Description

Technical Field

[0001] This invention relates to the field of hose airtightness testing technology, and specifically to a novel hose airtightness testing connection tool. Background Technology

[0002] Rubber hoses are a type of tubular rubber product used to transport gases, liquids, slurries, or granular materials. They consist of inner and outer rubber layers and a reinforcing layer. The reinforcing layer can be made of cotton fiber, various synthetic fibers, carbon fiber, asbestos, steel wire, etc. Generally, the inner and outer rubber layers of rubber hoses are made of natural rubber, styrene-butadiene rubber, or cis-butadiene rubber. Oil-resistant rubber hoses use chloroprene rubber or nitrile rubber, while acid- and alkali-resistant and high-temperature resistant rubber hoses use ethylene propylene rubber, fluororubber, or silicone rubber, etc.

[0003] Poor sealing can lead to media leakage, affecting normal function, causing various malfunctions, and contaminating equipment or the environment. Therefore, hoses must undergo airtightness testing after processing. Currently, existing equipment for testing hose airtightness involves connecting one end of the hose to the pipeline of a pressure testing device, while the other end is manually plugged into the hose and secured with a steel wire; then, a pressure test is conducted to determine if the hose passes. This testing method requires manual plug assembly, resulting in low operational efficiency, high labor intensity, and the steel wire can damage the hose. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a novel hose airtightness testing connection fixture with a simple and compact structure that can effectively reduce the labor intensity of employees and improve the efficiency of airtightness testing.

[0005] The present invention provides the following technical solution: a novel hose airtightness testing and connection fixture, comprising: a workbench body, an internal testing pool of the workbench body, a connecting frame at the end of the workbench body away from the testing pool, a movable frame at the outer side of the connecting frame, a rotating frame at the end of the movable frame away from the connecting frame, and multiple sets of connecting components at the outer side of the rotating frame; the movable frame and the connecting frame are connected to the connecting frame via a driving component.

[0006] The connecting assembly is used to quickly connect the hose to the rotating frame for hose inspection.

[0007] The drive assembly is used to drive the connecting frame and the moving frame to operate.

[0008] In this design, the hose is brought into contact with the outer side of the sealing block. Rotating the drive plate causes the rotating rod to shift, allowing the rotatably connected sealing sleeve to move. The sealing sleeve slides to the outer side of the hose. When the hose contacts the inside of the sealing sleeve, it compresses the first sealing ring, which in turn compresses the second sealing ring, thus compressing the first compression spring. The first compression spring, under compression, generates a rebound force, causing the second sealing ring to shift and deform. The deformed first and second sealing rings fit snugly against the outer side of the hose and the inner side of the sealing sleeve, thus increasing the sealing performance of the hose-seal connection. When the sealing sleeve contacts the hose, the second compression spring causes the compression block to shift, allowing it to contact the inner wall of the hose, thus allowing the hose to fit snugly against the inner wall of the sealing sleeve. As the compression block compresses the hose, it comes into contact with a buffer ring. The buffer block cushions the buffer ring, preventing damage to the inner wall of the hose. Gas is introduced into the hose via a delivery channel for airtightness testing.

[0009] Preferably, the connecting assembly comprises a sealing block, a drive plate, a rotating rod, a sealing sleeve, a first sealing ring, a second sealing ring, and a first compression spring. The sealing block is located on the outside of the rotating frame, the drive plate is rotatably connected to the outside of the sealing block, both sets of the rotating rods are rotatably connected to the outside of the drive plate, the sealing sleeve is located at the end of the two sets of rotating rods away from the drive plate, the first sealing ring is located inside the sealing sleeve, the second sealing ring is located outside the first sealing ring and inside the sealing sleeve, and both sets of the first compression springs are located at the end of the second sealing ring away from the first sealing ring and inside the sealing sleeve.

[0010] Preferably, the drive plate has a through groove at one end near the sealing block. The internal structure size of the through groove is designed to correspond to the external structure size of the sealing block. The drive plate is connected to the sealing block through the through groove.

[0011] Preferably, the rotating rod and the sealing sleeve are rotatably connected, the internal structure size of the sealing sleeve is designed to correspond to the external structure size of the sealing block, and the sealing sleeve is located on the outside of the sealing block.

