Abstract
The utility model relates to an improved rise and fall shock absorber for the saddles of bicycles, which is composed of a metal tube, an inner tube, a sliding cylinder whose interior is provided with an I-shaped slide block, etc. A spring is arranged between the slide block and the sliding cylinder, and the slide block is provided with a pull rope which is used for leading out the inner tube upwards and a steel ball which is used for controlling the height of a saddle carried by the inner tube. When the height of the saddle needs changing, the pull rope is lifted to drive the slide block to move upwards, the steel ball falls into the concave surface of the slide block to enable the inner tube to be out of control to slide downwards or upwards to enable the saddle to descend or rise. When the pull rope is loosened, the steel ball enters a bowl slot corresponding to the convex surface of the slide block, and the inner tube and the saddle are restored to be under control. The utility model has the advantage of simple and convenient operation.
Description
The utility model is a kind of improved saddle lifting bumper.
Known bicycle shock absorption device is to insert the metal tube by the plug screw back cover on the saddle base, between the support tube of plug screw and saddle spring is set, the vibrations that utilize the elastic buffer bicycle of spring to jolt and cause to the end user, but because the damping cushion still do not have apparatus for automatically lifting, during emergency brake common people especially women and children simultaneously both feet land and emit the danger of falling down is arranged.
The purpose of this utility model provides a kind of saddle lifting bumper easy and simple to handle.
The utility model saddle lifting bumper is to realize like this, as shown in drawings, it includes metal tube 1, metal tube 1 lower end is used for the plug screw 2 of back cover, interior pipe 14, spring 5 between interior pipe 14 and the plug screw 2, a slide cartridge 10 is housed in interior pipe 14, spring 6 is set and by the pull bar 4 of nut 1 adjustable range between slide cartridge 10 and the plug screw 2, there is an axial section to be the slide block 8 of " worker " font in the slide cartridge 10, fix a stay cord 13 on the slide block 8, stay cord 13 upper ends are passed slide cartridge 10 and are drawn outside the interior pipe 14, slide cartridge 10 barrels of corresponding slide block 8 top overhangs are provided with steel ball 9, interior pipe 14 corresponding steel ball places vertically are provided with bowl grooves 12 some and steel ball size coupling along axis direction, in addition, be provided with the axially directed grooves 15 that prevent that interior pipe 14 from rotating in metal tube 3 between interior pipe 14 and the metal tube 3.When the saddle lifting bumper of this structure uses that interior pipe 14 upper ends and cushion 16 are affixed, metal tube 3 is inserted in the saddle base, stay cord 13 is fixed on the handlebar, when needs reduce the cushion height, last rope 13 promptly drives on the slide block 8 sliding, the bowl groove 12 of pipe 10 fell into " worker " font slide block 8 concave surfaces in steel ball 9 left, in pipe 14 under the action of gravity of user's health, glide automatically after losing the control of steel ball 9, when sliding to desired height under it, loosen stay cord rapidly, slide block 8 resets under the elastic force effect of spring 11, manage in other bowls groove 12 of former bowl groove 12 vertical tops on 14 inwalls in simultaneously steel ball 9 being clamp-oned by the convex surface of " worker " font slide block, the controls that interior pipe 14 recovers steel balls 9, the cushion location.Desire returns to former height with cushion, then can bring up again stay cord 13, when falling into slide block 8 concave surfaces, steel ball 9 promotes cushion, since in this moment pipe 14 lose the control of steel ball 9 and in can twitching pipe 14 make it to rise to steel ball 9 and get back in the former bowl groove 12, loosen stay cord, cushion promptly returns to original height, operates very easy.
Description of drawings:
Accompanying drawing is the structural representation of a specific embodiment of the utility model saddle lifting bumper, 1-nut wherein, 2-plug screw, the 3-metal tube, 4-pull bar, 5-spring, the 6-spring, 7-screw, 8-slide block, the 9-steel ball, 10-slide cartridge, 11-spring, 12-bowl groove, pipe in the 13-stay cord, 14-, the 15-guide groove, the 16-cushion.
Shown in the accompanying drawing in the present embodiment, interior pipe 14, slide cartridge 10, slide block 8 are all made with the metal tube 3 consistent metallic materials of drawing materials, its warp-wise size matches each other, spring 5,6,11 all adopts the good wire spring of elasticity, stay cord 13 is a steel rope, described bowl groove 12 is three places, manages on the axial vertical line of 14 inwall correspondence " worker " font slide blocks 8 in being arranged at interval successively.For guarantee slide cartridge 10 slide under unlikely break away from pipe 14, the tube wall inboard is provided with the screw 7 that stops slide cartridge 10 to glide and play certain safety effect below the slide cartridge 10 of interior pipe 14.
Claims (2)
