Description

Bicycle luggage carrier is adjusted structure

Technical field

The utility model relates to bicycle luggage carrier, particularly relates to a kind of have fixed type and two kinds of bicycle luggage carriers adjustment structures of using form and fixed type shelf still to have two kinds of regulative modes of adjustable type.

Background technology

Traditional shelf, it mainly is the integral type manufacturing that bearing panel and assembling bar are fixed, in the bearing panel both sides is the bracing frame that extends downwards, so as to fixing with back vent and wheel shaft pivot knot, the bearing panel leading edge is a pair of hinged arm of projection forward then, and cooperate collar and must be fixing with the combination of seat cushion seat pipe, finish luggage carrier according to this and combine with the assembly of cycle frame.But with regard to the body frame structure for automotive of bicycle, because of the difference of its form, function, its specification, size are also variant mutually, so the stationary structure Chang Wufa of traditional shelves is applicable to the assembly of different vehicle frames, are its shortcomings.

By above-mentioned disappearance, there is industry to develop number No. 81205919 examination of proposition in " improvement of automatic vehicle shelf structure (one) " (as shown in Figure 1) on May 9th, 81 patent application case and gets permission patent, and patent is got permission in No. 81212606 examination of proposition in " adjustable bicycle luggage carrier " (as shown in Figure 2) on September 18th, 81 number of patent application, commonly use case by above-mentioned two and see it, though its setting by adjust bar 1 can reach the effect that luggage carrier is incorporated into different vehicle frames, but fixed type still has the few advantage of the preferable and sealed point of intensity, not and not the needing too big adjustment or must not adjust of most of luggage carrier 2 in conjunction with vehicle frame, so fixed type still is necessary, how to take into account the difficulty that solves into the anxious desire of industry.

Summary of the invention

Main purpose of the present utility model promptly is to eliminate above-mentioned each shortcoming, thereby provides a kind of bicycle luggage carrier to adjust structure, and form is used in two kinds of selections that make these shelf have fixed type or adjustable type.

For reaching this purpose, bicycle luggage carrier of the present utility model is adjusted structure and is comprised shelf, these shelf are established the tool carrying surface and are extended downward bipole body by these carrying surface both sides, two combination covers are established tool two through holes according to its shelf body of rod insert group direction, combination cover middle position is also established the non-circular perforation groove of tool, and its connect groove towards lateral direction and form open slot, connect in the groove and be provided with at interval two vertically to through hole, the corresponding through hole position of open slot also is provided with arc-shaped slot, be beneficial to bolt cap or nut is worn lock, combination is overlapped with through hole for two body of rod insert groups of carrying surface supported on both sides frame and with punching press distortion or the fixed one of welding manner, two adjusts bar have several adjustment holes at interval, and section form is same as the combination cover and connects groove, but insert group is done flexible the adjustment and lock knot after adjustment is finished in combination cover groove.

Form is used in two kinds of selections that above structure design makes these shelf have fixed type or adjustable type, and the fixed type shelf still have the effect that two kinds of regulative modes are selected.

The specific embodiment

Below by specific embodiment to further specify structure design of the present utility model and technology.

As Fig. 3, shown in 4, a kind of bicycle luggage carrier is adjusted structure, mainly providing a kind of shelf 20 has concurrently and directly is locked on car body voluntarily or grafting adjust bar 30 and becomes the shelf lock that multistage selects to regulate and establish form, its shelf 20 carrying surfaces 21 both sides are the bracing frame 22 that extends downwards, this bracing frame 22 is established and is two bodies of rod 221,222 extend downwards, one combination cover 40 is according to its body of rod 221,222 insert group directions are established tool two through holes 41, middle position is also established the non-circular perforation groove 42 of tool, and its connect groove 42 towards lateral direction and form open slot 43, connect in the groove 42 also according to last, following appropriate location be provided with two vertically to through

hole

44,45, open slot 43 corresponding through

holes

44,45 positions also are provided with arc-shaped slot 46, combination cover 40 utilizes two bodies of rod 221 of through hole 41 for carrying surface 21 supported on both sides framves 22, behind 222 insert groups, utilize impact style or welding manner will make up the cover 40 and the body of rod 221,222 integrally combine;

Establish the some perforation adjustment holes 31 of tool on the pole face of two adjusts bar 30 at interval, and the peripheral shape of this adjust bar 30 is entirely identical to the shape of the non-circular perforation groove 42 of combination cover 40, make its adjust bar 30 get the perforation groove 42 of insert group in this combination cover 40, but and the flexible slippage adjustment of crossheading trench culture.

As shown in Figure 5, this a kind of bicycle luggage carrier is adjusted the one lock knot mode of structure and is: 40 through holes 44 are overlapped in the combination that shelf carrying surface 21 both sides integrally combine for the bracing frame utilization of extending downwards must be fixing with nut 52 pivots knot via combination cover 40 arc-shaped slots 46 other ends for the screw rod insert group of the back vent of bicycle, wheel shaft projection or circular hole 51 alignment and bolt 50; Other is the person, when shelf 20 block positions will be increased, overlap 40 through holes 45 for the screw rod insert group or circular hole 51 alignment of the back vent of bicycle, wheel shaft projection and bolt 50 must the other end be fixing with nut 52 pivots knot via combination cover 40 arc-shaped slots 46 with the combination of shelf one if its wheel rim is big; Reach list and establish effect with regard to two sections adjustment locks that shelf promptly have one combination cover.

As shown in Figure 6, another lock knot mode that this a kind of bicycle luggage carrier is adjusted structure is: the combination cover 40 that shelf carrying surface 21 both sides integrally combine for the bracing frame utilization of extending downwards connects groove 42 and must supply insert group adjust bar 30, and because of adjust bar 30 section forms and the identical and non-circular shape of groove 42 section forms, and make this adjust bar 30 only can do flexible adjust action and can't rotate arbitrarily, it is incorporated in the bigger bicycle body in wheel footpath bicycle luggage carrier 20 by adjust bar 30, its lock knot mode is that adjust bar 30 selects the suitable adjustment hole 31 and the through

hole

44 or 45 of combination cover 40 to utilize bolt 53 in advance, nut 54 lockings, adjust bar 30 adjustment holes 31 are for the back vent of bicycle again, the screw rod insert group of wheel shaft projection or circular hole 51 alignment are and fixing with bolt 55 and nut 56 pivots knot, and the structure that reaches bicycle luggage carrier is applicable to the assembling effect of different vehicle frames.

By above-mentioned combination, bicycle luggage carrier of the present utility model is adjusted structure and is had effect described as follows:

One, bicycle luggage carrier are adjusted combination kenel that structure has fixed type shelf and adjustable type shelf concurrently and are used effect, its formula shelf that no matter fix are used or the adjustable type shelf use all can, and on a shelf structure, can reach;

Its two, bicycle luggage carrier is adjusted structure still can have several sections regulating effect when fixing the formula shelf, and makes on its practicality more extensive.
