Problems solved by technology

Its disadvantages are: ①When manually pulling the trigger, the hand will work hard and be easily fatigued, and it is not easy to support the stability of the caulking gun
②When manually pulling the trigger, it is easy to cause the gun to kowtow, and the kowtow will cause the extruded glue strip to break or produce a bean-shaped rubber surface, resulting in uneven rubber surface
③Because the trigger is pulled manually, the pressure is small and uneven, and some thin seams cannot squeeze the glue in, and the sealing effect cannot be achieved.
④ Due to the uneven thickness of the rubber strip after manually pulling the trigger, it affects the sealing quality and appearance
⑤ Low work efficiency

Abstract

The invention relates to the waterproof seal or the upholster industry in the building trade, in detail, the invention provides an electric caulking gun, which is used for waterproof seal. The structure includes a casing, the front part inside the casing is connected with a sleeve, a head cover is arranged on the sleeve, a motor is arranged in the casing, the motor is connected with a screw arranged in the center of the casing by a transmission device, the front part of the screw is connected with a combined piston, and the rear part thereof is connected with a hook, the motor is connected with a switch arranged on the casing. Compared with the prior art, the invention is characterized by reasonable design, simple structure, convenient operation, environment protection without pollution, good construction effect and high working efficiency.

Description

technical field [0001] The invention relates to waterproof sealing in construction industry or decoration industry, and specifically provides an electric caulking gun for waterproof sealing. Background technique [0002] The caulking guns under the prior art are all manual mechanical, and its working process is to manually pull the trigger of the caulking gun, and one-way forward movement extrudes the glue strip. Its shortcoming is: 1. when manually pulling the trigger, the work intensity of the hands is big and it is easy to get tired, and it is difficult to hold the stability of the caulking gun. ②When the trigger is manually pulled, it is easy to cause the gun to kowtow, and the kowtow will cause the extruded glue strip to break or produce a bean-shaped rubber surface, resulting in uneven rubber surface. ③Because the trigger is pulled manually, the pressure is small and uneven, and some thin seams cannot squeeze the glue in, and the sealing effect cannot be achieved. ④ ...
