Description

Technical Field

[0001] The utility model relates to the technical field of glue guns, in particular to a glue gun which is convenient for replacing glue liquid. Background Art

[0002] With the continuous improvement of living standards and aesthetic awareness, in interior decoration, more and more people will use adhesives, caulking agents, bonding glues and other glue products to fill the gaps in interior decoration and beautify the interior space.

[0003] At present, glue products are mainly glued with glue guns. Traditional glue guns are mainly composed of a tank body, a sealing cover plate, a pressing pump and a discharge pipe. The tank body is filled with glue and has an opening on the top; the sealing cover plate is sealed and fixed at the opening of the tank body and has a through hole in the middle; the pressing pump is inserted in the through hole and the discharge port on its top passes through the through hole; the discharge pipe is fixedly connected to the discharge port on the top of the pressing pump; the glue gun nozzle is detachably connected to the discharge pipe; in actual use, reciprocating pressing of the glue gun nozzle will link the discharge pipe to reciprocate pressing of the pressing pump. At this time, the pressing pump will draw out the glue contained in the tank body and spray it out through the glue gun nozzle to complete the gluing work.

[0004] However, the glue guns mentioned above mostly use tanks to directly store glue liquid. After being placed for a long time or used, the glue liquid is easy to solidify on the inner wall of the tank, which not only hinders the subsequent filling of glue liquid, but also hinders the spraying of glue liquid, causing the glue gun to be scrapped prematurely and the service life to be greatly shortened.

[0005] Therefore, how to design a glue gun that is convenient for replacing glue is a problem that technical personnel in this field urgently need to solve. Utility Model Content

[0006] The utility model provides a glue gun which is convenient for replacing glue liquid, and solves the technical problem that the glue liquid is easy to solidify on the inner side wall of the existing glue gun, resulting in the glue gun being unable to be used smoothly.

[0007] The utility model solves the above technical problems with the following technical solutions: a glue gun that is convenient for replacing glue, comprising: a glue tank, a glue storage bag and a glue pushing component.

[0008] The glue tank includes a glue cylinder, a top cover and a bottom cover, wherein the top cover is detachably connected to the top opening end of the glue cylinder and a glue outlet hole is provided in the middle thereof; the bottom cover is detachably connected to the bottom opening end of the glue cylinder and a threaded hole is provided in the middle thereof; the glue storage bag is movably placed in the glue cylinder and the bag opening at the top thereof is connected to the glue outlet hole; the glue pushing assembly includes a piston and a screw, wherein the piston slides in the glue cylinder and the top end thereof contacts the bottom end of the glue storage bag; the screw is screwed into the threaded hole and the top end thereof is fixed to the bottom surface of the piston.

[0009] The beneficial effect of the utility model is that the glue storage bag is movably placed in the glue liquid cylinder, which can avoid direct contact between the glue liquid and the inner wall of the glue liquid cylinder, prevent the glue liquid from adhering and solidifying on the inner wall of the glue liquid cylinder, and improve the efficiency of glue liquid replacement.

[0010] On the basis of the above technical solution, the present invention can also be improved as follows.

[0011] Furthermore, the outer peripheral wall of the top end of the glue cylinder is provided with a top external thread; the inner peripheral wall of the top cover is provided with a top internal thread, and the top internal thread is threadedly connected to the top external thread.

[0012] Furthermore, the outer peripheral wall of the bottom end of the glue tank is provided with a bottom external thread; the inner peripheral wall of the bottom cover is provided with a bottom internal thread, and the bottom internal thread is threadedly connected to the bottom external thread.

[0013] Furthermore, it also includes a glue gun nozzle, the bottom end of which is detachably connected to the top end of the top cover and the bottom opening end of which is connected to the glue outlet hole.

[0014] Furthermore, it also includes a handle, which is fixed to the protruding end of the screw that is screwed out of the threaded hole. BRIEF DESCRIPTION OF THE DRAWINGS
