[0003] In the material measurement of engineering cost, the measuring ruler is the core tool for measuring the size, angle and shape of objects. Traditional engineering measuring rulers are usually single-structure rulers or tape measures that only support unidirectional measurement. Multiple operations or tool changes are required to complete multi-directional dimension measurement, which is inefficient. Therefore, we propose a portable engineering measuring ruler to solve the above-mentioned problems. Utility Model Content

[0006] The connecting indicator engages with the adjacent measuring ruler.

[0007] Preferably, the measuring ruler includes a main ruler body, on both sides of which a first sliding groove and a second sliding groove are provided. The main ruler body has a second locking groove that cooperates with another measuring ruler. The two measuring rulers have a first locking groove and a third locking groove on their respective sides. The cross-shaped insert is engaged with the adjacent side of the two measuring rulers through the combined first locking groove and third locking groove.

The locking block body engages with the adjacent measuring ruler, and the multiple anti-slip rubbers are interference-fitted with the surface of the adjacent measuring ruler.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The measuring ruler used in this project adopts a modular structure, which allows it to be easily laid flat and packed into a small bag during storage, greatly improving its portability.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] Please see Figures 1-6 This utility model provides a portable engineering measuring ruler, including a connecting indicator 2 and two measuring rulers 1 that engage with each other. The measuring rulers 1 are also provided with cross-shaped inserts 3 on both sides, and the two cross-shaped inserts 3 engage with the two sides of the two measuring rulers 1 respectively.

[0029] Among them, the connecting indicator 2 and the adjacent measuring ruler 1 are engaged with each other.

[0030] In this embodiment, the measuring ruler 1 includes a main ruler body 11. The main ruler body 11 has a first sliding groove 15 and a second sliding groove 17 on both sides. The main ruler body 11 has a second locking groove 13 that cooperates with another measuring ruler 1. The two measuring rulers 1 have a first locking groove 12 and a third locking groove 14 on both sides respectively. The cross-shaped insert 3 engages with the adjacent side of the two measuring rulers 1 through the combined first locking groove 12 and third locking groove 14.

[0031] Both sides of the measuring ruler 1 are provided with scale display surfaces 16 indicating the movement length of the indicator 2 connected within the first slot 12 and the first slide groove 15.

[0032] The connecting indicator 2 includes a connecting block 21, a positioning ring 26 is installed inside the connecting block 21, a threaded rod 22 is rotatably connected to the positioning ring 26, a threaded ring 25 is threadedly connected to the threaded rod 22, and a connecting rod 23 is rotatably connected to both the threaded ring 25 and the positioning ring 26, and one end of two adjacent connecting rods 23 is hinged to each other.

[0033] Among them, several connecting rods 23 are also equipped with indicator scales.

[0034] The measuring ruler 1, in conjunction with the connecting indicator 2, allows the connecting rod 23 to work with the scale display surface 16 to find the dimensions that best fit the shape of the engineering cost item.

[0035] In this embodiment, the cross-sections of the multiple first slide grooves 15 and the second slide grooves 17 are all L-shaped, and the cross-section of the connecting block 21 is Z-shaped.

[0036] This design allows both ends of the connecting block 21 to be combined with the measuring ruler 1.

[0037] In this embodiment, the end of the threaded rod 22 away from the positioning ring 26 passes through and extends out of the connecting block 21. A rotating knob 24 is fixed on the extended end of the threaded rod 22. Both the threaded rod 22 and the rotating knob 24 are rotatably connected to the connecting block 21.

[0038] A knob is provided for easy adjustment from the outside of the connecting block 21.

[0039] In this embodiment, the cross-shaped insert 3 includes a locking block body 31, on which a plurality of anti-slip rubbers 32 are installed. The locking block body 31 engages with the adjacent measuring ruler 1, and the plurality of anti-slip rubbers 32 are interference-fitted with the surface of the adjacent measuring ruler 1.

[0040] The main body 31 of the locking block makes the measuring ruler 1 more stable, and the anti-slip rubber 32 further improves the overall stability.

[0041] The working principle and usage process of this utility model: This device is convenient to carry because of its modular structure. When storing it, only a small bag is needed to lay out the connecting indicator 2, the cross-shaped insert 3 and the measuring ruler 1 and put them in the bag.

[0042] When normal use is required, first insert the second slots 13 of the two main ruler bodies 11 into each other. At this time, the two adjacent first slots 12 and third slots 14 will combine to form a cross, which can perfectly fit the cross insert 3. The two anti-slip rubbers 32 on the block body 31 will further reinforce the shape of the two measuring rulers 1, so that the two measuring rulers 1 form a cross shape. You can directly hold the measuring ruler 1 to measure the corresponding dimensions of the items in the project cost according to the actual needs. The cross shape design can measure the dimensions of multiple directions at the same time, and it is more convenient to take it out. When flat measurement is required, you only need to remove one of the measuring rulers 1.

[0043] When some items are irregular or need to be measured in length and width at the same time, the connecting block 21 is inserted into the first groove 15 or the second groove 17 according to the surface of the item in the project cost. Then, turning the knob 24 will drive the threaded rod 22 to rotate. When the threaded ring 25 is constrained by the positioning ring 26 and the two connecting rods 23, the threaded ring 25 will move left and right along the threaded rod 22. At this time, it will take the connecting rod 23 to expand and contract into different triangles. With the help of the scale display surface 16, the size that is more suitable for the shape of the item in the project cost can be found.

[0044] Example 2

[0045] See Figure 7 When it is necessary to measure the surface of some special objects, the connecting indicator 2 can be used as an intermediate connecting medium. The two measuring rulers 1 can be selected according to the actual needs, and the corresponding first slide 15 and second slide 17 can be inserted into the connecting indicator 2 to form different shapes before the next measurement is carried out.

[0046] The electronic components and modules used in this utility model can all be parts that are commonly used in the market and can achieve the specific functions in this case. The specific models and sizes can be selected and adjusted according to actual needs.

[0047] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
