Abstract

The utility model relates to a bicycle folding structure which comprises a folding base A, a folding base B and a rotation shaft. The corresponding sides of the folding base A and the folding base B are connected in a rotary mode through the rotation shaft, a catching mechanism for achieving locking or unlocking of the folding base A and the folding base B is arranged between the other corresponding sides of the folding base A and the folding base B and comprises a rotation handle used for locking or unlocking the folding base A and the folding base B, and the bicycle folder is characterized in that a clamping plate is fixed on the inner side of the rotation handle, an elastic pulling hook capable of being connected with the clamping plate in a clamped mode is installed on the folding base A, and an ejecting plate used for ejecting the elastic pulling hook to enable the elastic pulling hook to be separated from the clamping plate is installed on the clamping plate. The bicycle folding structure has the advantages that a mechanism for limiting a folder handle to be naturally opened is additionally installed on the folding structure, so that the bicycle folding structure has the self-locking function, and safety factors of a bicycle can be improved.

Description

A kind of bicycle folding structure

Technical field

The utility model belongs to folding bicycle technical field, particularly relates to a kind of bicycle folding structure.

Background technology

Bicycle is current the most frequently used manpower transportation, use extremely extensive, common bicycle often volume ratio is larger, bicycle parking, carry, carry very inconvenient, therefore, people have designed folding bicycle, are mainly by the folding volume that dwindles bicycle to cycle frame, make bicycle there is storage area little, be convenient to the advantage of carrying.Folder is the main accessory on folding bicycle, and the quality of folder can determine the total quality of folding bicycle to a certain extent.In conventional art, use the most general folder to generally comprise two foldable base that can lock or open, be arranged on the rotating shaft that two foldable base one sides are rotationally connected for realizing two foldable base, be arranged on the locking mechanism that two foldable base opposite sides can be realized two foldable base lockings or open, catch gear comprises turning handle, by rotation turning handle, can realize two foldable base lockings or open, under two foldable base locking states, be (this state is also the use state of folding bicycle) under folding bicycle frame deployed condition, the position of turning handle is generally to fit with the vehicle frame of folding bicycle, in order to make the integral structure of folding bicycle stable, prevent turning handle automatic rotating and locking mechanism is opened under vibration or the impact of other factors, avoid accident in the process of riding to produce, on the vehicle frame of existing folding bicycle, near on the position of folder, safety device is all installed, safety device mostly is the circular body on its that black plastic makes with horizontal hook groove, after the vehicle frame of the turning handle laminating folding bicycle of locking mechanism, need to rotate above-mentioned circular body, so that turning handle enters hook groove from the sidepiece of circular body, by the method, prevent turning handle automatic rotating, this safety device has not only increased the control step in folder use procedure, use inconvenient, and can have a strong impact on the overall appearance of folding bicycle.

Summary of the invention

The utility model provides the safety device of a kind of folder use inconvenience and the use of cooperation folder to affect the technical matters that bicycle is attractive in appearance a kind of have auto-lock function, easy to use, the succinct bicycle folding structure attractive in appearance of profile is provided for solving the technical matters existing in known technology.

The technical scheme that the utility model is taked for the technical matters existing in solution known technology is: a kind of bicycle folding structure, comprise A foldable base, B foldable base and rotating shaft, the corresponding side of described A foldable base and B foldable base is rotationally connected by described rotating shaft, between the corresponding opposite side of described A foldable base and B foldable base, be provided with the locking mechanism that can realize described A foldable base and the locking of B foldable base or open, described locking mechanism comprises for locking or beat the turning handle of described A foldable base and B foldable base, it is characterized in that: the inner side of described turning handle is fixed with clamp, in described A foldable base, be provided with can with the elastic dialing hook of described clamp clamping, on described clamp, be provided with for top compression elasticity and dial the top board that hook departs from elastic dialing hook and clamp.

The utility model can also adopt following technical scheme:

Described elastic dialing hook comprises adapter plate, bearing pin, spring and coupler body.

Described top board is arranged on described clamp by vertical chute, is provided with the spring that clamp is resetted between described clamp and described top board.

The top of described turning handle is stretched out on the top of described top board, and the top of described top board is connected with button.

Advantage and the good effect that the utlity model has are: because the utility model adopts as above technical scheme, design a kind of folding bicycle foldable structure with auto-lock function, on this foldable structure, install the mechanism naturally opening for limiting folder handle additional, make bicycle folder there is auto-lock function, can improve the safety factor of bicycle.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the connection structure schematic diagram of top board and clamp in the utility model.

In figure: 1, A foldable base; 2, B foldable base; 3, turning handle; 4, clamp; 5, elastic dialing hook; 6, top board; 7, vertical chute; 8, spring; 9, button.

The specific embodiment

For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:

Refer to Fig. 1 and Fig. 2, a kind of bicycle folding structure, comprise A foldable base 1, B foldable base 2 and rotating shaft, the corresponding side of A foldable base 1 and B foldable base 2 is rotationally connected by rotating shaft, between A foldable base 1 and the corresponding opposite side of B foldable base 2, be provided with the locking mechanism that can realize 2 lockings of A foldable base 1 and B foldable base or open, locking mechanism comprises for locking or beat the turning handle 3 of A foldable base 1 and B foldable base 2, the inner side of turning handle 3 is fixed with clamp 4, in A foldable base 1, be provided with can with the elastic dialing hook 5 of clamp 4 clampings, on clamp 4, be provided with for top compression elasticity and dial the top board 6 that hook 5 departs from elastic dialing hook 5 and clamp 4.After above-mentioned turning handle 3 closures, elastic dialing hook 5 is automatic and be fixed on clamp 4 clampings on turning handle 3, now cannot outwards rotate turning handle 3, turning handle 3 self-lockings of folder; Press coping 6 downwards, the low side top compression elasticity of top board 6 is dialled hook 5, and elastic dialing hook 5 departs from clamp 4, now can open turning handle 3, with this, can effectively avoid turning handle 3 to open because of bicycle vibrations or non-artificial external force, improves the safety factor of bicycle.
