Detailed Description

The present invention is described in further detail below with reference to the attached drawing figures.

Reference will now be made in detail to embodiments of the present patent, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present patent and are not to be construed as limiting the present patent.

As shown in fig. 1, a connector includes: the connecting seat 1, the first lug plate 2 and the second lug plate 3; the connecting seat 1 is a concave-shaped bending piece and comprises a bottom plate 13, a first wing plate 11 and a second wing plate 12; the first wing plate 11 and the second wing plate 12 are vertically installed on one side of the bottom plate 13; the first lug plate 2 and the second lug plate 3 are vertically arranged at the other side of the bottom plate 13 and are at the opposite side of the first wing plate 11 and the second wing plate 12; the cross-sectional directions of the first ear plate 2 and the second ear plate 3 and the first wing plate 11 and the second wing plate 12 are perpendicular to each other; this is because in this embodiment, the installation direction of the cross tube 4 in the electric bed is also perpendicular to the installation direction of the tail stock of the motor. The size of the groove of the connecting seat 1 can accommodate the transverse tube 4 of the bed bottom of the electric bed, and mounting holes are arranged on the first wing plate 11 and the second wing plate 12; the distance between the first lug plate 2 and the second lug plate 3 can accommodate a tailstock 5 of a motor of an electric bed.

As shown in fig. 2 and 3, the center points of the first and

second mounting holes

14 and 15 pass through the center line of the cross section of the first and

second wing plates

11 and 12. The mounting hole is arranged in the middle, so that the connecting seat is stressed more uniformly when being connected with the transverse pipe, and local stress damage is not easy to cause; a third mounting hole 41 is formed at a corresponding position of the bed bottom transverse tube 4, so that the first mounting hole 14, the second mounting hole 15 and the third mounting hole 41 can be connected through a shaft pin. Further, a first through hole 21 and a second through hole 31 are arranged on the first ear plate 2 and the second ear plate 3; the corresponding position on the motor tailstock 5 is also provided with a third through hole 51, so that the first through hole 21, the second through hole 31 and the third through hole 51 can be connected through a shaft pin.
