Detailed Description
As shown in figures 1-3, the technical scheme adopted by the specific embodiment is that the novel one-key telescopic length-adjustable bicycle rear handrail comprises a handle 1, a supporting tube 2, a telescopic tube 3, a first fixing plate 4 and a second fixing plate 5, wherein the supporting tube 2 is in a bent L shape, the upper end of the supporting tube 2 is welded with the handle 1, the lower end of the supporting tube 2 is provided with three spring buckle holes 6, one end of the telescopic tube 3 is provided with a spring buckle 7, the other end of the telescopic tube is welded with the first fixing plate 4, four corners of the first fixing plate 4 and the second fixing plate 5 are respectively provided with bolt holes, and the first fixing plate 4 and the second fixing plate 5 are installed on a bicycle frame through the bolt holes 8 penetrating through the bolt holes.
The surface of the handle 1 is provided with anti-skid grains 9, so that the surface friction force is increased.
The working principle of the specific embodiment is as follows: a novel one-key telescopic length-adjustable bicycle rear handrail is installed on a frame below a bicycle saddle, a second fixing plate 5 is placed at the front end of the frame, a first fixing plate 4 is placed at the rear end of the frame, a bolt 8 is inserted into a bolt hole corresponding to the second fixing plate 5 and the first fixing plate 4 to fixedly install the second fixing plate and the first fixing plate on the frame, a supporting tube 2 is inserted into a telescopic tube 3, a spring fastener 7 is pressed by hand at the same time, the supporting tube 2 is pushed to enable the spring fastener 7 to enter a spring fastener hole 6, and the spring fastener 7 rebounds to clamp the supporting tube 2, so that the rear handrail can be used after being installed; when a passenger feels that the space of the backseat of the bicycle is narrow, the spring fastener 7 is pressed down by hand, the support tube 2 is pushed towards the first fixing plate 4, the spring fastener 7 enters the spring fastener hole 6 at the tail end of the support tube 2, the spring fastener 7 rebounds to clamp the support tube 2, and at the moment, the space of the passenger is enlarged; when a user feels that the space of the backseat of the bicycle is open, the spring fastener 7 is pressed down by hand, the supporting tube 2 is stretched in the direction opposite to the first fixing plate 4, the spring fastener 7 enters the spring fastener hole 6 at the innermost end of the supporting tube 2, the spring fastener 7 rebounds to clamp the supporting tube 2, and the space of the user is reduced at the moment.
This embodiment structural design is reasonable, easy operation, and convenient to use is safer, and the person of taking can adjust the space of bicycle back seat through the position of adjusting the snak link according to the demand of self at any time.
The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
