fig. 2 is a schematic view of a connection structure between a main body and a fixture block of the coupler for an industrial fan, which is convenient to disassemble and assemble;
fig. 3 is a schematic structural diagram of a main body of the coupler for an industrial fan, which is convenient to disassemble and assemble;
in the figure: 1. the fan comprises a main body, 2. a shaft hole, 3. an impeller, 4. a first spring, 5. a clamping block, 6. a second spring, 7. an extending block, 8. a bolt, 9. a bearing, 10. a pressing block and 11. a fan blade.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
As shown in fig. 1-3, a coupling convenient to disassemble and assemble for an industrial fan comprises an impeller 3 with a clamping hole inside and a plurality of fan blades 11 arranged on the impeller 3, and is characterized by further comprising a main body 1 with a shaft hole 2 at one end and a fixing mechanism arranged in the main body 1 and used for fixing the impeller 3 and the main body 1;
the fixing mechanism comprises a bolt 8 matched with the clamping hole and arranged on the main body 1, a pressing block 10 arranged in the main body 1, a bearing 9 for connecting the bolt 8 with the pressing block 10 and four popping assemblies arranged in the main body 1 and abutted against the pressing block 10. The bolt 8 is clamped in the clamping hole, so that the impeller 3 drives the bolt 8 to rotate when rotating, and the pressing block 10 extrudes the ejection assembly.
Specifically, the pop-up assembly comprises a clamping block 5 abutted against the pressing block 10, a first spring 4 arranged in the main body 1, two ends of the first spring are respectively fixedly connected with the main body 1 and the clamping block 5, and a locking assembly arranged on the clamping block 5 and used for fixing the impeller 3 and the clamping block 5. The pressing block 10 extrudes the clamping block 5 to push the clamping block 5 out of the main body 1, and simultaneously extrudes the first spring 4, and the locking assembly works at the moment, so that the clamping block 5 is clamped with the impeller 3.
Specifically, the locking assembly comprises a second spring 6 arranged in the fixture block 5 and an extending block 7 fixedly connected with the second spring 6 and used for clamping the impeller 3 and the fixture block 5. The second spring 6 presses the protrusion block 7, so that the protrusion block 7 protrudes out of the fixture block 5, and the fixture block 5 is clamped with the impeller 3.
Specifically, lubricating oil is coated between the pressing block 10 and the fixture block 5.
Specifically, the cross section of the shaft hole 2 is in the shape of a regular hexagon.
This a theory of operation for easy dismounting's shaft coupling of industry fan: main part 1 passes through shaft hole 2 and hub connection, overlaps impeller 3 in main part 1, and fixed establishment work, bolt 8 card are in blocking the hole for impeller 3 drives bolt 8 when rotating and rotates, lets briquetting 10 extrusion pop out the subassembly, pops out subassembly work, and briquetting 10 extrusion fixture block 5 releases main part 1 with fixture block 5, makes impeller 3 fixed with main part 1, extrudees first spring 4 simultaneously, and locking Assembly work this moment makes fixture block 5 block with impeller 3.
Compared with the prior art, this a shaft coupling for easy dismounting of industry fan, through fixed establishment, the fixed effect of equipment impeller 3 that can be convenient fast or dismantlement impeller 3 and this shaft coupling is better.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
