Description

Bicycle with air-tube damping saddle

The utility model relates to a kind of improved bicycle structure, and particularly a kind of bicycle has the saddle damping device of tracheae.

Existing bicycle saddle pattern is more, and buffer action mainly is made up of seat bow stage clip and one group of extension spring.At first to guarantee the intensity and the rigidity of saddle, guarantee that the triangle point position is out of shape not quite under external force, therefore a buffer action that the bow stage clip rises is not enough, pooling feature mainly depends on one group of extension spring under the saddle, unbalance stress, extension spring damages easily, have the sense of jolting if travel on abominable road surface, and tracheae is to carry as annex.

With existing utility model patent CN87216849U " a kind of bicycle shock absorption device ", " " the bicycle saddle bumper is compared, and the utlity model has the advantage that bumper and absorbing shock and gas filled device are installed together for CN87200087U " bicycle damper ", CN87205036.In addition prevent to rotate axially directed simple in structure, manufacturability is strong, forms damping device by left-handed spring, two kinds of stage clips of dextrorotation spring, rectilinearity is good than the stage clip of single rotation direction.Compare to have with existing utility model patent CN205571U " bicycle self gas filled device " shock absorber is housed simultaneously, do not need handle and place the special saddle of groove, therefore saddle highly versatile, saddle revolves backward and turn 90 degrees inflatablely during inflation, need not mobile saddle cover.

The purpose of this utility model is to avoid above-mentioned existing weak point that the saddle that has tracheae buffering bicycle is provided.Be in the profile that does not change original bicycle, increase by a cover damping device, reduce the sense of discomfort in abominable road surface or long-distance running.And utilize standpipe on the spider as the appendix cylindrical shell, increase by a cover appendix, and combine together with damping device.

Describe in further detail below in conjunction with accompanying drawing:

Figure 1 shows that the utility model structure longitudinal sectional drawing;

Figure 2 shows that the double-screw bolt section-drawing of the utility model B portion band check valve;

Figure 3 shows that the utility model A portion piston rod head section-drawing;

The utility model is shown in Figure 1 such as reference with the damping saddle bicycle of inflator: this device comprises saddle grip block (1), clamping cover plate (2), riveted joint nail (3), be welded in the seat board (4) on the movable socket, movable socket (5), upper gear pipe (6), left-handed stage clip (7), fixing socket (8), dextrorotation stage clip (9), counter-sunk screw (10), resistance sheet (11), catch (12), leather cup (13), pad (14), gas shutoff plectane (15), nut (16), piston rod (17), the inflation flexible rubber hose (18) of Band clamp, lower block tube (19), rivet (20), clamp (21), tripod (22), rivet (23), snap close (24), rivet shaft (25), bolt, nut, packing ring (26), (27), (28), handgrip (29), general saddle (30), riveting silk (31). With reference to shown in Figure 2: steel ball (32), the double-screw bolt (33) with check valve, spring (34). By general saddle (30), by two clamping cover plates (2), be separately fixed on two saddle grip blocks (1) with bolt, nut, packing ring (26), (27), (28). Saddle grip block (1) is hinged on the both sides of the seat board (4) of movable socket with rivet (3), makes general saddle (30) after freeing snap close (24), can rotate backward. Snap close (24), during non-inflatable pipe, is buckled on the seat board (4) of movable socket on saddle grip block (1) with rivet (25) riveting. In the standpipe of bicycle tripod (22), the fixedly socket (8) of bottom riveted joint lower block pipe (19) and the movable socket (5) of the top upper gear pipe of riveted joint (6) are housed, be riveted with rivet (23), between two sockets, fill left-handed spring (7), dextrorotation spring (9), lower block tube (19), is enclosed within on the movable socket good direction on fixing socket (8) with rivet (20) riveting. Behind the hand spring, with counter-sunk screw (10), fixed barrier (11) on movable socket (5), lower block tube (19) sidewall of riveting on fixing socket (8) removes 1/3rd and outstanding 1/3rd the combining of movable socket (5), to guarantee that two sockets only move axially, prevent from rotating. Form one in movable socket (5) bottom with counter-sunk screw (10) fixed barrier (11).

And utilize the standpipe bottom as the tracheae body, the piston rod (17) of catch (12), leather cup (13), pad (14), nut (16), band steel ball (32) valve is housed. After being inserted in buffer unit, can filling handgrip (29) and also be riveted with riveting silk (31). Complete unit can be packed in the standpipe of tripod (22), securing member with existing bicycle is fastening, be loaded on the double-screw bolt (33) with check valve, double-screw bolt should be loaded onto earlier the inflation flexible rubber hose (18) of Band clamp, and will inflate on the standpipe that flexible rubber hose (18) is fixed on the tripod (22) that clamp (21) are housed, to note being coated with lubricating oil during assembling. Shown in the double-screw bolt profile of Fig. 2 B section check valve: after putting into steel ball (32) spring (34), oral area rolls mouth, prevents that steel ball from dropping out with the double-screw bolt (33) of check valve. Shown in Fig. 3 A section enlarged drawing: the head at piston rod (17) has axial unidirectional valve opening, and the aperture of air inlet and air inlet duct roll mouth and prevent that steel ball from dropping out after putting into steel ball.

The utility model changes fixedly socket and movable socket at the connecting portion of saddle and tripod standpipe, and increases spring left-handed and two one group of dextrorotation in socket, is the vibration that absorbs in the bicycle running. Utilize in addition the tripod standpipe as the tracheae body, saddle two grip blocks are hinged on the biside plate of movable socket with rivet, when inflation, make saddle after opening the snap close that grip block rivets, saddle backward more than the 90-degree rotation, expose and be enclosed in the standpipe with the handgrip on the piston rod of piston, piston rod is moved back and forth, namely inflatable. A gas shutoff plectane is welded at five-way position, tripod standpipe bottom, and the inflation flexible rubber hose is loaded on the five-way position with the Stud connection with check valve. When not inflating, the handgrip on the piston rod is placed between saddle and the seat bow naturally. The inflation flexible rubber hose is fixed with clamp, is tiltedly to stand on the standpipe of tripod. Underpart of the piston rod be connected the five-way double-screw bolt on be equipped with the steel ball check valve.

The utility model has the saddle buffering bicycle of tracheae, and the effect of travelling on long-distance or abominable road surface is more obvious, has increased cyclist's comfort.And has aerification function to Ben Che and its car.Simple in structure, manufacturability is strong.
