Description

Technical Field

[0001] This invention relates to the field of adhesive injection technology for grout lines, specifically to an adhesive injection tool for grout lines. Background Technology

[0002] A caulking gun is a tool for applying caulking compound. It is used wherever caulking compound is needed and is widely used in industries such as construction and decoration, electronics, automobiles and auto parts, shipbuilding and containers. When applying caulking compound, aim the gun tip at the joint, then squeeze the caulking compound inside the gun to spray it out from the tip. While applying the compound, move the gun at a constant speed along the joint to completely fill it.

[0003] After applying the caulking gun to the joint, it is generally necessary to use the caulking gun tip to spread the caulking gun along the inside of the joint, making the caulking gun inside the joint form an arc-shaped concave shape to improve the appearance of the joint. However, this adds an extra step to the process, which not only greatly increases the workload of the workers, but also seriously delays the entire caulking process and reduces efficiency.

[0004] Based on this, the present invention designs an adhesive injection tool for adhesive joints to solve the above problems. Summary of the Invention

A second spring is fixedly connected between the upper end of the first moving block and the inner top end of the first moving block. The lower end of the first moving block can extend out of the lower port of the first sliding cavity and is located between the first arc-shaped tube and the second arc-shaped tube. A first locking groove is provided in the middle of the lower end of the first moving block. The rectangular locking block is fixedly disposed on the side of the outer wall of the first arc-shaped tube near the spherical component. The rectangular locking block can be inserted into the first locking groove. An auxiliary locking assembly for locking the pressure plate is provided in the first sliding cavity.

[0010] As a further embodiment of the present invention, the auxiliary locking assembly includes a slanted panel and a slanted protrusion.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention enables direct application of adhesive to gaps on flat surfaces and external corners via the discharge end of the curved hole on the spherical component. Simultaneously, the curved surface of the spherical component presses and shapes the adhesive within the gap, eliminating the need for subsequent seam-closing work. This significantly improves application efficiency and shortens the construction period. Furthermore, it allows for quick connection between the tapered adhesive tube and the curved hole, and enables application of adhesive to internal corner gaps via the end of the tapered tube, thus enhancing the tool's practicality and applicability.

[0017] 2. This invention automatically and quickly compresses the air bladder via a squeezing mechanism the instant the conical glue applicator tube aligns with the bend, forcing the air inside the air bladder into the annular cavity of the sealing ring. This causes the sealing ring to rapidly expand and tightly adhere to the outer surface of the spherical part, preventing glue from leaking out from the gap at the connection between the conical glue applicator tube and the bend. Before separating the conical glue applicator tube from the bend, the squeezing mechanism can be manually reset to stop compressing the air bladder, causing the sealing ring to contract and separate from the outer surface of the spherical part. This reduces the resistance of the arc-shaped sliding sleeve and the conical glue applicator tube bending upwards and avoids wear between the sealing ring and the spherical part, thereby ensuring the tool's service life and long-term sealing performance.

[0020] Please see Figure 1-6This invention provides a technical solution: a glue injection tool for caulking, comprising a glue gun body 1, a discharge pipe 2 at one end of the glue gun body 1, a spherical component 3 connected to the end of the discharge pipe 2 away from the glue gun body 1, a curved hole 4 inside the spherical component 3, the inlet end of the curved hole 4 communicating with the discharge pipe 2, an arc-shaped sliding sleeve 5 rotatably connected to the outside of the spherical component 3, a conical glue injection tube 6 fixedly connected to the outer wall of the arc-shaped sliding sleeve 5, the inlet end of the conical glue injection tube 6 communicating with the outlet end of the curved hole 4, and a sealing ring 7 fixedly connected to the inner side of the inlet end of the conical glue injection tube 6. The sealing ring 7 can contact the outer wall of the spherical part 3. An annular cavity 8 is opened on the inner side of the sealing ring 7. The outer wall of the tapered glue applicator 6 is fixedly connected to the first arc-shaped tube 9. An air bladder 10 is provided in the first arc-shaped tube 9. One end of the air bladder 10 extends into the tapered glue applicator 6 and is fixedly connected to the annular cavity 8 in the sealing ring 7. The outer wall of the spherical part 3 is provided with a squeezing mechanism for squeezing the air bladder 10 on the lower side of the feed end of the bend 4. The lower side of the spherical part 3 is provided with a first locking mechanism for locking the first arc-shaped tube 9. The upper side of the spherical part 3 is provided with a second locking mechanism for locking the arc-shaped sliding sleeve 5.

