Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of engineering quality testing, specifically a hammer for supervising and testing the quality of building engineering. Background Technology
[0002] In the quality supervision and inspection of building construction projects, the detection of hollow spots in decorative surfaces such as ceramic tiles is an important aspect. Currently, the commonly used testing tool is a hammer. Inspectors use the hammer to tap the surface of the tile and judge whether there are hollow spots based on the sound produced.
[0003] However, existing hammers, when used with marking components, can mark the location of hollow areas after detection. But existing hammers have structural design deficiencies. The marking components cannot be used in conjunction with the hammer during use and are easily damaged when not in use, shortening the tool's lifespan.
[0004] Therefore, those skilled in the art have provided a hammer for quality supervision and testing in construction engineering to solve the problems mentioned above. Utility Model Content
[0005] To address the aforementioned problems, this utility model provides a hammer for quality supervision and inspection in construction engineering.
[0006] To achieve the above objectives, the technical solution of this utility model is as follows:
[0007] A hammer for quality supervision and inspection in construction engineering, comprising:
[0008] The hammer body has large and small balls of different diameters at both ends;
[0009] A slot is provided on the hammer body;
[0010] The bayonet is located on the side of the hammer body and intersects with the slot opening;
[0011] The hammer handle is inserted into the slot and can rotate along the central axis of the slot.
[0012] A locking block is fixed to one end of the hammer handle;
[0013] A marking block is fixedly installed on the side of the card block away from the hammer handle for marking purposes;
[0014] A spring, sleeved on the hammer handle, presses the hammer body to make the locking block engage with the locking groove or locking slot.
[0015] When the card block engages with the card slot, the marking block is located on the side of the hammer body near the common tangent of the large ball and the small ball facing away from the hammer handle; when the card block engages with the bayonet, the drawing area of the marking block is partially or entirely located on the side of the common tangent away from the hammer handle.
[0016] Preferably, the card slot and the card opening are perpendicularly intersecting, the card block is adapted to the card slot, and the width of the card slot is equal to the width of the card opening and the width of the card slot is equal to the width of the card block.
[0017] Preferably, the marker block is located at the center of the card block, and the drawing area of the marker block is set as a hemispherical surface.
[0018] Preferably, the end of the slot facing the hammer handle is cylindrical, and the end of the hammer handle near the locking block is also cylindrical with the same diameter.
[0019] Preferably, the hammer handle is perpendicular to the hammer body, and the locking block is located at the center of gravity of the hammer body.
[0020] In summary, this utility model has the following beneficial technical effects:
[0021] 1. When the card block and the card slot are engaged, the marking block is in an unused state. When the whole block is placed on a flat surface, the large ball and the small ball will touch the ground first, which can protect the marking block and prevent it from being worn or damaged due to direct contact with the flat surface.
[0022] 2. When the card block and the jaw are engaged, the large ball and the small ball act as the center to draw circles, which can draw circles of different diameters, making it easy to quickly see the size of the void without the need for additional marking tools, thus improving the efficiency of the detection mark.

[0029] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.
[0030] A hammer for quality supervision and testing in construction projects, referring to Figure 1-4 ,include:
[0031] The hammer body 1 has a large ball and a small ball of different diameters at both ends. The large and small balls can be used to tap and detect tiles in different areas, and the hollowness can be judged by the difference in sound. This dual-ball design can adapt to tile areas of different sizes. For example, the small ball can be used flexibly to tap small areas such as corners, while the large ball is suitable for detecting large areas of tiles, which improves the versatility and detection efficiency of the tool.
[0032] The slot 11 is formed on the hammer body 1; the opening 12 is located on the side of the hammer body 1 and intersects with the opening of the slot 11.
[0033] The hammer handle 2 is inserted into the slot 11 and can rotate along the central axis of the slot 11.
[0034] The locking block 21 is fixed to one end of the hammer handle 2. The locking block 21 can be engaged with the slot 11 or the bayonet 12 to ensure the stable fixation of the hammer handle 2 in different functional states and prevent shaking during operation.
[0035] Marker block 3 is fixedly installed on the side of card block 21 away from hammer handle 2, and is used to mark hollow tiles.
[0036] Spring 4 is sleeved on hammer handle 2 and presses hammer body 1 to make the locking block 21 engage with the locking groove 11 or the locking opening 12 to ensure the stability of the engagement.
[0037] By pressing the large or small ball against the hammer body 1 and squeezing the hammer handle 2 towards it, and then rotating it at a certain angle, the locking block 21 can switch between the slot 11 and the jaw 12, realizing the conversion between different functional states. The switching method is simple and efficient, allowing operators to quickly switch between tapping detection and hollow drum marking, thus improving the work rhythm.
[0038] When the card block 21 is engaged with the card slot 11, the marking block 3 is located on the side of the common tangent of the large ball and the small ball facing away from the hammer handle 2, close to the hammer body 1. When the marking block 3 is in an unused state and is placed on a flat surface, the large ball and the small ball will touch the ground first, which can protect the marking block 3 and prevent the marking block 3 from being worn or damaged due to direct contact with the flat surface.
[0039] When the locking block 21 engages with the locking slot 12, the drawing area of the marking block 3 is partially or entirely located on the side of the common tangential plane away from the hammer handle 2. The large and small balls serve as the center for drawing circles, allowing circles of different diameters to be drawn, making it easy to quickly determine the size of the void without the need for additional marking tools, thus improving the efficiency of the detection markings. Using the large and small balls as the center for drawing circles does not affect the overall rotation, resulting in low friction.
[0040] The card slot 11 and the bayonet opening 12 are perpendicularly intersecting, and the card block 21 is adapted to the card slot 11. The width of the card slot 11 is equal to the width of the bayonet opening 12, and the width of the card slot 11 is equal to the width of the card block 21. This structural design ensures the smoothness and stability of the card block 21 when switching between the card slot 11 and the bayonet opening 12, avoiding jamming or loosening.
[0041] Marker block 3 is located at the center of card block 21, and the drawing area of marker block 3 is set as a hemispherical surface. The hemispherical drawing area makes more stable contact with the tile surface during marking, resulting in better marking effect, and also reduces the wear of marker block 3 itself.
[0042] The end of the slot 11 facing the hammer handle 2 is cylindrical, and the end of the hammer handle 2 near the locking block 21 is also cylindrical with the same diameter. The cylindrical design makes the rotation of the hammer handle 2 within the slot 11 more flexible, reduces frictional resistance during rotation, and facilitates function switching operations for the operator.
[0043] The hammer handle 2 is perpendicular to the hammer body 1, and the locking block 21 is located at the center of gravity of the hammer body 1. This structural design makes the center of gravity of the entire hammer stable, making it easier and more convenient for the operator to use, while also improving the accuracy of the striking test.
[0044] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
