[0005] A fixing bracket is arranged on the base, the upper end of the fixing bracket is connected to the upper end of the vertical central shaft, and the lower end of the vertical central shaft is connected to the base.
[0006] A semicircular angle ruler is arranged above the semicircular toothed disc.
[0007] The starting ends of the arc-shaped outer slide rails are each provided with a limit stopper.
[0008] A counterweight installation position is provided on the rotating door.
[0009] The beneficial effect of the utility model is that the improved vehicle door limiter durability test device utilizes a rotating door to simulate a vehicle door, and adopts a semicircular gear plate and a motor for driving, the test is accurate, and can meet the requirements of testing the door limiters of various vehicle models under high and low temperature conditions. The entire test device has a compact structure, is easy to operate, easy to maintain, and has high reliability. BRIEF DESCRIPTION OF THE DRAWINGS
[0010] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.
