[0030] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of the present application.

[0031] As shown in Figures 1 to 4 and Figures 6-8 The embodiments of the present application provide a linkage type folding support, which comprises a connecting base 2 and a plurality of foldable legs 1 movably connected to the connecting base 2. The foldable legs 1 are rotatably connected to the connecting base 2, and the legs 1 can be unfolded or folded relative to the connecting base 2. The foldable legs 1 comprise support arms 11 and linkage arms 12. The roots 112 of the support arms 11 are fixedly connected to the roots of the linkage arms 12. The support arms 11 and the linkage arms 12 form a predetermined angle. The linkage type folding support further comprises a linkage mechanism 3 and a transmission mechanism 4. The linkage mechanism 3 moves along the height direction of the connecting base 2. The linkage mechanism 3 is provided with a transmission arm 31 corresponding to the transmission mechanism 4. The transmission mechanism 4 is movably connected to the end of the linkage arm 12 and the transmission arm 31. Rotating any one of the support arms 11 drives the transmission mechanism 4 to move through the linkage arm 12. The movement of the transmission mechanism 4 drives the transmission arm 31 to rise and fall, thereby driving the linkage mechanism 3 to move along the height direction of the connecting base 1. In turn, the remaining foldable legs 1 are driven to rotate relative to the connecting base 2, and are unfolded or folded synchronously. The linkage type folding support provided by the embodiments of the present application will be described in detail below.

[0032] As shown in Figures 1-6As shown in this embodiment of the invention, since the support arm 11 and the linkage arm 12 form a predetermined angle, and the foldable leg 1 is rotatably connected to the connecting base 2, when any one of the support arms 11 is rotated, the linkage arm 12 rotates under the lever action of the support arm 11. When the end 111 of the support arm 11 moves, the end of the linkage arm 12 moves vertically. At the same time, when the end of the linkage arm 12 moves vertically, the end of the linkage arm 12 drives the transmission mechanism 4 movably connected to it to move, and the movement of the transmission mechanism 4 drives the transmission arm 31 to move vertically. Since the number of linkage arms 12 corresponds to the number of transmission arms 31, and the number is the same, the linkage mechanism 3 also moves vertically. Therefore, the other linkage arms 12 movably connected to the linkage mechanism 3 move vertically, thereby driving the remaining foldable legs 1 to rotate relative to the connecting base 2, and simultaneously unfolding or folding.

[0033] like Figures 4 to 7 As shown in this embodiment of the invention, to achieve a good connection, the transmission mechanism 4 further includes a transmission block 40 and transmission shafts 41 disposed at both ends of the transmission block; the two ends of the transmission block 40 are respectively hinged to the ends of the linkage arm 12 and the transmission arm 31 via the transmission shafts 41. Specifically, for example, the transmission arm 31 is provided with a transmission through hole 30 or a groove, and the ends of the linkage arm 12 are hinged via the transmission shafts 41. Since the number of linkage arms 12 corresponds to the number of transmission arms 31, the number of foldable legs 1 can be set to 3 or 4 according to actual needs. Multiple foldable legs 1 are arranged in different positions on the connecting base 2.

[0034] like Figures 3 to 7 As shown in this embodiment of the invention, multiple foldable legs 1 are arranged at different positions on the connecting base 2. To prevent the linkage arm 12 and the transmission arm 31 from shifting during movement, it is necessary to restrict the direction of the linkage mechanism 3. The connecting base 2 is provided with a track mechanism 21 to restrict the reciprocating movement of the linkage mechanism 3. To further reduce costs and simplify the product structure, the track mechanism 21 is a column located at the center of the connecting base 1. The linkage mechanism 3 has a positioning through hole 33 at its center that matches the column. The column passes through the positioning through hole 33, and the linkage mechanism moves up and down along the column, maintaining the consistent movement direction of the transmission arms 31 arranged at different positions, preventing shifting.

[0035] like Figure 6 and Figure 7As shown in the embodiment of this utility model, in order to minimize product cost and reduce product size, a receiving space 20 is provided inside the connecting base 2, and the linkage mechanism 3 and the transmission mechanism 4 are disposed within the receiving space 20. It is understood that this utility model is not limited to this; the linkage mechanism 3 and the transmission mechanism 4 can also be disposed outside the connecting base 2.

[0036] like Figures 1 to 7 As shown in this embodiment of the invention, to increase the stability of the product structure, the connecting base 2 is provided with a rotating recess 22 or a rotating connecting hole, and the foldable support leg 1 has a rotating shaft 110, which rotates within the rotating recess 22 or the rotating connecting hole. The support arm 11 rotates rotatably along the rotating shaft 110.

[0037] like Figures 1 to 4 As shown in this embodiment of the invention, the foldable legs 1 are arranged in multiple sets evenly along the outer edge of the connecting base 2, and the multiple sets of support arms 11 are divided into equal sections of cylindrical bodies. For example, the multiple sets of support arms 11 are divided into multiple cylindrical bodies with fan-shaped interfaces by dividing a cylinder. The multiple sets of support arms 11 can also be divided into four quadrangular prisms by using quadrangular prisms.

[0038] like Figures 1 to 4 As shown in this embodiment of the invention, a bearing mechanism is provided on the connecting base, and an extension connecting mechanism 5 is provided on the bearing mechanism. The extension connecting mechanism 5 is a fastening bolt. To effectively maintain the stability of the connection, a silicone pad 50 is provided outside the extension connecting mechanism 5.

[0039] like Figures 4 to 7 As shown in this embodiment of the utility model, a protective bottom shell 100 is provided outside the connecting base.

[0040] In summary, the linkage folding bracket provided by this utility model embodiment, through a transmission mechanism and a plurality of foldable legs movably connected thereto, allows rotation of any one of the support arms. This support arm, via the linkage arm, drives the transmission arm to rise and fall, thereby causing the transmission mechanism to move in the height direction of the connecting base. This, in turn, causes the remaining foldable legs to rotate relative to the connecting base, thus simultaneously unfolding or folding them. Users do not need to open and secure each leg individually, making operation convenient and achieving one-button linkage, increasing ease of use.
