Specific embodiment

As shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6 and Fig. 7, the arc curved handle switch knob of this creation is adjustable seat pipe height is mainly wrapped Contain:

One beam ring 10 is mainly made of the clamping piece 11 of a bending, is respectively equipped with through-hole at the both ends of the beam ring 10 111, which is assembled in an arc curved handle, and an internal screw thread section 12 is equipped in the beam ring 10, which can be set to In 111 inner wall surface of through-hole.

One connecting piece 20, with a pedestal 21 and the hinge portion 22 extended by the pedestal 21, the pedestal 21 and the beam ring 10 connections, the hinge portion 22 have a connecting hole 221, which is assembled in the connecting hole 221 close to the beam ring 10 Side, the pedestal 21 are equipped with line perforation 211, and the control line 42 for providing an adjustment seat pipe 40 is penetrated and fixed.

One plectrum 30, the plectrum 30 have pass through aperture 31, which is assembled in the hinge portion through the through hole 31 22, and hinge portion 22 is penetrated with first bolt 32, and lock with the internal screw thread section 12, which has one first to stir section 33 and one second stir section 34, and the hinge portion 22 is enabled first to stir the boundary line that section 33 and the length are stirred as this so that this first It stirs section 33 and this second is stirred section 34 and rotate along the hinge portion 22, have a crimping 35 by the control line in the plectrum 30 42 from the line perforation 211 penetrate after, the control line 42 is clamped to the crimping 35 through one second bolt 36；In this wound Make in an embodiment, as shown in figure 4, wherein the internal screw thread section 12 is a forcing piece 121, which is assembled in the connection Hole 221 close to the side of the beam ring 10, can corresponding spiral shell set first bolt 32, wherein the plectrum 30 and the packing Part 121 locks.

Please continue to refer to shown in Fig. 3 to Fig. 7, the motion characteristic of this creation is: this its mainly by the clamping piece of a bending 11 are constituted, which is assembled in an arc curved handle；The connecting piece 20 is extended with a pedestal 21 and by the pedestal 21 Hinge portion 22, the pedestal 21 are connect with the beam ring 10；The plectrum 30, the plectrum 30 have pass through aperture 31, which penetrates The through hole 31 is assembled in the hinge portion 22, and with bolt locking, which produces along the hinge portion 22 of the connecting piece 20 It is raw to pivot.

It please refers to shown in Fig. 2 to Fig. 6, the mode of this creation combination, firstly, the assembling of clamping piece 11 of the beam ring 10 again should On arc curved handle, and the forcing piece 121 penetrates the through-hole 111, which is socketed on the beam ring 10 again, the plectrum 30 sets lock in hinge portion 22 through one first bolt 32, have internal screw thread section 12 in the forcing piece 121, can drive when sealed The plectrum 30 and connecting piece 20 are gradually mobile towards 10 direction of beam ring, and three parts are closely combined in arc curved handle；Then it takes Control line 42 is first penetrated 21 line of the pedestal perforation 211 of connecting piece 20, continued control line by the control line 42 of the adjustment seat pipe 40 42 pull down, and have a crimping 35 on the plectrum 30, aforementioned control line 42 is put into the crimping 35, lock through the second bolt 36 Gu on the crimping 35, so that the control line 42 is clamped in the crimping 35 of plectrum 30.

It please refers to shown in Fig. 2 to Figure 10, no matter user can be carried out the high low-key of seat pipe under any riding configuration Whole, second bolt 36 presses its crimping 35 first, and a user needs to stir section 33 towards first or stir section 34 towards second It rotates forward or backwards, since the other side of control line 42 is connected in adjustment seat pipe 40, when the variation of the length of control line 42 The pressure switch 41 of adjustment seat pipe 40 lower section can be caused to generate variation, such as when present dynasty first stirs section 33 and rotates, cause to control Line 42 releases stress switch 41, and 43 position of telescopic rod of the adjustment seat pipe 40 can decline at this time；34 turn of section is stirred by present dynasty second When, 42 squeeze pressure switch 41 of control line is caused, 43 position of telescopic rod of the adjustment seat pipe 40 can rise at this time, when user confirms Adjust the height of seat pipe 40 it is suitable when, then the second bolt 36 is screwed through hand-held tool, can be completed that adjust the adjustment seat pipe 40 high The operation of degree.

Through said mechanism, effect obtained by this creation is as described below: since existing arc curved handle adjustment seat pipe 40 is high The switch of degree is mounted in flat segments mostly, and in use less smoothly, through the structure turn of this creation, the plectrum 30 is The height that the adjustment seat pipe 40 can be adjusted at once, has the advantages that convenient, smoothly etc. multiple, overcomes the deficiencies in the prior art.
