[0016] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0017] The utility model provides a locking structure for a foldable scooter, which is used for a foldable scooter product.

[0018] Please refer to Figures 1 to 3 As shown, the locking structure for a folding scooter of the utility model comprises a fixing rod 1 and a folding rod 2, one end of the fixing rod 1 is hinged to one end of the folding rod 2, a side wall of one end of the fixing rod 1 is provided with a threaded locking portion 11, and a side wall of one end of the folding rod 2 is provided with a threaded mounting portion 21;

[0019] It also includes a locking sleeve 3, which is sleeved on the folding rod 2, and the locking sleeve 3 is connected to the thread locking portion 11 and the thread installation portion 21 respectively.

[0020] From the above description, it can be seen that the beneficial effect of the utility model is that: the locking structure for the folding scooter is provided with a threaded connection structure on the circumferential surface of the fixed rod 1 and the folding rod 2, and the locking sleeve 3 is screwed with the threaded connection structure through a threaded connection. When the fixed rod 1 and the folding rod 2 are relatively folded, the locking sleeve 3 is screwed on the threaded mounting portion 21 of the folding rod 2. After the fixed rod 1 and the folding rod 2 are relatively opened, the locking sleeve 3 is simultaneously connected to the threaded locking portion 11 and the threaded mounting portion 21, so as to achieve relative fixation of the fixed rod 1 and the folding rod 2. Compared with the traditional folding locking structure, the locking structure for the folding scooter provided by the utility model reduces the number of components, simplifies the operation steps, and saves costs while ensuring the reliability of the structure.

[0021] In an optional embodiment, it also includes a positioning sleeve 4, which is sleeved on the folding rod 2, and the positioning sleeve 4 is rotatably connected to the locking sleeve 3. The folding rod 2 is provided with a strip hole 22, and the positioning sleeve 4 is provided with a positioning column 41 that is slidably connected to the strip hole 22.

[0022] It can be seen from the above description that the positioning sleeve 4 is slidably matched with the strip hole 22 of the folding rod 2 through the positioning column 41 to achieve guidance and limitation, thereby improving the structural stability.

[0023] In an optional embodiment, both the thread locking portion 11 and the threaded mounting portion 21 are provided with a locking hole 12 , and the locking sleeve 3 is provided with a positioning hole 31 locked with the locking hole 12 .

[0024] It can be seen from the above description that the locking sleeve 3 and the fixing rod 1 and / or the folding rod 2 are locked together by the locking hole 12 and the positioning hole 31 .

[0025] In an optional embodiment, the two positioning holes 31 on the locking sleeve 3 are respectively locked with the locking holes 12 on the threaded locking portion 11 and the threaded mounting portion 21 .

[0026] In an optional embodiment, an annular limiting boss 13 for supporting the locking sleeve 3 is provided on the fixing rod 1 .

[0027] It can be seen from the above description that the annular limiting boss 13 plays a role of supporting and limiting the locking sleeve 3 .

[0028] Please refer to Figures 1 to 3 As shown, the first embodiment of the utility model is: a locking structure for a folding scooter, comprising a fixed rod 1 and a folding rod 2, one end of the fixed rod 1 is hinged to one end of the folding rod 2, a side wall of one end of the fixed rod 1 is provided with a threaded locking portion 11, and a side wall of one end of the folding rod 2 is provided with a threaded mounting portion 21;

[0029] It also includes a locking sleeve 3, which is sleeved on the folding rod 2, and the locking sleeve 3 is connected to the thread locking portion 11 and the thread installation portion 21 respectively.

[0030] It also includes a positioning sleeve 4, which is sleeved on the folding rod 2, and the positioning sleeve 4 is rotatably connected to the locking sleeve 3. The folding rod 2 is provided with a strip hole 22, and the positioning sleeve 4 is provided with a positioning column 41 that is slidably connected to the strip hole 22. The threaded locking portion 11 and the threaded mounting portion 21 are both provided with a locking hole 12, and the locking sleeve 3 is provided with a positioning hole 31 that is locked with the locking hole 12. The two positioning holes 31 on the locking sleeve 3 are respectively locked with the locking holes 12 on the threaded locking portion 11 and the threaded mounting portion 21. The fixing rod 1 is provided with an annular limiting boss 13 for supporting the locking sleeve 3.

[0031] In summary, the locking structure for a folding scooter of the utility model has a threaded connection structure on the circumferential surface of the fixed rod and the folding rod, and the locking sleeve is screwed with the threaded connection structure through a threaded connection. When the fixed rod and the folding rod are relatively folded, the locking sleeve is screwed on the threaded mounting portion of the folding rod. After the fixed rod and the folding rod are relatively opened, the locking sleeve is simultaneously connected to the threaded locking portion and the threaded mounting portion to achieve relative fixation of the fixed rod and the folding rod. Compared with the traditional folding locking structure, the locking structure for a folding scooter provided by the utility model reduces the number of components, simplifies the operation steps, and saves costs while ensuring structural reliability.
