Technical Field

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

[0002] With the continuous improvement of living standards and aesthetic awareness, 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 in interior decoration.

[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 labor-saving glue gun that is convenient for replacing glue, comprising: a glue tank, a glue bag, a glue application component and a glue discharging component.

[0008] The top of the glue liquid tank is provided with a glue outlet hole and a limiting cylinder is clamped in the glue outlet hole, an annular limiting portion is fixed on the inner side wall of the limiting cylinder, and a glue pushing hole is provided at the bottom end of the glue liquid tank; the glue liquid bag is movably placed in the glue liquid tank and the bag opening at the top end is connected with the glue outlet hole; the glue applying assembly comprises a piston and a push rod, the piston slides in the glue liquid tank and its top end can contact the bottom end of the glue liquid bag; the top end of the push rod movably passes through the glue pushing hole and is fixed on the bottom surface of the piston; the glue outlet assembly comprises a spring and a glue outlet tube, the spring is coaxially placed in the limiting cylinder and its bottom end is in conflict with the annular limiting portion; the bottom end of the glue outlet tube is a closed end and its closed end is pressed against the top end of the spring, the side wall of the glue outlet tube is provided with a glue through hole and the glue through hole can extend into the glue liquid tank as the glue outlet tube is pressed and compressed.

[0009] The beneficial effects of the utility model are as follows: changing the glue storage method of the traditional glue gun, placing the glue bag containing the glue in the glue tank movably, which can avoid direct contact between the glue and the inner wall of the glue cylinder, prevent the glue from adhering and solidifying on the inner wall of the glue cylinder, and improve the efficiency of glue replacement.

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

[0011] Furthermore, 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; the glue outlet hole is arranged on the top cover; the bottom cover is detachably connected to the bottom opening end of the glue cylinder; the glue pushing hole is arranged on the bottom cover; and the glue bag is movably placed in the glue cylinder.

[0012] Furthermore, it also includes a glue nozzle, which includes a fixing ring, a pressing cover, a glue outlet cone tube and a pressing frame plate, the fixing ring is fixed on the top end of the top cover and a vertical plate is fixed along one side of the fixing ring; the pressing cover is located on the inner side of the fixing ring and a connecting hole is provided in the middle thereof; the top end of the glue outlet tube is inserted into the connecting hole; the glue outlet cone tube is located above the pressing cover and its large end is fixed and connected to the connecting hole; the pressing frame plate is sleeved on the outer peripheral side of the glue outlet cone tube and one end of the pressing frame plate is hinged on the top end of the vertical plate, a pressing block is fixed on the pressing frame plate corresponding to the pressing cover and the pressing block can press the pressing cover as the pressing frame plate rotates.

[0013] A further beneficial effect of adopting the above method is: utilizing the lever principle, the pressing frame plate is sleeved on the outer peripheral side of the discharge cone tube and one end of the pressing frame plate is hinged on the vertical plate. Since a pressing block is fixed above the pressing cover corresponding to the pressing frame plate, when the other end of the pressing frame plate is pressed, the pressing force of the glue gun can be reduced, thereby reducing the labor intensity of the operator and improving the convenience and safety of using the glue gun.

[0014] Furthermore, the annular limiting portion includes a guide ring and a cross limiting plate, the guide ring is fixed on the inner wall of the limiting cylinder; the cross limiting plate is fixed on the inner wall of the guide ring; the spring is placed in the guide ring and its bottom end is in contact with the cross limiting plate.

[0015] The further beneficial effect of adopting the above method is: using the cross limit plate fixed on the inner wall of the guide ring can not only prevent the spring from falling, but also guide the barrel glue tank and the glue outlet hose. BRIEF DESCRIPTION OF THE DRAWINGS
