Abstract
Description
Technical Field
[0001] This utility model relates to the field of electromagnetic signal protection technology, and more specifically, to an electromagnetic signal protection instrument. Background Technology
[0002] The main functions of electromagnetic signal protection instruments include preventing electromagnetic interference, protecting electronic equipment, ensuring information security, and improving equipment performance. Specifically, these instruments effectively control electromagnetic signals within a specific area through techniques such as physical shielding, filtering, absorption, or interference cancellation. They can prevent strong external electromagnetic interference from intruding and protect internal electronic equipment from damage.
[0003] Existing electromagnetic signal protection instruments use a direct plug-in interface. If the cable is accidentally pulled during use, the plug may be pulled off or become loose, causing the device to lose power and fail to provide normal protection. This allows other signal devices to take advantage of the situation. In addition, the existing electromagnetic signal protection instruments have exposed and open interfaces, which makes it easy for dust to enter the interfaces when not in use, leading to poor contact during later use and reducing the effectiveness of electromagnetic signal protection. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] In view of the shortcomings of the existing technology, this utility model provides an electromagnetic signal protection instrument with advantages such as dustproof and pull-proof, which solves the problem that the existing device is prone to loose plugs or dust entering the interface, resulting in poor plug contact.
[0006] (II) Technical Solution
[0007] To achieve the aforementioned dustproof and tear-proof objectives, this utility model provides the following technical solution: an electromagnetic signal protection instrument, comprising an electromagnetic protection instrument and multiple sockets disposed on one side of the electromagnetic protection instrument. Each socket is provided with a fixing component and a plug. Two fixing blocks are disposed on the front of the fixing component, symmetrically distributed left and right. A movable rod is disposed within each fixing block. Two movable blocks are disposed outside the movable rod, symmetrically distributed vertically. A baffle is fixedly disposed on one side of each of the two movable blocks. A locking block is disposed on one side of the baffle. Two torsion springs symmetrically distributed vertically are sleeved on the outside of the movable rod. A locking groove is provided on the outside of the plug.
[0008] In an embodiment of this utility model, a fixed base is fixedly provided at the corner of the electromagnetic protection instrument, and an antenna is provided on the fixed base.
[0009] In an embodiment of this utility model, the top of the fixing base is provided with a storage slot, the antenna is a telescopic design, and the diameter of the storage slot is larger than the diameter of the antenna.
[0010] In an embodiment of this utility model, a fixing groove is provided inside the fixing block, and the movable rod is disposed in the fixing groove and rotatably connected to the fixing groove.
[0011] In an embodiment of this utility model, the two ends of the torsion spring abut against the movable block and the fixed groove respectively, and the fixed block has two arc-shaped openings.
[0012] In an embodiment of this utility model, a handle is provided on one side of the baffle, and the locking block is made of rubber.
[0013] In an embodiment of this utility model, the plug is inserted into the socket, and a wiring cable is fixedly provided at the other end of the plug.
[0014] In an embodiment of this utility model, the card block is inserted into the card slot and fits tightly against the card slot.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] This utility model is equipped with a baffle. When not in use, the elastic potential energy of the torsion spring causes the baffle to cover the front of the socket, which can prevent dust from entering the socket and causing poor contact between the plug and the socket during later use, thus affecting the protection effect of electromagnetic signals. In addition, when the plug is inserted into the socket, the torsion spring also causes the locking block to insert into the locking slot to limit the plug and prevent the plug from being pulled out of the socket or loosened in case of accidental pulling of the wiring cable.

Detailed Implementation
[0024] 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.
[0025] 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.
[0026] Please see Figure 1-4This utility model provides a technical solution: an electromagnetic signal protection instrument, including an electromagnetic protection instrument 10 and multiple sockets 20 disposed on one side of the electromagnetic protection instrument 10. Each socket 20 is provided with a fixing member 30 and a plug 31. Two fixing blocks 3001 are disposed on the front of the fixing member 30, symmetrically distributed from left to right. A movable rod 3003 is disposed inside each fixing block 3001. Two movable blocks 3004 are disposed outside the movable rod 3003, symmetrically distributed vertically. A baffle 3005 is fixedly disposed on one side of each movable block 3004. A locking block 3006 is disposed on one side of the baffle 3005. Two torsion springs 3008 symmetrically distributed vertically are sleeved on the outside of the movable rod 3003. A slot 3101 is opened on the outside of the plug 31.
