Description

The present invention relates to an oil level gauge mounting structure used for measuring the amount of oil (liquid level) in the field of using oil such as an engine or a mission.

  Conventionally, as shown in FIG. 3, an oil level gauge 51 is known which is composed of a combination of a gauge plate 52 and a handle portion 53, and has a structure in which both 52 and 53 are connected by a rivet 54. The former gauge plate 52 is provided with a measuring part (not shown) for measuring the amount of oil, and the latter handle part 53 is provided with an opening of a pipe into which the oil level gauge 51 is inserted. A seal rubber 55 for sealing is provided.

  As the gauge plate 52, since the pipe into which the oil level gauge 51 is inserted has a twisted shape, a plate-like metal rod that is easily deformed corresponding to this is used.

  On the other hand, as the handle portion 53, a metal rod such as a round bar having high rigidity is used because the operator is a handle for attaching / detaching the oil level gauge 51. In particular, at the time of removal, since the seal rubber 55 is fitted into a tight tube, it is necessary to increase the rigidity in order to pull it out with a strong force. Further, for the purpose of facilitating gripping by the operator, as shown in the figure, the end portion 53a is devised such as being bent into a ring shape, and it is further identified that the portion is a portion that the operator holds. For this purpose, the handle portion 53 is painted on the surface of the metal bar, for example, red.

  When the conventional oil level gauge 51 is used at a location where the internal pressure is high, such as a turbo specification car, the oil level gauge 51 may be pushed by the internal pressure and come off the pipe. In view of this, a measure for preventing the oil level gauge 51 from being provided with a clip and hooking the clip onto the seal rubber 55 of the oil level gauge 51 is considered. not enough.

  Further, in the conventional oil level gauge 51, since the gauge plate 52 and the handle portion 53 are required to have different functions, it is necessary to use two types of metal rods, and further, these two types of metal rods are rivets. Since they are connected by 54, there is a disadvantage that the number of parts is large and the number of manufacturing steps is also large. In addition, the coating process for identifying parts is also a factor of high cost.

Further, since the other end portion 21b of the gauge plate 21 embedded in the rubber member 11 is disposed so as to overlap from the seal portion 13 through the umbrella portion 14 to the concave portion 17 of the handle portion 12, this gauge plate The other end portion 21b of the handle 21 can reinforce the handle portion 12, thereby ensuring the strength required for the handle portion 12. An operator who grips the handle portion 12 in the recess 17 simultaneously grips the other end portion 21b of the gauge plate 21 arranged inside the recess 17, and simultaneously grips not only the rubber but also the metal rod. Thus, the strength of the handle portion 12 can be increased and the handleability or operability of the oil level gauge 1 can be improved. Therefore, from the above, it is possible to provide the oil level gauge 1 that sufficiently satisfies the required functions while reducing the number of parts and the number of manufacturing steps.

  In addition, an umbrella part 14 is integrally provided between the handle part 12 and the seal part 13, and the umbrella part 14 covers the seal part 13 from above, so that external foreign matters such as muddy water and dust are applied to the seal part 13. Intrusion can be prevented.

  Moreover, since the recessed part 17 is provided in the outer peripheral surface of the handle part 12 and a finger can be engaged with this recessed part 17, it will become easy to grasp the handle part 12 as an operator.

  Furthermore, since the rubber member 11 is formed as a colored molded product, the rubber member 11 does not need to be subjected to a coating process in a subsequent process. Therefore, the painting process of the handle part 12 regarding the identification of the components can be omitted.
