For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Example 1

[0024] See Figures 1 to 4 This utility model provides a waterproof coating application tool for external wall bolt holes, including a handle 1, an installation ring 2 fixedly mounted on the handle 1, and a storage container 3 fixedly mounted on the installation ring 2, the storage container 3 being used to store waterproof coating;

[0025] Before using this device, fill the storage container 3 with waterproof coating;

[0026] The lower end of the storage tank 3 is threadedly connected to the press nozzle 4. The press nozzle 4 includes a nozzle body 5. A nozzle 6 is installed on one side of the nozzle body 5. A trigger 7 is hinged to the side of the nozzle body 5 adjacent to the nozzle 6. The trigger 7 is connected to the piston inside the nozzle body 5.

[0027] When the trigger 7 contacts the wall, the trigger 7 is forced to drive the piston inside the nozzle body 5 to move. As the piston moves, the waterproof coating in the reservoir 3 is sprayed through the nozzle 6 onto the bolt holes and surrounding areas of the wall. If a large area needs to be sprayed, the handle 1 can be moved multiple times to make the trigger 7 contact the wall multiple times to achieve a large area of ​​spraying.

[0028] A stand 8 is fixedly mounted on the handle 1, a base 9 is fixedly mounted on the lower end of the stand 8, an adapter 10 is fixedly mounted on the base 9, and a brush 11 is fixedly mounted on the adapter 10.

[0029] After the waterproof coating is sprayed onto the wall, the brush 11 comes into contact with the wall. At this time, the trigger 7 is under continuous pressure. By continuously moving the handle 1, the brush 11 spreads the excess waterproof coating, allowing the waterproof coating to adhere more evenly to the wall, filling any tiny gaps that may exist at the bolt holes on the wall, improving the waterproof effect, and enabling the waterproof coating to better perform its waterproofing function.

[0030] The brush 11 is C-shaped, and the middle part of the brush 11 corresponds to the nozzle 6;

[0031] The open end of the brush 11 corresponds to the trigger 7 of the spray nozzle 4.

[0032] The application brush 11 ensures that the waterproof coating sprayed from the nozzle 6 is within the working range of the application brush 11, preventing the coating from being spilled into unnecessary areas, ensuring that the coating is accurately applied to the bolt holes, reducing waste, and improving material utilization. Moreover, after spraying is completed, the hand naturally transitions to the application action, allowing for continuous spraying and application operations with one hand, simplifying the construction process and improving construction efficiency.

[0033] The movable end of the trigger 7 is fixedly equipped with a trigger lever 12, and the end of the trigger lever 12 away from the trigger 7 is rotatably equipped with a trigger ball 13.

[0034] When the brush 11 comes into contact with the wall, the trigger 7 is under continuous force because the worker needs to hold the handle 1 and use the brush 11 to apply the coating to the bolt holes and their surroundings. During this process, the trigger 7 will inevitably rub and squeeze against the wall.

[0035] When the handle 1 is moved, the trigger ball 13 contacts the wall first. Compared with the trigger 7 directly contacting the wall, the ball surface and the wall form rolling friction, making the movement of the handle 1 smoother. The operator can more easily and smoothly control the tool to move along the wall surface.

[0036] This not only makes the action of applying waterproof coating to the bolt holes more continuous with the brush 11, improving the uniformity and efficiency of the coating, but also reduces the wear that the trigger 7 may experience due to frequent friction against the wall, extending the service life of the trigger 7 and the entire press nozzle 4.

[0037] An opening is provided at the upper end of the storage container 3, and the top cover 14 is threadedly connected to the opening of the storage container 3.

[0038] Users can open the top cover 14 on the storage container 3 to fill the waterproof coating into the storage container 3, and then use the top rod to seal the storage container 3 to prevent leakage during subsequent use, thus ensuring normal spraying and coating operations.

[0039] A hanging ring 15 is fixedly installed on the handle 1.

[0040] Users can hang the tool on the hook via the hanging ring 15, making it easy and safe to carry. This will not affect other operations because the tool is being held in hand, and it will also ensure that the tool will not fall off during transportation.

[0041] When using this utility model, before using the device, fill the storage container 3 with waterproof coating;

[0042] When the trigger 7 contacts the wall, the trigger 7 is forced to drive the piston inside the nozzle body 5 to move. As the piston moves, the waterproof coating in the reservoir 3 is sprayed through the nozzle 6 onto the bolt holes and surrounding areas of the wall. If a large area needs to be sprayed, the handle 1 can be moved multiple times to make the trigger 7 contact the wall multiple times to achieve a large area of ​​spraying.

[0043] After the waterproof coating is sprayed onto the wall, the brush 11 comes into contact with the wall. At this time, the trigger 7 is under continuous pressure. By continuously moving the handle 1, the brush 11 spreads the excess waterproof coating, allowing the waterproof coating to adhere more evenly to the wall, filling any tiny gaps that may exist at the bolt holes on the wall, improving the waterproof effect, and enabling the waterproof coating to better perform its waterproofing function.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
