Description

The Electrical Bicycle emergency wheels

Technical field

The utility model relates to a kind of Electrical Bicycle emergency facility, specifically a kind of portable Electrical Bicycle emergency wheels.

Background technology

Before the utility model is made, similar Electrical Bicycle emergency wheels report of Shang Weijian or use.

Since Chinese Electrical Bicycle is born before 10 years, because of its comfortable convenient, economic environmental protection fashion is got up, the very fast whole nation in fashion, become a kind of new traffic tool that liked by the people, the particularly influence of factor such as register the license of the sclerosis of the rise of fuel price, road and motor bike restriction in recent years, make Electrical Bicycle substitute motor bike, bicycle gradually, the preferred traffic instrument of become the working of cities and towns working clan and countryside and peasantry, the outing of going out, visiting villagers' home.But, often ride and use Electrical Bicycle, can run into a kind of situation of embarrassment, be that the Electrical Bicycle inner tube of a tyre is punctured by the nail on the road, sharp stone or cullet and leaks gas, cause " casting anchor " in road, can't move, at this moment, the person of riding generally can only get off go-cart to the maintenance store repairing, but because the Electrical Bicycle vehicle body is heavier relatively, boost quite hard, and one the tunnel shift repair shop onto, rolls through some, usually can cause that originally the recoverable inner tube of a tyre is more serious because of rolling excessive breakage, finally can't repair and scrap; In addition, the cover tire of car is also easily big hinders " vigour " and reduction of service life.Especially go out by bike at night, as be on night shift, when night, returned evening, if it is damaged and " casting anchor " to run into wheel, repair shop does not do business again at night, the person of riding seeks help does not especially have door, complain incessantly.Therefore, be starved of a kind of Electrical Bicycle emergency wheels, solve the awkward situation that Electrical Bicycle " casts anchor ".

The purpose of this utility model provides a kind of simple in structure, convenient, cost of manufacture Electrical Bicycle emergency wheels low and easy to carry of mounting or dismounting.

The purpose of this utility model is achieved through the following technical solutions:

This Electrical Bicycle emergency wheels is made by a band steel

Shape is supported and a single-wheel is formed, and in the upper end of supporting individual through hole is arranged, and the slightly larger in diameter of through hole also is provided with a pinch device in the wheel shaft diameter of Electrical Bicycle in the upper end of supporting; There is a wheel shaft lower end of supporting, and single-wheel is installed on the wheel shaft, and the radius of the height of single-wheel lower edge greater than the Electrical Bicycle tire arrived at the through hole center.

Described support can be combined by upper support and lower support, and said upper support is the long flat structure of top band one through hole, and the slightly larger in diameter of through hole has an annular protrusion in the wheel shaft diameter of Electrical Bicycle at the middle part of upper support; Said lower support is that a band steel is made The shape structure, its upper end is provided with a flat recess, and the oad of the size of recess and the degree of depth and upper support matches, and can more closely be enclosed within on the upper support, and wheel shaft and single-wheel are arranged on the lower end of lower support.

The specific embodiment

As shown in Figure 1, the support 1 of the utility model Electrical Bicycle emergency wheels adopts band steel to be made into Shape, establish a through hole in the upper end of supporting 1, the slightly larger in diameter of through hole is in the wheel shaft diameter of Electrical Bicycle, establish one by a nut 2 and the pinch device that bolt 3 is formed in the upper end of supporting 1, nut 2 down hand weldings are at the correct position that supports 1 upper end and single-wheel 5 opposition sides, and bolt 3 is screwed in the nut 2 from bottom to top; A wheel shaft 4 is established in the lower end of support 1, and rubber wheels or synthetic plastics wheel are adopted in single-wheel 5, are installed on the wheel shaft 4, and the height of single-wheel 5 lower edges is arrived greater than 3 centimetres-5 centimetres of Electrical Bicycle tire radius in the through hole center.

As shown in Figure 2, said support 1 can be made upper support 6 and lower support 9 unitized constructions, upper support 6 is long flat structures of top band one through hole, the slightly larger in diameter of through hole is in the wheel shaft diameter of Electrical Bicycle, can in advance upper support 6 be separately fixed on the forward and backward wheel shaft of Electrical Bicycle, be provided with a steel annular protrusion 7 in the appropriate location, middle part of upper support 6, when upper support 6 is fixed on the Electrical Bicycle wheel shaft, the upper surface of annular protrusion 7 just in time is stuck in the lower edge of Electrical Bicycle axle beam, prevents upper support 6 rotations; Lower support 9 is that a band steel is made The shape structure, its upper end is provided with flat recess 8, the oad of the size of recess 8 and the degree of depth and upper support 6 matches, can more closely be enclosed within upper support 6 bottoms, and annular protrusion 7 lower surfaces of upper support 6 are contacted with flat recess 8 end faces of lower support 6, the weight of carrying and transmission Electrical Bicycle, wheel shaft 4 and single-wheel 5 are arranged on the lower end of lower support 9.

As shown in Figure 3, the pinch device of Electrical Bicycle emergency wheels, can also form by a rectangular ring set 10 and two screws 11, oblong ring set 10 can slide in the upper end of supporting 1, respectively be provided with a screw on the both sides of oblong ring set 10, screw 11 is screwed in the screw, tightens screw 11 and just ring set 10 can be fixed in the support 1, and make ring set 10 upper surfaces tightly be stuck in the lower edge of Electrical Bicycle axle beam, prevent to support 1 and rotate.

When reality is used, in case the Electrical Bicycle front tyre takes place to leak gas when causing " casting anchor ", if what adopt is Electrical Bicycle emergency wheels shown in Figure 1, need raise tire, pull down the nut on the Electrical Bicycle wheel shaft, the Electrical Bicycle emergency wheels is contained on the Electrical Bicycle wheel shaft, tightening nuts, and will support 1 lower edge that is pressed on the Electrical Bicycle axle beam with pinch device, prevent to support 1 rotation, after fixing emergency wheels, support the weight of Electrical Bicycle with emergency wheels,, change and to open Electrical Bicycle lentamente behind the emergency wheels and repair to maintenance point if front-wheel " casts anchor ", when rear tyre gas leakage causes " casting anchor ", change emergency wheels then very leggiero go-cart repair to maintenance point.

If employing compound type support 1, can in advance two upper supports 6 be separately fixed on the forward and backward wheel shaft of Electrical Bicycle, when the generation tire flat causes " casting anchor ", raise tire, directly be enclosed within on the upper support 6 lower support 9 of band single-wheel 5 just passable, thereby solved the difficult problem that the Electrical Bicycle tire flat " casts anchor ", therefore, had simple in structure, convenient, the cost of manufacture advantage low, easy to use and carry of mounting or dismounting.

The utility model Electrical Bicycle emergency wheels makes an amendment slightly, can also be used for the emergency wheels of motor bike.
