Description

Technical Field

[0001] This application relates to the field of hose inspection, and in particular to a hose inspection sealing fixture. Background Technology

[0002] The main types of hoses include coolant hoses, fuel hoses, air filter connection hoses, refueling hoses, transmission oil cooling hoses, turbocharger hoses, and brake hoses. Most of these hoses carry oil, therefore, they require a high degree of airtightness; leaks are absolutely unacceptable. Thus, a pressure test and leak test must be performed after the hoses are manufactured to ensure they meet airtightness standards.

[0003] Utility model patent CN209446219U discloses a testing fixture for testing the sealing performance of rubber hoses, including an operating table, a vertically arranged back plate on one side of the operating table, a first rubber hose fixing fixture on the operating table, and a second rubber hose fixing fixture on the back plate; the first rubber hose fixing fixture is fixedly mounted on the operating table, and the second rubber hose fixing fixture is slidably mounted on the back plate via a sliding mechanism; both the first and second rubber hose fixing fixtures are provided with multiple locking mechanisms, and the number of locking mechanisms on the first and second rubber hose fixing fixtures is equal.

[0004] One of the aforementioned testing fixtures for hose sealing performance testing uses a first handwheel or a second handwheel to simultaneously rotate multiple locking mechanisms on the first or second hose fixing fixture, thereby adjusting the angle of the locking mechanisms. This facilitates the installation of hoses of different shapes. However, the angles of the multiple locking mechanisms cannot be adjusted individually, making it inconvenient to use when testing multiple hoses of different shapes simultaneously, thus reducing its applicability. Utility Model Content

[0005] To achieve the above objectives, this application provides a hose sealing inspection fixture.

[0006] The sealing fixture for hose inspection provided in this application adopts the following technical solution:

[0007] A hose sealing inspection fixture includes a base and multiple pneumatic plugging heads. The base is equipped with an adjustment assembly for controlling the angle of the pneumatic plugging heads and a fixing assembly for fixing the base. The adjustment assembly includes multiple support plates fixedly connected to the upper surface of the base. An adjustment rod is rotatably connected between every two support plates. A U-shaped frame is fixedly connected to the adjustment rod. The pneumatic plugging head is installed at the top of the U-shaped frame. A first gear is fixedly connected to the adjustment rod inside the U-shaped frame. An electric push rod is provided below each adjustment rod. The electric push rod is installed inside the support plate. A turntable is rotatably connected to the output end of the electric push rod. A transmission rod is fixedly connected to the end of the turntable away from the electric push rod. A second gear is fixedly connected to the transmission rod. The second gear meshes with the first gear. A limiting plate is sleeved between the transmission rod and the second gear and the turntable. A connecting rod is fixedly connected to the side wall of the limiting plate near the electric push rod. The connecting rod is fixedly connected to the support plate.

[0008] By adopting the above technical solution, during use, the angle of the pneumatic filling plug can be adjusted individually by swinging the pneumatic filling plug separately. After adjusting the angle, the electric push rod is activated to push the turntable to move, causing the transmission rod to move laterally and abut against the limiting plate, making it difficult for the turntable to rotate, restricting the rotation of the transmission rod, preventing the second gear from rotating, and locking the first gear to prevent the adjusting rod from rotating, thus fixing the pneumatic filling plug and preventing it from moving. This avoids the problem of multiple locking mechanisms not being able to be adjusted at an angle individually, which would reduce applicability.

[0009] Preferably, the fixing component includes a U-shaped clamp installed on the lower surface of the base, the inner cavity of the U-shaped clamp is provided with a clamping plate, and a threaded rod is rotatably connected to the lower surface of the clamping plate. The end of the threaded rod away from the clamping plate passes through the U-shaped clamp and forms a threaded connection.

[0010] By adopting the above technical solution, the base can be fixed by inserting the U-shaped clamp into the corner of the workbench or tabletop, and then rotating the threaded rod to raise and lower the clamp plate, thereby fixing the U-shaped clamp and preventing the base from shaking during use.

[0011] Preferably, a cylinder is installed at the top of the U-shaped clamp, and the output end of the cylinder is fixedly connected to the lower surface of the base.

[0012] By adopting the above technical solution, the base can be raised and lowered by a cylinder to control the height of the pneumatic plug.

[0013] Preferably, a rotating seat is provided between the cylinder and the U-shaped clamp, the cylinder is fixedly connected to the upper surface of the rotating seat, and the lower surface of the rotating seat is rotatably connected to the U-shaped clamp.

[0014] By adopting the above technical solution, the cylinder can be rotated by rotating the base, thereby adjusting the direction of the pneumatic plug and making it convenient to use.

[0015] Preferably, the upper surface of the rotating seat is provided with a locking bolt, the locking bolt passes through the rotating seat and abuts against the U-shaped clamp, and the locking bolt is threadedly connected to the rotating seat.

[0016] By adopting the above technical solution, rotating the locking bolt can make one end of the locking bolt abut against the U-shaped clamp, which can prevent the rotating seat from rotating and avoid the base from rotating during use.

