Description

Technical Field

[0001] The utility model belongs to the technical field of embedded tags and relates to a novel installation structure of an RFID tag. Background Art

[0002] As a data carrier, the electronic tag based on RFID technology can play the roles of identification, item tracking, and information collection, and has a wide range of applications in many fields such as anti-counterfeiting, production line management, warehousing management, and logistics.

[0003] The existing installation technologies of RFID tags mainly involve their specific applications in different industries and application scenarios. For example, stickers with sticky glue on the back can be directly attached to the surface of objects such as packages, goods, and documents; tags embedded in products or components during the manufacturing process, and this method requires ensuring that the tags can still work properly inside the objects; tags for installation on metal or other solid surfaces are fixed to the object surface by screws or welding to ensure that the tags are not easily moved or damaged.

[0004] However, there are still many defects to be solved in the above existing installation methods. Firstly, in the case of the sticking method, the quality and adhesion of the sticky glue determine whether the tag can be firmly adhered to the object surface for a long time. Under humid, high-temperature, or extremely freezing conditions, the stickiness may weaken, resulting in the tag falling off or being damaged. Secondly, embedded tags require the use of specialized equipment and technologies, which will increase the complexity and cost of production or assembly, and there are special requirements for the part materials. Changes in materials may cause the performance of RFID to deteriorate. The embedded tag method also makes its own maintenance extremely difficult. Often, it can only damage or significantly intervene in the object itself, involving a large amount of time and cost. Thirdly, if the RFID tag is fixed to the object by screws, it may cause the risk of physical damage, especially on objects that have already been assembled or produced. It may be necessary to disassemble some components or perform other complex operations, which will increase the complexity and cost of maintenance.

[0005] Therefore, there is an urgent need for a more excellent installation method for users to choose. Content of the Utility Model

[0010] Furthermore, a flange is provided on the outer periphery of one end of the core pulling member, the outer diameter of the flange is larger than the inner diameter of the through hole, and the flange abuts against one end of the collapsed portion relative to the retaining ring.

It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0024] It should be noted that the diagrams provided in the following embodiments only schematically illustrate the basic concept of the present utility model. Therefore, only the components related to the present utility model are shown in the diagrams, rather than being drawn according to the number, shape, and size of the components in actual implementation. The type, quantity, and ratio of each component in actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0025] All directional indications (such as up, down, left, right, front, back, horizontal, vertical...) in the embodiments of the present utility model are only used to explain the relative position relationship and movement conditions between components in a certain specific posture. If this specific posture changes, then the directional indications will also change accordingly.

[0026] Due to reasons such as installation errors, the parallel relationship referred to in the embodiments of the present utility model may actually be an approximate parallel relationship, and the perpendicular relationship may actually be an approximate perpendicular relationship.

[0027] The utility model provides a novel installation structure for an RFID tag, which is used to fixedly install the RFID tag into a to-be-tested installation part.

[0028] Specifically, the installation area on the to-be-tested installation part should at least include an installation panel 1 with a certain thickness, and an installation hole 11 is penetratingly provided on the installation panel 1.

[0029] Refer to Figure 1 As shown, the RFID tag in this embodiment includes a temperature measurement probe 41 and a connecting wire 42. The temperature measurement probe 41 is arranged at one end of the connecting wire 42, and the transmission of data information is provided through the connecting wire 42. The installation structure includes a collapsible part and a core-pulling part 3. The core-pulling part 3 is in a columnar structure, and the middle part of the core-pulling part 3 is provided with a through hole along the axial direction, so that the connecting wire 42 can be axially inserted into the core-pulling part 3. A perforation 23 is penetratingly provided in the middle part of the collapsible part, so that the core-pulling part 3 can be inserted into the collapsible part through the perforation 23.

[0030] The connecting wire 42 and the core-pulling part 3 can form a certain tight fit in terms of size to maintain the stable positional relationship between the RFID tag and the core-pulling part 3.

[0031] Refer to Figure 3 As shown, the collapsible part includes a retaining ring 22 and a collapsible part 21, and the positions of the retaining ring 22 and the collapsible part 21 are distributed along the axial direction of the perforation 23, so that the collapsible part 21 is arranged to surround the outer periphery of the core-pulling part 3. The outer diameter of the core-pulling part 3 is slightly smaller than the inner diameter of the perforation 23, so that a clearance fit is formed between the outer periphery of the core-pulling part 3 and the inner periphery of the perforation 23, which is convenient for the axial movement of the core-pulling part 3 relative to the collapsible part 21.