[0012] Preferably, the external structural sizes of the first and second sealing rings correspond to the internal structural sizes of the sealing sleeve, and the first compression spring is connected to the first sealing ring through the second sealing ring.

[0013] Preferably, the sealing sleeve has a fitting ring at the end furthest from the second sealing ring inside, and multiple sets of rubber sealing rings at the outer side of the fitting ring. The sealing sleeve also has a buffer ring at the end furthest from the first sealing ring inside, and the buffer ring is connected to the sealing sleeve through multiple sets of buffer blocks.

[0014] Preferably, two sets of compression blocks are provided on the outer side of the sealing block and inside the sealing sleeve. The outer side of the compression block is designed with an arc shape, and a second compression spring is provided on the compression block extending into the interior of the sealing block. A conveying groove is provided inside the sealing block.

[0015] Preferably, the drive assembly comprises a drive screw, a movable plate, a drive rod, a first bevel gear, a second bevel gear, and a transmission rod. The drive screw is rotatably connected to the inside of the connecting frame and to one end near the movable frame. The movable plate is located at one end of the movable frame near the drive screw. The drive rod is rotatably connected to the outside of the movable frame. The first bevel gear is fixedly connected to one end of the drive rod near the rotating frame. The second bevel gear is meshed with the outside of the first bevel gear. The transmission rod is fixedly connected to the end of the second bevel gear away from the first bevel gear.

[0016] Preferably, the movable plate and the drive screw are threadedly connected, the drive screw extends into the interior of the connecting frame and is fixedly connected to the drive end of the first drive motor, and the connecting frame is provided with a guide plate at one end near the movable plate, and the movable plate and the guide plate are slidably connected.

[0017] Preferably, a second drive motor is provided at one end of the movable frame near the drive rod, the drive end of the second drive motor is fixedly connected to the drive rod, the transmission rod passes through the movable frame and is fixedly connected to the rotating frame, the drive rod is connected to the movable frame through a limiting block, and the drive rod and the limiting block are rotatably connected.

[0018] The beneficial effects of this invention are as follows: Through the design of the connecting assembly, the hose contacts the outer side of the sealing block, and the rotating drive plate drives the rotating rod to move, allowing the rotatably connected sealing sleeve to move. The sealing sleeve slides to the outer side of the hose, and when the hose contacts the inner side of the sealing sleeve, it compresses the first sealing ring, causing the first sealing ring to compress the second sealing ring, thereby compressing the first compression spring. The first compression spring, under compression, generates a rebound force, driving the second sealing ring to move and compressing the first sealing ring, causing deformation. The deformed first and second sealing rings can fit against the outer side of the hose and the inner side of the sealing sleeve, thus increasing the sealing performance of the connection between the sealing sleeve and the hose. When the sealing sleeve contacts the hose, the second compression spring drives the extrusion block to move, allowing the extrusion block to contact the inner wall of the hose, so that the hose can fit against the inner wall of the sealing sleeve. When the extrusion block squeezes the hose, the hose can contact the buffer ring. The buffer block cushions the buffer ring, preventing the extrusion block from damaging the inner wall of the hose. Gas can be introduced into the hose through the delivery channel for airtightness testing. Compared with the traditional clamp connection method for airtightness testing, this device can not only ensure the sealing effect of the hose during airtightness testing, but also greatly improve the efficiency of hose installation and disassembly, and greatly reduce the labor intensity of workers.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example

[0029] like Figures 1 to 7 As shown, a novel hose airtightness testing and connection fixture includes: a workbench body 1, an internal testing pool 2, a connecting frame 3 at the end of the workbench body 1 away from the testing pool 2, a movable frame 4 on the outside of the connecting frame 3, a rotating frame 5 at the end of the movable frame 4 away from the connecting frame 3, and multiple sets of connecting components 6 on the outside of the rotating frame 5. The movable frame 4 and the connecting frame 3 are connected to the connecting frame 3 through a drive component 7.

