Description

Buoyancy Tube with Air Valve {AIR VALVE TUBE}

The present invention relates to a rubber tube equipped with an air valve, and in particular, maintains the state after the valve mounted in the tube is opened or closed by a single external force action, and is safer as a double sealed structure, and the air injection And it relates to a buoyancy generating tube is equipped with an air valve that is easy to use to discharge quickly.

Buoyancy generating tubes used in the sea or wide lakes, etc., should be made of thick fabrics that make up the fuselage in consideration of safety.

Therefore, a tire tube is also used, which is equipped with a separate air valve to inject or discharge air into the tube.

Hereinafter, the buoyancy generating tube equipped with the conventional air valve manufactured using the tire tube is demonstrated.

1A is a perspective view of a buoyancy generating tube equipped with a conventional air valve, and FIG. 1B is a cross-sectional view taken along line AA ′ of FIG. 1A.

In the conventional buoyancy generating tube, a valve stem (Valve Stem) is protruded on the tube surface when the air valve is mounted.

Only a flange 10 is inserted into the tube and a washer 9 and a tightening nut 8 are engaged with the tube shell 7 therebetween to secure the air valve to the tube 7.

When air is to be injected, an injection section of a separately provided air injector (not shown) is inserted into the valve stem inlet and generally has a tip portion (not shown) at the end of the injection section (not shown). Is provided to push the valve core 2 in the valve stem 1 downward when inserted. Accordingly, as the spring 4 is compressed, the valve core 2 moves downward, and the first and second sealing rings 5-1 and 5-2 inserted into the valve core 2 also move downward. The second vents 3-1 and 3-2 are opened, and air flows through the vent pipe 6 connected to the inside of the tube, so that the air can be injected.

However, the conventional buoyancy generating tube having such a structure carries a risk that the user's skin may be scratched or torn on the valve stem during buoyancy generation because the air valve protrudes a lot out of the tube. In addition, it is inconvenient because the person who puts the air must keep supporting it by hand so that the air inlet part does not escape from the valve stem during air injection, and because the cross section diameter of the valve stem is small, the vent section cross-section radius is small accordingly. Not only does it take a lot of time, but there are also inconveniences such as a person having to keep pressing the upper surface of the valve core to keep the air valve open.

The purpose of the present invention is to maintain the state after opening or closing the valve mounted in the tube by one external force action in order to improve the problem of the buoyancy generating tube equipped with a conventional air valve, and the double sealed structure It is intended to provide a buoyancy generating tube equipped with an air valve that is safe against air leakage, quick and easy to inject and discharge air, and can be used more safely because the projection does not extend long on the tube surface.

In order to achieve the above object, the present invention provides a tubular valve body having first and second vents respectively formed on the upper side and the lower side for injecting and discharging the air in the tube, and installed in the valve body to open and close the second vent. Combined with the valve core and the first vent of the valve body to maintain the second vent in a closed or open state while maintaining a fixed state in the upper or lower position when the external force is removed while linear movement up and down by the elastic restoring force An air valve comprising an upper cap capable of disassembling and a lower cap coupled to a lower portion of the valve body to fix the valve body to the tube is installed at a portion having a thicker thickness than the other portions of the tube fabric shell. .

The tube of the present invention is manufactured using a tire tube.

The valve body is formed with a spiral for coupling with the upper cap or the inlet of a separate air injection means on a portion of the upper inner wall of the body, and the inside of the body is connected and fixed by a support bar extending at a predetermined position of the inner wall portion and the center of the tube Ring-shaped fixing ring tube is formed.

The valve core has a core cap having an inclined end formed at a lower outer periphery, and a core having a first locking groove coupled to the core cap and having a second locking groove and a length of the groove longer than the second locking groove in the center portion of the outer circumference of the body. Torso, core cap and core body above the anchor ring tube An elastic member inserted around the tube, a locking ring case coupled to a lower portion of the fixed ring tube,

It is installed inside the fixed ring tube and the hook ring case and includes a hook ring formed with a protrusion on the inner circumferential surface, and a second seal ring inserted into the bottom of the core body to seal or open the second vent according to the position of the core body. . At this time, each time the external force acts on the upper surface of the core cap, the inclined end and the locking ring protrusion are contacted by the downward movement of the core cap, and thus the circumferential distance between the first and second locking grooves in which the locking ring is the horizontal length of the inclined end. Rotates as much as the locking ring projection is in the position where it can be caught in the first or second locking groove, the locking ring in the position of the first or second locking groove during the upward movement of the valve core by the restoring force of the elastic member When the projection is caught in the first catching groove, the valve core moves upward along the first catching groove to the initial position, thereby closing the valve. When the catch is caught in the second catching groove, the valve core is stopped to maintain the valve opening state. It is characteristic to let.

