Description

Technical Field

[0001] The utility model relates to the technical field of RFID radio frequency identification antennas, in particular to an underground antenna for RFID radio frequency identification. Background Art

[0002] RFID technology is mainly divided into three parts: reader, antenna and tag. The reader sends out an electronic signal through the antenna. After receiving the electronic signal, the tag transmits the identification information stored on the back. The reader then receives and identifies the information sent back by the tag through the antenna. It is often used in logistics warehousing, access control, fixed asset management, security inspection, retail, public transportation and other fields. RFID radio frequency identification antennas are mainly installed on walls, ceilings, under floors or on door frames. As the name suggests, underground antennas are antennas installed under the ground, and the antennas are hidden and more beautiful.

[0003] When existing RFID underground antennas are used in logistics warehousing, trucks or forklifts often pass over the top of the RFID underground antennas. Although the antennas are buried under the floor or floor, the underground antennas will still be subject to certain pressure when vehicles pass by. Especially when forklifts are carrying heavy objects, the underground antennas are prone to breakage over time. If installed on the ground or suspended under the ceiling, the forklift's driving field of view is more likely to be bumped. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide an underground antenna for RFID radio frequency identification to solve the technical problems mentioned in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an underground antenna for RFID radio frequency identification, comprising an antenna body, a buffer pad connected to the top of the antenna body, and a first crossbeam and a second crossbeam connected to the top of the buffer pad respectively, both sides of the outer surface of the first crossbeam are connected to columns, and two reinforcing tubes are fixed inside the first crossbeam, the second crossbeam and the column.

[0006] By adopting the above technical solution, most of the pressure above the antenna body is transferred to the ground at the bottom of the antenna body through the arrangement of the first crossbeam, the second crossbeam and the column, thereby effectively reducing the pressure on the antenna body. At the same time, the first crossbeam, the second crossbeam and the column are flexibly connected to the antenna body through the buffer pad, thereby reducing the pressure transmitted to the antenna body by the first crossbeam, the second crossbeam and the column, and the structural strength of the first crossbeam, the second crossbeam and the column is further increased by the arrangement of the reinforcing tube.

[0007] Furthermore, the first cross beam is trapezoidal, and the column is L-shaped.

[0008] By adopting the above technical solution, the first cross beam is shaped so that its two sides can transfer the pressure from above to the ground below, and the same is true for the L-shaped column.

[0009] Furthermore, two of the first cross beams and two of the second cross beams are provided, and the two first cross beams are vertically distributed with respect to the two second cross beams.

[0010] By adopting the above technical solution, when a forklift or truck carrying heavy objects passes by, most of the pressure above the antenna body is transferred to the ground at the bottom of the antenna body through the arrangement of the first beam, the second beam and the column, thereby effectively reducing the pressure on the antenna body.

[0011] Furthermore, there are four columns, and the four columns are mirror-imaged.

[0012] By adopting the above technical solution, four columns are provided to increase the support points, so that most of the pressure from above is transferred to the ground at the bottom of the antenna body, thereby effectively reducing the pressure on the antenna body.

[0013] Furthermore, a connector is installed on one side of the antenna body.

[0014] By adopting the above technical solution, the staff connects the feeder to the connector to connect the antenna body to the external reader. The reader sends an electronic signal through the antenna body. After receiving the electronic signal, the tag transmits the identification information stored on the back. The reader then receives and identifies the information sent back by the tag through the antenna body.

[0015] Furthermore, a pressure plate is fixed between two of the columns, and the pressure plate is located on the outer surface of the antenna body. A slot is provided on the top of the pressure plate. A distribution plate is fixed between the other two columns, and the distribution plate is located on the back of the antenna body. An insert block and a pull plate are respectively connected to the bottom of the distribution plate.

[0016] By adopting the above technical solution, if the span of the warehouse door is large and a single underground antenna cannot accommodate it, the staff can put in several more underground antennas, so that the plug in one underground antenna is inserted into the slot in other underground antennas, so that the multiple underground antenna ports are overlapped together and difficult to separate laterally. When a forklift or truck carrying heavy objects passes by, the buried antenna under pressure transfers part of the pressure to the pressure plates of other buried antennas through the distributing plate, so that the first beams, second beams and columns of other buried antennas provide auxiliary support, further increasing the compressive resistance of the structure, and increasing the structural strength of the distributing plate by pulling the plate, reducing the occurrence of bending and deformation of the distributing plate after being compressed.

[0017] Furthermore, the plug block and the slot are both in a "T" shape, and the plug block is adapted to the slot.

[0018] By adopting the above technical solution, if the span of the warehouse door is large and a single underground antenna cannot accommodate it, the staff can put in several underground antennas, so that the plug in one underground antenna is inserted into the slot in other underground antennas, so that the multiple underground antenna ports are overlapped together and difficult to separate horizontally.

[0019] Furthermore, a plurality of the pull plates are provided, and the plurality of pull plates are equidistantly distributed, and the plurality of pull plates are all in a triangular shape.

[0020] By adopting the above technical solution, the structural strength of the distribution plate is increased by pulling the plate, and the occurrence of bending and deformation of the distribution plate after being compressed is reduced.

[0021] In summary, the utility model mainly has the following beneficial effects:

[0022] The utility model transmits most of the pressure above the antenna body to the ground at the bottom of the antenna body through the arrangement of the first crossbeam, the second crossbeam and the column, thereby effectively reducing the pressure on the antenna body. At the same time, the first crossbeam, the second crossbeam and the column are flexibly connected to the antenna body through the buffer pad, thereby reducing the pressure transmitted to the antenna body by the first crossbeam, the second crossbeam and the column, and further increasing the structural strength of the first crossbeam, the second crossbeam and the column through the arrangement of the reinforcement tube; effectively avoiding the crushing of the buried antenna by heavy objects when passing by, thereby extending the service life of the buried antenna.
