Description

Technical Field

[0001] This utility model relates to the field of building engineering testing technology, and in particular to a ruler for testing the quality of building engineering. Background Technology

[0002] Currently, construction quality inspection refers to the activity of testing and determining the quality characteristics of materials, components, equipment, and the physical quality and functionality of construction projects in accordance with relevant national laws, regulations, mandatory engineering construction standards, and design documents. As one of the quality inspection tools, the construction quality inspection ruler is mainly used for construction and completion quality inspection of engineering projects such as building construction, decoration and renovation, bridge construction, and equipment installation. Through the measurement of the quality inspection ruler, a direct understanding and judgment of the quality of construction projects can be obtained.

[0003] For example, in the prior art, there is a ruler for quality inspection in construction engineering (publication number: CN220853353U). In specific use, through the extension mechanism, when the main body of the ruler is extended, the upward squeezing of the moving block drives the locking rod to move upward and separate it from the main body of the ruler. Then, the airtight door is opened, and the extended ruler placed inside the main body of the ruler is poured out. Then, the moving toggle block drives the connecting rod and the protrusion and inclined block at its end to separate. At this time, the fixing rod automatically retracts under the action of the third spring, maintaining this state and installing the snap-fit ​​connector at one end of the extended ruler at the other end of the main body of the ruler. Then, the toggle block is released, and the second spring drives the fixing rod to reset and snap-fit ​​with the main body of the ruler. The remaining extended rulers can be installed and fixed in the same way, thereby ensuring the stability of the connection between the extended ruler and the main body of the ruler. At the same time, it also greatly increases the applicability of this device and meets different usage needs.

[0004] However, the existing detection rulers have limited functionality and cannot measure the angle between two planes to be detected in actual use. This further requires operators to carry multiple measuring tools and exchange them, which seriously affects the effectiveness of the device and the operator's detection efficiency. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the prior art and to propose a ruler for quality inspection of building engineering.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a ruler for inspecting the quality of building engineering, comprising two ruler bodies symmetrically distributed, with adjustment grooves communicating with the interior on the opposite surfaces of the two ruler bodies, and adjustment bars slidably connected in each of the two adjustment grooves, with coaxial and equal-sized hinge holes respectively opened on the overlapping parts of the two adjustment bars, and positioning bolts provided in the two hinge holes, the positioning bolts passing through the two hinge holes in sequence, and the outer surfaces extending outward are threaded with positioning bolts, one of the adjustment bars having an angle disk on its outer surface near the positioning bolt, the outer surface of the angle disk having degree scale lines arranged in a circumferential array, and the other adjustment bar also having a horizontally set angle pointer pointing to the angle disk fixedly connected to its outer surface near the positioning nut.

[0007] Preferably, each of the two measuring ruler bodies has a first fixing hole on its outer surface near the opening of the adjusting groove, which communicates with the internal adjusting groove. Each of the adjusting strips has a plurality of second positioning holes at equal intervals on its outer surface. The first fixing hole and one of the second positioning holes are internally threaded with a fixing bolt.

[0008] Preferably, one of the measuring scale bodies has a mounting socket fixedly connected to its upper surface, and a rubber block is inserted into the mounting socket. The other measuring scale body has a connecting groove inside, above the adjustment groove, which connects to the outside through two connecting ports. One connecting port is located on the upper surface of the measuring scale body, and the other connecting port is located on the outer surface of the measuring scale body away from the positioning nut. A guide rod is fixedly connected inside the connecting groove. An abutment block that passes through the upper connecting port and extends outward is slidably connected to the guide rod. A fixing plate that passes through the side connecting port and extends outward is fixedly connected to the outer surface of the abutment block inside the connecting groove. A handle is provided on the fixing plate.

[0009] Preferably, the outer surface of the measuring ruler body, which has a connecting groove inside, also has an inner mounting recess at the same height as the side connecting opening. The fixing plate is fixedly connected to two threaded rods on the outer surface of the inner mounting recess. The ends of the two threaded rods are flush with the outer surface of the measuring ruler body. The handle has mounting holes corresponding to the threaded rods. The threaded rods pass through the mounting holes and are threaded with mating nuts on their outwardly extending outer surfaces.

