Description
Technical field
The utility model relates to a kind of front fork, particularly relate to a kind of sturdy and durable, safe and reliable, the shock-absorbing front fork of appearance looks elegant.
Background technology
As everyone knows, the as easy as rolling off a log weakness fracture of fork hook on the front fork of battery-driven car and bicycle and breeches pipe solder together at present at plug, in addition, the shoulder box adopts steel casting to occur sand holes easily, fracture also appears in pore easily, in a single day fractureing appears in above-mentioned two parts, fatal accident will occur, to the life security generation threat greatly of the person.
Summary of the invention
Main purpose of the present utility model is to overcome above deficiency and provides a kind of sturdy and durable, and is safe and reliable, the shock-absorbing front fork of appearance looks elegant.
The technical scheme that its technical matters that solves the utility model adopts is: it comprises upper branch pipe, following breeches pipe, fork hook and shoulder box, it is characterized in that: the lower end of following breeches pipe is opening-like, be welded with circular nut in the following breeches pipe, screwed stock revolved circular nut and stretched out the open end of the lower end of breeches pipe down, then, put into spring and withstand stock, one end of upper branch pipe inserts in the following breeches pipe, the other end is screwed into the plug of hexagonal in the band, fork hook is plugged on down the open end of the lower end of breeches pipe, fork hook and following breeches pipe flush fit, have centre hole on the fork hook, and will descend the screwed stock locking of stretching out in the breeches pipe with nut, also have on the fork hook and the front wheel spindle bonded assembly collar and brake navigation button; Two upper branch pipes fuse with the shoulder box, and the place, hole at shoulder box two ends has gap and uses the bolt locking of band hexagonal socket nut, and interstitial hole and vertical tube of front fork on the shoulder box are fixed, and all are surrounded by metal inside and outside the shoulder box.
The utility model can also adopt following technical measures:
Described shoulder box adopts steel stamping part.
The metal that is surrounded by inside and outside the described shoulder box is aluminum or aluminum alloy or magnesium alloy.
Advantage and the good effect that the utlity model has are: sturdy and durable, safe and reliable, because of all being surrounded by metal so appearance looks elegant inside and outside fork hook and the shoulder box, applied range, can be widely used in the battery-driven car of oil pressure and imitative oil pressure and the shock-absorbing front fork on the electro-tricycle, also can be used on bicycle, the three-wheel vehicle.
