Description

Length control device of telescopic extension tube {A LENGTH CONTROL DEVICE FOR TELESCOPIC EXTENSION PIPE}

The present invention relates to a length adjusting device of the telescopic extension tube.

In general, the pipe is used as a support (leg) for supporting the structure (desks, tables, advertisements), or may be used as a suction pipe to a vacuum cleaner that sucks dust or garbage. Such a pipe may need to be adjusted in length when used in a structure or a cleaner.

Therefore, the pipe described above is assembled as follows by a general length adjusting device as shown in Figures 1 and 2 to adjust the length.

First, the inner extension tube 60 is inserted into the outer extension tube 50 as shown in Figs. Subsequently, the hook 30 is rotatably fixed to the end of the outer extension pipe 50 as the shaft 30a is inserted into the fixing groove 50a together with the spring 40. Subsequently, the cover 20 extends as the screw 10 is fastened to the fastening groove 50b through the fastening hole 20a while the fastening jaw 20b is fastened to the fastening jaw fixing groove 50c. It is fixed at the end of. Thus, the length adjusting device is completed assembly.

As such, the length adjustment device is assembled as the hook 30 is caught in the slit (60a) inclined to one side of the inner extension tube 60, as shown in Figure 2 (a), the inner extension tube 60 By pulling to one side, the protruding length of the inner extension tube 60 from the outer extension tube 50 can be adjusted. That is, the hook 30 is sliding on the inclined surface of the slit 60a when the inner extension tube 60 is pulled to one side, so the inner extension tube 60 may be moved to one side.

In addition, the length adjustment device, as shown in (b) of Figure 2 when pressing the other end of the hook 30, one end of the hook 30 is rotated relative to the axis 30a of the hook 30, the slit ( Deviation from 60a). In this state, the user moves the inner extension tube 60 to the inner side of the outer extension tube 50 to adjust the length, and when one of the hooks 30 is released when the hook 30 is released from the shaft of the hook 30. Since the reverse rotation based on (30a) is inserted into another slit (60a) again, the length-adjusted inner extension tube 60 may be fixed in the outer extension tube (50).

However, the above-described length adjusting device, as shown in (a) of FIG. 2, as the slit 60a formed in the inner extension tube 60 is inclined to one side, the outer extension tube 50 from the outer extension tube 50 by external pressure When the 60 is drawn out, there is a problem in that the hook 30 is not securely fixed to the inner extension pipe 60 while sliding in the slit 60a.

On the contrary, when an external pressure is applied to the inner extension pipe 60 so that the inner extension pipe 60 is pushed into the outer extension pipe 50 and inserted, the portion opposite to the inclined surface of the slit 60a pushes the end of the hook 30. Therefore, the end of the hook 30 is bent by the length of the hook 30, there is also a problem that the end of the hook 30 is separated from the locking jaw (60a).

Moreover, since the cover 20 does not keep the hook 30 caught in the latching jaw 60a, the end of the hook 30 is not structurally held in the hooking jaw 60a. There is also a problem.

The present invention has been made to solve the above problems, it is possible to provide a length adjustment device for the telescopic extension tube that can be fixed firmly while the fixed state can be fixed to the inner pipe of the length is adjusted in the outer pipe. That is the purpose.
