Abstract
The utility model relates to a safety locking mechanism of a folding joint. One end of a hinge axis of an eccentric handle draw bar of a slave connecting plate extends beyond the connecting plate to form a locking pin; the position of a main connecting plate, which is corresponding to the locking pin, is provided with a neck; the outer side of the main connecting plate is fixed with a fixed slideway, the locking pin can move in the slideway, and the force is applied on the locking pin by a spring toward the neck direction. The safety locking mechanism is characterized in that a safety lock is added to the traditional folding joint, even when an eccentric locking draw bar is dead, the joint can not be opened, and the safety can be enhanced.
Description
Technical field
The utility model relates to the locking device that two sections rod members connect folding joint
Background technique
Now comparatively popular folding joint all is to fix a connecting plate (for ease of distinguishing and being referred to as main connecting plate and secondary connecting plate) on two sections rod members respectively, and a side of two connecting plates is hinged.The Camlock pull bar that the opposite side hinge of secondary connecting plate is made of pull bar and eccentric handle has the Ka Tai that can block eccentric handle on the main connecting plate.When two upper junction plates closed up, the eccentric handle of secondary connecting plate may be stuck on the Ka Tai of main connecting plate, moved handle and by pull bar two connecting plate tensions was also locked together.The operation of opening or locking of this folding joint is all very convenient, but this class folding joint is used on the vehicle frame of folding bicycle more, the mountain peak is winnowed with a dustpan stressed very greatly during bicycle running, may cause the fracture when too stressed of Camlock pull bar, slippage and causes bicycler's danger.
Summary of the invention
The purpose of this utility model provides a kind of safe locking device that has added the folding joint of locking mechanism, to guarantee that folding joint still is in locking state when pull bar fracture or the slippage.
The utility model is realized as follows, two connecting plate one sides are hinged, the Ka Tai that can block eccentric handle is arranged on the main connecting plate, the pull bar that hinged eccentric handle drives on the secondary connecting plate, hinge axis one end of hinge pull bar stretches out and constitutes bayonet lock outside the connecting plate, corresponding bayonet lock position has the draw-in groove that can radially enter bayonet lock on the main connecting plate, main connecting plate outside ground way, it is removable that front end is that the lock pin on inclined-plane is in the slideway, be equipped with in the slideway the spring of lock pin, fix a handle on the lock pin to the draw-in groove direction application of force.
The utility model has added a lock pin in traditional folding joint one side, when two connecting plates close up, bayonet lock collides the inclined-plane of lock pin front end in laterally entering the draw-in groove process, promote to move behind the lock pin, after bayonet lock enters draw-in groove, lock pin resets according to spring force bayonet lock is enclosed in the draw-in groove and can not withdraws from, even the Camlock pull bar damage to lose efficacy and can guarantee still also that two upper junction plates are in and close up the state folding joint and can not open.Open folding joint as need, the handle of pulling lock pin retreats and gets final product.The safe locking device of described folding joint is easy to operate, has improved the Security of folding joint.

Fig. 2 is that the A of Fig. 1 is to view;
Fig. 3 is the plan view that folding joint closes up state;
Fig. 4 is that the B of Fig. 3 is to view.
Embodiment
Fix main connecting plate 2a and secondary connecting plate 2b on two sections rod members 1 respectively, two plates, one side is hinged, and the hinged Camlock pull bar 3 that is made of eccentric handle 3a and pull bar 3b of the opposite side of secondary connecting plate 2b has the card platform 4 that can block eccentric handle 3a on the main connecting plate 2a.Hinge axis 10a one end of hinged pull bar 3b stretches out and constitutes bayonet lock 10 outside the connecting plate, corresponding bayonet lock position has the draw-in groove 6 that can radially enter bayonet lock on the main connecting plate, main connecting plate 2a outside ground way 5, it is removable that front end is that the lock pin 9 on inclined-plane is in the slideway 5,8 pairs of lock pins of spring is housed to the draw-in groove 6 direction application of forces in the slideway 5.Fix a handle 7 on the lock pin 9.Slideway 5 one sides have a locating notch 11, and pull handle 11 makes moves and rotate lock pin behind the lock pin and handle 7 is stuck in can keep bayonet lock 9 to remove locking functions in the locating notch 11.
