DETAILED DESCRIPTION

[0018] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0019] Example:

[0020] like Figures 1 to 3 As shown, an elevator shaft includes a first shaft 1 and a second shaft 2, wherein the first shaft 1 is arranged above the second shaft 2, the first shaft 1 includes four first columns 3, and the second shaft 2 includes four second columns 4, the four first columns 3 correspond to the four second columns 4 in upper and lower directions, and each first column 3 is connected to the corresponding second column 4 through a connecting assembly 5; each connecting assembly 5 includes a first mounting plate 501, two second mounting plates 502, and a plug-in plate 503, and the first mounting plate 501 and the second column 4 are detachable. The two second mounting plates 502 are rotatably connected to the two sides of the first mounting plate 501, and after the two second mounting plates 502 are rotated, they fit into the side walls of the first column 3. The two second mounting plates 502 are provided with sliding grooves 6 on one side away from the first mounting plate 501. The plug-in plate 503 includes a main body 5031 and two plug-in parts 5032. The two plug-in parts 5032 are two vertical plates. The two plug-in parts 5032 correspond to the two sliding grooves 6 one by one. A locking piece is provided on the plug-in plate 503 for fixed connection with the first column 3.

[0021] By providing the connection assembly 5, namely a first mounting plate 501, two second mounting plates 502, a plug plate 503 (a main body 5031, two plug-in parts 5032 fixedly connected to the main body 5031), a sliding groove 6, and a locking piece, since the connection assembly 5 is detachably connected to the first shaft 1 and the second shaft 2, the provision of the connection assembly 5 can prevent the four first columns 3 from being placed above the four second columns 4. This is because the opening size limit of the connection assembly 5 makes it difficult to install the four second columns 4. If the installation of the four second columns 4 is relatively easy, the fit between the connection assembly 5 and the corresponding second columns 4 will not be tight enough, so shaking will occur between the first shaft 1 and the second shaft 2.

[0022] The first mounting plate 501 is attached to the second column 4 during installation, thereby laying the foundation for the installation of the connecting assembly 5, and then the second mounting plate 502 is rotated and the plug-in plate 503 is slid, so that the size of the opening of the connecting assembly 5 can be adjusted according to the size of the first column 3, so that the connecting assembly 5 is tightly attached to the first column 3, and finally the locking assembly is used to lock the connecting assembly 5. This locking method is more convenient and does not cause environmental pollution.

[0023] As shown in Figure 1 , the bottom end of the four first columns 3 is fixedly provided with a plug-in block 7, the top end of the four second columns 4 is provided with a plug-in slot 8, and the four plug-in blocks 7 correspond to the four plug-in slots 8. During installation, the plug-in block 7 is aligned with the plug-in slot 8 and is inserted into the plug-in slot 8, thereby positioning the first column 3 and forming the preliminary installation between the first column 3 and the second column 4, preventing the first shaft 1 and the second shaft 2 from shaking due to loose connection.

[0024] As shown in Figure 1 and Figure 2 , the second screw 9 is threadedly connected to each of the first mounting plates 501, and each of the second screws 9 is used to pass through the corresponding first mounting plate 501 and then pass into the corresponding second column 4. The second screw 9 is a specific locking method, which is a common locking method. The second screw 9 locks the connecting assembly 5 and the second column 4, which is convenient and has high firmness.

[0025] As shown in Figure 1 and Figure 2 , the locking member is a first screw 10, the first screw 10 is threadedly connected to the main body 5031, and the first screw 10 is used to pass through the main body 5031 and then pass into the first column 3. The first screw 10 is a specific locking member, which is a common locking method. The first screw 10 locks the connecting assembly 5 and the first column 3, which is convenient and has high firmness.

[0026] As shown in Figure 1 and Figure 2 , the third screw 11 is threadedly connected to each of the first mounting plates 501, and each of the third screws 11 is used to pass through the corresponding first mounting plate 501 and then pass into the corresponding first column 3. The third screw 11 is a specific locking method, which is a common locking method. The third screw 11 locks the connecting assembly 5 and the first column 3 twice, thereby strengthening the installation between the connecting assembly 5 and the first column 3.

[0027] As shown in Figures 1 to 3As shown, the two second mounting plates 502 are hinged to the two sides of the first mounting plate 501, and this hinging mode is a prior art, which specifically realizes the connection of the two second mounting plates 502 and the corresponding first mounting plate 501, so that the connecting assembly 5 can be flexibly separated from the first upright 3 after the connecting assembly 5 is separated from the sliding slot 6.

[0028] Working principle:

[0029] In use, the four insertion blocks 7 on the first shaft 1 are aligned with the four insertion slots 8 of the second shaft 2, and the four first uprights 3 are correspondingly inserted into the four second uprights 4.

[0030] Then four connecting assemblies 5 are taken, and the four first mounting plates 501 are sequentially attached to the four second uprights 4 and screwed into the second bolts 9, then the two second mounting plates 502 on each first mounting plate 501 are rotated, and the two second mounting plates 502 are attached to the two side walls of the corresponding first upright 3 after being rotated, at this time, the lower part of the first mounting plate 501 is attached to the second upright 4, and the upper part of the first mounting plate 501 is attached to the first upright 3, then the third bolt 11 is screwed in, then each insertion plate 503 is slid, so that the main body 5031 of each insertion plate 503 is attached to the corresponding first upright 3 in the corresponding sliding slot 6, and the first bolt 10 is screwed in, thereby each connecting assembly 5 is fixedly connected to the corresponding first upright 3, and the entire operation is completed.
