Specific embodiment
Below in conjunction with the accompanying drawings the utility model is specifically described.
Fig. 1 is the structural representation of polygon clip described in the utility model;Fig. 2 is fastening block described in the utility model
Internal structure schematic diagram;Fig. 3 is the overlooking the structure diagram of card article described in the utility model, as Figure 1-3, a kind of polygon
Clip, including card article 1, fastening block 2, fastening bolt 3, it is characterised in that the quantity of the card article 1 is multiple, the plurality of card
Head and the tail connection, in polygonal annular structure, is connected between two adjacent card articles 1, the fastening block 2 bar 1 by fastening block 2 successively
Side be connected with 3 bearing of the fastening bolt, the fastening bolt 3 is threadedly coupled with the card article 1, on the fastening block 2
It is provided with non-return block 6.
Non-return tooth bar 8 is installed on the non-return block 6,6 " U "-shaped structure of the non-return block, the non-return tooth bar 8 are embedded in
In the " u "-shaped structure of the non-return block 6, connected by buffer spring 9 between the non-return tooth bar 8 and non-return block 6, the buffering
Spring 9 is stage clip, and the quantity of the buffer spring 9 is multiple, and the plurality of buffer spring 9 is along the axial direction of the non-return tooth bar 8
The linear array distribution in direction, the two ends of the non-return tooth bar 8 are embedded in the non-return block 6 and are slided with the non-return block 6 and connected
Connect, the side of the card article 1 is provided with sawtooth 7, and the sawtooth 7 is connected with the non-return tooth bar 8 engagement.
The card article 1 is metal strip structure, and the radial section of the card article 1 is the rectangular configuration with unfilled corner 10, institute
Unfilled corner 10 is stated for arcuate structure, the fastening bolt 3 is embedded in the unfilled corner 10 and the fastening bolt 3 and the unfilled corner 10
Mutually agree with.
Two adjacent card articles 1 intersect and are embedded in and the both sides through the fastening block 2, the fastening bolt 3
