Description

Technical Field

[0001] The utility model relates to the field of building decoration, and particularly relates to a hollow detection device for decoration acceptance inspection. Background Art

[0002] Hollow detection for decoration acceptance inspection is the hollow detection carried out during the decoration of buildings or facilities. When there are hollows in the wall or the bonding between tiles and the base layer is not firm during decoration, it will cause local or overall loosening, affecting the service life of the tiles or the aesthetics of the house. Therefore, it is necessary to detect it. This solution specifically relates to a hollow detection device for decoration acceptance inspection;

[0003] When the existing hollow detection device is in use, the sphere vibrates when rubbing against the wall for detection. Prolonged detection will make the staff's hands numb. The vibration amplitude of the sphere is small, which is not convenient for providing a buffering effect. Detecting by knocking the wall with the sphere is likely to cause damage to the sphere. When the hollow position is high, it is not convenient to quickly mark. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a hollow detection device for decoration acceptance inspection, which can effectively solve the technical problems in the background art.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A hollow detection device for decoration acceptance inspection includes a handle and a telescopic rod. The top end of the telescopic rod is fixedly installed with a positioning seat. One end of the positioning seat is installed with a detection component. The detection component includes a buffer cylinder. The buffer cylinder is fixedly installed at one end of the positioning seat. A first contraction groove is opened inside the buffer cylinder. A spiral groove is arranged in the middle of the inner wall of the first contraction groove. A sphere is movably installed through the outer end of the buffer cylinder. A spiral disc is installed inside the inner end of the sphere and located inside the first contraction groove. A first spring is installed inside the spiral disc. A tapered rod is installed through the inside of the sphere and the spiral disc.

[0007] As a further solution of the utility model, the inner end of the tapered rod is fixedly installed with the buffer cylinder, and the sphere and the spiral disc are sleeved outside the tapered rod and are slidably arranged.

[0008] As a further solution of the utility model, the sphere is slidably telescopic at the outer end of the buffer cylinder, and the outer diameter of the spiral disc matches the inner diameter of the inner wall of the first contraction groove.

[0009] As a further solution of the utility model, a threaded section is arranged outside the spiral disc, and the spiral disc is threadedly connected with the spiral groove.

[0010] As a further solution of the present utility model, a marking component is installed at the other end of the positioning seat. The marking component includes a storage cylinder. A second contraction groove is formed inside the storage cylinder. A positioning disk is movably installed inside the second contraction groove. Two sliding grooves are formed outside the storage cylinder. Fastening bolts are movably installed in both of the sliding grooves through the periphery of the positioning disk. A second spring is installed inside the second contraction groove on the inner side of the positioning disk. A hanging groove is formed at the inner end of the sliding groove.

[0011] As a further solution of the present utility model, the inside of the positioning disk and the storage cylinder is used to install a marker pen. The positioning disk is slidably arranged inside the second contraction groove. The fastening bolt penetrates through the inside of the positioning disk and is arranged in a threaded connection.

[0012] As a further solution of the present utility model, the fastening bolt is slidably arranged in the sliding groove and is hung in the hanging groove.

[0013] The beneficial effects of the present utility model are as follows:

[0014] By providing a detection component, the sphere rubs against the wall to detect whether the wall is hollow. Through the telescopic sliding of the first spring, the vibration generated by the friction between the sphere and the wall on the handle is reduced, which can provide a buffering effect on the sphere, increase the vibration amplitude of the sphere, and improve the detection accuracy. Through the threaded connection between the screw disk and the screw groove, the fixing cone rod of the sphere extends, and the wall or the hollow part can be knocked and detected, reducing the damage caused by the collision to the sphere;

[0015] By providing a marking component, the marker pen is fixed to the positioning disk and slides adaptively under the action of the second spring, which is convenient for quickly marking the hollow position at a higher place and preventing damage caused by excessive pressure when the marker pen contacts the wall. Through the sliding of the positioning disk, the fastening bolt is hung in the hanging groove, which is convenient for the storage of the marker pen and easy to carry. Description of the Drawings

Detailed implementation mode

[0021] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with the specific implementation modes.

[0022] As Figures 1-4 shown, a hollow drum detection device for decoration acceptance includes a grip 1 and a telescopic rod 2. The top end of the telescopic rod 2 is fixedly installed with a positioning seat 3. One end of the positioning seat 3 is installed with a detection component 4. The detection component 4 includes a buffer cylinder 6. The buffer cylinder 6 is fixedly installed at one end of the positioning seat 3. A first contraction groove 7 is opened inside the buffer cylinder 6. A thread groove 8 is arranged in the middle of the inner wall of the first contraction groove 7. A sphere 9 is movably installed through the outer end of the buffer cylinder 6. A thread disc 10 is installed inside the sphere 9 and located inside the first contraction groove 7. A first spring 11 is installed inside the thread disc 10. A taper rod 12 is installed through the inside of the sphere 9 and the thread disc 10.

