Description

Technical Field

[0001] The utility model relates to the technical field of disassembly rings, in particular to a quickly disassembly ring for an impeller. Background Art

[0002] A removal ring is a tool component used to remove an impeller. It is typically an annular metal component with an inner diameter that fits the impeller shaft or hub, and an outer diameter that is shaped and sized for ease of use. The removal ring is typically made of a material with high strength and toughness, such as high-quality carbon steel or alloy steel, to withstand the forces involved during removal.

[0003] In the prior art, when the disassembly ring is in use, several disassembly ring structures are fixed by bolts. When disassembly is required, the several disassembly ring structures are separated by bolts, thereby facilitating disassembly and installation.

[0004] However, when inspecting and replacing accessories, due to long-term high and low pressure, large and small flow reciprocating work, the axial force is large, the disassembly ring is locked on the shaft, and it is not easy to disassemble, which makes the disassembly of the disassembly ring more troublesome. Utility Model Content

[0005] The purpose of the utility model is to provide a disassembly ring for an impeller that can be disassembled quickly, thereby solving the problem that the disassembly ring in the prior art is troublesome to disassemble.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A quickly detachable disassembly ring for an impeller comprises two semicircular disassembly ring bodies, the surfaces of both disassembly ring bodies being provided with a slot, a ring being passed through the interior of the slot, a gap between the two disassembly ring bodies being 30°, a fixing mechanism being provided between the ring and the gap between the two disassembly ring bodies, the surface of one of the disassembly ring bodies being rotatably connected to a circular arc-shaped extrusion piece, one end of which being fixedly connected to an extrusion block.

[0008] Preferably, the fixing mechanism includes two extension rods fixedly connected to one end of one of the disassembly ring bodies, a quadrilateral adjustment frame is passed between the two extension rods, and a fixing rod is fixedly connected to the inner bottom of the adjustment frame, and the fixing rod is passed through the two ends of the ring.

[0009] Preferably, the bottom of the adjustment frame and the bottom of the extension rod are elastically connected via an extrusion spring.

[0010] Preferably, the ends of the two disassembly ring bodies that are close to each other are fixedly connected to an extension plate, and the rings fit against the tops of the extension plates.

[0011] Preferably, a leakage groove is provided on the surface of the extrusion sheet, and a blocking block is fixedly connected to the surface of one of the disassembly ring bodies, and the blocking block is inserted into the leakage groove.

[0012] Preferably, a limiting rod is fixedly connected to the interior of the slot.

[0013] The utility model has the following beneficial effects:

[0014] When replacing accessories and disassembling the impeller, it is necessary to first disassemble the disassembly ring and remove the axial force. The ordinary three-piece disassembly ring body is changed to two semicircular disassembly ring bodies, which are matched with the shaft to process a 3-degree self-locking angle. The two semicircles are separated in the middle and processed at a 30-degree angle. The disassembly ring mainly bears the axial force and the radial force is very small. When the disassembly ring is disassembled, the extrusion block is a structure that can enter the 30-degree angle. After being subjected to external force, pressure is applied to the adjustment frame, so that the fixing rod on the adjustment frame is separated from the ring. The ring is no longer fixed, allowing the disassembly ring body to be separated. Therefore, the disassembly ring is punched open from the 30-degree angle by the extrusion block, which saves effort, is quick and convenient, and improves the time for replacing accessories.

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] Reference Figure 1-5 A disassembly ring for an impeller that can be quickly disassembled comprises two semicircular disassembly ring bodies 1. The surfaces of the two disassembly ring bodies 1 are provided with a card slot 2. The inside of the card slot 2 is provided with a ring 3. When the disassembly ring is needed, the ring 3 can be stuck in the card slot 2 so that the two disassembly ring bodies 1 can be combined for use, and the ring 3 can prevent the two disassembly ring bodies 1 from separating. The gap between the two disassembly ring bodies 1 is 30 degrees. A fixing mechanism 4 is provided between the ring 3 and the gap between the two disassembly ring bodies 1. When the two disassembly ring bodies 1 are assembled, the ring 3 inside the card slot 2 is used. When connecting, the two ends of the ring 3 can be fixed by the fixing mechanism 4, thereby ensuring that the two disassembly ring bodies 1 will not separate, ensuring the stability of the disassembly ring body 1, and the surface of one disassembly ring body 1 is rotatably connected with an arc-shaped extrusion piece 5, and one end of the extrusion piece 5 is fixedly connected with an extrusion block 6. When the two disassembly ring bodies 1 need to be separated, the extrusion piece 5 can be rotated so that the extrusion block 6 enters between the two disassembly ring bodies 1, and then the extrusion block 6 is hammered so that the extrusion block 6 separates the fixing mechanism 4, so that the two disassembly ring bodies 1 can be easily separated for disassembly.

