Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing and preferred embodiment.

Shown in Fig. 1 to 6, it is a kind of simple and easy banding device, comprise hoop 1, characteristics of the present utility model are: also comprise first link 2 that is fixed on hoop 1 one ends, be fixed on second link 5 of the hoop the other end, first swing part 3 that is rotationally connected with first link and second swing part 4 that is rotationally connected with first swing part and second link respectively; Second swing part is fixedly connected with second link or separate by connection set.

In the present embodiment, be provided with one at first link 2 with the abutting end of first swing part 3 and be connected projection 21, thereby form the first step 22 that concaves; The two ends of first swing part are provided with first opening 31 and second opening 32, the first and connect projections and insert in first opening and by first pivot pin 6 and be rotationally connected, and first link and first swing part are rotationally connected; The abutting end of second swing part 4 and first swing part is provided with a contiguous block 41 that outwards protrudes, thereby form the second step 42 that concaves, contiguous block inserts in second opening and by second pivot pin 8 and is rotationally connected, second swing part and first swing part are rotationally connected, and the both sides of first swing part are resisted against between first step and the second step; Port at contiguous block is provided with connection opening 411, below second link 5, be provided with a projection 51 and double-screw bolt 52, this projection inserts in the connection opening and by the 3rd pivot pin 7 and is rotationally connected, on second swing part, have the hole corresponding with double-screw bolt, connection set is a bolt 6, second swing part and second link are by bolt or separate, thereby fan screen is fixed or taken apart, as shown in Figure 7.Above first swing part 3, also be provided with the step 33 that holds hoop 1, above second swing part 4, be provided with and hold second link 5 and bind round 1 groove 43.

During use, as shown in Figure 7, be the electric fan that adopts the assembling of the utility model banding device to connect, wherein second link 5 and second swing part 4 connect firmly by bolt 6, before releasing connects firmly, and the akinesia of this device, guard is the banding state all the time.When tripping out bolt, after removing the connecting firmly of second link and second swing part, manually with second swing part in the direction of arrows toward drop-down (as shown in Figure 2), running by linkage mechanism, state as shown in Figure 5, connect first link 2 and first swing part 3 and second swing part this moment and realize separating with the two ends of hoop 1, the front and back guard realizes removing the banding state.Otherwise, banding front and back guard, the pressure that promptly manually second swing part made progress by the running of linkage mechanism, moves to state shown in Fig. 3,4, with bolt second swing part is connected with second to connect firmly again, and realizes the banding state.Easy to operate, reliable.

Though aforesaid the present invention describes as an embodiment, but this is not limited to an above-mentioned suitable embodiment, those of ordinary skill in the art can carry out various changes and implement not breaking away under the aim situation of the present invention of claim scope, these changes are implemented to be included in the claim scope of being put down in writing by key element of the present invention.
