Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering measuring tools, in particular to a multifunctional measuring tool for construction project acceptance. Background Technique

[0002] Buildings are the general term for buildings and structures, and measuring tools are the general term for various measuring tools. Measuring tools are widely used in industries such as construction. Bricks, steel bars and other supplies used in construction all need to be measured.

[0003] Chinese Patent Publication No. CN215930737U discloses a multifunctional building detection measuring tool, including a measuring tool frame. A first measuring plate is arranged inside the measuring tool frame, and a slot is arranged inside the measuring tool frame. Both sides of one end of the first measuring plate are fixedly connected with rotating shafts, and the other ends of the rotating shafts are rotatably connected with the measuring tool frame. The measuring tool frame is rotatably connected inside the measuring tool frame through the rotating shafts, and there is a certain damping between the rotating shafts and the measuring tool frame. By accommodating the linear measurement tool in a measuring tool frame, the measuring tool becomes delicate and convenient to carry, and the length of the measuring tool can be extended according to actual measurement needs. By setting an angle meter on the measuring tool frame, and through the cooperation of the pointer connected to the first measuring plate and the circular instrument scale in the angle meter, the included angle between objects can be measured.

[0004] After the above-mentioned patent unfolds the first side plate and the second side plate, it is difficult to make the measuring tool fit the surface of the object to be measured. Therefore, when observing the data of the object to be measured, large errors are likely to occur due to the inclination of the line of sight, and inaccurate measurement data is likely to occur. Content of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a multifunctional measuring tool for construction project acceptance, so as to solve the technical problems mentioned in the above background technique.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions:

[0007] A multifunctional measuring tool for construction project acceptance, including two triangular plates and two measuring strips. The two triangular plates are connected to each other through a connecting structure. The triangular plate has a right angle. A rotating shaft is arranged in the middle of the inclined surface of the triangular plate, and a quick-release structure is arranged inside the rotating shaft;

[0008] The shape of the measuring strip is trapezoidal, and quick-release holes are arranged on both inclined side walls of the measuring strip. The measuring strip and the triangular plate are rotatably connected through the rotating shaft and the quick-release holes, and the inclined side wall of the measuring strip is aligned with the inclined surface of the triangular plate;

[0009] A telescopic groove is arranged at the top of the measuring strip, and an angle measuring structure is arranged inside the telescopic groove.

[0010] Further, the quick-release structure includes mounting holes. There are four mounting holes, which are arranged in a circumferential array on the circumferential side of the rotating shaft. A support spring is provided at the inner bottom end of the mounting hole, and a locking steel ball is provided at the top end of the support spring. When the support spring is in its original state, the locking steel ball protrudes from the mounting hole.

[0011] Further, the quick-release hole is opened in the middle of the inclined side wall of the measuring strip. The depth of the quick-release hole is equal to the length of the rotating shaft, and a locking groove is opened at a position on the hole wall of the quick-release hole corresponding to the locking steel ball.

[0012] Further, the angle measuring structure includes a rotating disk. The rotating disk is installed at one end inside the telescopic groove, and a measuring plate parallel to the upper end surface of the measuring strip is provided on the circumferential side of the rotating disk. Measuring scales are provided on the disk surface of the rotating disk.

[0013] Further, a locking sliding groove is opened at the bottom end of the triangular plate. A locking slider is slidably provided inside the locking sliding groove. A positioning sliding groove is provided at a position on the bottom end of the measuring strip corresponding to the locking sliding groove. Magnets that attract each other are provided between the inside of the positioning sliding groove and the end of the locking slider.

[0014] Further, the connecting structure includes a plug rod and a plug tube. The plug tube and the plug rod are respectively connected to one right-angled side corresponding to the two triangular plates.

[0015] In summary, the present utility model includes at least one of the following beneficial technical effects:

[0016] 1. For this multifunctional measuring tool for building engineering acceptance, two measuring strips are respectively installed on both sides of the triangular plate. There are scales on the side edges of the measuring strips, and the distance between the two measuring strips is equal to one unit of the scale of the measuring strip, and the scales are flush with each other. Furthermore, when measuring the length of a building project, the two measuring strips can be simultaneously leaned against the side wall of the object to be measured, and the distance between the side walls of the object to be measured can be observed to achieve the purpose of measuring length data. And because the measuring strip is rotatably connected to the triangular plate, after the two measuring strips are rotated 180 degrees, the two measuring strips are in contact with each other, achieving the purpose of facilitating the storage of the measuring device. And after unfolding, the scales of the two measuring strips are in the same plane, which can effectively achieve the purpose of facilitating measurement;