[0017] Preferably, an elastic rubber pad is fixedly connected to the upper surface of the clamp plate and the inner top of the U-shaped clamp.

[0018] By adopting the above technical solution, the elastic rubber pad can improve the clamping stability of the U-shaped clamp and the clamping plate, and at the same time prevent the U-shaped clamp and the clamping plate from directly contacting the desktop and causing damage to the desktop.

[0019] Preferably, the upper surface of the base is provided with a drive rod, which passes through multiple support plates and forms a rotatable connection. A third gear is fixedly connected to the end of the transmission rod away from the turntable. Multiple fourth gears are fixedly connected to the drive rod, and the fourth gears mesh with the third gears respectively.

[0020] By adopting the above technical solution, rotating the drive rod causes multiple fourth gears to drive multiple third gears to rotate, which in turn drives multiple transmission rods to rotate. At the same time, the angles of multiple pneumatic plugging heads are adjusted. Once the angle of one of the pneumatic plugging heads is adjusted, the electric push rod below the adjusted pneumatic plugging head is activated to push the transmission rod, which disengages the third gear from the fourth gear. This prevents the fourth gear from driving one of the third gears when the drive rod rotates, allowing the angles of the other pneumatic plugging heads to continue to be adjusted, thus improving the angle adjustment efficiency of the pneumatic plugging heads.

[0021] Preferably, the turntable has anti-slip textured edges on the side wall near the limiting plate.

[0022] By adopting the above technical solution, the anti-slip texture can increase the friction between the turntable and the limiting plate, prevent the turntable from rotating, drive the transmission rod to rotate, and improve the stability of the pneumatic plug.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. This application utilizes the coordinated structure of adjusting rod, electric push rod, and transmission rod to allow for individual adjustment of the pneumatic filling plug's angle during use. After the angle is adjusted, the electric push rod is activated to move the turntable, causing the transmission rod to move laterally and abut against the limiting plate. This prevents the turntable from rotating, restricts the transmission rod's rotation, and prevents the second gear from rotating. The first gear is then locked, preventing the adjusting rod from rotating and thus fixing the pneumatic filling plug in place to prevent movement. This design minimizes the problem of multiple locking mechanisms not being able to be adjusted independently, which would reduce applicability.

[0025] 2. By rotating the drive rod, multiple fourth gears drive multiple third gears, which in turn drive multiple transmission rods to rotate. Simultaneously, the angles of multiple pneumatic plugging heads are adjusted. Once one pneumatic plugging head is properly adjusted, activating the electric push rod below it pushes the transmission rod, disengaging the third and fourth gears. This prevents the fourth gear from driving one of the third gears when the drive rod rotates, allowing the angles of the other pneumatic plugging heads to be adjusted further, thus improving the efficiency of pneumatic plugging head angle adjustment.

[0031] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0032] This application discloses a hose sealing inspection tool.

[0033] Reference Figure 1 , Figure 2 and Figure 3 A hose sealing inspection tool includes a base 1 and multiple pneumatic filling plugs 2. The base 1 is provided with an adjustment component for controlling the angle of the pneumatic filling plugs 2 and a fixing component for fixing the base 1. The adjustment component includes a support plate 3, an adjustment rod 4, a U-shaped frame 5, a first gear 6, an electric push rod 7, a turntable 8, a transmission rod 9, a second gear 10, a limit plate 11, and a connecting rod 12.

[0034] Multiple support plates 3 are provided and fixedly connected to the upper surface of the base 1. The multiple support plates 3 are equidistantly distributed and vertically arranged. Multiple adjusting rods 4 are provided and rotatably connected between every two support plates 3. Multiple U-shaped frames 5 are provided and fixedly mounted on the adjusting rods 4. Pneumatic plugs 2 are respectively installed at the top of the U-shaped frames 5. Multiple first gears 6 are provided and fixedly connected to the adjusting rods 4 and located inside the U-shaped frames 5. Multiple electric push rods 7 are provided and located below the adjusting rods 4. The electric push rods 7 are respectively installed inside the support plates 3. Multiple turntables 8 are provided and rotatably connected to the output end of the electric push rods 7. Multiple transmission rods 9 are provided and fixedly connected to the side wall of the turntable 8 away from the electric push rod 7. Multiple second gears 10 are provided and fixedly connected to the transmission rods 9. The second gears 10 mesh with the first gears 6. Multiple limiting plates 11 are provided and located between the second gears 10 and the turntable 8. The limiting plates 11 are sleeved on the transmission rods 9 and fixedly connected to the support plate 3 via connecting rods 12 on the side wall near the electric push rod 7. The thickness of the second gears 10 is greater than that of the first gears 6, so that when the electric push rod 7 drives the transmission rods 9 to move back and forth, the second gears 10 will not disengage from the first gears 6.

[0035] Reference Figure 1 The fixing component includes a U-shaped clamp 13 installed on the lower surface of the base 1. The inner cavity of the U-shaped clamp 13 is provided with a clamping plate 14. A threaded rod 15 is rotatably connected to the lower surface of the clamping plate 14. The end of the threaded rod 15 away from the clamping plate 14 passes through the U-shaped clamp 13 and forms a threaded connection. By inserting the U-shaped clamp 13 into the corner of the workbench or table and then rotating the threaded rod 15, the clamping plate 14 is raised and lowered to fix the U-shaped clamp 13. This can fix the base 1 and prevent the base 1 from shaking during use.

