The specific embodiment
See also Fig. 1 and shown in Figure 2, the seat high-low regulating that preferred embodiment of the present utility model provided can be applicable to the general seat or the seat of electric bicycle etc., includes:
One telescoping tube group (10) includes one first pipe fitting (11) and one second pipe fitting (16), wherein
The middle section position of this first pipe fitting (11) is provided with one along its holding firmware that radially outward protrudes out (12).This holding firmware (12) is that a pin radially passes this first pipe fitting (11), makes its two end be exposed to outside this first pipe fitting (11).
This second pipe fitting (16) has three groups of Height Adjustment grooves (17) (18) (19) on its tube wall, respectively this Height Adjustment groove becomes the opening shape at an end of this second pipe fitting (16).Each is organized Height Adjustment groove (17) (18) (19) and is the set deep trouth that waits on the tube wall of relative two ends radially of this second pipe fitting (16).Define the degree of depth minimum of first group of Height Adjustment groove (17) at this utility model, second group of Height Adjustment groove (18) takes second place, and the degree of depth maximum of the 3rd group of Height Adjustment groove (19).
One seat surface connector (20), central authorities have a perforation (21), and a side has an ear (22).This seat surface connector (20) is hubbed at an end of this first pipe fitting (11), can freely rotate with respect to this first pipe fitting (11).
One clamping device (30) includes a plate machine bar (31), and revolves a fastener (32) and a torque spring (33).This plate machine bar (31) has one first end (311) and one second end (312), and the two has a connecting hole.The ear that this plate machine bar (31) utilizes a pin (34) to pass this seat surface connector (20) closes (22) and this connecting hole, makes it to be articulated on this seat surface connector (20).This revolves fastener (32) is a circular block, and there is a perforation (321) in central authorities, be communicated with the axis hole of this first pipe fitting (11), and periphery have a plurality of locating slots (322).This revolve fastener (32) go up this second group of Height Adjustment groove (18) and this first group of Height Adjustment groove (17) on angle and second pipe fitting (16) between adjacent two locating slots (322) and and the 3rd group of Height Adjustment groove (19) between angle rough identical.Second end (312) when this plate machine bar (31) of downward promotion, can make first end (311) of this plate machine bar (31) fall into the wherein locating slot (322) that this revolves fastener (32), this seat surface connector (20) can't be rotated with respect to this second pipe fitting (16).As upwards spurring second end (312) of this plate machine bar (31), can make first end (311) of this plate machine bar (31) leave this locating slot that revolves fastener (32) (322), this seat surface connector (20) can be driven and be rotated with respect to this second pipe fitting (16) at this moment.This torque spring (33) makes the initial position of its first end (311) be arranged in this locating slot that revolves fastener (32) (322) in order to this plate machine bar (31) one elastic force to be provided.
One separator (40) has a post portion (41), and a dishful of (42) are positioned at an end and a perforation (43) of this post portion (41), run through this post portion (41) and this dish portion (42).This separator (40) also has a disconnection portion (44), extends to this post portion (41) by this dish portion (42), makes this post portion (41) have elasticity in radially direction.This separator (40) is inserted in this first pipe fitting (11) by this perforation (321) of revolving fastener (32) with this post portion (41), and is the state of slight interference engagement.This dish portion (42) is positioned at revolving between fastener (32) and this seat surface connector (20) of this first pipe fitting (11), and its function is to reduce the frictional force that this seat surface connector (20) is produced when rotated with respect to this first pipe fitting (11).
During combination, the bottom of this second pipe fitting (16) is fixedly arranged on the electric bicycle (not shown), or installs a runners (not shown).One seat surface (50) (as the dotted line among Fig. 2), its bottom side has a connecting rod (51).This seat surface (50) is inserted by the perforation (21) of this seat surface connector (20) with this connecting rod (51), and is fixed together with this seat surface connector (20), uses for user's seat thereon.This first pipe fitting (11) then inserts in this second pipe fitting (16), and this holding firmware (12) is contained in (Fig. 2 is located in this first group of Height Adjustment groove (17) for showing this holding firmware (12)) in a certain group of Height Adjustment groove.Install a quick detach tightening piece (13) at last in the outside of this second pipe fitting (16), in order to this first pipe fitting (11) and second pipe fitting (16) are fixed together.
See also Fig. 2, holding firmware (12) on this first pipe fitting (11) can be by the bottom of block in this first group of Height Adjustment groove (17), because this first group of Height Adjustment groove (17) is a degree of depth minimum, therefore, the high adjusting device of seat support of the present utility model this moment is positioned at the seat high state that provides the highest.
Adjust seat when high as need, see also Fig. 3, at first loosen this quick detach tightening piece (13), make this first pipe fitting (11) upwards spur, make the holding firmware (12) of this first pipe fitting (11) leave this first group of Height Adjustment groove (17).Now in turning back to this second pipe fitting (16) again, makes this holding firmware (12) be contained in this second group of Height Adjustment groove (18) (as shown in Figure 3) this first pipe fitting (11) rotation, one angle.Because the degree of depth of this first group of Height Adjustment groove (17) of depth ratio of this second group of Height Adjustment groove (18) is big, therefore, the high adjusting device of seat support of the present utility model is positioned at the high state of seat that provides lower.
After this first pipe fitting (11) is rotated, this seat surface (50) also can be rotated an angle, this moment the user can on draw second end (312) of this plate machine bar (31), make first end (311) of this plate machine bar (31) leave this locating slot that revolves fastener (32) (322).Thus, this seat surface connector (20) can rotate with respect to this first pipe fitting (11) with this seat surface (50).After the user can drive this seat surface (50) and returns back to the origin-location, decontrol this plate machine bar (31), because the effect of this torque spring (33) can make first end of this plate machine bar (31) fall into another locating slot (322 ') that this revolves fastener (32).At last, lock this quick detach tightening piece (13) again, promptly finish the state that the high adjusting device of seat support of the present utility model is adjusted to time high position as shown in Figure 4.
In like manner, if the holding firmware (12) of this first pipe fitting (11) is adjusted in the 3rd group of Height Adjustment groove (19), then can provide minimum seat high state.
Last following 2 is that the applicant must propose explanation:
1, the quantity of these Height Adjustment grooves is not defined as three groups as shown in the figure, and its quantity can be the producer and selects, so that the Height Adjustment of different phase to be provided.
2, Height Adjustment groove on this telescoping tube group and the commutative setting of holding firmware, as shown in Figure 5, this holding firmware (12 ') is located on this second pipe fitting (16), and these Height Adjustment grooves (17 ') (18 ') (19 ') are arranged at first pipe fitting (11).
