Abstract
The utility model discloses a structure of a folding type saddle crutch. The saddle crutch comprises a crutch head and a crutch seat which are connected movably, a saddle is fixedly connected with the crutch head; a sinking elbow is arranged at the front end of the crutch head, the crutch seat is provided with a concave hole which is matched with the sinking elbow, the sinking elbow is contained in the concave hole, a straight slot is arranged on the crutch seat and is internally provided with a movable pull rod, and the front end of the pull rod extends into a sinking elbow interlocking hole so as to fix the crutch head and the crutch seat relatively. In the structure, the structure that the front end of the pull rod extends into the sinking head interlocking hole so as to relatively fix the crutch head and the crutch base is adopted, so that the contact area between the crutch head and the crutch seat is enlarged, and the safety coefficient is increased obviously, thus providing condition for a folding type electric bicycle driven by a rider.
Description
Technical field
The utility model relates to the bicycle part field, relate in particular to structure that the saddle of Electrical Bicycle turns,
Background technology
Saddle belongs to one of bicycle part, and the market consumption is very big, but conventional saddle, be traditionally arranged to be with the bicycle strut bar affixed, thereby with saddle fixation; And concerning the bicycle that requires folder function, the structure of this saddle can not satisfy the technical requirements that saddle is overturn according to actual needs.Disclose a kind of structure of saddle on the market, comprised the saddle pad that is arranged on the marshall springs, described marshall springs front end has hook, with the near front end of clasp joint the one fixing pivot point of marshall springs is set on the marshall springs.Clamp in the saddle both sides with intermediate plate at this pivot point place, and use the screw rod tingle, is set to get final product with the flexible connection of bicycle strut bar again; During practical application, perfect inadequately because of the bonded assembly interlock function of marshall springs and hook, still there is local influence in the safety when riding, and safety factor is relatively low, thereby is necessary further to improve on this basis.
The utility model content
The purpose of this utility model provides the structure that a kind of folding saddle turns.
The technical solution of the utility model is achieved in that
The structure that provides a kind of folding saddle to turn is characterized in that: described saddle turns and comprises and turn head and turn seat, turn head and flexibly connect with turning seat, saddle with turn affixed; A described front end that turns is provided with a heavy elbow, turn seat and be provided with a shrinkage pool and cooperate with described heavy elbow, described heavy elbow is contained in the shrinkage pool, turns and also is provided with a straight trough on the seat, a ccontaining active pull rod in the straight trough, pull bar front end stretch in the heavy elbow interlocking hole and will turn head and turn a relative fixed.
The structure that aforesaid folding saddle turns is characterized in that: described pull bar is made up of pull bar front end and back end of tie rod two parts, and pull bar point diameter and straight trough groove footpath are suitable; The straight trough rear end is provided with a through hole, and the diameter of described through hole and back end of tie rod diameter are suitable.
The structure that aforesaid folding saddle turns is characterized in that: bottom, described straight trough rear end is provided with a retracing spring.Be used for pull bar and keep stretching out forward, turn head when guaranteeing to ride and turn an interlocking.
The structure that aforesaid folding saddle turns is characterized in that: described back end of tie rod also is provided with a draw ring.Be used for positioning tie bar and control pull rod moves.
When the utility model uses, saddle fixation turning on the head that saddle turns, is turned head and turns the seat axle and is connected, saddle is to turning a front end when screwing off, and the pull bar front end stretches under action of the spring in the heavy elbow interlocking hole and will turn and turn a relative fixed.When needing Foldable saddle, only need the pulling draw ring, the withdrawal of pull bar front end with sink elbow interlocking hole and separate, but perk saddle then.Thereby reach the purpose of Foldable saddle.
The utility model adopts the pull bar front end to stretch in the heavy elbow interlocking hole and will turn head and turn the relatively-stationary structure of seat, has increased an area of contact that turns head and turn, and safety factor obviously improves, thereby provides condition for the people that rides drives folding electric bicycle.
