Description

Technical Field

[0001] This utility model relates to the field of wall surface inspection technology, and more specifically, to a wall surface flatness inspection device. Background Technology

[0002] In the existing field of wall flatness testing technology, the problem of adjusting the lateral position of the testing components seriously restricts the testing efficiency and accuracy. Traditional testing devices usually adopt a fixed installation structure or a simple sliding structure, and the lateral adjustment function is not perfect.

[0003] Most wall flatness testing devices lack a precise lateral fine-tuning mechanism. Adjustment mainly relies on operators manually moving the entire device based on experience, making it difficult to achieve millimeter-level precise positioning. During the testing process, in order to cover different areas of the entire wall, the position of the testing components usually needs to be adjusted multiple times. However, existing devices often use a bolt-fixed structure, requiring multiple bolts to be loosened and then tightened one by one after each adjustment, which is cumbersome and time-consuming.

[0004] Traditional testing devices often use a fixed connection structure, where the testing components are fixed to the main frame with multiple bolts. The installation and disassembly process requires the use of tools to operate each bolt one by one, which is time-consuming and labor-intensive. Some testing components are designed as an integrated structure, which cannot be replaced or adjusted according to different types of wall characteristics, greatly limiting the applicability and testing accuracy of the device.

[0030] Please see Figures 1-5A wall flatness testing device includes a testing component 1, a main frame 2, a translation adjustment mechanism, a testing locking mechanism, and a locking auxiliary mechanism. The translation adjustment mechanism includes a crossbeam 3, a scale plate 4, a movable sleeve 5, and a fixing bolt 6. The crossbeam 3 is horizontally mounted on the main frame 2, the scale plate 4 is fixedly mounted on the crossbeam 3, the movable sleeve 5 is horizontally slidable on the crossbeam 3 and the scale plate 4, and the fixing bolt 6 is mounted on the movable sleeve 5. The fixing bolt 6 can pass through the movable sleeve 5 to fix the movable sleeve 5 to the crossbeam 3. The testing locking mechanism includes... The device includes a locking tube 7, a locking rod 8, an inserting spring rod 9, a locking groove 10, an unlocking push ring 11, a movable spring rod 12, and an outer sliding sleeve 13. The locking rod 8 can extend into the locking tube 7. The inserting spring rod 9 is laterally slidably installed on the inner wall of the locking tube 7. The locking groove 10 is set on the side wall of the locking rod 8. The unlocking push ring 11 is directionally slidably installed on the inner wall of the locking tube 7. The movable spring rod 12 is longitudinally slidably installed on the side wall of the locking tube 7 and is connected to the unlocking push ring 11. The outer sliding sleeve 13 slides longitudinally on the outer wall of the locking tube 7.

[0031] In this embodiment, the precise positioning of the detection component 1 is achieved through a gear transmission system. After the operator loosens the fixing bolt 6, the rotating adjusting bolt 21 drives the rotating gear 23 to rotate on the gear plate 22, driving the moving sleeve 5 to slide smoothly on the crossbeam 3. The scale plate 4 provides a precise position reference. When the desired position is reached, the fixing bolt 6 is tightened, and the spring block 24 is in close contact with the crossbeam 3, firmly locking the position of the moving sleeve 5 and ensuring stable position during measurement. The locking rod 8 is inserted into the locking tube 7, and the extended spring rod 9 automatically embeds into the slot 10 on the side wall of the locking rod 8 to form a lock. At the same time, the side plate 20 and the mounting plate 401 are in close cooperation. During disassembly, the outer moving sleeve 13 is pushed up to drive the moving spring rod 12 and the unlocking push ring 11 to move up. The unlocking push ring 11 pushes the outer pry block 25 on the extended spring rod 9, causing the extended spring rod 9 to disengage from the slot 10, releasing the locking rod 8 and achieving rapid separation.

[0032] The locking auxiliary mechanism includes a rotating sleeve 14, a spiral plate 15, a spiral groove 16, ball blocks 17, counter-shrinking blocks 18, and counter-shrinking springs 19. The spiral sleeve is rotatably positioned on the outer wall of the locking tube 7. The spiral plate 15 is mounted on the spiral sleeve, and the spiral groove 16 is located on the outer sliding sleeve 13. The spiral plate 15 and the spiral groove 16 are slidably connected. The relative rotation of the spiral plate 15 and the spiral groove 16 causes the outer sliding sleeve 13 and the moving spring rod 12 to move longitudinally. Multiple sets of ball blocks 17 are arranged in a ring at the bottom end of the rotating sleeve 14, and multiple counter-shrinking blocks 18 are arranged in a ring on the outer wall of the locking tube 7. Each set of counter-shrinking blocks 18 consists of two opposing sets. The counter-shrinking springs 19 are installed between opposing counter-locking blocks. The ball blocks 17 extend through the opposing counter-shrinking blocks 18 step by step, so that the rotating sleeve 14 rotates stably on the outer wall of the locking tube 7.

