Description

Technical Field

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

[0002] An electric welding machine uses a high-temperature electric arc generated by a low-voltage, high-current output from two poles to melt the welding rod and the material being welded, thus joining the objects together. It is essentially a high-power transformer. Electric welding machines are generally classified into two types based on the type of output power: AC welding machines and DC welding machines.

[0003] To prevent direct contact with the ground and ensure stability, existing welding machines are usually equipped with foot pads or similar devices on their bottoms. However, welding machines are typically lifted by the handle, which requires a certain level of strength from the user. Therefore, to facilitate handling, rollers are added to the bottom of the welding machine. However, the addition of rollers can reduce the friction between the welding machine and the ground, causing the welding machine to slip on sloping surfaces. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in the prior art by providing a welding machine that can provide sufficient friction to prevent tilting and slippage.

[0005] This utility model can be achieved through the following technical solution: a portable welding machine, including a main body, a mounting column provided on the lower end face of the main body, a mounting groove provided at the bottom of the mounting column, a roller installed in the mounting groove, a pull rod installed on the top of the main body, a sliding plate installed outside the mounting column, a foot pad installed at the bottom of the sliding plate, and an anti-slip texture provided at the bottom of the foot pad.

[0007] In the aforementioned portable welding machine, a groove is provided on the through hole, and a nut is installed on the bolt.

[0008] In the aforementioned portable welding machine, the sliding plate has grooves on both sides, and the foot pad has a mounting block above it.

[0009] In the aforementioned portable welding machine, a locking block is installed inside the mounting block, a spring is installed between the locking block and the mounting block, a limiting part is provided on the sliding plate, and a locking groove is formed on the limiting part.

[0010] In the aforementioned portable welding machine, the main body is provided with a rotating frame and a fixed frame, and the pull rod is provided with an annular groove.

[0011] Compared with the prior art, the advantages of this utility model are: the sliding plate can be used to switch between the foot pad and the roller, which is convenient for moving the welding machine, and the foot pad can be placed down when the welding machine is working to facilitate the stable placement of the welding machine; the combination of bolts and nuts facilitates the stable connection between the sliding plate and the mounting column, and at the same time facilitates the sliding plate to slide on the mounting column.

Detailed Implementation

[0013] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0014] like Figures 1 to 5 As shown, the present invention can be realized through the following embodiments: a portable welding machine includes a main body 1, a mounting post 11 is provided on the lower end face of the main body 1, a mounting groove 12 is provided at the bottom of the mounting post 11, a roller 13 is installed in the mounting groove 12, a pull rod 14 is installed on the top of the main body 1, a sliding plate 2 is installed outside the mounting post 11, a foot pad 3 is installed at the bottom of the sliding plate 2, and an anti-slip texture 31 is provided at the bottom of the foot pad 3.

[0015] The pull rod 14 is used to cooperate with the roller 13 to facilitate the user's movement of the welding machine; a foot pad 3 is installed under the sliding plate 2 so that when the sliding plate 2 is moved, the foot pad 3 moves with the sliding plate 2. When moving, the foot pad 3 moves away from the ground, so that the lower end of the foot pad 3 is higher than the roller 13, thus making the roller 13 contact the ground; when working, the roller 13 is slid down, so that the foot pad 3 contacts the ground. Since the relative height of the foot pad 3 is lower than that of the roller 13 at this time, the roller 13 is lifted up by the foot pad 3 and lifted off the ground, ensuring the stability of the welding machine when working.

[0016] like Figure 1 , Figure 2 and Figure 4 As shown, the sliding plate 2 is provided with a fixing part 21, which has a through hole 211 and a through hole 111 on the mounting post 11. Bolts 4 pass through the through holes 211 and 111. The fixing part 21 is used to guide the sliding plate 2 to slide on the mounting post 11. The bolts 4 fix the sliding plate 2 and the mounting post 11 by passing through the through holes 211 and 111, ensuring that the sliding plate 2 is firmly connected. At the same time, the detachable design of the bolts 4 allows the sliding plate 2 to slide on the mounting post 11.

[0017] like Figure 1 , Figure 2 and Figure 4 As shown, a groove 212 is provided on the through hole 211, and a nut 41 is installed on the bolt 4. The nut 41 and the bolt 4 cooperate to prevent the bolt 4 from loosening and disengaging from the through hole 211 and the through hole 111; the nut 41 cooperates with the groove 212 to increase the contact surface between the bolt 4 and the sliding plate 2 at the end, thereby improving the stability of the connection.

[0018] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, sliding grooves 22 are provided on both sides of the sliding plate 2, and mounting blocks 32 are provided above the foot pads 3. The sliding grooves 22 are used to slide the foot pads 3 on the side of the sliding plate 2, which facilitates the installation and replacement of the foot pads 3; the mounting blocks 32 are used to guide the installation of the foot pads 3 in conjunction with the sliding grooves 22.

[0019] like Figure 5 As shown, a locking block 5 is installed inside the mounting block 32, and a spring 51 is installed between the locking block 5 and the mounting block 32. A limiting part 23 is provided on the sliding plate 2, and a slot 231 is formed on the limiting part 23. The locking block 5 is used to cooperate with the slot 231 to fix the foot pad 3 to the sliding plate 2; the spring 51 keeps the locking block 5 continuously locked in the slot 231 to prevent the locking block 5 from disengaging from the slot 231. At the same time, when the spring 51 is compressed, the locking block 5 can disengage from the slot 231, realizing the design of quick replacement of the foot pad 3.

[0020] like Figure 1 and Figure 2 As shown, the main body 1 is provided with a rotating frame 15 and a fixed frame 16, and the pull rod 14 is provided with an annular groove 141. The rotating frame 15 allows the pull rod 14 to be rotatably connected to the main body 1, making it convenient for the user to pull the pull rod 14 to carry the welding machine; the fixed frame 16 is used to cooperate with the annular groove 141 on the pull rod 14, so that the pull rod 14 is fixed on the main body 1, preventing the pull rod 14 from being placed randomly and affecting the welding work.

[0021] The working principle of this utility model is as follows: When placing the welding machine, the bolt 4 and nut 41 are tightened, thereby sliding the sliding plate 2 so that the foot pad 3 contacts the ground, raising the roller 13 away from the ground, and then the bolt 4 and nut 41 are reset so that the sliding plate 2 and the mounting column 11 are fixed together again.

[0022] When replacing the worn-out foot pad 3, slide the locking block 5 and compress the spring 51. While pressing the locking block 5, slide the mounting block 32 to disengage from the slide groove 22, remove the foot pad 3 from the sliding plate 2, and then replace it with a new foot pad 3.

[0023] When it is necessary to move the welding machine, move the sliding plate 2 upward so that the roller 13 contacts the ground again, take the pull rod 14 from the fixed frame 16, and pull the main body 1 to move through the pull rod 14.

[0024] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
