Description
Technical Field
The utility model belongs to the technical field of the engine seal, concretely relates to anti-drop's sealing washer.
Background
The O-ring is a rubber seal ring with a circular cross section, and is called an O-ring because the cross section is O-shaped. In the aspect of functions, the sealing performance is reliable, the wear-resisting rubber sealing ring is wear-resisting, has an automatic elastic compensation function, and has a wide application range in both working temperature and pressure; in the aspect of use, the water seal type engine oil seal is simple in design, small in structure, convenient to assemble and disassemble and low in cost, and therefore O-shaped sealing rings are mostly used at water seals and oil seals in the arrangement of the engine.
When the O-shaped sealing ring is designed, the diameter of the O-shaped sealing ring is usually smaller than the width of the mounting groove, so that the O-shaped sealing ring is convenient to mount, and the diameter of the O-shaped sealing ring is larger than the height of the mounting groove, so that the sealing mounting is ensured. However, in the actual installation process, the shape is complex, the O-ring is easy to fall off and difficult to observe in the process of attaching the part to the engine installation surface after being placed in the part installation groove, the sealing performance of the engine is affected, and when the O-ring has a complex shape, the installation of the O-ring needs time to find the installation position, and the production efficiency is affected.
SUMMERY OF THE UTILITY MODEL
The utility model provides an anti-drop's sealing washer through setting up the location body and the anti-drop body, has improved the stability in the O shape sealing washer use.
The technical scheme of the utility model is realized like this:
the utility model provides an anti-drop's sealing washer, its includes O shape sealing washer body, anti-drop body, O shape sealing washer installation part and the location body, the inboard at O shape sealing washer body is established to the anti-drop body, the anti-drop body is the circular convex block structure, the thickness of anti-drop body and O shape sealing washer body diameter with be greater than the width of mounting groove on the O shape sealing washer installation part, the highly diameter that is less than O shape sealing washer of O shape sealing washer installation part upper portion mounting groove, the cuboid lug that the location body was equipped with in for O shape sealing washer mounting plane.
The utility model discloses an among the anti-drop's sealing washer, the anti-drop body sets up along O shape sealing washer central curve equidistance, the anti-drop body forms for the preparation of same kind of material with O shape sealing washer, the anti-drop body is equipped with a plurality of.
Implement the utility model discloses an anti-drop's sealing washer has following beneficial effect:
1) the anti-falling body ensures that the O-shaped sealing ring is not easy to fall off in the installation process, is beneficial to improving the assembly quality and ensures sealing;
2) the positioning body is convenient for identifying the direction of the O-shaped sealing ring in the installation process, and the production efficiency is improved.
Drawings
Fig. 1 is a schematic view of the anti-falling sealing ring of the present invention.
In the figure: the anti-falling device comprises an anti-falling body 1, a positioning body 2 and an O-shaped sealing ring 3.
Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
As shown in fig. 1 the utility model discloses an anti-drop's sealing washer, it includes O shape sealing washer 3 body, anti-drop 1, O shape sealing washer installation part and location body 2, anti-drop 1 establishes the inboard at O shape sealing washer 3 body, anti-drop 1 is the circular convex block structure, anti-drop 1's thickness and O shape sealing washer 3 body diameter with be greater than the width of mounting groove on the O shape sealing washer 3 installation part, the highly be less than O shape sealing washer 3's diameter of O shape sealing washer 3 installation part upper portion mounting groove, location body 2 is the cuboid lug that is equipped with in the O shape sealing washer 3 mounting plane, anti-drop 1 sets up along O shape sealing washer 3 central curve equidistance, anti-drop 1 forms for the preparation of same kind of material with O shape sealing washer 3, anti-drop 1 is equipped with a plurality of.
The utility model discloses a theory of operation does: in the engine assembling process, the O-shaped sealing ring 3 is installed in the installation groove, wherein the positioning body 2 of the O-shaped sealing ring 3 is placed in the installation groove, the anti-falling body 1 of the O-shaped sealing ring 3 is extruded in the installation groove, and the O-shaped sealing ring 3 is fixed in the installation groove by the elasticity of the O-shaped sealing ring 3 to prevent falling. Thus, the object of the present invention can be achieved.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
