Description

A level {A level}

The present invention relates to a spirit level using a transparent hose mainly used in construction sites, and more specifically, to form a fluid inlet for injecting a fluid into a transparent tube and to prepare a lid therein to store the inside. It is to provide a level so that the fluid can be stored and used without spilling.

Normally, in order to build a building, it is necessary to maintain the horizontal level. Those who are engaged in this situation are injecting a fluid such as water into a transparent tube made of PVC. Level level (水 방법 器) used in the above-described method is relatively inexpensive and widely used, but there is an inconvenience in that the fluid inside the fluid easily flows out and must be used after compensating for the fluid leaked out every time it is used. In addition, in winter, there is a problem in that the fluid injected inside to prevent freezing is completely discharged and stored, and then the fluid must be injected again in use.

The present invention is designed to solve the problems of the conventional leveler (水 수준 器) as described above to combine the inlet is provided with a lid to smoothly inject the fluid to both ends of the transparent tube of the leveler and the antifreeze inside The present invention has been completed with the technical problem of devising to provide a level that can be stored and used without leakage of fluid during storage by injecting a fluid containing the component.

1 is a perspective view showing a preferred embodiment of the present invention, Figure 2 is a cross-sectional view of the expansion portion of the present invention, it will be described below the level provided by the present invention (水準 器).

Level 1 of the present invention is to use a flexible transparent tube 2 made of approximately PVC, etc., both ends of the transparent tube 2 close to the transparent tube 2 by forcing the lower coupling tube 31 of the injection port 3 of the tube to be relatively easy to hold by hand. To be fixed.

The upper portion of the inlet 3 is integrally formed by the inlet 3 and the connecting rod 32 and a lid 33 having a handle 34 formed on one side thereof to open the fluid 4 during the injection or the work, and is closed during storage. Do not let the spill. In addition, the inlet 3 forms an inlet pipe 35 of the upper and lower straits as a countercurrent prevention means to block the fluid 4 that may suddenly flow out during the operation.

3 is a view showing another embodiment of the present invention, in which the fluid 4 can be injected into the outside with a backflow prevention means inside the injection hole 3 provided with a lid 33 as above, but the fluid 4 inside flows out to the outside. The check valve 36 is fitted to prevent it.

Combined with the cap 33 and the inlet 3 provided with a backflow prevention means at both ends of the level 1 of the transparent tube 2, which has the above-described configuration, the fluid 4 inside the transparent tube 2 is safely stored and used. It is so long.

That is, the present invention is used by integrating the lower fitting pipe 31 of the injection port 3 into the both ends of the transparent tube 2 by integrating, and opening the cap 33 of the injection hole 3 to inject the appropriate amount of fluid 4. In this case, the fluid 3 may be used as pure water, but may also be added to the user's convenience, and the anticoagulant pigment may be added in some cases to prevent the transparent tube 4 from freezing.

As described above, to check the horizontality by using the present invention in which the fluid 4 is stored in the state of injecting the fluid 4 into the transparent tube 2, the flow of the fluid 4 may be used after opening the lid 33 at the upper portion. Accurate measurement is made by doubling the color discrimination power by the dye, etc. If one injection port 3 is significantly lower than the other side due to inadvertent use, it blocks the fluid 4 which can suddenly flow out by the inlet pipe 35, so that the level 1 can be used safely. It will be possible. In this way, when storing the present invention after use, the lid 33 at the top of the inlet 3 is closed to shield the outside so that the fluid 4 does not flow out, and the transparent tube 2 is wound and stored.

When the check valve 36 is coupled to the inlet 3 as shown in FIG. 3, the outflow of the fluid 4 inside the transparent tube 2 is more effectively blocked, thereby further improving the effect of the present invention.

In this way, the present invention is to be used to open the lid 33 when necessary, and to be stored by closing the lid 33 when storing.

As described in detail above, the present design level 1 combines the inlet 3 provided with a lid 33 to smoothly inject the fluid 4 into both sides of the transparent tube 2, and injects the fluid 4 containing the antifreeze component therein. The following effects can be obtained.

1) Can be stored and used without leaking the inner fluid by the lid.

2) Even if the level of both sides of the level is suddenly changed during use, the outflow prevention means provided in the inlet can minimize the outflow of the fluid.

3) The colorant or antifreeze component is added to the injected fluid to make it easy to identify and can be used without risk of freezing, especially in winter.

The present invention that can be obtained in various aspects as described above is able to be distributed at a low price, so it is a very good design that can be conveniently used in construction sites and the like.
