Description

Glue gun

The present invention relates to a glue injection device, and more particularly to a glue gun.

Tannin is an adhesive with good sealing effect. In the design, decoration or repairing construction, most of the rubber is used for edge sealing, repairing gaps, fixing glass, plate and so on. Therefore, the use of silicone is quite common. Most of the construction of silicone rubber is carried out by means of a glue injection device, such as a glue gun. As shown in Figure 1, the new patent case of the Republic of China Announcement No. M277528 "Glue Gun Extrusion Control Structure" is an example.

Referring to Figures 1 and 2, the extrusion control structure 1 disclosed in the present invention comprises two tube walls 12 fixed at one end of the gun body 11 for containing different glues 13, and two spacers disposed in the tube walls 12 for use in Pushing the push rod 14 of the glue 13 , a hose 15 connected to the tube wall 12 and having a straight strip shape, a grip 16 extending downward from the gun body 11 , and a fixing to the gun The body 11 is adjacent to the wrench 17 of the grip 16, and the hose 15 has a glue outlet 151. By holding the grip 16 by the hand and pulling the wrench 17, the push rod 14 can be advanced to squeeze the glue 13 in the tube wall 12, so that the glue 13 faces the The hose 15 moves in the direction and is output by the glue outlet 151.

However, since the hose 14 has a straight strip shape, in actual use, if the position to be adhered is a corner slit or an eave slit, the straight strip 14 cannot directly penetrate the corner or the slit. Must be operated by the operator The rotation of the body posture and the direction of the wrist can be used for construction filling, thus causing inconvenience in work.

Therefore, the object of the present invention is to provide a glue gun which can be used for a gap of a corner or an eaves and which can improve the construction convenience when filling and joining.

Therefore, the new glue gun includes a gun body, a grip portion extending downward from the gun body, a trigger member pivotably disposed on the gun body and adjacent to the grip portion, and a combination The pressing unit of the gun body, a glue contained in the pressing unit, and a hollow rubber discharging tube.

The rubber hose includes a tubular body portion detachably coupled to the pressing unit and having a first central axis, and an extending portion connected to an end of the tubular body portion opposite to the pressing unit, The extending portion extends away from the pressing unit and away from the first central axis, and the end of the extending portion has an opening for the glue output, by pulling the trigger member The glue in the extrusion unit is output from the discharge tube.

The utility model has the advantages that the extending portion of the rubber hose extends and converges away from the first central axis, so that the protruding portion of the rubber hose can be easily penetrated into the corner gap, thereby improving Convenience of construction work or joint objects.

The foregoing and other technical aspects, features and advantages of the present invention will be apparent from the following description of the preferred embodiments.

Referring to Figures 3 and 4, a preferred embodiment of the present type of glue gun 2 includes a gun body 3, a grip portion 4 extending downwardly from the gun body 3, a metal-made and pivotable pivot a squeezing member 5 disposed on the gun body 3 adjacent to the grip portion 4, a pressing unit 6 coupled to the gun body 3, and two glues 7 accommodated in the squeezing unit 6 are hollow And is detachably connected to the rubber discharge pipe 8 of the pressing unit 6, and a spiral member 9.

The pressing unit 6 includes two adjacent rubber cylinders 61 for holding different glues 7, a pushing member 62 coupled by the pulling member 5, and two seals disposed at one end of the pushing member 62. Plug 63. The pushing member 62 has a connecting portion 621 coupled to the gun body 3, and two push rods 622 extending through the rubber tubes 61, and the plug members 63 are located on the push rods. The end of the 622 can be pushed by the push rod 622 to push the corresponding glue 7, and the plug 63 is in close contact with the inner wall of the rubber tube 61 to facilitate the glue 7 Pushing, and one end of the rubber cartridge 61 is in communication with the rubber hose 8. It should be particularly noted that generally only one rubber cartridge 61 can be used to hold a glue 7. In the preferred embodiment, in order to increase the adhesion effect on the construction, two different glues 7 are used. The compounding is therefore carried out using the second rubber cylinder 61 to hold different glues 7 respectively.

The hose 8 includes a tubular portion 81 detachably coupled to one end of the rubber cylinder 61, and an extending portion 82 opposite to the tubular portion 81 at one end of the rubber cylinder 61. The body portion 81 has a first central axis L ₁ , and the extending portion 82 has a first segment 821 connected to the tubular portion 81 and curved, and a first segment 821 is connected thereto. And having a second section 822 of the second central axis L ₂ , the first central axis L ₁ and the second central axis L ₂ define an angle θ, and the diameter of the extending portion 82 faces away from the The direction of the tubular portion 81 is gradually reduced to form a bundle. In addition, the end of the second segment 822 has an opening 821 for outputting the glue 7, and the angle θ is between 10 and 60 degrees. In the preferred embodiment, the angle is The θ is 45 degrees to illustrate. It should be particularly noted that the second section 822 of the insertion portion 82 of the rubber hose 8 may be in the form of a closed conical shape, and the second section 822 may be cut into a need to visualize the amount of extrusion. Openings 823 of different sizes and calibers allow the mixed glue 7 to flow out quantitatively.

The screw 9 is disposed in the rubber tube 8 , and the glues 7 contained in the rubber tubes 61 are respectively pushed by the push rods 622 into the rubber tube 8 , and the glue 7 After flowing through the spiral member 9, the glue 7 is uniformly stirred and mixed, and then output through the opening 823 of the second portion 822 of the extending portion 82, thereby achieving the adhesive quality requirement.

Referring to Figures 3, 5, and 6, in actual operation, the person points the rubber hose 8 to the position to be adhered, and the hand is gripped by the hand and the trigger member 5 is pulled to interlock the push. The push rods 622 of the member 62 are advanced, and the glues 7 in the rubber tubes 61 are respectively pushed by the plugs 63 disposed at one end of the push rods 622 to make the glues 7 enters the rubber hose 8 and is sufficiently stirred and mixed by the screw member 9, and then output through the opening 823 of the second portion 822 of the extending portion 82. It is more worth mentioning that the first central axis L _{1 of} the tubular body 81 and the second segment 822 of the extending portion 82 are difficult to operate even if the position to be bonded is a corner or a generally small gap. The design of the two central axes L ₂ has an angle θ, so that the rubber tube 8 can easily penetrate the corners or small gaps, so that the person can easily complete the glueing action without adjusting the posture of the body or the wrist.

In summary, the present type of glue gun 2 has an angle θ between the first central axis L _{1 of} the tubular body portion 81 and the second central axis L ₂ of the second portion 822 of the extending portion 82. The extending portion 82 of the rubber tube 8 can penetrate and extend in the corner of the wall to perform adhesive action, and the person does not suffer from back pain caused by adjusting the posture of the body or the wrist, thereby not only improving the convenience during operation, but also avoiding leakage of rain. And to achieve the effect of leakage prevention and rust prevention, it is indeed possible to achieve the purpose of the present invention.

However, the above description is only a preferred embodiment of the present invention, and the scope of the present invention cannot be limited thereto, that is, the simple equivalent change and modification made by the novel patent application scope and the novel description content, All remain within the scope of this new patent.
