This application uses a horizontal shock absorbing mechanism to balance the horizontal shock wave generated by the earthquake, and uses a vertical shock absorbing mechanism to balance the vertical shock wave generated by the earthquake, which can reduce the frequency and amplitude of the main body of the building shaking up and down or left and right, reduce the probability of the main body of the building collapsing, and improve the earthquake resistance. Effect.

The invention relates to transfer equipment, in particular to small cargo transfer equipment for warehousing service. The technical problem to be solved is to provide the small cargo transfer equipment for the warehousing service, which can adjust the width and the height and has a limiting effect. According to the technical scheme, the small cargo transfer equipment for the warehousing service comprises a connecting frame; two prismatic columns which are symmetrically arranged on one side of the top of the connecting frame; a lifting frame which is arranged between the prismatic columns in a sliding manner; first rotating shafts which are symmetrically and rotatably arranged on one side of the interior of the lifting frame; and a second rotating shaft which is rotatably arranged on one side of the bottom of the connecting frame. According to the size and height of goods, groove plates can be moved outwards, a first sliding plate and a second sliding plate can be moved upwards, and therefore the width between the groove plates and the height of the first sliding plate and the second sliding plate are adjusted, and the working efficiency of goods transferring by people is improved.
