New description: [New technical field] This creation is about the "improvement of bicycle sprocket cover structure", especially the creation of a bicycle sprocket cover for wooden materials. [Prior Art] According to the prior art, the bicycle sewn cover is mainly a metal plate member, which not only has a low cost of 'four and a color single', but also conforms to the current user trend. In response to the above problems, the toothed disc cover of the non-metal plate metal piece appears on the market, which can solve the production cost problem, but the whole piece of wood board itself has no gap, and the expansion of the elastic force is not good. When the pressure is applied, it is easy to produce a problem of rupture; >1 and, in general, the surface color and texture of the wood slabs are also very simple - so that the selectivity of the lang is not diversified; Hey, the lack of the aforementioned conventional structures is really necessary to make progress. The creator is more careful than the current gambling structure, so he has been engaged in the production and marketing experience of related products, and has been thinking about the existing problems. After many improvements, he finally created a bicycle. The structure of the sprocket cover is improved. [New content] The main purpose of this creation is to provide a county that uses wood materials to be laminated, because the wood itself has a knife-like nature, and has a certain elasticity, which can avoid cracking due to the application of external force. Good age, can improve the overall structure of the bicycle gear plate cover using M373329 life. The other is to provide a bicycle sprocket cover structure with better safety for use. The purpose of this creation is to improve the structure of the toothed disc cover which is convenient for providing the age. In order to achieve the above purpose, the present invention proposes a bicycle sprocket cover structure improvement, which is composed of a spare part of the stencil and a plurality of locks; the stalk of the sprocket is combined with the _, so that the handle is connected to the sprocket The cover plate is fixed on the toothed disc by using each of the locks; and the cover plate is mainly affixed by two or more wooden boards, and the top and bottom surfaces of the wooden board are respectively covered with an outer skin layer. The 8th epidermis of the 8th Middle School is thick veneer, paper, sapwood or melamine. Wherein, the outer skin layer is a transfer layer. Among them, the wood board system is solid wood, plywood, laminated wood or plywood. Wherein, the outer skin layer is provided with a grain. Among them, the lock is a screw. The following description of the preferred embodiment of the present invention is further described below in order to enable those skilled in the art to practice the present invention to be implemented in accordance with the description of the present specification. [Embodiment] First of all, please refer to the first to eighth figures. This is a modified bicycle sprocket cover structure. It consists of a toothed cymbal, a crank 2 〇, and a 缕 M373329. The cover plate 30 of the empty portion 3 Ο 1 and a plurality of locking members 4 ; are formed; the crank 2 is coupled to the crank 2 at the center of the sprocket 10 so that the crank 2 〇 can be connected to the _ bell 1 Q ' and the cover 3 Q The paste parts 4 Q are fixed on the toothed disc 10 (as shown in the second and third figures); and the shoal cover 30 is mainly made up of two or more wooden boards 3, which are laminated The top and bottom surfaces of the 3 1 are respectively covered with an outer skin layer 32 (as shown in the fourth and fifth figures). • Where 'the outer skin layer 32 is thick veneer, paper, synthetic wood or a beautiful board. The outer skin layer 32 is a transfer layer. Among them, 'the far wood board 31 is solid wood, plywood, laminated wood or plywood. Wherein, the outer skin layer 32 is provided with a texture (as shown in the eighth figure). Among them, the lock 4 is a screw. With the above combination, please continue to refer to the first to eighth figures. The wooden cover 3 is not the main one. The main system is to stick a plurality of wooden boards first and then to the board 31. The top and bottom surfaces are respectively covered with a skin layer 32 (as shown in the fourth and fifth versions), so that it can be formed into the creation of Wei 3 0 (as shown in the third figure). It is simple and convenient, and the creation is mainly made of wood materials. The wood itself is recorded and has a certain elasticity, which can avoid the phenomenon of cracking due to the application of external force. Therefore, the overall structure is good and can be improved. The overall service life is practical. The assembly method of the creation cover 30 mainly uses the respective locks 4 to fix the cover 30 to the toothed disc (as shown in the second and third figures), so that the M373329 can be used as the toothed disc 1 The cover of the scorpion is used to prevent the rider from being accidentally scratched by the sprocket wheel, and has better safety in use and is practical. The wood board body 31 of the creation cover 30 can be glued and combined using a plurality of sheets (as shown in the sixth and seventh figures), and has the aforementioned effects. In addition, the outer cover of the creation cover 3 得以 can be made of thick veneer, paper, synthetic wood, melamine board or transfer layer, which can make the appearance of the cover of this creation 3 产生 appearance Appearance and artistic value, and it is possible to randomly change the outer layer of the outer layer of the φ road (as shown in the eighth figure), so that the value of the whole is improved and practical. ^ In summary, the structure of the bicycle sprocket cover of the present invention is improved, and the utility model is effectively improved. The main technical means of the existence of this cake, and the main technical means of this cake have not been found in any relevant publications. It is in line with the application requirements of the new patents, and the application is made according to law, and the application for patent rights is required.
