Description

Technical Field

[0001] This utility model relates to the field of building testing equipment, and in particular to a penetration mortar strength tester for building testing. Background Technology

[0002] In the field of construction engineering, strength testing of masonry mortar is a crucial step in ensuring project quality. A penetration tester is a testing instrument used for rapid on-site testing of masonry mortar strength.

[0003] When a penetration tester inserts a test pin into the mortar, a certain amount of dust is often generated in the test hole. This dust mainly consists of tiny particles in the mortar and impurities in the air. During the insertion process, these particles are squeezed and accumulate in the test hole. Existing penetration testers only use a blower to clean the dust in the test hole. It is difficult to completely blow out the dust deep in the test hole by relying solely on the air force of the blower. Especially when the mortar strength is high and the test hole is deep, the dust accumulation problem is more serious and has a greater impact on the test accuracy. Utility Model Content

[0004] To solve the problems mentioned above, this utility model achieves its goals through the following technical solution:

[0005] A penetration tester for building inspection includes: a tester body for testing mortar strength; a first handle mounted on the tester body; a second handle disposed on one side of the tester body, symmetrically arranged with the first handle, the second handle being configured to move closer to or further away from the tester body; a fixed rod, one end of which is mounted on the tester body, the second handle being disposed on the fixed rod; and a cleaning head connected to one end of the fixed rod, configured to rotate on the fixed rod when the fixed rod moves on the second handle, for cleaning dust inside the test hole.

[0006] The second handle includes: a through hole, which is located at one end of the second handle, and the fixing rod and the cleaning head are both located inside the through hole; a washer, which is installed at one end of the second handle; two air holes, which are located on the inner wall of the through hole and extend out from one end of the second handle; and two air bladders, which are installed at one end of the second handle, and the two air bladders are respectively connected to the two air holes. When the air bladders are squeezed, they blow air into the air holes.

[0007] The second handle also includes an elastic element, one end of which is mounted on the detector body and the other end of which is mounted on the second handle. The elastic element is used to provide a restoring force for the second handle to its initial position.

[0008] It also includes: a rotating rod, mounted on a fixed rod and disposed within a through hole, a cleaning head mounted on the rotating rod, the rotating rod being configured to rotate on the fixed rod to drive the cleaning head to rotate.

[0009] The rotating rod includes: a movable groove formed on the rotating rod, and a fixing block installed on the inner wall of the through hole, the fixing block being connected inside the movable groove; the movable groove is spiral-shaped.

[0010] The cleaning head has several protrusions for cleaning dust inside the measuring hole.

[0011] This utility model provides a penetration mortar strength tester for building testing. Compared with the prior art, it has the following advantages:

[0012] 1. By introducing a rotating rod and a cleaning head, the cleaning head rotates while moving on the fixed rod, effectively improving the cleaning effect of dust in the test hole. Several protrusions on the cleaning head can more thoroughly clean the dust, reduce the impact of dust on the detection accuracy, and improve the accuracy and reliability of mortar strength testing.

[0013] 2. The spiral moving groove of the rotating rod cooperates with the fixed block on the inner wall of the through hole, so that when the fixed rod is pushed, the rotating rod can rotate automatically, which drives the rotation of the cleaning head, improves the efficiency of dust cleaning, and shortens the detection preparation time.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Reference Figures 1-4 A penetration-type mortar strength tester for building inspection includes: a tester body 1, used to test mortar strength, providing accurate and reliable test data to help engineers or construction personnel judge the quality of mortar; a first handle 2, installed on the tester body 1, for easy gripping and operation by the user, improving ease of use and comfort; a second handle 3, located on one side of the tester body 1, symmetrically arranged with the first handle 2, and configured to move closer to or further away from the tester body 1; a fixed rod 4, one end of which is installed on the tester body 1, with the second handle 3 mounted on the fixed rod 4, providing stable support for the second handle 3 and a cleaning head 6, ensuring the stability and accuracy of the testing process; and a cleaning head 6, connected to one end of the fixed rod 4, configured to rotate on the fixed rod 4 when the fixed rod 4 moves on the second handle 3, for cleaning dust inside the test hole, effectively cleaning dust inside the test hole, improving the accuracy and reliability of the test.

