Description
Technical Field
[0001] This application relates to the field of bicycle parts technology, and in particular to a quick-release structure for a bicycle saddle tube. Background Technology
[0002] As a traditional and practical means of transportation, the bicycle has undergone many years of development and is now widely used in various fields such as daily commuting, fitness activities, and competitive sports. It not only boasts environmentally friendly and energy-saving features but also brings convenience and enjoyment to riders. With the continuous improvement of people's demands for riding experience and bicycle performance, the design and improvement of various bicycle components have received increasing attention. Among them, the bicycle saddle tube, as a crucial component connecting the frame and saddle, directly affects riding comfort and safety due to its structure and performance. A well-designed saddle tube structure provides stable support for the rider while allowing for height adjustments to suit individual needs and different riding postures and road conditions.
[0003] In existing technologies, quick-release clamp structures are typically used to achieve rapid disassembly and installation of bicycle seatposts. These structures usually consist of a clamp body, a screw, and a rotating arm. By rotating the rotating arm, the screw causes the clamp body to tighten or loosen, thereby achieving the fixing and disassembly of the seatpost.
[0004] However, in actual use, the rotating arm of some parts may accidentally extend, for example, easily snagging on the rider's clothing or other items. This not only affects the convenience of riding, but may also lead to safety hazards. Utility Model Content
[0005] To improve riding convenience and safety, this utility model provides a quick-release structure for bicycle saddle tubes.
[0006] The quick-release structure for a bicycle saddle tube provided by this utility model adopts the following technical solution:
[0007] A quick-release structure for a bicycle saddle post includes a ring body, a fixing bolt, a rotating arm, and a protective assembly. The ring body has a first fixed end and a second fixed end. The fixing bolt passes through the first fixed end and the second fixed end. The rotating arm is connected to one end of the fixing bolt, and the other end of the fixing bolt is connected to the protective assembly. The protective assembly includes a mounting block and an anti-snag bar. The mounting block is connected to the ring body, and the fixing bolt is threadedly connected to the mounting block. One end of the anti-snag bar is rotatably connected to the mounting block. The rotating arm has a handle for operating the rotating arm. The end of the anti-snag bar away from the mounting block has a protective part that hooks with the handle and is located on the side of the handle away from the ring body.
[0008] By adopting the above technical solution, the ring is fitted onto the bicycle saddle tube, and the fixing bolts can be operated by rotating the arm; the protective part of the anti-snag bar can hook onto the handlebar, and the anti-snag bar is located on the side of the handlebar away from the ring. The protective part can play a protective role, reducing the possibility of other objects getting caught on the handlebar, avoiding misoperation, and at the same time facilitating the operation of the rotating arm to achieve quick release of the bicycle saddle tube.
[0009] Preferably, the anti-snag rod is connected to a locking assembly, which includes a limiting block, an insert rod, and a fixing rod. The handle portion has a fixing hole and a fixing cavity. The fixing hole communicates with the fixing cavity and the outside. The limiting block is slidably connected to the anti-snag rod. The insert rod is fixedly connected to the anti-snag rod. The fixing rod is connected to the end of the insert rod away from the limiting block. The insert rod can be selectively inserted into the fixing hole. When the insert rod passes through the fixing hole and extends into the fixing cavity, the fixing rod can be selectively engaged with the handle portion.
[0010] By adopting the above technical solution, the locking component can slide the limiting block on the anti-snag bar, so that the insertion rod is aligned with the fixing hole of the handle and inserted. When the insertion rod passes through the fixing hole and extends into the fixing cavity that communicates with the fixing hole, the limiting block is rotated to make the fixing rod engage with the handle, thus realizing a reliable connection between the anti-snag bar and the handle, preventing the anti-snag bar from shaking or accidentally disengaging during riding, and ensuring the stability and safety of the quick-release structure.
[0011] Preferably, it also includes a switch assembly for adjusting whether the fixing rod is engaged with the handle portion.
[0012] By adopting the above technical solution, the switch assembly can adjust the engagement state between the fixed rod and the handle, thereby achieving flexible control over the connection between the anti-snagging rod and the handle.
[0013] Preferably, the switch assembly includes a connecting rod, a handheld head, a rotating shaft, and a switch block. One end of the connecting rod is connected to the handheld head, and the other end is connected to the rotating shaft. The switch block is connected to the rotating shaft. A switch slot is provided on the limiting block. When the switch block is inserted into the switch slot, it drives the locking assembly to rotate.
[0014] By adopting the above technical solution, when in use, the switch block is inserted into the switch slot of the limit block, and the connecting rod, rotating shaft and switch block are rotated by holding the hand head, which in turn drives the locking component to rotate, thereby realizing the effective adjustment of the rotation state of the locking component.
