Abstract
The utility model discloses a chain cover subassembly of bicycle, including chain cover and chain lid, the periphery of chain cover is equipped with the banding, and chain cover and chain lid dress even still include anticreep spare and strengthening rib subassembly, the banding inboard fixed connection of anticreep spare and chain cover, and have rubber spare on the anticreep spare, and an organic whole is made at the middle part of strengthening rib subassembly and chain cover, the strengthening rib subassembly includes peripheral frame and three strengthening ribs that are located peripheral frame, three strengthening rib cross arrangement. The utility model discloses structural strength is high, avoids the chain to take off the tooth.
Description
Technical field
The utility model relates to a kind of protective device of cycle chain, especially a kind of chain case assembly of bicycle.
Background technology
The closed chain cover of current bicycle is mainly in order to protect cycle chain and sprocket wheel to stain from Hui Cheng; reduce the wearing and tearing of transmission; greasy dirt is avoided to be stained with on the trousers of user; the structural strength of current closed chain cover is poor, and at rugged sections of road, chain can shake; chain is often caused to take off tooth; after chain takes off tooth, chain cover and chain lid need dismounting, inconvenient.
Summary of the invention
It is high that the purpose of this utility model is to provide a kind of structural strength, avoids chain to take off the chain case assembly of the bicycle of tooth.
In order to achieve the above object, the technical solution of the utility model is: a kind of chain case assembly of bicycle, comprise chain cover and chain lid, the periphery of chain cover is provided with edge sealing, and chain cover and chain mount cover and connect, also comprise anti-falling piece and reinforced rib assembly, anti-falling piece is fixedly connected with inside the edge sealing of chain cover, and anti-falling piece has Rubber Parts, and one is made at the middle part of reinforced rib assembly and chain cover, described reinforced rib assembly comprises peripheral frame and is positioned at three reinforced ribs of peripheral frame, three reinforced rib arranged crosswise.
After adopting said structure, described anti-falling piece is arc structure.
After adopting said structure, also comprise rotating shaft cylinder, rotating shaft cylinder and chain cover make one.
After adopting said structure, because anti-falling piece of the present utility model is fixedly connected with inside the edge sealing of chain cover, and anti-falling piece has Rubber Parts, therefore bicycle travels at grading roads, the Rubber Parts on anti-falling piece can not with chain contact, if travelled on rugged road, chain shakes, Rubber Parts will hinder chain to shake, and plays backstop action, prevents chain from taking off tooth.And reinforced rib assembly comprises peripheral frame and is positioned at three reinforced ribs of peripheral frame, three reinforced rib arranged crosswise, therefore strengthen the structural strength of chain cover, prevent chain cover to be impacted distortion, raising the utility model service life.
Accompanying drawing explanation
Fig. 1 is exploded view of the present utility model.
Detailed description of the invention
The embodiment provided below in conjunction with accompanying drawing is described in further detail the utility model.
Shown in Figure 1, a kind of chain case assembly of bicycle, comprise chain cover 1 and chain lid 2, the periphery of chain cover 1 is provided with edge sealing 1-1, chain cover 1 and chain lid 2 load, also comprise anti-falling piece 3 and reinforced rib assembly 4, anti-falling piece 3 is fixedly connected with inside the edge sealing 1-1 of chain cover 1, and anti-falling piece 3 has Rubber Parts 5, and reinforced rib assembly 4 makes one with the middle part of chain cover 1, described reinforced rib assembly 4 comprises peripheral frame 4-1 and is positioned at three reinforced rib 4-2 of peripheral frame 4-1, three reinforced rib 4-2 arranged crosswise.
Shown in Figure 1, described anti-falling piece 3 is arc structure, and arc structure can shorten the distance between Rubber Parts 5 and chain, smooth-riding surface travel Rubber Parts 5 not with chain contact, when chain shakes, Rubber Parts 5 just in time plays backstop action, prevent chain from taking off tooth, save the use material of anti-falling piece 3.
Shown in Figure 1, also comprise rotating shaft cylinder 6, rotating shaft cylinder 6 and chain cover 1 make one, and in order to protect front-wheel main shaft, rotating shaft cylinder 6 can well protect front-wheel main shaft, prevents dust to be attached on front-wheel main shaft, improve service life.
Shown in Figure 1, inside anti-falling piece of the present utility model 3 and the edge sealing 1-1 of chain cover 1, travel in smooth-riding surface Rubber Parts 5 not with chain contact, when chain shakes, Rubber Parts 5 just in time plays backstop action, prevents chain from taking off tooth.And reinforced rib assembly 4 makes one with the middle part of chain cover 1, described reinforced rib assembly 4 comprises peripheral frame 4-1 and is positioned at three reinforced rib 4-2 of peripheral frame 4-1, article three, reinforced rib 4-2 arranged crosswise, improve the structural strength of chain cover 1 of knowing clearly, prevent chain cover 1 to be impacted distortion, improve the utility model service life.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
