Referring to fig. 1, fig. 1 is a schematic structural diagram of a measuring device according to the present invention; as shown in fig. 1, the invention provides a folding measurement device, which comprises a first support arm 1, a second support arm 2 and a third support arm 3 with equal length, wherein the first support arm 1, the second support arm 2 and the third support arm 3 are all hinged through the same rotating shaft, a first limit post 14 is arranged at the free end of the first support arm 1, a second limit post 24 is arranged at the free end of the second support arm 2, a third limit post 34 is arranged at the free end of the third support arm 3, a support sleeve 4 is arranged on the rotating shaft, a support column 41 is arranged in the support sleeve 4, a support rod sleeve 42 is further hinged on the support column 41, a support rod 43 is arranged in the support rod sleeve 42, a measurement component 5 is arranged on the support rod 43, a scale mark for marking the length is arranged on the support rod 43, the measurement component comprises a first slide block 51 and a second slide block 55 which are arranged on the support rod 43, a first measurement component is arranged on the first slide block 51, a second measurement component is arranged on the second slide block 55, and the length of the first measurement component is longer than that of the second measurement component; the first measuring assembly comprises a first support 52 connected with a first sliding block 51, a first rod sleeve 53 is hinged on the first support 52, and a first measuring rod 54 is arranged in the first rod sleeve 53; the second measuring assembly comprises a second support 56 connected with a second sliding block 55, a second rod sleeve 57 is hinged on the second support 56, and a second measuring rod 58 is arranged in the second rod sleeve 57; the second support 56 has a height less than the first support 52; the first measuring rod 54 is marked with a scale indicating the length of the first measuring rod 54, and the second measuring rod 58 is marked with a scale indicating the length of the second measuring rod.
Therefore, when the diaphragm spring is placed, the first support arm 1, the second support arm 2 and the third support arm 3 with equal lengths are matched with the first limit post 14, the second limit post 24 and the third limit post 34, as the three support arms respectively fix one point on the circumference of the diaphragm spring, the diaphragm spring is fixed, the hinge position of the three support arms is the center of the circle, namely the position of the support sleeve 4 is the center of the circle of the diaphragm spring, the length difference between the first sliding block 51 and the second sliding block 55 on the support rod 43 is read, the difference value is used as one right angle side of the right triangle, the value measured by the first measuring rod 54 and the value measured by the second measuring rod 58 are used as the other right angle side of the right triangle, the inclination angle can be obtained quickly through a trigonometric function, the measurement operation is simple, the accuracy is high, and the product quality is improved.
