Because the first closed surface and the second closed surface are tightly abutted together after being inflated, the whole inner tube has no gap part, and the air pressure of each part can be approximately the same, so that the tire does not feel bumpy during the driving process.
In order to realize such a break-away structure, several specific embodiments are provided in this embodiment:
example 1
Referring to fig. 1 and 2, a break-away inner tube includes: the two ends of the strip-shaped inner tube carcass are respectively provided with a first joint 11 and a second joint 12; the free ends of the first joint 11 and the second joint 12 are respectively provided with a first closed surface 111 and a second closed surface 121, and the free end of the second joint 12 also extends out of a sleeve 122 along the length direction of the inner tire body;
the first joint 11 and the second joint 12 are butted through a sleeve 112 to splice the strip-shaped inner tube body into an end-to-end inner tube.
In this embodiment, the first sealing surface 111 and the second sealing surface 121 are in a mutual insertion type connection relationship in an uninflated state, and as a simple replacement, the first sealing surface 111 and the second sealing surface 121 may be directly abutted without an insertion relationship, which belongs to a simple replacement of this embodiment and is not described again.
In order to realize the insertion relationship between the first closing surface 111 and the second closing surface 121, the second closing surface 121 is a slot. The first closed surface 111 is used for connecting a first plug 1111 and a second plug 1112 along the length direction of the inner tube carcass, and when the first plug 1112 is inserted into the slot, the second plug 1112 is arranged in the sleeve 122 to splice the strip-shaped inner tube carcass into an end-to-end inner tube.
Specifically, the first plug 1111 and the second plug 1112 have a first air cavity 1113 and a second air cavity 1114 which are communicated with each other, and a third air cavity 123 is arranged between the groove wall of the slot and the inner wall of the second connector 12 along the radial direction; the first air cavity 1113, the second air cavity 1114 and the third air cavity 123 are respectively communicated with an inflation cavity of the inner tire body. Therefore, when the inner tire body is inflated, the first plug 1111, the second plug 1112 and the inserting groove can be expanded along the radial direction, the first plug 1111 and the inserting groove are abutted and tightly matched after being expanded, the second plug 1112 is tightly matched with the inner wall of the sleeve 122 after being expanded, and the sleeve 122 cannot be actively expanded in the inflating process, so that the second plug 1112 and the first plug 1111 are clasped in the sleeve 122 by the sleeve along with the expansion of the second plug 1112 at any time. And the existence of the third air cavity 123 enables the slot to be extruded along the radial upper and lower sides in the expansion process, so that the slot and the first plug 1111 can be fully held tightly. As shown in fig. 9 and 10.
More specifically, the slot wall of the slot is connected to the wall of the sleeve 122 by a limiting surface 124. The first plug 1111 and the second plug 1112 are connected through a first limit mating surface 1115, and the second plug 1112 is connected with the side wall of the first connector 11 through a second limit mating surface 1116;

The two limit matching relations can provide clear prompt for the plugging process, and the situation that the user is inserted too shallowly or deeply in the plugging process is avoided.
In this embodiment, in order to reduce the problem of stress concentration, the slot is an arc-shaped slot, and the slot, the limiting surface 124, and the cylinder wall of the sleeve 122 are transited through an arc angle; in this embodiment, a section of the slot along the axial direction is a tapered arc surface, and as a simple alternative in this embodiment, the section of the slot along the axial direction may also be one of an arc surface and a long-strip arc surface, or a combination of the above various arc sections. As shown in fig. 3-8.

The following preferred designs are also provided in this example: the sidewall of the sleeve 122 is 50% -70% of the sidewall thickness of the inner tire body. Where the sidewall thickness of the sleeve 122 and the sidewall thickness of the inner tire carcass are both widths in the uninflated state. The purpose of this arrangement is that the sleeve 122, after having superimposed the thickness of the second plug 1112, can be the same as the sidewall thickness of the tire carcass, thereby avoiding a bumpy feel during travel due to uneven thickness.
The length of the sleeve 122 is 5-10mm greater than the cross-sectional width of the inner tire carcass. This ensures that the sleeve 122 has a depth such that the second spigot 1112 is not easily released from the sleeve 122 and slides off.
The section of the slot along the axial direction is an arc-shaped surface, and the ratio of the arc length of the slot to the section perimeter of the inner tire body is larger than the expansion ratio of the inner tire body after being inflated.
Specifically, the section of the slot along the axial direction is an arc-shaped surface, and the arc length of the slot is more than 120% of the section perimeter of the inner tire carcass. The purpose of this is to make the slot possess certain length, make it be difficult to break after the inflation is stretched.
In this embodiment, the outer walls of the first plug 1111 and the second plug 1112 and the inner wall of the sleeve 122 are frosted surfaces, respectively, so as to increase the friction force of the plugging portion. Meanwhile, the inner tube is provided with salient points or patterns for increasing friction force on the outer wall, and the positions of the salient points and the patterns correspond to the holding positions of a user during the insertion of the inner tube.
The embodiment also provides a tire, which comprises an inner tube, an outer tube and a rim; the inner tube is a break-off inner tube as described above. After the inner tube is used, the time for replacing the inner tube can be shortened to five minutes from the traditional half hour, the efficiency for replacing the inner tube is greatly improved, and the tire using the inner tube has no bumpiness in the driving process and high comfort level.
