Description

Technical Field

[0001] The utility model belongs to the technical field of floor hollowing detection, and in particular relates to floor hollowing detection equipment. Background Art

[0002] A floor hollow hammer is a device for detecting hollows in floors. Hollowing refers to the phenomenon that the floor makes a hollow sound when knocked, which usually indicates that there is a gap between the floor and the base layer or poor bonding. This phenomenon may be caused by moisture, aging or damage to the bonding layer between the floor and the base layer. In summary, the problems existing in the prior art are: the floor hollow hammer includes a handle, a telescopic rod and a hammer head and other structures. The length of the telescopic rod can be adjusted during use, and then the ground is knocked by the hammer head for detection. The floor hollow detection hammer is usually one-piece and cannot be replaced. However, the hammer head is prone to dents or damage due to knocking after long-term use. Damage to the hammer head can easily affect the sound made when knocking, resulting in a decrease in the accuracy of hollow detection. However, the existing floor hollow hammer does not have a component for conveniently replacing the hammer head, so a floor hollow detection device is proposed to solve the above problems.

[0020] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

[0021] like Figures 1 to 4As shown, a floor hollowing detection device provided by an embodiment of the utility model includes a hollowing hammer handle 1 and a telescopic rod 2. The top of the hollowing hammer handle 1 is fixedly connected to the bottom of the telescopic rod 2. The inner cavity of the telescopic rod 2 is movably connected with a mounting shell 3. The top of the mounting shell 3 passes through the inner cavity of the telescopic rod 2 and extends to the outside of the inner cavity of the telescopic rod 2. The top of the mounting shell 3 is movably connected with a hammer head 4. The bottom of the inner cavity of the mounting shell 3 is fixedly connected with a square block 5. The top of the square block 5 is movably connected with a control rod 6 through a rotating shaft. The top of the control rod 6 passes through the mounting shell 3 and extends to the outside of the inner cavity of the mounting shell 3. The inner cavity of the mounting shell 3 is provided with a limiting device 7.

[0022] refer to Figure 4 The limiting device 7 includes two limiting blocks 701, and the opposite sides of the two limiting blocks 701 penetrate the mounting shell 3 and extend to the outside of the inner cavity of the mounting shell 3. The opposite sides of the two limiting blocks 701 are fixedly connected with the outer shell 702, and the inner cavity of the outer shell 702 is movably connected with the inner shell 703. The opposite sides of the two inner shells 703 are fixedly connected to the surface of the square block 5, and the opposite sides of the two outer shells 702 are fixedly connected with springs 704, and the opposite sides of the two springs 704 are fixedly connected to the surface of the square block 5.

[0023] The above solution is adopted: by providing the limiting device 7 , when the hammer head 4 moves to the top of the telescopic rod 2 , the limiting device 7 has a limiting effect on the position of the hammer head 4 .

[0024] refer to Figure 4 The inner cavity of the mounting shell 3 is provided with two extrusion tooth blocks 8, and the top of the limit block 701 is fixedly connected with an extrusion rod 9 used in conjunction with the extrusion tooth block 8, and the surface of the extrusion tooth block 8 is in contact with the surface of the extrusion rod 9.

[0025] The above solution is adopted: by providing the extrusion tooth block 8 and the extrusion rod 9, when the extrusion tooth block 8 moves, an extrusion force will be generated on the extrusion rod 9, and the extrusion rod 9 subjected to the extrusion force can drive the limit block 701 to move.

[0026] refer to Figure 4 A moving hole 10 is opened on the surface of the extrusion tooth block 8, and two moving blocks 11 used in conjunction with the moving hole 10 are fixedly connected to the top of the inner cavity of the mounting shell 3, and the surface of the moving block 11 is movably connected to the inner cavity of the moving hole 10.

[0027] The above solution is adopted: by setting the moving hole 10 and the moving block 11, when the extrusion tooth block 8 moves, the moving hole 10 can be driven to move along the surface of the moving block 11. The coordinated use of the moving hole 10 and the moving block 11 has a limiting effect on the moving position of the extrusion tooth block 8.

