Description

Technical Field

[0001] This utility model relates to the field of wheel hub dust cover technology, specifically a quick-change front axle wheel hub dust cover structure. Background Technology

[0002] A dust cover is a ring-shaped cover, usually made of a thin metal sheet, fixed to one of the bearing rings or washers and extending toward the other ring or washer, covering the internal space of the bearing without contacting the other ring or washer. A wheel hub dust cover generally refers to a cover installed at the center hole of a car wheel hub. Its main function is to prevent mud, rainwater, and brake dust from entering the wheel hub bearing, reduce corrosion of metal parts, and cover the center hole of the wheel hub to improve the overall visual effect.

[0003] Traditional wheel dust covers require thorough cleaning of the wheel surface with a clean, damp cloth or detergent to remove dust, oil, and debris, ensuring a tight fit. They are then installed on the outside of the wheel with multiple bolts, ensuring they are flush against the wheel's edge.

[0004] Traditional wheel dust covers require workers to hold the cover and place it over the outside of the wheel hub before inserting and tightening multiple bolts one by one using tools. The installation process is cumbersome and inconvenient to remove. Utility Model Content

[0005] The purpose of this utility model is to provide a quick-change front axle hub dust cover structure to solve the problems mentioned in the background art, such as the cumbersome installation and inconvenient removal of the dust cover.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-change front axle hub dust cover structure, including a mounting base and a dust cover attached to the surface of the mounting base. The mounting base around the dust cover has an annular groove, and the annular groove has an insertion port. A connecting ring is fitted on the outer wall of the dust cover. A connecting rod that can be inserted into the annular groove is installed at the bottom end of the connecting ring, and an abutment block that matches the opening of the insertion port is provided on the connecting rod. By rotating the connecting ring, the abutment block can be engaged with the annular groove.

[0007] The dust cover has a ring installed at its top, a screw is provided inside the ring, a rotating rail is installed at the top of the screw, a rotating ring is fitted on the outer wall of the rotating rail, a bolt is installed at the top of the rotating rail, and a mounting bracket is provided on the outer wall of the rotating ring.

[0008] Preferably, the bottom end of the mounting bracket extends to the top end of the connecting ring, and the mounting bracket and the connecting ring are connected to each other.

[0009] Preferably, the internal space of the annular groove is annular, and the annular groove can accommodate the movement of the abutment block inside it.

[0010] Preferably, the bottom end of the connecting rod passes through the mounting base and the dust cover in sequence and extends into the interior of the annular groove, and the connecting rod and the connecting ring are connected to each other by threads.

[0011] Preferably, the insert ring has internal threads, and the screw and the insert ring are connected by threads.

[0012] Preferably, the inner diameter of the rotating ring is larger than the outer diameter of the rotating rail, and the rotating ring can rotate on the outer wall of the rotating rail.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: Rotating the bolt drives the rotating rail and screw to rotate, causing the screw to unscrew from the inside of the insert ring. The screw drives the rotating rail to rise, which in turn drives the rotating ring to move the mounting bracket. The mounting bracket then drives the connecting ring to move upward, which in turn drives the connecting rod to move the abutment block. This causes the abutment block to press tightly against the inner wall above the ring groove. When the height reaches its maximum value, the dust cover can be tightened. Rotating the bolt in the opposite direction separates the dust cover from the mounting base. This structure allows for the fixing and disassembly of the dust cover with the rotation of a single bolt, making installation and removal relatively simple. Attached Figure Description

[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] Example 1: A quick-change front axle hub dust cover structure includes a mounting base 1 and a dust cover 7 attached to the surface of the mounting base 1. The mounting base 1 around the dust cover 7 has an annular groove 8, and the annular groove 8 has an insertion port 13. The outer wall of the dust cover 7 is fitted with a connecting ring 2. The bottom end of the connecting ring 2 is fitted with a connecting rod 3 that can be inserted into the annular groove 8. The connecting rod 3 has an abutment block 9 that matches the opening of the insertion port 13. By rotating the connecting ring 2, the abutment block 9 can be engaged with the annular groove 8.

[0021] The top of the dust cover 7 is fitted with a ring 5, the inside of the ring 5 is fitted with a screw 10, and the top of the screw 10 is fitted with a rotating rail 12. The outer wall of the rotating rail 12 is fitted with a rotating ring 11, and the top of the rotating rail 12 is fitted with a bolt 6. The outer wall of the rotating ring 11 is fitted with a mounting bracket 4.

[0022] The bottom end of the mounting bracket 4 extends to the top end of the connecting ring 2, and the mounting bracket 4 and the connecting ring 2 are connected to each other.

[0023] The internal space of the annular groove 8 is annular, and the annular groove 8 can accommodate the movement of the abutment block 9 inside it.

[0024] The bottom end of the connecting rod 3 passes through the mounting base 1 and the dust cover 7 in sequence and extends into the interior of the annular groove 8, and the connecting rod 3 and the connecting ring 2 are connected to each other by threads.

[0025] The insert ring 5 has internal threads, and the screw 10 is connected to the insert ring 5 by threads.

[0026] The inner diameter of the rotating ring 11 is larger than the outer diameter of the rotating rail 12, and the rotating ring 11 can rotate on the outer wall of the rotating rail 12;

[0027] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when using this mechanism, rotating bolt 6 causes the rotating rail 12 and screw 10 to rotate, causing the screw 10 to unscrew from the inside of the insert ring 5. The screw 10 then causes the rotating rail 12 to rise, which in turn causes the rotating ring 11 to move. The rotating ring 11 then moves the mounting bracket 4, which in turn causes the mounting bracket 4 to move the connecting ring 2 upward. The connecting ring 2 then moves the connecting rod 3, which in turn moves the abutment block 9, causing the abutment block 9 to press tightly against the inner wall above the ring groove 8.

[0028] Working principle: The operator holds the dust cover 7 and inserts the abutment block 9 into the annular groove 8 through the socket 13. Then, the operator rotates the rotating ring 11, which drives the mounting bracket 4 to rotate. The mounting bracket 4 drives the connecting ring 2 to rotate, which in turn drives the connecting rod 3 and the abutment block 9, causing the abutment block 9 to shift from the socket 13. The operator can then rotate the bolt 6 with a tool, which drives the rotating rail 12 and the screw 10 to rotate. This causes the screw 10 to unscrew from inside the socket 5, and the screw 10 drives the rotating rail 12 to rise. The rotating rail 12 then drives the rotating ring 11, which in turn drives the mounting bracket 3 to rotate. Mounting bracket 4 causes the connecting ring 2 to move upward, which in turn drives the connecting rod 3, which in turn drives the abutment block 9, making the abutment block 9 fit tightly against the inner wall above the annular groove 8. When it rises to its maximum value, the dust cover 7 can be tightened. If it needs to be disassembled after long-term use, the bolt 6 can be turned in the opposite direction to make the abutment block 9 gradually move away from the inner wall above the annular groove 8. At this time, the fixation of the dust cover 7 will loosen. Then, turn the connecting ring 2 again to drive the connecting rod 3 and the abutment block 9, so that the abutment block 9 is located at the insertion port 13. By holding the dust cover 7, the dust cover 7 can be separated from the mounting base 1.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
