Description
BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a pipe connecting device for a vacuum cleaner, and more particularly, to a pipe connecting device for a vacuum cleaner that can be adjusted in length by a simple operation of a push button.
A vacuum cleaner is a type of vacuum cleaner widely used in homes and businesses, and absorbs dirt and trash away from the surrounding area by strong suction force using air pressure. The structure is composed of an intake port, a motor, a rotating blade, a filter, a dust-collecting case, an exhaust port, and the like. The commutator motor rotates the rotating blades more than 10,000 times to make the inside vacuum, and sucks dust or debris through the intake port. The dirt, debris, etc. that are sucked are filtered from the filter, and the air escapes to the exhaust port.
When the vacuum cleaner is used, the suction port is brought into contact with the floor, and the user holds the handle in a line state to push the vacuum cleaner. At this time, the length of the pipe connecting the suction port and the handle, Respectively.
Korean Patent Laid-Open Publication No. 10-1999-005687 entitled " Length Adjustable Extension Tub of Vacuum Cleaner " (published on Jan. 25, 1999) discloses such a conventional pipe length adjusting device.
This conventional technique is characterized in that a hollow outer tube having a fixing portion for fixing the suction brush to the front end portion and having a fixing groove formed at the rear end portion and a fixing projection engaging with the fixing groove are formed on the inner surface, A hollow inner pipe which is inserted into an inner circumferential surface of the fixing pipe and forms a fitting groove at a front end portion and has a fixing portion to which the knob is mounted at a rear end portion; And a sealing tube inserted into the outer tube is inserted into the outer tube so that the sealing tube is continuously assembled to provide a length adjustable extension tube of the vacuum cleaner.
However, this conventional technique has a problem that the operation is not fast because the inner tube is rotated in one direction to freely extend or reduce the entire assembly length.
SUMMARY OF THE INVENTION It is an object of the present invention to provide a pipe coupling device for a vacuum cleaner which can adjust the length of a pipe only by a simple pressing operation.
The present invention relates to a pipe having a first pipe formed with an engaging portion, a second pipe insertable into the inner periphery of the first pipe and having a plurality of fixing grooves arranged in the longitudinal direction, A guide holder having a stopper protruding downwardly so as to be inserted into the stopper, the guide spring including a push spring formed in a vertical direction and a guide spring formed in a horizontal direction, And a push button which is provided with a slide member which presses the stopper downward and which is biased elastically upwardly by the push spring and which releases the slide member from the upper end of the stopper when pressed, Pipe connection device.
According to a preferred aspect of the present invention, an assembly hole is formed in the coupling portion of the first pipe to which the guide holder is coupled, and the guide holder has a fixing plate that is in contact with the inner side surface of the assembly hole, And a main cover is formed at an upper end of the guide holder and formed with a protruding and retreating portion to be fitted into the fixing portion and is surrounded and connected to the wall.
According to a preferred aspect of the present invention, a pipe holder in the form of a circular tube is coupled to the inner periphery of the coupling portion of the first pipe, the pipe holder includes a guide holder insertion hole into which the guide holder is inserted, And a slit on which the first pipe is inserted.
According to a preferred aspect of the present invention, the guide holder is formed with an auxiliary wall to which the guide spring is coupled, one side is coupled to the guide spring, the slide member is inserted between the walls, A stopper portion for preventing advancement of the member is formed so that the slide member moves between the auxiliary wall and the stopper portion.
According to a preferred aspect of the present invention, the push button includes a pressing portion that covers an upper end of the main cover, and a locking wall that moves up and down between the main cover and the wall of the guide holder.
According to a preferred aspect of the present invention, a slide fit hole is formed in the wall between the stopper and the auxiliary wall, a lower end of the slide member is formed with a step portion to be inserted into the slide fit hole, Wherein the push button is formed with a releasing member formed at an inclination corresponding to the inclined portion of the slide member so as to press the slide member.
According to a preferred aspect of the present invention, a vertical insertion portion is recessed inside the wall of the guide holder, and a vertical member insertable into the vertical insertion portion is formed in the push button.
The present invention can freely extend or reduce a pipe by a simple operation of pushing a push button, and the number of constituent parts constituting the pipe joint device is remarkably reduced compared to the conventional one, thereby saving the manufacturing cost of the pipe joint device, .
