[0036] The following combines the attached Figures 1-6The following further describes the present application with specific embodiments:
[0037] First of all, it should be noted here that in the description of the present application, when orientation terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the drawings. It is only for the convenience of description and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, so it cannot be understood as a limitation to the present application; in addition, when digital quantifiers such as "first", "second", "third", etc. appear, they are only for descriptive purposes and cannot be understood as indicating or implying relative importance. In addition, in the present application, unless otherwise clearly specified and limited, when terms such as "installation", "connection", and "coupling" appear, they should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, an interference fit, a transition fit, etc., or an integral connection; it can be directly connected or indirectly connected through an intermediate medium; therefore, for those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.
[0038] As Figures 1 through 6 shown, a bicycle lamp bracket includes: a main body 2, a rope 3, and a locking assembly 4. The main body 2 has a hook portion 23. The rope 3 can be sleeved on the hook portion 23. The locking assembly 4 is fixed on the main body 2. The locking assembly 4 is connected to both ends of the rope 3 and is used to tighten or loosen the rope 3.
[0039] In the present application, the main body 2 is arranged on the handle 100. Then, the rope 3 is sleeved on the hook portion 23 so that the rope 3 surrounds the bicycle handle 100. At this time, the rope 3 is in a relatively loose state. By operating the locking assembly 4, the rope 3 can be tightened. As the rope 3 is tightened, the entire bicycle lamp bracket can be firmly fixed on the handle 100, providing a stable support foundation for the subsequent installation of the bicycle lamp; when it is necessary to adjust the position of the bicycle lamp bracket or remove it from the bicycle handle 100, the locking assembly 4 can be operated again to make it in a state of loosening the rope 3. At this time, the tension on both ends of the rope 3 is reduced, and the rope 3 becomes loose, so that the bracket can be conveniently removed from the handle 100 or its position can be readjusted.
[0040] Compared with the traditional bicycle lamp bracket using a belt buckle, this design overcomes the situation that the belt has fatigue damage or even breaks after being used for a long time. The rope 3 usually has better flexibility and durability and is not likely to suddenly break due to long-term stress under normal use conditions, thereby improving the service life and reliability of the bicycle lamp bracket.
[0041] Specifically, as shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 the locking assembly 4 includes: a ratchet wheel 41, a pawl structure 42, and an end cap 43. The ratchet wheel 41 is fixedly installed on the main body 2. The ratchet wheel 41 is cylindrical and has a ring tooth portion 411 on its inner circle. The pawl structure 42 includes a rotating portion 421 and two symmetrically arranged first limiting claws 422 and second limiting claws 423 on the rotating portion 421. Both the first limiting claw 422 and the second limiting claw 423 can be inserted into the tooth spaces 412 of the ring tooth portion 411. Among them, the first limiting claw 422 and the second limiting claw 423 respectively limit the clockwise rotation and counterclockwise rotation of the pawl structure 42. Both ends of the rope 3 are fixedly connected to the rotating portion 421. Among them, the pawl structure 42 can drive the rope 3 to tighten or loosen. The end cap 43 is rotatably connected to the ratchet wheel 41, and the end cap 43 has two symmetrically arranged first limiting protrusions 431 and second limiting protrusions 432. The first limiting protrusion 431 and the second limiting protrusion 432 respectively correspond to the first limiting claw 422 and the second limiting claw 423. The first limiting protrusion 431 and the second limiting protrusion 432 are used to abut against the corresponding first limiting claw 422 and second limiting claw 423 to make the corresponding first limiting claw 422 and second limiting claw 423 disengage from the tooth spaces 412. A limiting structure 435 is provided in the middle of the end cap 43, and a limiting groove 4211 is provided in the middle of the rotating portion 421. The limiting groove 4211 has a first limiting wall 42111 and a second limiting wall 42112. When the end cap 43 rotates clockwise, the first limiting protrusion 431 can abut against the corresponding first limiting claw 422 to make the first limiting claw 422 disengage from the tooth spaces 412, and the limiting structure 435 abuts against the first limiting wall 42111. When the end cap 43 rotates counterclockwise, the second limiting protrusion 432 can abut against the corresponding second limiting claw 423 to make the second limiting claw 423 disengage from the tooth spaces 412, and the limiting structure 435 abuts against the second limiting wall 42112.
[0042] In the initial state, the first limiting pawl 422 and the second limiting pawl 423 of the pawl structure 42 are respectively in positions where they can be engaged with the tooth gaps 412 of the inner ring tooth part 411 of the ratchet wheel 41, thereby restricting the clockwise and counterclockwise rotation of the pawl structure 42. Manually rotate the end cap 43 clockwise. As the end cap 43 rotates, the first limiting protrusion 431 on the end cap 43 will gradually approach and abut against the corresponding first limiting pawl 422. When the first limiting protrusion 431 abuts against the first limiting pawl 422, an external force will be applied to make the first limiting pawl 422 disengage from the tooth gap 412 of the inner ring tooth part 411 of the ratchet wheel 41, releasing the restriction on the clockwise rotation of the pawl structure 42. When the second limiting protrusion 432 abuts against the second limiting pawl 423, the second limiting pawl 423 will be made to disengage from the tooth gap 412 of the inner ring tooth part 411 of the ratchet wheel 41, releasing the restriction on the counterclockwise rotation of the pawl structure 42. After stopping the rotation of the end cap 43, the first limiting pawl 422 and the second limiting pawl 423 will re-engage with the tooth gap 412 and lock it.
