The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

As shown in fig. 1 and 2, the preferred embodiment provides a folding handle riser comprising a riser upper seat 1, a riser lower seat 2, and a handle assembly.

One side of the upper stand pipe seat 1 is rotatably connected with the lower stand pipe seat 2 through a pin shaft, the other side of the upper stand pipe seat 1 is provided with a boss 3, and the boss 3 is provided with a convex tooth 4.

The handle assembly comprises a handle block 5, one end of the handle block 5 is rotatably connected with the lower stand pipe seat 2 through a pin shaft, the other end of the handle block 5 is connected with the boss 3 through a connecting rod 6, the stand pipe upper seat 1 is turned and folded according to the principle that a quadrangle has mobility, and the length of the connecting rod 6 is adjustable, so that the folding angle of the stand pipe upper seat 1 is controlled.

The handle block 5 is provided with a hook 7, the hook 7 is provided with a first hook tooth 8 and a second hook tooth 9, the first hook tooth 8 and the second hook tooth 9 are respectively formed on two sides of the hook 7, the extension amount of the first hook tooth 8 is larger than that of the second hook tooth 9, and the boss 3 is correspondingly provided with two convex teeth 4.

When the riser upper seat 1 is located at a position coinciding with the axis of the riser lower seat 2, the first hook teeth 8 hook the convex teeth 4, and the riser upper seat 1 is in an automatic locking state, as shown in fig. 3.

When the handle block 5 is located in a position parallel to the riser upper seat 1, the second hook tooth 9 hooks the convex tooth 4, and the riser upper seat 1 is in a manual locking state, as shown in fig. 4.

When the first and

second hooks

8, 9 are disengaged from the convex teeth 4, the riser upper seat 1 is in an unlocked state, as shown in fig. 5.

The specific locking structure is that the hook 7 is positioned on one side of the handle block 5 facing the riser upper seat 1, a driving block 10 is arranged on one side of the handle block 5 facing away from the riser upper seat 1, a stroke groove 11 is formed in the handle block 5, the driving block 10 is slidably arranged in the stroke groove 11 and penetrates through the stroke groove 11 to be fixedly connected with the handle block 5, and the driving block 10 is driven to enable the first hook tooth 8 or the second hook tooth 9 to be hooked with or separated from the convex tooth 4, so that the riser upper seat 1 is switched from a locking state or a locking state to an unlocking state.

Further, the first spring 12 is interposed in the stroke groove 11, and the first spring 12 acts on the driving block 10 and gives a thrust force to the first hook 8 or the second hook 9 toward the teeth 4, thereby maintaining the hooked state with the teeth 4.

The second spring 13 is sleeved on the connecting pin shaft of the lower stand pipe seat 2 of the handle block 5, and the second spring 13 provides thrust for the handle block 5 to face the upper stand pipe seat 1, so that the first hook teeth 8 can be kept in a state of hooking the convex teeth 4, namely, under the condition that the handle block 5 is not normally pressed, when the upper stand pipe seat 1 is located at the position coinciding with the axis of the lower stand pipe seat 2, the upper stand pipe seat 1 is necessarily in an automatic locking state.

In addition, the lower end of the handle block 5 is connected with the lower stand pipe seat 2, and the upper end of the handle block 5 forms a convex edge 14 convenient for pressing and pulling.

When the folding seat is used and operated, in an upper locking state (automatic locking or manual locking), two actions are needed for unlocking, namely, the driving block 10 is pushed by overcoming the elastic force of the first spring 12, so that the first hook tooth 8 and the second hook tooth 9 are separated from the convex tooth 4, and the handle block 5 is pulled open by overcoming the elastic force of the second spring 13, so that the upper seat 1 of the vertical pipe can freely rotate for a certain angle, and folding is realized.

When locking is needed, the vertical pipe upper seat 1 is pushed to the position coinciding with the axis of the vertical pipe lower seat 2, the first hook tooth 8 on the handle block 5 under the normal state hooks the convex tooth 4 on the boss 3, the vertical pipe upper seat 1 is locked, and the vertical pipe upper seat is allowed to swing in a small range at the moment but cannot be folded; further, the handle block 5 is pressed to be parallel to the riser upper seat 1, the second hook teeth 9 on the handle block 5 hook the convex teeth 4 on the boss 3, and the riser upper seat 1 is locked, so that double locking is realized.

In conclusion, the folding mode of the upper seat of the vertical pipe is designed by applying the principle that the quadrangle has the mobility to the vertical pipe, the functions of automatically locking, manually locking and unlocking the upper seat of the vertical pipe are realized through the hook with the special shape, the reliability of the folding device is improved, the normal riding use and the folding function are ensured, the structure is ingenious, and the use is convenient.

The above embodiments have been merely illustrative of the basic principles and features of the present invention, and the present invention is not limited by the above embodiments, and does not depart from the spirit and scope of the present invention.
