For solving the deficiency that exists in the prior art, the utility model provides a kind of door opening deflection test device of effective raising measuring accuracy, and it is simple in structure, and is easy to operate.
For realizing above-mentioned purpose; The door opening deflection test device of the utility model; To the panel beating bearing load conquassation that surrounds door opening and the conquassation amount that produces respond to; It comprises that clamping the friction tight first tight portion of pincers and second with the panel beating that surrounds door opening clamps tight portion; Be connected with first connecting rod and the second connecting rod that is slidingly matched because of plug-in mounting, coaxial line is provided with between the tight portion in the first tight portion of pincers and second pincers, on the plug-in mounting structure of first connecting rod and second connecting rod, be provided with the sensor that displacement that the relative second connecting rod of first connecting rod is produced because of slip is responded to.
As the qualification to aforesaid way, described sensor is the rod-pulling type displacement transducer.
As the further qualification to aforesaid way, the pull bar of described rod-pulling type displacement transducer is by stretching out in the body that is connected on the second connecting rod, and with the push rod contact matching that is fixed on the first connecting rod, the axis of said pull bar and the parallel axes of first connecting rod.
As improvement to the utility model, in second connecting rod, be provided with the ball of second connecting rod rolling relatively, when described first connecting rod inserts in the second connecting rod, cooperate with the ball rolling.
As the improvement to aforesaid way, described ball is distributed on the hollow wall of second connecting rod.
Adopt such scheme; Through first connecting rod and second connecting rod plug-in mounting fit form, during the conquassation amount that produces in the panel beating bearing load conquassation that constitutes door opening, the first tight portion of pincers and the tight portion of second pincers bear this conquassation amount and the time first connecting rod and second connecting rod produce corresponding displacement; This displacement is responded to through sensor; Supply transacter to receive the signal of handling to produce, it is simple in structure, and this structure only adopts the connecting rod form; Effectively reduced usage space, the generation of mutual interference when having avoided adopting multiple arrangement that the door opening deflection is tested at the same time; In addition,, can effectively reduce relative friction force of sliding between first connecting rod and the second connecting rod, effectively raise measuring accuracy through on the hollow wall of second connecting rod, setting up ball.
