Building sealant nozzle

Abstract

The invention provides a building sealant nozzle. The building sealant nozzle comprises a conical pipe-shaped base, and a replacement head inserted in a conical end of the base; a positioning piece for clamping a sharp mouth at the head end of a sealant container is arranged on the inner wall of the base; multiple auxiliary support parts with different heights are arranged on the outer wall of the base; a positioning hole for accommodating the sharp mouth at the head end of the sealant container is formed in the center of the positioning piece; and the positioning hole and the center of the base are concentrically arranged. Different replacement heads can be mounted on the base according to different working conditions, and one head achieves multiple purposes, so that the tool investment cost is low, and the use effect is good. The building sealant nozzle has a support positioning mechanism for assisting positioning by operators, so that the sealant coating is stable and reliable, and the high-quality coating of the sealant can be realized under multiple working conditions. A scraper can be arranged at the front end of the replacement head for further assisting improvement of the sealant coating effect to guarantee smooth and beautiful sealant coating.

Description

technical field [0001] The invention belongs to the technical field of sealant coating tools and accessories, in particular to a construction sealant nozzle. Background technique [0002] Sealants are often used to fill the gaps in the assembly parts of parts to achieve sealing and fix parts. Since sealants are usually stored in plastic bottles, when applying sealants, a small part of the top of the gun head needs to be manually cut off. The tip of the gun head of the glue bottle squeezes out the sealant, and when the sealant is extruded, the gun head is moved to apply the sealant to the corresponding part along the track of the gun head of the bottle mouth. The above operation method cuts off a small part of the tip of the gun head at random, and requires secondary processing, which is not conducive to use. The speed at which the sealant is extruded is uneven, and the speed of moving the gun head is difficult to ensure a uniform speed. When the glue is extruded, it is in a...

Problems solved by technology

The above operation method cuts off a small part of the tip of the gun head at random, and requires secondary processing, which is not conducive to use. The speed at which the sealant is extruded is uneven, and the speed of moving the gun head is difficult to ensure a uniform speed. When the glue is extruded, it is in any shape, which leads to uneven application of the glass glue. When the sealant is applied again later, because the sealant extruded in the early stage is columnar and has different thicknesses, there is no professional tool when applying the sealant. The amount of glue attached to the glued surface is different, the width is different, time-consuming, laborious, and material-intensive, affecting the appearance, and the bonding strength is unevenly distributed

Generally, only skilled workers with long working years can construct a uniform and beautiful glue layer, which is technically difficult and has many restrictions. Moreover, under different working conditions, such as when installing windows, seal the perimeter of the window perpendicular to the wall; or The installation of flat butt-joint glass; or the construction of complex curved surfaces, as well as some narrow gaps or corners of gaps, often lead to difficulties in gluing operations, insufficient gluing or uneven thickness of the glue, which affects the quality of gluing. Both The glue gun needs to be constructed at different inclination angles, the construction is difficult, and if it is slightly unstable, there will be defects of uneven glue quantity
