Description

Technical Field

[0001] The utility model relates to the technical field of RFID readers and writers, in particular to an industrial-grade split-type RFID reader and writer. Background Technique

[0002] Radio Frequency Identification (RFID) is an advanced automatic identification technology that can identify specific targets and read and write relevant data through radio signals without establishing mechanical or optical contact between the identification system and the specific target. RFID readers and writers are also divided into mobile and fixed types. At present, RFID technology is widely used, such as libraries, access control systems, food safety traceability, etc. In recent years, with the maturity of technical standards, the RFID industry has developed rapidly in various countries.

[0003] However, for existing RFID readers and writers, usually the reader and writer and the information processor are separate. The separate reader and writer only complete the identification and reading and writing operations, and often an additional processor needs to be configured. The two perform data transmission through an interface and a data cable. However, after long-term use of the data cable, the contact position with the connector is prone to looseness. At the same time, the connector position is also prone to water ingress and dust ingress, resulting in damage to the reader and writer and affecting its use. Content of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide an industrial-grade split-type RFID reader and writer to solve the technical problems in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: An industrial-grade split-type RFID reader and writer, including a reader and writer main body and an interface. A protective frame is connected to the outer surface of the reader and writer main body. A fixing plate is arranged above the inside of the protective frame. One side of the fixing plate is connected with a bidirectional lead screw. The outside of the bidirectional lead screw is connected with a threaded block and an adjusting wheel. The bottom of the threaded block is connected with a clamping plate. A spring is arranged inside the clamping plate. One end of the spring is connected with a protective plate. A first limit block is arranged on one side of the protective plate. A second limit block is arranged at the bottom of the clamping plate.

[0006] Further, mounting brackets are connected to both sides of the reader and writer main body. The number of the mounting brackets is two, and the two mounting brackets are symmetrically distributed.

[0007] By adopting the above technical solution, through the mounting brackets, the staff can fix the reader and writer main body at the required position with bolts for work.

[0008] Further, the mounting bracket is in an "L" shape, and round holes are opened at the top and bottom of the mounting bracket.

[0009] By adopting the above technical solution, by designing it in an "L" shape, while increasing the area of the mounting bracket, it can also protect both sides of the reader body, preventing the reader body from being damaged due to bumps. The bolts are positioned through the round holes, making the installation of the reader body more firm.

[0010] Furthermore, a limiting groove is provided below the interior of the protective frame, and the second limiting block is slidably connected to the limiting groove.

[0011] By adopting the above technical solution, through the cooperation of the provided limiting groove and the second limiting block, it prevents the clamping plate from rotating driven by the threaded block, restricting the traveling direction of the clamping plate, so that the clamping plate can only move horizontally on the protective frame.

[0012] Furthermore, a sliding groove is opened inside the clamping plate, and the protective plate and the first limiting block are slidably connected to the sliding groove.

[0013] By adopting the above technical solution, when the clamping plate is opened, the protective plate moves in the sliding groove under the elastic force of the spring and is limited by the first limiting block, preventing the protective plate from sliding out of the clamping plate and causing dislocation, which affects the practicality of the device.

[0014] Furthermore, two sets of the clamping plate, the protective plate, the threaded block, the spring, the first limiting block, the second limiting block, the sliding groove, the limiting groove and the fixing plate are provided, and the two sets of the clamping plate, the protective plate, the threaded block, the spring, the first limiting block, the second limiting block, the sliding groove, the limiting groove and the fixing plate are symmetrically distributed.

[0015] By adopting the above technical solution, when the interface is vacant, under the elastic force of the spring, the two protective plates tightly fit on the outer surface of the interface, preventing dust and water from entering. When a data cable needs to be installed, by rotating the adjusting wheel to drive the bidirectional lead screw to rotate, the threaded block drives the clamping plate to move outwards, so as to drive the protective plate to slide towards both sides in the sliding groove through the spring, open the interface and insert the data cable. When the data cable is installed, rotate the adjusting wheel to make the clamping plate clamp the data cable, preventing the data cable from loosening.

[0016] Furthermore, an interface is installed on one side of the outer surface of the reader body, and a data cable is connected inside the interface.

[0017] By adopting the above technical solution, through the connection of the interface and the data cable, it is convenient for the reader body to transmit data to the processor for processing.

[0018] Furthermore, a through hole is opened on the outer surface of the clamping plate, and the diameter of the through hole is equal to the diameter of the data cable.

[0019] By adopting the above technical solution, through the provided through hole, when the data cable is installed, the clamping plate clamps the data cable, preventing the data cable from loosening and avoiding affecting data transmission.

[0020] Furthermore, the outer surface of the adjusting wheel is provided with protrusions, and rubber pads are provided on one side of the guard plate and in the through holes, and the outer surface of the data cable is in contact with the rubber pads.

[0021] By adopting the above technical solution, through the protrusions, the friction between the surface of the adjusting wheel and the fingers is increased, so that the adjusting wheel can be rotated better. By providing the rubber pads, when the data cable is installed, the clamping plate and the guard plate are prevented from pinching the data cable.

[0022] Furthermore, both the guard plate and the clamping plate are made of PVC.

[0023] By adopting the above technical solution, PVC has the characteristics of light weight, good waterproof and moisture-proof properties, and at the same time, it is cheap, easy to manufacture and has low production cost, which can reduce the production cost.