[0010] Preferably, the angle disc is located between the adjusting bar and the positioning nut, and three positioning posts are fixedly connected to the outer surface of the measuring ruler body on which the angle disc is provided. The angle disc has three positioning holes corresponding to the positioning posts, and the angle disc is sleeved on the positioning posts through the three positioning holes.

[0011] Preferably, straight graduation grooves are provided on the outer surfaces of both measuring scale bodies, and symmetrically arranged L-shaped mounting blocks are fixedly connected to the lower surfaces of both measuring scale bodies and to positions near the openings of the adjustment grooves, respectively. Equal and coaxial mounting holes are provided on the parallel outer surfaces of the two L-shaped mounting blocks.

[0012] Preferably, one of the measuring ruler bodies has a mounting groove on its outer surface where a straight scale groove is provided, and a bubble level is fixedly connected inside the mounting groove.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, when measuring the included angle between two planes, the adjusting strip is pushed to slide within the adjusting groove of the measuring ruler body, adjusting the effective contact length of the two rulers and fitting them to the plane to be measured. After rotating the ruler to adjust the included angle, a positioning bolt is passed through the coaxial hinge hole of the overlapping part of the adjusting strip, and then the extended length of the adjusting strip is locked and fixed by the positioning nut. At this time, the angle disk and the angle pointer cooperate, and the pointer accurately points to the circumferential array scale line on the disk, allowing direct reading of the included angle value without additional tools. This improves the convenience and accuracy of measurement while adapting to plane measurement scenarios with different spacing and angles.

[0014] 2. In this utility model, the handle is fitted onto two threaded rods outside the fixing plate through the mounting hole. The ends of the threaded rods are flush with the outer surface of the measuring scale body. Tightening the mating nut secures the handle. The fixing plate is fixedly connected to the contact block and passes through the connecting port on the side of the measuring scale body. Pushing the handle causes the contact block to slide along the guide rod in the connecting groove, allowing it to pass through the upper connecting port and fit tightly against the plane to be measured, ensuring the fit between the measuring scale body and the plane. During disassembly, loosening the mating nut removes the handle, avoiding interference with measurement or scratching the plane due to the protruding structure, further improving the effectiveness and applicability of the device.

[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] like Figure 1-8 As shown, a ruler for inspecting the quality of construction engineering includes a ruler body 1. There are two ruler bodies 1, which are symmetrically distributed. The opposing surfaces of the two ruler bodies 1 are respectively provided with adjustment grooves 2 that are connected to the interior. Adjustment strips 3 are slidably connected in both adjustment grooves 2. The overlapping parts of the two adjustment strips 3 are respectively provided with coaxial and equal-sized hinge holes 4. Positioning bolts 5 are provided in the two hinge holes 4. The positioning bolts 5 pass through the two hinge holes 4 in sequence, and the outer surfaces extending outward are threaded with positioning nuts 6. An angle disk 7 is also provided on the outer surface of one adjustment strip 3 near the positioning nut 6. The outer surface of the angle disk 7 is provided with degree scale lines 8 in a circumferential array. The other adjustment strip 3 is also fixedly connected to the outer surface of the positioning nut 6 with a horizontally set angle pointer 9 that points to the angle disk 7. One of the measuring scale bodies 1 has a mounting socket 13 fixedly connected to its upper surface. A rubber block 14 is inserted into the mounting socket 13. The other measuring scale body 1 has a connecting groove 15 inside, above the adjustment groove 2, which connects to the outside through two connecting ports. One connecting port is located on the upper surface of the measuring scale body 1, and the other connecting port is located on the outer surface of the measuring scale body 1 away from the positioning nut 6. A guide rod 16 is fixedly connected inside the connecting groove 15. An abutment block 17 that passes through the upper connecting port and extends outward is slidably connected to the guide rod 16. A fixing plate 18 that passes through the side connecting port and extends outward is fixedly connected to the outer surface of the abutment block 17 inside the connecting groove 15. A handle 19 is provided on the fixing plate 18.