[0027] The second handle 3 includes: a through hole 304, located at one end of the second handle 3, with the fixing rod 4 and cleaning head 6 both disposed within the through hole 304, providing installation space for the fixing rod 4 and cleaning head 6, ensuring they can be stably mounted on the second handle 3 and move and rotate smoothly; a washer 301, installed at one end of the second handle 3, increasing the contact stability between the second handle 3 and the building wall; two air holes 303, located on the inner wall of the through hole 304 and extending from one end of the second handle 3, used to blow air into the measuring hole to further clean dust and improve the clarity of the detection; and two airbags 305, installed... At one end of the second handle 3, two airbags 305 are connected to two air holes 303 respectively. When the airbags 305 are squeezed, they blow air into the air holes 303, providing the airflow required for cleaning dust and enhancing the cleaning effect. One end of the elastic element 302 is installed on the detector body 1, and the other end is installed on the second handle 3. The elastic element 302 is used to provide the second handle 3 with the restoring force of the initial position, so that the detector can automatically return to the initial state after use, improving the convenience and efficiency of use. The elastic element 302 is made of stainless steel spring, or it can be made of elastic rubber block.

[0028] A rotating rod 5 is mounted on a fixed rod 4 and disposed within a through hole 304. A cleaning head 6 is mounted on the rotating rod 5. The rotating rod 5 is configured to rotate on the fixed rod 4 to drive the cleaning head 6 to rotate, thereby improving the dust removal effect and efficiency. The rotating rod 5 includes a movable groove 501, which is formed on the rotating rod 5. A fixed block 306 is installed on the inner wall of the through hole 304 and is connected to the movable groove 501. The movable groove 501 is spiral-shaped. When the fixed rod 4 is pushed, the fixed rod 4 moves within the through hole 304 and causes the rotating rod 5 to move. During the displacement of the rotating rod 5, since the movable groove 501 is connected to the fixed block 306 and the movable groove 501 is spiral-shaped, the fixed block 306 can restrict the movement position of the rotating rod 5, allowing the rotating rod 5 to rotate under the restriction of the fixed block 306.

[0029] The cleaning head 6 has several protrusions 601, which are used to clean the dust in the test hole, thereby improving the thoroughness of cleaning and the accuracy of detection.

[0030] During use, after the measuring nail is driven into the mortar using the measuring instrument body 1, a certain amount of dust is often generated in the measuring hole. Align one end of the second handle 3 with the measuring hole to be cleaned, and prepare to start cleaning the dust. Push the measuring instrument body 1; the washer 301 on the second handle 3 adheres to the building wall and cannot move further. The measuring instrument body 1 moves closer to the second handle 3, and the fixing rod 4 moves within the through hole 304. Simultaneously, the second handle 3 compresses the elastic element 302, causing it to deform. The movement of the fixing rod 4 drives the rotating rod 5 to shift. Due to the movement groove 501 and the fixing block 306 on the inner wall of the through hole 304... The connection is made so that the moving groove 501 is spiral-shaped. Therefore, the rotating rod 5 rotates under the restriction of the fixed block 306. This causes the rotating rod 5 to drive the cleaning head 6 to penetrate into the test hole. At the same time, the rotation of the rotating rod 5 drives the cleaning head 6 to rotate on the fixed rod 4. Several protrusions 601 on the cleaning head 6 begin to clean the dust in the test hole. At the same time, the second handle 3 also squeezes the air bag 305 to blow air into the air blowing hole 303. The air blowing hole 303 blows the gas into the test hole through the through hole 304 to clean the dust in the test hole. After the dust is cleaned, the detection part of the detector body 1 is aligned with the test hole to start detecting the mortar strength.

[0031] In summary, compared with existing technologies, it has the following beneficial effects:

[0032] By introducing the design of the rotating rod 5 and the cleaning head 6, the rotational movement of the cleaning head 6 is realized when it moves on the fixed rod 4, which effectively improves the cleaning effect of dust in the test hole. The several protrusions 601 on the cleaning head 6 can clean the dust more thoroughly, reduce the impact of dust on the detection accuracy, and improve the accuracy and reliability of mortar strength detection.

[0033] The spiral moving groove 501 of the rotating rod 5 cooperates with the fixed block 306 on the inner wall of the through hole 304, so that when the fixed rod 4 is pushed, the rotating rod 5 can rotate automatically, driving the cleaning head 6 to rotate, improving the efficiency of dust cleaning and shortening the detection preparation time.
