[0047] The anti-impact fixing bolt structure of the application will be described in detail below through the following embodiments.

[0048] In the embodiment, as shown in Figure 1 And Figure 2 The anti-impact fixing bolt structure is applied to the connection of two flanges, comprising: a fixing bolt 2 provided with an end portion 201 and a threaded column portion 202, and penetrating the fixed object 1;

[0049] A first fixing member 3 is provided with a fixing hole, and the bottom surface of the fixing hole is provided as a first inclined surface;

[0050] A second fixing member 4 is provided with a first strip-shaped hole extending in a first direction, and the top surface of the first strip-shaped hole is provided with a second inclined surface, the second inclined surface is coplanarly arranged with the first inclined surface, and the second inclined surface gradually rises along the positive direction of the top surface of the first direction, and the bottom surface of the second fixing member 4 is attached to the fixed object 1;

[0051] A force spring 5 is connected with the first fixing member 3 and the second fixing member 4 respectively, for applying an action force in the reverse direction of the first direction to the first fixing member 3, and for applying an action force in the positive direction of the first direction to the second fixing member 4;

[0052] A fixing nut 6 is screwed on the threaded column portion 202, for pressing the fixed object 1 together with the fixing bolt 2;

[0053] A gasket 7 is sleeved on the threaded column portion 202, provided with a first segment portion 701 and a second segment portion 702, the first segment portion 701 is located at the first strip-shaped hole, and the second segment portion 702 is located between the first inclined surface and the second inclined surface.

[0054] In the technical solution, the fixed object 1 is vertically placed, and the through hole on the fixed object 1 is vertically arranged. The fixing bolt 2 and the fixing nut 6 are standard parts and can be purchased on the market. The first fixing part 3 is a horizontal downward L-shaped plate, the lower side of which is provided with a downward protruding cylindrical protrusion, the lower side of the cylindrical protrusion is provided with a first inclined surface, and the cylindrical protrusion is provided with a fixing hole at a corresponding position. The second fixing part 4 is a horizontal upward L-shaped plate, the upper side of which is provided with an upward protruding waist-shaped protrusion, the top surface of the waist-shaped protrusion is provided with a second inclined surface, the waist-shaped protrusion is provided with a first strip-shaped hole at a corresponding position, and the height of the waist-shaped protrusion gradually increases in the direction of the right side. The included angle between the first inclined surface and the second inclined surface and the horizontal plane is 10 to 20°, and the arrangement of the first inclined surface and the second inclined surface can avoid asynchronous rotation of the first fixing part 3 and the second fixing part 4, so that the vertical plane of the first fixing part 3 and the second fixing part 4 on the right side is always parallel, facilitating the fixation of the force spring 5.

[0055] The force spring 5 is a compression spring and is clamped between the first fixing part 3 and the second fixing part 4, or is fixed at two ends of the first fixing part 3 and the second fixing part 4 respectively. The first fixing part 3 is coaxially arranged with the fixing bolt 2, and the second fixing part 4 is slidably connected with the fixing bolt 2 through the first strip-shaped hole. The arrangement of the force spring 5 can automatically drive the second fixing part 4 to move to the right relative to the fixing bolt 2.

The arrangement of the gasket 7 reduces the hard friction between the first fixing part 3 and the second fixing part 4, and improves the ability of the vibration potential to transmit to the force spring 5 when the fixed object 1 vibrates.

[0057] When the fixed object 1 vibrates, the vibration tends to increase the distance between the end 201 of the fixing bolt 2 and the fixing nut 6, and this trend is absorbed by the gasket 7, the second fixing part 4 and the force spring when passing through the first fixing part 3 and the second fixing part 4, thereby ensuring the fixing effect between the fixing bolt 2 and the fixing nut 6, and the structure is simple and easy to manufacture.

[0058] In some technical solutions, a flexible pad is additionally arranged between the second fixing part 4 and the fixed object 1 to improve the ability of the vibration potential to conduct to the second fixing part 4.