Moreover, a protrusion tube with a spiral is formed in the center of the lower surface of an upper cap, and the 1st sealing ring which seals a 1st vent is inserted in the protrusion tube.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Buoyancy generating tube of the present invention is manufactured using a tire tube.

Therefore, the fabric sheath forming the body of the tube is overall thick to ensure stability.

Figure 2a is a perspective view of a buoyancy generating tube equipped with an air valve according to the present invention, Figure 2b is a cross-sectional view BB '.

Around the mounting portion of the air valve 15, the surface of the tube 16 continues to receive surface tension due to the coupling force between the lower cap 48 and the flange 25 according to the mounting of the air valve to the tube.

Accordingly, the tube 16 surface around the air valve 15 mount is much weaker to external impact or air pressure in the tube 16 than other surfaces of the tube.

If the air valve 15 is installed at the same thickness as the other surface of the tube, the thickness of the tube around the valve mounting portion becomes thinner due to the valve mounting. There is a high risk of occurrence.

Therefore, in the buoyancy generating tube 16 of the present invention, the air valve 15 is installed at a portion 17 formed thicker than other portions of the outer shell of the tube, and generally one side of the inner circumference of the tube body of the outer shell of the tube. There is a part 17 in which the skin is formed thicker than the other part, and the air valve is mounted to the part.

Figure 3a is a partial cross-sectional view showing a closed state of the valve, Figure 3b is a partial cross-sectional view showing a state in which the valve is opened by the external force is applied to the core cap and Figure 3c is a view showing the open state of the valve even after the external force applied to the valve is removed Partial cross section shown.

4A and 4B are front sectional views of the upper cap and the lower cap, respectively. FIG. 5A is a top plan view of the valve body, FIG. 5B is a cross-sectional view of the locking ring and the locking ring case, and FIG. 5C is an upper portion of the locking ring and the locking ring case. Top view.

The air valve 15 mounted on the tube 16 has a tubular valve body 20 and an upper cap 45 capable of opening and closing the first vent 21-1, which is an opening portion above the valve body. The valve core 30 is inserted into the valve body 20 to open and close the second vent 21-2, which is an opening of the lower part of the valve body, to control the air injection and discharge into and out of the tube 16, and the valve body ( 20 is composed of a lower cap 48 covering the lower portion.

The valve body 20 has a tubular shape and has an upper / lower opening, which is the first vent 21-1 and the second vent 21-2. The lower cap 48 inserted into the tube 16 to secure the valve to the tube is joined to squeeze against a flange 25 formed on the upper portion of the body with the tube shell 16 interposed therebetween. Since the air valve 15 is installed so that all of the lower portion of the flange 25 enters the tube, the portions exposed to the outside of the tube are the upper cap 45 and the portion protruding slightly above the flange 25 of the valve body.

When the buoyancy tube 16 is used, an upper cap 45 is used to protect the air valve 15. The upper cap 45 has a flat shape, and the upper cap 45 has a flat surface when coupled to the valve body 20. There are very few protruding parts from.

When air is injected into the tube, the upper cap 45 is separated from the valve to expose the first vent 21-1.

In addition, a spiral 22-1 is formed on an inner surface of the upper portion of the valve body 20, which is for coupling with the upper cap 45 but is provided separately from the air injector (not shown). It is for coupling with the inlet. The air inlet port uses a spiral formed on the outer wall surface.

Therefore, when the air is injected, the air inlet (not shown) inserted into the air valve 15 through the first vent 21-1 is coupled with the air valve 15 by a screwing method, so that a person keeps the air injector. Even if not grasped and supported, it is not separated from the air valve 15.

In addition, the upper cap 45 is connected to the upper portion of the valve body 20 by a connecting string 45-1. A circular protrusion tube 47 having a spiral is formed on the outer surface of the upper cap 45 at the center thereof. The upper cap 45 is coupled to the screw 22-1 of the upper inner surface of the valve body 20 in a screwed manner. At this time, the first sealing ring 46 is inserted into the outer circumference of the protruding pipe 47 to enhance the air leakage preventing function when the upper cap 45 is coupled.

The spiral 22-2 is also formed on the outer surface of the lower portion of the valve body 20 so that the lower cap and the screw can be coupled together. In addition, a fixed ring tube 24 supported by a plurality of support bars 23 extending from the inner wall is formed at the center of the tube inside the valve body 20. The through hole is formed in the center of the fixed ring tube 24. The locking ring case 39 is coupled to the lower portion of the fixing ring tube 24, and the locking ring 40 is placed in the space between the fixing ring tube 24 and the locking ring case 39.

The engaging ring 40 has a thin ring shape, and protrusions 40-1 are formed on both sides of the inner circumferential surface thereof.

