Traditional bike tyre is all combined by circular cover tire and closed circular inflated inner tyre and forms, in the assembled state, wrap up the inner tube of a tyre by cover tire, be inlaid in the vehicle wheel component that wheel rim is formed and be mounted on the forward and backward forked type wheel carrier of bicycle by wheel shaft.When the inner tube of a tyre leak gas for some reason, need repairing maintenance or change time, must first special tool be relied on to be disassembled from forked type wheel carrier by whole vehicle wheel component by specialized maintenance personnel, then could peel cover tire unobstructedly, take out the inner tube of a tyre, carry out as required keeping in repair or the operation of integral replacing, special tool finally also must be relied on to be recovered to be installed on forked type wheel carrier by vehicle wheel component, and action is loaded down with trivial details, time-consuming requires great effort again.And, rely on special tool just can carry out upgrading owing to needing specialized maintenance personnel or the operation of the maintaining inner tube of a tyre, though cause with car person just in case when travel on the way there is inner tyre leakage accident time when there being spare tyre also helpless, be absorbed in passive predicament.Thus there is the defect that inconvenience was owed rationally, and upgraded or maintained to structure generally in the existing closed circular filling gas bicycle inner tube of a tyre, considers all to owe desirable from practicality and economy point.
Summary of the invention
The purpose of this utility model will overcome the in use existing maintenance of the existing closed circular filling gas bicycle inner tube of a tyre and change inconvenient deficiency, provides a kind of and can take out by hand, carries out easily maintaining or the practical bicycle fast-assembling inner tube of a tyre of replacement operation.
Practical bicycle fast-assembling inner tube of a tyre main body of the present utility model includes casing and is arranged on the tire tube valve on casing, be characterised in that described casing main body is open strip, the strip hollow cylinder of tire tube valve is provided with from above, be fixedly installed on the male end socket on hollow cylinder end and be fixedly installed on the female end socket formation on another end of hollow cylinder, described male end socket and female end socket main body all cup-shaped circular, conformed to by the external diameter of external diameter with described strip hollow cylinder, wall thickness is at least the circular cup of 1.5 times of hollow cylinder wall thickness and upper band gradient B is formed at the bottom of the closed cup of the inclined end face of 1-15 degree, wherein: the cup bottom face of described female end socket is fixedly installed the concave enlarging shape center cone that taper angles A is 1-15 degree
shape counterbore,the cup bottom face of described male end socket is fixedly installed and assembles with described concave enlarging shape tapered centre counterbore the evagination hollow form cone-shaped nib conformed to, the rim of a cup of described circular cup arranges in inner contracting stepped, is made up of contracting shape rim of a cup edge in spacing dogging shoulder and external diameter conform to the internal diameter of hollow cylinder, in addition, described male end socket, female end socket and described hollow cylinder are made up of homogeneous material, described male end socket and the concave enlarging shape tapered centre counterbore on female end socket and the corner edge of outer gibbosity cone-shaped nib be provided be convenient to non-resistance enter position and enter position after the technique chamfering R that contacts of gapless face.
In the assembled condition, the end of described hollow cylinder is bonded on inner contracting shape rim of a cup edge by the spacing dogging shoulder on circular cup rim of a cup described on male end socket, female end socket is spacing, reliably sheathed.
During work, the practical bicycle fast-assembling inner tube of a tyre of the present utility model by described cone-shaped nib stretch be placed in spacing in described cone shaped countersink, be interconnected into ring-type, be placed in cover tire die cavity, and wrapped up by cover tire and be positioned on wheel rim, after inflation two ends end socket end face described technique chamfering R and on fit tightly under the combined action filled up with 1-15 degree inclined end face, gapless smoothly docks, and has effect equal with traditional closed inflatable inner tube; And when needs are changed or maintain the inner tube of a tyre, not needing to dismantle whole vehicle wheel component by special tool with car person namely can direct cover tire under peel manually, inner tube of a tyre two ends can be made after venting to be separated, to take out, carry out demand-driven easily, and carry with car under folded state after venting, for subsequent use or send and repair.
The utility model based on above-mentioned design practical bicycle fast-assembling inner tube of a tyre, because the rim of a cup of circular cup arranges in forming inner contracting by contracting shape rim of a cup edge in spacing dogging shoulder and external diameter conform to the internal diameter of hollow cylinder stepped, there are two between hollow cylinder and circular cup and join faying face, insertion reinforcement process is adopted to realize reliable interconnect, be conducive to Simplified flowsheet, enhance productivity, and the positive technique effect that connection is more reliable, guarantee more long service live can also be brought, casing is arranged to open strip, it is skewed that docking end face is arranged to 1-15 degree, assembling counterbore and plush copper are arranged to taper, and corner edge is provided with technique chamfering R, both be convenient to casing two ends and under non-resistance state, position can have been entered fast, and naturally dock smoothly under inflated condition after docking, between fitting surface, gapless fits tightly, junction, end is in softness all the time, without the mode of operation of extra frequent friction, guarantee to have and traditional closed inflatable inner tube equivalent efficacy, be convenient to again user when changing the inner tube of a tyre, do not need the professional that seeks help, do not need to dismantle whole vehicle wheel component by special tool yet, do not limit by operating environment, manual operations can be carried out on one's own initiative as required at any time, save time, laborsavingly to facilitate again, also to be convenient in the deflated condition folding carries, for subsequent use.Therefore, reasonable and simple, the easy to use and reliable operation of strip fast-assembling type bicycle tube overall structure of the present utility model, and with existing common inflatable tire, there is general, interchangeability, and thus economical and practical, be the desirable renewal product of existing common inflated inner tyre.
