[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). Special-shaped nuts refer to non-national standard nuts, non-standard parts, used in specific mechanical construction, and require design drawings. They are products with inner thread threads made through processing, surface treatment and other processes. Special-shaped nuts are often required in the assembly process of automobiles, but the anti-theft performance of special-shaped nuts in current automobiles is poor, especially the nuts used on automobile tires, which can be disassembled with a wrench to remove the tire, and their anti-theft performance is poor. Summary of the invention

[0003] In view of this, the technical problem to be solved by the present invention is to provide a special-shaped nut with an inner liner for automobiles to solve the problem of poor anti-theft performance of the prior art.

[0004] To achieve the above purpose, the present invention provides a special-shaped nut with lining for automobiles, comprising a shell and a nut body, wherein the shell is rotatably connected to the surface of the nut body, an auxiliary component is arranged inside the nut body, and an anti-theft component is arranged between the shell and the nut body; Among them, the anti-theft component includes two mounting rings that are symmetrically distributed and fixedly connected to the surface of the nut body, the outer side of the mounting ring is slidably connected to the inner side of the outer shell, the outer side of the mounting ring is provided with a sliding groove, the inner wall of the sliding groove is fixedly connected with a ring-shaped protrusion, and the cross-sectional shape of the protrusion is a right-angled trapezoid.

[0005] In the above technical solution, preferably, the anti-theft component also includes two active cavities opened inside the shell, the inner wall of the active cavity is slidably connected with a trigger plate, the cross-sectional shape of the trigger plate is T-shaped, a third spring is fixedly connected between one side of the trigger plate and the inner wall of the active cavity, and the other side of the trigger plate passes through the active cavity and extends to the interior of the adjacent slide groove.

[0006] In the above technical solution, preferably, two limit columns are slidably connected inside the active cavity, a mounting rod is fixedly connected between the limit columns inside the two active cavities, a sliding rod is fixedly connected to the top of the upper limit column, and a second spring is fixedly connected between the surface of the sliding rod and the inner wall of the outer shell.

[0007] In the above technical solution, preferably, a connecting screw hole is opened on the surface of the shell, the other end of the sliding rod extends to the inside of the connecting screw hole and is fixedly connected to a shielding plate, and the inner wall of the connecting screw hole is threadedly connected to a connecting bolt.

[0008] In the above technical solution, preferably, the auxiliary component includes a liquid storage chamber opened inside the nut body, the inner wall of the liquid storage chamber is slidably connected with a connecting plate, the top of the connecting plate and the inside of the liquid storage chamber are filled with hydraulic oil, a first spring is fixedly connected between the top of the connecting plate and the inner wall of the liquid storage chamber, the bottom of the connecting plate is fixedly connected with a connecting rod, the lower end of the connecting rod passes through the interior of the threaded groove of the nut body and is fixedly connected with a pressure plate.

[0009] In the above technical solution, preferably, the auxiliary component also includes two connecting cavities opened inside the nut body, the inner wall of the connecting cavity is slidably connected with an extrusion plate, an adjustment cavity is formed between one side of the extrusion plate and the interior of the connecting cavity, and a spring sheet is arranged between the other side of the extrusion plate and the inner wall of the connecting cavity, and the cross-sectional shape of the spring sheet is an arc shape.

[0012] Compared with the prior art, the present invention has the following beneficial effects: By setting up the anti-theft component, the anti-theft performance of the nut during use is effectively improved. When the correct operation process is not known for disassembly, the outer shell can only rotate idly and cannot drive the nut body to rotate, and then cannot drive the nut body to separate from the corresponding bolt, thereby improving the anti-theft performance. Through the mutual cooperation of the protrusion in the slide groove and the trigger plate, the nut body can be driven synchronously during the installation process, so that it can be installed normally, and the nut body can only be disassembled after the connecting bolts are installed during the disassembly process. When the nut body is not installed, only the idling outer shell cannot drive the nut body to rotate, thereby effectively improving the anti-theft performance.

