[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to improvement of a level gauge. The level gauge of the present invention is mainly used as an oil level gauge.

[0002]

[Prior art]

 In the known level gauge, as shown in FIG. 2, a guide portion 21 provided with a gauge portion 22 at its lower end and a handle portion 23 having a rounded upper end are connected via a pipe body 24, and these three parts 21, 23, A long connecting body made of 24 is inserted into a mold (not shown), and a packing portion 25 made of a rubber-like elastic material is vulcanized and simultaneously vulcanized and bonded to the outer periphery of these three parts 21, 23, 24. is doing. The guide part 21 and the handle part 23 are divided into two parts because the guide pipe (not shown) into which the inner part 21 is inserted may be bent two-dimensionally or three-dimensionally. This is because the grip portion 23 is required to have rigidity in order to improve workability of inserting and removing the guide pipe, while the flexibility of 21 is required.

However, according to this level gauge, when the under-neck dimension a ₂ is changed, the guide portion 21 must be replaced with a component of another specification regarding the length, and the guide portion 21 of the different specification is also used. Since this will be inserted into the mold during vulcanization molding of the packing portion 25, there is the inconvenience that the mold must be replaced with one having a different specification.

In order to solve this inconvenience, the applicant of the present application first forms the entire grip portion 41 with a tubular body as shown in FIG. Then, the guide portion 43 is inserted into the lower end of the handle portion 41 by a predetermined length b ₃ , and the lower end of the handle portion 41 is caulked, or the guide portion 43 is fixed to the handle portion 41 by soldering. A level gauge was proposed (see Japanese Utility Model Laid-Open No. 2-6224). And according to this level gauge, only by changing the insertion length b ₃ of the guide portion 43 without changing the guide portion 43 and the mold, it is possible to change the under head size a _3.

[0005]

[Problems to be solved by the device]

However, in this level gauge, when the neck size c ₃ is changed, the grip portion 41 must be replaced with a component of another specification with respect to its length, and the grip portion 41 of the other specification is packed. There is a problem that the mold must be replaced with another one because it is inserted into the mold during the vulcanization molding of the part 42. In recent years, for example, automobile engines have been diversified, and the mounting positions of the guide pipes in the engine room have been varied, so that there are many opportunities to change the neck size c ₃ .

[0006]

[Means for Solving the Problems]

 In view of the above points, the present invention has been devised to solve the above-mentioned problems in the prior art, and in order to achieve this object, a packing part and a lower end and It is fixed to the pipe by inserting the pipe with the upper end protruding from the packing part and the lower end of the pipe by a predetermined length, and caulking the lower end of the pipe, or by soldering. The guide part, a gauge part provided at the lower end of the guide part, and a predetermined length at the upper end of the pipe body, and the pipe body is caulked at the upper end of the pipe body or by soldering. A level gauge consisting of a handle portion fixed to the body is provided.

[0007]

[Action]

 The level gauge of the present invention having the above structure is manufactured by the following procedure. That is, first, the tubular body is individually inserted into a mold, and the packing portion is vulcanized and bonded to the outer periphery of the tubular body simultaneously with vulcanization molding. Next, insert the guide part into the lower end of the tube for a predetermined length, and then fix the guide part to the tube by caulking the lower end of the tube or by soldering. The grip portion is inserted in a predetermined length, and the grip portion is fixed to the pipe body by caulking the upper end of the pipe body or by soldering. Therefore, according to the level gauge of the present invention, the under-neck dimension and the over-neck dimension can be respectively changed only by changing the insertion lengths of the guide part and the grip part without changing the guide part, the grip part and the mold. Can be changed.

[0008]

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings.

In FIG. 1, reference numeral 1 is a packing portion made of a rubber-like elastic material, and a tubular body 2 made of a steel pipe is inserted into the packing portion 1 with its upper end and lower end protruding. . Seen from the packing part 1, the packing part 1 is vulcanized and bonded to the outer periphery of the tubular body 2. The upper end of the guide portion 3 made of a wire is inserted into the lower end of the tubular body 2 by a predetermined length b ₁ , and the lower end of the tubular body 2 is caulked to fix the guide portion 3 to the tubular body 2. The gauge portion 4 is provided at the lower end of the guide portion integrally or separately. The lower end of the handle portion 5 made of a round bar with a rounded upper end is inserted into the upper end of the tubular body 2 by a predetermined length d ₁ , and the upper end of the tubular body 2 is caulked, whereby the handle portion 5 is attached to the tubular body 2. Is stuck.

The level gauge having the above structure is manufactured by the following procedure. That is, first, the tubular body 2 having a predetermined length is individually inserted into a mold (not shown), and the packing portion 1 is vulcanized and bonded to the outer periphery of the tubular body 2 at the same time as the vulcanization. Next, the upper end of the guide portion 3 is inserted into the lower end of the pipe body 2 by a predetermined length b ₁ , and the lower end of the pipe body 2 is caulked to fix the guide portion 3 to the pipe body 2, and before and after this, The lower end of the handle portion 5 is inserted into the upper end of the tubular body 2 by a predetermined length d ₁ , and the upper end of the tubular body 2 is caulked to fix the handle portion 5 to the tubular body 2. The fixing means may be soldering instead of caulking.

Therefore, according to the level gauge, the insertion length b ₁ of each of the guide portion 3, the handle portion 5 and the mold is not changed and the guide portion 3 and the handle portion 5 are inserted into the tube body 2. , D ₁ can be changed to change the under neck size a ₁ and the above neck size c ₁ , respectively. Further, since only the tubular body 2 is inserted into the mold, the mold can be simply downsized and the vulcanization work can be facilitated.

[0012]

[Effect of device]

 The present invention has the following effects. That is, according to the level gauge of the present invention, it is possible to change the insertion lengths of the guide portion and the handle portion, respectively, without changing the inside of the case, the handle portion, and the mold, and measure the under-neck size and the neck. The dimensions can be changed, and parts can be shared for multi-specification level gauges with different under-neck and over-neck dimensions. Also, since the tubular body is inserted into the mold, the mold can be made simple and compact, and the vulcanization work can be facilitated.
