Abstract

The invention relates to a strip-type quick-mounting bicycle inner tube, which comprises an inflating valve and a tube body, wherein the tube body is composed of a hollow cylinder, and a cup-shaped ring-type convex seal head and a cup-shaped ring-type concave seal head which are fixedly arranged at two ends of the hollow cylinder; an inwards concave conical counter bore is fixedly formed in the inclined end surface of the cup bottom of the concave seal head; a conical boss is fixedly arranged on the inclined end surface of the cup bottom of the convex seal head; two ends of the tube body are connected with each other to form a ring when the conical boss extends into the conical counter bore, and are in seamless smooth butt joint under the filling action of the inclined end surfaces of the two seal heads after the inner tube is inflated, and thus the effect the same as that of a traditional sealed inflation inner tube can be achieved; the two ends of the inner tube can be separated when the inner tube is deflated, so that the operation of manually taking out the inner tube and replacing for a new one can be performed without detaching a whole wheel assembly by virtue of a special tool. The strip-type quick-mounting bicycle inner tube has the obvious advantages of reasonable and simple structure, and convenience, flexibility and maneuverability in use, and is universal and can be exchanged with an existing common inflating inner tube, thus having high economic practicality.

Description

A kind of strip fast-assembling type bicycle tube

Technical field

The present invention relates to a kind of vehicle air filling type inner tube of a tyre, particularly a kind of needs uses tool ejector wheel and strip fast-assembling type bicycle tube that is manually actuated, that complete replacing or maintenance.

Background technology

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, place under repair as required or the operation of the integral replacing inner tube of a tyre, 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, owing to needing specialized maintenance personnel to rely on special tool just can carry out upgrading or maintain the operation of the inner tube of a tyre, though cause with car person just in case there is inner tyre leakage accident in traveling in the wild on the way time when there being spare tyre also helpless, be absorbed in passive predicament.Thus, there is structure generally and owe rationally, upgrade or maintain inconvenient defect 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 object of the invention is to overcome the in use existing maintenance of the existing closed circular filling gas bicycle inner tube of a tyre and change inconvenient deficiency, providing a kind of does not need to dismantle whole vehicle wheel component and can take out by hand, carry out easily maintaining or the strip fast-assembling type bicycle tube of replacement operation.

Strip fast-assembling type bicycle tube main body of the present invention 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, the circular cup conformed to the external diameter of described strip hollow cylinder by external diameter and upper band gradient B are the inclined end face of 1-15 degree, be thicker than at the bottom of the closed cup of cup wall thickness and form, wherein: the cup bottom face of described female end socket is fixedly installed the concave enlarging shape tapered centre counterbore that taper angles A is 1-15 degree, 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, in addition, described male end socket, female end socket and described hollow cylinder are made up of homogeneous material, concave enlarging shape tapered centre counterbore on described male end socket and 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 zero-lash technique chamfering R between contact surface.

During work, strip fast-assembling type bicycle tube of the present invention is stretched to be placed in described concave enlarging shape tapered centre counterbore by described evagination hollow form cone-shaped nib and is interconnected into ring-type, is 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.

Based on the strip fast-assembling type bicycle tube of the present invention of above-mentioned design, because 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, guarantee that junction, end is in softness all the time, there is the conventional sense with 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, strip fast-assembling type bicycle tube overall structure of the present invention is reasonable and simple, easy to use and flexible, motor-driven, 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.
