Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1 to 4, the present embodiment provides a detachable bicycle auxiliary wheel support, including a framework structure 11, one end of the framework structure 11 is installed on a rear wheel installation shaft 15 of a bicycle and the framework structure 11 is fastened on the rear wheel installation shaft 15 through a locking nut 14, an auxiliary wheel is installed at the other end of the framework structure 11, a first through hole 12 and a guide channel 13 are arranged on the framework structure 11, the guide channel 13 is communicated with the first through hole 12, the diameter of the first through hole 12 is greater than the diameter of a circumscribed circle of the locking nut 14, the width of the guide channel 13 is less than the diameter of an inscribed circle of the locking nut 14, and the width of the guide channel 13 is greater than the diameter of the rear wheel installation shaft 15.

In this scheme, lock nut 14 is installed on rear wheel installation axle 15 and unscrews lock nut 14, then lock nut 14 passes skeleton texture 11 through first through-hole 12, then adjusts skeleton texture 11's position and makes rear wheel installation axle 15 be arranged in guide channel 13, screws up lock nut 14 at last to the realization is to skeleton texture 11's installation.

The scheme has the advantages that: need not dismantle from rear wheel installation axle 15 locking nut 14 and get off and can realize the dismouting to skeleton texture 11, have the efficient advantage of dismouting.

Further, as shown in fig. 3 and 4, the guide passage 13 is vertically arranged along the length direction thereof. This arrangement facilitates adjustment of the skeletal structure 11.

As an embodiment of the present embodiment, as shown in fig. 3, the guide passage 13 is located above the first through hole 12. The technical effect of the scheme is as follows: when the framework structure 11 is installed, the guide channel 13 of the framework structure 11 slides down on the rear wheel installation shaft 15 rapidly under the action of self weight, so that the framework structure 11 can be installed rapidly.

As an embodiment of the present embodiment, as shown in fig. 4, the guide passage 13 is located below the first through hole 12. When the bicycle is in use, the rear wheel mounting shaft 15 moves in the guide channel 13 under the condition that the locking nut 14 is loosened and the locking nut 14 does not fall off, so that the rear wheel can be prevented from falling off when continuously sliding downwards.

As an implementation manner of this embodiment, as shown in fig. 1 and fig. 2, the framework structure 11 is composed of a first longitudinal section 16, a transverse section 17 and a second longitudinal section 18, the transverse section 17 is located between the first longitudinal section 16 and the second longitudinal section 18, the first longitudinal section 16 is provided with a first through hole 12 and a guide channel 13, and the second longitudinal section 18 is provided with an auxiliary wheel.

Further, a diagonal brace 19 is installed between the first longitudinal section 16 and the transverse section 17, one end of the diagonal brace 19 is fastened on the first longitudinal section 16, and the other end of the diagonal brace 19 is fastened on the transverse section 17.

The technical effect of the scheme is as follows: the structural stability between the first longitudinal segment 16 and the transverse segment 17 can be effectively improved.

As an embodiment of the present embodiment, the brace 19 is a rigid member or an elastic member. When the inclined strut 19 is an elastic member, the structural specification of the elastic member 19 is not shown in the drawings, and the specification of the elastic member can be selected according to a specific use scenario.

Further, the first longitudinal section 16, the transverse section 17 and the second longitudinal section 18 are integrally formed;

or as shown in fig. 2, the first longitudinal segment 16 is hinged with the transverse segment 17, and the transverse segment 17 is fixedly connected with the second longitudinal segment 18. This scheme mainly used adaptation bracing 19 is the application scene of elastic component for carry out the shock attenuation to the auxiliary wheel, can effectively avoid taking place because of the not contactless situation of the auxiliary wheel that the road caused and ground. The proper elastic part is selected to meet the specific use requirement, wherein the elastic part can adopt a spring, and the material of the spring is the same as that of a damping spring on the bicycle.

For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
