[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0030] Example 1:

[0031] Reference Figures 1-5 This is the first embodiment of the present utility model. This embodiment provides an anti-interference device for electronic information equipment, including a mounting frame 1. An anti-interference device body 2 is installed inside the mounting frame 1. Two sets of snap-fit ​​components 3 with a left-right symmetrical design are arranged inside the mounting frame 1.

[0032] Mounting frame 1 serves as the external support frame for the entire anti-interference device, providing installation space for the anti-interference device body 2 and other internal components, protecting the internal components, and facilitating the installation of the entire anti-interference device on other equipment or locations. The anti-interference device body 2 is the core functional part of the entire anti-interference device, suppressing and processing interference from electronic information equipment through its internal components. It should be noted that the model of the anti-interference device body 2 is DL15-PCLK-B1105. The snap-fit ​​component 3 facilitates the installation and separation of the anti-interference device body 2 from the mounting frame 1, thereby facilitating the maintenance of the device.

[0033] An installation plate 4 is fixed inside the anti-interference device body 2. Multiple sets of connector bodies 5 are installed on one side of the installation plate 4. A fixing frame 6 and a back plate 7 are installed on the inner wall of the anti-interference device body 2 respectively. A protective component 8 is provided on one side of the back plate 7.

[0034] The mounting plate 4 is set to provide a stable installation position for the connector body 5. The connector body 5 is set to connect to the external electronic information equipment circuit, realize the signal transmission between the anti-interference device and the external equipment, and is an important interface for the anti-interference device to interact with the external equipment. The fixed frame 6 and the back plate 7 work together to form a relatively independent space inside the anti-interference device body 2, which is used to install and protect the protective component 8, and also provides a certain support and fixation for the connector body 5.

[0035] The snap-fit ​​assembly 3 includes a spring 31 fixed to the inner wall of the mounting frame 1. One end of the spring 31 is fixed with a plug block 32. The bottom of the anti-interference device body 2 is fixed with a plug tube 33. The outer side of the plug block 32 is plugged into the inner wall of the plug tube 33. A pull rod 34 is fixed to one side of the plug block 32. The outer side of the pull rod 34 is slidably connected to the inner wall of the mounting frame 1.

[0036] The spring 31 is designed to provide elasticity to the plug block 32, enabling the plug block 32 to remain inserted into the plug tube 33. By inserting into the plug tube 33, the plug block 32 can fix the position of the anti-interference device body 2 within the mounting frame 1, ensuring that the anti-interference device body 2 will not shake or fall off. The plug tube 33 is designed to provide an insertion channel for the plug block 32. The pull rod 34 is designed to facilitate manual pulling by the operator. By pulling the pull rod 34, the plug block 32 can be driven to compress the spring 31 and disengage from the plug tube 33, thereby separating the anti-interference device body 2 from the mounting frame 1, which facilitates the installation, disassembly and maintenance of the equipment. It should be noted that the spring 31 can be selected with a wire diameter of 1-2mm, an outer diameter of 10-15mm, a free length of 20-30mm, and moderate elasticity to stably insert the anti-interference device body 2.

[0037] Example 2:

[0038] This is the second embodiment of the present invention, which is based on the previous embodiment.

[0039] Specifically, four sets of L-shaped plates 9 are installed on the outer side of the mounting frame 1 by screws, and two sets of mounting holes 10 are opened on the inner wall of each of the four sets of L-shaped plates 9.

[0040] The four sets of L-shaped plates 9 provide multiple mounting points, enabling the mounting frame 1 to be stably fixed to external equipment or structures. The mounting holes 10 are used to connect the mounting frame 1 to the external equipment or structures with screws, thereby achieving the installation and fixation of the mounting frame 1.

[0041] Specifically, four sets of cross-shaped inserts 11 are fixed to the inner wall of the mounting frame 1, and four sets of fixing blocks 12 are fixed to the bottom of the anti-interference device body 2, with the outer side of the cross-shaped inserts 11 being inserted into the inner wall of the fixing blocks 12.

[0042] By using the cross-shaped insert 11 in conjunction with the fixing block 12 at the bottom of the anti-interference device body 2, the stability of the anti-interference device body 2 within the mounting frame 1 can be further enhanced, preventing it from shaking or shifting.

[0043] Specifically, the bottom of the mounting frame 1 has multiple sets of heat dissipation vents 13, and the inner wall of the heat dissipation vents 13 is fixed with a filter screen 14.

[0044] The heat dissipation vent 13 is designed to dissipate the heat generated by the anti-interference device body 2 during operation, preventing performance degradation or damage due to overheating. The filter screen 14 is designed to prevent dust and debris from entering the mounting frame 1, avoiding dust accumulation that affects the heat dissipation and performance of the device, while ensuring smooth airflow for heat dissipation.

[0045] Specifically, a mounting bracket 15 is fixed to one side of the mounting plate 4, and a mounting seat 16 for mounting the connector body 5 is provided on one side of the mounting bracket 15.

[0046] The mounting bracket 15 is provided to support the mounting base 16, so that the mounting base 16 can be stably installed inside the anti-interference device body 2. The mounting base 16 is used to install the connector body 5, ensuring that the connector body 5 is firmly installed.

