Technical Field
[0001] This utility model relates to the field of scooter technology, specifically to a scooter with a folding locking structure that can be carried by hand. Background Technology
[0002] A scooter is a short-distance transportation tool that relies on the user to push off the ground to move forward. With the development of technology, electric scooters have also been invented. The structure of a scooter includes a base for pedaling and a front fork connected to the base. The front wheel is connected to the bottom of the front fork, and a seat tube is located at the top of the fork, with a handlebar at the top. Traditionally, the seat tube and front fork are fixedly connected, but to reduce space, the connection between the seat tube and front fork is made to rotate and fold. While folding reduces space, the lack of a locking mechanism means that the folded portion will loosen, making it inconvenient to lift and move by hand. One must move it first and then fold it for storage. When lifted, it is in the folded state, but the overall size of the folded portion is also relatively large, making it inconvenient to carry by hand. Summary of the Invention

By using a locking block located in a limiting groove to restrict the movement of the assembly base and thus restrict the rotation of the upright tube, the scooter has a folding locking structure, thus preventing it from coming undone after folding. At this time, the upright tube can be carried by hand to move the scooter. Therefore, it solves the problems of folding and loosening and inconvenience of hand carrying caused by the lack of a locking structure.

[0037] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.
[0038] like Figures 1-9 As shown, a scooter with a folding locking structure and designed for hand-carrying includes a front fork 1 and a stem 2 rotatably mounted on the front fork 1. A limiting structure is provided between the stem 2 and the front fork 1 to restrict the rotation of the folded stem 2. The front fork 1 is connected to a frame 10, which is used to place the scooter's base plate and is provided with a rotatable limiting plate 4. A locking block 41 is provided on one side of the limiting plate 4. The limiting structure includes an assembly base 3, which is mounted on the stem 2 and moves with the rotation of the stem 2. A limiting groove 32 is provided on one side of the assembly base 3.
[0039] Therefore, in actual use, the movement of the assembly base 3 is restricted by the locking block 41 located in the limiting groove 32, thereby restricting the rotation of the upright tube 2 after folding. That is, it has a folding locking structure, thereby avoiding the situation that it will loosen after folding. At this time, the upright tube 2 can be carried by hand to move the scooter.
[0040] Secondly, the structure of the limiting plate 4 is as follows: First, a mounting seat 20 is provided on the frame 10, and the mounting seat 20 and the limiting plate 4 are connected by a pivot 42, and an elastic element 43 is provided between the mounting seat 20 and the limiting plate 4.
[0041] Therefore, in actual use, the rotational connection is achieved by setting the three rotating shafts 42, and the limit plate 4 is easily reset by setting the elastic element 43.
[0042] like Figures 1-9As shown, the structure between the front fork 1 and the seat tube 2 is as follows: First, the front fork 1 includes a connecting part 11, and a connecting tube 12 is provided on the top of the connecting part 11. Mounting parts 13 are provided at both ends of the connecting part 11, and the bottom of the mounting part 13 is connected to the end of the front wheel axle.
[0043] Furthermore, the riser 2 includes two mounting pipes 21, which are connected by an assembly pipe 22. An assembly seat 3 is provided between the two mounting pipes 21. The bottom of the mounting pipe 21 is rotatably mounted on the top of the mounting part 13. The connecting pipe 12 is located in the limiting groove 32. A limiting component is provided between the connecting pipe 12 and the limiting groove 32. The limiting component is used to limit the detachment of the connecting pipe 12, thereby limiting the rotation of the folded riser 2.
[0044] Therefore, in actual use, by releasing the limiting component and rotating the riser 2, the riser 2 is folded while the limiting groove 32 and the connecting pipe 12 are separated. Thus, by rotating the fork 1 and the riser 2 in conjunction with the limiting component, folding is achieved and the riser is limited when not folded, thereby ensuring that it will not fold during use. At the same time, the bottom of the mounting pipe 21 is rotatably mounted on the top of the mounting part 13, meaning that the riser 2 is directly connected to the mounting part 13 and drives the movement of the shaft end. Compared with the prior art, the force applied by this invention is smaller and the rotation is more stable.
[0045] There are two assembly pipes 22, and a support pipe 23 is provided between the two assembly pipes 22 to ensure the stability of the riser 2 itself.
[0046] Meanwhile, the structure of the limiting component is as follows: First, the limiting component includes a handle 5 and a pressure block 6, and a groove 31 communicating with the limiting groove 32 is provided on one side of the assembly base 3, and a rotatable handle 5 and pressure block 6 are provided in the groove 31.
[0047] Furthermore, the handle 5 is connected to the pressure block 6 and drives the pressure block 6 to rotate. The pressure block 6 is located on one side of the connecting pipe 12, and a pin 7 for limiting rotation is provided between the handle 5 and the assembly base 3 or / and between the pressure block 6 and the assembly base 3.
[0048] Therefore, in actual use, the rotation of the handle 5 and / or the pressure block 6 is restricted by the limiting component, so that the top of the connecting pipe 12 is located in the limiting groove 32 and cannot be disengaged, that is, the riser 2 cannot be rotated. By releasing the limiting of the pin 7, the handle 5 and the pressure block 6 can be rotated. At this time, the handle 5 and the pressure block 6 no longer restrict the connecting pipe 12, so the riser 2 can be rotated, thereby driving the top of the connecting pipe 12 to disengage from the limiting groove 32.
