DETAILED DESCRIPTION
[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] Example 1
[0028] See also Figure 1-3 , a triangular positioning detection ruler, comprising a detection ruler group 1 and a connecting shaft 3, the detection ruler group 1 comprising a first ruler 101, one end of the first ruler 101 is rotatably connected to a second ruler 102 via a connecting shaft 3, the other end of the second ruler 102 is rotatably connected to a third ruler 103 via a connecting shaft 3, the first ruler 101, the second ruler 102 and the third ruler 103 are all provided with scale marks 2, and the length of the third ruler 103 is greater than that of the first ruler 101 and the second ruler 102;
[0029] In the invention of the utility model, a measuring ruler group 1 is provided, and the measuring ruler group 1 uses a first ruler 101, a second ruler 102 and a third ruler 103 to achieve the purpose of importing the dimensions on the drawing into the actual application scene, and uses the structural characteristics of the triangle to install the cable pile perpendicular to the baseline, and the third ruler 103 is designed to be longer than the first ruler 101 and the second ruler 102, so that it can be applied more widely, and the measuring ruler group 1 can still be used normally when the angle between the cable pile and the deck is an obtuse angle.
[0030] The first scale 101, the second scale 102 and the third scale 103 are all made of transparent materials;
[0031] By using a transparent design for the first scale 101, the second scale 102 and the third scale 103, readings can be taken on both the front and back sides, further improving the convenience of use.
[0032] One end of the first scale 101 and the third scale 103 connected to the connecting shaft 3 is provided with an arc chamfer;
[0033] By setting an arc chamfer, the arc chamfer can reduce the sharpness of the sharp corners of the first ruler 101 and the third ruler 103 to prevent scratches on users. At the same time, the arc chamfer can be used to ensure that the diagonals of the first ruler 101 and the third ruler 103 will not exceed the range of the second ruler 102 when they rotate, which can effectively ensure that the second ruler 102 is placed parallel to the deck.
[0034] Example 2
[0035] refer to Figure 4 , Figure 5 Specifically, one end of the first ruler 101 is provided with a protractor 104, the first ruler 101 is rotatably connected to a connecting shaft 3 corresponding to the position of the center of the protractor 104, and a fourth ruler 106 is fixedly connected under the connecting shaft 3;
[0036] In this embodiment, the angle between the fourth ruler 106 and the first ruler 101 can be detected by using the protractor 104. The fourth ruler 106 is rotated to the same degree using the angle between the deck and the mooring pile obtained on the drawing. Then, the first ruler 101 is fitted to the deck and the fourth ruler 106 is fitted to the mooring pile, so that the mooring pile can be quickly positioned. Compared with the length measurement in the first embodiment, the positioning work can also be completed by using angle measurement, and the efficiency is higher.
[0037] The connecting shaft 3 is provided with an indicator needle 105, which is slidably matched with the angle ruler 104;
[0038] By setting the indicator needle 105, the indicator needle 105 can rotate synchronously with the fourth scale 106 using the connecting shaft 3, and can more accurately indicate the degree of the protractor 104, so that the user can intuitively determine the angle between the fourth scale 106 and the first scale 101, further improving the accuracy and convenience of positioning.
[0039] Example 3
[0040] refer to Figure 6 , Figure 7Specifically, a placement cavity 5 is provided in the connection shaft 3, a locking component 4 is provided in the placement cavity 5, the locking component 4 is fitted with the detection ruler group 1, the locking component 4 includes an extrusion component 401, a spring sheet 402 and two friction blocks 403, the two friction blocks 403 penetrate the connection shaft 3 and are slidably connected thereto, the spring sheet 402 is located between the friction blocks 403, and applies an elastic force to push the friction blocks 403 outward, the extrusion component 401 is sleeved on the top of the spring sheet 402, and an inner hole smaller than the spacing of the spring sheets 402 is opened in the extrusion component 401;
[0041] In this embodiment, a spring sheet 402 and a friction block 403 are used. In a fixed state, the spring sheet 402 squeezes the friction block 403 to both sides, so that the friction block 403 fits with the detection ruler group 1, and is fixed by friction, thereby realizing rapid positioning of the detection ruler group 1 after it is opened, and ensuring the stability of the detection ruler group 1. When the limit needs to be released, the extrusion piece 401 is pressed downward, and the extrusion piece 401 uses the inner hole to squeeze the spring sheet 402 inward, so that the spring sheet 402 contracts. At this time, the friction block 403 exerts its extrusion force and releases the friction limit with the detection ruler group 1.
