Detailed implementation

[0024] For better explanation of the present utility model for easy understanding, the present utility model will be described in detail below in conjunction with the drawings through specific implementation manners.

[0025] Please refer to Figures 1 to 5 As shown, a detachable front bicycle headlight of the present utility model includes a headlight body 1 and a disassembly and assembly mechanism, and the disassembly and assembly mechanism is connected to the headlight body 1;

[0026] The disassembly and assembly mechanism includes an upper connection component and a lower connection component. The upper part of the upper connection component is detachably connected to the headlight body 1, and the lower connection component is detachably connected to the lower part of the upper connection component;

[0027] The lower connection component includes an installation bin 4, a bundling and fixing component, a mounting plate 16, two clamping keys 15 and a sealing plate 14. The bundling and fixing component is arranged at the lower part of the installation bin 4. An accommodating groove 18 adapted to the mounting plate 16 is arranged at the upper part of the installation bin 4. The mounting plate 16 is placed inside the accommodating groove 18. Limiting grooves adapted to the clamping keys 15 are oppositely arranged on both sides of the mounting plate 16. One clamping key 15 is detachably connected to the inside of one limiting groove. A first opening 19 is arranged in the middle of the mounting plate 16. Buckles 20 are arranged around the sealing plate 14. A clamping groove 17 adapted to the buckle 20 is arranged on the installation bin 4. The sealing plate 14 is pressed above the clamping key 15. One buckle 20 is clamped with one clamping groove 17. A second opening 13 is arranged in the middle of the sealing plate 14. The sides of the clamping key 15 close to the first opening 19 are all arranged as pressing parts. Protrusions 26 are arranged on both sides of the upper connection component. The upper connection component passes through between the first opening 19 and the second opening 13 and is detachably connected to the pressing parts through the protrusions 26.

[0028] The working principle of the present utility model is as follows: Before riding at night, the front lamp body can be tied to the front end of the bicycle through the bundling and fixing component, so that the rider can illuminate the road ahead through the lamp body 1 when riding at night. When the lamp body needs to be disassembled for charging or maintenance, the rider can rotate the upper connection component through the lamp body 1, so that the two protrusions 26 on the upper connection component rotate in the first opening 19, so that the two protrusions 26 are disengaged from the pressing of the key 15. Subsequently, the upper connection component under the lamp body 1 is separated from between the first opening 19 and the second opening 13, so that the lamp body 1 is separated from the bicycle. When it is necessary to install the charged lamp body 1 onto the bicycle, the protrusion 26 on the upper connection component can be misaligned with the key 15 first, and then the upper connection component at the lower part of the lamp body 1 is placed inside the first opening 19, and then the upper connection component is rotated, so that the protrusion 26 on the upper connection component is pressed under the key 15 for fixation, so that the lamp body 1 is quickly installed on the bicycle.

[0029] Further, the bundling and fixing component includes a strap 3, a knob 5 and a rotating column 8. The strap 3 is connected to the lower part of the installation bin 4. A plurality of racks 2 are arranged in a row on one side of the strap 3. The rotating column 8 is arranged on the other side of the strap 3. The knob 5 is sleeved on the outer surface of the rotating column 8 and is rotatably connected to the rotating column 8. A first through hole 239 is arranged between the knob 5 and the rotating column 8. A second through hole 237 is arranged on the side of the strap 3 close to the first through hole 239. A spiral tooth groove 10 adapted to the rack 2 is arranged on the inner surface of the knob 5. One side of the strap 3 passes through the first through hole 239 and the second through hole 237, and one side of the strap 3 is detachably connected to the spiral tooth groove 10 through the rack 2.

[0030] As can be seen from the above description, when it is necessary to install the front lamp on the front crossbar of the bicycle, the installation bin 4 can be first pressed on the crossbar, and then one side of the strap 3 is wound around the lower part of the crossbar and passes through the first through hole 239 and the second through hole 237, so that the rack 2 on one side of the strap 3 meshes with the spiral tooth groove 10. Subsequently, the knob 5 is rotated, and while the knob 5 rotates, one side of the strap 3 is tightened through the rack 2, so that the strap 3 is bundled and fixed on the crossbar.

[0031] Further, the upper connection assembly includes a connecting member 12 and a screw. A plurality of pins 24 are provided on the upper part of the connecting member 12, and a jack 6 adapted to the pins 24 is provided on the lower part of the headlight body 1. One of the pins 24 is inserted into one of the jacks 6. The outer part of the connecting member 12 is detachably connected to the headlight body 1 through the screw. A column 25 is provided on the lower part of the connecting member 12. The diameter of the upper part of the column 25 is larger than the diameter of the lower part of the column 25, and the diameter of the lower part of the column 25 is smaller than the diameter of the first opening 19. The protrusions 26 are provided on both sides of the lower part of the column 25.

[0032] As can be seen from the above description, when it is necessary to disassemble the headlight body 1, the headlight body 1 can be rotated to drive the connecting member 12 to rotate, so that the protrusion 26 originally pressed under the key 15 is separated from under the key 15. Then, the headlight body 1 is lifted to make the column 25 separate from the outside of the first opening 19 and the second opening 13 under the drive of the headlight body 1, so that the upper connection assembly is separated from the lower connection assembly.

[0033] Further, it further includes a leveling tray 11. The leveling tray 11 is also provided between the headlight body 1 and the connecting member 12. The upper part of the leveling tray 11 is adapted to the lower part of the headlight body 1 and fits against the lower part of the headlight body 1. The upper part of the connecting member 12 is pressed against the lower part of the leveling tray 11.

[0034] As can be seen from the above description, it is beneficial to better adapt to the shape of the outside of various headlight bodies 1 through the leveling tray 11 to achieve a leveling effect, so that the connecting member 12 can be better pressed on the headlight body 1 flatly through the leveling tray 11, and the headlight body 1 can be better supported by the leveling tray 11.

[0035] Further, it further includes a positioning strip 22. An opening is oppositely provided on the upper part of the connecting member 12. The openings are alternately arranged with the protrusions 26. One of the positioning strips 22 is connected to the inside of one of the openings. A positioning block 27 is provided on the lower part of the positioning strip 22. A positioning groove 21 adapted to the positioning block 27 is provided on the upper part of the sealing plate 14. The positioning groove 21 is alternately arranged with the key 15. One of the positioning blocks 27 is movably connected to one of the positioning grooves 21.

[0036] As can be seen from the above description, when it is necessary to reinstall the headlight body 1 on the bicycle, the protrusion 26 of the connecting member 12 can be staggered from the key 15 first. Then, the column 25 at the lower part of the connecting member 12 can be placed inside the first opening 19 and the second opening 13. Subsequently, the connecting member 12 is rotated to drive the column 25 to rotate, so that the protrusion 26 is rotated under the key 15 for pressing. After the protrusion 26 is in place, the positioning block 27 on the positioning strip 22 is rotated into the positioning groove 21 for fixation, so that the connecting column on the connecting member 12 can no longer rotate randomly.
