[0020] Compared with the prior art, the present invention provides a communication signal jammer for confidential places, which has the following beneficial effects:

[0021] 1. The communication signal jammer for confidential places is equipped with a clamping assembly on the plug, so that when the plug is plugged into the socket, the clamping assembly can clamp and fix the two sides of the socket, which can effectively prevent the plug from being separated from the socket and ensure the use effect of the jammer.

[0022] 2. When the communication signal jammer in confidential places clamps and fixes the socket through the clamping assembly, the rubber pad placed between the socket and the clamping plate is stressed, and the air in the cavity of the rubber pad is introduced into the fixing tube through the air duct. The pneumatic assembly in the fixing tube works to make the lower cavity extract the air between the suction cup body and the bottom placement surface, so that the suction cup body is adsorbed on the lower placement surface to avoid shaking or falling of the jammer during use, thereby ensuring the use effect of the jammer. When the plug-in relationship between the plug and the socket is released, the suction cup body is automatically separated from the lower placement surface, reducing the operation steps and effectively improving the work efficiency of the staff.

[0023] 3. The communication signal jammer for confidential places, when the pneumatic component is working, the slide bar moves up and drives the rack plate to mesh with the driven gear, the driven gear drives the rotating rod to rotate, and when the rotating rod rotates, it drives the antenna from the storage state to the vertical working state, so that the jammer can be stored and placed conveniently when not in use, saving storage space. When in use, there is no need for staff to move it, reducing the operation steps, effectively improving the work efficiency of staff, and allowing the jammer to be put into use quickly.

[0024] 4. The communication signal jammer for confidential places can reduce the collision force between the jammer body and the lower placement surface when the jammer body is lowered by arranging a shock absorbing component between the bottom plate and the jammer body, thereby increasing the service life of the jammer and effectively preventing the internal parts of the jammer body from being damaged when placed. When the shock absorbing component is working, the piston discharges the air in the sleeve through the air port, and the discharged gas can blow to the lower placement surface of the suction cup body to prevent dust and impurities from adhering to the lower placement surface of the suction cup body, thereby improving the adsorption effect of the suction cup body and the lower placement surface and ensuring the stability of the jammer when used.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two components; for ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] Example:

[0037] Reference Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 A communication signal jammer device for a confidential place includes a jammer body 1 and also includes:

[0038] Antenna 2, multiple antennas 2 are provided, and multiple antennas 2 can be rotatably stored on the jammer body 1, and the jammer body 1 is provided with a receiving groove 101 for placing the antenna 2;

[0039] A bottom plate 3, the bottom plate 3 is placed at the bottom of the jammer body 1, and a shock absorbing component 4 is arranged between the bottom plate 3 and the jammer body 1;

[0040] A suction cup member 5, which is disposed at the bottom of the jammer body 1 and is used to fix the jammer body 1; and

[0041] A power cord 6 is connected to the jammer body 1 , and a plug 7 is provided at one end of the power cord 6 away from the jammer body 1 , on which a clamping assembly is provided.

[0042] Specifically, when the jammer body 1 is used, the bottom plate 3 at the bottom of the jammer body 1 is brought into contact with the lower placement surface, and the jammer body 1 naturally falls under the self-weight factor. The shock-absorbing component 4 buffers the fall of the jammer body 1 in this process to prevent it from being damaged by collision during placement. Then the staff inserts the plug 7 into the socket, and the clamping component clamps the sides of the socket in this process to fix the plug 7 in the socket to prevent the plug 7 from loosening and affecting the normal use of the jammer. When the clamping component works, it will drive the suction cup 5 to adsorb the lower placement surface to fix the jammer body 1 when it is used. The present invention has a simple structure and is easy to operate. It can effectively fix the plug 7 on the basis of the socket, fix the jammer body 1, and prevent the jammer from loosening and affecting the use effect of the jammer. After the plug 7 is plugged into the socket, the antenna 2 is changed from the storage state to the working state, reducing the staff's operation steps and allowing the jammer to be quickly put into use. When in use, the socket uses a special socket that matches the size of the plug 7 of the jammer.

