[0026] Embodiment 1

[0027] A metal fluororubber washer includes a fluororubber washer body 1. A ring-shaped groove is formed at the top of the fluororubber washer body 1, and a ring-shaped metal washer 2 is arranged in the ring-shaped groove. A raised pressing part 101 is arranged at the top of the fluororubber washer body 1. The raised pressing part 101 is used to position the ring-shaped metal washer 2 inside the ring-shaped groove. The top of the ring-shaped metal washer 2 is fixedly connected with rivets 3 arranged in a ring array. The rivets 3 are used to assist in connecting the ring-shaped metal washer 2 and an external mechanism.

[0028] A first ring-shaped assembly groove 4 is formed on the inner surface of the fluororubber washer body 1. A ring-shaped raised ring 5 is fixedly connected to the bottom of the fluororubber washer body 1. The ring-shaped raised ring 5 is made of fluororubber material. A second ring-shaped assembly groove 6 is formed between the bottom of the fluororubber washer body 1 and the inner surface of the ring-shaped raised ring 5. The second ring-shaped assembly groove 6 and the first ring-shaped assembly groove 4 are used to assist in connecting the fluororubber washer body 1 and an external mechanism.

[0029] Such as Figure 1 、 Figure 2 and Figure 3, the side of the annular metal washer 2 with the rivet 3 is the front side, and the other side is the back side. When the annular metal washer 2 is located, the fluororubber washer body 1 covers the back side of the annular metal washer 2. When connecting and sealing the metal fluororubber washer to an external mechanism, there are curved surfaces on different external mechanisms corresponding to the first annular fitting groove 4 and the second annular fitting groove 6, so that the external mechanism can be correspondingly attached to the fluororubber washer body 1 to improve the sealing performance. The top of the rivet 3 is a frustum, which is easier to connect with the external mechanism. The convex pressing part 101 is made of fluororubber material. By using the elasticity of the convex pressing part 101 to expand the annular groove, the annular metal washer 2 can be snapped onto the fluororubber washer body 1.

[0030] Compared with the related technology, a metal fluororubber washer provided by the first embodiment of the present invention has the following beneficial effects:

[0031] The present invention uses the elasticity of the convex pressing part 101 to press and position the annular metal washer 2 inside the fluororubber washer body 1, so that the fluororubber washer body 1 covers the back side of the annular metal washer 2, which can improve the corrosion resistance of the annular metal washer 2, absorb shock and vibration, reduce noise, and enhance the anti-galling property, scratch resistance, shock absorption and corrosion resistance of metal parts, etc., making the metal fluororubber washer more durable.

[0032] A cylindrical groove is opened at the bottom of the annular metal washer 2, and a cylindrical convex block 7 is fixedly connected to the bottom of the inner wall of the annular groove and located inside the cylindrical groove.

[0033] Such as Figure 4 and Figure 5 , when the annular metal washer 2 is snapped into the fluororubber washer body 1, the cylindrical convex block 7 can just be snapped into the cylindrical groove at the bottom of the annular metal washer 2.

[0034] Arc-shaped card slots are opened on both sides of the inner wall of the cylindrical groove, and arc-shaped protrusions 8 are fixedly connected to both sides of the cylindrical convex block 7. The arc-shaped protrusions 8 are adapted to the arc-shaped card slots.

[0035] Such as Figure 4 and Figure 5 , during the process of snapping the annular metal washer 2 into the fluororubber washer body 1, the arc-shaped protrusions 8 can expand the cylindrical groove opening, so that when the cylindrical convex block 7 is completely snapped into the cylindrical groove, the arc-shaped protrusions 8 are smoothly snapped into the arc-shaped card slots, further improving the sealing performance between the fluororubber washer body 1 and the annular metal washer 2.

[0036] Rectangular clamping blocks 9 are fixedly connected to both sides of the bottom of the annular metal washer 2 and located on both sides of the cylindrical convex block 7, and rectangular card slots for cooperating with the rectangular clamping blocks 9 are opened at the bottom of the inner wall of the annular groove.

[0037] Such asFigure 4 and Figure 5 When the annular metal washer 2 is snapped into the interior of the fluororubber washer body 1, the rectangular clamping block 9 can be exactly snapped into the rectangular card slot on the fluororubber washer body 1 to assist in clamping the metal washer 2.

[0038] Compared with the related art, a metal fluororubber washer provided in the second embodiment of the present invention has the following beneficial effects:

[0039] When the present invention wraps the annular metal washer 2 with the fluororubber washer body 1, by snapping the arc-shaped protrusion 8 into the arc-shaped card slot and the rectangular clamping block 9 into the rectangular card slot, the clamping ability between the annular metal washer 2 and the fluororubber washer body 1 is improved.

[0040] The bottom of the annular metal washer 2 is fixedly connected with a threaded shaft 10. The bottom of the threaded shaft 10 penetrates through the fluororubber washer body 1 and extends to the outside of the fluororubber washer body 1. The bottom of the threaded shaft 10 is threadedly connected with a locking sleeve 11, and the outer surface of the locking sleeve 11 is fixedly connected with a fluororubber protective sleeve 12.

[0041] Such as Figure 6 , there is an opening on the fluororubber washer body 1 to facilitate the threaded shaft 10 to pass through.

[0042] The bottom of the fluororubber washer body 1 is fixedly connected with a first sealing ring 13, and the fluororubber protective sleeve 12 is fixedly connected with a second sealing ring 14 that is used in cooperation with the first sealing ring 13.

[0043] Such as Figure 6 , when the locking sleeve 11 is threadedly connected with the threaded shaft 10, the first sealing ring 13 and the second sealing ring 14 can be made to fit together to ensure the sealing performance of the bottom of the fluororubber washer body 1.

[0044] Compared with the related art, a metal fluororubber washer provided in the third embodiment of the present invention has the following beneficial effects:

[0045] The present invention passes the threaded shaft 10 through the fluororubber washer body 1 and then threadedly connects it with the locking sleeve 11, so that the annular metal washer 2 can be locked into the interior of the fluororubber washer body 1 to prevent the annular metal washer 2 from loosening and detaching from the interior of the fluororubber washer body 1.

[0046] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
