Abstract

The utility model relates to a chair frame clamping seat for an easily assembling bicycle, which comprises a clamping body, a supporting seat and a base seat which is positioned at the lower part of the supporting seat and fixed on the supporting pipe of a chair seat. An assembling bolt passes through the base seat and the supporting seat from bottom to top and is fixed on the clamping body, two punch holes are arranged on the clamping body, one pair of clamping columns whose directions are opposite, outer end are provided with slopes and inner end are provided with reverse inserting grooves are arranged in each punch hole, and a spring is clamped between the clamping columns. When the utility model is used, the chair frame aligns and clamps the slope and is pressed, and the clamping column is shrunk into the clamping body; after the chair frame is fallen into the groove of the supporting seat, the clamping column bounces out again, and the chair frame is fixed; when the clamping column is pressed into the clamping body by hand, the chair frame can be carried down from the upper part, and the utility model is convenient to assemble and disassemble.

Description

Bicycle chair frame holder easy to assembly

The utility model relates to a kind of bicycle chair frame holder easy to assembly.

Current, bicycle is adopted by consumers in general, wait the important performance except possessing lightweight and safety, also to consider to provide the customer can remove voluntarily and assembling and possibility, especially if can go out to carry or when going home to collect, can decompose rapidly or assemble, will be the target that consumers in general pursued, though a kind of so-called fast disassembly type bicycle is arranged now, but can only be with wheel, handlebar is separated fast, but bicycle seat, the but way of none convenient dismounting, and bicycle seat, be positioned at the vehicle frame stage casing, bulky, carry inconvenience, and how to be fixed on the vehicle frame with bolt and intermediate plate, must use spanner when pulling down, instruments such as screwdriver can not reach without instrument with regard to dismountable and installation seat support, so very inconvenient.

The purpose of this utility model is that a kind of bicycle chair frame holder easy to assembly will be provided, and it can be the seat support of dismantled and assembled bicycle without instrument, thereby is easy to carry, preserves and use.

The purpose of this utility model is achieved in that the bicycle chair frame holder that this is easy to assembly, by clamp, bearing and be positioned at the bearing bottom and be fixed on the pedestal that seat support is in the charge of and constitute, assembling bolt from bottom to top, pass pedestal, bearing, be fixed on the clamp, on clamp, be provided with two perforation, it is opposite to be provided with a pair of direction in each perforation, the outer end has the inclined-plane, and the inner has the folder post of reverse caulking groove, and the folder intercolumniation accompanies spring, during use, the chair frame is aimed at folder post inclined-plane press down, then press from both sides in the post retraction clamp, after the chair frame drops in the bearing groove, the folder post ejects again, and the chair frame is maintained static; Be pressed in the clamp when pressing from both sides post with hand, the chair frame can be taken off easy accessibility by top.

The utility model has following advantage:

1, because each on the clamp pressed from both sides post, and the outer end is provided with the inclined-plane, and the inner withstands on the spring, when the chair frame that has vehicle seat presses down, in the folder post retraction clamp, treat that the chair frame drops on the bearing after, the folder post stretches out again under action of the spring again, the chair frame is firmly clamped fixing, so it is easy that vehicle seat is installed.

2, owing to need pull down vehicle seat the time, as long as the folder post that the user will be exposed is pressed in the clamp, can make clip slot open, the chair frame that will have vehicle seat is taken off by top, so vehicle seat takes off easily.

3, because of the dismounting vehicle seat all must can not carry out by any instrument smoothly, thus easy to use, and simple in structure, make easily; In addition, because of fitting with cambered surface between bearing and pedestal, and with bolted connection, pedestal is provided with Long Circle bolt stroke hole, so vehicle seat is tilted forward and back within the specific limits, satisfies different needs.

The utility model concrete structure is fallen by following enforcement and accompanying drawing provides:
