Abstract

(57) [Abstract] [Purpose] Fluid, especially internal fluid caused by looseness, etc. between the hose that allows liquid such as oil under pressure to pass through and other parts, or in the connection part between hoses. It relates to a protective structure that should prevent permeation. A flexible hollow cylindrical cover extending on both sides of the hose and a part connected to the hose or at a connecting part between the hoses is provided. Then, both ends of the cover are clamped to the hoses and parts with a clamp material.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention is intended to prevent the penetration of internal fluid due to loosening or the like between the hose and other parts through which a fluid, especially a liquid such as oil under pressure, passes, or the connection between the hoses. Regarding the structure.

[0002]

[Prior art]

 In particular, the hose used in the hydraulic system of automobiles has a sufficient safety factor so that the fluid inside does not penetrate due to the pressure load, but it is connected to the hose and this hose. At the joint between the parts or the hose, no particular consideration is given to insufficient tightening or loosening of the metal fittings constituting the joint.

As a result, when the internal fluid permeates from the connecting portion, the connecting portion may contaminate the engine of the vehicle and peripheral devices such as a muffler and an exhaust pipe.

[0004]

[Problems to be solved by the device]

 This invention intends to eliminate the inconvenient situation caused by the permeation of the internal fluid from the connecting portion, which has been conventionally experienced as described above.

[0005]

[Means for Solving the Problems]

 That is, according to this invention, a flexible hollow cylindrical cover extending to both sides of the hose and a part connected to the hose or at a connection part between the hoses is provided. A structure for protecting the connecting portion of the hose is proposed, in which the both ends of the cover are fastened to the hose or parts with a clamp material.

[0006]

[Action]

 In the above structure, if the connecting portion is loosened for some reason, the internal fluid that has permeated from the loosened portion is trapped in the hollow cylindrical cover whose both ends are tightened, It is prevented from bleeding.

[0007]

【Example】

 First, referring to FIG. 2, a conventional example will be described. 1 is a hose with a metal fitting, and the hose 1 with the metal fitting is a hose main body 2 and a metal fitting for connection (in the example shown, a nickel nut). 3), and this connecting metal fitting 3 is screwed and fixed to the connecting metal fitting 5 of the component 4 on the other side of the connection to form the connecting portion 6.

If loosening occurs between the connecting metal fittings 3 and 5 in the connecting portion 6 due to use over time, for example, due to vibration of the vehicle, the fluid inside the connecting portion 6 moves in the direction of the arrow. The situation of permeation occurs.

Here, the present invention aims to prevent the occurrence of such a situation by covering the above-mentioned connecting portion 6 with a cover 7 to prevent the permeation of the internal fluid. In FIG. 1 showing the structure of the present invention, the same or equivalent parts as shown in FIG. 2 are designated by the same reference numerals, and the description thereof will be omitted.

For the cover 7, a material having oil resistance, heat resistance, chemical resistance, etc. is selected and used according to the type of fluid passed through the hose 1. The cover 7 in the shape of a cover is extended on both sides of the connecting portion 6 and is covered, and both ends of the cover 7 are clamped to the hose 1 and the component 4 by a clamp member 8. . As the clamp material 8, a band or a push clamp is arbitrarily selected according to the pressure of the fluid passing through the inside of the hose.

In the illustrated example, the connecting portion 6 formed between the hose 1 and the component 4 is shown and described, but in practice, the application of the present invention to the connecting portion between the hoses is naturally considered. It

In the above configuration, when the internal fluid permeates from the connecting portion 6 for some reason, the permeated fluid is retained in the cover 7 and does not bleed to the outside.

In the illustrated example, the connecting portion formed by connecting the connecting metal fittings 3 and 5 has been described, but with regard to the application of the present invention, for example, the connecting portion of the type for directly implanting Etc., including all conceivable connecting parts.

[0014]

[Effect of device]

 By adopting the above-mentioned protective structure of this invention, when the internal fluid is accidentally permeated from the hose connecting portion, it is trapped in the cover and does not bleed to the outside, so that it is permeated. It is extremely effective and useful in that it can prevent the peripheral fluid from being contaminated by the internal fluid.
