[0006] Optionally, the limiting pin is made of iron, a magnetic sheet is fixedly connected to the inside of the pin groove, and the magnetic force of the magnetic ring on the limiting pin is greater than the magnetic force of the magnetic sheet on the limiting pin.

[0007] The above technical solution is adopted: by respectively arranging a magnetic ring and a magnetic sheet on the inner side of the nail groove and the limit groove, when the two flange parts are not assembled, the limit nail is not affected by the magnetic force of the magnetic ring, and the limit nail is adsorbed and contracted inside the nail groove under the magnetic force of the magnetic sheet, so that the end surface of the first flange remains flat, which is convenient for the relative rotation of the first flange part and the second flange part to complete the threaded connection. When the two are rotated, the magnetic ring is pressed to the direction away from the limit groove to avoid it affecting the extension and contraction of the limit nail. When the two flange parts are threadedly connected, the magnetic ring is brought close to the limit groove. When the nail groove and the limit groove are connected, the magnetic force of the magnetic ring on the limit nail is greater than the magnetic force of the magnetic sheet, so that the end of the limit nail is sucked into the limit groove and maintained in this state, so that the first flange part and the second flange part are fixed by the limit nail. When it is necessary to release the bite and disassemble, the magnetic ring is slid backward to release the adsorption and fixation of the limit nail, and the limit nail is reset and contracted under the magnetic force of the magnetic sheet to release the bite and fixation, and the disassembly is completed quickly.

[0012] The above technical solution is adopted: by arranging a compression spring inside the sliding groove, so that it presses the magnetic ring toward the limit groove, so that the magnetic ring can maintain a state of being in contact with the end of the limit groove when it adsorbs and fixes the limit pin, limiting the compression stroke of the compression spring, and making the magnetic ring slide and shrink a distance sufficient to release the magnetic influence on the limit pin, so that the magnetic sheet can adsorb and shrink the limit pin into the nail groove again.

[0014] 1. The quick-release flange structure is provided with a magnetic ring and a magnetic sheet on the inner side of the nail groove and the limiting groove respectively. When the two flange parts are not assembled, the limiting nail is not affected by the magnetic force of the magnetic ring. The limiting nail is adsorbed and contracted inside the nail groove under the magnetic force of the magnetic sheet. Then, the end surface of the first flange remains flat, which facilitates the relative rotation of the first flange part and the second flange part to complete the threaded connection. When the two are rotated, the magnetic ring is pressed to the direction away from the limiting groove to avoid affecting the expansion and contraction of the limiting nail. When the two flange parts are threadedly connected, The magnetic ring is placed close to the limiting groove. When the nail groove and the limiting groove are connected, the magnetic force of the magnetic ring on the limiting nail is greater than the magnetic force of the magnetic sheet. The end of the limiting nail is sucked into the limiting groove and maintained in this state, so that the first flange part and the second flange part are fixed by the limiting nail. When the bite needs to be released for disassembly, the magnetic ring is slid backward to release the adsorption and fixation of the limiting nail. The limiting nail is reset and contracted under the magnetic force of the magnetic sheet to release the bite and fixation, and the disassembly is completed quickly. Compared with the bolt fixing method, the flange structure has higher installation and disassembly efficiency.

[0015] 2. The quick-release flange structure can control the position of the magnetic ring in the sliding groove through the slider above the magnetic ring. During installation and disassembly, the magnetic ring is slid away from the first flange part to prevent it from attracting the limit pin. When the two flange parts need to be bite-fixed, the magnetic ring is slid to a position close to the first flange part so that the magnetic ring absorbs and fixes the limit pin in the limit groove to complete the bite fixation.

[0016] 3. The quick-release flange structure sets a compression spring inside the sliding groove to press the magnetic ring toward the limit groove, so that the magnetic ring can maintain a state of being in contact with the end of the limit groove when it adsorbs and fixes the limit pin, thereby limiting the compression stroke of the compression spring, so that the distance that the magnetic ring slides and contracts is sufficient to release the magnetic influence on the limit pin, so that the magnetic sheet can adsorb and contract the limit pin into the pin groove again.

