Abstract
The utility model relates to the technical field of food processing equipment, in particular to a foldable bicycle frame. The foldable bicycle frame comprises a transverse beam, wherein a frame front tube is hinged to the front end of the transverse beam; a saddle device is connected to the back end of the transverse beam; a rear fork is hinged to the upper part of the saddle device; the saddle device comprises an outer tube; an inner tube is arranged in the outer tube; a saddle main tube is connected to the upper end of the outer tube through a disassembly and assembly device; the rear fork is hinged to the upper end of the saddle main tube; a spring is arranged between the inner tube and the outer tube; a foldable buckle is arranged between the transverse beam and the frame front tube; a hung sheet which is hung in cooperation with the rear fork is arranged on the outer tube. By arranging the spring between the inner tube and the outer tube, a damping effect can be achieved. The foldable buckle is arranged between the transverse beam and the frame front tube, the hung sheet is arranged on the outer tube, and the folded frame can be prevented from being unfolded through the foldable buckle and the hung sheet.
Description
Technical field
The utility model relates to bicycle equipment technical field, particularly a kind of Foldable bicycle vehicle frame.
Background technology
At present, Foldable bicycle of the prior art, the most of crossbeam of folding stand and front pipe of vehicle frame of adopting coordinates folding, volume after folding is larger, and in addition, folding vehicle frame is inconvenient to install shock absorption device, therefore do not there is damping effect, and vehicle frame after folding easily scatters.
Utility model content
The purpose of this utility model is for the deficiencies in the prior art, provides a kind of convenient folding and volume after folding is little, can not scatter after folding, can also play the Foldable bicycle vehicle frame of damping effect.
For achieving the above object, the utility model is by the following technical solutions: a kind of Foldable bicycle vehicle frame, comprise crossbeam, crossbeam front end is managed before being hinged with vehicle frame, crossbeam rear end is connected with saddle, saddle upper articulation has back vent, described saddle comprises outer tube, in outer tube, be provided with inner tube, outer tube upper end is connected with vehicle seat supervisor by tearing locking device open, described back vent is articulated with vehicle seat supervisor's upper end, between described inner tube and outer tube, be provided with spring, before described crossbeam and vehicle frame, between pipe, be provided with folding fastener, described outer tube is provided with and coordinates the lacing film articulating with back vent.
Wherein, described crossbeam offers groove, and before vehicle frame, pipe is provided with the guide rail sliding with groove fit, and described folding fastener comprises shell, and shell is coated on outside crossbeam and the front pipe of vehicle frame, between shell and crossbeam, is provided with pulley, and before vehicle frame, pipe rear end is provided with block.
The utility model beneficial effect is: the utility model comprises crossbeam, crossbeam front end is managed before being hinged with vehicle frame, crossbeam rear end is connected with saddle, saddle upper articulation has back vent, described saddle comprises outer tube, in outer tube, be provided with inner tube, outer tube upper end is connected with vehicle seat supervisor by tearing locking device open, described back vent is articulated with vehicle seat supervisor's upper end, between described inner tube and outer tube, be provided with spring, before described crossbeam and vehicle frame, between pipe, be provided with folding fastener, described outer tube is provided with and coordinates the lacing film articulating with back vent; The utility model, by be provided with spring between inner tube and outer tube, can play the effect of damping, is provided with folding fastener before crossbeam and vehicle frame and outer tube is provided with lacing film between pipe, and folding fastener and lacing film can prevent that the vehicle frame after folding from scattering.
