Technical Field

[0001] This utility model relates to the field of building quality testing technology, and more specifically, to a quality testing device for building construction supervision. Background Technology

[0002] The quality inspection equipment for building construction supervision includes multiple inspection devices. Among them, the compressive strength of the walls in building construction can be tested by a rebound hammer. The main process is to align the detection head of the rebound hammer with the wall or position to be tested, and then press it so that the detection head retracts into the housing. The compressive strength of the current test position is then displayed on the screen.

[0003] A search revealed a building quality testing instrument with authorization announcement number CN216955568U. This application can provide comprehensive protection for the impact rod at the front end of the rebound hammer, preventing damage and improving testing accuracy.

[0004] In existing technologies, the verticality of a rebound hammer is usually determined by visual inspection while holding it by hand, but this method is prone to tilting and can lead to inaccurate testing. Therefore, we have made improvements and proposed a quality inspection device for building construction supervision. Summary of the Invention

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0025] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely illustrates some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model. It should be noted that, unless otherwise specified, the embodiments, features, and technical solutions in the embodiments of this utility model can be combined with each other.

[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0027] like Figure 1-4 As shown, this embodiment proposes a quality inspection device for building construction supervision, including an outer shell 1. One end of the outer shell 1 is connected to a detection head 2. An alignment structure 3 is provided on the outer surface of the outer shell 1 near the detection head 2. The alignment structure 3 includes a guide groove 31 opened on one end surface of the outer shell 1. A push spring 32 is provided inside the guide groove 31. One end of the push spring 32 is connected to a guide rod 33. One end of the guide rod 33 is fixedly connected to a positioning ring 34.

[0028] An annular groove 35 is provided on the outer surface of the outer shell 1. A rotating ring 36 is rotatably connected to the inner side of the outer shell 1 corresponding to the annular groove 35. A first magnetic block 37 is fixedly connected to the outer surface of the rotating ring 36. A second magnetic block 38 is fixedly connected to the inner side of the outer shell 1. A locking block 39 is fixedly connected to the inner side of the rotating ring 36. A locking groove 310 is provided on the outer surface of the guide rod 33. A protruding ring 311 is fixedly connected to the outer surface of the rotating ring 36.

[0029] A display screen 4 for displaying test results is fixedly connected to the outer surface of the outer casing 1, and buttons 5 for adjusting test parameters are also fixedly connected to the outer surface of the outer casing 1.

[0030] The guide rod 33 slides back and forth along the length of the guide groove 31. The elastic ends of the guide groove 31 are fixedly connected to the guide rod 33 and the outer shell 1, respectively. A set of positioning rings 34 corresponds to several sets of guide rods 33 and are distributed in a ring array.

[0031] The rotating ring 36 and the convex ring 311 are rotatably connected to the outer shell 1. The card block 39 matches the card slot 310. The number of the first magnetic block 37 is several groups and is distributed in a ring array. The number of the second magnetic block 38 is half the number of the first magnetic block 37 and is distributed in a ring array.

[0032] The second magnetic block 38 and the first magnetic block 37 are magnetically connected. The rotation adjustment block 39 of the rotating ring 36 is inserted into or removed from the slot 310 on the surface of the guide rod 33. The positioning of the rotating ring 36 and the first magnetic block 37 is achieved by the mutual attraction between the first magnetic block 37 and the second magnetic block 38.

[0033] By aligning the structure 3, when inspecting locations such as building walls, it can be ensured that the inspection head 2 and the outer shell 1 remain perpendicular to the wall during inspection. This results in more accurate inspection. Additionally, the positioning ring 34 and the guide rod 33 can be fixed in position or have retractable properties according to the user's actual needs.

[0034] In summary, the working principle of this utility model is as follows:

[0035] During use, the user can hold the outer shell 1 with one hand and then rotate the rotating ring 36 so that the adjacent first magnetic block 37 is attracted to the second magnetic block 38. During this process, the card block 39 is disengaged from the card slot 310. Then, the user can hold the outer shell 1 with both hands and align one end of the detection head 2 with the wall position to be detected, while making the positioning ring 34 fit against the wall. At this time, push the outer shell 1 towards the detection head 2 side, and the detection head 2 gradually retracts into the interior of the outer shell 1 until the root of the outer shell 1 retracts to the surface of the outer shell 1. At this time, the display screen 4 will display the detection result, completing one rebound value detection.

[0036] During the rebound detection process, the guide rod 33 will push the push spring 32 to contract, so that the surface of the positioning ring 34 is always flush with the surface of the detection head 2. After the detection is completed, the reaction force of the push spring 32 can push the positioning ring 34 back to its original position. When it returns to its original position and the detection device is not to be used, the rotating ring 36 can be rotated to keep the adjacent first magnetic block 37 and second magnetic block 38 stable under the attraction force. At this time, the locking block 39 is just embedded in the locking groove 310 on the surface of the guide rod 33. At this time, the guide rod 33 cannot slide back and forth along the direction of the guide groove 31. At the same time, through the action of the positioning ring 34 and the guide rod 33, the detection head 2 can be protected when the building wall is not being tested, and the effect of use is better.

[0037] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
