Abstract
The utility model 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 utility model 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 the sealing of this screw thread realization and oil pipe.But due to the deformability of rubber, after long-term use, the internal surface of rubber can relax gradually, cause the sealing of oil sealing and oil pipe to decline.
Model utility content
The purpose of this utility model is to propose a kind of sealing can keep for a long time good oil sealing.
The internal surface of oil sealing body of the present utility model is provided with screw thread, and key is to be located in described body the elastic skeleton that pressure is provided to body internal surface.After installing, this elastic skeleton can continue to provide pressure to body internal surface, thereby the internal surface of body is fitted tightly with oil pipe all the time, thereby ensures that sealing is good.
Specifically, elastic skeleton is that the closure being made up of wavy steel wire is enclosed, this steel traveler has elasticity, can expand outwardly when mounted, to facilitate installation, and after installation finishes, can under self elastic force effect, inwardly shrink, thereby continuing provides pressure to body internal surface, improve sealing reliability.
Oil seal structure of the present utility model is simple, can adopt rubber and steel wire to vulcanize and be made into integration, easy for installation, and the reliability of sealing is high, long service life.
Brief description of the drawings
Fig. 1 is the structural drawing of elastic skeleton of the present utility model.
Fig. 2 is the structure principle chart of oil sealing of the present utility model.
Embodiment
Contrast accompanying drawing below, by the description to embodiment, embodiment of the present utility model is described in further detail as effect and the working principle etc. of the mutual alignment between the shape of related each member, structure, each several part and annexation, each several part.
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 in described body 1 elastic skeleton 3 that pressure is provided to body 1 internal surface.Specifically, elastic skeleton 3 is that the closure being made up of wavy steel wire is enclosed, this steel traveler has elasticity, can expand outwardly when mounted, to facilitate installation, and after installation finishes, can under self elastic force effect, inwardly shrink, thereby continuing provides pressure to body 1 internal surface, thereby the internal surface of body 1 is fitted tightly all the time with oil pipe, improve sealing reliability.
Oil seal structure of the present utility model is simple, can adopt rubber and steel wire to vulcanize and be made into integration, easy for installation, and the reliability of sealing 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 in described body the elastic skeleton that pressure is provided to body internal surface.
2. oil sealing according to claim 1, is characterized in that described elastic skeleton is that the closure being made up of wavy steel wire is enclosed.
