Technical Field

The present invention relates to a sensor fixing device, and more particularly, to a sensor fixing device to be mounted on a program system component.

Background

A conventional sensor fixing device will be described with reference to the operation detection device 2 shown in fig. 8. The operation detection device 2 includes: a sensor 3 for detecting an operating state, which is in contact with an inlet 1 of a vapor trap as a detected part; a holding member 4 which is connected with the sensor 3 for detecting the operation state, is provided with a pair of insertion holes and is positioned on one side of the inlet 1 of the steam trap; a clamping member 5 which is positioned on the opposite surface of the inlet 1 of the steam trap, has an upper wall and two side walls, and has a section of approximately コ characters, wherein the upper wall is provided with a pair of insertion holes, a plane part contacted with the plane part of the prism of the detected part is formed between the pair of insertion holes, and two side walls are provided with groove parts with an approximately く character shape, which are contacted with the two sides of the curved surface part of the cylinder of the detected part; a U-bolt 6 having both legs 6a inserted into the pair of insertion holes of the clamping member 5 and the pair of insertion holes of the holding member 4; and a pair of nuts 7 attached to both legs 6a of the U-bolt 6. (see patent document 1 above).

Disclosure of Invention

Problems to be solved by the invention

The operation detection device 2 described above has a problem to be improved as described below. In the motion detection device 2, the holding member 4, the clamping member 5, the U-bolt 6, and the pair of nuts 7 are formed as independent workpieces. Therefore, there is a problem to be solved that the nut 7 may be dropped from the hand and lost when the members are assembled and mounted. In particular, the installation space of the program system constituting device is often limited, and the program system constituting device may be heated to a high temperature, thereby losing the nut 7.

Accordingly, an object of the present invention is to provide a sensor fixing device capable of preventing the loss of a mounting nut.

ADVANTAGEOUS EFFECTS OF INVENTION

Means for solving the problems of the present invention and effects of the present invention are shown below.

The sensor fixing device of the present invention is a sensor fixing device that is mounted to a mounting portion formed in a program system component along a predetermined mounting axis, the sensor fixing device including: a main body portion which is disposed along an outer edge of the mounting portion, has a1 st opening at one end portion and a 2 nd opening at the other end portion, and into which a mounting bolt is inserted, the mounting bolt being inserted into the 1 st opening and the 2 nd opening of the main body portion, and being inserted in a direction intersecting the mounting shaft in a mounted state in which the main body portion is disposed along the outer edge of the mounting portion; and a mounting nut that mounts the mounting bolt to the body portion, the mounting nut being rotatably held by the body portion so as to be threadably engaged with the mounting bolt.

Thereby, the mounting nut is held as one body with the body portion. Therefore, it is possible to prevent the loss of only the mounting nut, such as dropping at the time of mounting.

In the sensor fixing device according to the present invention, the mounting nut is rotatable in a direction intersecting a direction in which the mounting bolt is inserted.

Accordingly, the mounting nut can be disposed perpendicularly to the mounting bolt regardless of the disposition angle of the body portion, and therefore, the mounting bolt and the mounting nut can be easily screwed together.

In the sensor fixing device according to the present invention, the main body has a1 st side wall and a 2 nd side wall at the other end portion, the 1 st side wall and the 2 nd side wall being disposed perpendicularly to the mounting shaft and facing each other in the mounted state, the 1 st side wall has a predetermined 1 st side wall opening, the 2 nd side wall has a predetermined 2 nd side wall opening, and the mounting nut has a spherical portion which is disposed between the 1 st side wall and the 2 nd side wall, has a diameter longer than a distance between the 1 st side wall and the 2 nd side wall, and engages with the 1 st side wall opening and the 2 nd side wall opening.

Thereby, the mounting nut is held as one body with the body portion. Therefore, it is possible to prevent the loss of only the mounting nut, such as dropping at the time of mounting. Further, the mounting nut can be disposed perpendicularly to the mounting bolt regardless of the disposition angle of the body portion, and therefore, the mounting bolt and the mounting nut can be easily screwed together.
