Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention.

[0029] Example 1

[0030] Reference Figures 1 to 6 , which is the first embodiment of the utility model, and this embodiment provides an anti-loosening six-spline nut, including a nut main body mechanism 1, the surface of the nut main body mechanism 1 is provided with a chamfer 2, the surface of the nut main body mechanism 1 is sleeved with a first anti-loosening mechanism 3, the surface of the nut main body mechanism 1 is penetrated by a second anti-loosening mechanism 4, and the front of the nut main body mechanism 1 is provided with a third anti-loosening mechanism 5.

[0031] By adopting three anti-loosening structures in combination, if one of the anti-loosening structures is damaged during use, the other two anti-loosening structures can still ensure the anti-loosening effect, which greatly improves the safety of the anti-falling six-spline nut when in use, and solves some defects that still exist in the existing anti-loosening six-spline nut during use, such as only having a single anti-loosening structure, and being unable to use multiple anti-loosening structures in combination. A single anti-loosening structure is easily damaged during use, thereby causing the anti-loosening effect to fail, posing a safety hazard, affecting the normal use of the anti-falling six-spline nut, and failing to meet the current market demand.

[0032] Example 2

[0033] Reference Figures 1 to 6 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0034] Specifically, the nut body mechanism 1 includes a hexagonal nut 101 , and an anti-loosening mechanical thread 102 is formed on the inner wall of the hexagonal nut 101 .

[0035] The hexagonal nut 101 is convenient for the user to rotate the six-spline nut by using tools. The anti-loosening mechanical thread 102 is a self-locking thread. The self-locking thread utilizes the special geometric shape of the thread to generate friction to prevent the nut from loosening when the thread pair is subjected to axial load, such as increasing the thread lead angle or changing the tooth profile, etc. The self-locking ability of the thread can also be improved by increasing the contact area and friction coefficient between the threads. When the thread is tightened, the larger friction makes the nut not easy to loosen.

[0036] Specifically, the first anti-loosening mechanism 3 includes an anti-loosening plate 301 , and an anti-loosening groove 302 is formed on the surface of the anti-loosening plate 301 .

[0037] The inner wall of the anti-loosening plate 301 is fixedly connected to the surface of the hexagonal nut 101 by welding. The welding connection method can ensure the tightness of the connection between the anti-loosening plate 301 and the hexagonal nut 101. By setting the anti-loosening plate 301, the contact area between the hexagonal nut and the supporting surface can be increased. By setting the anti-loosening groove, the friction coefficient of the anti-loosening plate 301 can be increased. By increasing the contact area and the friction coefficient, the contact area between the hexagonal nut and the supporting surface can be increased, thereby improving the anti-loosening ability of the hexagonal nut.

[0038] Specifically, the second anti-loosening mechanism 4 includes a fixing screw 401 , and a fixing screw hole 402 used in conjunction with the fixing screw 401 is provided on the surface of the nut body mechanism 1 .

[0039] The fixing screw holes 402 are opened on the surface of the hexagonal nut 101, and there are two of them. The number of the fixing screw rods 401 can be one or two, which can be selected according to the use requirements. After the hexagonal nut is tightened, the user rotates the fixing screw rod 401 to insert it into the fixing screw hole 402, and the fixing screw 401 continues to be inserted until it is pressed against the threaded rod in the inner cavity of the hexagonal nut. The limitation of the fixing screw 401 can prevent the hexagonal nut from rotating loose.

[0040] Specifically, the third anti-loosening mechanism 5 includes a receiving groove 501 , and an anti-loosening gasket 502 is fixedly connected to the inner wall of the receiving groove 501 .

[0041] The anti-loosening gasket is fixed to the inner wall of the receiving groove 501 by adhesive. The provision of the anti-loosening gasket can further increase the friction between the six-spline nut and the supporting surface, thereby further preventing the six-spline nut from self-rotation and loosening, thereby improving the safety of the six-spline nut when in use.

[0042] Specifically, the nut main body mechanism 1 and the first anti-loosening mechanism 3 are made of the same material, and the anti-loosening gasket 502 is made of a wear-resistant rubber gasket.