[0032] A flange 31 is provided on the outer periphery of one end of the core-pulling part 3 in the axial direction. When the core-pulling part 3 is installed and matched with the collapsible part, the flange 31 is located on the side close to the collapsible part 21. When the core-pulling part 3 is pulled relative to the collapsible part, the flange 31 can abut against one axial end of the collapsible part 21.

[0033] The outer diameter of the collapsible part 21 is slightly smaller than the inner diameter of the installation hole 11, the outer diameter of the flange 31 is larger than the inner diameter of the perforation 23 and smaller than the inner diameter of the installation hole 11, and the outer diameter of the retaining ring 22 is larger than the inner diameter of the installation hole 11. Therefore, when setting, the flange 31 and the collapsible part 21 can pass through the installation hole 11 until the retaining ring 22 abuts against the installation panel 1.

[0034] When setting the RFID tag in the installation area of the installation part to be measured, first, the collapsible part, the core-pulling part 3, and the connecting wire 42 are sequentially passed through in place, and the temperature measurement probe 41 is located on the side close to the flange 31. Then, the temperature measurement probe 41, the core-pulling part 3, and the collapsible part 21 are inserted into the installation hole 11. After the temperature measurement probe 41 passes through the installation part to be measured, while keeping the retaining ring 22 in contact with the installation panel 1, the core-pulling part 3 is axially pulled outwards, so that the flange 31 generates an axial extrusion force on the collapsible part 21.

[0035] Referring to Figure 2 As shown, under the extrusion force reaching the set value, the collapsible part 21 undergoes deformations including but not limited to axial and radial directions. On the one hand, through the deformation, the outer diameter of some positions on the collapsible part 21 is enlarged, making its outer diameter larger than the inner diameter of the installation hole 11, so that together with the retaining ring 22, they respectively abut against both sides of the installation hole 11, realizing the fixation between the collapsible part and the installation part to be measured.

[0036] On the other hand, through the deformation, the inner diameter of some positions in the perforation 23 is reduced, making its inner diameter smaller than the outer diameter of the core-pulling part 3, so as to generate extrusion on the core-pulling part 3 to form an interference fit, realizing the fixation between the collapsible part and the core-pulling part 3.

[0037] Therefore, when the collapse action of the collapsible part 21 is completed, the RFID tag, the core-pulling part 3, and the collapsible part together form a stable fixation effect with the installation part to be measured.

[0038] The collapsible part is made of a material with certain plastic deformation ability and excellent elastic recovery ability, including but not limited to high-elastic alloys such as steel and aluminum alloy, or high-performance polymers such as polyamide and polycarbonate, so that the collapsible part 21 can effectively undergo a certain degree of deformation when subjected to the extrusion force. Moreover, multiple folded and bent parts are formed on the collapsible part 21 after the collapse deformation, and these parts generate better elasticity through their structures. Thus, during the installation process or subsequent use process, when the nearby area is subjected to accidental impact loads, these parts of the collapsible part 21 can effectively absorb and disperse the impact energy.

[0039] Furthermore, after the collapse of the collapsible part 21, the contact area with the installation panel 1 and the core-pulling part 3 is larger and the contact is more sufficient, thus effectively improving the heat conduction effect. The temperature change on the installation panel 1 can be well conducted through the collapsible part and the core-pulling part 3 to the temperature measurement probe 41.

[0040] In one embodiment, referring to Figure 3 , the collapsible part 21 has a cylindrical structure, the perforation 23 is arranged along the axis direction of the collapsible part 21, and the core-pulling part 3 is coaxially inserted into the collapsible part 21.

[0041] In another embodiment, referring to Figure 4 andFigure 5 , a branch rod 24 is further provided on the outer periphery of the collapsible part 21. The branch rod 24 is obliquely arranged on the plane formed by the axial direction and the radial direction of the collapsible part 21, so that a set angle is formed between the branch rod 24 and the axial direction of the collapsible part 21. When setting, the angle between the branch rod 24 and the collapsible part 21 can be deformed and become smaller so as to pass through the mounting hole 11. After passing through, the end of the branch rod 24 faces the mounting panel 1. The axial collapse of the collapsible part 21 causes the end of the branch rod 24 to abut against the mounting panel 1, and together with the collapsible part 21, a supporting effect of a triangular structure is formed. The angle formed between the branch rod 24 and the collapsible part 21 forms a certain deformation elasticity, thereby enhancing the impact resistance of the collapsible part 21; two branch rods 24 can be provided and are symmetrically arranged with the collapsible part 21 as the center, improving the installation stability and impact resistance.

[0042] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.
