Abstract

The utility model relates to the technical field of operation equipment, in particular to a protection device at the bottom of a trampoline safety net, which comprises a trampoline main body, a protection assembly is arranged at the top of the trampoline main body, the protection assembly comprises six connecting columns, and the six connecting columns are sleeved in an inner cavity of the trampoline main body. The bottom of the surface of the connecting column is fixedly sleeved with a mounting plate, an inner cavity of the mounting plate is fixedly connected with the trampoline body through fixing bolts, and the bottom of the connecting column is in threaded connection with a fixing screw sleeve. When the connecting column needs to be fixed to the trampoline body, firstly, the connecting column is inserted into the trampoline body, then the connecting column is preliminarily fixed to the trampoline body through the mounting plate and the fixing bolt, then the bottom of the connecting column is sleeved with the fixing thread sleeve, at the moment, the rotating plate is rotated, the fixing thread sleeve is driven by the rotating plate to rotate, and then the connecting column is fixed to the trampoline body. When the top of the fixing screw sleeve is in contact with the bottom of the trampoline main body, the connecting column can be secondarily fixed.
