Description
Technical field
The utility model relates to the folding and locking field of pipe fitting, particularly folding the and locking of the pipe fitting of folding bicycle.
Background technique
The folding joint of pipe fitting and locking device are more is used for present folding bicycle pipe fitting.The folding joint and the locking device of existing folding bicycle have two kinds usually: a kind of is that structure is better simply, it is the eccentric quick detach of the activity that is hinged with on folding joint hinge opposite, pull quick detach and rotate with hand and two folding joints could be locked with defeating then, will rotate eccentric wheel when unclamping earlier up carries then and rotates whole quick detach group again and just can open, this folding joint and locking device since quick detach and quick detach axle be movably hinged, and the quick detach axle is movably hinged with folding joint, therefore very inconvenient when the operation quick detach is locked or opened folding joint, often to could or open folding joint locking by several actions, and this folding joint is for safety, profile is designed to square more, so outward appearance is relatively poor relatively; Another kind is also folding joint and a locking device preferably of the more convenient outward appearance of operation, but this folding joint and locking device have caused processing difficulties, have manufactured the cost height owing to the structure more complicated, therefore difficult widely-used on market, and because processing is difficult, usually causing when producing in batches does not require to make the folding joint lock not tight because of processing reaches, if the folding joint lock usually on the folding bicycle pipe fitting is not tight, might cause the injury of health to the rider.
The model utility content
The technical problem that solves:
Be at the deficiencies in the prior art order of the present utility model, design that a kind of easy to operate, coupling mechanism force is strong, beautiful shape, simple in structure, easy pipe fitting processed folding joint and locking device thereof.
The technological scheme of technical solution problem:
A kind of pipe fitting folding joint and locking device thereof, two end faces are connected with the folding joint of pipe fitting, first folding joint and second folding joint are hinged by a hinge, be provided with two auricles parallel to each other in the first folding joint edge, form groove in the middle of two auricles, the compact heap that head end is provided with the inclined-plane places in the groove, and the hole that No. two hinges pass in the middle part of the compact heap is hinged on auricle and last with compact heap; Second folding joint is provided with another inclined-plane that cooperates the inclined-plane on the compact heap to compress in corresponding edge; Also be provided with driver part and elastomer in addition, driver part can drive the compact heap tail end makes compact heap rotate and produce lever around No. two hinges, the lever that produces will make the inclined-plane of compact heap head end compress another inclined-plane of relevant position on second folding joint, thereby first folded formation and second folded formation are locked together, and elastomer plays reset response when unclamping compact heap.
Described driver part is provided with the handle of easy-to-operat, and handle can also design in the form of slot, and groove shape handle and eccentric shaft combination place are polygonal or non-circular shape.
Described elastomer is a torsion spring, the torsion spring string on No. two hinges and an end push against the first folded formation the other end and push against compact heap, torsion spring plays reset response when unclamping compact heap.
Described folding device also has been equipped with the adjusting screw of regulating the effect of locking gap, adjusting screw both can be contained in the place, inclined-plane of second folding joint, also can be contained in the place, inclined-plane of compact heap, the effect of adjusting screw is the degree that compresses of regulating between the compact heap and second folding joint.
The described first folding joint hinge side edge has been provided with the muscle of reinforing function, and the second folding joint corresponding position is provided with steps down.
The top of described first folding joint and second folding joint and bottom are arc, and first folding joint is line segment and the tangent angled transition of top arc by hinge side, reaches slick and sly more effect attractive in appearance.
Also be provided with on second folding joint playing the safety button of safety effect after the device locking, safety is detained by screw on the safe Button Block on second folding joint.
As further improvement of the utility model, driver part, compact heap, No. two hinges etc. also can place pipe fitting inside, make pipe fitting folding joint outward appearance more succinct, attractive in appearance like this.
Beneficial effect:
Pull the handle on the driver part, can realize unclamping or locking folding joint, it is very convenient to operate; Compact heap compresses folding joint by lever, so coupling mechanism force is strong; The locking device number of spare parts is less, so processing technology is simple, and it is also lower to manufacture cost; The folding joint configuration design is in the arc-shaped and streamlined, and outward appearance is more attractive in appearance.
