Abstract

A self-lock semi-automatic return side stand comprises a crossbeam, a footrest and a rubber collar for the footrest, which is characterized in that the rubber collar for the footrest is positioned on the crossbeam or a connection block between the footrest and the stand; the footrest and the crossbeam are hinged and the integrated structure is normally folded through a return device; a self-lock device consists of an envelop lock at the hinge position between the footrest and the crossbeam to perform self lock when the footrest stretches; the envelop lock is controlled by the return device and a lock control rod controlled by the rubber collar for the footrest. The structure improves the strength of the lock device, reduces processing precision and requirements for materials, eliminates the vibration of the footrest and achieves precise positioning and locking. The device is of higher safe reliability, precise and agile locking effect and convenient unlocking performance.

Description

Novel self-locking type S. A. return side stand

Technical field

The utility model relates to the improvement technology of side support of motorcycle, is specifically related to a kind of self-locking type S. A. return side stand.

Background technology

At present, the structure of motorcycle main side stand has all had bigger development, multi-form laborsaving main support and self-return side stand have successively appearred, but a series of problem appears in concrete enforcement, because of motor bike can be subjected to severe impact in operational process, require all necessary material that adopts high tenacity of parts of support frame, will make the hardness of material be subjected to great restriction thus, bring restriction for the service life of parts, wait the difficulty of bringing a series ofization for processing.To cause the potential safety hazard of a series ofization simultaneously.

Summary of the invention

The utility model is at deficiency of the prior art, a kind of external envelope structure with tapering is provided, and can bear violent collision, thereby long service life and can eliminate tolerance clearance, accurately steadily halt.Thereby really accomplish easy to operate, the stable i.e. novel self-locking type S. A. return side stand of band self-locking mechanism when supporting of Parking.

The technical solution adopted in the utility model is such, and promptly a kind of novel self-locking type S. A. return side stand comprises cross beam pole, oblique pin, pedal gum cover, it is characterized in that: the pedal gum cover is positioned on the contiguous block of cross beam pole or oblique pin and vehicle frame; Tiltedly pin and cross beam pole are connected as a single entity with the pivotally attached form, and keep folding state by Bringing-back mechanism under free state; Comprise self-locking mechanism, enveloping lock block and dead bolt that the oblique pin of maintenance that this self-locking mechanism is had by the hinged place at oblique pin and cross beam pole automatically locks when stretching constitute, and this lock dog is controlled by Bringing-back mechanism with by the lock dog control stalk of pedal gum cover control.

The utlity model has following advantage:

The utility model has improved the intensity of lockout mechanism owing to adopted internal taper external envelope structure, has reduced working accuracy and to the requirement of material.Make the elimination of rocking of oblique pin, reach the accuracy positioning and locking, have higher safe reliability.Make locking accurately freely, release is flexible.

In the accompanying drawing: the oblique pin 2-of 1-reset tension spring 3-torsion spring 4-lock dog 5-bolt and nut 6-coupling block 7-cross beam pole 8-pedal gum cover 9-lock dog control stalk.

The specific embodiment

Just the utility model is described in further detail with enforcement in conjunction with the accompanying drawings more below;

Referring to accompanying drawing, self-locking type S. A. return side stand comprises oblique pin (1), torsion spring (3), lock dog (4), lock dog control stalk (9), it is characterized in that lock dog (4) is movable with oblique pin (1) and connects.Tiltedly pin (1) is by bolt in the present embodiment, and nut (5) is articulated on the coupling block (6) with dead bolt, and the two ends of reset tension spring (2) are hung on oblique pin (1) and the coupling block (6); Lock dog (4) envelope is hinged on the oblique pin (1), and is resetted and the dead bolt of coupling block (6) entangled and make oblique pin locking by the torsion spring that is installed in oblique pin (1) (3); One end of lock dog control stalk (9) and pedal gum cover (8) are fixing, and the other end is pressed on the lock dog (4).During driving, when pin was stepped on pedal, lock dog control stalk (9) pressed down lock dog, removed the constraint to dead bolt, and oblique pin (1) can be rebounded under the effect of reset tension spring automatically, the state folding state when keeping driving.When oblique pin (1) went to the Parking position, lock dog (4) can accurately lock dead bolt rapidly under the effect of torsion spring (3).During if need unlock, lock dog control stalk (9) can force dead bolt to withdraw from lock dog (4) timely and accurately.Because lock dog has inner conical surface, can also make dead bolt can pass in and out lock dog accurately.The tapering of the conical surface is generally about the 0.5-10 degree.

Claims

1, a kind of novel self-locking type S. A. return side stand comprises oblique pin (1), cross beam pole (7) or plays contiguous block (6), the pedal gum cover (8) of oblique pin and vehicle frame; It is characterized in that: the pedal gum cover is positioned on the contiguous block of cross beam pole or oblique pin and vehicle frame; Tiltedly pin and cross beam pole are connected as a single entity with the pivotally attached form, and keep folding state by Bringing-back mechanism under free state; Comprise self-locking mechanism, enveloping lock block and dead bolt that the oblique pin of maintenance that this self-locking mechanism is had by the hinged place at oblique pin and cross beam pole automatically locks when stretching constitute, and this lock dog is controlled by Bringing-back mechanism with by the lock dog control stalk of pedal gum cover control.

2, novel self-locking type S. A. return side stand according to claim 1 is characterized in that: lock dog (4) is movable with oblique pin (1) and connects; Wherein tiltedly pin (1) is by bolt, and nut (5) is articulated on the coupling block (6) with dead bolt, and the two ends of reset tension spring (2) are hung on oblique pin (1) and the coupling block (6); Lock dog (4) envelope is hinged on the oblique pin (1), and is resetted and the dead bolt of coupling block (6) entangled and make oblique pin locking by the torsion spring that is installed in oblique pin (1) (3); One end of lock dog control stalk (9) and pedal gum cover (8) are fixing, and the other end is pressed on the lock dog (4).Because lock dog has inner conical surface, makes dead bolt can pass in and out lock dog accurately.

3, novel self-locking type S. A. return side stand according to claim 1, it is characterized in that: lock dog (4) has inner conical surface.
