Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a liquid level gauge for detecting a liquid level used for an engine of an automobile or an A / T (automatic transmission), for example.

[0002]

[Prior art]

 Conventionally, an oil level gauge 100 as shown in FIG. 4 (a), for example, has been used for measuring the engine oil of an automobile. This oil level gauge 100 is provided with a long portion 102 inserted into a container through a guide pipe 101, a handle portion 103 provided at one end of the long portion 102, and a container provided at the other end of the long portion 102. The gauge section 104 is immersed in the liquid inside. In this case, the shape of the guide pipe 101 is almost straight.

As shown in FIG. 4 (b), the middle portion 105 of the long portion 102 called centering is bent and deformed so as to have the inner diameter width of the guide pipe 101, so that it can be moved laterally. It is regulated so that the gauge portion 104 is located at the center of the guide pipe 101.

[0004]

[Problems to be solved by the device]

 However, since many supplementary parts are installed around the recent automobile engines, the oil level gauge is often set in the gap between the parts, and the straight gauges are few.

In particular, since a gauge as shown in FIG. 4A cannot be inserted into a three-dimensional guide pipe, as shown in FIG. It uses materials such as springs that are easily deformed.

As for the centering of the gauge part, a conical ring 107 is inserted in the elongated part 106 such as a wire to cope with the centering.

Therefore, a process for manufacturing the gauge portion 104 and the long portion 106 and the number of days are required, resulting in high cost.

In addition, when one end of the elongated portion 106 is integrally formed with the handle 103 by insert molding, there is a problem that it takes more time to manufacture because it is manually performed by a human.

The present invention has been made in order to solve the above-mentioned problems of the prior art. The purpose of the present invention is to achieve a liquid level in a container even when the guide pipe has a two-dimensional or three-dimensional shape. An object of the present invention is to provide a liquid level gauge capable of easily and accurately measuring.

[0010]

[Means for Solving the Problems]

 In order to achieve the above object, according to the present invention, a long portion to be inserted into a container through a guide pipe, a handle portion provided at one end of the long portion, and a handle portion provided at the other end of the long portion are provided. In a liquid level gauge provided with a gauge part that is immersed in the liquid in the container, the long part is alternated along the longitudinal direction with a rigid part and a deformable part that is easily bent and deformed. It is characterized in that it is arranged.

The long portion, the handle portion, and the gauge portion are characterized by being integrally molded with resin.

[0012]

[Action]

 In the liquid level gauge having the above configuration, the deformed portion bends according to the shape of the guide pipe, and the gauge portion at the tip reaches the liquid level.

The rigid body part restricts the lateral movement within the guide pipe, and the gauge part is centered.

Further, by integrally molding the resin, the manufacturing is facilitated, the construction period is shortened, and the cost can be reduced.

[0015]

【Example】

 The present invention will be described below based on the illustrated embodiment. 1 and 2 showing a liquid level gauge according to an embodiment of the present invention, reference numeral 1 denotes an entire oil level gauge as a liquid level gauge, which is a long portion inserted into a container 3 through a guide pipe 2. 4, a handle portion 5 provided at one end of the elongated portion 4, and a gauge portion 6 provided at the other end of the elongated portion 4 and immersed in the liquid L in the container 3.

The elongated portion 4 has a configuration in which rigid portions 7 and deformable portions 8 that are easily deformed by bending are alternately arranged along the longitudinal direction. The shape of the rigid portion 7 is spherical in the illustrated example, but various shapes such as an abacus ball shape as shown in FIG. 2 (c) can be selected.

The long portion 4, the handle portion 5, and the gauge portion 6 are integrally molded with resin. As the resin material, a heat resistant resin such as 66 nylon or PBT is preferable. If elastic plastic is applied as the resin material, it will be more easily deformed and the application range will be expanded.

In the liquid level gauge with the above-described configuration, the liquid level is detected by wiping off the liquid such as oil attached to the gauge portion 6 and attaching the long portion 4 to the guide pipe 2 as in the conventional case. Insert the gauge part 6 into the liquid L in the container 3, extract again, and visually check the amount of immersion of the gauge part 6 in the liquid based on the liquid attached to the gauge part 6.

When the long portion 4 is inserted into the guide pipe 2, the deformed portion 8 bends according to the shape of the guide pipe 2 that is bent three-dimensionally, and the deformed portion 8 is guided by the guide pipe 2 to be guided by the guide pipe 2. Reaches the liquid level. Then, the rigid body portion 7 restricts the lateral movement within the guide pipe 2 to center the gauge portion 6.

3 (a) and 3 (b) show another embodiment of the present invention.

In the above-mentioned embodiment, a resin integrally molded product is used. In this embodiment, the elongated portion 14 is composed of a core metal 15 formed of a conventional bendable material such as a wire or a contact spring, and A rigid portion 17 is formed by joining a resin material or a rubber-like elastic body to the core metal 15 at a predetermined pitch. The deformed portion 18 is constituted by the core metal 15 between the rigid body portions 17. Further, the handle portion 5 is attached to one end of the cored bar 15, and the gauge portion 6 is attached to the other end.

[0022]

[Effect of device]

 The present invention has the above-described configuration and operation. Since the long portion to be inserted into the guide pipe is configured to be three-dimensionally deformable by alternately arranging the rigid portion and the deformable portion, the shape of the guide pipe is It can be easily inserted and the center of the gauge can be centered by the rigid part.

In addition, since the handle portion, the long portion and the gauge portion are formed as an integral resin molded product, there is no need to process parts such as the gauge portion and the core metal, or to perform a surface treatment process such as plating. Manufacturing becomes easy, the construction period is shortened, and the cost can be reduced.
