Description

Technical Field

[0001] This utility model belongs to the field of hollow wall detection technology, and more specifically, it relates to a wall hollow wall detection device. Background Technology

[0002] Hollow spots in walls are caused by poor adhesion between the base layer and the surface decorative layer, resulting in air pockets. Tapping on these pockets produces a clear, hollow sound. Hollow spots can damage the wall's decorative layer, affect aesthetics, and pose a risk of falling debris and injury. They can also lead to moisture leakage, weaken insulation and soundproofing, and compromise structural stability. A hollow spot detection hammer can quickly and accurately locate hollow spots, preventing wall damage and structural problems. However, traditional hollow spot detection hammers only have a tapping function and require various components for detection. This increases the workload for inspectors, increases the risk of missing tools, and makes the coordinated use of each component cumbersome, thus affecting detection efficiency. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a wall hollow detection device. This addresses the issues in the prior art where traditional hollow detection hammers have limited functionality, require multiple auxiliary components, increase the burden on testing personnel, are prone to tool omissions, and involve cumbersome multi-component collaborative operation, thus affecting testing efficiency.

[0004] The purpose and effectiveness of this utility model's wall hollow detection device are achieved through the following specific technical means:

[0005] A wall hollowing detection device includes a handle with mounting grooves and assembly grooves at both ends. A telescopic rod is detachably mounted in the mounting groove, and a mounting component is mounted at the top of the telescopic rod. The mounting component has a hollow structure, and different types of hammers are replaceably mounted on both sides of the mounting component. An assembly component is detachably mounted in the assembly groove. The handle also has a storage cavity, and a marker pen is inserted into the storage cavity. One end of the marker pen is detachably attached to the assembly component. A battery compartment is located at the other end of the assembly component away from the handle. The battery compartment has a cover and a light. A battery block is located between the cover and the battery compartment. A switch is located on the battery compartment, and the two ends of the switch are electrically connected to the battery block and the light, respectively.

[0006] The above technical solution further includes that the end of the telescopic rod near the handle is provided with a connector with external threads, and the telescopic rod is detachably connected to the handle through the connector.

[0007] The above technical solution further includes that the grip bar is also fitted with a sponge-material gripping component.

[0008] The above technical solution further includes that each of the two sets of striking hammers has a mounting part on one of its opposite sides, and the two sets of striking hammers are respectively replaceably fastened to both sides of the mounting part through the mounting part.

[0009] The above technical solution further includes that a magnetic block is provided at the top of the assembly, and the assembly contacts the bottom of the grip rod through the magnetic block.

[0010] The above technical solution further includes that a slot is provided at one end of the assembly near the storage cavity, and the bottom end of the marker is detachably locked in the slot.

[0011] The above technical solution further includes that a sealing element is provided at one end of the cover near the battery compartment, and the sealing element is in contact with the battery compartment.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model. Example

[0022] like Figures 1 to 4 As shown, this utility model provides a wall hollow detection device, including a handle 1. The handle 1 has an installation groove and an assembly groove at both ends. A telescopic rod 2 is detachably installed in the installation groove. An installation component 101 is also provided at the top of the telescopic rod 2. The installation component 101 has a hollow structure, and different types of hammers 3 are replaceably mounted on both sides of the installation component 101. An assembly component 102 is detachably installed in the assembly groove. A storage cavity is also provided inside the handle 1. The assembly also includes a marker pen 4, one end of which is detachably attached to the assembly 102. A battery compartment 103 is located at the other end of the assembly 102 away from the handle 1, with a cover 104 on the battery compartment 103 and a light 5 on the cover 104. A battery block 6 is located between the cover 104 and the battery compartment 103, and a switch 105 is located on the battery compartment 103. The two ends of the switch 105 are electrically connected to the battery block 6 and the light 5, respectively. The handle 1 has differentiated mounting slots and assembly slots at both ends. The mounting slots are adapted for the detachable installation of the telescopic rod 2. The mounting component 101 at the top of the telescopic rod 2 is hollow, allowing for quick replacement of different types of hammers 3 on both sides of the mounting component 101, enabling testing of walls of different materials and thicknesses. The assembly slot is used to install the assembly component 102, on which a battery compartment 103, a cover 104, and a light 5 are configured to form a lighting assembly. Meanwhile, a marker pen 4 is installed through the internal storage cavity of the handle 1, with one end of the marker pen 4 connected to the assembly component 102. The entire device integrates three functions: wall tapping detection, hollow area marking, and ambient lighting. Inspectors do not need to carry additional tapping tools, marking tools, or lighting tools.

[0023] The telescopic rod 2 connects to the handle 1 via an end structure, enabling length adjustment and quick assembly / disassembly to adapt to the inspection needs of walls of different heights. The mounting piece 101 has symmetrical snap-fit ​​positions on both sides; pressing the hammer 3 allows for easy model replacement. The assembly piece 102 and handle 1 can be detached and assembled with one hand. The marker pen 4 works with the assembly piece 102; if a hollow area is detected during inspection, a light press on the marker pen 4 removes the mark. In dimly lit environments, flipping the assembly piece 102 so that the light 5 faces the work surface and pressing the switch 105 on the battery compartment 103 illuminates the light, eliminating the need to search for and switch tools in the toolbox.

