Description

Technical Field

[0001] This utility model relates to the field of decoration tools technology, and in particular to a grout injection nozzle for filling and leveling grout seams. Background Technology

[0002] Grout application refers to a construction process where grout is injected into the gaps between tiles or stone using a special caulking gun. In practice, the caulking gun is first inserted into the tube and the tip is cut off. Then, the gun is moved evenly along the tile joint while slowly squeezing the trigger, causing the grout to be expelled from the nozzle at a uniform rate, filling the joints completely. During the application process, the caulking gun must be kept stable and the movement speed consistent to ensure the grout fills the gaps completely and thoroughly, avoiding problems such as air pockets, insufficient grout, or overflow. After application, any remaining grout on the tile surface should be cleaned with a sponge, and the edges of the joints should be trimmed to ensure a smooth and aesthetically pleasing finish.

[0003] In the existing grout injection process, the direct use of the caulking gun's injection tube often results in poor adhesion between the tube and the tile grout lines, leading to excessive grout overflow, material waste, and increased manual cleaning workload. Furthermore, the difficulty in precisely controlling the injection amount often results in an uneven grout surface, failing to achieve a flush finish with the tile surface. This not only affects aesthetics but also easily accumulates dust and dirt in the gaps, causing inconvenience for daily cleaning. Utility Model Content

[0004] One objective of this invention is to provide a grout injection nozzle that fully fills and evens grout lines. This invention addresses the problems mentioned in the background regarding existing grout injection processes. Because the injection tube of a caulking gun is used directly for application, the adhesion between the tube and the tile grout lines is often poor, leading to excessive grout overflow, material waste, and increased manual cleaning burden. Furthermore, due to the difficulty in precisely controlling the injection amount, the surface of the filled grout is often uneven, failing to achieve a flush grout line with the tile surface. This not only affects aesthetics but also easily accumulates dust and dirt in the grout lines, causing inconvenience for daily cleaning.

[0005] A grout filling nozzle according to an embodiment of the present invention includes:

[0006] The mounting component is installed on the dispensing tube in the glue gun to facilitate easy assembly and disassembly. The mounting component includes a positioning sleeve that fits onto the outside of the dispensing tube. A collar is engaged on the outside of the positioning sleeve, and a fixing component is provided on the top of the collar for fixing the positioning sleeve and the dispensing tube.

[0007] The grout sealing component is installed at the front end of the positioning sleeve in the installation component to improve the smooth seam effect. The grout sealing component includes a scraper that rotates at the front end of the positioning sleeve via a rotating shaft. An inner liner is fitted inside the scraper, and a positioning glue outlet is fitted inside the inner liner.

[0008] The reset component, installed at the tail end of the scraper in the grout assembly, is used to reset the grout when removed.

[0009] Preferably, an inner liner is fixedly installed at the tail end of the positioning sleeve.

[0010] Preferably, the positioning sleeve is made of stainless steel.

[0011] Preferably, the fixing component includes a fixing seat fixed to the top of the collar, a screw threaded inside the fixing seat, a knob fixedly fixed to the top of the screw, and a rubber pad fixedly fixed to one end of the screw corresponding to the glue injection tube.

[0012] Preferably, a wear-resistant pad is engaged between the scraper and the inner liner, and the inner liner is made of silicone.

[0013] Preferably, the scraper is made of stainless steel and the slope of the scraper is 50°.

[0014] Preferably, the positioning dispensing port is made of steel, and the inner liner has a through hole that communicates with the positioning dispensing port, and the through hole is adapted to the dispensing port of the dispensing tube.

[0015] Preferably, the reset assembly includes a V-shaped buckle that rotates at the tail end of the scraper and a positioning seat fixed to the lower outer side of the positioning sleeve, wherein a tension spring is provided between the V-shaped buckle and the positioning seat.

[0016] The beneficial effects of this utility model are:

[0017] This invention effectively avoids the problems of grout waste and difficulty in achieving a smooth grout effect by setting up installation components and grout sealing components. In use, the positioning sleeve is fitted onto the outside of the glue gun's injection tube. By rotating the knob on the top of the collar, the screw is driven to move downward, so that the rubber pad at the bottom presses against the wall of the injection tube, ensuring that the positioning sleeve is securely installed. When injecting grout, the grout enters the grout sealing component from the injection tube through the front end of the positioning sleeve, and is precisely guided out through the steel positioning outlet. During construction, the scraper can rotate adaptively around the axis, so that the silicone inner liner, together with the 50° slope of the scraper, can closely fit the edge of the tile gap. When the glue gun moves, the inner liner simultaneously scrapes the overflowing grout. Its flexible properties can both fill the gap and scrape off excess glue. Combined with the wear-resistant pad to reduce wear, it ultimately forms a full-fill smooth grout effect flush with the tile surface, significantly reducing material waste and the burden of later cleaning. Moreover, the smooth surface is less prone to dirt accumulation.