[0017] 2. When connecting the triangular plate and the measuring bar of the multifunctional measuring tool for building engineering acceptance, the rotating shaft is directly inserted into the internal of the quick-release hole. Since the aperture of the quick-release hole is equal to the shaft diameter of the rotating shaft, when the rotating shaft is inserted into the quick-release hole, the hole wall of the quick-release hole will push the locking steel ball into the installation hole and compress the support spring. After the rotating shaft is completely inserted into the quick-release hole, the locking steel ball pops out, thereby clamping the rotating shaft into the quick-release hole and achieving the purpose of connecting the measuring bar and the triangular plate.

Detailed Description of the Embodiments

[0026] The following will further elaborate on the present invention in conjunction with the drawings.

[0027] Embodiment:

[0028] Refer to Figure 1 - Figure 6 , a multifunctional measuring tool for building engineering acceptance disclosed by the present utility model, includes two triangular plates 1 and two measuring strips 2. The two triangular plates 1 are interconnected through a connecting structure 3. The triangular plate 1 has a right angle. A rotating shaft 4 is arranged in the middle of the inclined surface of the triangular plate 1, and a quick-release structure 5 is arranged inside the rotating shaft 4;

[0029] The shape of the measuring strip 2 is trapezoidal, and quick-release holes 6 are opened on both inclined side walls of the measuring strip 2. The measuring strip 2 and the triangular plate 1 are rotationally connected through the rotating shaft 4 and the quick-release holes 6, and the inclined side wall of the measuring strip 2 is aligned with the inclined surface of the triangular plate 1;

[0030] A telescopic groove 7 is opened at the top of the measuring strip 2, and an angle measuring structure 8 is arranged inside the telescopic groove 7.

[0031] In this embodiment, as Figure 1 shown, the two triangular plates 1 are interconnected. The two triangular plates 1 are completely the same, and the two angles except the right angle are both 45 degrees. The two measuring strips 2 are respectively installed on both sides of the triangular plate 1. A scale is arranged on the side of the measuring strip 2, and the distance between the two measuring strips 2 is equal to one unit of the scale of the measuring strip 2, and the scales are mutually flush. Then, when measuring the length of a building project, the two measuring strips 2 can be simultaneously leaned against the side wall of the object to be measured, and the distance between the side walls of the object to be measured can be observed to achieve the purpose of measuring the length data;

[0032] Since the measuring strip 2 and the triangular plate 1 are rotationally connected through the rotating shaft 4 and the quick-release holes 6, the measuring strip 2 can be rotated 180 degrees along the rotating shaft 4 to form a right angle between the two measuring strips 2. At this time, the two measuring strips 2 are respectively leaned against the side walls of the corner, and the angle measuring structure 8 is pulled out, as Figure 5 and Figure 6 shown. At this time, the purpose of measuring the angle between two walls can be achieved;

[0033] Through the setting of the quick-release structure 5 and the quick-release holes 6, the triangular plate 1 and the measuring strip 2 can be quickly interconnected or disassembled, and then the length of the device can be extended to improve the measuring range.

[0034] In a further preferred embodiment of the present utility model, as Figures 1-6As shown, the quick-release structure 5 includes a mounting hole 51. Four mounting holes 51 are provided and are arranged in a circumferential array on the circumferential side of the rotating shaft 4. A support spring 52 is provided at the inner bottom end of the mounting hole 51. A locking steel ball 53 is provided at the top end of the support spring 52. When the support spring 52 is in its original state, the locking steel ball 53 protrudes from the mounting hole 51.

[0035] In this embodiment, the support spring 52 is positioned and installed through the mounting hole 51, and the locking steel ball 53 is pushed to a state where it protrudes from the mounting hole 51 by the arrangement of the support spring 52. When connecting the triangular plate 1 and the measuring strip 2, the rotating shaft 4 is directly inserted into the quick-release hole 6. Since the aperture of the quick-release hole 6 is equal to the shaft diameter of the rotating shaft 4, when the rotating shaft 4 is inserted into the quick-release hole 6, the hole wall of the quick-release hole 6 will push the locking steel ball 53 into the mounting hole 51 and compress the support spring 52. After the rotating shaft 4 is completely inserted into the quick-release hole 6, the locking steel ball 53 pops out again, thereby achieving the purpose of clamping the rotating shaft 4 into the quick-release hole 6 and connecting the measuring strip 2 and the triangular plate 1.

