[0027] Below, the present invention is further described with reference to the accompanying drawings and specific embodiments:

[0028] like Figure 1-3 As shown, a transformer for AC and DC argon arc welding machines that is easy to assemble and disassemble includes a transformer body 2 disposed at the bottom inner side of a housing 1. The housing 1 is provided with an opening 11 on one side of the transformer body 2. A blocking plate 3 is provided on the opening 11. One side of the blocking plate 3 is rotatably connected to the housing 1 via a hinge, and the other side is provided with a locking member 4 connected to the housing 1.

[0029] A transfer assembly 5 is provided between the transformer body 2 and the housing 1 , and is used to drive the transformer body 2 to move to the outside of the housing 1 when the blocking plate 3 is opened;

[0030] It also includes a buffer component 6 arranged between the transformer body 2 and the transfer component 5.

[0031] In this embodiment, when the transformer body 2 needs to be replaced or overhauled, the blocking plate 3 is first opened by the locking member 4, and then the transfer assembly 5 automatically drives the transformer body 2 through the opening 11 to the outside of the housing 1, thereby achieving replacement and overhaul in a larger space without disassembling the housing 1, which is convenient, fast and efficient.

[0032] In addition, in this embodiment, the buffer assembly 6 is provided to avoid resonance between the transformer body 2 and the housing 1 , thereby improving the shock absorption and protection effect of the transformer body 2 .

[0033] In this embodiment, the blocking plate 3 can not only be used to block the opening 11 , but also ensures stable installation of the transformer body 2 inside the housing 1 after being combined with the first elastic member 7 .

[0034] In this embodiment, the locking member 4 is a locking bolt, and the locking member 4 is threadedly connected to the housing 1 .

[0035] Further, such as Figure 1 、 2 As shown in Figure 3, the transfer assembly 5 includes a sliding seat 51 and a transfer plate 52. One end of the transfer plate 52 is close to the opening 11, and the other end is slidably connected to the sliding seat 51. The transformer body 2 is connected to the upper surface of the transfer plate 52 through the buffer assembly 6. A first elastic member 7 is provided between the end of the sliding seat 51 away from the opening 11 and the transfer plate 52. When the transformer body 2 is located inside the housing 1, the first elastic member 7 has elastic potential energy.

[0036] In this embodiment, when the blocking plate 3 is opened, the transfer plate 52 moves relative to the sliding seat 51 in a direction close to the opening 11 under the action of the first elastic member 7, thereby automatically driving the transformer body 2 to the outside of the housing 1; when resetting, after the external force pushes the transfer plate 52 and the transformer body 2 to the inside of the housing 1, the blocking plate 3 is closed and locked by the locking member 4.

[0037] The above structure not only enables the transformer body 2 to automatically extend, but also ensures the installation stability of the transformer body 2 inside the housing 1 .

[0038] Further, such as Figure 1 、 2 3, in order to realize the sliding connection between the sliding seat 51 and the transfer plate 52; a groove 511 is provided on the sliding seat 51 at the sliding connection with the transfer plate 52, and the transfer assembly 5 also includes a guide rod 53 arranged in the groove 511, and the end of the transfer plate 52 away from the opening 11 is slidably connected to the guide rod 53, and the first elastic member 7 is sleeved on the guide rod 53, one end of the first elastic member 7 is connected to the transfer plate 52, and the other end is connected to the sliding seat 51.

[0039] Further, such as Figure 1 、 2 As shown in Figure 3, in order to improve the smoothness of the sliding of the transfer plate 52 relative to the sliding seat 51 and the connection reliability, two or more guide rods 53 are provided, and the first elastic member 7 is provided in a one-to-one correspondence with the guide rods 53.

[0040] Further, such as Figure 1 、 2 As shown in Figure 3, in order to improve the supporting stability of the transfer plate 52 on the transformer body 2 when it is in a non-sliding state, a protrusion 512 is provided on the upper surface of one end of the sliding seat 51 close to the opening 11, and a sliding groove 521 is provided on the lower surface of the transfer plate 52, and the protrusion 512 slides in conjunction with the sliding groove 521.

[0041] Further, such as Figure 1 、 2 As shown in Figure 3, in order to make the transfer plate 52 and the transformer body 2 move slowly and automatically when the blocking plate 3 is opened to prevent them from being damaged by popping out instantly; a first damper 8 is provided between the two first elastic members 7, and the bottom end of the first damper 8 is connected to the sliding seat 51, and the driving end is connected to the transfer plate 52.

[0042] Furthermore, it is characterized in that the first elastic member 7 is a spring or rubber or a combination thereof.

[0043] Further, such as Figure 1 、 2 As shown in Figure 3, four buffer components 6 are distributed below the transformer body 2. The buffer component 6 includes a second damper 61. The bottom end of the second damper 61 is connected to the transfer plate 52, and the driving end is connected to the transformer body 2. The outer side of the second damper 61 is provided with a second elastic member 62, and the two ends of the second elastic member 62 are respectively connected to the transformer body 2 and the transfer plate 52.

[0044] In this embodiment, when the transformer body 2 vibrates, the second elastic member 62 is squeezed to cause it to deform. The reaction force generated by the deformation of the second elastic member 62 can greatly offset the vibration, and the shock-absorbing effect of the second damper 61 is utilized to gradually reduce the vibration of the transformer body 2 to restore it to a normal state; thereby, the transformer body 2 has a good protective effect.

[0045] In addition, in this embodiment, the second elastic member 62 is a spring or rubber or a combination thereof.

[0046] Further, such as Figure 3As shown, in order to improve the dustproof effect of the transformer body 2 and ensure the operational stability, a dust cover 9 is also included to cover the transformer body 2, and a connecting plate 10 is provided between the buffer assembly 6 and the transformer body 2, and the mouth of the dust cover 9 is detachably connected to the connecting plate 10.

[0047] For those skilled in the art, various other corresponding changes and deformations can be made based on the technical solutions and concepts described above, and all of these changes and deformations should fall within the scope of protection of the claims of this utility model patent.
