Detailed Implementation

[0027] In order to make the purpose, technical scheme and advantages of the utility model clearer, the utility model will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model and not to limit the utility model. Based on the examples in the utility model, all other examples obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0028] Example one:

[0029] Reference Figure 1 A construction engineering quality safety risk management device, comprising a handheld end 10, a long arm 11 and a knocking end 12 for knocking the wall surface, the knocking end 12 is divided into a connecting column 121 and an inner ball 20, the connecting column 121 is detachably connected with the long arm 11, the inner ball 20 is used for knocking the wall surface, and a slot 202 is formed in the center of one side of the inner ball 20;

[0030] In the above scheme, the connecting column 121 is detachably connected with the long arm 11, the detachable connection mode is connected with each other in a threaded connection or nested plug-in mode, so that the replacement of the knocking end 12 can be conveniently realized; when the utility model is used, the handheld end 10 needs to be held for use, the long arm 11 is provided in a conventional cylindrical shape, mainly to prolong the knocking distance of the knocking end 12 of the utility model, so as to be applicable to the detection of the hollow drum wall surface position at a high place, and the overall practicability is realized; the inner ball 20 is knocked or contacted on the wall surface, the feedback of sound conduction is heard, and thus the position of the hollow drum is distinguished.

[0031] Further reference Figure 7 The long arm 11 is provided in a telescopic mode. The long arm 11 provided in a telescopic mode can conveniently adjust the extension distance of the long arm 11.

[0032] Preferred scheme reference Figure 2 And Figure 3 The inner ball 20 is provided with an outer ball 201 outside;

[0033] The expansion angle of the outer ball 201 is greater than 180 degrees.

[0034] In the preferred implementation, the inner ball 20 and the outer ball 201 are integrally formed to constitute a solid, the outer ball 201 is a knocking surface, and the design of the outer ball 201 compensates for the opening distance of the slot 202, improves the solid thickness of the knocking part of the inner ball 20 and the outer ball 201, and the solid ball setting can produce clearer sound feedback when the hollow drum rod knocks the wall, which helps the operator to more accurately judge the position and size of the hollow drum.

[0035] Example two: (in combination with example one)

[0036] Reference Figures 1-5The graffiti component is tightly inserted into the slot 202.

[0037] The graffiti component includes a pen tip 30, which is tightly inserted into a slot 202. One end of the pen tip 30 has a graffiti head 301. Because the slot 202 is located on the side of the inner ball 20, after tapping to determine the location of the hollow area, the pen tip 30 can be directly used for marking by holding the hand end 10 and rotating it so that the pen tip 30 faces the wall. It is simple and convenient to use, and the graffiti head 301 is used for marking. The side graffiti method reduces the difficulty of marking and is more convenient than when the pen tip 30 is located at the front of the ball head.

[0038] It should be noted that the pen tip 30 is primarily made of polymer materials such as plastic and fiber. These materials enable the graffiti tip 301 to leave clear and durable marks or symbols on various materials such as paper, wood, metal, plastic, and enamel. The "tight fit" here relies on static friction to achieve installation, which is an interference fit, thus improving the stability of the pen tip 30 inside the slot 202.

[0039] The pen tip 30 has symmetrical cuts 302 on both sides of its outer wall. When it is necessary to remove the pen tip 30 from the slot 202, the force is applied to both ends of the cut 302 by using tweezers or other clamping tools. This makes it easier to pull out the pen tip 30 without slipping, thus improving the convenience of replacing and installing the pen tip 30.

[0040] The groove 202 and the pen tip 30 are elliptical in structure.

[0041] Example 3: (in conjunction with Example 2)

[0042] refer to Figure 2 Figures and Figure 3 The connecting column 121 has a capacity groove 122. The inner ball 20 of the capacity groove 122 has a liquid guiding channel 203 that communicates with the groove opening 202. The end of the liquid guiding channel 203 has an internal thread 123. The capacity groove 122 is equipped with a storage tank 50. One end of the storage tank 50 is equipped with a connector 501 that meshes with the internal thread 123.

[0043] In the above solution, the storage tank 50 stores ink pigment. When installing the storage tank 50, the striking end 12 of the present invention should face upwards. The storage tank 50 is placed into the capacity groove 122, and the storage tank 50 is rotated. With the mutual engagement of the connector 501 and the internal thread 123, the storage tank 50 is stabilized in the capacity groove 122. Finally, the storage tank 50 is shaken to allow the ink pigment inside to enter the liquid guiding channel 203, and the pen tip 30 absorbs the ink pigment inside the liquid guiding channel 203, thereby maintaining the long-term effective use of the pen tip 30. The overall structure is easy to assemble and disassemble.

[0044] The storage tank 50 is made of transparent material; this allows users to easily observe the liquid volume inside the storage tank 50, facilitating subsequent disassembly and replacement of the storage tank 50, or refilling the storage tank 50 with solution. It should be noted that when the storage tank 50 needs to be removed and there is still solution remaining inside, the striking end 12 of the present invention should be vertically downwards, and the storage tank 50 can be removed by rotating it, thereby preventing the solution inside the storage tank 50 from spilling out.

[0045] Further reference Figure 2 and Figure 3 The upper sides of the capacity slot 122 are symmetrically recessed openings 124; the recessed openings 124 are designed so that fingers can be inserted into the recessed openings 124, thereby facilitating the rotation of the storage tank 50 under force.

[0046] Example 4:

[0047] refer to Figure 6 A spring 401 is connected to the bottom of the capacity slot 122, and a washer 40 is connected to the top of the spring 401.

[0048] This embodiment is a modification and adjustment based on embodiment three. Instead of using the connection method of connector 501 and internal thread 123, a socket connection method is adopted. When connector 501 of storage tank 50 and liquid guiding channel 203 are socketed together, gasket 40 will be supported at the bottom of storage tank 50, and the installation is completed by the thrust applied by spring 401.

[0049] Meanwhile, the storage tank 50 can also be connected using the connector 501 and the internal thread 123. Similarly, the gasket 40 will be supported at the bottom of the storage tank 50, and the thrust applied by the spring 401 can further improve the installation stability of the storage tank 50.

[0050] The specific implementation process of this utility model is as follows:

[0051] Hold the handheld end 10 and tap or touch the wall with the outer ball 201 to listen to the sound feedback, thereby identifying the location of the hollow spot; after determining the location of the hollow spot, hold the handheld end 10 and rotate the angle so that the pen tip 30 can be directly used for marking. It is simple and convenient to use, and the graffiti head 301 is used for marking.

[0052] When installing the storage tank 50, the striking end 12 of the present invention should face upwards. Place the storage tank 50 into the capacity groove 122, rotate the storage tank 50, and stabilize the storage tank 50 in the capacity groove 122 by the mutual engagement of the connector 501 and the internal thread 123. Finally, shake the storage tank 50 to allow the ink pigment inside to enter the liquid guiding channel 203, and the pen tip 30 absorbs the ink pigment inside the liquid guiding channel 203, thereby maintaining the long-term effective use of the pen tip 30.
