Technical Field

[0001] This application relates to the field of verticality testing instruments, and in particular to a portable laser testing rod for building verticality. Background Technology

[0002] Building construction (referred to as "building construction") refers to the engineering work that forms an internal space with structural elements such as roof, beams, columns, walls, and foundations to meet the needs of production, living, and public activities. Verticality, as a directional tolerance, controls the parallelism between the measured element (such as a wall) and the reference element (usually the direction of gravity).

[0003] Existing verticality measuring instruments have a fixed length. In actual testing, when measuring the verticality of large walls, it is necessary to measure in sections, which increases the risk of error. If a job requires testing walls of different sizes, multiple verticality measuring instruments of different models need to be carried.

[0004] Existing verticality measuring instruments are not compatible with measuring the verticality of walls of different sizes; and when the testing site is far away, large-sized measuring instruments are also inconvenient to carry. Utility Model Content

[0024] The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] Please see Figures 1-5 This application provides a portable laser inspection rod for building verticality, which improves the compatibility of verticality inspection instruments with walls of different sizes.

[0026] In this embodiment, refer to Figures 1-5 The portable building verticality laser testing rod includes a housing cylinder 1, a mounting box 2, an extension component, a locking component 4, and a testing component 5. Two housing cylinders 1 are symmetrically arranged, with clearance holes 11 at opposite ends of each cylinder. The mounting box 2 is located at one end of the housing cylinder 1 and is coaxially aligned with it. One end of the extension component is connected to the end of the mounting box 2 near the housing cylinder 1, and the other end extends into the housing cylinder 1, with the extension component slidably connected to the housing cylinder 1. The locking component 4 is mounted on the housing cylinder 1 and connected to the extension component. The testing component 5 is mounted on the mounting box 2.

[0027] Specifically, by moving the extension component from inside the housing 1 to one end of the mounting box 2, the mounting box 2 is moved to a suitable position. Then, the position of the extension component is fixed by the locking component 4, which improves the compatibility of the verticality detector for walls of different sizes. Subsequently, the mounting box 2 is unfolded, and the verticality of the wall is tested using the testing component 5. The testing component 5 can be adjusted to the optimal position by the extension rod 32 according to the actual size of the wall, avoiding segmented testing and ensuring the accuracy of the test results.

[0028] See Figure 1 and Figure 2 The locking component 4 includes: a slide groove 41, a rack 42, a slider 43, and a locking tooth 44. The slide groove 41 is opened through one side of the receiving cylinder 1, and the length of the slide groove 41 is less than the length of the receiving cylinder 1. The rack 42 is arranged along the length of the slide groove 41 on one side of the slide groove 41. The slider 43 is mounted on the extension assembly, extends out of the slide groove 41, and can slide along the slide groove 41. The locking tooth 44 is rotatably connected to one end of the slider 43 that extends out of the slide groove 41. The teeth of the locking tooth 44 can mesh with the rack 42, and the connection between the locking tooth 44 and the slider 43 is provided with damping.

[0029] Specifically, when adjusting the position of the detection component 5, the slider 43 slides along the slide groove 41, and the extension component extends outward from the clearance hole 11 by a suitable distance through the slider 43. After the extension distance is determined, the locking tooth 44 is rotated to engage the teeth on the locking tooth 44 with the rack 42, ensuring that the extension rod 32 can be firmly fixed on the rack 42 through the locking tooth 44 during the perpendicularity detection process. The position where the locking tooth 44 and the slider 43 are rotatably connected is provided with damping, which ensures that the engagement state of the locking tooth 44 and the rack 42 remains stable during the process of fixing the position of the extension component.

[0030] See Figure 2 and Figure 5 The extension assembly includes: an extension rod 32, a blocking block 31, and a return spring 33. One end of the extension rod 32 is located at the end of the mounting box 2 near the receiving cylinder 1, and the other end extends into the receiving cylinder 1 and is slidably connected to the receiving cylinder 1. The blocking block 31 is located inside the receiving cylinder 1 and is connected to the end of the extension rod 32 that extends into the receiving cylinder 1. A slider 43 is mounted on the blocking block 31. The return spring 33 is sleeved on the extension rod 32 and has a cross-sectional area smaller than that of the blocking block 31.

[0031] Specifically, when the extension rod 32 slides outward toward the clearance hole 11, the blocking block 31 presses against the return spring 33. Subsequently, the position of the extension rod 32 is fixed by the engagement of the locking teeth 44 and the rack 42. The damping setting further counteracts the elastic tension of the return spring 33, ensuring the stability of the extension rod 32 and the stability of the test piece 5 during the test. After the test is completed, the locking teeth 44 are rotated to disengage the engagement between the locking teeth 44 and the rack 42. At this time, the return spring 33 pushes against the blocking block 31, thereby enabling the extension rod 32 to drive the mounting box 2 to quickly return to its original position. The cross-sectional area of ​​the return spring 33 is greater than the area of ​​the clearance hole 11, ensuring that the return spring 33 will not be squeezed out of the clearance hole 11 when it is pressed. At the same time, the cross-sectional area of ​​the return spring 33 is smaller than the area of ​​the blocking block 31, further ensuring that the return spring 33 will not fall off the blocking block 31, effectively improving the stability of the return spring 33 in achieving rapid rebound and return.

