Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a rail mounting mechanism, and more particularly to a mechanism for mounting a sensor on a rail.

[0002]

[Prior Art]

 This type of rail mounting mechanism that has been conventionally used will be described with reference to FIGS. 10 to 12. The rails used in the conventional example and the embodiment of the present invention are usually those conforming to the DIN standard, but it is not always necessary to adhere to this standard. First, as shown in FIG. 10, the projecting piece 21 of the movable member 20 having the wavy spring 24 attached to the body 19 by the pin 23, and the projecting piece provided on the other side of the body 19 facing the projecting piece 21. The rail 25 is attached between the rails 26 and 26. Further, when removing the rail 25, the knob 22 of the movable member 20 is moved in the direction of the arrow (FIG. 12).

[0003]

[Problems to be solved by the device]

 In the rail mounting mechanism of the conventional example, since the small knob 22 is pulled and moved to remove the rail 25, there is a problem that the operation is not easy.

[0004]

[Means for Solving the Problems]

 The present invention eliminates the defects of the conventional example, and opens a structure in which the rail can be easily attached and detached. The structure will be described below with reference to the drawings of the embodiments. The rail locking portion 2 having the projection 2a facing the bottom groove 9 is connected to a pair of openable and closable knobs 4 and 4 pivotally mounted on the main body 1 via an elastic bending arm 5, and the pair of knobs 4 and 4 are connected. , 4 are opened and closed to expand and contract the elastic bending arm 5, thereby displacing the protrusion 2a of the rail engaging portion 2 and allowing the rail 18 to be detachably attached to the bottom surface groove 9 of the main body 1. , A stopper 7 is provided in the middle of the pair of knobs 4 and 4, and a knob 11 provided with anti-slip is provided on the outer circumference of the knobs 4 and 4, or the rail locking portion 2 is attached to the elastic bending arm 5 by the pin 3a. The pair of knobs 4 and 4 are pivotally attached to the main body by pins 3b and 3b, respectively, and a pawl 6 is formed on the outer circumference of the pair of knobs 4 and 4, and a stopper 14 for locking the pawl 6 is attached to the main body 1. It has a structure provided on one side.

[0005]

[Action]

 By pressing the knobs 4 from both sides to disengage the pawls 6 from the stoppers 14 and move the rail engaging portion 2 together with the protrusion 2a to the side opposite to the side where the rails 18 are attached, the rails 18 can be very easily and very easily. It is possible to attach the rail 18 to the main body very easily by removing the rail from the attachment main body 1 and performing the reverse operation to the above.

[0006]

【Example】

 An embodiment of a mounting mechanism according to the present invention will be described below with reference to the accompanying drawings. 1 to 3, the mounting portion main body 1 is made of hard plastic or the like. Reference numeral 9 is a groove forming the bottom surface of the main body 1, and reference numeral 2 is a locking portion provided on the main body 1 on one side of the bottom surface groove 9 and has a projection 2a. A protrusion 8 is provided on one side of the bottom groove 9 so as to face the protrusion 2a. Reference numeral 3a is a pin for attaching the locking portion 2 to the main body 1, and 4 is a pair of knobs pivotally mounted on the main body 1 by the pins 3b, 3b, and a pawl 6 is formed at the outer edge of the knob 4. 5 is an elastic bending arm that connects the locking portion 2 and the knob 4, 7 is a stopper located at the end of the main body 1 and provided between the knobs 4 and 4, and 11 is an outer end of the knob 4. Numeral 10 is a saw-shaped slip stopper formed on the knob 11. As shown in FIG. 5, mounting legs 12 are formed on both sides of the main body 1, and a sensor portion 17 is mounted between the legs 12. Further, in FIG. 4, reference numeral 13 is a groove portion for assembling the projection 2, and reference numeral 14 is a stopper which forms the outer edge of the groove portion 13 and which stops the pawl 6. Further, reference numeral 15 is a hole for inserting and locking the pins 3b, 3b for pivotally attaching the knobs 4, 4 to the main body 1, and 16 is a hole for inserting the pin 3a for attaching the locking portion 2 to the main body 1.

Next, the operation of attaching / detaching the rail 18 to / from the rail mounting mechanism will be described. First, as shown in FIG. 5, the sensor 17 is attached to the inside of the mounting leg 12 by pushing down the sensor 17 from above. Next, when attaching the rail 18 to the main body 1, the main body 1 with the sensor 17 assembled is kept at a position inclined to one side, and one end of the horizontally arranged rail 18 is locked by the projection 8 on one side of the rail 18. Then, when a force is applied to the sensor 17 in the direction of the arrow, the projection 2a of the locking portion 2 is pressed against the elasticity of the elastic bending arm 5 and moves leftward toward FIG. When a further force is applied, the locking portion 2 returns to its original position due to the elastic repulsive force of the elastic bending arm 5, so that the rail 18 is locked by the projection 2a so as not to fall out, and the rail 18 is inserted into the bottom groove 9 of the main body 1. 18 is fixed. Next, the operation of removing the rail 18 from the main body 1 will be described. As shown in FIG. 7, when the knob 11 provided with the anti-slip 10 is pushed to apply a force to both sides of the knobs 4 and 4, the tab 6 on the outer edge of the knob is disengaged from the stopper 14 (FIG. 8). 9, the rail 18 can be easily removed from the mounting portion main body 1 by moving in the arrow direction as shown in FIG. 9 while applying the pressing force. At this time, since the stopper 7 is interposed between the knobs 4 and 4, the stoppers 7 can be held at appropriate intervals without applying an extra force to the knobs 4 and 4, so that the rail 18 can be easily removed from the main body 1. The slip stoppers 10 and the knobs 11 are useful for pressing the knob 4 and facilitating the operation of moving it.

[0008]

【effect】

 In the present invention, the elastic bending arm is actuated by opening and closing the gap between the pair of knobs to displace the locking portion having the protrusion, thereby facilitating the work of attaching and detaching the rail to the mounting portion main body. There are effects such as being able to.
