The two ends of the two second elastic sections 216 are fixedly connected with the second connecting sections 217, one of the second connecting sections 217 is fixedly connected to one side of the mounting strip 215, and the thickness of the first elastic section 214 and the second elastic section 216 gradually changes from thin to thick from the middle to both sides; the card strip card slot 17 is connected by an arc circular groove 173, a first square groove 171 and four second square grooves 172, and the positions of the arc circular groove 173, the second square groove 172 and the first square groove 171 correspond to the semicircular body, the second elastic limiting piece and the rectangular parallelepiped respectively.

[0051] When installing the side cover 2, align the T-shaped clip 21 with the arc-shaped circular groove 173 and the first square groove 171 on the clip slot 17 and insert it. The two groups insert the mounting strip 215, the second elastic section 216 and the second connecting section 217 into the second square groove 172 accordingly until the entire T-shaped clip 21 is inserted into the clip slot 17. Since the rack clip 24 will contact the rack cross bar 13 during the insertion process, the entire side cover 2 will be squeezed outward. At this time, the squeezing force of the side cover 2 outward will pull the T-shaped clip 21, and the semicircular body of the T-shaped clip 21 will squeeze the first elastic section 214 in the arc-shaped circular groove 173, so that the first elastic section 214 is compressed and deformed, and the installation is carried out at the same time. The strip 215 will squeeze the second elastic section 216 toward the second square groove 172, causing the second elastic section 216 to be compressed and deformed, and then the entire side cover plate 2 is moved outward under the deformation of the first elastic section 214 and the second elastic section 216, while not affecting the insertion of the T-shaped clip 21 into the clip slot 17, until the frame clip 24 is inserted into the side of the welding frame 1, the side cover plate 2 loses the squeezing force of the frame clip 24, and the first elastic section 214 and the second elastic section 216 recover their deformation. The first elastic section 214 and the second elastic section 216 can increase the buffering property of the side cover plate 2, and when impacted by external force, the side cover plate can be effectively buffered to reduce the degree of damage.

[0053] When installing the top cover 4, the installation slide bar 42 of the top cover 4 is inserted into the slide bar groove 131 on the frame cross bar 13 until the entire installation slide bar 42 enters the interior of the slide bar groove 131. During the insertion process, the semi-cylinder 43 will be adapted and engaged with the semi-circular groove 132 inside the slide bar groove 131, and the triangular block 44 on the installation slide bar 42 will be compressed into the interior of the sliding groove at the edge position of the slide bar groove 131 until the triangular block 44 slides to the position of the triangular groove 133, and the triangular block 44 is inserted into the triangular groove 133, thereby limiting and fixing the entire top cover 4 in the slide bar groove 131 on the frame cross bar 13, and the installation slide bar 42 inside the slide bar groove 131 is inserted into the slide bar groove 212 of the T-shaped card strip 21, limiting and fixing the T-shaped card strip 21.

[0054] like Figures 10 to 12As shown, the cooling assembly 5 includes a cooling tube body 51 fixedly connected to the inner surface wall of the tube hole 25. The cooling tube body 51 compresses and cools the air passing through the outside to the inside of the electric welding machine. A plurality of cooling tube bodies 51 correspond to the positions of a plurality of tube holes 25 one by one. The cooling tube bodies 51 are installed on the tube holes 25 one by one. A tube body connecting strip 53 is fixedly connected between every two adjacent cooling tube bodies 51. A plurality of tube body connecting strips 53 connect the plurality of cooling tube bodies 51 to form a whole. The tube body connecting strip 53 is The length, width and height are consistent with those of the adapting groove 252, and the position of the tube connecting strip 53 corresponds to the adapting groove 252. When the entire cooling tube body 51 and the tube connecting strip 53 are inserted into the tube hole 25, the tube connecting strip 53 is correspondingly inserted into the adapting groove 252, so that the cooling tube body 51 and the tube connecting strip 53 are on the same horizontal plane as the outer surface of the side cover plate 2, and will not affect the fitting of the rotating cover plate 3 and the side cover plate 2; it also includes a fixing structure for fixing the tube hole 25 to the cooling tube body 51, and the cooling tube body 51 is composed of a The air section 513, a diameter reducing section 512 and an air inlet section 511 are connected in sequence. The air outlet section 513 and the air inlet section 511 are both hollow cylindrical structures. The diameter of the air outlet section 513 is larger than the diameter of the air inlet section 511. The diameter reducing section 512 is used to connect the air outlet section 513 and the air inlet section 511. The fixing structure includes a tube body elastic buckle 52 fixedly connected to the outer wall of the air outlet section 513. The inner wall of the tube hole 25 is provided with a tube groove 251. The air outlet section 513 and the tube hole 25 are connected by the tube body elastic buckle 52 and the tube groove. 251 cooperates with the fixed connection. When the electric welder is working, the fan 8 will blow air to the inside of the electric welder, and the blown air will be discharged from the first heat dissipation slot 11, so that a negative pressure will be formed inside the electric welder frame 1, and the external air will be attracted to enter the inside of the electric welder frame 1 from the air outlet section 513 via the reducing section 512 and the air inlet section 511. In the process of air from the air outlet section 513 to the air inlet section 511, the diameter of the cooling tube body 51 becomes smaller. According to the relay effect, the air will be cooled in the cooling tube body 51, thereby assisting in cooling the internal temperature of the electric welder frame 1;The tube body connecting strip 53 is composed of two fixed sections 531, two reset sections 533 and a deformation section 532. The two fixed sections 531 are fixedly connected to the outer wall of the air outlet section 513 in parallel. The reset section 533 is connected to one side of the two fixed sections 531, and the deformation section 532 is connected to the opposite end of the two reset sections 533. The thickness of the fixed sections 531 and the deformation section 532 gradually changes from thin to thick from the middle to the two ends. When installing the cooling tube body 51, the cooling tube body 51 is inserted into the tube hole 25 until the elasticity of the tube body of the surface wall of the cooling tube body 51 is The buckle 52 contacts the tube hole 25 and continuously squeezes the cooling tube body 51. At this time, the reset section 533 contacts one side of the tube hole 25. Under the action of the squeezing force, the reset section 533 bends and deforms. While the reset section 533 bends and deforms, it squeezes the deformation section 532 and compresses and deforms until the entire tube elastic buckle 52 enters the tube groove 251. After entering the tube groove 251, the deformation section 532 and the reset section 533 restore their deformation, thereby limiting and fixing the cooling tube body 51 inside the tube groove 251 on the tube hole 25.

