[0034] Example

[0035] This embodiment is intended to promote the solution of the traditional solution of fixing the T-handle with a seat tube clamp, which still has the risk of the T of the balance bike loosening during use. For this reason, this embodiment proposes a stepless adjustment device for the T-handle, through which a clamping member 11 with evenly distributed clamping teeth 111 cooperates with a locking member 3, and when connected, the locking member 3 can be correspondingly clamped into the clamping teeth 111 of the clamping member 11 to form a limit on the T-handle connecting member 1, so that the T-handle of the balance bike is not easy to loosen or slide during use, and the locking member 3 can be unlocked to break away from the limit of the clamping teeth 111, so that the T-handle can achieve stepless height adjustment, and can also achieve quick disassembly and assembly of the T-handle.

[0036] Reference Figure 1 and 5As shown, a T-handle stepless adjustment device includes: a T-handle connecting member 1, the T-handle connecting member 1 is provided with a locking member 11, and the locking member 11 has evenly distributed locking teeth 111; a front fork connecting component 2, and the front fork connecting component 2 is movably provided with a locking member 3; the T-handle connecting member 1 is inserted into the front fork connecting component 2, and the locking member 3 can be correspondingly locked into the locking teeth 111 of the locking member 11.

[0037] Reference Figure 2 and 3 As shown, in this embodiment, specifically, the front fork connecting assembly 2 includes:

[0038] The front fork stem 21 has an active window 211 at its end. The inner diameter of the front fork stem 21 matches the diameter of the T-bar connector 1 so that the T-bar connector 1 can be correspondingly inserted into the front fork stem 21 .

[0039] The front fork locking ring 22 is detachably connected to the end of the front fork vertical tube 21; the inner ring of the front fork locking ring 22 is adapted to the diameter of the front fork vertical tube 21, so that the front fork locking ring 22 can be sleeved on the outer ring of the end of the front fork vertical tube 21, and an adjustment window 221 adapted to the locking member 3 is provided on one side of the front fork locking ring 22, and the position of the adjustment window 221 corresponds to the movable window 211, and one end of the locking member 3 is rotatably connected to one end of the adjustment window 221, and a buckle portion 31 adapted to the latch tooth 111 is provided on the inner side of the locking member 3 near the rotating end, and the locking member 3 is rotated to snap into the adjustment window 221, so that the buckle portion 31 is correspondingly snapped into the latch tooth 111.

[0040] Reference Figure 4 As shown, in this embodiment, specifically, a T-slot 12 is provided on one side of the T-handle connector 1, and the positioning member 11 is adapted to the T-slot 12, and the positioning member 11 and the T-slot 12 are detachably connected; the latch teeth 111 are protrudingly provided on the end faces of both sides of the T-slot 12. It should be supplemented that the end faces of the latch teeth 111 are arc-shaped, and the diameter of the arc is adapted to the diameter of the T-handle connector 1, so that the latch teeth 111 can be inserted into the front fork vertical tube 21 together with the T-handle connector 1, and at the same time, the locking member 3 is rotated to fit the adjustment window 221, and the latch portion 31 of the locking member 3 can also be correspondingly inserted between the latch teeth 111; in some embodiments, in order to ensure the stable limiting of the T-handle connector 1, the locking member 3 is provided with a plurality of latch portions 31 adapted to the spacing of the latch teeth 111.

[0041] Reference Figure 2 and 4As shown, in this embodiment, specifically, a limiting protrusion 212 is provided inside the front fork stem 21, and a limiting groove 13 matched with the limiting protrusion 212 is provided on the outer side of the T-bar connector 1. When the T-bar connector 1 is inserted into the front fork stem 21, the limiting protrusion 212 can be correspondingly inserted into the limiting groove 13 to limit the relative rotation of the T-bar connector 1 and the front fork stem 21.

[0042] Reference Figure 3 As shown, in this embodiment, specifically, a buckle inner concave portion 32 is provided on the side of the lock member 3 away from the rotating end, and a buckle protrusion 2211 is provided on the adjustment window 221 to match the buckle inner concave portion 32. When the positioning member 11 is rotated and snapped into the adjustment window 221, the buckle protrusion 2211 can be correspondingly snapped into the buckle inner concave portion 32. The purpose of providing the buckle inner concave portion 32 and the buckle protrusion 2211 is to prevent the positioning member 11 from automatically rotating in a vibrating state during the use of the balancing vehicle, so that the buckle portion 31 of the lock member 3 is separated from the snap teeth 111, causing the T-handle connector 1 to fall off and cause danger.

[0043] In some embodiments, a return spring is installed at the rotational connection between the locking member 11 and the adjustment window 221, and the elastic force of the return spring keeps the locking portion 31 of the locking member 3 locked in the locking teeth 111. The user can overcome the elastic force of the spring by pulling, rotate the locking member 3, and disengage the locking portion 31 of the locking member 3 from the locking teeth 111 to release the limiting state. When the T-bar connector 1 is adjusted to a suitable height, the user lets go, and the elastic force of the return spring resets the locking member 3, and the locking portion 31 is correspondingly locked in the locking teeth 111.

[0044] Reference Figure 3 As shown, in this embodiment, specifically, the locking member 11 is in an arc shape, so that when the locking member 11 is locked into the adjustment window 221, the outer ring of the front fork lock ring 22 maintains a complete circular end surface.

[0045] Reference Figure 5 and 6 As shown, in this embodiment, specifically, a T-handle 4 is further included, and the bottom of the T-handle 4 is detachably connected to the top of the T-handle connector 1 .

[0046] Reference Figure 5 and 6 As shown, in this embodiment, specifically, a body bracket 5 is further included, and a connecting sleeve at the front end of the body bracket 5 is arranged at the bottom of the front fork locking ring 22 .
