DETAILED DESCRIPTION

[0017] In order to make the technical solution and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0018] like Figure 1 As shown, a multi-station I-shaped frame of a lifting table includes at least two connecting cross bars 3 and a connecting longitudinal bar 4 for detachably connecting the two connecting cross bars 3. The two connecting cross bars 3 are connected by the connecting longitudinal bar 4 so that the two connecting cross bars 3 and the connecting longitudinal bar 4 connected to each other form an I-shaped structure, thereby achieving the purpose of high structural strength. It should be noted that the supporting vertical rods 1 are detachably connected at both ends of the connecting cross bars 3, and a panel connecting part 2 is provided at the top of the supporting vertical rod 1. The panel connecting part 2 serves the purpose of installing and fixing the table board. Among them, an assembly matching unit 5 is provided between the connecting longitudinal bar 4 and the connecting cross bar 3 and between the connecting cross bar 3 and the supporting vertical rod 1. The assembly matching unit 5 is installed and fixed between the connecting cross bars 3 and the supporting vertical rod 1 for connecting to each other or between the connecting cross bars 3 and the connecting longitudinal bar 4, thereby significantly reducing the difficulty of matching, installing and fixing the multi-station I-shaped frame of the lifting table.

[0019] like Figure 2 , Figure 3 As shown, the bottom of the support pole 1 is hollow and is used to connect the lifting drive or lifting limiter. The lifting drive is a linear drive composed of a cylinder, an oil cylinder or a threaded screw. This achieves the purpose of reducing the difficulty of assembly and pairing to achieve the lifting function. The lifting limiter is used to cooperate with the lifting drive to achieve the purpose of improving the stable lifting of the table top. In the embodiment of the present application, the lifting limiter adopts a telescopic rod, which is not described here.

[0020] It should be noted that the assembly matching unit 5 includes a connection block 51 for fixing on the supporting upright 1 or the connecting cross bar 3 and an anti-slip rod 52 inserted and fixed in the connecting cross bar 3 or the connecting longitudinal rod 4. The anti-slip rod 52 is connected with the corresponding connection block 51 and is used to prevent the corresponding connecting longitudinal rod 4 from being separated from the connecting cross bar 3 or the connecting cross bar 3 from being separated from the supporting upright 1. Therefore, when installing and fixing, the corresponding connecting longitudinal rod 4 is first staggered with the connecting cross bar 3 or the connecting cross bar 3 is staggered with the supporting upright 1, and then the anti-slip rod 52 is connected with the corresponding connection block 51 by utilizing the dislocation through the relative position movement. Among them, the connection block 51 includes a connection back plate 511 for connecting and fixing with the corresponding supporting upright 1 or the connecting cross bar 3 and an anti-slip hook 513 located at the upper end or the lower end of the connection back plate 511. A matching groove 514 is formed between the anti-drop hook 513 and the outer side wall of the corresponding supporting vertical rod 1 or connecting cross bar 3, and the anti-drop rod 52 is used to be inserted into the corresponding matching groove 514 from top to bottom or from bottom to top. Therefore, the difficulty of matching between the anti-drop rod 52 and the matching groove 514 is significantly reduced during matching and installation.

[0021] It should be mentioned that in the embodiment of the present application, the anti-slip hook 513 is located at the upper end of the connecting back plate 511, and the lower end of the connecting back plate 511 is provided with an abutting bottom plate 512. The connecting cross bar 3 or the connecting longitudinal bar 4 is provided with a connecting threaded hole 31, and the connecting threaded hole 31 is threadedly connected with an abutting bolt 53 whose upper end abuts against the abutting bottom plate 512, so that the connecting longitudinal bar 4 and the connecting cross bar 3 or the connecting cross bar 3 and the supporting vertical bar 1 in the lifting table multi-station I-shaped frame are connected to each other in combination with the grounding bolt and the abutting bottom plate 512, and the anti-slip rod 52 and the anti-slip hook 513, so as to effectively prevent the corresponding connecting longitudinal bar 4 and the connecting cross bar 3 or the connecting cross bar 3 and the supporting vertical bar 1 from separating from each other. At the same time, in order to reduce the difficulty of installing the assembly and matching unit 5, the connecting back plate 511 is welded and fixed to the outer wall of the corresponding supporting upright 1 or the connecting cross bar 3 or is fixed by inserting bolts and threads. Therefore, when the length of the multi-station I-frame of the lifting table is adjusted according to needs, the corresponding assembly and matching unit 5 can be installed and fixed on the extended and increased supporting upright 1, connecting cross bar 3 and connecting longitudinal bar 4, and when it is reduced, the assembly and matching unit 5 can be removed from the corresponding supporting upright 1, connecting cross bar 3 and connecting longitudinal bar 4.

[0022] In summary, the present application provides a multi-station I-frame of a lifting table, which is installed and fixed between a connecting crossbar 3 and a supporting vertical bar 1 or between a connecting crossbar 3 and a connecting longitudinal bar 4 for mutual connection through an assembly matching unit 5, thereby significantly reducing the difficulty of matching, installing and fixing the multi-station I-frame of the lifting table, and the I-shaped structure formed by the connecting crossbar 3 and the connecting longitudinal bar 4 significantly improves the structural strength of the multi-station I-frame of the lifting table, and when extending the multi-station I-frame of the lifting table, the assembly matching unit 5 is installed on the supporting vertical bar 1, the connecting crossbar 3 and the connecting longitudinal bar 4 added as needed, so that the extended part can be assembled and installed efficiently and stably, so that the multi-station I-frame of the lifting table has the effect of reducing the difficulty of assembly and extension.
