The support comprises a support base 1, a protective shell 2 and a plurality of legs 3 (four are shown). The protective housing 2 is sleeved on the supporting seat 1, the supporting seat 1 is provided with a plurality of connectors 5 (four connectors are shown in the figure) around the central axis of the supporting seat 1, the number of the connectors 5 is the same as that of the supporting legs 3, and one ends of the supporting legs 3 are respectively inserted into the connectors 5. One end of the supporting legs 3 inserted into the connecting port 5 is provided with a connecting hole 6, the connecting hole 6 is a through hole, the supporting seat 1 is provided with a plurality of groups of through holes 7 (four groups in the figure) with the same quantity as the supporting legs 3, the groups of through holes 7 are respectively aligned with the connecting holes 6 on the supporting legs 3, each group of through holes 7 and the connecting holes 6 are internally provided with a connecting pin 11 in a penetrating way, and the connecting pin 11 is used for connecting the supporting legs 3 with the supporting seat 1.
The connecting pin 11 includes an insertion rod 12, and a front end elastic block 13 and a tail end block 14 coaxially connected to two ends of the insertion rod 12, respectively, the front end elastic block 13, the insertion rod 12, and the tail end block 14 being integrally formed and made of nylon. The inserted link 12 is a round rod, the inserted link 12 penetrates through the through hole 7 and the connecting hole 6, the sectional areas of the front end elastic clamping block 13 and the tail end clamping block 14 close to one side of the inserted link 12 are both larger than the sectional area of the inserted link 12, and the front end elastic clamping block 13 and the tail end clamping block 14 are both attached to the supporting seat 1. The front end elastic clamping block 13 is provided with a deformation through groove 15, the opening direction of the deformation through groove 15 is perpendicular to the axial direction of the inserted rod 12, and the deformation through groove 15 divides the front end elastic clamping block 13 into two half clamping blocks 16. Two parallel cutting surfaces 17 are arranged on the front end elastic fixture block 13, the two cutting surfaces 17 are respectively positioned at two ends of the opening direction of the deformed through groove 15, and the cutting surfaces 17 are perpendicular to the opening direction of the deformed through groove 15. When a pressing force is applied to the front section elastic latch, the two half latches 16 can approach each other by an external force, and the entire front end elastic latch 13 can move through the through hole 7 and the connection hole 6 due to the provision of the two cutting surfaces 17.
In summary, when the user connects the leg 3 with the support base 1, first, the end of the leg 3 with the connecting hole 6 is inserted into the connecting hole 5, and the connecting hole 6 is aligned with the through hole 7; then, the front end elastic clamping block 13 of the connecting pin 11 is pressed by force, so that the two half clamping blocks 16 are close to each other, and the pressed front end elastic clamping block 13 is inserted into the counter-penetrating hole 7 and the connecting hole 6; finally, the connecting pin 11 is pushed, so that the front-end elastic clamping block 13 is moved out of the connecting hole 6 and the opposite through hole 7, the front-end elastic clamping block 13 is restored to a natural state under the action of external force, and the supporting leg 3 is connected with the supporting seat 1 by matching with the tail-end clamping block 14 and the inserted rod 12; above-mentioned whole connection process need not with the help of other instruments, and the operation is very simple and convenient, can improve the installation effectiveness of fan landing leg 3 greatly. In a similar way, when the supporting leg 3 is detached, a user only needs to extrude the front-end elastic clamping block 13 to enable the front-end elastic clamping block 13 to move into the through hole 7 and the connecting hole 6, and the connecting pin 11 is taken out from the through hole 7 and the connecting hole 6, so that the operation is convenient.
In addition, the depth of the deformation through groove 15 along the axial direction of the inserted rod 12 is greater than the thickness of the front end elastic clamping block 13 along the axial direction of the inserted rod 12, so that the front end elastic clamping block 13 can be squeezed to enable the two half clamping blocks 16 to approach each other, and further the connection of the supporting leg 3 is facilitated.
