The technical insufficiency to the aforesaid exists, the utility model aims at providing a sealing washer for special type vehicle hydraulic tank is last to solve the problem of mentioning in the above-mentioned background art.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a sealing ring used on a hydraulic oil tank of a special vehicle comprises a plate body, wherein the plate body is provided with a first end surface, a second end surface and bolt holes penetrating through the plate body, first ring bodies are symmetrically arranged on the first end surface and the second end surface, and the center line of each first ring body is coincided with the center line of each bolt hole; the inner diameter of the first ring body is smaller than the diameter of the bolt hole, and the outer diameter of the first ring body is larger than the diameter of the bolt hole; a first rectangular sealing frame, a second rectangular sealing frame and a plugging column are arranged on the first end face; the second rectangular sealing frame is located inside the first rectangular sealing frame on the first end face, the first ring body is arranged between the first rectangular sealing frame and the second rectangular sealing frame, and the blocking column is located inside the second rectangular sealing frame on the first end face.
Preferably, the first ring body has a semi-circular cross-sectional shape.
Preferably, the first rectangular sealing frame has a semicircular cross-sectional shape.
Preferably, the cross-sectional shape of the second rectangular sealing frame is a semicircle.
Preferably, the number of the blocking columns is two, and the two blocking columns are arranged at intervals along the length direction of the plate body.
The design of the utility model can effectively solve the problem that the hole reserved on the hydraulic oil tank of the special vehicle and provided with the heater has hydraulic oil leakage; the sealing effect is better, the occurrence of faults caused by the oil leakage problem of the hydraulic oil tank of the special vehicle is reduced, the times of maintenance are reduced, and the service life of the hydraulic oil tank of the special vehicle is prolonged.
Drawings
Fig. 1 is a schematic perspective view of the present invention;
FIG. 2 is a rear view of FIG. 1;
fig. 3 is an installation diagram of the present invention.
Wherein:
1. a first rectangular sealing frame; 2. a plate body; 3. a second rectangular sealing frame; 4. a first ring body; 5. bolt holes; 6. a first end face; 7. plugging the column; 8. a second end surface.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1 to 3, a seal ring for a hydraulic oil tank of a special vehicle includes a plate body 2, the plate body 2 is configured with a first end surface 6, a second end surface 8 and bolt holes 5 penetrating through the plate body 2, and four bolt holes 5 are provided and are respectively located at four corners of the plate body 2; the first end surface 6 and the second end surface 8 are symmetrically provided with a first ring body 4, and the center line of the first ring body 4 is superposed with the center line of the bolt hole 5; the inner diameter of the first ring body 4 is smaller than the diameter of the bolt hole 5, and the outer diameter is larger than the diameter of the bolt hole 5; the first end face 6 is provided with a first rectangular sealing frame 1, a second rectangular sealing frame 3 and a plugging column 7; the second rectangular sealing frame 3 is positioned on the first end face 6 in the first rectangular sealing frame 1, the first ring body 4 is arranged between the first rectangular sealing frame 1 and the second rectangular sealing frame 3, and the plugging column 7 is positioned on the first end face 6 in the second rectangular sealing frame 3; penetrating a bolt into the bolt hole 5 from the second end face 8 side of the plate body 2, connecting the bolt with a hole which is reserved on a special vehicle hydraulic oil tank and is used for assembling a heater, and fixing the sealing gasket on the special vehicle hydraulic oil tank; after the bolt is screwed, the first ring body 4 on the first end surface 6 is tightly attached to the head of the bolt, the head of the bolt tightly presses the first ring body 4, so that the first ring body 4 is deformed, and because the inner diameter of the first ring body 4 is smaller than the diameter of the bolt hole 5, the inner side part of the first ring body 4 is pressed into the bolt hole 5 to block a gap between the bolt and the bolt hole 5, and the bolt is tightly matched with the first ring body 4, the inner ring of the first ring body 4 can be ensured to be tightly attached to the thread of the bolt, and oil can not leak out from gaps between the bolt and the first ring body 4 and between the bolt and the bolt hole 5; similarly, the first ring body 4 of the second end surface 8 blocks gaps between the bolts and the bolt holes 5 and gaps between the first ring body 4 and the bolts under the extrusion force of the plate body 2 and a hydraulic oil tank of a special vehicle; the plugging column 7 plugs the assembly heater hole reserved on the hydraulic oil tank of the special vehicle, the first rectangular sealing frame 1 and the second rectangular sealing frame 3 are firmly extruded and pasted on the hydraulic oil tank of the special vehicle to form two seals, and liquid leaked from the reserved assembly heater hole is isolated in the second rectangular sealing frame 3 and in the area between the first rectangular sealing frame 1 and the second rectangular sealing frame 3, so that the liquid cannot leak to the outside.
Further, the first ring body 4 has a semicircular sectional shape.
Further, the cross-sectional shape of the first rectangular sealing frame 1 is semicircular.
