Abstract
The utility model discloses a rubber sealing ring, which consists of a rubber ring body, a metal framework and a sealing glue layer; the rubber ring is characterized in that the rubber ring body consists of an outer rubber sealing strip, a middle rubber sealing strip, an inner rubber sealing strip and a middle part, a gluing area is preset on the local part of the rubber ring body, the middle rubber sealing strip is arranged at the position of the gluing area, and the inner rubber sealing strip and the middle rubber sealing strip are disconnected at the position of the preset gluing area; a sealing glue layer is coated on the preset gluing area, is bridged with the inner side rubber sealing strip and the middle rubber sealing strip and forms a plurality of completely closed sealing strips together with the outer side rubber sealing strip, so that the sealing function is realized; through in rubber circle body rubber coating region, the liquid rubber of precoating forms the sealing glue layer, and on-the-spot "rubber coating" when replacing current engine spare part equipment is favorable to improving installation efficiency to but the rubber coating volume of accurate control sealed glue improves the product leakproofness.
Description
Technical Field
The utility model relates to an engine seal technical field, specifically say a rubber seal, mainly be applied to the sealed of the complicated sealed operating mode in engine part faying face position, specially adapted sealing strip strides across the sealing of a plurality of parts and the high inconsistent operating mode of adjacent part.
Background
As is well known, a rubber seal ring has excellent sealing characteristics, and is a common sealing part for an engine, and is used for sealing a medium such as lubricating oil or coolant. For some special sealing positions, such as the joint position of two parts, due to the design reason or the processing deviation and other reasons, a certain height difference exists, so that a sealing dead angle is formed, and leakage is easily caused; and the sealing position of the conventional rubber sealing ring is continuous, after local gluing is performed for filling up sealing dead angles, gluing is overlapped with the original rubber ring body, local excessive extrusion of the rubber ring is easily caused after assembly, and adverse effects are caused on sealing performance.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the defects of the prior art and providing a rubber sealing ring.
The utility model provides a technical scheme is: a rubber seal ring is composed of a rubber ring body, a metal framework and a seal glue layer, wherein the rubber ring body and the metal framework are connected into a whole; the rubber ring is characterized in that the rubber ring body consists of an outer rubber sealing strip, a middle rubber sealing strip, an inner rubber sealing strip and a middle part, the inner rubber sealing strip and the outer rubber sealing strip are connected through the middle part, a gluing area is locally preset on the rubber ring body, the middle rubber sealing strip is arranged at the gluing area, and the inner rubber sealing strip and the middle rubber sealing strip are disconnected at the preset gluing area; the preset gluing area is coated with a sealing adhesive layer, the sealing adhesive layer is bridged with the inner side rubber sealing strip and the middle rubber sealing strip of the rubber ring body, and a plurality of complete closed sealing strips are formed together with the outer side rubber sealing strips.
Furthermore, the rubber ring body and the metal framework are connected into a whole by a closed structure which is connected end to form a lubricating oil through hole.
The utility model has the advantages that: 1. when the sealing glue is installed, the sealing glue is filled into a sealing dead angle with excellent flowing characteristic, so that the effect of reliable sealing is achieved, the site gluing process at the position can be cancelled, and the installation efficiency is improved; 2. the rubber ring body is pre-coated with liquid rubber to form a sealing rubber layer, so that the field 'gluing' during assembly of the existing engine parts is replaced, the assembly efficiency is improved, the gluing amount of the sealing rubber layer can be accurately controlled, and the quality stability of products is improved; 3. the rubber ring body is provided with a gluing area in advance, the sealing belt of the gluing area is vacant, after gluing is carried out on the gluing area, the sealing rubber layer is in bridge connection with the rubber ring body to form a complete rubber sealing belt, the problem that the gluing and the original rubber ring body are overlapped and partially extruded due to direct gluing of a common rubber ring can be remarkably solved, and the sealing performance is improved; 4. simple structure, convenient processing, ingenious design, strong practicability and higher popularization value.

In the figure, 1 a rubber ring body, 2 a metal framework, 3 a sealing rubber layer, 4 outer side rubber sealing belts, 5 middle rubber sealing belts, 6 inner side rubber sealing belts, 7 middle parts, 8 gluing areas, 9 first sealing parts, 10 second sealing parts and 11 sealing dead angles.
Detailed Description
For a better understanding and an implementation, the present invention is described in detail below with reference to the accompanying drawings.
As shown in fig. 1, 2, 3 and 4, a rubber seal ring comprises a rubber ring body 1, a metal framework 2 and a sealing adhesive layer 3, wherein the rubber ring body 1 and the metal framework 2 are processed into a whole through a rubber vulcanization process and are of a closed structure in end-to-end connection to form a lubricating oil through hole, and the metal framework 2 plays a role in supporting and fixing the rubber ring body 1; the rubber ring body 1 is composed of an outer rubber sealing strip 4, a middle rubber sealing strip 5, an inner rubber sealing strip 6 and a middle part 7, the inner rubber sealing strip 6 and the outer rubber sealing strip 4 are connected through the middle part 7, a gluing area 8 is locally preset on the rubber ring body 1, the middle rubber sealing strip 5 is additionally arranged in the gluing area 8 except for the inner rubber sealing strip and the outer rubber sealing strip, the rubber sealing strip 6 and the middle rubber sealing strip 5 are disconnected in the gluing area 8, and the outer rubber sealing strip 4 is continuous; the rubber ring sealing structure is characterized in that a sealing rubber layer 3 is coated on a preset rubber coating area 8 through a rubber coating tool, the sealing rubber layer 3 is adhered to the rubber ring body 1 to form the preset rubber coating area 8, the sealing rubber layer 3 is in bridge connection with an inner side rubber sealing strip 6 and an intermediate rubber sealing strip 5 of the rubber ring body 1, and a plurality of complete and closed sealing strips are formed together with an outer side rubber sealing strip 4 to realize a sealing function.
When the rubber sealing ring of the utility model is used, as shown in fig. 4, the first sealing part 9 and the second sealing part 10 are assembled to be different in height, so as to form a sealing dead angle 11; after the sealing glue is installed, the sealing dead angle 11 is filled with the excellent flowing characteristic of the sealing glue, so that the reliable sealing effect is achieved, the operation of on-site gluing can be eliminated, and the installation efficiency is improved; meanwhile, the gluing amount is accurately controlled, and the excessive overflow of gluing is avoided; and the gap of the sealing belt in the gluing area can be preset, so that the problem that the gluing and the local overlapping excessive extrusion of the original rubber ring body caused by the direct gluing of the common rubber ring are obviously improved, and the reliable sealing of the sealing dead angle 11 is ensured.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
