Description

An anti-drop RFID asset management tag device Technical Field

[0001] The present invention relates to the technical field of RFID electronic tags, and in particular to an anti-dropout RFID asset management tag device. Background Art

[0002] RFID tags are a type of wireless radio frequency identification technology that transmits signals via radio waves, enabling fast, long-distance, and contactless automatic identification and data exchange. RFID tag systems consist of three components: tags, readers, and antennas. They are widely used in logistics, supply chain, manufacturing, retail, healthcare, transportation, and personal identification.

[0003] Chinese patent application number CN202322397256.8 discloses an anti-slip RFID asset management tag device, comprising a tag body, a back plate provided on one side of the tag body, and an anti-slip structure provided on one side of the back plate; the anti-slip structure includes a base plate, and two first clamping plates are symmetrically arranged on the side walls of the base plate in the transverse direction, and a second clamping plate is symmetrically arranged on the side walls of the base plate. A third clamping plate is integrally formed on the end of the second clamping plate away from the base plate; by providing the anti-slip structure, the first clamping plate included in the anti-slip structure clamps the side wall of the object connection, while the second and third clamping plates clamp the front and rear side walls of the object connection to prevent the tag device from sliding up and down along the object connection. Several groups of clamping plates cooperate with each other to fix the tag body to the object, effectively preventing the tag device from falling off. The advantage of this structure is that it is not affected by the environment and has a long service life. The device fixes the electronic tag by providing multiple clamping plates to cooperate with each other to clamp on the object, but some objects do not have the conditions for clamping, which limits the use of the device and has a small scope of application.

[0004] In view of this, the present invention proposes an anti-dropping RFID asset management tag device to solve the problems existing in the above-mentioned prior art. Summary of the Invention

[0023] Example 1: Please refer to Figures 1 to 3, an anti-dropping RFID asset management tag device includes a fixed disk 2 and a tag body 3, the bottom outer wall of the fixed disk 2 is fixedly connected to two fixed columns 15, and the bottom ends of the two fixed columns 15 are fixedly connected to the same pressing disk 9, and the bottom end of the pressing disk 9 is provided with an adhesive layer 8, the outer walls of the two fixed columns 15 are sealingly and slidingly connected to the same isolation cover 1, and the bottom outer wall of the isolation cover 1 is provided with a receiving groove 16, the inner wall of the receiving groove 16 is slidably connected to a lifting disk 11, and a plurality of connecting springs 12 are fixedly connected between the lifting disk 11 and the receiving groove 16, the bottom outer wall of the lifting disk 11 is fixedly connected to an isolation airbag 10, and the lower part of the isolation airbag 10 extends out of the receiving groove 16, pressing mechanisms are provided on both sides of the top of the isolation cover 1, and a plurality of connecting springs are fixedly connected between the top outer wall of the isolation cover 1 and the bottom outer wall of the fixed disk 2 2. 14. By setting the adhesive layer 8, the label body 3 can be fixed anywhere without being restricted, and when the adhesive layer 8 is adhered, the isolation cover 1 on the two fixed columns 15 is moved downward by the pressing mechanism, so that the isolation airbag 10 in the receiving groove 16 at the bottom end of the isolation cover 1 can contact the surface of the adhered place. As the isolation cover 1 continues to move downward, the isolation airbag 10 is squeezed, so that more and more of the isolation airbag 10 enters the receiving groove 16, which will cause the lifting plate 11 to press the multiple connecting springs 12 to move upward in the receiving groove 16, so that under the action of the rebound force of the multiple connecting springs 12, the isolation airbag 10 forms a sealing structure with the surface of the adhered place, so that external moisture, dust and other impurities will not enter the isolation cover 1, so that the adhesive layer 8 will not be affected by the external environment, thereby avoiding failure of the adhesive layer 8.

[0024] Among them, the pressing mechanism includes a threaded rod 7, which is threadedly slidably connected to the outer wall of one side of the top of the fixed plate 2, and the top of the threaded rod 7 is fixedly connected to a knob 6, and the bottom end of the threaded rod 7 is fixedly connected to a limiting elliptical head 13, and the limiting elliptical head 13 is in contact with the top outer wall of the isolation cover 1. The threaded rod 7 is rotated by the knob 6, so that the threaded rod 7 moves downward, and the isolation cover 1 can be pressed by the limiting elliptical head 13, so that the isolation cover 1 moves downward along the fixed column 15.

[0025] A placement slot 5 is provided on the top of the fixing plate 2 , and the label body 3 is placed in the placement slot 5 .

[0026] An accommodating cavity 18 is provided below the placement slot 5 , and both sides of the accommodating cavity 18 are slidably connected with L-shaped clamping plates 4 .

[0027] The tag body 3 is located between the two L-shaped clamping plates 4 , and the two L-shaped clamping plates 4 are fixedly connected to the opposite sides thereof with a slide plate 19 .

[0028] Among them, the two slides 19 are both slidably connected to the inner wall of the accommodating cavity 18, and a connecting spring three 17 is fixedly connected between the two slides 19. Through the elastic force of the connecting spring three 17, the two L-shaped clamping plates 4 are brought close to each other. Since the label body 3 is located between the two L-shaped clamping plates 4, the two L-shaped clamping plates 4 can clamp and fix the label body 3, so that the label body 3 is fixed in the placement groove 5 of the fixed plate 1.

[0029] Working principle: By setting the adhesive layer 8, the label body 3 can be fixed anywhere without being restricted, and when the adhesive layer 8 is adhered, the threaded rod 7 is rotated by the knob 6, so that the threaded rod 7 moves downward, and the isolation cover 1 can be pressed by the limiting elliptical head 13, so that the isolation cover 1 moves downward along the fixed column 15, so that the isolation air bag 10 in the receiving groove 16 at the bottom end of the isolation cover 1 can contact the surface of the adhered place, and as the isolation cover 1 continues to move downward, the isolation air bag 10 is squeezed, so that more and more of the isolation air bag 10 enters the receiving groove 16, which will cause the lifting plate 11 to press the multiple connecting springs 12 to move upward in the receiving groove 16, so that under the action of the rebound force of the multiple connecting springs 12, the isolation air bag 10 forms a sealing structure with the surface of the adhered place, so that external moisture, dust and other impurities will not enter the isolation cover 1, so that the adhesive layer 8 will not be affected by the external environment, thereby avoiding failure of the adhesive layer 8.

[0030] Example 2: Please refer to Figure 4, an anti-falling RFID asset management tag device. Compared with Example 1, the upper outer wall of one side of the two L-shaped clamping plates 4 is provided with a limiting plate 20 and a fixing bolt 21, and the limiting plate 20 is fixedly connected to the outer wall on the top side of the L-shaped clamping plate 4 by the fixing bolt 21, further limiting and fixing the tag body 3 to prevent accidental falling off.

[0031] Working principle: The limiting plate 20 is fixed to the outer wall of the L-shaped clamping plate 4 by the fixing bolts 21, so that the tag body 3 can be fixed in the vertical direction, thereby preventing the tag body 3 from escaping from the placement groove 5.
