Description

Technical Field

[0001] This utility model belongs to the technical field of rubber gaskets and relates to an oil-resistant rubber gasket. Background Technology

[0002] Rubber gaskets possess properties such as oil resistance, acid and alkali resistance, cold and heat resistance, and aging resistance. They can be directly cut into various shapes of sealing gaskets and are widely used in industries such as pharmaceuticals, electronics, chemicals, antistatic agents, flame retardants, and food. After assembly, rubber gaskets can be used with upper and lower gaskets for protection without affecting their use. However, in actual use, because the outer wall of the rubber gasket is exposed, it is easily affected by external factors, leading to damage from the outside in. After assembly, the damaged areas are not easily observed by the naked eye, thus affecting the subsequent performance. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in the prior art by providing a rubber gasket with protective properties.

[0004] The purpose of this utility model can be achieved through the following technical solution: an oil-resistant rubber gasket, comprising a gasket body, characterized in that the gasket body comprises an upper ring, a middle ring, and a lower ring, which are coaxially arranged; the outer peripheral wall of the middle ring is provided with a plurality of C-shaped pieces arranged along its circumferential direction; annular grooves for facilitating the contact of the upper ring and the middle ring are provided on the end faces where they are in contact; annular grooves are also provided on the end faces where the middle ring and the lower ring are in contact; and the C-shaped pieces are all connected to the upper ring, the middle ring, and the lower ring through connecting units.

[0005] In the aforementioned oil-resistant rubber gasket, the connecting unit is a double-ended stud, and the upper ring, middle ring and lower ring are all provided with mounting grooves for installing the double-ended stud. The mounting grooves on the upper ring and lower ring are arranged in a stepped structure.

[0006] In the aforementioned oil-resistant rubber gasket, the C-shaped sheet is made of an elastic material.

[0007] Compared with existing technologies, this anti-oil corrosion rubber gasket protects the gasket body by setting a C-shaped piece, and the damage to the C-shaped piece is easier to observe. Attached Figure Description

[0008] Figure 1 This is a cross-sectional structural diagram of the anti-oil corrosion rubber gasket.

[0009] In the diagram, 1 is the upper ring; 2 is the middle ring; 3 is the lower ring; 4 is the C-shaped piece; and 5 is the double-ended stud. Detailed Implementation

[0010] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0011] like Figure 1 As shown, this oil-resistant rubber gasket includes a gasket body, which includes an upper ring 1, a middle ring 2, and a lower ring 3. The upper ring 1, middle ring 2, and lower ring 3 are coaxially arranged. Several C-shaped pieces 4 are arranged along the circumference of the outer peripheral wall of the middle ring 2 and form a circle. Annular grooves for the C-shaped pieces 4 are opened on the end faces of the upper ring 1 and the middle ring 2 that are in contact with each other. Annular grooves are also opened on the end faces of the middle ring 2 and the lower ring 3 that are in contact with each other. The above-mentioned annular grooves are all located at the outer edges of the upper ring 1, the middle ring 2, and the lower ring 3. The C-shaped pieces 4 are all connected to the upper ring 1, the middle ring 2, and the lower ring 3 through connecting units, which are double-headed studs 5. Mounting grooves for installing the double-headed studs 5 are opened on the upper ring 1, the middle ring 2, and the lower ring 3. The mounting grooves located on the upper ring 1 and the lower ring 3 are arranged in a stepped structure. The C-shaped pieces 4 are made of elastic material.

[0012] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0013] Although this document uses terms such as "etc." extensively, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this invention; interpreting them as any additional limitation would contradict the spirit of this invention.