[0036] Reference Figure 1 and Figure 4 A cylinder 16 is installed at the top of the U-shaped clamp 13. The output end of the cylinder 16 is fixedly connected to the lower surface of the base 1. The base 1 can be raised and lowered by the cylinder 16 to control the height of the pneumatic plug 2.

[0037] Reference Figure 1A rotating seat 17 is provided between the cylinder 16 and the U-shaped clamp 13. The cylinder 16 is fixedly connected to the upper surface of the rotating seat 17, and the lower surface of the rotating seat 17 is rotatably connected to the U-shaped clamp 13. The rotating seat 17 can be used to rotate the cylinder 16, thereby rotating the base 1 and adjusting the direction of the pneumatic plug 2 for easy use.

[0038] Reference Figure 1 and Figure 4 The upper surface of the rotating seat 17 is provided with a locking bolt 18. The locking bolt 18 passes through the rotating seat 17 and abuts against the U-shaped clamp 13. The locking bolt 18 is threadedly connected to the rotating seat 17. By rotating the locking bolt 18, one end of the locking bolt 18 can abut against the U-shaped clamp 13, which can prevent the rotating seat 17 from rotating and avoid the base 1 from rotating during use.

[0039] Reference Figure 1 An elastic rubber pad 19 is fixedly connected to the upper surface of the clamping plate 14 and the inner top of the U-shaped clamp 13. The elastic rubber pad 19 can improve the clamping stability of the U-shaped clamp 13 and the clamping plate 14, and at the same time prevent the U-shaped clamp 13 and the clamping plate 14 from directly contacting the table and causing damage to the table.

[0040] Reference Figure 1 and Figure 2 The upper surface of the base 1 is provided with a drive rod 20, which passes through multiple support plates 3 and forms a rotatable connection. The end of the transmission rod 9 away from the turntable 8 is fixedly connected to a third gear 21. The side wall of the support plate 3 near the third gear 21 is provided with a receiving groove for storing the third gear 21. Multiple fourth gears 22 are fixedly connected to the drive rod 20. The fourth gears 22 mesh with the third gears 21 respectively. By rotating the drive rod 20, the multiple fourth gears 22 drive the multiple third gears 21 to rotate, which can drive the multiple transmission rods 9 to rotate. At the same time, the angle of multiple pneumatic plugs 2 is adjusted. When the angle of one of the pneumatic plugs 2 is adjusted, the electric push rod 7 below the pneumatic plug 2 with the adjusted angle is activated to push the transmission rod 9, which can disengage the third gear 21 from the fourth gear 22. When the drive rod 20 rotates, the fourth gear 22 cannot drive one of the third gears 21 to rotate. The angle of the other pneumatic plugs 2 can be adjusted to improve the angle adjustment efficiency of the pneumatic plugs 2.

[0041] Reference Figure 3 The side wall of the turntable 8 near the limiting plate 11 has anti-slip texture 23. The anti-slip texture 23 can increase the friction between the turntable 8 and the limiting plate 11 when they are in contact, prevent the turntable 8 from rotating, drive the transmission rod 9 to rotate, and improve the stability of the pneumatic plug 2.

[0042] The implementation principle of a hose sealing inspection fixture according to an embodiment of this application is as follows: In use, the user first inserts the U-shaped clamp 13 into the corner of the workbench or tabletop, rotates the threaded rod 15 to raise or lower the clamp plate 14, and fixes the U-shaped clamp 13 to the base 1. Then, the height and angle of the base 1 are adjusted by the cylinder 16 and the rotating seat 17. Next, rotating the drive rod 20 causes multiple fourth gears 22 to drive multiple third gears 21 to rotate, which in turn drives multiple transmission rods 9 to rotate, causing the second gear 10 to drive the first gear 6 to rotate, and causing multiple adjusting rods 4 to rotate, thereby simultaneously adjusting the angle of multiple pneumatic plugging heads 2. Once the angle of one of the pneumatic plugging heads 2 is adjusted, the adjusted pneumatic plugging head 2 is activated. The electric push rod 7 below pushes the transmission rod 9, which disengages the third gear 21 from the fourth gear 22. This prevents the fourth gear 22 from driving one of the third gears 21 when the drive rod 20 rotates, allowing for continued adjustment of the angles of the other pneumatic plugs 2. Simultaneously, the turntable 8 abuts against the limiting plate 11, making it difficult for the turntable 8 to rotate and restricting the rotation of the transmission rod 9. This prevents the second gear 10 from rotating and locks the first gear 6, preventing the adjusting rod 4 from rotating. The adjusted pneumatic plugs 2 are then fixed to prevent movement. Finally, one end of the hose is sealed to the pneumatic plug 2, and the hose is tested for a seal. This process minimizes the problem of multiple locking mechanisms not being able to be adjusted individually, which would reduce applicability.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
