Description

TECHNICAL FIELD

[0001] The application relates to the technical field of buildings, in particular to a glue nozzle of a glue gun for building engineering. BACKGROUND

[0002] In building engineering, a glue nozzle is usually used for convenient glueing treatment. The glue nozzle is divided into a plastic glue nozzle and a stainless steel glue nozzle. The plastic glue nozzle is relatively cheap, light in weight, convenient to use, and is more suitable for general home decoration and handcrafting scenes. For example, the plastic glue nozzle matched with a common glass glue gun can meet the basic glueing requirements in use, such as sealing window gaps. The stainless steel glue nozzle is more solid and durable, is not easy to deform, and can be repeatedly used, and is suitable for some occasions with high requirements on the durability of the glue nozzle, such as building construction and industrial production. In the sealing glue construction of the outer wall of a building, the stainless steel glue nozzle can better withstand large glueing pressure, and guarantee the quality and efficiency of glueing.

[0003] Through retrieval, the glue nozzle of the glue gun for building engineering disclosed by Chinese Patent Publication No. CN 219816897 U comprises a connecting end and a glue outlet pipe. The glue outlet pipe is divided into a flat pipe section and a tapered pipe section from back to front. The flat pipe section is fixed with a reinforcing rib on a flat outer side wall. The glue nozzle can be applied to various working condition requirements in building construction. When glueing is needed to be performed through a small glue outlet, the glue outlet is cut on the tapered pipe section, the discharged glue tends to be cylindrical, which is beneficial to the glue entering the gap and ensuring sufficient glue amount. When glueing is performed through a large glue outlet, the glue outlet in the shape of a duckbill can be cut on the flat pipe section without complex operations such as heating and extruding the glue nozzle, which is convenient, fast, time-saving and labor-saving, and has low operation requirements. Since the flat pipe section is prefabricated and formed, the glue discharged by the glue nozzle is more balanced and full, and the line type is more beautiful, compared with the duckbill-shaped glue outlet which is manually pressed and trimmed.

[0004] In view of the related technologies in the above, the inventors find that the existing glue nozzle of the glue gun is prone to loosening after being fixed, which causes the internal glue to overflow. Meanwhile, the traditional glue nozzle cannot be used for a long time and needs to be frequently replaced. The internal part of the glue nozzle cannot be opened, which is inconvenient for cleaning. CONTENT OF THE UTILITY MODEL

[0014] In summary, the application has the following beneficial technical effects:

[0015] This utility model incorporates two sets of fasteners and two sets of fixing grooves. The fasteners slide within the fixing grooves, allowing the upper and lower fixing tubes to connect as a single unit. Furthermore, the insertion of the inner tube enhances the sealing performance after connection and facilitates disassembly for cleaning, thus improving subsequent use and extending the lifespan of the nozzle.

[0016] This invention features a sealing plate at the bottom of the connector, which contacts the inner wall of the rotating bearing sleeve to prevent glue from overflowing from the connection point, ensuring cleanliness around the nozzle during use. The beveled top of the nozzle ensures tight contact between the nozzle and the force-bearing surface, preventing the internal glue from coming into contact with corners of the wall and making it impossible to apply glue, thus increasing the practicality of the nozzle.
