Description
Technical Field
The utility model relates to the technical field of elastic sealing rings, in particular to a reinforced elastic sealing ring.
Background
The elastic sealing ring is applied to a vehicle engine and used for distinguishing engine oil and gasoline, has very high requirement on sealing performance, has very good compensation capability, can timely compensate worn parts after a sealing lip is worn, is in a holding shaft state at any time, and provides a reinforced elastic sealing ring to improve the sealing performance of the elastic sealing ring if the sealing is not good and the engine oil is easy to burn.
Disclosure of Invention
According to the utility model, the middle groove is clamped by the reinforcing piece, so that the middle sealing lip is also in a state of holding the shaft, and the aim of improving the tightness of the elastic sealing ring is fulfilled.
In order to achieve the above purpose, the present utility model adopts the following technical scheme:
A reinforced elastic sealing ring comprises an arc elastic support, a middle groove, a reinforcing rib and a middle sealing lip; the arc elastic support is arranged in the mounting groove, and the middle groove is arranged at the middle position of the sealing ring main body and is annular; the reinforcing ribs are arranged in the middle grooves; the intermediate sealing lip is disposed on the back of the intermediate groove.
Preferably, the through hole is arranged in the axial direction of the sealing ring main body, the whole sealing ring main body is penetrated, the middle positions of the sealing ring main body and the through hole are provided with mounting grooves for mounting the arc-shaped elastic support, and the arc-shaped elastic support is used for compensating the abrasion of the first sealing lip, the second sealing lip and the third sealing lip, so that the worn first sealing lip, the worn second sealing lip and the worn third sealing lip can also well clamp the shaft, and the phenomenon of burning engine oil does not occur.
Preferably, the middle groove is used for installing the reinforcing ribs, and a sealing lip is added in the middle on the basis of the prior art, so that the tightness of the whole elastic sealing ring is improved.
Preferably, the reinforcing rib structure is in a four-leaf grass-shaped outline shape, and the sealing ring main body of the middle groove is removed through middle clamping, so that the middle sealing lip can well clamp the shaft; the outside of strengthening rib and the outer wall of sealing washer main part, install the fixed position on the casing, keep motionless, so the outer edge of strengthening rib and the outer wall parallel and level of sealing washer main part, because the strengthening rib slightly wide with the outer wall of sealing washer main part, so after the installation whole the strengthening rib is in inwards extruded state, can give the compensating force at middle seal lip moment makes it can hold the axle tightly, prevents petrol and engine oil mixing.
Compared with the prior art, the gain effect of the utility model is as follows:
A sealing lip is additionally arranged at the middle position of the elastic sealing ring, and the middle sealing lip is also arranged at the middle position of the elastic sealing ring; the tightness of the elastic sealing ring is improved.

In the figure: a seal ring main body 1; a through hole 2; a mounting groove 3; an arc-shaped elastic support 4; an intermediate tank 5; a reinforcing rib 6; a sealing lip 7; a second seal lip 8; three sealing lips 9; an intermediate seal lip 10;
Detailed Description
The technical scheme of the utility model is further described below with reference to the attached drawings and specific embodiments.
Examples
Referring to fig. 1-5, a reinforced elastic sealing ring comprises an arc-shaped elastic support 4, a middle groove 5, a reinforcing rib 6 and a middle sealing lip 10; the arc elastic support 4 is arranged in the mounting groove 3, and the middle groove 5 is arranged at the middle position of the sealing ring main body 1 and is annular; the reinforcing ribs 6 are arranged in the middle groove 5; the intermediate sealing lip 10 is provided on the back of the intermediate groove 5.
The through hole 2 is arranged in the axial direction of the sealing ring main body 1, the whole sealing ring main body 1 is penetrated, the middle positions of the sealing ring main body 1 and the through hole 2 are provided with the mounting groove 3, the purpose is to mount the arc-shaped elastic support 4, and the arc-shaped elastic support 4 is used for compensating the abrasion of the first sealing lip 7, the second sealing lip 8 and the third sealing lip 9, so that the worn first sealing lip 7, the second sealing lip 8 and the third sealing lip can also well hold the shaft tightly, and the phenomenon of burning engine oil does not occur.
The middle groove 5 is provided with a reinforcing rib 6, and a sealing lip is added in the middle on the original basis, so that the tightness of the whole elastic sealing ring is improved.
The structure of the reinforcing rib 6 is in a four-leaf grass-shaped outline, and the sealing ring main body 1 of the middle groove 5 is clamped in the middle, so that the middle sealing lip can well clamp the shaft; the outside of strengthening rib 6 and the outer wall of sealing washer main part 1, install the fixed position on the casing, keep motionless, so the outer edge of strengthening rib 6 and the outer wall parallel and level of sealing washer main part 1, because strengthening rib 6 slightly wide and the outer wall of sealing washer main part 1, so whole strengthening rib 6 after the installation is in the state of inwards extrudeing, can give the compensating force of middle seal lip 10 moment, makes it can hold the axle tightly, prevents petrol and engine oil mixing.
Working principle: the spring sealing ring is installed, the outer side edge of the reinforcing rib 6 is subjected to extrusion force and is extruded inwards, and then the inner side edge is pressed to extrude the sealing ring main body 1 and the middle sealing lip 10 positioned in the middle, so that the middle sealing lip 10 is tightly held on a shaft in motion at any time, and the shaft is tightly held on one sealing lip 7, the two sealing lips 8 and the three sealing lips 9 on the two sides under the action of the arc-shaped elastic support 4 at any time to seal.