[0018] This invention effectively avoids the inconvenience of subsequent operations caused by the displacement of the scraper by setting a reset component. When the nozzle needs to be lifted after completing the construction of a section of the gap, the scraper rotates around the axis under the action of external force. At this time, the positioning seat fixed to the outside of the positioning sleeve pulls the V-shaped buckle at the tail end of the scraper through the tension spring, so that the scraper automatically rebounds to the initial vertical position after leaving the tile surface. This ensures that the scraper and the inner liner can quickly return to the standard working angle each time the glue is reapplied, without the need for repeated manual adjustments, thus improving the continuity and efficiency of construction. It is especially suitable for long gap operation scenarios that require frequent interruptions. Attached Figure Description

[0027] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0028] refer to Figure 1-6 A grout injection nozzle for fully filling and leveling grout joints, comprising:

[0029] Mounting component 1 is installed on the dispensing tube in the glue gun for easy assembly and disassembly. Mounting component 1 includes a positioning sleeve 101 that fits onto the outside of the dispensing tube. A collar 103 is engaged on the outside of the positioning sleeve 101. A fixing component is provided on the top of the collar 103 for fixing the positioning sleeve 101 and the dispensing tube. The fixing component includes a fixing seat 104 fixed to the top of the collar 103. A screw 105 is threaded inside the fixing seat 104. A knob 106 is fixed on the top of the screw 105. A rubber pad 107 is fixed on the bottom of the screw 105 corresponding to one end of the dispensing tube. When the positioning sleeve is fitted onto the outside of the dispensing tube of the glue gun, the screw is driven to move downward by rotating the knob on the top of the collar, so that the rubber pad at the bottom presses against the wall of the dispensing tube, ensuring that the positioning sleeve is securely installed.

[0030] The grout sealing component 2 is installed at the front end of the positioning sleeve 101 in the installation component 1 to improve the smooth grout effect. The grout sealing component 2 includes a scraper 201 that rotates at the front end of the positioning sleeve 101 via a rotating shaft 202. An inner liner 205 is fitted inside the scraper 201, and a positioning outlet 206 is fitted inside the inner liner 205. During the application of grout, the grout enters the grout sealing component through the injection tube and the front end of the positioning sleeve. It is then precisely guided out through the steel positioning outlet. During the construction process, the scraper can rotate adaptively around the rotating shaft, so that the silicone inner liner, in conjunction with the 50° slope of the scraper, fits tightly against the edge of the tile gap. When the caulking gun moves, the inner liner simultaneously scrapes the overflowing grout. Its flexible properties can both fill the gap and scrape off excess grout. Combined with the wear-resistant pad to reduce wear, it ultimately forms a fully filled smooth grout effect that is flush with the tile surface.

[0031] The reset component 3 is installed at the tail end of the scraper 201 in the grout assembly 2. It is used to reset the scraper when it is removed. The reset component 3 includes a V-shaped buckle 301 that rotates at the tail end of the scraper 201 and a positioning seat 302 fixed to the lower outer side of the positioning sleeve 101. A tension spring 303 is provided between the V-shaped buckle 301 and the positioning seat 302. When the nozzle needs to be lifted after completing the construction of a section of the grout, the scraper rotates around the axis under the action of external force. At this time, the positioning seat fixed to the outside of the positioning sleeve pulls the V-shaped buckle at the tail end of the scraper through the tension spring, so that the scraper automatically springs back to the initial vertical position after it is removed from the tile surface. This ensures that the scraper and the inner liner can quickly reset to the standard working angle each time the grout is reapplied.

[0032] Example 1: An inner bushing 102 is fixedly installed at the tail end of the positioning sleeve 101. The positioning sleeve 101 is made of stainless steel, which enhances the wear resistance and service life of the positioning sleeve 101. The scraper 201 is made of stainless steel, and the slope of the scraper 201 is 50°.

[0033] Example 2: A wear-resistant pad 204 is engaged between the scraper 201 and the inner liner 205, further improving the wear resistance of the nozzle during use. The inner liner 205 is made of silicone, which has good elasticity and sealing properties, ensuring good adhesion to the tile gaps. The positioning outlet 206 is made of steel. The inner liner 205 has a through hole that communicates with the positioning outlet 206. The through hole is adapted to the outlet of the glue injection tube, which can accurately control the amount and direction of the grout.

[0034] Working principle: First, the positioning sleeve 101 of the installation component 1 is fitted onto the outside of the glue gun's injection tube. Then, the knob 106 on the top of the collar 103 is rotated, driving the screw 105 to move downwards. The rubber pad 107 at its bottom presses against the wall of the injection tube, achieving a stable fixation between the positioning sleeve 101 and the injection tube, ensuring stability and sealing during the glue injection process. Next, the scraper 201 of the grout tile component 2 is installed at the front end of the positioning sleeve 101. The inner lining 205 of the scraper 201 engages with the wear-resistant pad 204. The inner lining 205 has a through hole that communicates with the steel positioning glue outlet 206. This through hole matches the glue outlet of the injection tube. During glue injection, the grout enters the grout tile component 2 from the injection tube through the front end of the positioning sleeve 101, and is precisely guided and output to the tile gaps through the positioning glue outlet 206. During the application process, the scraper 201 can rotate adaptively around the pivot 202. The silicone inner liner 205 on its inner side fits tightly against the edge of the tile grout with the 50° slope of the scraper. As the glue gun moves, the inner liner 205 simultaneously scrapes and smooths out the overflowing grout, using its flexible properties to fill the gaps and scrape away excess glue. Combined with the wear-resistant pad 204 to reduce wear, it ultimately forms a fully filled grout effect flush with the tile surface. When the glue nozzle needs to be lifted after completing a section of the grout application, the scraper 201 rotates around the pivot 202 under the action of external force. At this time, the V-shaped buckle 301 in the reset assembly 3 cooperates with the positioning seat 302 under the traction of the tension spring 303, so that the scraper 201 automatically springs back to the initial vertical position after leaving the tile surface, ensuring that the scraper 201 and the inner liner 205 can quickly return to the standard working angle each time glue is reapplied.
