Utility model content
The purpose of this utility model be in order to solve shortcoming in the prior art, and a kind of automobile object proposed is consolidated
Surely core-theaded type fixing bolt is used.
To achieve these goals, the utility model employs following technical solution：A kind of automobile object fixation punching
Formula fixing bolt, including expansion bolt, the expansion bolt bottom is welded with expansion piece, and the connection of expansion bolt and expansion piece
Place is provided with gasket, and internal thread, a kind of automobile object fixation core-theaded type are provided on the inner surface wall of the expansion piece
Fixing bolt further include with the matching used internal core rod of automobile object fixation core-theaded type fixing bolt, the internal core rod it is outer
The external screw thread that cooperation internal thread uses is provided on table wall, cross mouth is begun at the top center of the internal core rod, it is described interior
Limited block is welded with, and nut bore is offered on limited block on appearance wall at the top of core bar, the expansion bolt upper surface offers
Limiting slot, and the clamping block that cooperation limited block uses is welded in limiting slot, being provided with attaching nut hole on the clamping block makes
Fixing bolt.
As further describing for above-mentioned technical proposal：
The length of the internal core rod and the equal length of expansion bolt.
As further describing for above-mentioned technical proposal：
There are three the expansion piece is set altogether, and spacing is equal between any two for three expansion pieces.
As further describing for above-mentioned technical proposal：
There are two the limited block is set altogether, and two limited blocks are in same horizontal line.
As further describing for above-mentioned technical proposal：
There are two the clamping block is set altogether, and two clamping blocks are symmetrical about the vertical center line of expansion bolt.
In the utility model, the core-theaded type fixing bolt first, by internal core rod screw thread rotation to expansion bolt, passing through
The object of automobile is fixed in expansion bolt, is fixed in contrast to traditional bolt type, fixation will more stability, secondly in
Core bar is fixed by external screw thread with the internal thread screw thread rotation opened up on expansion piece so that the core-theaded type fixing bolt internal core rod can
With dismounting, in contrast to traditional fixed expansion bolt, using enhanced convenience is wanted, limited block and clamping block are finally provided with, it will
Internal core rod rotates to the inside of expansion bolt, can be internal by the nut bore on limited block by the fixing bolt on clamping block
Core bar is fixed, and further improves the fixed stability of core-theaded type fixing bolt.
