Abstract
Description
Technical Field
[0001] This utility model relates to the field of steering ball pin technology, specifically a modular steering ball pin that is easy to disassemble. Background Technology
[0002] The steering ball joint is a key connecting component between the vehicle's suspension and steering systems. It connects the control arm (or lower control arm) and the steering knuckle, allowing for ball-joint movement (three-dimensional rotation) while transmitting driving, braking, and steering forces between the wheels and the vehicle body.
[0003] The ball joint head (ball head) is pressed vertically into the mounting hole of the steering knuckle or control arm with an interference fit (the hole diameter is slightly smaller than the ball head diameter). It is fixed by relying on the friction and plastic deformation of the metal surface. This installation method makes it difficult to disassemble the ball joint, which is not conducive to the maintenance of the ball joint. Utility Model Content
[0004] The purpose of this invention is to provide a modular steering ball pin that is easy to disassemble, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a modular steering ball pin that is easy to disassemble, comprising a lower mounting base, an upper mounting base, and a steering ball pin. The upper mounting base has four sets of mounting holes on its upper part and eight sets of locking holes communicating with the mounting holes inside the upper mounting base. The lower part of the upper mounting base is fixedly connected to four sets of mounting rods that mate with the mounting holes. A first lifting rod is slidably connected inside the mounting rod. Grooves are formed on both sides of the lower part of the first lifting rod. Connecting grooves are formed on both sides of the mounting rod. A locking block is slidably connected inside the connecting groove. A frustum with mating grooves is formed on the inner side of the locking block. A second lifting rod is fixedly connected to the upper part of the first lifting rod. Mounting grooves are formed on both sides of the upper part of the upper mounting base. A pull plate is fixedly connected to the upper part of the second lifting rod on the same side through the mounting groove.
[0006] Preferably, the mounting rod has control slots on both sides that communicate with the connecting slot. A sliding rod is fixedly connected inside the control slot. A connecting piece is slidably connected to the outside of the sliding rod. The connecting piece is fixedly connected to the locking block. A first spring is fixedly connected between the connecting piece and the inner wall of the control slot. The first spring is sleeved on the outside of the sliding rod.
[0007] Preferably, a second spring is fixedly connected between the pull plate and the mounting groove, and the second spring is sleeved on the outside of the second lifting rod.
[0008] Preferably, the lower part of the pull plate is fixedly connected with two sets of threaded rings, the threaded rings are sleeved on the outside of the second lifting rod, the upper mounting base has an embedding groove directly opposite the threaded rings, and a locking piece is threadedly connected to the outside of the threaded rings.
[0009] Preferably, the upper mounting base has a connecting groove communicating with the mounting groove. A rotating shaft is rotatably connected inside the connecting groove. A baffle is fixedly connected to the outside of the rotating shaft. A torsion spring is fixedly connected to the baffle and the inside of the connecting groove. The torsion spring is sleeved on the outside of the rotating shaft.
[0010] Preferably, the steering ball pin is rotatably connected to the lower mounting base and the upper mounting base, and the steering ball pin is sleeved inside the upper mounting base.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. This utility model uses downward pressure to pull the plate, causing the first lifting rod to drive the second lifting rod downward, so that the groove is aligned with the truncated cone. The first spring pulls the connecting piece along the sliding rod, which can drive the locking block to move inward, allowing the mounting rod at the lower part of the upper mounting seat to be inserted into the mounting hole. When the pull plate is released, the second spring pushes the pull plate upward, causing the groove to disengage from the truncated cone. This causes the locking block to move to both sides along the connecting groove and be inserted into the locking hole, thus realizing the connection between the upper and lower mounting seats. This facilitates the disassembly and assembly of the steering ball pin and improves the maintenance convenience of the steering ball pin.
