Abstract

The utility model relates to a compound O-shaped sealing circle, which pertains to a sealing component in the mechanical technique field. The main technique character is that: the inside circumference of the square-shaped frame gasket with high intensity is fixedly provided with high elastic rubber sealing material. The utility model is of a simple structure, low manufacturing cost, light weight and long service life. The square-shaped frame gasket with high intensity adopts the high intensity material, and the utility model is of time saving and force saving when in processing or pressing cutting. The circumference is provided with an O-shaped high elastic rubber sealing material, which can make the sealing circle not only have sealing effect but also have limiting function. The utility model is used in the technical field of machine manufacturing with very ideal sealing effect.

Description

A kind of compound " O " type rubber seal

One, technical field

The utility model relates to a kind of seal ring, and specifically a kind of compound " O " type rubber seal belongs to mechanically a kind of air locking.

Two, background technique

In the mechanical assembly technique field,, usually between mechanical fitting and mechanical fitting, accompany different seal ring in order to make mechanical internal cavity sealing effect better.For example when industrial sewing machine and motor assembling, all need to seal butt joint, prevent that the joint poor sealing from causing gas leak of the oil leakage with gasket seal.Existing gasket seal adopts homogenous material mostly, as rubber seal, and easy deformation after this sealing material in use is squeezed.Be the accessory on plane when sealing particularly, make the seal ring deformed damaged and come off with existing air locking is the easiest, thereby cause between the mechanical fitting poorly sealed for interface.For this reason, mechanical fitting one end that people seal needs is provided with a circle groove, then seal ring is embedded in the groove of metalwork and docks then, can reach the seal action to metal device.Though this method can play the effect of sealing, process cutting to sealed metal device, like this with regard to invisible increase the manufacture cost of machinery.

Three, model utility content

The purpose of this utility model is in order to solve the above-mentioned defective that existing seal ring exists, and is that the mechanical fitting of sealing is not done any processing, just can reach the higher quality seal effect, thereby propose a kind of new technological scheme.

The technological scheme that the designing technique defective of its above-mentioned existence of solving the utility model is adopted is:

A kind of compound " O " RunddichtringO, it is to be made of square type high strength skeleton packing ring, be fixed with " O " type high elastic rubber sealing material on square type high strength skeleton packing ring circumference, it is circular that shape is opened in its cross section of described " O " type high elastic rubber sealing material.

On square type high strength skeleton packing ring inner circumference, be fixed with " O " type high elastic rubber sealing material.

The advantage that the utility model had is: simple in structure, cheap for manufacturing cost, in light weight, and long service life.Because " O " RunddichtringO has adopted the high elastic rubber sealing material, laborsaving saving time when processing or die cut, on its outer ring, be fixed with square type high strength skeleton gasket materials, can make this composite sealing ring both have excellent sealing effect, has spacing function again, can increase the mechanical compressive strength of seal ring greatly, use in machinery manufacturing technology field, the long-term seal effect is very desirable.

Four, description of drawings

Accompanying drawing 1 is a kind of example structure schematic representation of the utility model;

Accompanying drawing 2 is elevational schematic view of the utility model accompanying drawing 1.

Five, embodiment

Now with specific embodiment the utility model is described in further details in conjunction with the accompanying drawings:

A kind of compound " O " RunddichtringO, it is to do a square type high strength skeleton packing ring (1) by metallic material or high strength nonmetallic material, this square type high strength skeleton packing ring (1) is a cirque structure, sectional shape is a rectangle, reaches up and down at square type high strength skeleton packing ring (1) inner headed face and is fixed with " O " high elastic rubber sealing material (2) on the edge surface.

Claims

1, a kind of compound " O " RunddichtringO, it is to be made of square type high strength skeleton packing ring (1), it is characterized in that: be fixed with " O " type high elastic rubber sealing material (2) on square type high strength skeleton packing ring (1) circumference, it is circular that shape is opened in its cross section of described " O " type high elastic rubber sealing material (2).
