[0029] Refer to Figure 1As shown in the figure, the present utility model provides a technical solution: an RFID reader structure, which includes a reader body 1. A grip 2 is installed on the lower surface of the reader body 1. A protection device 3 is provided on one side of the reader body 1. By setting the protection device 3, the effect of protecting the surface screen of the reader body 1 is achieved. It avoids that after long-term use, the surface screen of the reader body 1 is covered with dust, or when the reader body 1 is idle, the screen of the reader body 1 is collided by sharp objects, resulting in the screen of the reader body 1 being unclear or damaged and unable to be used, thus causing the situation of reducing the work efficiency of the staff or reducing the service life of the reader body 1, and improving the practicability of the device. The arc surface of the grip 2 is provided with a support device 4. By setting the support device 4, the effect of supporting and placing the idle reader body 1 is achieved. It avoids that after the reader body 1 stops being used, there is no suitable placement position, resulting in the staff having to place the reader body 1 randomly, causing the control buttons or components on the reader body 1 to be rubbed or collided, thus causing the situation of damage to the components of the reader body 1, and improving the service life of the device.

[0030] The following specifically describes the specific settings and functions of its protection device 3 and support device 4.

[0031] Refer to Figure 2 、 Figure 3 and Figure 4As shown in the figure, in this embodiment: The protection device 3 includes a fixing plate 301, the fixing plate 301 is fixedly connected to one side of the reader-writer body 1, strip plates 302 are fixedly connected to both sides of the fixing plate 301, a rotating rod 303 is fixedly connected to the side of the two strip plates 302 close to each other, a connecting block 304 is rotatably connected to the arc surface of the rotating rod 303, a protective shell 305 is fixedly connected to one side of the connecting block 304, a fixing rod 306 is fixedly connected to the side of the reader-writer body 1 away from the fixing plate 301, an operating plate 307 is slidably connected to the arc surface of the fixing rod 306, a plug rod 308 is fixedly connected to the side of the operating plate 307 close to the reader-writer body 1, a semi-circular plate 309 is fixedly connected to the surface of the protective shell 305, a jack is opened on one side of the semi-circular plate 309, a limiting plate 310 is fixedly connected to the end of the fixing rod 306 away from the reader-writer body 1, the size of the plug rod 308 is adapted to the size of the jack of the semi-circular plate 309. When the staff pulls the operating plate 307, the operating plate 307 slides on the arc surface of the fixing rod 306. At this time, the limiting plate 310 achieves the effect of limiting the maximum distance of the operating plate 307 sliding on the arc surface of the fixing rod 306, avoiding the situation that when the staff pulls the operating plate 307, due to excessive pulling force, the operating plate 307 detaches from the arc surface of the fixing rod 306. A first spring 311 is sleeved on the arc surface of the fixing rod 306, and both ends of the first spring 311 are fixedly connected to the operating plate 307 and the reader-writer body 1 respectively. When the staff releases the operating plate 307, the resilience of the first spring 311 drives the operating plate 307 to slide on the arc surface of the fixing rod 306. At the same time, the operating plate 307 drives the plug rod 308 to move until the plug rod 308 is inserted into the jack of the semi-circular plate 309. At this time, the first spring 311 improves the stability of the plug rod 308 when limiting the semi-circular plate 309, and at the same time improves the stability of the plug rod 308 when limiting the protective shell 305, avoiding the situation that when the reader-writer body 1 is collided by an external force, the operating plate 307 unconsciously slides on the arc surface of the fixing rod 306, resulting in the operating plate 307 unconsciously taking the plug rod 308 away from the jack of the semi-circular plate 309. Two torsion springs 312 are sleeved on the arc surface of the rotating rod 303, and both ends of the torsion springs 312 are fixedly connected to the strip plate 302 and the connecting block 304 respectively. When the staff releases the limit of the plug rod 308 on the semi-circular plate 309, the torsion of the torsion spring 312 drives the connecting block 304 to rotate on the arc surface of the rotating rod 303. At the same time, the connecting block 304 drives the protective shell 305 to move until the protective shell 305 is taken away from the surface screen of the reader-writer body 1. At this time, the torsion spring 312 achieves the effect of automatically opening the protective shell 305, so as to reduce the operation steps of the staff on the device and improve the work efficiency of the staff.