[0013] By setting up an auxiliary component, the slide plate can be driven to slide along the inner wall of the sliding cavity during the installation of the nut body, until the resistance-enhancing block on the surface of the slide plate can be tightly attached to the surface of the bolt after it is installed in place, and the resistance-enhancing block is deformed due to extrusion, thereby increasing the friction between the bolt and the thread groove, thereby improving the stability of the nut body during use and reducing the possibility of the nut body loosening due to vibration during the use of the car.

DETAILED DESCRIPTION

[0016] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0018] like Figure 1-Figure 8 The illustrated automobile shaped nut with lining comprises a shell 1 and a nut body 101, wherein the shell 1 is rotatably connected to the surface of the nut body 101, an auxiliary component 2 is arranged inside the nut body 101, and an anti-theft component 3 is arranged between the shell 1 and the nut body 101; Among them, the anti-theft component 3 includes two mounting rings 301 that are symmetrically distributed and fixedly connected to the surface of the nut body 101. The outer side of the mounting ring 301 is slidably connected to the inner side of the outer shell 1. A sliding groove 302 is provided on the outer side of the mounting ring 301. The inner wall of the sliding groove 302 is fixedly connected with a ring-shaped protrusion 303, and the cross-sectional shape of the protrusion 303 is a right-angled trapezoid.

[0019] The nut body 101 is a relatively common technical means in the prior art application. It is provided with a thread groove corresponding to the bolt and is used as a fixing part in the automobile assembly process.

[0020] The setting of the shell 1 can cover the nut body 101. After the nut body 101 is installed, only the shell 1 can be rotated, but the shell 1 will slide along the outer side of the mounting ring 301 and will not drive the nut body 101 to rotate, so as to prevent criminals from directly removing the nut body 101 by tools such as wrenches.

[0021] like Figure 1-Figure 8 As shown, the anti-theft component 3 also includes two active cavities 309 opened inside the shell 1, and the inner wall of the active cavity 309 is slidably connected with a trigger plate 313, and the cross-sectional shape of the trigger plate 313 is T-shaped. A third spring 310 is fixedly connected between one side of the trigger plate 313 and the inner wall of the active cavity 309, and the other side of the trigger plate 313 passes through the active cavity 309 and extends to the interior of the adjacent slide groove 302.

[0022] Two limiting columns 312 are slidably connected inside the movable cavity 309, a mounting rod 311 is fixedly connected between the limiting columns 312 inside the two movable cavities 309, a sliding rod 306 is fixedly connected to the top of the upper limiting column 312, and a second spring 307 is fixedly connected between the surface of the sliding rod 306 and the inner wall of the outer shell 1.

[0023] A connecting screw hole 305 is formed on the surface of the housing 1 , the other end of the slide rod 306 extends into the inside of the connecting screw hole 305 and is fixedly connected to a shielding plate 308 , and a connecting bolt 304 is threadedly connected to the inner wall of the connecting screw hole 305 .

[0024] When the connecting bolt 304 is not installed under normal conditions, the sliding rod 306 can be driven by the second spring 307 to make the shielding plate 308 shield the opening of the connecting screw hole 305, so as to prevent criminals from observing the opening of the connecting screw hole 305. At the same time, the upward movement of the sliding rod 306 can drive the limiting column 312 to move upward synchronously through the installation rod 311. At this time, the limiting column 312 will not block the movement of the trigger plate 313, so that the trigger plate 313 can be driven to move synchronously when the housing 1 is rotated in the forward direction. In addition, since the cross-sectional shape of the protrusion 303 is a right-angled trapezoid, when the trigger plate 313 is rotated in the forward direction, the trigger plate 313 can be driven to move synchronously. During the movement of the trigger plate 313, it can be blocked by the side of the protrusion 303 with a slope, so that it drives the mounting ring 301 to rotate synchronously, and then drives the nut body 101 to move synchronously to achieve the effect of installing the nut body 101. When the shell 1 is rotated in the reverse direction, the trigger plate 313 can slide along the slope of the protrusion 303 and shrink to the inside of the active cavity 309. During this process, the third spring 310 can be compressed, thereby achieving the idling of the shell 1, so as to achieve the effect that the idling shell 1 cannot disassemble the nut body 101 when the criminals are unaware of the operation process.

