Description

Technical Field

[0001] This utility model relates to the field of thickness detection technology, and in particular to a device for detecting the thickness of building exterior wall insulation materials. Background Technology

[0002] External wall insulation materials specifically refer to a type of insulation material used in building walls. Based on the location of use, they can be divided into: external wall insulation materials, internal wall insulation materials, and roof insulation materials. Based on the internal composition of the insulation materials, they can be divided into: inorganic insulation materials and organic insulation materials. There are requirements for the thickness of insulation materials; if the thickness is insufficient, the insulation effect will decrease.

[0003] However, existing testing devices mostly rely on manual hand-held fixation. During the testing process, they are easily affected by hand tremors or uneven wall surfaces, causing deviations and resulting in skewed insertion of the anchors. This can not only damage the insulation layer structure but also directly affect the accuracy of the test data. Furthermore, the anchors often lack a stable guiding structure, making them prone to radial wobbling during insertion. This makes it difficult for the equipment to quickly and accurately lock the anchor position, and the anchors are prone to displacement when the device is pulled out, resulting in large reading errors. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a device for detecting the thickness of building exterior wall insulation materials. It solves the technical problems of existing detection devices, such as easy deviation when manually operated, skewed nail direction, lack of stable guidance leading to easy shaking, difficulty in locking, and large reading errors caused by nail displacement when pulled out.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A device for detecting the thickness of building exterior wall insulation material includes a top plate, a bracket fixedly installed at the lower end of the top plate, a base plate fixedly installed at the lower end of the bracket, a first threaded ring threaded inside the bracket, a limit ring fixedly installed inside the first threaded ring, a column groove inside the top plate, sliding columns fixedly installed at equal intervals at the upper end of the top plate, springs sleeved on each of the sliding columns, cross blocks sleeved on each of the sliding columns, a nail slidably installed inside the column groove, the nail fixedly connected to the cross blocks, a scraper fixedly installed on the side wall of the nail, and a scale strip provided on the side wall of the nail, which can realize the stable sliding of the nail and the basis for depth detection. The scraper and the scale strip provide clear conditions for thickness reading.

[0007] Preferably, the cross block is provided with equidistant grooves, and multiple sliding columns are slidably installed in the grooves. Through the sliding cooperation between the grooves and the sliding columns, the radial displacement of the cross block is limited, ensuring that the nail is inserted into the insulation layer in a straight line, thereby improving the stability and accuracy of the detection process.

[0008] Preferably, the upper and lower ends of the plurality of springs are fixedly connected to the cross block and the top plate, respectively. The springs provide elastic restoring force, and can automatically rebound and reset after the nail is inserted, reducing manual operation steps, while buffering the insertion impact force to avoid damage to the nail.

[0009] Preferably, the lower end of the chassis has an inner groove, and mounting seats are fixedly installed at equal intervals inside the inner groove. The inner groove provides space for the mounting seats, and the equally spaced mounting seats ensure that the subsequent fixing structure is subjected to uniform force, laying the foundation for the stable positioning of the device.

[0010] Preferably, each of the mounting bases has a limiting groove, and each of the mounting bases is threaded with a second threaded ring. The limiting groove provides a guiding reference, and the second threaded ring can lock subsequent components, realizing quick disassembly and assembly and stable fixation of components, and improving the convenience of device maintenance.

[0011] Preferably, each of the mounting bases has an insert post inside. The insert structure simplifies the insertion post installation process, makes it easy to adjust the position of the insert post according to the wall conditions, and provides a flexible installation carrier for the subsequent adsorption and fixing structure.

[0012] Preferably, each of the insertion posts is symmetrically fixedly installed with a limiting strip, and each set of the limiting strips is respectively provided in each set of limiting grooves. The limiting strips cooperate with the limiting grooves to restrict the circumferential rotation of the insertion post, ensure the stability of the adsorption structure direction, and avoid the device from shifting during positioning, which would affect the detection accuracy.

[0013] Preferably, each of the insertion posts is fixedly equipped with a suction cup, and the nail is fixedly fitted with a positioning ring. The suction cup enables the device to be stably adsorbed on the wall, and the positioning ring, together with the limiting ring, locks the insertion depth of the nail, ensuring stable readings when the device is pulled out and improving detection accuracy.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This device uses a suction cup to achieve stable positioning of the device on the wall. With the guide sliding structure of the nail and the limiting ring and positioning ring, it can easily complete the operation of inserting the nail into the insulation material. The corresponding setting of the scraper and the scale strip can clearly read the insertion depth, realizing accurate and efficient detection of the insulation material thickness. It is easy to operate and has strong detection stability. Attached Figure Description

Detailed Implementation

[0022] This application provides a device for detecting the thickness of building exterior wall insulation materials. It effectively solves the problems of existing detection devices, such as easy deviation when manually operated, skewed nail direction, lack of stable guidance leading to wobbling, difficulty in locking, and large reading errors due to nail displacement during removal. This device uses a suction cup to achieve stable positioning on the wall. With the guide sliding structure of the nail and the limiting ring and positioning ring, the nail insertion into the insulation material can be completed conveniently. Furthermore, the corresponding setting of the scraper and the scale strip can clearly read the insertion depth, achieving accurate and efficient detection of the insulation material thickness. It is easy to operate and has strong detection stability.

