Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] See Figures 1-4 This utility model provides the following two technical solutions:

[0024] First embodiment: A foot-folding mechanism for a folding product includes a support column 1, the support column 1 being connected to a folding component for folding the foot of the folding product, the folding component including: a docking component 2, mounted on the support column 1 for mounting to the bottom support end of the folding product, the docking component 2 including a docking block 21 mounted on the support column 1, the docking block 21 having a docking hole 22 matching the bottom of the folding product; and a base 3, mounted on the bottom of the support column 1 for providing support.

[0025] Four sets of support leg assemblies 4 are all installed on the support column 1 and connected to the base 3 to provide support and have a folding function. The support leg assembly 4 includes four sets of mounting frames 41 installed on the base 3. Four sets of folding assemblies 43 are installed on the middle of the outer side of the support column 1. The folding assembly 43 includes a bracket 431 that is rotatably connected to the side of the support column 1. The bottom of the bracket 431 is equipped with a foot 432. The support block 433 that is rotatably connected to the bottom mounting frame 41 and slidably connected to the end of the bracket 431 near the base 3 is slidably connected to the bottom mounting frame 41. The mounting frame 41 is connected with a second bolt assembly 42 for locking the support block 433. The support column 1 is provided with a transmission component 44 for controlling the synchronous rotation of the four sets of brackets 431. The mounting frame 41 is provided with two sets of first mounting holes that match the second bolt in the second bolt assembly 42. The bottom of the support block 433 is provided with a second mounting hole that matches the second bolt corresponding to the first mounting hole. The threaded end of the second bolt in the second bolt assembly 42 is threadedly connected to a second nut that fits with the mounting frame 41.

[0026] The folding assembly 43 also includes a second magnet 434 installed on the side of the bracket 431 near the support column 1 and used to attract the support block 433. The support block 433 is made of metal, and the bottom of the foot 432 is flush with the bottom of the base 3. The transmission component 44 includes a cross frame 441 that is slidably connected to the inside of the support column 1. Four sets of racks 442 that are slidably connected to the support column 1 are respectively installed on the four sides of the cross frame 441. A gear 443 that meshes with the rack 442 is coaxially fixedly connected to the rotating end of the bracket 431. The inside of the support column 1 is provided with a cross groove that is slidably connected to the cross frame 441, and the side of the support column 1 is provided with a sliding groove that is slidably connected to the rack 442. The cross frame 441, the four sets of mounting frames 41, the second bolt assembly 42, the bracket 431, the foot 432, the support block 433, the second magnet 434, the rack 442, and the gear 443 cooperate with each other to increase the contact range between the foot of the device and the ground, improve the support effect, and facilitate the synchronous folding and storage of the foot support end.

[0027] The main difference between the second implementation method and the first implementation method is that:

[0028] The docking component 2 also includes a first bolt assembly 23 connected to the docking block 21. The non-threaded end of the first bolt in the first bolt assembly 23 is slidably connected to the docking block 21. The threaded end of the first bolt in the first bolt assembly 23 is threadedly connected to a first nut that fits with the docking block 21. The base 432 is made of metal. A first magnet 24 is installed on the outer side of the top of the support column 1 corresponding to the base 432. The bottom docking end of the folded product is inserted into the docking hole in the docking block 21. The docking block 21 is fixedly connected to the bottom of the folded product by the cooperation of the first bolt and the first nut in the first bolt assembly 23. The first magnet 24 is convenient for adsorbing the base 432 after folding.

[0029] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0030] In use, the user disconnects the first bolt assembly 23 on the docking block 21 from the bottom docking end of the folded product, allowing the bottom of the folded product to be pulled out from the docking hole 22 inside the docking block 21. This separates the second bolt assembly 42 from the support block 433. The user then rotates the support block 433, causing it to adhere to the second magnet 434. By moving a set of brackets 431, the brackets 431 drive the bottom foot 432, support block 433, and second magnet 434 to rotate, causing the bottom foot 432 to adhere to the first magnet 24. During this process, the set of brackets 431 drives the rack 442 to move vertically through the gear 443 at its rotating end. The vertically moving rack 442 drives the cross frame 441 and the remaining racks 442 to move vertically. The remaining racks 442, in conjunction with the remaining gears 443, drive the remaining brackets 431, bottom feet 432, support blocks 433, and second magnets 434 to rotate synchronously, achieving synchronous folding.
