Description

[Detailed description of the invention] This invention relates to an air hose winding machine that sends compressed air, and is related to an improvement of a water hose winding machine that sends tap water.The purpose of this invention is to create an inexpensive air hose winding machine. is to provide.

The advantage of a water hose winder is that it is inexpensive, but when used as an air hose winder, the pressure of compressed air is generally several times higher than that of tap water; Because the structure is such that the welded frame receives the thrust caused by the welding, the frame may be damaged, or misalignment of the welding may cause the O-ring that maintains airtightness to become misaligned with its sliding surface, causing compressed air to leak. There is an important point that it is easy.

The present invention was developed based on the idea that it would be most rational to improve the low-cost water hose winding machine to eliminate the above-mentioned isthmus, and to create a structure in which the thrust caused by air pressure does not act on the frame, and also to improve the Considering the properties of the agent, we decided to use the molded parts of the water hose winder as is, and by improving only the drum shaft, which is easy to modify, we were able to create an inexpensive air hose winder.

This will be explained below with reference to the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes a frame of the winding machine, which has a welded structure.

4 and 5 are drum shafts, the inner shaft ends of which are welded to the drum 2 as shown in FIG.

Reference numeral 7 denotes a thread, which is welded at both ends to the pedestal 1, and a bearing 8 is formed in the center to support the drum shaft 4.

Reference numeral 3 denotes a handle for rotating the drum 2, which is attached to the outer shaft end of the drum shaft 4.

Reference numeral 9 denotes a reel, and both ends thereof are fixed to the pedestal 1 by ports 11, and a bearing 10 is formed in the center to support the drum shaft 5.

In FIG. 3, an air passage 6 is provided at the center of the drum shaft 5.

12 is an inlet joint, and an air passage 13 is provided in the center.

An O-ring 17 is attached to the left end of the inlet joint 12 (hereinafter referred to as the same in the drawings) and is rotatable around the inner circumference of the air passage 6 in an airtight manner.

16 is an annular groove provided at the rear of the O-ring 17.

Reference numeral 18 denotes a rod tip type set screw which is screwed into the female thread of the outer diameter of the drum shaft 5 so that its rod tip can rotate within the annular groove.

Reference numeral 14 denotes a screw provided at the outer upper end of the inlet joint 12 for connecting it to an air tank of a compressor (not shown).

Reference numeral 15 denotes a rotation stopper provided below the screw 14.

Reference numeral 19 denotes a rotation stop plate, whose rotation stop part 20 is inserted into the rotation stop part 15, and the other side is fixed to the drum 9 with a bolt 21, and when the drum 2 is rotated by the handle 3, the friction of the O-ring 17 prevents the inlet from closing. This prevents the joint 12 from rotating.

Reference numeral 22 denotes an outlet pipe, which is curved as shown in FIGS. 1, 2, and 3. One end is inserted into the air passage 6 and welded, and the other end passes through the hole 24 in the drum 2. It protrudes from the surface, and a screw 23 is provided at the tip.

The screw 23 is for connecting an air hose (not shown).

The effects of the present invention will be described.

The drum shafts 4 and 5 are respectively welded to the center of each end of the drum 2 and supported by bearings 8 and 10, and the handle 3 is fixed to the drum shaft 4.

Therefore, when the inlet screw 14 is connected to an air tank (not shown), the outlet screw 23 is connected to an air hose (not shown), and the handle 3 is turned, the air hose is wound around the drum 2. .

Drum 2 can be removed by pulling the end of the wound air hose.
rotates in the opposite direction, the air hose unravels from the drum 2, and its tip can be brought to the desired position, so if compressed air is sent from the air tank, work can be done using compressed air.

In Fig. 3, considering the common use of parts between the air hose winding machine and the water hose winding machine, it is desirable to use molded products such as pressed products, so the outer diameter of the drum 5 is equal. There is a need to.

If the compressed air pressure is P and the diameter of the air passage 6 is d, the thrust due to this pressure will be 1147rd2P.

This thrust is received between the annular groove 16 and the rod tip set screw 18 screwed into the female thread of the drum shaft 5, so if you look at it as a result, the thrust that pushes the drum shaft 5 to the left and the right This results in a thrust force that pushes it in the opposite direction, and since the two are in balance, no thrust force acts on the pedestal.

The inlet joint 12 to which the O-ring 17 is attached is attached to the drum shaft 5.
An air passage 6 provided inside is inserted as a guide,
The thrust is balanced within the drum shaft 5 and is not affected by structural deviations, so the centers of the air passage 6 and the O-ring 17 are always aligned, so there is no leakage from the O-ring 17. There isn't.

Since the number of bar tip set screws can be increased according to the magnitude of the thrust, the winder of the present invention can also be used as a winder for high-pressure air hoses.

As described above, the present invention has a structure in which the thrust force does not act on the frame even though the compressed air pressure is several times higher than the tap water pressure. With only a few improvements, it can be used as an air hose winder.

Therefore, the air hose winding machine of the present invention is inexpensive and can be used for high-pressure air, so it can be used to wind air hoses that send compressed air to mobile road air machines and construction air machines that use compressed air. It is very useful as a cutting machine.
