Abstract
Description
Technical Field
[0001] This utility model relates to the field of scooter technology, specifically to a scooter folding device with double locking. Background Technology
[0002] Scooters are a two-wheeled mode of transportation with advantages such as portability and ease of assembly. They can be used as a trendy sports product for the new generation of teenagers, as well as a means of transportation for adults in big cities.
[0003] Some scooters currently have folding mechanisms that allow the stem to fold directly after the user presses a button. This can easily lead to the stem folding due to misoperation or accidents, posing a significant safety hazard. Summary of the Invention
[0004] A scooter folding mechanism with double locking includes: a stem, an upper seat, a lower seat, a handle, a first locking block, a second locking block, a push button, two locking blocks, a return spring, a clamping shaft, a first screw, a second screw, a third screw, a first pin, and a second pin. The riser is fitted onto the top of the upper seat, and a first screw is threaded through the wall of the riser and connected to the upper seat, so that the riser and the upper seat are fixed together. The upper seat extends with a front connector and a rear connector, and both the front connector and the rear connector are provided with through holes. The lower seat extends to have a front mating head and a rear mating head, both of which are provided with through holes; the rear mating head is embedded in the rear connector, and a second pin passes through the rear mating head and the rear connector, and the second pin is fixed with a first screw, so that the upper seat and the lower seat are rotatably connected together. The bottom of the handle is provided with a through hole; The two locking blocks are also provided with through holes, and the two locking blocks are embedded in the inner side of the bottom of the handle, with the through holes of the two corresponding to each other; the second screw passes through the handle, the two locking blocks, and the front connector, so that the handle is connected to the lower seat; There are two return springs, which are respectively locked on both sides of the two locking blocks; The first pin is located at the through hole of the front connector and is fixed with a third screw; the top of the second locking block abuts against the first pin. The handle is provided with a groove, the push button is located on one side of the handle and cooperates with the groove, and one end of the push button is provided with a threaded hole; The first and second locking blocks are located on the other side of the handle. The first and second locking blocks are provided with threaded holes. The first locking block, the second locking block, and the push button are connected in sequence by a first screw, so that the push button is connected to the handle and slides in the groove.
[0005] The beneficial effects of this utility model are as follows: This invention improves safety by incorporating a double-locking structure to prevent the folding mechanism from opening accidentally. Simply press down to open the double-locking structure and fold normally; operation is convenient and simple. Attached Figure Description
[0006] Figure 1 This is a front view of the present invention.
[0007] Figure 2 This is an exploded view of the components of this utility model. Detailed Implementation
[0008] Preferred embodiments of this utility model will be described in detail with reference to the accompanying drawings, which will facilitate the implementation of these embodiments by those skilled in the art. However, this utility model can be implemented in various different forms, and therefore is not limited to the embodiments described below. Furthermore, for clarity, components not connected to this utility model will be omitted from the drawings.
[0009] A scooter folding mechanism with double locking includes: a stem 1, an upper seat 2, a lower seat 3, a handle 4, a first locking block 5, a second locking block 6, a push button 7, a second locking block 8, a return spring 9, a clamping shaft 10, a first screw 11, a second screw 12, a third screw 13, a first pin 14, and a second pin 15. like Figure 2 As shown, the riser 1 is sleeved on the top of the upper seat 2, and the first screw 11 passes through the wall of the riser 1 and is threaded to the upper seat 2, so that the riser 1 and the upper seat 2 are fixed together. The upper seat 2 extends with a front connector 21 and a rear connector 22, and both the front connector 21 and the rear connector 22 are provided with through holes; The lower seat 3 extends to a front mating joint 31 and a rear mating seat 32. Both the front mating joint 31 and the rear mating seat 32 are provided with through holes. The rear mating seat 32 is embedded in the rear connector 22. The second pin 15 passes through the rear mating seat 32 and the rear connector 22, and is fixed by the first screw 11, so that the upper seat 2 and the lower seat 3 are rotatably connected together. The bottom of the handle 4 is provided with a through hole; The second locking block 8 is also provided with a through hole. The second locking block 8 is embedded in the bottom inner side of the handle 4, and the through holes of the two are in corresponding positions. The second screw 12 passes through the handle 4, the second locking block 8, and the front connector 31, so that the handle 4 is connected to the lower seat 3. The cooperation between the handle 4 and the lower seat 3 achieves a single locking. There are two return springs 9, which are respectively locked on both sides of the second locking block 8, and are used to generate a return force on the second locking block 8; The first pin 14 is located at the through hole of the front connector 21 and is fixed by the third screw 13; the top of the second locking block 8 abuts against the first pin 14. The handle 4 is provided with a groove, the push button 7 is located on one side of the handle 4 and cooperates with the groove, and one end of the push button 7 is provided with a threaded hole; The first locking block 5 and the second locking block 6 are located on the other side of the handle 4. The first locking block 5 and the second locking block 6 are provided with threaded holes. The first screw 11 is used to sequentially thread the first locking block 5, the second locking block 6 and the push button 7, so that the push button 7 is connected to the handle 4 and the push button 7 slides in the groove. Pressing the push button 7 causes the second locking block 6 to push the two locking blocks 8 to abut against the first pin 14, so as to achieve double locking.
[0010] In the description of this technical solution, it should be specifically noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" used herein should be interpreted broadly.
