New type description: [New technology field] The new type relates to a bicycle flower hub structure, especially a "bike flower hub left and right drive interchange structure", by the combination of its combination, The hub structure can be adapted to the interchange of the left and right chain of the performance bicycle. [Prior Art] Lu press, a bicycle hub structure is known, as shown in Figs. 10 and u, which includes: a mandrel (60), a flower hub (70), an actuating ring (10), and a spine. A sprocket wheel (9 〇) is formed, a mandrel (60) is provided with a plurality of bearings (61), and is placed in the flower hub (70) with a bearing (61) to form a pivotal positioning, a flower hub (7) 〇) The inner wall of the side end is integrally provided with a fixing seat (71)' and the inner edge of the fixing seat (8) is formed in a square concave and convex shape, and an operating ring (10) is placed at the inner end of the fixing seat (8), and is formed by the concave-convex surface (10). The inner wall of the operating ring (10) also has a square concave surface (82), and the ratchet disk (9〇) has two parts, a money (91) and a ratchet seat (10), and the ratchet seat (92) is opened. There are a plurality of ratchet slots (93), and springs (10) and ratchets (95) are placed in the ratchet slots (93), and then inserted into the flower valley (10) by the ratchet seat (10), the ratchet seat (10) is located inside the actuating ring (10) and the ratchet (10) is pushed by the spring (94) and the concave surface (82) of the inner wall of the outer top ring (8〇) is snailed at both ends of the flower (7〇) The lock has a fixing screw, thereby forming a self Combination of car hub assembly. When the bicycle rotates the ratchet disc (90), the ratchet (95) can bear against the concave surface (10) of the actuating ring (10), that is, the flower hub (10) can be rotated in the same direction as the M365850. Version _ can not drive the ratchet ί When the left f-key bar is interchanged with the right-hand chain, the ratchet is fine):) and...T eight\ I v/y~ for the different 7 your lawful fun (10) Rotating, it is known that the bicycle flower valley structure is applied to the performance bicycle ratchet (95) for positional interchange, so that the interchange effect of the performance chain and the right chain can be achieved. Looking at the above-mentioned conventional structure, it is not difficult to find that there are still some shortcomings due to the following: The left main part of the bicycle (1) and its spine are pressed against the inner wall of the actuating ring (10) by the spring (10). The flower is rotated to rotate, but the inner wall of the actuating ring (10) is a concave-convex surface (10) of the square-shaped bump, so that the contact area of the ratchet (5) is too small, and the structural strength is insufficient. ~ (2), the inner wall of the actuating ring (10) is a concave-convex surface (10) of a square convex block, so that the interference height of the ratchet tooth (95) is increased, that is, the volume of the moving ring (10) is large, causing the ratchet (95) to actuate The amplitude of the swing on the ring (10) is increased, and there is a lack of sensitivity. "(3) Its actuating ring (10) is placed at the fixed seat (8) of the flower hub (70), and the inner wall of the flower hub (7G) is axially positioned with the ratchet disk (9 turns), and the actuating ring is actuated. (8〇), the ratchet disk (10) is still in the proper gap, so that the operating ring (10) has a space for axial displacement 'that is easy to make the more (10)) and the actuating ring (10)), and the structure of the car is reduced. In view of this, the creator has been engaged in the manufacturing development and design of related products for many years, and the 'two tests. After detailed design and careful evaluation, the creators have finally achieved the practical use of M365850. This creation. , \ [New content] Technical problems to be solved: (1), the ratchet is pushed against the inner wall of the actuating ring by the spring, _ things (four) (four) she is like a convex surface, so that the spines The contact area of the tooth is too small, and the structural strength is insufficient. - (2) The inner wall of the actuating ring is the concave and convex surface of the square convex block, so that the resistance height increases, that is, the swinging amplitude of the moving 朿1^ is increased, Insufficient sensitivity. The clothing on the clothes and the ratchet disk form a valley and the number of flowers is fixed. At the same time, and through the inner wall gap of the flower hub, the movement of the production ring and the ratchet disk still have the space of the ship between the movable ring, which is easy to cause the wear of the plate and the clothes, Na Nahua Durability of the hub structure. Technical features of the problem: A bicycle flower hub left and right drive interchangeable structure, including: - flower comparison, a solid ring, a linkage ring, ratchets on the bicycle _ /, the ', and 'and the 'made' of the lining of the inner wall of the system is provided with a accommodating space, and the accommodating space of the accommodating space is arranged with Wei, concave and convex view card ditch, view two: The age of the young flower __, __ has a square concave joint, the mandrel passes through the accommodating space and is formed by a plurality of bearings to form a pivotal capacity at the flower/station, and the buckle is a C-shaped buckle , - the fixed ring system X of the concave and convex ring, and with the formation of the ability to engage the outer bump M365850 (10) 働] set with minus _, _ convex square:: '- linkage ring system is placed in the fixed ring The inside, and the concave formed by the outer wall: the second: the Γ bump is snapped and fixed, and the inner wall of the interlocking ring is formed with a unidirectional: ^ oblique tooth surface'- The ratchet member is formed with a toothed disc and a ratchet seat, and is sleeved on the mandrel with one hole, and the ratchet seat is accommodated in the arboring space of the flower valley accommodation space. The combined structure, thereby achieving the effect of the shifting of the shifting wheel into the surface of the L-shaped surface, the plurality of ratcheting grooves, the shape of the