The present invention relates to an apparatus for alleviating the impact of a vacuum cleaner, and more particularly, to an impact alleviating apparatus having a structure for shock alleviation at a connection portion between a front end pipe and an extension pipe.

The vacuum cleaner is configured to remove dust in the room by allowing the intake fan to suck outside air through the hose by the rotation of the electric motor, and various types of extension pipes and brushes are connected to the front end of the hose.

Conventional vacuum cleaners as shown in Figure 1 of the drawing, the main body of the vacuum cleaner including a power supply and a control means for controlling the overall operation of the air intake device, dust collector and vacuum cleaner and supplying the operating power therein ( 1) is configured and connected to one end of the main body 1 and the corrugated pipe 3, which is flexibly bent so as to be able to rotate back and forth, left and right, is connected, and at the end of the corrugated pipe 3, various kinds of vacuum cleaners are connected. The handle 4 is configured with selection buttons for selecting an operation so as to be grasped by the user, and the front end pipe 5 and the extension pipe 6 are connected to the handle 4. The inlet part 7 of various forms is connected to the edge part of the extension pipe 6, and it is used.

In addition, the lower part of the main body 1 is formed with a convenient wheel 8, the coupling portion 9 is formed between the tip pipe 5 and the extension pipe (6).

The connecting portion (9) between the handle (4) and the tip pipe (1) or between the tip pipe (5) and the extension pipe (6) is engaged. Not only is it separable, but it is also sealed to block the inflow of external air so that the surrounding air cannot be sucked except for the strong air inflow through the suction unit (7).

However, in the conventional vacuum cleaner as described above, since the tip pipe, the extension pipe, the suction part, etc. of the handle other than the corrugated pipe 3 are all made of a hard synthetic resin material, and there is no separate shock absorber at the coupling part (connection part), In addition to the impact of the suction portion to the handle portion, the edge of the suction portion was worn or broken.

In other words, in the case of cleaning the corners of the room, the handle is pushed forward to clean it. At this time, the suction part hits the object provided in the room such as hard furniture, and the impact reaches the hand of the person who is cleaning. Or there was a defect that the impact is transmitted directly to the furniture, such as scratching or peeling off the coating (or paint) area.

The present invention aims to alleviate the impact received by the suction part during cleaning by allowing the coupling between the tip pipe and the extension pipe to fully overlap in order to solve the above-mentioned drawbacks.

The present invention for realizing the above object is inserted into the lower end of the end pipe to the upper end of the extension pipe is inserted so as to overlap a certain length, and hangs between the upper end of the extension pipe to the locking jaw caught between the operation installed on the outside of the lower end of the end pipe A spring is installed between the extension pipe and the end pipe so that the extension pipe receives the force downward, and a coupling portion of the extension pipe and the end pipe is covered with a pleat cover to block the connection from the outside.

The present invention will be described in detail with reference to the accompanying drawings.

The present invention is connected to the connecting portion (2) of the cleaner body 1, the corrugated pipe (3), the handle (4), the end pipe (5), the extension pipe (6) is installed and the end pipe (5) and the extension pipe (6) In the coupling part 9 to be formed, the spring 11 is held on the upper end 10 of the extension pipe 6 so as to be inserted into the lower end 12 of the tip pipe 5, and the tip pipe 5 is connected thereto. On the outside of the lower end 12 of the operation section 14 supported by the spring 13 is installed so that the engaging jaw 16 of the upper end 10 in the tip portion 15 of the operation interval 14 inside the tip pipe 5. To hang from, the outer side of the coupling portion (9) is to combine the wrinkle cover (17).

Unexplained reference numeral 18 is a perforated part perforated in the lower end 12 of the tip pipe 5, 19 is the axis of the operation period (14).

The upper end portion 10 of the extension pipe 6 is always under the force to exit from the lower end portion 12 of the tip pipe 5 by the restoring force of the spring (11).

As described above, the upper end portion 10 of the extension pipe 6 is acting to escape from the lower end portion 12 of the tip pipe 5, but the annular locking jaw 16 formed on the outer circumferential surface of the upper end portion 10 is in operation. It is caught by the tip 15 of (14) and can no longer retreat.

Since the actuating rod 14 has a force to always rotate the actuating rod 14 about the axis 19 by the self-spring 13 in the counterclockwise direction, the tip portion 15 of the actuating rod 14 has a tip. It protrudes into the pipe 5.

The tip portion 15 of the operation section 14 is in a bent state, and an inclined surface is formed at one side so that it is easy to insert the upper end 10 of the extension tube 6, on the contrary, the upper end 10 of the extension tube 6 is separated. When it is going to be caught in the annular locking jaw 16 is bent at the right angle of the tip portion 15 is prevented from being separated.

Therefore, when the extension tube 6 is to be detached, the tip 15 is rotated clockwise about the axis 19 by pressing the right side of the operation period 14 so that the tip portion 15 of the tip pipe 5 is removed. It is moved from the inside to the outside to separate the extension pipe (6).

The pleat cover 17 covers the spring 11 to improve aesthetics, and also prevents the user's finger from being caught in the spring 11 and the upper end 10 of the extension pipe 6 into the tip pipe 5. It is to get a sealing effect while giving room to prevent entry.

The present invention is to combine the extension pipe (6) and the end pipe (5) overlapping but there is an effect that can absorb the shock generated during cleaning by holding the spring 11 therebetween.