[0013] 2. This utility model also uses a rotating locking piece to move the locking piece downwards and fit tightly against the inside of the mounting groove, thereby locking the pull plate and preventing the pull plate from driving the first and second lifting rods downwards. This ensures that the locking block is always inside the locking hole and prevents external accidental contact with the equipment from causing the locking to become unreliable.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-4 This utility model provides a technical solution: a modular steering ball pin that is easy to disassemble, including a lower mounting base 1, an upper mounting base 2, and a steering ball pin 3. The upper mounting base 2 has four sets of mounting holes 4 on its upper part, and eight sets of locking holes 5 communicating with the mounting holes 4 inside the upper mounting base 2. Four sets of mounting rods 6 that mate with the mounting holes 4 are fixedly welded to the lower part of the upper mounting base 2. The connection between the upper mounting base 2 and the lower mounting base 1 is achieved by inserting the mounting rods 6 at the lower part of the upper mounting base 2 into the mounting holes 4. A first lifting rod 7 is slidably installed inside the mounting rod 6. Grooves 8 are formed on both sides of the lower part of the first lifting rod 7, and connecting grooves 9 are formed on both sides of the mounting rod 6. The connecting grooves 9 allow for sliding... A locking block 10 is installed, and a frustum 11 with a matching groove 8 is opened on the inner side of the locking block 10. The first lifting rod 7 moves upward, causing the frustum 11 to disengage from the groove 8, and the locking block 10 moves to both sides along the connecting groove 9. The locking block 10 is inserted into the locking hole 5 to lock the upper mounting seat 2. A second lifting rod 16 is fixedly welded to the upper part of the first lifting rod 7. Mounting grooves 22 are opened on both sides of the upper part of the upper mounting seat 2. A pull plate 17 is fixedly welded to the upper part of the second lifting rod 16 on the same side through the mounting groove 22. The pull plate 17 drives the first lifting rods 7 on both sides to move, thereby controlling the up and down movement of the second lifting rod 16, so as to realize the alignment and disengagement of the groove 8 and the frustum 11.
[0021] Control grooves 12, communicating with the connecting grooves 9, are provided on both sides of the mounting rod 6. A sliding rod 14 is fixedly welded inside the control groove 12. A connecting piece 13 is slidably mounted on the outside of the sliding rod 14. The connecting piece 13 is fixedly welded to the locking block 10. A first spring 15 is fixedly welded between the connecting piece 13 and the inner wall of the control groove 12. The first spring 15 is sleeved on the outside of the sliding rod 14. When the groove 8 is aligned with the frustum 11, the first spring 15 pulls the connecting piece 13 to move along the sliding rod 14, which can drive the locking block 10 to move inward. The second spring 18 is fixedly welded between the pull plate 17 and the mounting groove 22. The second spring 18 is sleeved on the outside of the second lifting rod 16. The second spring 18 pushes the pull plate 17 downward to ensure that the groove 8 disengages from the frustum 11 under normal extension and retraction, so that the locking block 10 is always in the locking hole 5. Two sets of threaded rings 19 are fixedly welded to the lower part of the pull plate 17. The threaded rings 19 are sleeved on the outside of the second lifting rod 16 and inside the upper mounting base 2. An insert groove 20 is provided directly opposite the threaded ring 19. A locking piece 21 is threadedly installed on the outer side of the threaded ring 19. By rotating the locking piece 21, the locking piece 21 moves downward and fits tightly against the inside of the mounting groove 22, thereby locking the pull plate 17 and preventing the pull plate 17 from driving the first lifting rod 7 and the second lifting rod 16 to move downward. The upper mounting base 2 has a connecting groove 23 on its upper part that communicates with the mounting groove 22. A rotating shaft 24 is rotatably connected inside the connecting groove 23. A baffle 25 is fixedly welded to the outside of the rotating shaft 24 to prevent the shaft from moving downward. A torsion spring 26 is fixedly welded inside the plate 25 and the connecting groove 23. The torsion spring 26 is sleeved on the outside of the rotating shaft 24. The torsion spring 26 pulls the rotating shaft 24, causing the baffle 25 to rotate to the horizontal direction, blocking the mounting groove 22 and preventing external objects from damaging the pulling plate 17. The steering ball pin 3 is rotatably installed inside the lower mounting seat 1 and the upper mounting seat 2. The steering ball pin 3 is sleeved inside the upper mounting seat 2. When the upper mounting seat 2 and the lower mounting seat 1 are separated, the steering ball pin 3 can be taken out along the upper mounting seat 2, which allows for quick removal of the steering ball pin 3.
[0022] Working principle: When in use, by pressing down on the pull plate 17, the first lifting rod 7 drives the second lifting rod 16 to move downward, so that the groove 8 is aligned with the truncated cone 11. The first spring 15 pulls the connecting piece 13 along the sliding rod 14, which can drive the locking block 10 to move inward, so that the mounting rod 6 at the lower part of the upper mounting seat 2 can be inserted into the mounting hole 4. When the pull plate 17 is released, the second spring 18 pushes the pull plate 17 to move upward, so that the groove 8 is disengaged from the truncated cone 11, and the locking block 10 moves to both sides along the connecting groove 9. The locking block 10 is inserted into the locking hole 5, realizing the connection between the upper mounting seat 2 and the lower mounting seat 1. By rotating the locking piece 21, the locking piece 21 moves downward and fits tightly against the inside of the mounting groove 22, thereby locking the pull plate 17 and preventing the pull plate 17 from driving the first lifting rod 7 and the second lifting rod 16 to move downward, ensuring that the locking block 10 is always inside the locking hole 5.
