Description

Technical Field

[0001] This utility model relates to the field of probe protection, and in particular to a moisture-proof and impact-proof protection device for electromagnetic field probes. Background Technology

[0002] The electromagnetic field probe is the core sensor component of an electromagnetic radiation analyzer. It typically consists of a high-precision antenna and electronic components, used to accurately measure the intensity and frequency of electromagnetic fields at specific spatial locations. In environmental electromagnetic radiation monitoring, base station acceptance testing, and other similar work, the electromagnetic field probe usually needs to be mounted on a dedicated non-metallic tripod and deployed and measured at a designated location for an extended period of time.

[0003] The main drawbacks of existing technologies during use are: the probe is easily damaged by moisture, affecting detection accuracy; electromagnetic field probes are precision electronic devices with limited sealing properties of their housings. When used outdoors, in rainy weather, in high humidity environments, or in environments with large temperature differences, moisture can easily penetrate the probe's interior, causing internal circuit boards to become damp, components to corrode, and insulation performance to deteriorate, thus severely affecting the accuracy and stability of measurement data, and even causing permanent damage to the probe. Therefore, those skilled in the art have provided a moisture-proof and impact-resistant protection device for electromagnetic field probes to solve the problems mentioned in the background art. Utility Model Content

This device solves the problems of existing probes being easily damaged by moisture, affecting detection accuracy, and when used outdoors, in rainy weather, in high humidity environments, or in environments with large temperature differences, moisture can easily penetrate the probe, causing internal circuit boards to become damp, components to corrode, and insulation performance to deteriorate, thereby seriously affecting the accuracy and stability of measurement data.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a moisture-proof and impact-proof protection device for an electromagnetic field probe, comprising a probe body and a protective shell. The protective shell is wrapped around the outer wall of the probe body. A semi-threaded pipe is connected to the bottom side of the protective shell, and an mounting component is fitted onto the semi-threaded pipe. Sealing gaskets are installed on the upper and lower sides of the mounting component. A connector is installed on the periphery of the protective shell, and a protective cover is installed at the end of the connector away from the protective shell. A through hole is provided on the outer wall of the protective cover. The through hole reduces the weight of the protective cover and effectively prevents moisture from accumulating inside the protective cover and penetrating into the protective shell, thus preventing damage to the electronic components inside the probe body.

[0006] Preferably, two semi-threaded pipe fittings are provided, and the two semi-threaded pipe fittings are symmetrically arranged. The depth of the mounting piece is greater than the depth of the semi-threaded pipe fitting. The mounting piece and the semi-threaded pipe fitting are threaded together. When the connector at the bottom of the probe body is connected to the upper cable end of the tripod equipped with the probe, the sealing gasket is squeezed and compressed to form a waterproof and dustproof sealing barrier.

[0007] Preferably, the protective shell is made of polycarbonate, which has low electromagnetic wave loss and high wave transmittance. This material can ensure that the signal can penetrate without attenuation and has excellent waterproof performance. The inner wall of the protective shell is in close contact with the outer shell of the probe body.

[0008] Preferably, the connector and the protective cover are made of silicone material.

[0009] Preferably, the connector is semi-cylindrical, and a positioning bolt and a positioning groove are provided on the inner side of the connector.

[0011] Through design, the protective shell outside the probe body can provide initial moisture protection. The semi-threaded tube at the bottom of the protective shell is spliced ​​and threaded to the mounting piece, and sealing gaskets are installed on both sides of the mounting piece. When connected to the tripod accessory, it can form a waterproof and dustproof sealing barrier. Protective covers are installed on the periphery of the protective shell through connectors, which can cushion and protect the internal probe from damage in the event of an impact. The openings on the outer wall of the protective cover reduce weight and prevent moisture accumulation and penetration, thus avoiding damage to the electronic components inside the probe body.

[0017] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides the following technical solution: a moisture-proof and impact-proof protection device for an electromagnetic field probe, comprising a probe body 5 and a protective shell 1. The protective shell 1 is wrapped around the outer wall of the probe body 5. A semi-threaded pipe fitting 101 is connected to the bottom side of the protective shell 1. An installation part 4 is sleeved on the semi-threaded pipe fitting 101. Sealing gaskets 401 are installed on the upper and lower sides of the installation part 4. A connector 2 is installed on the periphery of the protective shell 1. A protective cover 3 is installed at the end of the connector 2 away from the protective shell 1. A through hole 301 is opened on the outer wall of the protective cover 3. The through hole 301 reduces the weight of the protective cover 3 and effectively prevents moisture from accumulating inside the protective cover 3 and penetrating into the protective shell 1, which could damage the electronic components inside the probe body 5.

[0018] Furthermore, there are two semi-threaded pipe fittings 101, which are symmetrically arranged. The depth of the mounting part 4 is greater than the depth of the semi-threaded pipe fitting 101. The mounting part 4 is threadedly connected to the semi-threaded pipe fitting 101. When the connector at the bottom of the probe body 5 is connected to the upper cable end of the tripod equipped with the probe, the sealing gasket 401 is squeezed and compressed to form a waterproof and dustproof sealing barrier. The protective shell 1 is made of polycarbonate, which has low electromagnetic wave loss and high wave transmission. This material can ensure signal penetration without attenuation and has excellent waterproof performance. The inner wall of the protective shell 1 is in close contact with the outer shell of the probe body 5. The connector 2 and the protective cover 3 are made of silicone material. The connector 2 is semi-cylindrical. The inner side of the connector 2 is provided with a positioning bolt 201 and a positioning groove 202. Adjacent connectors 2 are aligned with each other. The positioning bolt 201 and the positioning groove 202 are inserted into each other for positioning, which can further increase the stability of the protective cover 3 when docking.

[0019] The working principle of this device is as follows: The probe body 5 is wrapped with a protective shell 1, which is split in half. The protective shell 1 is made of polycarbonate, which has low electromagnetic wave loss and high wave transmission. This material can ensure that the signal can pass through without attenuation and has excellent waterproof performance.

[0020] A semi-threaded pipe fitting 101 is installed at the bottom of the protective housing 1. When the protective housing 1 is spliced ​​and aligned, the two semi-threaded pipe fittings 101 form a complete threaded pipe. An installation part 4 is threaded onto the threaded pipe, and the depth of the installation part 4 is greater than that of the semi-threaded pipe fitting 101. Sealing gaskets 401 are provided on the upper and lower sides of the thread. When the connector at the bottom of the probe body 5 is connected to the upper cable end of the tripod equipped with the probe, the sealing gaskets 401 are squeezed and compressed to form a waterproof and dustproof sealing barrier.

[0021] A connector 2 is connected to the periphery of the protective shell 1. A protective cover 3 is installed on the outer end of the connector 2. Both the connector 2 and the protective cover 3 are made of silicone, which has good cushioning and resilience. It can buffer when the protective cover 3 is bumped, thereby protecting the protective shell 1 inside the protective cover 3 and the probe body 5 inside the protective shell 1, avoiding equipment damage caused by accidental collision. When the two protective covers 3 are aligned and spliced, the corresponding positioning bolts 201 and positioning grooves 202 are provided on the inner sides of the connector 2. The stability of the protective covers 3 when they are docked can be further increased by the insertion of the positioning grooves 202 and the positioning bolts 201.

[0022] Furthermore, several through holes 301 are opened on the outer wall of the protective cover 3. While reducing the weight of the protective cover 3, it can effectively prevent water vapor from accumulating inside the protective cover 3 and penetrating into the protective shell 1, which could damage the electronic components inside the probe body 5.
