Description

Technical Field

[0001] This utility model relates to the field of filters, and in particular to a filter that is easy to assemble and disassemble. Background Technology

[0002] The primary function of a filter is to remove interference waves from a circuit, ensuring that signals can be transmitted clearly and unobstructed to subsequent equipment. Typically, filters are fixed in place with bolts, and only need to be disassembled and replaced when the filter malfunctions or is damaged. During installation, multiple bolts are often symmetrically distributed to ensure the filter's stability. However, this installation method is particularly cumbersome during disassembly, requiring the loosening of multiple bolts one by one, which is both time-consuming and labor-intensive. More seriously, during repeated disassembly and reassembly, the rotation of the bolts can easily cause stripping of the mounting holes, preventing the bolts from being properly screwed in and secured, ultimately resulting in the filter not being securely installed in its intended position. In such cases, re-fixing the filter often necessitates remedial measures such as re-drilling holes. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defects of the existing technology. This utility model proposes a filter that is easy to assemble and disassemble.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A filter that is easy to assemble and disassemble includes: two U-shaped blocks and a filter. A first block is symmetrically mounted on each U-shaped block, and a second block that mates with the interior of each U-shaped block is symmetrically mounted on the filter. A first through hole is formed on the second block. The filter also includes a second through hole formed on the U-shaped blocks. A limiting rod is installed inside the second through hole. A connecting plate for synchronously moving all limiting rods is mounted on the limiting rod. The filter also includes a first elastic component installed between the connecting plate and the U-shaped blocks. By pulling the limiting rod through the connecting plate, the limiting rod is disengaged from the interior of the U-shaped blocks. At this time, the first elastic component deforms. Then, the second block is inserted into the interior of the U-shaped blocks, aligning the first and second through holes. The connecting plate is then released, and the first elastic component resets, driving the limiting rod to pass through the first and second through holes, thus fixing the filter.

[0005] Preferably, at least two first perforations are provided on each of the second blocks.

[0006] Preferably, the number and specifications of the first perforation and the second perforation are the same, and the spacing between the first perforation and the spacing between the second perforation are the same.

[0007] Preferably, the connecting plate is I-shaped, and the limiting rod is moved by moving the connecting plate.

[0008] Preferably, the first elastic component is a spring, and the spring is sleeved on the outside of the limiting rod.

[0009] Preferably, it also includes a fixing mechanism installed inside the second block for fixing the filter to the grid plate.

[0010] Preferably, the fixing mechanism includes a cavity formed within the second block, a slider that slides along the inside of the cavity is installed inside the cavity; a second elastic component is installed between the slider and the inner wall of the cavity; a rope is wound and fixed on the slider, the rope being used to pull the slider to move along the inside of the cavity; it also includes a groove formed on the second block, and a fixing rod is welded and fixed inside the groove. When the rope is pulled, the second elastic component deforms, and the slider slides along the inside of the cavity until it is in close contact with the inner wall of the cavity, at which point the rope is pulled out.

[0011] Preferably, the second elastic component is an elastic rope.

[0012] Preferably, one end of the rope extends movably to the outside of the second block, and the end of the rope located on the outside of the second block has a knot to prevent the rope from moving into the cavity.

[0013] Compared with the prior art, the beneficial effects of this utility model include: 1. First, install the U-shaped block at the destination position using bolts. Then, slide the filter into the U-shaped block using the second block. Next, fix the filter by passing the limiting rod through the first and second through holes. When disassembling, only the limiting rod needs to be moved. Subsequent installation and disassembly processes do not require disassembling and reassembling the U-shaped block. Only the filter needs to be disassembled and assembled. The operation is simple and convenient. Furthermore, the filter itself does not need to be installed with bolts, avoiding the problem of stripped threads.

[0014] 2. Simultaneously, the rope is stored inside the cavity. When the filter is installed at the mesh plate, the rope can be pulled out for installation. After disassembly, the rope is automatically stored inside the cavity and can be reused. Attached Figure Description

[0016] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0017] According to one embodiment of the present invention, in conjunction with Figures 1-4 As shown.

