Abstract
The invention provides an oil seal capable of enabling sealability to keep good in a long time. A thread is formed on the inner surface of an oil seal body, and the oil seal is characterized in that an elastic framework for providing pressure for the inner surface of the oil seal body is arranged in the oil seal body. After mounting is completed, the elastic framework can provide pressure for the inner surface of the oil seal body continuously to enable the inner surface of the oil seal body to be in tight fit with an oil tube constantly, so that good sealability is guaranteed. The oil seal is simple in structure, capable of being integrally made of rubber and steel wires by means of vulcanization, convenient to mount, extremely high in sealing reliability and long in service life.
Description
Technical field
The present invention relates to a kind of oil sealing.
Background technique
Traditional oils envelope is generally rubber and makes, and internal surface is provided with screw thread, utilizes this screw thread to realize the sealing with oil pipe.But due to the deformability of rubber, after prolonged, the internal surface of rubber can relax gradually, the sealing of oil sealing and oil pipe is caused to decline.
Summary of the invention
The object of the invention is to propose a kind of sealing and can keep good oil sealing for a long time.
The internal surface of oil sealing body of the present invention is provided with screw thread, and key is to be located at the elastic skeleton providing pressure to body internal surface in described body.After installing, this elastic skeleton can continue to provide pressure to body internal surface, thus the internal surface of body is fitted tightly with oil pipe all the time, thus ensures that sealing is good.
Specifically, elastic skeleton is the closed circle be made up of wavy steel wire, this steel traveler has elasticity, can expand outwardly when mounted, to facilitate installation, and after installation terminates, inwardly can shrink under its own resilient effect, thus continue to provide pressure to body internal surface, improve sealing reliability.
Oil seal structure of the present invention is simple, can adopt rubber and steel wire sulfuration and be made into integration, easy for installation, and the reliability sealed is high, long service life.
Accompanying drawing explanation
Fig. 1 is the structural drawing of elastic skeleton of the present invention.
Fig. 2 is the structure principle chart of oil sealing of the present invention.
Embodiment
Contrast accompanying drawing below, by the description to embodiment, the effect and working principle etc. of the specific embodiment of the present invention as the mutual alignment between the shape of involved each component, structure, each several part and annexation, each several part are described in further detail.
Embodiment 1:
As shown in the figure, the oil sealing of the present embodiment comprises body 1, and the internal surface of body 1 is provided with screw thread 2, and key is to be located at the elastic skeleton 3 providing pressure to body 1 internal surface in described body 1.Specifically, elastic skeleton 3 is the closed circle be made up of wavy steel wire, this steel traveler has elasticity, can expand outwardly when mounted, to facilitate installation, and after installation terminates, inwardly can shrink under its own resilient effect, thus continue to provide pressure to body 1 internal surface, thus the internal surface of body 1 is fitted tightly with oil pipe all the time, improve sealing reliability.
Oil seal structure of the present invention is simple, can adopt rubber and steel wire sulfuration and be made into integration, easy for installation, and the reliability sealed is high, long service life.
Claims (2)
1. an oil sealing, the internal surface of body is provided with screw thread, it is characterized in that being located at the elastic skeleton providing pressure to body internal surface in described body.
