Detailed description of the invention
Refer to Fig. 1 and Fig. 2, seat of the present utility model pipe assembly 10 includes a pipe 20, bar 30, one and adjusts valve 40, and a control assembly 50.
The top of seat bar 30 is for installing a seat cushion (not shown), and the bottom of seat bar 30 is inserted in seat pipe 20 from the top of seat pipe 20, and can manage along seat 20 axial upper and lower displacement.
Adjust valve 40 and there is a valve seat 42 and a valve rod 44.Valve seat 42 is fixed in a bar 30 and can synchronize with seat bar 30 start, and valve rod 44 is located in seat pipe 20, and the top of valve rod 44 can axially movably be arranged in valve seat 42, and the bottom 442 of valve rod 44 is through a valve rod permanent seat 46 and extend to seat and manage a bottom of 20.Thus, the bottom 442 of valve rod 44 can be subject to the ejection of external force and switch the oil circuit state in valve seat 42.
As shown in Figures 2 and 3, control assembly 50 has a mount pad 51, a frizzen 52, a drive spindle 53, an auxiliary push-rod 54, a cable 55, and a master cock 56.Mount pad 51 is arranged in the bottom of seat pipe 20; Frizzen 52 is positioned at mount pad 51 and has longitudinally section 522 and a traversing section 524, and traversing section 524 goes out from the top horizontal-extending of longitudinal section 522 and the bottom 442 of butt valve rod 44; The central authorities of drive spindle 53 are by one first axle part 57 pivot joint mount pads 51, and one end of drive spindle 53 is by longitudinal section 522 of another the first axle part 57 pivot joint frizzens 52, and the other end of drive spindle 53 connects one end of cable 55; Auxiliary push-rod 54 is between the traversing section 524 and drive spindle 53 of frizzen 52, and, one end of auxiliary push-rod 54 is by one second axle part 58 pivot joint mount pads 51, the other end of auxiliary push-rod 54 is positioned at the top of the first axle part 57 and is parallel to each other with the first axle part 57 by longitudinal section of 522, the second axle parts 58 of another the second axle part 58 pivot joint frizzens 52; Master cock 56 has a clasp 562 and leader 564, clasp 562 is removably buckled in vehicle frame, wherein taking driver 12 as best position, handle 564 is hubbed at clasp 562 and connects the other end of cable 55, uses for rider and operates to pull cable 55.
In the time will adjusting the height of seat cushion, first down squeeze grip 564 is bestowed pulling force to cable 55, then cable 55 meeting pulled down drive spindles 53, as shown in Figures 3 and 4, make drive spindle 53 produce pivotable and up promote frizzen 52 with its one end, in the process up being promoted at frizzen 52, auxiliary push-rod 54 can produce along with moving on frizzen 52 pivotable, and up promote frizzen 52 with its one end simultaneously, thus, the bottom 442 that frizzen 52 can up promote valve rod 44 by the traversing section 524 of itself under the double reaction plus of drive spindle 53 and auxiliary push-rod 54, make valve rod 44 produce linear displacement and force the oil circuit in valve seat 42 to present opening state, rider now can further adjust according to demand own the height of seat cushion through the linear displacement of the relative seat pipe 20 of seat bar 30, until after seat cushion is adjusted to suitable height, as long as rider is release handle 564, make cable 55 remove the pulling force to drive spindle 53, now be arranged at the elasticity recovery part (not shown) meeting depress ovable valve stem 44 in valve seat 42 and force the oil circuit in valve seat 42 to present closed condition, to complete the location of a bar 30.
In sum, the design that seat of the present utility model pipe assembly 10 sees through auxiliary push-rod 54 can be eliminated frizzen 52 suffered side force in moving process, to promote the start smooth degree of frizzen 52, and reaches the object of rapid operation simultaneously.
