Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention mainly relates to a mounting base for mounting a small proximity switch or the like at a desired location.

<Conventional technology> Conventional mounting bases used for such applications include:
The one shown in FIG. 9 or 10 is common. That is, in the one shown in FIG. 9, the holding part 1 of the proximity switch S is formed by curving the central part of a single rectangular metal plate into a substantially circular cross section, and the mounting plate parts 2 on both sides of the overlapping parts are screwed. By inserting the proximity switch S into the holding part 1 and screwing the screw 4 inserted into the screw hole 3 into the mounting point and tightening it, both mounting plate parts 2 can be attached to each other. The proximity switch 1 is fixed by the holding part 1 after being joined.

On the other hand, the one in FIG. 10 has a holding part 5 and a mounting part 6.
It has an L-shaped cross section with the and
The mounting hole 7 of the holding part 5 is deformed by a movable fixture 8, and this fixture 8 has mounting screws 8b, 8 in holes 8a, 8a formed on the top surface.
b is provided, and after inserting the proximity switch, tighten the mounting screws 8b, 8b to fix the fixture 8, and then insert the screw into the screw hole 9 drilled in the mounting part 6. It is designed to be fixed at the installation location.

(Problems to be Solved by the Invention) Incidentally, all of the above-mentioned mounting bases are configured to fix the proximity switch S in a state parallel to the mounting location. However, in recent years, it has become increasingly necessary to mount the small proximity switch S by penetrating it from a right angle to the mounting location. The mount shown in FIG. 9 is completely incompatible with this type of mounting. In addition, in order to use the one in Fig. 10 for the above-mentioned mounting form, as shown by the dashed line in the same figure, the holding part 5
It is necessary to newly drill a hole in the hole, which requires extra work, but it also has the disadvantage of being unsightly and incompletely installed.Furthermore, in such a case, the mounting part 6 becomes unnecessary, making it uneconomical. be.

(Purpose of the invention) The present invention was devised in view of the above-mentioned problems, and provides a proximity switch, etc., which can be selectively positioned in two orthogonal directions without any processing. The purpose is to provide a mounting base for the.

(Means for Solving the Problems) In order to achieve the above-mentioned purpose, the mounting base for the proximity switch, etc. of the present invention has a mounting base in which the proximity switch, etc. is inserted and fixed, and is fixed to the mounting location with screws. It consists of a pair of base bodies of the same shape whose outer shape becomes a rectangular parallelepiped by joining them facing each other.The joint surfaces of these base bodies, which are assembled in a staggered manner, are approximately Z when viewed from the side. It has a shape in which a cylindrical body is divided into two parts, each having a triangular guide protrusion protruding from opposing surfaces so as to form a rectangular parallelepiped and an insertion hole penetrating from one side to the other. a guide groove body constituting the insertion hole, which has a hole area that can clamp and fix a proximity switch, etc. when combined; and a first guide groove body for screw insertion parallel to the insertion hole when both base bodies are combined into a rectangular parallelepiped.
When the two base bodies are combined into a rectangular parallelepiped, the semicircular portions of the two base bodies are combined to form a second mounting hole that passes through the first mounting hole in a direction perpendicular to the first mounting hole. The gist is a configuration in which a U-shaped groove is formed.

(Function) With the above configuration, in the rectangular parallelepiped formed by combining a pair of base bodies, the insertion hole for a proximity switch etc. is formed by the guide groove body of both base bodies, and the through hole of each base body Thus, a first mounting hole for screw insertion is formed parallel to the insertion hole, and a second mounting hole is formed in a direction perpendicular to the first mounting hole by the U-shaped groove of each base body. By selectively inserting screws into both of the mounting holes and mounting, a proximity switch or the like can be mounted in two directions orthogonal to the mounting location, that is, in both parallel and perpendicular directions. At this time, the pair of base bodies are assembled in a staggered manner, and each mounting hole is formed by each component of both base bodies, so that after inserting the proximity switch into the insertion hole, In the process of inserting a screw into the mounting hole, screwing it into the mounting location, and tightening, the triangular guide protrusions on each base body slide into contact with each other, so that both bases can be fixed in either of the two orthogonal directions. The element bodies are brought into close contact with each other smoothly, and thereby the insertion hole is deformed in a direction in which the diameter thereof is reduced, and the proximity switch inserted through the insertion hole is fixed so as not to be easily pulled out.

(Embodiment) Hereinafter, a preferred embodiment of the present invention will be described in detail based on the drawings.

