Description

Technical Field

[0001] This utility model relates to the field of gypsum-based self-leveling construction technology; specifically, this utility model relates to a defoaming roller for gypsum-based self-leveling mortar floor construction. Background Technology

[0002] In gypsum-based self-leveling flooring construction, defoaming rollers (also known as nail rollers or defoaming nail rollers) are key tools for eliminating air bubbles. They directly puncture suspended air bubbles by inserting their nails into the mortar surface. The conical nail tips of defoaming rollers create escape channels for gas within the mortar, resulting in better defoaming and improved construction quality. However, during use, after the nail tips wear down, the entire defoaming roller is typically replaced. This leads to wasted unworn nails, increasing construction costs. This is mainly because current defoaming rollers have their nails integrally molded with the roller body. Therefore, this application provides a defoaming roller for gypsum-based self-leveling mortar flooring construction. Utility Model Content

Detailed Implementation

[0027] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] Please refer to Figures 1 to 3 A defoaming roller for gypsum-based self-leveling mortar floor construction includes a cylinder body 1, conical nail teeth 2, and nail tooth plates 3. The conical nail teeth 2 are equidistantly arranged on the nail tooth plates 3, and the conical nail teeth 2 are detachably connected to the nail tooth plates 3. The nail tooth plates 3 are arranged in a ring on the surface of the cylinder body 1, and the ends of the nail tooth plates 3 are engaged with the ends of the cylinder body 1. The nail tooth plates 3 are connected end to end in the circumferential direction.

[0029] In this embodiment, the detachable connection between the toothed plate 3 and the cylinder 1 allows the conical teeth 2 to be removed from the cylinder 1 in rows. Furthermore, the detachable connection between the conical teeth 2 and the toothed plate 3 allows each conical tooth 2 to be removed individually from the toothed plate 3. This design enables the individual replacement of the conical teeth 2 on the defoaming roller, avoiding the need to replace the entire defoaming roller after localized wear of the conical teeth 2, thus reducing operating costs. Additionally, when cleaning the defoaming roller, the conical teeth 2 can be disassembled for more effective cleaning of the dirt that has hardened on them.

[0030] Please refer to Figures 3 to 5 The cylinder 1 has annular connecting portions 4 protruding from both ends, and the toothed plate 3 has a sleeve groove 5 at its end, which is fitted onto the connecting portion 4. In this embodiment, the sleeve groove 5 is located at both ends of the inner side surface of the toothed plate 3. By fitting the connecting portion 4 onto the sleeve groove 5, the toothed plate 3 can be axially limited in the cylinder 1, improving the stability of the toothed plate 3, and at the same time, making it easier to install and align the toothed plate 3.

[0031] Please refer to Figure 6 and Figure 7 , Figure 9 and Figure 10 The outer surface of the connecting part 4 is provided with an annular first snap-fit ​​protrusion 6, and the inner wall of the sleeve groove 5 is provided with a first snap-fit ​​groove 7 that matches the first snap-fit ​​protrusion 6. In this embodiment, both the toothed plate 3 and the connecting part 4 are made of plastic. During the process of the sleeve groove 5 fitting onto the connecting part 4, the end of the toothed plate 3 passes over the first snap-fit ​​protrusion 6 after being deformed by its own compression, so that the first snap-fit ​​groove 7 fits onto the first snap-fit ​​protrusion 6. This arrangement can stabilize the toothed plate 3 on the cylinder 1 and improve the stability of the toothed plate 3.

[0032] Please refer to Figure 5 , Figures 8 to 10 A circular end plate 8 is threaded onto the end of the cylinder 1. A second engaging groove 10 is provided on the end face of the toothed plate 3. An annular second engaging protrusion 9 engages within the second engaging groove 10, and the end plate 8 presses the second engaging protrusion 9 firmly within the second engaging groove 10. In this embodiment, after the toothed plate 3 is installed on the cylinder 1, the second engaging protrusion 9 is placed into the second engaging groove 10, and then the end plate 8 is rotated to press the second engaging protrusion 9 firmly within the second engaging groove 10. At this time, the cooperation between the first engaging protrusion 6 and the second engaging protrusion 9 further improves the stability of the toothed plate 3.

[0033] Furthermore, a threaded post 11 protrudes outward from the center of the end face of the cylinder 1, and the end plate 8 is threadedly fitted onto the threaded post 11. A connecting rod 12 is fixedly connected to the outer end of the threaded post 11. The inner surface of the connecting rod 12 is smooth, and the outer part of the connecting rod 12 is a threaded rod. A connecting nut 13 is threadedly connected to the outer part of the connecting rod 12. The connecting rod 12 is used to pass through the connecting hole on the defoaming roller handle. Then, by rotating the connecting nut 13 from the outside of the defoaming roller inward, the handle is pressed against the end face of the threaded post 11. When the end plate 8 is rotated in the opposite direction to separate the end plate 8 from the second locking protrusion 9, and the second locking protrusion 9 can separate from the second locking groove 10, the end plate 8 is still located on the threaded post 11. Therefore, during the disassembly of the toothed plate 3, it is not necessary to disassemble the handle of the defoaming roller.

[0034] Please refer to Figure 5 and Figure 7 The conical nail tooth 2 includes a conical portion 2.1 and a cylindrical portion 2.2 located inside the conical portion 2.1. A mounting groove 14 is provided on the nail tooth plate 3. The conical portion 2.1 of the nail tooth passes through the mounting groove 14, and the cylindrical portion 2.2 of the conical nail tooth 2 is located within the mounting groove 14. After the conical portion 2.1 passes through the mounting groove 14, so that the cylindrical portion 2.2 is located within the mounting groove 14, the conical nail tooth 2 can be installed onto the nail tooth plate 3. When removing the conical nail tooth 2, it can be directly pulled out from the mounting groove 14.

[0035] Please refer to the figure. The inner surface of the toothed plate 3 has a groove 15, and a pad 16 is placed within the groove 15. The pad 16 supports the inner end of the conical tooth 2. The pad 16 limits the inner end of the conical tooth 2, preventing it from detaching from the toothed plate 3. After the toothed plate 3 is installed on the cylinder 1, the pad 16 supports the surface of the cylinder 1 and is fixed in conjunction with the toothed plate 3, ensuring sufficient stability for the conical tooth 2.

[0036] Please refer to Figure 5 , Figure 7 and Figure 10 Both ends of the outer side of the pad 16 are fixedly installed with elastic clips 17, and both ends of the inner side of the nail tooth plate 3 are provided with third snap-fit ​​grooves 18. The elastic clips 17 are inserted into the third snap-fit ​​grooves 18. The elastic clips 17 are hollow metal springs, and the outer ends of the elastic clips 17 are arched to form snap-fit ​​parts. The bottom of the third snap-fit ​​groove 18 is set to a shape that matches the snap-fit ​​parts.

[0037] During the insertion of the elastic clip 17 into the third clip slot 18, the clip portion will be squeezed and deformed. After the clip portion enters the third clip slot 18, it will return to its initial state. At this time, the clip portion and the third clip slot 18 form a clip, stabilizing the pad 16 on the nail tooth plate 3, and the conical nail tooth 2 can be initially installed on the nail tooth plate 3.

[0038] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