[0042] A tension spring 404 is provided between the friction blocks 403 , and the tension spring 404 applies an inward pulling force to the friction blocks 403 , and the elastic force of the tension spring 404 is smaller than the spring sheet 402 ;
[0043] By setting the tension spring 404, the tension spring 404 plays a limiting role on the friction block 403. When the friction block 403 loses the squeezing of the spring sheet 402, the tension spring 404 will use its own pulling force to pull the friction block 403 inward, so that the friction block 403 is received in the placement cavity 5, thereby realizing the automatic separation of the friction block 403 and the detection ruler group 1.
[0044] Working principle:
[0045] Embodiment 1: When using (such as Figure 3 As shown), place the detection ruler group 1 on the drawing, align the second ruler 102 with the deck line on the drawing, and then align the first ruler 101 with the mooring bollard line. Finally, use the third ruler 103 to measure and record the values of the farthest ends of the second ruler 102 and the first ruler 101. Then place the second ruler 102 on the deck where the mooring bollard needs to be installed, and align the first ruler 101 with the mooring bollard. Then move the third ruler 103 close to the top of the first ruler 101, and adjust the positions of the third ruler 103 and the first ruler 101 according to the values on the drawing. When the value of the third ruler 103 is aligned with the top of the first ruler 101, the first ruler 101 is in a vertical state with the baseline, and the mooring bollard is placed parallel to the first ruler 101.
[0046] Embodiment 2: When in use, the angle between the mooring pile and the deck is obtained according to the drawing, and then the fourth ruler 106 is rotated. The fourth ruler 106 rotates through the indicator needle 105 at the top of the connecting shaft 3. When the degree of the indicator needle 105 is the same as the value on the drawing, the rotation of the fourth ruler 106 is stopped, and the first ruler 101 is placed parallel to the deck. At this time, the fourth ruler 106 is perpendicular to the baseline, and the mooring pile and the fourth ruler 106 are placed parallel.
[0047] Embodiment 3: The spring sheet 402 will use its own elastic force to squeeze the friction block 403, so that the friction block 403 fits with the detection ruler group 1 and fixes it. When the detection ruler group 1 needs to be moved, the extrusion piece 401 is pressed, and the extrusion piece 401 uses the inner hole to squeeze the spring sheet 402 inward, so that the spring sheet 402 shrinks and separates from the friction block 403. After the friction block 403 loses the extrusion, it moves inward under the drive of the tension spring 404, retracts into the placement cavity 5, and separates from the detection ruler group 1. At this time, the detection ruler group 1 can move freely.
[0048] As described above, the utility model sets the first ruler, the second ruler and the third ruler. When the mooring pile is installed, it needs to be perpendicular to the baseline, and the deck will be inclined at a certain angle. At this time, the mooring pile and the deck will form a fixed angle that is not equal to 90 degrees. On the drawing, the second ruler is used to measure a certain distance of the deck to make one side of the triangle, and the distance is the axial spacing of the connecting shafts at both ends of the second ruler. Then, the first ruler is used to measure a certain distance of the mooring pile to make the other side of the triangle, and a triangle is drawn. The length of the third side is measured using the third ruler, and then the same length is drawn on the deck and the mooring pile on the ship. Then, the angle of the mooring pile is adjusted. When the value of the third ruler is the same as the value on the drawing, the mooring pile is perpendicular to the baseline. At the same time, by setting the fourth ruler and the protractor, the angle between the bollard and the deck is obtained on the drawing, and then the fourth ruler is rotated. When the fourth ruler rotates, the indicator needle is driven to rotate synchronously through the connecting shaft. When the indicator needle moves to the same degree as the drawing on the protractor, the rotation of the fourth ruler is stopped, and then the first ruler is placed on the deck, and the fourth ruler is placed on the side of the bollard. When the bollard is parallel to the fourth ruler, the bollard is perpendicular to the baseline.
[0049] The above are only specific embodiments of the invention, but the technical features of the invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the invention to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the invention.
