Description

Technical Field

[0001] This utility model relates to the field of ball head bolt technology, specifically a ball head bolt for automotive control arms that is easy to replace. Background Technology

[0002] A ball head bolt is a specially designed fastener with a spherical head. This design allows it to accommodate multi-directional movement and angle adjustment, providing greater flexibility and fit when connecting. The shank of the ball head bolt has external threads for mating with nuts or other internally threaded components to achieve a fastening connection.

[0003] Ball head bolts installed on vehicles or outdoor storage equipment in coastal areas will come into prolonged contact with moisture in the air during long-term use. When the ball head bolts are in contact with moisture for a long time, a rust layer will gradually form on the surface of the thread on the ball head bolt.

[0004] When the rust layer on the surface of the ball head bolt reaches a certain thickness, the force required for the user to tighten the ball head bolt will also increase, making it more difficult to replace the ball head bolt.

[0005] In view of this, we propose a ball head bolt for automotive control arms that is easy to replace. Utility Model Content

[0006] The purpose of this invention is to provide a ball head bolt for automotive control arms that is easy to replace, in order to solve the problem of difficult replacement mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An easily replaceable ball head bolt for automotive control arms, comprising a ball head bolt, and further comprising:

[0009] Multiple first through slots are formed on the periphery of the ball head bolt. Multiple sliders are slidably connected in the multiple first through slots. Multiple tension spring slots are formed on the side of the multiple sliders that are close to each other. Multiple first tension springs are fixedly connected in the multiple tension spring slots, and one end of each of the multiple first tension springs is fixed to the inner wall of the multiple first through slots.

[0010] An extrusion assembly, located within a ball head bolt, is used to secure a plurality of sliders;

[0011] The threaded groove is formed on the lower half of the ball head bolt and on the side of the plurality of sliders that are far apart from each other;

[0012] The second through groove is formed inside the ball head bolt. Multiple oil outlet grooves are formed on the inner wall of the second through groove, and the multiple oil outlet grooves are respectively connected to multiple first through grooves. An oil filling port connected to the outside is formed on the inner wall of the second through groove, and a plug is inserted into the oil filling port.

[0013] The design incorporates a first through groove and a slider, ensuring the slider can slide within the first through groove. A pressing assembly allows the user to secure multiple sliders. A threaded groove allows the user to install the ball head bolt into the mounting hole. First tension springs ensure that when the pressing assembly releases the sliders, they pull them closer together along the first through grooves, reducing the contact area between the lower half of the ball head bolt and the mounting hole, simplifying replacement. An oil outlet groove, a second through groove, and an oil inlet allow the user to inject lubricating oil into the second through groove, which then flows into multiple oil outlet grooves and finally into the first through grooves, allowing the lubricating oil to enter the mounting hole, further simplifying ball head bolt replacement. A plug ensures the oil inlet is blocked.

[0014] This solves the problem that when the rust layer on the surface of the ball head bolt reaches a certain thickness, the force required for the user to tighten the ball head bolt also increases, making it more difficult to replace the ball head bolt.

[0015] Preferably, the extrusion assembly includes:

[0016] The first slide groove is formed inside the ball head bolt and is connected to multiple first through grooves. A pressing block is slidably connected inside the first slide groove, and the pressing block abuts against multiple sliders.

[0017] The second slide groove is formed on the inner wall of the first slide groove. A slide rod is slidably connected in the second slide groove, and the bottom end of the slide rod extends into the first slide groove and is fixed to the extrusion block. The top end of the slide rod is fixedly connected to a second tension spring that is fixed to the inner wall of the second slide groove. An extrusion groove is formed on the slide rod.

[0018] The third slide groove is formed on the inner wall of the second slide groove and is connected to the outside. A pressing rod is slidably connected in the third slide groove, and one end of the pressing rod extends into the pressing groove and is inserted into the pressing groove. The other end of the pressing rod extends to the outside and is slidably connected to the ball head bolt.

[0019] A limiting component is located inside the extrusion rod and is used to fix the extrusion rod.

[0020] This ensures that the user can move multiple sliders and fix each slider in a suitable position within a number of first through slots.

[0021] Preferably, the limiting component includes:

[0022] A socket, wherein the socket is formed inside the ball head bolt and is connected to the outside;

[0023] The fourth slide groove is formed inside the extrusion rod and is connected to the outside. A plug rod is slidably connected inside the fourth slide groove, and the bottom end of the plug rod extends into the plug hole and is inserted into the plug hole. The top end of the plug rod extends to the outside.

