[0026] Reference Figures 1 to 5 As shown, this utility model provides a technical solution: a seat post bracket for bicycles, including a seat 10, a fixing component 20 and a locking component 30; the fixing component 20 includes a bayonet seat 21 and a connecting seat 22, the bayonet seat 21 is detachably connected to the seat 10, and the connecting seat 22 is connected to the bayonet seat 21; the locking component 30 is connected to the fixing component 20.

[0027] In this embodiment, the male seat 10 serves as an accessory installation platform. The modular assembly of the seat post bracket is achieved through the linkage of the fixing component 20 and the locking component 30. The detachable connection between the bayonet seat 21 and the male seat 10 allows users to adjust the fixing points according to the seat post size, while the locking component 30 provides binding force to ensure a tight fit between the bracket and the seat post. The split design improves the versatility and flexibility of the seat post bracket, enabling it to adapt to various seat post sizes. The detachable connection between the male seat 10 and the fixing component 20 facilitates maintenance and accessory replacement. The addition of the locking component 30 enhances the overall structure's vibration resistance, effectively reducing the risk of loosening due to bumps and improving installation stability.

[0028] Reference Figures 2 to 4As shown, in some embodiments, the male seat 10 is provided with a plurality of connection holes 11, and the bayonet seat 21 is provided with a first through hole 211 corresponding to each connection hole 11. The fixing component 20 includes fasteners 23, the number of fasteners 23 is the same as the number of first through holes 211, and the fasteners 23 correspond one-to-one with the first through holes 211. One end of the fastener 23 passes through the first through hole 211 and is connected to the connection hole 11.

[0029] In this embodiment, multiple connecting holes 11 are aligned with the first through hole 211, allowing fasteners 23 to pass through and connect the male seat 10 and the bayonet seat 21 in a uniformly distributed manner. This multi-point connection method disperses stress and avoids single-point overload. Furthermore, the use of multiple fasteners 23 significantly enhances the connection strength between the male seat 10 and the bayonet seat 21, preventing relative displacement and rotation. The uniformly distributed connection points improve the overall rigidity of the structure and effectively suppress loosening under vibration conditions.

[0030] Reference Figures 2 to 4 As shown, in some embodiments, the connecting hole 11 is a mounting hole, a nut 12 is provided in the mounting hole, and the fastener 23 is a bolt, one end of which passes through the first through hole 211 and is connected to the nut 12.

[0031] In this embodiment, the bolt passes through the first through hole 211 and is tightened with the embedded nut 12, thereby achieving a secure connection between the male seat 10 and the bayonet seat 21. The connection method of the bolt and nut 12 is easy to install and disassemble, while providing a high-strength fastening effect. The nut 12 is embedded in the mounting hole, avoiding external protrusion and making the structure more compact and aesthetically pleasing.

[0032] Reference Figure 2 and 5 As shown, in some embodiments, the connecting seat 22 has a second recess 221 corresponding to each first through hole 211.

[0033] In this embodiment, the second recess 221 is used to accommodate the head portion of the fastener 23 or bolt. When the tail of the fastener 23 passes through the first through hole 211 of the bayonet seat 21 and is locked, the head of the fastener 23 will be embedded in the second recess 221. The design of the second recess 221 realizes the "hiding" or "sinking" of the head of the fastener 23, avoiding the fastener 23 from protruding from the surface of the connecting seat 22, thereby preventing scratches or indentations on the surface of the seat tube caused by the end of the fastener 23 directly pressing against the seat tube during the locking process.

[0034] Reference Figures 2 to 4As shown, in some embodiments, the male seat 10 is provided with a limiting space on the side near the bayonet seat 21, and the bayonet seat 21 is provided with a limiting protrusion 212 on the side near the male seat 10. The limiting protrusion 212 provides a first recess 2121 for each connecting hole 11. When the limiting protrusion 212 is inserted into the limiting space, the hole wall of the connecting hole 11 extends into the first recess 2121 one by one.

[0035] In this embodiment, the cooperation of the limiting space and the limiting protrusion 212 achieves the initial positioning and anti-rotation function of the male seat 10 and the bayonet seat 21. The design of the first recess 2121 allows the hole wall of the connecting hole 11 to be embedded, avoiding interference between the hole wall and the limiting protrusion 212, while increasing the contact area. The cooperation of the limiting space and the limiting protrusion 212 ensures the precise alignment of the male seat 10 and the bayonet seat 21, simplifying the assembly process.

[0036] Reference Figures 2 to 4 As shown, in some embodiments, a positioning protrusion 13 is provided in the limiting space, and a first concave portion 2122 is provided in the limiting protrusion 212 corresponding to the positioning protrusion 13. When the limiting protrusion 212 is inserted into the limiting space, the positioning protrusion 13 extends into the first concave portion 2122.

