Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of recording jammers, in particular to a portable anti-recording device. Background Art
[0002] A recording jammer is a device designed to block recordings in specific environments. It can effectively interfere with digital and tape recorders, cameras, and eavesdropping devices. By outputting white noise outside the human hearing frequency range, the recorder or recorder only records a buzzing noise, preventing the speaker's conversation from being recorded. Even after post-processing, the recorded sound cannot be restored to the speaker's voice, effectively protecting the conversation from being secretly recorded. As is well known, existing anti-recording devices are designed to be lightweight and compact for portability.
[0003] The portable anti-recording jammers currently in use are generally placed in pockets for use. In the summer when people wear less clothes, if the portable anti-recording jammer is placed in a pocket, it is easy to be discovered by other people, which is not conducive to the use of the user. Moreover, when it is not convenient to place it in a pocket for use, it cannot be fixed on other parts of the body for use, and its applicability is low. Therefore, a portable anti-recording device is proposed to address the above problems. Utility Model Content

[0024] As a further improvement of the present invention, Figure 1 、 Figure 2 and Figure 3 As shown, the reeling mechanism includes a bearing 12 fixedly connected to the anti-recording jammer main body 1, a reeling rod 9 fixedly connected to the inner side of the bearing 12, and the reeling rod 9 is rotatably connected to the top of the anti-recording jammer main body 1, and the outer side of the top of the reeling rod 9 is spirally connected to a limit ring 10, and the limit ring 10 is in contact with the anti-recording jammer main body 1. When the anti-recording jammer main body 1 is not convenient to be placed in a pocket for use, the Velcro A side 7 and the Velcro B side 8 are pulled out from the inner side of the anti-recording jammer main body 1, and then the Velcro A side 7 and the Velcro B side 8 are used to reel the anti-recording jammer main body 1 out of the pocket. The surface 8 fixes the anti-recording jammer main body 1 on the user's leg, and at the same time, the anti-recording jammer main body 1 is covered and hidden by the pants, thereby improving the applicability of the device. According to the thickness of the user's legs, the use length of the user's Velcro A surface 7 and the Velcro B surface 8 can be adjusted by the winding rod 9 to meet the usage needs of different users. When the Velcro A surface 7 and the Velcro B surface 8 are not in use, they are retracted into the interior of the anti-recording jammer main body 1, and a section is exposed to facilitate the user's pulling, thereby facilitating the user's carrying and use.
[0025] As a further improvement of the present invention, Figure 1 and Figure 3 As shown, the outer sides of the Velcro A side 7 and the Velcro B side 8 are both provided with anti-slip frames 6, and the anti-slip frames 6 are fixedly connected to the anti-recording jammer main body 1, and the Velcro A side 7 and the Velcro B side 8 can slide relative to the anti-slip frames 6, and the friction between the anti-slip frames 6 and the Velcro A side 7 and the Velcro B side 8 can achieve limited fixation of the Velcro A side 7 and the Velcro B side 8, preventing the Velcro A side 7 and the Velcro B side 8 from moving around arbitrarily.
[0026] As a further improvement of the present invention, Figure 1 and Figure 3 As shown, the anti-slip frame 6 is made of a rubber frame, which can improve the friction between the anti-slip frame 6 and the Velcro A surface 7 and the Velcro B surface 8.

The support net 5 plays a role in supporting and fixing the sweat-absorbent cotton 4, thereby improving the stability of the sweat-absorbent cotton 4 during use. When sweat appears, the sweat-absorbent cotton 4 can absorb the sweat, thereby preventing the sweat from affecting the circuit board 11 and other electronic components of the anti-recording interference device main body 1.
[0029] Working process: When the anti-recording jammer body 1 is not convenient to be placed in a pocket for use, the user first separates the limiting ring 10 from the anti-recording jammer body 1, and then pulls the Velcro A side 7 and the Velcro B side 8, and pulls the Velcro A side 7 and the Velcro B side 8 out of the interior of the anti-recording jammer body 1 to a suitable length, so that the pulled-out length is suitable for the needs of one's legs, and then makes the limiting ring 10 fit tightly with the anti-recording jammer body 1, and realizes the limiting fixation of the winding rod 9 by the friction between the limiting ring 10 and the anti-recording jammer body 1, and then uses the Velcro The A side 7 and the Velcro B side 8 fix the anti-recording jammer main body 1 to the user's leg, and at the same time, the anti-recording jammer main body 1 is concealed by the pants, thereby improving the applicability of the device. The air holes 2 and the ventilation holes 3 can reduce the contact area between the anti-recording jammer main body 1 and the leg, making the contact part of the anti-recording jammer main body 1 and the leg ventilated, reducing the occurrence of sweat, and improving the comfort of the user. When sweat appears, the sweat-absorbing cotton 4 can absorb the sweat to prevent the sweat from affecting the circuit board 11 and other electronic components of the anti-recording jammer main body 1.
