Description

Technical Field

[0001] This utility model belongs to the field of electric welding machine technology, and specifically relates to a portable electric welding machine. Background Technology

[0002] An electric welding machine uses the high-temperature electric arc generated when the positive and negative electrodes are momentarily short-circuited to melt the solder on the welding rod and the material being welded, thus bonding the objects together. Its structure is very simple; it's essentially a high-power transformer. Electric welding machines are generally classified into two types based on the type of output power: AC and DC. They utilize the principle of inductance; the inductance generates a huge voltage change when the circuit is switched on and off. The high-voltage arc generated when the positive and negative electrodes are momentarily short-circuited melts the solder on the welding rod, achieving atomic bonding.

[0003] While existing welding machines are equipped with wheels for mobility, their height is low and cannot be adjusted, making them inconvenient to move. Furthermore, welding machines require the use of numerous accessories, but existing welding machines cannot store these accessories, further complicating their operation. Therefore, we propose a portable welding machine. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This portable welding machine features an adjustment structure. Pressing down the protrusion moves the connecting rod via the movable plate, compressing the first spring. The connecting rod then presses against the second pressure plate via the first pressure plate. The fixed rod on the second pressure plate slides within the groove on the surface of the fixed block. The movable pin, in cooperation with the groove, pushes the moving block, causing the locking pin to move out of the circular groove inside the outer casing and retract into the pull rod, releasing the position limit on the pull rod. Pulling the pull rod allows for adjustment of its length. After releasing the protrusion, the first spring pushes the movable plate, preventing the first pressure plate from contacting the second pressure plate. The second spring then pushes the moving block, pushing the locking pin out of the pull rod and locking its position. The length of the pull rod can be adjusted as needed, making adjustment simple and quick. The pull rod can also be used to lift the welding machine at a certain angle, facilitating its movement.

[0014] 2. This portable welding machine is equipped with a protective plate, cabinet door one, cabinet door two, and a storage cabinet. After opening the protective plate, one side of cabinet door one can be inserted into the square groove four on the surface of the protective plate to fix the position of the protective plate and prevent it from falling.

[0030] Working principle: In use, slide open cabinet door 6 and cabinet door 7, place the accessories inside the storage cabinet 9, press down the protrusion 43, and the connecting rod 45 moves through the movable plate 42, compressing the spring 44. The connecting rod 45 presses the pressure plate 47 through the pressure plate 46, and the fixing rod 48 on the pressure plate 47 slides in the groove 1 on the surface of the fixing block 410. Through the cooperation of the movable pin 49 and the groove 2, the moving block 412 is pushed, causing the locking pin 413 to move out of the circular groove 1 inside the outer shell 1 and retract into the pull rod 41, releasing the position limit of the pull rod 41. Pulling the pull rod 41 can adjust the length of the pull rod 41. After releasing the protrusion 43, the spring... Pushing the movable plate 42 with spring 44 causes the pressure plate 46 to no longer contact the pressure plate 47. Spring 411 pushes the moving block 412 to move, pushing the locking pin 413 out from inside the pull rod 41 to lock the position of the pull rod 41. The welding machine is then raised to a certain angle by the pull rod 41, making it easier to move the welding machine. After moving it to a suitable position, the protective plate 5 is opened, and one side of the cabinet door 6 is inserted into the square groove 4 on the surface of the protective plate 5 to fix the position of the protective plate 5 and prevent it from falling. This makes it easier to connect the accessories to the welding machine body 8 for welding operations. The dustproof blocks 2 on both sides increase heat dissipation while reducing the possibility of dust entering the outer shell 1.