[0021] When the above solution is put into practical use, the tool has two modes. One mode involves bending the arc-shaped sleeve 5 upwards until the inlet end of the conical glue-applying tube 6 is completely separated from the outlet end of the bend 4. In this mode, glue can be applied directly through the outlet end of the bend 4 to the gaps at the flat surface and external corners. Simultaneously, the spherical component 3 moves along the gap, and the arc surface of the spherical component 3 presses the glue in the gap into a fixed shape. The other mode involves bending the arc-shaped sleeve 5 downwards until the inlet end of the conical glue-applying tube 6 connects with the outlet end of the bend 4, allowing glue to be applied through the end of the conical glue-applying tube 6. It can apply glue to the gaps in the inside corners that the spherical part 3 cannot reach; when the arc-shaped sliding sleeve 5 bends downwards to connect the feed end of the conical glue-applying tube 6 with the discharge end of the bend 4, the first locking mechanism locks the first arc-shaped tube 9, thereby fixing the conical glue-applying tube 6 to ensure a stable connection between the conical glue-applying tube 6 and the bend 4. At the same time, the extrusion mechanism automatically and quickly extrudes the air bladder 10 inside the first arc-shaped tube 9, instantly squeezing the air inside the air bladder 10 into the annular cavity 8 inside the sealing ring 7, causing the sealing ring 7 to expand instantly to make tight contact with the outer surface of the spherical part 3, so as to prevent glue from flowing out of the conical glue-applying tube. Leakage occurs at the gap between pipe 6 and bend 4; when it is necessary to bend the arc-shaped sleeve 5 upward, first manually reset the extrusion mechanism, the extrusion mechanism stops extruding the airbag 10, the airbag 10 automatically resets under its own elasticity and sucks back the air in the annular cavity 8, the sealing ring 7 quickly contracts to separate from the outer surface of the spherical part 3, after the extrusion mechanism is reset, the first locking mechanism can be automatically unlocked, the first arc-shaped pipe 9 is released, and then the arc-shaped sleeve 5 is bent upward. When the conical glue-applying pipe 6 and the first arc-shaped pipe 9 completely avoid the discharge end of the bend 4, the second locking mechanism automatically locks the arc-shaped sleeve 5, thereby making the conical glue-applying pipe 6 bend upward. The tube 6 is fixed in place so that the glue can be applied through the outlet end of the bend 4. In this way, the tool can directly apply glue to the gaps on the flat surface and at the external corner through the outlet end of the bend 4 on the spherical part 3. At the same time, the spherical part 3 can press and shape the glue in the gap through the arc surface, avoiding the need for later grouting work on the glued gaps. This significantly improves the efficiency of glue application and shortens the construction period. It also allows the tapered glue tube 6 to be quickly connected to the bend 4, and the tapered glue tube 6 can be used to apply glue to the gaps at the internal corners, thereby improving the practicality and applicability of the tool.The tool automatically and quickly squeezes the air bladder 10 the instant the conical glue applicator 6 aligns with the bend 4, forcing the air inside the air bladder 10 into the annular cavity 8 of the sealing ring 7. This causes the sealing ring 7 to rapidly expand and press tightly against the outer surface of the spherical part 3, preventing glue from leaking out from the gap at the connection between the conical glue applicator 6 and the bend 4. Before separating the conical glue applicator 6 from the bend 4, the squeezing mechanism can be manually reset to stop squeezing the air bladder 10, causing the sealing ring 7 to contract and separate from the outer surface of the spherical part 3. This reduces the resistance of the arc-shaped sliding sleeve 5 and the conical glue applicator 6 bending upwards and avoids wear between the sealing ring 7 and the spherical part 3, thus ensuring the tool's service life and long-term sealing performance.

