Description

Technical Field

[0001] This utility model relates to the field of anti-interference device technology, and in particular to an electronic information anti-interference device. Background Technology

[0002] Driven by the rapid development of the information age, wireless communication technology has quickly risen to become an indispensable key infrastructure in modern society due to its significant advantages such as flexibility, convenience, and lack of complex wiring. However, with the widespread application of wireless communication technology in various fields, the increasingly serious problem of interference has also emerged. Wireless communication mainly relies on electromagnetic wave signals to propagate in free space to achieve information exchange, but this propagation process is extremely susceptible to interference from various factors, which in turn affects the stability and quality of communication. In order to effectively address this challenge and ensure that communication always maintains a high quality level, equipping ourselves with professional anti-interference equipment has become an inevitable choice.

[0003] To simplify the manufacturing process, most mainstream electronic information anti-jamming devices on the market use a non-removable structure for their antennas, which are fixedly connected to the main body of the anti-jamming device. This design means that when the antenna is damaged, the main body of the anti-jamming device must be completely disassembled for replacement, which is not only cumbersome but also increases maintenance costs and time consumption. Summary of the Invention

[0004] This utility model relates to an electronic information anti-interference device, which solves the problem that existing electronic information anti-interference devices, in order to simplify the manufacturing process, generally use a non-detachable structure for their matching antennas, which are fixedly connected to the anti-interference device body. This design results in the anti-interference device body having to be completely disassembled to replace the antenna when it is damaged, which is a cumbersome operation.

[0005] In a first aspect, this utility model provides an electronic information anti-interference device, specifically comprising: an anti-interference device, an antenna, an upper sleeve, a lower sleeve, and a nut; the anti-interference device includes a connector on its exterior, with the antenna connected to the top of the connector; the upper sleeve and the lower sleeve are installed on the exterior of the connector, with the upper sleeve located on top of the lower sleeve and the bottom of the upper sleeve contacting the top of the lower sleeve; a nut is connected to the exterior of the connector, with the nut located at the bottom of the lower sleeve.

[0006] Furthermore, the bottom end of the antenna is inserted into the top of the connector, and the internal wiring of the antenna is inserted together with the internal wiring of the connector. The antenna is connected to the anti-interference device through the insertion method, and the antenna is connected to the wireless communication device through the anti-interference device.

[0007] Furthermore, the top of the connector is symmetrically provided with slots, and the bottom of the antenna is symmetrically provided with connecting blocks. The connecting blocks are slidably connected in the slots, and the connecting blocks and slots slide together to guide the antenna.

[0008] Furthermore, the upper sleeve is rotatably connected to the connector, and an L-shaped groove is provided around the top of the upper sleeve. The L-shaped groove is connected to the slot, and the end of the connecting block is located in the L-shaped groove. When the connecting block is located at the innermost end of the L-shaped groove, the connecting block is at the bend of the L-shaped groove. Rotating the upper sleeve moves the connecting block to the innermost end of the L-shaped groove, thereby fixing the connecting block.

[0009] Furthermore, the lower sleeve is slidably connected to the connector, and the connector is symmetrically provided with sliders on the outside, and the lower sleeve is symmetrically provided with sliding holes inside, with the sliders slidably connected to the sliding holes.

[0010] Furthermore, the upper sleeve has symmetrically arranged positioning grooves at its bottom, and the lower sleeve has symmetrically arranged positioning blocks at its top, with the positioning blocks inserted into the positioning grooves.

[0011] Furthermore, the connector is provided with an external thread, and the nut is threaded to the outside of the connector. The top of the nut contacts the bottom of the lower sleeve. When the connecting block moves to the innermost end of the L-shaped groove, the positioning groove moves to the top of the positioning block. When the nut is rotated, the nut drives the lower sleeve to move upward, so that the positioning block is inserted into the positioning groove. The lower sleeve fixes the upper sleeve.

[0012] This utility model provides an electronic information anti-interference device, which has the following beneficial effects:

[0013] In use, this invention employs a plug-in design to securely connect the antenna and the anti-interference device. The antenna establishes a communication link with the wireless communication device via the anti-interference device, effectively ensuring excellent anti-interference performance of the communication signal. In this structure, the connecting block and the slot use a sliding engagement mechanism to provide precise guidance during antenna installation. When the connecting block slides to the innermost end of the L-shaped slot and is precisely at the bend of the L-shaped slot, rotating the upper sleeve further secures the connecting block to the innermost end of the L-shaped slot, thus fixing the connecting block in place and effectively ensuring the tightness and firmness of the connection between the antenna and the connector.

[0014] Furthermore, when the connecting block is moved to the innermost end of the L-shaped groove, the positioning groove is exactly above the positioning block. Turning the nut will cause the lower sleeve to move upward, thus allowing the positioning block to be precisely inserted into the positioning groove. The lower sleeve securely fixes the upper sleeve, ensuring reliable fixation of the antenna. If the antenna is damaged and needs to be replaced, simply turn the nut in the opposite direction. The lower sleeve will move downward under gravity, and the positioning block will separate from the positioning groove, releasing the fixation of the upper sleeve. Turn the upper sleeve in the opposite direction to move the connecting block to the bend of the L-shaped groove. At this point, the antenna can be pulled upward to easily separate it from the connector. Then, a new antenna can be installed. The entire operation is simple, convenient, efficient, and time-saving.

