Abstract

The utility model relates to a movable position connecting device for an article-carrier of a bicycle. A connecting seat is fixedly arranged at a carrier rod end of the article-carrier; through a positioning screw which is screw installed on the connecting seat, the utility model is screw inserted into a position of a control adjusting tab in a concave groove or a concave arc on the adjusting tab of a rectangular groove of the connecting seat; the article-carrier can be conveniently used by different specification of bicycles. The utility model has the advantages of simple structure, easy fabrication and convenient position adjustment, is suitable to be matched with various specification of bicycles, is favorable for reducing production cost and simplifying production technology and is convenient to bind at article carrying; the article carrying process is safe; the utility model is suitable for industrialized production and can be used as a product to replace the existing article-carrier of a bicycle.

Description

The activity bit tipping of automatic vehicle shelf is put

The utility model is that a kind of activity bit tipping of automatic vehicle shelf is put.

Because the structure feature of vehicle-mounted framework voluntarily, be the carrying large-sized object is being provided under the limit scope or, is indispensable main accessory on a kind of bicycle therefore than heavy articles usefulness not form to arrest.It is installed on the seat rear side usually and extends behind car, generally speaking, luggage carrier is that the position tipping that utilizes carrier bar not hold to be set firmly is put and linked with the wheel nave both sides and produce positioning action, because this tipping is put and is not had a position tonality, the luggage carrier that bicycle was equipped with of therefore different wheels footpath specification just exists difference, its carrier bar length promptly becomes the difference place of wheel footpath specification, at present be to cooperate the automatic vehicle shelf of making all size according to the existing specification of bicycle, and the luggage carrier of every kind of size can not be general, the luggage carrier that the producer must purchase all size is selected to provide to install, and has uneconomical in fact and takies the puzzlement of big quantity space; In addition, existing luggage carrier is body of rod moulding or plate, body of rod combination forming mostly, and the leaf that can not provide rope to tie up object causes effectively to bring into play and arrests the bundle positioning action, the loading poor stability, and safety performance is low.

The purpose of this utility model is to overcome the deficiency of prior art and provides a kind of activity bit tipping simple in structure, automatic vehicle shelf that processing and manufacturing is easy, easy to install to put.

Main purpose of the present utility model is to adopt following proposal to realize: do not hold in the luggage carrier carrier bar to set firmly a connecting seat, screw in the groove on the tab be plugged in the Connection Block rectangular channel or the position of the control tab in the concave arc by the set screw of spinning on Connection Block, conform with the luggage carrier that different bicycle specifications are used so that provide.

Secondary objective of the present utility model is achieved in that groove or the concave arc on the tab take the bi-directional symmetrical setting so that when installing unlikely generation just, the position of reverse side or left and right side is to restriction.

Concrete structure of the present utility model describes in detail below in conjunction with accompanying drawing:

Accompanying drawing 1 is the utility model three-dimensional exploded view and assembly drawing.

Accompanying drawing 2 is an assembling of the present utility model position profile control diagrammatic sketch.

See accompanying drawing 1,2, the utility model is by luggage carrier 2, joint seat 3, tab 4, fixed plate 5, steel ball S, spring R, bolt A forms, described joint seat 3 is T type bodies that both sides are provided with arc edge 31,31 at arc edge be provided with again one vertically to one of rectangular channel 32, then there is mould the lateral to the alveolus 33 that is connected to rectangular channel 32, tab 4 just is, the rectangular lamellar body that sets up several grooves or concave arc 41 on the reverse side separately, and establish size scale at 41 right positions row of groove or concave arc, the latter end is established one and is cooperated the sealed circular hole 42 of wheel nave, and put 43 towards establishing to dash forward in rim surface, fixed plate 5 is 8 font lamellar bodies with hypomere circular hole 51 affixed joint seats 3, section is provided with one for the rope hook on it, the horizontal ellipse shape slotted eye of hanging 52, bolt A is an interior hexagonal key of not holding tapered A, and the carrier bar 21 of joint seat 3 by its both sides arc edge 31 and luggage carrier 2 both sides be parallel do not hold 211 affixed, tab 4 is placed through in its rectangular channel 32, steel ball S, spring R embeds in the alveolus 33 successively, and bolt A is placed through in the circular hole 51 of fixed plate 5 lower ends and in the alveolus 33 of spinning on Connection Block 3 and with tab 4, fixed plate 5 is fixed on the Connection Block 3.

Using method of the present utility model is sketched in down, when need are adjusted the length of luggage carrier both sides carrier bar, only need unscrew bolt A, make tab 4 in Connection Block 3, slide in the rectangular channel 32, then can adjust the length of luggage carrier both sides carrier bar easily, to adapt to the equipped of different wheels footpath bicycle.Simultaneously, be installed on the joint seat 3 owing to will be provided with the fixed plate 5 of horizontal ellipse shape groove 52 by bolt A, therefore, when being convenient to loading, rope or elastic cable place in the ellipse shape groove 52 and will be tied up firmly by loading, reliability when improving loading and the operation ease when tying up.

In sum, the utility model is simple in structure, processing and manufacturing is easy, position adjustments is convenient, it is supporting to be suitable for all size bicycle, help reducing production costs, simplify production technology, and be convenient to tie up during loading, loading is safe and reliable, be suitable for suitability for industrialized production, can be used as the renewal product of existing automatic vehicle shelf.
