Technical Field

[0001] This utility model belongs to the technical field of home decoration grouting, specifically relating to a grouting and smoothing device for home decoration. Background Technology

[0002] Grout sealant offers a wide range of colors to match different tile colors and home decor styles, beautifying the gaps and making the entire living space more harmonious and aesthetically pleasing. It also boasts excellent waterproof, stain-resistant, and mildew-resistant properties, effectively preventing moisture, stains, and bacteria from entering the gaps, keeping them clean and hygienic, and extending the lifespan of the tiles. In tile grout application, filling and smoothing the grout are crucial steps. Filling the grout requires evenly injecting it into the tile gaps, ensuring they are completely filled without air bubbles or voids. Smoothing the grout ensures a smooth, even surface, flush with the tile surface, creating an aesthetically pleasing grout effect. According to authorized publication number CN220599066U, a tile grout smoothing device for decoration is disclosed, applied in the field of decoration technology, including a handle. This utility model loosens the rotating cylinder, allowing the locking rod to disengage from the locking hole due to its elasticity, and then moves the telescopic rod to the desired position. Afterwards, tighten the rotating cylinder to engage the locking rod with the locking hole, thus fixing it in place. This method allows for length adjustment, reduces usage costs, and improves practicality and applicability. By moving the sliding cylinder, the triangular groove moves, causing the locking connector to disengage from the inner wall of the scraper head under the action of the second spring. The scraper head can then be removed and replaced. The new scraper head is installed in the telescopic tube. Loosen the sliding cylinder, and the first spring causes the triangular groove to reset, locking the locking connector with the inner wall of the scraper head. This method facilitates scraper head replacement, reduces workload, and improves replacement efficiency.

[0003] Currently, when decorating a home, tiles are often used to make walls or floors more aesthetically pleasing. When tiles are laid together, gaps are created between adjacent tiles. To further beautify these gaps, grout is used to fill them. However, after filling with grout, there may be areas where there is too much or too little. In such cases, it is necessary to smooth the grout to ensure that the sealant fills the gaps perfectly. At the same time, any excess sealant should be scraped off and used for filling.

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0020] Example 1 Reference Figures 1-7 This is the first embodiment of the present invention, which provides a grout leveling device for home decoration, comprising: The basic handle assembly 1 includes a handle 10, interdigital recesses 11 for finger grip, a hanging ring 12, a connecting block 13, and a connecting seat 14. The handle 10 has a bent structure, and several interdigital recesses 11 are distributed on the surface of the handle 10. The hanging ring 12 is fixedly installed on the outer side of the bend of the handle 10. The lower end of the handle 10 is equipped with a connecting block 13, and the connecting seat 14 is slidably sleeved on the surface of the connecting block 13. The handle 10 can be used in the normal position to provide a point of force for the hand when the grout is smoothed. The hanging ring 12 can be hung when not in use. The interdigital recesses 11 can be used to grip the handle 10, and the finger area can be deeply fitted with the handle 10. The connecting block 13 and the connecting seat 14 are connected to facilitate the installation of different sizes of knife holders 20 with the handle 10. The blade assembly 2 includes a blade holder 20 and a scraper 21. The blade holder 20 is embedded and fixedly installed with the connecting seat 14. The scraper 21 for smoothing the grout is slidably inserted inside the blade holder 20. The scraper 21 can remove impurities and fill and smooth the grout in the grouting area. The blade holder 20 and the scraper 21 are detachable structures, so that if only the scraper 21 is damaged, it can be removed without replacing the blade holder 20.

[0021] The connecting block 13 has a pin groove 15 on its surface. A locking pin 16 is slidably sleeved inside the pin groove 15. The end of the locking pin 16 has a curved structure. A spring 17 is installed inside the pin groove 15. The two ends of the spring 17 are fixedly installed to the end face of the locking pin 16 and the inner wall of the pin groove 15, respectively. The spring 17 can ensure the stability of the extension and resetting of the locking pin 16. The locking pin 16 has a built-in locking structure. By compressing and resetting the spring 17, the locking pin 16 fits into the arc groove 18 to complete the locking and fixing.

[0022] The inner wall of the connecting seat 14 is provided with an arc-shaped groove 18, and the inside of the arc-shaped groove 18 is provided with an arc-shaped concave. The end surface of the locking pin 16 slides and abuts against the arc-shaped concave of the arc-shaped groove 18. When the tool holder 20 needs to be replaced, the end surface of the locking pin 16 slides and contacts the arc-shaped concave of the arc-shaped groove 18 through the effect of hard pulling, so that the locking pin 16 compresses the spring 17 and completely enters the pin groove 15, thereby allowing the connecting block 13 and the connecting seat 14 to be completely separated.

[0023] The tool holder 20 has threaded sleeves 22 fixed through both ends on one side. The internal threads of the threaded sleeves 22 are fitted with threaded knobs 23 for manual turning. The surface of the scraper 21 has through holes 24 corresponding to the position of the threaded sleeves 22. The inward end of the threaded knob 23 is inserted through the inner wall of the through hole 24. When the scraper 21 needs to be disassembled, the threaded knob 23 is rotated to move it threadedly with the threaded sleeves 22 and slide off the through hole 24, thus separating the scraper 21 from the tool holder 20.

[0024] The handle 10 has an extension handle assembly 3 at its tail. The extension handle assembly 3 includes a threaded seat 30, a connecting rod 31, and an external thread 32. The end of the threaded seat 30 is fixedly located on the end surface of the handle 10. The connecting rod 31 is inserted into the threaded seat 30. The connecting rod 31 has an external thread 32 on its surface near the threaded seat 30. The external thread 32 and the internal thread of the threaded seat 30 are threaded together. When it is necessary to increase the hand-holding distance, the handle 2 34 can be connected to the handle 10 by threading the external thread 32 on the connecting rod 31 with the threaded seat 30. This extends the length of the entire handle and allows for operation at high places or inconvenient distances where the body cannot easily reach.

