Limiting locking structure for automobile dashboard beam fixtures

The invention discloses a limiting locking structure for automobile dashboard beam fixtures. The limiting locking structure comprises an angular support and a fixture mounting plate fixed to the front of the angular support. The top middle and upper right of the angular support are provided with two limiters, respectively; the limiters are fixed to the fixture mounting plate; two ends of each limiter are provided with two threaded through holes, respectively; an adjusting bolt is screwed in each threaded through hole; a fixing nut is screwed to each adjusting bolt; the top middle of each limiter is provided with an elongated through hole; a locking bolt is disposed in each elongated through hole; the tail end of every locking bolt is screwed to the angular support; a locknut is screwed to each locking bolt. The problem that due to the limiters having no locking structure, the automobile dashboard beam fixtures are adjusted inaccurately or the size of a product is inaccurate after adjusting is solved; a dashboard beam has more stable and reliable size during production; the sizes of various mounting holes are within an allowable dimensional tolerance range; automobiles are safer and more reliable.
