DETAILED DESCRIPTION
[0026] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.
[0027] Reference Figure 1 and Figure 4 The present invention provides an embodiment of a plastic bucket sealing test device, comprising a test platform 1, an installation frame 2 fixedly connected to the outer wall of the test platform 1, and a cylinder 3 fixedly connected to the outer wall of the installation frame 2, providing a power source, driving a triangular plate 4 to move horizontally within the installation frame 2 through the telescopic movement of the output end, the output end of the cylinder 3 is fixedly connected to the triangular plate 4, converting the horizontal movement of the cylinder 3 into the vertical movement of the slider 5, when the triangular plate 4 moves horizontally, the slider 5 slides along its inclined surface and moves up or down, and a clamping assembly is provided inside the test platform 1;
[0028] The clamping assembly includes a clamp 10, which rotates under the drive of a connecting rod 8 to clamp and release the plastic bucket body 11, ensuring that the bucket body remains stationary during the inspection process. The connecting rod 8 is rotatably connected inside the clamp 10, and rotates around a second rotating shaft 9 under the drive of a rotating rod 7, thereby driving the clamp 10 to rotate. The second rotating shaft 9 is rotatably connected inside the connecting rod 8, and the rotating rod 7 is fixedly connected to the outer wall of the second rotating shaft 9, converting the vertical movement of the slider 5 into the rotational movement of the connecting rod 8. The first connecting shaft 6 is rotatably connected to the inner wall of the rotating rod 7, and the slider 5 is fixedly connected to the outer wall of the first connecting shaft 6. The slider 5 is hinged to the rotating rod 7 through the first connecting shaft 6, transmitting the vertical movement to the rotating rod 7 and driving it to rotate around the first connecting shaft 6.
[0029] Specifically, firstly, the plastic bucket body 11 is placed stably inside the clamp 10. At this time, the cylinder 3 is activated. The extension and retraction of the output end of the cylinder 3 drives the triangular plate 4 to move horizontally inside the mounting frame 2. Since the outer wall of the slider 5 is slidably connected to the inside of the triangular plate 4, the movement of the triangular plate 4 causes the slider 5 to slide on the inclined surface of the triangular plate 4. According to the transmission principle of the inclined surface, the sliding of the slider 5 on the inclined surface is converted into linear movement in the up and down direction. The up and down movement of the slider 5 further drives one end of the rotating rod 7 to rotate. The rotating rod 7 uses the connecting shaft 6 as the pivot point, and its other end drives the connecting rod 8 to rotate around the rotating shaft 9 as the center. The rotation of the connecting rod 8 eventually drives the clamp 10 to rotate synchronously. As the clamp 10 rotates, its inner wall gradually tightens towards the outer wall of the plastic bucket body 11 until the plastic bucket body 11 is stably clamped inside the clamp 10, thereby achieving the effect of fixing the plastic bucket body 11 and providing a stable testing basis for subsequent sealing tests.
[0030] Reference Figures 1-6The fixture 10 contains a plastic bucket body 11. The object to be tested is fixed by the fixture 10 and then inflated by the air pump 23. The inner wall of the plastic bucket body 11 is fixedly connected to the mounting base 21, which serves as the interface for the connecting pipe 22. The mounting base 21 is sealed to the rotating column 12 via the locking block 20. The outer wall of the mounting base 21 is fitted with the rotating column 12, which serves as the connection hub between the connecting pipe 22 and the plastic bucket body 11. The connecting pipe 22 is also allowed to rotate via the rotating sleeve 17. The outer wall of the rotating column 12 is fixedly connected to the connecting pipe 22, which connects the air pump 23 to the plastic bucket body 11 and transmits the test gas to ensure airtightness. The air pump 23 is located outside the test platform 1 and injects gas into the plastic bucket body 11. The airtightness of the bucket is determined by the pressure change. The output end of the air pump 23 is fixedly connected to one end of the connecting pipe 22. The mounting base 21 contains a connecting component, which includes the locking block 20. The connecting pipe 22 and the plastic bucket body 11 are locked and unlocked by sliding. When the locking block 20 is inserted into the mounting base 21, the connecting pipe 22 is fixed. When the locking block 20 retracts the rotating column 12, the connecting pipe 22 is detachable. The outer wall of the locking block 20 is slidably connected to the inside of the mounting base 21. A rotating plate 19 is slidably connected to the outer wall of the locking block 20. It rotates under the drive of the rotating sleeve 17. The rotational motion is converted into linear sliding of the locking block 20 through the arc-shaped sliding groove. A lower toothed plate 18 is fixedly connected to the outer wall of the rotating plate 19. The rotating sleeve 17 is fixedly connected to the outer wall of the lower toothed plate 18. The lower toothed plate 18 is driven to rotate by manual rotation, which in turn drives the rotating plate 19 to rotate. A sliding sleeve 16 is provided above the rotating sleeve 17. An upper toothed plate 15 is fixedly connected to the inner wall of the sliding sleeve 16. Engaging with the lower toothed plate 18, a telescopic rod 13 is fixedly connected to the outer wall of the connecting shaft 16. A spring 14 is sleeved on the outer wall of the telescopic rod 13 to provide a restoring force. When the sliding sleeve 16 is pulled, the spring 14 is compressed and stores energy. When released, it pushes the upper toothed plate 15 to return to its original position. The outer wall of the triangular plate 4 is slidably connected to the inner wall of the mounting frame 2. The cylinder 3 is set on one side of the outer wall of the testing table 1. The outer wall of the telescopic rod 13 is fixedly connected to the inner wall of the rotating column 12. A rotating sleeve 17 is rotatably connected to the outer wall of the rotating column 12. One end of the spring 14 is fixedly connected to the outer wall of the upper toothed plate 15, and the other end of the spring 14 is fixedly connected to the inner wall of the rotating column 12. The outer wall of the slider 5 is slidably connected to the inside of the triangular plate 4. The connecting pipe 22 is set above the testing table 1.
