Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hollow sound hammers, in particular to an engineering management detection hollow sound hammer. Background Technique
[0002] The hollow sound hammer used in engineering management detection is a tool specifically used to detect whether there is a hollow phenomenon on the walls, floors, etc. of buildings. The hollow phenomenon refers to the air layer existing between the surface of the building and the base layer, which may cause the surface material to be unstable and easy to fall off, affecting the building quality and use safety.
[0003] The use method of the hollow sound hammer is relatively simple. The detector uses the hollow sound hammer to gently tap the surface of the building, and judges whether there is a hollow by listening to the sound and feeling the vibration. If the tapping sound is clear and the vibration feeling is obvious, then there may be a hollow at that part. On the contrary, if the sound is dull and the vibration feeling is weak, it may indicate that there is no hollow or the degree of hollow is relatively light at that part. In engineering management detection, the use of the hollow sound hammer is of great significance. It can help the detector timely discover and handle the hollow problem, and avoid quality problems or safety hazards during the use of the building. At the same time, the use of the hollow sound hammer is also an important part of engineering quality management, which helps to ensure the overall quality and use performance of the building.
[0004] However, most of the existing hollow sound hammers have a fixed length. The hollow sound hammer with a fixed length may not be able to adapt to all detection scenarios. In some narrow or hard-to-reach spaces, the too-long hollow sound hammer may be difficult to operate and even unable to reach the area to be detected; while on some large-area or flat surfaces, the too-short hollow sound hammer may reduce the detection effect due to the dispersion of force. At the same time, when the staff stores the hollow sound hammer, it is easy to occupy a large amount of storage space and is too troublesome. Therefore, the present utility model is proposed to solve the above problems. Content of the Utility Model

[0020] Please refer to Figure 1 , a kind of engineering management inspection hollow drum hammer in this embodiment, including an outer cylinder 1, a fixed cylinder 2 is fixedly installed on the lower surface of the outer cylinder 1. The interiors of both the outer cylinder 1 and the fixed cylinder 2 are hollow structures, and the top and bottom of the fixed cylinder 2 are open structures. A telescopic assembly extending into the fixed cylinder 2 is arranged inside the outer cylinder 1
[0021] It should be noted that a bearing 9 is fixedly installed on the lower surface of the outer cylinder 1, and the fixed cylinder 2 is fixedly installed on the inner wall of the bearing 9. The top of the fixed cylinder 2 is rotationally connected to the lower surface of the outer cylinder 1 through the bearing 9
[0022] Please refer to Figure 1 , Figure 2 and Figure 3 , in this embodiment, a fixing member is further arranged inside the telescopic assembly. The other end of the fixing member extends to a connecting member inside the fixed cylinder 2, and a limiting member is arranged at one end of the fixing member located inside the fixed cylinder 2
[0023] Among them, the fixing member includes a threaded cylinder 3 fixedly installed between the inner bottom wall and the inner top wall of the outer cylinder 1. A connecting rod 4 with the other end fixedly connected to the inner wall of the outer cylinder 1 is fixedly installed on the outer surface of the threaded cylinder 3.

The threaded rod 5 is limited by the sliders 8, so that the threaded rod 5 can move vertically stably.
[0026] When the staff needs to adjust the length of the hollow drum hammer 7, one hand of the staff holds the outer cylinder 1, and the other hand holds the fixed cylinder 2, and rotates the outer cylinder 1 forcefully, so that the outer cylinder 1 drives the threaded cylinder 3 to rotate, so that the threaded cylinder 3 can drive the threaded rod 5 to move vertically, thereby driving the hollow drum hammer 7 to move through the positioning plate 6, so as to adjust the length of the hollow drum hammer 7 exposed outside the fixed cylinder 2, so that the staff can adjust the length of the hollow drum hammer 7 according to the on-site requirements.

[0029] The working principle of the above embodiment is: when the staff needs to adjust the length of the hollow drum hammer 7, one hand of the staff holds the outer cylinder 1, and the other hand holds the fixed cylinder 2, and rotates the outer cylinder 1 forcefully, so that the outer cylinder 1 drives the threaded cylinder 3 to rotate, so that the threaded cylinder 3 can drive the threaded rod 5 to move vertically, thereby driving the hollow drum hammer 7 to move through the positioning plate 6, so as to adjust the length of the hollow drum hammer 7 exposed outside the fixed cylinder 2, so that the staff can adjust the length of the hollow drum hammer 7 according to the on-site requirements. And when the staff needs to store it, the staff can retract the hollow drum hammer 7 into the fixed cylinder 2, thus saving storage space.
