Description

Technical Field

[0001] This utility model belongs to the field of glue gun technology, and more specifically, it relates to a high-sensitivity, low-wear manual glue gun. Background Technology

[0002] A manual glue gun is a tool used for manual operation, typically for precisely applying or injecting glue, sealant, or other adhesives to desired locations. It expels glue or other substances manually and is widely used in home repairs, crafts, construction, and automotive repair.

[0003] Based on the above, the inventors have discovered the following problems: In the use of existing manual glue guns, the nozzle of most glue guns will wear out due to excessive contact with the filling surface. The more wear occurs, the larger the opening of the nozzle becomes. When filling gaps or performing precision repairs, too much glue is easily leaked out, which in turn affects the precision of the repair.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings to provide a highly sensitive, low-wear manual glue gun, in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose and effect of this utility model, a highly sensitive, low-wear manual glue gun, are achieved by the following specific technical means:

[0006] A highly sensitive, low-wear manual glue gun includes a gun body, which includes a trigger handle, a barrel, a push rod, a glue container, and a nozzle. The nozzle is movably mounted on the glue container. A pair of threaded rods are installed at one end of the barrel. A wear-resistant nozzle is movably mounted on the end of the pair of threaded rods located at the nozzle. The wear-resistant nozzle is fitted around the nozzle and has a glue outlet. The wear-resistant nozzle has a wear-resistant layer.

[0007] Furthermore, the wear-resistant nozzle has a pair of bevels on both sides of the dispensing port.

[0008] Furthermore, the wear-resistant nozzle is made of alumina.

[0009] Furthermore, the wear-resistant layer is made of an alumina coating.

[0010] Furthermore, a pair of threaded sleeves are threadedly fitted onto the pair of threaded rods, and an mounting plate is movably installed between the pair of threaded sleeves, the mounting plate being movably connected to the wear-resistant nozzle.

[0011] Furthermore, a pair of connecting posts are installed at both ends of the threaded sleeve, and the connecting posts are rotatably connected to the threaded sleeve through a hinge.

[0012] Furthermore, the mounting plate is provided with threaded holes, and one end of the wear-resistant nozzle is provided with a threaded groove, and the wear-resistant nozzle is threadedly connected to the threaded hole through the threaded groove.

[0013] Furthermore, the nozzle is threadedly connected to the glue container.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The wear-resistant nozzle is fitted around the nozzle to protect it, preventing excessive friction during contact from causing the nozzle to open too wide, thus avoiding excessive glue leakage and improving repair precision.

[0016] The angled design on the wear-resistant nozzle helps to distribute the glue more evenly, preventing excessive or uneven glue flow; it also ensures a stable flow of glue during application, avoiding waste or uneven application.

[0017] The wear-resistant nozzle is made of alumina, which is hard, wear-resistant, and relatively inexpensive, making it suitable for ordinary wear conditions. The nozzle is coated with a wear-resistant layer, and the alumina coating has good wear resistance and low cost.

[0018] By rotating the threaded sleeve, it moves towards the threaded rod, simultaneously causing the wear-resistant nozzle on the mounting plate to approach and fit against the nozzle, protecting it and preventing wear. The wear-resistant nozzle is threaded into the threaded hole, and can be removed by rotating it, allowing for replacement with nozzles of different diameters, thus improving adaptability and practicality.

The wear-resistant nozzle 6 is fitted around the nozzle 5 and has a glue outlet 12. The wear-resistant nozzle 6 has a wear-resistant layer 15. By fitting the wear-resistant nozzle 6 around the nozzle 5, the nozzle 5 is protected, preventing the nozzle 5 from opening too wide due to excessive friction during contact, thus avoiding excessive glue leakage and improving repair precision.

[0031] The wear-resistant nozzle 6 has a pair of bevels 13 on both sides of the glue outlet 12. The bevels 13 on the wear-resistant nozzle 6 help people to distribute the glue more evenly and prevent the glue from flowing out too much or unevenly.

[0035] The threaded sleeve 8 is equipped with a pair of connecting posts 14 at both ends. The connecting posts 14 are rotatably connected to the threaded sleeve 8 through a hinge. By rotating the threaded sleeve 8, it moves onto the threaded rod 7, which simultaneously drives the wear-resistant nozzle 6 on the mounting plate 9 to approach and fit against the nozzle 5, thus protecting the nozzle 5 and preventing it from being worn.

[0036] The mounting plate 9 is provided with a threaded hole 10, and one end of the wear-resistant nozzle 6 is provided with a threaded groove 11. The wear-resistant nozzle 6 is threadedly connected to the threaded hole 10 through the threaded groove 11.
