[0001] The utility model belongs to the technical field of glue guns, and particularly relates to a gas storage type glue gun. Background Art

[0002] A glue gun is a tool for applying glue or extruding glue, which is used to push out the glue in the glue cartridge in sections. The glue gun includes a gun body, an operation handle and a push rod. The gun body is used to place the glue cartridge. The push rod acts on the glue cartridge through a push block at the rod end to squeeze the bottom of the glue cartridge so that the glue in the glue cartridge is extruded from the nozzle of the glue cartridge. The operation handle is used to push the push rod. Existing glue guns are divided into manual glue guns, pneumatic glue guns and electric glue guns. Among them, the pneumatic glue gun uses air pressure as power for applying glue and is a high-efficiency glue application tool, which is widely used in fields such as the construction industry, decoration industry, automobile manufacturing and repair, and glass curtain wall projects.

[0003] With the progress of society, both electric glue guns and pneumatic glue guns have begun to be popularized in the market. However, existing pneumatic glue guns require continuous supply of external air sources during operation. If there is no available external air source at the construction site or the external air source has problems, the pneumatic glue gun will not be able to work properly, which will seriously affect the construction progress.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0022] Referring to Figures 1-4 as shown, the present invention provides a gas storage type glue gun, which includes a glue gun frame 1. A positioning bin 13 is provided on the right end face of the glue gun frame 1 for storing a glue tube. A push rod 11 is slidably connected inside the glue gun frame 1. A pressing piece 12 is fixedly connected to the right end of the push rod 11. The pressing piece 12 is located inside the positioning bin 13. An air tank 3 is fixedly connected to the side wall of the glue gun frame 1. A gas pressing mechanism 5 is provided on the side wall of the air tank 3. The air tank 3 is inflated and stores gas through the gas pressing mechanism 5, effectively avoiding the problem that the pneumatic glue gun cannot work properly when there is a lack of available external gas source or external gas source failure at the construction site.

[0023] In a further embodiment, referring to Figures 1-2 , the gas pressing mechanism 5 includes an annular base 51 and an air bag 52. The annular base 51 is fixedly connected to the side wall of the air tank 3. The air bag 52 is fixedly connected to the right end of the annular base 51. The air bag 52 is fixedly connected to the right end of a moving ring 54. The inner wall of the moving ring 54 is slidably connected to the side wall of the air tube.

[0024] In this embodiment, by holding the moving ring 54 and making it reciprocate along the side wall of the air tank 3, the air bag 52 is activated to enter the working state. In this way, the air tank 3 can be inflated and store gas.

[0025] In a further embodiment, referring to Figure 2 , an intake check valve 53 is provided on the side wall of the air bag 52. The intake check valve 53 ensures that gas can only enter the inside of the air bag 52 from the outside.

[0026] In this embodiment, through the provided intake check valve 53, during the working process of the air bag 52, the outside air can flow into the inside of the air bag 52, while the gas inside the air bag 52 cannot flow to the outside.

[0027] In a further embodiment, referring to Figure 2 , an outlet check valve 31 is fixedly connected between the air bag 52 and the air tank 3. The outlet check valve 31 ensures that the gas in the air bag 52 can only flow into the air tank 3 unidirectionally.

[0028] In this embodiment, through the provided outlet check valve 31, when the air bag 52 is squeezed, the gas inside the air bag 52 is compressed into the air tank 3 through the outlet check valve 31 and stored.

[0029] In a further embodiment, referring to Figure 3 , a handle 4 is fixedly connected to the side wall of the glue gun holder 1 located on the left side of the annular base 51. A control valve 41 is fixedly connected inside the handle 4. A first connecting pipe 42 and a second connecting pipe 44 are fixedly connected to the side wall of the control valve 41. The free end of the first connecting pipe 42 penetrates into the positioning chamber 13, and the second connecting pipe 44 penetrates into the gas tank 3 inside. A control button 43 is arranged on the side wall of the handle 4, and the control button 43 cooperates with the control valve 41.

[0030] In this embodiment, by pressing the control button 43, the control valve 41 is driven to work. At this time, the invention inside the control valve 41 is opened. Since the air pressure inside the gas tank 3 is greater than the air pressure inside the positioning chamber 13, the gas inside the air pipe sequentially passes through the second connecting pipe 44, the control valve 41, and the first connecting pipe 42 to reach the inside of the positioning chamber 13. At this time, the increased air pressure inside the positioning chamber 13 on the left side of the pressing piece 12 will push the pressing piece 12 to move, thereby achieving the effect of extruding the glue inside the rubber tube.

[0031] In a further embodiment, referring to Figures 3-4 , a sealing fixed cover 2 is threadedly connected to the right end of the glue gun holder 1, and the sealing fixed cover 2 is used to fix the rubber tube.

[0032] In this embodiment, by the threaded connection between the sealing fixed cover 2 and the glue gun holder 1, on the one hand, it can play a role in fixing the rubber tube, and on the other hand, by the close contact between the right end face of the rubber tube and the inner wall of the sealing fixed cover 2, the effect of sealing the positioning chamber 13 is achieved.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
