Description

Technical Field

[0001] This invention belongs to the field of building wall measurement technology, specifically a high-precision building wall verticality measuring device. Background Technology

[0002] In the quality control and safety inspection of construction projects, accurate measurement of wall verticality is a crucial step in ensuring structural stability, aesthetic regularity, and smooth progress of subsequent construction. With the continuous development of the construction industry, building forms are becoming increasingly diverse, from traditional regular rectangular walls to today's common irregularly shaped walls, right-angled walls, and even uneven walls with surface construction errors. This places higher demands on the adaptability of verticality measuring devices. However, currently widely used wall verticality measuring devices generally suffer from insufficient adaptability when facing these complex scenarios, becoming a core issue affecting measurement efficiency and accuracy. Traditional wall verticality measuring tools often struggle to achieve stable contact and flexible adjustment when dealing with walls of varying structures and surface conditions. For walls with uneven surfaces, most measuring devices can only achieve localized point contact with the probe, failing to establish a comprehensive and stable fit with the wall surface. This leads to data deviations during measurement and makes it difficult to accurately reflect the overall verticality of the wall. When dealing with right-angled or irregularly shaped walls, the fixed structure of existing devices cannot adapt to the angle and shape of the wall. To complete the measurement, it is usually necessary to replace the device with a special measuring accessory, which not only increases the complexity of the operation process but may also further affect the accuracy of the measurement results due to improper benchmark adjustment during accessory replacement. Based on this, a high-precision building wall verticality measuring device has been proposed to solve the above problems. Summary of the Invention

[0012] The beneficial effects of this invention are as follows: 1.

The hinged circular block, in conjunction with the insertion plate, provides an angle adjustment and locking structure that can adjust the measurement angle according to irregular structures such as right-angled walls, without the need to replace special accessories. The abutment spring drives the slide rod and the abutment block to achieve elastic buffer positioning, which can adapt to uneven wall surfaces. Combined with the rigid positioning driven by the dual-head motor, it ensures stable fit, effectively solving the problem of insufficient adaptability of traditional devices, and enabling the device to be used efficiently in various complex wall scenarios. 2. This invention utilizes a dual locking structure of T-shaped blocks and triangular blocks to firmly confine the fixed connecting rod within the fixed blocks, preventing vertical, horizontal, and angular offsets between the connecting and measuring components during measurement. The positioning and measuring components are synchronously linked by fixing the outer wall of the middle section of the connecting rod to the inner wall of the truss, preventing relative offset between the two from affecting the reference. The combination of elasticity and rigidity in the positioning component ensures a fully stable fit with the wall surface, avoiding reference deviations caused by localized point contacts. These designs collectively guarantee the stability of the measurement reference, thereby improving the accuracy of wall verticality measurement. 3. This invention uses a limiting spring to buffer the sliding speed of the limiting slider, preventing excessively rapid adjustment from causing the measuring component to shift, thus making the horizontal fine-tuning operation smoother. When the positioning component contacts the wall, it first achieves initial elastic positioning through the abutment block and the abutment spring, and then starts the dual-head motor for rigid positioning. The step-by-step operation reduces the difficulty of a single operation, and the automated positioning driven by the motor reduces human operation errors. The double locking structure of the limiting component can fix the connecting component without complicated operations, simplifying the operation process and avoiding the influence of external interference on the measurement, making the entire measurement process more stable and convenient.

