[0036] This invention proposes a lifting bracket to solve the technical problem that drying rods easily get stuck in scissor racks, causing deformation of the scissor racks or drying rods.

[0037] In embodiments of the present invention, such as Figures 1 to 3 As shown, the lifting support includes a first movable rod 3, a second movable rod 4, a drying rod 5, and multiple hinged rods 11. The ends of two adjacent hinged rods 11 are hinged together, and the middle part is hinged to another hinged rod 11 to form a scissor frame 1. A limit member 2 is provided on the hinged rod 11 located at the bottom of the scissor frame 1. The first movable rod 3 is hinged to the hinged rod 11 and is located at the bottom of the scissor frame 1. The second movable rod 4 is hinged to the end of the first movable rod 3 away from the hinged rod 11, and the drying rod 5 is connected to the end of the second movable rod 4 away from the first movable rod 3.

[0038] The limiting member 2 is used to limit the rotation angle of the first movable rod 3 on the hinge rod 11, so as to restrict the drying rod 5 outside the movement area of ​​the scissor frame 1.

[0039] The present technical scheme hingedly connects multiple hinged rods 11 to form a scissor frame 1, thereby improving the stability of the lifting support by taking advantage of the good stability of the scissor frame 1 itself, and avoiding the shaking of the lifting support during lifting; the first movable rod 3 is hingedly connected to the bottom of the scissor frame 1, the second movable rod 4 is hingedly connected to the first movable rod 3, and the drying rod 5 is hingedly connected to the second movable rod 4, so that when drying is needed, the drying rod 5 can be hung on the scissor frame 1, and then clothes can be hung on the drying rod 5 to achieve drying; when drying is not needed, the drying rod 5 can be turned up and folded by rotating the first movable rod 3 and the second movable rod 4, and the drying rod 5 can be overlapped on the hinged rod 11 at the bottom of the scissor frame 1, thereby achieving the folding of the lifting support to reduce the size of the lifting support; the hinged rod 11 at the bottom of the scissor frame 1 is provided with a limiting piece 2, which is used to limit the rotation angle of the first movable rod 3 on the hinged rod 11, so that the first movable rod 3 cannot be completely rotated to the position close to the upper surface of the hinged rod 11, thereby taking the hinged point of the drying rod 5 and the hinged rod 11 as the center, reducing the distance between the drying rod 5 and the center, and increasing the distance between the drying rod 5 and the hinged point of the middle of the hinged rod 11, so as to limit the drying rod 5 outside the movement area of the scissor frame 1, avoid the drying rod 5 from extending into the scissor frame 1, and cause the drying rod 5 to be stuck when the scissor frame 1 is lifted and tightened, thereby causing the bending deformation of the drying rod 5 or the scissor frame 1.

[0040] In the present embodiment, as shown in Figure 1 , the end portions of the adjacent two hinged rods 11 are hingedly connected to form a hinged assembly, and all the hinged rods 11 are hingedly connected to form two groups of hinged assemblies, and then the middle portions of the hinged rods 11 in the two groups of hinged assemblies are hingedly connected one by one to form the scissor frame 1.

[0041] For the convenience of description, as shown in Figure 1 , the hinged points of the end portions of the adjacent two hinged rods 11 are named as edge hinged points 12, and the hinged points of the middle portions of the hinged rods 11 are named as middle hinged points. It can be understood that the movement area of the scissor frame 1 refers to the maximum movement area of the edge hinged points 12. By limiting the drying rod 5 outside the movement area of the scissor frame 1, the drying rod 5 will not extend between the adjacent two edge hinged points 12 when the lifting support is lifted, so that the movement of the drying rod 5 and the scissor frame 1 does not interfere with each other, avoiding the drying rod 5 from extending into the movement area of the scissor frame 1 and being stuck between the adjacent two edge hinged points 12, thereby causing the bending deformation of the drying rod 5 and the scissor frame 1 due to stress.

[0042] In the present embodiment, the drying rod 5 is used for drying clothes, and is especially suitable for drying quilts and other life supplies that cannot be hung on the clothes hanger 20. The provision of the first movable rod 3 and the second movable rod 4 can provide sufficient space between the drying rod 5 and the scissor frame 1, so as to facilitate the user to pass the quilt through the drying rod 5, thereby hanging the quilt on the drying rod 5 for drying; the hingedly connected first movable rod 3 and second movable rod 4 can fold the drying rod 5, thereby reducing the size of the lifting support.

[0043] In the embodiment, as shown in Figure 1 , the hanging rope 10 can be fixed on the central hinge point 13, and then the end of the hanging rope 10 away from the central hinge point 13 is fixed on the motor shaft, so that the lifting of the support can be realized by the forward rotation or reverse rotation of the motor.

