Description

Technical Field

[0001] The present application relates to the technical field of measuring rulers, and in particular to a measuring ruler for engineering supervision. Background Art

[0002] The measuring ruler used for project supervision is a kind of inspection tool. The ruler is classified into student ruler, vertical inspection ruler, diameter measuring ruler and project quality detector. It can detect whether the wall and tiles are flat and vertical. It can also detect whether the floor keel is horizontal and flat.

[0003] Among them, the project quality detector (2-meter ruler) is mainly used for the vertical level and any flatness detection of wall, door and window frame decoration veneer and other projects. It is made of 2-meter folding aluminum alloy, and the instrument is a mechanical pointer type. In the existing technology, when testing the flatness of the beam, the side of the ruler is pressed obliquely on the beam and the wall to observe the instrument to judge the flatness of the beam.

[0004] However, in the prior art, the side of the ruler is pressed obliquely against the beams and walls, and the construction workers hold it with their hands to stick it on. When the number of beams to be measured is small, they will not feel tired. However, in a large construction site, when multiple beams need to be measured, the construction workers need to hold the ruler with both hands and press the side of the ruler obliquely against the beams and walls every time they measure. This increases the number of measurements made by the construction workers, which makes them tired, thereby reducing the measurement efficiency. In order to improve the measurement efficiency of the construction workers, a measuring ruler for engineering supervision is needed. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this application is to provide a measuring ruler for engineering supervision to solve the technical problem in the prior art that construction workers need to hold the ruler and press the side of the ruler obliquely against beams and walls every time they measure, which reduces the measurement efficiency after multiple measurements.

[0006] The above-mentioned purpose of the present application is achieved through the following technical solutions: a measuring ruler for engineering supervision, including a ruler body and a supporting device, the supporting device including two opposite fixed plates, a connecting plate and a supporting plate, the two fixed plates are fixedly connected to the back of the ruler body with a gap between them, one end of the connecting plate is located between the two fixed plates and is rotatably connected to the fixed plates, the interior of the connecting plate is hollow and an opening is provided at one end away from the fixed plates, racks are provided on both sides of the connecting plate, racks for connecting to the racks inside the connecting plate are provided on both sides of the supporting plate, and the support plate is plugged into the connecting plate.

[0007] By adopting the above technical solution, when construction workers need to measure the flatness of the beam, they only need to pull the support plate out of the connecting plate, then rotate the connecting plate so that the ruler and the support plate form an acute angle, place the end of the support plate away from the fixed plate against the ground, and then place the side of the ruler against the wall and the beam. In this way, when construction workers measure the flatness of the beam, they only need to slightly press the ruler with one hand to measure the beam, which greatly saves the force required by construction workers to measure the beam, thereby achieving the purpose of improving the measurement efficiency of construction workers.

[0008] Furthermore, a plug-in slot penetrating the connecting plate is provided on one side of the connecting plate away from one end of the fixing plate, and a baffle is plugged into the plug-in slot of the connecting plate.

[0009] By adopting the above technical solution, the construction workers need to store and transfer the ruler after completing the measurement. Although the setting of the rack prevents the support plate from easily sliding out of the connecting plate, the vibration generated during the transfer process may cause the support plate to slide out of the connecting plate due to vibration. The setting of the baffle solves this technical problem. When the construction workers need to store and transfer the ruler after completing the measurement, they first push the support plate to be inserted into the connecting plate, and then push the baffle to block the opening of the connecting plate to seal the support plate in the connecting plate. In this way, the vibration generated when the construction workers store and transfer the ruler after completing the measurement will not cause the support plate to slide out of the connecting plate due to vibration.

[0010] Furthermore, a pull ring is provided at one end of the baffle away from the plug-in slot, and the pull ring is fixedly connected to the baffle.

[0011] By adopting the above technical solution, the setting of the pull ring can more conveniently push the baffle to plug into the connecting plate.

[0012] Furthermore, a friction block rotatably connected to the support plate is provided at one end of the support plate away from the connecting plate, and a friction surface is provided at one side of the friction block away from the support plate.

[0013] By adopting the above technical solution, although the setting of the support plate can help construction workers save effort and improve measurement efficiency, the end face of the support plate away from the connecting plate is usually not completely in contact with the ground when supported on the ground, which sometimes causes the support plate to slide and become unstable. The setting of the friction block solves this technical problem. The rotatable friction block can fully contact the ground at any angle, thereby enhancing the friction between the support plate and the ground and reducing the occurrence of unstable support rod placement.

[0014] Furthermore, a placement groove having a shape matching that of the connecting plate is provided at the lower end of one side of the ruler body connected to the fixing plate.