[0024] A limiting block is fixedly connected to the periphery of the insertion rod and is slidably connected to the fourth sliding groove. A spring is fixedly connected to the top surface of the limiting block, and the top end of the spring is fixed to the inner wall of the fourth sliding groove.

[0025] Ensure that the user can fix the extrusion rod in the third groove and prevent it from moving.

[0026] Preferably, the tip of the insertion rod is made of rubber.

[0027] Ensure that the user's hand does not slip when pulling the lever.

[0028] Preferably, one end of the slide rod is slidably connected to the first slide groove.

[0029] Ensure that one end of the slide bar can slide normally within the first slide groove.

[0030] Preferably, the bottom surface of the extrusion block is inclined.

[0031] Ensure that the extrusion block can drive multiple sliders away from each other.

[0032] Preferably, one end of the compression rod is inclined.

[0033] Ensure that the user can squeeze one end of the lever to squeeze the squeeze groove, causing the slide bar to move downwards.

[0034] Compared with the prior art, the beneficial effects of this utility model are as follows: This easily replaceable ball head bolt for automotive control arms, through the provided first through groove and slider, ensures that the slider can slide within the first through groove; through the provided extrusion assembly, it ensures that the user can fix multiple sliders through the extrusion assembly; through the provided threaded groove, it allows the user to install the ball head bolt into the mounting hole through the threaded groove; through the provided first tension spring, it ensures that when the extrusion assembly releases the fixing of multiple sliders, the multiple first tension springs will respectively pull the multiple sliders closer to each other along the multiple first through grooves, reducing the contact surface between the lower half of the ball head bolt and the mounting hole. The design reduces the difficulty for users to replace ball head bolts. Through the inclusion of an oil outlet groove, a second through groove, and an oil inlet, users can inject lubricating oil into the second through groove via the oil inlet. The lubricating oil then flows into multiple oil outlet grooves and subsequently into multiple first through grooves, allowing the lubricating oil to enter the mounting hole. This further reduces the difficulty of replacing ball head bolts. The included plug ensures that the oil inlet is blocked, solving the problem that when the rust layer on the ball head bolt's screw surface reaches a certain thickness, the force required to tighten the bolt increases, making replacement more difficult.

[0047] Ball head bolts installed on vehicles or outdoor storage equipment in coastal areas will come into prolonged contact with moisture in the air during long-term use. When the ball head bolts are in contact with moisture for a long time, a rust layer will gradually form on the surface of the thread on the ball head bolt.

[0048] When the rust layer on the surface of the ball head bolt reaches a certain thickness, the force required for the user to tighten the ball head bolt will also increase, making it more difficult to replace the ball head bolt.

[0049] Please see Figures 1-7 As shown, this utility model provides a technical solution:

[0050] A replaceable ball head bolt for automotive control arms, comprising a ball head bolt 1, and further comprising:

[0051] Multiple first through slots 2 are formed on the periphery of ball head bolt 1. Multiple sliders 3 are slidably connected in the multiple first through slots 2. Multiple tension spring slots 4 are formed on the side of the multiple sliders 3 that are close to each other. Multiple first tension springs 5 ​​are fixedly connected in the multiple tension spring slots 4, and one end of the multiple first tension springs 5 ​​is fixed to the inner wall of the multiple first through slots 2.

[0052] An extrusion assembly is located inside the ball head bolt 1 and is used to fix multiple sliders 3;

[0053] The threaded groove 6 is formed on the lower half of the ball head bolt 1 and on the side where the multiple sliders 3 are far apart from each other.

[0054] The second through groove 8 is opened inside the ball head bolt 1. Multiple oil outlet grooves 7 are opened on the inner wall of the second through groove 8, and the multiple oil outlet grooves 7 are respectively connected to multiple first through grooves 2. An oil filling port 9 connected to the outside is opened on the inner wall of the second through groove 8, and a plug 10 is inserted into the oil filling port 9.

[0055] Specifically, the user releases the fixation of multiple sliders 3 by squeezing the assembly, causing each slider 3 to be pulled by multiple first tension springs 5 ​​and move closer to each other along multiple first through grooves 2. When the multiple sliders 3 move closer to each other to a suitable position, the contact area between the ball head bolt 1 and the mounting hole is reduced, initially reducing the difficulty for the user to replace the ball head bolt 1. Then, the user pulls the plug 10 by hand to pull the plug 10 out of the oil inlet 9. The user then injects lubricating oil into the oil inlet 9, allowing the lubricating oil to flow through the second through groove 8 into multiple oil outlet grooves 7, and then into multiple first through grooves 2 through multiple oil outlet grooves 7, flowing to the space between the ball head bolt 1 and the mounting hole, further reducing the difficulty for the user to replace the ball head bolt 1.

