Description

M252834 g. Creation Instructions (l)-[Technical Field] This creation is related to a chain structure, which is a body connected to a pair of two outer chain pieces and the guard plate system. Innovative structure space type [Prior technology] According to the chain, the whole chain is composed of several groups of inner and outer link shafts constituted by a group of grooves, as well as the inner and outer links of each group. Directly impacted by external forces, an industry researcher has developed a protective plate member outer periphery, and then achieved a protective profit disclosure disclosed in No. 1 781 54. The structure of the protective plate is a separate type combined with the chain, so although it is combined with the chain The strength is not exhaustive and has not been improved; moreover, the combination adds another plate thickness, so the shortcomings of interference are actually its unpaired internal and external links and pivot joints. The structural features that form a swivel pivot that can cooperate with the chain teeth are due to the state of being penetrated with the outside world, resulting in the disadvantage of deformation. In view of this, it can be used to set the chain outside the chain. Its structural type is like a national patent (such as an attachment), but because this custom-made component can be protected by a set of components, the guard plate wants to protect the structural strength of the chain itself. Also that the outer dimensions of the chain will be more space is provided to increase its presence group readily improvement.

Therefore, in view of the problems existing in the above-mentioned conventional chain guards, how to develop a new structure with more ideal practicability is a breakthrough breakthrough that the industry needs to improve.

2. Creation explanation (2) There is a flaw in the combination strength with the chain and the lack of improvement in the structural strength of the chain itself. Technical characteristics to solve the problem: The chain is composed of a pair of inner and outer chain links, and the shafts and guard plates that pivot the inner and outer links of each group. Its technical characteristics are: It is a structural type that is integrally connected between one side of a pair of f outer links, and constitutes a shape of the body of the outer link of the protective plate. The shape of the body is η; and among them, each pair; the links can also be ^ ϋ A structural form formed by integral extension of one end of the outer chain piece, and a zigzag surface at the inner and ν phases, forming the inner chain piece which is a type that is one piece thicker than the outer chain piece. Contrast with the effect of the prior art ... 1 Provide an innovative chain structure space type in which the guard plate is integrally connected to one side of a pair of two outer links. 2. With the special improved design of the integrated protective plate, in addition to the original ft repeated power, its chain links are connected by one body of the protective plate, and the structural strength is increased, and the outer shaft is protected from deformation. Balanced driving force = the knife and the practical effect and purpose of keeping the shape flat and not expanding. [Implementation] In order that the reviewing committee members can further understand and understand the purpose, characteristics and effects of this creation, please cooperate with [Simplified Illustrations] as detailed below: First, please refer to Sections 1 and 2 As shown in Figures 3 and 4, this is a preferred embodiment of the body-type outer chain guard structure of the creative chain. The chain as a whole is composed of several pairs of inner links (10), outer links (20), and pivot joints. M252834 IV. Creation instructions (3) The shaft (30) and the guard (40) of the inner and outer links (10) (20) of each group are composed to form a ratcheting groove that can cooperate with the chain teeth and The inner and outer links (10) (20) of each group can be pivoted (30) as the pivot pivot pivot structure. The inner link (10) and the outer link (20) are provided with A hole (11) (21) is provided for the assembly of the aforementioned rotating shaft (30); it is characterized in that: the protective plate (4 0) is integrally connected to the two outer chain pieces (2 0) The structural type between the sides constitutes a gate shape in which the cross section of the guard plate (40) and the two outer link pieces (20) are integrated (see Figure 4 for details).

As shown in Figures 5, 6, 7, and 8, it is another preferred embodiment of the integrated outer chain plate guard plate structure of the creative chain. In this embodiment, the guard plate (4〇β) is a body. The two outer links (20B) connected to a pair-the structural features between the sides are the same as the previous embodiment; the difference lies in that each pair of inner links (10B) is also composed of each outer link (20B) The structure is formed by integrally extending one end, and the inner and outer links (1〇B) (2〇β) have a zigzag surface (50) at the junction, forming the inner link (1 〇Β) is more than the outer chain The plate (2β) is moved inward by a chain thickness type; by this, the three inner and outer chain plates (10B) (20B) and the guard plate (40B) will be an integrated chain element. The inner chain piece (丨 〇B) of the two chain elements will be pivotable

After arranging between the two outer chain pieces (20B) of another group of the same chain element, so that the through holes (11) (21) are opposite to each other, the shafts (30) can be inserted through the group and combined, and so on By combining several sets of chain elements, a chain finished product can be formed. Xi Yi supports the upper structure, in which the guard plate (40B) and two outer links (20b)

M252834 IV. Creation ia (4) The corner of the connection can also have an inverted U-shaped zigzag edge (6 0) protruding upward (Zen as shown in Figure 8). [Effect description] 1 · Between the lifting side and 2 · By borrowing the unique and deformed and flattened practicality of the chain guard plate to create specific refinements and modifications of the previous work, the function is added to provide an innovative chain designed by the integrated protection function. For a more balanced transmission force effect and purpose, the facts that God and principle should be included are as follows. The guard plate is an integrated structural space. In addition to the special capabilities of the guard plate, its chain can greatly increase the amount of knots. Distribution as well. The best practice of creation is the one who is familiar with this technique and covers this creation in the following application. Linked to the two outer links in pairs. Improve the design of the film by using the structure of the human body to change the patent norm, except for having a body connection of the original shield, to achieve protection of the shaft without maintaining flatness and expansion (the technical characteristics of this creation should be Without departing from the present and the modifications, and in the scope defined by these variations, the M252834 diagram is briefly explained.
