Description
Technical Field
[0001] This utility model relates to the field of signal jammer technology, and in particular to a wall-mounted signal jammer. Background Technology
[0002] A wall-mounted signal jammer is a device that blocks or disrupts the normal reception and transmission of legitimate radio communication equipment by emitting interference signals within a specific frequency range. Its working principle is based on the superposition principle of radio waves; that is, when two or more electromagnetic waves exist simultaneously in the same space, the stronger signal will suppress the weaker signal. Signal jammers are often used in school examinations.
[0003] Wall-mounted signal jammers are usually fixed to the wall with screws or strong adhesive. However, when there are no exams, in order to prevent students from damaging the signal jammers during breaks, they need to be disassembled and then reinstalled when there are exams. Current technology uses screws and glue for fixing, which is very inconvenient to install and disassemble. In addition, this installation method requires the device to be close to the wall, which is not conducive to heat dissipation. Utility Model Content
[0004] The technical problem to be solved by this utility model is that the existing technology uses screws and glue for fixing, which is very inconvenient to install and disassemble, and this installation method requires the device to be close to the wall, which is not conducive to heat dissipation.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a wall-mounted signal jammer is provided, including a mounting plate and a signal jammer body. Two connecting blocks are fixedly connected to one side of the surface of the mounting plate. Slots are provided on the surface of the two connecting blocks near the signal jammer body. Two insert plates are fixedly connected to the surface of the signal jammer body near the mounting plate. The two insert plates are slidably installed into the two slots respectively.
[0006] Each of the two connecting blocks has a quick-connect assembly on one side of its surface that is far apart from each other, which can quickly fix the two inserts into the two slots. Each of the two connecting blocks has two mounting holes on the side of its surface that is close to the signal jammer body, and each of the two mounting holes has a pop-out assembly inside.
[0007] Preferably, the quick-connect assembly includes a slide cylinder, which is fixedly connected to one side of the surface of the connecting block. A slide plate is slidably connected to the inner side wall of the slide cylinder. A locking block is fixedly connected to the side of the slide plate near the surface of the connecting block. One end of the locking block slides through the connecting block and extends into the interior of the slot. A locking hole is provided through one side of the surface of both insert plates. The position and size of the locking block and the locking hole are matched. A connecting rod is fixedly connected to the side of the slide plate away from the locking block. One end of the connecting rod slides through and extends to the outside of the slide cylinder.
[0008] Preferably, a lever is provided on one side of the surface of the slide cylinder, and an installation groove is provided at the bottom of the lever. One end of the connecting rod is installed inside the installation groove and is movably connected by a pin. When the lever is turned, the lever pulls the connecting rod, and the connecting rod drives the slide plate and the locking block to move in the direction of the lever, so that the locking block is moved out of the locking hole.
[0009] Preferably, a first spring is sleeved on the outside of the connecting rod. One end of the first spring is fixedly connected to one side of the surface of the slide plate, and the other end of the first spring is fixedly connected to one side of the inner surface of the slide cylinder. When one end of the locking block slides across the surface of the insert plate and engages with the locking hole, the spring rebound can push the locking block into the locking hole.
[0010] Preferably, the mounting plate has multiple fixing holes along its perimeter on one side of its surface for pre-fixing the mounting plate to the wall.
[0011] Preferably, the signal jammer body has two heat dissipation windows on the side of the surface near the mounting plate, and the inner sidewalls of the two heat dissipation windows are fixedly installed with dustproof nets to prevent dust from entering the interior of the signal jammer body.
[0012] Preferably, the pop-out component includes a top post, the outer side wall of which is slidably connected to the inner side wall of the mounting hole, one end of which is fixedly connected to a second spring, one end of which is fixedly connected to the inner bottom of the mounting hole, and the other end of which extends through to the outside of the mounting hole and is fixedly connected to a top plate. When disassembling, after the locking block slides out of the locking hole, the rebound force of the second spring drives the top post and the top plate to push the signal jammer body, slightly popping the insert plate out of the slot.
[0013] The beneficial effects of this utility model are as follows:
[0014] This invention utilizes components such as slots, insert plates, and levers. The mounting plate is fixed to the wall. The signal jammer body is held in hand and the insert plate is inserted into the slot. A locking block slides across the surface of the insert plate and engages with a locking hole, fixing the position of the slot and insert plate. The signal jammer body is then fixed to the mounting plate. Moving the lever pulls the sliding plate and locking block, causing the locking block to slide out of the locking hole. A pop-out component pushes the signal jammer body, slightly ejecting the insert plate from the slot, allowing the signal jammer body to separate from the mounting plate. Compared to existing technologies that fix the signal jammer body to the wall with screws or glue, this design is more convenient for installation and disassembly. Furthermore, the larger gap between the two connecting blocks ensures better heat dissipation as the signal jammer body is not tightly pressed against the wall. Attached Figure Description

[0021] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.
