An energy-saving security rolling net power machine

Abstract

The invention discloses an energy-saving security net rolling power machine, which comprises a main body, a main rotating shaft rotatably connected to the top of the main body, a placement shaft located below the main rotating shaft, a connecting groove is opened on the surface of the main rotating shaft, and the inner cavity of the connecting groove is inserted into the A fixed bump is connected to the inner cavity of the main rotating shaft below the connecting groove, and a limiting groove is provided. Stoppers are fixedly connected to the top of the left and right side walls of the inner cavity of the limiting groove, and a rotating cavity is opened at the center of the inner cavity of the fixed bump. , the left and right side walls of the inner cavity of the fixed protrusion are provided with sliding grooves, the inner cavity of the sliding groove is slidably connected with a sliding block, and the center of the inner cavity surrounded by the stoppers on the left and right sides is threaded along its height direction There is a threaded screw rod, and a sliding block is slidably connected to the threaded screw rod located in the rotating cavity. The design structure of the present invention is reasonable, and can limit and fix the fixed protruding block. The fixed protruding block and the connecting groove are not easy to fall off. At the same time, the bolt can fix roller shafts of different sizes, and has a wide application range.

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