[0022] As a further embodiment of the present invention, the extrusion mechanism includes a second arc-shaped tube 11, which is fixedly connected to the outer wall of the spherical component 3. The lower end of the second arc-shaped tube 11 can be aligned with the end of the first arc-shaped tube 9 away from the conical glue-applying tube 6. A circular slider 12 is slidably connected to the inner side of the second arc-shaped tube 11. A first spring 13 is fixedly connected between the inner top end of the second arc-shaped tube 11 and the circular slider 12. A hand-pulling assembly for manually pulling the circular slider 12 is provided on the outer side of the second arc-shaped tube 11. An arc-shaped rod 14 is fixedly connected to the lower side of the circular slider 12. The lower end of the arc-shaped rod 14 extends out of the second arc-shaped tube 11 and is fixedly connected to a pressure plate 15. The pressure plate 15 can extend into the end of the first arc-shaped tube 9 away from the conical glue-applying tube 6.

[0023] When the above scheme is put into actual use, before the tapered glue-applying tube 6 aligns with the bend 4, the pressure plate 15 is locked at the lower end of the second arc-shaped tube 11 by the first locking mechanism. When the tapered glue-applying tube 6 aligns with the bend 4, the end of the first arc-shaped tube 9 away from the tapered glue-applying tube 6 aligns with the lower end of the second arc-shaped tube 11. At the same time, the first arc-shaped tube 9 is locked by the first locking mechanism, which automatically releases the pressure plate 15. Thus, under the elastic force of the first spring 13, the circular slider 12 pushes the pressure plate 15 through the arc-shaped rod 14, causing the pressure plate 15 to instantly plunge into the first... The arc-shaped tube 9 compresses the airbag 10, causing the sealing ring 7 to expand tightly against the outer surface of the spherical part 3. When it is necessary to bend the arc-shaped sliding sleeve 5 and the conical glue-applying tube 6 upward, the circular slider 12 is first pulled upward by the hand-pulling assembly until the pressure plate 15 slides up to the reset position. After the pressure plate 15 is reset, the first locking mechanism can automatically release the first arc-shaped tube 9, so that the arc-shaped sliding sleeve 5 and the conical glue-applying tube 6 can be bent upward. After the arc-shaped sliding sleeve 5 and the conical glue-applying tube 6 are bent upward, the first locking mechanism can automatically lock the pressure plate 15 located at the lower end of the second arc-shaped tube 11.

[0024] As a further embodiment of the present invention, the hand-pulled assembly includes an arc-shaped groove 16 and a pull plate 17. The arc-shaped groove 16 is formed on the lower side wall of the second arc-shaped tube 11, and the pull plate 17 is located outside the second arc-shaped tube 11. The upper end of the pull plate 17 extends into the second arc-shaped tube 11 through the arc-shaped groove 16 and is fixedly connected to the circular slider 12.

[0025] When the above solution is put into actual use, by pulling the pull plate 17 with a finger, the pull plate 17 pulls the circular slider 12 to slide upward and compress the first spring 13. The circular slider 12 drives the pressure plate 15 to slide upward through the arc rod 14 until the pressure plate 15 slides to the lower end of the second arc tube 11, so that the first locking mechanism can automatically lock the pressure plate 15.