[0043] Referring to Figure 2 and Figure 3 As a preferred technical solution of the present invention, the plug 7 includes a base body 701 fixedly connected to the power cord 6 and pins 702 arranged on the base body 701; specifically, the plug 7 is inserted into the socket jack through the pins 702 to complete the power supply to the jammer.

[0044] Referring to Figure 1 、 Figure 2 and Figure 3 As a preferred technical solution of the present invention, the clamping assembly includes a fixed block 8 fixedly arranged on the plug 7. A fixed rod 801 is arranged on the fixed block 8. Toggle plates 802 are arranged at both ends of the fixed rod 801. A torsion spring 8011 is sleeved on the fixed rod 801. Two ends of the torsion spring 8011 are respectively abutted against the fixed block 8 and the toggle plate 802. Concave holes 8021 are formed in the toggle plates 802. A movable rod 803 is movably connected in the concave holes 8021. A movable plate 804 slidably arranged on the plug 7 is connected to the movable rod 803. A clamping plate 805 is arranged at one end of the movable plate 804 away from the movable rod 803. A rubber pad 806 is arranged on the clamping plate 805.

[0045] Furthermore, a slider 8041 is fixedly arranged on the movable plate 804, and a chute 703 for the slider 8041 to slide is formed in the plug 7.

[0046] Specifically, when the staff inserts the plug 7 into the socket, first, a force is applied to the toggle plates 802 on both sides of the plug 7. The toggle plates 802 rotate relative to the fixed rod 801, so that the two toggle plates 802 approach each other. When the toggle plates 802 rotate, the movable plate 804 is driven by the movable rod 803 to slide on the plug 7. The movable plate 804 drives the slider 8041 to slide in the chute 703, so that the clamping plates 805 on both sides of the plug 7 move away from each other. Subsequently, the plug 7 is inserted into the socket. The staff no longer presses the toggle plates 802. The toggle plates 802 rotate back under the action of the torsion spring 8011, so that the clamping plates 805 at the ends of the two movable plates 804 approach each other, clamping and fixing the two side edges of the socket, effectively preventing the plug 7 from loosening and ensuring the normal use of the jammer. The rubber pad 806 arranged on the clamping plate 805 prevents the socket from being damaged when clamped, and anti-slip lines can be arranged on the rubber pad 806 to enhance the anti-slip effect.

[0047] Referring to Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 and Figure 6 As a preferred technical solution of the present invention, the sucker member 5 includes a fixed tube 501 fixedly connected to the jammer body 1. A sucker body 502 is arranged at the bottom of the fixed tube 501. A pneumatic assembly for changing the suction and release states of the sucker body 502 is arranged in the fixed tube 501.

[0048] Further, the pneumatic assembly includes a partition plate 5011 fixedly arranged in the fixed tube 501. The partition plate 5011 divides the fixed tube 501 into an upper cavity 5012 and a lower cavity 5013. Air holes 15 are formed in both the upper cavity 5012 and the lower cavity 5013. An air guide tube 12 is arranged between the upper cavity 5012 and the rubber pad 806, and a through hole 13 is arranged between the lower cavity 5013 and the suction cup body 502.

[0049] Further, an upper plug plate 9 is slidably connected in the upper cavity 5012. A sliding rod 10 slidably connected in the fixed tube 501 is arranged on the upper plug plate 9. A lower plug plate 11 slidably connected in the lower cavity 5013 is arranged at the bottom of the sliding rod 10. A first elastic element 1001 is sleeved outside the sliding rod 10, and two ends of the first elastic element 1001 are respectively connected to the lower plug plate 11 and the partition plate 5011.

[0050] Further, a cavity 8061 communicated with the air guide tube 12 is arranged on the rubber pad 806, and the air guide tube 12 is adhered to the power cord 6.

