[0017] The present invention will be further described in conjunction with the accompanying drawings and embodiments.

[0018] like Figures 1-3 As shown, the lifting double telescopic device of this utility model includes: Lifting plate 1; The movable plate 2 is positioned below the lifting plate 1; The multiplier plate 3 is positioned below the movable plate 2; The first transmission mechanism 4 is disposed on one side of the lifting plate 1 and slidably connected to the lifting plate 1, and is used to drive the lifting plate 1 to perform lifting operations; The second transmission mechanism 5 is installed between the lifting plate 1 and the moving plate 2, and is used to drive the moving plate 2 to move forward to form the first stroke of the multiplier plate 3; The third transmission mechanism 6 is installed between the moving plate 2 and the multiplier plate 3. Under the action of the second transmission mechanism 5, it further drives the multiplier plate 3 to move forward to form a second stroke. During the movement of the second transmission mechanism 5, one end of the chain is fixed to the bottom of the lifting plate 1, and the other end is fixedly connected to the second connecting block 64. The bottom of the second connecting block 64 is connected to the multiplier plate 3. The sprocket 62 is rotatably installed on the moving plate 2. During the movement of the moving plate 2 driven by the second transmission mechanism 5, the two sprockets 62 move forward. Because the fixed connection between the chain and the lifting plate 1 is a fixed point, the front sprocket 62 drives the entire chain to move forward. During the movement of the rear sprocket 62, due to its forward movement and rotatable installation on the moving plate 2, the chain that is in frictional contact with the sprocket 62 is guided to work forward, driving the second connecting block 64 fixed on the chain to move forward, thereby driving the multiplier plate 3 to perform the second stroke.

[0019] The first transmission mechanism 4 includes: The first chain 41 is installed on the left and right sides of the lifting plate 1 and is fixedly connected to the left and right ends of the lifting plate 1. The first driving component 42 is used to drive the first chain 41 on one side for transmission. The output end of the first driving component 42 is connected to the first chain 41. In the specific implementation of this utility model, the first driving component 42 includes a lifting motor, which drives the lifting shaft to rotate, so that the driving wheel installed at the bottom of the lifting shaft rotates. The driving wheel and the driven wheel mesh and drive each other, driving the driven wheel to rotate. The first chain 41 is sleeved on the transmission wheel, thereby driving the first chain 41. The driven wheel drives the transmission wheel to rotate, thereby driving the first chain 41 to perform transmission.

[0020] The second transmission mechanism 5 includes: Rack 51 is fixed on the movable plate 2; The gear 52 meshes with the rack 51 to drive the movable plate 2, which is fixedly connected to the rack 51, to move forward to form a first stroke or to move backward. During the rotation of the second driving member 53, the gear 52 and the rack 51 mesh with each other to drive the movable plate 2 to move. The second driving component 53, which drives the gear 52 to rotate, is mounted on the lifting plate 1.

[0021] The third transmission mechanism 6 includes: The second chain 61 is installed on the movable plate 2; A sprocket 62 is rotatably mounted above the movable plate 2 and is used to pull and guide the second chain 61 to move synchronously when the movable plate 2 moves; the second chain 61 is sleeved on the sprocket 62. The first connecting block 63 is fixed on the second chain 61 and its top is fixedly connected to the bottom surface of the lifting plate 1. It is used to fix a point on the second chain 61. The first connecting block 63 fixes a point on the second chain 61 to prevent the entire chain from moving along with the sprocket 62 and failing to play a dragging role when the moving plate 2 drives the sprocket 62 to move forward or backward. The second connecting block 64 is fixed at its upper end to the second chain 61 and at its lower end to the multiplier plate 3, and is used to connect the multiplier plate 3 to move so as to form a second stroke.

[0022] The movable plate 2 is a hollowed-out U-shaped plate; the two sprockets 62 are respectively installed at the front and rear ends of the movable plate 2; used to form the multiplication distance that the second connecting block 64 drives the multiplier plate 3 to travel.

[0023] The starting positions of the first connecting block 63 and the second connecting block 64 are located on the left and right sides of the second chain 61, respectively. During the maximum double stroke, the second connecting block 64 is located at the last end of the connection of the second chain 61 and at the hollowed-out part in the middle of the moving plate 2, while the first connecting block 63 is located at the foremost end of the connection of the second chain 61 and at the hollowed-out part in the middle of the moving plate 2. At this time, the length of the second stroke is the length traveled by one side of the second chain 61, which is the distance between the two sprockets 62.

[0024] The sprockets 62 are provided in pairs, one of which is the active pull sprocket 62 closer to the direction of movement, and the other is the driven guide sprocket 62 farther away from the direction of movement. In this utility model, the multiplication direction is the forward direction. Therefore, during the forward movement, the front wheel is the active pull sprocket 62, and the rear wheel is the driven guide sprocket 62.

[0025] Working principle: After the first driving component 42 is in operation, it drives the first chain 41 to perform transmission work, thereby driving the lifting plate 1 to perform transmission work on the first chain 41, so that the lifting plate 1 can move up and down. The second driving component 53 drives the gear 52 to rotate, causing the rack 51 meshing with the gear 52 to drive the moving plate 2 to move. The multiplier plate 3 is slidably connected below the moving plate 2, further driving the multiplier plate 3 to form the first stroke. As the moving plate 2 moves forward, the sprocket 62 pulls the second chain 61 forward as well. The lifting plate 1 does not move at this time, so the fixed position of the second chain 61, which is fixedly connected to the first connecting block 63, does not move. As the sprocket 62 moves forward continuously, it pulls the second chain 61 to rotate forward, thereby driving the multiplier plate 3 to form the second stroke. This invention utilizes the change in relative displacement between the first connecting block 63 and the sprocket 62 to provide driving force, causing the chain to rotate. This, in turn, drives the multiplier plate 3 connected to the second connecting block 64 to move as well. Through this process, the multiplier plate 3 achieves double the stroke. Content not described in detail in this specification is prior art known to those skilled in the art.

[0026] The embodiments described above are merely preferred embodiments of the present invention, and are described in a relatively specific and detailed manner. However, the present invention is not limited to these embodiments. It should be noted that for those skilled in the art, any improvements made without departing from the spirit of the present invention fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
