TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile parts, especially relates to a ball head dust cover. BACKGROUND

[0002] The ball head dust cover is a key component for protecting the ball head (such as a steering ball head, a suspension ball head, etc.) in an automobile chassis system, and the main function of the ball head dust cover is to prevent dust, mud and other foreign matters from entering the ball head, to avoid the ball head from being abraded or disabled due to pollution, and the ball head dust cover can also prevent the lubricating grease inside the ball head from being lost, so as to ensure the smooth rotation of the ball head.

[0003] The existing ball head dust cover has fixed specifications and limited dustproof area, and the dustproof area of the dust cover cannot be adjusted according to the use requirement, and therefore, the ball head dust cover is provided. SUMMARY

[0004] The utility model discloses a ball head dust cover which is provided to solve the problems mentioned in the background.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0006] A ball head dust cover, comprising a ball head seat, a ball head pin and a dust cover body, the lower end of the dust cover body is connected with the ball head seat, the upper end of the dust cover body is connected with a ring-shaped moving sleeve, the moving sleeve is slidingly connected with the rod part of the ball head pin, and a threaded torsion bar is arranged on the moving sleeve to fix the moving sleeve on the rod part of the ball head pin.

[0007] Preferably, a ring-shaped groove is formed in the inner ring surface of the moving sleeve, and a ring of sealing rings is arranged in the ring-shaped groove.

[0008] Preferably, the lower end of the dust cover body is connected with the ball head seat by a snap ring.

[0009] Preferably, the dust cover body is made of neoprene material.

[0010] Preferably, the dust cover body has a folding structure.

[0011] Compared with the prior art, the utility model has the advantages that:

[0012] The moving sleeve is arranged on the existing dust cover body, and the moving sleeve is connected with the rod part of the ball head pin, and the fixed position of the moving sleeve on the ball head pin can be adjusted arbitrarily, so that the protection area of the dust cover body on the ball head is variable, and the use range of the device is increased.

[0017] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0018] Referring to Figures 1-3 Fig. 1, a ball head dust cover includes a ball head seat 1, a ball head pin 2 and a dust cover body 4, the lower end of the dust cover body 4 is connected with the ball head seat 1, the upper end of the dust cover body 4 is connected with an annular moving sleeve 3, the moving sleeve 3 is slidingly connected with the rod part of the ball head pin 2, and a threaded torsion bar 5 is arranged on the moving sleeve 3 for fixing the moving sleeve 3 on the rod part of the ball head pin 2.

[0019] An annular groove 6 is formed on the inner annular surface of the moving sleeve 3, and a ring of sealing rings is arranged in the annular groove 6.

[0020] The lower end of the dust cover body 4 is connected with the ball head seat 1 by a snap ring.

[0021] The dust cover body 4 is made of neoprene rubber material, and the neoprene rubber has excellent aging resistance (weather resistance, ozone resistance and heat resistance) and excellent oil resistance and solvent resistance, which is suitable for the working environment of the dust cover body 4.

[0022] The dust cover body 4 has a folded structure, so that it can freely stretch and fold when the ball head moves, and the protection area of the dust cover body 4 can be conveniently adjusted.

[0023] Working process and principle:

[0024] In use, first, the moving sleeve 3 is sleeved on the rod part of the ball head pin 2, then the lower end of the dust cover body 4 is connected on the ball head seat 1 through the snap ring, according to different working states of the ball head, the moving sleeve 3 can be slid, then the screw torsion bar 5 is rotated to fix the moving sleeve 3 on the rod part of the ball head pin 2, namely, the installation is completed, the ball head is protected by the dust cover body 4, dust or moisture is avoided from entering, since the fixed position of the moving sleeve 3 can be adjusted at will, the protection area of the ball head by the dust cover body 4 has variability, the use range of the device is increased.

[0025] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
