[0003] At present, most lifting structures are Z-shaped structures, with cylinders connected to diagonal rods and driven by cylinders. However, the adjustable height of this lifting structure is not high. In order to increase the adjustable height, multiple connecting rods connected together are arranged crosswise. When a group of crossed connecting rods are driven to rise by structures such as cylinders, the other connecting rods connected thereto will rise synchronously, thereby increasing the adjustable height. However, this structure is limited by the supporting strength of the connecting rods themselves, and as the connecting rods rise, the rod width decreases, and the stability of the support will decrease.

[0028] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not used to limit the present application.

[0029] Reference Figures 1 to 3 In one embodiment of the present utility model, a double lifting structure is proposed, including a first lifting structure 1 and a second lifting structure 6. The first lifting structure 1 includes a lifting base 2, a first scissor-type structure 3 and a stabilizing bracket 4. The first scissor-type structure 3 is connected to the lifting base 2. The stabilizing bracket 4 is provided with a first rotating end 41 for the first scissor-type structure 3 to rotate stably on one side corresponding to the first scissor-type structure 3, and a first sliding end 42 for the first scissor-type structure 3 to slide stably on the other side. The upper end of the first scissor-type structure 3 is rotatably connected to the side of the sliding end thereof with a driving structure 31; the second lifting structure 6 includes a first scissor-type structure 3 and a first sliding end 42 for the first scissor-type structure 3 to slide stably. Two scissor-type structures 61 and a mounting bracket 62, the second scissor-type structure 61 is connected to the mounting bracket 62, and the stabilizing bracket 4 is provided with a second rotating end 45 on one side corresponding to the second scissor-type structure 61 for stable rotation of the second scissor-type structure 61, and a second sliding end 46 on the other side for stable sliding of the second scissor-type structure 61. The second sliding end 46 and the first sliding end 42 are on the same side of the stabilizing bracket 4, and a conductive structure 7 is provided between the second sliding end 46 and the first sliding end 42. The second scissor-type structure 61 is rotatably connected to one end of the conductive structure 7, and the first scissor-type structure 3 is slidably connected to the other end of the conductive structure 7.

[0030] The first lifting structure 1 and the second lifting structure 6 are connected to each other by a stabilizing bracket 4. In order to facilitate the adjustment of the first scissor-type structure 3 so that it can be stably raised / lowered, a first rotating end 41 is provided on one side of the stabilizing bracket 4, and a first sliding end 42 is provided on the other side.

[0031] Similarly, in order to facilitate the adjustment of the second scissor-type structure 61, the stabilizing bracket 4 is provided with a second rotating end 45 and a second sliding end 46 above the first scissor-type structure 3 to efficiently adjust the second scissor-type structure 61. The first rotating end 41 and the second rotating end 45 are on the same side of the stabilizing bracket 4, which can make the two lifting structures more stable during adjustment and avoid damage during adjustment.

[0032] The first sliding end 42 and the second sliding end 46 are on the same side of the stabilizing bracket 4. A conducting structure 7 is provided between the first sliding end 42 and the second sliding end 46, which enables the driving structure 31 to synchronously drive the second lifting structure 6 when driving the first lifting structure 1, thereby ensuring the adjustment sensitivity and structural strength.

[0033] The driving structure 31 is installed on the lifting base 2. At the same time, the lifting base 2 can be provided with protective pads at its four corners to make the entire lifting structure more stable. The driving structure 31 can be composed of a driving motor, a push rod, and a pedal. The pedal is installed on the outer wall of the lifting base 2, which is convenient for operation, and the driving motor can make the push rod easy to extend and retract, so as to achieve the effect of pushing the first scissor-type structure 3 to make it rise and fall. Through the cooperation of the first scissor-type structure 3, the second scissor-type structure 61, the conductive structure 7, and the driving structure 31, the adjustable range of the mounting bracket 62 can be stably and effectively improved. The mounting bracket 62 can be covered with structures such as a hanging basket, so that the double lifting structure of the present application has a larger adjustable range and a stronger structure.

[0034] When it is necessary to lift the basket or other similar structure connected to the mounting bracket 62, the driving structure 31 drives the first scissor-type structure 3 to move the first sliding end 42 toward the first rotating end 41, so as to lift the stable bracket 4. When the first sliding end 42 moves, the first scissor-type structure 3 also moves in the chute provided in the conductive structure 7, thereby driving the second lifting structure 6 to rise through the conductive structure 7. After the mounting bracket 62 is installed with baskets of different specifications, the second lifting structure 6 will be supported to different heights. The second lifting structure 6 is rotatably connected to the conductive structure 7, and the first lifting structure 1 is slidably connected to the chute provided in the conductive structure 7. With the help of the conductive structure 7, the first lifting structure 1 can be lifted and lowered stably.

