[0002] With the development of society, more and more buildings are being built. After the construction of the houses is completed, they need to be inspected. When inspecting the houses, many places need to be inspected. Among them, the inspection of the hardness of the house wall is particularly important. The quality of the wall is the key to whether the subsequent decoration can proceed normally.

[0003] Currently, when testing the hardness of a house wall, a person needs to knock on it with a small hammer, and then judge the hardness of the wall by observing whether there are any damage or dents at the place where the wall is knocked. However, this method is not accurate enough, and the knocker cannot guarantee that the force applied is the same every time, which results in different forces being applied to the wall each time.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. When the present invention is used, level the entire detection device and make the force-applying rod perpendicular to the wall surface. Then quickly push the housing to drive the energy storage tube, the guiding tube and the tube head to move towards the wall surface. When the energy storage tube, the guiding tube and the tube head move, they will compress the energy storage spring and the reset spring. When the reset spring is compressed to the limit, the energy storage tube, the guiding tube and the tube head will no longer move. At this time, a displacement will occur between the transition rod and the hammer head. When the transition rod has a displacement, it will enter the circular groove.

[0017] 2. When the present invention is used, when it is necessary to change the impact force of the force-applying rod on the wall surface, repeat the above operation and then rotate the two strong magnets to make them approach the limiting tube of the housing. Then rotate the rotating ring to align the adjusted strong magnet with the limiting tube corresponding to the two elastic ropes in the same group. When the strong magnet is aligned with the limiting tube, it will adsorb the limiting pin and make it approach the inner wall of the housing through the limiting hole. Then push the rotating cap to make the power gear engage with the telescopic column. Then continue to push the rotating cap until it cannot be pushed any further. At this time, the power gear is in a state of meshing with the driving gear. Then rotate the rotating cap to wind up the traction rope through the wire winding wheel. When the traction rope is wound up, it will drive the energy storage plate to move towards the direction close to the rotating cap. When the energy storage plate moves, it will pull the traction rope. When the energy storage plate cannot move, stop rotating the rotating cap. Then release the rotating cap. When the rotating cap is released, the telescopic column will push the power gear to separate from the driving gear. After the power gear is separated from the driving gear, the energy storage plate will strike the energy storage tube under the action of the elastic rope, so that the force-applying rod has a stronger impact force to impact the wall surface, so as to detect the wall surface; the present invention can further adjust the force application magnitude and keep the force application magnitude stable.

[0018] 3. Through the arrangement of multiple groups of elastic ropes and rotating rings, different groups of elastic ropes or combinations of multiple groups of elastic ropes can be selected in the present invention, so that the detection device can exert different forces, and thus the present invention can be used in different detection environments.

The number of the strong magnets 120 is the same as that of the elastic ropes 112.

[0038] The working principle of the present invention is:

[0039] When in use, level the entire detection device so that the force application rod 209 is perpendicular to the wall surface. Then quickly push the outer shell 1 to drive the energy storage tube 200, the guide tube 201, and the tube head 202 to move towards the wall surface. When the energy storage tube 200, the guide tube 201, and the tube head 202 move, they will compress the energy storage spring 205 and the return spring 208. When the return spring 208 is compressed to the limit, the energy storage tube 200, the guide tube 201, and the tube head 202 will no longer move. At this time, a displacement will occur between the transition rod 207 and the hammer head 203 (since the lower end of the hammer head 203 is frustum-shaped, and the transition rod 207 is initially inclined in the tube head 202, and the upper end of the force application rod 209 is conical. Therefore, when the energy storage tube 200, the guide tube 201, and the tube head 202 are quickly pushed until the return spring 208 is compressed to the limit, the position of the transition rod 207 in the tube head 202 will change). The displacement of the transition rod 207 will cause it to enter the circular groove 204. The moment the transition rod 207 enters the circular groove 204, the energy storage spring 205 will be released, and the hammer head 203 will strike the force application rod 209, and then impact the wall surface through the force application rod 209, thereby detecting the wall surface;

[0040] When it is necessary to change the impact force of the force application rod 209 on the wall surface, repeat the above operation and then rotate two strong magnets 120 (the two rotated strong magnets 120 should correspond to the two elastic ropes 112 in the same group. According to requirements, two, four, or six can be rotated at a time) to make them approach the direction of the limit tube 110 of the outer shell 1. Then rotate the rotating ring 118 to align the adjusted strong magnets 120 with the limit tubes 110 corresponding to the two elastic ropes 112 in the same group. When the strong magnets 120 are aligned with the limit tubes 110, they will adsorb the limit pins 115, causing them to approach the inner wall of the outer shell 1 through the limit holes 117. Then push the rotating cap 106 to make the power gear 107 engage with the telescopic column 131. Then continue to push the rotating cap 106 until it cannot be pushed anymore. At this time, the power gear 107 is in a meshing state with the driving gear 105. Then rotate the rotating cap 106 to wind up the traction rope 108 through the wire winding wheel 104. When the traction rope 108 is wound up, it will drive the energy storage plate 100 to move towards the direction of the rotating cap 106. When the energy storage plate 100 moves, it will pull the traction rope 108. When the energy storage plate 100 cannot move, stop rotating the rotating cap 106. Then release the rotating cap 106. When the rotating cap 106 is released, the telescopic column 131 will push the power gear 107 to separate from the driving gear 105. After the power gear 107 separates from the driving gear 105, the energy storage plate 100 will strike the energy storage tube 200 under the action of the elastic rope 112, and then the force application rod 209 will have a stronger impact force to impact the wall surface, thereby inspecting the wall surface.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
