[0024] As attached Figure 1 To Attachment Figure 4 As shown:

[0025] The utility model provides an RFID explosion-proof label, including a label plate body 1, the label plate body 1 includes a placement slot 3, a protective cover 2 is arranged above the placement slot 3, clamping blocks 9 are installed on both sides of the protective cover 2, openings 15 are opened on both sides of the inner wall of the placement slot 3, and slots 4 are correspondingly opened on both sides of the inner walls of the two openings 15, a first spring 5 is installed on one side of the inner wall of multiple slots 4, one end of multiple first springs 5 ​​extends to the inside of the opening 15, a wedge block 6 is installed on one end of the multiple first springs 5, one ends of two wedge blocks 6 on the same side are abutted, and a clamping mechanism is arranged inside the two openings 15.

[0026] The locking mechanism includes a plurality of sliders 7, which are respectively installed under the corresponding wedge blocks 6. Slide grooves 8 are respectively provided on both sides of the lower inner wall of the opening 15 corresponding to the sliders 7, and the plurality of sliders 7 are respectively slidably installed on the inner walls of the corresponding slide grooves 8.

[0027] Among them, the locking mechanism also includes a groove 10, which is arranged below the inner wall of the opening 15, and a second spring 12 is installed below the inner wall of the groove 10, and a stop block 11 is installed on the top of the second spring 12. Through the joint cooperation of the protective cover 2, the placement slot 3, the slot 4, the first spring 5, the wedge block 6, the block 9, the slider 7, the slide slot 8, the stop block 11, the second spring 12, and the opening 15, the label body inside the placement slot 3 can be quickly replaced or torn off, and the block 9 can be fixed by clamping the block 9 in the groove 10 and the groove 10 cooperates with the wedge block 6, so as to quickly fix and install the protective cover 2, and the protective cover 2 has a certain protective effect, reducing the possibility of damage to the label, thereby facilitating the staff to quickly replace the label in the placement slot 3.

[0028] Among them, a fixing plate 13 is installed on one side above the multiple wedge blocks 6, and the multiple fixing plates 13 cover the opening 15. By installing the fixing plates 13 on both sides above the opening (15), the opening (15) can be sealed to prevent dust from entering the device. At the same time, the staff drives each fixing plate 13 to move in the opposite direction, which can drive the corresponding wedge block 6 to run. Combined with the action of the second spring 12 and the stop block 11, the restriction of the card block 9 can be released, and the staff can open the protective cover 2 to replace the label.

[0029] Among them, matching wedge surfaces are arranged between the two clamping blocks 9 and the two wedge blocks 6 on the corresponding side respectively. Through the setting of the wedge surfaces, when the clamping block 9 contacts with the wedge block 6, it can smoothly squeeze the wedge block 6 to move, so that the Shudie clamping block 9 can be stuck in the groove 10.

[0030] Among them, a notch is commonly provided on one side of the lower surface of the two wedge blocks 6 on the same side, and the sizes of the two notches are respectively adapted to the block 9 on the corresponding side. Through the cooperation between the notch and the groove 10, the block 9 can be smoothly placed inside this space.

[0031] Among them, L-shaped handles 14 are installed on both sides of the upper surface of the protective cover 2. The installation of the L-shaped handles 14 makes it convenient for staff to use. A transparent window is set above the label plate body 1. The setting of the transparent window makes it convenient for staff to scan the internal label and observe the internal label status at the same time.

[0032] The working principle of this embodiment is as follows: first, the staff puts the label inside the placement slot 3, and then the staff presses the L-shaped handle 14 with both hands to drive the protective cover 2 to move downward. At the same time, the card blocks 9 on both sides move under the drive of the protective cover 2. When the card blocks 9 on both sides contact the two wedge blocks 6 respectively, under the action of the wedge surface, the two wedge blocks 6 can be squeezed to move in opposite directions. The two wedge blocks 6 are driven to squeeze the corresponding first springs 5 ​​respectively, and the first springs 5 ​​are forced to shrink toward the inside of the slot 4. At this time, the card block 9 continues to descend until the card block 9 is in the groove 10, and the first spring 5 loses the pressure restriction and restores the rebound force, so that the two corresponding wedge blocks 6 are abutted again;

[0033] Secondly, when the card block 9 drops into the groove 10, its bottom will squeeze the stop block 11, and the stop block 11 will squeeze the second spring 12 with force until the card block 9 is completely in the groove 10; at this time, the card block 9 is fixed, and then the protective cover 2 is fixed. Under the action of the protective cover 2, the label can be protected, and the staff can also perform scanning work under the action of the transparent window;

[0034] Finally, when the label needs to be replaced, the staff can press the corresponding fixing plates 13 on both sides with both hands to drive the fixing plates 13 to move in opposite directions. The movement of the fixing plates 13 can drive the wedge block 6 to move. When the wedge block 6 is opened, the top of the card block 9 loses the pressure restriction. At this time, the second spring 12 at the bottom of the groove 10 is also pressure-restricted, thereby restoring the elastic force to apply force to the block 11. The block 11 is forced to eject the block 9, so that the restriction on the protective cover 2 can be released, so that the internal label can be replaced.

[0035] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
