[0001] The invention relates to the technical field of nuts, in particular to a combined anti-loosening nut for automobiles. Background Art

[0002] Nuts and bolts are used together to form a set of commonly used fixing connectors in the mechanical field. They are used to fix the parts that need to be connected. They have good fixing performance in some stable working environments. However, the nuts used in automobiles will experience large vibrations due to the influence of the external environment during the movement of the automobile. The nuts may become loose if they are in such a working environment for a long time, which may lead to unreliable connection of the parts that need to be connected. If it is not discovered in time, serious consequences may occur. Summary of the invention

[0027] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0028] See also Figures 1 to 8 , the present invention provides a technical solution:

[0029] A combined anti-loosening nut for automobiles comprises a nut body 1, on which a bearing ring 11 is fixedly arranged, on which a connecting socket 12 is provided, the connecting socket 12 passes through the nut body 1, and a fixing cavity 13 is provided at the lower end of the connecting socket 12, negative pressure cavities 14 are symmetrically provided on both sides of the bearing ring 11, and mounting channels 15 are symmetrically provided at both ends of the bearing ring 11, movable channels 16 are symmetrically provided on both sides of the mounting channel 15, and mounting sockets 17 are provided in the movable channels 16, a through-hole 18 is provided on the bottom surface of the mounting channel 15, and an annular movable groove 19 is provided on the bearing ring 11 at the lower side of the mounting channel 15, and the through-hole 18 is connected with the annular movable groove 19, and a nut anti-loosening mechanism is provided on the nut body 1.

[0030] The nut anti-loosening mechanism includes a driving connecting ring 2, a supporting platform 3, a connecting spring 35 and a matching ring plate 4. The driving connecting ring 2 is located on the upper side of the bearing ring platform 11, and a matching groove 21 is symmetrically opened on the driving connecting ring 2. A matching bevel 22 is arranged in the matching groove 21, and the surface of the matching bevel 22 is smooth and free of burrs.

[0031] A plurality of connecting rods 23 are fixedly arranged on the circumference of the driving connecting ring 2, the connecting rods 23 are inserted in the connecting sockets 12, and a fixed plug plate 24 is fixedly arranged at the lower end of the connecting rod 23, the fixed plug plate 24 is inserted in the fixed cavity 13, and the diameter of the fixed plug plate 24 is equal to the inner diameter of the fixed cavity 13. Before the driving connecting ring 2 moves relative to the bearing ring platform 11, the lower end surface of the fixed plug plate 24 is flush with the end surface of the cavity opening of the fixed cavity 13.

[0032] A supporting rod 25 is symmetrically fixed on the driving connecting ring 2, and a matching plug plate 26 is fixed on the supporting rod 25. The matching plug plate 26 is inserted in the negative pressure cavity hole 14, and the diameter of the matching plug plate 26 is equal to the inner diameter of the negative pressure cavity hole 14. Before the driving connecting ring 2 moves relative to the supporting ring platform 11, the lower end surface of the matching plug plate 26 is in contact with the bottom of the negative pressure cavity hole 14. In this way, when the driving connecting ring 2 moves, negative pressure will be generated in the negative pressure cavity hole 14 under the action of the matching plug plate 26. Therefore, when it moves, it can drive the matching plug plate 26 to reset under the action of negative pressure, thereby ensuring the stability of the driving connecting ring 2.

[0033] The support platform 3 is installed in the installation channel 15, and a push-up connecting column 31 is fixedly provided on the upper end of one end of the support platform 3, and a matching supporting plate 32 is fixedly provided on the other end. In addition, before the driving connecting ring 2 moves relative to the bearing ring platform 11, the upper end of the push-up connecting column 31 contacts the matching inclined surface 22.

[0034] A fixing insertion hole 33 is formed at the lower end of the matching support plate 32 , and mounting insertion rods 34 are symmetrically fixedly disposed on both sides of the matching support plate 32 .

[0035] The installation plug rod 34 passes through the movable insertion channel 16 and is inserted into the installation insertion hole 17 , and a connecting spring 35 is sleeved on the installation plug rod 34 .

[0036] The two ends of the connecting spring 35 are fixed on the matching support plate 32 and the inner wall of the movable insertion channel 16 respectively.

[0037] The matching ring plate 4 is installed in the annular movable groove 19 , and fixed plug posts 41 are symmetrically fixedly provided on the matching ring plate 4 , and the fixed plug posts 41 are inserted into the through holes 18 .

[0038] An elastic connecting piece 42 is also circumferentially fixed on the mating ring plate 4, and the upper end of the elastic connecting piece 42 is fixed on the inner top surface of the annular movable groove 19. In addition, before the support table 3 moves, its lower end surface is in contact with the upper end surface of the fixed plug 41. At this time, the elastic connecting piece 42 is in a stretched state, and the fixed plug 41 is inserted into the fixed socket 33 when it fixes the support table 3.

[0039] When the nut body 1 is screwed firmly, it is in contact with the surface of the component to be connected. In this way, the fixed cavity hole 13 is in a sealed state under the action of the component to be connected, and at the same time, the two matching support plates 32 are pushed toward each other, so that the push-up connecting column 31 can be carried to move. In this way, the push-up connecting column 31 and the matching inclined surface 22 will push the driving connecting ring 2 to move in the direction away from the bearing ring platform 11. As the driving connecting ring 2 moves, a negative pressure will be generated in the fixed cavity hole 13 under the action of the fixed plug plate 24, and then the nut body 1 can be fixed to the surface of the component to be connected under the action of the negative pressure, so that it cannot rotate, thereby effectively preventing the nut from loosening. As the driving connecting ring 2 moves, a negative pressure can be generated in the negative pressure cavity hole 14 under the action of the matching plug plate 26. In this way, when the push-up connecting column 31 no longer supports the driving connecting ring 2, the driving connecting ring 2 can be smoothly reset. In addition, as the support table 3 moves, the fixed pin 41 will be aligned with the fixed hole 33. In this way, under the action of the elastic connecting piece 42, the fixed pin 41 will be inserted into the fixed hole 33 to achieve the fixation of the support table 3. Through the fixation of the support table 3, the push-up connecting pin 31 can be stably supported on the driving connecting ring 2, which can ensure the stability of the driving connecting ring 2, and then ensure the stability of the negative pressure in the fixing cavity 13, thereby achieving a long-term fixing effect on the nut body 1 and avoiding it from loosening. When the nut body 1 needs to be disassembled, the matching ring plate 4 is pushed to make the fixed pin 41 withdraw from the fixed hole 33, so that the support table 3 is in an active state, so that it is reset under the action of the connecting spring 35, and the support of the push-up connecting pin 31 is lost, which also makes the driving connecting ring 2 reset, and the nut body 1 can be screwed.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
