Detailed Implementation

[0020] 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.

[0021] Please see Figures 1 to 2 This embodiment of a novel bicycle hub includes a hub body 1, which includes two hub discs 12, a pivot 11, and a hub tube 13. Two abutment plates 22 are fixed to the outer surface of the hub tube 13. Sealing shells 21 are fitted to the left and right ends of the hub tube 13. Rubber rings 23 are fixed to the opposite side of the abutment plates 22 and the sealing shells 21 to enhance the sealing at the connection between the abutment plates 22 and the sealing shells 21. Connecting blocks 3 are fixed to the front and rear ends of the two sealing shells 21. The two sets of connecting blocks 3 are equipped with disassembly and assembly components inside.

[0022] Furthermore, two hub discs 12 are fixed to the outer surface of the hub cylinder 13. Connecting holes are provided at both ends of the hub cylinder 13, and bearings are fixed inside the connecting holes. The rotating shaft 11 is rotatably connected to the inside of the two bearings.

[0023] Meanwhile, each of the two sealing shells 21 has a through hole on one of its opposite walls, and the sealing shell 21 is a hollow circular shape. The opposite walls of the two sealing shells 21 are missing so that they can be fitted onto the surface of the hub tube 13. The abutment plate 22 is annular so that the hub tube 13 can pass through its interior. The inner side of the through hole and the inner side of the abutment plate 22 are both fixed with sealing rings so that the hub tube 13 can be located inside the sealing ring of the abutment plate 22 and fixed thereto. This allows the abutment plate 22 to be fixed to the surface of the hub tube 13, and the sealing rings can enhance the sealing of the connection. The rotating shaft 11 passes through the sealing ring of the through hole and can also pass through the interior of the sealing shell 21 so that the rotating shaft 11 can be connected to external components. This also enhances the sealing of the connection between the rotating shaft 11 and the sealing shell 21 and reduces the phenomenon of external dust and other particles moving into the sealing shell 21 through the through hole.

[0024] Please see Figures 2 to 3The disassembly and assembly assembly in this embodiment includes two insert rods 31 fixed to the opposite side of the two abutment plates 22. Positioning blocks 32 are inserted into the opposite side of the front and rear sets of insert rods 31. Pull ropes 33 are fixed to the opposite side of the front and rear sets of positioning blocks 32. Guide rollers 34 are abutted inside the pull ropes 33. The upper and lower ends of the guide rollers 34 are rotatably connected to the upper and lower walls of the inner cavity of the connecting block 3 through bearings. The other end of the pull ropes 33 is fixed to a moving plate 35. Screws 36 are rotatably connected to the opposite side of the left and right sets of moving plates 35 through bearings. The disassembly and assembly assembly also includes a thrust structure set at the opposite side of the front and rear sets of positioning blocks 32.

[0025] The two sealing shells 21 each have an insertion hole on one side facing each other for the two insertion rods 31 to be located inside them. The insertion rods 31 are inserted into the insertion hole so that they can be located inside the sealing shell 21. The two sets of insertion rods 31 each have a positioning hole on one side facing away from each other for the positioning block 32 to be located inside them. The positioning block 32 moves into the positioning hole so that the insertion rods 31 can be fixed in the insertion hole.

[0026] In addition, each of the two sets of connecting blocks 3 has a through hole on one side for the positioning block 32 to pass through its interior, and each of the two sealing shells 21 has a connecting hole on both the front and rear sides for the positioning block 32 to pass through its interior. The connecting hole is connected to the insertion hole so that the positioning block 32 can be moved out of the connecting block 3 through the through hole and moved into the insertion hole through the connecting hole.

[0027] In addition, the opposing sides of the left and right connecting blocks 3 are provided with threaded holes for the screw 36 to pass through. The screw 36 is threaded to the inside of the threaded hole, so that the screw 36 can move in or out of the interior.

[0028] Please see Figure 3 In this embodiment, the thrust structure includes a concave block 37 fixed to the left and right walls of the two sets of positioning blocks 32. Two crossbars 38 are slidably connected inside the concave block 37, and a resistance spring 39 is sleeved on the outer surface of the crossbars 38.

[0029] Secondly, the front and rear walls of the crossbar 38 are fixed to the front and rear walls of the inner cavity of the connecting block 3, and the pull rope 33 is positioned between the upper and lower sets of crossbars 38 on the same side to prevent the crossbar 38 from affecting the pull rope 33 in pulling the positioning block 32 to move.

[0030] Furthermore, each of the two sets of concave blocks 37 has two round holes on one side facing each other, allowing the crossbar 38 to pass through its interior, so that the concave blocks 37 can slide on the outer surface of the crossbar 38.

[0031] The working principle of the above embodiments is as follows:

[0032] In use, rotating the left and right sets of screws 36 causes them to move out of the connecting block 3 in opposite directions. This causes the left and right sets of sliding plates 35 to move in opposite directions, which in turn causes the front and rear sets of positioning blocks 32 to move in opposite directions via the pull rope 33. This causes the front and rear sets of positioning blocks 32 to move out of the insertion hole of the insertion rod 31 and into the connecting block 3. As the two sets of positioning blocks 32 move in opposite directions, they also cause the front and rear sets of concave blocks 37 to move in opposite directions. This allows the concave blocks 37 to press against the resistance spring 39, thus allowing the sealing shell 21 to be removed from the hub cylinder 13.

[0033] During installation, repeat the above steps to insert the rod 31 into the insertion hole of the sealing shell 21. The left and right sets of screws 36 drive the two sets of moving plates 35 to move relative to each other, so that the moving plates 35 no longer pull the pull rope 33. Then, the front and rear sets of resistance springs 39 push the front and rear sets of positioning blocks 32 to move relative to each other through the concave block 37, so that the positioning blocks 32 are inserted into the positioning holes of the rod 31.
