[0003]

In the example described in the prior art, if a device with a long depth is fixed near the left and right of this mounting device, there is not much working space and it is difficult to mount the metal fittings. , When the fixing shaft was strongly tightened to firmly fix the mounting device to the panel, the convex part of the metal fitting sometimes destroyed the hole of the mounting device.

An object of the present invention is to make the work easy even if there is not much work space near the mounting equipment, and
It is to provide a panel mounting device that does not break even if the tightening torque when fixed is excessive.

[0005]

In order to achieve the above-mentioned object, the invention described in claim 1 is such that the flange of the mounting device inserted through the opening of the panel abuts against the front surface of the panel and is integrated with the mounting device. In a device that is fixed to the panel by being attached to the panel and being attached to the panel by the front end of the fixture that moves forward and backward by tightening the screw from the rear of the panel, the fixture is inclined outward toward the front of the device. And a straight part that fits in the groove of the housing, and a metal fitting that supports the mounting device and the screw hole of the mounting device and the screw thread fit together, and the screw that moves the bracket from the rear to the front-back direction of the device. The mounting device includes an oblique groove that is inclined outward toward the front and fits with a part of the metal fitting, and a groove that fits with a straight part of the metal fitting. Only, characterized in that a metal screw holes for screws that are integrally molded is provided in the device.

According to a second aspect of the present invention, the flange of the mounting device inserted through the opening of the panel is in contact with the front surface of the panel, is integrally mounted to the mounting device, and is screwed from the rear of the panel. In the device fixed to the panel by the front end of the mounting device that can move back and forth by contacting the back surface of the panel, the mounting device includes a portion that inclines outward toward the front of the mounting device and a linear portion in which a long hole is formed. And a metal fitting for supporting the mounting equipment and a screw for moving the metal fitting in the front-back direction of the equipment by fitting the screw hole of the mounting equipment with the screw thread.
The mounting device includes a slanting portion that tilts outward toward the front and guides a part of the metal fitting, a drop prevention portion that enters a long hole of the metal fitting, and a metal for a screw integrally molded in the housing. And a screw making hole.

Furthermore, the invention described in claim 3 is the apparatus according to claim 1 or 2, wherein the attachment is provided with a spring for applying a force in the direction of unscrewing. .

[0008]

According to the present invention, the mounting device is provided with two kinds of grooves which allow the mounting device to move outward when guided and pushed into the mounting device, and the screw holes for screws for pushing the mounting device from the rear are made of metal. Therefore, before tightening the screw, the mounting tool becomes almost integrated with the mounting device, the screw can be tightened from the rear of the mounting device, and the mounting tool advances to the panel surface, and the metal screw hole is not broken.

Further, according to the present invention, the mounting device is provided with a shape such that the mounting device can move outwardly when guided and pushed into the mounting device, and the fastener and the long hole are provided so as not to separate the mounting device from the mounting device. Since the screw hole for the screw that pushes the mounting tool from the rear is made of metal, the screw can be tightened from the rear of the mounting device,
Moreover, the fixture advances to the panel surface, and the metal screw hole is not broken.

Further, according to the present invention, since a spring for exerting a force in the direction in which the screw is pulled out is provided at the rear part of the fitting to press the fitting before fixing in one direction, the fitting is almost integrated without separating from the fitting device. Can be converted.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a state in which a mounting device is fixed to a panel in an embodiment of the present invention. When the screw 3 of the mounting device 1 is loosened, as shown in FIG. 2, the mounting device 2 moves backward and becomes the same as the outer periphery of the mounting device 1. Therefore, in this state, the mounting device 1 is mounted from the front of the panel 21 to the mounting hole 21a. Then, when the screw 3 is tightened from the rear part, the fixture 2 is moved in the Y direction by the guide portion 2g to come into contact with the back surface of the panel 21, and the equipment flange 1a is pressed against the panel 21 to be fixed.

FIG. 2 is a view for explaining the mounting tool 2 of FIG. 1 and related parts thereof. The mounting tool 2 with a guide portion 2g that fits into the oblique groove 1g of the case 1 has a screw 3 and a metal screw portion 1n.
The attachment 2 is pressed against the rear surface of the rear long hole by the washer 4 and the compressible spring 5 in the rearward direction. When the screw 3 is loosened, the size is the same as that of the outer circumference of the case 1 in a state where the rear part is projected like the mounting tool 2 at the lower right.

FIG. 3 shows another embodiment of the present invention, which is a case 6
In the same manner as in FIG. 2, a guide portion 6g having only an inclination is provided on the case 6, and the fixture 7 with the guide portion 7g is attached to the case 6 with a screw 3, a washer 4, a spring 5, and a metal screw portion 6n, and a fastener 8 is attached. It is put in the long hole 7h and fixed to the case 6 by the fastener 8a.
As shown in the figure, the fastener 8 does not hinder the forward and backward movement of the attachment 7 and has a function of preventing falling. Inserted into the panel hole at the lower right of this figure, and tightening the screw 3 will always push the mounting member 7 backward by the spring 5.
The mounting device 6 can be fixed to the panel in the same manner as in FIG.

1 and 3, the inclined portion is provided in the horizontal direction to open the mounting tool in the horizontal direction.
Obviously, the same effect can be obtained by providing the inclined portion in the vertical direction.

[0015]

According to the present invention, the mounting tool is substantially integrated with the case, the mounting device is put in the panel hole, and the screw that engages with the metal screw hole is rotated from the rear to move the mounting tool forward. Since the mounting device is fixed to the panel by tightening it, the mounting device can be easily tightened and removed even if there is not much working space, and the mounting device can be provided without causing damage due to screw tightening. In addition, since the fitting is pushed backward by the spring, it is possible to provide the fitting device in which the fitting is stably mounted on the case.
