Description

Technical Field

[0001] The utility model relates to the technical field of RFID readers and writers, in particular to a handheld RFID reader and writer. Background Art

[0002] An RFID reader is a wireless device that "talks" to RFID tags, reading and writing information from them. It doesn't require direct contact with the tag; it simply needs to be within range. RFID readers are particularly useful in warehouses, supermarkets, and access control systems, enabling quick and accurate identification of goods, employee ID cards, and animal tags, improving both efficiency and safety.

[0003] Most existing RFID readers can be connected to the RFID reader through a handheld handle when in use. However, the RFID reader is mostly fixed to the handheld handle, which is inconvenient to disassemble and install. During the carrying process, the fixed handheld handle takes up a lot of space and has poor performance. Therefore, we propose a handheld RFID reader. Utility Model Content

[0004] The purpose of the present invention is to provide a handheld RFID reader / writer to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A handheld RFID reader / writer includes an RFID reader / writer body and a fixing rod. The rear end face of the RFID reader / writer body is fixedly connected to a fixing base, and a circular connecting groove is opened in the middle of the inner cavity of the fixing base. The bottom end of the circular connecting groove passes through the bottom wall of the fixing base, and a telescopic rod is vertically connected in the circular connecting groove. The telescopic rod is vertically slidably connected to the inner cavity of the fixing rod. A handle is installed on the rear side wall of the fixing rod. Both side walls of the top of the telescopic rod are opened with a clamping hole, and both ends of the inner cavity of the fixing base are provided with a disassembly and assembly component for fixing the clamping hole.

[0007] Furthermore: a plurality of groups of threaded positioning holes are provided on the rear outer wall of the telescopic rod, and locking bolts adapted to the threaded positioning holes are threadedly connected to the fixing rod.

[0008] Furthermore: the disassembly and assembly component includes an operating rod that is laterally slidably connected to the side wall of the fixing seat, and a clamping block that is adapted to the clamping hole is installed at one end of the operating rod close to the circular connecting groove.

[0009] Furthermore: the outer wall of the operating rod is connected to a movable slide, and the movable slide is slidably connected to the inner wall of the fixed seat. The outer wall of the operating rod is covered with a compression spring, and the compression spring is located between the outer side surface of the movable slide and the inner wall of the fixed seat.

[0010] Furthermore, one end of the operating rod away from the clamping block passes through the outer wall of the fixing seat, and the other end of the operating rod away from the clamping block is connected to a pull ring.

[0011] Furthermore: the hand-held end of the grip is covered with a non-slip rubber sleeve.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The RFID reader of the present invention is connected to the fixed rod and the telescopic rod through the fixing base, and with the function of the grip, the RFID reader is handheld. The height position of the RFID reader can be adjusted by the sliding connection between the fixing rod and the telescopic rod, which facilitates the use of the RFID reader. The clamping block can be connected to or disconnected from the clamping hole by the lateral sliding of two sets of operating pull rods on the disassembly and assembly parts and the elasticity of the compression spring, thereby realizing the rapid disassembly and assembly of the fixing base and the fixing rod and the telescopic rod, which facilitates the disassembly and installation of the RFID reader. After disassembly, the RFID reader occupies a small space, has good portability, and has a good use effect. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Example 1:

[0020] See also Figure 1-3The utility model provides a technical solution: a handheld RFID reader / writer, including an RFID reader / writer body 1 and a fixing rod 2, the rear end face of the RFID reader / writer body 1 is fixedly connected to a fixing base 7, and a circular connecting groove 8 is opened in the middle of the inner cavity of the fixing base 7, the bottom end of the circular connecting groove 8 passes through the bottom wall of the fixing base 7, and a telescopic rod 3 is vertically connected in the circular connecting groove 8, the telescopic rod 3 is vertically slidably connected to the inner cavity of the fixing rod 2, a handle 4 is installed on the rear side wall of the fixing rod 2, and a clamping hole 14 is opened on both side walls of the top of the telescopic rod 3, and a disassembly and assembly component for fixing the clamping hole 14 is provided at both ends of the inner cavity of the fixing base 7.

[0021] The RFID reader body 1 is an existing device, and the specific model and working principle are not described here. The fixing seat 7 is fixedly connected to the RFID reader body 1, and the fixing rod 2 is fixedly connected to the handle 4. The RFID reader body 1 is connected to the fixing rod 2 and the telescopic rod 3 through the fixing seat 7. With the function of the handle 4, the RFID reader body 1 is handheld. The height position of the RFID reader body 1 can be adjusted through the sliding connection between the fixing rod 2 and the telescopic rod 3, which is convenient for the use of the RFID reader body 1. The top of the telescopic rod 3 can be connected to the circular connecting groove 8. With the function of the disassembly and assembly parts, the card block 13 can be connected or disconnected from the card hole 14, realizing the rapid disassembly and assembly of the fixing seat 7 and the fixing rod 2 and the telescopic rod 3, which can facilitate the disassembly and installation of the RFID reader. After disassembly (after the telescopic rod 3 and the fixed rod 2 are disassembled), the RFID reader occupies a small space, has good portability, and has good use effect.

[0022] Among them, preferably, multiple groups of threaded positioning holes 5 are opened on the rear outer wall of the telescopic rod 3, and the fixed rod 2 is threadedly connected with a locking bolt 6 that is compatible with the threaded positioning hole 5; through the action of the locking bolt 6, the locking bolt 6 can be connected with the corresponding threaded positioning hole 5, and after the fixed rod 2 and the telescopic rod 3 are slid and adjusted to a certain height, the position of the telescopic rod 3 and the fixed rod 2 can be fixed.

[0023] Preferably, the disassembly and assembly components include an operating rod 9 that is laterally slidably connected to the side wall of the fixing seat 7, and a clamping block 13 that is adapted to the clamping hole 14 is installed at one end of the operating rod 9 close to the circular connecting groove 8; the operating rod 9 is fixedly connected to the clamping block 13.