[0036] In a further preferred embodiment of the present utility model, as Figures 1-6 shown, the quick-release hole 6 is opened in the middle of the inclined side wall of the measuring strip 2. The hole depth of the quick-release hole 6 is equal to the length of the rotating shaft 4. A locking groove 61 is opened at a position corresponding to the locking steel ball 53 on the hole wall of the quick-release hole 6.

[0037] In this embodiment, after the rotating shaft 4 is completely inserted into the quick-release hole 6, the locking steel ball 53 protrudes from the mounting hole 51 under the thrust of the support spring 52 and engages with the locking groove 61, thereby achieving the purpose of clamping the rotating shaft 4 into the quick-release hole 6 and connecting the measuring strip 2 and the triangular plate 1.

[0038] In a further preferred embodiment of the present utility model, as Figures 1-6 shown, the angle measuring structure 8 includes a rotating disk 81. The rotating disk 81 is installed at one end inside the telescopic groove 7, and a measuring plate 82 parallel to the upper end surface of the measuring strip 2 is provided on the circumferential side of the rotating disk 81. Measuring scales are provided on the disk surface of the rotating disk 81.

[0039] In this embodiment, the measuring plate 82 can be rotated through the setting of the rotating disk 81. When measuring an angle, the measuring plate 82 is rotated out from the inside of the telescopic groove 7 with the rotating disk 81 as the axis, and one of the measuring strips 2 is rotated to be perpendicular to the other measuring strip 2. Then the two measuring strips 2 are respectively brought close to the corner to be measured to measure the angle of the corner. If the angle of the corner is equal to 90 degrees, the end walls of the two measuring strips 2 are respectively in contact with the two walls.

[0040] When the wall angle is less than 90 degrees, as Figure 5As shown, remove the measuring bar 2, connect the end of the measuring bar 2 away from the rotating disk 81 to the triangular plate 1, make the end without the angle measuring structure 8 contact the ground, and gradually move the measuring bar 2 closer to the wall until the arc surface at one end of the measuring bar 2 contacts the wall surface. At this time, rotate the measuring plate 82 to make it fit the wall surface. An angle A is formed between the measuring plate 82 and the measuring bar 2. Read the measurement scale on the disk surface of the rotating disk 81. At this time, the angle between the wall surface and the ground is equal to 90 degrees minus the degree of angle A;

[0041] When the angle of the wall is greater than 90 degrees, as Figure 6 shown, remove the measuring bar 2, connect the end of the measuring bar 2 with the rotating disk 81 to the triangular plate 1, make the end without the angle measuring structure 8 contact the ground, and gradually move the measuring bar 2 closer to the wall until one end of the measuring bar 2 contacts the wall surface. At this time, rotate the measuring plate 82 to make it fit the wall surface. An angle B is formed between the measuring plate 82 and the measuring bar 2. Read the measurement scale on the disk surface of the rotating disk 81. At this time, the angle between the wall surface and the bottom surface is equal to 90 degrees plus the degree of angle B.

[0042] In a further preferred embodiment of the present utility model, as Figures 1-6 shown, a locking chute 11 is provided at the bottom end of the triangular plate 1. A locking slider 12 is slidably arranged inside the locking chute 11. A positioning chute 21 is provided at the position corresponding to the locking chute 11 at the bottom end of the measuring bar 2. Magnets attracting each other are provided between the inside of the positioning chute 21 and the end of the locking slider 12.

[0043] In this embodiment, through the arrangement of the locking chute 11 and the locking slider 12, when the device detects the length, it is used to fix the triangular plate 1 and the measuring bar 2 to improve the stability of the device when measuring the length.

[0044] In a further preferred embodiment of the present utility model, as Figures 1-6 shown, the connecting structure 3 includes a plug rod 31 and a socket tube 32. The socket tube 32 and the plug rod 31 are respectively connected to a right-angled side corresponding to the two triangular plates 1.

[0045] In this embodiment, through the arrangement of the plug rod 31 and the socket tube 32, it is convenient to connect the two triangular plates 1 on both sides, so that the device can be extended in length to improve the detection range of the length.

[0046] The embodiments of this specific implementation manner are all preferred embodiments of the present utility model, and do not limit the protection scope of the present utility model accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present utility model should be covered within the protection scope of the present utility model.
