Description

Technical Field

[0001] This utility model relates to the field of radio monitoring technology, and more specifically to a wireless signal monitoring device. Background Technology

[0002] In the standardized examination room construction service, wireless signal monitoring devices are one of the core devices to ensure examination room order and prevent wireless communication cheating. Their core function is to monitor, analyze, identify and warn of wireless signals in and around the examination room in real time, thereby eliminating cheating behavior using mobile phones, walkie-talkies, wireless earphones and other devices. Some portable devices (such as small signal monitoring base stations and directional antenna devices) are used with tripods. These devices are usually placed around the examination room (such as in corridors, near the entrance of the examination site) or in corners inside the examination room. However, in actual use, due to the dense flow of people inside and outside the examination room (especially in areas that students must pass through, such as corridors and entrances), students may lose focus due to rushing or pre-exam anxiety, which may cause them to bump into the tripod. In order to achieve stability, the tripod legs are usually designed to be thin. Once it is hit, it is easy to tilt or even fall over, which may cause the equipment to fall and be damaged. In particular, the delicate signal receiving module, display screen and other components inside the equipment are very vulnerable to damage. Utility Model Content

Detailed Implementation

[0014] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0015] Figures 1-5 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-5 The present invention will be further described below.

[0016] A wireless signal monitoring device includes a tripod 1, a support plate 2 mounted on top of the tripod 1, and a radio signal monitoring device body 21 mounted on top of the support plate 2. A fixed cylinder 3 is fixedly connected at equal intervals inside the support plate 2. A sliding rod 4 is slidably connected inside the fixed cylinder 3. A connecting rod 5 is slidably connected inside the sliding rod 4. A second sliding rod 6 is longitudinally slidably connected inside the connecting rod 5. Sealing blocks 7 are fixedly connected to the end faces of the second sliding rod 6, the connecting rod 5, and the sliding rod 4. An adjustment component 8 is installed inside the support plate 2. The output end of the adjustment component 8 communicates with the interior of the fixed cylinder 3, and the input end of the adjustment component 8 extends to the top of the support plate 2.

[0017] In this embodiment, the retractable sliding rod 4, connecting rod 5, and sliding rod 6 are automatically extended through the adjusting component 8 to form an outer enclosure around the tripod 1. The end of sliding rod 6 touches the ground, greatly increasing the number and distribution range of support points. Compared with the traditional tripod 1 which is supported by only three thin legs, this structure can disperse the impact force, significantly reduce the risk of tilting or tipping of the equipment due to collision, effectively protect the precision components inside the main body 21 of the radio signal monitoring equipment, and improve the safety of use.

[0018] Specifically, the adjusting component 8 includes a sealing cavity 81 opened inside the support plate 2. A sealing disc 82 is longitudinally and slidably connected inside the sealing cavity 81. A rotating plate 85 is rotatably connected inside the sealing disc 82. An internally threaded tube 83 is fixedly connected to the top of the rotating plate 85. Insertion holes 84 are equidistantly opened on the surface of the internally threaded tube 83. The inner wall of the internally threaded tube 83 is threadedly connected to the inside of the support plate 2. A vent pipe 86 is fixedly connected inside the support plate 2. The bottom end of the sealing cavity 81 is connected to the inside of the fixed cylinder 3 through the vent pipe 86.

[0019] In this embodiment, the adjusting component 8 drives the sealing disc 82 to slide by rotating the internal threaded tube 83. The air pressure change between the sealing cavity 81 and the fixed cylinder 3 is used to control the extension and retraction of the sliding rod series. There is no need to manually stretch each section, which is convenient to operate and has high adjustment accuracy. The vent pipe 86 ensures that the air pressure is evenly transmitted to multiple fixed cylinders 3, so that each sliding rod can be deployed synchronously and the support balance is guaranteed. The threaded connection between the internal threaded tube 83 and the support plate 2 can lock the position of the sealing disc 82, maintain stable air pressure, and prevent the sliding rod from retracting unexpectedly.

[0020] Specifically, there are three sealing blocks 7. A sealing ring is fixedly installed on the outer surface of the sealing block 7. The sealing block 7 is hexagonal. The interior of the fixed cylinder 3, the sliding rod 4 and the connecting rod 5 are all provided with hexagonal grooves that match the sealing block 7.

