[0002] A bolt is a mechanical part, a cylindrical threaded fastener used with a nut. It consists of a head and a shank (a cylinder with external threads), and is used to fasten two parts with through holes.

[0003] Existing automotive bolts that are not easy to slip have an unsatisfactory fixing effect. They may fall off during normal driving due to vehicle shaking after being fixed, which may even cause a vehicle accident in serious cases. Therefore, we propose an automotive bolt that is not easy to slip. Utility Model Content

[0004] The purpose of this invention is to provide a non-slip automotive bolt to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a non-slip automotive bolt, comprising:

[0006] A bolt, wherein a hexagonal nut is fixedly installed on the top of the bolt, and an opening groove is provided inside the bolt. Multiple mounting grooves are provided on the inner side wall of the opening groove, and sliding grooves are symmetrically provided on both sides of the multiple mounting grooves.

[0007] Multiple first anti-slip plates are rotatably installed at the bottom of multiple mounting slots. A second mounting buckle is fixedly installed at the top of each of the multiple mounting slots. A second anti-slip plate is provided above each of the multiple first anti-slip plates. A first mounting buckle is fixedly installed at the bottom of each of the multiple second anti-slip plates. The multiple second mounting buckles are rotatably connected to the multiple first mounting buckles.

[0008] A threaded post is fixedly installed on the inner bottom surface of an open slot. A threaded sleeve is provided on the outer side wall of the threaded post, and an installation sleeve is provided on the outer side wall of the threaded sleeve.

[0009] Multiple sets of adjustment components are provided, all of which are disposed within the opening slot and are used to adjust the rotation angle of multiple first anti-slip plates.

[0010] In the above technical solution, the adjustment component further includes a second mounting base, which is fixedly installed on one side of the first anti-slip plate. A push rod is rotatably installed inside the second mounting base. A first mounting base is fixedly installed on the outer wall of the mounting sleeve. One end of the push rod is rotatably connected to the first mounting base.

[0011] In this technical solution, multiple first anti-slip plates can be adjusted and moved simultaneously when the cross nut is rotated to move the mounting sleeve, which is simple and practical.

[0012] In the above technical solution, a cross nut is further provided above the threaded post, the bottom surface of the cross nut is fixedly connected to the top end of the threaded sleeve, and the bottom surface of the cross nut is rotatably connected to the top end of the mounting sleeve.

[0013] In this technical solution, the mounting sleeve will not interfere with the threaded sleeve and cause it to jam when the cross nut is rotated and the threaded sleeve moves on the threaded post. It is simple and practical.

[0014] In the above technical solution, furthermore, the two sides of the plurality of second anti-slip plates are slidably installed in the plurality of grooves respectively.

[0015] In this technical solution, it is convenient for multiple first anti-slip plates to expand outward and drive multiple second anti-slip plates to move, while the multiple second anti-slip plates can move more in sync with the multiple first anti-slip plates, which is simple and practical.

[0016] In the above technical solution, the outer wall of the threaded column is further connected to the inner wall of the threaded sleeve by threads.

[0017] In this technical solution, a Phillips screwdriver is aligned with a Phillips nut and the nut is rotated. As the nut rotates, the threaded sleeve moves on the threaded post, and the mounting sleeve moves synchronously. The thread design allows workers to control the number of turns of the Phillips nut by adjusting the expansion size as needed, making it simple and practical.

[0018] In the above technical solution, the outer wall of the threaded sleeve is rotatably connected to the inner wall of the mounting sleeve.

[0019] In this technical solution, the mounting sleeve will not interfere with the threaded sleeve and cause it to jam when the cross nut is rotated and the threaded sleeve moves on the threaded post. It is simple and practical.

[0020] In the above technical solution, the outer wall of the bolt is further provided with threads.

[0021] In this technical solution, workers can easily install the bolts directly into the corresponding mounting holes, making it simple and practical.

[0022] The beneficial effects of this utility model are:

[0023] This non-slip automotive bolt is designed so that during installation, the worker places the bolt into the pre-drilled mounting hole on the vehicle. First, the worker uses a vise to clamp the hexagonal nut and rotates the bolt to insert it into the hole. After ensuring installation, the worker uses a Phillips head screwdriver, aligning it with the Phillips head nut and turning it. As the nut rotates, the threaded sleeve moves on the threaded post, simultaneously moving the mounting sleeve. This movement of the mounting sleeve causes multiple first anti-slip plates to expand outwards, which in turn moves multiple second anti-slip plates. The worker can control the number of turns of the Phillips head nut according to the required expansion size. This structure solves the slippage problem during automotive bolt installation and allows for adjustment of the limit angle, greatly improving practicality. Attached Figure Description

[0032] Example 1: This example provides a non-slip automotive bolt, comprising:

[0033] Bolt 1, with a hexagonal nut 2 fixedly installed at its top. An opening groove 5 is formed inside the bolt 1, and multiple mounting grooves 12 are formed on the inner side wall of the opening groove 5. Sliding grooves 13 are symmetrically formed on both sides of the interior of each mounting groove 12. Multiple first anti-slip plates 10 are rotatably mounted at the bottom of each mounting groove 12. A second mounting buckle 6 is fixedly installed at the top of each mounting groove 12. A second anti-slip plate 11 is provided above each of the first anti-slip plates 10, and a first mounting buckle 4 is fixedly installed at the bottom of each of the second anti-slip plates 11. The multiple second mounting buckles 6 are rotatably connected to the multiple first mounting buckles 4. A threaded post 7 is fixedly installed on the inner bottom surface of the opening groove 5. A threaded sleeve 8 is provided on the outer side wall of the threaded post 7, and a mounting sleeve 9 is provided on the outer side wall of the threaded sleeve 8. Multiple sets of adjustment components are all located within the opening groove 5. It is used to adjust the rotation angle of multiple first anti-slip plates 10. When the bolt 1 is installed, the worker puts the bolt 1 into the reserved mounting hole on the car. The worker first uses a vise to clamp the hexagonal nut 2 and rotates the bolt 1 to install it into the mounting hole. After ensuring that the installation is completed, the worker uses a cross-head screwdriver to align the cross-head screwdriver with the cross-head nut 3 and rotates the cross-head nut 3. While the cross-head nut 3 rotates, it drives the threaded sleeve 8 to move on the threaded post 7 and drives the mounting sleeve 9 to move synchronously. The movement of the mounting sleeve 9 drives multiple first anti-slip plates 10 to expand outward. The expansion of multiple first anti-slip plates 10 drives multiple second anti-slip plates 11 to move. The worker can control the number of turns of the cross-head nut 3 according to the required expansion size. This structure solves the problem of slippage during installation and can also realize the adjustment of the limit angle, greatly improving practicality.

[0034] Example 2: This example provides a non-slip automotive bolt, which, in addition to the technical solutions of the above examples, also has the following technical features.

[0035] The adjustment component includes a second mounting base 15, which is fixedly installed on one side of the first anti-slip plate 10. A push rod 16 is rotatably installed inside the second mounting base 15. A first mounting base 14 is fixedly installed on the outer wall of the mounting sleeve 9. One end of the push rod 16 is rotatably connected to the first mounting base 14, which allows for the simultaneous adjustment and movement of multiple first anti-slip plates 10 when the mounting sleeve 9 is moved by rotating the cross nut 3. This is simple and practical.

[0036] Example 3: This example provides a non-slip automotive bolt, which, in addition to the technical solutions of the above examples, also has the following technical features.

[0037] The threaded post 7 is provided with a cross nut 3 on top. The bottom surface of the cross nut 3 is fixedly connected to the top of the threaded sleeve 8. The bottom surface of the cross nut 3 is rotatably connected to the top of the mounting sleeve 9. This prevents the mounting sleeve 9 from interfering with the threaded sleeve 8 and getting stuck when the cross nut 3 is rotated to move the threaded sleeve 8 on the threaded post 7. This design is simple and practical.

[0038] Example 4: This example provides a non-slip automotive bolt, which, in addition to the technical solutions of the above examples, also has the following technical features.

[0039] The two sides of the multiple second anti-slip plates 11 are slidably installed in the multiple slide grooves 13, which makes it easier for the multiple first anti-slip plates 10 to expand outward and drive the multiple second anti-slip plates 11 to move, while the multiple second anti-slip plates 10 move outward and drive the multiple second anti-slip plates 11 to move. This is simple and practical.

[0040] Example 5: This example provides a non-slip automotive bolt, which, in addition to the technical solutions of the above examples, also has the following technical features.

[0041] The outer wall of the threaded column 7 is threadedly connected to the inner wall of the threaded sleeve 8. When the cross-shaped screwdriver is aligned with the cross-shaped nut 3 and the cross-shaped nut 3 is rotated, the cross-shaped nut 3 rotates and drives the threaded sleeve 8 to move on the threaded column 7, and simultaneously drives the mounting sleeve 9 to move synchronously. The thread design allows workers to control the number of turns of the cross-shaped nut 3 by expanding the size as needed, which is simple and practical.

[0042] Example 6: This example provides a non-slip automotive bolt, which, in addition to the technical solutions of the above examples, also has the following technical features.

[0043] The outer wall of the threaded sleeve 8 is rotatably connected to the inner wall of the mounting sleeve 9 to prevent the mounting sleeve 9 from interfering with the threaded sleeve 8 and getting stuck when the cross nut 3 is rotated to move the threaded sleeve 8 on the threaded post 7. This design is simple and practical.

[0044] Example 7: This example provides a non-slip automotive bolt, which, in addition to the technical solutions of the above examples, also has the following technical features.

[0045] The outer wall of bolt 1 is threaded, which makes it easy for workers to directly install bolt 1 into the corresponding mounting hole, making it simple and practical.

[0046] Working principle: When bolt 1 is being installed, the worker places bolt 1 into the pre-drilled mounting hole on the vehicle. The worker first uses a vise to clamp the hexagonal nut 2 and rotates bolt 1 to install it into the mounting hole. After ensuring the installation is complete, the worker uses a Phillips head screwdriver, aligns the screwdriver with the Phillips head nut 3, and rotates the Phillips head nut 3. As the Phillips head nut 3 rotates, it drives the threaded sleeve 8 to move on the threaded post 7, simultaneously driving the mounting sleeve 9 to move synchronously. The movement of the mounting sleeve 9 causes multiple first anti-slip plates 10 to expand outward, and the expansion of the multiple first anti-slip plates 10 causes multiple second anti-slip plates 11 to move. The worker can control the number of turns of the Phillips head nut 3 according to the required expansion size. This structure solves the problem of slippage during installation and also allows for adjustment of the limit angle, greatly improving practicality.