[0059] In the embodiment, the first fixing part 3 and the second fixing part 4 are both arranged as two, and the two first fixing parts 3 and the two second fixing parts 4 are symmetrically arranged on both sides of the fixed object 1.

[0060] The force spring 5 is arranged as two, and the two force springs 5 are symmetrically arranged on both sides of the fixed object 1.

[0061] The gaskets 7 are arranged symmetrically on both sides of the fixed object 1.

[0062] In the technical solution, the first fixing member 3, the second fixing member 4, the gasket 7 and the force spring 5 are symmetrically arranged in two, and the degree of transmission of the potential energy of the vibration of the fixed object 1 to the end portions 201 of the fixing bolts 2 and the fixing nuts 6 on both sides is balanced, and the potential energy is absorbed through the structures on both sides to ensure the fixing effect.

[0063] In the embodiment, the first fixing member 3 is provided with a first extension portion 301, and the second fixing member 4 is provided with a second extension portion 401, and the first extension portion 301 and the second extension portion 401 extend to the outside of the fixed object 1.

[0065] The locking bolt 8 is arranged through the two first extension portions 301 and the two second extension portions 401, and the top portion is in abutment with the upper first fixing member 3.

[0066] The locking nut 9 is screwed on the locking bolt 8 and is in abutment with the lower first fixing member 3.

[0067] In the technical solution, the first extension portion 301 and the second extension portion 401 extend forward to the front side of the fixed object 1, the first extension portion 301 is provided with a circular clearance hole, the second extension portion 401 is provided with a second slot arranged in the left-right direction, the locking bolt 8 and the locking nut 9 are standard parts, the locking bolt 8 passes through the hole structures of the two first extension portions 301 and the two second extension portions 401, and the locking bolt 8 and the locking nut 9 are locked on both sides of the two first fixing members 3. In this way, the guiding effect of the first inclined surface and the second inclined surface on the first fixing member 3 and the second fixing member 4 is strengthened, the installation position requirement of the force spring 5 is reduced, and the torsion force generated by the force spring 5 when it is stretched on the first fixing member 3 and the second fixing member 4 is reduced.

[0068] In the embodiment, the locking nut 9 is arranged in two, and the two locking nuts 9 are arranged on both sides of the lower first fixing member 3.

[0069] The clamping member 10 is provided with two clamping portions, and the two clamping portions are clamped on the two locking nuts 9, respectively.

[0070] In the technical solution, the clamping portion is in the shape of C, the two clamping portions are connected through a plate-shaped portion to form the clamping member 10, and the clamping portion is clamped with the locking nut 9 through interference fit. In this way, the position fixing effect of the lower first fixing member 3 on the side where the fixing nut 6 is located is improved, and the possibility of loosening is reduced.

[0071] In some technical solutions, the thread length of the locking bolt 8 between the two locking nuts 9 needs to be adjusted by the gasket, so that the corresponding side surfaces of the two locking nuts 9 are coplanar or have a small angle difference after locking, facilitating the clamping of the clamping piece 10. At the same time, the clamping part of the clamping piece 10 can also be made of a material with a certain deformation ability.

[0072] In the embodiment, the third fixing piece 11 is further provided.

[0073] The third fixing piece 11 is provided with a guide hole and a limiting groove. The third fixing piece 11 is arranged on the locking bolt 8 through the guide hole, and the third fixing piece 11 is located between the two locking nuts 9. The two side surfaces of the limiting groove are respectively arranged in abutment with the two side surfaces of the fixing nut 6.

[0074] In the technical solution, the guide hole is an arc-shaped hole, and the limiting groove is a C-shaped groove. The third fixing piece 11 is arranged on the locking bolt 8 through the guide hole, is clamped on the two sides of the fixing nut 6 through the limiting groove, and is locked on the locking bolt 8 by the locking nut 9. In this way, the fixing effect of the fixing nut 6 can be improved, and the possibility of the fixing angle deflection of the fixing nut 6 during use can be reduced.
