[0030] This utility model improves the bicycle bell, and specifically relates to a bicycle bell installed at the end of a curved handlebar. Of course, it can also be installed at the end of a straight handlebar. The bicycle bell of this utility model is connected to the end of the curved handlebar and cooperates with the wrapping tape, realizing the connection between the bicycle bell and the end of the curved handlebar, and also improving the aesthetics of the wrapped tape.

[0031] For details, please refer to one embodiment of this utility model. Figure 1 and Figure 2As shown, a bicycle bell includes a bell base 1, which is a circular, disc-shaped seat; a bell shell 2, which is connected to the upper end of the bell base and is made of metal, forming a closed cylindrical shape; a firing arm 3, which is made of bent metal rod and is connected to the side wall of the bell base 1; a mounting seat is formed on the outer side wall of the bell base, and the firing arm is connected to the mounting seat; a bell hammer 4 is connected to the firing arm; and a connecting sleeve 5 is provided at the lower end of the bell base 1. The connecting sleeve 5 has at least one slot 50 along the axial direction. During assembly, a wrapping tape is pre-wound around the handlebar tube, and then the connecting sleeve is fitted onto the tail of the handlebar tube and pressed onto the wrapping tape. The wrapping tape is then passed through the slot and continues to wrap around the surface of the connecting sleeve.

[0032] This utility model designs a bicycle bell, which is installed at the end of the handlebar tube and cooperates with the winding tape on the handlebar tube. When the connecting sleeve is fitted onto the end of the handlebar tube, the already wound winding tape is pressed during the fitting process to fix the end of the winding tape and to connect the connecting sleeve to the handlebar tube. At the same time, the unwound winding tape passes through the groove of the connecting sleeve to the outside of the connecting sleeve. The winding tape can be wrapped around the surface of the connecting sleeve and continue to be wrapped around the handlebar tube. Here, the winding tape is wrapped around the surface of the connecting sleeve. The surface of the winding tape is provided with adhesive, and after the winding tape is wrapped around the handlebar tube, it is connected to the handlebar tube as a whole, which also improves the connection reliability between the bicycle bell and the handlebar tube.

[0033] Another embodiment of this utility model is described in [reference needed]. Figure 3 As shown, the lower end of the bell holder 1 is also provided with an inner support tube 6. The inner support tube 6 is coaxially arranged with the connecting sleeve. During assembly, the inner support tube is inserted into the handlebar tube. Through the inner support tube, the bell is connected inside the handlebar tube. During the bell's stress process, the connection reliability between the bell and the handlebar tube can be improved, and the connecting sleeve is less likely to break or fail.

[0034] Furthermore, the inner support tube 6 includes at least two tube segments 60 arranged in a circular pattern. In one embodiment of this utility model, a design of four tube segments is adopted, with gaps between adjacent tube segments, so that the tube segments have a certain amount of deformability. During the assembly process of the inner support tube and the handlebar tube, the deformability of the tube segments can be used to further improve the connection reliability between the bell and the handlebar tube.

[0035] See further Figure 5As shown, it also includes an expansion block 61, which is located inside the inner support tube and connected to the bell shell via a screw. The expansion block 61 moves toward the bell shell to open the inner support tube and abut against the inner wall of the handlebar tube. The expansion block is a cone with a trapezoidal cross-section and a nut is provided inside the expansion block. The nut is connected to the screw. During the rotation of the bell shell, the screw will cause the expansion block to move toward the bell shell. During the movement, the inner support tube will be opened, so that the outer wall of the tube is tightly attached to the inner wall of the handlebar tube. The bell and handlebar tube are fixed by the maximum static friction between the tube and the inner wall of the handlebar tube.

[0036] In another embodiment of this utility model, the structure of the tube segment is further improved; see [link to relevant documentation]. Figure 6 As shown, the outer wall of the tube 60 is provided with a barb 601, and the inner wall of the handlebar tube 7 is provided with a groove 70 that mates with the barb. This provides another connection method. By engaging the barb and the groove, the bell is locked in the axial direction of the handlebar tube, ensuring the reliability of the connection between the bell and the handlebar tube. The outer diameter of the barb is larger than the inner diameter of the handlebar tube. In the initial stage of the assembly of the tube and the handlebar tube, the tube is compressed. When the inner support tube is inserted into the designated position, the tube is reset by its own elasticity, so that the barb on the tube engages in the groove, thereby locking the inner support tube and the handlebar tube.

[0037] The structure of the bell holder is further explained here; see [link to relevant documentation]. Figure 4 As shown, the upper end of the bell seat 1 is provided with a support rod 10, and the lower end face of the bell seat is provided with a concave nut mounting hole 11. The support rod 10 is a hollow rod. The bell shell 2 is provided with a screw 20. One end of the screw is connected to the inner wall of the bell shell by welding, and the screw is coaxial with the bell shell. The screw passes through the support rod and is connected to the nut 110 in the nut mounting hole to fix the bell shell and the bell seat.

[0038] In summary, this utility model has the following beneficial effects:

[0039] 1. This utility model designs a bicycle bell installed at the end of the handlebar tube. It is fixed by connecting the connecting tube to the end of the handlebar tube and combining it with the wrapping tape on the handlebar tube. This realizes the combination of bell installation and fixation with the wrapping tape. The bell seals the end of the handlebar tube and also ensures the fixation of the end of the wrapping tape. Furthermore, the wrapping tape also improves the reliability of the connection between the bell and the handlebar tube.

[0040] 2. This utility model also improves the reliability of the bell's connection in the handlebar tube axial direction by connecting the inner support tube to the inner wall of the handlebar tube, making it less likely to fall out and preventing the bell from being lost.

[0041] Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