[0043] Specifically, the nut body structure 1 includes a base layer 1001, the outer surface of the base layer 1001 is fixedly connected to a reinforcing layer 1002, the outer surface of the reinforcing layer 1002 is fixedly connected to an insulating layer 1003, the outer surface of the insulating layer 1003 is fixedly connected to a protective layer 1004, the reinforcing layer 1002 includes a first strength layer 10021 and a second strength layer 10022, and the protective layer 1004 includes an anti-corrosion layer 10041 and an anti-corrosion and wear-resistant layer 10042.

[0044] Specifically, the second strength layer 10022 is located on the outer surface of the first strength layer 10021 , and the anti-corrosion and wear-resistant layer 10042 is coated on the outer surface of the anti-corrosion layer 10041 .

[0045] Specifically, the base layer 1001 is made of high-strength steel, and the insulating layer 1003 is made of polyimide material.

[0046] High-strength steel has high yield strength and tensile strength, can withstand large loads, and ensure the stability and safety of the structure. Good toughness: While having high strength, it also has a certain toughness, can absorb impact energy, and prevent brittle fracture. Excellent fatigue performance: It can maintain good performance under repeated alternating loads, and is not prone to fatigue cracks and failures. Polyimide materials can work stably for a long time in high temperature environments, can withstand very high temperatures, and have excellent insulation properties. It is an excellent electrical insulation material. Good mechanical properties: high strength, wear resistance, and impact resistance.

[0047] Specifically, the material of the first strength layer 10021 is titanium carbonitride, the material of the second strength layer 10022 is chromium nitride, the material of the anti-corrosion layer 10041 is glass fiber coating, and the material of the anti-corrosion and wear-resistant layer 10042 is metal-based ceramic composite material.

[0048] The use of the first strength layer 10021 and the second strength layer 10022 can greatly improve the usability of the six-spline nut. Titanium carbonitride has the following advantages: high hardness: the titanium carbonitride coating has a high hardness, which can improve the wear resistance and cutting performance of tools such as cutting tools and molds; wear resistance: its wear resistance is better than that of the titanium nitride coating, and it is suitable for high wear environments; good oxidation resistance: in high temperature environments, the titanium carbonitride coating can still maintain good oxidation resistance; strong adhesion: it has strong adhesion to the base material and is not easy to peel off; chromium nitride has the following advantages: strong corrosion resistance: the chromium nitride coating has good corrosion resistance and can be used to protect the metal surface from corrosion; high hardness: it can effectively improve the hardness and wear resistance of the surface; good high temperature stability: it can still maintain its performance at high temperatures. The glass fiber and metal-based ceramic composite material can improve the corrosion resistance and wear resistance of the six-spline nut, prevent the six-spline nut from being easily damaged during use, and extend the service life of the six-spline nut.

[0049] When in use, the user sets the six-spline nut on the surface of the threaded rod and tightens it. The anti-loosening mechanical thread 102 is a self-locking thread. The self-locking thread utilizes the special geometric shape of the thread to generate friction to prevent the nut from loosening when the thread pair is subjected to axial load, such as increasing the thread lead angle or changing the tooth profile. The self-locking ability of the thread can also be improved by increasing the contact area and friction coefficient between the threads. When the threads are tightened, the greater friction makes it difficult for the nut to loosen. By providing an anti-loosening plate 301, the contact area between the six-spline nut and the supporting surface can be increased. By providing an anti-loosening groove, the friction coefficient of the anti-loosening plate 301 can be increased. By increasing the contact area and increasing the friction coefficient, the contact between the six-spline nut and the supporting surface can be increased. The fixing screw 401 is inserted into the fixing screw hole 402 by the user after the six-spline nut is tightened, and the fixing screw 401 continues to be inserted until it is pressed against the threaded rod in the inner cavity of the six-spline nut. The limitation of the fixing screw 401 can prevent the six-spline nut from self-rotation and loosening. The friction between the six-spline nut and the supporting surface can be further increased by setting the anti-loosening gasket, thereby further preventing the six-spline nut from self-rotation and loosening, thereby improving the safety of the six-spline nut when in use. By adopting three anti-loosening structures for cooperation, if one of the anti-loosening structures is damaged during use, the other two anti-loosening structures can still ensure the anti-loosening effect, thereby greatly improving the safety of the anti-falling six-spline nut when in use.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