In FIG. 1, the mounting base of the present invention is composed of a pair of base bodies 10 of the same shape, and by combining both base bodies 10 in an inconsistency manner,
As is clear from FIGS. 2, 3, and 4, which show the front, plane, and right side, respectively, it is a rectangular parallelepiped. When assembled into a rectangular parallelepiped, as shown in FIG. 2, an insertion hole 11 is formed in the center that penetrates from the front to the back in the front-rear direction, and parallel to each other on both sides of the insertion hole 11. A pair of first mounting holes 12 are formed, and further,
As shown in FIG. 3, a pair of parallel second mounting holes 13 are formed that penetrate from the plane to the bottom surface.

On the other hand, each base body 10, as shown in FIG.
The overall shape is a substantially Z-shaped cut along the cutting line between both side surfaces of a rectangular parallelepiped. As is clear from FIG. 1 and FIGS. 5 and 6, which show the front and plane views of each base body 10, a half-shaped rectangular cylinder body with an insertion hole 11 in the center is divided into two halves. A circular guide groove body 11a is protruded, and U-shaped grooves 13a are formed in parallel in the vertical direction on both sides of this semicircular guide groove body 11a, and in each U-shaped groove 13a, front and rear grooves perpendicular thereto are formed. A through hole 12a is perforated in each direction. Furthermore, a fitting hole 11b into which the inner end of the semicircular guide groove 11a is inserted is bored in the outer end surface of the semicircular guide groove 11a. Engagement protrusions 14 are provided on both sides of the lower part, and engagement protrusions 14 are provided on both ends of the upper part.
An engagement hole 15 into which the guides 4 fit is formed, and four guide protrusions 16 having a substantially right triangular shape are protruded inward at substantially equal intervals.

To explain the function of the embodiment mounting base having the above-mentioned structure, as shown in FIG.
0 is turned upside down so that it faces the other, and when they are joined together, the engaging protrusions 14 of each other fit into the engaging holes 14, respectively, as shown by the dashed line in the figure, and as shown in FIG. As shown, the sloped portions of the guide protrusions 16 are joined together. In other words, the two base bodies 10 are assembled in a staggered manner. At this time, as is clear from FIG. 2, the semicircular guide groove bodies 11a are butted against each other to form the insertion hole 11, and the tips of the semicircular guide groove bodies 11a are fitted into the fitting 11b. Thus, both semicircular guide groove bodies 11a face each other without shifting, and the insertion hole 11 is held. Similarly, the through holes 12a are connected in a line to form the first mounting hole 12, and the third mounting hole 12a is connected in a row.
As shown in the figure, the U-shaped grooves 13a are opposed to each other to form the second mounting hole 13.

As is clear from FIG. 4, in the rectangular parallelepiped state in which the two base bodies 10 are assembled in a staggered manner,
There are slight gaps A and B between the front and back directions and between the top and bottom of both base bodies 10, respectively. In this state, if the proximity switch S is inserted into the insertion hole 11 and the screw C of the first mounting hole 12 is inserted as shown in FIG. On the other hand, as shown in FIG. 8, the second mounting hole 1
3, the proximity switch S can be positioned parallel to the mounting location and fixed. In either case, by tightening the screw C at the mounting location, the slope portions of the guide protrusions 16 that are connected to each other slide against each other, so that both base bodies 10 come into close contact with each other, and each engaging protrusion Part 1
4 is completely inserted into the engagement hole 15, and gaps A and B disappear. Along with this, the insertion hole 11 is also deformed to reduce its diameter and is pressed into contact with the proximity switch S, so that the proximity switch S is held so that it will not come out.

(Effects of the invention) As detailed above, according to the mounting base for a proximity switch, etc. of the present invention, by combining a pair of base bodies of the same shape in a staggered manner to form a rectangular parallelepiped, a through hole for a proximity switch, etc. Since the mounting hole parallel to the mounting hole and the mounting hole orthogonal to the mounting hole are formed by the respective constituent members of both base bodies, it is possible to install the proximity switch etc. in the parallel direction and the orthogonal direction to the mounting point. Can be installed selectively. In addition, by combining the triangular guide protrusions of each of the pair of base bodies in an inconsistency manner, in the process of inserting the screw into the mounting hole, screwing it into the mounting location, and tightening, Due to the sliding contact of the triangular guide protrusions, both base bodies are brought into close contact with each other smoothly in both orthogonal directions, and the insertion hole is thereby deformed to reduce its hole area. It is possible to securely hold a switch, etc. without removing it. Furthermore, since both base bodies have the same shape, when molding them from synthetic resin, only one expensive molding die is required, resulting in a large economical effect.