[0015] Preferably, it further includes a reinforcing component. The limiting block has a movable cavity, and the reinforcing component is disposed in the movable cavity. The reinforcing component includes a reinforcing rod, a slider, a control block, and a control rod. The anti-snagging rod has a limiting hole, the reinforcing rod passes through the anti-snagging rod, and can be selectively inserted into the limiting hole. The slider is connected to the other end of the reinforcing rod. The control block has a sliding groove, which is inclined along its length. The slider is disposed in the sliding groove and slidably connected to the control block. The control block is slidably connected to the limiting block. The control rod is connected to the control block. The movable cavity communicates with the switch slot. The switch block extends through the switch slot into the movable cavity. When the switch block overlaps with the controlled rod, it is used to drive the control block to move, so that the reinforcing rod moves away from the limiting hole.
[0016] By adopting the above technical solution, when the switch block extends through the switch slot into the movable cavity and overlaps with the control rod, it can drive the control block to slide within the limiting block. Because the sliding groove on the control block is inclined along its length, the sliding of the control block will drive the reinforcing rod to move via the slider, causing the reinforcing rod, which was originally inserted into the limiting hole, to disengage from the limiting hole and retract into the limiting rod. When the reinforcing rod extends into the limiting hole, it can limit the locking assembly, enhancing the stability and reliability of the bicycle saddle tube quick-release structure.
[0017] Preferably, the reinforcing component further includes a connecting block and a spring. The connecting block is connected to the control block, one end of the spring is connected to the connecting block and the other end is connected to the limiting block. When the spring is in a stretched state, the reinforcing rod disengages from the limiting hole.
[0018] By adopting the above technical solution, when the spring is in its normal state, the reinforcing rod is inserted into the limiting hole. When the switch block is inserted into the movable cavity and overlaps with the control rod, the positions of the control block and connecting block are adjusted by adjusting the position of the control rod, causing the reinforcing rod to retract into the limiting block and simultaneously stretching the spring. When the switch block no longer exerts force on the control rod, the spring resets the connecting block, control block, and control rod. The position of the reinforcing rod can be flexibly adjusted, facilitating the operation and adjustment of the quick-release structure and improving its ease of use and flexibility.
[0019] Preferably, a gasket is provided between the rotating arm and the ring body, and the gasket is fixedly connected to the ring body and abuts against the rotating arm.
[0020] By adopting the above technical solution, the direct friction between the rotating arm and the ring body can be reduced, the service life of the rotating arm and the ring body can be extended, and the fixedly connected gasket can stably play a buffering and protective role.
[0021] In summary, this utility model has the following beneficial effects:
[0022] The ring is fitted onto the bicycle saddle tube, and the fixing bolts can be operated by rotating the arm. The protective part of the anti-snag bar can hook onto the handlebar, and the anti-snag bar is located on the side of the handlebar away from the ring. The protective part can play a protective role, reducing the possibility of other objects snagging on the handlebar and avoiding accidental operation. At the same time, it is easy to operate the rotating arm to quickly remove the bicycle saddle tube. Attached Figure Description

[0033] A quick-release structure for a bicycle saddle tube, as shown in the reference. Figure 1 and Figure 2 The bicycle saddle tube assembly includes a ring body 1, a fixing bolt 2, a rotating arm 3, and a protective component 5. The ring body 1 has a first fixing end 11 and a second fixing end 12, through which the fixing bolt 2 passes. One end of the fixing bolt 2 is fixedly connected to the rotating arm 3, and the other end is connected to the protective component 5. This structural design allows the ring body 1 to be tightened and loosened by operating the rotating arm 3, thus enabling quick-release of the bicycle saddle tube. The protective component 5 includes a mounting block 51 and an anti-snag bar 52. The mounting block 51 is fixedly connected to the ring body 1 and threadedly connected to the fixing bolt 2. The first end of the anti-snag bar 52 is rotatably connected to the mounting block 51. The rotating arm 3 has a handle 31, and the anti-snag bar 52 has a protective part 521. The protective part 521 hooks with the handle 31 and is located on the side of the handle 31 away from the ring body 1, reducing the possibility of the rotating arm 3 accidentally unfolding and improving riding safety and convenience.
[0034] Reference Figure 2 A gasket 4 is provided between the rotating arm 3 and the ring body 1. The gasket 4 is fixedly connected to the ring body 1 and abuts against the rotating arm 3, which can reduce the direct friction between the rotating arm 3 and the ring body 1, extend the service life of the rotating arm 3 and the ring body 1, and the gasket 4 can stably play a buffering and protective role.
[0035] Reference Figure 2 and Figure 3The anti-snagging rod 52 is connected to a locking assembly 6, which includes a limiting block 61, an insert rod 62, and a fixing rod 63. The anti-snagging rod 52 has a placement cavity 522 and a first insertion hole 523, which communicates with the placement cavity 522. The limiting block 61 is cylindrical and is located within the placement cavity 522, slidingly connected to the anti-snagging rod 52. Both the insert rod 62 and the fixing rod 63 are located within the first insertion hole 523. One end of the insert rod 62 extends into the placement cavity 522 and is fixed to the limiting block 61, while the fixing rod 63 is fixedly connected to the insert rod 62.
[0036] Reference Figure 2 and Figure 3 The handle portion 31 has a fixing hole 32 and a fixing cavity 33. The fixing hole 32 connects the fixing cavity 33 to the outside. The insertion rod 62 can be selectively inserted into the fixing hole 32. When the fixing assembly passes through the fixing hole 32 and extends into the fixing cavity 33, the fixing rod 63 can be selectively engaged with the handle portion 31.
