Abstract
The utility model relates to a folding bicycle with a reinforced tube folding joint; a bicycle beam uses multiple-connection rod fast-locking joint; pin rods at the lower parts of two connection plates of the joint are respectively connected with a reinforced frame. The design avoids the problem that two connection plates at the lower part of the joint are bent by oversized stress, and improves stiffness and strength of the folding bicycle with a single tube at the position of the folding joint.
Description
The utility model relates to the folding bicycle of single-beam.
The single-beam folding bicycle has a folding joint at the middle part of beam, during cycling, this joint is stressed bigger, especially adopt a kind of bicycle of many connecting rods fast fastening joint, the involutory interlocking of its folding joint realizes with two pin rods under the tight coupling of many link lock, and this joint is stressed when excessive, and often rigidity is inadequate slightly for two pin rods under the joint, particularly jolt when being subjected to instantaneous impact very big riding, may cause pin rod crooked and influence the use of folded bicycle.
The purpose of this utility model is to provide the folding bicycle that a kind of tool is strengthened folding joint, to improve the rigidity at folding joint place.
Tool described in the utility model is strengthened the folding bicycle of folding joint, adopts many connecting rods fast fastening joint on the car beam, connects a hog frame respectively on the pin rod under two connecting panels of joint, and the other end of hog frame is connected with the back vehicle frame with Che Liang respectively; Pin rod and hog frame can adopt the rotary type connection mode, change as hinge joint, strand.
The utility model is owing to connect hog frame on the folding joint pin rod down, and hog frame and Che Liang link to each other with back vehicle frame, obviously increases the stiffness of pin rod, thereby the rigidity of whole folding joint and intensity are significantly improved.In addition, when joint was opened, stirrup bent simultaneously with two connecting panels and the car beam of joint, does not influence the folding of folding joint.
Now in conjunction with the accompanying drawings the utility model is further described:
Accompanying drawing 1 is common single-beam folding bicycle joint design scheme drawing;
Accompanying drawing 2 is common single-beam folding bicycle frame structural representations;
Accompanying drawing 3 is the utility model folding joint structural representations;
Accompanying drawing 4 is the utility model body frame structure for automotive scheme drawings.
Shown in accompanying drawing 1, accompanying drawing 2, two connecting panels that are hinged of the fast fastening joint on the car beam respectively have pin rod 5a, a 5b 5,6 times, and multi-connecting-rod mechanism 4 can be stirred pin rod 5a, 5b, and connecting panel 5,6 is opened or involutory.
Shown in accompanying drawing 3, accompanying drawing 4, two pin rod 5a, 5b bottoms connect hog frame 6a, a 6b respectively, and two hog frame 6a, the 6b other end link to each other with the car beam respectively.
Claims (2)
1, a kind of tool is strengthened the folding bicycle of folding joint, adopts many connecting rods fast fastening joint on the car beam, it is characterized in that connecting a hog frame respectively on two plates that are articulated and connected pin rod down of its joint, and the hog frame other end and Che Liang are connected with back vehicle frame.
2, strengthen the folding bicycle of folding joint by the described tool of claim 1, it is characterized in that hog frame and pin rod adopt rotary type to be connected.