[0033] In this embodiment, when the rotating sleeve 14 is rotated, the spiral plate 15 slides in the spiral groove 16, converting the rotational motion into the longitudinal movement of the outer sleeve 13. At the same time, the ball block 17 passes through the gaps between the shrinking blocks 18 step by step. The shrinking blocks 18 rhythmically contract and release under the action of the shrinking spring 19, providing clear tactile feedback to the operator and ensuring precise operation.

[0034] Please see Figure 1-5 As a supplementary embodiment of a wall flatness testing device for a translation adjustment mechanism, a detection locking mechanism, and a locking auxiliary mechanism: Side plates 20 are installed on both sides of the detection component 1, and the locking tube 7 is fixedly installed on the side plates 20. The locking rod 8 is fixedly installed on the mounting plate 401, and the locking tube 7 fits into the locking rod 8, so that the side plates 20 and the mounting plate 401 are connected. An adjusting bolt 21 is provided through the side of the movable sleeve 5, and the adjusting bolt 21 is set to rotate at the upper limit of the movable sleeve 5. The scale... A toothed plate 22 is installed on one side of plate 4, and a rotating tooth 23 is installed at one end of adjusting bolt 21. The rotating tooth 23 meshes with the toothed plate 22. The rotating tooth 23 rotates on the toothed plate 22 to move the moving sleeve 5 laterally. A compression spring block 24 is installed at one end of fixing bolt 6, and one end of compression spring block 24 is in contact with the outside of crossbeam 3 for support. An outer pry block 25 is installed on the bottom side of spring rod 9, and the top end of unlocking push ring 11 can push the outer pry block 25, and the wire extends into spring rod 9 away from the slot 10.

[0035] More specifically, the detection component 1 is first installed through the detection snap-fit ​​mechanism. The snap-fit ​​rod 8 is inserted into the snap-fit ​​tube 7 and automatically locked. Then, the detection position is adjusted using the translation adjustment mechanism. The adjustment bolt 21 is rotated to accurately position and lock the device. Next, the wall flatness is detected. Finally, when the detection component 1 needs to be replaced, the rotating sleeve 14 is rotated to activate the snap-fit ​​auxiliary mechanism, which drives the outer moving sleeve 13 to move upward to unlock the snap-fit ​​rod 8, thus completing the disassembly. The entire design emphasizes ease of operation and accuracy, significantly improving the efficiency and accuracy of wall flatness detection.

[0036] In summary, when the overall equipment is in use or running: when the translation adjustment mechanism needs to be running, the detection component 1 is accurately positioned through the gear transmission system. After the operator loosens the fixing bolt 6, the adjusting bolt 21 is rotated to drive the rotating gear 23 to rotate on the gear plate 22, driving the moving sleeve 5 to slide smoothly on the crossbeam 3. The scale plate 4 provides accurate position reference. When the desired position is reached, the fixing bolt 6 is tightened, and the compression spring block 24 is in close contact with the crossbeam 3, firmly locking the position of the moving sleeve 5 and ensuring positional stability during the measurement process.

[0037] When the snap-fit ​​mechanism needs to be tested, the detection component 1 can be quickly installed and disassembled. During installation, the snap-fit ​​rod 8 is inserted into the snap-fit ​​tube 7, and the extended spring rod 9 automatically embeds into the snap-fit ​​groove 10 on the side wall of the snap-fit ​​rod 8 to form a lock. At the same time, the side plate 20 and the mounting plate 401 are tightly fitted. During disassembly, the outer sliding sleeve 13 is pushed up to move the moving spring rod 12 and the unlocking push ring 11 upward. The unlocking push ring 11 pushes the outer pry block 25 on the extended spring rod 9, so that the extended spring rod 9 is disengaged from the snap-fit ​​groove 10, releasing the snap-fit ​​rod 8 and achieving quick separation.

[0038] When the auxiliary mechanism needs to be engaged, when the rotating sleeve 14 is rotated, the spiral plate 15 slides in the spiral groove 16, converting the rotational motion into the longitudinal movement of the outer sleeve 13. At the same time, the ball block 17 passes through the gaps between the shrink blocks 18 step by step. The shrink blocks 18 generate rhythmic contraction and release under the action of the shrink spring 19, providing clear tactile feedback to the operator and ensuring precise operation.

[0039] First, the detection component 1 is installed through the detection snap-fit ​​mechanism. The snap-fit ​​rod 8 is inserted into the snap-fit ​​tube 7 and automatically locked. Then, the detection position is adjusted using the translation adjustment mechanism. The adjustment bolt 21 is rotated to accurately position and lock the device. Next, the wall flatness is detected. Finally, when the detection component 1 needs to be replaced, the rotating sleeve 14 is rotated to activate the snap-fit ​​auxiliary mechanism, which moves the outer sleeve 13 upward to unlock the snap-fit ​​rod 8, completing the disassembly. The entire design emphasizes ease of operation and accuracy, significantly improving the efficiency and accuracy of wall flatness detection.
