Abstract
The utility model belongs to the technical field of bicycle appliances, and particularly relates to an assisting device used for a deflated bicycle tire. The assisting device used for the deflated bicycle tire comprises a fixing base. An inner hole groove matched with the bicycle tire is formed in the center of the fixing base. Clamps are arranged on the two sides of the fixing base respectively. Sliding wheels are fixedly connected below the two ends of the fixing base respectively. The assisting device is simple in structure and reasonable in design, and damage, caused by direct friction between the deflated bicycle tire and the road surface, to an inner tube is avoided.
Description
Technical field
The utility model belongs to the technical field of bicycle articles for use, is specifically related to a kind of assistive device for the flat tire of bicycle.
Background technology
People day by day improve for environmental protection and healthy consciousness at present, and increasing people selects bicycle as the vehicle,
Not only environmental protection but also health, under the situation of city traffic congestion, bicycle has highlighted its advantage on the contrary simultaneously.But bicycle have a large drawback be exactly tire easily because gas leakage or prick tire and become flat tire, user can only shove along, and not only waste time and energy, and flat tire directly contacts on road surface, promotes to travel easily to cause wearing and tearing or the damage of the inner tube of a tyre on road surface.
Summary of the invention
The purpose of this utility model is the problem that causes inner tube of a tyre wearing and tearing or damage because of pavement friction for flat tire, and provide a kind of assistive device for the flat tire of bicycle, this assistive device simple in structure, reasonable in design, has avoided flat tire directly and pavement friction and cause the inner tube of a tyre also impaired.
The technical solution of the utility model is: a kind of assistive device for the flat tire of bicycle, comprise permanent seat, and the center of this permanent seat is provided with the internal bore groove matching with tire; Both sides at permanent seat are respectively equipped with clip; Below the two ends of permanent seat, be fixedly connected with respectively pulley.
Described pulley is fixedly connected with permanent seat by pipe link.
Described pipe link is expansion link, like this can adjustable pulley and permanent seat between distance, make user select suitable height according to s own situation, promote power-saving more.
Described cw angle between pipe link and the permanent seat of permanent seat front end is 140～150 °, and the cw angle between pipe link and the permanent seat of permanent seat rear end is 30～40 °.Test gained by Experiments of Machanics, in this angular range assistive device can with another wheel perfect cooperation, pusher's thrust least cost.
The length of described permanent seat is less than the diameter of cycle wheel.
The thickness of described permanent seat is greater than 1/3rd of cycle wheel radius.
The beneficial effects of the utility model are: the assistive device for the flat tire of bicycle described in the utility model, comprise permanent seat, and the center of this permanent seat is provided with the internal bore groove matching with tire; Both sides at permanent seat are respectively equipped with clip; Below the two ends of permanent seat, be fixedly connected with respectively pulley.When the tire of bicycle flat after, flat tire is stuck in the internal bore groove at permanent seat center, then the clip by permanent seat both sides again by clamping permanent seat on tire, user passes through the height of expansion link adjustable pulley apart from permanent seat according to s own situation, can carry out advancing, both convenient and time-saving laborsaving, can solve again flat tire and directly contact the problem that causes the inner tube of a tyre impaired with pavement friction.
In sum, the described assistant structure for the flat tire of bicycle is simple, reasonable in design, has avoided flat tire directly and road
Face rubs and causes the inner tube of a tyre also impaired.

Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in detail.
From accompanying drawing, can find out, a kind of assistive device for the flat tire of bicycle of the present utility model, comprises permanent seat 1, and the center of this permanent seat 1 is provided with the internal bore groove 2 matching with tire; Be respectively equipped with clip 3 in the both sides of permanent seat 1; Below the two ends of permanent seat 1, be fixedly connected with respectively pulley 4.
Described pulley 4 is fixedly connected with permanent seat 1 by pipe link 5.
Described pipe link 5 is expansion link, like this can adjustable pulley 4 and permanent seat 1 between distance, make user select suitable height according to s own situation, promote power-saving more.
Described cw angle between pipe link 5 and the permanent seat 1 of permanent seat 1 front end is 140～150 °, and the cw angle between pipe link 5 and the permanent seat 1 of permanent seat 1 rear end is 30～40 °.Test gained by Experiments of Machanics, in this angular range assistive device can with another wheel perfect cooperation, pusher's thrust least cost.
The length of described permanent seat 1 is less than the diameter of cycle wheel.
The thickness of described permanent seat 1 is greater than 1/3rd of cycle wheel radius.
When the tire of bicycle flat after, flat tire is stuck in the internal bore groove 2 at permanent seat 1 center, then the clip 3 by permanent seat 1 both sides again by clamping permanent seat 1 on tire, user passes through the height of expansion link adjustable pulley 4 apart from permanent seat 1 according to s own situation, can carry out advancing, both convenient and time-saving laborsaving, can solve again flat tire and directly contact the problem that causes the inner tube of a tyre impaired with pavement friction.
