Description
Technical Field
The utility model belongs to the technical field of the bicycle frame, concretely relates to foldable bicycle frame.
Background
With the popularization of the shared bicycle, various bicycles appear in the market, but the bicycle is inconvenient to carry due to the volume factor of the bicycle, so that the existing folding bicycle is complex in structure and complex to assemble, and therefore a folding bicycle frame is needed to solve the problems.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a foldable bicycle frame to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a foldable bicycle frame, includes front truck frame and rear truck frame, front truck frame and rear truck frame are articulated mutually, and the tip welding of front truck frame has the connecting plate, and the top of front truck frame is seted up flutedly, and one side welding of rear truck frame has two head rods and second connecting rod, and the one end of two second connecting rods respectively with two head rod fixed connection, the round hole has been seted up to rear truck frame bottom.
Further, the end of the first connecting rod is provided with a claw mounting groove.
Furthermore, the second connecting rod and the first connecting rod are in a triangular structure.
Compared with the prior art, the beneficial effects of the utility model are that:
being the triangle-shaped structure through second connecting rod and head rod has ensured the holistic stability of frame, comparing simultaneously in the folding bicycle on the existing market, frame overall structure is simpler, and it is more convenient to assemble.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. a rear frame is turned; 2. a circular hole; 3. a front frame; 4. a circular hole; 5. a connecting plate; 6. a connecting plate; 7. a first connecting rod.
Detailed Description
The present invention will be further described with reference to the following examples.
The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention. The condition in the embodiment can be further adjusted according to concrete condition the utility model discloses a it is right under the design prerequisite the utility model discloses a simple improvement of method all belongs to the utility model discloses the scope of claiming.
Referring to fig. 1, the present invention provides a foldable bicycle frame, including a front frame 3 and a rear frame 1, the front frame 3 is hinged to the rear frame 1, a connecting plate 5 is welded to the end of the front frame 3, a groove 4 is formed at the top of the front frame 3, two first connecting rods 7 and two second connecting rods 6 are welded to one side of the rear frame 1, one ends of the two second connecting rods 6 are respectively fixedly connected to the two first connecting rods 7, and a circular hole 2 is formed at the bottom of the rear frame 1.
In the present embodiment, the end of the first connecting rod 7 is provided with a claw mounting groove.
In the present embodiment, the second connecting rod 6 and the first connecting rod 7 have a triangular structure.
When using, at first with fore-stock 3 and car after-frame 1 articulated together, then at the tip welding upper junction plate 5 of fore-stock 3, the top of fore-stock 3 is seted up flutedly 4 can alleviate the weight of frame, other auxiliary assembly can be installed simultaneously, after that one side welding of after-frame 1 goes up two head rods 7 and second connecting rod 6 again, second connecting rod 6 and head rod 7 are the triangle-shaped structure, again with the one end of two second connecting rods 6 respectively with two head rods 7 fixed connection, set up a round hole 2 in the bottom of car after-frame 1 main shaft at last can, generally, it has ensured the holistic stability of frame to be the triangle-shaped structure through second connecting rod 6 and head rod 7, compare in the folding bicycle on the existing market simultaneously, frame overall structure is simpler, it is more convenient to assemble.
In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and to simplify the description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.
