Handheld automatic flag raising and lowering device

Abstract

The invention relates to a handheld automatic flag raising and lowering device. The handheld automatic flag raising and lowering device comprises an improved flag raising and lowering crank and is characterized in that the tail end of a rolling sleeve joint is manufactured into a prism with at least 3 sides, and the prism is concentric to a rolling sleeve and can be mounted a handheld electric rolling device; the handheld electric rolling device achieves the functions of forward and backward rotation, speed regulation, starting and stopping, and operating time setting. The handheld automatic flag raising and lowering device is powered by dry batteries or lithium batteries to save an external alternate current power supply; the rolling sleeve joint can be transformed from an original manualflag raising and lowering crank. A user can hold the handheld automatic flag raising and lowering device by hands to stably control the time and speed of flag raising and lowering and meanwhile to reduce the labor intensity.

Description

technical field [0001] The invention relates to the technical field of flag raising and lowering devices, and is an improved method of a manual handle for raising and lowering flags, thereby improving the accuracy of the flag raising and lowering process and reducing labor intensity. Background technique [0002] For the driving method of raising and lowering the flag, there are two commonly used methods. [0003] One method is to manually raise and lower the flag with a handle, which is less difficult to manufacture, cheaper in price, and simple in management. It is difficult to control the time, and the process of raising and lowering the flag may be difficult to complete due to misoperation, which reduces the solemnity of the raising and lowering process. [0004] A kind of method is to use electric motor to drive lifting flag, for example CN107386772A discloses including base, power supply, motor mount, two-way motor, motor controller, stay rope, flag support rod, flag,...

[0003] One method is to manually raise and lower the flag with a handle, which is less difficult to manufacture, cheaper in price, and simple in management. It is difficult to control the time, and the process of raising and lowering the flag may be difficult to complete due to misoperation, which reduces the solemnity of the flag raising process

[0004] A kind of method is to use electric motor to drive lifting flag, for example CN107386772A discloses including base, power supply, motor mount, two-way motor, motor controller, stay rope, flag support rod, flag, fixed pulley, connecting rod, flagpole, display screen, Control keys and switches, a flagpole is installed in the middle of the base, a power supply and a motor mounting seat are installed on one side of the base, a two-way motor is installed on the motor mounting seat, the two-way motor is electrically connected to the power supply, and a motor controller is installed on the two-way motor. The device is electrically connected with the two-way motor. There is a connecting rod on the upper end of the flagpole, and a fixed pulley is installed on one end of the connecting rod. On the motor shaft at the other end of the two-way motor, a flag support rod is set on the pull rope, and a flag is arranged on the flag support rod. The two-way motor is connected with the motor controller to control the speed of the two-way motor, so that the flag rises at a uniform speed, and the operation It is simple and has powerful additional functions, but it is difficult and expensive to maintain and maintain. The installation and maintenance cost is much higher than that of the manual flag raising system
