Description

Technical Field

[0001] This utility model relates to the field of wall detection technology, and in particular to a combined wall detection device. Background Technology

[0002] When inspecting walls, a hollow hammer is used to tap the wall to check for hollowness, and a wedge gauge is used to check for gaps in the wall. To facilitate the inspection, the hollow hammer and the wedge gauge are combined, as shown in patent authorization announcement number CN207231366U, entitled "A Combination Tool for Engineering Inspection". When using the feeler gauge, the telescopic inner rod is pulled up to disengage the locking rod from the limiting block, allowing the feeler gauge to rotate around the axis and measure the width of the gap. However, when using a hammer for tapping, the telescopic inner rod may move, causing the locking rod to release the feeler gauge and resulting in rotation of the feeler gauge during tapping, which affects the tapping inspection. Utility Model Content

[0003] The purpose of this invention is to solve the problem in the existing technology where the feeler gauge rotates during the tapping test, which affects the tapping test. Therefore, a combined wall testing device is proposed.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design a combined wall inspection device, including a gripping column, on which a multi-stage telescopic rod is fixedly connected, and a hammer head is fixedly connected to the multi-stage telescopic rod. The gripping column has an installation groove, and a rotating shaft is rotatably connected to the installation groove via a bearing. A wedge-shaped feeler gauge is fixedly connected to the rotating shaft, and a limit strip is fixedly connected to the wedge-shaped feeler gauge. A movable sleeve is fitted onto the limit strip, and a connecting block is fixedly connected to the movable sleeve. The gripping column has a guide groove, which communicates with the installation groove. A spring is fixedly connected between the guide groove and the connecting block.

[0006] Preferably, a movable block is fixedly connected to the connecting block, and the movable block is located within the guide groove.

[0007] Preferably, the movable block is provided with anti-slip texture.

[0008] Preferably, the connecting block has a limiting hole, and a connecting post is provided in the limiting hole, and the connecting post is fixedly connected to the inner wall of the guide groove.

[0009] Preferably, the spring is sleeved on the connecting post.

[0010] Preferably, an indicator needle is fixedly connected to the rotating shaft, and a mark is provided on the grip post, so that the indicator needle rotates to align with the mark.

[0011] Preferably, the gripping column is provided with a rubber layer.

[0012] The present invention proposes a combined wall detection device, which has the following advantages: by limiting the wedge gauge with the limiting strip and the moving sleeve, and at the same time limiting the position of the moving sleeve with the spring, the wedge gauge is prevented from rotating, thus avoiding the situation where the wedge gauge rotates out when the wall is struck, and avoiding interference with the wall striking.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-3 and Figure 5A combined wall inspection device includes a gripping column 3, on which a multi-stage telescopic rod 2 is fixedly connected, and a hammer head 1 is fixedly connected to the multi-stage telescopic rod 2. The gripping column 3 has an installation groove 5, and a rotating shaft 12 is rotatably connected to the installation groove 5 via a bearing. A wedge gauge 4 is fixedly connected to the rotating shaft 12. When it is necessary to inspect the gaps in the wall, the wedge gauge 4 is rotated out of the installation groove 5 to perform gap inspection.

[0021] A limiting strip 9 is fixedly connected to the wedge gauge 4. A movable sleeve 11 is fitted on the limiting strip 9. A connecting block 10 is fixedly connected to the movable sleeve 11. A guide groove 15 is opened on the grip post 3. The guide groove 15 is connected to the mounting groove 5. A spring 7 is fixedly connected between the guide groove 15 and the connecting block 10. By limiting the wedge gauge 4 with the limiting strip 9 and the movable sleeve 11, the wedge gauge 4 is limited. At the same time, the spring 7 limits the position of the movable sleeve 11, preventing the wedge gauge 4 from rotating. This avoids the wedge gauge 4 from rotating out when hitting the wall, thus avoiding interference with the wall.

[0022] A movable block 6 is fixedly connected to the connecting block 10. The movable block 6 is provided with anti-slip texture. The movable block 6 is located in the guide groove 15. When it is necessary to remove the movable sleeve 11 from the limiting strip 9, the wedge gauge 4 is turned out for use. By pressing the movable block 6, the connecting block 10 is moved, which drives the movable sleeve 11 to move, so that the spring 7 is compressed, thereby causing the limiting strip 9 to disengage from the movable sleeve 11. The spring 7 plays a limiting role on the movable sleeve 11.

[0023] A limiting hole is provided on the connecting block 10, and a connecting post 8 is provided in the limiting hole. The connecting post 8 is fixedly connected to the inner wall of the guide groove 15. The spring 7 is sleeved on the connecting post 8. By using the connecting post 8, the connecting block 10 is supported and limited, so that the connecting block 10 can only move along the connecting post 8.

[0024] Example 2: In Example 1, when the wedge gauge 4 is rotated into the mounting groove 5 and the wedge gauge 4 is retracted, it is difficult to align the limiting strip 9 with the movable sleeve 11. The movable sleeve 11 is then fitted onto the limiting strip 9, as shown in the following example. Figure 4 As another preferred embodiment of this utility model, based on embodiment 1, an indicator needle 13 is fixedly connected to the rotating shaft 12, and a marking point 14 is opened on the grip post 3. The indicator needle 13 rotates to align with the marking point 14. A rubber layer is provided on the grip post 3. By adopting the design of the indicator needle 13, when the indicator needle 13 is aligned with the marking point 14, the limiting strip 9 will be aligned with the movable sleeve 11 so that the movable sleeve 11 can be re-fitted onto the limiting strip 9.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
