Abstract
The utility model relates to a bicycle folder, which is used for bicycle folding handlebar and a folding vertical bar, wherein the folder comprises a first cam lever (1), a second cam lever (2), a lock sleeve (3) and a pin (4), the longitudinal section of the first cam lever (1) is in an eccentric outer cam shape, a connecting end of the first cam lever (1) is provided with a connecting slot (11), the longitudinal section of the second cam lever (2) also is in an eccentric outer cam shape, the connecting end of the second cam lever (2) is provided with a connecting block (21), the connecting block (21) is inserted in the connecting slot (11) and is articulated with the connecting slot (11) through the pin (4), the inner wall of the lock sleeve (3) is in an eccentric inner cam shape, and the lock sleeve (3) is sleeved on a connecting position of the first cam lever (1) and the second cam lever (2). The bicycle folder has beautiful appearance and convenient operation.
Description
(1) technical field
The utility model relates to a kind of bicycle folder, is used for bicycle folding handlebar and folding vertical rod.
(2) background technology
At present; in the bicycle application; handlebar and vertical rod are adopted folding mode through regular meeting; and conventional folding mode adopts mechanisms such as inserting the quickening folding more; this type of mode will expect that in use desirable folding locking effect just need carry out loaded down with trivial details operation; take time and effort, and appearance is provided with device such as buckle and influences integral aesthetic property.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of overall appearance and easy to operate bicycle folder are provided.
The purpose of this utility model is achieved in that a kind of bicycle folder, includes first cam lever, second cam lever, lock sleeve and pin, and the described first cam lever elevation profile is eccentric evagination colyliform, and the coupling end of first cam lever has a link slot; The described second cam lever elevation profile is similarly eccentric evagination colyliform, the coupling end of described second cam lever is provided with a contiguous block, this contiguous block is inserted in above-mentioned link slot and by pin and is hinged, and described first cam lever and second cam lever become an eccentric external cam bar integral body by being articulated and connected of pin, described lock sleeve inwall is eccentric convex colyliform, and described lock sleeve is placed on the junction of first cam lever and second cam lever.
The beneficial effects of the utility model are:
(1) adopt the cooperation of eccentric cam ring and eccentric external cam to realize locking, only with hand is rotated operation and can realizes locking easily and unclamp, do not need to use any instrument, and rotation can reach good locking effect slightly, compare more with traditional fast folding mechanism and to save time, practical convenient.
(2) articulated manner by contiguous block and link slot folds, and it is attractive in appearance more to seem when conveniently folding.

(5) specific embodiment
Referring to Fig. 1 and Fig. 2, the utility model relates to a kind of bicycle folder, include first cam lever 1, second cam lever 2, lock sleeve 3 and pin 4, described first cam lever 1 elevation profile is eccentric evagination colyliform, and the coupling end of first cam lever 1 has a link slot 11; Described second cam lever 2 elevation profiles are similarly eccentric evagination colyliform, the coupling end of described second cam lever 2 is provided with a contiguous block 21, this contiguous block 21 is inserted in above-mentioned link slot 11 and by pin 4 and is hinged, and described first cam lever 1 and second cam lever 2 become an eccentric external cam bar integral body by being articulated and connected of pin 4, as shown in Figure 3; Described lock sleeve 3 inwalls are eccentric convex colyliform, and described lock sleeve 3 is placed on the hinged place of first cam lever 1 and second cam lever 2.
Referring to Fig. 4, during use, with the junction of lock sleeve 3 covers as for first cam lever 1 and second cam lever 2, hold lock sleeve 3 and second cam lever 2 is done contrarotation, make the eccentric external cam of the eccentric cam ring of lock sleeve 3 and second cam lever 2 from certain interval being arranged up to being close to locking, reach locking effect, shown in Fig. 6～8; When needs are folding, only need hold first cam lever 1 or second cam lever 2 rotates to initial condition relatively with respect to lock sleeve 3, with lock sleeve 3 junction of sliding, utilize the hinged of pin to fold very easily subsequently, as shown in Figure 5.