Detailed Implementation

[0016] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0017] Example 1: As Figures 1 to 7As shown, the high-precision building wall verticality measuring device of this invention includes a receiving base plate 1, a connecting mechanism 2 disposed on the receiving base plate 1, the connecting mechanism 2 including a connecting component 21 disposed in the middle section of the receiving base plate 1, a measuring component 22 connected to the top of the connecting component 21, a positioning component 23 connected to the right side of the measuring component 22, and a limit component 24 disposed on the top of the receiving base plate 1; the positioning component 23 includes a connecting rod 231, a fixing crossbar 232 fixedly connected to the upper and lower ends of the connecting rod 231, and a connecting base fixedly connected to the right end of the fixing crossbar 232. A plate 233 is connected to a fixing block 234 at the upper and lower sections of the outer end of the connecting base plate 233. A slide rod 235 is slidably connected to the inner wall of the fixing block 234. An abutment spring 236 is sleeved on the outer wall of the outer section of the slide rod 235. Abutment blocks 237 are fixedly connected to both ends of the slide rod 235. A double-headed motor 238 is fixedly installed in the middle section of the outer wall of the connecting base plate 233. A threaded push rod 239 is fixedly connected to the upper and lower output ends of the double-headed motor 238. A traction block 2310 is threadedly connected to the outer wall of the threaded push rod 239. A measuring abutment plate 2311 is fixedly connected to the outer wall of the outer end of the traction block 2310.

[0018] In this embodiment, the positioning component 23, as a structure that directly contacts the wall, ensures stable contact with walls of different surface conditions, avoiding contact deviations caused by unevenness of the wall surface and guaranteeing the stability of the measurement reference. Before the positioning component contacts the wall, the dual-head motor 238 is in standby mode. Under the elastic action of the abutment spring 236, the slide rod 235 drives the abutment blocks 237 at both ends to extend outward. When the device approaches the wall, the abutment blocks 237 first contact the wall surface. If the wall surface is uneven, the abutment spring 236 can elastically deform according to the contact pressure, pushing the slide rod 235 to slide along the inner wall of the fixing block 234 and the connecting base plate 233, so that the abutment blocks... 237 remains in contact with the wall surface, achieving initial elastic buffer positioning. Subsequently, the dual-head motor 238 is activated, and its upper and lower output ends drive the threaded push rod 239 to rotate. Since the traction block 2310 is threadedly connected to the threaded push rod 239 and its sliding is restricted to the outer wall of the connecting base plate 233, the rotation of the threaded push rod is converted into the up-and-down linear motion of the traction block 2310, which in turn drives the measuring plate 2311 to move towards the wall until the measuring plate 2311 is tightly in contact with the wall surface, completing the rigid drive positioning. The outer wall of the middle section of the connecting round rod 231 is fixed to the inner wall of the truss 223 to ensure that the positioning component and the measuring component are synchronized and linked, avoiding the influence of relative offset between the two on the measurement results.

[0019] Furthermore, the outer wall of the middle section of the connecting rod 231 is fixedly connected to the inner wall of the truss 223, the sliding rod 235 is slidably connected to the inner wall of the connecting base plate 233, and the sliding rod 235 is symmetrically arranged on the upper and lower sections of the connecting base plate 233. The outer wall of the threaded push rod 239 is sleeved on the inner wall of the fixing block 234, and the traction block 2310 is slidably connected to the outer wall of the connecting base plate 233.

[0020] Furthermore, when the device approaches the wall, the abutment 237 first contacts the wall surface. If the wall surface is uneven, the abutment spring 236 can elastically deform according to the contact pressure, pushing the slide rod 235 to slide along the inner wall of the fixed block 234 and the connecting base plate 233, so that the abutment 237 always fits against the wall surface, achieving initial elastic buffer positioning. Subsequently, the dual-head motor 238 is started, and its upper and lower output ends drive the threaded push rod 239 to rotate. Since the traction block 2310 is threadedly connected to the threaded push rod 239 and its sliding is restricted to the outer wall of the connecting base plate 233, the rotation of the threaded push rod is converted into the up and down linear motion of the traction block 2310, which in turn drives the measuring abutment plate 2311 to move towards the wall until the measuring abutment plate 2311 is tightly fitted against the wall surface, completing rigid drive positioning.