[0035] When the entire structure needs to be lowered, the driving structure 31 works in reverse, and the first sliding end 42 moves away from the first rotating end 41 to quickly reduce the height. The above structure can increase the adjustable height range of the mounting bracket 62 and make the adjustment more flexible.

[0036] See also Figures 1 to 3 In one embodiment of the present application, the second sliding end 46 includes a mounting frame 47 and a stabilizing rod 48. The mounting frame 47 is parallel to the stabilizing bracket 4 and is connected to the side wall of the stabilizing bracket 4. A sliding cavity is formed through the mounting frame 47 and the stabilizing bracket 4; the stabilizing rod 48 is passed through the sliding cavity and is connected to the second scissor-type structure 61. The conductive structure 7 is rotatably connected to the stabilizing rod 48 and is slidably connected to the inner wall of the stabilizing bracket 4.

[0037] The second sliding end 46 is installed on the outer wall of the stabilizing bracket 4, and the mounting frame 47 can be used to make the width of the stabilizing bracket 4 wider, so that after the mounting bracket 62 is installed with the basket and other structures, the stabilizing bracket 4 can be stably loaded with the assistance of the mounting frame 47 to ensure the stability of the installation. The sliding cavity opened in the mounting frame 47 and the stabilizing bracket 4 is used to limit and ensure the stability of the movement trajectory of the stabilizing rod 48. The second scissor-type structure 61 is connected to the end of the stabilizing rod 48, and the conductive structure 7 is rotatably connected to the stabilizing rod 48, which can ensure the stability of the force on the stabilizing rod 48 and enable the mounting bracket 62 to rise and fall as needed.

[0038] See also Figure 2 In one embodiment of the present application, a reinforcing rod 49 is provided in the stabilizing bracket 4, and the reinforcing rod 49 and the stabilizing rod 48 are arranged in parallel. The stabilizing bracket 4, the reinforcing rod 49, the mounting frame 47, and the second rotating end 45 constitute a mounting platform.

[0039] The reinforcing rod 49 can be used to bear the load and protect the stabilizing bracket 4 at the same time, preventing the stabilizing bracket 4 from being subjected to excessive pressure and structural damage. The installation platform can widen the area of ​​the stabilizing bracket 4, so that the stabilizing bracket 4 has a better bearing capacity.

[0040] See also Figures 1 to 2 In one embodiment of the present application, the stabilizing bracket 4 and the lifting base 2 enclose an adjustment space 5, the first scissor-type structure 3 is disposed in the adjustment space 5, and the first scissor-type structure 3 is connected to the end face of the conductive structure 7 facing away from the stabilizing bracket 4.

[0041] The adjustment space 5 can provide adjustment for the state of the first scissor-type structure 3. The first scissor-type structure 3 is located inside the stabilizing bracket 4 and the lifting base 2, so that the stabilizing bracket 4 and the lifting base 2 can protect the first scissor-type structure 3. The conductive structure 7 is located between the first scissor-type structure 3 and the second scissor-type structure 61 to ensure the transmission of the pulling force of the driving structure 31, so that the lifting structure can be stably adjusted efficiently and quickly according to needs.

[0042] See also Figures 2 to 3 In one embodiment of the present application, the first sliding end 42 includes a sliding frame 43 and a sliding rod 44. The sliding frame 43 is connected to the bottom of the stabilizing bracket 4, and the sliding frame 43 is provided with a sliding groove facing the first scissor-type structure 3; the sliding rod 44 is slidably connected to the sliding groove, and a matching groove is provided at one end of the conductive structure 7 away from the second scissor-type structure 61. The matching groove gradually extends in the direction facing the second scissor-type structure 61, and the sliding rod 44 is passed through the matching groove.

[0043] The sliding frame 43 is provided with a sliding groove toward the adjustment space 5. When the first sliding end 42 of the first scissor-type structure 3 is connected to the sliding groove, the adjustment space 5 can better accommodate the first lifting structure 1, which can protect the first scissor-type structure 3. The sliding rod 44 is slidably connected to the sliding groove, and is slidably connected to the matching groove of the conductive structure 7 from the outside to the inside and is rotatably connected to the first scissor-type structure 3. Even if a similar frame structure is installed in the second lifting structure 6 to support it in advance, the first lifting structure 1 can be freely lifted and lowered through the matching groove, so that the double lifting structure can be adjusted more flexibly.
