DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0021] The utility model provides a handheld welding gun structure for ship maintenance. Figures 1-4The utility model provides a handheld welding torch for ship maintenance, which comprises a handle 1, a welding head 2 arranged on the handle 1, and the handle 1 is held by an operator and welding is performed through the welding head 2.

[0022] Considering that the ship is prone to pitching on the water surface, the welding torch may slide and move, and the welding head 2 may be damaged due to collision. In order to protect the welding head 2, a round block 3 is fixedly connected to each side of the handle 1, the round block 3 is located at one end of the handle 1 close to the welding head 2, a square block 4 is rotatably connected to the end of the round block 3 away from the handle 1, a circular groove 5 is formed through the square block 4, a sliding rod 7 is slidably arranged in the circular groove 5, a square groove 9 is formed in one end of the sliding rod 7 close to the welding head 2, a roller 11 is arranged in the square groove 9, the roller 11 has an appropriate outer diameter, a circular rod 10 is fixedly connected to the roller 11, and the circular rod 10 is concentrically arranged with the roller 11. The circular rod 10 is rotatably connected to the sliding rod 7.

[0023] When the two rollers 11 are respectively arranged on the two sides of the welding head 2, the welding head 2 can be protected whether it slides along the axial length direction of the handle 1 or rolls along the radial length direction of the handle 1, so that the welding head 2 is prevented from colliding during the sliding and moving of the welding torch.

[0024] In addition, during the interval of welding operation, for example, when the operator needs to rest, the welding torch can be placed in the manner that one of the rollers 11 is laid on the ship, that is, the two rollers 11 are arranged one above the other to prevent the rollers 11 from rolling randomly.

[0025] In addition, since the ship has a large volume, a long weld seam usually needs to be welded. In order to reduce the working strength of the operator, when a long weld seam is welded, the sliding rod 7 is rotated downward to drive the square block 4 to rotate on the round block 3, so that the two rollers 11 are respectively abutted on the two side positions of the weld seam, and the rollers 11, the sliding rod 7, the square block 4 and the like form a moving support structure to support the handle 1 and the welding head 2, and the moving support structure can move to reduce the working strength of the operator. The square block 4 is rotatably arranged on the round block 3, so that the inclination angle of the sliding rod 7 is adjustable, the sliding rod 7 can slide in the circular groove 5, the support height is adjustable, and the flexibility of use is improved.

[0026] The connecting rod 8 is fixedly connected between the two sliding rods 7, so that the two sliding rods 7 move synchronously, and the stability of the moving support structure is improved.

[0027] Through the arrangement of the sliding rod 7, the roller 11 and the square block 4 and the like, the two rollers 11 are respectively arranged on the two sides of the welding head 2 to protect the welding head 2 from collision during the sliding and moving of the welding torch, and the rollers 11, the sliding rod 7, the square block 4 and the like form a moving support structure to reduce the working strength of the operator.

[0028] In order to reduce the weight of the handheld welding gun, facilitate the operator to hold, the roller 11 is provided with a plurality of weight reduction grooves 12 penetratingly arranged.

[0029] In order to fix the position of the slide rod 7, one of the blocks 4 is provided with a first threaded groove 6 penetratingly arranged on the side opposite to the handle 1, the first threaded groove 6 is communicated with the corresponding circular groove 5, and the first threaded groove 6 is internally threadedly connected with a first bolt 13. When the adjustment of the slide rod 7 in the circular groove 5 is completed, the first bolt 13 is rotated, the end of the first bolt 13 is pressed against the slide rod 7, and the position of the slide rod 7 is fixed.

[0030] In order to fix the inclination angle of the slide rod 7, the other block 4 is provided with a second threaded groove 16 penetratingly arranged, and the second threaded groove 16 is internally threadedly connected with a second bolt 15.