[0021] Example 2: Based on Example 1, the connecting assembly 21 includes a limiting slide rod 211 fixedly connected to the inner wall of a limiting slide groove opened in the middle of the top of the receiving base plate 1. A limiting spring 212 is sleeved on the outer wall of the left section of the limiting slide rod 211. A limiting slider 213 is slidably connected to the outer wall of the limiting slide rod 211. A receiving sleeve 214 is fixedly connected to the top of the limiting slider 213. A receiving slide rod 215 is slidably connected to the inner wall of the top of the receiving sleeve 214. Connecting slide plates 216 are fixedly connected to the outer walls of the front and rear ends of the receiving slide rod 215. The component 214 is hinged to a hinged circular block 217, with a fixed connecting rod 218 fixedly connected to the top outer wall of the hinged circular block 217. A sliding plate 219 is slidably connected to the inner wall of the limiting groove on both sides of the top of the receiving sleeve 214. The measuring assembly 22 includes a measuring circular plate 221, with a connecting rod 222 rotatably connected to the inner wall of the measuring circular plate 221. A truss 223 is fixedly connected to the outer walls of the front and rear ends of the connecting rod 222. A measuring finger block 224 is fixedly connected to the inner wall of the limiting opening on the right section of the truss 223, and a measuring finger block 225 is fixedly connected to the outer wall of the right end of the truss 223. In this embodiment, after the device is placed in the measurement area, the receiving base plate 1 serves as a stable bottom support structure. The operator can adjust the horizontal position and angle of the measuring component 22 via the connecting component 21. The limiting slider 213 can slide horizontally along the limiting slide rod 211. During the sliding process, the limiting spring 212 buffers the sliding speed of the slider through its elastic force, preventing the measuring component from shifting due to excessive adjustment, thus achieving fine-tuning of the measuring component in the horizontal direction. The receiving slide rod 215 can slide back and forth along the inner wall of the receiving sleeve 214, carrying... The hinged circular block 217 at the top and the fixed connecting rod 218 move back and forth to meet the measurement needs of walls at different distances. The hinged circular block 217 has mutually perpendicular limiting grooves on both sides, and the insert plate 219 can slide along these grooves. When the angle of the measuring component needs to be adjusted, the operator can push the insert plate 219 to release the hinged circular block 217, rotate the fixed connecting rod 218 to the target angle, and then push the insert plate 219 again to engage with the limiting groove, thus locking the angle and ensuring that the measuring component maintains a suitable angle with the wall measuring surface. The measuring circular plate 221 is fixedly connected to the inner wall of the upper section of the fixed connecting rod 218. The connecting rod 222, which is rotatably connected to the inner wall, can rotate with the change of wall verticality. When the positioning component is stably attached to the wall, if there is a verticality deviation in the wall, it will be transmitted to the truss 223 through the measuring abutment plate 2311, traction block 2310, threaded push rod 239, connecting base plate 233, fixed crossbar 232 and connecting circular rod 231, causing the truss 223 to shift angularly with the tilt direction of the wall. Since the truss 223 is fixedly connected to the connecting rod 218, the verticality deviation of the wall is not specified. At the front and rear ends of rod 222, the offset of the truss will cause the connecting rod 222 to rotate along the inner wall of the measuring circular plate 221; the measuring finger block 1 224 and the measuring finger block 225 on the right end of the truss 223 will change with the angle of the truss. The measuring circular plate 221 is marked with a scale, which will cause a positional offset. The operator can calculate the verticality deviation value of the wall by observing the scale position of measuring finger block 1 224 and measuring finger block 225 on the measuring circular plate 221, thus achieving high-precision measurement.

[0022] Furthermore, the hinged circular block 217 has limit grooves on both sides, and the limit grooves on both sides are perpendicular to each other. The insert plate 219 is slidably connected to the limit grooves. The measuring circular plate 221 is fixedly connected to the inner wall of the upper section of the fixed connecting rod 218, and the truss 223 is fixedly connected to the front and rear ends of the connecting rod 222.

[0023] Furthermore, when it is necessary to adjust the angle of the measuring component, the operator can push the insert plate 219 to release the fixation of the hinged circular block 217, rotate the fixed connecting rod 218 to the target angle, and then push the insert plate 219 again to engage with the limiting slide groove to complete the angle locking, ensuring that the measuring component and the wall measuring surface maintain an appropriate angle; the measuring circular plate 221 is fixedly connected to the inner wall of the upper section of the fixed connecting rod 218, and the connecting rod 222 rotatably connected to its inner wall can rotate with the change of the wall verticality.

