DETAILED DESCRIPTION

[0024] Referring to Figures 1-7 The protective device for easy replacement of the wireless radio frequency identification tag, including the protective shell 1 and the wireless radio frequency identification tag 2 arranged in the protective shell 1, the cavity 3 is arranged in the protective shell 1, the opening is arranged in the top end of the protective shell 1 and communicated with the cavity 3, the wireless radio frequency identification tag 2 is arranged in the cavity 3 through the opening, and at least one set of clamping device for fixing the wireless radio frequency identification tag 2 is arranged on the left and right sides of the protective shell 1.

[0025] The clamping device includes the clamping plate 4, the spring hinge 5, the motor 6 and the cam 7, the through slot 8 is arranged on the both sides of the protective shell 1, the clamping plate 4 is arranged in the through slot 8, the spring hinge 5 is arranged on the both sides of the clamping plate 4 arranged in the through slot 8, the fixed slot 9 for installing the spring hinge 5 is arranged in the through slot 8, the mounting groove 10 is arranged on the both sides of the bottom of the cavity 3 in the protective shell 1, the motor 6 is fixedly arranged in the mounting groove 10, the rotating rod 11 is arranged on the output end of the motor 6, and the cam 7 is fixedly arranged on the rotating rod 11. The clamping plate 4 is a thin and long pressing plate.

[0026] Further, the motor 6 is a servo motor, the rotating center of the rotating rod 11 is arranged below the clamping plate 4, and the top end of the rotating rod 11 exceeds the upper edge of the uppermost clamping plate 4.

[0027] Further, the cam 7 is arranged at the position below the clamping plate 4 of the rotating rod 11. When the base circle of the cam 7 is below the clamping plate 4, the cam 7 does not contact the clamping plate 4 at this time, and the clamping plate 4 is pressed to the wireless radio frequency identification tag 2 in the cavity 3 by the driving of the spring hinge 5, and when the rotating rod 11 rotates a circle, the raised part of the cam 7 contacts the bottom end of the clamping plate 4, and at this time, the cam 7 forces the clamping plate 4 to overcome the spring hinge 5 and make the clamping plate 4 lift up.

[0028] Further, the front of the protective shell 1 is provided with the observation window 12, and the transparent protective film is arranged in the observation window 12. The effective scanning area of the wireless radio frequency identification tag 2 is arranged in the observation window 12, and the core area can be protected through the protective film.

[0029] Further, the bottom of the front of the protective shell 1 is provided with a button 13, which is below the observation window 12. Since the motor 6 is a small power servo motor, the button 13 can be directly connected to the power supply line of the motor 6, and the switch of the motor 6 is controlled.

[0030] Further, the top and bottom of the protective shell 1 are provided with threaded holes 14. The protective shell 1 can be fixed at the desired position by screws.

[0031] Further, the height of the wireless radio frequency identification tag 2 is greater than the distance from the top of the protective shell 1 to the bottom of the cavity 3. In this way, the top of the wireless radio frequency identification tag 2 will always have a part outside the protective shell 1, which is convenient for the subsequent staff to pull out the wireless radio frequency identification tag 2. Since the effective scanning area of the wireless radio frequency identification tag 2 is arranged near the observation window 12, the upper end of the wireless radio frequency identification tag 2 can be exposed outside the protective shell 1.

[0032] In the embodiment of the utility model, please refer to Figures 1-7 , working principle: when the staff needs to insert the wireless radio frequency identification tag 2 into the protective shell 1, the servo motor is started through the button 13 at the bottom of the front of the protective shell 1, the cam 7 fixedly arranged on the output end of the motor 6 is arranged on the rotating rod 11, when the base circle of the cam 7 is below the clamping plate 4, the cam 7 will not contact the clamping plate 4 at this time, the clamping plate 4 at one end in the protective shell 1 will be pressed tightly downward by the driving of the spring hinge 5, after starting the motor 6, when the rotating rod 11 rotates a circle, the lifting part of the cam 7 will contact the bottom end of the clamping plate 4, at this time, the cam 7 will force the clamping plate 4 to overcome the driving force of the spring hinge 5 and make the clamping plate 4 lift, at this time, the wireless radio frequency identification tag 2 can be inserted into the protective shell 1, at this time, the motor 6 is closed again, the base circle of the cam 7 will be aligned below the clamping plate 4 again, at this time, the clamping plate 4 loses the lifting effect of the cam 7 and will be clamped tightly by the wireless radio frequency identification tag 2 under the driving of the spring hinge 5. When the wireless radio frequency identification tag 2 needs to be taken out, the motor 6 is started again, so that the lifting part of the cam 7 contacts the bottom end of the clamping plate 4 again and lifts the clamping plate 4, at this time, the staff can take out the wireless radio frequency identification tag 2 by pulling the upper end of the wireless radio frequency identification tag 2 exposed outside the protective shell 1.
