[0002] A lifting device is a mechanical device that can be raised or lowered, and can carry people or objects to change height. Large lifting devices generally use hydraulic drive or chain drive to adjust the height, while micro lifting devices use screw drive adjustment. Micro lifting devices are mostly used in experiments, and can carry experimental equipment to change height.

[0003] When the existing micro-lifting device is in use, the placement plate on the top of the device is used to place objects. However, the placement plate for placing objects is fixedly connected to the lifting frame and the placement plate is not detachable.

In addition, the existing micro-lifting device is placed by supporting feet at the bottom plate. After placement, the device has poor stability. When the desktop used to place the micro-lifting device is not level, the device is prone to sliding, which affects the experimental effect.

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] As shown in Figures 1 to 4, a micro-lifting device includes a supporting base plate 1, a lifting frame 2 is connected to the supporting base plate 1, and a supporting foot 3 is installed on the lower surface of the supporting base plate 1, a stabilizing structure 4 is installed on the supporting base plate 1, a placing structure 5 is installed on the upper end of the lifting frame 2, an adjusting frame 6 is fixedly installed on the upper surface of the supporting base plate 1, and the adjusting frame 6 is connected to the lower end of the lifting frame 2, the supporting foot 3 is symmetrically arranged on the lower surface of the supporting base plate 1, the upper end of the lifting frame 2 is connected to a fixing frame 7, and a through hole 8 is opened at the corner of the fixing frame 7, the placing structure 5 is installed on the fixing frame 7, and the placing structure 5 is installed on the lifting frame 2 through the fixing frame 7, the lifting frame 2 is provided with a connecting rod 9, and the number of the connecting rods 9 is two, one of the connecting rods 9 is opened with a round hole, and the other connecting rod 9 is provided with a threaded hole, the connecting rod 9 is provided with an adjusting component 10, and the adjusting component 10 includes a driving screw, a limit block and an adjusting button, the stabilizing structure 4 is symmetrically arranged on the supporting base plate 1, and the stabilizing structure 4 is threadedly connected to the supporting base plate 1.

[0022] When using the micro-lifting device, the micro-lifting device is stably placed on the experimental table through the support feet 3 on the lower surface of the supporting base plate 1, and then the micro-lifting device can be used to conduct experiments. During the experiment, the corresponding objects are placed on the placement structure 5 installed on the upper surface of the fixing frame 7, and the driving screw is rotated by the adjusting knob in the adjusting component 10. The driving screw is connected to a thread of the connecting rod 9 close to the adjusting knob, and the other end of the driving screw is relatively fixed to the other connecting rod 9 through a limit block. Therefore, when the driving screw rotates, the two connecting rods 9 will be relatively displaced, thereby driving the lifting frame 2 to descend or ascend, and then lifting and descending with the placement structure 5. In this process, the lower end of the lifting frame 2 moves along the adjusting frame 6, which can ensure the stability of the lifting frame 2 during adjustment. When the placement structure 5 is moved to the appropriate position through the lifting frame 2 After the height is reached, the items placed are at an appropriate height. The staff conducts the experiment, takes away the items after use, adjusts and stores the entire micro-lifting device, and then stores the micro-lifting device. When using the micro-lifting device, the entire micro-lifting device can be flexibly moved to a suitable place, and the use flexibility is high. Before the experiment, if the level of the desktop where the micro-lifting device is placed is poor, the stabilizing structure 4 can be installed on the supporting base plate 1, and then the micro-lifting device can be placed. After the micro-lifting device is placed, the stabilizing structure 4 is adjusted so that the lower end of the stabilizing structure 4 is adsorbed on the desktop, thereby ensuring that the entire micro-lifting device has good stability and ensures the use effect. If the placement structure 5 is damaged and needs to be replaced, it can be quickly disassembled and replaced.

[0023] Through the above embodiment, the stabilizing structure 4 includes an adjusting screw 401, a connecting block 402 and a suction cup 403. The adjusting screw 401 passes through the supporting base plate 1, the connecting block 402 is connected to the suction cup 403, and the connecting block 402 is connected to the lower end of the adjusting screw 401. The stabilizing structure 4 also includes a hexagonal groove 404. The connecting block 402 is fixedly connected to the suction cup 403, and the connecting block 402 is fixedly connected to the lower end of the adjusting screw 401. The hexagonal groove 404 is opened at the upper end of the adjusting screw 401. The placing structure 5 includes an anti-slip placing plate 501 and a connecting screw 502. The connecting screw 502 is installed on the lower surface of the anti-slip placing plate 501, and the anti-slip placing plate 501 is connected to the upper end of the lifting frame 2. The placing structure 5 also includes a connecting nut 503. The anti-slip placing plate 501 is placed on the fixing frame 7. The connecting screw 502 passes through the fixing frame 7. The through hole 8 is threadedly connected to the lower end of the connecting screw 502, and the connecting nut 503 contacts the lower surface of the fixing frame 7. Through the provided stable structure 4, when the device is placed on the desktop, the stable structure 4 is used to adsorb it to the desktop, which can ensure the stability of the device and avoid the device sliding due to an uneven desktop. The adjusting screw 401 in the stable structure 4 is threadedly connected to the supporting base plate 1, which can be adjusted quickly and has a self-locking effect after adjustment, ensuring flexibility and stability in use. The upper end of the lifting frame 2 is installed with a detachable placement structure 5 through the fixing frame 7, which is convenient for removing the placement structure 5 for replacement, and has high flexibility in use. The anti-slip placement plate 501 in the placement structure 5 is installed by the connecting screw 502 and the connecting nut 503, which is easy and quick to install and can ensure stability after installation.

[0024] When installing the stabilizing structure 4, the adjusting screw 401 is fixed to the connecting block 402, and the connecting block 402 is connected to the suction cup 403. Pick up the entire micro-lifting device and screw the adjusting screw 401 from bottom to top into the hole on the supporting base plate 1 until the connecting block 402 contacts the lower surface of the supporting base plate 1. In this way, the installation of the stabilizing structure 4 is completed. After the micro-lifting device is placed on the desktop, in the initial state, the lower surface of the suction cup 403 is higher than the lower surface of the supporting foot 3, so the suction cup 403 is in a suspended state. If it is necessary to use the stabilizing structure 4 to ensure the stability of the entire micro-lifting device, the end of the hexagonal wrench can be inserted into the hexagonal groove 404 at the upper end of the adjusting screw 401, and the adjusting screw 401 is rotated and lowered on the supporting base plate 1, thereby bringing the suction cup 403 on the connecting block 402 down until the suction cup 403 is adsorbed on the desktop. The anti-skid placing plate 501 has good anti-skid property when supporting and placing items, which can prevent items from sliding and falling, and ensure the stability of the placement of items. When the anti-skid placing plate 501 needs to be disassembled, the connecting nut 503 is rotated with a tool to unscrew the connecting nut 503 from the lower end of the connecting screw 502, and then the anti-skid placing plate 501 is moved upwards, so that the connecting screw 502 is pulled out from the through hole 8, and the placement structure 5 is disassembled and replaced. After the operation is completed, the placement structure 5 can be installed. The structure is simple and the use effect is good.
