Description

[Detailed Description of the Invention] [Field of the Invention] The present invention relates to a fixture that can arbitrarily change the mounting direction of an electronic switch such as a proximity switch or a photoelectric switch configured as a housing.

[Summary of the idea]

The electronic switch mount according to the present invention has a protrusion with a claw and a locking piece that engages the claw, and the electronic switch is mounted using two clamp members of the same shape each having a groove into which the protrusion is inserted. By fitting with the lead-out tube, the clamp member and the electronic switch body are integrated, and even when the electronic switch body is rotated to change the detection surface, the electronic switch body can be slid without separating the clamp member. It was designed so that

[Prior art and its problems]

Proximity switches and photoelectric switches configured as a housing have a sensing surface on the front or side surface of the housing, but they are attached in one direction, making it impossible to freely change the direction of the sensing surface. However, when the sensing surface is provided on the side surface, it is highly necessary to change the sensing direction, and therefore it is necessary to attach the housing to the mounting base using a rotatable fixture.

By the way, in conventional rotatable electronic switches, the fixture is made up of two or four members, and when rotating the housing to change the detection direction, they must be disassembled and assembled in a predetermined direction before installation. It needed to be fixed. Therefore, there is a problem that the members of the fixture may be scattered, and it takes a lot of effort to change the direction.

[Purpose of invention]

The present invention was developed in view of the problems with the conventional electronic switch fixtures, and allows the detection direction of the electronic switch to be easily changed when the housing is rotated without having to separate the fixtures. We propose an electronic switch mount.

[Structure and effect of the idea]

The present invention is an electronic switch fixture that surrounds and fixes the lead-out tube of an electronic switch with a pair of clamp members having symmetrical arc-shaped notches, and includes a protrusion having a claw at the tip, and a protrusion that engages the claw. Two clamp members are provided, each having a groove at one end thereof, each having a locking piece for locking the protrusion into which the protrusion is inserted. A locking position where the ejection cylinder of the electronic switch is fitted into the groove and can be rotated freely by the locking piece and the claw when one clamp member is pulled out, and a fixed position where the ejection cylinder of the electronic switch is fixed when the clamp member is pushed in. It is characterized by being slidably fitted between the two.

According to the present invention having such features, if the lead-out tube is sandwiched and engaged between a pair of clamp members having the same shape, these clamp members are always connected to the main body of the device without being separated. They will be fitted. When rotating the detection surface of the device body, the detection surface can be directed to any desired position by loosening the engagement of the clamp member within a predetermined range, rotating the device body, and then fixing the clamp member again. It becomes possible. Furthermore, in the present invention, since two identical clamp members are used to sandwich the lead-out tube, the clamp members can be manufactured easily. Furthermore, since the clamp member is formed integrally with the main body of the device, there is no fear that it will come off, making it possible to provide an easy-to-use electronic switch mount.

[Explanation of Examples]

FIG. 1 is a perspective view of an electronic switch mount according to the present invention, and FIGS. 2a and 2b are a side view and a sectional view of the main body of the device. As shown in these figures, the electronic switch has a main body 1 formed as a casing, and has a detection surface 1a on one side thereof, for example, the top surface in the state shown in FIG. A mounting portion 2 is provided on the back side of the device main body 1 along its axis. The mounting portion 2 has a lead-out tube 3 connected to the device body 1 and a conduit ring 5 having a conduit hole 4 in the center. The lead-out tube 3 is formed into a cylindrical shape, and has linear grooves 6 in the center in four directions parallel to the four sides of the back surface of the device body 1, and a cylinder that curves and protrudes at the four corners except for these grooves. Curved protrusions 7a-7 parallel to the axis

The device main body 1 thus formed has clamp members 10, 1 formed in the same shape at the position of the mounting portion 2.
Installed by 1. As shown in FIGS. 1 and 3, the clamp member 10 has a substantially semicircular notch in its lower surface, and the notch has symmetrical holes along the axis as shown in FIGS. 1 and 3b. two curved grooves 1
2a and 12b are provided, and the clamp member 11 is provided with curved grooves 13a and 13b at the same position. The clamp members 10 and 11 are provided with screw holes 14a, 14b, 15a and 15b through which bolts for fixing the clamp members are passed from the upper surface. The curved groove side of the screw holes 14a and 15a has an outward claw 1 as shown in FIGS. 1 and 3b.
6 and 17, respectively, and recesses 20 and 21 are provided on the curved groove sides of the screw holes 14b and 15b, respectively, in the direction of the side walls of the clamp members 10 and 11 as shown in the figure. The claws 17, 16 of the other clamp member 11, 10 are attached to the tip of the clamp member 11, 10.
Locking claws 22 and 23 are provided for locking.

The clamp members 10 and 11 thus formed are assembled to the mounting portion 2 of the device main body 1. That is, since the semicircular notches of the clamp members 10 and 11 are formed in the same shape, when they are combined, a substantially elliptical through hole is formed, into which the lead-out cylinder 3 of the mounting portion 2 is fitted. At that time, the clamp member 10
and 11, respectively, to the recesses 21, 20 beyond the locking claws 23, 22 of the other clamp member.
By inserting the clamp member 10,1 into
1 cannot be separated, and the side surfaces of the protrusions 18 and 19 abut against the inner surfaces of the recesses 21 and 20 of the clamp members 10 and 11, and are slidably fitted at a minute interval. As shown in FIG. 5, the curved protrusions 7a~
7d to the curved grooves 12a of the clamp members 10, 11,
12b, 13a, and 13b, push the clamp member 10 toward the 11 side, and screw the screw holes 14a,
Bolts are passed through 14b, 15a, and 15b to connect them to a base (not shown). At this time, as shown in FIG. 1, since the lead-out cylinder 3 is provided with a groove 6, the bolt does not come into contact with the lead-out cylinder 3, and the mounting part 2 is tightened and fixed at the fixed position of the clamp members 10 and 11. Ru. In this way, the main body 1 of the electronic switch can be fixed in the haze.

When rotating the main body 1 to direct the detection surface 1a in the other direction, a bolt (not shown) is loosened and one clamp member, for example 10, is pulled upward. Then, the clamp member 10 is pulled out to the locking position where the claws 16 and 17 of the projections 18 and 19 abut against the locking claws 22 and 23, respectively. Therefore, the through holes formed by the notches of the clamp members 10 and 11 are expanded, and the device body 1