The valve core 30 is formed by combining the core body 35 and the core cap 32. The core cap 32 is located above the fixed ring tube 24, and the core body 35 is fixed ring tube and the locking ring. 40 is inserted to extend through the locking ring case 39 to the lower portion of the locking ring case. At this time, a spring 38, which is an elastic member, is inserted between the core cap 32 and the fixed ring tube 24 to generate an elastic force against the external force transmitted from the core cap 32.

In addition, a second sealing ring 41 having the same diameter as the second vent is inserted in the lower portion of the core barrel 35 so as to seal the second vent 21-2. The first locking grooves 36-1 and the second locking grooves 36-2 having different depths are formed so that the projections 40-1 formed on the locking ring 40 can be inserted into and hooked.

At this time, the depth of the first locking groove (36-1) should be formed longer than the height of the fixing ring tube (24). This is to allow the valve core 30 to return to its original position when the projection 40-1 of the locking ring is caught by the first locking groove 36-1.

The lower cap 48 having the spiral 48-1 formed therein is coupled to the spiral 22-2 formed on the lower outer wall of the valve body 20. The upper flange 25 and the lower cap 48 strongly press the far-end shell 17 together so that the valve 15 is fixed to the tube.

At this time, the fabric protection washer 48-2 is inserted between the lower cap 48 and the installation part shell 17.

Hereinafter, the valve opening and closing operation of the buoyancy generating tube equipped with the air valve of the present invention will be described.

The air valve 15 of the present invention not only opens or closes the valve by one external force but also maintains the state until a new external force is applied.

The operation of opening the closed valve to maintain the open state will be described.

When the air valve 15 is closed and the external force is applied by pressing the core cap 32 inside the valve body 20, the core cap 32 and the core body 35 are fixed to the ring tube 24 and the locking ring case ( 39) and downward movement through the holes formed in each of the center of the engaging ring 40 placed therebetween.

Therefore, the second sealing ring 41 inserted below the core body 35 and closing the second vent 21-2 descends together and opens the second vent 21-2 to open the valve.

At this time, the spring 38 surrounding the valve core 30 is supported so as to span the jaw 24-1 of the upper portion of the fixed ring tube and is compressed without passing through the hole.

In addition, since there is no change in the vertical positions of the fixing ring tube 24, the locking ring case 39, and the locking ring 40, the lower end of the core cap 32 and the locking ring 40 come into contact with each other by the downward movement of the core cap 32. But, the inclined end 33 is formed on the lower outer periphery of the core cap 32 so that the projection 40-1 of the engaging ring in contact with the inclined end 33 moves along the inclined end according to the downward movement of the core cap. Will rotate.

Therefore, the position of the locking ring projection 40-1 is changed by rotating by the horizontal distance of the inclined end 33.

The core cap 32 and the core body 35 move upward again by the restoring force of the spring 38. At this time, the locking ring 40 is caught by the jaw 24-2 of the lower surface of the fixing ring tube 24. I can't go up anymore. At this time, since the locking ring protrusion 40-1 is in the same position as the second locking groove 36-2 of the core body 35, the locking ring protrusion 40- is in the second locking groove 36-2. 1) is caught so that the core body 35 does not return to its original position and stops movement at that position, so the air valve 15 remains open.

Similarly, if the upper surface of the core cap 32 is pressed again, the core cap descends again and comes into contact with the locking ring projection 40-1, which may catch the first locking groove 36-1 along the inclined end 33. Rotate to position. At this time, as described above, the first locking groove 36-1 is formed much deeper than the second locking groove 36-2.

Therefore, when the core body 35 moves upward by the restoring force of the spring 38 by removing the force on the upper surface of the core cap 32, the locking ring protrusion 40-1 is applied to the first locking groove 36-1. Even if caught, the length of the groove is longer than the height of the fixed ring tube so that the core body 35 can continue to move up and return to the initial position. Thus, the valve is closed.

Therefore, the present invention has a locking ring and the first and second locking grooves are installed so that the state is maintained until the external force is applied to the valve while the valve is opened or closed by one external force, so that the air is easily injected and discharged. Since the spiral is formed on the upper inner surface of the valve body, the inlet of the air injector, which is separately provided during the air injection, is coupled to the upper opening of the valve by a screw coupling method, so that the inlet is not separated from the valve during the air injection.

And, most of the components of the air valve mounted on the tube is inserted into the tube so that there is almost no portion protruding out of the outer shell, there is no risk of damaging the human skin when the buoyancy is generated, and damage to the existing tube Compared with the valve, the vent diameter is large, which shortens the air discharge and injection time, and enables air injection even at low pressure. In addition, when the upper cap is coupled to the valve, there is no risk of air leakage because the inner air is sealed by the two sealing rings, and furthermore, since the tire tube is used as the tube material, the safety is enhanced.
