Energy-saving security net rolling power machine

Abstract

The invention discloses an energy-saving security net rolling power machine. The energy-saving security net rolling power machine comprises a main body, a main rotating shaft rotationally connected with the top of the main body, and a placing shaft located below the main rotating shaft, a connecting groove is formed in the surface of the main rotating shaft, a fixed protruding block is inserted into an inner cavity of the connecting groove, a limiting groove is formed in the inner cavity of the main rotating shaft below the connecting groove, and the tops of the left side wall and the right side wall of the inner cavity of the limiting groove are fixedly connected with stop blocks; and a rotating cavity is formed in the center of an inner cavity of the fixed protruding block, sliding grooves are formed in the left side wall and the right side wall of the inner cavity of the fixed protruding block, inner cavities of the sliding grooves are in sliding connection with sliding blocks, and threaded lead screws are in threaded connection with the centers of inner cavities of stop blocks in the height direction of the stop blocks; according to the energy-saving security net rolling power machine, the design structure is reasonable, the fixed protruding block can be limited and fixed, the fixed protruding block and the connecting groove are not easy to disengage and fall off, meanwhile, bolts can fix roll shafts of different sizes, and the use range is large.

Description

technical field [0001] The invention relates to the technical field of power machines, in particular to an energy-saving security net rolling power machine. Background technique [0002] The net roll power machine refers to the machine that converts the electric energy into force to lift and close the roll net. It is generally suitable for shopping malls, theaters and other places. The output form of the power machine is usually rotation. The power machine is a kind of machine that can turn other forms Machines that can be converted into mechanical energy, including internal combustion engines, gasoline-powered engines, etc., external combustion engines, Stirling power engines, steam engines, etc., electric motors, etc. [0003] The existing patent No. CN 108046066 A discloses an energy-saving security net rolling power machine, which includes a main cover plate of the net rolling power machine and a fixed raised block. The bottom end of the main cover plate of the net rolli...

Problems solved by technology

[0003] The existing patent No. CN 108046066 A discloses an energy-saving security net rolling power machine, which includes a main cover plate of the net rolling power machine and a fixed raised block. The bottom end of the main cover plate of the net rolling power machine is provided with a net rolling power machine The main drive shaft, the surface of the main drive shaft of the roll net power machine is provided with a connecting groove for the main drive shaft of the roll net power machine, and the fixed protrusion is installed inside the connection groove of the main drive shaft of the roll net power machine, and the roll net power machine places the shaft The bottom end of the net rolling power machine base is provided with; the main transmission shaft connection groove and the fixed protrusion of the net winding power machine designed in the present invention can be directly replaced when the main transmission shaft of the net winding power machine needs to be replaced or maintained. It is very convenient to use without welding connection. However, the applicant believes that the installation and disassembly of the fixed protruding block and the connecting groove of the net winding power machine in the above application are inconvenient, and the fixed protruding block cannot be limited and fixed. During the process, the fixed protruding block and the connecting groove are easy to separate, and the bolt can only fix the roller shaft of a fixed size, and the scope of use is small
