When the hollow hammer is needed, the hollow hammer is driven to slide outside the first cavity, and the telescopic mechanism is fixed by the fixing mechanism, thereby ensuring the stability of the hollow hammer when working and the stability of the hollow hammer when stored.

[0035] The embodiment of the present application discloses a construction engineering inspection ruler.

[0036] like Figure 1 and Figure 2 As shown, the construction engineering inspection ruler includes a first inspection ruler 1, a hollow hammer 2, a telescopic mechanism 3, a fixing mechanism 4, a second inspection ruler 5 and a horizontal bubble meter 6. A first cavity 11a is provided in the first inspection ruler 1, and the first cavity 11a is preferably set as a rectangular cavity. The telescopic mechanism 3 is installed in the first cavity 11a, and the hollow hammer 2 is connected to the telescopic mechanism 3. A slide groove is provided on the inner wall of the first cavity 11a, and the fixing mechanism 4 is connected to the telescopic mechanism 3 through the slide groove. The second inspection ruler 5 is hinged to the first inspection ruler 1 through a connecting shaft, and the connecting shaft is preferably set as a rotating shaft with a damping ring. A handle 7 is installed on the connecting shaft for the operator to hold during measurement, and the second inspection ruler 5 can be rotated relative to the first inspection ruler 1, so that the side wall of the second inspection ruler 5 fits with the side wall of the first inspection ruler 1, reducing the space occupied by it. There are two horizontal bubble meters 6, and the two horizontal bubble meters 6 are respectively installed at the middle part of the first inspection ruler 1 and the second inspection ruler 5.

[0037] like Figure 3 , Figure 4 and Figure 5 As shown, the telescopic mechanism 3 includes a telescopic spring 31, a slider 32 and a positioning rod 33. The slider 32 is slidably connected in the first cavity 11a. The slider 32 is preferably provided with a rectangular block. One end of the telescopic spring 31 is fixedly connected to the inner wall of the first cavity 11a, and the other end of the telescopic spring 31 is fixedly connected to the slider 32. A heart-shaped annular groove 321 is provided on the slider 32. One end of the positioning rod 33 is hinged on the inner wall of the first cavity 11a, and a columnar block 34 is welded to the other end of the positioning rod 33. The columnar block 34 is slidably connected in the heart-shaped annular groove 321, and the hollow drum hammer 2 is fixedly connected to the end of the slider 32 away from the telescopic spring 31.

[0038] The outer wall of the heart-shaped annular groove 321 is formed with bends e14, f15, g16 and h17, and the inner wall of the heart-shaped annular groove 321 is formed with bends a10, b11, c12 and d13.

On the left side of the bend b11, the columnar block 34 is ensured to slide along the side wall of the heart-shaped hole to the outer wall of the heart-shaped annular groove 321 between the bend e14 and the bend f15. When the pressing force on the slider 32 is released, the telescopic spring 31 pushes the slider 32 to move, and the columnar block 34 is pressed against the line segment connecting the bend a10 and the bend b11, and is slidably engaged at the bend b11 to store the hollow drum hammer 2.

[0039] The projection of the bend g16 on the inner wall of the heart-shaped annular groove 321 is located on the right side of the bend c12, and the projection of the bend h17 on the inner wall of the heart-shaped annular groove 321 is located on the right side of the bend d13. When the hollow drum hammer 2 needs to slide out of the first cavity 11a, the slider 32 is pressed, and the columnar block 34 is pressed against the line segment connecting the bend f15 and the bend g16, and slides along the outer wall of the heart-shaped annular groove 321 until it is clamped on the bend. At h17, when it is necessary to store the hollow hammer 2 in the first cavity 11a again, press the slider 32, and the columnar block 34 presses against the inner wall of the heart-shaped ring groove 321 on the left side of the bend d13, and after sliding along the inner wall of the heart-shaped ring groove 321, presses against the outer wall of the heart-shaped ring groove 321 between the bend e14 and the bend f15, until the columnar block 34 is clamped at the bend b11 again to store the hollow hammer 2.

[0040] like Figure 4As shown, the fixing mechanism 4 includes a threaded rod 41 and a positioning plate 42. A threaded hole is opened on the slider 32 corresponding to the threaded rod 41. The threaded rod 41 passes through the slide groove and is threadedly connected in the threaded hole. The positioning plate 42 is coaxially welded to the threaded rod 41. A rubber pad 43 is fixedly connected to the side wall of the positioning plate 42 adjacent to the slider 32, which can increase the friction between the positioning plate 42 and the side wall of the first detection ruler 1.

[0041] like Figure 3 and Figure 6 As shown, in the embodiment of the present application, a winding mechanism 8 and a plumb bob 9 are also included. A second cavity 51 is opened in the second detection ruler 5. The second cavity 51 is set as a cylindrical cavity corresponding to the plumb bob 9 and is set through the opening of the side wall of the second detection ruler 5. The winding mechanism 8 includes a rotating rod 81, a winding gear 83, an auxiliary gear 84 and a winding roller 85. The winding roller 85 is rotatably connected in the second cavity 51. One end of the rotating rod 81 passes through the side wall of the second detection ruler 5 and extends into the second cavity 51. An anti-slip round cap 82 is fixed on one end of the rotating rod 81 arranged outside the second cavity 51 to facilitate the operator to rotate the rotating rod 81. The winding gear 83 is coaxially arranged at one end of the rotating rod 81 extending to the second cavity 51. The auxiliary gear 84 is coaxially arranged on the winding roller 85. The winding gear 83 is meshed with the auxiliary gear 84. The plumb bob 9 is slidably connected in the second cavity 51 and is connected to the winding roller 85 through a wire group. When the plumb bob 9 is needed, the rotating rod 81 is rotated, the rotating rod 81 drives the winding gear 83, the winding gear 83 drives the auxiliary gear 84, and the auxiliary gear 84 drives the winding roller 85 to rotate, thereby unwinding the line group, and rotating the second detection ruler 5, so that the plumb bob 9 slides out of the second cavity 51 under the influence of gravity, and the verticality detection can be performed by the plumb bob 9.

[0042] The implementation principle of a construction engineering inspection ruler in the embodiment of the present application is as follows: when the first inspection ruler 1 does not measure enough length, the second inspection ruler 5 is rotated so that the first inspection ruler 1 and the second inspection ruler 5 are arranged on a straight line, thereby increasing the range of the measuring length; when the hollow drum hammer 2 is needed, the threaded rod 41 is pushed to drive the slider 32 to move and squeeze the telescopic spring 31, the columnar block 34 slides in the heart-shaped groove, the telescopic spring 31 is extended and pushed out of the slider 32, the slider 32 drives the hollow drum hammer 2 to pass through the first cavity 11a, and then the threaded rod 41 is screwed into the slider 32. The positioning plate 42 is pressed against the side wall of the first detection ruler 1 to fix the slider 32, thereby ensuring the stability of the hollow drum hammer 2 when in use and preventing the hollow drum hammer 2 from vibrating under the action of the spring, which would affect the normal use of the hollow drum hammer 2. When the plumb bob 9 needs to be used to measure the verticality, the anti-slip round cap 82 is rotated to drive the rotating rod 81, the rotating rod 81 drives the winding gear 83 to rotate, the winding gear 83 drives the auxiliary gear 84, and the auxiliary gear 84 drives the winding roller 85 to unwind the wire group, so that the plumb bob 9 can be poured out of the second cavity 51 for use under the influence of its own weight.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