[0024] Furthermore, the fixing mechanism 4 includes two extension rods 401 fixedly connected to one end of one of the disassembly ring bodies 1, and a quadrilateral adjustment frame 402 is passed between the two extension rods 401. The inner bottom of the adjustment frame 402 is fixedly connected with a fixing rod 403, and the fixing rod 403 is passed through the two ends of the ring 3. When it is necessary to fix the two disassembly ring bodies 1 through the ring 3, the two ends of the ring 3 can be placed up and down into the adjustment frame 402 on the extension rod 401, and then the adjustment frame 402 can be raised so that the fixing rod 403 inside the adjustment frame 402 passes through the two ends of the ring 3, fixing the two ends of the ring 3 so that they will not separate, thereby fixing the disassembly ring body 1 through the ring 3.

[0025] Furthermore, the bottom of the adjustment frame 402 and the bottom of the extension rod 401 are elastically connected by an extrusion spring 404. During actual operation, after the fixing rod 403 inside the adjustment frame 402 passes through the two ends of the ring 3, the elastic force of the extrusion spring 404 can be used for support, so that the fixing rod 403 will not easily detach from the two ends of the ring 3, thereby continuously ensuring the fixation of the disassembly ring body 1 and ensuring the function of the disassembly ring body 1.

[0026] Furthermore, the ends of the two disassembly ring bodies 1 that are close to each other are fixedly connected with an extension plate 405, and the ring ring 3 fits in with the top of the extension plate 405. The extension plate 405 can ensure that when the adjustment frame 402 moves downward by knocking the extrusion block 6, the fixing rod 403 can be conveniently blocked by the extension plate 405 when leaving the ring ring 3 and will not move with the fixing rod 403, ensuring that the fixing rod 403 can easily leave the ring ring 3, thereby conveniently separating the disassembly ring body 1.

[0027] Furthermore, a leakage groove 7 is provided on the surface of the extrusion sheet 5, and a blocking block 8 is fixedly connected to the surface of one of the disassembly ring bodies 1. The blocking block 8 is inserted into the leakage groove 7. When it is necessary to knock the extrusion block 6 to extrude the adjustment frame 402, the extrusion sheet 5 can be rotated first. During this process, the blocking block 8 passes through the leakage groove 7, ensuring that the extrusion block 6 can be continuously located between the gaps of the two disassembly ring bodies 1. Then, by knocking the extrusion block 6, the extrusion block 6 is lowered to extrude the adjustment frame 402, thereby facilitating the separation of the disassembly ring body 1.

[0028] Furthermore, a limiting rod 9 is fixedly connected to the interior of the slot 2 , and the limiting rod 9 can conveniently limit the ring 3 to prevent the ring 3 from easily escaping from the slot 2 .

[0029] In summary:

[0030] When the disassembly ring is needed, the two disassembly ring bodies 1 can be put together first, and then the ring ring 3 enters the card slot 2, and the limiting rod 9 also prevents the ring ring 3 from being easily separated from the card slot 2, and the two disassembly ring bodies 1 are brought close to each other, and then the fixing rod 403 and the extrusion spring 404 in the fixing mechanism 4 make the two ends of the ring ring 3 continuously fixed, so that the two disassembly ring bodies 1 can be conveniently fixed. When the two disassembly ring bodies 1 need to be separated, the extrusion piece 5 can be rotated to make the extrusion block 6 close to the adjustment frame 402. In this process, the blocking block 8 will enter the leaking hole on the extrusion piece 5. The groove 7 is used to stabilize the position of the extrusion block 6, and then the extrusion block 6 is knocked. The extrusion block 6 will apply pressure to the adjustment frame 402 on the extension rod 401. The adjustment frame 402 drops after being subjected to external force, so that the fixing rod 403 is separated from the ring 3 through the cooperation of the extension plate 405, so that after the ring 3 is loosened, the disassembly ring body 1 can be separated, so that the disassembly ring body 1 can be conveniently used. Through the above structure, the disassembly ring body 1 can be conveniently fixed and separated, and the disassembly and assembly is labor-saving, fast and convenient, which reduces the time for replacing accessories and makes the use of the disassembly ring body 1 more convenient.
