[0014] The present invention provides a measuring device for engineering design, which has the following beneficial effects: (1) In the present invention, the downward movement of the movable frame will drive the connecting frame to move downward, and the downward movement of the connecting frame will release the pressure on the triangle plate, so that the triangle plate and the protective cover will be reset under the action of the No. 1 spring. The reset of the protective cover will open the protective shell, and the actual distance will be measured when the measuring device is opened. The accurate data will be fed back to the device. At the same time, the opposite movement of the fixed plate will drive the brush to move oppositely, and the opposite movement of the brush will contact the measuring device.

[0015] (2) The invention drives the support legs to rotate when the connecting seat moves away from the mobile frame, and the support legs move away from the mobile frame so that the support seat is stably supported on the ground. The rotating plate is connected to the fixed seat and the connecting seat to prevent external interference from causing a single support leg to open too large an angle, resulting in unstable support of the equipment and affecting the support effect. At the same time, the upward movement of the sliding block drives the universal wheel to move upward, and the upward movement of the universal wheel will break away from the contact with the ground, so that the support foot is supported on the ground.

[0016] (3) In the present invention, the other end of the rotating plate rotates downward to push the slider downward, and the downward movement of the slider drives the rubber block downward. The rubber block moves downward and contacts the ground to increase resistance, thereby preventing the device from sliding along the ground during testing on an uneven or inclined ground, thereby affecting the stability of the device. At the same time, the downward rotation of the rotating plate drives the support frame to rotate downward, and the support frame contacts the ground when rotating downward. The support frame supports both sides of the support foot to prevent the device from directly falling to the ground when shaken or pushed, thereby damaging the device and increasing maintenance costs.
