Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to an improvement in an end member having a guide pipe engaged with the end of a control cable conduit. More particularly, the present invention relates to an end member having a telescoping guide pipe engaged with the end of a conduit.

[Prior art]

Conventionally, control cables (hereinafter simply referred to as cables) that use this type of terminal member are the third type.
As shown in the figure, a cap member 12 made of metal or the like is fixed to the end of a flexible conduit 11, a substantially spherical concave surface 12a is provided at one end of the cap member, and a guide pipe 13 made of metal is provided. has a substantially spherical convex surface 13a at one end, and the concave surface 1
A ball and socket joint 16 in which a convex surface 13a is rotatably fitted into 2a.
A flexible inner cable 14 is rotatably engaged with the cap member 12 and slidably inserted into the conduit 11, and the end of the inner cable is slidably inserted into the guide pipe 13. The moving rod 5 is tightened.

In such a configuration, the rod 15 is slid in the A or B direction to remotely control the driven equipment, but the sliding stroke of the cable determines the length of the guide pipe 13 that holds the rod 15. . However, the stroke of the cable is not constant depending on the operating device or the driven device, and it is inconvenient that guide pipes of various lengths must be prepared in order to satisfy each condition. In addition, as shown in Figure 3, in the case of a cable with an extremely long stroke, the guide pipe must necessarily be long to cover the stroke. There is a disadvantage that the distance T from the mounting groove 17 to the midpoint P position between the longest stroke L and the shortest stroke I of the rod 15 is long, which requires a large space.

[Purpose of invention]

In view of the above-mentioned drawbacks, the object of the present invention is to provide an end member for a cable conduit equipped with a guide pipe that can sufficiently hold a rod even for a cable with a long stroke and that can be installed in a relatively narrow space. It's about doing.

[Structure of the idea]

The present invention relates to an end member for a cable conduit, which is provided with a guide pipe that freely expands and contracts according to the sliding stroke of the cable.

[Embodiment of the idea]

An embodiment of the terminal member of the present invention will be described based on the drawings, but the present invention is not limited to this embodiment.

FIG. 1 shows a cap member 2 fixed to the end of a conduit 1, and a fixed cylinder 3 having a sphere 3a at one end and a stopper 3b having a small diameter on the inner circumferential surface of a region at the other end.
is rotatably engaged, is slidably fitted into the inner circumferential surface 3c of the fixed cylinder, and has the stopper 3 at one end.
A sliding tube 4 having a collar 4a that comes into contact with b is assembled.

On the other hand, one end of the fixed cylinder 3 is in contact with a washer 6 fixed near the sphere 3a, and the other end is in contact with a collar 4 provided on the sliding cylinder 3, so that the sliding cylinder 4 is connected to the stopper 3b. It is biased in the B direction as if pressing.

FIG. 2 is a diagram showing the operating state of the terminal member of the present invention. When the rod 9 is slid in the direction A in FIG. 1, the end of the rod will eventually come into contact with the end of the sliding tube 4, When the rod is slid in the A direction, the sliding tube 4 is housed together with the rod 9 in the A direction, that is, inside the inner circumferential surface 3c of the fixed tube 3, and the coil spring 5
is compressed, the guide pipe 7 becomes shorter, and the second
The state will be as shown in the figure.

Next, when the rod 9 is returned to the direction B, the sliding tube 4 also slides in the direction B together with the rod 9 due to the repulsive force of the coil spring 5. When the collar 4a contacts the stopper 3b, only the rod 9 remains. It is possible to slide the rod 9 by a predetermined stroke by sliding in direction B.

[Effect of idea]

By using a telescopic guide pipe, the end member of the conduit of the present invention eliminates the need to prepare a wide variety of guide pipes to match the stroke of each cable as in the past, and only the minimum number of types of guide pipes are required. By preparing the pipe, it can be used for cables with far more types of strokes than conventional guide pipes, and the setting position can be made smaller compared to conventional guide pipes, so it can be installed in a relatively narrow space. This is an idea that has unprecedented economic effects.
