Detailed Description

The drawings are for illustrative purposes only and are not to be construed as limiting the present patent; for the purpose of better illustrating the present embodiment, certain elements of the drawings may be omitted, enlarged or reduced and do not represent the actual product dimensions.

It will be appreciated by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted. The technical scheme of the utility model is further described below with reference to the accompanying drawings and examples.

The radio frequency sensing element mounting structure shown in fig. 1 comprises an abutting part 1, a connecting part 2 extending outwards from the abutting part 1, and a locking part 3 arranged on the connecting part 2, wherein a radio frequency sensing element 4 is arranged on the locking part 3, a metal part 5 connected with the connecting part 2 is sleeved outside the locking part 3, one end of the metal part 5, which is close to the abutting part 1, is an open end, the other end of the metal part 5 is a closed end, an electromagnetic wave channel 5a is arranged between the locking part 3 and a protecting part, one end of the electromagnetic wave channel 5a extends to the open end of the metal part 5, and the other end of the electromagnetic wave channel 5a is connected with the radio frequency sensing element 4; also comprises a gasket 6, wherein the gasket 6 comprises a wave-transmitting ring 62, and the metal piece 5 abuts against the abutting piece 1 through the wave-transmitting ring 62. In this embodiment, the connecting member 2 is a bolt, the locking member 3 is a nut screwed to the bolt, and the closed end of the metal member 5 is formed with a threaded hole screwed to the bolt. In view of various application occasions of the bolts, a designer mostly leaves a margin for the length of the bolts, so that the radio frequency sensing element mounting structure of the embodiment can be suitable for most of artifacts with the bolts, such as machinery, buildings and the like, and has high applicability.

Preferably, as shown in fig. 2, the outer side wall of the locking member 3 is provided with a receiving cavity 3a, and the radio frequency sensing element 4 is arranged in the receiving cavity 3a, so that the locking member 3 can maintain its original outer contour, thereby facilitating the installation of the locking member 3, and in addition, a gap is maintained between the radio frequency sensing element 4 and the inner wall of the receiving cavity 3a, thereby facilitating the prevention of the signal of the radio frequency sensing element 4 from being blocked by the inner wall of the receiving cavity 3 a.

Preferably, as shown in fig. 2, the accommodating cavity 3a is encapsulated with a mounting seat 7, the mounting seat 7 is made of non-metal materials, and the radio frequency sensing element 4 is arranged in the mounting seat 7. In practice, the installer firstly installs the rf sensing element 4 into the mounting seat 7, then encapsulates the mounting seat 7 in the accommodating cavity 3a through the epoxy resin glue, the mounting seat 7 always keeps a gap between the rf sensing element 4 and the inner wall of the accommodating cavity 3a, so that the installer does not need to finely adjust the position of the rf sensing element 4 in the process of installing the rf sensing element 4, thereby preventing the rf sensing element 4 from directly contacting the inner wall of the accommodating cavity 3a, and the signal of the rf sensing element 4 is blocked by the inner wall of the accommodating cavity 3 a.

Preferably, the radio frequency sensing element 4 is an RFID electronic temperature measuring element. Accordingly, the mounting seat 7 is made of a non-metal material with high heat conductivity coefficient, so that the mounting seat 7 can not obstruct the signal transmission of the radio frequency sensing element 4, and is beneficial to the heat transmission of the locking piece 3 to the RFID electronic temperature measuring element. In operation, the external device sends an excitation electrical signal (the signal includes energy and instructions) to the RFID electronic temperature measuring element, so that the RFID electronic temperature measuring element operates to acquire the temperature value of the locking member 3, and the acquired temperature value is fed back to the external device in the form of an electrical signal. It will be appreciated that in other embodiments, the RF sensor element 4 may also be an RFID electronic load cell, an RFID electronic seismic sensor, or the like.

As shown in fig. 3, the wave-transmitting ring 62 is made of epoxy resin, has a thickness of 1mm, and extends between the locking member 3 and the abutment member 1, so that the wave-transmitting ring 62 can disperse the pressure of the locking member 3 on the abutment member 1 to a certain extent, and the abutment member 1 is prevented from being scratched.

As a further optimization, the gasket 6 further comprises a metal ring 61, the axial lines of the metal ring 61 and the wave-transparent ring 62 are overlapped, and the locking piece 3 abuts against the abutting piece 1 through the metal ring 61. As an example, as shown in fig. 4 and 5, the metal ring 61 and the wave-transmitting ring 62 are integrally connected. It can be understood that, compared with the wave-transparent ring 62, the metal ring 61 can bear larger pressure, and the metal ring 61 is used for replacing the part of the wave-transparent ring 62 extending between the locking member 3 and the abutting member 1, so that the locking member 3 can adopt larger mounting force, which is beneficial to improving the connection stability of the locking member 3.

As an example, as shown in fig. 4, the end of the metal ring 61 is flat, so as to facilitate dispersion of the pressure of the locking member 3 against the abutment member 1.

Of course, to further avoid loosening of the locking member 3, in another embodiment, the metal ring 61 is further provided with a plurality of elastic portions 611 uniformly distributed along the circumferential direction, as shown in fig. 5.

Preferably, as shown in fig. 4 and 5, the wave-transmitting ring 62 includes a hard layer 621 and an elastic layer 622 wrapped around the hard layer 621. The hard layer 621 can prevent the metal piece 5 from being too close to the abutment 1 due to too large installation force of the metal piece 5 in the installation process, so that a gap between the metal piece 5 and the abutment 1 is too small, and signal transmission of the radio frequency sensing element 4 is affected. In addition, in order to improve the tightness between the metal piece 5 and the abutting piece 1, the elastic layer 622 is wrapped on the outer side of the hard layer 621, wherein the elastic layer 622 can more effectively block the gap between the metal piece 5 and the abutting piece 1, and prevent external impurities from entering the metal piece 5. In this embodiment, the hard layer 621 is made of epoxy resin glue, and has a thickness of 1mm; the elastic layer 622 is made of rubber and has a thickness of 0.5mm.

A cable head comprising the above-described rf sensor element mounting structure is shown in fig. 6.