[0024] In summary, the main beneficial effects of the present utility model are as follows:

[0033] Embodiment 1: An industrial-grade split RFID reader-writer, as Figures 1 - 4 shown, includes a reader-writer main body 1 and an interface 5. Mounting brackets 2 are connected to both sides of the reader-writer main body 1. The number of mounting brackets 2 is two, and the two mounting brackets 2 are symmetrically distributed. Through the mounting brackets 2, the staff can fix the reader-writer main body 1 at the required position with bolts for work. A protective frame 3 is connected to the outer surface of the reader-writer main body 1. Above the inside of the protective frame 3, there is a fixing plate 6. One side of the fixing plate 6 is connected with a bidirectional lead screw 7. The outside of the bidirectional lead screw 7 is connected with a threaded block 9 and an adjusting wheel 8. The bottom of the threaded block 9 is connected with a clamping plate 10. Inside the clamping plate 10, there is a spring 12. One end of the spring 12 is connected with a protective plate 11. Both the protective plate 11 and the clamping plate 10 are made of PVC. PVC has the characteristics of light weight, good waterproof and moisture-proof properties, and at the same time, it is cheap, easy to manufacture, and has low production costs, which can reduce production costs. One side of the protective plate 11 is provided with a first limit block 13, and the bottom of the clamping plate 10 is provided with a second limit block 14. An interface 5 is installed on one side of the outer surface of the reader-writer main body 1. A data line 4 is connected inside the interface 5. Through the connection between the interface 5 and the data line 4, it is convenient for the reader-writer main body 1 to transmit data to the processor for processing.

[0034] Refer to Figure 1 and Figure 2 , in the above embodiment, the mounting bracket 2 is in an "L" shape, and round holes are opened at the top and bottom of the mounting bracket 2. By designing it in an "L" shape, while increasing the area of the mounting bracket 2, it can also protect both sides of the reader-writer main body 1 to prevent the reader-writer main body 1 from being damaged due to knocking. Through the round holes, the bolts are positioned, making the installation of the reader-writer main body 1 more firm.

[0035] Refer to Figure 1 , in the above embodiment, a limit groove 16 is provided below the inside of the protective frame 3, and the second limit block 14 is slidably connected with the limit groove 16. By the cooperation of the opened limit groove 16 and the second limit block 14, it prevents the clamping plate 10 from rotating driven by the threaded block 9, restricts the advancing direction of the clamping plate 10, and makes the clamping plate 10 only move horizontally on the protective frame 3.

[0036] Refer to Figure 3 and Figure 4, in the above embodiment, a chute 15 is provided inside the clamping plate 10. The protective plate 11 and the first limiting block 13 are slidably connected to the chute 15. When the clamping plate 10 is opened, the protective plate 11 moves in the chute 15 under the elastic force of the spring 12 and is limited by the first limiting block 13 to prevent the protective plate 11 from sliding out of the clamping plate 10 and causing dislocation, which affects the practicality of the device.

[0037] Refer to Figures 1 - 4 , in the above embodiment, there are two sets of the clamping plate 10, the protective plate 11, the threaded block 9, the spring 12, the first limiting block 13, the second limiting block 14, the chute 15, the limiting groove 16 and the fixing plate 6 respectively. And the two sets of the clamping plate 10, the protective plate 11, the threaded block 9, the spring 12, the first limiting block 13, the second limiting block 14, the chute 15, the limiting groove 16 and the fixing plate 6 are symmetrically distributed. When the interface 5 is vacant, under the elastic force of the spring 12, the two protective plates 11 are tightly attached to the outer surface of the interface 5 to prevent dust and water from entering. When the data cable 4 needs to be installed, by rotating the adjusting wheel 8 to drive the bidirectional lead screw 7 to rotate, the threaded block 9 drives the clamping plate 10 to move outward, so as to drive the protective plate 11 to slide to both sides in the chute 15 through the spring 12, open the interface 5 and insert the data cable 4. After the data cable 4 is installed, rotate the adjusting wheel 8 to make the clamping plate 10 clamp the data cable 4 to prevent the data cable 4 from loosening.

[0038] Refer to Figures 1 - 4 , in the above embodiment, through holes are provided on the outer surface of the clamping plate 10, and the diameter of the through holes is equal to the diameter of the data cable 4. Through the provided through holes, after the data cable 4 is installed, the clamping plate 10 clamps the data cable 4 to prevent the data cable 4 from loosening and avoid affecting data transmission.

[0039] Refer to Figures 1 - 4 , in the above embodiment, rubber pads are provided on one side of the protective plate 11 and inside the through holes, and the outer surface of the data cable 4 is in contact with the rubber pads.

When the interface 5 is vacant, the two guard plates 11 are tightly attached to the outer surface of the interface 5 under the elastic force of the spring 12. When it is necessary to connect the data cable 4, the bidirectional lead screw 7 is rotated by turning the adjusting wheel 8, so that the threaded block 9 drives the clamping plate 10 to move outwards, thereby driving the second limit block 14 to move in the limit groove 16. At the same time, the spring 12 drives the guard plate 11 to slide towards both sides in the sliding groove 15. At this time, the interface 5 is opened, and the data cable 4 is inserted. After the data cable 4 is installed, the adjusting wheel 8 is rotated in the reverse direction, and the rubber pads on the clamping plate 10 and the guard plate 11 are in contact with the outer surface of the data cable 4, and the clamping plate 10 clamps the data cable 4.
