[0021] 3. The lifting column mounting structure of the lifting table can prevent the deformation of the mounting bolts caused by the direct collision with the mounting bolts due to the excessive insertion of the connecting square tube during installation, through the setting of the protective plate. The deformation of the mounting bolts may cause jamming during subsequent disassembly. Therefore, the setting of the protective plate can separate the installation frame to ensure that the connecting square tube will be blocked by the protective plate when inserted and will not be inserted too deeply, thereby ensuring the service life of the mounting bolts and good use effect.

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0030] The present invention provides a lifting column installation structure for a lifting table. Figure 1-6As shown, it includes a column body 2, a mounting frame 4, a table top connecting arm 6, and a fixing bolt 7 for fixing the column body 2, the mounting frame 4 and the table top connecting arm 6 to each other. Mounting bolts 8 are provided on the front and back sides of the top of the column body 2. The mounting frame 4 is provided with a mounting groove 9 corresponding to the mounting bolt 8. The mounting groove 9 includes a horizontal portion and a vertical portion. The bottom end of the vertical portion extends to the bottom surface of the mounting frame 4, and one end of the horizontal portion is connected to the vertical portion.

[0031] By setting the mounting bolts 8 and mounting slots 9, during installation, it is only necessary to screw the mounting bolts 8 on the front and rear sides of the lifting column, then align the bottom opening of the vertical part of the mounting slot 9 on the mounting frame 4 with the mounting bolts 8 and move downward, and then push it sideways to make the mounting bolts 8 enter the horizontal part of the mounting slot 9. Because the horizontal part of the mounting slot 9 conflicts with the mounting bolts 8, the entire mounting frame 4 will not continue to fall, and then continue to push until the outer side surface of the lifting column and the mounting frame 4 fit together, and then place the table board connecting arm 6 on the welding frame, and use the fixing bolts 7 to fix the mounting frame 4, the lifting column and the table board connecting arm 6 to each other on the side to complete the installation. The operation is very simple and convenient, which greatly improves the installation efficiency.

[0032] The column body 2 is provided with a screw hole matching the mounting bolt 8 , and the mounting bolt 8 is threadedly engaged in the screw hole.

[0033] In some embodiments, as Figure 4 As shown, a cover shell 3 is provided on the top of the column body 2 , and mounting holes corresponding to the mounting bolts 8 are opened on the cover shell 3 , and the cover shell 3 and the column body 2 are fixedly connected by the mounting bolts 8 .

[0034] By providing the mounting holes on the cover shell 3 , the mounting bolts 8 can fix the cover shell 3 and the lifting column, making the installation more convenient.

[0035] There are two mounting bolts 8 on each side of the column body 2, and the mounting bolts 8 on both sides are symmetrically arranged.

[0036] It also includes a connecting square tube 5 for connecting two installation frames 4, and the connecting square tube 5 matches the installation frames 4.

[0037] In some embodiments, as Figure 2-3 As shown, a protective plate 10 is fixedly connected to one side of the installation groove 9 close to the connecting square tube 5, which is used to prevent the end of the connecting square tube 5 from colliding with the installation bolt 8 when the connecting square tube 5 is inserted.

[0038] The provision of the protective plate 10 can prevent the mounting bolt 8 from being deformed due to the connection square tube 5 being inserted too deeply and directly colliding with the mounting bolt 8 during installation. The deformation of the mounting bolt 8 may cause jamming during subsequent disassembly. Therefore, the provision of the protective plate 10 can separate the interior of the mounting frame 4, ensuring that the connection square tube 5 will be blocked by the protective plate 10 when inserted and will not be inserted too deeply, thereby ensuring the service life of the mounting bolt 8 and having a good use effect.

[0039] The bottom of the column body 2 is fixedly connected to the table leg 1.

[0040] One end of the transverse portion of the mounting groove 9 away from the vertical portion is configured in an arc shape.

[0041] Working principle: Through the setting of the mounting bolts 8 and the mounting slots 9, during installation, you only need to screw the mounting bolts 8 on the front and rear sides of the lifting column, and then align the bottom opening of the vertical part of the mounting slot 9 on the mounting frame 4 with the mounting bolts 8 and move downward, and then push it to the side so that the mounting bolts 8 enter the horizontal part of the mounting slot 9. Because the horizontal part of the mounting slot 9 and the mounting bolts 8 conflict with each other, the entire mounting frame 4 will not continue to fall, and then continue to push until the outer side surface of the lifting column and the mounting frame 4 fit together, and then place the table board connecting arm 6 on the welding frame, and use the fixing bolts 7 to fix the mounting frame 4, the lifting column and the table board connecting arm 6 to each other on the side to complete the installation. It is very simple and convenient to operate, which greatly improves the installation efficiency.

[0042] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