[0051] Specifically, when the clamping assembly clamps the socket, the rubber pad 806 placed between the socket and the clamping plate 805 is stressed. The air in the cavity 8061 of the rubber pad 806 is introduced into the fixed tube 501 through the air guide tube 12. One end of the air guide tube 12 far from the rubber pad 806 can be divided into multiple air tubes to guide air into multiple fixed tubes 501. The pneumatic assembly in the fixed tube 501 works. The upper plug plate 9 in the upper cavity 5012 is stressed and moves upward. The upper plug plate 9 drives the sliding rod 10 and the lower plug plate 11 at the bottom end of the sliding rod 10 to move upward. The lower side of the lower cavity 5013 is in negative pressure, so that the lower cavity 5013 extracts the air between the suction cup body 502 and the lower placement surface through the through hole 13, enabling the suction cup body 502 to adsorb on the lower placement surface, avoiding the shakiness or dropping of the jammer during use and ensuring the use effect of the jammer. When the plug 7 is disconnected from the socket, the rubber pad 806 is no longer squeezed. The first elastic element 1001 pushes the plug plate to reset. The lower cavity 5013 discharges the previously extracted air back into the lower side of the suction cup body 502 through the through hole 13, and the suction cup body 502 automatically separates from the lower placement surface, facilitating the reduction of operation steps and effectively improving the working efficiency of the staff.

[0052] Refer to Figure 1 and Figure 7As a preferred technical solution of the present invention, a rack plate 1002 is provided on the top of the slide bar 10, and a driven gear 141 is meshed and connected on the outer side of the rack plate 1002. A rotating rod 14 rotatably arranged on the jammer body 1 is connected to the driven gear 141, and the rotating rod 14 is fixedly connected to one end of the antenna 2; specifically, when the pneumatic assembly is working, the slide bar 10 moves up and drives the rack plate 1002 to mesh and transmit with the driven gear 141, and the driven gear 141 drives the rotating rod 14 to rotate. When the rotating rod 14 rotates, it drives the antenna 2 from the storage state to the vertical working state, which is convenient for the jammer to be stored and placed when not in use, saving storage space, and no staff is required to move it when in use, reducing the operation steps, effectively improving the work efficiency of the staff, and allowing the jammer to be quickly put into use.

[0053] Reference Figure 1 , Figure 4 and Figure 5 As a preferred technical solution of the present invention, the shock absorbing component 4 includes a sleeve 401 fixedly mounted on the bottom plate 3, a piston 402 is slidably connected in the sleeve 401, a second elastic element 403 is arranged between the piston 402 and the inner wall of the sleeve 401, and a movable rod 404 is arranged at one end of the piston 402 away from the second elastic element 403, the movable rod 404 is fixedly connected to the disruptor body 1, and an air port 301 connected to the inner cavity of the sleeve 401 is opened on the bottom plate 3, and the air port 301 faces the suction cup member 5; specifically, by arranging the shock absorbing component 4 between the bottom plate 3 and the disruptor body 1, when the device is used, the bottom plate 3 at the bottom of the disruptor body 1 is in contact with the lower placement surface, and the disruptor body 1 falls naturally under the self-weight factor, and the movable rod 404 is fixedly connected to the disruptor body 1. The movable rod 404 drives the piston 402 to move downward in the sleeve 401, and the second elastic element 403 is deformed by the force. In this process, the shock absorbing component 4 buffers and relieves the force of the fall of the jammer body 1, which can reduce the collision force between the jammer body 1 and the lower placement surface when the jammer body 1 is lowered, thereby increasing the service life of the jammer and effectively preventing the internal parts of the jammer body 1 from being damaged when it is placed. When the shock absorbing component 4 is working, the piston 402 discharges the air in the sleeve 401 through the air port 301, and the discharged gas can blow the lower placement surface of the suction cup body 502 to prevent dust and impurities from adhering to the lower placement surface of the suction cup body 502, thereby improving the adsorption effect of the suction cup body 502 and the lower placement surface, and ensuring the stability of the jammer.

[0054] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
