[0004] When using the strong electromagnetic pulse comprehensive protection device, it is mainly used to form the shielding material of the protective shell to shield the strong electromagnetic pulse. Therefore, in actual use, the shielding material will be deformed and damaged when impacted, that is, when subjected to external force, the external force is directly applied to the protective device, which not only affects the shielding effect and service life of the protective device.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] See also Figure 1-Figure 5 The utility model provides a technical solution: a strong electromagnetic pulse comprehensive protection reinforcement device, including a protective shell 1, a fixing plate 2 is arranged inside the fixing plate 2, and the fixing plate 2 and the threading plate 3 are fitted with each other, and a threading hole is opened in the middle of the threading plate 3; a reinforcement rod 5 is fitted in a cylindrical groove starting from the side of the fixing plate 2; a fixing screw 4 is penetrated on the threading plate 3, and the fixing screw 4 is connected to the protective shell 1 through a threaded hole opened on the protective shell 1; the fixing plate 2 is arranged as a "mouth"-shaped plate structure, and two fixing plates 2 are symmetrically arranged about the center of the protective shell 1.

[0022] When it is necessary to perform strong electromagnetic pulse protection on the electronic equipment, the electronic equipment is placed in the middle position inside the protective shell 1, and then the threading plate 3 is moved toward the direction close to the fixed plate 2, and the wires of the electronic equipment are passed through the middle position of the threading plate 3 (a through hole for the wires to pass through is provided in the middle position of the threading plate 3, and the diameter of the through hole is slightly larger than the diameter of the wire), and then the fixing screw 4 is passed through the plate-like structure on the side of the threading plate 3, and then the fixing screw 4 is rotated, and the fixing screw 4 begins to be connected with the threaded hole provided on the protective shell 1 and the protective shell 1, therefore, the threading plate 3 can be tightly fitted to the side of the fixed plate 2 through the fixing screw 4, and at this time, the protective shell 1 and the threading plate 3 can realize strong electromagnetic pulse shielding of the electronic equipment (the protective shell 1 and the threading plate 3 are set to metal materials that can shield strong electromagnetic pulses, which can be copper, aluminum, stainless steel, etc.), and a reinforcement rod 5 is provided on the threading plate 3, and the reinforcement rod 5 can be used to support and protect the interior of the protective shell 1.

[0023] A push spring 6 is fitted on the outer surface of the protective shell 1, and a reinforcement plate 7 is provided on the upper end of the push spring 6, and a limit assembly 8 is provided on the lower end of the reinforcement plate 7, and the limit assembly 8 is arranged through the protective shell 1; the reinforcement plate 7 is arranged as a square plate structure, and the reinforcement plate 7 is elastically connected with the protective shell 1 through the push spring 6; the limit assembly 8 includes a sliding plate 801 and a receiving plate 802, and the sliding plate 801 and the reinforcement plate 7 are interconnected, and a long strip groove is opened on the side of the sliding plate 801, and the receiving plate 802 is installed on the inner surface of the protective shell 1; the limit assembly 8 also includes a positioning rod 803 and a positioning spring 804, and the positioning rod 803 is arranged through the receiving plate 802, and the positioning rod 803 is slidably connected with the sliding plate 801 through the long strip groove opened on the sliding plate 801, the positioning spring 804 is fixedly installed on the sliding plate 801, and the positioning spring 804 and the positioning rod 803 are interconnected.

[0024] When the outside of the protective shell 1 is hit by an external force, the reinforcement plate 7 starts to move towards the protective shell 1. Because the push spring 6 is installed at the lower end of the reinforcement plate 7, the push spring 6 starts to be squeezed and deformed. That is, under the action of the push spring 6, shock absorption protection can be achieved between the reinforcement plate 7 and the protective shell 1 to prevent the external force from being directly applied to the protective shell 1. As the reinforcement plate 7 moves towards the protective shell 1, the sliding plate 801 installed on the reinforcement plate 7 starts to slide on the protective shell 1, and the positioning rod 803 also starts to slide on the sliding plate 801. When the push spring 6 is deformed due to overwork, the positioning rod 803 is pulled, and the positioning rod 803 begins to move away from the receiving plate 802. Because the positioning rod 803 is equipped with a positioning spring 804, the positioning spring 804 begins to be stretched and deformed until the positioning rod 803 no longer fits the long groove on the side of the positioning rod 803, and then the reinforcement plate 7 is pulled upward, and the reinforcement plate 7 drives the sliding plate 801 to move away from the protective shell 1, so that the push spring 6 and the reinforcement plate 7 can be disassembled and replaced.

[0025] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
