Connecting holes are provided at the upper and lower ends of the connector for connecting to objects on the upper and lower sides of the base connector respectively, thereby achieving a good upper and lower connection effect.

[0003] The bottom connection hole of the traditional base connector is located on the bottom plate, and the bottom plate is welded to the connection column. At present, the selected connection column is in fit with the side wall of the bottom plate, and the connection between the bottom plate and the connection column is completely welded, so the welding operation has a large workload and low work efficiency. Utility Model Content

[0004] In order to simplify the welding operation between the base plate and the connecting column and improve the welding work efficiency, the present application provides a base connecting piece.

[0005] The present application provides a base connector adopting the following technical solution:

[0006] A base connector comprises a base plate, a connecting column and a connecting plate, wherein the connecting plate is connected to the upper end of the connecting column, the base plate is connected to the lower end of the connecting column, the cross-section of the connecting column is U-shaped, there is a gap between the outer wall of the base plate and the inner wall of the connecting column, and the base plate and the inner wall of the connecting column are connected by spot welding.

[0007] By adopting the above technical solution, the cross-section of the connecting column is U-shaped, and the bottom plate is located on the inner side of the connecting plate, which reduces the possibility of the base being damaged by impact from foreign objects. The bottom plate and the connecting column are fixedly connected by spot welding, which simplifies the welding operation between the bottom plate and the connecting column and improves the work efficiency of the welding of the base connector.

[0008] Preferably, the connecting plate and the connecting column are integrally stamped.

[0009] By adopting the above technical solution, the connecting plate and the connecting column are formed by stamping, and the connecting plate and the connecting column are integrated, thereby reducing the possibility of the connection between the connecting plate and the connecting column being broken by external force.

[0010] Preferably, the upper end of the bottom plate is connected to a reinforcing rib, and the reinforcing rib is in contact with the inner wall of the connecting column.

[0011] By adopting the above technical solution, reinforcing ribs are provided on the bottom plate, and the reinforcing ribs abut against the inner wall of the connecting column, thereby improving the structural strength of the connection between the bottom plate and the connecting column, thereby improving the structural strength of the base connecting piece and increasing the service life of the base connecting piece.

[0012] Preferably, a groove is provided on one side of the reinforcing rib close to the inner wall of the connecting column, a protrusion is connected to the inner wall of the connecting column, the protrusion is embedded in the groove, and the side wall of the protrusion is in contact with the groove wall.

[0013] By adopting the above technical solution, a protrusion is connected to the inner wall of the connecting column, and the protrusion is located in the groove. When the base plate is subjected to external force along the length direction of the connecting column, the protrusion abuts against the groove wall, dispersing the stress at the connection between the base plate and the connecting column, reducing the possibility of fracture between the base plate and the connecting column, and improving the service life of the base connector.

[0016] Preferably, it further comprises an anti-skid pad, wherein the anti-skid pad is connected to a side of the bottom plate away from the connecting plate.

[0017] By adopting the above technical solution, an anti-skid pad is provided, and the anti-skid pad is connected to the bottom of the base plate. The anti-skid pad contacts the ground below, thereby increasing the friction between the base connector and the ground, reducing the possibility of wear of the base connector during movement, and increasing the service life of the base connector.

[0018] Preferably, the bottom plate is provided with a mounting hole, the anti-slip pad comprises a support block and a mounting column, the mounting column is connected to a side of the support block close to the bottom plate, and the mounting column is embedded in the mounting hole.

[0019] By adopting the above technical solution, the mounting column is embedded in the mounting hole, so that the anti-slip pad and the bottom plate are relatively fixed in the radial direction.

[0020] Preferably, the mounting post is interference fit with the mounting hole.

[0021] By adopting the above technical solution, the mounting column and the mounting hole are interference fit, which improves the stability of the connection between the anti-skid pad and the base plate and reduces the possibility of the anti-skid pad falling when the base connector is lifted.

[0022] Preferably, a rounded corner is provided on the outer periphery of one end of the mounting column away from the supporting block, and the rounded corner is used to abut against the wall of the mounting hole.

[0023] By adopting the above technical solution, a rounded corner is set, and the rounded corner abuts against the wall of the installation hole, which guides the installation column, makes it easier for the installation column to be embedded in the installation hole, and improves the installation efficiency of the anti-slip mat.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. The cross section of the connecting column is U-shaped, and the bottom plate is located inside the connecting plate, which reduces the possibility of the base being damaged by foreign objects.

[0026] 2. The connecting plate and the connecting column are formed by stamping, and the connecting plate and the connecting column are integrated, which reduces the possibility of the connection between the connecting plate and the connecting column being broken by external force;

[0027] 3. Set up an anti-skid pad, which is connected to the bottom of the base plate. The anti-skid pad contacts the ground below, thereby increasing the friction between the base connector and the ground, reducing the possibility of wear of the base connector during movement, and increasing the service life of the base connector.
