SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem of providing a sealing ring aiming at the current situation of the prior art.

The technical scheme adopted by the utility model for solving the technical problems is as follows: a sealing ring is proposed, comprising: the sealing body is designed in an open-loop mode, a first connecting portion is arranged at the first end of the sealing body, a second connecting portion is arranged at the second end of the sealing body, the first connecting portion and the second connecting portion are detachably connected, and the first connecting portion and the second connecting portion of the sealing ring main body are connected to enable the sealing body to form a sealed sealing ring.

Compared with the prior art, the utility model has the advantages that: the sealing body is the open-loop design, therefore, open the both ends of sealing body and can directly overlap its epaxial seal groove in, because first connecting portion and second connecting portion can dismantle the connection, treat that the sealing body cover is after the seal groove, can couple together the both ends of sealing body through connecting first connecting portion and second connecting portion and form confined sealing washer, later with the axle insert that overlaps the sealing washer well install in the sealed hole of adversary's piece, utilize the hole to form the ascending extrusion to the sealing washer axial with the fit clearance of axle, thereby make first connecting portion and second connecting portion zonulae occludens, guarantee that the sealing washer plays sealed effect. After long-time use, the sealing washer can be impaired, and when the impaired back of sealing washer, need dismantle impaired sealing washer from axle type part, pull out axle type part from the adversary piece this moment, take apart the junction of first connecting portion and second connecting portion with the hand is light again, later, just can directly dismantle this sealing washer from axle type part, need not to buckle with finger or clip and take out like traditional sealing washer. Therefore, the sealing ring of the utility model makes the replacing process easier and simpler, reduces the labor intensity of operators, and simultaneously keeps the sealing function of the sealing ring.

In the above sealing ring, a first groove is formed in the center of the section of the first connecting portion, a first protrusion is formed in the center of the second connecting portion corresponding to the first groove, and the first groove is matched with the first protrusion. First connecting portion and second connecting portion have been connected together through setting up first recess and first arch for sealed body forms a confined ring, thereby realizes sealed effect.

In the above sealing ring, the cross-sectional area of the first groove at one end far away from the second connecting portion is gradually increased, the cross-sectional area of the end far away from the first connecting portion is gradually decreased, and a necking is arranged at the end face of the first groove close to the first connecting portion. The first protrusion is clamped in the first groove through the necking, so that the first connecting portion and the second connecting portion are connected more tightly.

In the above sealing ring, the two ends of the first groove are respectively provided with a second protrusion and a third protrusion, the first groove is in smooth transition with the second protrusion and the third protrusion, the two ends of the first protrusion are respectively provided with a second groove and a third groove, the first protrusion is in smooth transition with the second groove and the third groove, the second protrusion is matched with the second groove, and the third protrusion is matched with the third groove. Through the cooperation of second arch, third arch and second recess, third recess for the connection of first connecting portion and second connecting portion is inseparabler.

In the above sealing ring, the sealing body, the first connecting portion, and the second connecting portion are integrally made of a rubber material.

Detailed Description

The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.

As shown in fig. 1 and 2, a seal ring according to the present invention includes: the sealing body 1, sealing body 1 are the design of open-loop type, and the first end of sealing body 1 is provided with first connecting portion 2, and the second end of sealing body 1 is provided with second connecting portion 3, and first connecting portion 2 and second connecting portion 3 can be dismantled the connection, and first connecting portion 2, the 3 butt of second connecting portion of sealing washer main part 1 to make sealing body 1 form confined sealing washer.

The center of the end face of the first connecting portion 2 is provided with a first groove 4, the center of the end face of the second connecting portion 3 corresponds to the first groove 4 and is provided with a first protrusion 5, the first groove 4 is matched with the first protrusion 5, the first groove 4 is away from the end cross-sectional area of the second connecting portion 3, the end cross-sectional area of the first protrusion 5 away from the first connecting portion 2 is gradually reduced, and the end face of the first groove 4 close to the first connecting portion 2 is provided with a necking 6.

The both ends of first recess 4 are equipped with second arch 7 and third arch 8 respectively, and first recess 4 and second arch 7 and third arch 8 are smooth transition respectively, and the both ends of first arch 5 are equipped with second recess 9 and third recess 10 respectively, and first arch 5 and second recess 8, third recess 10 are smooth transition respectively, and second arch 7 cooperatees with second recess 9, and third arch 8 cooperatees with third recess 10.
