Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of automobile parts, and particularly relates to an automobile anti-theft nut. Background Art
[0002] The main purpose of the nuts for large truck wheel hubs is to ensure a tight and stable connection between the wheel hub and the tire. The nuts for large truck wheel hubs are usually made of high-strength alloy steel to ensure that they have sufficient strength and durability.
[0003] Common automobile nuts may be disassembled by criminals using tools during use, resulting in the theft of internal parts of large trucks and causing economic losses. At the same time, due to the vibration of large trucks during driving, these nuts may also become loose, resulting in unstable connections between large truck parts, which may cause various safety accidents. In view of this, we propose an automobile anti-theft nut. Utility Model Content
[0004] The purpose of the utility model is to provide an automobile anti-theft nut to solve the problems raised in the above background technology.
[0005] In view of this, the utility model provides an automobile anti-theft nut, comprising:
[0006] A threaded column 1, wherein a threaded sleeve is threadedly mounted on the threaded column 1, an outer circumferential side wall of the threaded sleeve is provided with an anti-theft shell, and an inner circumferential side wall of the anti-theft shell is in close contact with an outer circumferential side wall of the threaded sleeve;
[0007] Two fixing components, both of which are located in the anti-theft shell and are used to fix the position of the anti-theft shell;
[0008] A driving shell, the driving shell is arranged on the top of the threaded column 1, and the driving shell is located above the threaded sleeve, the driving shell is provided with two sliding grooves 1, a sliding rod is slidably installed in the sliding groove 1, the lower ends of the two sliding rods respectively penetrate the two sliding grooves 1 and extend to the outside, and the lower ends of the two sliding rods are fixedly connected to the top of the threaded sleeve;
[0009] A power chamber, the power chamber is opened in the driving shell, and two sliding plates are slidably installed in the power chamber, and the two sliding plates are both located on the outer peripheral side wall of the threaded column one;
[0010] The driving assembly is located in the driving housing and is used to drive the two sliding plates to move closer to each other or away from each other.
[0011] In the technical scheme, when the threaded sleeve needs to be installed on the threaded column one, the anti-theft shell can be rotated by cooperating with the tool and the anti-theft shell, and the anti-theft shell drives the threaded sleeve to rotate. Under the action of the thread, the threaded sleeve will rotate downward on the threaded column one, and the threaded sleeve drives the driving shell to rotate. At the same time, the two sliding rods will slide downward in the two sliding grooves one respectively, so that the application range of the device is large. When the threaded sleeve is installed, the two sliding plates can be driven to slide and approach each other through the set driving component. When the anti-skid rubber on the two sliding plates is in close contact with the outer circumferential side wall of the threaded column one, the fixing effect of the threaded sleeve is strengthened. The anti-theft shell can be taken out upwards through the set fixing component. The surface of the threaded sleeve is coated with lubricating oil, which makes it inconvenient for personnel to disassemble the threaded sleeve with the help of tools, thereby achieving the anti-theft effect.
[0012] When the threaded sleeve needs to be removed, the driving assembly can be used to drive the two sliding plates to slide and approach each other, and then the anti-slip rubber pads on the two sliding plates no longer contact the outer circumferential side wall of the threaded column one. Through the fixed assembly, the anti-theft shell can be rotated by a tool, and the anti-theft shell can drive the threaded sleeve to rotate through the two limit columns, so that the threaded sleeve can be removed.

[0015] In this technical solution, a person manually pulls the two limit posts to slide and move away from each other, and at the same time, a number of springs are squeezed and contracted. When the other sides of the two limit posts are respectively separated from the two limit grooves, the anti-theft shell can be taken out upwards;
[0016] The personnel pull the two limit columns by hand to slide and move away from each other, and at the same time, several springs are squeezed and contracted, and then the anti-theft shell is placed on the outer circumferential side wall of the threaded sleeve. When the other sides of the two springs are respectively located on one side of the two limit grooves, the personnel loosen the two limit columns. Under the action of the rebound force of the several springs, the two limit columns slide and approach each other, and then the two limit columns are respectively inserted into the two limit grooves. At this time, the anti-theft shell can be rotated by a tool, and the anti-theft shell can drive the threaded sleeve to rotate through the two limit columns, so that the threaded sleeve can be removed.
[0017] In the above technical solution, further, the driving component includes:

[0019] In this technical solution, a person uses a tool to rotate the threaded column 2 in the positive direction. Under the action of the thread, the threaded column 2 drives the two sliding plates to slide and approach each other. When the anti-slip rubber on the two sliding plates is in close contact with the outer circumferential side wall of the threaded column 1, the fixing effect of the threaded sleeve is enhanced.
[0020] When the threaded sleeve needs to be disassembled, first use the tool to rotate the threaded column 2 in the opposite direction. Under the action of the thread, the threaded column 2 drives the two sliding plates to slide and approach each other, and then the anti-slip rubber pads on the two sliding plates no longer contact the outer circumferential side wall of the threaded column 1.

[0022] In the technical solution, when the anti-skid rubber on the two sliding plates is in close contact with the outer circumferential side wall of the threaded column, the fixing effect of the threaded sleeve is enhanced.
[0023] In the above technical solution, further, the two limiting columns are distributed in a ring shape with equal intervals.
[0024] In this technical solution, it is ensured that the two limiting columns can drive the threaded sleeve to rotate.
[0025] In the above technical solution, further, the inner diameter of the anti-theft shell is larger than the outer diameter of the driving shell, and the side of the sliding plate close to the threaded column 1 is arranged in an arc shape.