[0056] Preferably, it ensures that users can replace ball head bolt 1 with less effort and makes it easier to replace ball head bolt 1 after replacement.

[0057] In this embodiment, the extrusion assembly includes:

[0058] The first slide groove 11 is opened in the ball head bolt 1 and is connected to multiple first through grooves 2. The first slide groove 11 is slidably connected to the extrusion block 12, and the extrusion block 12 abuts against multiple sliders 3.

[0059] The second slide groove 13 is formed on the inner wall of the first slide groove 11. A slide rod 14 is slidably connected in the second slide groove 13, and the bottom end of the slide rod 14 extends into the first slide groove 11 and is fixed to the extrusion block 12. The top end of the slide rod 14 is fixedly connected to a second tension spring 15 that is fixed to the inner wall of the second slide groove 13. An extrusion groove 16 is formed on the slide rod 14.

[0060] The third slide groove 17 is formed on the inner wall of the second slide groove 13 and is connected to the outside. A pressing rod 18 is slidably connected in the third slide groove 17. One end of the pressing rod 18 extends into the pressing groove 16 and is inserted into the pressing groove 16. The other end of the pressing rod 18 extends to the outside and is slidably connected to the ball head bolt 1.

[0061] A limiting component is located inside the extrusion rod 18 and is used to fix the extrusion rod 18.

[0062] Specifically, when the user needs to release the fixation of multiple sliders 3, the user first releases the fixation of the extrusion rod 18 through the limiting component. Then, the user pulls the extrusion rod 18 by hand, allowing one end of the extrusion rod 18 to enter the third slide groove 17 from the extrusion groove 16. At this time, the fixation of the slide rod 14 is released. When the fixation of the slide rod 14 is released, the slide rod 14 will be pulled by the second tension spring 15 and move upward along the second slide groove 13, causing the slide rod 14 to drive the extrusion block 12 to move upward along the first slide groove 11, thus releasing the fixation of the extrusion block 12 to the multiple sliders 3. When the user needs to fix the multiple sliders 3, the user pushes the extrusion rod 18 by hand. The extrusion rod 18 is used to press one end of the extrusion groove 16. When the extrusion rod 18 presses the inner wall of the extrusion groove 16, the slide rod 14 will drive the extrusion block 12 to move downward along the first slide groove 11 and stretch the second tension spring 15. When the extrusion block 12 moves downward, the bottom surface of the extrusion block 12 will press multiple sliders 3 respectively, causing the multiple sliders 3 to move away from each other along multiple first through grooves 2 and stretching multiple first tension springs 5 ​​respectively. When the multiple sliders 3 move away from each other to a position where they cannot move, one end of the extrusion rod 18 will be inserted into the extrusion groove 16 from the third slide groove 17. Then the user fixes the extrusion rod 18 by using the limiting component.

[0063] Preferably, the user can move multiple sliders 3 and fix the multiple sliders 3 in appropriate positions within multiple first through slots 2.

[0064] In this embodiment, the limiting component includes:

[0065] The socket 23 is located inside the ball head bolt 1 and is connected to the outside.

[0066] The fourth slide groove 19 is opened inside the extrusion rod 18 and is connected to the outside. The insertion rod 20 is slidably connected inside the fourth slide groove 19, and the bottom end of the insertion rod 20 extends into the insertion hole 23 and is inserted into the insertion hole 23. The top end of the insertion rod 20 extends to the outside.

[0067] The limiting block 21 is fixedly connected to the periphery of the insertion rod 20 and is slidably connected to the fourth slide groove 19. A spring 22 is fixedly connected to the top surface of the limiting block 21, and the top end of the spring 22 is fixed to the inner wall of the fourth slide groove 19.

[0068] Specifically, when the user needs to pull the compression rod 18, the user pulls the insertion rod 20 by hand, causing the bottom end of the insertion rod 20 to move from the insertion hole 23 to the outside. At the same time, the insertion rod 20 will drive the limiting block 21 to move within the fourth slide groove 19 and compress the spring 22. At this time, the compression rod 18 is released. Then, the user pulls the compression rod 18 by hand. When the user needs to fix the compression rod 18, the user releases the hand that pulled the insertion rod 20, allowing the limiting block 21 to be subjected to the rebound force of the spring 22 and move downward along the fourth slide groove 19, causing the bottom end of the insertion rod 20 to be inserted from the outside into the insertion hole 23, fixing the compression rod 18 and preventing the compression rod 18 from moving due to external influences.