[0044] In an example, during the folding of the drying rod 5, the rotation of the first movable rod 3 on the hinge rod 11 is not limited, so that after the first movable rod 3 rotates about 360°, the drying rod 5 is close to the upper surface of the hinge rod 11, and the distance between the drying rod 5 and the hinge point of the first movable rod 3 and the hinge rod 11 is approximately equal to the length of the drying rod 5, so that the distance between the drying rod 5 and the hinge point of the first movable rod 3 and the hinge rod 11 is larger, and the distance between the drying rod 5 and the central hinge point 13 is smaller, so that the drying rod 5 extends into the adjacent two edge hinge points 12, and when the support is lifted, the drying rod 5 is clamped in the scissor frame 1, causing the deformation of the drying rod 5 and the scissor frame 1. However, in the embodiment, the limiting piece 2 is arranged on the hinge rod 11 at the bottom of the scissor frame 1, so that the rotation angle of the first movable rod 3 on the hinge rod 11 is limited, thereby limiting the extension of the drying rod 5 into the adjacent two edge hinge points 12, and avoiding the deformation of the scissor frame 1 caused by the clamping of the drying rod 5.

[0045] In an embodiment, as shown in Figures 1 to 4 , the limiting piece 2 is a sliding groove, and the end of the first movable rod 3 is provided with a sliding rod 31, which is slidingly arranged in the sliding groove. The sliding groove is used to limit the sliding rod 31, so as to limit the rotation angle of the first movable rod 3 on the hinge rod 11. When the sliding rod 31 slides in the sliding groove, the groove wall of the sliding groove can limit the sliding of the sliding rod 31, and the sliding rod 31 is arranged on the first movable rod 3, so that the groove wall of the sliding groove can limit the movement of the first movable rod 3, and the first movable rod 3 is hinged with the hinge rod 11, so that when the first movable rod 3 rotates with the hinge point of the first movable rod 3 and the hinge rod 11 as the center, the sliding groove can limit the rotation angle of the first movable rod 3 on the hinge rod 11.

[0046] Optionally, the sliding groove is an arc-shaped groove, so that the sliding rod 31 can freely slide in the sliding groove.

[0047] In another optional embodiment, the limiting piece 2 is a limiting protrusion, which is located on the rotation path of the first movable rod 3 on the hinge rod 11, so as to limit the rotation angle of the first movable rod 3 on the hinge rod 11, and limit the drying rod 5 outside the movement area of the scissor frame 1. Specifically, the limiting protrusion is arranged on the path of the upward rotation of the first movable rod 3.

[0048] In an embodiment, as shown in Figure 1 and Figure 2As shown, the lifting support further comprises a third movable rod 6, both ends of the third movable rod 6 are hinged with the first movable rod 3 and the second movable rod 4 respectively, so as to connect the first movable rod 3 and the second movable rod 4 through the third movable rod 6, increase the number of degrees of freedom when the drying rod 5 is folded upward, reduce the height of the drying rod 5 relative to the hinged rod 11 when the drying rod 5 is placed on the hinged rod 11, so that the drying rod 5 can be stably placed on the hinged rod 11, and the drying rod 5 is prevented from falling off the hinged rod 11.

[0050] Optionally, as shown, Figure 5 The third movable rod 6 comprises two sub-rods, the two sub-rods are arranged in parallel, both the two sub-rods are hinged with the first movable rod 3 and the second movable rod 4, and the first movable rod 3 and the second movable rod 4 are clamped between the two sub-rods, so as to form a double-rod structure, improve the strength of the connection between the first movable rod 3 and the second movable rod 4, and also improve the stability when the first movable rod 3 and the second movable rod 4 rotate. Specifically, Figure 4 The first movable rod 3, the second movable rod 4 and the third movable rod 6 are respectively shown in two different embodiments. Figure 5

[0051] In an embodiment, as shown in Figure 1 and Figure 2 The sum of the lengths of the second movable rod 4 and the third movable rod 6 is greater than the length of the first movable rod 3, so that the drying rod 5 can bypass the hinged point of the first movable rod 3 and the hinged rod 11, and be limited from sliding downward by the hinged point of the first movable rod 3 and the hinged rod 11, so as to stably place the drying rod 5 on the upper surface of the hinged rod 11.

[0052] In an embodiment, as shown in Figure 1 and Figure 3 The lifting support further comprises a frame 7, the frame 7 is connected with the bottom of the scissor frame 1, the first movable rod 3 is hinged on the frame 7, and the limiting piece 2 is arranged on the frame 7, and the limiting piece 2 is used to limit the rotation angle of the first movable rod 3 on the frame 7. By arranging the frame 7, the drying rod 5 can be conveniently placed on the frame 7 after being folded upward, and the stability of placing the drying rod 5 on the frame 7 is improved; by arranging the first movable rod 3 on the frame 7, the stability of the drying rod 5 when hanging is also improved, and it is also convenient to arrange other functional components on the frame 7.

[0053] Optionally, a horizontal rod can also be arranged at the end of the hinged rod 11 at the bottom of the scissor frame 1, so as to place the drying rod 5 on the horizontal rod after being turned upward.