[0026] As a further embodiment of the present invention, the first locking mechanism includes a first sliding cavity 18 and a rectangular locking block 22. The first sliding cavity 18 is located on the lower side of the spherical component 3. A first moving block 19 is slidably connected to the inner side of the first sliding cavity 18. A second spring 20 is fixedly connected between the upper end of the first moving block 19 and the inner top end of the first moving block 19. The lower end of the first moving block 19 can extend out of the lower port of the first sliding cavity 18 and is located between the first arc-shaped tube 9 and the second arc-shaped tube 11. A first locking groove 21 is provided in the middle of the lower end of the first moving block 19. The rectangular locking block 22 is fixedly disposed on the side of the outer wall end of the first arc-shaped tube 9 near the spherical component 3. The rectangular locking block 22 can be inserted into the first locking groove 21. An auxiliary locking assembly for locking the locking pressure plate 15 is provided in the first sliding cavity 18.

[0027] When the above solution is put into actual use, when the tapered glue applicator 6 is aligned with the bend 4, the rectangular locking block 22 on the first arc-shaped tube 9 automatically releases the pressure plate 15 through the auxiliary locking assembly. Under the elastic force of the first spring 13, the pressure plate 15 rushes into the first arc-shaped tube 9 and squeezes the airbag 10. When the pressure plate 15 leaves the lower end of the second arc-shaped tube 11, the second spring 20 pushes the first moving block 19 down, so that the first slot 21 at the lower end of the first moving block 19 engages with the rectangular locking block 22, thereby locking the first arc-shaped tube 9, and thus fixing the tapered glue applicator 6 in place with the bend. The state of hole 4 being connected; when the pressure plate 15 is pulled back to the lower port of the second arc-shaped tube 11 by the manual pull assembly, the pressure plate 15 can push the first moving block 19 to slide upward through the auxiliary locking assembly, causing the first slot 21 to separate from the rectangular block 22, so that the first locking mechanism releases the first arc-shaped tube 9, thereby allowing the arc-shaped sliding sleeve 5 and the tapered glue tube 6 to bend upward. When the tapered glue tube 6 bends upward, the rectangular block 22 on the first arc-shaped tube 9 leaves the lower part of the first moving block 19. At this time, the auxiliary locking assembly automatically locks the pressure plate 15 located at the lower port of the second arc-shaped tube 11.

[0028] As a further embodiment of the present invention, the auxiliary locking assembly includes a slanted panel 23 and a slanted protrusion 25. The slanted panel 23 is slidably disposed within the first moving block 19. A third spring 24 is fixedly connected between the upper end of the slanted panel 23 and the top end of the first sliding cavity 18. The lower end of the slanted panel 23 can extend out of the lower port of the first sliding cavity 18. The slanted surface of the lower end of the slanted panel 23 can contact the side of the rectangular locking block 22 near the second arc-shaped tube 11. The side of the slanted panel 23 near the second arc-shaped tube 11 can contact the side of the pressure plate 15 away from the second arc-shaped tube 11. The slanted protrusion 25 is fixedly disposed on the lower side of the first moving block 19 near the second arc-shaped tube 11. The slanted surface of the lower end of the slanted protrusion 25 can contact the side of the pressure plate 15 near the second arc-shaped tube 11.

[0029] When the above scheme is put into actual use, when the pressure plate 15 is located at the lower end of the second arc-shaped tube 11, the third spring 24 pushes the inclined plate 23 down, causing the side of the inclined plate 23 near the second arc-shaped tube 11 to block the side of the pressure plate 15 away from the second arc-shaped tube 11, thereby locking the pressure plate 15. The pressure plate 15 locked at the lower end of the second arc-shaped tube 11, through the inclined protrusion 25, squeezes the first moving block 19 into the first sliding cavity 18. When the tapered glue tube 6 is aligned with the bend 4, the rectangular locking block 22 on the first arc-shaped tube 9 squeezes the inclined plate 23 into the first sliding cavity 18, causing the inclined plate 23 to separate from the pressure plate 15, so that the pressure plate 15 is released by the spring 13. The pressure plate 15 is quickly thrust into the first arc-shaped tube 9 and squeezes the airbag 10. When the pressure plate 15 is thrust into the first arc-shaped tube 9, the pressure plate 15 leaves the lower end of the inclined protrusion 25, allowing the first moving block 19 to slide down under the elastic force of the second spring 20, so that the first slot 21 can be inserted into the rectangular slot 22, thereby locking the first arc-shaped tube 9. When the pressure plate 15 is pulled back to the lower end of the second arc-shaped tube 11 by the hand-pulling assembly, the pressure plate 15 squeezes the first moving block 19 into the first sliding cavity 18 through the inclined protrusion 25, thereby separating the first slot 21 from the rectangular slot 22, that is, unlocking the first arc-shaped tube 9, and then allowing the arc-shaped sliding sleeve 5 and the conical glue tube 6 to bend upward.