[0032] See Figure 1 The installation box 2 includes: a box body 21, a cover plate 22, and a connector 23. The box body 21 forms a storage cavity inside, one end of which is connected to the extension component, and the other end is open. The cover plate 22 is disposed on the box body 21 and is located on the side of the box body 21 that is perpendicular to the length direction of the slide groove 41. The cover plate 22 can be flipped and connected to the box body 21. The connector 23 is installed in the storage cavity and is rotatably connected to the cover plate 22, providing the driving force for the cover plate 22 to flip.

[0033] Specifically, the cover plate 22 is opened and flipped along the end of the box body 21 away from the extension rod 32. The open design of the cover plate 22 serves to avoid obstacles when it flips. The detection element 5 is installed on the cover plate 22. When the verticality is detected, the connecting piece 23 drives the cover plate 22 to flip along the box body 21. Then the detection element 5 starts to detect the verticality. The cover plate 22 can be flipped and stored in the storage cavity. When no detection work is being carried out, the cover plate 22 can provide protection for the detection element 5.

[0034] See Figure 5 The connector 23 includes: a track plate 231, a sliding rod 232, a support rod 233, a rotating shaft 234, and a fixing buckle 235. Two track plates 231 are symmetrically arranged within the storage cavity along the extension direction of the extension rod 32, and symmetrical adjustment grooves are provided on the two track plates 231. The sliding rod 232 is vertically arranged within the adjustment groove, with both ends extending out of the two adjustment grooves respectively. Two support rods 233 are symmetrically rotatably connected to the two ends of the sliding rod 232 at the same end. The rotating shaft 234 is arranged parallel to the sliding rod 232 on the cover plate 22, and both ends of the rotating shaft 234 are rotatably connected to the support rod 233 on the same side respectively. The fixing buckle 235 is rotatably connected between the two track plates 231 and detachably connected to the sliding rod 232. When the fixing buckle 235 is connected to the sliding rod 232, the cover plate 22 is perpendicular to the mounting box 2.

[0035] Specifically, when the cover plate 22 is flipped, the sliding rod 232 is driven to slide along the adjustment groove toward the open end of the box body 21. The sliding rod 232 drives one end of the support rod 233 to move upward, and the other end of the support rod 233 is rotatably connected to the cover plate 22. The end of the cover plate 22 is rotatably connected to the open end of the box body 21. Thus, when the sliding rod 232 is slid toward the open end, the support rod 233 will drive the cover plate 22 to flip. When the sliding rod 232 slides to the point where the cover plate 22 is perpendicular to the box body 21, the flipping fixing buckle 235 fixes the sliding rod 232, thereby ensuring that the cover plate 22 remains perpendicular to the box body 21 throughout the perpendicularity detection process, thus improving the accuracy of the detection results.

[0036] See Figures 3-5 The detection component 5 includes: a laser lamp 51, an observation ruler 52, and a detection block 53. The laser lamp 51 is suspended by a chain on the side of the cover plate 22 opposite to the storage cavity, and the irradiation path of the laser lamp 51 is always consistent with the direction of gravity. The observation ruler 52 is located on the side of the cover plate 22 away from the laser lamp 51, on the side of the cover plate 22 opposite to the connected component 23. The detection block 53 is located at the end of the cover plate 22 away from the flip axis.

[0037] Specifically, after the position of the mounting box 2 is adjusted appropriately, the connecting piece 23 drives the cover plate 22 to flip to a position perpendicular to the box body 21, and then the wall surface is inspected. First, the laser light 51 is turned on to illuminate the observation ruler 52, ensuring that the light from the laser light 51 coincides with the verticality standard point on the observation ruler 52. Then, the detection blocks 53 at both ends are placed against the wall to be tested, and then the position on the observation ruler 52 is observed to see if there is any deviation. If the light from the laser light 51 deviates, it indicates that there is an error in the test wall verticality, and the observation results can be clearly and accurately represented.

[0038] See Figure 5 The mounting box 2 is located on one side of the cover plate 22, near the end of the receiving cylinder 1, and has a snap-fit ​​groove 24 that is fixed to the detection block 53.

[0039] Specifically, the snap-fit ​​groove 24 is used to snap the detection block 53 into the snap-fit ​​groove 24 during storage, ensuring that the cover plate 22 will not open during the transfer process after storage, further improving the protection effect of the detection piece 5.

[0040] See Figure 1 and Figure 5 The closed end of the container 1 is provided with a buffer pad 14, and the outside of the container 1 is provided with a handle 13.

[0041] Specifically, the buffer pad 14 effectively reduces the rigid contact damage to the receiving cylinder 1 caused by the extension rod 32 when it is quickly reset by the reset spring 33, and extends the service life of the detection block 53. The handle 13 provides great convenience for operators during use and transportation.
