Description
Technical Field
[0001] This invention relates to the field of signaling jammer technology, and more particularly to a signaling jammer for use in examination rooms. Background Technology
[0002] Signaling jammers are specialized jamming devices designed for mobile communication systems. Their core principle is to interfere with or block normal communication between mobile phones and base stations within a target area by simulating base station signaling or sending specific signals. Signaling jammers typically interfere with signals within a certain range through an antenna and are commonly used in scenarios such as examination rooms where signal jamming is required.
[0003] For example, Chinese patent CN215680972U discloses a shield for an external antenna, including a housing and a sealing cover. A support base is fixedly connected inside the housing, and the shield body is installed on the support base. Threaded rods are inserted through the four corners of the sealing cover. A support block is rotatably connected to the bottom end of the threaded rod. A limit block is fixedly connected to the bottom of the support block. A positioning plate corresponding to the position of the threaded rod is fixedly connected to the side wall of the housing. The positioning plate has a limit opening corresponding to the shape of the limit block. Two moving blocks are threadedly sleeved on the threaded rod, and the threads in the threaded openings of the two moving blocks are arranged in opposite directions.
[0004] The aforementioned device achieves quick assembly and disassembly of the cover plate through a snap-fit mechanism. However, when used in examination rooms, signaling jammers require prolonged use due to the long examination duration. Furthermore, signaling jammers need to simulate base station signaling, resulting in high power consumption and increased heat generation of the antenna and internal structure. The heat dissipation of the aforementioned device is inadequate. In addition, signaling jammers are often moved between different examination rooms during different examinations. Collisions or drops during movement can easily damage the antenna, and dust and other debris can easily accumulate on the antenna, affecting its performance. Summary of the Invention

It improves the efficiency and effectiveness of use. During the heat dissipation process, the mounting strip is vertically raised and lowered by a linear slide, so that the airflow blown from the exhaust pipe can be directed to different positions of the antenna body, thereby improving the heat dissipation effect of the antenna body. This invention, through the arrangement of a shielding shell assembly, a protective assembly, a heat dissipation and cleaning assembly, and an antenna assembly, not only achieves cleaning and heat dissipation of the antenna body, but also expands the heat dissipation area and improves the heat dissipation effect through the movable mounting strip and the air outlet pipe. By controlling the contact between the cleaning brush and the antenna body during lifting and lowering, and through the reciprocating movement of the sliding seat and the moving plate, it is possible to control the intensity of the airflow blown out from the air outlet pipe to make it work in conjunction with the cleaning of the cleaning brush, thereby improving the heat dissipation and cleaning effect. At the same time, the movement of the sliding seat can also drive the gear to reciprocate, thereby adjusting the gas guidance of the air guide plate. This can ensure the heat dissipation effect while preventing dust from spreading and affecting the examination environment. This invention reduces the space required for storing the antenna body by folding it in place. In the event of an accidental drop, the folded storage prevents the antenna body from breaking off at the ground, thus reducing the possibility of damage and improving the safety of the shield during use and transportation.

The upper end of the embedded block 39 is movably engaged with the lower end of the mounting strip 34. The motor 38 can drive the embedded block 39, the mounting strip 34 and the transmission rod 33 to rotate together, thereby adjusting the angle of multiple sets of antenna assemblies 4 and the linear slide 32. The linear slide 32 is used to drive the mounting strip 34 to move up and down, thereby allowing multiple sets of cleaning components 37 to move up and down on the outside of the antenna assembly 4. The gas inside the mounting strip 34 can be blown to the outer surface of the antenna assembly 4 through the air outlet pipe 36.
[0021] A top plate 12 is detachably and fixedly connected to the upper end of the shield housing 11. The signaling shielding module is set inside the shield housing 11. A fan 13 is fixedly connected inside the shield housing 11. A guide plate 14 is rotatably connected to the lower end of the shield housing 11. An air inlet is opened on one side of the shield housing 11. The fan 13 is set between the guide plate 14 and the air inlet. The fan 13 can accelerate the air circulation inside and outside the shield housing 11, thereby realizing the heat dissipation of the internal components of the signaling shield. The rotation of the guide plate 14 can guide the airflow of the fan 13 in different directions.
[0022] The protective component 2 includes two sets of first electric telescopic rods 21 fixedly connected at intervals to the upper end of the top plate 12. A sliding seat 24 is engaged and slidably connected to the upper end of the top plate 12, and two sets of sliding seats 24 are symmetrically arranged. A movable plate 25 is detachably fixedly connected between the two sets of sliding seats 24. One end of each set of first electric telescopic rods 21 is fixedly connected to one set of sliding seats 24. Through the extension and retraction of the two sets of first electric telescopic rods 21, the two sets of sliding seats 24 and the movable plate 25 can slide back and forth on the upper surface of the top plate 12.
[0023] A gear 15 is fixedly connected to the upper end of the air guide plate 14, and a rack 16 is fixedly connected to the lower end of a set of sliding seats 24. The gear 15 and the rack 16 are meshed together. A sliding hole is provided on the top plate 12 for the rack 16 to slide. When the sliding seat 24 moves back and forth, it can drive the air guide plate 14 to rotate back and forth through the rack 16 and the gear 15.