[0047] Example 3:

[0048] This is the third embodiment of the present invention, which is based on the first two embodiments.

[0049] Specifically, multiple sets of positioning rods 17 are fixed on one side of the fixed frame 6, and multiple sets of positioning holes 18 are opened on the inner wall of the back plate 7, with the outer side of the positioning rods 17 being inserted into the inner wall of the positioning holes 18.

[0050] By inserting the positioning rod 17 into the positioning hole 18 on the inner wall of the back plate 7, the installation position of the back plate 7 on the fixed frame 6 can be determined, thereby realizing the positioning and installation of the back plate 7.

[0051] Specifically, a first knob 19 is rotatably connected to one side of the fixed frame 6, and a first limiting groove 20 is provided on the inner wall of the back plate 7 for limiting the first knob 19, and the first limiting groove 20 is designed horizontally.

[0052] The first knob 19 can be rotated 90 degrees to form a cross lock with the first limiting groove 20, thereby limiting the back plate 7 in the lateral direction and preventing the back plate 7 from moving laterally.

[0053] Specifically, two sets of second knobs 21 with a symmetrical design are rotatably connected to one side of the fixed frame 6, and two sets of second limiting grooves 22 are provided on the inner wall of the back plate 7 for limiting the second knobs 21, and the second limiting grooves 22 are designed vertically.

[0054] The second knob 21 can be rotated 90 degrees to form a cross lock with the second limiting groove 22, thereby limiting the back plate 7 in the vertical direction and preventing the back plate 7 from moving vertically.

[0055] Specifically, the protective component 8 includes a limiting frame 81 fixed to one side of the back plate 7. The inner wall of the limiting frame 81 is provided with a wire hole 82. The inner wall of the limiting frame 81 is provided with multiple sets of slide rails 83. The inner wall of the slide rails 83 is slidably connected to a protective plate 84, and a handle is fixed to the top of the protective plate 84.

[0056] The limiting frame 81 provides installation and sliding space for the protective plate 84, and also limits the wire hole 82. The wire hole 82 is designed for the wire to pass through, facilitating the organization and protection of the wire. The slide rail 83 is designed to provide a sliding track for the protective plate 84, allowing the protective plate 84 to slide smoothly and enabling the opening and closing of the wire hole 82. By sliding the protective plate 84, the wire hole 82 can be opened or closed. When not in use, the wire hole 82 is closed to prevent dust and debris from entering and to protect the internal wiring and connector body 5. When wiring needs to be connected, the protective plate 84 is opened to facilitate the wire insertion.

[0057] Specifically, the inner wall of the back plate 7 is provided with multiple sets of through holes 23 for placing the connector body 5, and the positions of the through holes 23 correspond to the positions of the wire holes 82. A rubber ring 24 is fixed to the inner wall of the through holes 23.

[0058] The through hole 23 is provided for the wires of the connector body 5 to pass through, so that the external wires can be connected to the connector body 5. The rubber ring 24 can protect and fix the wires that pass through, prevent wire wear, and increase the sealing between the wires and the through hole 23.

[0059] Working principle: During the installation phase, the mounting frame 1 is first securely installed on the external equipment or structure using screws through the mounting holes 10 on the four sets of L-shaped plates 9. Next, the pull rod 34 is pulled outward, causing the plug-in block 32 to compress the spring 31. Then, the anti-interference device body 2 is placed into the mounting frame 1, and the pull rod 34 is released. At this time, the cross-shaped plug 11 on the inner wall of the mounting frame 1 is inserted into the fixing block 12 at the bottom of the anti-interference device body 2. Simultaneously, the elastic force of the spring 31 causes the plug-in block 32 to insert into the plug-in cylinder 33 at the bottom of the anti-interference device body 2, initially fixing the anti-interference device body 2. Subsequently, the position of the back plate 7 on the fixing frame 6 is determined by the insertion of the positioning rod 17 into the positioning hole 18 on the inner wall of the back plate 7. At this time, the first knob 19 and the second knob 21 are in the state of passing through the first limiting groove 20 and the second limiting groove 22. Then, the first knob 19 is rotated 90 degrees, so that the first knob 19 and the first limiting groove 20 form a cross locking state. Simultaneously, rotate the two sets of second knobs 21 ninety degrees to make the second knobs 21 and the second limit groove 22 cross-lock, completing the installation and fixation of the back plate 7. During use, the anti-interference device body 2 suppresses and processes the interference of electronic information equipment through internal components. The external equipment line is connected to the connector body 5 fixed on the mounting base 16 on the mounting plate 4 through the through hole 23 on the back plate 7 to realize signal transmission. At the same time, the rubber ring 24 in the through hole 23 protects the line. During maintenance, simply pull the pull rod 34 to drive the plug block 32 to compress the spring 31 and disengage from the plug cylinder 33, and the anti-interference device body 2 can be easily separated from the mounting frame 1. If the connector body 5 needs to be operated, slide the protective plate 84 to open the wire hole 82. In addition, the heat dissipation vent 13 can dissipate the heat generated by the anti-interference device body 2 during operation in a timely manner, and the filter screen 14 prevents dust and debris from entering, ensuring stable operation of the equipment.

[0060] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
