Abstract

The utility model discloses a changeable height saddle for a cycle. The changeable height saddle for a cycle comprises a saddle elevating mechanism arranged at the lower part of the saddle, and a control component arranged on the handle of the cycle. When the control component is operated by a hand, the saddle can be transformed to a height which is required following the elevating mechanism. The elevating mechanism is composed of a spring seat 1, an elevating spring 2, an elevating shaft 3, a fixed seat 4, a positioning piece 5, a connecting sleeve 6 and a guiding ring 7. The control component is composed of a moving piece 20, a fixed clip seat 21, a sleeve pipe 16 and a steel wire flexible cord 11. The lower part of the elevating shaft 3 is provided with a concave-convex structure stage by stage. The appropriate height of the saddle can be conveniently transformed by using the utility model.

Description

Bicycle saddle height converting means

The utility model relates to a kind of member of trackless terrestrial vehicle.Particularly a kind of bicycle saddle height converting means.

Existing bicycle saddle is all fixed.As everyone knows, laborsaving, the tireless advantage of bipod that suitable dais stool has, but the parking moment both feet of stopping can not surely be stepped on ground, poor stability; Though low seat stool is safer, can not stretch fatiguability and effort when both feet step; In addition, same car used by the bigger people of height differences, often need readjust a stool height, and be very inconvenient.

The purpose of this utility model is that the shortcoming at said fixing seat stool is overcome and makes a stool select laborsaving, safe altitude for use according to riving condition.

The purpose of this utility model realizes by a kind of stool height converting means.Be provided with the lifting mechanism that can make the rapid lifting locking of a stool under its present stool and on handle pipe, installed the parts of control seat stool lifting.Lifting mechanism is made up of spring abutment 1, lifting spring 2, lifting shaft 3, permanent seat 4, locations 5, adapter sleeve 6, guide ring 7, the bottom in vehicle frame pipe 18 is put in the spring abutment weldering, pack into successively on it lifting spring 2, lifting shaft 3, the bottom of lifting shaft is the convex-concave structure 27 of one-level level; Permanent seat 4 welderings are put at the vehicle frame mouth of pipe, and locations 5 lies on the permanent seat 4, and adapter sleeve 6 is fixed with permanent seat 4, locations 5 covers, the spring hole 19 extension spring clasp joint on locations and the adapter sleeve, and guide ring 7 is packed in the adapter sleeve 6.Function unit is by movable part 20, fixedly holder 21, sleeve pipe 16, steel wire flexible cord 11 are formed, and 20,21 usefulness rivets 9 are riveted and become to rotate one flexibly, and steel wire flexible cord 11 is through in the sleeve pipe 16.

Fig. 2, Fig. 3 also are embodiment of the present utility model.Below in conjunction with accompanying drawing structure of the present utility model and principle of work are further specified.Seat stool 26 is installed in 24 places of lifting shaft 3.Function unit is fixed on the driver relative with bicycle bell on 28 by mounting screw hole 14.One of sleeve pipe 16 is contained in fixedly on the holder 21.The casing seat 8 on the vehicle frame pipe 18 is inserted in the other end; Flexible cord head 13 penetrates in the flexible cord hole 17 of lifting mechanism locations 5, uses nut locking after stretching.When hand is stirred movable part 20 on handgrip 28.Locations 5 is subjected to the pulling force of flexible cord 11 to shift out convex-concave structure 27, so lifting spring 2 makes lifting shaft 3 do to rise or fall mobile with buttocks; When hand behind movable part 20.Under the extension spring effect, locations 5 and function unit reset.Locations moves in the new one-level convex-concave again.Lifting shaft is locked on the height that needs.

The utility model has the advantages that can be according to the condition of cyclery bus or train route face, rapid any conversion seat stool height in travelling. As have a lot of social connections, the people is rare, when heavy burden, upward slope or long-distance travel, can select laborsaving height; Select lower safe altitude during the many or slipperiness on roads of, people narrow when the road; The people of different heights need not when using a car instrument adjustment just arbitrarily conversion seat stool arrive suitable height.
