Technical Field
[0001] The utility model relates to the technical field of construction engineering, in particular to a knocking hammer for construction engineering quality supervision and inspection. Background Technique
[0002] At present, the tools for construction engineering quality supervision and inspection in the prior art generally use a hollowing hammer. Workers use the hollowing hammer to slide or knock on the wall surface, and judge whether there is a hollowing condition in this area by the different timbres of the sound feedback from the wall surface, etc. If there is a problem, mark it and reconstruct it.
[0003] When the inspector uses a traditional knocking hammer to detect the hollowing of high - altitude tiles, if it is found that the tiles are hollow, the traditional knocking hammer cannot perform the operation of marking the hollow position. When marking, the inspector needs to take an additional marking pen for marking, which is more inconvenient to operate. Therefore, in order to solve the above problems, this device proposes a knocking hammer for construction engineering quality supervision and inspection. Content of the Utility Model

[0022] Embodiment 1
[0023] Referring to the attached Figures 1-4 , a knocking hammer for building engineering quality supervision and inspection proposed by the present utility model includes a mounting frame 10 and a knocking head 20. The knocking head 20 is fixedly installed on the end wall of the mounting frame 10. An adjusting telescopic rod 40 is fixedly installed on the outer wall of the mounting frame 10. An installation groove 21 is opened inside the knocking head 20, and a marking pen 30 is movably installed inside the installation groove 21. Among them, by installing the marking pen 30 on the knocking hammer, it is convenient for the staff to mark the position of the hollow drum.
[0024] A fixing mechanism is arranged on the mounting frame 10. The fixing mechanism is used to fix the marking pen 30. The fixing mechanism includes two fixing ring frames 51. The two fixing ring frames 51 are connected and fixed together by a connecting rod 53. A slider 54 is fixedly installed on the bottom wall of the connecting rod 53. A sliding groove 55 is opened on the inner wall of the mounting frame 10. The outer wall of the slider 54 is slidably connected to the inner wall of the sliding groove 55. The marking pen 30 is detachably installed inside the fixing ring frame 51. Thread grooves are symmetrically opened on the side wall of the fixing ring frame 51, and a locking screw 52 is threadedly connected to the inner wall of the thread groove. The locking screw 52 is used to lock and fix the marking pen 30. Among them, the marking pen 30 can be disassembled, which is convenient for replacement. When disassembling, the locking screw 52 can be rotated counterclockwise to release the fixing of the locking screw 52 on the marking pen 30, and then the marking pen 30 can be pulled out from the fixing ring frame 51 to complete the disassembly of the marking pen 30.
[0025] A moving mechanism is arranged outside the adjusting telescopic rod 40. The moving mechanism is used to drive the slider 54 to move. The moving mechanism includes a pull rope 61 fixedly connected to the side wall of the slider 54. A through groove 62 communicating with the inside of the sliding groove 55 is opened on the side wall of the mounting frame 10. One end of the pull rope 61 away from the slider 54 movably penetrates through the through groove 62 and extends to the bottom end position of the adjusting telescopic rod 40. Among them, the position of the marking pen 30 can be adjusted by moving. When moving the marking pen 30 so that the writing end of the marking pen 30 moves out of the knocking head 20, the pull rope 61 can be pulled. The pull rope 61 drives the slider 54 to move. The slider 54 drives the connecting rod 53 and the fixing ring frame 51 to move, thereby driving the marking pen 30 to move.
[0026] A spring 63 is sleeved outside the side of the drawstring 61 close to the slider 54. One end of the spring 63 is fixedly connected to the outer wall of the slider 54, and the other end of the spring 63 is fixedly connected to the inner wall of the chute 55. Among them, when the marker pen 30 is no longer in use, the marker pen 30 can be movably retracted into the interior of the percussion head 20. That is, when the pulling of the drawstring 61 is released, under the action of the elastic potential energy of the spring 63, the slider 54 can move to the side away from the percussion head 20, thereby driving the marker pen 30 to retract into the interior of the percussion head 20.
[0027] A limit ring 64 is fixedly installed on the outer wall of the adjustable telescopic rod 40, and the drawstring 61 movably passes through the interior of the limit ring 64. Among them, the limit ring 64 is installed on the outer wall of the lowermost sleeve of the adjustable telescopic rod 40. By providing the limit ring 64, the drawstring 61 can be restricted, improving the neatness of the drawstring 61.
[0028] In this embodiment, the working principle of the device is as follows: When using the device to detect the quality of whether the wall tiles are hollow, the tester can hold the adjustable telescopic rod 40 and then use the percussion head 20 to strike the position to be detected.
[0029] When a hollow position is detected, the drawstring 61 can be pulled with the other hand. The drawstring 61 drives the writing end of the marker pen 30 to move out of the installation groove 21 on the side wall of the percussion head 20, so that the hollow position can be marked with the marker pen 30. There is no need for the staff to look for and take the marker pen, improving the detection efficiency.
[0030] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
