[0002] Electromagnetic pulse signal acquisition devices, as an important component of modern electronic measurement and monitoring systems, are widely used in fields such as communications, power, and aerospace. They are used to capture and analyze weak electromagnetic pulse signals in the environment, playing an irreplaceable role in monitoring equipment status, diagnosing faults, and studying electromagnetic compatibility. These devices convert electromagnetic pulses into electrical signals through high-precision sensors, and then transmit them to the data processing system after analog-to-digital conversion, providing valuable data support for scientific research and industrial production.

[0003] In practical applications, electromagnetic pulse signal acquisition devices often face challenges from complex and ever-changing environmental conditions, such as in machine manufacturing workshops or earthquake-prone areas. The performance of the device is easily affected. External vibrations and shocks, as well as the vibration of the device itself, can not only cause the connection between the sensor and the circuit to become loose, affecting the accuracy of the detection value, but may also cause micro-damage to the internal components. Over a long period of time, the main structure of the device may be severely damaged, which may lead to the risk of data loss or complete failure of the equipment. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides an electromagnetic pulse signal acquisition device with a protective structure to solve the aforementioned problems.

[0005] This utility model is implemented as follows:

[0006] An electromagnetic pulse signal acquisition device with a protective structure includes a protective box and an electromagnetic pulse meter body. The protective box has a front cover hinged to its front side, and a wire groove is provided in the center of the front side of the front cover. A heat dissipation unit is provided at the center of the top of the protective box, and two handles are symmetrically arranged on the left and right sides of the top.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0023] like Figure 1-2 As shown, this utility model provides an electromagnetic pulse signal acquisition device with a protective structure, including a protective box 10 and an electromagnetic pulse meter body 18. A front cover 11 is provided on the front side of the protective box 10, and the bottom of the front cover 11 is hinged to the protective box 10. The front side of the front cover 11, near the top, is fixed to the protective box 10 by a hand-tightening bolt, which can be quickly tightened before opening or closing. A wire groove 1101 is provided in the center of the front side of the front cover 11. A heat dissipation unit 14 is provided at the center of the top of the protective box 10, and two handles 12 are symmetrically provided on the left and right sides of the top. Foot supports 13 are provided at the four corners of the bottom of the protective box 10. The handles 12 and foot supports 13 facilitate the transport of the protective box 10. Once the electromagnetic pulse meter body 18 is assembled in the protective box 10, it can be stored there for a long time and used as needed. The bottom of the protective box 10 is open, and a drawer assembly 15 is provided inside the protective box 10 near the bottom. A placement plate 16 is movably mounted on the top of the drawer assembly 15. Two elastic clamps 1604 are symmetrically arranged on the left and right sides of the top of the placement plate 16. The electromagnetic pulse instrument body 18 is clamped between the two elastic clamps 1604. The probe of the electromagnetic pulse instrument body 18 is threaded through the wire groove 1101. A button for controlling the heat dissipation unit 14 is provided on the right side of the front of the protective box 10. Before assembly, open the front cover 11 and pull out the drawer assembly 15. At this time, the electromagnetic pulse instrument body 18 is embedded between the two elastic clamps 1604. Then close the drawer and thread the probe wire on the electromagnetic pulse instrument body 18 through the wire groove 1101 for normal use. The elastic connecting post 17 between the placement plate 16 and the drawer assembly 15 ensures that it is not affected by external environmental vibration and can also reduce its own vibration. At the same time, the setting of the heat dissipation unit 14 ensures that it can dissipate heat normally when used in the protective box 10, avoiding heat accumulation and damage to the equipment.

[0024] like Figure 2-4 As shown, the drawer assembly 15 includes a drawer plate 1501 and two drawer slides 1502. The drawer slides 1502 are fixed to the inner side wall of the protective box 10 near the bottom, and the movable ends of the two drawer slides 1502 are fixed to the left and right sides of the drawer plate 1501.

[0025] Furthermore, elastic connecting posts 17 are provided near the four corners of the top of the drawer panel 1501. The top of the placement plate 16 has a movable hole 1601 extending in the direction of the elastic connecting post 17. The elastic connecting post 17 is movably disposed in the movable hole 1601. The elastic connecting post 17 includes an anchor rod 1701. A limiting piece 1702 is provided at the top of the anchor rod 1701. A first limiting ring 1703 is provided at the bottom edge of the limiting piece 1702. A second limiting ring 1704 of the same size and coaxial with the first limiting ring 1703 is provided at the top of the drawer panel 1501. A first abutting spring 1705 is provided between the limiting piece 1702 and the placement plate 16. A second abutting spring 1706 is provided between the drawer panel 1501 and the placement plate 16. The two limiting rings ensure that the abutting spring is fixed in position when compressed, increasing the stability of the elastic connecting post 17 when supported.

[0026] It should be noted that the elastic force of the second abutment spring 1706 is greater than that of the first spring. The main function of the second abutment spring 1706 is to provide a flexible connection between the placement plate 16 and the drawer plate 1501, while the first abutment spring 1705 is to increase the rebound. The combination of the two provides a better shock absorption effect for the electromagnetic pulse instrument body 18.

[0027] In a preferred embodiment, a first rubber ring 1602 and a second rubber ring 1603 are respectively provided at the top and bottom of the placement plate 16 along the edge of the movable hole 1601. When the placement plate 16 moves in the length direction of the anchor rod 1701, the first limiting ring 1703 abuts against the first rubber ring 1602, or the second limiting ring 1704 abuts against the second rubber ring 1603. In order to avoid excessive impact between the two limiting rings and the placement plate 16 when the placement plate 16 moves a large range on the drawer plate 1501, thereby affecting the electromagnetic pulse instrument body 18, the impact can be reduced by the rubber rings.

[0028] In this embodiment, a number of reinforcing ribs are provided between the elastic clamping plate 1604 and the placement plate 16. Since the elastic clamping plate 1604 mainly uses its top semi-circular area as the clamping part, when it clamps the electromagnetic pulse instrument body 18, the radial force received by the top of the elastic clamping plate 1604 increases, making it easy to bend and deform. Therefore, a number of reinforcing ribs are provided to increase its stability.

[0029] In this embodiment, the drawer assembly 15 includes an exhaust fan 1402 disposed on the top of the protective box 10. The top of the protective box 10 has a heat dissipation hole 1401 in the direction of the exhaust fan 1402 outlet. Since the bottom of the protective box 10 is open, the air inlet is the gap around the drawer assembly 15, and then flows to the heat dissipation hole 1401 at the top to form a circulating heat dissipation channel.

[0030] As a preferred embodiment, the bottom of the protective box 10 is provided with a dustproof net to prevent dust from being sucked in when the bottom is used as an air inlet.

[0031] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
