Abstract
The utility model discloses a folding bicycle frame performing self-locking by using the gravity of a human body, and belongs to the technical field of bicycle frames. The folding bicycle frame comprises a front main beam for mounting a front bicycle fork and a rear main beam for mounting a rear bicycle wheel, and is characterized in that a first straight rod perpendicular to the ground is fixedly arranged at the rear end of the front main beam; a second straight rod perpendicular to the ground is fixedly arranged at the front end of the rear main beam; a rotatable bicycle seat cushion rack is mounted at the upper end of the first straight rod; a self-locking hole capable of allowing the upper end of the second straight rod to be movably inserted is formed at the bottom of the bicycle seat cushion rack; and a rotation structure allowing the second straight rod to rotate around the first straight rod is arranged at the lower ends of the first straight rod and the second straight rod. By using the gravity of the human body, the folding bicycle frame can perform self-locking after unfolded, so that a folding bicycle manufactured by the folding bicycle frame is safe and reliable to ride, simple in structure and small in size after folded, and folding operation and unfolding operation are convenient.
Description
Technical field
The utility model belongs to the cycle frame technical field, is specifically related to a kind of Folding Bicycle vehicle frame that utilizes the human body gravity self-locking.
Background technology
For bicycle can be ridden, can be convenient for carrying again, and reduce parking space, people have proposed technical scheme such as the notification number of many Folding Bicycle vehicle frames: CN101412422, " folding frame of bicycle "; Notification number: CN 201395210, " vehicle frame of folding bicycle " etc.But the technical scheme of folding frame of bicycle of the prior art all has different disadvantages, technical scheme as above-mentioned notification number: CN101412422 " folding frame of bicycle ", its complex structure, operation is loaded down with trivial details in the use, and self-locking structure only inserts the locking sleeve by clamp handle with connecting arm, this structure one when clamp handle because bicycle weares and teares tenure of use, be easy to cause the clamp handle slippage, thereby make connecting arm and the two disengagement of locking sleeve, cause safety misadventure.The technical scheme of notification number: CN 201395210 " vehicle frame of folding bicycle " and for example, it has only preceding girder pipe and back girder pipe to adopt the description that is articulated and connected of articulated section.So it is safe and reliable to provide a kind of expansion to ride, folding and expanding is easy to operate, and is simple in structure, and the technical scheme of the Folding Bicycle vehicle frame that volume after folding is little is still very necessary.
Summary of the invention
The purpose of this utility model is that a kind of Folding Bicycle vehicle frame that utilizes the human body gravity self-locking will be provided, it utilizes the human body gravitation energy that the Folding Bicycle vehicle frame is launched the back and produces self-locking, so make Folding Bicycle with it, ride safe and reliable, additional folding is launched easy to operate, simple in structure, volume after folding is little.
Above-mentioned goal of the invention is achieved through the following technical solutions, a kind of Folding Bicycle vehicle frame that utilizes the human body gravity self-locking, it comprises the back girder of the preceding girder installation bicycle rear that bicycle front fork is installed, main beam rear end was fixed with first straight-bar perpendicular to the ground before its main points were, back girder front end is fixed with second straight-bar perpendicular to the ground, a rotating bike saddle poppet is installed in the upper end of first straight-bar, and bike saddle poppet bottom is provided with one can activity insert the self-locking hole of second straight-bar upper end; The first straight-bar lower end and the second straight-bar lower end are provided with second straight-bar around the rotational structure of first straight-bar rotation; When the self-locking hole of bike saddle poppet bottom inserted second straight-bar upper end, preceding main beam rear end and the mutual pressurized of back girder front end were to top contact.
The above-mentioned Folding Bicycle vehicle frame that utilizes the human body gravity self-locking, one of its structure is that to be provided with second straight-bar be to fix one first rotating shaft in the first straight-bar lower end around the rotational structure of first straight-bar rotation described first straight-bar lower end and the second straight-bar lower end, and a pivot arm around first rotating shaft rotation is fixed in the second straight-bar lower end.
The above-mentioned Folding Bicycle vehicle frame that utilizes the human body gravity self-locking, one of its structure is that a rotating bike saddle poppet is installed in the upper end of described first straight-bar, be to fix one second rotating shaft in the upper end of first straight-bar, the bike saddle poppet is provided with the axis hole that is contained in second rotating shaft.
The utility model is because a rotating bike saddle poppet is installed in the upper end of first straight-bar, bike saddle poppet bottom is provided with one can activity insert the self-locking hole of second straight-bar upper end, so make bicycle with it, then people are sitting on the bicycle saddle cushion, people's gravity can be inserted the self-locking hole of bike saddle poppet bottom securely and be pressed in second straight-bar upper end, thereby makes the exhibition of preceding girder and back girder be connected to form self-locking; So it is safe and reliable that it is ridden.As it is folding, only need and to turn on the bicycle saddle cushion, the bike saddle poppet rotates around the upper end of first straight-bar thereupon, thereby lose the member of connection before making between girder and the back girder, can make the second straight-bar pivot arm around the rotating shaft rotation of the first straight-bar lower end, thereby make the back girder that trailing wheel is installed rotate gathering in the lump, girder closes up with the back girder before finally making; And for the bicycle made from it, then front-wheel, trailing wheel close up.Therefore its folding and expanding is easy to operate.Also have it simple in structure; Volume after folding is little, and it is little to deposit required space.
