Description

A kind of lifting device of bicycle seat

Technical field

The utility model relates to a kind of lifting device of bicycle seat.

Background technology

Bicycle saddle height regulates and adopts screw and nut to unscrew, the mode screwed again after regulating height, this mode regulates saddle height to need special tool, regulate cumbersome, inconvenient, and if nut does not screw, can because the pressure of body weight can allow seatpillar slide down time by bike.Also has a kind of lifting device of bicycle seat now; the basis of former screw and nut adds a seatpillar quick detach; its principle is an eccentric spanner; only need pull seatpillar quick detach and adjustable seatpillar degree of tightness; regulate saddle height; although this device is convenient; but pull pine and compress the larger strength of seatpillar quick detach needs; woman and child use also more difficult; the situation that when firmly not pulling or there will be by bike, seatpillar slides down, firmly pulls seatpillar Quick release and often there will be pole by the situation of switch out.

Utility model content

Object to be solved in the utility model is to provide a kind of device of simple and convenient adjustment bicycle saddle height, and uses easily laborsaving, regulates rear cradling pipe to skid.

In order to achieve the above object, lifting device of bicycle seat of the present utility model is design like this: a kind of lifting device of bicycle seat, comprises cushion block, tongue, pipe link, handle, frame tube, seatpillar, saddle; Described cushion block is fixed in frame tube, shape upper-thin-lower-thick; Described tongue is above cushion block, and position can be up and down, and shape is upper thick and lower thin, and cushion block is corresponding, described tongue is connected with pipe link and handle; Described tongue falls rear and cushion block, seatpillar close contact, up mentions handle, tongue and seatpillar, will unclamp, up mention saddle between cushion block, seatpillar and tongue, also can unclamp between cushion block.

Use a kind of lifting device of bicycle seat of the present utility model to have following beneficial effect: to regulate and simple easily up mention handle or mention saddle, saddle height just can free adjustment; Heighten saddle and only need mention the position that saddle lifts needs, turn down the handle of mentioning again on tongue after saddle only need mention saddle and put down saddle again to correct position; Because Action of Gravity Field automatic impaction after saddle puts down, the weight on saddle is larger, pressure tighter, more there will not be the phenomenon that seatpillar skids.

Fig. 1 is the structural representation of a kind of lifting device of bicycle seat of the utility model.

Reference numeral: 1: cushion block, 2: tongue, 3: pipe link, 4: handle, 5: frame tube, 6: seatpillar, 7: saddle.

Detailed description of the invention

A kind of lifting device of bicycle seat, comprising: cushion block (1), tongue (2), pipe link (3), handle (4), frame tube (5), seatpillar (6), saddle (7) form; Cushion block (1) is fixed in frame tube (5), shape upper-thin-lower-thick, seatpillar (6) inserts in frame tube (5), the tongue (2) that one piece movable is had in cushion block (1) top, shape is upper thick and lower thin, just contrary with cushion block (1), tongue (2) is connected with pipe link (3) and handle (4), tongue (2) falls and can compress cushion block (1) and seatpillar (6); Mention saddle (7), cushion block (1), tongue (2) and seatpillar (6) will unclamp, and saddle (7) height just can free adjustment.Need directly to mention saddle (7) and put down to the position of needs when raising saddle (7), because Action of Gravity Field, tongue (2) understands and cushion block (1), understand automatic impaction between seatpillar (6); When needing to reduce saddle (7), first mention saddle (7) allow cushion block (1), unclamp between tongue (2) and seatpillar (6), mention handle (4) again and can turn down saddle (7), saddle (7) is lowered into correct position and puts down handle (4) again, because Action of Gravity Field, tongue (2) and cushion block (1), can understand automatic impaction between seatpillar (6); Structure of the present utility model, the weight on saddle (7) is larger, the phenomenon that more there will not be seatpillar (6) to skid, and effectively solves the situation that seatpillar (6) skids.
