Abstract

The utility model cuts off a ring shape seal inner tube usually utilized in a bicycle tire or an auto bicycle tire into omega shape, a concave and a convex conical port closed connector are respectively arranged on two cut-off ports to form an ohm shape movable union inner tube which can be mounted or dismounted without needing dismounting a wheel shaft and a chain.

Description

A kind of ohm of shape movable joint inner tube of a tyre

Affiliated technical field:

The utility model relates to a kind of ohm (Ω) shape movable joint inner tube of a tyre that traditional bicycle, motorcycle tyre tube are changed.

Background technology:

Since bicycle, motor bike came out, its employed tire construction was cover tire the inside dress inner tube of a tyre basically.Though now have the considerable part motor bike to adopt tubeless vacuum tire, but still have the motor cycle tire about 70% to have the inner tube of a tyre.Traditional inner tube of a tyre all is ring seal structure (or claiming round, pipe round sealed structure) basically, because its balance is good, so continued to use so far more than 200 year.Yet, be familiar with the people of bicycle, motor cycle tire repairing technique, always all can feel to have inconvenience, be exactly when the installation or removal inner tube of a tyre, wheel shaft, chain even the whole tire of wheel must be unloaded.

Summary of the invention:

Bicycle, motor bike in case blow out or leak gas, are difficult to change when long-distance running.Particularly use in a large number in recent years, dark Electrical Bicycle popular to people since trailing wheel texture ratio ordinary bicycle complexity many, change the inner tube of a tyre (trailing wheel), especially trouble very.The utility model is exactly the above-mentioned inconvenience at the traditional endless sealing inner tube of a tyre, does the breakthrough of " o ", is about to the original ring seal inner tube of a tyre and cuts off, be provided with at the fracture two ends one protruding one recessed two be connected the osed top joint each other.The inner tube of a tyre of such two joints when not docking is " Ω " shape, so be referred to as the ohm-type movable joint inner tube of a tyre.As long as the joint at these inner tube of a tyre two ends is docked, just formed the ring seal structure of traditional inner tube of a tyre during use, when installing, dismantling the inner tube of a tyre or tire patching, the replacing inner tube of a tyre, just made things convenient for manyly, need not again wheel shaft, chain etc. to be unloaded.

Description of drawings:

Fig. 1 is the structure cutaway view of the interior sicula of Ω type in the utility model.Among the figure 1, Ω type inner tube of a tyre sicula, 4, valve.

Fig. 2 is the movable joint cutaway view in the utility model.Among the figure 1, Ω shape inner tube of a tyre sicula, 2, the male-tapered joint, 3, the inner conical joint

The utility model is to beat to open a gap on the basis of traditional inner tube of a tyre ring seal structure, make the inner tube of a tyre become " Ω " type, and the breach two ends are designed to two tapers (outer cone, an inner cone) closed port joint, make and install or can dismantle flexibly and dock during patch an inner tube.

The specific embodiment:

After the Ω shape inner tube of a tyre docks, revert to the ring seal structure again, unaffected for the air pressure, leak tightness and the balance that make the inner tube of a tyre, the utility model specific embodiment is as follows:

One is that each of two tapering joint male-tapered joints (2) and inner conical joint (3) is self-enclosed, can not produce other leakage-gaps like this when butt joint; The 2nd, the inner tube of a tyre still is a single-piece, and unification is inflated by a valve (4).The air pressure that fills into is same, according to relevant equilibrium of pressure theorem, whole balancing of tyre, bears pressure and in-use performance can not be affected.

Claims

1. ohm shape movable joint inner tube of a tyre, form by " Ω " shape inner tube of a tyre sicula (1), male-tapered joint (2) and inner conical joint (3), it is characterized in that: become " Ω " shape inner tube of a tyre sicula (1) after the inner tube of a tyre sicula of ring seal is cut open, one end of otch is by male-tapered joint (2) sealing, and the other end is docked by inner conical joint (3).

2, the ohm-type movable joint inner tube of a tyre according to claim 1 is characterized in that: the conical design of osed top separately of the joint at ohm-type sicula two ends, the convergence part of inner conical joint (3) and male-tapered joint (2) is divided into concavo-convex taper fit.
