Description

Technical Field

[0001] This utility model relates to the field of RFID handheld terminal technology, and more specifically, to an RFID handheld terminal with protective functions. Background Technology

[0002] An RFID handheld terminal is a portable data acquisition device with radio frequency identification (RFID) function. It is widely used in logistics, warehousing, retail, medical care, transportation and other fields. The RFID handheld terminal transmits data to the RFID tag in a non-contact manner through radio frequency signals. When the handheld terminal is close to the RFID tag, its built-in antenna will emit radio frequency signals to activate the tag and establish a communication link with it. After receiving the signal, the tag will return the stored information to the handheld terminal through radio frequency signals. The handheld terminal will then decode, process and display this information.

[0003] Most existing handheld terminals are easily dropped during use because they are held by hand. They are also prone to collisions during transport, which can damage the display screen and corners, affecting normal operation and reducing the lifespan of the smart terminal. Therefore, a protective RFID handheld terminal is proposed. Utility Model Content

[0015] 1. This utility model firstly enhances the anti-collision strength of the handheld terminal through the combination of the protective shell and end cap, and the buffer strip and buffer cavity can buffer when it is hit. At the same time, the reinforcing ribs improve the strength of the protective shell and end cap, prevent damage to the protective shell and end cap, and improve the use effect. The protective cover plate covers and protects the display surface of the handheld terminal. The combination of metal strip and magnetic strip limits the position of the protective cover plate and improves the protection effect.

[0016] 2. This utility model also facilitates the maintenance, installation, and use of the handheld terminal by separating and assembling the end cap and protective shell. The French side limits the installation position of the end cap through the cooperation of the first positioning strip and the first positioning slot, the second positioning slot and the second positioning strip. The installation position of the end cap can be fixed by inserting the screw through the second screw hole into the inside of the first screw hole, which improves the assembly strength. The connecting ring makes it easy to carry and prevents it from falling, thus improving the protection effect.
