The utility model effectively improves the sealing performance of the sealing ring and avoids the leakage condition caused by the increase of the pressure in the joint.
Description
Technical Field
The utility model relates to the field of sealing rings, in particular to a structure for a joint sealing ring.
Background
The conventional VDA connector is mainly used for connecting automobile pipeline plugs. A sealing ring and a compression ring are generally arranged in the VDA joint. The cross section of a sealing ring in the conventional VDA connector is generally circular, the sealing ring is extruded to realize sealing after an insertion part is inserted, but when the sealing ring is subjected to overlarge liquid pressure, liquid breaks through the contact surface of the sealing ring, and the leakage condition is caused.
Therefore, there is a need for an improved structure that overcomes the above-mentioned deficiencies.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a sealing ring structure for a joint, which effectively improves the sealing performance of the sealing ring and avoids the leakage caused by the increase of pressure in the joint.
The technical purpose of the utility model is realized by the following technical scheme: the utility model provides a be used for connecting sealing washer structure, includes the sealing washer main part, sealing washer main part inside wall integrated into one piece has the sealing, the sealing cross-section is the slope setting, be formed with between sealing and the sealing washer main part and hold the liquid material and drive the sealing and contradict in the ring cavity of inserted part.
The utility model is further configured as follows: the sealing part is inclined towards the center of the sealing ring main body along the insertion direction of the insertion part.
The utility model is further provided with: and one end of the sealing ring main body, into which the insertion part is inserted, is provided with a chamfer guiding the insertion part.
The utility model is further provided with: the sealing washer main part lateral wall is provided with the bellying, the bellying is cyclic annular setting.
The utility model is further provided with: the sealing ring main body and the sealing part are made of elastic materials.
The utility model is further provided with: the included angle between sealing washer main part and the sealing portion is convex setting.
In conclusion, the utility model has the following beneficial effects:
when the plug-in connector is used, the plug-in connector is assembled in the inner cavity of the connector, and when the plug-in component is inserted into the connector, the sealing part abuts against the side wall of the plug-in component and generates certain elastic deformation, so that the sealing effect is achieved; in addition, when the liquid pressure in the inner cavity of the joint is increased, namely the liquid pressure in the annular cavity is also increased, the sealing part is driven to extrude towards the direction of the insertion part, so that the further sealing effect is achieved, and the leakage condition caused by the increase of the liquid pressure is avoided.
The insertion part is guided conveniently through the chamfer, the insertion part is conveniently inserted into the connector correctly, and the use convenience is improved.
The bulge is additionally arranged on the outer side wall of the sealing ring main body, so that the sealing ring main body is fully abutted against the joint inner wall, and a gap between the sealing ring main body and the joint inner wall is effectively sealed.
The connecting surface of the inner side wall between the sealing ring main body and the sealing part is arc-shaped, so that the connecting strength between the sealing part and the sealing ring main body is improved.

fig. 2 is a schematic view of the utility model assembled to a joint.
The corresponding part names indicated by the numbers in the figures: 1. a seal ring main body; 2. a sealing part; 3. an annular cavity; 4. chamfering; 5. a raised portion.
Detailed Description
In order to make the technical means, the original characteristics, the achieved purposes and the effects of the utility model easy to understand, the utility model is further described with reference to the figures and the specific embodiments.
As shown in fig. 1 and 2, the sealing ring structure for a joint according to the present invention includes a sealing ring main body 1, a sealing portion 2 is integrally formed on an inner side wall of the sealing ring main body 1, a cross section of the sealing portion 2 is inclined, and the sealing portion 2 is inclined toward a center of the sealing ring main body 1 from an insertion direction of an insertion member. The seal ring main body 1 and the seal part 2 are made of elastic materials, and rubber and the like can be selected. An annular cavity 3 for accommodating liquid substances and driving the sealing part 2 to abut against the insertion part is formed between the sealing part 2 and the sealing ring main body 1.
When the sealing device is used, the sealing device is assembled in the inner cavity of the joint, and when the insertion part is inserted into the joint, the sealing part 2 is abutted against the side wall of the insertion part and generates certain elastic deformation, so that a sealing effect is achieved; in addition, when the liquid pressure in the joint inner cavity is increased, namely the liquid pressure in the annular cavity 3 is also increased, the sealing part 2 is driven to be extruded towards the direction of the inserted part, so that the further sealing effect is achieved, and the leakage condition caused by the increase of the liquid pressure is avoided.
The end of the seal ring body 1 into which the insert member is inserted is provided with a chamfer 4 for guiding the insert member. The insertion part is guided conveniently through the chamfer 4, the insertion part is conveniently inserted into the joint correctly, and the use convenience is improved.
The outer side wall of the sealing ring main body 1 is provided with a boss part 5, and the boss part 5 is annularly arranged. The bulge part 5 is additionally arranged on the outer side wall of the sealing ring main body 1, so that the sealing ring main body 1 is fully abutted against the joint inner wall, and the gap between the sealing ring main body 1 and the joint inner wall is effectively sealed.
In this embodiment, an included angle between the seal ring main body 1 and the sealing portion 2 is arc-shaped. That is, the connection surface of the inner side wall between the seal ring main body 1 and the seal part 2 is arc-shaped, so that the connection strength between the seal part 2 and the seal ring main body 1 is improved.
