Abstract

The utility model relates to the improvement of a clip for the luggage carrier of the bicycle. The improved clip for the luggage carrier of the bicycle is composed of three stages elastic clipping arms. A rear seat of the bicycle and a first stage clipping arm, the first stage clipping arm and a second stage clipping arm, and the second stage clipping arm and a third stage clipping arm are separately connected by a spring shaft. The clipping force is provided by the three stages torsion springs among the clipping arms, and the resultant force direction of the clipping force of the third stage clipping arm is downward. The torsion spring is arranged at the spring shaft to comprise a clip for the luggage carrier of the bicycle capable of pulling apart and turning up. The utility model has the advantage of clipping firmly the clipping articles and the articles with relatively large volume.

Description

Clip for luggage carrier of bicycle

The utility model relates to the rear bicycle folder after a kind of the improvement.

General-duty rear bicycle folder is the clamp that a metallic material is made at present, by spring shaft it is linked to each other with rear bicycle.The metal torsion spring is contained on the spring shaft.

This back seat folder is the one-level folder.After clamping object, clipped object spare is moved forward, particularly when clipped object spare volume bigger, or bicycle is when top pond uneven road surface travels, the easier clipped object spare that causes comes off.

The purpose of this utility model is to design a kind of multistage elasticity rear bicycle folder that caught object can be clamped downwards.

Clamp of the present utility model is made up of three grades of elasticity jig arm.The back seat of bicycle and one-level jig arm, one-level jig arm and secondary jig arm link with spring shaft respectively between secondary jig arm and three grades of jig arm.The metal torsion spring is installed on the spring shaft.Gripping power is to be provided by three grades of torque springs between jig arm, and the Clamping force resultant direction of one, two, three jig arm is downward.

This rear bicycle folder can make the bigger object of clipped object spare, particularly volume that significant clamping effect is arranged, and has overcome present general-duty back seat folder effectively, the shortcoming of grip difference.

Description of drawings:

Figure one presss from both sides the working state schematic representation of a kind of embodiment for rear bicycle.

Figure two is a structural representation.

Figure three is that the A of figure two is to view.

Figure four is the view that quits work.

Figure five is the structural representation of another kind of embodiment.

Below in conjunction with accompanying drawing the utility model is further described.

Referring to figure one, figure two, figure three, 1 is the bicycle base, and one-level jig arm 3 is made by the steel wire of two diameter 4mm, long 80mm, and two steel wire spacing 70mm, two on steel wire is made the garden ring-type respectively, and links to each other with

spring shaft

2,4 respectively.Secondary jig arm 5 is stamped to form by the sheet steel of thickness 1.5mm, two limits have 10mm wide tear the limit open, along two ends of long axis direction, the hole, garden of diameter 9mm is arranged, respectively with the mounting spring axle.One-level spring 8, two-level spring 9 respectively have two, and the number of turn is 15, spring external diameter 14mm, and internal diameter 10mm is enclosed within on the spring shaft, and spring one end is fixed by the pin on the axle, and an end is stuck in the edge of jig arm.Three grades of jig arm 7 are made by the steel wire of diameter 3.5mm, long 200mm, and wide 90mm, there are two stulls the centre, and front end is little is bent downwardly for folder, to compress clipped object spare.Three grades of springs 10 are two, and are identical with the I and II spring, are installed on the spring shaft 6.The present embodiment spring shaft is made by the round steel of diameter 8mm.The back seat folder can be formed a complete production network by Bicycle Plant and rear bicycle.

Figure five is that of the present utility model another implemented illustration.Form by three grades of jig arm.11 is the rear bicycle stull among the figure, and 12 for back seat folder base plate, makes with the sheet steel of thickness 2mm, and stull is connected with back seat with base plate by U-shaped screw 13.The one-level jig arm is wide to be 100mm, is made by the steel wire of diameter 5mm; The secondary jig arm is wide to be 110mm, and long 90mm is stamped to form by the sheet steel of thickness 1.5mm, and the limit is torn on two limits open; Three grades of jig arm are made by the steel wire of diameter 4mm, wide 120mm, long 200mm.It is identical that the spring that present embodiment is selected for use and spring shaft and embodiment one select for use.This rear bicycle folder can be produced separately, is installed on the rear bicycle of producing and using.

Claims

1, a kind of rear bicycle folder of forming by clamp and spring, it is characterized in that clamp is by one-level jig arm 3, secondary jig arm 5 and three grades of compound folders that jig arm 7 is formed, one-level jig arm 3 and secondary jig arm 5, link with spring shaft respectively between secondary jig arm 5 and three grades of jig arm 7, torsion spring is housed on the spring shaft, makes jig arm at different levels produce downward making a concerted effort.
