[0028] As Figure 1 , Figure 2 and Figure 3 shown, a portable measuring ruler for engineering detection includes: a vertical ruler 20, the vertical ruler 20 is in the shape of a rectangular straight ruler, and a scale is provided on one side of the front wall surface of the vertical ruler 20. This is the prior art, so it will not be elaborated here.
[0029] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, a conversion structure, the conversion structure can convert the vertical ruler 20 into two working states, and the conversion structure includes: a fixed plate 30 and a movable plate 33, the fixed plate 30 is rotatably connected to the wall surface of the vertical ruler 20, the movable plate 33 is rotatably connected to one side wall surface of the fixed plate 30, and the fixed plate 30 and the movable plate 33 can form a semi-circular frame.
[0030] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the movable plate 33 can be turned over on the wall of the fixed plate 30 so that the rear wall of the movable plate 33 and the rear wall of the fixed plate 30 are in contact with each other, and scales are provided at the arc edges of the front walls of the fixed plate 30 and the movable plate 33. The first adjustment groove 31 and the second adjustment groove 34 can adapt to the thickness of the vertical ruler 20. The vertical ruler 20 is rotatably connected in the first adjustment groove 31, and the vertical ruler 20 can rotate in the first adjustment groove 31 and the second adjustment groove 34. When the movable plate 33 and the fixed plate 30 form a semicircular frame state, the second adjustment groove 34 and the first adjustment groove 34 are connected. The groove 31 will be connected, and the conversion structure also includes a clamping block 35, a handle 36, a clamping column 37 and a clamping block 38. The clamping block 35 is symmetrically fixedly connected to one side of the front wall of the movable plate 33, the handle 36 is fixedly connected to one side of the front wall of the fixed plate 30, the clamping column 37 is rotatably connected to the side wall of the handle 36, and the clamping block 38 is fixedly connected to the side wall of the clamping column 37. When the fixed plate 30 and the movable plate 33 form a semicircular frame, the clamping column 37 will be located between the symmetrical clamping blocks 35, and the symmetrical spacing of the clamping blocks 35 can adapt to the size of the clamping column 37.
[0031] In actual use, when it is necessary to measure the angle, first flip the flap 33 to contact the side wall of the fixed plate 30, then the first adjustment slot 31 will be connected to the second adjustment slot 34, and the clamping column 37 will be between the symmetrical clamping blocks 35, and the clamping block 38 will be rotated to contact the side wall of the clamping block 35 to fix the position of the flap 33, then the device can be picked up by the handle 36 to measure the angle, and when measuring the angle, the vertical ruler 20 can be rotated in the first adjustment slot 31 so that the center of the front wall of the vertical ruler 20 points to The scale on the wall of the fixed plate 30 or the movable plate 33 can be used for measuring angles. When it is necessary to measure the length, firstly, the contact between the clamping block 38 and the clamping block 35 is cancelled by rotating the clamping block 38, and the rear wall of the movable plate 33 is turned around the base axis 32 to contact the rear wall of the fixed plate 30, and then the vertical ruler 20 is turned over until the side wall of the vertical ruler 20 is flush with the bottom of the fixed plate 30. At this time, the device can be taken for measuring the length. When the device is idle, the vertical ruler 20 can be turned over in the first adjustment slot 31 so that the vertical ruler 20 is folded in the first adjustment slot 31;
[0032] In summary, by setting up a conversion structure, it is possible to convert into two different states for measuring length or angle, because the conversion structure can achieve two usage forms by flipping the movable plate 33 and cooperating with the vertical ruler 20, and the vertical ruler 20 can be folded into the wall of the fixed plate 30 when idle, so this solution is more convenient to carry and can replace the ruler and protractor for measurement.
