Technical Field

[0001] The utility model relates to the technical field of bicycle fixing clamps, in particular to a bicycle fixing clamp. Background Art

[0002] In the prior art, in order to facilitate the fixation of bicycles during transportation, fixing clamps are usually provided to clamp the bicycles, thereby ensuring the limited fixation of a large number of bicycles and preventing the bicycles from being deflected or shaken during transportation.

[0003] The existing patent discloses a tightening device for clamping a bicycle by plugging a toothed belt and a clamping plate, wherein the teeth of the toothed belt and the clamping plate are inclined in opposite directions, thereby preventing the toothed belt from automatically loosening.

[0004] However, the fixing clamp structure of the toothed belt binding lacks a fastening device, and its fastening and clamping of the bicycle completely relies on the traction of the toothed belt. Therefore, during the clamping process, the toothed belt extends through the upper end of the pallet, and a large pulling force needs to be applied to the toothed belt to achieve the toothed belt binding and fixing of the bicycle. There is a lack of adjustment of the clamping preload, which can easily cause the belt to loosen during transportation. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figures 1 to 7 , the utility model provides a technical solution:

[0027] A bicycle fixing clamp comprises a fixing clamp 1, one end of the fixing clamp 1 is provided with a clamping toothed belt 5, the other end of the fixing clamp 1 is provided with a first clamping plate 4, a first slot 7 for accommodating the clamping toothed belt 5 to pass through and be inserted is provided between the first clamping plate 4 and the fixing clamp 1, a limiting block 14 is provided on the first clamping plate 4, a height-adjustable pressing frame 10 is provided in the inner cavity of the fixing clamp 1, the lower end of the pressing frame 10 is pressed on the upper end of the limiting block 14, a locking buckle 6 is provided on the fixing clamp 1, the other end of the locking buckle 6 extends into the inner cavity of the fixing clamp 1 and is rotatably connected to a cam 9, and the cam 9 is pressed on the pressing frame 10.

[0028] The pressing frame 10 is used to limit the upward rotation angle of the first clamping plate 4, and the lock buckle 6 and the cam 9 cooperate to lock the height of the pressing frame 10, thereby improving the protection of the clamping state.

[0029] The first clamping plate 4 is provided with a rack whose inclination direction is opposite to that of the teeth on the clamping toothed belt 5. The clamping toothed belt 5 is inserted into the first slot 7 to form an inner cavity with the fixing clamp 1, thereby clamping the bicycle. The volume of the inner cavity is reduced by pulling the clamping toothed belt 5, thereby achieving the purpose of fixed clamping.

[0030] The fixing clamp 1 is provided with a second clamping plate 8 located at the lower end of the first clamping plate 4, and the second clamping plate 8 is rotatably mounted on the fixing clamp 1 through an elastic torsion spring 17. A rotating shaft 11 is provided at the lower end of the fixing clamp 1, and the second clamping plate 8 is rotatably mounted on the rotating shaft 11 through an elastic torsion spring 17. The fixing clamp 1 is provided with a positioning block 18 located at the lower end of the first clamping plate 4, and the other end of the elastic torsion spring 17 is provided with a connecting frame 13 inserted into the positioning block 18.

[0031] The second clamping plate 8 is elastically rotatably mounted by the cooperation of the rotating shaft 11 and the elastic torsion spring 17 , and the rotation angle of the second clamping plate 8 is limited by the positioning block 18 and the connecting frame 13 .

[0032] One end of the second card plate 8 extends to the lower end of the first card plate 4, and the other end of the second card plate 8 extends to the rear side of the rack, and a plurality of groups of push teeth 12 are provided at the end of the second card plate 8, and the push teeth 12 have the same inclination direction as the rack, and the number of the push teeth 12 is set to at least two groups, and a second slot 16 is provided between the second card plate 8 and the first card plate 4.

[0033] The positioning block 18 is used to limit the lower end position of the first clamping plate 4 to avoid downward deflection. After the clamping toothed belt 5 is clamped, the second clamping plate 8 is rotated to make the push tooth 12 engage with the clamping toothed belt 5 extending to the outside of the first clamping plate 4, so that the rotation of the second clamping plate 8 drives the push tooth 12 to pull the clamping toothed belt 5 to further stretch to the other side of the first slot 7, thereby achieving the adjustment of the clamping force under the adjustment size of the tooth gap.

[0034] A pair of symmetrically distributed clamping clamps 2 are provided on one side of the fixing clamp 1 . The pair of clamping clamps 2 surround a clamping inner cavity. The inner diameter of the clamping inner cavity is adjusted by the clamping clamps 2 through a locking device 3 .

[0035] By arranging the cooperation between the clamping hoop 2 and the locking device 3, the positioning installation of the fixing clip 1 is achieved.

[0036] Working principle: First, the clamping clamp 2 and the locking device 3 are used to cooperate to realize the positioning and installation of the fixing clamp 1 on the transport frame or the frame, and then the clamping toothed belt 5 is inserted into the first slot 7 to realize that the clamping toothed belt 5 and the fixing clamp 1 form an inner cavity, thereby achieving the purpose of clamping the bicycle. The volume of the inner cavity is reduced by pulling the clamping toothed belt 5 to achieve the purpose of fixed clamping. At this time, the pressing frame 10 and the positioning block 18 limit the position of the first clamping plate 4, and the rack at the end of the first clamping plate 4 is kept in mesh with the teeth of the clamping toothed belt 5 to prevent the clamping toothed belt 5 from moving in the opposite direction.

[0037] When the clamping toothed belt 5 cannot be pulled by manpower, the second clamping plate 8 is rotated to make the push tooth 12 engage with the clamping toothed belt 5 extending to the outside of the first clamping plate 4, so that the rotation of the second clamping plate 8 drives the push tooth 12 to pull the clamping toothed belt 5 to further stretch to the other side of the first slot 7, thereby achieving the adjustment of the clamping force under the adjustment size of the tooth gap.

[0038] When disassembly is required, the lock buckle 6 is opened to allow the cam 9 to rotate eccentrically, thereby releasing the lock on the upper end of the pressing frame 10, and by squeezing one end of the first clamping plate 4 to rotate upward, the meshing state of the rack clamping the toothed belt 5 at its end is released, making it easier to reversely pull the toothed belt 5, thereby achieving the purpose of disassembling the bicycle.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
