At this time, the connection bar 31 is inserted into the support groove 333 formed around the rotation body 33 to be appropriately supported while simultaneously reducing the degree of bending of the connection bar 31.

When the rotary body 33 is rotated by the bending of the lever 34, the fitting protrusion 32 is positioned below the support shaft 332 so that the horizontal movement of the connecting bar 31 is stopped. will be.

5 is a side sectional view showing a main portion enlarged part showing an operating state of the present invention;

Figure 5a is a side cross-sectional view showing a release state,

5B is a side cross-sectional view showing a fixed state.

The operating state of the present invention with reference to FIG. 5 is as follows.

As shown in FIG. 5A, when the fixing device is released from the rail 4, the rotating body 33 is bent in the clockwise direction by bending the lever 34 downward in the mounting groove 37. When rotated about), the fitting projection 32 is inserted into the insertion groove 331 of the rotating body 33 is to move the connection bar 31 to the outside.

When the connection bar 31 is moved to the outside in this way, the second hook 22 moves to the outside, and the bending bar 221 moves to the outside as the second hook 22 moves. The rotary link 23 coupled to the end of 221 is rotated counterclockwise about the rotation shaft 231 to push the sliding bar 211 outward.

As such, when the sliding bar 211 is pushed outward, the first hook 21 and the second hook 22 are opened to the outside while the first hook 21 is pushed outward and released from the rail 4. .

At this time, the spring 43 installed between the support jaw 42 toward the outside of the second hook 22 is in a pressurized state.

As shown in FIG. 5B, when the lever 34 is bent upward and inserted into the mounting groove 37 as opposed to the release process, the spring 43 is elastically restored while being released in the pressurized state. 221 is moved inward, and the second hook 22 is moved inward.

In this state, the rotary link 23 connected to the bending bar 221 moves clockwise around the rotational axis 231 according to the movement of the bending bar 221 to move the sliding bar 211 inward. Will be done.

As the sliding bar 211 moves inward, the first hook 21 moves inward, and as a whole, the first hook 21 and the second hook 22 move inward at the same time. The first hook 21 and the second hook 22 is firmly fixed to both sides of the.

At this time, the spring 43 is maintained in a pressurized state to some extent to increase the fixing force of the first hook 21 and the second hook 22 while at the same time buffering the vibration transmitted to the rail 4 from the industrial equipment to offset Will be done.

In addition, in the above state, the connecting bar 31 is bent upward to support the guide bar 311 through the flexible bar 312, so that the fixing force of the first hook 21 and the second hook 22 is increased. It doesn't change and stays on for a long time.

As described above, the present invention allows the module to be firmly fixed to the rail with a simple structure, so that the module can be easily attached to or detached from the rail, and then the binding is prevented, thereby preventing the module from twisting due to the vibration of the industrial equipment. It has the effect that a short circuit is appropriately prevented.

In addition, the present invention has the effect that the operation is formed in a simple structure to facilitate the operation of locking and unlocking, thereby significantly simplifying installation and assembly.
