Abstract
The utility model discloses a dovetail groove wedge block connection structure, which is used for connecting and locking two connected pieces tightly and comprises two connected pieces and a pair of tightly locked wedge blocks, wherein the two connected pieces are respectively provided with dovetail through grooves and positions of the two dovetail through grooves are mutually plumbed and crossed or are not plumbed and crossed. The pair of tightly locked wedge blocks are respectively arranged into the dovetail through grooves of the two connected pieces through dovetail wedge heads of both ends. Tight support screw nails pass through one tightly locked wedge block, the other tightly locked wedge block is tightly supported through the end part of the tight support screw nails and the two connected pieces are connected and locked tightly. The connection structure is simple, connective positions can be adjusted at will, and connection is rapid, firm and stable.
Description
Technical field
The utility model belongs to the linkage structure that is used in uses such as exhibition apparatus, building and ornament materials, is specifically related to a kind of dovetail groove voussoir linkage structure.
Background technique
Adopting the exhibition apparatus fast construction exhibition of standard piece and prefabricated is the direction of puting on display the boundary now, has the minimizing waste, thereby saves resource, environmental protection, characteristics of high efficiency.In the building of existing exhibition apparatus, between the section bar linkage structure be threaded, connecting plate connection etc., all need do corresponding processing to connected piece during connection at link position, and connecting the position, back is difficult for adjusting, there is complex structure, connect inconvenience, the problem of soundness difference is further improved.
Summary of the invention
The purpose of this utility model is to provide a kind of dovetail groove voussoir linkage structure at the deficiency of prior art existence, and simple in structure, link position can be adjusted arbitrarily, connects rapidly firm stable.
The technical solution of the utility model is as follows:
A kind of dovetail groove voussoir linkage structure, it comprises two connected pieces and a pair of locking wedge block, on two connected pieces the dovetail groove is arranged respectively, mutual square crossing of two dovetail grooves or non-perpendicular intercross arrangement, a pair of locking wedge block is put into respectively in the dovetail groove of two connected pieces by the dovetail shaped wedge head at two ends, hold out against screw and pass a wherein locking wedge block, hold out against another relative locking wedge block, connect locking two connected pieces with its end.
In this structure, the last hyposphene head of described locking wedge block can be the overall structure that interfixes, also can be to form rotating linkage structure by screw, fixed connection structure can adapt to and is fixedly coupled angle, screw connecting mode can make the various connection angles of locking wedge block self adaption, and such design is in order to be suitable for the needs of free adjusting connected piece connection angle.
This linkage structure is applicable to two section bars, two posts or beam etc. is connected that owing to be to connect by the dovetail groove, tie point can be adjusted arbitrarily; And, or to the adjustment of the two ends wedge head relative angle of locking wedge block, can be conveniently connected piece be done mutual intersection, the connection of vertical and even various angles such as be parallel to each other mutually according to the position difference of dovetail groove on two connected pieces; Simultaneously, this linkage structure has automatic fastening effect, and it is big, solid and reliable to connect surface of contact, and not high to the required precision of two connected pieces.
