Description

Technical Field

[0001] This utility model relates to the field of wall thickness detection technology, and more specifically, to a building wall thickness detection device. Background Technology

[0002] A building wall thickness measuring device is a tool specifically designed to measure the thickness of building walls, aiming to improve the accuracy, efficiency, and safety of the measurement. These devices are typically ingeniously designed, integrating advanced measurement technology and user-friendly operation.

[0003] Chinese Patent Publication No. CN218884921U discloses a building wall thickness detection device. This patent involves vertically positioning a detection rod close to the wall being measured. A touch screen adjusts the spacing between adjacent thickness detection components via a control spacing adjustment mechanism. Multiple thickness detection components are used to detect the thickness of the wall at different heights, and the detection results are sent to the touch screen for display. This invention can measure the thickness of a single wall at different heights simultaneously, saving time and effort, providing accurate results, and making it more convenient to use.

[0004] However, in the aforementioned patent, when measuring the wall thickness, there may be misalignment between the left and right sides during the placement process, which may lead to a slightly larger measured thickness and thus an inaccurate measurement. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] To address the problems existing in the prior art, the purpose of this utility model is to provide a building wall thickness detection device. It can measure the thickness of a wall by clamping it with a vertically downward calibration plate and a clamping plate. The downward force keeps the calibration plate stable against the wall, and the magnetic attraction of the electromagnet causes the magnetic sleeve to slide along the outer end of the measuring rod, which drives the clamping plate to clamp the wall between the clamping plate and the calibration plate for thickness detection. This effectively prevents detection errors caused by misalignment and greatly improves the accuracy of the detection device.

[0007] 2. Technical Solution

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0009] A wall thickness measuring device includes a hand-held rod with a receiving plate fixedly connected to its front end. A traction wire is fixedly connected to the lower end of the hand-held rod near the receiving plate, and a fixing rod is fixedly connected to the lower end of the traction wire. A calibration plate is fixedly connected to the side end of the fixing rod, and a measuring rod is fixedly connected to the side end of the calibration plate. An electromagnet is fixedly connected between the measuring rod and the calibration plate. A magnetic sleeve is slidably connected to the outer end of the measuring rod, and a clamping plate is fixedly connected to the side end of the magnetic sleeve. A switch is installed at the end of the hand-held rod away from the receiving plate, and a power source is installed inside the hand-held rod. The device measures the wall thickness by clamping it between the vertically downward-pointing calibration plate and clamping plate. The downward force keeps the calibration plate stable against the wall, and the magnetic attraction of the electromagnet causes the magnetic sleeve to slide along the outer end of the measuring rod, driving the clamping plate to clamp the wall between it and the calibration plate for thickness measurement. This effectively prevents measurement errors caused by misalignment and greatly improves the accuracy of the measuring device.

[0010] Furthermore, the calibration plate includes a base plate, which is fixedly connected to the side of the fixing rod. A liquid storage tank is provided on the upper end of the base plate, and the liquid storage tank is filled with liquid. A transparent plate is fixedly connected to the inner wall of the liquid storage tank, and a center marker is installed in the middle of the transparent plate. A floatation bladder is provided in the liquid. By floating in the liquid and coordinating with the position of the center marker, the overall detection device can be horizontally calibrated.

[0011] Furthermore, a counterweight plate is fixedly connected to the end of the fixed rod away from the calibration plate. The counterweight plate balances the weight at the lower end of the fixed rod, thereby ensuring that the detection part remains horizontal and vertically downward.

[0012] Furthermore, an anti-detachment plate is fixedly connected to the end of the measuring rod away from the calibration plate. The anti-detachment plate can limit the magnetic sleeve and prevent the magnetic sleeve from falling off the outer end of the measuring rod.

[0013] Furthermore, an auxiliary groove is provided at one end of the measuring rod near the clamping plate. An auxiliary block is slidably connected in the auxiliary groove and is fixedly connected to a magnetic sliding sleeve. An auxiliary spring is fixedly connected between the auxiliary block and the inner wall of the auxiliary groove. The auxiliary block slides within the auxiliary groove and can be reset by the rebound force of the auxiliary spring.

[0014] Furthermore, multiple anti-slip particles are fixedly connected to both the outer end of the grip rod and the end of the abutment plate away from the grip rod. These multiple anti-slip particles can increase friction, which can not only prevent the worker from slipping when gripping the rod, but also prevent the abutment plate from sliding when it is pressed against the wall.

[0015] 3. Beneficial effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] (1) This solution can achieve the purpose of measuring the thickness of the wall by clamping the vertically downward calibration plate and clamp. The downward force is used to keep the calibration plate stable against the wall, and the magnetic attraction of the electromagnet causes the magnetic sleeve to slide along the outer end of the measuring rod, which drives the clamp to clamp the wall between it and the calibration plate for thickness detection. This effectively prevents detection errors caused by misalignment and greatly improves the accuracy of the detection device.

[0018] (2) In this scheme, the calibration plate includes a base plate, which is fixedly connected to the side of the fixing rod. A liquid storage tank is opened at the upper end of the base plate. The liquid storage tank is filled with liquid. A transparent plate is fixedly connected to the inner wall of the liquid storage tank. A center mark is installed in the middle of the transparent plate. A floating bladder is provided in the liquid. By floating in the liquid and cooperating with the position of the center mark, the overall detection device can be horizontally calibrated.

