Description

Technical Field

[0001] The utility model relates to the technical field of building decoration, and specifically relates to a gap filling device for building decoration. Background Technique

[0002] After the tiles are bonded, it is necessary to fill the gaps between the tiles with sealant. Filling the sealant can make the gaps between the tiles look more beautiful and can also play a role in preventing mildew and water. At present, the method of filling the sealant is that the staff needs to squat down and use a glue gun to fill the gaps between the tiles. After filling, tools such as a scraper need to be used again to scrape the sealant flat. This method is time-consuming and laborious, and at the same time, long-term work will also cause damage to the user's waist.

[0003] The utility model with the publication number of CN220521885U proposes a gap filling device for building decoration, including a bottom plate with a push rod arranged on the top, a feeding bin arranged on the top of the bottom plate, a motor arranged on the top of the feeding bin, a screw rod fixedly connected to the outside of the motor, a connecting pipe arranged at the bottom of the feeding bin, a corrugated pipe arranged at the bottom of the connecting pipe, a glue outlet head arranged at one end of the corrugated pipe away from the connecting pipe, a connecting plate arranged on the outside of the glue outlet head, several sliding rods fixedly connected to the top of the connecting plate, a sliding groove slidably connected to the outside of the sliding rods, several connecting springs fixedly connected to the top of the connecting plate, several sliding ways arranged inside the bottom plate, a support rod connected to the inside of the sliding ways, and a scraper fixedly connected to the bottom of the support rod. The utility model can facilitate the user to fill the joints, and at the same time, can make the filler discharge evenly, so as to improve the filling effect, and can also scrape the filler at the joints flat, so as to improve the use convenience.

[0004] However, the above-mentioned prior art still has the following deficiencies when in use: 1. It is not easy to control the discharge amount of the sealant, and it is easy to have the problem of too little or too much discharge of the sealant. For example, the depths of some gaps are different, and the required amounts of sealant are different. Therefore, there is a defect that it is difficult to adjust the glue discharge amount according to the gap depth, which ultimately affects the quality of gap filling; 2. The walking resistance is large. The set glue outlet head needs to be inserted into the gap, and at the same time, the connecting plate will press against the tile. Therefore, a large resistance will be formed when moving the bottom plate, and there is a problem of uneven walking speed, which affects the uniformity of sealant filling.

[0005] Therefore, the utility model provides a gap filling device for building decoration. Utility Model Content

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] In order to make the technical means, creative features, achieved purposes and functions of the utility model easy to understand, the utility model will be further described below in conjunction with the specific embodiments.

[0023] Please refer to Figures 1 to 3 , the utility model provides a technical solution: a gap filling device for building decoration, including a bottom plate 1. A glue outlet head 2 is arranged at the bottom of the bottom plate 1, and a feeding bin 3 communicated with the inner cavity of the glue outlet head 2 is arranged at the top. A screw rod 4 is arranged in the feeding bin 3. The connection mode between the glue outlet head 2 and the feeding bin 3, and the glue outlet head 2 and the screw rod 4 can adopt the structures in the patent documents mentioned in the background. A scraping plate can be installed at the rear of the bottom of the bottom plate 1 during use, and the scraping plate still adopts the structure in the prior art mentioned in the background technology.

[0024] In this technical solution, the inner cavity of the feeding bin 3 is conical with the small end facing downwards. A guiding block 5 that is slidably engaged with the feeding bin 3 up and down is fixedly arranged at the top of the screw rod 4. Specifically, during implementation, a straight pipe 31 sleeving the outside of the guiding block 5 is welded to the top of the feeding bin 3. A rubber sleeve 51 that is hermetically engaged with the straight pipe 31 is fixedly sleeved on the outer peripheral wall of the guiding block 5. One side of the guiding block 5 is fixedly connected with a pressing plate 6 located outside the feeding bin 3. When the guiding block 5 moves up and down, it can drive the screw rod 4 to move up and down in the conical inner cavity of the feeding bin 3. The top of the guiding block 5 is fixedly connected with a motor 8 whose output shaft is fixedly connected with the top of the screw rod 4. The motor 8 provides driving force for the rotation of the screw rod 4. The spiral blade 41 on the screw rod 4 is conical and has the same taper as the inner cavity of the feeding bin 3. When the spiral blade 41 moves downwards, the gap between its outer periphery and the inner conical wall of the feeding bin 3 decreases, and vice versa. When the above gap decreases, the effective driving force of the spiral blade 41 rotating on the material in the feeding bin 3 increases, and the flow rate of the material discharged from the glue outlet 2 is greater, and vice versa. Thus, this device has the function of adjusting the discharge of the glue outlet 2.

