Abstract
The invention relates to the technical field of fans, in particular to a fastener looseness-preventing device. The fastener looseness-preventing device comprises a motor shaft, an impeller and a fastening bolt, and is characterized by being provided with a positioning washer and a looseness-preventing washer, wherein a through hole is formed in the center of the positioning washer; a positioning clamping groove is formed in the side wall of the positioning washer; the looseness-preventing washer is triangular; a punched hole is formed in the center of the looseness-preventing washing; one angle of the looseness-preventing washer is vertically bent, so that a baffle is formed; another angle of the looseness-preventing washer radially extends and is reversely and vertically bent relative to the baffle, so that a positioning plate is formed; the fastening bolt penetrates through the punched hole of the looseness-preventing washer and the through hole of the positioning washer; the impeller is fixed on the motor shaft through the looseness-preventing washer and the positioning washer; one side of the fastening bolt is in contact with the baffle of the looseness-preventing washer; the positioning plate of the looseness-preventing washer is clamped in the positioning clamping groove, so that the purpose that the looseness of the fastening bolt is prevented during the frequently starting of a motor, and mechanical accidents are avoided. The fastener looseness-preventing device has the advantages of simple structure, attractiveness in appearance, high convenience in manufacture, high safety, high reliability and the like.
Description
Technical field
The present invention relates to blower fan technical field, specifically a kind of fastening piece loosening device for fan motor axle and impeller.
Background technique
In existing fan industry, connection for motor shaft and impeller is usually adopted compression spring or taper pad and is tightened by bolt, this locking and prevent the mode of movement from can meet the demands for for the slow-speed of revolution or startup blower fan infrequently, but blower fan that is higher for rotating speed or frequent starting then can not ensure to loosen or prevent mobile security, if rotating component can not securely locking, impeller so likely will be caused to come off installation shaft, easily form mechanical accident.
Summary of the invention
The object of the invention is to solve above-mentioned the deficiencies in the prior art, provide that a kind of structure is simple, appearance looks elegant, easy to make, safe and reliable fastener locking device.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of fastener locking device, comprise motor shaft, impeller and clamping bolt, it is characterized in that being provided with locating washer and check washer, locating washer center is provided with through hole, sidewall is provided with locating groove, check washer is triangular in shape, check washer center is provided with perforation, check washer wherein one jiao vertically with check washer be bent into baffle plate, wherein the radial also opposing flaps reverse vertical that extends in another angle is bent into positioning plate, clamping bolt is through the perforation of check washer and the through hole of locating washer and be fixed on motor shaft by check washer and locating washer by impeller, the spiral shell hat side of clamping bolt and the baffle plate of check washer inconsistent, the positioning plate of check washer is stuck in locating groove, reach loosening of the clamping bolt preventing motor in frequent starting process, avoid mechanical accident.
The present invention, owing to adopting said structure, has that structure is simple, appearance looks elegant, an advantage such as easy to make, safe and reliable.
accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the sectional drawing of A-A in Fig. 1.
Reference character: motor shaft 1, impeller 2, clamping bolt 3, locating washer 4, check washer 5, locating groove 6, baffle plate 7, positioning plate 8.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further described:
As shown in drawings, a kind of fastener locking device, comprise motor shaft 1, impeller 2 and clamping bolt 3, it is characterized in that being provided with locating washer 4 and check washer 5, locating washer 4 center is provided with through hole, sidewall is provided with locating groove 6, check washer 5 is triangular in shape, check washer 5 center is provided with perforation, check washer 5 wherein one jiao vertically with check washer 5 be bent into baffle plate 7, wherein radial also opposing flaps 7 reverse vertical that extends in another angle is bent into positioning plate 8, clamping bolt 3 is through the perforation of check washer 5 and the through hole of locating washer 4 and be fixed on motor shaft 1 by check washer 5 and locating washer 4 by impeller, the spiral shell hat side of clamping bolt 3 and the baffle plate 7 of check washer 5 inconsistent, the positioning plate 8 of check washer 5 is stuck in locating groove 6, reach and prevented motor loosening at frequent starting process clamping bolt 3, avoid mechanical accident.When mounted, clamping bolt 3 is through the perforation of check washer 5 and the through hole of locating washer 4 and be fixed on motor shaft 1 by check washer 5 and locating washer 4 by impeller 2 in the present invention, rotates clamping bolt 3 make-up torque.Turn up the baffle plate 7 of check washer 5 one jiaos, make baffle plate wrap clamping bolt 3, such clamping bolt 3 will by fixing tightly, and impeller 2 is also compacted can not move.
The present invention is when making, and locating washer 4 and check washer 5 all can press tool blankings, and locating washer 4 can on-the-spot bending positioning plate 8, and one jiao of needs of parcel clamping bolt 3 are finally turned up.
The present invention, owing to adopting said structure, has that structure is simple, appearance looks elegant, an advantage such as easy to make, safe and reliable.
