Description

OIL PIPE STOPPER

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to an oil pipe stopper, particularly to one that can be employed for stopping two different-type oil pipes, able to lower the expense of purchasing tools and convenient to be carried and used.

2. Description of the Prior Art

Generally, when a car is to be repaired, various kinds of oil pipes of the car have to bc detached from the car for facilitating maintenance and after the oil pipes are disassembled, the orifices of the oil pipes must be clogged to prevent oil in the oil pipes from leaking out. There arc Iwo types of oil pipes: a single orifice-type oil pipe and a double orifice-type oil pipe.

A conventional way of stopping a single orifice oil pipe, referring to Fig. 1, is to employ an oil pipe clamp 1 that is composed of an upper clamping plate 10 and a lower clamping plate 11 facing each other. The upper clamping plate 10 and the lower clamping plate 11 are pivotally combined together by a pivot 12, and a torsional spring 13 is provided between the upper clamping plate 10 and the lower clamping plate 11, having two ends respectively resisting against an inner side of one end of the upper and the lower clamping plate 10 and 11. The upper clamping plate 10 has an inner side of another end fixed thereon with a stopping member 100, and the lower clamping plate 11 has another end disposed with an engage groove by which the clamping member 1 can be clamped on an oil pipe A. Thus, the stopping member 100 on the upper clamping plate 10 of the oil pipe clamp 1 can clog the pipe orifice Al of the oil pipe A, while the oil pipe A can be firmly engaged in the engage groove 110 of the lower clamping plate 11. By so designing, the oil pipc A can be firmly clamped and held by both S the upper clamping plate 10 and the lower clamping plate 11, and the pipe orifice Al of thc oil pipe A can be clogged to stop the oil in the oil pipe A from leaking out. A conventional way used for stopping a double orifice-type oil pipe B, referring to Fig. 2, is by means of another oil pipe clamp 2 composed of an upper clamping plate 20 and a lower clamping plate 21 facing each other and pivotally combined together by a pivot 22. A torsional spring 23 is assembled between the upper and the lower clamping plate 20 and 21 and has two ends respectively resisting against an inner side of one end of the upper clamping plate 20 and the lower clamping plate 21. The uppcr clamping plate 20 and the lower clamping p!atc 21 respectively have an inner side of another end fixed thereon with a stopping member 200, 210. Thus, the oil pipe B can be clamped and held by the oil pipe clamp 2, and the pipe orifices BI at two sides of the oil pipe B can respectively be clogged by the stopping member 200 and 210 on the upper clamping plate 20 and the lower clamping plate 21 for preventing the oil in the oil pipe B from leaking out.

However, according to the conventional ways mentioned above, when a car is repaired, two different clamping tools must be prepared for use anytime for matching with two different-typed oil pipes A and B, troublesome and inconvenient in carrying and increasing expense in purchasing clamping tools.
