DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0024] refer to Figures 1 to 6 The utility model provides a ball head for a high-durability automobile steering system, comprising: a ball seat 1, a placement groove 7 is provided on the top of the ball seat 1, a placement seat 8 is provided inside the placement groove 7, a ball groove 19 is provided on the top of the placement seat 8, and the placement seat 8 is connected to the placement groove 7 through a buffer device 14. A ball head 9 is placed inside the ball groove 19, and the top of the ball head 9 is connected to the ball rod 2 through a ball neck, and a connecting hole 3 is provided on the top of the ball rod 2, and the outer wall of the ball rod 2 is movably connected to a protective rubber sleeve 5. The bottom of the protective rubber sleeve 5 is rotatably connected to a rotating groove 10, and the rotating groove 10 is also arranged on the top of the ball seat 1. A straight pull rod 6 is provided on one side of the ball seat 1, and the ball seat 1 and the straight pull rod 6 are integrally formed, and a plurality of rotating holes are provided on the inner wall of the ball groove 19, and the inner wall of the rotating hole is rotatably connected to a rotating ball 12.

[0025] It should be noted that when the protective rubber sleeve 5 is connected to the rotating groove 10, the bottom of the protective rubber sleeve 5 is located above the bottom of the rotating groove 10. When the ball head 9 rotates, the ball rod 2 and the protective rubber sleeve 5 connected thereto can be driven to rotate synchronously, and the protective rubber sleeve 5 is rotationally connected to the rotating groove 10, so that the top of the ball seat 1 can always be in the protective rubber sleeve 5, thereby improving the protective effect of the protective rubber sleeve 5, and preventing the protective rubber sleeve 5 from being compressed during use. The gap between the protective rubber sleeve 5 and the ball seat 1 can prevent mud and sand from easily entering the interior of the tie rod ball head 9 assembly through the gap, resulting in a shortened service life of the tie rod ball head 9 assembly. By setting the placement seat 8, the ball head 9 can be in contact with the placement seat 8, reducing the load on the ball seat 1 and increasing the service life of the device.

[0026] In the embodiments of the present invention, reference is made to Figure 3 As shown, the inner wall of the ball groove 19 is provided with a plurality of rotating holes, and the inner walls of the rotating holes are rotatably connected to the rotating ball 12 .

[0027] It should be noted that by providing the rotating ball 12, the friction between the ball head 9 and the inner wall of the ball groove 19 can be reduced, thereby increasing the service life of the device.

[0028] In the embodiments of the present invention, reference is made to Figure 2 , Figure 5 As shown, a lower limit groove 17 is provided at the bottom of the protective rubber sleeve 5 , and the lower limit groove 17 is rotatably connected to a limit ring 11 , and the limit ring 11 is installed at the bottom end of the inner part of the rotating groove 10 .

[0029] It should be noted that by providing the lower limit groove 17 , the cooperation between the lower limit groove 17 and the limit ring 11 can improve the sealing performance of the protective rubber sleeve 5 on the one hand, and improve the stability of the protective rubber sleeve 5 during rotation on the other hand.

[0030] In the embodiments of the present invention, reference is made to Figure 1 As shown, the outer surface of the club 2 is provided with an external thread 4, and the external thread 4 is threadedly connected to the inner wall of the protective rubber sleeve 5.

[0031] It should be noted that: by providing the external thread 4, it is convenient to move the protective rubber sleeve 5 up and down, thereby improving the applicability of the device.

[0032] In the embodiments of the present invention, reference is made to Figure 4 As shown, the buffer device 14 includes a plurality of telescopic rods 15, the outer surface of the telescopic rods 15 is sleeved with a return spring 16, and the top and bottom of the telescopic rods 15 are respectively connected to the bottom of the placement seat 8 and the bottom end of the placement groove 7.

[0033] It should be noted that by providing the telescopic rod 15 and the return spring 16 , the placement seat 8 can be buffered, and when subjected to force, the vibration of the placement seat 8 can be reduced, thereby reducing damage to the ball head 9.

[0034] In the embodiments of the present invention, reference is made to Figure 4 , Figure 6 As shown, the inner wall of the placement groove 7 is provided with a plurality of sliding grooves 13 , and the sliding grooves 13 are slidably connected to sliders 18 , and the sliders 18 are arranged on the outer surface of the placement seat 8 .

[0035] It should be noted that: by providing the sliding groove 13 , the sliding groove 13 can limit the position of the slider 18 , thereby improving the stability of the placement seat 8 moving up and down.

[0036] The working principle of the ball head 9 of the high-durability automobile steering system provided by the utility model is as follows:

[0037] When the ball head 9 rotates, the club 2 and the protective rubber sleeve 5 connected thereto can be driven to rotate synchronously, and the protective rubber sleeve 5 is rotationally connected to the rotating groove 10 and can rotate synchronously therewith, so that the upper part of the ball seat 1 is always inside the protective rubber sleeve 5, thereby improving the protective effect of the protective rubber sleeve 5. When the club 2 swings, it can be completed by the deformation of the relatively soft and elastic protective rubber sleeve 5. At this time, since the bottom of the protective rubber sleeve 5 is always restricted in the rotating groove 10 and does not fall out of the rotating groove 10, the sealing effect can still be ensured at all times, and the effect is remarkable.

[0038] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0039] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
