New description: [New technical field] The present invention provides a structural improvement of a bicycle hub ratchet cylinder, which is related to the wheel hub. [Prior Art] - The flower hub is mainly composed of - a ratchet test, a ratchet cylinder, a mandrel, and a plurality of bearings. The (4) is worn in purely corrective, and the miscellaneous wheel is placed on the complex ratchet. The ratchet teeth of the hub shell are matched with the one-way, and the bearing sleeve is disposed between the core and the components to assist the smooth rotation of the components; and the conventional ratchets of the ratchet cylinder have a strong rigidity. The c-shaped ring buckles the bundles of the various ratchets, and the various ratchets of the ship are limited, and when the various ratchets are used for resetting, the ratcheting of the chaff of the chaff is shaped and the movement is reversed. The ratchet of the clamshell presses the ratchet of the ratchet cylinder, so that the ratchet cylinder is idling without being driven, and when the ratchet limb is only set with three blocks, each Wei is too large, so in each per spine When the block is actuated, it does not cause the C to interlock and affect each other; however, in order to increase the efficiency of the ratcheting, some people set the ratchet barrel with six ratchets to shorten the distance between the ratchets. Because the distance between the ratchets is shortened, ## will generate a G-shaped buckle with a bunch of shadows when the ratchets move. The adjacent ratchets are caused to have unintended actions; therefore, there is another conventional technique in which a rigid C-shaped loop is changed into a loop-shaped elastic member to loop the spines, by texture The softer components overcome the Ud problem, but the elastic component is specially made to fit the spines. It is a special 3 M425782 product, which is difficult to manufacture, and the material cost is high. In addition, when the spine continues The grounding action causes the elastic member to be continuously stretched and reset, so that the elastic member is very likely to be elastically fatigued, and affects the smoothness of the card (four) joint action. In view of this, the creator conceived and further studied and finally created a structural improvement of a bicycle hub ratchet. [New content] This creation provides a structural improvement of the bicycle hub ratchet cylinder, and its main purpose is to ensure that the ratchets that are hybrid with the hub shell can be kept in a normal state, and the salivation action is ensured. In order to achieve the above purpose, the present invention provides a structural improvement of a bicycle flower valley ratchet cylinder having a plurality of Kona ratchets on the ratchet cylinder, and the ratchet block may have a ratcheting one-way sounding of the shell and the age of the ratchet is Outward ship, reverse _ press down the thorns and idling 'This is created on the outer periphery of each ratchet to the metal c-clip, the c-shaped buckle to limit the position of each ratchet, and limit the spine to a limited extent The stick swings, and a spring is arranged between the ratchet and the barrel of the ratchet cylinder, so that the spring material pushes the spine outward, and the ratchet of the ratchet cylinder can often hold the state of the ratchet and the ratchet The pivoting portion does fit within the spine pocket 'to thereby ensure structural stability and enhance the certainty of the ringing action. [Embodiment] In order to enable the review committee to further understand and understand the purpose, characteristics and efficacy of the creation, please refer to the following [simplified description of the drawings] as follows: Structural improvement of the bicycle filament (4) For example, the first embodiment of the cage is preferably rotated from the first to the fourth, and the ratchet teeth 121 of the hub shell 10 press down the ratchets 32 of the ratchet cylinder 30. The ratchets 32 compress the springs 33. And pivoting the pivoting portion 321 of each of the ratchet blocks 32 relative to the respective ratchet pockets 313 to smoothly complete the pivoting motion. At this time, the ratchet teeth 121 of the hub shell 1 and the ratchet block 32 cannot be engaged, so that the hub shell 1〇 generates idling, and after the pressing operation of the ratchet block 32 is completed, the magazine 33 between the ratchet block 32 and the piercing member 312 of the tubular member 31 is reset, so that the ratchet blocks 32 can be normally returned to the state. In a state of meshing with the hub 1 ,, the deterministic certainty between the ratchet barrel 3 本 and the hub φ is improved. In addition, 'this creation is a C-shaped buckle 34 made of metal material, which not only has low manufacturing difficulty, but also has the existing products on the market, which can effectively reduce the cost; and the creation is made of a rigid C-shaped ring. The buckle 34 limits the position of the ratchet block 32 and limits the pivoting block 32 to only produce a limited angle of pivoting. At the same time, the ratchet block is normally pushed by the spring to push against the locking portion 322, and the pivoting portion 321 of the ratchet block 32 is again It can more reliably fit into the spine pocket 313, which not only increases the stability of the structure, but also ensures the actual operation of the pivotal motion of the ratchets 32; and also uses the hard c-shaped buckle 34, therefore even if this creation is not easy to produce elastic fatigue or malfunction under the repeated use of high frequency. Also, when the ratchet pocket 313 of the ratchet barrel 30 of the present invention is divided into a first spine pocket 313A and a second spine pocket 313B, and the first spine pocket 313A and the second spine pocket 313B is not equiangularly disposed, but is disposed by the first spine pocket 313A and the second spine pocket 313B, and each of the first spine pocket 313A and each of the second spine pockets 313B When the first rotation angle 01 has a rotation angle difference between the second rotation angle 7 M425782, the ratchet teeth 121 of the hub shell 10 can only be associated with each of the first spine pockets 313A or only each time. The ratchet block 32 in the second spine block groove 313B is meshed, and the difference in the rotational angle can exert a small rotation angle to drive the effect, thereby improving the driving efficiency.
