Problems solved by technology

[0002] The signal jammer is aimed at the uplink and downlink channels of the mobile phone system. It uses frequency multiplication, frequency division, frequency hopping filtering and other technologies to analyze the required shielding frequency, customize a spherical shielding space according to the power of the jammer, and automatically form within the specified range. Shielding the magnetic field, when the jammer is in the working state, it can invalidate the signal sending and receiving function of the mobile phone within the specified range, making it impossible to dial out and dial in, so as to achieve the purpose of mandatory disabling. The existing signal jammers are generally placed with The direct contact between the surfaces will easily make the bottom of the shielding device damp and affect the service life, and the shielding device cannot be placed stably when placed on an uneven surface, and it is not convenient to heat the bottom of the shielding device during work, which will further affect The service life of the jammer, and it is not convenient for users to carry the jammer

Embodiment 1

[0026] The present invention provides such Figure 1-3 The shown external signal shielding device for a data transmission system includes a shielding case 1, the outer wall of the shielding case 1 is evenly connected with an antenna 2, and the bottom of the shielding case 1 is connected with a base 3, so The top of the base 3 is located below the shield housing 1 and is provided with a groove 4, the interior of the groove 4 is equidistantly equipped with a fan 7, and the bottom of the shield housing 1 is located on both sides of the groove 4. There is a bump 5, and the top of the base 3 is provided with a limiting groove 6 at the outer position corresponding to the bump 5, and a fixed sleeve 8 is respectively connected to the bottom of the base 3 near the four corners. The inner side of the bottom of the fixed sleeve 8 is connected with an externally threaded column 9, and the bottom end of the externally threaded column 9 is connected with a rubber block 10, and the front and...

Embodiment 2

[0037] An external signal shielding method for a data transmission system, including the external signal shielding device for a data transmission system, and also includes the following method:

[0038] S1: By connecting the base 3 at the bottom of the shielding shell 1, and setting a bump 5 at the bottom of the shielding shell 1, the top of the base 3 is provided with a limiting groove 6 at the outer position corresponding to the bump 5, and the bump 5 and the limiting groove 6 are both in the shape of a "T". The shielding shell 1 and the base 3 are slidably connected through the limiting groove 6, which is convenient for the shielding shell 1 to be stably installed above the base 3, and the shielding shell 1 and the base 3 are slidably connected. An accommodating space is enclosed between the bases 3;

[0039] S2: a groove 4 is provided on the top of the base 3 below the shield housing 1, and the groove 4 accommodates signal transmission lines for the data transmission syste...

Abstract

The invention relates to the technical field of signal shielding and discloses an external signal shielding device and method for a data transmission system. The device comprises a shielding device outer shell, the outer side wall of the shielding device outer shell is uniformly connected with antennas, the bottom of the shielding device outer shell is connected with a base, the top of the base isprovided with a groove below the shielding device outer shell, fans are mounted at equal intervals in the groove, and the bottom end of the shielding device outer shell is provided with convex blockson two sides of the groove. Direct contact between a shielding device and a placement surface is avoided, the problem of influences on service life due to dampness of the bottom of the shielding device is reduced, stable placement of the shielding device placed on a non-leveled placement surface is facilitated, convenience in heat dissipation treatment of the bottom of the shielding device in operation is achieved, damages caused by excessive heat are prevented, the service life of the shielding device is prolonged, a user can carry with the shielding device conveniently, and a handle is retracted in placement to reduce occupied space.
