Description

[Detailed Description of the Invention] The present invention relates to a support device using tightening bolts used for attaching objects to be supported such as hoppers.

In the embodiment shown in FIGS. 1 and 2, the base plate 1 is constructed by cutting an elastic metal plate into squares.
A tightening plate 3 is formed by cutting a 〓-shaped cut 2 on the periphery 1' of this base plate 1, and a portion between the both incisal edges of the horizontal portion 2'' in the 〓-shaped cut 2 is formed. The clamping notches 5, 5' of the support 4, such as a hopper, are provided oppositely to each other, and the vertical part of the same shape notch 2 is provided on one side of the incisal surface of the horizontal part 2' of the shape cut 2. 2", insert a screw hole 9 at a location close to 1' so that the outer edge is
At the same time, a screw hole 6 is formed in a position corresponding to the inner end of the screw hole 9 on the other incisal surface of the horizontal portion 2' in the shaped cut 2.
is drilled so as to communicate with the same screw through hole 9,
A tightening bolt 7 is inserted into the screw hole 9 from the outside, and the tip of the tightening bolt 7 is screwed into the screw hole 6, and a large number of bolts are fixed to a location other than the tightening plate 3 on the base plate 1. The base plate 1 is screwed to other members (not shown) such as the fuselage using these mounting holes 8.

Further, the embodiments shown in FIGS. 3 and 4 are of a type that supports two and four objects to be supported.

The present invention includes a base plate 1 made of a hard plate such as an elastic metal plate or a plastic plate, and a fastener formed by cutting a square-shaped cut 2 in the periphery 1' of the base plate 1. The attached plate 3, the clamping notches 5, 5' of the supported object 4, which are provided oppositely at the middle of both incisal edges of the horizontal portion 2' in the shape cut 2, and the cutouts 5, 5' in the shape cut 2. A screw hole is drilled at a location close to the vertical portion 2'' of the same-shaped cut 2 on one side incisal surface of the horizontal portion 2' with the outer end opening into the end surface of the above-mentioned peripheral portion 1'. The hole 9 is bored in the other incisal surface of the horizontal portion 2' of the shaped cut 2 at a location corresponding to the inner end of the screw hole 9 so as to communicate with the same screw hole 9. It has a screw hole 6 and a tightening bolt 7 which is inserted into the screw hole 9 from the outside and whose tip is screwed into the screw hole 6. The support part of the hopper support 4 is inserted and the tightening bolt 7 is tightened, so that the free end of the tightening plate 3 is tilted in the direction of narrowing the width of the horizontal part 2' in the shape cut 2. The cut surfaces of the clamping notches 5, 5' are strongly pressed against both sides of the support part of the support 4 to fix the support 4 such as a hopper in an upright state, and when removing the support 4 such as a hopper, Tightening bolt 7
When loosened, the free end of the clamping plate 3
The width of the horizontal part 2' in the shape notch 2 is widened by its own elastic force, and the cut surfaces of the clamping notches 5, 5' strongly press both sides of the support part of the support 4. Release the pressure and then remove the support 4.
Of course, it has the advantage that the support 4 can be easily attached and detached. As long as it does not impair the elastic force of the clamping plate 3, it is possible to provide up to a large number of them as needed, so when it is attached to other parts such as the fuselage, supports 4 such as hoppers can be used. The number of mounting holes 8 can be freely increased when it is desired to improve the stability of the entire structure, which is advantageous in ensuring the stability of the entire structure. It is formed by cutting a square-shaped notch 2 in the periphery 1' of the base plate 1, and is not fixed to other parts such as the fuselage, so that the support 4 such as the hopper can be attached or removed by attaching the base plate 1 to the fuselage or other parts. It has the convenience of being fixed to the member, and furthermore, when the tightening bolt 7 is removed, that is, when the tightening plate 3 is in a free state, for example, between the clamping notches 5 and 5' is a support. It is possible to make the support part slightly smaller than the support part 4, and in this case, the horizontal part 2' of the notch 2 is scooped out with a tool such as a screwdriver to form the clamping notches 5, 5. Forcibly make the gap larger than the support part of the support 4, and in this larger state insert the support part of the support 4 into the gap between the clamping notches 5 and 5', eliminating the need for gouging with a tool such as a screwdriver. However, in this case, the support 4 is held in a temporarily fixed state by the elastic force of the tightening plate 3, which not only has the advantage of making it extremely easy to attach and detach the tightening bolt 7, but also has the above-mentioned advantages. As described above, since the opening operation can be performed using a tool such as a screwdriver, even if the support 4 is difficult to remove due to rust, etc., it can be easily removed during repair or the like. This has practical effects.