[0037] The locking component 6 connected to the anti-snag bar 52 can be inserted into the fixing hole 32 through the insertion rod 62 and the fixing rod 63 can be engaged with the handle 31 to achieve a reliable connection between the anti-snag bar 52 and the handle 31, which enhances the stability and firmness of the quick-release structure and reduces the possibility of the anti-snag bar 52 accidentally detaching from the handle 31 during riding.
[0038] Reference Figure 2 and Figure 3 The anti-snagging rod 52 has a second insertion hole 524, the second insertion rod 62 is connected to the placement cavity 522, and the second insertion hole 524 and the first insertion hole 523 are respectively located on both sides of the placement cavity 522.
[0039] Reference Figure 2 and Figure 3 The limiting block 61 is connected to a switch assembly 7, which is used to adjust whether the fixing rod 63 is engaged with the handle part 31. The switch assembly 7 includes a connecting rod 71, a hand-held head 72, a rotating shaft 73, and a switch block 74. One end of the connecting rod 71 is fixedly connected to the hand-held head 72, and the other end is fixedly connected to the rotating shaft 73. The switch block 74 is fixedly connected to the rotating shaft 73. The limiting block 61 has a switch groove 611. When the connecting rod 71 is inserted into the second insertion hole 524 and the switch block 74 is inserted into the switch groove 611, it drives the locking assembly 6 to rotate.
[0040] The switch assembly 7 makes adjusting the engagement state of the fixing rod 63 and the handlebar 31 more convenient and quick. By operating the switch block 74, the locking assembly 6 is rotated, thereby enabling the insertion and removal of the insertion rod 62, and thus controlling the engagement and disengagement of the fixing rod 63 and the handlebar 31. This design improves the convenience and accuracy of operation, and further optimizes the performance of the bicycle saddle tube quick-release structure.
[0041] Reference Figure 4 and Figure 5 It also includes a reinforcing component 8. A movable cavity 612 is formed within the limiting block 61, and the reinforcing component 8 is disposed within the movable cavity 612. The reinforcing component 8 includes a reinforcing rod 81, a slider 82, a control block 83, a control rod 84, a connecting block 85, and a spring 86. A limiting hole 525 is formed on the anti-snagging rod 52. One end of the reinforcing rod 81 is fixedly connected to the slider 82, and the other end passes through the limiting block 61 and can be selectively inserted into the limiting hole 525. The control block 83 is slidably connected to the limiting block 61, and the control rod 84 is fixedly connected to the control block 83. A groove 831 is formed on the control block 83. The groove 831 is inclined along its length and slopes away from the limiting hole 525 from one end to the other. The slider 82 is disposed within the groove 831 and slidably connected to the control block 83.
[0042] Reference Figure 3 , Figure 4 and Figure 5 The movable cavity 612 is connected to the switch slot 611. The switch block 74 extends through the switch slot 611 into the movable cavity 612. When the switch block 74 overlaps with the control rod 84, it is used to drive the control block 83 to move, so that the reinforcing rod 81 is away from the limiting hole 525.
[0043] Reference Figure 4 and Figure 5 The connecting block 85 is fixedly connected to the control block 83, and one end of the spring 86 is fixedly connected to the connecting block 85 and the other end is fixedly connected to the limiting block 61. When the spring 86 is in the normal state, the reinforcing rod 81 extends out of the limiting block 61; when the spring 86 is in the stretched state, the reinforcing rod 81 disengages from the limiting hole 525 and retracts into the limiting block 61.
[0044] The reinforcement component 8 further enhances the connection strength between the anti-snag bar 52 and the handlebar 31. When the switch block 74 moves the control block 83, the reinforcement bar 81 is inserted into or pulled out of the limiting hole 525 through the cooperation of the slider 82 and the slide groove 831, thus achieving the reinforcement function. The spring 86 not only allows the reinforcement bar 81 to retract when reinforcement is not needed, but also allows the reinforcement bar 81 to automatically insert into the limiting hole, improving the flexibility and reliability of use, and further enhancing the overall performance of the bicycle saddle tube quick-release structure.
[0045] The operating principle of this application is as follows: The ring 1 is fitted onto the bicycle saddle post. The tightening and loosening of the ring 1 can be controlled by rotating the arm 3 and operating the fixing bolt 2, thus achieving the quick-release function of the bicycle saddle post. Then, the anti-snag bar 52 is rotated so that its protective part 521 passes over the handlebar part 31, hooking the protective part 521 onto the handlebar part 31. At this time, the protective part 521 is located on the side of the handlebar part 31 away from the ring 1, which can protect the rotating arm 3, reduce the possibility of other objects snagging on the handlebar part 31, avoid accidental operation, and facilitate the operation of the rotating arm 3 to achieve quick release of the bicycle saddle post.
[0046] In addition, the design of the locking assembly 6, the switch assembly 7, and the reinforcement assembly 8 further enhances the stability of the connection between the anti-hanging rod 52 and the rotating arm 3, while also achieving an anti-theft effect.
[0047] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
