[0002] An oil seal is usually an annular sealing element mainly used for sealing a rotating shaft to prevent leakage of liquids such as lubricating oil and grease on the shaft, and at the same time, it can also prevent external dust and impurities from entering the shaft. An oil seal is generally made of an elastic material such as rubber and has a lip structure that can deform to a certain extent with the rotation of the shaft, thereby achieving a good sealing effect. Before the oil seal is put into use, a radial force tester is required to test its radial force. However, the prior art has the following deficiencies in use:

[0003] The operation screen on the radial force tester is often directly exposed. When the radial force tester is not in use, the operation screen will also be directly in contact with the external air. After a long time, a large amount of dust will adhere to the surface of the operation screen, which may affect the operation sensitivity when the operation screen is used again later.

[0004] Therefore, there is an urgent need for an automatically calibrated radial force tester to solve the above problems. Summary of the Utility Model

[0005] The purpose of the present utility model is to address the problem that the operation screen on the existing radial force tester is often directly exposed. When the radial force tester is not in use, the operation screen will also be directly in contact with the external air. After a long time, a large amount of dust will adhere to the surface of the operation screen, which may affect the operation sensitivity when the operation screen is used again later.

[0032] As Figures 1-5 shown, an automatic calibration radial force tester proposed in this embodiment includes a radial force tester body 1. The radial force tester body 1 includes an operation screen 2. A sealing gasket 3 is fixedly connected to the front of the radial force tester body 1. Four sliding rods 4 are fixedly connected to the front of the radial force tester body 1. A transparent dust-proof cover 5 is provided on the four sliding rods 4. Through the combined use of the transparent dust-proof cover 5 and the sealing gasket 3, a good dust-proof effect can be achieved on the operation screen 2 of the radial force tester body 1. Rectangular openings 6 are provided on both the left and right sides of the transparent dust-proof cover 5. Symmetrically distributed fixing plates 7 are fixedly connected to the front of the radial force tester body 1. A spring 8 is fixedly connected to the side wall of the fixing plate 7. One end of the spring 8 far from the fixing plate 7 is fixedly connected to a connecting plate 9. A rectangular clamping block 10 is fixedly connected to the side wall of the connecting plate 9. A connecting frame 11 is fixedly connected to the bottom of the connecting plate 9. Pull the two connecting frames 11 in the direction away from each other. Drive the two connecting plates 9 and the two rectangular clamping blocks 10 to move through the two connecting frames 11. A guide rod 12 is fixedly connected to the connecting plate 9. The guide rod 12 moves along with the connecting plate 9. Symmetrically distributed limit stop blocks 13 are fixedly connected to the front of the radial force tester body 1. When the two rectangular clamping blocks 10 are disengaged from the two rectangular openings 6, the transparent dust-proof cover 5 can be directly removed from the four sliding rods 4.

[0033] As Figure 1 shown, support legs 14 are installed at the four corners of the bottom of the radial force tester body 1. Rubber sheaths 15 are sleeved on the support legs 14. Place the radial force tester body 1 on the workbench. The rubber sheaths 15 can increase the friction with the workbench, making the radial force tester body 1 more stable when placed and not easy to move.

[0034] As Figure 1 and Figure 2As shown, a transparent dust cover 5 is sleeved outside the operation screen 2. The transparent dust cover 5 is closely attached to the sealing gasket 3. By using the transparent dust cover 5 and the sealing gasket 3 in combination, it can achieve a good dust-proof effect on the operation screen 2 on the radial force tester body 1.

[0035] As Figure 1 , Figure 3 and Figure 5 shown, two rectangular clamping blocks 10 are respectively inserted into two rectangular openings 6, and the transparent dust cover 5 is fixed by the two rectangular clamping blocks 10.

[0036] As Figure 3 shown, the guide rod 12 movably penetrates the fixed plate 7 and can guide the connecting plate 9 when it moves.

[0037] As Figure 3 shown, the connecting plate 9 is in contact with the limit stop block 13. At this time, the end of the rectangular clamping block 10 away from the connecting plate 9 is inserted into the rectangular opening 6 to fix the transparent dust cover 5.

[0038] As Figure 2 and Figure 4 shown, the sliding rod 4 penetrates the sealing gasket 3.

[0039] In this application, the model of the radial force tester body 1 is MZ-4022, which is a known prior art product, and its specific usage method and working principle will not be elaborated here.

[0040] Specifically, when this automatic calibration radial force tester is in use: when it is necessary to use the radial force tester body 1 to test the oil seal, the staff pulls the two connecting frames 11 in the direction away from each other. By driving the two connecting plates 9 and the two rectangular clamping blocks 10 through the two connecting frames 11, when the two rectangular clamping blocks 10 are disengaged from the two rectangular openings 6, the transparent dust cover 5 is directly removed from the four sliding rods 4. When the radial force tester body 1 is no longer in use, the staff pulls the two connecting frames 11 in the direction away from each other again, causing the two springs 8 to be compressed and deformed, increasing the distance between the two rectangular clamping blocks 10. Then, the transparent dust cover 5 is placed on the four sliding rods 4, making the transparent dust cover 5 in contact with the sealing gasket 3 for preliminary positioning of the transparent dust cover 5. Then, the two connecting frames 11 are released, and the elastic force of the spring 8 drives the connecting plate 9 to move towards the transparent dust cover 5. When the connecting plate 9 is in contact with the limit stop block 13, the end of the rectangular clamping block 10 away from the connecting plate 9 is inserted into the rectangular opening 6, thereby fixing the transparent dust cover 5. By using the transparent dust cover 5 and the sealing gasket 3 in combination, it can achieve a good dust-proof effect on the operation screen 2 on the radial force tester body 1. At the same time, it can also protect the operation screen 2 when the radial force tester body 1 is not in use, preventing the staff from accidentally touching the operation screen 2.

[0041] The above embodiments are only used to illustrate the present invention rather than to limit the technical solutions described in the present invention. Although the present specification has described the present invention in detail with reference to the above various embodiments, the present invention is not limited to the above specific embodiments. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and their improvements that do not depart from the spirit and scope of the invention are covered by the scope of the claims of the present invention.
