In the figure: 1. a nut; 2. a main body; 3. a rectangular hole; 4. a reinforcing strip; 5. a threaded portion; 6. a friction pad; 7. a deformation section; 8. a circular opening; 9. an elliptical head, 401, an aluminum strip; 402. a copper bar; 403. and (4) iron bars.
Detailed Description
Referring to fig. 1-3, an anti-fracture thin workpiece carbon steel rivet nut comprises a nut 1, a main body 2 is fixedly installed on the lower surface of the nut 1, the main body 2 is cylindrical, a deformation portion 7 is arranged on the outer surface of the main body 2, rectangular holes 3 are uniformly distributed in the outer surface of the deformation portion 7, the number of the rectangular holes 3 is more than four, the rectangular holes are uniformly distributed on the outer surface of the main body 1, the strength of the main body 2 can be reduced through the arranged rectangular holes, the pressure applied to the deformation portion when the deformation portion is subjected to extrusion deformation is reduced, the working strength is reduced, reinforcing strips 4 are fixedly installed on the inner wall of the rectangular holes 3, a thread portion 5 is arranged on the inner wall of the main body 2, an elliptical head 9 is arranged below the thread portion 5, and the elliptical design can avoid scratching and damaging a plate to wait for fastening articles when in use.
Further, for the intensity that improves the nut, strengthen strip 4 and include aluminium strip 401, copper bar 402 and ironbar 403, according to the plasticity size of material, aluminium strip 401 is located the inboard, copper bar 402 is located the middle level, ironbar 403 is located the outside, when rivet the nut and take place to warp, inboard aluminium strip 401 deformation degree is the biggest, copper bar 402 is time, ironbar 403 is the minimum, improvement that can be very big warp 7 plasticity, play the effect of preventing breaking, and simultaneously, set up the ironbar 403 in the outside, very big improvement the intensity of nut.
Furthermore, in order to prevent the nut from rotating during working, the upper surface of the nut 1 is fixedly provided with the friction pad 6, and when the friction pad 6 is used, the air cavity is tightly attached to the friction pad 6, so that the friction force between the nut and the air gun is increased, and the occurrence of the air gun self-transmission phenomenon is effectively reduced.
Furthermore, the difference range between the diameter of the deformation part 7 and the thread part 5 is 0.25-0.45mm, the diameter difference range between the deformation part 7 and the thread part 5 is reasonable, the excessive range is avoided, the pressure required during deformation is large, the phenomenon of difficult use is caused, and the phenomenon of low strength and easy breakage of the deformation part caused by the excessively small range is avoided.
Further, for the intensity that improves the nut, the upper surface of nut 1 is equipped with circular opening 8, and the diameter of circular bayonet socket 8 is the same with the diameter of screw portion 5, uses bolt support to insert circular opening 8, can insert to screw portion 5 in, need not the calibration, and circular opening 8 extends to the deformation portion inboard, has improved the structural strength of nut.
In conclusion, according to the plasticity of the material, the aluminum strips 401 are located on the inner side, the copper strips 402 are located on the middle layer, and the iron strips 403 are located on the outer side, so that when the rivet nut deforms, the deformation degree of the inner aluminum strips 401 is the largest, the deformation degree of the inner copper strips 402 is the smallest, and the iron strips 403 are the smallest, the plasticity of the deformation part 7 can be greatly improved, the anti-snapping effect is achieved, and meanwhile, the strength of the nut is greatly improved due to the fact that the iron strips 403 arranged on the outermost side are arranged.
The diameter difference range between deformation portion 7 and screw thread portion 5 is reasonable, avoids the scope too big, and the pressure that needs when leading to warping is big, uses the phenomenon of difficulty to take place, avoids the scope undersize, leads to deformation portion intensity low easy cracked phenomenon to take place.
