Description

Technical Field

[0001] This application relates to the field of rubber ring testing technology, and in particular to a structure for testing the quality of rubber O-rings. Background Technology

[0002] A rubber O-ring is a circular rubber sealing ring. Because its cross-section is O-shaped, it is called an O-ring. A rubber O-ring is an annular cover composed of one or more parts, fixed to one of the bearing rings or washers and contacting or forming a narrow labyrinth gap with another ring or washer to prevent lubricating oil leakage and foreign object intrusion. It is currently widely used in various mechanical equipment, such as hydraulic and pneumatic transmission systems, machine tools, metallurgical machinery, chemical machinery, engineering machinery, construction machinery, mining machinery, petroleum machinery, and plastics machinery. It functions as a seal under specified temperature, pressure, and different liquid and gas media, whether stationary or in motion.

[0003] Existing rubber O-rings require post-production inspection, but in practice, the wide variety of O-ring specifications makes it difficult to adjust existing inspection equipment to suit the dimensions of the rubber O-rings. Therefore, to address this issue, this application provides a rubber O-ring quality inspection structure. Utility Model Content

[0004] To address the problem that existing testing equipment is inconvenient to adjust according to the size of the rubber O-ring, this application provides a rubber O-ring quality testing structure.

[0005] This application provides a rubber O-ring quality inspection structure, including a base with multiple through holes, a column fixedly connected to the top of the base, multiple symmetrical sliding grooves on the base, a detection support assembly on the top of the base, the detection support assembly including multiple support plates, a guide rod fixedly connected to the bottom of each of the multiple support plates, a movable sleeve on the top of the column, a first fixing plate fixedly connected to the inner side of each of the multiple support plates, multiple second fixing plates fixedly connected at equal intervals on the movable sleeve, multiple connecting rods rotatably connecting the multiple first fixing plates and the multiple second fixing plates, and a lead screw installed on the top of the movable sleeve.

[0006] Preferably, the plurality of support plates are vertically arranged on the top of the base, and the plurality of support plates are equidistantly arranged on the outside of the movable sleeve.

[0007] Preferably, the plurality of support plates are configured as arcs, and the plurality of guide rods are respectively movably engaged inside the plurality of sliding grooves.

[0008] Preferably, the bottom end of the lead screw extends to the inner side of the movable sleeve, and the bottom end of the lead screw is rotatably connected to the top of the column.

[0009] Preferably, a handle is fixedly connected to the top end of the lead screw.

[0010] In summary, this application includes the following beneficial technical effects:

[0011] By designing a support assembly for testing rubber O-rings, the following method is employed: rotating a handle drives a lead screw, which in turn moves a movable sleeve up and down. Multiple connecting rods then adjust the positions of several support plates, allowing the rubber O-ring to be placed on these plates. The lead screw again moves the movable sleeve up and down, causing the connecting rods to move the support plates, thus supporting the rubber O-ring for testing. This also facilitates the observation of any cracks in the O-ring. Compared to existing technologies, this design allows for the testing of rubber O-rings of different sizes, and simultaneously assesses both strength and the presence of cracks, effectively improving testing results.

[0017] The following is in conjunction with the appendix Figure 1 - Figure 4 This application will be described in further detail.

[0018] Example:

[0019] A rubber O-ring quality inspection structure, used for rubber O-ring quality inspection, with reference to... Figure 1 - Figure 2The device includes a base 1, which facilitates the installation of various components. The base 1 has multiple through holes 2 for easy fixation. A column 3 is fixedly connected to the top of the base 1, which facilitates the installation of the testing support assembly 5. Multiple sliding grooves 4 are symmetrically provided on the base 1, which facilitates the movement of the subsequent testing support assembly 5. The testing support assembly 5 is located on the top of the base 1, which facilitates the support testing of the rubber O-ring. This testing allows for both the testing of the strength of the rubber O-ring and the testing of its internal and external surfaces.

[0020] In use, the base 1 is fixed through multiple through holes 2, and the rubber O-ring is supported and tested through the testing support component 5. On the one hand, the strength of the rubber O-ring can be tested, and on the other hand, the inside and outside of the rubber O-ring can be tested to observe whether there are any signs of damage.

[0021] Reference Figure 3 - Figure 4 The detection support assembly 5 includes multiple support plates 6, which are arc-shaped and vertically mounted on the top of the base 1. These support plates 6 facilitate support for the rubber O-rings. Guide rods 7 are fixedly connected to the bottom of each support plate 6, and these guide rods 7 are movably engaged within multiple sliding grooves 4. The movement of the guide rods 7 within the sliding grooves 4 limits the range of motion of the support plates 6. A movable sleeve 8 is located at the top of the column 3. Multiple support plates 6 are equidistantly positioned on the outer side of the movable sleeve 8. First fixing plates 9 are fixedly connected to the inner side of each support plate 6. Multiple second fixing plates 9 are equidistantly fixedly connected to the movable sleeve 8. Plate 10, multiple first fixed plates 9 and second fixed plates 10 are rotatably connected by multiple connecting rods 11, so that when the movable sleeve 8 moves, multiple support plates 6 are moved through multiple connecting rods 11, thereby adjusting the spacing of the support plates 6, so that the support plates 6 can detect rubber O-rings of different sizes. A lead screw 12 is installed on the top of the movable sleeve 8, and the bottom end of the lead screw 12 extends to the inside of the movable sleeve 8. The bottom end of the lead screw 12 is rotatably connected to the top of the column 3, so that the movable sleeve 8 can be raised and lowered by rotating the lead screw 12. A handle 13 is fixedly connected to the top of the lead screw 12, and the lead screw 12 is rotated by rotating the handle 13.

[0022] During testing, the device is first adjusted according to the size of the rubber O-ring. The screw 12 is rotated by rotating the handle 13, which in turn drives the movable sleeve 8 to rise and fall. Then, with the cooperation of multiple connecting rods 11, the positions of multiple support plates 6 are adjusted. At this time, the rubber O-ring is placed on the multiple support plates 6. The movable sleeve 8 is raised and lowered again by the screw 12, which in turn drives the connecting rods 11 to move the support plates 6. The multiple support plates 6 support the rubber O-ring, thereby testing the structural strength of the rubber O-ring and facilitating the observation of whether there are cracks in the rubber O-ring.

[0023] This application embodiment discloses a rubber O-ring quality inspection structure. The working principle is as follows: In use, the base 1 is first fixed through multiple through holes 2. Then, the device is adjusted according to the size of the rubber O-ring. Rotating the handle 13 drives the lead screw 12 to rotate, causing the lead screw 12 to move the movable sleeve 8 up and down. Then, with the cooperation of multiple connecting rods 11, the positions of multiple support plates 6 are adjusted. At this time, the rubber O-ring is placed on the multiple support plates 6. Again, the lead screw 12 drives the movable sleeve 8 to move up and down, causing the connecting rods 11 to move the support plates 6. The multiple support plates 6 support the rubber O-ring, thereby detecting the structural strength of the rubber O-ring and facilitating the observation of whether the rubber O-ring has cracks.

[0024] The foregoing description, with reference to preferred embodiments, illustrates an exemplary implementation of a rubber O-ring quality inspection structure provided by this disclosure. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, the protection scope of which is determined by the appended claims.
