As shown in Figures 1 to 3, the integrated pipe length adjusting device (A) according to the present invention, the inner pipe 100 is formed with a plurality of engaging grooves on the outer surface, the inner pipe 100 is slidable In the integrated pipe length adjustment device configured to be inserted and coupled to the pipe connecting portion is configured, the length of the pipe is adjusted by the elastic action, the fixed length of the adjustable pipe,

A guide tube (2) coupled to the inner pipe (100), having a stopper member integrally formed at one side thereof, and a spring clamp (6) elastically fixedly coupled to the other side by springs (61, 61 ');

And a control knob 4 inserted and coupled to an outer circumference of the guide tube 2 and having a pressing piece 22 corresponding to the stopper member on an inner circumferential surface thereof.

The guide pipe 2 is formed as a cylindrical body fitted to the outer periphery of the inner pipe 100 and has first and second mounting grooves 21 and 23 formed on one side thereof and has a front end portion and a rear end portion 28 are protruded and formed on the upper and lower ends 28 of the front end and the rear end of the guide groove 282 so that the pushing piece 22 can pass through the guide groove 282.

And the receiving portion 24 is formed on the other outer peripheral surface of the guide tube 2 so that the spring clamp 6 can be mounted.

The stopper member,

One end is integrally formed in the first and second mounting grooves 21 and 23, and includes first and second stoppers 3 and 3 'having elasticity, and the first and second stoppers 3 and 3. At the other end of '), a locking protrusion 31 inserted into the locking groove 104 of the inner pipe 100 is formed.

The first and second stoppers 3 and 3 ′ are preferably disposed in the first and second mounting grooves 21 and 23 of the guide tube 2 such that the engaging protrusions 31 are symmetrical.

 Preferably, the first and second stoppers 3 and 3 'are plate-shaped in a rectangular shape, and one end thereof is coupled with the shaft pin 32, and the other end thereof is inserted into the engagement groove 104 of the inner pipe 100 31 are formed.

The engaging protrusion 31 is preferably hemispherical in consideration of the fact that the engaging groove 104 is hemispherical.

In addition, the grooves 30 are formed on the upper surfaces of the first and second stoppers 3 and 3 'so that the pressing pieces 22 are inserted, and the inner surfaces of the grooves 30 correspond to the inclined surfaces of the pressing pieces 22. The inclined surface is formed.

On the other hand, the pressing knob 22 corresponding to the first and second stoppers 3, 3 'is formed on the inner circumferential surface of the cylindrical tube body, and the adjusting knob 4 is formed of a cylindrical tube fitted and coupled to the outside of the guide tube 2. [ do.

The pressing piece 22 is formed to protrude to the inside of the control knob 4 is formed separately in the front and rear to correspond to the first and second stoppers (3, 3 '), respectively, in particular each pressing piece (22) ) May be inserted into the grooves 30 of the first and second stoppers 3 and 3 'by being cut in a lower portion.

The pressing piece 22 is formed to have an inclined surface at both ends to facilitate entry, so as not to collide with the ends of the first and second stoppers 3 and 3 'and to be smoothly pressed, and to be easily moved, and formed in a substantially trapezoidal shape.

Accordingly, the pressing piece 22 is inserted into the recess 30 of the first and second stoppers 3 and 3 ', thereby releasing the pressing force, and the first and second stoppers 3 and 3' are restored by the restoring force. It returns to the horizontal state.

On the other hand, the spring clamp 6 is inserted into the receiving portion 24 formed on one side of the guide tube 2, the first and second springs 61 and 61 'are coupled to both sides to have an elastic force.

Hereinafter, the operation of the present invention will be described.

When holding the adjusting knob 4 and holding the inner pipe 100 with the other hand and applying a force in the direction of increasing or decreasing the length of the integrated pipe length adjusting device A, the spring clamp is coupled to the guide pipe 2. 6) moves in the direction of the force, the spring (6, 6 ') of one of the first and second springs is further compressed and the other spring (61, 61') is relaxed and the spring clamp (6) It moves in the direction of the force.

As described above, the spring clamp 6 moves in one direction and simultaneously presses the upper portions of the first and second stoppers 3 and 3 'located in the engaging groove 104 of the inner pipe 100 ( When 22 is pressurized, the first and second stoppers 3 and 3 'bend downward, and the locking protrusion 31 is inserted into the locking groove 104 to be in a fixed state.

On the other hand, when the adjusting knob 4 is moved forward or backward, the pressing piece 22 is inserted into the groove while sliding the upper surfaces of the first and second stoppers 3 and 3 ', so that the first and second stoppers 3 and 3' are inserted. ), The pressing force is released.

Accordingly, the first and second stoppers 3 and 3 'are returned to their original horizontal state by the elastic restoring force, so that the locking protrusion 31 is separated from the locking groove 104 to be released, thereby allowing free movement. .

Therefore, the length of the pipe can be adjusted by further inserting the inner pipe 100 into the inside of the outer pipe 200 or vice versa.

Although the present invention has been described in connection with the above-mentioned preferred embodiments, it will be apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the invention, It is obvious that the claims fall within the scope of the claims.
