Cutting requires the use of a cutting knife and a measuring tape, resulting in a large number of tools needed for the test and affecting the efficiency of testing the bonding strength of the external insulation layer. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a retractable external wall insulation layer bonding strength testing device. This solves the problem that existing methods for conducting pull-out tests on external insulation layers typically require cutting the wall surface first, then attaching the test block to the center of the cut area, and finally pulling the test block after a period of time. The cutting process requires the use of a cutting knife and a measuring tape, resulting in a large number of tools needed for the test and affecting the efficiency of testing the bonding strength of the external insulation layer.

[0006] The purpose and effectiveness of this utility model, a retractable external wall insulation layer bonding strength testing device, are achieved through the following specific technical means: A retractable external wall insulation layer bonding strength testing device includes a pull-out tester body, pull-out support legs, a pull-out rod, a test block, a test drive box, a test drive slider, a test drive mechanism, and a test cutting mechanism. Two sets of pull-out support legs are fixedly connected to the left and right rear sides of the pull-out tester body. The pull-out rod is slidably and rotatably connected to the pull-out tester body with a clearance fit. The rear end of the pull-out rod has a threaded structure, and a slot is formed in the middle of the pull-out rod. The test block is threadedly connected to the rear end of the pull-out rod. The test drive box is fixedly connected above the pull-out tester body. The test drive slider is slidably connected to the lower inner side of the test drive box, with its lower end positioned inside the slot of the pull-out rod. The test drive mechanism is located inside the test drive box. The test cutting mechanism is located outside the pull-out rod.

[0007] Furthermore, the detection drive mechanism includes a detection drive motor; the detection drive motor is fixedly connected to the top of the detection drive box.

[0008] Furthermore, the detection drive mechanism also includes a detection drive worm and a detection drive worm wheel; the detection drive worm is rotatably connected inside the detection drive housing, and the detection drive worm is coaxially and fixedly connected to the output shaft of the detection drive motor; the detection drive worm wheel is rotatably connected inside the detection drive housing, and the detection drive worm wheel meshes with the detection drive worm.

[0009] Furthermore, the detection drive mechanism also includes a detection drive screw; the detection drive screw is rotatably connected inside the detection drive housing, and the detection drive screw is coaxially and fixedly connected to the detection drive worm gear.

[0010] Furthermore, the detection and cutting mechanism includes: a cutting guide and a cutting component; two sets of cutting guides are provided, and the two sets of cutting guides are respectively fixedly connected to the left and right sides of the rear end of the pull-out tester body; the cutting component is slidably connected to the rear of the cutting guides, and the cutting component is a rectangular structure with an open bottom end.

[0011] Furthermore, the detection and cutting mechanism also includes: a cutting fixing component, a cutting telescopic component, and an adjusting nut; the cutting fixing component is fixedly connected to the rear end of the detection drive slider, and the cutting fixing component is a cylindrical structure; the cutting telescopic component is fixedly connected to the front end of the cutting component, the cutting telescopic component is located inside the cutting fixing component, and the outer side of the cutting telescopic component is provided with a threaded structure; the adjusting nut is rotatably connected to the rear end of the cutting fixing component, and the adjusting nut is threadedly connected to the cutting telescopic component.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This invention utilizes a detection drive mechanism to adhere a test block to the outer side of the test wall. After the adhesive on the test block has completely solidified, a pull rod is threadedly connected to the test block. Turning on the detection drive motor causes its output shaft to rotate, which in turn rotates the detection drive worm gear. This rotation, in turn, rotates the detection drive worm wheel, which in turn rotates the detection drive screw. The screw then moves the detection drive slider forward, which in turn moves the pull rod forward. This forward movement of the pull rod applies tension to the insulation layer through the test block, thus enabling the detection of the insulation layer's bonding strength. This eliminates the need for manual operation by testing personnel, ensures uniform application of tension, and improves the accuracy of the insulation layer bonding strength test results.

[0013] This invention utilizes a detection and cutting mechanism. Rotating the adjusting nut moves the cutting telescopic component, adjusting the distance between the cutting component and the detection drive slider, thus controlling the cutting depth. During cutting, as the detection drive slider moves backward, it moves the cutting fixing component backward, which in turn moves the adjusting nut backward, which in turn moves the cutting telescopic component backward, ultimately cutting the insulation layer. This precise control of the cutting depth allows for adaptation to different thicknesses of external wall insulation layers, preventing damage to the wall substrate from excessive cutting or insulation layer detachment during subsequent testing from insufficient cutting. No additional cutting equipment is required, reducing the need for testing tools, simplifying the operation process, and improving testing efficiency. Furthermore, the stable transmission throughout the cutting process ensures a neat cutting trajectory, providing complete and qualified test samples for subsequent bonding strength testing and reducing testing errors caused by non-standard cutting.