[0020] The specific usage method of this solution is as follows: When measuring the angle between two planes, push the adjusting strip 3 to slide in the adjusting groove 2 of the measuring ruler body 1. This can adjust the effective contact length of the two measuring ruler bodies 1 so that they fit the two planes to be measured respectively. After rotating the measuring ruler body 1 to change the included angle, the positioning bolt 5 passes through the coaxial hinge hole 4 of the overlapping part of the two adjusting strips 3 in sequence, and then locks it with the positioning nut 6. This can fix the extension length of the two adjusting strips 3 respectively. At this time, the angle disk 7 on one adjusting strip 3 cooperates with the angle pointer 9 on the other adjusting strip 3. The circumferential array degree scale line 8 on the outer surface of the angle disk 7 can be accurately pointed to by the angle pointer 9. The included angle value of the two planes can be read directly without additional auxiliary tools, which significantly improves the convenience and accuracy of the included angle measurement and is suitable for plane measurement scenarios with different spacing and different angles. Furthermore, during use, the rubber block 14 inside the mounting socket 13 on one of the measuring scale bodies 1 is attached to one of the planes to be measured. The rubber block 14 is installed in the mounting socket 13 by plugging in, which can buffer the impact force during attachment and at the same time increase the friction with the plane to prevent slippage. Hold the handle 19 on the other measuring scale body 1 and push the fixing plate 18 to drive the abutment block 17 to slide along the guide rod 16 in the connecting groove 15, so that the abutment block 17 passes through the upper connecting port and fits tightly against the other plane to be measured. The side connecting port is for the sliding of the fixing plate 18. The guide rod 16 provides space for movement, while the sliding trajectory of the contact block 17 is smooth, avoiding deviation. After the two measuring ruler bodies 1 are stably attached to the two planes through the rubber block 14 and the contact block 17 respectively, the included angle can be measured through the hinge structure and the angle reading component. This design can effectively prevent the measuring ruler from separating from the plane or shifting during the measurement process, ensuring the accuracy of the included angle measurement benchmark. At the same time, the flexible attachment of the rubber block 14 and the rigid sliding of the contact block 17 are combined to adapt to planes of different materials and flatness, broadening the applicable scenarios for included angle measurement and improving the accuracy of the measurement results.

[0021] like Figure 3 and Figure 4As shown, the outer surfaces of the two measuring ruler bodies 1 near the opening of the adjustment groove 2 are provided with first fixing holes 10 that communicate with the internal adjustment groove 2. The outer surfaces of each adjustment bar 3 are provided with several second positioning holes 25 at equal intervals. The first fixing hole 10 and one of the second positioning holes 25 are internally threaded with fixing bolts 12.

[0022] The purpose of this design is as follows: After the adjusting strip 3 slides within the adjusting groove 2 of the measuring scale body 1 to a position that matches the distance between the two planes, the first fixing hole 10 near the opening of the adjusting groove 2 on the measuring scale body 1 aligns with the corresponding hole among the several second positioning holes 25 equidistantly distributed on the outer surface of the adjusting strip 3. The fixing bolt 12 is then threaded into the aligned first fixing hole 10 and second positioning hole 25 and tightened, thus locking the length of the adjusting strip 3 and preventing displacement of the adjusting strip 3 during measurement, which could cause the measuring scale body 1 to loosen its contact with the plane. This structure ensures the relative position of the two measuring scale bodies 1 remains stable during measurement, reduces the angle measurement error caused by structural swaying, and improves the reliability of the measurement results.

[0023] like Figure 2 , Figure 5 and Figure 8 As shown, the outer surface of the measuring ruler body 1, which has a connecting groove 15 inside, also has an inner mounting recess 20 at the same height as the side connecting opening. The fixing plate 18 is fixedly connected to two threaded rods 21 on the outer surface of the inner mounting recess 20. The ends of the two threaded rods 21 are flush with the outer surface of the measuring ruler body 1. The handle 19 has a mounting hole 22 corresponding to the threaded rod 21. The threaded rod 21 passes through the mounting hole 22 and is threaded with a mating nut 23 on its outwardly extending outer surface.