[0019] (3) In this scheme, a counterweight plate is fixedly connected to the end of the fixed rod away from the calibration plate. The counterweight plate balances the weight of the lower end of the fixed rod, so that the detection part can remain horizontal and vertical downward.

[0020] (4) In this scheme, the end of the measuring rod away from the calibration plate is fixedly connected to an anti-detachment plate. The anti-detachment plate can limit the magnetic sleeve and prevent the magnetic sleeve from falling off the outer end of the measuring rod.

[0021] (5) In this scheme, an auxiliary groove is provided at one end of the measuring rod near the clamp. An auxiliary block is slidably connected in the auxiliary groove, and the auxiliary block is fixedly connected to the magnetic sliding sleeve. An auxiliary spring is fixedly connected between the auxiliary block and the inner wall of the auxiliary groove. The auxiliary block slides in the auxiliary groove and can be reset under the rebound force of the auxiliary spring.

[0022] (6) In this solution, multiple anti-slip particles are fixedly connected to the outer end of the hand grip and the end of the abutment plate away from the hand grip. The multiple anti-slip particles can increase friction, which can not only prevent the staff from slipping when gripping, but also prevent the abutment plate from sliding when it is against the wall.

[0032] Example 1:

[0033] Please see Figure 1-4A wall thickness detection device includes a handgrip 1, with a receiving plate 2 fixedly connected to the front end of the handgrip 1. A traction wire 3 is fixedly connected to the lower end of the handgrip 1 near the receiving plate 2. A fixing rod 4 is fixedly connected to the lower end of the traction wire 3. A calibration plate 5 is fixedly connected to the side end of the fixing rod 4. A measuring rod 6 is fixedly connected to the side end of the calibration plate 5. An electromagnet 7 is fixedly connected between the measuring rod 6 and the calibration plate 5. A magnetic sleeve 8 is slidably connected to the outer end of the measuring rod 6. A clamping plate 9 is fixedly connected to the side end of the magnetic sleeve 8. A switch is installed at the end of the handgrip 1 away from the receiving plate 2. A power supply is installed inside the handgrip 1. The wall thickness is measured by clamping it with the vertically downward calibration plate 5 and clamping plate 9. The downward force keeps the calibration plate 5 stable against the wall. Under the magnetic attraction of the electromagnet 7, the magnetic sleeve 8 slides along the outer end of the measuring rod 6, driving the clamping plate 9 to clamp the wall between it and the calibration plate 5 for thickness detection. This effectively prevents detection errors caused by misalignment and greatly improves the accuracy of the detection device.

[0034] The calibration plate 5 includes a base plate 51, which is fixedly connected to the side of the fixing rod 4. A liquid storage tank 52 is provided on the upper end of the base plate 51. The liquid storage tank 52 is filled with liquid. A transparent plate 53 is fixedly connected to the inner wall of the liquid storage tank 52. A center mark 54 is installed in the middle of the transparent plate 53. A float bladder 55 is provided in the liquid. By floating in the liquid and coordinating with the position of the center mark 54, the overall detection device can be horizontally calibrated.

[0035] A counterweight plate 10 is fixedly connected to the end of the fixed rod 4 away from the calibration plate 5. The counterweight plate 10 balances the weight of the lower end of the fixed rod 4, so that the detection part can remain horizontal and vertical downward.

[0036] An anti-detachment plate 11 is fixedly connected to the end of the measuring rod 6 away from the calibration plate 5. The anti-detachment plate 11 can limit the magnetic sliding sleeve 8 and prevent the magnetic sliding sleeve 8 from falling off the outer end of the measuring rod 6.

[0037] An auxiliary groove 12 is provided at one end of the measuring rod 6 near the clamping plate 9. An auxiliary block 13 is slidably connected in the auxiliary groove 12 and is fixedly connected to the magnetic sliding sleeve 8. An auxiliary spring 14 is fixedly connected between the auxiliary block 13 and the inner wall of the auxiliary groove 12. The auxiliary block 13 slides within the auxiliary groove 12 and can be reset by the rebound force of the auxiliary spring 14 after sliding.

[0038] Multiple anti-slip particles are fixedly connected to the outer end of the handle 1 and the end of the abutment plate 2 away from the handle 1. The multiple anti-slip particles can increase friction, which can not only prevent the staff from slipping when holding it, but also prevent the abutment plate 2 from sliding when it is pressed against the wall.

[0039] When using it, please refer to Figure 1-4The operator holds the lever 1 and places the contact plate 2 against the corner of the wall. Then, the traction wire 3 suspends the lower detection part against the wall, positioning the calibration plate 5 and the clamping plate 9 on opposite sides of the wall. A switch then activates the electromagnet 7, which attracts the magnetic sliding sleeve 8, causing the clamping plate 9 to move closer to the calibration plate 5. This clamps the calibration plate 5 and clamping plate 9 against the outer end of the wall. The reading on the outer end of the measuring rod 6 is then taken. Compared to traditional building wall thickness detection devices, this invention achieves the purpose of measuring the wall thickness by clamping the vertically downward calibration plate 5 and clamping plate 9. The downward force keeps the calibration plate 5 stable against the wall, and the magnetic attraction of the electromagnet 7 causes the magnetic sliding sleeve 8 to slide along the outer end of the measuring rod 6, moving the clamping plate 9 to clamp the wall between it and the calibration plate 5 for thickness detection. This effectively prevents detection errors caused by misalignment and greatly improves the accuracy of the detection device.

[0040] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
