[0002] The penetration tester is a testing instrument used for rapid on-site testing of the strength of masonry mortar. It is characterized by its light weight, simple operation, and high testing accuracy, reducing the workload of testing personnel and improving testing efficiency. It is a replacement for methods such as the rebound method and the in-situ ejection method.

[0003] Currently, in practical use, most penetrating mortar strength testers first insert a penetrating nail into the mortar, then remove the nail, blow out the dust from the hole using a blower, and then use a depth measuring device to measure the depth of the penetration hole. The strength of the mortar is then determined by referring to a mortar strength comparison table based on the measured depth. This testing method requires the preparation of multiple devices, making the measurement process cumbersome, inefficient, and inconvenient to carry. Utility Model Content

The snap ring 7 is located inside the snap groove 8.

[0029] A fixed rod 9 is fixedly mounted on the top of the upper locking plate 6. A telescopic rod 10 is located at the top of the fixed rod 9. A movable cavity 18 is formed inside the fixed rod 9, and a limiting movable block 19 is located inside the movable cavity 18. The bottom end of the telescopic rod 10 extends into the movable cavity 18 and is fixedly connected to the limiting movable block 19. A connecting rod 11 is fixedly connected to the top of the telescopic rod 10. A fixed plate 12 is fixedly mounted on the top of the main body 1 of the penetration mortar strength tester. A movable groove 24, communicating with the interior of the connecting port 2, is located on the top of the main body 1 of the penetration mortar strength tester. The movable groove 24 is located at one end of the fixed plate 12. The movable groove 24 corresponds to the dimensions of the fixed rod 9 and the telescopic rod 10. The top of the fixed plate 12 is provided with a measuring groove 13. One end of the connecting rod 11 extends into the measuring groove 13. One end of the connecting rod 11 is fixed with an indicator block 14. The top of the fixed plate 12 is provided with a scale line 15. The scale line 15 is located on both sides of the measuring groove 13. A sliding groove 16 is provided on both sides of the inner side wall of the measuring groove 13. A slider 17 is fixed on both sides of one end of the connecting rod 11. The two sliders 17 are respectively located inside the two sliding grooves 16.

[0030] Both ends of the lower locking plate 5 are integrally connected to a first connecting ear 20, and both ends of the upper locking plate 6 are integrally connected to a second connecting ear 21. The top of the first connecting ear 20 is fixedly connected to a fixing screw 22. The top of the fixing screw 22 passes through the second connecting ear 21 and extends to the top of the second connecting ear 21. The top of the fixing screw 22 is threadedly connected to a wing nut 23, which is located at the top of the second connecting ear 21.

[0031] The main body 1 of the penetration mortar strength tester is fixedly connected to a protective frame 25 at one end. The protective frame 25 is located outside the connecting port 2 and the test nail seat 3. Two abutment blocks 26 are fixedly connected to one end of the protective frame 25.

[0032] The internal structure of the main body 1 of the penetration mortar strength tester is the same as that of existing penetration mortar strength testers. These structures are existing technology and will not be shown in detail here. Insert one end of the penetration nail 4 into the nail holder 3 and tighten the two wing nuts 23. This will lock the nail holder 3 in place by the lower locking plate 5 and the upper locking plate 6, thus fixing one end of the penetration nail 4 inside the nail holder 3. At this point, the tester is in the following state: Figure 1 As shown, the detector is then wound up, and its state at this time is as follows. Figure 2As shown, the two abutment blocks 26 are brought into contact with the mortar surface to be tested, and then the switch is activated. The elastic structure inside the main body 1 of the penetration mortar strength tester will drive the test nail seat 3 and the penetration nail 4 to penetrate into the mortar. At this time, the test nail seat 3 drives the lower locking plate 5 and the upper locking plate 6 to move synchronously. The upper locking plate 6 drives the fixed rod 9 and the telescopic rod 10 to move synchronously. The telescopic rod 10 drives the connecting rod 11 and the indicator block 14 to move synchronously. At this time, observe the indication of the indicator block 14 to the scale line 15, and then directly read the distance that the indicator block 14 has moved. In this way, the penetration depth of the penetration nail 4 can be directly obtained. Then, the mortar strength can be obtained by directly looking up the reference table.

[0033] This invention uses a fixed rod 9, a telescopic rod 10, and a connecting rod 11 to synchronously link the test nail holder 3, the upper locking plate 6, and the indicator block 14. While the test nail holder 3 and the penetrating nail 4 move and penetrate, the moving distance of the test nail holder 3 and the penetrating nail 4 can be directly obtained through the indicator block 14 and the scale line 15, thus directly determining the penetration depth of the penetrating nail 4. This reduces the need for subsequent air blowing and hole depth measurement steps, making the mortar strength measurement process more convenient and efficient. Furthermore, it eliminates the need to carry air blowing and depth measurement equipment, making the instrument more portable. For convenience, this embodiment specifically addresses the problem that existing penetrating mortar strength testers, in practical use, mostly involve first inserting a penetrating nail into the mortar, then removing the nail, using a blower to remove dust from the hole, and then using a depth measuring structure to measure the depth of the penetration hole. The mortar strength is then determined by referring to a mortar strength comparison table based on the measured depth. This testing method requires multiple pieces of equipment, making the measurement process cumbersome, inefficient, and inconvenient to carry.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
