Abstract
The utility model discloses an adjustable bolted connection structure, including bolt, nut and by the connecting piece, be the slot by at least one bolt hole on by the connecting piece in the connecting piece, the long limit of slot is the cusp, and two locking pieces are installed at long square hole through the tooth interlock on the tooth on it and the slot, installs two back locking pieces towards the arc surface encirclement of the bolt one end both sides at the bolt. The utility model discloses can overcome current bolted connection because of the problem by the unable installation of connecting piece bolt hole dislocation for do not reached at the machining precision by the connecting piece and still can adopt bolted connection under the condition of requirement, thereby reduction in production cost to a certain extent improves production efficiency.
Description
Technical field
The utility model relates to a kind of bolt fastening structure, particularly relates to the connection that a kind of adjustable bolt linkage structure is mainly used in steel structure.
Background technique
The Placement that steel structure is conventional has welding, riveted joint is connected with bolt.Bolt connects due to its easy construction, repeatedly can install, dismantles and applied widely.But bolt connects higher to the making required precision of connected piece, when the geometric accuracy of connected piece do not reach require time, when just can not ensure to install, the bolt hole position of connected piece is just right, and bolt hole dislocation just makes bolt incapability pass and cannot install, therefore the certain condition that is subject to bolts limits.
Summary of the invention
The purpose of this utility model is to provide a kind of adjustable bolt linkage structure, and this adjustable bolt linkage structure can overcome existing bolt and connect the problem cannot installed because of the dislocation of connected piece bolt hole.
Adjustable bolt linkage structure provided by the invention, comprise bolt, nut and connected piece, described bolt is fixed by nut through after the bolt hole on connected piece, bolt hole in described connected piece at least one connected piece is rectangular hole, the long limit of rectangular hole is dentation, two lock dogs are engaged with the tooth on rectangular hole by the tooth on it and are arranged in rectangular hole, install latter two lock dog is enclosed in bolt both sides towards the arc surface of bolt one end.
Further, the tooth on connected piece rectangular hole and the tooth on lock dog are rectangular teeth.
The utility model adopts and the bolt hole on a connected piece is processed as profile of tooth rectangular hole, and with the position of lock dog fixing bolt in rectangular hole, existing bolt can be overcome and connect the problem cannot installed because of the dislocation of connected piece bolt hole, make connected piece still can be with bolts when machining accuracy does not reach requirement, thus cost of production can be reduced to a certain extent, enhance productivity.

Embodiment
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, the utility model comprises bolt 1, nut 2, connected piece A3, connected piece B4, lock dog A5 and lock dog B6, described connected piece A3 and connected piece B4 is processed with the bolt hole passed for bolt 1, bolt hole A7 wherein on connected piece A3 is rectangular hole (namely the cross section in hole is rectangular), the rectangular dentation in long limit of rectangular hole.Bolt hole B8 on connected piece B4 is the circular hole usually adopted.Lock dog A5 and lock dog B6 is arranged in rectangular hole, side relative with the rectangular hole rectangle flank of tooth on it is processed with the rectangle teeth groove that can be engaged with rectangular hole rectangular teeth, its end face relative with bolt 1 is arc surface, lock dog A5 and lock dog B6 is fixed in the rectangular hole of connected piece A3 by the rectangular teeth on it with the coordinating of rectangular teeth of rectangular hole, its thickness is identical with the degree of depth of rectangular hole, and after installing, the arc surface of lock dog A5 and lock dog B6 is enclosed in the both sides of bolt 1.
During installation, first bolt 1 is passed connected piece A3 and connected piece B4, then after being fixedly connected component A3 position, lock dog A5 and lock dog B6 is put into the position of rectangular bolt hole A7 remaining position lock(ing) bolt 1, last fastening nut 2, lock dog A5 and lock dog B6 is pressed in rectangular bolt hole A7 by the nut 2 tightened.Lock dog A5 and lock dog B6 can be upwards prized with screw-driver during dismounting.
The above is only the good mode of execution of the utility model, but protection domain of the present utility model is not limited thereto, any based on scheme of the present utility model with conceive the improvement carried out and replace and all should be encompassed in protection domain of the present utility model.
