Hollow drum hammer head: generally a solid ball, made of stainless steel and other metal materials, connected with the shaft by means of threads, etc., sturdy and durable, not easy to fall off, can ensure the accuracy and stability of detection.
The surface of the handle is usually wrapped with sponge and other materials, which is not only comfortable to hold, but also has the effect of anti-slip and shockproof, which can reduce the fatigue and discomfort of the hand during long-term use, and the suspension device: generally located at the end of the handle, some are a lanyard hole, and some are equipped with an anti-off lanyard, which is convenient for hanging the hollow drum hammer on the wrist or on the tool holder to prevent falling and hurting or losing during use.
The hammer head of some hollow drum hammers can also be rotated for easy inspection from different angles. Handle: Most of them are telescopic structure, which is convenient for the operator to flexibly adjust the length according to the height and position of the detection part. The material is often made of thickened copper pipe or aluminum alloy, which not only ensures a certain strength, but also does not be too bulky.
The working principle of the hollow drum hammer: the hammer is used to hit the surface to be detected, so that the wall or the ground produces vibration and sound, due to the different structure of the hollow drum part and the solid part, the way the sound propagates and reflects in it are also different. If the tap is on a solid part, the sound is usually crisp and loud; In the case of a hollow drum, the sound will appear low and hollow, similar to the "Dongdong" sound, and the presence of a hollow drum can be determined by identifying the change in this sound.
The function of the wall detection hammer: It is mainly used in scenarios such as building construction, decoration acceptance and daily inspection of houses, and can help professionals or owners find hollow drum problems on walls, floor tiles, ceilings and other parts in time. In order to repair the hollow drum part before decoration or occupancy, avoid problems such as cracking of the wall and floor and falling off of tiles due to hollowing in the later stage, and ensure the quality and safety of the building. How to use: First check the integrity of the hollow drum hammer to make sure that there is no damage to the hammer head, handle and suspension device. Then the suspension device of the hollow drum hammer is fixed above the detection part to ensure that the hollow drum hammer hangs vertically. Gently tap the wall or floor surface with a hammer, pay attention to the moderate force, too light may cause missed detection, too heavy may damage the surface to be measured. Finally, observe the vibration and listen carefully to the sound, judge whether there is a hollow drum according to the characteristics of the sound, and judge the scope and severity of the hollow drum based on experience.
