Description

Technical Field

[0001] The utility model relates to the technical field of magnetic rings, in particular to a snap-fit ​​assembly type anti-demagnetization ring. Background Art

[0002] A magnetic ring is a ring-shaped magnetic conductor and is a commonly used anti-interference component in electronic circuits. It has a good inhibitory effect on high-frequency noise. To facilitate the winding of cables, an assembled magnetic ring can be used to first wind the cable around the magnetic ring and then clamp the magnetic ring, thereby improving the winding efficiency of the cable. Therefore, it is widely used. However, the existing assembled magnetic ring still has certain defects, such as:

[0003] The "snap-on magnetic ring" with application number CN202121938811.8 includes an upper magnetic ring and a lower magnetic ring. A through slot is provided inside the upper magnetic ring, a spring is fixed to one side of the through slot, a movable rod is fixed to one side of the spring, a movable plate is fixed to the outer surface of the movable rod, and a notch is provided on the outer surface of the upper magnetic ring. The utility model is provided with a spring, a movable rod, a movable plate, a notch, a slot and a rubber block. When the user needs to wind the wire, the user pulls the movable plate, which drives the movable rod to compress the rubber block to both sides and remove it from the slot, thereby opening the upper and lower magnetic rings. Conversely, if fixing is required, after the winding is completed, the movable plate is released, so that the movable rod is returned to its position by the spring, and one end of the movable rod passes through the rubber block, which is compressed so that the movable rod is snapped into the slot.

[0004] However, the above-mentioned magnetic ring is only provided with a snap-fit ​​structure on one side when in use, so it is difficult to ensure the stability of the connection on the other side, and the movable plate leaks out after assembly, which not only affects the appearance, but also easily causes accidental disassembly when hit by external force, causing it to fall off, and has limitations in use. In view of this, a snap-fit ​​assembly anti-demagnetization ring is proposed to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a snap-fit ​​assembly type anti-demagnetization ring to solve the problems of poor stability of the existing assembled magnetic ring connection installation and easy falling off proposed in the above background technology.

[0006] To achieve the above purpose, the present invention provides the following technical solutions: a snap-fit ​​assembly type anti-demagnetization ring, comprising a front magnetic ring and a rear magnetic ring,

[0007] A front engaging strip, the front engaging strip being fixedly mounted on the right rear end surface of the front magnetic ring;

[0018] The above technical solution facilitates assembly through the arrangement of the first clamping column and the first clamping slot.

[0019] As a preferred technical solution of the present utility model, the second engaging mechanism includes:

[0020] a slide plate, the slide plate being slidably connected to the rear wall surface of the cavity;

[0021] a second clamping column, the second clamping column being fixedly mounted on the left side of the slide plate and slidingly extending through the left side of the front engaging strip;

[0022] a second card slot, the second card slot being provided on the right side of the rear fitting strip, and the second card slot being aligned with the second card post;

[0023] A straight rod, the straight rod being fixedly mounted on the right side of the slide;

[0024] A first spring, wherein the left end of the first spring is fixedly connected to the right end surface of the straight rod, and the right end of the first spring is fixedly connected to the right wall surface of the cavity.

[0025] The adoption of the above technical solution facilitates assembly through the arrangement of the second clamping column and the second clamping groove, thereby improving the stability of assembly.

[0026] As a preferred technical solution of the present invention, the left end surface of the second clamping column is arranged as a backward inclined surface.

[0027] By adopting the above technical solution, when the rear engaging strip contacts the second clamping post, the second clamping post is pushed to move to the right.

[0028] As a preferred technical solution of the present utility model, the disassembly mechanism includes:

[0029] A movable plate, the movable plate being slidably connected to the rear wall of the cavity, the movable plate being located on the right side of the slide plate, and the straight rod being slidably arranged through the movable plate;

[0030] A twisted rod, the twisted rod is arranged through the movable plate, the twisted rod and the movable plate form a threaded connection structure, and the twisted rod slides through and is arranged in the groove;

[0032] The baffle is fixedly sleeved on the outer side of the straight rod, and the left side of the baffle abuts against the right side of the movable plate.

[0033] By adopting the above technical solution, it is easy to push the push block to the left to move the hemp rod to the left, so that the movable plate drives the baffle and the straight rod to move to the right, thereby causing the slide to drive the second clamping column to move out of the second clamping slot to the right, thereby realizing disassembly.

[0037] By adopting the above technical solution, the push block and the twisted rod can be reset and moved to the right by setting the second spring.

[0038] Compared with the prior art, the beneficial effects of the present invention are as follows: the snap-fit ​​assembly type anti-dropping magnetic ring can ensure a stable and effective snap-fit ​​connection, improve the stability of use, and at the same time, no accessories are leaked after snap-fit ​​assembly, ensuring the aesthetics while preventing accidental touch and drop-off, thereby improving the practicality of the magnetic ring;

[0039] 1. The first clamping column and the first clamping groove cooperate to ensure that the left end faces of the front magnetic ring and the rear magnetic ring are engaged and connected;

[0040] 2. At the same time, when the front and rear fitting strips are close to each other, the rear fitting strip contacts the second clamping column, pushing the second clamping column to the right, causing the slide to drive the straight rod to move synchronously and compress the first spring. When the second clamping slot is collinear with the second clamping column, the first spring releases the straight rod to drive the slide rod and the second clamping column to return to the left, causing the second clamping column to snap into the second clamping slot, achieving stable and effective clamping and assembly of the front and rear magnetic rings. After assembly, no accessories are leaked, thereby preventing them from falling off due to contact.

[0041] 3. During disassembly, the push block is pushed to the left by using a tool to compress the second spring, so that the twist rod moves to the left, thereby causing the movable plate to drive the straight rod, the slide plate and the second clamping column to move to the right through the baffle. Disassembly is achieved after the second clamping column moves out of the second clamping slot. After disassembly, the push on the push block is released. Under the release action of the second spring, the push block drives the twist rod to return to the right, so that the movable plate returns to the left until it contacts the limit block. The limit block limits the movable plate, thereby ensuring that the push block is placed in the groove. BRIEF DESCRIPTION OF THE DRAWINGS
