Front shelf
Technical field
The present invention relates to the structural development of fixing front goods basket on the bicycle, particularly a kind of the loading and unloading simply do not damaged again bicycle pipe part and born the large front shelf of goods basket weight.
Background technology
The bicycle fixing mode of goods basket of going forward has a lot, a kind of front goods basket bottom is supported on the front-wheel hub main shaft by two steel wires, and wearing the side supports sheet that is fixed on the standpipe of front fork, front goods basket sidepiece and an end fix, because bearing steel wires is stressed limited, steel wire distortion after long-term the use, the goods basket can't use, if dismantle this goods basket, the side supports sheet is exposed to the external world, and is very not attractive in appearance; Goods basket bottom is fixed in end welding or is worn the bottom support sheet that is fixed in this standpipe of front fork before another kind of, and front goods basket sidepiece is directly fixed on this standpipe of front fork by screw, this goods basket fixed form, although improved support goods basket holding capacity, but if dismounting goods basket (if not needing), can expose the screw that bottom support sheet and this standpipe of front fork stay, affect attractive in appearance; Also the erection part of the front shelf of a kind of front goods basket by being L-type is fixed in standpipe of front fork, utilize and be somebody's turn to do fixedly goods basket of front shelf horizontal part, and support the whole weight of goods basket, but the goods basket is overweight, time has been grown, and bending part easily ruptures between the erection part of these front shelf and the horizontal part.
Summary of the invention
In order to remedy above deficiency, the invention provides a kind of front shelf, easy for installation, and can bear the goods basket of enough weight, dismounting is also convenient, and does not affect the attractive in appearance of standpipe of front fork after the dismounting.
Technical scheme of the present invention is such realization: a kind of front shelf, be installed on standpipe of front fork, integrally formed by side stand and lower supporter, this side stand upper and lower part is tightly fixed on this standpipe of front fork by first, second bundle sub-folder respectively, this lower supporter below is provided with at least one reinforced rib, this reinforced rib one end is fixed in this lower supporter bottom and the other end is fixed in this side stand bottom, and is tightly fixed on this standpipe of front fork by this second bundle sub-folder in the middle of this reinforced rib.
As a further improvement on the present invention, this first bundle is comprised of upper bundle stroma and the upper stay that the middle part has respectively corresponding recess, and bundle stroma is fixed in this side stand on this, and stay two ends are fixed in bundle stroma correspondence section on this by screw threads respectively on this.
As a further improvement on the present invention, this second bundle is comprised of lower bundle stroma and the lower stay that the middle part has respectively corresponding recess, and this time bundle stroma is fixed in the middle of this reinforced rib, and this time stay two ends are fixed in this time bundle stroma correspondence section by screw threads respectively.
As a further improvement on the present invention, this lower supporter below is provided with two reinforced ribs side by side, and this two reinforced ribs, one end is individually fixed in this lower supporter bottom and the other end is individually fixed in this side stand bottom, and this time restrainted the stroma both sides and be individually fixed in the middle of this two reinforced rib.
As a further improvement on the present invention, this side stand is provided with two stationary pipes side by side along this standpipe of front fork installation direction, and bundle stroma both sides are individually fixed in this two stationary pipes on this.
As a further improvement on the present invention, these two reinforced ribs two ends are welded in respectively this lower supporter bottom and this side stand bottom, and this time bundle stroma both sides are welded in respectively this two reinforced ribs middle part.
As a further improvement on the present invention, bundle stroma both sides are welded in respectively this two stationary pipes on this.
As a further improvement on the present invention, bundle stroma is welded in this side stand on this, and the recess of restrainting stroma and upper stay this on is respectively equipped with the rubber sheet gasket of this standpipe of front fork of being convenient to be fixedly clamped.
As a further improvement on the present invention, the recess of this time bundle stroma and lower stay is respectively equipped with the rubber sheet gasket of this standpipe of front fork of being convenient to be fixedly clamped.
As a further improvement on the present invention, this side stand also is provided with for the fixing fixed orifice of goods basket sidepiece, and this lower supporter is provided with for the fixing slotted hole of goods basket bottom.
Useful technique effect of the present invention: be fixedly clamped in this standpipe of front fork by side stand by being fixed in standpipe of front fork in the middle of the reinforced rib that is provided with between the bottom with the bottom of this side stand and this lower supporter, only comparing, greatly strengthened the holding capacity of lower supporter.
Sub bundle stroma and the stay that all has a recess by the middle part of described the first bundle and the second bundle forms, further this upper and lower bundle stroma and the recess of corresponding stay are respectively equipped with the rubber sheet gasket of this standpipe of front fork of being convenient to be fixedly clamped, behind the front shelf of dismounting, standpipe of front fork is excellent like this.

The specific embodiment
In conjunction with Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, below be further described:
A kind of front shelf, be installed on standpipe of front fork 100, integrally formed by side stand 1 and lower supporter 2, on this side stand 1, the bottom is respectively by first, the second bundle 31,32 are fixedly clamped in this standpipe of front fork 100, this side stand 1 is provided with two stationary pipes 11 side by side along this standpipe of front fork installation direction, 12, these lower supporter 2 belows are provided with two reinforced ribs side by side, this two reinforced ribs, one end is welded in respectively these lower supporter 2 bottoms (can be positioned at bottom centre) and the other end is welded in respectively this side stand 1 bottom (can be welded in this two stationary pipes 11,12 bottoms), this the first bundle 31 is comprised of upper bundle stroma 311 and the upper stay 312 that the middle part has respectively recess, should be fixed in bundle stroma 311 corresponding sections on this by screw threads respectively in upper stay 312 two ends, should be welded in respectively this two stationary pipes 11 in upper bundle stroma 311 both sides, 12, this the second bundle 32 is comprised of lower bundle stroma 321 and the lower stay 322 that the middle part has respectively recess, this time stay 322 two ends are fixed in this time bundle stroma 321 corresponding sections by screw threads respectively, and this time bundle stroma 321 both sides are welded in respectively in the middle of this two reinforced rib 4.The effect of described Shu Zi is that with bundle stroma and stay recess inclusion in these standpipe of front fork both sides, the recycling screw locking reaches the effect of being fixedly clamped.
Be fixed in this standpipe of front fork for the ease of these front shelf, should upper bundle stroma 311 and recess of upper stay 312 be respectively equipped with the rubber sheet gasket of this standpipe of front fork of being convenient to be fixedly clamped, this time bundle stroma 321,322 and the recess of lower stay also be respectively equipped with the rubber sheet gasket of this standpipe of front fork of being convenient to be fixedly clamped, even Shu Zi is dismantled in design like this, leave no trace on the standpipe of front fork, do not destroy the bicycle overall appearance.
This side stand also is provided with for the fixing fixed orifice of goods basket sidepiece, and this lower supporter is provided with for the fixing slotted hole 5 of goods basket bottom, and the design of this slotted hole is the goods basket bottom centre of different size is fixed in the center of this lower supporter.
