Description

BACKGROUND OF THE INVENTION

1. Technical field of the invention

This invention relates to a stopper for oil lines, and more particularly to one that can be used to shut off two different types of oil lines to reduce the cost of purchasing tools and to provide more convenience to the user when taking them with them.

2. Description of the Related Art

When a car is to be repaired, in general, different types of oil lines of the car must be separated from the car to facilitate the maintenance and repair work. After the oil lines have been removed, the openings of the pipes must be shut off to prevent oil oil from leaking out. There are two types of oil lines: the one-port type oil passage and the two-port type oil passage. A conventional method used to shut off the single port type oil line is noted 1 the insertion of a clamp body 1 which consists of an upper clamping plate 10 and a lower clamping plate 11 is composed, which face each other, wherein the upper clamping plate 10 and the lower clamping plate 11 via a pivot axis 12 pivotally connected to each other, wherein a torsion spring 13 between the upper clamping plate 10 and the lower clamping plate 11 is provided, wherein the two ends of the torsion spring 13 each against the inner side of the upper clamping plate 10 and the lower clamping plate 11 Apply pressure, with a stop element 100 on the other side of the inner side of the upper clamping plate 10 and an engagement groove 110 on the other side of the lower clamping plate 11 is arranged, whereby the clamping body 1 can be clamped to an oil line A, so that the stop element 100 the upper clamping plate 10 of the clamp body 1 the pipe opening A1 of the oil line A shuts off, the oil line A firmly into the engagement groove 110 the lower clamping plate 11 can be engaged and through the upper clamping plate 10 and the lower clamping plate 11 firmly clamped and held, whereby the pipe opening A1 of the oil line A can be shut off, so that the oil in the oil line A does not leak. A conventional method used to stop the double-opening-type oil passage B will be described with reference to FIG 2 , with the help of another clamp body 2 achieved, which consists of an upper clamping plate 20 and a lower clamping plate 21 is composed, which face each other, wherein the upper clamping plate 20 and the lower clamping plate 21 via a pivot axis 22 pivotally connected to each other, wherein a torsion spring 23 between the upper clamping plate 20 and the lower clamping plate 21 is provided, wherein the two ends of the torsion spring 23 each against the inner side of the upper clamping plate 20 and the lower clamping plate 21 Apply tension, with two opposing stop elements 200 . 210 on the upper clamping plate 20 and on the other side of the inner side of the lower clamping plate 21 are arranged, whereby the clamping body 2 can be clamped to an oil line B, so that the stop element 200 the upper clamping plate 20 of the clamp body 2 and the stop element 210 the lower clamping plate 21 of the clamp body 2 each shut off the two pipe openings B1 of the oil line B, bringing the oil line B through the upper clamping plate 20 and the lower clamping plate 21 firmly clamped and held, so that the two pipe openings B1 of the oil line B can be shut off, whereby the oil in the oil line B does not leak.

However, when a car is being repaired, the conventional methods described above for the two different types of oil lines A and B require two different clamping tools to be prepared for use at all times. Therefore, the entrainment is tedious and uncomfortable and leads to higher costs when purchasing the clamping tools are caused.

From the DE 20 2012 103 925 U1 is a blocking device for locking of oil lines of different dimensions known that consists mainly of a left and a right clamping element and an elastic element. The left and right clamping element is provided in front each with a clamping portion and the rear each with a handle. The clamping portion of the left-side female clamping element is provided with a bolt, while the clamping portion of the right-hand element is provided with a through-hole in the front. A recess on the inside of the right clamping member is formed behind the through hole, wherein a hollow pin is arranged convexly on the recess and wherein a Lagebegrenzungsnut is provided on the surface of the hollow pin. The hollow pin is guided through the through holes of a positioning element, a plate, a spring and an intermediate layer. The positioning element has several positioning ribs. The plate is accordingly provided at the bottom with a plurality of positioning slots, in which engage the positioning ribs.

Furthermore, from the DE 35 32 609 A1 a device for sealing pipes and openings is provided, in which a gripping device comprises a pipe socket and one in the device attached clamping device presses a sealing rubber on the opening to be closed.
