For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0045] The utility model is described in detail below in conjunction with the accompanying drawings.

[0046] like Figure 1 and 2 As shown, a stage lifting device that can be assembled and used has a plurality of lifting units 100, and the lifting units 100 include:

[0047] Fixed frame 1;

[0048] An outer frame 2, fixed to the fixing frame 1;

[0049] The inner frame 3 is slidably mounted on the outer frame 2 and can move up and down relative to the outer frame 2;

[0050] A lifting platform 4 is fixed on the inner frame 3; and

[0051] A driving assembly 6, used to drive the inner frame 3 to move up and down;

[0052] At least two lifting units 100 can be used in a synchronous lifting manner; in the two lifting units 100 that can be used in a synchronous lifting manner, the corresponding sides of the two fixing frames 1 form an opening structure, and the two lifting platforms 4 are arranged side by side and the clearance is matched (see Figure 1 and 2 ), or, a table 5 is fixedly connected between the two lifting platforms 4 (see Figure 4 ).

[0053] like Figure 1 and 2 As shown, the design of the opening structure enables the two lifting platforms 4 in the two lifting units 100 that can be lifted and lowered synchronously to have clearance fit, and the distance between the two lifting platforms 4 is smaller than when no opening structure is formed. The clearance fit mentioned in this application also includes the case where the clearance is 0.

[0054] like Figure 4 As shown, the design of the opening structure enables two lifting units 100 that can be lifted and lowered synchronously, and a table plate 5 can be fixedly connected between the two lifting platforms 4, so that the table plate 5 can be lifted and lowered synchronously with the two lifting platforms 4 without interfering with the fixed frame 1.

[0055] The ability to be raised and lowered synchronously mentioned in this application means that they can be used synchronously, but in actual use, you can choose not to be synchronized as needed, which enriches the entire usage scenario.

[0056] In this embodiment, the outer frame 2 is formed by splicing aluminum alloy, and the inner frame 3 is formed by splicing aluminum alloy. The use of aluminum alloy splicing has a simple structure and high space utilization.

[0057] like Figure 3 As shown, in this embodiment, the outer frame 2 is provided with a guide groove 21, the inner frame 3 is provided with a sliding protrusion 31 matching the guide groove 21, and the sliding protrusion 31 is located in the guide groove 21. In other embodiments, it can also be arranged as follows: the inner frame 3 is provided with a guide groove 21, the outer frame 2 is provided with a sliding protrusion 31 matching the guide groove 21, and the sliding protrusion 31 is located in the guide groove 21.

[0058] The cooperation between the sliding protrusion 31 and the guide groove 21 makes the lifting platform 4 more stable when moving up and down.

[0060] The winding motor 61 is mounted on the fixed frame 1;

[0061] The sprocket 62 is rotatably mounted above the fixed frame 1;

[0062] One end of the chain 63 is connected to the inner frame 3, and the other end is connected to the winding motor 61 after passing through the sprocket 62. When the winding motor 61 rotates, it can drive the inner frame 3 to move up and down.

[0063] In other embodiments, the driving component 6 can also be an electric push rod or a hydraulic cylinder. When it is an electric push rod or a hydraulic cylinder, the driving component 6 is installed on the fixed frame 1, and the movable rod of the driving component 6 is connected to the inner frame 3.

[0064] like Figure 5 As shown, in this embodiment, the bottom of the fixing frame 1 has a roller 7 and a support plate assembly 8 , and the support plate assembly 8 includes a support screw 81 screwed on the fixing frame 1 and a plate body 82 located below the support screw 81 .

[0065] The support screw 81 is rotated to move the disc 82 upward without contacting the ground. At this time, the lifting unit 100 can be quickly moved by the roller 7, and after moving into position, the support screw 81 is rotated to make the disc 82 contact the ground to fix the lifting unit 100 relative to the ground.

[0066] The design of the roller 7 and the support plate assembly 8 allows the position of each lifting unit 100 to be adjusted quickly and conveniently as needed during actual use. For example, two lifting units 100 can be arranged side by side to achieve clearance fit between the two lifting platforms 4 (see FIG. Figure 1 and 2 ), for example, the lifting units 100 can be separated by a certain distance, and then the two lifting platforms 4 can be connected by the platform 5, so that the two lifting platforms 4 and the platform 5 form a whole plate and move up and down synchronously (see Figure 4 ).

[0067] like Figure 1 and 5 As shown, in this embodiment, it also includes a positioning screw 9, which is screwed on the fixing frame 1. The positioning screw 9 is used to cooperate with the positioning point 200 on the ground to limit the fixing frame 1. The design of the positioning screw 9 can achieve precise positioning, ensuring that the lifting unit 100 moves to the set position and is limited. The design of the positioning screw 9, the roller 7 and the support plate assembly 8 can enable the lifting unit 100 to adjust the position quickly and accurately.

[0068] The above description is only a preferred embodiment of the utility model, and does not limit the patent protection scope of the utility model. Any equivalent structural transformation made using the contents of the utility model specification and drawings, directly or indirectly used in other related technical fields, is also included in the protection scope of the utility model.