[0024] The battery compartment 103, compartment cover 104, battery block 6, switch 105, and lighting lamp 5 constitute an independent power supply system. The battery block 6 is embedded between the compartment cover 104 and the battery compartment 103, and the switch 105 connects the battery block 6 and the lighting lamp 5 in series. The inner sealing structure of the compartment cover 104 fits snugly against the edge of the battery compartment 103 to prevent the battery block 6 from loosening or shifting. Inspectors control the lighting lamp 5 by pressing the switch 105 according to ambient light conditions. The battery block 6 provides a continuous and stable power supply, ensuring smooth inspection work in complex lighting environments without the need for additional lighting equipment or external power sources.

[0025] like Figures 1 to 3 As shown, the telescopic rod 2 has a threaded connector 201 at one end near the handle 1, allowing for a detachable connection between the telescopic rod 2 and the handle 1. A sponge-material gripper 301 is also fitted onto the handle 1. The threaded connector 201 at the end of the telescopic rod 2 matches the internal thread structure in the mounting groove of the handle 1, allowing for a detachable connection by rotation. This threaded connection allows the telescopic rod 2 to be quickly installed onto the handle 1, meeting the length requirements for inspecting high walls. When not in use, it can be separated by rotating in the opposite direction, facilitating storage and carrying. Simultaneously, the threaded engagement provides a secure connection, preventing the telescopic rod 2 from easily loosening or falling off during inspection, ensuring stable operation. The sponge-material gripper 301 on the handle 1 increases the contact area between the hand and the handle 1. When the operator holds the device for extended periods, the gripper 301 distributes hand pressure, preventing hand soreness caused by prolonged stress. Furthermore, the sponge material has a certain friction, which can prevent the handle 1 from slipping in the hand when the hand applies force to strike or adjusts the angle during the testing process, allowing the tester to control the striking hammer 3 more accurately for testing operations.

[0026] like Figure 2As shown, each of the two sets of striking hammers 3 has a mounting part 401 on one of its opposite sides. The two sets of striking hammers 3 are interchangeably secured to both sides of the mounting component 101 via the mounting parts 401. The mounting parts 401 on the opposite sides of the two sets of striking hammers 3 correspond to the two sides of the mounting component 101. During testing, depending on the wall material and thickness requirements, without tools, one side of the striking hammer 3 can be removed from both sides of the mounting component 101 by pressing the mounting part 401 with one hand, and simultaneously the appropriate model of striking hammer 3 on the other side can be inserted, enabling quick switching between different striking heads to meet the needs of diverse testing scenarios. The two sets of striking hammers 3 are symmetrically installed on both sides of the mounting component 101, ensuring even force distribution across the entire device. When the testing personnel hold the handle 1, the two sets of striking hammers 3 form a balanced weight, preventing the device from tilting due to excessive weight on one side, ensuring smooth striking action, reducing hand fatigue, and improving the accuracy and stability of the testing operation.

[0027] like Figures 3 to 4 As shown, a magnetic block 501 is provided at the top of the assembly 102, and the assembly 102 contacts the bottom of the handle 1 through the magnetic block 501. A slot 601 is provided at the end of the assembly 102 near the storage cavity, and the bottom of the marker 4 is detachably locked in the slot 601. The magnetic block 501 at the top of the assembly 102 and the bottom of the handle 1 form a magnetic attraction, automatically aligning and fixing upon contact, without the need for screwing or pressing, and the connection between the assembly 102 and the handle 1 can be completed with one hand. When disassembling, a light external force can be applied to separate them, making it easy to quickly remove the assembly 102 to use the lighting lamp 5 according to the testing needs, or to reduce the size of the device when storing it, making it more convenient to carry. During the testing process, the magnetic block 501 provides a stable attraction force to ensure that the assembly 102 will not fall off accidentally, ensuring the stable and usable lighting function; the slot 601 at the end of the assembly 102 near the storage cavity is adapted to the buckle structure at the bottom of the marker 4. Before testing, the marker 4 is stored in the storage cavity of the handle 1, with one end locked into the slot 601 to prevent shaking or falling. If a hollow area is detected, the assembly 102 and its remaining components can be quickly disassembled using the magnetic block 501. The marker 4 can then be quickly unlocked from the slot 601 and removed to mark the hollow area. After marking, the bottom of the marker 4 is aligned with the slot 601 and inserted; the latch automatically engages, allowing the marker 4 to quickly return to its original position. This avoids wasting time searching for marking tools during testing and improves testing efficiency.

[0028] like Figures 3 to 4As shown, a sealing element 701 is also provided at the end of the cover 104 near the battery compartment 103, and the sealing element 701 contacts the battery compartment 103. The sealing element 701 on the cover 104 is in close contact with the battery compartment 103 to prevent dust, wall debris and other fine particles from entering the compartment during the testing process, forming a closed space. In a humid testing environment or when splashed with water, the sealing element 701 prevents moisture from entering the battery compartment 103, avoiding short circuits and corrosion of the battery block 6 due to moisture, extending the battery life, and ensuring a stable power supply for the lighting lamp 5. At the same time, when the cover 104 is closed, the sealing element 701 is deformed under pressure to fill the gaps, increasing the friction between the cover 104 and the battery compartment 103, making the cover 104 less likely to loosen and fall off, firmly protecting the battery block 6, and preventing abnormal noise caused by shaking from affecting the testing judgment.

[0029] The above description is merely an embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
