Definitions

  • the present invention relates to a washer for preventing loosening of a standard nut used together and a structure for preventing a nut from being loosened using the washer.
  • a nut body incorporating an elastic body such as a metal elastic plate, a nylon plate, or a spring is generally known.
  • the present invention is to provide a hash capable of exerting a powerful locking effect on a conventional standard nut at a cost that is almost the same as that of a conventional washer by modifying the washer used simultaneously. Its primary purpose.
  • Another important object of the present invention is to provide a nut locking structure using the above-mentioned washer.
  • the present invention takes the following technical measures. That is, in the locker for preventing loosening according to the present invention, at least one surface of the upper and lower surfaces of the ring-shaped washer body 2 having the bolt 1 and the through hole 1 penetrating the shaft core is gently inclined in one direction. The structure was formed on the surface.
  • the washer of the present invention when the nut B is screwed together with the washer A to the bolt D and tightened to the member C to be tightened with a predetermined torque, the lower surface of the nut B Is in close contact with the upper surface of the washer A, and the inclined seating surface 3 is pressed against the upper surface of the member C to be tightened.
  • the angle is set within the range of possible angles.
  • At least one of the upper and lower seating surfaces 3 of the upper and lower surfaces of the ring-shaped washer body 2 having the bolt insertion holes 1 penetrating the shaft core is formed as a gentle inclined surface which is inclined in one direction to form the washer A.
  • the nut B is screwed to the bolt D and tightened to the tightened member C with a predetermined torque, so that the lower surface of the nut B is tightly attached to the upper surface of the nut A.
  • the inclined seat surface 3 of the shaft is pressed against the upper surface of the member C to be tightened, thereby simultaneously generating the pressure in the axial direction of the bolt and the surface pressure against the member C to be tightened to prevent the nut from loosening. It is also characterized by a nut-preventing structure.
  • FIG. 1 is a partial cross-sectional front view showing an embodiment of a locker for preventing loosening according to the present invention.
  • FIG. 2 is a plan view of the above-mentioned pusher.
  • FIG. 3 is a sectional view showing a process of using the above-mentioned washer.
  • FIG. 4 is a sectional view showing the use state of the above-mentioned washer. Detailed description of the invention
  • reference numeral A denotes a washer according to the present invention, in which a washer body 2 formed of a ring body made of a metal plate is provided with a bolt insertion hole 1 that penetrates a shaft c. 3 is formed on an inclined surface that is gently inclined in the direction of the arrow.
  • the angle of inclination that is, the angle of the seat surface varies depending on the size, but is preferably about 1.0 to 3.0 degrees.
  • the predetermined tightening torque referred to above is equivalent to the standard tightening torque of the standard nut, or refers to a torque added by about 10% to the standard tightening torque. 0 to 50 O kgf.cm.
  • the washer A configured as described above is used together with the nut B as shown in FIG. After the nut B is screwed along the bolt D toward the member C to be tightened to bring the washer A into contact with the upper surface of the member C to be tightened, the nut B is further tightened to a predetermined torque.
  • the nut B is fixed in the inclined posture along the inclined seat surface 3 of the washer A while filling the gap between the bolt and the nut, and the gap between the nuts.
  • the screw on the upper side of the nut B and the screw on the lower side press the bolt side in the cutting direction, and at the same time, the inclined seat surface 3 is tightened. Pressure contact with the upper surface of member C by surface contact. Due to this internal stress, the engagement between the nut B and the screw of the bolt D is firmly locked, so that the nut B can be prevented from becoming loose.
  • the inventor of the present invention has an outer diameter of 26 im, an inner diameter of 12.2, a maximum thickness of 2.8 mm, and a minimum thickness of 1.8 mm (in this case, the seat angle is 2.3 degrees).
  • An iron shell for M12 nuts was created, and a third-party test center was asked to perform a nut loosening vibration test.As a result, all four standard nuts loosened within 20 seconds. All four nuts were able to withstand more than 14 minutes of vibration. In this case, the tightening torque of the nut was 50 O kgf .cm.
  • the present invention is not necessarily limited to the structures of these embodiments.
  • the inclined surface is provided on the lower surface of the washer body.
  • the washer material is not limited to metal materials such as iron and stainless steel, and a small-sized one can be formed of a synthetic resin material.
  • the shape of the washer is not limited to a circle, but may be any shape such as a hexagon or a quadrangle. May be formed.
  • the present invention has the structural requirements, achieves the object of the present invention, and can be appropriately modified and implemented within the range of achieving the following effects.
  • the inclined surfaces are formed on at least one of the upper and lower surfaces of the washer body, the production can be simplified, and the price is almost the same as that of the conventional standard dozer.
  • it can be provided with a standard nut, it can be used together with a standard nut to generate internal stress in the bolt axis direction inside the nut body and surface pressure on the bearing surface, so that a reliable locking effect is exhibited.
  • the bolts of the nuts can be lightly screwed in exactly the same way as the standard nuts, so that there are various excellent effects such as good work efficiency.

Abstract

Rondelle qui comprend un corps (2) annulaire doté d'un trou (1) d'introduction de vis s'étendant verticalement dans le centre de ladite rondelle et dont l'une des surfaces supérieure et inférieure est légèrement inclinée dans un sens. Lorsqu'un écrou (B), avec une rondelle (A), est vissé sur une vis (D) à fixer dans un élément (C) selon un couple prédéterminé, une surface inférieure de l'écrou (B) vient en contact étroit avec une surface supérieure de la rondelle (A) et une surface (3) de siège inclinée vient en contact par pression avec une surface supérieure de l'élément (C) devant être fixé. La pression dans un sens de l'axe de la vis et une pression sur la surface de l'élément (C) devant être fixé sont générées simultanément, ce qui empêche de manière efficace le desserrage de l'écrou.
