Figure 3 is a cross-sectional view showing a length control lever mounting structure of the handy-stick vacuum cleaner according to the present invention, Figure 4 is an exploded perspective view showing the configuration of the length control lever of the handy-stick vacuum cleaner according to the present invention 1 and 2, the same components as those of the conventional structures shown by the same reference numerals, but a detailed description thereof will be omitted.

First, Figure 3 is a cross-sectional view showing the mounting structure of the length adjustment lever of the handy-stick vacuum cleaner according to the present invention. As shown, the adjustment lever 40 to adjust the length of the handle according to the body shape of the operator is disposed in an approximately L shape, by the pin 48 to the guider 50 having a cylindrical portion (50a) It has a configuration that is rotatably mounted.

Here, the guider 50 having the cylindrical portion 50a into which the handle 24 is inserted is formed with a guide portion (50b in FIG. 4) for guiding the longitudinal movement of the pipe 26, so that the operator himself When pulling out the handle 24 to fit the body shape of the, the pipe 26 is to be supported so that it can move smoothly along the longitudinal direction.

The presser part 40a which the operator presses by hand is formed in the lower end of the control lever 40 which is rotatably mounted to the above-mentioned guider 50 by the pin 48 and restrains the movement of the pipe 26. The upper end of one side is attached with a stopper 42 selectively inserted into a plurality of engaging grooves (26a, 26b) formed in the pipe (26).

Further, a protrusion 44 into which the pressure spring 46 is fitted is formed on the rear surface of the adjustment lever 40 with the stopper 42 attached thereto. One end of the pressure spring 46 is supported by the projection of the control lever 40, the other end is elastically supported by the main body 12. Therefore, the stopper 32 attached to the control lever 40 is always pressed toward the pipe 26 by the pressure spring 46, thereby maintaining the engagement state with the engaging grooves 26a and 26b.

The control lever 40 having such a configuration serves to selectively restrain the longitudinal movement of the pipe 26 inserted into the guide hole 22 of the main body 12. For example, in order to increase the length of the handle 24 to fit the key of the operator, the pressing lever 40a constituting the lower end of the control lever 40 in the direction of the arrow (P '), the adjustment lever 40 is a pin Rotate around (48). Accordingly, the stopper 42 attached to one upper end of the control lever 40 moves in the direction of the arrow Q 'and is separated from the locking grooves 26a and 26b to release the restrained state of the pipe 26. .

At this time, since the pipe 26 is slidable along the inner wall of the guide hole 22, the worker pulls up the handle 24 and pulls out the pipe 26 until it becomes a length suitable for his body shape. Just do it. In this process, since the control lever 40 is always maintained in a pressurized state by the pressure spring 46, the stopper 42 attached to the control lever 40 is another locking groove (26a) formed in the pipe 26, By inserting into 26b, the movement of the pipe 26 is restrained. In this way, the stopper 42 is inserted into the engaging grooves 26a and 26b formed in the pipe 26 to restrain its longitudinal movement, so that the handle is held in the fixed state in the guide hole 22.

If the suction end (14 of FIG. 1) of the main body 12 collides with an obstacle and the operator presses the handle 24 while using the handy-stick vacuum cleaner of the present invention, The fixed state is held firmly.

That is, when the handle 24 is pressed downward while the pressing portion 40a of the adjusting lever 40 is not pressed, the adjusting lever 40 is rotated about the pin 48 as opposed to the direction of the arrow P '. Since the stopper 42 also rotates in the opposite direction to the arrow Q 'direction and is further pressed in the locking grooves 26a and 26b, the pipe 26 is prevented from being pressed into the guide hole 22. .

After the cleaning is completed, when the handle 24 is stored in the guide hole 22 of the main body 12, as described above, the adjustment lever 40 is pressed in the direction of the arrow P 'to press the stopper 42. After separating from the locking grooves 26a and 26b, the handle 24 may be pressed downward. At this time, the pipe 26 is supported by the guider 50 so as to slide smoothly along the inner wall of the guide hole 22 formed in the main body 12, which will be described later in FIG.

Next, as shown in FIG. 4, the guider 50 having the cylindrical portion 50a in which the handle 24 is accommodated is formed with a guide portion 50b for supporting the longitudinal direction of the pipe 26. The mounting hole 52 for mounting the control lever 40 is formed. Moreover, the flange 54 which has the fastening hole 54a for attaching the guider 50 to the main body 12 is attached. Accordingly, the guider 50 is fixed to the main body 12 by a conventional bolt or fastening screw (not shown) via the flange 54, while the adjusting lever 40 restrains the longitudinal movement of the pipe 26. Has a structure that is rotatably mounted to the guider 50 by the pin 48.

The guide portion 50b of the guider 50, which is disposed substantially perpendicular to the cylindrical portion 50a, guides the pipe 26 to move smoothly along its longitudinal direction when adjusting the length of the handle 24. On the other hand, after the stopper 42 is inserted into the locking grooves 26a and 26b of the pipe 26, the pipe 26 is firmly supported to thereby secure the pipe 26 by an external impact applied through the handle 24. ) To prevent flow.

Therefore, even when the wheel 16 of the main body 12 is caught by an obstacle in front of the cleaner in use and a force is applied to the handle 24, the stopper 42 is caught by the pressing spring 46. ) And (26b), the pipe 26 is prevented from entering the guide hole 22, while the pipe 26 is firmly supported by the guide portion 50b formed in the guider 50, The handle 24 can be prevented from being inserted into the guide hole 22.

As described above, the length adjustment lever mounting structure of the handy-type vacuum cleaner according to the present invention prevents the handle from entering the guide hole of the main body by a front obstacle, thereby improving work efficiency and damaging by sudden pressurization of the handle. It has the effect of preventing it in advance.