[0030] The connecting assembly 6 is used to quickly connect the hose to the rotating frame 5 for hose inspection. The connecting assembly 6 consists of a sealing block 8, a drive plate 9, a rotating rod 10, a sealing sleeve 11, a first sealing ring 12, a second sealing ring 13, and a first compression spring 14. The sealing block 8 is located on the outside of the rotating frame 5. The drive plate 9 is rotatably connected to the outside of the sealing block 8. Both sets of rotating rods 10 are rotatably connected to the outside of the drive plate 9. The sealing sleeve 11 is located at the end of the two sets of rotating rods 10 away from the drive plate 9. The first sealing ring 12 is located inside the sealing sleeve 11. The second sealing ring 13 is located outside the first sealing ring 12 and inside the sealing sleeve 11. Both sets of first compression springs 14 are located at the end of the second sealing ring 13 away from the first sealing ring 12 and inside the sealing sleeve 11. The connecting assembly 6 can be used to quickly lock the hose for easy inspection.

[0031] A through groove 15 is provided at one end of the drive plate 9 near the sealing block 8. The internal structure size of the through groove 15 is designed to correspond to the external structure size of the sealing block 8. The drive plate 9 is connected to the sealing block 8 through the through groove 15, and the sealing block 8 is rotatably connected to the through groove 15, so that the sealing block 8 can be connected to the drive plate 9.

[0032] The rotating rod 10 and the sealing sleeve 11 are rotatably connected. The internal structure size of the sealing sleeve 11 is designed to correspond to the external structure size of the sealing block 8, and the sealing sleeve 11 is located outside the sealing block 8. The rotating rod 10 and the sealing sleeve 11 are rotatably connected. The rotating drive plate 9 drives the rotating rod 10 to move, so that the sealing sleeve 11 rotatably connected to it can move.

[0033] The external structural size of the first sealing ring 12 and the second sealing ring 13 is designed to correspond to the internal structural size of the sealing sleeve 11. The first compression spring 14 is connected to the first sealing ring 12 through the second sealing ring 13. The first compression spring 14 can drive the second sealing ring 13 to move and compress the first sealing ring 12 to produce deformation.

[0034] The sealing sleeve 11 has a fitting ring 16 at the end away from the second sealing ring 13 inside, and multiple sets of rubber sealing rings 17 on the outside of the fitting ring 16. The sealing sleeve 11 has a buffer ring 18 at the end away from the first sealing ring 12 inside, and the buffer ring 18 is connected to the sealing sleeve 11 through multiple sets of buffer blocks 19. When the tubing is connected to the sealing sleeve 11, it can contact the fitting ring 16. The fitting ring 16 fits the surface of the tubing and, together with the rubber sealing rings 17, can increase the sealing effect on the tubing.

[0035] Two sets of extrusion blocks 20 are provided on the outer side of the sealing block 8 and inside the sealing sleeve 11. The outer side of the extrusion block 20 has an arc-shaped structure design, and the extrusion block 20 extends into the interior of the sealing block 8 and is provided with a second compression spring 21. The interior of the sealing block 8 is provided with a conveying groove 22, which slides the extrusion block 20 and the sealing block 8, so that the extrusion block 20 can be connected to the second compression spring 21. The second compression spring 21 can drive the extrusion block 20 to move. When the sealing sleeve 11 contacts the hose, the second compression spring 21 drives the extrusion block 20 to move, so that the extrusion block 20 can contact the inner wall of the hose, so that the hose can fit against the inner wall of the sealing sleeve 11. When the extrusion block 20 extrudes the hose, the hose can contact the buffer ring 18. The buffer block 19 buffers the buffer ring 18, so that the buffer ring 18 can buffer the hose and prevent the extrusion block 20 from damaging the inner wall of the hose. The conveying groove 22 can introduce gas into the interior of the hose for airtightness testing.