[0024] Example 3: Based on Example 1, the limiting component 24 includes a fixing block 241 fixedly connected to the front top of the receiving base plate 1. A connecting spring 242 is fixedly connected to the bottom of the inner wall of the fixing block 241. A T-shaped block 243 is fixedly connected to the top of the connecting spring 242. A connecting rod 244 is fixedly connected to the outer walls of the front and rear ends of the T-shaped block 243. A push spring 245 is sleeved on the outer wall of the inner side of the connecting rod 244. An L-shaped rod 247 is slidably connected to the outer wall of the connecting rod 244. A triangular block 246 is fixedly connected to the top of the L-shaped rod 247. A limiting traction block 248 is fixedly connected to the front and rear ends of the T-shaped block 243.

[0025] In this embodiment, after the connecting component is adjusted to the target position and angle, the fixed connecting rod 218 will be embedded in the receiving groove at the top middle section of the fixed block 241. The T-shaped block 243 moves upward under the elastic force of the connecting spring 242, and its top is inserted into the limiting slide groove opened on the front of the fixed connecting rod 218, achieving initial limiting. The limiting traction blocks 248 at the front and rear ends of the T-shaped block 243 move upward with the T-shaped block, driving the connecting rod 244 to move synchronously. Since the L-shaped rod 247 is slidably connected to the limiting slide at the bottom of the receiving groove, The inner wall, and the push spring 245 is sleeved on the inner outer wall of the connecting rod 244. The push spring 245 will push the L-shaped rod 247 to slide inward, so that the triangular block 246 at the top of the L-shaped rod 247 will also be locked into the limiting groove on the front of the fixed connecting rod 218, forming a double locking structure. The double locking can effectively limit the vertical, horizontal and angular displacement of the fixed connecting rod 218 during the measurement process, ensuring that the connecting component and the measuring component remain stable, avoiding the displacement of the measurement reference due to external interference, and further ensuring the measurement accuracy.

[0026] Furthermore, a receiving groove is provided in the middle of the top of the fixed block 241, and the outer wall of the fixed connecting rod 218 is slidably connected to the inner wall of the receiving groove. The T-shaped block 243 is slidably connected to the inner wall of the fixed block 241, the L-shaped rod 247 is slidably connected to the inner wall of the limiting slide opening at the bottom of the receiving groove, and the top of the T-shaped block 243 and the triangular block 246 are slidably connected to the inner wall of the limiting slide groove on the front of the fixed connecting rod 218.

[0027] Furthermore, the limiting traction blocks 248 at the front and rear ends of the T-shaped block 243 move upward with the T-shaped block, causing the connecting rod 244 to move synchronously. Since the L-shaped rod 247 is slidably connected to the inner wall of the limiting slide at the bottom of the receiving groove, and the push spring 245 is sleeved on the inner outer wall of the connecting rod 244, the push spring 245 will push the L-shaped rod 247 to slide inward, so that the triangular locking block 246 at the top of the L-shaped rod 247 is also locked into the limiting slide groove on the front of the fixed connecting rod 218, forming a double locking structure.

