Technical Field

[0001] This application relates to the technical field of fixing folding rods, and in particular to a folding locking device. Background Technology

[0002] With social development and the improvement of people's living standards, folding products such as folding bicycles, folding electric bikes, and folding scooters are constantly appearing in our lives, greatly improving our living standards. The folding mechanism plays a significant role in these folding products. Folding reduces the size of the product, making it easy to store after folding; therefore, the folding mechanism is an essential component of folding products.

[0003] Patent application CN201921816061.X discloses a self-locking and stable folding device, including an upper body, a lower body, a first locking block, a button, a second locking block, and a handle. The upper body and the lower body are hinged together, the handle is rotatably connected to the lower body, and the second locking block is fixedly connected to the upper body. The first locking block is connected to the button, and both the first locking block and the button are slidably connected to the handle. The first locking block is located on the side of the handle facing the upper body, and the button is located on the side of the handle. Moving the button controls the position of the first locking block on the handle, thereby controlling the first locking block and the second locking block to lock together. When the handle is engaged, the button needs to be moved to separate the first locking block and the second locking block. Since the button is on the side of the handle, it needs to be pushed with a finger. The area on the button that can bear force is small, and the space between the button and the handle for the finger to place is small. As a result, during the process of moving the button, due to the different sizes of human hands, the button may not be able to bear force, making it difficult or inconvenient to move the button with the finger.

[0029] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] This application provides a folding locking device that solves the problem of inconvenient button usage in related technologies.

[0031] Please see Figures 1 to 5 A folding locking device comprising:

[0032] Upper body 1, lower body 2, handle 3; upper body 1 is hinged to lower body 2, and handle 3 is hinged to lower body 2.

[0033] First locking block 4, second locking block 5, second locking block 5 is connected to the upper body 1, first locking block 4 is set on handle 3, first locking block 4 and second locking block 5 can be locked together;

[0034] Control component 6 includes slider 61 and extension platform 62. Slider 61 is slidably connected to handle 3, and extension platform 62 is connected to slider 61. One end of extension platform 62 extends away from handle 3.

[0035] In this embodiment, as Figure 1 As shown, the upper body 1 and the lower body 2 are hinged on one side by a pivot, and the other side of the lower body 2 is hinged to one end of the handle 3 by a connecting rod 13. The second torsion spring 12 continuously provides a force to the handle 3 to rotate upwards towards the upper body 1. The second locking block 5 is fixedly connected to the upper body 1 by bolts. An opening is provided on the handle 3, and the slider 61 passes through the opening and is connected to the first locking block 4. The position of the first locking block 4 on the handle 3 can be controlled by moving the position of the slider 61. When the upper body 1 and the lower body 2 are in contact, the slider 61 is first moved away from the hinge point of the handle 3, and then the handle 3 is rotated towards the upper body 1 until the handle 3 is closed. Finally, the slider 61 is moved so that the first locking block 4 falls down and engages with the second locking block 5, thus locking the upper body 1 and the lower body 2.

[0036] An extension platform 62 is fixedly connected to the slider 61. The area of ​​the extension platform 62 is larger than that of the slider 61, and the space between the extension platform 62 and the handle 3 is larger than that between the slider 61 and the handle 3. Therefore, using the extension platform 62 to control the movement of the slider 61 and the first locking block 4 is undoubtedly more applicable and more convenient.

[0037] Furthermore, in this embodiment, the handle 3 is provided with a lever 7 on the side away from the lower body 2. The lever 7 is arranged opposite to the extension platform 62. The handle 3 extends away from the lower body 2 or the upper body 1 and forms the lever 7. The lever 7 is provided with a lever groove 8 on the side away from the extension platform 62.

[0038] The extension platform 62 can be operated by either pushing it upwards directly with your hand or by pinching it to control its movement. The handle 3 extends away from the hinge point with the lower body 2 and extends away from the lower body 2 or the upper body 1 to form a lever 7. The lever 7 and the extension platform 62 can be used together, that is, by pinching the lever 7 and the extension platform 62 with your fingers respectively, so as to control the movement of the extension platform 62 more effortlessly.

