Description

Filter sealing ring

Technical Field

The utility model relates to a sealing washer technical field, concretely relates to filter sealing washer.

Background

In order to improve the sealing performance of the filter, a seal ring is usually provided at an inlet and an outlet of the filter. The contact surface (sealing surface) of the sealing ring of the existing filter adopts a plane design, and when the filter is used, because the plane type sealing ring is in surface contact with the filter base when the filter base begins to contact, the compression of the sealing ring is not in an optimal state, the problem of leakage is easy to occur, and the sealing performance is poor.

SUMMERY OF THE UTILITY MODEL

To the deficiency in the background art, the utility model provides a filter sealing ring.

The utility model adopts the technical proposal that: the utility model provides a filter sealing washer, includes ring type seal body, the inside and outside both sides extension of ring type seal body has the pressure boost tongue, be equipped with in the recess between pressure boost tongue and the pressure boost tongue and increase the bullet double-screw bolt, ring type seal body upper and lower both sides face is equipped with first sealed face, be equipped with the second sealed face that is higher than first sealed face on two upper and lower terminal surfaces of pressure boost tongue, be equipped with sealed bead on the first sealed face.

Furthermore, the ring-shaped sealing body is of a hollow structure.

Furthermore, the corners of the upper side and the lower side of the pressurizing tongue are provided with fillets.

Furthermore, reinforcing ribs are arranged on the surface of the annular sealing body between the pressurizing tongue and the pressurizing tongue at equal intervals.

Furthermore, the annular sealing body, the pressure increasing tongue, the elastic increasing stud, the sealing convex edge and the reinforcing rib are of an integrally formed structure.

Further, the heights of the sealing convex edge and the second sealing surface are in the same horizontal plane.

The utility model has the advantages that: the utility model discloses a set up and increase the elasticity performance that the tongue and increase the bullet double-screw bolt increased the sealing washer, improve sealed compactness, set up sealed bead simultaneously on first sealed face, improve the frictional resistance between sealing washer and the part, change the face contact originally into line contact, improve the sealing performance of sealing washer, avoid appearing the problem of leaking.

In addition to the above-described objects, features and advantages, the present invention has other objects, features and advantages.

The present invention will be described in further detail below with reference to the accompanying drawings.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Fig. 2 is a schematic cross-sectional view of the present invention.

In FIGS. 1-2: 1. a ring-shaped seal body; 2. a tongue is pressurized; 3. a spring increasing stud; 4. a first sealing surface; 5. a second sealing surface; 6. sealing the convex edge; 7. rounding off; 8. and reinforcing the ribs.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

It should be noted that, if directional indications (such as upper, lower, left, right, front and rear … …) are involved in the embodiment of the present invention, the directional indications are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indications are changed accordingly.

The utility model provides a filter sealing ring.

In this embodiment, referring to fig. 1-2, the filter sealing ring includes a circular sealing body 1, a pressurizing tongue 2 extends from the inner side and the outer side of the circular sealing body, an elastic stud 3 is disposed in a groove between the pressurizing tongue and the pressurizing tongue, first sealing surfaces 4 are disposed on the upper side and the lower side of the circular sealing body, second sealing surfaces 5 higher than the first sealing surfaces are disposed on the upper end surface and the lower end surface of the pressurizing tongue, and sealing ribs 6 are disposed on the first sealing surfaces.

Among the above-mentioned technical scheme, increase the elasticity performance of sealing washer through setting up the pressure increasing tongue and increasing the elasticity double-screw bolt, improve sealed compactness, set up sealed bead on first sealed face simultaneously, improve the frictional resistance between sealing washer and the part, change the face contact originally into line contact, improve the sealing performance of sealing washer, avoid appearing the problem of leaking.

Specifically, the annular sealing body is of a hollow structure.

The annular sealing body adopts a hollow structure, so that the material weight is reduced, the cost is reduced, the sealing performance is not improved, and the service life is prolonged.

Specifically, the corners of the upper side and the lower side of the pressurizing tongue are provided with fillets 7; and reinforcing ribs 8 are arranged on the surface of the annular sealing body between the pressurizing tongues at equal intervals.

The mechanical strength and the service life of the sealing ring are improved by arranging the reinforcing ribs.

Specifically, the annular sealing body, the pressure increasing tongue, the elasticity increasing stud, the sealing convex edge and the reinforcing rib are of an integrally formed structure; the heights of the sealing convex ribs and the second sealing surface are in the same horizontal plane.

The skilled person should understand that: although the present invention has been described in accordance with the above embodiments, the inventive concept is not limited to this embodiment, and any modification of the inventive concept will be included in the scope of the patent claims.