[0025] A pressing handle 7 is fixedly connected to the top of the bottom plate 1. The pressing handle 7 is an operating component for manually holding and pushing the bottom plate 1 to move on the tile surface. The pressing handle 7 is located below the pressing plate 6. This kind of setting facilitates manually pushing the pressing plate 6 downwards to increase the amount of material discharged through the glue outlet 2.

[0026] In this embodiment, a feeding pipe 311 is welded to the outer peripheral wall of the straight pipe 31. This feeding pipe 311 is the feeding port for injecting material into the feeding bin 3.

[0027] Furthermore, a transmission shaft 9 is rotatably connected to the top of the pressing handle 7. The transmission shaft 9 penetrates through and is screwed with the pressing plate 6. That is to say, the transmission shaft 9 is of a screw structure. A threaded hole that is screwed with the transmission shaft 9 is opened on the pressing plate 6. When controlling the rotation of the transmission shaft 9, the up and down movement of the guiding block 5 can be controlled. Among them, a rotating handle 91 is welded to the top of the transmission shaft 9. This rotating handle 91 is the operating component for manually controlling the rotation of the transmission shaft 9.

[0028] In this embodiment, the top of the glue outlet 2 is fixedly connected to the bottom of the bottom plate 1. The bottom of the bottom plate 1 is elastically slidably connected up and down with a V-shaped guiding wheel 101 located in front of the glue outlet 2. During use, the V-shaped guiding wheel 101 is straddled on the gap between the tiles. Under the rolling guidance of the V-shaped guiding wheel 101, the resistance of the bottom plate 1 contacting the ground and the resistance of the glue outlet 2 contacting the tile gap can be reduced.

[0029] Specifically, a sunken groove 11 is formed at the bottom of the bottom plate 1. A guiding hole 111 is formed at the bottom inside the sunken groove 11. A wheel seat 102 is arranged inside the sunken groove 11. A guiding shaft 1021 which is slidably connected to the guiding hole 111 is welded to the top of the wheel seat 102. A spring 103 located inside the sunken groove 11 is sleeved on the guiding shaft 1021. The V-shaped guiding wheel 101 is arranged at the bottom of the wheel seat 102. When the bottom plate 1 is pressed downward, the spring 103 will be compressed. At this time, the gap between the glue outlet head 2 and the tile can be aligned.

[0030] Working principle: Hold the pressing handle 7 and place the bottom plate 1 on the ground. Then place the V-shaped guiding wheel 101 on the gap between the tiles. Then start the motor 8 and manually press and push the bottom plate 1. At this time, the glue outlet head 2 will be aligned with the gap that needs to be filled with materials. Under the rolling guidance of the V-shaped guiding wheel 101, the bottom plate 1 moves forward. At the same time, the spiral blade 41 conveys the materials in the feeding bin 3 to the glue outlet head 2. The glue outlet head 2 discharges the materials into the gap. When it is found that the amount of materials discharged by the glue outlet head 2 is small at the current moving speed, the transmission shaft 9 can be rotated manually through the rotating handle 91, so that the spiral blade 41 moves downward. At this time, the extrusion area of the materials in the feeding bin 3 will be increased, and the flow rate of the materials discharged by the glue outlet head 2 will increase, thereby improving the efficiency of gap filling.

[0031] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
