[0024] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the drawings. The described embodiments are part of the embodiments of the utility model, rather than all the embodiments.

[0025] Figure 1 This is a schematic diagram of the structure of a lifting device according to an embodiment of the utility model; Figure 2 This is a schematic diagram of the local structure of the sliding part of a lifting device according to an embodiment of the utility model; Figure 3 It is a schematic diagram of the local structure of a side frame of a lifting device in an embodiment of the utility model.

[0026] refer to Figure 1 , Figure 2 and Figure 3 The lifting device provided by the embodiment of the utility model includes a base 1; a side frame 2, two side frames 2 are fixedly installed on the base 1, and the two side frames 2 are parallel to each other in the vertical space, and a vertical downward track 21 is formed on the side of the side frame 2; a sliding part 3, two end surfaces of the sliding part 3 are provided with first rollers 31, and the first rollers 31 cooperate with the track 21 to limit the sliding part 3 to move in the vertical direction; a plurality of grooves 32 are provided on the side of the sliding part 3, and the grooves 32 are distributed side by side; the sliding part 3 includes a connecting part 33, and the connecting part 33 is used to connect and support the load; a spiral spring 4, the axis of the spiral spring 4 is installed in the groove 32, and the other end of the spiral spring 4 is connected to the side frame 2; a crossbeam 5, the crossbeam 5 is detachably connected to the two sliding parts 3, and is used to synchronize the displacement of the two sliding parts 3 on the side frame 2.

[0027] It should be noted that in Figure 1In order to show the details of the sliding part 3, the side frame 2 on the left is not shown. The spiral spring is also called a clockwork spring, one end of which is fixed and the other end is acted upon by torque; under the action of the torque, the spring material undergoes bending elastic deformation, causing the spring to twist in the plane, and the size of the deformation angle is proportional to the torque. A plurality of grooves 32 are provided on the side of the sliding part 3, and the grooves 32 are arranged side by side. The axis of the spiral spring 4 is installed in each groove 32, so that the spiral springs 4 are arranged side by side on the sliding part, forming a state in which multiple spiral springs 4 work in parallel. Reference Figure 1 or Figure 2 The axis of the spiral spring 4 is installed on the same shaft, so that each spiral spring 4 can output the same torque when lifting. The axis of the spiral spring 4 can also be installed on different shafts, so that when the lifting device is in different positions, each spiral spring 4 outputs different torques.

[0028] It should also be explained that after the support load is installed on the sliding part 3, under the action of the gravity of the support load, the stretching length of the plurality of volute springs 4 is L1. When a vertical downward force is applied to the support load or the sliding part 3, the stretching length of the plurality of volute springs 4 is L2, and the height of the entire lifting device being lowered is L2-L1. When the vertical downward force applied to the support load or the sliding part 3 is canceled, under the action of the elastic force of the plurality of volute springs 4, the stretching length of the volute springs is restored to L1, and the height of the entire lifting device being raised is L2-L1. Thus, when the plurality of volute springs 4 are connected in parallel, the lifting and lowering of the lifting device is realized by using mechanical elastic force instead of the motor.

[0029] refer to Figure 2 In one embodiment, the first roller 31 is installed on the two end surfaces of the sliding part 3 through a U-shaped component, the bottom surface of the U-shaped component is connected to the end surface of the sliding part 3, and the axis of the first roller 31 is installed on the side of the U-shaped component.

Multiple spiral springs 4 are installed in each groove 32, and the axis of the spiral springs 4 in the same groove 32 is installed at different heights, thereby forming a series working state of the spiral springs 4, so that when the lifting device is in different positions, each spiral spring 4 outputs different torques and provides different lifting forces.

[0031] In one embodiment, a locking module 6 is further included. The locking module 6 is disposed on the base 1 and is used to lock the crossbeam 5 in a vertical direction.
