Abstract
The utility model relates to a connection rod block cover which comprises a cover body. The cover body is part of a cylinder. A cavity is formed in the cover body. The middle of the cavity is provided with a retaining ring which is arranged in the radial direction of the cover body. An opening is formed in the bottom of the retaining ring. The cover body is made of soft silica gel. The connection rod block cover is installed on a matched connection rod of a bicycle, and the problem that trouser legs of a rider are contaminated by a rusted connection rod when riding the bicycle is solved. The connection rod block cover is simple in structure, reasonable in design, low in cost, capable of being produced in mass and convenient and fast to detach and install.
Description
Technical field
The utility model relates to a kind of improvement of connecting rod assembly, particularly a kind of simple in structure, can prevent the connecting rod block cover that connecting rod is made trouser legs dirty.
Background technology
Bicycle is that the power of tread plate being born by connecting rod is passed to transmission shaft, and then drives driving chain running, finally realizes the running of wheel.Crankshaft end of connecting rod with transmission shaft for being fixedly connected with, because bicycle is for a long time in outdoor application, expose to the sun and rain and can cause junction to be got rusty, in the time of by bike when stretcher is during in lowermost end, rider's trousers trouser legs are trouser legs of making dirty with connecting rod grazing just often, and iron rust is difficult to again clean up.
Utility model content
The utility model object be in order to overcome the deficiencies in the prior art, provide a kind of simple in structure, can prevent the connecting rod block cover that connecting rod is made trouser legs dirty.
For achieving the above object, the technical solution adopted in the utility model is: a kind of connecting rod block cover, comprise cover body, and described cover body, for for a cylindrical part, has cavity in described cover body, and the middle part of described cavity is radially provided with clasp along cover body.
Preferably, described clasp bottom is provided with opening.
Preferably, described cover body is made by software silica gel.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
Connecting rod block cover described in the utility model can be installed on the bicycle connecting rod matching, described cavity size matches with crankshaft end of connecting rod profile, because described cover body is made by software silica gel, opening described opening is buckled in clasp on the transmission shaft being fixedly connected on connecting rod, clasp is fitted on transmission shaft, makes connecting rod block cover be difficult for dropping; When needs take off the connecting rod block cover of clearing up or more renewing, as long as be just a little firmly pulled outwardly and described connecting rod block cover can be taken off; Connecting rod block cover described in the utility model is simple in structure, reasonable in design, with low cost, can be mass, convenient to disassembly, and fine cleaning, can well solve rider by bike time connecting rod get rusty and cause the problem of making trouser legs dirty.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Accompanying drawing 1 is the front view of connecting rod block cover described in the utility model;
Accompanying drawing 2 is the cutaway view of connecting rod block cover described in the utility model;
Assembly drowing when accompanying drawing 3 is connecting rod block cover application described in the utility model;
Wherein: 1, cover body; 2, cavity; 3, clasp; 4, opening; 5, transmission shaft; 6, crankshaft end of connecting rod; 7, connecting rod; 8, groove.
The specific embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
As accompanying drawing 1,2 is depicted as a kind of connecting rod block cover described in the utility model, comprise cover body 1, described cover body 1, for being a cylindrical part, has cavity 2 in described cover body 1, and the middle part of described cavity 2 is radially provided with clasp 3 along cover body; Described clasp 3 bottoms are provided with opening 4; Described cover body 1 is made by software silica gel.
Assembly drowing while being applied on bicycle for connecting rod block cover described in the utility model as shown in Figure 3, cavity 2 sizes of connecting rod block cover described in the utility model match with the profile of the crankshaft end of connecting rod 6 of connecting rod 7 upper ends, after connecting rod 7 is fixedly connected with transmission shaft 5, the cover body 1 of connecting rod block cover is installed on the upper end of crankshaft end of connecting rod 6; Due to fluted 8 design on crankshaft end of connecting rod 6, in described groove 8, expose a part of transmission shaft 5, the internal diameter of the clasp 3 of connecting rod block cover described in the utility model equals the external diameter of transmission shaft 5, because described cover body 1 is made by software silica gel, the opening 4 of opening clasp 3 bottoms is buckled in clasp 3 on transmission shaft 5, makes connecting rod block cover be difficult for dropping; When needs take off the connecting rod block cover of clearing up or more renewing, as long as be just a little firmly pulled outwardly and described connecting rod block cover can be taken off; Connecting rod block cover described in the utility model is simple in structure, reasonable in design, with low cost, can be mass, convenient to disassembly, and fine cleaning, can well solve rider by bike time connecting rod get rusty and cause the problem of making trouser legs dirty.
Below be only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, within all dropping on the utility model rights protection scope.