[0049] The structure of the pin 7 varies. It can be that the handle 5 has a limit hole 51, and the pin 7 includes a connecting rod 71 and a rotating rod 72, and the connecting rod 71 is connected to the assembly base 3.
[0050] Meanwhile, the rotating rod 72 includes a limiting part 721 and a rod 722 located at the bottom of the limiting part 721. The bottom of the rod 722 passes through the connecting rod 71 and protrudes. The limiting part 721 provides a limiting block 723 on the outside of the rod 722. The connecting rod 71 has a slot 711 at the top.
[0051] Therefore, in actual use, the limiting block 723 is located in the slot 711 and the bottom of the rod 722 is located in the limiting hole 51, thereby restricting the rotation of the handle 5. By moving and rotating the rotating rod 72, the limiting block 723 is separated from the slot 711 and the limiting block 723 abuts against the top of the connecting rod 71, thereby separating the rod 722 from the limiting hole 51 and allowing the handle 5 to rotate.
[0052] Furthermore, the assembly base 3 has a hole 36, through which the connecting rod 71 passes and is threadedly connected to the hole 36.
[0053] Secondly, the limiting component can also be that the assembly base 3 has a snap-fit groove 33, and the pressure block 6 has a limiting hole 61. The pin 7 includes a moving rod 73 and a cap 74. The cap 74 is connected to the moving rod 73 and drives the moving rod 73 to move and rotate. Moreover, a protrusion 741 is provided on one side of the cap 74.
[0054] Therefore, in actual use, the bottom of the moving rod 73 is inserted into the assembly base 3 and located in the second limiting hole 61, thereby restricting the rotation of the pressure block 6. By moving and rotating the cap 74, the moving rod 73 is moved and rotated, and the protrusion 741 is located in the snap-fit groove 33, thereby separating the moving rod 73 from the second limiting hole 61 and allowing the pressure block 6 to rotate.
[0055] Furthermore, the assembly base 3 has a second hole 37, through which the moving rod 73 passes, and a spring can be provided between the moving rod 73 and the assembly base 3 to facilitate the reset of the moving rod 81.
[0056] like Figure 6 As shown, the pressure block 6 has a movable clamping block 9 on the side near the connecting pipe 12, and an adjusting rod is threadedly connected to the other side of the pressure block 6. One end of the adjusting rod passes through the pressure block 6 and abuts against the clamping block 9, while the other end of the adjusting rod is located outside the pressure block 6.
[0057] Therefore, in actual use, by rotating the adjusting rod, the pressure block 6 is pushed towards the connecting tube 12 and made to fit against the connecting tube 12. Thus, when not folded, the stability of the connection and the limiting position is ensured.
[0058] Furthermore, the moving structure between the pressure block 6 and the clamping block 9 is as follows: First, the pressure block 6 has a groove 62 on the side near the connecting pipe 12, and the clamping block 9 has a connecting plate 91 on the side near the pressure block 6. The connecting plate 91 has an elongated hole 911, and the connecting plate 91 is located inside the groove 62. A fastener is inserted into the groove 62 and located inside the elongated hole 911, and the fastener is connected to the pressure block 6. The fastener is a screw.
[0059] Therefore, in actual use, the fastener is connected to the pressure block 6 and located in the elongated hole 911, thereby preventing the pressure block 9 from detaching from the pressure block 6. When the adjusting rod moves the pressure block 6, the connecting plate 91 moves in the groove 62, and the fastener moves relative to the elongated hole 911 in the elongated hole 911.
[0060] like Figures 5-9 As shown, the rotating structure of the handle 5 and the pressure block 6 is as follows: First, a groove 52 is provided at one end of the handle 5, and this end of the handle 5 is rotatably connected to the assembly base 3, that is, two screws are used to achieve the rotatable connection between the assembly base 3 and the handle 5. The use of screws for connection allows for rotation, which is existing technology, and because the tightness and gap of the screws can be adjusted, there is room for rotation.
[0061] Moreover, one end of the pressure block 6 is located in the groove 52, and this end of the pressure block 6 is connected to the handle 5 through the pivot 63, that is, the pivot 63 is used to realize the rotational connection between the pressure block 6 and the handle 5.
[0062] like Figure 5 and Figure 6 As shown, the installation structure of the assembly base 3 is as follows: First, the assembly base 3 includes a main body 34 and two fixed seats 35. The main body 34 and the fixed seats 35 are provided with arc-shaped grooves corresponding to the mounting tube 21. The main body 34 and the fixed seats 35 are located on both sides of the mounting tube 21. Fasteners pass through the fixed seats 35 and are connected to the main body 34, thereby setting the assembly base 3 on the mounting tube 21.
[0063] At the same time, such as Figures 2-5 As shown, the structure between the mounting part 13 and the mounting tube 21 is as follows: First, a mounting plate 131 is provided on the top of the mounting part 13, and a mounting groove 211 is opened at the bottom of the mounting tube 21 corresponding to the mounting plate 131. A rotating shaft passes through the bottom of the mounting tube 21 and the mounting plate 131 to realize the connection between the mounting part 13 and the mounting tube 21.
[0064] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. However, this utility model is not limited to the above embodiments; therefore, various changes and modifications can be made without departing from the principles and scope of this utility model, and all such changes and modifications fall within the scope of the claimed utility model.