[0024] A mounting housing 22 is fixedly connected to the upper end of the top plate 12, and multiple sets of connecting holes are opened through the top plate 12 and the mounting housing 22. A fixing plate 23 is detachably connected to the upper end of the mounting housing 22. Multiple sets of rubber protective sleeves 28 are fixedly connected inside the mounting housing 22, and the rubber protective sleeves 28 are staggered with the connecting holes. There is a gap between the upper surface of the rubber protective sleeve 28 and the fixing plate 23, so that the air entering the shield housing 11 can enter the interior of the mounting housing 22 through the multiple sets of connecting holes.
[0025] The fixed plate 23 contacts the movable plate 25. The movable plate 25 has multiple sets of first clearance holes 26 extending vertically, and the fixed plate 23 has multiple sets of second clearance holes 27 extending vertically. The width, spacing, and number of the first clearance holes 26 and the second clearance holes 27 are the same. The multiple sets of second clearance holes 27 are respectively set above multiple sets of rubber protective sleeves 28. One end of multiple sets of connecting pipes 35 is fixedly connected to one side of the mounting housing 22. The connecting pipes 35 are provided with sufficient excess length for the installation strip 34 to move. The movement of the movable plate 25 can control whether the first clearance holes 26 and the second clearance holes 27 overlap.
[0026] The antenna assembly 4 includes an antenna base 44 fixedly connected to one side of the shield housing 11 and an antenna body 42 rotatably connected to the upper end of the antenna base 44. Both the antenna base 44 and the antenna body 42 are provided with multiple sets. The multiple sets of antenna bodies 42 pass through multiple sets of through holes on the mounting strip 34. When the mounting strip 34 rotates, it can drive the multiple sets of antenna bodies 42 to rotate.
[0027] Multiple antenna mounts 44 are spaced apart on one side of multiple rubber protective sleeves 28. After the antenna body 42 rotates 90 degrees, it can pass through the first clearance hole 26 and the second clearance hole 27 and be embedded inside the rubber protective sleeve 28. Two sets of collection frames 43 are detachably and fixedly connected to one side of the mounting block 31. The two sets of collection frames 43 are threaded together to form a storage frame. Multiple sets of partition tubes 41 are fixedly connected at intervals inside the storage frame. Multiple sets of antenna mounts 44 pass through the multiple sets of partition tubes 41. A baffle plate 49 is fixedly connected to the bottom of one set of collection frames 43 by a spring. One side of the baffle plate 49 is engaged and slidably connected to the collection frame 43. The rubber protective sleeve 28 can limit the position of the antenna body 42 and provide protection. The collection frame 43 is used to collect debris. The partition tube 41 is used to separate debris and antenna mounts 44. The baffle plate 49 is used to prevent air blown out from the inside of the rubber protective sleeve 28 from entering the collection frame 43. The collection frame 43 can be cleaned by separating the two sets of collection frames 43.
[0028] A first elastic ring 45 is fixedly connected to the outer surface of the antenna body 42. Four sets of elastic strips 46 are fixedly connected to the outer surface of the first elastic ring 45. A second elastic ring 47 is fixedly connected to the lower end of the four sets of elastic strips 46. An elastic plate 48 is fixedly connected between adjacent elastic strips 46, and the edge of the elastic plate 48 is also fixedly connected to the first elastic ring 45 and the second elastic ring 47. Dust and other debris falling from the antenna body 42 can be blocked by the elastic plate 48 and guided to a position away from the connection between the antenna body 42 and the antenna base 44, so as to avoid dust accumulation at the connection between the antenna base 44 and the antenna body 42 and affecting the use. The first elastic ring 45, elastic strips 46, second elastic ring 47 and elastic plate 48 can deform when the antenna body 42 is rotated and stored, and recover due to elasticity when the antenna body 42 is vertical, so as to adapt to different usage conditions of the antenna body 42.
[0029] The cleaning component 37 includes a second electric telescopic rod 371 embedded and fixedly connected to the inside of the through hole of the mounting strip 34. One end of the second electric telescopic rod 371 is fixedly connected to an arc plate 372. Both ends of the arc plate 372 are engaged and slidably connected to limit blocks 374. A cleaning brush 373 is fixedly connected to the inside of the arc plate 372. The outer surface of the antenna body 42 is in contact with the cleaning brush 373 and the two sets of limit blocks 374. The ends of the two sets of limit blocks 374 located at the same end of the two symmetrical sets of arc plates 372 are magnetically connected. When the arc plate 372 is pulled by the second electric telescopic rod 371, the cleaning brush 373 will first separate from the antenna body 42 due to the magnetic connection of the two sets of limit blocks 374. At this time, the four sets of limit blocks 374 can still limit the antenna body 42.