[0025] When disassembly is required, the connecting bolt 304 is installed, and the sliding rod 306 can be pushed downward under the action of the connecting bolt 304. In this process, the limiting column 312 can be synchronously driven by the mounting rod 311 to be inserted into the movable cavity 309, thereby achieving the effect of limiting the position of the trigger plate 313. At this time, when the shell 1 is reversed, since the trigger plate 313 cannot shrink, when it contacts the inclined surface of the protrusion 303, it can push the protrusion 303 to drive the mounting ring 301 to make the nut body 101 move synchronously.

[0026] like Figure 1-Figure 8 As shown, the auxiliary component 2 includes a liquid storage chamber 201 opened inside the nut body 101, the inner wall of the liquid storage chamber 201 is slidably connected with a connecting plate 203, the top of the connecting plate 203 and the inside of the liquid storage chamber 201 are filled with hydraulic oil, a first spring 202 is fixedly connected between the top of the connecting plate 203 and the inner wall of the liquid storage chamber 201, the bottom of the connecting plate 203 is fixedly connected with a connecting rod 204, the lower end of the connecting rod 204 passes through the inside of the threaded groove of the nut body 101 and is fixedly connected with a pressure plate 205.

[0027] The auxiliary component 2 also includes two connecting cavities 208 opened inside the nut body 101, and the inner wall of the connecting cavity 208 is slidably connected with an extrusion plate 207, and an adjustment cavity is formed between one side of the extrusion plate 207 and the inside of the connecting cavity 208. A spring piece 210 is arranged between the other side of the extrusion plate 207 and the inner wall of the connecting cavity 208, and the cross-sectional shape of the spring piece 210 is an arc shape.

[0028] Two symmetrically distributed conduits 206 are disposed inside the nut body 101 , one end of the conduit 206 is connected to the liquid storage chamber 201 , and the other end of the conduit 206 is connected to the adjacent regulating chamber.

[0029] Two symmetrically distributed sliding cavities are provided inside the thread groove of the nut body 101, and a slide plate 211 is slidably connected to the inner wall of the sliding cavity. An adjusting rod 209 is fixedly connected between the slide plate 211 and the extrusion plate 207, and evenly distributed resistance-increasing blocks 212 are fixedly connected to the other side of the slide plate 211, and the resistance-increasing blocks 212 are rubber material components.

[0030] During the installation of the nut body 101, the matching bolt will gradually be inserted into the thread groove of the nut body 101. During this process, the pressure plate 205 can be pushed to move synchronously by the bolt, thereby driving the extrusion plate 207 to squeeze the hydraulic oil stored in the liquid storage chamber 201 through the connecting rod 204. The squeezed hydraulic oil can be injected into the adjusting chamber through the conduit 206, thereby pushing the extrusion plate 207 to slide along the inner wall of the connecting chamber 208. During this process, the spring piece 210 can be compressed, and the slide plate 211 can be driven to slide along the inner wall of the sliding chamber through the adjusting rod 209, until the resistance increasing block 212 on the surface of the slide plate 211 can be tightly attached to the surface of the bolt after being installed in place, and the resistance increasing block 212 is deformed due to the squeezing, which increases the friction between the bolt and the thread groove, thereby improving the stability of the nut body 101 during use and reducing the possibility of the nut body 101 loosening due to vibration during the use of the car.

[0031] Working principle: By setting the anti-theft component 3, the anti-theft performance can be improved during the use of the nut under the action of the anti-theft component 3. When the criminals are unaware of the operation process, the idling shell 1 cannot disassemble the nut body 101. At the same time, by setting the auxiliary component 2, the stability of the nut body 101 during use can be improved under the action of the auxiliary component 2, thereby reducing the possibility of the nut body 101 loosening due to vibration during the use of the car.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