[0015] By adopting the above technical solution, the ruler used for engineering measurement can usually be folded for use. However, in the present invention, the ruler cannot be completely folded due to the setting of the supporting device. The setting of the placement groove solves this technical problem. When the ruler needs to be folded, the supporting plate can be first stored in the connecting plate, and then the folding ruler can be rotated. At this time, the connecting plate will be embedded in the placement groove, so that the ruler can be completely folded, thereby achieving the purpose of improving the user experience.

[0016] Furthermore, a rotating rib is provided on one side of the connecting plate close to the ruler body, one end of the rotating rib is rotatably connected to the connecting plate, and the other end is rotatably connected to the ruler body, and a rotating portion is provided in the middle of the rotating rib.

[0017] By adopting the above technical solution, although the setting of the friction block improves the placement stability of the support rod, it also causes one end of the support rod supporting the ground to rotate. If the construction workers are not careful, it is easy for the ruler to slide and be unstable. The setting of the rotating ribs solves this technical problem. When the rotating ribs are turned on the connecting plate to make the ruler and the support plate form an acute angle, they will become a straight rod, which can provide a restricted placement for the ruler, and the ruler will slide and be unstable. The rotating ribs can also increase the strength and rigidity of the connection between the connecting plate and the ruler.

[0018] Furthermore, a receiving groove is provided at one end of the ruler body connected to the rotating rib, and one end of the rotating rib rotatably connected to the ruler body is located in the receiving groove.

[0019] By adopting the above technical solution, although the setting of the rotating ribs enhances the stability of the placement of the ruler, the setting of the rotating ribs causes the connecting plate to not completely fit the ruler, which results in the connecting plate not being able to be completely embedded in the placement groove when the ruler is folded. The setting of the storage groove solves this technical problem. When the connecting plate is rotated to approach the ruler, the rotating ribs will be folded and stored in the storage groove, so that the connecting plate can be completely fitted with the ruler, which will not affect the folding of the ruler and improve the user experience.

[0020] Furthermore, the connecting plate is a plate made of light steel.

[0021] By adopting the above technical solution, the light steel is light in weight and can save the effort of construction workers.

[0022] In summary, the present application includes at least one of the following beneficial technical effects.

[0023] 1. Through the arrangement of the ruler body and the supporting device, when construction workers need to measure the flatness of the beam, they only need to pull the supporting plate out of the connecting plate, and then rotate the connecting plate to make the ruler and the supporting plate form an acute angle, place the end of the supporting plate away from the fixed plate against the ground, and then place the side of the ruler against the wall and the beam. In this way, when construction workers measure the flatness of the beam, they only need to slightly press the ruler with one hand to measure the beam, which greatly saves the force required by construction workers to measure the beam, thereby improving the measurement efficiency of construction workers.

[0024] 2. Through the setting of the baffle, it is possible to push the support plate into the connecting plate, and then hold the pull ring to push the baffle to block the opening of the connecting plate, so that the support plate is closed in the connecting plate. In this way, when the construction workers complete the measurement and transfer the ruler, the vibration generated will not cause the support plate to slide out of the connecting plate, thereby improving the user experience.

[0025] 3. Through the setting of the storage groove and the placement groove, the connecting plate can be rotated close to the ruler, and the rotating ribs will be folded and stored in the storage groove, so that the connecting plate can completely fit the ruler without affecting the folding of the ruler. Then the support plate is stored in the connecting plate, the pull ring is held and the baffle is pushed to block the opening of the connecting plate, and then the folding ruler is rotated. At this time, the connecting plate will be embedded in the placement groove, so that the ruler can be completely folded and stored, which is convenient for transportation.

[0030] The present application is further described in detail below with reference to the accompanying drawings.

[0031] Example, see Figure 1 , Figure 2The project supervision measuring ruler comprises a ruler body 1 and a supporting device 2, wherein the supporting device 2 comprises two opposite fixing plates 20, a connecting plate 21 and a supporting plate 22, wherein the two fixing plates 20 are fixedly connected to the back of the ruler body 1 with a gap therebetween, one end of the connecting plate 21 is located between the two fixing plates 20 and is rotatably connected to the fixing plates 20, the connecting plate 21 is hollow inside and an opening is provided at one end away from the fixing plates 20, racks 23 are provided on both sides of the connecting plate 21, racks 23 connected to the racks 23 inside the connecting plate 21 are provided on both sides of the supporting plate 22, and the supporting plate 22 comprises a connecting plate 21 and a connecting plate 22. The support plate 22 is plugged into the connecting plate 21. When the construction workers need to measure the flatness of the beam, they only need to pull the support plate 22 out of the connecting plate 21, and then rotate the connecting plate 21 so that the ruler and the support plate 22 form an acute angle, and place the end of the support plate 22 away from the fixed plate 20 against the ground, and then place the side of the ruler against the wall and the beam. In this way, when the construction workers measure the flatness of the beam, they only need to press the ruler slightly with one hand to measure the beam, which greatly saves the force needed by the construction workers to measure the beam, thereby achieving the purpose of improving the measurement efficiency of the construction workers.

