JPH053786U - Protective device for hydraulic pipe cap - Google Patents

Abstract

(57) [Summary] [Purpose] When the hydraulic piping is removed from the hydraulic device, the outflow of hydraulic fluid and the inclusion of foreign matter are reliably prevented. [Structure] When the hydraulic piping is removed for maintenance and repair of the hydraulic device, apply a disc to the mouthpiece and clamp it with a plurality of clips with appropriate spring action.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hydraulic device, and more particularly, to a protective device for a base portion of a hydraulic pipe.

[0002]

[Prior art]

  Remove the hydraulic piping for maintenance, inspection, and repair of the hydraulic device, but leave it If it is left, the hydraulic fluid will flow out or dust will adhere. So generally corks , I put on rubber stoppers, stuck with adhesive tape, and covered with a waste cloth.   In FIG. 5, 51 is a hydraulic pipe, 51a is its mouthpiece, and 53 is a cork stopper or a rubber stopper. It is fitted inside the base portion 51a.   FIG. 6 shows a state in which the adhesive tape 54 is attached to the end surface of the base 51a. . In FIG. 7, the entire base 51a is covered with a waste cloth 55, and a string 56 is used. It is in a state of being.

[0003]

[Problems to be solved by the device]

  If cork stoppers or rubber stoppers are used for the base of the hydraulic piping, debris will be generated when attaching or detaching them. Foreign matter may be mixed in the hydraulic fluid. The mixed foreign matter may cause the failure of the hydraulic system. Could be. In addition, the O-ring may fall off.   When the adhesive tape is attached, it may come off or be removed if it is not attached properly. When it is removed, it may be torn and it may take an unexpected amount of time.   If it is covered with a waste cloth, lint may get mixed in with the hydraulic fluid or the hydraulic fluid may stain. Take it out and pollute the surroundings   The present invention seeks to provide a protection device for hydraulic piping which does not have the above-mentioned drawbacks. Is.

[0004]

[Means for Solving the Problems]

  In order to solve the above problems, the outer diameter of the base of the hydraulic pipe is almost equal to or slightly larger than A disk made of metal or resin that can chemically withstand the working fluid and this disk Consists of a clip that comes into close contact with the pipe base.

[0005]

【Example】

  1 is a sectional view showing an embodiment of the present invention, and FIG. 2 is a view of FIG. 1 viewed in the direction of arrow A. is there. In FIG. 1, 1 is a hydraulic pipe, 1a is its mouthpiece, and 2 is an O-ring for sealing. 3 is a disc, and 4 is a clip. Hydraulic pressure for maintenance, inspection and repair of hydraulic equipment When the pipe is removed, place the disc 3 on the end face of the mouthpiece 1a as shown in the figure, and By clamping the circumference of the clip with a plurality of clips 4 with appropriate spring action The hydraulic fluid in the hydraulic pipe 1 does not leak due to the O-ring sealing function, and It is also possible to prevent foreign matter from entering.

[0006]   FIG. 3 shows a structure in which the above-mentioned clip is attached to a disc using a hinge.   FIG. 4 is a view of FIG. 3 viewed in the direction of arrow B. 6 is a hinge pin, and a clip 4a And the mounting plate 5 are pivotally attached. By doing this, the clip and the disc It is easier to handle than it is loose.

[0007]

[Effect of device]

  As described above, according to the present invention, the structure is simple, but the outflow and operation of hydraulic fluid It is possible to reliably prevent foreign matter from entering the liquid, and its practical value is extremely high.
