to its own weight. When the first cable 62 moves downward, it rotates inside the roller 13 to unload the force, preventing the leak detection structure 5 from descending too quickly. Then, when the leak detection structure 5 moves downward, the first spring 52 pushes the conical block 53 upward. The conical block 53 drives the connecting block 57 to fit with the limiting ring 12. Through the connecting block 57 and the limiting ring 12, when the leak detection structure 5 moves downward, it drives the limiting ring 12 to move downward. The limiting ring 12 drives the second cable 9 to move downward. When the distance that the limiting ring 12 moves downward reaches the maximum limit of the second cable 9, the limiting ring 12 stops moving downward. At this time, the second cable 9 drives the limiting ring 12 to hang above the detection structure housing 51, and the leak detection structure 5 continues to move downward. At this time, since the limiting ring 12 leaves the surface of the detection structure housing 51, the first spring 52 drives the conical block 53 upward. When the conical block 53 moves upward, it drives the connecting block 57 to expand outward. The connecting block 57 drives the pressure sensor 58 to expand outward, making the detection range of the pressure sensor 58 wider inside the product. Then, the conical block 53 drives the baffle 54 upward. The upward movement of the baffle 54 drives the connecting column 55 upward. Then, the leak detection structure 5 continues to move downward and stops moving when it is close to the water seal of the sanitary toilet. At this time, the bottom end of the lifting platform 4 is in contact with the top end of the product. Then, the staff start the vacuum pump 3 to make the inside in a vacuum state. Subsequently, pressurized helium gas is injected through the toilet flush button, and the pressure inside the product is detected by the pressure sensor 58. If there is a leak, the pressure of the helium gas entering the water seal is small. If there is no leak, the pressure of the helium gas entering the water seal is large. Based on this, it is judged whether there is a leak point in the toilet. When the detection of the product is completed, reverse the above steps to make the leak detection structure 5 retract into the lifting platform 4, and the connecting column 55 is squeezed by the top end inner wall of the lifting platform 4. At this time, the first spring 52 is compressed, making the connecting block 57 drive the pressure sensor 58 to embed inside the detection structure housing 51.When the pressure sensor 58 is in use, it will descend to the trap inside the product, and the pressure sensor 58 is used to detect the trap, which improves the detection efficiency of the pressure sensor 58. When not in use, it is recycled inside the lifting platform 4, effectively avoiding the exposure of the pressure sensor 58 outside, which may cause dust to adhere to its surface and affect the detection efficiency of the pressure sensor 58;

[0055] When the detection structure housing 51 is recycled inside the lifting platform 4, it drives the limiting ring 12 to be recycled synchronously. At this time, the limiting ring 12 will move downward due to its own gravity and sleeved on the outer surface of the detection structure housing 51, preventing the accidental expansion of the connecting block 57. By recycling the second cable 9, it avoids the problem that when used again, the excess second cable 9 is wound around the surface of the bidirectional lead screw 66, resulting in the inability of the bidirectional lead screw 66 to rotate normally;

[0056] When the threaded block 65 moves, it drives the mounting seat 15 to move. The mounting seat 15 drives the lubricating oil bottle 16, the one-way silica gel valve 17 and the nozzle 18 to move synchronously. At this time, the lubricating oil inside the lubricating oil bottle 16 flows through the one-way silica gel valve 17 into the nozzle 18 and drops onto the surface of the bidirectional lead screw 66 through the nozzle 18. The excess lubricating oil will fall into the lubricating oil collection box 19 for collection, making the bidirectional lead screw 66 more smooth during use and avoiding the problem of wear of the bidirectional lead screw 66 without the protection of lubricating oil during long-term use, thereby improving the service life of the bidirectional lead screw 66.

[0057] The above embodiments are only used to illustrate the technical solutions of the present invention, not to limit it.
