Description

Technical Field

[0001] The invention relates to the technical field of metal material welding auxiliary devices, and mainly to a handheld welding gun device for metal material welding. Background Art

[0002] Metal materials refer to materials with properties such as luster, ductility, easy conductivity and heat transfer. They are generally divided into two types: ferrous metals and non-ferrous metals. Ferrous metals include iron, chromium, manganese, etc. Among them, steel is the basic structural material, known as the "skeleton of industry." Due to the advancement of science and technology, the widespread application of various new chemical materials and new non-metallic materials has led to an increasing number of substitutes for steel, and the demand for steel has declined relatively. However, to date, the dominant position of steel in the composition of industrial raw materials is still difficult to replace, and handheld welding guns are often required for welding metal materials;

[0003] The existing patent publication number is CN209532377U, which is a handheld welding gun device for welding metal materials. The distance between the welding gun body and the handle is adjusted by driving the welding gun body up and down through a connecting rod, and the self-locking is completed by the roller being clamped into the gap between the protrusions, so that the use height of the welding gun body can be adjusted according to different types of welding wires, thereby avoiding the burning and spreading of the welding wire to scald the operator and expanding the use range of the welding gun. However, the device makes it difficult for the user's hand to be tightly connected to the welding gun body, and the welding gun body is easily separated from the hand, thereby causing the welding gun body to fall to the ground and be damaged. In addition, when the handle or the welding gun body needs to be repaired and the device needs to be stored, it is difficult to disassemble and separate the handle and the welding gun body, which increases the difficulty of maintenance and is inconvenient for storage. Therefore, it is necessary to design a handheld welding gun device for welding metal materials to solve the above problems. Summary of the invention

[0008] In the present invention, the first worm and the first worm wheel cooperate to form a self-locking structure to prevent the first worm wheel from rotating on its own. The rotation of the pinion gear makes it easier for the two racks to move in opposite directions, thereby facilitating the adjustment of the tightness of the strap and fixing the back of the hand to prevent the device from falling off. When one of the racks moves to one end, the rack squeezes the L-shaped rod to disengage the limit rod from the angle adjustment mechanism, thereby facilitating disassembly.

[0009] Furthermore, a push rod is fixed on one side of the rack away from the strap, and one side of the push rod is provided with a first bevel;

[0010] A second bevel is provided on one side of the top of the L-shaped rod, and the second bevel matches the first bevel.

[0011] In the present invention, the first beveled edge cooperates with the second beveled edge to facilitate the push rod to push the L-shaped rod, thereby facilitating the movement of the L-shaped rod.

[0012] Furthermore, the moving device includes a fixing seat connected to one side of the welding gun body, a screw rod rotatably connected to one side of the fixing seat, and a C-shaped seat penetratingly connected to one side of the screw rod.

[0013] In the present invention, the rotation of the screw rod facilitates the movement of the C-shaped seat, thereby facilitating the adjustment of the position of the handle.

[0014] Furthermore, the angle adjustment mechanism includes a rotating seat rotatably connected to one side of the C-shaped seat, a second worm wheel connected to the bottom of the rotating seat, a second worm screw meshingly connected to one side of the second worm wheel, the second worm screw rotatably connected to the C-shaped seat on both sides, and a knob fixed to one side of the second worm screw.

[0015] In the present invention, the second worm and the second worm wheel cooperate to form a self-locking structure, thereby preventing the second worm wheel from rotating on its own.

[0016] Furthermore, a T-shaped slider is fixed to one side of the rack;

[0017] T-shaped slide grooves are arranged on both sides of the handle, and the groove body of the T-shaped slide groove is slidably connected with the T-shaped sliding block.

[0018] In the present invention, the cooperation between the T-shaped slide groove and the T-shaped slider improves the stability of the rack and prevents the rack from shaking.

[0019] Furthermore, a slot is provided on one side of the handle;

[0020] An insert block is fixed on one side of the rotating seat, and the insert block matches with the slot body of the slot.

[0021] In the present invention, the slot cooperates with the insert block to facilitate positioning of the handle.

[0022] Furthermore, a limiting groove is provided on one side of the insert block, the groove body of the limiting groove cooperates with the limiting rod, and the limiting rod is slidably connected to the groove body of the handle.

[0024] Furthermore, an opening is provided on one side of the handle, and one side of the opening is rotatably connected to a roller, and the roller cooperates with the strap.

[0025] In the present invention, the roller reduces the friction between the handle and the strap, thereby preventing the strap from being worn and broken.

[0026] Furthermore, a rotating rod is fixed on one side of the screw rod, a cross rod is fixed on one side of the rotating rod, and the cross rod and the rotating rod form a T-shaped structure.

[0027] In the present invention, the cross bar and the rotating rod form a T-shaped structure to facilitate the user to rotate the screw rod.

[0028] Furthermore, the outer wall of the turntable is provided with anti-slip grooves, and one side of the turntable is located outside the handle.

[0029] In the present invention, the anti-slip pattern facilitates the user to push the turntable, thereby causing the turntable to rotate.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] The present invention enables the C-shaped seat to move by rotating the screw rod, thereby driving the rotating seat and the handle to move, and realizes the position of the handle to be adjusted. The second worm is rotated by the knob, thereby driving the second worm gear and the rotating seat to rotate, and then driving the handle to rotate, and realizes the angle of the handle to be adjusted. The first worm is rotated by the turntable, thereby driving the first worm gear and the second bevel gear to rotate, and then driving the first bevel gear and the pinion gear to rotate. The rotation of the pinion gear causes the two racks to move in opposite directions, thereby adjusting the tightness of the strap, which is convenient for fixing the back of the hand and preventing the device from falling off. The push rod pushes the L-shaped rod, thereby causing the limit rod to disengage from the limit groove, which is convenient for the handle to be separated from the plug block and realize the removal of the handle. At the same time, the strap can be tightened to prevent the strap from being too long and difficult to be stored. The device can not only adjust the position and angle of the handle, but also the user can adjust it according to his own habits, thereby improving the comfort of the user, and the handle can be disassembled for easy storage, and the tightness of the strap can be adjusted to make the strap fit closely to the hand and prevent the device from falling off.