[0036] The drive assembly 7 is used to drive the connecting frame 3 and the moving frame 4 to operate. The drive assembly 7 consists of a drive screw 23, a moving plate 24, a drive rod 25, a first bevel gear 26, a second bevel gear 27, and a transmission rod 28. The drive screw 23 is rotatably connected to the inside of the connecting frame 3 and to one end near the moving frame 4. The moving plate 24 is located at one end of the moving frame 4 near the drive screw 23. The drive rod 25 is rotatably connected to the outside of the moving frame 4. The first bevel gear 26 is fixedly connected to one end of the drive rod 25 near the rotating frame 5. The second bevel gear 27 is meshed with the outside of the first bevel gear 26. The transmission rod 28 is fixedly connected to the end of the second bevel gear 27 away from the first bevel gear 26. The drive assembly 7 can drive the moving frame 4 and the rotating frame 5 to operate.

[0037] The movable plate 24 is threadedly connected to the drive screw 23. The drive screw 23 extends into the interior of the connecting frame 3 and is fixedly connected to the drive end of the first drive motor. The connecting frame 3 has a guide plate 29 near the movable plate 24. The movable plate 24 and the guide plate 29 are slidably connected. When the movable plate 24 and the drive screw 23 are threadedly connected, the first drive motor is started. The first drive motor can drive the drive screw 23 to rotate, so that the movable plate 24 can be displaced, which in turn drives the movable frame 4 to be displaced. When the movable plate 24 is displaced, the guide plate 29 can guide it to prevent the movable plate 24 from deviating and affecting the displacement of the movable frame 4.

[0038] A second drive motor is provided at one end of the movable frame 4 near the drive rod 25. The drive end of the second drive motor is fixedly connected to the drive rod 25. The transmission rod 28 passes through the movable frame 4 and is fixedly connected to the rotating frame 5. The drive rod 25 is connected to the movable frame 4 through the limiting block 30, and the drive rod 25 and the limiting block 30 are rotatably connected. When the second drive motor is started, the drive rod 25 is driven to rotate, so that the first bevel gear 26 can rotate, which drives the second bevel gear 27 to rotate, thereby enabling the transmission rod 28 to rotate, driving the rotating frame 5 to rotate. The drive rod 25 is rotatably connected to the limiting block 30. When the drive rod 25 rotates, it can be limited by the limiting block 30 to prevent the drive rod 25 from deviating, which would affect the rotation of the rotating frame 5.

[0039] The working principle of this invention is as follows: In actual use, the hose is brought into contact with the outer side of the sealing block 8. The rotating drive plate 9 drives the rotating rod 10 to move, allowing the sealing sleeve 11 connected to it to move. The sealing sleeve 11 slides to the outer side of the hose. When the hose comes into contact with the inside of the sealing sleeve 11, it will compress the first sealing ring 12, causing the first sealing ring 12 to compress the second sealing ring 13, thereby compressing the first compression spring 14. The first compression spring 14 generates a rebound force under compression, driving the second sealing ring 13 to move and compressing the first sealing ring 12 to deform. The deformed first sealing ring 12 and second sealing ring 13 can fit against the outer side of the hose and the inner side of the sealing sleeve 11, thus increasing the sealing performance of the connection between the sealing sleeve 11 and the hose. When the sealing sleeve 11 contacts the hose, the second compression spring 21 drives the compression block 20 to move, allowing the compression block 20 to contact the inner wall of the hose, so that the hose can fit against the inner wall of the sealing sleeve 11. When the compression block 20 presses against the hose... During extrusion, the hose comes into contact with the buffer ring 18. The buffer block 19 cushions the buffer ring 18, preventing the extrusion block 20 from damaging the inner wall of the hose. Gas is introduced into the hose through the delivery channel 22 for air tightness testing. The first drive motor is started, which drives the drive screw 23 to rotate, causing the moving plate 24 to move, which in turn moves the moving frame 4 to the inside of the test tank 2, bringing the hose into contact with the liquid inside. The second drive motor is started, which drives the drive rod 25 to rotate, causing the first bevel gear 26 to rotate, which in turn drives the second bevel gear 27 to rotate, which in turn drives the transmission rod 28 to rotate, which in turn drives the rotating frame 5 to rotate, allowing the hose to rotate. When the hose has poor air tightness, gas will leak out from the inside of the hose and come into contact with the liquid inside the test tank 2, generating bubbles. Therefore, the air tightness of the hose can be quickly tested.

Therefore, the appended claims are intended to be interpreted as including both the preferred embodiments and all changes and modifications falling within the scope of the invention.
