Abstract
The utility model discloses a folding joint, which comprises an upper connecting plate and a lower connecting plate, wherein the upper connecting plate and the lower connecting plate are hinged at one side through a hinge shaft, a handle is hinged on the other side of the lower connecting plate, the front end of the handle is hinged with a ball head connecting rod, a ball head seat is fixed at the other side of the upper connecting plate, and the upper connecting rod is extruded into the ball head seat through the ball head connecting rod, so the upper connecting plate and the lower connecting plate are closed and tightly locked. The ball head seat consists of a base and a ball head bowl embedded in the base, the base and the upper connecting plate are integrally formed, the base and the ball head bowl are made of different materials, and the base has higher hardness and better abrasion resistance performance than the ball head. The ball head connecting rod consists of a ball heat screw rod and a rod seat of the connecting rod with internal screw threads, the ball head screw rod is screwed into the rod seat of the connecting rod for regulating the length of the ball head connecting rod, and a torsional spring is sheathed on the rod seat of the connecting rod. When the joint of the utility model is unfolded, the handle and the connecting rod are separated, the bruised finger injury caused by improper operation is prevented, and the collision deformation of projected parts is prevented.
Description
Technical field
The utility model relates to a kind of folding joint, the folding joint that especially a kind of folding bicycle uses.
Background technology
Folding joint is widely used in the folding bicycle, usually realize its fixed function by a pair of connecting panel that is hinged, as shown in Figure 1, existing a kind of folding bicycle folding joint is to be hinged in a side by two connecting panels, the hinged one handle of opposite side lower connecting plate, the hinged connecting rod of upper junction plate.Handle and connecting rod are hinged at the other end.This structure is a four-bar linkage structure, when launching joint, the binding face of two connecting panels is parallel, and the triangle that handle becomes with connecting rod protrudes in the binding face of two connecting panels, when careless behaviour did, the triangle that the binding face of handle and connecting rod and connecting panel constitutes may weigh finger wounded.This joint is used for bicycle, and outstanding triangle handle and connecting rod be collision deformation very easily.
Summary of the invention
The purpose of this utility model be to carry the arch a kind of prevent to weigh wounded the finger and collision-deformed folding joint.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of folding joint comprises that articulated axle is hinged on the upper junction plate and the lower connecting plate of a side, the hinged one handle of lower connecting plate opposite side, the hinged ball head connecting rod of handle front end; The upper junction plate opposite side is fixed a ball cap, is expressed in the ball cap by ball head connecting rod, makes upper junction plate and lower connecting plate closed and locked.
Described ball cap is made up of base and the bulb bowl of inlaying wherein.
Described base and upper junction plate are integrally formed, and base is different with the material of bulb bowl, and the material of base is higher and wear-resisting than bulb bowl hardness.
Described ball head connecting rod is made up of ball screw and the connecting rod pole socket that has negative thread, and ball screw is screwed into the length that the connecting rod pole socket is regulated ball head connecting rod.
Be with a torsion spring on the described connecting rod pole socket.
Stop screw restriction handle is installed on the described base crosses the position at dead point.
Folding joint of the present utility model, when launching joint, handle separates with connecting rod, prevents that behaviour from doing improper weighing wounded and pointing and prevent to give prominence to by collision deformation.
Description of drawings
Fig. 1 is that existing a kind of folding bicycle folding joint launches scheme drawing.
Fig. 2 is the perspective view of the utility model folding joint.
Fig. 3 is the locking state part sectional view of the utility model folding joint.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Shown in Fig. 2,3, folding joint of the present utility model comprises that articulated axle 1 is hinged on the upper junction plate 2 and the lower connecting plate 3 of a side, the hinged one handle 4 of lower connecting plate 3 opposite sides, the hinged ball head connecting rod 5 of handle 4 front ends; Upper junction plate 2 opposite sides are fixed a ball cap 6, are expressed in the ball cap 6 by ball head connecting rod 5, make upper junction plate 2 and lower connecting plate 3 closed and locked.Described ball cap 6 is made up of base 6a and the bulb bowl 6b that inlays wherein.Base 6a and upper junction plate 2 are integrally formed, and base 6a is different with the material of bulb bowl 6b, and base 6a is higher and wear-resisting than bulb bowl 6b hardness.Described ball head connecting rod 5 is made up of ball screw 7 and the connecting rod pole socket 8 that has negative thread, and ball screw 7 is screwed into the length that connecting rod pole socket 8 is regulated ball head connecting rods 5.Be with a torsion spring 9 on the described connecting rod pole socket 8.
When turning handle 4 made ball head connecting rod 5 compress ball cap 6, last lower connecting plate was just compacted, regulated the size of the adjustable in length coupling mechanism force of ball screw 7.Conveniently enter ball cap 6 for ease of ball head connecting rod 5, add a torsion spring 9 on the connecting rod 8 and make ball head connecting rod 5 keep certain angle, when turning handle 4, ball head connecting rod 5 is just compressed in the ball cap 6 automatically.Stop screw 10 restriction handles 4 are installed on the base 6 cross the position at dead point.
Be intensity that guarantees pressure and face and the paint coating of avoiding destroying pressure and face, the base of ball cap is inlayed a hardness height and abrasion resistant bulb bowl.It is big that ball head connecting rod and bulb bowl are that sphere contacts area of thrust surface, intensity height, reliable lock.When opening folding joint, ball head connecting rod separates with ball cap, can not form the triangle connecting rod, thereby can not cause injury and collision deformation to the people.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
