DETAILED DESCRIPTION

[0021] The specific embodiments of the present application will be further described in detail below with reference to the accompanying drawings, so that the technical scheme of the present application is easier to understand and master.

[0022] Reference Figure 1 The present embodiment provides a new magnetic pressure relief ring, which comprises an inner ring and an outer ring 1, the inner ring is coaxially and rotatably connected to the inner side of the outer ring 1; the inner ring comprises an upper ring body 21 and a lower ring body 22, the upper ring body 21 is threadedly connected with the lower ring body 22; when the upper ring body 21 is connected with the lower ring body 22, the inner peripheral walls and the outer peripheral walls of the two are flush, respectively.

[0023] The inner peripheral wall of the outer ring 1 is coaxially provided with an outer ring groove 12 at a lower position, and the bottom of the lower ring body 22 is formed with an annular flange 222; the annular flange 222, the outer ring groove 12 and the bottom of the upper ring body 21 jointly form an annular limiting groove; and the annular limiting groove is provided with a Teflon ring 6 or a plurality of balls. In this way, the outer ring 1 and the inner ring can be limited by the Teflon ring 6 or the plurality of balls, so as to prevent them from being separated.

[0024] The inner peripheral wall of the upper ring body 21 is coaxially provided with a first annular groove 211 at a lower position, and the groove wall of the first annular groove 211 is provided with a first threaded portion 212; and the outer peripheral wall of the lower ring body 22 is correspondingly provided with a second threaded portion 221. During installation, only the inner ring body and the outer ring 1 body need to be screwed.

[0025] The outer peripheral wall of the upper ring body 21 is provided with a plurality of first embedding grooves 24 at a position opposite to the first annular groove 211 in the circumferential direction; a first magnetic member 3 is fixedly embedded in the embedding groove, and the first magnetic member 3 is a magnet. The outer peripheral wall of the upper ring body 21 is provided with a second annular groove 23 at an upper position, and the second annular groove 23 is communicated with the first embedding groove 24. The provision of the second annular groove 23 not only facilitates CNC machining, but also facilitates the installation of the first magnetic member 3.

[0026] The inner peripheral wall of the outer ring 1 is coaxially provided with a third annular groove 11 at an upper position, and two fixing blocks 4 are fixedly arranged in the third annular groove 11 in a spaced manner, and a second magnetic member is movably arranged between the two fixing blocks 4. The second magnetic member comprises an arc-shaped base 51 and a plurality of second magnets 52, and the arc-shaped base 51 is coaxial with the third annular groove 11; the outer peripheral wall of the arc-shaped base 51 is provided with a second embedding groove 511 in the circumferential direction in a spaced manner, and the plurality of second magnets 52 are fixedly embedded in the second embedding groove 511 in a one-to-one manner.

[0027] Through the above arrangement, when the outer ring 1 rotates, the plurality of first magnetic members 3 can repeatedly attract and repel the second magnetic member, so that the second magnetic member collides with the outer ring 1 or the first magnetic member 3, thereby emitting sound and achieving the effect of pressure reduction.

[0028] In addition, in order to prevent the second magnetic member from interfering with the slot of the first embedding groove 24 and causing the outer ring 1 to rotate and be stuck, chamfers 512 are arranged at both ends of the arc-shaped base 51.

[0029] Preferably, of course, the above is only a typical example of the present application, and in addition to this, the present application can have other various specific implementation manners, and any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of protection required by the present application.
