Label printing device with short circuit prevention function

Abstract

The invention relates to a label printing device with a short circuit prevention function. The label printing device comprises a main body, an electrifying mechanism and a protection mechanism, the electrifying mechanism is arranged on the main body, the protection mechanism is arranged on the electrifying mechanism, the electrifying mechanism comprises an electrifying assembly, a connecting assembly and a protection assembly, the protection mechanism comprises a fixing ring, a protection cover and a limiting assembly, and an alarm unit is arranged on a plug. According to the label printing device with the short circuit prevention function, energization of the main body is achieved through the electrifying mechanism, the electrifying mechanism is protected through the protection mechanism, label printing is achieved through the main body, the electrifying mechanism monitors the temperature online through the protection assembly, so that the short circuit problem can be found in time, the situation of fire caused by short circuit is avoided, the mechanism adopts a pure mechanical structure, the use of devices such as a temperature sensor is avoided, the stability is improved, the service life is prolonged, and meanwhile, the device realizes better early warning and short circuit prevention effects by quickly popping up the plug and warning of the alarm unit.

Description

technical field [0001] The invention relates to a label printing device with the function of preventing short circuit. Background technique [0002] Various types of labels are required in offices, factories, warehouses, and shopping malls, such as when purchasing clothing, hang tags on clothing, train tickets, boarding passes, luggage tags, labels for goods in stores, etc. When printing this type of label, label printing equipment is generally used. The existing label printing equipment includes label printers, etc. The label printer refers to that it does not need to be connected to a computer. The printer itself carries an input keyboard or an intelligent touch screen for operation. Font library and a considerable number of label template formats, through the LCD screen of the body, you can directly input, edit, and typeset label content according to your own needs, and then directly print out the printer. [0003] The existing label printing devices are generally driven...

Problems solved by technology

[0003] The existing label printing devices are generally driven by electric energy. When connecting the circuit, the plug is generally inserted into the socket for powering on. However, the socket and the plug are generally not equipped with a good protection mechanism. Once dust and water vapor accumulate, it is easy to cause damage. Short circuit, short circuit will cause the electrified part to become hot, and even cause a fire, causing serious economic and property losses