[0023] Example

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in this application embodiment effectively solves the technical problems of existing detection devices, such as easy deviation when manually held, skewed nail direction, lack of stable guidance leading to easy shaking, difficulty in locking, and large reading errors caused by nail displacement when pulled out. The overall idea is as follows: A thickness detection device for building exterior wall insulation materials, comprising a top plate 1, a support 2, and a base plate 3, which are welded together from top to bottom to form the main frame of the device. The inner wall of the support 2 is machined with internal threads, which are adapted to the external threads of the first threaded ring 4. The inner wall of the first threaded ring 4 is fixed to the limiting ring 5 with an interference fit. A column groove 6 penetrating the upper and lower end faces is opened in the center of the top plate 1. 3-4 sliding columns 7 are welded vertically at equal intervals along the circumference of the upper end face of the top plate 1. Each sliding column 7 has... A spring 8 and a cross block 9 are fitted together, and a nail 11 slides through the groove 6. The upper end of the nail 11 is coaxially welded and fixed to the cross block 9. A scraper 12 is vertically welded to the lower part of the side wall of the nail 11, and a scale strip 13 is continuously engraved along the length of the nail 11, thus constructing a complete detection foundation for the device. The main frame ensures structural rigidity and avoids deformation during detection. The first threaded ring 4 and the limiting ring 5 provide structural support for locking the depth of the nail. The cross block 9 and the sliding column 7 cooperate to ensure the axial sliding stability of the nail 11. The scraper 12 can clean the insulation material debris on the surface of the scale strip 13. The scale strip 13 directly provides a thickness reading reference, solving the problems of unstable support and ambiguous readings in existing devices, and realizing the core implementation of the detection function.

[0025] The cross block 9 has a cross-shaped block structure with radially spaced grooves 10 at its four ends. The inner diameter of the groove 10 and the outer diameter of the sliding column 7 are fitted with a clearance fit. Each sliding column 7 is embedded in the groove 10 and can slide smoothly along the axial direction of the groove 10 without jamming. Through the precise fit between the groove 10 and the sliding column 7, the radial offset of the cross block 9 is limited, ensuring that the nail 11 can only move along the axial direction of the column groove 6. This avoids the problem of misalignment of the insertion direction and damage to the insulation layer caused by radial shaking when the nail is inserted into the insulation layer, thus improving the stability of the testing process and the positioning accuracy of the nail.

[0026] Each spring 8 is a cylindrical helical compression spring, which is naturally fitted around the slide column 7. The upper end of the spring 8 is fixed to the lower end face of the cross block 9 by welding, and the lower end is fixed to the upper end face of the top plate 1 by welding. The spring 8 and the slide column 7 are kept coaxial to ensure that there is no off-center load when the spring is extended or retracted. The spring 8 provides elastic restoring force. When the nail 11 is pushed into the insulation layer, the spring 8 is compressed and stores elastic force. After the test is completed, the pushing force is released, and the spring 8 can drive the cross block 9 and the nail 11 to automatically spring back to their original positions. There is no need to manually remove the nail, which reduces the operation steps. At the same time, the spring 8 can buffer the impact force when the nail is inserted, preventing the nail from bending or being damaged due to excessive instantaneous force, thus extending the service life of the components.

[0027] A circular inner groove 14 is provided in the center area of ​​the lower end face of the chassis 3. Three to four mounting seats 15 are welded at equal intervals along the circumference of the inner wall of the inner groove 14. The mounting seats 15 are fixed in a secondary manner by countersunk bolts. The inner groove 14 provides space for the mounting seats 15 to avoid the mounting seats 15 protruding from the end face of the chassis 3, which would prevent the device from adhering to the wall. The equally distributed mounting seats 15 can make the subsequent suction cup components evenly stressed, ensuring that the device does not tilt when adhering to the wall, solving the problem of easy displacement when the device is manually held, and laying the foundation for stable positioning of the device.

