The structural ratchet pawl angle adjustment mechanism that still sets up of above -mentioned closed ring shape for the rotation and the angle modulation of control rotation axis. The utility model provides a pair of convertible seat pad location's bicycle frame, the pad location that can sit opposite when needs carry out the hand regulation, and the messenger rides passerby and can freely vary the posture of riding, alleviates the fatigue that long -time same posture was ridden and is brought.

Description

The cycle frame of a kind of convertible cushion position

Technical field

The utility model relates to the cycle frame of a kind of convertible cushion position, belongs to attachments of a bicycle technical field.

Background technology

Along with social development, the travel mode of pleasure trip on foot is more and more subject to vast tourism fan's favor by bike, but, keep same posture to ride for a long time and be easy to make bicyclist to feel to have a pain in the back. In order to realize the transformation of riding posture, in prior art, existing relevant utility model patent has been introduced the angle regulator of bicycle handle bar, but seldom there is the correlation technique of cushion position adjustments, and existing saddle also can only regulate height, on front and rear angles, not having good mechanism can regulate.

Utility model content

The utility model provides a kind of bicycle frame, can carry out free adjustment to cushion position, meets the riding posture that bicyclist is different.

The utility model part has used a kind of click angle adjusting mechanism in prior art, the utility model patent description that Granted publication number is CN203041376U discloses a kind of device for regulating chair angle, and the utility model is local adopts angular adjustment that technique is rotated axle and locked.

The technical solution of the utility model is as follows:

The cycle frame of a kind of convertible cushion position, described vehicle frame comprises front thick stick, vehicle frame back vent, cushion, cushion bracket and closed annular structure, described cushion is arranged in cushion bracket, the afterbody of described front thick stick connects the front end of closed annular structure, the front portion of the vehicle frame back vent described in two connects the rear end of closed annular structure, described closed annular inside configuration is hollow, and a rotating shaft is laterally installed, and the Fixture for tube of seat inserting for cushion bracket is installed is installed on described rotating shaft.

In above-mentioned closed annular structure, click angle adjusting mechanism is also set, for controlling rotation and the angular adjustment of rotating shaft.

The beneficial effect that the utility model reaches: the cycle frame of a kind of convertible cushion position that the utility model provides, can manually adjust cushion position when needed, make bicyclist can freely convert riding posture, alleviate the long-time same posture fatigue of bringing of riding.