[0022] Please see Figures 1 to 3 A wall-mounted signal jammer includes a mounting plate 1 and a signal jammer body 2. Two connecting blocks 3 are fixedly connected to one side of the surface of the mounting plate 1. Each of the two connecting blocks 3 has a slot 4 on the side of the surface of the signal jammer body 2 near the surface of the mounting plate 1. Two insert plates 5 are fixedly connected to the side of the signal jammer body 2 near the surface of the mounting plate 1. The two insert plates 5 are slidably installed into the two slots 4 respectively.
[0023] Each of the two connecting blocks 3 has a quick-connect component on the side of its surface that is far apart from each other, which can quickly fix the two insert plates 5 into the two slots 4. Each of the two connecting blocks 3 has two mounting holes on the side of its surface that is close to the signal jammer body 2, and each of the two mounting holes has a pop-out component inside.
[0024] like Figures 1 to 5As shown, the pop-out component includes a top post 13. The outer wall of the top post 13 is slidably connected to the inner wall of the mounting hole. One end of the top post 13 is fixedly connected to a second spring 14. One end of the second spring 14 is fixedly connected to the inner bottom of the mounting hole. The other end of the top post 13 extends through to the outside of the mounting hole and is fixedly connected to a top plate 15. When disassembling, after the locking block 8 slides out of the locking hole 501, the rebound force of the second spring 14 drives the top post 13 and the top plate 15 to push the signal jammer body 2, and slightly pops the insert plate 5 out of the slot 4. Two heat dissipation windows are opened on the side of the signal jammer body 2 near the mounting plate 1. Dustproof nets 201 are fixedly installed on the inner wall of the two heat dissipation windows to prevent dust from entering the interior of the signal jammer body 2. Multiple fixing holes 101 are opened around one side of the surface of the mounting plate 1 for pre-fixing the mounting plate 1 to the wall.
[0025] like Figures 1 to 4 As shown, the quick-connect assembly includes a slide cylinder 6, which is fixedly connected to one side of the surface of the connecting block 3. A slide plate 7 is slidably connected to the inner wall of the slide cylinder 6. A locking block 8 is fixedly connected to the side of the slide plate 7 near the surface of the connecting block 3. One end of the locking block 8 slides through the connecting block 3 and extends into the interior of the slot 4. A locking hole 501 is provided through one side of the surface of each of the two insert plates 5. The locking block 8 and the locking hole 501 are matched in position and size. A connecting rod 9 is fixedly connected to the side of the slide plate 7 away from the locking block 8. One end of the connecting rod 9 slides through and extends to the outside of the slide cylinder 6. A lever 10 is provided on one side of the surface of the slide cylinder 6. The bottom of the lever 10 is open... A mounting groove 11 is provided. One end of the connecting rod 9 is installed inside the mounting groove 11 and is movably connected by a pin. When the lever 10 is turned, the lever 10 pulls the connecting rod 9. The connecting rod 9 drives the slide plate 7 and the locking block 8 to move in the direction of the lever 10, so that the locking block 8 moves out of the locking hole 501. A first spring 12 is sleeved on the outside of the connecting rod 9. One end of the first spring 12 is fixedly connected to one side of the surface of the slide plate 7, and the other end of the first spring 12 is fixedly connected to one side of the inner surface of the slide cylinder 6. When one end of the locking block 8 slides across the surface of the insert plate 5 and engages with the locking hole 501, the first spring 12 rebounds and can push the locking block 8 into the locking hole 501.
[0026] In use, the mounting plate 1 is pre-fixed to the wall. When the signal jammer body 2 needs to be installed for an exam, the user holds the signal jammer body 2 and aligns the insert plate 5 with the slot 4, so that the insert plate 5 is installed inside the slot 4. The connecting block 3 presses the ejection component, the insert plate 5 presses the locking block 8, and the locking block 8 drives the sliding plate 7, causing the sliding plate 7 to compress the first spring 12 and slide on the inner wall of the sliding cylinder 6. The end of the locking block 8 slides across the surface of the insert plate 5 and matches and engages with the locking hole 501, thus fixing the insert plate 5 inside the slot 4. At this time, the signal jammer body 2 is fixedly installed on the mounting plate 1. When the test is complete and signal shielding is no longer needed, move the two levers 10. Lever 10 pulls the connecting rod 9, which in turn moves the slide plate 7 and the locking block 8 toward the lever 10. The locking block 8 can then slide out of the locking hole 501. At this time, the rebound force of the second spring 14 drives the top column 13 and the top plate 15 to push the signal jammer body 2, slightly popping the insert plate 5 out of the slot 4. Compared with the existing technology of fixing the signal jammer body 2 to the wall with bolts or glue, installation and disassembly are more convenient. Moreover, there is a larger gap between the two connecting blocks 3, so the signal jammer body 2 will not be in close contact with the wall, resulting in better heat dissipation.
