DETAILED DESCRIPTION

[0036] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the accompanying drawings, in which typical embodiments of the present invention are shown.

[0037] Embodiment 1:

[0038] like Figure 1-Figure 5As shown, the utility model is an anti-theft folding scooter for children, comprising a scooter body 1, a front wheel 2, a rear wheel 3 and a connecting shaft 4, a rotating sleeve 5 is sleeved on the connecting shaft 4, an adjustable rod 6 is arranged on the rotating sleeve 5, a handle 7 is arranged on the top of the adjustable rod 6, a locking mechanism 8 is arranged on the connecting shaft 4 and the rotating sleeve 5; the locking mechanism 8 comprises a clamping strip 803, a U-shaped rod 810, an I-shaped rod 811 and a vertical rod 813, a first clamping groove 801 is provided on the connecting shaft 4, a second clamping groove 802 is provided on the rotating sleeve 5, a limiting hole 805 and a circular hole 806 are provided on the clamping strip 803, a limiting block 807 is arranged on the top of the U-shaped rod 810, and a rotating shaft is arranged inside the U-shaped rod 810. 808, a sliding sleeve 812 is provided at the bottom of the vertical rod 813, a through hole 814 is opened at the bottom inside the front wheel 2, the scooter body 1, the front wheel 2, the rear wheel 3 and the connecting shaft 4, and cooperate with the rotating sleeve 5 and the adjustable rod 6. The utility model provides a product that can be flexibly folded and stored, which increases the applicability and convenience of the product. The design of the locking mechanism 8, especially the combination of the card strip 803, the U-shaped rod 810, the I-shaped rod 811 and the vertical rod 813, provides an effective anti-theft mechanism for the scooter. When the scooter body 1 is stored and idle, the adjustable rod 6 is kept in a retracted state and the front wheel 2 is kept in a locked state, which improves the safety of the scooter when idle and reduces the risk of theft.

[0039] like Figure 1 , Figure 2 , Figure 3 As shown, the rotating sleeve 5 is rotatably connected to the connecting shaft 4, the front wheel 2 is rotatably connected to the connecting shaft 4, the rotating sleeve 5 is fixedly connected to the adjustable rod 6, and the rotational connection between the front wheel 2 and the connecting shaft 4 ensures the flexibility and stability of the scooter during use, so that children can slide smoothly. The setting of the rotating sleeve 5 enables the adjustable rod 6 to be folded and stowed or set vertically on the scooter body 1 according to the needs of use, so as to adapt to various scenarios during use.

[0040] like Figure 3 , Figure 5 As shown, the card strip 803 is a rectangular strip structure, and the card strip 803 is engaged and slid with the first card slot 801 and the second card slot 802. The rectangular strip structure design of the card strip 803 is convenient for engaging and sliding with the first card slot 801 and the second card slot 802, which simplifies the folding and unfolding operation process and ensures that the adjustable rod 6 always remains in a stable state in both states, so that children and parents can quickly store and use the scooter.

[0041] like Figure 3 , Figure 5As shown, the limit block 807 is adapted to the limit hole 805, the limit hole 805 is connected to the circular hole 806, the diameter of the circular hole 806 is larger than the length of the longest end of the limit block 807, and the limit block 807 and the limit hole 805 have a high degree of adaptability, so that the process of the limit block 807 entering the limit hole 805 can proceed smoothly, the circular hole 806 and the limit hole 805 remain connected, and the special setting of their diameters makes it possible for the limit block 807 to pass through the limit hole 805 and enter the circular hole 806. After that, the angle can be adjusted by rotation to ensure that the position of the limit block 807 is fixed.

[0042] like Figure 3 , Figure 5 As shown, the U-shaped rod 810 is fixedly connected to the I-shaped rod 811, the sliding sleeve 812 is engaged and slidably engaged with the I-shaped rod 811, and the vertical rod 813 is fixedly connected to the sliding sleeve 812. The U-shaped rod 810 and the limit block 807 on the top thereof can be used to assist in fixing the I-shaped rod 811, the sliding sleeve 812 and the vertical rod 813 in a vertical position. The special connection between the sliding sleeve 812 and the I-shaped rod 811 can assist the vertical rod 813 to move away from the through hole 814 when the locking mechanism 8 fixes the vertical adjustable rod 6 in use, thereby ensuring that the front wheel 2 can move normally, and when the scooter body 1 is in an idle storage state, the auxiliary vertical rod 813 is inserted into the through hole 814 to lock the front wheel 2.

[0043] like Figure 2 , Figure 3 As shown, two vertical rods 813 are provided, and the two vertical rods 813 are symmetrically arranged. The vertical rods 813 are adapted to the through holes 814. The symmetrical arrangement of the two vertical rods 813 provides balanced support for the folding and locking of the scooter, ensuring that the two front wheels 2 of the scooter remain locked at the same time when the scooter is in the folded state. The adaptive design of the vertical rods 813 and the through holes 814 provides precise positioning for the locking of the front wheels 2, ensuring that the vertical rods 813 can be smoothly inserted into the through holes 814 when they move upward with the U-shaped rod 810 and the I-shaped rod 811.

[0044] like Figure 2 , Figure 4 As shown, two first card slots 801 are provided, and the two first card slots 801 are distributed at 90 degrees along the circumference of the connecting shaft 4. The two first card slots 801 distributed at 90 degrees can make the adjustable rod 6 maintain the corresponding state by using the locking mechanism 8 after being folded or during use, so as to prevent the adjustable rod 6 from being arbitrarily shifted after being folded or by the user, affecting the safety of use or the stability when stored.