[0043] When tightening is required, it can be rotated in any direction. When loosening is required, just rotate it in the direction opposite to the rotation direction during tightening.
[0044] The locking assembly 4 is relatively simple to operate in practice. The user can adjust the tightness state of the rope 3 just by performing a simple action of rotating the end cap 43 clockwise or counterclockwise.
[0045] Through the cooperation of the ratchet wheel 41 and the pawl structure 42, precise control of the tightening and loosening of the rope 3 can be achieved. Each time the end cap 43 is rotated to make the pawl structure 42 disengage from the restriction and rotate a certain angle, the rope 3 will be tightened or loosened accordingly to a certain extent. This precise control allows the user to adjust the rope 3 to the most suitable tightness state according to the specific situation of the bicycle handle 100 and the user's personal requirement for the fixing tightness of the bracket, ensuring that the bicycle lamp bracket can be firmly fixed without damaging the handle 100 due to excessive tightness or affecting the installation convenience.
[0046] Specifically, as Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 shown, a rotating column body 433 is provided in the middle of the end cap 43. The limiting structure 435 is connected to the rotating column body 433. The rotating column body 433 includes two spaced limiting half-columns 4331. A rotating hole 4212 is provided in the middle of the rotating part 421. A ring-shaped protrusion 42121 is provided on the inner wall of the rotating hole 4212. The rotating main body 2 is arranged in the rotating hole 4212, and the limiting half-columns 4331 cooperate with the ring-shaped protrusion 42121 to restrict the end cap 43 from coming off.
[0047] By arranging a rotating cylinder 433 in the middle of the end cap 43 and connecting it to the limiting structure 435, and at the same time arranging an annular protrusion 42121 on the inner wall of the rotating hole 4212 of the rotating part 421, and making the limiting half column 4331 of the rotating main body 2 cooperate with the annular protrusion 42121, an effective limiting mechanism is formed. This design can effectively prevent the end cap 43 from disengaging from the rotating part 421, ensuring that during use, whether the end cap 43 is frequently rotated when adjusting the tightness of the rope 3 or when encountering bumps, vibrations, etc. during cycling, the end cap 43 can always remain in the correct position and closely cooperate with the rotating part 421.
[0048] Specifically, as Figure 3 , Figure 4 , Figure 6 shown, the rotating part 421, the first limiting claw 422, and the second limiting claw 423 are integrally formed, and the first limiting claw 422 and the second limiting claw 423 have elasticity.
[0049] Specifically, as Figures 1-6 shown, the main body 2 includes a first connecting part 21 and a second connecting part 22, the first connecting part 21 and the second connecting part 22 are pivotally connected, an annular wall 211 is arranged on the first connecting part 21, and a receiving cavity is provided in the middle of the annular wall 211. The ratchet 41 is partially installed in the receiving cavity.
[0050] The first connecting part 21 and the second connecting part 22 are pivotally connected, enabling the main body 2 to have a certain ability to adjust the angle. When installing the bicycle lamp bracket, the included angle between the first connecting part 21 and the second connecting part 22 can be flexibly adjusted according to the specific shape, angle of the bicycle handle 100 and the personal need for the illumination angle of the bicycle lamp.
[0051] The annular wall 211 arranged on the first connecting part 21 and the receiving cavity in the middle thereof provide a special installation space for the ratchet 41 part. This design enables the ratchet 41 to be reasonably accommodated inside the main body 2.
[0052] Specifically, as Figure 6 shown, two first through holes 2111 are opened on the annular wall 211, and second through holes 413 corresponding and communicating with the two first through holes 2111 are opened on the ratchet 41. The two ends of the rope 3 pass through the first through holes 2111 and the second through holes 413.
[0053] Specifically, a limiting ring 414 is arranged on the outer ring of the ratchet 41, and a buckle 434 for fastening the limiting ring 414 is arranged on the end cap 43.
[0054] By means of the snap 434 fastening the limiting ring 414, an effective limiting constraint is formed in the axial direction between the end cover 43 and the ratchet 41. When the end cover 43 rotates, whether it is to adjust the tightness of the rope 3 during normal operation or is affected by external forces such as bumps and vibrations during riding, the snap 434 can firmly fasten the limiting ring 414 to prevent the end cover 43 from accidentally shifting or disengaging in the axial direction.
[0055] It should be noted that the above embodiments are only used to illustrate the present application and do not limit the technical solutions described in the present application. Although the present specification has described the present application in detail with reference to the above embodiments, those of ordinary skill in the art should understand that those skilled in the art can still modify the present application or make equivalent replacements, and all technical solutions and their improvements that do not depart from the spirit and scope of the present application should be covered within the scope of the claims of the present application.
