Abstract

PROBLEM TO BE SOLVED: To easily distinguish a seal member from other seal members of the same kind. SOLUTION: An O-ring 4 preventing the leaking of oil from a shaft part in the hydraulic power unit of a hydraulic elevator comprises a transparent body 5 and a display color member 6 sealed inside the transparent body 5. For example, three kinds of O-rings 4 provided to match three different kinds of hydraulic elevators have respective color members 6 each given a single different color, i.e., red, blue, and yellow. The O-rings 4 can be distinguished from one another by viewing those colors.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a seal member such as an oil seal provided in a hydraulic power unit of a hydraulic elevator.

[0002]

2. Description of the Related Art FIG. 5 is a plan view showing a conventional sealing member, for example, an O-ring. The O-ring 1 prevents oil leakage from a shaft portion in a hydraulic power unit of a hydraulic elevator, for example, and is entirely formed of a black annular member. In a hydraulic elevator, a plurality of O-rings 1 having different inner diameters 2 and outer diameters 3 are prepared in advance according to the type of the hydraulic elevator. That is, a different O-ring 1 is provided for each hydraulic elevator model. When the O-ring 1 is worn due to aged deterioration or the like, a maintenance person performs an operation of replacing the O-ring 1 with a new O-ring 1.

[0003]

By the way, the above-mentioned O
Since all of the ring 1 is made of black, when a maintenance person replaces it with a new one, an O-ring 1 that does not match the corresponding model may be prepared or may be attached by mistake. . For this reason, there has been a problem that the efficiency of the replacement work of the O-ring 1 tends to decrease.

The present invention has been made in view of the above-mentioned circumstances in the prior art, and an object of the present invention is to provide a seal member which can be easily distinguished from others of the same kind.

[0005]

In order to achieve the above object, according to the first aspect of the present invention, there is provided a sealing member for sealing a fluid, a transparent body, and a display sealed inside the transparent body. And a color member.

According to the first aspect of the present invention, the color member is made different in color, or the arrangement of colors is changed, so that the color member can be easily distinguished from others of the same type. And can be attached to a place to be used without error.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a seal member according to an embodiment of the present invention.

FIG. 1 is a plan view showing a first embodiment of the present invention, and FIG. 2 is a sectional view taken along line AA of FIG.

The first embodiment shown in FIGS. 1 and 2 is, for example, an O-ring 4 for preventing oil leakage from a shaft portion in a hydraulic power unit of a hydraulic elevator. And a display color member 6 enclosed therein. The O-rings 4 are provided in three types corresponding to, for example, three types of hydraulic elevators having different sizes. It is composed.

In the first embodiment configured as described above,
There is an O-ring 4 having a different color of the color member 6 corresponding to the type of the hydraulic elevator, and when replacing the O-ring 4 of the corresponding model, the replacement work is performed using the O-ring 4 of the color member 6 of the corresponding color. This can be easily performed, and it can be easily visually distinguished from others of the same type, and the maintenance staff can efficiently perform the replacement work of the O-ring 4 of the corresponding model.

FIG. 3 is a plan view showing a second embodiment, and FIG.
FIG. 7 is a plan view showing a third embodiment.

The second embodiment shown in FIG.
And an O-ring 10 composed of a first color member 8 and a second color member 9 for display enclosed in the transparent body 7. The O-ring 10 is, for example, a hydraulic elevator 3
Three types are provided corresponding to the three types, and the first one of the O-rings 10 is set such that the color of the first color member 8 is set to red and the color of the second color member 9 is set to black. In the second, the color of the first color member 8 is set to red, the color of the second color member 9 is set to blue, and in the third, the color of the first color member 8 is set to red. , The color of the second color member 9 is set to yellow. For example, the first color member 8 indicates the inner diameter, and the second color member 8 indicates the second color member.
The color member 9 indicates an outer diameter.

[0013] In the second embodiment constructed as described above, similarly to the above-described first embodiment, it is easy to visually distinguish the same type from the others, and the maintenance staff can check the corresponding items. To replace the O-ring 10 of the model
It can be performed efficiently. In the second embodiment, in particular, the first color member 8 and the second color member 9
By looking at the color, the maintenance person can grasp how the O-ring 10 has the inner diameter and the outer shape set.

The third embodiment shown in FIG.
And an O-ring 15 composed of a first color member 12, a second color member 13, and a third color member 14 for display enclosed in the transparent body 11. The O-rings 15 are also provided in three types, for example, corresponding to three types of hydraulic elevators. The first one of the O-rings 15 has a first color member 12 of red color and a second The color of the color member 13 is set to blue, the color of the third color member 14 is set to black, and the second is that the color of the first color member 12 is yellow and the second color member 1 is yellow.
The third color is set to red, the color of the third color member 14 is set to black, and the third color is set to blue for the first color member 12 and to yellow for the second color member 13. , The color of the third color member 14 is set to black. For example, the first color member 12
Is the inner diameter, the second color member 13 is the outer diameter, and the third color member 1 is
Reference numeral 4 denotes the year of manufacture.

[0015] Even in the third embodiment configured as described above, similarly to the second embodiment described above, the first color member 1 is formed.
Since the second color member 13 is provided, the same operation and effect as those of the second embodiment can be obtained, and the third color member 14 can be provided.
By looking at the color of, the maintenance staff can grasp the production year of the O-ring 15.

In the above embodiments, the O-ring is used as the seal member.
In addition to the seal member provided in the hydraulic elevator,
Any material that seals a fluid is applicable.

[0017]

According to the present invention as described above, the color of the color member put into the transparent body can be visually checked, so that the color member can be easily distinguished from others of the same type. The replacement of the corresponding seal member can be performed more efficiently than in the past.