[0045] Embodiment 2:

[0046] like Figure 3 , Figure 5As shown, on the basis of the first embodiment, the utility model provides a technical solution: a special-shaped hole 809 is opened at the bottom of the rotating shaft 808, the inner diameter of the special-shaped hole 809 is hexagonal, and the outer diameter of the special-shaped hole 809 is circular. The design of the special-shaped hole 809 at the bottom of the rotating shaft 808, especially the combination of the hexagonal inner diameter and the circular outer diameter, requires the use of special tools when using the locking mechanism 8, which increases the threshold for use, and at the same time provides a unique locking method for using a special hexagonal wrench, increases the difficulty of unlocking, and improves the anti-theft performance of the scooter.

[0047] like Figure 2 , Figure 3 As shown, a pull ring 804 is provided on one side of the card strip 803, and the pull ring 804 is a semi-annular structure. The design of the pull ring 804 on one side of the card strip 803, especially the semi-annular structure, provides a convenient gripping point for the user when operating the card strip 803, simplifies the operation process of the locking mechanism 8, and improves the convenience of use. The semi-annular structure of the pull ring 804 makes the part that the user's hand contacts during use smoother and is not easy to cause hand injuries.

[0048] like Figure 3 , Figure 5 As shown, the U-shaped rod 810 is rotatably connected to the rotating shaft 808, and the rotating shaft 808 is fixedly connected to the limit block 807. When a special hexagonal wrench is inserted into the special-shaped hole 809, the rotating shaft 808 can be driven to rotate inside the U-shaped rod 810, thereby driving the limit block 807 fixedly connected to the rotating shaft 808 to rotate, and further realizing the use of the limit hole 805 and the circular hole 806 to fix or release the limit block 807 and the U-shaped rod 810, the I-shaped rod 811 and other components at the bottom thereof.

[0049] During implementation, first, when the scooter body 1 needs to be used, the card strip 803 is pushed into the first card slot 801 and the second card slot 802, and the card strip 803 is moved to the limit on one side of the first card slot 801, and the two sliding sleeves 812 are pulled to slide toward the middle of the I-shaped rod 811, driving the vertical rod 813 to move synchronously, so that it is away from the through hole 814, and pushing the U-shaped rod 810 and the limit block 807 to move upward, so that the limit block 807 is aligned with the limit hole 805, and the U-shaped rod 810 and the limit block 807 are pushed up to the limit. The limit block 807 is located in the circular hole 806. A special hexagonal wrench that is fully compatible with the special-shaped hole 809 is inserted into the special-shaped hole 809, and the rotating shaft 808 is rotated to drive the limit block 807 to rotate in the circular hole 806 until the limit block 807 is no longer parallel to the limit hole 805. At this time, the adjustable rod 6 is perpendicular to the scooter body 1 and remains stable in the vertical state. The front wheel 2 is in a flexible state. After the child raises the adjustable rod 6 to a state that matches his or her height, he or she can use the scooter body 1 normally for exercise;

[0050] When the scooter body 1 is used up and needs to be stored and locked, an Allen wrench is inserted into the special-shaped hole 809, and the rotating shaft 808 is rotated in the opposite direction, thereby driving the limit block 807 to rotate in the opposite direction until it is parallel to the limit hole 805 again, and the U-shaped rod 810 is pulled downward to drag the limit block 807 out of the circular hole 806 and the limit hole 805, and the pull ring 804 is pulled to pull the card strip 803 to the other side of the first card slot 801. At this time, the rotating sleeve 5 can rotate smoothly along the connecting shaft 4, driving the adjustable rod 6 to adjust to a state parallel to the scooter body 1, completing the folding of the children's scooter. After the other first card slot 801 and the second card slot 802 are opposite to each other again, the card strip 803 is pulled again. Push it into the first slot 801 and the second slot 802 until the strip 803 moves to the limit of the first slot 801, and pull the two sliding sleeves 812 to slide to the limit outside the I-shaped rod 811. At this time, the vertical rod 813 is opposite to the through hole 814, and then repeat the process of pushing upward and using the Allen wrench to rotate the limit block 807 to fix the U-shaped rod 810. During this process, the vertical rod 813 moves upward with the U-shaped rod 810 and is inserted into the through hole 814. At this time, the adjustable rod 6 remains in a folded and stored state, and the front wheel 2 is in a locked state. When a special Allen wrench is not used, the folded and stored adjustable rod 6 cannot be opened and the front wheel 2 cannot move, thereby achieving the effect of improving safety when stored idle.

[0051] The advantages of this technical solution in practical applications include but are not limited to the following:

[0052] 1. The setting of the locking mechanism 8 can ensure that the adjustable rod 6 remains stable and convenient for children to hold when the scooter body 1 is in use, and the front wheel 2 can move forward smoothly. When folding and storing, the adjustable rod 6 remains in the stored state and the front wheel 2 is in the locked state, ensuring that the safety of the scooter body 1 is improved to a certain extent when it is idle;

[0053] 2. The setting of the special-shaped hole 809 requires the use of a specially prepared hexagonal wrench to activate the entire locking mechanism 8, thereby raising the threshold for unlocking the adjustable rod 6 and the front wheel 2, thereby further improving safety.

[0054] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
