New description: [New technical field] The main part of this creation is the lock structure of the combination of the stalk and the thin cover. [Prior Art] % • Press, TWM35 employment number "Bicycle chain plate combined with protective 篕 structure" new patent • Revealed 'mainly in the - joint part - end extended external thread, - the end forms the internal thread, the external thread is matched -The nut is used to lock the gambling disc and the crank. The _ pattern is combined with a bolt to provide the key function of the key cover and the dragon group. This achieves the independent group of the toothed disc set and the protective cover, and does not interfere with each other. Advantage. ^ 'Innovative combination of internal appearance, _: can overcome the technical problems of the conventional crank, the toothed disc set and the protective cover interlocking with each other, but the following technical disadvantages are derived: Art No. It is found that, in combination with the (4) threaded bolts, the surface is recessed with a hexagonal hole for the hex wrench. The hexagonal hole is easy to cause dust or oil collapse, and the hoarding will cause the hex wrench to be completely unable to be pulled over time. The difficulty is missing. First, the hexagonal hole on the surface of the enlarged head of the snail is inconsistent with the flat large sprocket or protective cover due to the appearance of the hole. The third, the joint part is for the combination of the nut and the bolt at the same time. It depends on the manufacturer's special system. The idea that the universal joint piece cannot be used will increase the cost of the lock component of the crank, the toothed disc set and the retaining cover. . 3 M366503 Such as the above-mentioned various types of defects, it is obvious that there are necessary elements for improvement. The lock of the disc group and the protective cover [New content] This creation mainly provides the lock structure for the crank of the car and the toothed disc or the toothed disc and the protective cover. The purpose of the present invention is to provide a locking structure for the bicycle crank and the toothed disc or the toothed disc and the protective cover, and the object is to provide a toothed disc. And the locking structure for the protective cover. · Booking the crank and the chain or lock =::: The bicycle crank and the toothed disc or the toothed disc and the protective cover are: - screw, with the body and the part - the extension of the end extension _ The state has a screw-jointed portion, the end face of the different enlarged portion of the body, and a tool socket for a predetermined depth; and a kit, a surface sleeve-and a through-hole of the two ends are formed on the kit. The screwing part of the body screw lock; the 'kit can be put on the crank and the crossover, and then the screw and the kit=lock' can achieve the purpose of locking the crank and the toothed disc; if it is used for the component and the screw Outside the kit, the further step-by-step includes the central pumping = '彳' _ piece set domain dumping Wei (10), then _ piece 1 hole and protective cover, complex and snail: can achieve the locking function between the toothed disc group and the protective cover . ~ The effect is to the use of detailed structural space form, and other structures that are expected to be achieved.

The main structure comprises: a crank 10, one end extending radially from the plurality of claws Η, the surface of the claw Η is formed with a fixing hole 12; - The sprocket set 2G' is exemplified by the big clock 21 and the small spur 22, and the sprocket set can also be a single large sprocket. Or a large, medium and small three-toothed disc form; the large toothed disc 21 of the set of toothed discs 20 corresponds to the position of the claws, and is provided with a main toothed disc hole 211 and a sub-toothed disc hole 212, and the main toothed disc hole 211 is provided The small toothed disc 22 and the crank claw portion 221 of the toothed plate hole 221 are locked by a locking component, and the auxiliary toothed disk hole 212 is provided for the toothed disc and the protective cover, and is locked by a locking component. This creation is used to lock the locking components of the crank and the toothed disc group and the toothed disc set and the protective cover. If used in the crank and the toothed disc set, as shown in the third figure, the present invention comprises: a screw member 30 having a body portion 31 and a planar enlarged portion 32 extending at one end of the body portion, wherein the surface of the 'body 3' is formed into a male thread 311 in a spiral manner, and the body portion 31 is _ 312 of the majority portion 32, and the machine direction is the job-level (not To the tool sleeve hole 313, the figure is a hexagonal hole for the hexagonal hand; and the 40' surface is provided with a through hole for connecting the two ends, and the through hole is formed with a through hole. When the internal thread 411' is inserted into the body portion 31 of the screw member, the external thread: the screw thread is coupled to each other, and the sleeve 4G is formed on the periphery of the end surface, and the edge of the edge 42 is formed. The tool sleeve socket 421 (also available | M366503 IIS shape), the kit can also eliminate the retaining edge design, directly set the tool sleeve groove in the hole ^ square Γ 'As shown in the fifth figure' kit 4G one by one After the small toothed disc 22, the screw member 3 (the fixing hole 12 of the ^11 and the main toothed plate hole 211 of the large toothed disc 21) are rearward (Fig. The through hole 41 of the kit, the hex wrench turns the tool sleeve hole 313 of the body portion 31, and rotates the screw member 3 in the same direction toward the sleeve 4. The direction of the retaining edge 42 advances the S-locking purpose of the Qingmu field' Obtaining the combination of the toothed disc set 20 and the crank 10 and then gt; π is shown in the fourth figure, the locking component of the present invention, if used for the locking of the cover, for the operation of the chain of the toothed disc and the protective cover Empty (4) == Contains the screw 3 described in the third figure. The above-mentioned) is further included in the kit, and further includes a barrier member 50, which is a contact body of a thick thickness, and a central body (four) Referring to the sixth figure, after the above-mentioned sprocket set 2 〇 and the crank 1 〇 are independently locked, the re-blocking member 5G is placed between the tooth and the tilt (10), and will be separated by The shaft hole 51 and the auxiliary tooth hole 212 are in alignment with the coupling hole 61 of the protective cover, and the kit is worn by the pair of holes, the view 51 and the joint hole 61, and finally the body 31 of the screw 3G is worn. The through holes 41 of the human kit 4Q are interlocked with each other, so as to achieve the purpose of locking the toothed disc set 20 and the protective cover 60. The present invention uses the above-mentioned clerk elements to face the effect: M3 66503 The shape of the separation -, the plate hole of the # disk group, combined with the third Lin fourth figure recording and unloading effect. With the first Lai I Ling used to turn the components, the barriers (etc. ^ need to use the city to know the general The type of nut can be used, it can be protected: the group unloading process does not interfere with the function of the toothed disc group, compared with the previous technology, and the parts are combined, the cost advantage is greatly reduced. ★The screw of the locking element, The enlarged part is a flat design, which is not in the previous one, and the corner hole is -30, which can prevent the foreign matter from being smashed, and can also maintain a smooth consistency with the sprocket group view. The locking structure with the toothed disc or the money and the protective cover not only has the structure (4), but also has a significant entry into the red Wei, in line with the relevant requirements of the national patents, and the patent application is filed according to law.