[0028] Working principle: After the device is placed in the measurement area, the receiving base plate 1 serves as a stable bottom support structure. The operator can adjust the horizontal position and angle of the measuring component 22 through the connecting component 21. The limiting slider 213 can slide horizontally along the limiting slide rod 211. During the sliding process, the limiting spring 212 buffers the sliding speed of the slider through elastic force, preventing the measuring component from shifting due to excessive adjustment, thus achieving fine adjustment of the measuring component in the horizontal direction. The receiving slide rod 215 can slide back and forth along the inner wall of the receiving slide sleeve 214, driving the hinged circular block at the top. 217 and the fixed connecting rod 218 can move back and forth to meet the measurement needs of walls with different front and rear distances; the hinged round block 217 has mutually perpendicular limiting grooves on both sides, and the insert plate 219 can slide along the limiting groove. When it is necessary to adjust the angle of the measuring component, such as to adapt to the angle of a right-angle wall, the operator can push the insert plate 219 to release the fixation of the hinged round block 217, rotate the fixed connecting rod 218 to the target angle, and then push the insert plate 219 again to lock into the limiting groove to complete the angle locking and ensure that the measuring component and the wall measuring surface maintain an appropriate angle. The positioning component 23, as a structure that directly contacts the wall, ensures stable contact with walls of different surface conditions, avoiding contact deviations caused by unevenness of the wall surface and guaranteeing the stability of the measurement reference. Before the positioning component contacts the wall, the dual-head motor 238 is in standby mode. Under the elastic action of the abutment spring 236, the slide rod 235 drives the abutment blocks 237 at both ends to extend outward. When the device approaches the wall, the abutment blocks 237 first contact the wall surface. If the wall surface is uneven, the abutment spring 236 can undergo elastic deformation according to the contact pressure, pushing the slide rod 235 to slide along the inner wall of the fixing block 234 and the connecting base plate 233, so that the abutment blocks 237 initially... Finally, the device adheres to the wall surface, achieving initial elastic buffer positioning. Subsequently, the dual-head motor 238 is activated, and its upper and lower output ends drive the threaded push rod 239 to rotate. Since the traction block 2310 is threadedly connected to the threaded push rod 239 and its sliding is restricted to the outer wall of the connecting base plate 233, the rotation of the threaded push rod is converted into the up-and-down linear motion of the traction block 2310, which in turn drives the measuring plate 2311 to move towards the wall until the measuring plate 2311 is tightly attached to the wall surface, completing the rigid drive positioning. The outer wall of the middle section of the connecting round rod 231 is fixed to the inner wall of the truss 223 to ensure that the positioning component and the measuring component are synchronized and linked, avoiding the influence of relative offset between the two on the measurement results. The measuring circular plate 221 is fixedly connected to the inner wall of the upper section of the fixed connecting rod 218. The connecting rod 222, which is rotatably connected to the inner wall, can rotate with changes in the verticality of the wall. When the positioning component is stably attached to the wall, if there is a verticality deviation in the wall, such as the wall tilting to one side, it will be transmitted to the truss 223 through the measuring abutment plate 2311, traction block 2310, threaded push rod 239, connecting base plate 233, fixed crossbar 232 and connecting circular rod 231, causing the truss 223 to shift angularly with the tilt direction of the wall. Since the truss 223 is fixed... Connected to the front and rear ends of the connecting rod 222, the offset of the truss will cause the connecting rod 222 to rotate along the inner wall of the measuring circular plate 221; the measuring finger block 1 224 and the measuring finger block 225 on the right end of the truss 223 will change with the angle of the truss. The measuring circular plate 221 is marked with a scale, which will cause a positional offset. The operator can calculate the verticality deviation of the wall by observing the scale position of the measuring finger block 1 224 and the measuring finger block 225 on the measuring circular plate 221, thus achieving high-precision measurement. After the connecting components are adjusted to the target position and angle, the fixed connecting rod 218 will be embedded in the receiving groove at the top middle section of the fixed locking block 241. The T-shaped block 243 moves upward under the elastic force of the connecting spring 242, and its top is locked into the limiting slide groove opened on the front of the fixed connecting rod 218, achieving initial limiting. The limiting traction blocks 248 at the front and rear ends of the T-shaped block 243 move upward with the T-shaped block, driving the connecting rod 244 to move synchronously. Since the L-shaped rod 247 is slidably connected to the inner wall of the limiting slide at the bottom of the receiving groove, and The push spring 245 is sleeved on the inner outer wall of the connecting rod 244. The push spring 245 will push the L-shaped rod 247 to slide inward, so that the triangular block 246 at the top of the L-shaped rod 247 will also be engaged in the limiting groove on the front of the fixed connecting rod 218, forming a double locking structure. The double locking can effectively limit the vertical, horizontal and angular displacement of the fixed connecting rod 218 during the measurement process, ensuring that the connecting component and the measuring component remain stable, avoiding the displacement of the measurement reference due to external interference, and further ensuring the measurement accuracy.