[0039] It should be noted that fingers can be placed in the leverage groove 8. Due to the obstruction of the inner wall of the leverage groove 8, it is more difficult for the fingers placed on the leverage member 7 to come off, making it easier to control the extension table 62.

[0040] Furthermore, in this embodiment, a groove 9 is provided on the side of the handle 3 away from the lower body 2 or the upper body 1. The slider 61 is slidably connected within the groove 9 and is confined within it. The slider 61 slides along the length of both sides of the groove 9. Compared to being located on the side of the handle 3, the slider 61 is located on the side of the handle 3 away from the upper body 1 or the lower body 2, making the extension platform 62 and the lever 7 easier to design and reducing manufacturing difficulties. Figure 1 As shown, in a preferred embodiment, the slider 61 and the extension stage 62 are an L-shaped integral structure, which facilitates manufacturing.

[0041] Specifically, in this embodiment, the control component 6 further includes a spring 10. The spring 10 is located within the slide groove 9, and its two ends abut against one end of the slide groove 9 and the slider 61, respectively. The vertical cross-section of the first locking block 4 facing the end of the second locking block 5 gradually decreases in the direction towards the second locking block 5, and the vertical cross-section of the second locking block 5 facing the end of the first locking block 4 gradually decreases in the direction towards the first locking block 4. The spring 10 is disposed between the slider 61, the first locking block 4, and the handle 3, and the spring 10 continuously provides a hinge to the handle 3 towards the slider 61. Before the handle 3 is closed, the slider 61 does not need to be moved. The handle 3 can be rotated directly to approach the upper body 1. When the first locking block 4 contacts the second locking block 5, the first locking block 4 is compressed, the spring 10 contracts, and the first locking block 4 will automatically move upward. When the first locking block 4 is no longer compressed, the spring 10 will press the first locking block 4 downward, so that the first locking block 4 and the second locking block 5 are locked together, which simplifies the closing process of the handle 3 and makes the locking process of the upper body 1 and the lower body 2 more concise.

[0042] More specifically, in this embodiment, a limiting structure 11 is also included. The limiting structure 11 includes a limiting member 111, a limiting groove 112, a first torsion spring 113, and a rotating rod 114. The limiting member 111 is disposed on the upper body 1, and the limiting groove 112 is disposed on the side of the handle 3 facing the upper body 1 or the lower body 2. The limiting member 111 matches the limiting groove 112. The rotating rod 114 is connected to the limiting member 111 and is rotatably connected to the upper body 1. One end of the first torsion spring 113 is fixed to the upper body 1. The other end of the first torsion spring 113 is sleeved on the rotating rod 114. As the handle 3 gradually closes, the limiting member 111 will gradually enter the limiting groove 112, and the limiting member 111 will gradually become vertical as the handle 3 rotates. Due to the position difference between the hinge point of the handle 3 and the rotation center point of the limiting member 111, when the handle 3 is closed, the limiting member 111 will press against the top of the limiting groove 112 to achieve the purpose of locking the position. The first torsion spring 113 will continuously provide the rotating rod 114 with a force to rotate the main body 1 upward.

[0043] In a preferred embodiment, the lower body 2 is provided with a second torsion spring 12 and a connecting rod 13. The handle 3 is hinged to the lower body 2 via the connecting rod 13. The connecting rod 13 is rotatably connected to the lower body 2. The second torsion spring 12 is sleeved on the connecting rod 13, with one end abutting against the lower body 2 and the other end abutting against the handle 3. The second torsion spring 12 will continuously provide the handle 3 with a force to rotate the handle 3 in the closing direction, assisting the handle 3 to remain closed.

[0044] like Figure 1 As shown, in this embodiment, an inner tube 14 is also included, which is connected to the top of the upper body 1. The inner tube 14, the upper body 1, and the lower body 2 are coaxially arranged to form an axial through hole. The inner tube 14 is provided with a groove. Since the inner tube 14 and the fitting are interference-fitted, the groove facilitates the insertion of the fitting into the inner tube 14. The structure of the groove is as follows: Figure 1 As shown, this is existing technology, so it will not be explained in detail here. After the fitting is inserted into the inner tube 14, the fitting is fixed to the inner tube 14 by bolts.