[0027] In this embodiment, a fixed base 40 is fixedly installed at the corner of the electromagnetic protection instrument 10. An antenna 4002 is installed on the fixed base 40. The main function of the antenna 4002 is to receive and transmit electromagnetic waves, convert electrical signals into electromagnetic waves with specific frequency, amplitude and other characteristics. These electromagnetic waves are used to transmit information. The antenna 4002 can also convert specific electromagnetic waves into electrical signals for receiving information.
[0028] The top of the mounting base 40 is provided with a storage slot 4001. The antenna 4002 is telescopic. The diameter of the storage slot 4001 is larger than the diameter of the antenna 4002. When not in use or during transportation, the antenna 4002 can be retracted into the storage slot 4001 for storage.
[0029] In this embodiment, a fixing groove 3002 is provided inside the fixing block 3001, and the movable rod 3003 is disposed in the fixing groove 3002 and rotatably connected to the fixing groove 3002.
[0030] It should be noted that the two ends of the torsion spring 3008 abut against the movable block 3004 and the fixed groove 3002 respectively. The fixed block 3001 has two arc-shaped openings 3009. When the device is not in use, the baffle 3005 is in contact with the front of the socket 20 under the action of the torsion spring 3008, which can prevent dust from entering the interior of the socket 20, which would cause the plug 31 to not disengage properly from the socket 20 when it is used again, thus reducing the protective effect of the electromagnetic protection instrument 10.
[0031] Understandably, a handle 3007 is provided on one side of the baffle 3005 to facilitate pulling the baffle 3005 to rotate. For example, when it is necessary to insert the plug 31 into the socket 20, the baffle 3005 is rotated to ninety degrees by pulling the handle 3007, and then the plug 31 is inserted into the socket 20. Then the handle 3007 is released. At this time, the baffle 3005 moves towards the side closer to the plug 31 under the elastic potential energy of the torsion spring 3008. The locking block 3006 is made of rubber, so that the locking block 3006 can undergo a certain degree of deformation.
[0032] In this embodiment, the plug 31 is connected to the socket 20, and the other end of the plug 31 is fixedly provided with a wiring cable 3102.
[0033] It should be emphasized that when the locking block 3006 is inserted into the slot 3101 and fits tightly against the slot 3101, when the baffle 3005 moves towards the side closer to the plug 31 under the elastic potential energy of the torsion spring 3008, the locking block 3006 is inserted into the slot 3101 during this process. At this time, the locking block 3006 plays a limiting role for the plug 31, preventing the plug 31 from being pulled out of the socket 20 when the wiring cable 3102 is pulled.
[0034] Specifically, the working principle of this electromagnetic signal protection instrument is as follows:
[0035] When using this device, first pull the antenna 4002 out of the storage slot 4001, then pull the baffle 3005 to rotate it ninety degrees using the handle 3007, then insert the plug 31 into the socket 20, and then release the handle 3007. At this time, the baffle 3005 moves towards the side closer to the plug 31 under the elastic potential energy of the torsion spring 3008. During this process, the locking block 3006 is inserted into the locking slot 3101, at which time the locking block 3006 limits the plug 31. To prevent the plug 31 from being pulled out of the socket 20 when the wiring cable 3102 is being pulled, when the device is not in use, the baffle 3005 is in contact with the front of the socket 20 under the action of the torsion spring 3008, which can prevent dust from entering the interior of the socket 20, which would cause the plug 31 to not disengage properly from the socket 20 when it is used again, thus reducing the protective effect of the electromagnetic protection instrument 10. Finally, the antenna 4002 is compressed into the storage slot 4001 to prevent the antenna 4002 from being broken when not in use.
[0036] It should be noted that the specific models and specifications of the electromagnetic protection instrument 10, socket 20, card block 3006, torsion spring 3008, plug 31, wiring cable 3102, and antenna 4002 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.
[0037] In the description of this utility model, it should be understood that the terms "coaxial", "bottom", "one end", "top", "middle", "other end", "upper", "side", "top", "inner", "front", "center", "both ends", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0038] Furthermore, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first," "second," "third," or "fourth" may explicitly or implicitly include at least one of those features.
[0039] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "setting", "connection", "fixing", "screw connection", etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or the interaction between two components. Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0040] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