[0030] In this invention, when the signaling jammer is used for an extended period in an examination room, firstly, two sets of first electric telescopic rods 21 pull the sliding seat 24 so that the first clearance hole 26 and the second clearance hole 27 overlap. At this time, the antenna body 42 located inside the rubber protective sleeve 28 is exposed. Then, the motor 38 rotates both the embedding block 39 and the mounting strip 34 by 90 degrees. Since the antenna body 42 is clamped and fixed by the cleaning component 37, the linear slide 32 and multiple antenna bodies 42 can be rotated vertically simultaneously. Subsequently, the two sets of first electric telescopic rods 21 prevent the first clearance hole 26 from overlapping with the second clearance hole 27. Through the above, the angle of multiple antenna bodies 42 can be automatically adjusted without manual adjustment, avoiding errors caused by manual adjustment or misalignment between the antenna body 42 and the antenna seat 4. 4. Loose connections make it difficult for the antenna body 42 to maintain a vertical position, thus reducing the signal shielding effect. To improve efficiency and effectiveness, the fan 13 sends external air into the shield housing 11, which lowers the temperature of the shielding module inside the shield housing 11. Then, the air can enter the mounting strip 34 from the shield housing 11, the mounting housing 22 and the connecting pipe 35 and blow it to the outer surface of the antenna body 42 through multiple sets of air outlet pipes 36. This can achieve a common heat dissipation effect on the shielding module and the antenna body 42. During the heat dissipation process, the linear slide 32 drives the mounting strip 34 to rise and fall vertically, so that the airflow blown from the air outlet pipes 36 can blow to different positions of the antenna body 42, thereby improving the heat dissipation effect of the antenna body 42. During long-term use of the signaling jammer, dust and other debris in the surrounding environment can easily adhere to the outer surface of the antenna body 42, reducing the signal shielding effect. During the vertical reciprocating movement of the mounting strip 34, when the mounting strip 34 moves slowly upwards, the cleaning brush 373 is separated from the antenna body 42 by two sets of second electric telescopic rods 371. At this time, the antenna body 42 is limited by four sets of limiting blocks 374 and will not move. Simultaneously, the first clearance hole 26 and the second clearance hole 27 are aligned by two sets of first electric telescopic rods 21. At this time, air inside the mounting housing 22 can pass through the first clearance hole. With the air outlet cross-section increased by the second clearance hole 26 and the second clearance hole 27, the amount of air blown out from the air outlet pipe 36 decreases, preventing dust and debris on the antenna body 42 from being blown away and scattered. Simultaneously, the baffle plate 49 prevents the falling dust and dust in the collection frame 43 from being disturbed. When the mounting strip 34 moves slowly downwards, the two sets of second electric telescopic rods 371 cause the cleaning brush 373 to contact the outer surface of the antenna body 42, simultaneously causing the first clearance hole 26 and the second clearance hole 27 to no longer overlap. At this point, the cleaning brush 373 can scrape off debris from the outer surface of the antenna body 42. The object can fall into the collection frame 43 through the guide of the elastic plate 48 and be collected. At the same time, due to the smaller air outlet cross section, the amount of air blown out from the air outlet pipe 36 increases, which can continuously dissipate heat. When the sliding seat 24 moves back and forth, it can cause the air guide plate 14 to rotate back and forth through the rack 16 and gear 15, which can guide the air sent by the fan 13 to different positions inside the shield housing 11, improving the heat dissipation effect inside the shield housing 11. Through the arrangement of the shield housing assembly 1, the protective assembly 2, the heat dissipation and cleaning assembly 3 and the antenna assembly 4, not only is the cleaning of the antenna body 42 achieved, but also... For heat dissipation, the movable mounting strip 34 and the air outlet pipe 36 expand the heat dissipation area and improve the heat dissipation effect. By controlling the contact between the cleaning brush 373 and the antenna body 42 during lifting and lowering, and by the reciprocating movement of the sliding seat 24 and the moving plate 25, it is possible not only to control the intensity of the airflow blown out from the air outlet pipe 36 to make it work in conjunction with the cleaning of the cleaning brush 373, thus improving the heat dissipation and cleaning effect, but also to drive the gear 15 to reciprocate to adjust the gas direction of the air guide plate 14, so as to ensure the heat dissipation effect while avoiding dust from spreading and affecting the examination environment. After use, the mounting strip 34 is reset, and the embedding block 39 is re-embedded inside the mounting strip 34. Then, the first electric telescopic rod 21 makes the first clearance hole 26 and the second clearance hole 27 overlap. Then, the mounting block 31 makes the linear slide 32 and the mounting strip 34 rotate 90 degrees, so that multiple antenna bodies 42 are embedded inside the rubber protective sleeve 28, which can complete the storage of the antenna body 42. Then, the first clearance hole 26 and the second clearance hole 27 are staggered. At this time, the antenna body 42 is squeezed and fixed by the fixing plate 23 and the rubber protective sleeve 28, which can complete the storage of the antenna body 42, thereby reducing the space required for storing the antenna body 42. At the same time, if the antenna body 42 is accidentally dropped, since the antenna body 42 is folded and stored, it can avoid the situation where the end of the antenna body 42 is dropped and broken, thus improving the safety of the shield during use and transportation.
