Description

Technical Field

[0001] The utility model relates to the technical field of hollow drum detection, in particular to a portable hollow drum detector. Background Art

[0002] Hollowing is caused by the presence of air in the original masonry and powder ash layer. During detection, use a hollowing hammer or a hard object to tap the plaster layer and leveling layer, and a thudding sound is heard, which is hollowing. Hollowing detection is a key link in project management. The hammering method is a traditional and direct detection method. By using a small hammer to tap the wall, it is judged whether there is a hollow behind the wall based on the different sounds. This method is simple, easy, low-cost, and often used for local detailed inspections.

[0003] For example, the application number is CN202321666072.0. The utility model relates to the technical field of hollow drum detectors and discloses a hollow drum detector comprising a hollow drum hammer head, a marking mechanism connected to the back of the hollow drum hammer head, a rotating mechanism connected to a rotating mechanism, and a telescopic mechanism connected to the rotating mechanism; the rotating mechanism comprises a shell, and a square hole is provided on the side of the shell. The hollow drum detector can rotate the hollow drum hammer head to a horizontal or plumb state through the rotating mechanism, so that the hollow drum detection device can perform hollow drum detection on both plumb surfaces such as walls and horizontal surfaces such as ceilings, making the hollow drum detector more convenient to use. After opening the circular cover connected to the side of the rotating shaft and the annular groove and circular hole provided on the rotating shaft, the push rod and telescopic shaft engaged on the cylinder are removed, and the hollow drum detection head can be removed, making it convenient for the hollow drum detector to replace the hollow drum detection head, so that the hollow drum detector can adapt to various different planes for detection.

The hollow detection hammer is relatively long and is prone to collision with surrounding equipment or walls during carrying. At the same time, some staff will hold the handle of the hollow detection hammer when carrying it, causing the hammer head to drag on the ground, thereby increasing the degree of wear on the hammer head.

The inner wall of the thread groove 102 is threadedly connected to the surface of the stud 101.

[0025] As a technical optimization solution of the present invention, by providing a disassembly component 10, after the user retracts the entire hammer, the user can also rotate the hammer body 2, so that the hammer body 2 drives the corresponding stud 101 to rotate, so that the stud 101 rotates and moves upward to disengage from the thread groove 102. Then the user can disassemble the hammer body 2, further reducing the overall length.

[0026] refer to Figure 1The splicing assembly 11 includes a splicing seat 111, the back of the splicing seat 111 is fixedly connected to the top of the front of the first telescopic cylinder 3, and a splicing block 112 is fixedly connected to the right side of the hammer body 2. The cross-section of the inner wall of the splicing seat 111 and the cross-section of the splicing block 112 are both T-shaped.

[0027] As a technical optimization solution of the present invention, by setting up the splicing assembly 11, after the user removes the pituitary body, the user can also splice the splicing block 112 on the hammer body 2 with the corresponding splicing seat 111, so as to facilitate the appropriate placement of the removed hammer head, further improving the convenience of carrying.

[0029] As a technical optimization solution of the present invention, by setting a limit component 12, during the movement of the plug-in 7, the sliding connection between the limit groove 122 and the limit block 121 is utilized to limit the plug-in 7 up and down, front and back, to prevent the plug-in 7 from being offset up and down, front and back, during the movement, causing the plug-in 7 to be unable to be inserted into the interior of the slot 8 or unable to be accurately moved into the movable groove 6, and at the same time, it can also prevent the plug-in 7 from being separated from the movable groove 6.

[0030] refer to Figure 3 The bottom of the inner wall of the splicing seat 111 is fixedly connected with a magnetic plate 13, and the top of the magnetic plate 13 is fixedly connected with a protective pad 14. The protective pad 14 is arranged in a mesh shape, and the material of the splicing block 112 is metal iron.

[0031] As a technical optimization solution of the present invention, by setting up a magnetic plate 13, after the user removes the hammer body 2 and inserts the splicing block 112 into the splicing seat 111, the magnetic force of the magnetic plate 13 can be used to adsorb the iron splicing block 112, thereby improving the stability of the splicing block 112 after splicing. By setting up a protective pad 14, the impact force generated by the magnetic plate 13 when adsorbing the splicing block 112 can be buffered by the protective pad 14 to prevent damage to the magnetic plate 13.

By setting the left side of the inner wall of the elastic splint 15 in a wavy shape, the friction between the elastic splint 15 and the user kit is increased, thereby improving stability.

[0034] refer to Figure 2 A placement groove 16 is provided at the bottom of the inner wall of the thread groove 102 , and a steel wire rope 17 is fixedly connected to the bottom of the inner wall of the placement groove 16 , and the other end of the steel wire rope 17 is fixedly connected to the bottom of the stud 101 .

[0035] As a technical optimization solution of the present invention, by providing a placement groove 16 and a wire rope 17, if the user forgets to splice the splicing block 112 and the splicing seat 111 after removing the hammer body 2, the wire rope 17 can be used to connect the hammer body 2 to the placement groove 16, which can avoid the hammer body 2 from being lost.

[0036] The working principle and use process of the utility model are as follows: when the user needs to carry and move the hammer body 2 and the grip rod 1, the user can push the plug-in 7 inward so that the plug-in moves to the inside of the movable groove 6, and then the user can retract the slide bar 5 into the inside of the second telescopic cylinder 4, and then retract the second telescopic cylinder 4 into the inside of the first telescopic cylinder 3, so that the retracted hammer body 2 and the grip rod 1 can be conveniently carried, and then the user can also rotate the hammer body 2 so that the hammer body 2 drives the corresponding stud 101 to rotate, so that the stud 101 rotates and moves upward to disengage from the threaded groove 102, and then the user can disassemble the hammer body 2, further reducing The overall length, at the same time, the user can also splice the splicing block 112 on the hammer body 2 with the corresponding splicing seat 111, so as to properly place the removed hammer head, further improving the convenience of carrying. During the activity of the plug-in 7, the sliding connection between the limit groove 122 and the limit block 121 is utilized to limit the plug-in 7 up and down, front and back, and prevent the plug-in 7 from deviating up and down, front and back, during the movement, causing the plug-in 7 to be unable to be inserted into the interior of the slot 8 or unable to be accurately moved into the movable slot 6. At the same time, it can also prevent the plug-in 7 from being separated from the movable slot 6, and has the ability of convenient carrying.

[0037] To sum up: this portable hollow drum detector, by setting a first telescopic cylinder 3 and a second telescopic cylinder 4, pushes the plug-in 7 inward to the inside of the movable groove 6, and then the user can retract the slide rod 5 to the inside of the second telescopic cylinder 4, and then retract the second telescopic cylinder 4 to the inside of the first telescopic cylinder 3, thereby reducing the overall length and solving the problem that the existing hollow drum detection hammer is not convenient to carry when used. The hollow drum detection hammer is relatively long and is prone to collision with surrounding equipment or walls during carrying. At the same time, some staff will hold the handle of the hollow drum detection hammer when carrying it, causing the hammer head to drag on the ground and slide, thereby increasing the degree of wear on the hammer head.