[0018] A filter designed for easy assembly and disassembly comprises two symmetrical U-shaped blocks 1 and a filter 2. Specifically, each U-shaped block 1 has a first block 3 symmetrically welded on it, with a bolt mounting hole in its center for secure fixing to a predetermined mounting point. The filter 2 has symmetrically arranged second blocks 4 matching the internal structure of the U-shaped blocks 1, each second block 4 having at least two first through holes 5 to ensure a secure connection. Simultaneously, the U-shaped blocks 1 also have corresponding second through holes 6 with the same number, size, and spacing as the first through holes 5.

[0019] To facilitate rapid assembly and disassembly, the device is equipped with limiting rods 8, which are movably inserted into the second through holes 6. Specifically, an I-shaped connecting plate 14 is designed and welded to all the limiting rods 8. Moving the connecting plate 14 synchronously moves all the limiting rods 8. Furthermore, a first elastic component 7 is welded between the connecting plate 14 and the U-shaped block 1. This component can be an arc-shaped elastic sheet, but more preferably a spring, with the spring sleeved on the outside of the limiting rods 8. When the filter 2 needs to be installed, simply pull the limiting rods 8 through the connecting plate 14 to disengage them from the inside of the U-shaped block 1 (at which point the first elastic component 7 deforms), and then insert the second block 4 into the U-shaped block 1, ensuring that the first through hole 5 aligns with the second through hole 6. After releasing the connecting plate 14, the first elastic component 7 resets, driving the limiting rods 8 through the first through hole 5 and the second through hole 6, thereby firmly fixing the filter 2.

[0020] Furthermore, this embodiment also includes a fixing mechanism for securely mounting the filter 2 onto the grid plate. This fixing mechanism includes a cavity 9 formed inside the second block 4, within which a slidable slider 12 is installed. A second elastic component 11, which can be a spring but is more preferably an elastic rope, is welded between the slider 12 and the inner wall of the cavity 9. A rope 13 is wound around the slider 12, with one end extending movably to the outside of the second block 4 and secured with a knot to prevent it from completely retracting into the cavity 9. Simultaneously, a groove is formed on the second block 4, within which a fixing rod 10 is welded. In use, simply pulling the rope 13 deforms the second elastic component 11, causing the slider 12 to slide along the cavity 9 and adhere tightly to the inner wall. Then, pulling the rope 13 out through the gaps in the grid plate, and then back through and securing it to the fixing rod 10, easily achieves a secure fixation of the filter 2 on the grid plate.

[0021] Working principle: When filter 2 needs to be installed inside the cabinet, U-shaped block 1 is fixed inside the cabinet by bolts through the holes on the first block 3. Then, the limiting rod 8 is pulled by the connecting plate 14, so that the first elastic component 7 is stretched and deformed. Then, filter 2 is moved downward from the top of U-shaped block 1, so that the second block 4 passes through the inside of U-shaped block 1 until the first through hole 5 and the second through hole 6 are aligned. Then the connecting plate 14 is released, and the first elastic component 7 is reset. The limiting rod 8 is driven to pass through the aligned first through hole 5 and second through hole 6, so that filter 2 is fixed on U-shaped block 1. At this time, the fixing of filter 2 is completed. Alternatively, filter 2 can be moved upward from the bottom of U-shaped block 1, so that the second block 4 passes through the inside of U-shaped block 1. When disassembling filter 2, the limiting rod 8 is moved again through the connecting plate 14. At this time, the limiting rod 8 is disengaged from the first through hole 5 and the second through hole 6, so filter 2 can be moved up or down to disassemble filter 2. When the filter 2 is mounted on the grid plate, the rope 13 is pulled out from inside the cavity 9 through the knot on the rope 13. The slider 12 moves along the inside of the cavity 9 until the slider 12 is in close contact with the inner wall of the cavity 9. At this time, the second elastic component 11 is in a deformed state. Then the pulled-out rope 13 is passed through the hole in the grid plate, and then back through the hole. Finally, it is wrapped and fixed to the fixing rod 10, completing the fixation of the filter 2 on the grid plate. When disassembling, the second elastic component 11 is reset, and the rope 13 is pulled back and stored inside the cavity 9 for easy storage and subsequent reuse.

[0022] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