[0024] The purpose of this solution is to: mount the handle 19 onto the two threaded rods 21 on the outer surface of the fixing plate 18 through the mounting hole 22, with the ends of the threaded rods 21 flush with the outer surface of the measuring scale body 1; tighten the mating nut 23 to fix the handle 19; fix the fixing plate 18 to the contact block 17 and pass through the side connection port of the measuring scale body 1; the handle 19 can push the contact block 17 to slide along the guide rod 16 in the connection groove 15, so that the contact block 17 passes through the upper connection port and fits tightly against the plane to be measured, ensuring the fit between the measuring scale body 1 and the plane; when disassembling, loosen the mating nut 23 to remove the handle 19, avoiding interference with the measurement operation or scratching the plane due to the protruding structure; The recessed notch 20 makes the handle 19 flush with the surface of the measuring ruler body 1, ensuring that the measuring ruler makes flat contact with the plane during measurement. At the same time, the detachable design improves the convenience of storage and indirectly ensures the smoothness and accuracy of the angle measurement.

[0025] like Figure 1 and Figure 6As shown, the angle disc 7 is located between the adjusting bar 3 and the positioning nut 6, and three positioning posts 24 are fixedly connected to the outer surface of the measuring ruler body 1 on which the angle disc 7 is provided. The angle disc 7 has three positioning holes 25 corresponding to the positioning posts 24, and the angle disc 7 is sleeved on the positioning posts 24 through the three positioning holes 25.

[0026] The purpose of this solution is as follows: During installation, the angle disk 7 is positioned between the adjusting strip 3 and the positioning nut 6. The three positioning holes 25 on the angle disk 7 are aligned with the three positioning posts 24 on the outer surface of the measuring scale body 1, thereby achieving precise positioning and fixation of the angle disk 7. This prevents the angle disk 7 from rotating or shifting during the measurement process, ensuring that the degree scale line 8 on the outer surface of the angle disk 7 and the angle pointer 9 on the other adjusting strip 3 are always accurately positioned. This structure ensures the consistency of the angle reading, avoids reading errors caused by disk displacement, and makes the measurement results of the angle between the two planes more accurate, meeting the requirements of high-precision measurement.

[0027] like Figure 3 and Figure 5 As shown, straight scale grooves 26 are provided on the outer surfaces of the two measuring scale bodies 1. On the lower surfaces of the two measuring scale bodies 1, and near the openings of the adjustment grooves, symmetrically arranged L-shaped mounting blocks 27 are fixedly connected. On the parallel outer surfaces of the two L-shaped mounting blocks 27, there are equal-sized and coaxially arranged fixing holes 28.

[0028] Further explanation of this solution: First, by setting the linear scale groove 26, the function of the measuring ruler body 1 can be further enhanced, and the measurement of the length of the relevant construction section can be further realized through the linear scale groove 26; Meanwhile, the purpose of setting the L-shaped mounting block 27 and fixing hole is that after completing the plane angle measurement, the two measuring ruler bodies 1 are pulled closer to each other, and finally the two L-shaped mounting blocks 27 are attached. By inserting bolts between the two fixing holes 28 and screwing on nuts, the fixing between the two measuring ruler bodies can be completed, further increasing the overall measuring length of the measuring ruler body 1.

[0029] like Figure 1 and Figure 3 As shown, one of the measuring ruler bodies 1 has a linear scale groove 26 and an installation groove 29 is also provided on its outer surface. A bubble level 30 is fixedly connected inside the installation groove 29.

[0030] Further explanation of this solution: The operator holds the measuring ruler body 1 and aligns it with the plane to be measured. Through the bubble level 30 in the mounting slot 29, the horizontal state of the plane to be measured can be accurately detected, further improving the measurement range and function of this measuring device, and greatly enhancing the applicability and functionality of this device.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