[0028] refer to Figure 4The surface of the control rod 6 is fixedly connected with a rotating toothed disc 12 used in conjunction with the extrusion tooth block 8, and the surface of the rotating toothed disc 12 is meshedly connected with the surface of the extrusion tooth block 8.

[0029] The above solution is adopted: by setting a rotating toothed disc 12, when the control rod 6 rotates, it will drive the rotating toothed disc 12 to rotate along the surface of the extruding tooth block 8, and the rotational force of the rotating toothed disc 12 on the extruding tooth block 8 can drive the two extruding tooth blocks 8 to move.

[0030] refer to Figure 3 The left and right sides of the inner cavity of the telescopic rod 2 are both provided with limiting grooves 13 used in conjunction with the limiting block 701 , and the surface of the limiting block 701 is in contact with the inner cavity of the limiting groove 13 .

[0031] The above scheme is adopted: by setting the limit groove 13, when the mounting shell 3 moves into the inner cavity of the telescopic rod 2, the hammer head 4 is released, and the restoring force generated by the spring 704 restoring its shape will drive the limit block 701 to be stuck into the inner cavity of the limit groove 13. The coordinated use of the limit block 701 and the limit groove 13 has a limiting effect on the position of the mounting shell 3.

[0032] refer to Figure 3 A clamping ring 14 is fixedly connected to the surface of the mounting shell 3 , and the bottom of the clamping ring 14 contacts the top of the telescopic rod 2 .

[0033] By adopting the above solution, by providing the clamping ring 14 , when the bottom of the clamping ring 14 contacts the top of the telescopic rod 2 , the limiting block 701 can be accurately moved to a position where it can be clamped into the inner cavity of the limiting groove 13 .

[0034] The working principle of this utility model:

[0035] During use, when it is necessary to conveniently replace the hammer head 4 of the floor hollow drum detection hammer, the user first removes the damaged hammer head 4 and then rotates the hammer head 4. When the hammer head 4 rotates, it will drive the control rod 6 to rotate on the top of the square block 5 through the rotating shaft. When the control rod 6 rotates, it will drive the rotating toothed disc 12 to rotate along the surface of the extruding tooth block 8. The extruding force generated by the rotating toothed disc 12 on the extruding tooth block 8 can drive the two extruding tooth blocks 8 to move toward one side close to each other. When the extruding tooth block 8 moves, it will drive the moving hole 10 to move along the surface of the moving block 11. When the extruding tooth block 8 moves, the extruding force generated on the extruding rod 9 will drive the two extruding rods 9 to move toward one side close to each other. When the limit block 701 moves, it will drive the two limit blocks 701 to move closer to each other. When the limit block 701 moves, it will drive the outer shell 702 to move along the surface of the inner shell 703. The force generated when the outer shell 702 moves causes the spring 704 to produce elastic deformation. When the limit block 701 is completely moved to the inner cavity of the mounting shell 3, the mounting shell 3 is placed in the inner cavity of the telescopic rod 2. When the bottom of the retaining ring 14 contacts the top of the telescopic rod 2, the hammer head 4 is released. The restoring force generated by the spring 704 restoring its shape will drive the limit block 701 to be stuck into the inner cavity of the limit groove 13. The coordinated use of the limit block 701 and the limit groove 13 has a limiting effect on the position of the hammer head 4. At this time, the hammer head 4 of the floor hollowing detection hammer is easily replaced.

[0036] To sum up: the floor hollowing detection equipment, by setting the limiting device 7, the limiting block 701, the outer shell 702, the inner shell 703 and the spring 704 for coordinated use, solves the problem that the existing floor hollowing hammer includes structures such as a handle, a telescopic rod and a hammer head. When in use, the length of the telescopic rod can be adjusted, and then the ground is knocked by the hammer head for detection. The floor hollowing detection hammer is usually one-piece and cannot be replaced. However, the hammer head is easily dented or damaged due to knocking after long-term use. The damage to the hammer head is easy to affect the sound emitted during knocking, resulting in a decrease in the accuracy of hollowing detection. However, the existing floor hollowing hammer does not have a component for conveniently replacing the hammer head.
