Abstract

The utility model relates to a seal ring, in particular to an O-shaped rubber seal ring for a positioning structure. Both the inner ring and the outer ring of the O-shaped ring are provided with uniformly-distributed and protruded outer convex hulls and inner convex hulls. The inner diameter of the O-shaped rubber seal ring is h; the total width of the outer convex hull and the inner convex hull is a; the height is the diameter d of the O-shaped rubber seal ring; the radius of the inner convex hull is c; the radius of the outer convex hull is b; the cross section radius of the inner convex hull is g; the cross section radius of the outer convex hull is e; and the connecting radius of the convex hull and the O-shaped rubber seal ring is f. The O-shaped rubber seal ring for the positioning structure has the advantages of simple structure, low cost and convenience for installation, operation and use; the outer convex hull can be stably blocked in mounting and positioning grooves along different directions so as to prevent the installation of the O-shaped rubber seal ring products from dropping caused by tilting or upending the positioning groove; moreover, the outer convex hull structures are all misplaced on the upper and the lower positions of a ring body; in the O-shaped rubber seal ring, as fewer positioning convex hulls are additionally arranged on the inner diameter and the outer diameter of products, a mould is simple to manufacture, and the product weight increment is little; therefore, the manufacturing cost of the O-shaped rubber seal ring product with a novel structure is not greatly increased and is not changed fundamentally.

Description

Position structure O type rubber seal

Technical field: the utility model relates to seal ring, is specially a kind of position structure O type rubber seal.

Background technique:, all require very strict to the installation efficiency of each Related product along with the raising of the efficient of car engine machine production line.The effect of the O RunddichtringO sealing under the axial seal condition is bad now, often produces quality problems, has the thing that gets loose to take place, and does not guarantee the normal operation of motor car engine.

Summary of the invention: the purpose of this utility model is to provide that a kind of simple in structure, with low cost, fitting operation is convenient, the gastight position structure O type rubber seal of sealing.The purpose of this utility model is achieved in that it comprises O type rubber seal, outer convex closure, interior convex closure.Internal and external cycle at O type circle is provided with the outstanding outer convex closure of even distribution, interior convex closure.The internal diameter h of O type rubber seal, the overall width of outer convex closure, interior convex closure are a, highly are the diameter d of O type rubber seal, interior convex closure radius is c, and the radius of outer convex closure is b, and interior convex closure section radius is g, outer convex closure section radius is e, and convex closure is connected radius f with O type circle; The internal diameter of O type rubber seal is that h is φ 10-φ 100, overall width is that a is 3-10mm, highly the diameter d for O type rubber seal is 2-8mm, interior convex closure radius is that c is 1-10mm, the radius of outer convex closure is that b is 1-10mm, interior convex closure section radius is that g is 1-5mm, and outer convex closure section radius is that e is 1-5mm, and it is 1-8mm that convex closure is connected radius f with O type rubber seal.The utility model has the advantages that: simple in structure, with low cost, easy for operation by adorning; In the installing and locating groove that is stuck in different direction that outer convex closure can be firm, prevent since locating slot tilt or put upside down due to O type rubber seal product install and come off, in addition, outer convex closure structure is all wrong from above the annulus circle body and lower position; Because this O RunddichtringO has only increased a spot of location convex closure at the interior external diameter of product, Mould Machining is simple, the product weight increase seldom, so the fabricating cost of new structure O RunddichtringO product do not have too big increase, and is constant substantially.

Description of drawings: Fig. 1 is the utility model structural principle schematic representation.Fig. 2 is the utility model structural principle generalized section.

Embodiment: it comprises O type rubber seal 1, outer convex closure 2, interior convex closure 3.The internal diameter h of O type rubber seal 1, the overall width of outer convex closure 2, interior convex closure 3 is a, highly is the diameter d of O type rubber seal 1, interior convex closure 3 radiuses are c, and the radius of outer convex closure 2 is b, and interior convex closure 3 section radius are g, outer convex closure 2 section radius are e, and convex closure is connected radius f with O type circle; The internal diameter of O type rubber seal 1 is that h is φ 10-φ 100, overall width is that a is 3-10mm, highly the diameter d for O type rubber seal 1 is 2-8mm, interior convex closure 3 radiuses are that c is 1-10mm, the radius of outer convex closure 2 is that b is 1-10mm, interior convex closure 3 section radius are that g is 1-5mm, and outer convex closure 2 section radius are that e is 1-5mm, and it is 1-8mm that convex closure is connected radius f with O type rubber seal 1.The utility model working procedure is: O type rubber seal is put into the mounting groove that needs sealing, the equally distributed inside and outside convex closure place of O type rubber seal product can be subjected to mounting groove extruding force radially, groove has certain constraint effect to O type rubber seal, makes O type rubber seal product being fixed in the mounting groove tightly.In this process, have only firm being stuck in the mounting groove of O type rubber seal product, could satisfy the installation efficiency of whole production line, thereby satisfy the product usage requirement.