[0032] Referring to Figure 5As shown in the figure, specifically, the support device 4 includes two support rings 41. Both of the two support rings 41 are slidably connected to the arc surface of the grip 2. One side of each of the two support rings 41 is fixedly connected to a support frame 42. The lower surface of the support frame 42 is fixedly connected to a base 43. Both sides of the support frame 42 are fixedly connected to L-shaped plates 44. A driving rod 45 is inserted into the L-shaped plates 44 in a threaded manner. One end of the driving rod 45 is rotatably connected to an adapter plate 46. The adapter plate 46 abuts against the arc surface of the grip 2. When the staff places the grip 2 into the hollow position between the two support rings 41 and then rotates the driving rod 45, the driving rod 45 moves in a threaded manner within the L-shaped plates 44. At the same time, the driving rod 45 drives the adapter plate 46 to move until the adapter plate 46 abuts against the arc surface of the grip 2. At this time, the effect of fixing and limiting the grip 2 is achieved, thereby achieving the effect of fixing and limiting the reader-writer body 1. This avoids the situation where after the support frame 42 is knocked down, the reader-writer body 1 follows the support frame 42 to fall to the ground, and the inertia generated during the fall causes the reader-writer body 1 to slide out of the support ring 41, resulting in the reader-writer body 1 falling from the desktop to the ground and being damaged. One side of the adapter plate 46 close to the driving rod 45 is fixedly connected to a positioning rod 47. The arc surface of the positioning rod 47 is slidably connected to the L-shaped plates 44. When the staff rotates the driving rod 45, the driving rod 45 moves in a threaded manner within the L-shaped plates 44. At the same time, the driving rod 45 drives the adapter plate 46 to move, and the adapter plate 46 drives the positioning rod 47 to slide within the L-shaped plates 44. At this time, the positioning rod 47 achieves the effect of restricting the adapter plate 46 from rotating along with the driving rod 45, so as to increase the stability when the adapter plate 46 abuts against the grip 2.

[0033] Working principle: When the staff needs to protect the screen on the surface of the reader-writer body 1, pull the operation plate 307 so that the operation plate 307 slides on the arc surface of the fixed rod 306, and the first spring 311 is stretched. At the same time, the operation plate 307 drives the insertion rod 308 to move until the insertion rod 308 no longer blocks the movement of the protective shell 305. At this time, press the protective shell 305, and the protective shell 305 drives the connecting block 304 to move on the arc surface of the rotating rod 303 until the protective shell 305 covers and blocks the screen on the surface of the reader-writer body 1. At this time, release the operation plate 307, and the resilience of the first spring 311 drives the operation plate 307 to slide on the arc surface of the fixed rod 306. At the same time, the operation plate 307 drives the insertion rod 308 to move until the insertion rod 308 is inserted into the jack of the semi-circular plate 309. At this time, the effect of protecting the screen on the surface of the reader-writer body 1 is achieved, avoiding the situation where after long-term use, the screen on the surface of the reader-writer body 1 is covered with dust, or when the reader-writer body 1 is idle, the screen of the reader-writer body 1 is collided by sharp objects, resulting in the screen of the reader-writer body 1 being unclear or damaged and unable to be used, thus reducing the work efficiency of the staff or the service life of the reader-writer body 1, and improving the practicability of the device.

[0034] When the staff needs to support and fix the reader-writer body 1, put the grip 2 into the support ring 41. At this time, rotate the driving rod 45 to make the driving rod 45 move in a threaded manner within the L-shaped plate 44. At the same time, the driving rod 45 drives the connecting plate 46 to move, and the connecting plate 46 drives the positioning rod 47 to slide within the L-shaped plate 44 until the connecting plate 46 abuts against the arc surface of the grip 2. At this time, the effect of supporting and placing the idle reader-writer body 1 is achieved, avoiding the situation that after the reader-writer body 1 stops being used, there is no suitable placement position, resulting in the staff having to place the reader-writer body 1 randomly, causing the control buttons or components on the reader-writer body 1 to be rubbed or collided, thus damaging the components of the reader-writer body 1, and improving the service life of the device.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood through specific situations.
