Description

[Detailed description of the device]

[0001]

[Industrial applications]

 In the present invention, when a member is attached to a member mounting frame (hereinafter simply referred to as “frame”) having a T-shaped long groove with a cross section T, the member is mounted on the surface of the frame by using a special bolt, The present invention relates to a fixing device for fixing members.

[0002]

[Prior Art]

 As shown in FIG. 4, when the other member 2 is attached to the frame 1 made of aluminum, which is one of the constituent mechanisms of a mechanical device such as a belt conveyor, a straight line is formed from one end of the frame 1 to the surface of the frame 1. A long groove (hereinafter simply referred to as “long groove”) 4 having a T-shaped cross section is formed so that the slit 3 is opened, and the nut 5 is inserted into the long groove 4 by rolling or sliding it in advance. , The member 2 is fastened and fixed with bolts 6 from the outside.

[0003]

[Problems to be solved by the device]

 However, in such a fixing structure of the member 2, once the frame 1 is assembled, it is often impossible to insert the nut 5 into the long groove 4 from the one end of the frame 1, and an additional nut is inserted. In order to do so, it may be necessary to partially disassemble the assembled frame 1. The present invention has devised a structure in which the additional member 2 can be easily attached by using a special bolt without disassembling the frame 1 or the like that is once assembled.

[0004]

[Means for Solving the Problems]

 Therefore, the present invention is directed to a rectangular flat head having a short side slightly shorter than the width dimension of the slit 3 of the T-shaped long groove 4 and a long side longer than the T-shaped width dimension. And a special bolt having a round bar threaded portion having a diameter equal to or smaller than the dimension of the short side at the center of the head and perpendicular to the surface, an additional member 2 Was attached to solve the above-mentioned drawbacks.

[0005]

[Action]

 Therefore, even if the frame is assembled once, the additional member can be attached without disassembling.

[0006]

【Example】

 An embodiment of this invention will be described below with reference to the drawings. 1 is a perspective view of a member mounting device according to an embodiment of the present invention, FIG. 2 is a special bolt used in the present invention, FIG. A is a plan view, FIG. 2B is a side view, and FIG. FIG. 3 is a plan view of a special bolt of another embodiment which can be used in the present invention. The same reference numerals are given to the same technology and structure as those of the conventional member mounting apparatus shown in FIG.

First, a member mounting device and a special bolt used therein according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2. In this invention, a bolt, not a nut, is inserted into the long groove 4, and the special bolt 10 has a special structure as shown in FIG. That is, the special bolt 10 is composed of a head portion 11 and a round bar screw portion 12 formed perpendicularly to the surface of the head portion 11. The head 11 has a parallelogram shape, the short side of which is A, the longest dimension of which is B, the shortest dimension of which is C, and the width of the slit 3 of the long groove 4 is D. When the width is E, the depth is F, and the diameter of the round bar screw portion 12 is G, the following relationship is satisfied. That is, A ≧ GA <D B ≧ E and B ≧ E ≧ C ≧ D are satisfied. The thickness of the head portion 11 is smaller than the depth F of the long groove 4. And, as a matter of course, the end of the round bar screw portion 12 is spirally threaded.

In order to attach the member 2 to the frame 1 with such a special bolt 10, first, as shown in FIG. 1, the head portion 11 of the special bolt 10 is passed through the slit 3 of the frame 1 in the direction of the arrow Y to form a long groove. 4 and then, although not shown, the member 2 can be fixed to the surface of the frame 1 by inserting the member 2 into the round bar screw portion 12 and then tightening the nut. . When tightening with the nut, the head portion 11 tries to rotate in the clockwise direction of the arrow Z, but due to the dimensional relationship of B ≧ E ≧ C, the corners 13 and 14 of the head portion 11 contact the upper surface and the lower surface of the long groove 4, respectively. Then, the rotation of the special bolt 10 is blocked. Further, in this state, the head portion 11 of the special bolt 10 is caught on the inner wall of the frame 1, so that the special bolt 10 does not come off through the slit 3.

Further, the reason why the corners 13 and 14 are made obtuse is that care is taken not to damage the upper surface and the lower surface of the long groove 4 at the corners 13 and 14. When the frame 1 is made of an aluminum material, the material is soft, so the head portion 11 of the special bolt 10 should be formed in such a shape. However, it may have a rectangular shape with four corners rounded as shown in FIG.

[0010]

[Effect of the device]

 As described above, the member mounting device of the present invention can be easily mounted without disassembling the mounting member having the long groove 4 such as the frame 1 even when it is desired to additionally mount a member. The excellent effect is that the installation work can be done easily even in a narrow space.
