Caulking gun having lightweight intensified structure

Abstract

A caulking gun having a lightweight intensified structure comprises a handle unit and a bracket made of a material different from the body. The handle unit comprises a plastic body, a pushing group and a trigger element pivoted to the body. The pushing group is provided with a push rod that flexibly passes through the body, and a pushing disc disposed at the end part of the pushing rod. The trigger element can push the push rod and drive the pushing disc to be departed from the body. The bracket comprises a fixing part firmly embedded into the body, two connection walls that are formed by parallel extension of the fixing part and exposed outside the body, an end wall in connection with the end part of the connection wall, and a pushing chamber that is bounded by the body, the connection wall and the end wall, and holds the push rod and the push disc, and achieves the effects of lightweight and intensified whole structure.

Description

Technical field [0001] The invention relates to a paste gun, in particular to a paste gun with a lightweight reinforced structure. Background technique [0002] Generally, for the pasting guns disclosed in the US 5,875,920 and US 4,081,112 patents, the body of the gun is made of metal materials to obtain a certain structural strength. Therefore, the body of the gun alone has a certain weight, and then it is fitted with a pusher. After the silicone tank is installed, not only the operation process is more laborious, but also when the operation time is long, it is easy to cause muscle soreness and other injuries due to long-term holding of heavy objects, which is quite unsatisfactory. [0003] Refer to figure 1 versus figure 2 Therefore, there is a lightweight paste gun 1 on the market, which has a plastic gun body 11, a plastic bracket 12 embedded in the front end of the gun body 11, and a plastic bracket 12 installed on the gun body 11 and can be worn The propulsion unit 13 of th...

AI Technical Summary

Problems solved by technology

[0007] Although this paste gun 1 changes the material of the gun body 11 and the bracket 12 into plastic to reduce the overall weight, but only the hook 112 and the slot 121 are used between the gun body 11 and the bracket 12. When the operator pulls the trigger 113 and drives the push plate 132 to squeeze the silicone tank 14, because the silicone tank 14 is limited in the bracket 12, the bracket 12 will also be pushed , when the force applied by the user increases, because the bracket 12 is a relatively thin plastic structure, it will be slightly deformed and separated from the gun body 11. These displacements absorb the thrust, which will cause the actual push plate 132 to squeeze the silicone tank 14. The thrust cannot be effectively improved, and its structural strength needs to be improved