[0033] like Figure 1 , Figure 2 and Figure 4As shown, the rear wall surface of the fixed plate 30 is provided with a fixed structure, which includes a receiving groove 40, a base column 41, a stopper 42, a rotating column 43, a clamping plate 44 and a clamping groove 45. The receiving groove 40 is opened through the rear wall surface of the fixed plate 30, the base column 41 is fixedly connected in the receiving groove 40, the stopper 42 is symmetrically fixedly connected in the receiving groove 40, the rotating column 43 is rotatably connected to the wall surface of the base column 41, the clamping plate 44 is rotatably connected to the end of the rotating column 43, the clamping groove 45 is symmetrically opened on both sides of the clamping plate 44, and the stopper 42 is T-shaped. The receiving groove 40 can adapt to the size of the rotating column 43 and the card plate 44. When the card plate 44 enters the receiving groove 40, the stopper 42 will be stuck in the card groove 45. When the rear wall surface of the fixed plate 30 and the rear wall surface of the movable plate 33 contact each other, the front wall surface of the card plate 44 can contact the front wall surface of the movable plate 33 by rotating. The front wall surface of the vertical ruler 20 is fixedly connected with a finger block 21, which is an isosceles triangle block. The front wall surface of the vertical ruler 20 is also penetrated by a marking groove 22, which is a rectangular groove.
[0034] In specific use, before the rear wall of the fixed plate 30 contacts the rear wall of the movable plate 33, the clamping plate 44 is turned over by the rotating column 43 with the base column 41 as the center of the circle so as to be turned out of the receiving groove 40. At this time, the rear wall of the fixed plate 30 will contact and overlap with the rear wall of the movable plate 33. The clamping plate 44 is rotated to a vertical state, and the bottom of the clamping plate 44 will contact the wall of the movable plate 33 to adjust the position of the movable plate 33. When adjusting the rotation of the vertical ruler 20, the finger block 21 will point to the scales of the walls of the fixed plate 30 and the movable plate 33 for indication, and the accurate value can be obtained by marking in the marking groove 22 area with a marker pen;
[0035] In summary, by setting up a fixing structure, the position of the flap 33 after flipping can be ensured to be fixed, which can improve the stability of the device during operation. The marking groove 22 and the finger block 21 can facilitate the staff to mark and obtain data during use.
[0036] Working principle: When the angle needs to be measured, first flip the movable plate 33 to contact the side wall surface of the fixed plate 30. At this time, the first adjustment groove 31 will communicate with the second adjustment groove 34, and the clamping post 37 will be between the symmetric clamping blocks 35. Rotate the clamping block 38 to contact the side wall surface of the clamping block 35 to fix the position of the movable plate 33. At this time, the device can be picked up by the handle 36 for angle measurement. When measuring the angle, the vertical ruler 20 can be rotated in the first adjustment groove 31 so that the scale on the wall surface of the fixed plate 30 or the movable plate 33 pointed by the center of the front wall surface of the vertical ruler 20 can be used for angle measurement. When the length needs to be measured, first rotate the clamping block 38 to cancel the contact between the clamping block 38 and the clamping block 35, and flip the rear wall surface of the movable plate 33 with the base shaft 32 as the center to contact the rear wall surface of the fixed plate 30. Then flip the vertical ruler 20 until the side wall surface of the vertical ruler 20 is flush with the bottom of the fixed plate 30. At this time, the device can be picked up for length measurement. When the device is idle, the vertical ruler 20 can be flipped in the first adjustment groove 31 so that the vertical ruler 20 is folded in the first adjustment groove 31. Before the rear wall surface of the fixed plate 30 contacts the rear wall surface of the movable plate 33, rotate the clamping plate 44 with the rotating column 43 as the center with the base column 41 as the center to flip it out of the receiving groove 40. At this time, the rear wall surface of the fixed plate 30 will contact and coincide with the rear wall surface of the movable plate 33. Rotate the clamping plate 44 to a vertical state, and the bottom of the clamping plate 44 will contact the wall surface of the movable plate 33 to fix the position of the movable plate 33. When adjusting the rotation of the vertical ruler 20, the finger block 21 will point to the scales on the wall surfaces of the fixed plate 30 and the movable plate 33 for indication, and accurate values can be obtained by marking with a marker pen in the marking groove 22 area.