[0027] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0028] like Figures 1 to 9 As shown, a quick-release flange structure includes a first flange portion 1 and a second flange portion 2. An internal thread 3 is provided on the inner side of the end portion of the first flange portion 1, and an external thread 4 is provided on the inner side of the end portion of the second flange portion 2. The first flange portion 1 and the second flange portion 2 are threadedly connected through the internal thread 3 and the external thread 4. A plurality of nail grooves 5 are provided on the outer side of the end portion of the first flange portion 1, and limiting nails 6 are provided inside the nail grooves 5. A plurality of limiting grooves 7 are provided on the outer side of the end portion of the second flange portion 2, and a sliding groove 8 is provided on the inner side of the limiting groove 7, and a magnetic ring 9 is slidably connected inside the sliding groove 8.

[0029] Embodiment 1: The first flange portion 1 and the second flange portion 2 are respectively connected to two pipeline components that need to be connected, the diameters of the first flange portion 1 and the second flange portion 2 are matched, and the inner diameter of the internal thread 3 is matched to the outer diameter of the external thread 4.

[0030] Embodiment 2: The material of the limiting nail 6 is iron, and the inside of the nail groove 5 is fixedly connected with a magnetic piece 10. The magnetic force of the magnetic ring 9 on the limiting nail 6 is greater than the magnetic force of the magnetic piece 10 on the limiting nail 6. By respectively arranging the magnetic ring 9 and the magnetic piece 10 on the inner side of the nail groove 5 and the limiting groove 7, when the two flange parts are not assembled, the limiting nail 6 is not affected by the magnetic force of the magnetic ring 9. The limiting nail 6 is adsorbed and contracted inside the nail groove 5 under the magnetic force of the magnetic piece 10, and the end surface of the first flange 1 remains flat, which facilitates the relative rotation of the first flange part 1 and the second flange part 2 to complete the threaded connection. When the two are rotated, press the magnetic ring 9 to the direction away from the limiting groove 7 to avoid its influence. The extension and retraction of the limit pin 6, when the two flange parts are threadedly connected, makes the magnetic ring 9 close to the limit groove 8. When the nail groove 5 is connected with the limit groove 7, the magnetic force of the magnetic ring 9 on the limit pin 6 is greater than the magnetic force of the magnetic sheet 10, and the end of the limit pin 6 is sucked into the limit groove 7 and maintained in this state, so that the first flange part 1 and the second flange part 2 are fixed by the limit pin 6. When it is necessary to release the bite and disassemble, slide the magnetic ring 9 backward to release the adsorption and fixation of the limit pin 6. The limit pin 6 is reset and contracted under the magnetic force of the magnetic sheet 10 to release the bite and fixation, and the disassembly is completed quickly. Compared with the bolt fixing method, the flange structure has higher installation and disassembly efficiency.

[0031] Embodiment 3: The sliding groove 8 is annular, and a slot 11 is opened on the top of the sliding groove 8. A sliding block 12 is fixedly connected to the top of the magnetic ring 9. The sliding block 12 passes through the slot 11 and is located outside the second flange part 2. The position of the magnetic ring 9 in the sliding groove 8 can be controlled by the slider 12 above the magnetic ring 9. During installation and disassembly, the magnetic ring 9 is slid away from the first flange part 1 to prevent it from attracting the limit pin 6. When the two flange parts need to be bitten and fixed, the magnetic ring 9 is slid to a position close to the first flange part 1, so that the magnetic ring 9 adsorbs and fixes the limit pin 6 in the limit groove 7 to complete the biting and fixing.

[0032] Embodiment 4: The number and position of the nail grooves 5 and the limiting grooves 7 correspond one to one, and the inner diameter of the limiting groove 7 matches the end diameter of the limiting nail 6 .

[0033] Embodiment 5: A plurality of compression springs 13 are fixedly connected inside the sliding groove 8, one end of the compression spring 13 is fixedly connected to the magnetic ring 9, and the other end of the compression spring 13 is fixedly connected to the inside of the sliding groove 8. The compression stroke of the compression spring 13 is greater than the minimum distance for the magnetic ring 9 to release the effect of the adsorption on the limit pin 6. By arranging the compression spring 13 inside the sliding groove 8, the magnetic ring 9 is pressed toward the limit groove 7, so that the magnetic ring 9 can maintain a state of being in contact with the end of the limit groove 7 when adsorbing and fixing the limit pin 6, and the compression stroke of the compression spring 13 is limited, so that the distance that the magnetic ring 9 slides and shrinks is sufficient to release the magnetic effect on the limit pin 6, so that the magnetic sheet 10 adsorbs and shrinks the limit pin 6 into the nail groove 5 again.

