Description

Technical Field

[0001] This utility model belongs to the field of building material measurement technology, specifically relating to a humidity detector for building walls. Background Technology

[0002] The purpose of building wall humidity detectors is to solve the problem of building dampness. Excessive humidity inside the walls can lead to a variety of problems, including but not limited to mold growth, rotting of structural materials, reduced insulation, and impact on indoor air quality. These problems can not only damage the structural integrity of the building but also have negative effects on human health. Before the advent of humidity detectors, people usually relied on visual inspection, tactile judgment, or simple moisture test strips to assess wall humidity. These methods are often not accurate enough, cannot provide quantitative data, and cannot make a judgment on dampness problems hidden inside the walls.

[0003] In existing technologies, wall humidity detection typically requires drilling a small hole in the wall surface and then inserting the electrodes of the tester into the wall material. The humidity level is determined by measuring the resistance or conductivity of the wall material. However, after each measurement, when the tester is removed, some wall material often adheres to the electrodes. If the tester surface is not thoroughly cleaned, it may affect the accuracy of subsequent measurements. In addition, since the tester is usually exposed to the elements for extended periods when not in use, this not only increases the risk of accidental collisions or physical damage to the electrodes but may also cause the sensor to be affected by environmental factors such as dust and moisture, reducing its performance and lifespan.

Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0026] Example

[0027] Reference Figures 1-5 This is an embodiment of the present invention, which provides a house wall humidity detector, comprising:

[0028] The drive mechanism 100 includes a fixed post 101, a plurality of fixed rods 102 fixedly installed on the outer surface of the fixed post 101, a limiting groove 103 formed on the outer surface of the fixed rods 102, a sliding post 104 slidably connected to the inner surface of the limiting groove 103, a handle 105 fixedly installed on the outer surface of the sliding post 104, and a plurality of springs 106 fixedly installed on the outer surface of the fixed post 101.

[0029] The telescopic mechanism 200 includes a fixed frame 201 fixedly connected to the outer surface of the fixed post 101, a hinge rod 202 fixedly installed on the outer surface of the handle 105, a connecting plate 203 fixedly connected to the other end of the hinge rod 202, a guide groove 204 formed on the outer surface of the fixed frame 201 and used in conjunction with the hinge rod 202, a measuring device 205 fixedly installed on the outer surface of the connecting plate 203, a fixing sleeve 206 sleeved on the outer surface of the measuring device 205, several scrapers 207 fixedly installed on the inner wall surface of the fixed frame 201, a transmission assembly 208 for telescopic use of the measuring device 205, and a protective assembly 209 used in conjunction with the transmission assembly 208.

[0030] Specifically, the outer surface of the sliding column 104 slides in contact with the inner surface of the limiting groove 103, the other end of the spring 106 is fixedly connected to the outer surface of the handle 105, the outer surface of the hinge rod 202 slides in contact with the inner surface of the guide groove 204, and the inner surface of the scraper 207 is in contact with the outer surface of the measuring device 205.

[0031] The scraper 207 adheres to the measuring device 205, ensuring that complex building material residues on its outer surface are effectively removed whether the measuring device is extending for measurement or retracting for reset. This prevents measurement inaccuracies caused by building material residues and guarantees the accuracy of each measurement.

[0032] Furthermore, the transmission assembly 208 includes a rack 208a fixedly mounted on the outer surface of the fixed sleeve 206, a support rod 208b rotatably connected to the inner wall surface of the fixed frame 201, a first spur gear 208c fixedly mounted on the outer surface of the support rod 208b and meshing with the surface of the rack 208a, and a drive bevel gear 208d fixedly mounted on the outer surface of the rack 208a.

[0033] Furthermore, the transmission assembly 208 also includes a transmission rod 208e rotatably connected to the inner wall surface of the fixed frame 201, and a driven bevel gear 208f fixedly installed on the outer end face of the transmission rod 208e and meshing with the surface of the drive bevel gear 208d.

[0034] Furthermore, a bearing sleeve for rotation is installed at the connection between the support rod 208b and the fixed frame 201, and a bearing sleeve for rotation is installed at the connection between the transmission rod 208e and the fixed frame 201.

[0035] When the handle 105 is held, the hinge rod 202 pushes the connecting plate 203 to move. The connecting plate 203 drives the rack 208a to move together. During the movement, the rack 208a drives the first spur gear 208c to rotate. The first spur gear 208c drives the support rod 208b to rotate. Through the support rod 208b, the drive bevel gear 208d rotates. At the same time, the driven bevel gear 208f, which meshes with the drive bevel gear 208d, rotates accordingly and triggers the opening of the protective component 209.

[0036] Preferably, the protective assembly 209 includes a second spur gear 209a fixedly mounted on the outer end face of the transmission rod 208e, a drive gear plate 209b fixedly mounted on the outer surface of the fixed frame 201 and meshing with the surface of the second spur gear 209a, and an inner gear disk 209c rotatably connected to the outer surface of the drive gear plate 209b.

[0037] It should be noted that the protective component 209 also includes a slider 209d that is slidably connected to the outer surface of the drive tooth plate 209b, a positioning disk 209e that is fixedly installed on the outer surface of the drive tooth plate 209b, and a positioning groove 209f that is formed on the outer surface of the positioning disk 209e and used in conjunction with the slider 209d.

[0038] When the driven bevel gear 208f rotates, it drives the transmission rod 208e to rotate as well. The transmission rod 208e drives the second spur gear 209a to rotate. The second spur gear 209a meshes with the internal gear disk 209c, causing the internal gear disk 209c to rotate accordingly. The rotation of the internal gear disk 209c drives the drive slider 209d to move along a preset motion trajectory, ensuring that the slider 209d can move smoothly and accurately along the predetermined path to complete the opening and closing actions.

[0039] When in use, gripping the handle 105 and applying force causes the sliding column 104 to slide along the limiting groove 103, moving the hinge rod 202. The hinge rod 202 pushes the connecting plate 203, causing the entire telescopic mechanism 200 to start operating. The movement of the connecting plate 203 causes the rack 208a to move along the guide groove 204. The rack 208a meshes with the first spur gear 208c, causing the first spur gear 208c to rotate. When the first spur gear 208c rotates, it causes the support rod 208b to rotate accordingly. This motion is transmitted to the driven bevel gear 208f through the driving bevel gear 208d. The rotation of the driven bevel gear 208f further drives the transmission rod 208e to rotate, thereby activating the protective component 209 and the transmission... The rotation of rod 208e drives the second spur gear 209a to rotate. The second spur gear 209a meshes with the drive gear plate 209b, causing the inner gear disk 209c to rotate. The rotation of the inner gear disk 209c drives the slider 209d to move along the positioning groove 209f on the positioning disk 209e, ensuring that the slider 209d smoothly and accurately completes the opening and closing actions according to the preset trajectory, and enabling the measuring device 205 to measure the wall. During the extension or retraction of the measuring device 205, the scraper 207 closely adheres to the surface of the detection head, effectively removing the building material residues attached to it, preventing these residues from affecting the accuracy of the next measurement. At the same time, the protective component closes to protect the equipment from external factors.

[0040] In summary, through the cooperation of the drive mechanism 100 and the telescopic mechanism 200, the building material residues adhering to the measuring instrument 205 can be effectively removed during each use, ensuring that the measuring instrument 205 is always clean, thereby avoiding measurement errors caused by residues and ensuring high-precision measurement. At the same time, when not in use, the protective component 209 can provide comprehensive protection for the measuring instrument 205, preventing accidental collisions or physical damage, and reducing the impact of external environmental factors such as dust and moisture, thereby extending the service life of the equipment.
