Description

Technical Field

[0001] The utility model relates to the field of transmission chains, in particular to an integrated parallel chain. Background Art

[0002] Chains are generally metal links or rings, often used for mechanical transmission and traction. Traction refers to chain-shaped objects used to block traffic passages (such as in streets, rivers, or at the entrances to harbors). Chains used for mechanical transmission can be divided into short-pitch precision roller chains; short-pitch precision roller chains; bent-plate roller chains for heavy-duty transmission; plate chains for cement machinery; and high-strength chains.

[0003] With the development of the times, there are more and more chain structures, and they have different characteristics according to different usage scenarios. There are now some parallel double-chain structure chains on the market. The chain links of this chain are made of four chain plates connected by a longer chain pin, which has a high tensile strength. However, due to the increase in the number of chain plates, the production cost has increased, and sufficient gaps need to be reserved between the chain plates to ensure flexibility, resulting in higher noise during use.

[0004] The technical problems to be solved by this application are: how to save production costs and how to reduce noise during use. Utility Model Content

[0005] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide an integrated parallel chain with low production cost and low noise in use.

[0006] The technical solution adopted by the utility model is: an integrated parallel chain, including outer chain plates and reinforcement chain plates, the two opposite ends of the outer chain plates are provided with chain pins for pinning the reinforcement chain plates, the two outer chain plates are arranged symmetrically, the reinforcement chain plate is located between the outer chain plates, and gear cavities are reserved between the two sides of the reinforcement chain plate and the corresponding outer chain plates, the top of the reinforcement chain plate is provided with a protective pad, and the two sides of the protective pad are provided with protective wings, and the protective wings are provided with tooth grooves for teeth to be inserted;

[0007] In the present invention, a reinforcing chain plate is directly added between the two outer chain plates. Since the reinforcing chain plate directly replaces the original two additional chain plates, the production cost can be reduced during processing and production. Moreover, since the reinforcing chain plate separates the two outer chain plates, the chain links of this structure can form a parallel chain with a double-chain structure. In addition, a protective pad with a tooth groove is provided on both sides of the reinforcing chain plate and between the two outer chain plates, so as to reduce the direct collision of the teeth of the driving gear with the integrated parallel chain, thereby reducing the noise during use.

[0008] In some embodiments, the two ends of the outer chain piece are respectively a pre-installed portion and a connecting portion, and the pre-installed portion and the connecting portion are an integrated structure.

[0009] In some embodiments, the spacing between the pre-installed portions on the two outer chain links is adapted to the total width of the connecting portions of the two outer chain links.

[0010] In some embodiments, a reinforced edge is provided on the top of the outer side of the outer link.

[0011] In some embodiments, the protection pad and the reinforcement chain pieces form a semi-enclosed structure, and the heights of the protection pad and the reinforcement chain pieces are equal to the height of the outer chain pieces.

[0012] The beneficial effects of the present invention are:

[0013] (1) In the present invention, a reinforcing chain plate is directly added between the two outer chain plates. Since the reinforcing chain plate separates the two outer chain plates, the chain links of this structure can form a parallel chain with a double-chain structure. The original two additional chain plates are directly replaced by the reinforcing chain plate, thereby reducing production costs during processing and production.

[0014] (2) In the present invention, a protective pad with a tooth groove is provided on both sides of the reinforcement chain plate and between the two outer chain plates, so as to reduce the direct collision of the teeth of the driving gear with the integrated parallel chain, thereby reducing the noise during use.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figures 1 to 5 The utility model provides a technical solution: an integrated parallel chain, including an outer chain plate 1 and a reinforcement chain plate 2. The two opposite ends of the outer chain plate 1 are provided with chain pins 3 for pinning the reinforcement chain plate 2. The two outer chain plates 1 are arranged symmetrically, and the top of the outer side of the outer chain plate 1 is provided with a reinforcement edge 12. The reinforcement edge 12 reinforces the single outer chain plate 1 while allowing the outer chain plate 1 to maintain an upright posture during assembly, thereby facilitating production and processing. The reinforcement chain plate 2 is located between the outer chain plates 1, and gear cavities 20 are reserved between the two sides of the reinforcement chain plate 2 and the corresponding outer chain plates 1. The reinforcement chain plate 2 between the two outer chain plates 1 separates the two outer chain plates 1 and makes the single chain link they form an integrated parallel chain. Compared with the prior art that directly adopts the double-link parallel connection method, this structure has lower production cost and more compact structure.

[0023] See also Figures 1 to 5 The two ends of the outer link 1 are respectively a pre-installed portion 10 and a connecting portion 11. The pre-installed portion 10 and the connecting portion 11 are an integrated structure. The spacing between the pre-installed portions 10 on the two outer link plates 1 is adapted to the total width of the connecting portions 11 of the two outer link plates 1. When the outer link plates 1 are connected into a chain, the outer link 1 in the next position can insert the connecting portion 11 into the pre-installed portion 10 on the previous outer link plate 1, thereby forming a compact tripod-shaped structure. Compared with the existing connection structure, the number of parts is reduced, the degree of integration is higher, and the tensile force bearing capacity of the integrated parallel chain is improved.

[0024] See also Figures 1 to 5 A protective pad 21 is provided on the top of the reinforced chain plate 2, and protective wings 22 are provided on both sides of the protective pad 21. The protective wings 22 are provided with tooth grooves 23 for inserting teeth. The protective pad 21 with the tooth grooves 23 can insert the teeth of the driving gear, thereby preventing the teeth of the driving gear from directly contacting the outer chain plate 1 and the reinforced chain plate 2. A semi-enclosed structure is formed between the protective pad 21 and the reinforced chain plate 2.

[0025] The working principle and usage process of the present invention are as follows: First, the two outer chain plates 1 and the reinforcement chain plate 2 with the protective pad 21 in the chain are pinned together by the chain pin 3 to assemble a single chain link. During assembly, the outer chain plate 1 can be kept in a vertical state by the reinforcement edge 12.

[0026] Subsequently, several chain links are connected end to end in sequence through the chain pins 3 to form a complete chain. When the chain links are connected at the end, the connecting portion 11 between the two outer chain plates 1 in the next position can be inserted between the pre-installed portions 10 of the two outer chain plates 1 in the front.

[0027] Then, the protective pad 21 with the tooth groove 23 can insert the teeth of the driving gear, thereby preventing the teeth of the driving gear from directly contacting the outer chain plate 1 and the reinforcement chain plate 2. After the integrated parallel chain is assembled, it forms a double-chain parallel chain structure, and the reinforcement chain plate 2 directly replaces the original two additional chain plates, thereby reducing production costs during processing and production.

[0028] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
