Description

Technical Field

[0001] The utility model relates to the technical field of readers and writers, in particular to a long-range RFID ultra-high frequency reader and writer. Background Art

[0002] RFID reader, also known as RFID reader, is a wireless radio frequency identification. It automatically identifies the target object and obtains relevant data through radio frequency identification signals without human intervention. It can identify high-speed moving objects and can identify multiple RFID tags at the same time. It is quick and convenient to operate.

[0003] However, the shells of most existing UHF RFID readers are connected by bolts. When the UHF RFID reader shell needs to be disassembled for internal maintenance after a long period of operation, it takes a lot of time to use external tools to remove the bolts before the maintenance work can be carried out. At the same time, the bolts will rust over time and are inconvenient to remove, which will cause inconvenience to users during actual use. Utility Model Content

[0010] Preferably, one side of the output shaft of the two dual-axis motors and the middle part of the two long rods are respectively equipped with a first synchronous pulley and a second synchronous pulley, the outer rings of the first synchronous pulley and the second synchronous pulley are equipped with belts, and the two fan blades are not in contact with the two belts, and are separated by a distance with the same thickness as the lateral end of the U-shaped seat.

[0011] Preferably, the bottoms of the support legs are fixedly connected with friction pads.

[0012] The beneficial effects of the utility model are as follows:

[0013] 1. In the utility model, by pressing the four tightening blocks in the opposite direction to the connecting column, the pressing will squeeze every two corresponding springs. During the squeezing, the springs are in a compressed state so that the tightening blocks and the connecting column are released from the fixation. Then, the L-shaped rods are rotated in the middle of the four round rods in the opposite direction to the adjacent connecting columns through the corresponding bearings. After the rotation, the two shells are moved upward to pull the two groups of card blocks out of the corresponding card slots and separate them from the reader body.

[0014] 2. In the present invention, the heat generated by the reader body during operation is quickly absorbed by the heat conducting plate provided with copper material, and the heat absorbed by the heat conducting plate is quickly discharged through the provision of multiple heat dissipation fins to cool the top of the reader body. At the same time, the two output shafts of the dual-axis motor drive the two first synchronous pulleys to rotate. When the two first synchronous pulleys rotate, the two second synchronous pulleys are driven by the belt to rotate. The rotation of the two second synchronous pulleys drives the corresponding two long rods to rotate through the bearings, and then the fan blades rotate together to generate wind force, so that the user can conveniently perform heat dissipation and cooling on both sides and the top of the reader body to prevent damage to the internal electronic components caused by excessive temperature.

Support legs 8 are fixedly connected to the four sides of the bottom of the reader body 1, and a heat dissipation mechanism is provided at the bottom of the reader body 1.

[0024] Furthermore, a plurality of heat dissipating fins 3 are fixedly connected to the top of the heat conducting plate 2. The heat conducting plate 2 is made of copper. The heat conducting plate 2 made of copper can quickly absorb the heat generated during the operation of the reader body 1, and the setting of the plurality of heat dissipating fins 3 can quickly discharge the heat absorbed by the heat conducting plate 2 to cool the top of the reader body 1.

[0025] Furthermore, the positioning mechanism includes four round rods 10 fixedly connected to the left and right sides of the reader body 1, and the middle parts of the four round rods 10 are rotatably installed with L-shaped rods 11 through bearings. The inner walls of the L-shaped rods 11 are fixedly connected with springs 12 at equal distances, and one side of each two springs 12 is fixedly connected with a tightening block 13. Through the provided positioning mechanism, it is convenient for users to fix the shell 6 and the reader body 1 for use and disassemble it for internal maintenance.

[0026] Furthermore, a stopper 21 is fixedly connected to one side of the round rod 10 and the connecting column 7. The stopper 21 can prevent the user from offsetting and failing to fix the housing 6 when using the positioning mechanism to fix the housing 6.

[0027] Furthermore, the heat dissipation mechanism includes a U-shaped seat 14 fixedly connected to the bottom of the reader body 1, a dual-axis motor 15 is provided in the middle of the top of the U-shaped seat 14, and long rods 16 are rotatably installed on the left and right sides of the U-shaped seat 14 through bearings. One side of the two long rods 16 is fixedly connected to a fan blade 20, and one side of the output shaft of the two dual-axis motors 15 and the middle of the two long rods 16 are respectively provided with a first synchronous pulley 17 and a second synchronous pulley 18, and the outer rings of the first synchronous pulley 17 and the second synchronous pulley 18 are provided with a belt 19. The two fan blades 20 are not in contact with the two belts 19, and are separated by a distance with the same thickness as the lateral end of the U-shaped seat 14. Through the provided heat dissipation mechanism, it is convenient for users to dissipate heat and cool down both sides of the reader body 1 to prevent the temperature from being too high and unable to operate normally.

[0028] Furthermore, the bottom of the support legs 8 are fixedly connected with friction pads 9. By setting the friction pads 9, the friction resistance between the support legs 8 and the working ground when supporting the reader body 1 can be increased, which can improve the stability of the reader body 1 during use.

At the same time, the two output shafts of the dual-axis motor 15 drive the two first synchronous pulleys 17 to rotate. When the two first synchronous pulleys 17 rotate, the two second synchronous pulleys 18 are driven to rotate by the belt 19. The rotation of the two second synchronous pulleys 18 drives the corresponding two long rods 16 to rotate through the bearings, and then the fan blades 20 rotate together to generate wind force, so that the user can conveniently perform heat dissipation and cooling on both sides and the top of the reader / writer body 1 to prevent overheating. The phenomenon of excessive tension causing damage to the internal electronic components is that when the two shells 6 need to be disassembled and separated from the reader body 1 to open it, the four tightening blocks 13 are pressed in the opposite direction of the connecting column 7. When pressed, each two corresponding springs 12 are squeezed. When squeezed, the springs 12 are in a compressed state so that the tightening blocks 13 and the connecting column 7 are released from the fixation. Then, the L-shaped rods 11 are rotated in the opposite direction of the adjacent connecting columns 7 in the middle of the four round rods 10 through the corresponding bearings. After rotation, the two shells 6 are moved upward to pull the two groups of card blocks 5 out of the corresponding card slots 4 to separate them from the reader body 1, so that the user can easily separate the reader body 1 from the shell 6 to perform internal repair and maintenance, thereby preventing the inconvenience caused by wasting a lot of time removing bolts during maintenance.
