A positioning and troweling device for caulking

Abstract

This invention provides a positioning and finishing device for applying sealant and grouting, comprising a fixing sleeve and a positioning and finishing blade. The fixing sleeve has a two-section structure consisting of a sleeve head and a clamp. Rectangular protrusions are evenly distributed on the outer circumference of the sleeve head, and each rectangular protrusion has a rectangular hole. The positioning and finishing blade is made of a hard material and consists of a straight section, an angled section, and a blade head. The fixing sleeve is fitted onto the body of the sealant gun, with a retaining ring at the front end of the fixing sleeve resting against the top of the gun body, and the clamp fitting onto the gun body. The positioning and finishing blade is inserted into the rectangular hole. By adjusting the depth of insertion into the rectangular hole, the position of the blade head and the sealant nozzle is adjusted. A serrated protrusion on one side of the straight section of the positioning and finishing blade prevents it from slipping out of the rectangular hole. When applying silicone or structural adhesive, the blade head rests against the two side walls of the seam, ensuring the sealant nozzle of the sealant gun is accurately positioned at the grouting location. The blade head moves with the sealant gun to perform finishing and finishing. Positioning and finishing blades with different blade heads can be interchanged to adapt to different types of grouting.

Description

Technical Field

[0001] This invention relates to a positioning and finishing device for applying sealant to grout joints. It is suitable for use in construction and decoration projects where a caulking gun is used to inject silicone or structural adhesive into joints such as internal corners and horizontal joints to seal them. This invention enables the nozzle to accurately position itself at the joint when applying sealant with a caulking gun, and to smooth the surface of the sealant applied to the joint, improving the appearance quality of the grout application, reducing material waste, and increasing the efficiency of the grouting process. Background Technology

[0002] Applying sealant to joints formed during building decoration construction, including internal corner joints and flat joints, involves using a caulking gun to apply silicone or structural adhesive into the joints for grouting and finishing. This is a common construction operation in building decoration. The quality of joint caulking and grouting depends mainly on whether the caulking gun is aligned with the joint and whether the sealant is accurately applied. It also depends on whether the sealant surface formed after being squeezed from the cartridge is smooth and aesthetically pleasing. Both of these factors greatly depend on the skill level of the caulking worker. If the worker's skill level is low, not only will the quality of the caulking and grouting be compromised, but it will also waste a lot of materials and reduce construction efficiency. Summary of the Invention

[0003] This invention provides a positioning and finishing device for applying caulking glue, comprising a fixing sleeve and a positioning and finishing blade. The fixing sleeve is fitted onto the body of a caulking gun, with a retaining ring at the front end of the fixing sleeve resting against the top of the gun body, and a clamp fitted onto the gun body. The positioning and finishing blade, consisting of a straight section, an angled section, and a blade head, is inserted into a rectangular hole in a rectangular boss on the outer circumference of the fixing sleeve. By adjusting the depth of insertion into the rectangular hole, the position of the blade head and the glue nozzle is adjusted. A serrated protrusion on one side of the straight section of the positioning and finishing blade prevents it from slipping out of the rectangular hole. During caulking, the blade head presses against the two side walls of the seam, ensuring the glue nozzle of the caulking gun is accurately positioned at the caulking location. The blade head moves with the caulking gun to perform finishing and finishing. Positioning and finishing blades with different blade heads can be replaced to adapt to different types of caulking.

[0004] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0005] A positioning and grouting device for applying grout consists of a fixing sleeve and a positioning and grouting knife.

[0006] The fixing sleeve consists of a two-section structure consisting of a sleeve head and a sleeve clamp. The sleeve head is made of rigid material, and the inner diameter of the sleeve head is the same as the outer dimension of the glue gun body used with it. Rectangular bosses are evenly distributed on the outer circle of the sleeve head and are integrally formed with the sleeve head. The rectangular bosses have rectangular holes. A retaining ring is provided at the front end of the sleeve head. The retaining ring is integrally formed with the sleeve head, and the inner diameter of the retaining ring is smaller than the outer dimension of the glue gun body used with it.

[0007] The sleeve is made of soft rubber and is elastic; the sleeve is glued to the rear end of the sleeve head opposite the retaining ring; the inner diameter of the sleeve is slightly smaller than the outer dimensions of the glue gun body when in the free state.

[0008] The positioning trowel is made of a hard material and consists of three sections: a straight section, an angled section, and a blade head. The cross-sectional dimensions of the straight and angled sections are the same as the dimensions of the rectangular hole of the rectangular boss. The length of the straight section is greater than the length of the sleeve. One side of the straight section has serrated protrusions, which prevent the positioning trowel from slipping out of the rectangular hole after the straight section is inserted, keeping it in a fixed position. The angled section is connected to the straight section at an angle. The length of the angled section and its angle with the straight section are such that when the device is mounted on the gun body and the straight section is adjusted to its foremost position within the rectangular hole of the rectangular boss, the tip of the blade head is located diagonally in front of the nozzle tip. A set of positioning trowels with different blade head shapes are used for joints such as inside corners and flat joints, with the blade head connected to the other end of the angled section.

[0009] Before application, the fixing sleeve is placed on the caulking gun body, and the retaining ring of the sleeve head is positioned on the end face of the gun body. The elasticity of the sleeve ensures that the device tightly holds the caulking gun body. The positioning trowel is inserted into the rectangular hole of the rectangular boss. The depth of insertion into the rectangular hole is adjusted so that the position of the trowel head and the nozzle is adapted to the needs of the caulking operation. The serrated protrusions on the straight section prevent the positioning trowel from sliding out of the boss hole, keeping its position fixed. During caulking, the trowel head is pressed against the two side walls of the seam, so that the caulking gun nozzle is accurately positioned at the position to be grouted. The trowel head moves with the caulking gun to smooth and trim the surface.

[0010] Furthermore, the positioning and grouting blades of this device can be replaced with different blades depending on the type of grout to be filled, such as inside corner seams or flat seams.

[0011] Furthermore, by swapping the positioning trowel and inserting it into the rectangular holes of different rectangular bosses, it can adapt to the grouting and caulking operations required in different spatial positions.

[0012] Furthermore, the depth to which the positioning trowel is inserted into the boss hole is adjusted to accommodate different nozzle lengths, thereby adjusting its positional relationship with the nozzle.

[0013] The beneficial effects of this invention are:

[0014] This invention provides a positioning and smoothing device for applying caulking glue to seams. When applying caulking glue with a caulking gun, the nozzle can accurately position the seam and smooth the glue surface applied to the seam, thereby improving the appearance quality of the caulking glue, reducing material waste in the caulking glue operation, and increasing the efficiency of the caulking glue operation.