[0028] Each mounting base 15 has an external thread machined on its outer wall. Two limiting grooves 16 are symmetrically opened along the axial direction on the top of the mounting base 15, passing through the upper and lower end faces. The internal thread of the second threaded ring 17 is adapted to the external thread of the mounting base 15, and can rotate axially along the outer wall of the mounting base 15. After tightening, it can press against the insertion post 18 to achieve locking. The limiting groove 16 provides a guide channel for the limiting strip 19 of the insertion post 18, ensuring that the insertion post 18 can only move axially. The second threaded ring 17 can lock the insertion post 18 axially by tightening the thread, preventing the insertion post 18 from loosening during the detection process and causing the suction cup 20 to detach from the wall. When disassembling, the insertion post 18 can be removed simply by loosening the second threaded ring 17, which facilitates the replacement of the suction cup 20 after damage and improves the convenience of device maintenance.

[0029] Each mounting base 15 has a stepped hole in the center. The insert 18 is a cylindrical structure, and the diameter of its upper cylindrical section is adapted to the lower diameter of the stepped hole in the mounting base 15. The insert 18 is inserted into the stepped hole from the lower end of the mounting base 15 and can move along the hole axis to adjust the extension length. The insertion structure allows the insert 18 to flexibly adjust the extension length according to the flatness of the wall surface. Even if there are slight protrusions or depressions on the wall surface, the insert 18 can be adjusted to ensure that all suction cups 20 are tightly attached to the wall surface, avoiding the problem that some suction cups 20 cannot be adsorbed due to uneven wall surface and unstable device positioning, thus improving the adaptability of the device to different wall surfaces.

[0030] Each insertion post 18 has a symmetrically welded limiting strip 19 on its upper sidewall. The width of the limiting strip 19 is in clearance fit with the groove width of the limiting groove 16 of the mounting base 15. The thickness is 1 / 5 of the diameter of the insertion post 18. Each set of limiting strips 19 is embedded in the limiting groove 16 one by one. They can slide axially along the limiting groove 16 with the insertion post 18, but cannot rotate circumferentially. The fit between the limiting strip 19 and the limiting groove 16 completely restricts the circumferential rotation of the insertion post 18, preventing the insertion post 18 from rotating and causing the suction cup 20 to shift. This ensures that the adsorption direction of all suction cups 20 is consistent, further guaranteeing the overall positioning stability of the device and solving the defect of easy shifting after the existing device is fixed.

[0031] Each insertion post 18 has a suction cup 20 bonded to its lower end with strong waterproof adhesive. The positioning ring 21 is a ring structure and is fixed to the middle of the rivet 11 with an interference fit. The outer diameter of the positioning ring 21 is slightly smaller than the inner diameter of the limiting ring 5, so it can tightly abut against the lower end of the limiting ring 5. The suction cup 20 uses atmospheric pressure to tightly adhere to the wall surface, providing a reliable fixing force for the device, completely replacing manual hand-held fixing and avoiding detection errors caused by hand tremors. When the positioning ring 21 abuts against the limiting ring 5, it can accurately lock the insertion depth of the rivet 11. When the device is pulled out, the rivet 11 has no axial displacement. Combined with the scale strip 13 after cleaning by the scraper 12, the thickness of the insulation material can be directly read, solving the core problem of large reading errors in existing devices.

[0032] To address the problems existing in the prior art, this utility model provides a device for detecting the thickness of building exterior wall insulation materials. This device achieves stable positioning on the wall surface through a suction cup. With the guide sliding structure of the nail and the limiting ring and positioning ring, the nail insertion into the insulation material can be completed conveniently. Furthermore, the corresponding setting of the scraper and the scale strip can clearly read the insertion depth, achieving accurate and efficient detection of the insulation material thickness. It is easy to operate and has strong detection stability.

[0033] Working principle:

[0034] First, when using the device, the base 3 can be placed against the exterior wall of the building. At this time, the suction cup 20 inside the base 3 will adhere to the wall surface to stabilize the device. Then, the nail 11 can be pushed, and the positioning ring 21 will move with the nail 11, so that it is inserted into the insulation material of the exterior wall of the building. The movement of the nail 11 will drive the cross block 9 to move as well. The cross block 9 will drive the spring 8 to compress. Then, the first threaded ring 4 can be rotated inside the bracket 2. The rotation of the first threaded ring 4 will drive the limiting ring 5 to move. The limiting ring 5 will limit the positioning ring 21 as it moves. At this time, the device can be pulled out, and the measurement can be completed by reading the scale bar 13 on the scraper 12.

[0035] The second step is to remove the suction cup 20 by rotating the second threaded ring 17 on the mounting base 15. Then the insertion post 18 and the limiting strip 19 can be pulled out from the mounting base 15 and the limiting groove 16. At this time, the removal and replacement of the suction cup 20 can be completed.

[0036] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