[0037] In this embodiment, the cooperation between the positioning protrusion 13 and the first recess 2122 provides an additional positioning point, ensuring that the limiting protrusion 212 can only be inserted into the limiting space in a specific direction, thus achieving directional assembly. This further improves the accuracy and efficiency of assembly and prevents incorrect installation.

[0038] Reference Figure 2 and Figure 5 As shown, in some embodiments, the connecting seat 22 has a second recess 222 on the side opposite to the bayonet seat 21.

[0039] In this embodiment, the second concave portion 222 is used to contact the surface of the bicycle seat tube. Its arc or concave surface can fit the surface of the seat tube, thereby increasing the contact area between the connecting seat 22 and the seat tube. This not only disperses the pressure applied by the locking assembly 30 and reduces local stress, but also helps to prevent damage to the surface of the seat tube and improves the stability of the fixation.

[0040] Reference Figure 2 As shown, in some embodiments, the radial cross-sectional diameter of the second recess 222 gradually increases along its own axial direction.

[0041] In this embodiment, the tapered profile allows the connector 22 to find a stable, non-parallel contact surface on the seatpost. This tapered surface compensates for the typical lean angle of the bicycle seatpost relative to the ground, allowing the male seat 10, ultimately fixed to the connector 22, to be adjusted to an ideal state that is substantially perpendicular to the ground. This ensures that the bicycle taillight mounted on the male seat 10 maintains the correct beam angle, thereby most effectively warning vehicles behind and greatly improving riding safety.

[0042] Reference Figure 2 As shown, in some embodiments, the surface of the second recess 222 is provided with a plurality of anti-slip protrusions 2221.

[0043] In this embodiment, the anti-slip protrusion 2221 increases the friction between the connecting seat 22 and the seat tube by increasing the surface roughness. The anti-slip protrusion 2221 effectively prevents the seat tube support from sliding or rotating on the seat tube, and can maintain a fixed position even on bumpy roads.

[0044] Optionally, the connector 22 may be made of silicone.

[0045] In this embodiment, the high elasticity and softness of silicone allow it to better conform to the surface of seat tubes of different diameters and shapes, adaptively filling tiny gaps to form a tighter fit. Furthermore, the soft silicone effectively absorbs and buffers high-frequency vibrations transmitted from the seat tube, reducing the impact of vibrations on the accessories on the male seat 10, and further reducing the risk of the locking assembly 30 loosening due to vibration.

[0046] Optionally, the bayonet mount 21 is made of rigid plastic.

[0047] For example, rigid plastics can be ABS plastic, nylon, or polycarbonate, etc.

[0048] In this embodiment, the bayonet seat 21 is made of rigid plastic, ensuring its strength and durability as the main structural component. It can reliably withstand the tensile force from the locking assembly 30 and the fastening force required to fix the male seat 10. Its good rigidity ensures the shape stability of precision structures such as the limiting protrusion 212 and the first recess 2121, thereby ensuring the accuracy and reliability of the connection with the male seat 10.

[0049] Reference Figures 1 to 2 and Figure 5 As shown, in some embodiments, the bayonet seat 21 has a second through hole 213, the locking assembly 30 includes a strap 31 and a hook 32, one end of the strap 31 is connected to the connecting seat 22, and the other end of the strap 31 passes through the second through hole 213. The strap 31 has multiple locking holes 311, and the hook 32 is installed on the bayonet seat 21. When the strap 31 is tied to the seat post of the bicycle, the hook 32 engages with one of the locking holes 311.

[0050] In this embodiment, the strap 31 passes through the second through hole 213 and wraps around the seat tube. The user tightens the free end of the strap 31 and selects a suitable locking hole 311 to engage with the hook 32. During this process, the tightened strap 31 causes the connecting seat 22 to press tightly against the seat tube, while the locking seat 21 covers and presses against the connecting seat 22. The two, through the tension of the strap 31 and the locking of the hook 32, form a compact overall structure that wraps around the seat tube. Multiple locking holes 311 provide stepless adjustment of the locking position, allowing the bracket to be firmly fixed on seat tubes of different diameters. The cooperation of the strap 31, hook 32, and fixing component 20 forms a compact overall structure with high rigidity, which can effectively resist bumps and vibrations and prevent displacement or loosening caused by vibration.

[0051] Reference Figure 4 As shown, in some embodiments, the hook 32 is configured in a T-shape.

[0052] In this embodiment, the T-shaped hook 32 has a large contact area and an easy-to-operate shape, allowing it to quickly engage and release with the locking holes 311 on the strap 31. This provides a more stable engagement effect, reduces the risk of the strap 31 slipping off, and enhances the reliability of the locking mechanism.

[0053] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