[0032] After the construction workers have completed the measurement, they need to store and transfer the ruler. Although the setting of the rack 23 prevents the support plate 22 from easily sliding out of the connecting plate 21, the vibration generated during the transfer process may cause the support plate 22 to be vibrated and slide out of the connecting plate 21. In order to solve this technical problem, in this embodiment, a plug-in groove 24 that passes through the connecting plate 21 is opened on one side of the connecting plate 21 away from the end of the fixed plate 20, and a baffle 3 is inserted at the plug-in groove 24 of the connecting plate 21. The end of the baffle 3 away from the plug-in groove 24 is provided with a pull ring 30 fixedly connected to the baffle 3. When the construction workers need to store and transfer the ruler after the measurement is completed, they first push the support plate 22 to be inserted into the connecting plate 21, and then hold the pull ring 30 to push the baffle 3 to block the opening of the connecting plate 21, so as to close the support plate 22 in the connecting plate 21. In this way, the vibration generated when the construction workers store and transfer the ruler after the measurement is completed will not cause the support plate 22 to be vibrated and slide out of the connecting plate 21.

[0033] Although the setting of the support plate 22 can help construction workers save effort and improve measurement efficiency, the end surface of the support plate 22 away from the connecting plate 21 is usually not completely in contact with the ground when supported on the ground, which sometimes causes the support plate 22 to slide and become unstable. In order to solve this technical problem, refer to Figure 3 In this embodiment, a friction block 4 rotatably connected to the support plate 22 is provided at one end of the support plate 22 away from the connecting plate 21, and a friction surface is provided on a side of the friction block 4 away from the support plate 22. The rotatably arranged friction block 4 can fully contact the ground at any angle, thereby enhancing the friction between the support plate 22 and the ground and reducing the occurrence of unstable placement of the support rod.

[0034] Although the setting of the friction block 4 improves the placement stability of the support rod, it also causes one end of the support rod supporting the ground to rotate. If the construction workers are not careful, it is easy for the ruler to slide and be unstable. In order to solve this technical problem, in this embodiment, a rotating rib 5 is provided on one side of the connecting plate 21 close to the ruler body 1. One end of the rotating rib 5 is rotatably connected to the connecting plate 21, and the other end is rotatably connected to the ruler body 1. A rotating part is provided in the middle of the rotating rib 5. When the connecting plate 21 is rotated to make the ruler and the support plate 22 form an acute angle, the rotating rib 5 will become a straight rod, thereby providing a restricted placement for the ruler, and the ruler will slide and be unstable. In addition, the rotating rib 5 can also increase the strength and rigidity of the connection between the connecting plate 21 and the ruler.

[0035] A ruler used for engineering measurement can usually be folded for use, but in this embodiment, the ruler cannot be completely folded due to the setting of the supporting device 2. In order to solve this technical problem, in this embodiment, a placement groove 10 with a shape matching the shape of the connecting plate 21 is provided at the lower end of one side of the ruler body 1 connected to the fixing plate 20, and a storage groove 11 is provided at one end of the ruler body 1 connected to the rotating rib 5, and the end of the rotating rib 5 that is rotatably connected to the ruler body 1 is located in the storage groove 11. First, when the connecting plate 21 is rotated close to the ruler, the rotating rib 5 will be folded and stored in the storage groove 11, so that the connecting plate 21 can be completely fitted with the ruler, so that the folding of the ruler will not be affected, and then the support plate 22 is stored in the connecting plate 21, and then the folded ruler is rotated. At this time, the connecting plate 21 will be embedded in the placement groove 10, so that the ruler can be completely folded, thereby achieving the purpose of improving the user experience.

[0036] Specific implementation process: When it is necessary to use a ruler to measure the flatness of the beam, pull the support plate 22 out of the connecting plate 21, then rotate the connecting plate 21 so that the ruler and the support plate 22 form an acute angle, place the friction block 4 against the ground, and then place the side of the ruler against the wall and the beam. In this way, when the construction workers measure the flatness of the beam, they only need to press the ruler slightly with one hand to measure the beam.

[0037] When the ruler needs to be stored after the measurement is completed, first rotate the connecting plate 21 close to the ruler, and the rotating rib 5 will be folded and stored in the storage groove 11, so that the connecting plate 21 can completely fit the ruler without affecting the folding of the ruler, and then store the support plate 22 into the connecting plate 21, hold the pull ring 30 and push the baffle 3 to block the opening of the connecting plate 21, and then rotate the folding ruler. At this time, the connecting plate 21 will be embedded in the placement groove 10, so that the ruler can be completely folded and stored.

[0038] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