[0031] Specifically, the air pump 23 is started, and its output end is fixedly connected to one end of the connecting pipe 22. The compressed gas generated by the air pump 23 continuously fills the plastic bucket body 11 with air through the connecting pipe 22 to perform a sealing test. When the test is completed and the connecting pipe 22 needs to be disassembled, first pull the sliding sleeve 16 upward by hand. The upper toothed plate 15, which is fixedly connected to the inner wall of the sliding sleeve 16, moves upward accordingly until the upper toothed plate 15 and the lower toothed plate 18 are no longer engaged. During this process, the spring 14 sleeved on the outer wall of the telescopic rod 13 is compressed by the upper toothed plate 15 and contracts. When the upper and lower toothed plates are disengaged, the lower toothed plate 18 is no longer compressed by the upper toothed plate. The constraint of plate 15 causes the rotating sleeve 17 to rotate, which in turn drives the lower toothed plate 18, which is fixedly connected to it, to rotate synchronously. The rotation of the lower toothed plate 18 then drives the rotating plate 19 to rotate inside the rotating column 12. Since the outer wall of the locking block 20 is slidably connected to the inside of the rotating plate 19, the rotation of the rotating plate 19 causes the slide rod at one end of the locking block 20 to slide in the arc-shaped groove inside the rotating plate 19, which in turn drives the locking block 20 to slide inside the rotating column 12 and the mounting base 21. When the locking block 20 is completely moved into the inside of the rotating column 12, the locking constraint between the connecting pipe 22 and the mounting base 21 is released, and the connecting pipe 22 can be easily removed, completing the disassembly operation of the connecting pipe 22.
[0032] Working principle: When the plastic bucket sealing test device is needed, the plastic bucket body 11 is first placed inside the clamp 10. The cylinder 3 drives the triangular plate 4 to move inside the mounting frame 2, thereby driving the slider 5 to slide on the inclined surface of the triangular plate 4, and then the slider 5 moves up and down. Finally, the movement of the slider 5 drives one end of the rotating rod 7 to rotate, and at the same time, the other end of the rotating rod 7 drives the connecting rod 8 to rotate around the rotating shaft 9, thereby driving the clamp 10 to rotate, and then the clamp 10 clamps the plastic bucket body 11, achieving the effect of fixing it.
[0033] In addition, by starting the air pump 23, the air pump 23 inflates the plastic bucket body 11 through the connecting pipe 22 to perform a sealing test. When it is necessary to disassemble the connecting pipe 22, first pull the sliding sleeve 16 to move upward, thereby causing the upper toothed plate 15 to move upward and no longer mesh with the lower toothed plate 18. At the same time, the spring 14 above the upper toothed plate 15 is contracted, and then the lower toothed plate 18 is no longer restrained. By driving the rotating sleeve 17, the lower toothed plate 18 is rotated, which in turn causes the rotating plate 19 to rotate inside the rotating column 12. Then, the rotation of the rotating plate 19 causes the sliding rod at one end of the locking block 20 to slide in the arc-shaped sliding groove inside the rotating plate 19, thereby causing the locking block 20 to slide inside the rotating column 12 and the mounting base 21. When the locking block 20 has completely moved into the interior of the rotating column 12, the connecting pipe 22 can be removed, thus achieving the effect of disconnecting the connecting pipe 22.
[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