[0021] In this embodiment, the sealing block 7 adopts a hexagonal design, which precisely matches the hexagonal grooves inside the fixed cylinder 3, sliding rod 4, and connecting rod 5. This effectively prevents relative rotation of the components and ensures stability in the direction of extension and retraction. The sealing ring on the outer surface of the sealing block 7 enhances the airtightness of the sliding connection, avoids air pressure leakage, ensures the reliability of air pressure drive, and reduces component wear, thus extending service life.

[0022] Specifically, sliding rod 4 is slidably connected to the inside of fixed cylinder 3 through sealing block 7, connecting rod 5 is slidably connected to the inside of sliding rod 4 through sealing block 7, and sliding rod 6 is slidably connected to the inside of connecting rod 5 through sealing block 7. The inside of sliding rod 6 is solid, connecting rod 5 is "L" shaped, and the insides of connecting rod 5 and sliding rod 4 are hollow. A ventilation groove is provided at the center of the surface of sealing block 7.

[0023] In this implementation scheme, the sliding rod 4 and the connecting rod 5 are hollow, which reduces the overall weight and provides space for air pressure transmission and the expansion and contraction of internal components. The sliding rod 6 is solid, which provides higher support strength when the end touches the ground, and also avoids air pressure leakage inside the connecting rod 5. The connecting rod 5 is L-shaped, which can extend outward after unfolding and make the sliding rod 6 slide downward, so that the sliding rod 6 touches the ground vertically, expanding the support radius. The ventilation groove on the surface of the sealing block 7 ensures that air pressure can be transmitted to each level of components in sequence, realizing linkage expansion and contraction, improving operation efficiency. When subjected to lateral collision, the elastic buffer inside the sliding rod 4 by the connecting rod 5 can reduce the impact force and also prevent the impact from causing injury to students.

[0024] Specifically, the rotating plate 85 is annular, and a sealing ring is fixedly installed on the outer surface of the sealing disc 82.

[0025] In this embodiment, the rotating plate 85 is annular and rotatably connected to the sealing disc 82, ensuring that the rotation of the internal threaded pipe 83 does not affect the airtightness of the sealing disc 82. The sealing ring on the outer surface of the sealing disc 82 further enhances the sealing performance of the sealing cavity 81, prevents air pressure leakage, ensures the effectiveness of air pressure drive, and at the same time reduces the friction between the sealing disc 82 and the inner wall of the sealing cavity 81, reducing operating resistance.

[0026] Specifically, a plug rod 841 is inserted into the inside of the socket 84, and a rubber sleeve is fixedly fitted onto the outer surface of the plug rod 841.

[0027] In this embodiment, after the insertion rod 841 is inserted into the insertion hole 84, the internal thread tube 83 can be rotated effortlessly through the lever principle, which makes it easy for the operator to quickly adjust the air pressure. The rubber tube on the outer surface of the insertion rod 841 increases the grip friction to prevent slipping during operation and improves hand comfort, making it especially suitable for scenarios with frequent adjustments (such as rapid installation during exam room setup).

[0028] The working principle and usage process of this utility model are as follows: Before use, the bottom of the sealing cavity 81 is under negative pressure. Therefore, sliding rod 1 4 retracts into the fixed cylinder 3, connecting rod 5 retracts into sliding rod 1 4, and sliding rod 2 6 retracts into connecting rod 5. During use, after connecting the tripod 1, support plate 2, and the main body 21 of the radio signal monitoring equipment, the tripod 1 is placed in the specified position. Then, the insertion rod 841 is inserted into the insertion hole 84, and the internal thread tube 83 is rotated counterclockwise. At this time, the internal thread tube 83 drives the rotating plate 85 to rotate inside the sealing disc 82, and drives the sealing disc 82 to slide downward. At this time, the inside of the sealing cavity 81... The bottom end is under high pressure, and through the vent pipe 86, the inside of the fixed cylinder 3 is also under high pressure. Since the inside of the fixed cylinder 3, the sliding rod 4, and the connecting rod 5 are in a connected state, and the connection is sealed by the sealing block 7, the high pressure inside the fixed cylinder 3 causes the sliding rod 4, the connecting rod 5, and the sliding rod 6 to automatically unfold. After unfolding, the connecting rod 5 surrounds the outside of the tripod 1, and the end of each sliding rod 6 rests against the ground, increasing the stability of the tripod 1. At the same time, it can also improve the stability of the tripod 1 after being hit by external impacts, thus enhancing the safety of the main body 21 of the radio signal monitoring equipment during use.

[0029] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