[0055] The working principle provided by the present invention is that during installation, the fan 8 and the fan cover 81 are first installed on the fan port 14, and the heat dissipation base plate 7 is clamped to the bottom of the electric welding frame 1. When the heat dissipation base plate 7 is installed, the L-shaped card 73 on the side close to the fan 8 is inserted into the card slot 15 on the electric welding frame 1, and then the L-shaped card 73 on the other side is pressed downward. Since the heat dissipation base plate 7 is made of copper, it has good heat dissipation ability and ductility, so the heat dissipation base plate 7 will be deformed when pressed until the L-shaped card 73 is inserted into the corresponding card slot 15, thereby limiting and fixing the heat dissipation base plate 7. After the heat dissipation base plate 7 is installed, the electric welding structure 6 is installed on the heat dissipation base plate 7.

[0056] Secondly, the side cover plate 2 is installed on the welding machine frame 1 through the first clamping structure. When installing the side cover plate 2, the T-shaped clip 21 is aligned with the arc-shaped circular groove 173 and the first square groove 171 on the clip slot 17 and inserted. The two groups insert the mounting strip 215, the second elastic section 216 and the second connecting section 217 into the second square groove 172 accordingly until the entire T-shaped clip 21 is inserted into the clip slot 17. Since the frame clip 24 will contact the frame cross bar 13 during the insertion process, the entire side cover plate 2 will be squeezed outward. At this time, the squeezing force of the side cover plate 2 outward will pull the T-shaped clip 21, and the T-shaped clip 21 The semicircular body will squeeze the first elastic section 214 in the arc-shaped circular groove 173, causing the first elastic section 214 to be compressed and deformed. At the same time, the mounting strip 215 will squeeze the second elastic section 216 toward the second square groove 172, causing the second elastic section 216 to be compressed and deformed. Then, the entire side cover 2 moves outward under the deformation of the first elastic section 214 and the second elastic section 216, and at the same time, it does not affect the insertion of the T-shaped clip 21 into the clip slot 17, until the frame clip 24 is inserted into the side of the welding frame 1, the side cover 2 loses the squeezing force of the frame clip 24, and the first elastic section 214 and the second elastic section 216 recover their deformation.

[0057] Then open the rotating cover 3, lift up the rotating cover 3, rotate the support bar 32 at the bottom end of the placement slot 31, and then insert one end of the support bar 32 into the support protrusion 23 on the support slot 22, limit the support bar 32 by the support protrusion 23, and then support the rotating cover 3 through the support bar 32 to support it on the side cover 2.

[0058] The cooling assembly 5 is installed on the side cover plate 2. When installing the cooling tube body 51, the cooling tube body 51 is inserted into the tube hole 25 until the tube body elastic buckle 52 on the surface wall of the cooling tube body 51 contacts the tube hole 25. The cooling tube body 51 is continuously squeezed with force. At this time, the reset section 533 contacts one side of the tube hole 25. Under the action of the squeezing force, the reset section 533 bends and deforms. While the reset section 533 bends and deforms, it squeezes the deformation section 532 for compression deformation until the entire tube body elastic buckle 52 enters the tube groove 251. After entering the tube groove 251, the deformation section 532 and the reset section 533 restore their deformation, thereby limiting and fixing the cooling tube body 51 inside the tube groove 251 on the tube hole 25.

[0059] Finally, the top cover 4 is installed on the two frame cross bars 13 through the second clamping structure. When installing the top cover 4, the installation slide bar 42 of the top cover 4 is inserted into the slide slot 131 on the frame cross bar 13 until the entire installation slide bar 42 enters the interior of the slide slot 131. During the insertion process, the semi-cylinder 43 will be adapted and clamped with the semi-circular groove 132 inside the slide slot 131, and the triangular clamping block 44 on the installation slide bar 42 will be compressed into the interior of the sliding groove at the edge position of the slide slot 131 until the triangular clamping block 44 slides to the position of the triangular groove 133, and the triangular clamping block 44 is clamped into the triangular groove 133, thereby limiting and fixing the entire top cover 4 in the slide slot 131 on the frame cross bar 13, and the installation slide bar 42 inside the slide slot 131 is clamped into the slide slot 212 of the T-shaped clamping bar 21, limiting and fixing the T-shaped clamping bar 21.

[0060] Then the whole welding machine is installed. When the welding machine needs to work, the welding machine is connected, and the rotating cover plate 3 is opened so that the cooling component 5 on the side cover plate 2 is in contact with the outside to assist in cooling the internal welding structure 6.