[0069] Preferably, it ensures that the user can fix the compression rod 18 in the third slide groove 17 and prevent it from moving.

[0070] In this embodiment, the top end of the insertion rod 20 is made of rubber.

[0071] Specifically, when the user pulls the plug rod 20 by hand, the rubber material at the top of the plug rod 20 can increase the friction between the user's hand and the top of the plug rod 20.

[0072] Preferably, it prevents the user from slipping their hand when pulling the plug 20.

[0073] In this embodiment, one end of the slide rod 14 is slidably connected to the first slide groove 11.

[0074] Specifically, when the slide bar 14 slides, one end of the slide bar 14 can slide along the first slide groove 11.

[0075] Preferably, it is ensured that one end of the slide bar 14 can slide normally within the first slide groove 11.

[0076] In this embodiment, the bottom surface of the extrusion block 12 is inclined.

[0077] Specifically, when the extrusion block 12 moves downward, the bottom surface of the extrusion block 12 presses against the multiple sliders 3, and the multiple sliders 3 will move away from each other along the multiple first through slots 2 respectively.

[0078] Preferably, the extrusion block 12 is designed to drive the multiple sliders 3 away from each other.

[0079] In this embodiment, one end of the compression rod 18 is inclined.

[0080] Specifically, when the extrusion rod 18 moves, one end of the extrusion rod 18 can press the inner wall of the extrusion groove 16, causing the extrusion groove 16 to drive the slide rod 14 to move downward.

[0081] Preferably, the user can squeeze one end of the lever 18 to squeeze the squeezing groove 16, causing the slide bar 14 to move downward.

[0082] In this embodiment, the user manually pulls the insert rod 20, moving its bottom end from the insertion hole 23 to the outside. Simultaneously, the insert rod 20 moves the limiting block 21 within the fourth sliding groove 19, compressing the spring 22. At this point, the fixing of the compression rod 18 is released. The user then manually pulls the compression rod 18, moving one end of it from the compression groove 16 into the third sliding groove 17. At this point, the fixing of the slide rod 14 is released. When the fixing of the slide rod 14 is released, the slide rod 14 is subjected to the tension of the second tension spring 15. The function is to move upward along the second slide groove 13, causing the slide rod 14 to drive the extrusion block 12 upward along the first slide groove 11, thus releasing the extrusion block 12 from fixing the multiple sliders 3. This allows the multiple sliders 3 to be subjected to the tension of the multiple first tension springs 5, causing them to move closer to each other along the multiple first through grooves 2. When the multiple sliders 3 are close to each other in a suitable position, the contact area between the ball head bolt 1 and the mounting hole is reduced. Then, the user pulls the plug 10 by hand to remove it from the oil inlet 9. The user then injects lubricating oil into the oil inlet 9, allowing the lubricating oil to flow through the second through groove 8 into the multiple sliders. The oil flows into multiple first through grooves 2 through multiple outlet grooves 7, and flows between the ball head bolt 1 and the mounting hole, ensuring that the user can replace the ball head bolt 1 more easily and effortlessly. After replacement, the user pushes the extrusion rod 18 by hand, so that one end of the extrusion rod 18 presses against the extrusion groove 16. When one end of the extrusion rod 18 presses against the inner wall of the extrusion groove 16, the slide rod 14 will drive the extrusion block 12 to move downward along the first slide groove 11 and stretch the second tension spring 15. When the extrusion block 12 moves downward, the bottom surface of the extrusion block 12 will extrude oil into the groove. Press down multiple sliders 3, causing them to move away from each other along multiple first through grooves 2, and stretch multiple first tension springs 5. When the sliders 3 are moved away from each other to a position where they cannot move, one end of the pressing rod 18 will be inserted into the pressing groove 16 from the third slide groove 17. When one end of the pressing rod 18 is inserted into the pressing groove 16, the limiting block 21 will be subjected to the rebound force of the spring 22 and move downward along the fourth slide groove 19, causing the bottom end of the insert rod 20 to be inserted into the insertion hole 23 from the outside, fixing the pressing rod 18 and preventing the pressing rod 18 from moving due to external influences.

[0083] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