[0023] In this embodiment, the inner end of the taper rod 12 is fixedly installed with the buffer cylinder 6. The sphere 9 and the thread disc 10 are sleeved outside the taper rod 12 and are slidably arranged. The sphere 9 slides on the wall surface for detecting the hollow drum. Through the sliding and telescoping of the sphere 9, buffering is provided.

[0024] In this embodiment, the sphere 9 is slidably telescoped at the outer end of the buffer cylinder 6. The outer diameter of the thread disc 10 matches the inner diameter of the inner wall of the first contraction groove 7. The thread disc 10 guides the sliding of the sphere 9 to provide buffering for the sphere 9 and reduce the vibration of the telescopic rod 2 and the grip 1.

[0025] In this embodiment, a thread section is arranged outside the thread disc 10. The thread disc 10 is threadedly connected with the thread groove 8. Press the sphere 9 and rotate it to make the thread disc 10 threadedly connected with the thread groove 8 for fixation. Then the end of the taper rod 12 extends out, and the hollow drum of the wall can be knocked.

[0026] In this embodiment, a marking component 5 is installed at the other end of the positioning seat 3. The marking component 5 includes a storage cylinder 13. A second contraction groove 14 is formed inside the storage cylinder 13. A positioning disk 15 is movably installed inside the second contraction groove 14. Two sliding grooves 16 are formed outside the storage cylinder 13. Fastening bolts 17 are movably installed in both of the two sliding grooves 16 through the periphery of the positioning disk 15. A second spring 18 is installed inside the second contraction groove 14 on the inner side of the positioning disk 15. A hanging groove 19 is formed at the inner end of the sliding groove 16. The end of a marking pen 20 is inserted into the storage cylinder 13 and the positioning disk 15, and the hollow drum position at a high place is marked by the marking pen 20.

[0027] In this embodiment, the interior of the positioning disk 15 and the storage cylinder 13 is used to install the marking pen 20. The positioning disk 15 is slidably arranged inside the second contraction groove 14. The fastening bolt 17 penetrates through the inside of the positioning disk 15 and is arranged in a threaded connection. The end of the marking pen 20 is pressed and fixed by the fastening bolt 17. The positioning disk 15 drives the marking pen 20 to slide adaptively, preventing the marking pen 20 from being damaged due to excessive contact pressure with the wall surface.

[0028] In this embodiment, the fastening bolt 17 is slidably arranged inside the sliding groove 16 and is arranged in a hanging connection inside the hanging groove 19. During the sliding process of the positioning disk 15, the fastening bolt 17 slides inside the sliding groove 16. The positioning disk 15 is rotated by the fastening bolt 17, and the fastening bolt 17 is hung and fixed inside the hanging groove 19, thereby enabling the marking pen 20 to contract inside the storage cylinder 13.

[0029] It should be noted that the present utility model is a hollow drum detection device for decoration acceptance. When in use, the height position of detection is adjusted through the telescopic movement of the telescopic rod 2. When detecting, the sphere 9 slides on the wall surface, and whether there is a hollow drum inside the wall is judged through the friction sound. During the sliding process of the sphere 9, vibrations are generated. Under the action of the first spring 11, the sphere 9 performs adaptive telescopic movement and provides buffering, reducing the vibration to the handle 1. When it is necessary to knock on the wall surface or the hollow drum for detection, the sphere 9 is pressed and rotated, so that the screw disk 10 is in threaded connection with the screw groove 8 for fixation. At the same time, the end of the taper rod 12 extends out, and the end of the taper rod 12 is used to knock on the wall surface or the hollow drum. When a hollow drum is detected at a high place, by rotating the handle 1, the tip of the marking pen 20 pre-fixed inside the positioning disk 15 and the storage cylinder 13 is brought into contact with the wall surface, and the hollow drum is marked by the marking pen 20. During the marking process, under the action of the second spring 18, the marking pen 20 adapts to contract, preventing the marking pen 20 from being damaged due to overpressure contact with the wall surface. When carrying, the positioning disk 15 is pushed to slide inwards by the two fastening bolts 17, so that the marking pen 20 contracts into the second contraction groove 14, and the positioning disk 15 is rotated to make the fastening bolts 17 hang and fixed inside the hanging groove 19.