[0025] Among them, the end of the connecting rod 31 away from the handle 10 is slidably sleeved with a sleeve 33, and the surface of the sleeve 33 is wrapped and fixed with a handle 2 34. The handle 2 34 has a corrugated structure. The corrugated structure design can play a non-slip effect when holding the hand. The sleeve 33 and the connecting rod 31 can extend and retract, which can further improve the adjustment of the extended hand holding distance.

[0026] The sleeve 33 has a positioning ring 301 fixedly installed on its end face via a bracket. The positioning ring 301 has a positioning pin 302 slidably sleeved inside. The surface of the positioning pin 302 is wound with a second spring 303. The two ends of the second spring 303 are fixedly installed to the end face of the positioning ring 301 and the end of the positioning pin 302, respectively. The second spring 303 can ensure the stable extension and resetting of the positioning pin 302. The positioning pin 302 has a hand-pulled structure, which is simple and quick to operate.

[0027] The connecting rod 31 has several parallel positioning slots 304 on its surface. The end of the positioning pin 302 away from the second spring 303 is inserted into any corresponding positioning slot 304. When the sleeve 33 and the connecting rod 31 need to be extended or retracted, the positioning pin 302 is pulled, so that the positioning pin 302 can be separated from the current positioning slot 304 by the stretching of the second spring 303. After the connecting rod 31 and the sleeve 33 are extended or retracted, the positioning slot 304 in the new position corresponds to the position of the positioning pin 302. Through the reset effect of the second spring 303, the positioning pin 302 is inserted into the positioning slot 304 in the new position, thus completing the position fixation of the connecting rod 31 and the sleeve 33 after extension or retraction.

[0028] In practical implementation: The basic handle assembly 1 of this solution includes a handle 10, whose bent structure design, combined with the finger-indentation 11 distributed on the surface, allows the user's fingers to naturally fit when holding the handle, providing a stable point of force and preventing slippage during operation. The connecting block 13 at the lower end of the handle 10 slides into the connecting seat 14, and is automatically locked in place by the locking pin 16 in the pin groove 15 and the spring 17. The end of the locking pin 16 has a curved surface structure, which slides and abuts against the arc-shaped groove 18 on the inner wall of the connecting seat 14. The spring 17... The device maintains a stable connection under the reset action, ensuring that the blade assembly 2 does not loosen during the grout smoothing process. The blade assembly 2 includes a blade holder 20 and a scraper 21. The blade holder 20 is embedded and fixed with the connecting seat 14. The scraper 21 can be slidably inserted into the blade holder 20 to remove impurities in the grout area and smooth the grout. When the scraper 21 is damaged, it can be replaced separately without replacing the entire blade holder 20, which improves the practicality and economy of the device. The hanging ring 12 is set on the outside of the handle 10 bend, which is convenient for hanging and storing when not in use, keeping the work area clean. A threaded sleeve 22 is fixed through one side of the blade holder 20 of the blade head assembly 2. A threaded knob 23 is installed inside the threaded sleeve 22. The scraper 21 has a through hole 24 corresponding to the position of the threaded sleeve 22. When the scraper 21 needs to be disassembled or replaced, the user manually rotates the threaded knob 23 to move it threadedly inside the threaded sleeve 22 and disengage it from the through hole 24, thereby easily separating the scraper 21 and the blade holder 20. This detachable structure not only facilitates maintenance but also allows for the selection of different specifications of scrapers 21 according to the grouting task, improving adaptability. At the same time, the connecting block 13 and the connecting seat 14 in the basic handle assembly 1 are quickly connected and separated by the locking pin 16 and the arc groove 18. When replacing the blade holder 20, the user applies a pulling force to make the end curved surface of the locking pin 16 slide into the arc groove 18, and the compression spring 17 enters the pin groove 15 to achieve complete separation of the connecting block 13 and the connecting seat 14. The extended handle assembly 3 includes a threaded seat 30 fixed to the tail of the first handle 10. A connecting rod 31 is inserted into the threaded seat 30. The surface of the connecting rod 31 has an external thread 32, which is threaded into the internal thread of the threaded seat 30, thereby connecting the second handle 34 to the first handle 10 and extending the overall handle length. This allows the user to perform grouting operations at high places or inaccessible areas, improving work efficiency and safety. A sleeve 33 is slidably sleeved on the end of the connecting rod 31 away from the first handle 10. The surface of the sleeve 33 is covered and fixed with the second handle 34, which has a corrugated structure. The corrugated design provides a non-slip effect, ensuring a stable grip. The end face of the sleeve 33 is fixed to the positioning ring 301 by the bracket. The positioning pin 302 is slidably sleeved inside the positioning ring 301. The second spring 303 is wrapped around the surface of the positioning pin 302, and its two ends are fixed to the end face of the positioning ring 301 and the end of the positioning pin 302 respectively, so as to ensure the stability of the extension and resetting of the positioning pin 302. When the user pulls the positioning pin 302, the second spring 303 can be compressed to separate it from the positioning groove 304 on the surface of the connecting rod 31. Then, the extension and resetting position of the sleeve 33 and the connecting rod 31 can be adjusted. When the positioning groove 304 in the new position is aligned, the second spring 303 resets and pushes the positioning pin 302 to insert, thus completing the fixing.
