Description

Folding bicycle

Technical Field

The utility model relates to a bicycle technical field especially relates to a folding type bicycle.

Background

The folding bicycle of prior art includes front beam and preceding upper beam, is connected through the scray between the two, locks the scray through the hasp, but this kind of structural reliability is lower, and during the use, the hasp probably produces not hard up, and then leads to the scray pine to take off for the personnel of riding have the potential safety hazard.

Disclosure of Invention

The utility model discloses the technical problem that will solve is: provided is a highly reliable folding bicycle.

the utility model adopts the technical proposal that: the utility model provides a folding type bicycle, includes front beam and preceding upper beam, be connected through the scray between front beam and the preceding upper beam, just still be equipped with the hasp that is used for locking the scray on the scray, the hasp still including fixed stop pin, the sliding connection that sets up on the hasp in the hasp and be used for catching on the auto-lock slider of stop pin and be used for driving the auto-lock slider and reset the reset spring who catches on the stop pin.

Preferably, the unlocking end of the self-locking sliding block for unlocking by a user extends out of the lock catch and is close to the wrench part on the lock catch.

Preferably, the unlocking end is arc-shaped.

Preferably, it further comprises a limiting member for limiting the moving distance of the unlocking end.

Compared with the prior art in the structure more than adopting, the utility model has the advantages of it is following: a locking pin is arranged in the lock catch, and a sliding self-locking sliding block can hook the locking pin, so that double locking can be realized, and the reliability is high.

The unlocking end extends out and is close to the wrench part of the lock catch, so that a user can push the self-locking sliding block to unlock when preparing to pull the lock catch, and the use is more convenient.

The unlocking end is set to be arc-shaped, so that hands of a user cannot be injured when the user unlocks.

A limiting part is arranged, so that the self-locking sliding block cannot move too much during unlocking.

Detailed Description

The present invention will be further described below with reference to specific embodiments, but the present invention is not limited to the following specific embodiments.

The utility model provides a folding type bicycle, includes front beam 1 and preceding entablature 2, be connected through scray 3 between front beam 1 and the preceding entablature 2, just still be equipped with hasp 4 that is used for locking the scray on the scray 3, wherein:

The folder 3 comprises a first folding part and a second folding part, the first folding part is fixedly connected to the front beam 1, the second folding part is fixedly connected to the front upper beam 2, and the first folder is hinged to the second folder;

The lock catch 4 is arranged between the first folder and the second folder and used for locking the first folder and the second folder;

A locking pin 5 is fixedly arranged on the lock catch 4, a sliding groove is arranged in the lock catch 4, a sliding rod is arranged in the sliding groove, one end of the sliding rod penetrates through the lock catch 4 and is fixed on the second folding portion, and a reset spring 7 and a self-locking sliding block 6 sequentially penetrate through the other end of the sliding rod and are connected to the sliding rod in a sliding mode.

The end, far away from the sliding rod, of the self-locking sliding block 6 is provided with an unlocking end 8, the unlocking end 8 is arc-shaped, a limiting part 10 is fixedly arranged in the lock catch 4 and embedded into the unlocking end 8, so that the moving position of the self-locking sliding block 6 can be limited, and the unlocking end 8 penetrates out of the lock catch and penetrates out of a wrench part 9 of the lock catch 4.

The working principle of the application is as follows: when the lock catch is buckled to lock the first folding part and the second folding part, the locking pin in the lock catch can extrude the hook grabbing part on the self-locking sliding block, so that the locking pin is embedded into the hook grabbing part of the self-locking sliding block, double locking is realized, when the lock catch is required to be unlocked, the unlocking end of the self-locking sliding block is firstly required to be pressed by a user, the hook grabbing part of the self-locking sliding block is separated from the locking pin, then the lock catch is opened, and the unlocking can be conveniently realized.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
