Description

Technical Field

[0001] The utility model relates to the technical field of automobile connecting parts, in particular to a high-strength anti-disassembly automobile nut. Background Art

[0002] A nut is a nut that is screwed together with a bolt or a screw for fastening. It is a component that all manufacturing machinery must use. According to the different materials, it is divided into several types, such as carbon steel, stainless steel, and non-ferrous metals (such as copper). Nuts are parts that tightly connect mechanical equipment. Through the inner thread, nuts and bolts of the same specifications can be connected together. For example, an M4-P0.7 nut can only be connected with an M4-P0.7 series bolt (in the nut, M4 refers to the inner diameter of the nut is about 4mm, and 0.7 refers to the distance between the two thread teeth is 0.7mm ); The same is true for American products. For example, a 1 / 4-20 nut can only be used with a 1 / 4-20 screw (1 / 4 means the inner diameter of the nut is approximately 0.25 inches, and 20 means there are 20 teeth in every inch). The DISC-LOCK anti-loosening nut is composed of two parts, each of which has staggered cams. Since the slope angle of the internal wedge design is greater than the nut angle of the bolt, this combination is tightly bitten into a whole. When vibration occurs, the raised parts of the DISC-LOCK anti-loosening nut shift against each other, generating lifting tension, thereby achieving a perfect anti-loosening effect.

[0003] The application number is CN202320436276.9, which discloses a high-strength anti-disassembly automobile nut, including a base, a nut body is fixedly connected to the top of the base, a locking assembly is provided on the top of the nut body, a nut sleeve is movably connected to the outer side of the nut body, and two clamping blocks are fixedly connected to the inner ring of the nut sleeve on both sides; the nut body includes a center block, an annular groove is provided on the outer side of the center block, and three T-shaped grooves and two holes are respectively provided on the top of the center block. The improved automobile nut is in a relative motion state between the nut sleeve and the center block through the cooperation between the reset spring, the clamping rod, the hole, the rotating seat, the nut sleeve, the clamping block, the annular groove and the annular clamping groove. The nut sleeve will not drive the center block to rotate, thereby realizing the anti-disassembly of the automobile nut, and the bolt is locked by the locking assembly, so that the connection between the bolt and the nut is tighter and not easy to loosen.

[0004] Although the above-mentioned utility model makes the nut sleeve and the center block in a state of relative motion through the cooperation between the reset spring, the clamping rod, the hole, the rotating seat, the nut sleeve, the clamping block, the annular slide groove and the annular clamping groove, the nut sleeve will not drive the center block to rotate, thereby realizing the anti-disassembly of the automobile nut, and the bolt is locked by the locking assembly, so that the connection between the bolt and the nut is tighter and not easy to loosen, but there is a disadvantage that there is still a small probability of loosening in the above-mentioned device, and the loosening cannot be completely avoided.

[0005] Therefore, it is necessary to replace the traditional nut assembly with the current anti-falling nut assembly so that when using the device, it can be installed through the limiting working principle of its internal parts. This way, the fixing effect is more stable and avoids the usual loosening and falling off. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1 - Figure 4 As shown, the utility model is a high-strength anti-disassembly automobile nut, comprising an anti-falling nut assembly 1, and a limited matching bolt 2 is installed in the middle of the anti-falling nut assembly 1;

[0027] The anti-dropping nut assembly 1 includes a nut body 101, the inner wall of the nut body 101 is provided with an installation groove 102, the inner wall of the installation groove 102 is installed with a limit installation assembly 103, and the interior of the limit installation assembly 103 is installed with a lubrication assembly 104. When using this device for fixing, firstly, the anti-dropping nut assembly 1 is threadedly rotated to correspond to the limit matching bolt 2.

[0028] By replacing the traditional nut assembly with the current anti-falling nut assembly 1, when using the device, it can be installed through the limiting working principle of its internal parts. Such a fixing effect is more stable and avoids the usual loosening and falling off.

[0029] The limiting matching bolt 2 includes a limiting head 201, a limiting rod 202 is installed on the rear side of the limiting head 201, and a rotating threaded rod 203 is installed on the end of the limiting rod 202. When the device is used for connection, the limiting matching bolt 2 is moved and fixed in the middle of the limiting installation component 103 of the anti-falling nut component 1. When the rotating threaded rod 203 rotates forward, the limiting installation component 103 in the anti-falling nut component 1 is expanded toward the inner wall until the rotating threaded rod 203 passes through and the limiting rod 202 reaches the inside.

[0030] The limit installation component 103 includes a resilient support spring 1031, and a spliced ​​threaded tube 1032 is installed on the outer side of the resilient support spring 1031. The inner wall of the spliced ​​threaded tube 1032 is provided with a threaded wall 1033. After the limit installation component 103 is reached by the set limit rod 202, the supporting force of the resilient support spring 1031 can push out the spliced ​​threaded tube 1032 installed on the outer side thereof and merge it into a ring and restrict it to the outer side of the limit rod 202. It is known that the diameter of the limit rod 202 is much smaller than the rotating threaded rod 203, so that the limit fixing component 103 restricted outside the limit rod 202 can restrict the forward and backward movement of the rotating threaded rod 203.

[0031] The lubrication component 104 includes an oil filling hole 1041, an oil storage chamber 1042 is opened inside the oil filling hole 1041, and an oil discharge hole 1043 is opened on the inner wall of the oil storage chamber 1042. At the same time, when the rotating threaded rod 203 rotates, the lubrication component 104 arranged inside the limiting installation component 103 can lubricate the rotating threaded rod 203 to avoid rust caused by long-term use, which in turn causes traction problems such as noise and jamming during connection.

[0032] The oil storage cavity 1042 includes a cavity 10421, an oil-absorbing sponge 10422 is installed inside the cavity 10421, and an extrusion plate 10423 is installed on the outer wall of the oil-absorbing sponge 10422. When lubrication is required, the extrusion plate 10423 can be squeezed inside during rotation to further squeeze the oil-absorbing sponge 10422 inside, and then the lubricating oil inside the oil-absorbing sponge 10422 is discharged through the inner oil outlet hole and lubricated on the inner rotating threaded rod 203.

[0033] When using this device, when using this device for fixing, firstly, the anti-falling nut assembly 1 is threadedly rotated to the corresponding limiting matching bolt 2. When using the device for connection, the limiting matching bolt 2 is moved and fixed to the middle of the limiting mounting assembly 103 of the anti-falling nut assembly 1. When the rotating threaded rod 203 rotates forward, the limiting mounting assembly 103 in the anti-falling nut assembly 1 is expanded toward the inner wall until the rotating threaded rod 203 passes through and reaches the inside by the limiting rod 202. After the limiting mounting assembly 103 is reached by the set limiting rod 202, the supporting force of the toughness support spring 1031 set therein can make the spliced ​​threaded tube 1032 installed on its outside be pushed out and merged into a ring and restricted to the outside of the limiting rod 202. It is known that the diameter of the limiting rod 202 is much smaller than the rotating thread The rod 203 can make the limiting fixing component 103 restricted outside the limiting rod 202 limit the forward and backward movement of the rotating threaded rod 203. At the same time, when the rotating threaded rod 203 rotates, the lubrication component 104 arranged inside the limiting installation component 103 can lubricate the rotating threaded rod 203 to avoid rust caused by long-term use, which in turn causes noise and traction problems such as jamming during connection. When lubrication is needed, during the rotating connection, the extrusion plate 10423 installed inside can be squeezed to further squeeze the oil-absorbing sponge 10422 installed inside, and then the lubricating oil inside the oil-absorbing sponge 10422 is discharged from the oil outlet hole inside and lubricated on the inner rotating threaded rod 203 to achieve lubrication and avoid rust.
