Abstract
The utility model discloses a kind of sheet material expanding unit, comprise the recessed link and convex link that cooperatively interact, recessed link to be enclosed within convex link and to be fixed by connecting bolt and nut thereof, it is characterized in that: two shoulders of described recessed link and convex link are all through there being clamping bolt, the end winding support of clamping bolt has pad, and the screw that described connecting bolt is corresponding with clamping bolt is counter sink.This novel rotating sheet material expanding unit, can be fixed two boards material and connects, and realizes expansion board face and amasss.
Description
Technical field
the utility model relates to a kind of sheet material expanding unit, multi-sheets to be carried out connection expansion.
Background technique
need to use in the industry of sheet material in furniture, engineering construction etc. at present, often need sheet material opposite joint to be spliced into larger flat board, or the sheet material of different-thickness is butted into an entirety.Complete the splicing of this opposite joint general adopt screw directly fastening or adopt corner brace to connect, the mode such as welding and other links, these Placements all can cause expendable destruction to sheet material, and impact repeatedly uses.
Summary of the invention
In order to overcome the defect of Placement of existing sheet material expansion, the utility model aims to provide a kind of firm and easy-to-dismount sheet material expanding unit
The technological scheme that sheet material expanding unit of the present utility model adopts is:
A kind of sheet material expanding unit, comprise the recessed link and convex link that cooperatively interact, recessed link to be enclosed within convex link and to be fixed by connecting bolt and nut thereof, it is characterized in that: two shoulders of described recessed link and convex link are all through there being clamping bolt, the end winding support of clamping bolt has pad, and the screw that described connecting bolt is corresponding with clamping bolt is counter sink.
Further, convex link top protuberance insert bottom recessed link recess in, be provided with the screw of through recessed link and convex link, connecting bolt is through being fixed by nut after this screw, and pad is rubber sheet gasket.
After adopting above structure, sheet material expanding unit of the present utility model, can be fixed two boards material and connect, and realize expansion board face and amass, and structure is simple, quick detachable.
Accompanying drawing explanation
Fig. 1 is the cross section structure schematic diagram of sheet material expanding unit embodiment of the present utility model.
Embodiment
The description of symbols related in accompanying drawing: recessed link 1, convex link 2, connecting bolt 3, nut 31, clamping bolt 4, rubber sheet gasket 41.
Be described in detail below in conjunction with the technological scheme of accompanying drawing to the sheet material expanding unit of the utility model embodiment.
As shown in Figure 1, a kind of sheet material expanding unit, comprise the recessed link 1 and convex link 2 that cooperatively interact, recessed link to be enclosed within convex link and to be fixed by connecting bolt 3 and nut 31 thereof, two shoulders of described recessed link 1 and convex link 2 are all through there being clamping bolt 4, the end winding support of clamping bolt 4 has rubber sheet gasket 41, and the screw that described connecting bolt 3 is corresponding with clamping bolt 4 is counter sink.
During connection, first sheet material to be connected is snapped in respectively the left and right sides between recessed link 1 and convex link 2, after tightening connecting bolt 3 and nut 31 thereof, then the clamping bolt 4 of both sides is tightened respectively.
Owing to having connecting bolt 3 and clamping bolt 4 dual fastening, can make sheet material connection more solid and reliable.
