Description

The elevating mechanism Fastening device

This utility model relates to the operation table elevating mechanism.

The elevating mechanism of existing operation table as shown in Figure 1; Packing assembly 1 is directly to oppress these wear plates 4 with packing cylinder 4 walls with screw rod 2, but several packing assemblies 1 are arranged simultaneously when packing, can't make this packing assembly all have identical packing strength or adjust the strength of packing automatically, but because slide plate all around all will be adjusted very inconvenience, and the adjustment of packing strength is relatively more difficult, therefore can cause application of force inequality, the anti-wear component that adopts wear-resistant material is not to be best material, and add slide plate when packing assembly 1 and housing 5 are necessary after wearing and tearing, but its installing/dismounting is more non-easily.

The purpose of this utility model provides and a kind ofly can compensate anti-wear component automatically, and dismounting is easier elevating mechanism Fastening device again.

The purpose of this utility model is achieved in that the elevating mechanism Fastening device, it comprises: the housing of a pedestal, a rectangular hollow, the cylinder of a rectangular hollow and at least one packing assembly, housing is loaded on the pedestal, it is characterized in that: inner walls is provided with the packing hole, and is provided with screw in these packing holes; Lift component is housed on the pedestal, and lift component is positioned at enclosure interior, and a liftable axostylus axostyle is arranged; Cylinder is loaded on the lift component and is positioned at enclosure interior, and there is a circular hole on its top, and cylinder is driven lifting and is held by axostylus axostyle.

Above-mentioned design mainly is a plurality of distributions to be set on the mat housing and to be packing hole and the circular hole thereof that tandem is arranged, reached anti-wear component can be compensated automatically, and the easier again effect of dismounting.

Further specify again below by accompanying drawing, embodiment