[0030] As a further embodiment of the present invention, the second locking mechanism includes a second sliding cavity 26 and a second locking groove 30. The second sliding cavity 26 is opened on the upper side of the spherical part 3. A second moving block 27 is slidably connected in the second sliding cavity 26. A fourth spring 28 is fixedly connected between the lower end of the second moving block 27 and the bottom end of the second sliding cavity 26. An inclined block 29 is fixedly connected to the upper end of the second moving block 27 near the arc-shaped sliding sleeve 5. The inclined surface of the upper end of the inclined block 29 can contact the upper side of the arc-shaped sliding sleeve 5. The second locking groove 30 is opened on the inner wall of the arc-shaped sliding sleeve 5. The inclined block 29 can be inserted into the second locking groove 30. A push plate 31 is fixedly connected to the upper end of the second moving block 27 away from the arc-shaped sliding sleeve 5.

[0031] When the above solution is put into actual use, when the arc-shaped sliding sleeve 5 bends upward to the upper side of the spherical part 3, the upper side of the arc-shaped sliding sleeve 5 first squeezes the inclined plate 29 into the second sliding cavity 26. When the upper side of the arc-shaped sliding sleeve 5 is blocked by the push plate 31, the second slot 30 on the inner wall of the arc-shaped sliding sleeve 5 is aligned with the inclined plate 29. At this time, under the elastic force of the fourth spring 28, the inclined plate 29 automatically slides up to insert into the second slot 30, thereby locking the arc-shaped sliding sleeve 5. When it is necessary to unlock the arc-shaped sliding sleeve 5, the push plate 31 is manually pressed down, and the push plate 31 presses down the second moving block 27, causing the inclined plate 29 to retract into the second sliding cavity 26, thereby separating the inclined plate 29 from the second slot 30, and thus unlocking the arc-shaped sliding sleeve 5.

[0032] As a further embodiment of the present invention, the outer wall of the spherical component 3 is fixedly connected with an internally threaded tube 32, the internally threaded tube 32 is connected to the feed end of the bent hole 4, and the internally threaded tube 32 is threadedly connected to the discharge tube 2; during operation, the internally threaded tube 32 facilitates the installation and disassembly of the spherical component 3 and the components connected to the spherical component 3, so as to facilitate the replacement of new spherical components 3 and the components connected to the spherical component 3.

[0033] As a further embodiment of the present invention, anti-slip stripes 33 are fixedly provided on the upper surface of the push plate 31; during operation, the anti-slip stripes 33 can prevent slippage when the push plate 31 is pressed by hand.

[0034] As a further embodiment of the present invention, a guide slider 34 is fixedly connected to the middle of the inner side of the first sliding cavity 18. The guide slider 34 is slidably connected to the first moving block 19 and the inclined plate 23. In operation, the guide slider 34 makes the sliding of the first moving block 19 and the inclined plate 23 in the first sliding cavity 18 more stable.

[0035] As a further aspect of the present invention, both the sealing ring 7 and the airbag 10 are made of rubber; the sealing ring 7 and the airbag 10 made of rubber have good elasticity and sealing performance.
