Stud bolt with good anti-loosening effect

Abstract

The utility model discloses a double-end bolt with a good anti-loosening effect, which relates to the technical field of double-end bolts and comprises a double-end bolt, and nuts are screwed on two sides of the double-end bolt. Metal gaskets are connected to the opposite sides of the nuts on the two sides in an attached mode. Rubber gaskets are arranged on the opposite sides of the metal gaskets on the two sides; magnet cylinders are arranged on the sides, away from each other, of the metal gaskets on the two sides; inner hexagonal cylinders are connected to the inner walls of the magnet cylinders on the two sides in an attached mode, and the inner hexagonal cylinders are attracted and fixed into the magnet cylinders. The inner hexagonal barrel is connected to the outer side of the nut in a sleeving mode, the inner hexagonal barrel also needs to rotate on the metal gasket when the nut rotates accidentally, so that rotation resistance is increased, the inner hexagonal barrel is attracted and fixed to the magnet barrel, the inner hexagonal barrel is difficult to rotate on the magnet barrel, and therefore the nut is difficult to rotate; therefore, the possibility of loosening of the double-end nut is further reduced.

Description

Technical Field

[0001] The utility model relates to the technical field of stud bolts, in particular to a stud bolt with good anti-loosening effect. Background Art

[0002] Stud bolts are used for the fixed link function of connecting machinery. There are threads on both ends of the stud bolts, and the screw in the middle can be thick or thin. They are generally used in mining machinery, bridges, automobiles, motorcycles, boiler steel structures, tower cranes, large-span steel structures and large buildings.

[0003] The two sides of the existing stud bolts are generally fastened only by nuts, which has a poor anti-loosening effect and is easily loosened due to external factors after long-term use. Therefore, we propose a stud bolt with good anti-loosening effect. Utility Model Content

[0004] The purpose of the utility model is to provide a stud bolt with good anti-loosening effect to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solution: a stud bolt with good anti-loosening effect, comprising: a stud bolt, both sides of which are screwed with nuts;

[0006] The opposite sides of the nuts on both sides are fitted with metal washers;

[0007] Rubber gaskets are provided on opposite sides of the metal gaskets on both sides;

[0008] A magnet tube is provided on each side of the metal gaskets that are away from each other;

[0009] The inner walls of the magnet tubes on both sides are fitted with inner hexagonal tubes, and the inner hexagonal tubes are adsorbed and fixed in the magnet tubes;

[0010] The hexagonal inner tubes on both sides are respectively fitted onto the nuts on both sides.

[0011] As a preferred solution of the stud bolt with good anti-loosening effect described in the utility model, anti-slip protrusions that contact the nut are evenly arranged on the sides of the metal washers that are away from each other.

[0012] As a preferred solution of the stud bolt with good anti-loosening effect described in the utility model, the thickness of the nut is greater than the thickness of the hexagonal inner tube.

[0013] As a preferred solution of the stud bolt with good anti-loosening effect described in the utility model, the thickness of the hexagonal inner tube is greater than the thickness of the magnet tube.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. After the stud bolts are installed, the rubber gasket contacts the surface of the parts, increasing the friction resistance, thereby increasing the resistance to accidental rotation of the nut and reducing the possibility of the stud bolts loosening;

[0016] 2. The nut contacts the anti-slip protrusions on the metal washer, further increasing the friction resistance;

[0017] 3. By sleeved the hexagonal tube on the outside of the nut, the hexagonal tube will also rotate on the metal gasket when the nut rotates accidentally, thereby increasing the rotation resistance. The hexagonal tube is adsorbed and fixed on the magnet tube, making it difficult for the hexagonal tube to rotate on the magnet tube, thereby making it difficult for the nut to rotate, thereby further reducing the possibility of the stud nut loosening.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] As mentioned in the background art, in order to solve the problem of poor anti-loosening effect in the prior art, the present invention provides a stud bolt with good anti-loosening effect.

[0022] Example 1

[0023] Reference Figure 1 A stud bolt with good anti-loosening effect, comprising a stud bolt 1, with nuts 2 screwed on both sides of the stud bolt 1;

[0024] The opposite sides of the nuts 2 on both sides are fitted with metal washers 3;

[0025] The opposite sides of the metal gaskets 3 on both sides are provided with rubber gaskets 4, which are used to contact with components;

[0026] A magnet tube 6 is provided on each side of the metal gaskets 3 that are away from each other, and the metal gaskets 3 are fixedly connected to the magnet tube 6;

[0027] The inner walls of the magnet tubes 6 on both sides are fitted with inner hexagonal tubes 5, and the inner hexagonal tubes 5 are adsorbed and fixed in the magnet tubes 6. The inner hexagonal tubes 5 on both sides are respectively fitted and sleeved on the nuts 2 on both sides to fix the inner hexagonal tubes 5, thereby further fixing the nuts 2.

[0028] The metal washers 3 on both sides are evenly provided with anti-slip protrusions that contact the nuts 2 on the sides away from each other, thereby further increasing the friction resistance.

[0029] Example 2

[0030] Reference Figure 1 The thickness of the nut 2 is greater than the thickness of the hexagonal inner tube 5, which does not affect the rotation of the nut 2. The thickness of the hexagonal inner tube 5 is greater than the thickness of the magnet tube 6, which does not affect the removal of the hexagonal inner tube 5.

[0031] The rest of the structure is the same as that of Example 1.

[0032] After placing the stud bolt 1, insert the metal gasket 3 and the rubber gasket 4, so that the rubber gasket 4 contacts the parts to increase friction, and then tighten the nut 2 so that the nut 2 contacts the anti-slip protrusion of the metal gasket 3, which can further increase friction. Finally, insert the hexagonal tube 5 into the outside of the nut 2, so that it is adsorbed and fixed with the magnet tube 6. The bottom of the hexagonal tube 5 contacts the metal gasket 3, which further increases friction. The magnet tube 6 provides resistance to the rotation of the hexagonal tube 5, which can provide resistance to the rotation of the nut 2, thereby making the nut 2 more anti-loosening effect.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