[0025] 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, not all, of the embodiments of this utility model. Based on the described 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.

[0026] Example 1: Please refer to Figures 1 to 4 :

[0027] This utility model proposes an electronic information anti-interference device, including: an anti-interference device 1, an antenna 2, an upper sleeve 3, a lower sleeve 4, and a nut 5; the anti-interference device 1 includes a connector 11 on the outside, with the antenna 2 connected to the top of the connector 11; the upper sleeve 3 and the lower sleeve 4 are installed on the outside of the connector 11, with the upper sleeve 3 located on top of the lower sleeve 4 and the bottom of the upper sleeve 3 in contact with the top of the lower sleeve 4; the nut 5 is connected to the outside of the connector 11 and is located at the bottom of the lower sleeve 4; the bottom end of the antenna 2 is inserted into the top of the connector 11, and the internal wiring of the antenna 2 is connected to the internal wiring of the connector 11. The antenna 2 is connected to the anti-interference device 1 through the insertion method, and the antenna 2 is connected to the wireless communication device through the anti-interference device 1, effectively ensuring the anti-interference effect of the communication signal; slots 111 are symmetrically arranged on the top of the connector 11, and connecting blocks 21 are symmetrically arranged on the bottom of the antenna 2. The connecting blocks 21 are slidably connected in the slots 111, and the sliding cooperation between the connecting blocks 21 and the slots 111 plays a guiding role for the antenna 2.

[0028] In this embodiment of the utility model, the upper sleeve 3 is rotatably connected to the connector 11, and an L-shaped groove 31 is provided around the top of the upper sleeve 3. The L-shaped groove 31 is connected to the slot 111, and the end of the connecting block 21 is located in the L-shaped groove 31.

[0029] Using the above technical solution, when the connecting block 21 is located at the innermost end of the L-shaped groove 31, the connecting block 21 is at the bend of the L-shaped groove 31. Rotating the upper sleeve 3 moves the connecting block 21 to the innermost end of the L-shaped groove 31, which has the effect of fixing the connecting block 21 and ensuring the firmness of the connection between the antenna 2 and the connector 11.

[0030] In Example 2, based on Example 1, the lower sleeve 4 is slidably connected to the connector 11. The connector 11 is symmetrically provided with sliders 112 on the outside, and the lower sleeve 4 is symmetrically provided with sliding holes 41 inside. The sliders 112 are slidably connected in the sliding holes 41. The bottom of the upper sleeve 3 is symmetrically provided with positioning grooves 32, and the top of the lower sleeve 4 is symmetrically provided with positioning blocks 42. The positioning blocks 42 are inserted into the positioning grooves 32. The connector 11 is provided with external threads, and the nut 5 is threadedly connected to the outside of the connector 11. The top of the nut 5 contacts the bottom of the lower sleeve 4.

[0031] Using the above technical solution, when the connecting block 21 moves to the innermost end of the L-shaped groove 31, the positioning groove 32 moves directly above the positioning block 42. Rotating the nut 5 causes the lower sleeve 4 to move upward, allowing the positioning block 42 to be inserted into the positioning groove 32. The lower sleeve 4 then fixes the upper sleeve 3, ensuring the upper sleeve 3's effective fixation of the antenna 2. When the antenna 2 is damaged and needs to be replaced, rotating the nut 5 in the opposite direction causes the lower sleeve 4 to move downward under gravity, separating the positioning block 42 from the positioning groove 32. The upper sleeve 3 is then released from its fixation, and the upper sleeve 3 can be rotated in the opposite direction to move the connecting block 21 to the bend of the L-shaped groove 31. This allows the antenna 2 to be pulled upward, separating it from the connector 11 and replacing it with a new antenna 2. The operation is simple and quick.

[0032] The working principle of this embodiment is as follows: First, the antenna 2 is connected to the anti-interference device 1 via a plug-in connection. The internal wiring of the antenna 2 is plugged into the internal wiring of the connector 11. The antenna 2 is connected to the wireless communication device through the anti-interference device 1, effectively ensuring the anti-interference effect of the communication signal. When the connecting block 21 is located at the innermost end of the L-shaped groove 31, the connecting block 21 is at the bend of the L-shaped groove 31. Rotating the upper sleeve 3 moves the connecting block 21 to the innermost end of the L-shaped groove 31, which fixes the connecting block 21 and ensures the firmness of the connection between the antenna 2 and the connector 11. When the connecting block 21 moves to the innermost end of the L-shaped groove 31, the positioning groove 32... Move the device to the top of the positioning block 42, rotate the nut 5, and the nut 5 will move the lower sleeve 4 upward, so that the positioning block 42 is inserted into the positioning groove 32. The lower sleeve 4 fixes the upper sleeve 3, thus ensuring the upper sleeve 3 fixes the antenna 2. When the antenna 2 is damaged and needs to be replaced, rotate the nut 5 in the opposite direction. The lower sleeve 4 will move downward under the influence of gravity, so that the positioning block 42 is separated from the positioning groove 32. The upper sleeve 3 is released from fixation. The upper sleeve 3 can be rotated in the opposite direction to move the connecting block 21 to the bend of the L-shaped groove 31. Then, the antenna 2 can be pulled upward to separate the antenna 2 from the connector 11 and replace it with a new antenna 2. The operation is simple and quick.