[0034] The working principle of the utility model is as follows:

[0035] S1. When the two flange parts are not assembled, the limit pin 6 is not affected by the magnetic force of the magnetic ring 9. The limit pin 6 is adsorbed and contracted inside the nail groove 5 under the magnetic force of the magnetic sheet 10, so that the end surface of the first flange 1 remains flat, which facilitates the relative rotation of the first flange part 1 and the second flange part 2 to complete the threaded connection. When the two are rotated, the magnetic ring 9 is pressed to the direction away from the limit groove 7 to avoid affecting the extension and contraction of the limit pin 6;

[0036] S2. When the two flange parts are threadedly connected, the magnetic ring 9 is brought close to the limiting groove 8. When the nail groove 5 is connected to the limiting groove 7, the magnetic force of the magnetic ring 9 on the limiting nail 6 is greater than the magnetic force of the magnetic sheet 10. The end of the limiting nail 6 is sucked into the limiting groove 7 and maintained in this state, so that the first flange part 1 and the second flange part 2 are fixed by the limiting nail 6. When it is necessary to release the bite and disassemble, the magnetic ring 9 is slid backward to release the adsorption and fixation of the limiting nail 6. The limiting nail 6 is reset and contracted under the magnetic force of the magnetic sheet 10 to release the bite and fixation, and the disassembly is completed quickly.

[0037] Compared with the prior art, the present invention has the following beneficial effects:

[0038] 1. The quick-release flange structure is provided with a magnetic ring 9 and a magnetic sheet 10 on the inner side of the nail groove 5 and the limiting groove 7, respectively. When the two flange parts are not assembled, the limiting nail 6 is not affected by the magnetic force of the magnetic ring 9. The limiting nail 6 is adsorbed and contracted inside the nail groove 5 under the magnetic force of the magnetic sheet 10. Then, the end surface of the first flange 1 remains flat, which facilitates the relative rotation of the first flange part 1 and the second flange part 2 to complete the threaded connection. When the two are rotated, the magnetic ring 9 is pressed to the direction away from the limiting groove 7 to avoid affecting the extension and contraction of the limiting nail 6. When the two flange parts are threadedly connected, The magnetic ring 9 is placed close to the limiting groove 8. When the nail groove 5 is connected with the limiting groove 7, the magnetic force of the magnetic ring 9 on the limiting nail 6 is greater than the magnetic force of the magnetic sheet 10. The end of the limiting nail 6 is sucked into the limiting groove 7 and maintained in this state, so that the first flange part 1 and the second flange part 2 are fixed by the limiting nail 6. When it is necessary to release the engagement and disassemble, the magnetic ring 9 is slid backward to release the adsorption and fixation of the limiting nail 6. The limiting nail 6 is reset and contracted under the magnetic force of the magnetic sheet 10 to release the engagement and fixation, and the disassembly is completed quickly. Compared with the bolt fixing method, the flange structure has higher installation and disassembly efficiency.

[0039] 2. The quick-release flange structure can control the position of the magnetic ring 9 in the sliding groove 8 through the slider 12 above the magnetic ring 9. During installation and disassembly, the magnetic ring 9 is slid away from the first flange part 1 to prevent it from attracting the limit pin 6. When the two flange parts need to be bitten and fixed, the magnetic ring 9 is slid to a position close to the first flange part 1, so that the magnetic ring 9 absorbs and fixes the limit pin 6 in the limit groove 7 to complete the biting and fixing.

[0040] 3. The quick-release flange structure sets a compression spring 13 inside the sliding groove 8 to press the magnetic ring 9 toward the limiting groove 7, so that the magnetic ring 9 can maintain a state of being in contact with the end of the limiting groove 7 when it adsorbs and fixes the limiting pin 6, and limits the compression stroke of the compression spring 13, so that the sliding and contracting distance of the magnetic ring 9 is sufficient to release the magnetic influence on the limiting pin 6, so that the magnetic sheet 10 adsorbs and contracts the limiting pin 6 into the nail groove 5 again.
