BEST MODE FOR CARRYING OUT THE INVENTION

BEST MODE FOR CARRYING OUT THE INVENTION

[0016] As shown in the figure, a locking and unlocking device for folding a joint, a gear 3 is disposed between the folding shaft 1 and the folding sleeve 2, and the folding sleeve 2 is provided with a hole for passing the locking pin 5 with the spring 4 The sleeve is inserted between the teeth of the gear 3. The locking pin 5 includes a circular recess 16 , and the locking pin 5 is sleeved with a rotatable annular sleeve 6 , and the annular sleeve is provided with an elastic convex corresponding to the concave hole. The ball 7, the locking pin 5 is provided with a rotatable annular sleeve 6, the folding shaft 1 is arranged on the front folding member 15, the folding sleeve 2 is connected to the rear folding member 14, the locking pin 5 comprises a long rod portion 8 and an insertion The end portion 9 is provided with an annular sleeve 6 at the long rod portion 8. The long rod portion 8 is correspondingly provided with an elastic convex ball 7, the spring 4 is provided with a bolt for adjusting the elasticity, and the locking pin 5 is inserted into the hollow bolt 13 at the end. The bolt 13 is placed on top of the spring, and the lock pin 5 is spaced from the bottom of the hole of the hollow bolt 13 by a distance. The distance between the lock pin 5 and the bottom of the hole limits the spring 4 to adjust the elastic stroke. The annular sleeve 6 is provided with a handle 10, and the neck of the handle 10 is provided with a damping seal _U , the control end 12 of which extends beyond the damping seal 11. The elastic convex ball includes a rigid spherical surface and a spring. When pressed by an external force, the spring is tightened, and the surface of the spherical body is forced to be recovered.

[0017] In the unfolded state, the lock pin 5 is inserted between the teeth of the gear 3, and the elastic convex ball 7 of the annular sleeve 6 is ejected into the circular recess 16 of the lock pin 5, and the lock pin 5 cannot move backward, and the rear folding member 14 Locked together with the front folding member 15, the driver can ride on the vehicle. When the storage raft is required to be folded, the operating end 12 is rotated, and the annular sleeve 6 fixedly connected with the operating end 12 is rotated, and the elastic convex ball 7 provided on the annular sleeve 6 is rotated accordingly, and the force applied to the operating end 12 is required. The resistance of the circular concave hole 16 to the elastic convex ball 7 is increased, and the elastic concave ball 7 is pressed to deform the inner spring to slide out from the circular concave hole 16, and the locking ring sleeve 6 unlocks the locking pin 5, and the folding sleeve is folded. 2 can be rotated relative to the folding shaft 1, after the folding, the folding member 14 is folded, the gear rotating force overcomes the elastic force of the spring provided by the locking pin 5, and the locking pin 5 sequentially slides over the respective teeth on the gear 3, when folded in place吋, the steering end 12 is rotated again, the elastic convex ball 7 is rotated to the original position and is inserted into the circular recessed hole 16, the locking pin insertion end cannot be retracted, and the gear 3 is inserted again between the teeth, and the rear folding member 14 and the front folding member 15 are locked. Solid, can't fight.

[0018] Starting from the folded state, the steering end 12 is rotated again to control the elastic convex ball 7 to be disengaged from the circular recessed hole 16, and then the rear folding member 14 and the front folding member 15 can be stretched and moved to the same position. The steering end 12 is rotated to change the position of the elastic convex ball ₇ to lock the rear folding member 14 and the front folding member 15.

[0019] The locking joint can be locked and unlocked, the structure is simple, the stacking is integrated, and the folding operation is performed in the position of the operating terminal 12 to realize the locking, and the operating terminal 12 is operated again to realize the locking, without separately setting The locking device has high structural strength and good locking stability, which greatly reduces the operation accessories and procedures, and has strong practicability. The spring is provided with a bolt for adjusting the tension. When the spring force of the tightening bolt 吋 spring is increased, the spring force of the loosening bolt 吋 spring is reduced, thereby controlling the resistance of the locking pin 5 to the gear 3 吋. The neck of the handle 10 is provided with a damping sealing cover 11 whose guiding end 12 extends beyond the damping sealing cover 11. The sealing cover can be dustproof, and can prevent the steering end 12 from swinging, and functions as a fixed operating end 12. The locking pin 5 is inserted into the hollow bolt 13 at the end, and the inner hole of the hollow bolt 13 functions to position the locking pin 5. The inner hole is reserved for the stroke without hindering the adjustment of the bolt, and the design is ingenious.

[0020] The invention has simple structure, novel design, low cost and high efficiency, and is suitable for mass production and promotion.