ratchet groove, the shape of the ratchet groove, the shape of the ratchet groove, and the shape of the ratchet = and the bottom end of the ratchet is provided with a card hole or a second ratchet hole, and the other is a miscellaneous (four) fitting, that is, the beauty of her version is empty. When the performance bicycle is used, the left and right keys are interchanged. When the time (such as the demand of the wire = ground), the ratcheting device is in the bicycle state of the right button, the handle is disposed in the first-spindle hole, and the ratchet is disposed in the second ratchet hole, and the spine is When the bicycle is smashed in front, it can resist the slanting of the interlocking ring and the shape of the teeth is arranged in the bicycle state of the left chain. When the combination is connected, the ring is placed in the direction of the flower hub towel, and the money is still ok. Combined with the _ ring block, and can form the oblique tooth surface of the interlocking ring to produce the other direction of the skew, and the ratchet seat red miscellaneous pieces and Gu, Weihe left bar bicycle, elastic parts change nr spine The perforation and the ratchet are placed at the first-spindle hole, and by the combination of the combination thereof, the same sri y1 (3) can be generated to make the flower hub structure suitable for the performance type. In the way, the left-hand chain and the right-hand chain of the eye-catching drought are 6 M365850. Compared with the effects of the prior art: () by the combination of the transformation 'can be matched with the left-hand chain of the performance bicycle', the right-hand chain is interchanged, and the slanting is simpler than the oblique tooth surface of the _ ring, the oblique tooth-shaped contradiction The area is larger than the conventional tooth-toothed area, thereby increasing the strength of the structure and increasing its durability. (-), its collar is a slanted tooth surface that is deflected in one direction, and The surface of the tooth surface and the ratchet of the wire are formed by the ratchet surface, and the height of the ratchet can be reduced by the oblique tooth surface, and the oscillating ring of the ring can be reduced to reduce the amplitude of the ratchet tooth to improve its sensitivity. (-) The fixed position is fixed on the concave and convex of the flower hub, and the interlocking ring is fixed at the inner end of the fixed%, and then the retaining member and the buckle member are formed on both sides, thereby preventing the fixed 5 clothes and the linked shouting from sliding. In this way, the fine friction and collision are reduced, and the rotation resistance of the ratchet member is reduced to increase the durability.

The toothed disc (51) is rotated, and the ratchet (54) in the ratchet groove (521) is externally shaped by the outer top of the elastic member (53) (here, the elastic member (10) is preset to the first ratchet a hole M365850 (522), and the ratchet (54) is disposed at the second ratchet hole (523), and the outer end of the ratchet (10) abuts against the oblique tooth surface (42) of the inner side of the interlocking ring (40), The ratchet member (5〇) cannot be rotated by itself, and the interlocking ring (10) and the fixing ring (3〇) are synchronized with the concave-convex surface (41) and the inner convex block (10), and the convex ring (3) outside the fixing ring (10) and the concave and convex portions The ring (10) is synchronized, that is, the ring (10), the fixed ring (10) and the flower valley (10) are all turned in the forward direction of the wheel. When the bicycle is in the bicycle line, the flower hub (10) turns into a forward rotation and interlocks the fixed ring. (30) and the interlocking ring (40), at this time, the ratchet (10) is pushed by the oblique tooth surface (10) to swing toward the elastic φ member (53) end, and the unidirectional driving flower (10) effect can be achieved by the above action. . When the performance bicycle is interchanged between the left chain and the right chain (for example, to meet the needs of the performance venue), the continuation is shown in Figures 6, 7, 8, and 9. The sixth and seventh diagrams are the spines. The tooth member (10) is disposed on the bicycle shape g of the right chain, and the combination method as described in the above paragraph is that the elastic member (53) is disposed on the first ratchet hole (522), and the ratchet (54) is disposed on the second ratchet. The hole (523), and the ratchet (54) can resist the oblique tooth surface (42) of the interlocking ring (40) when the bicycle is traveling forward, and the interlocking effect is formed, and then the figures 8 and 9 are the ratchet teeth. (50) The bicycle is placed in the state of the left-hand chain, and the combination of the hub structure is such that the interlocking ring (10) is placed in the flower hub (10) in the other direction, and the concave-convex surface (41) of the interlocking ring (10) is still The cam (32) can be engaged with the inner ring (10), and the oblique tooth surface (42) of the interlocking ring (40) can be deflected in another direction, and the device is at the ratchet seat (52). The employee (10) and the lung (54) are bicycles with a left chain, the elastic member (53) is changed to be disposed in the second ratchet hole (523), and the ratchet (54) is disposed in the first ratchet hole (522). ) by its group By changing the mode, the bicycle can be operated in the same way as the right button bar, so that the flower hub structure can be adapted to the interchange of the M365850 left chain and the right chain of the performance bicycle. Eight hunting the structure of the above specific embodiment can obtain the following benefits: (1) by the secret of the group port method, the left-hand chain and the right-hand button of the performance bicycle can be interchanged, and the ratchet (54) system Corresponding to the oblique tooth surface (10) of the interlocking ring (10), the oblique tooth-contact area is larger than the conventional square tooth-shaped contact area, thereby increasing the structural strength 'howling plus its resistance; (2) its Even pure (10) has a unilaterally skewed helical tooth surface (42) with a helical tooth surface (10) and a ratchet (10) at the ratchet seat (10)
