DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figures 1 to 4 As shown, a welding power source provided by an embodiment of the utility model comprises: a body 1, a contact base 2 is arranged on the lower surface of the body 1, and a plurality of connectors 3 are arranged at one end of the body 1; a sealing assembly 4 and a lifting assembly 5, wherein the sealing assembly 4 is provided with a plurality of groups, and the plurality of sealing assemblies 4 are respectively fixedly mounted on the outer surfaces of the plurality of connectors 3, and the lifting assembly 5 is fixedly mounted on the lower surface of the sealing assembly 4;

[0026] When using a welding power source, it needs to be used in conjunction with a welding head. The existing connection between the welding power source and the welding head does not have a sealing structure. When connected and used, the user pulls the welding head hard, causing the welding head connection line to fall off and poor contact. At the same time, water stains may fall onto the connection between the welding power source and the welding head, causing moisture and a short circuit, which is dangerous.

[0027] Specifically, Figure 1 As shown, when in use, the connecting wire of the welding head is first passed through the sealing component 4 and connected to the connecting head 3. The sealing component 4 is located on the outer surface of the connecting head 3, so as to prevent water stains from falling into the connecting head 3. After the connection, the sealing component 4 can be pulled to extend the sealing component 4, thereby increasing the protection area, increasing the waterproof effect, reducing the possibility of moisture at the location of the connecting head 3, and improving safety.

[0028] It is worth noting that, when in use, the sealing component 4 can limit the position of the welding head connection line, thereby effectively solving the problem of the welding head connection line falling off and poor contact caused by the user pulling the welding head with force, thereby improving practicality.

[0029] Furthermore, the sealing assembly 4 includes a waterproof cover 401, which is sleeved on the outer surface of the connector 3, and has multiple groups of guide grooves 404 on the outer surface of the waterproof cover 401;

[0030] Specifically, Figure 2 and Figure 3 As shown, the waterproof cover 401 is made of waterproof material and has waterproof properties. In combination with multiple groups of guide grooves 404 opened on the surface, when water stains fall on the surface of the waterproof cover 401, the water stains will flow downward along the guide grooves 404, effectively preventing the water stains from adhering to the waterproof cover 401 for a long time.

[0031] Furthermore, the waterproof cover 401 is provided with an inner lining 402, and both sides of the inner wall of the waterproof cover 401 are provided with slide grooves 403, and both sides of the inner lining 402 are fixedly installed with docking strips 406, and the docking strips 406 are slidably installed in the slide grooves 403;

[0032] Specifically, Figures 2 to 4 As shown, the lining 402 slides in the waterproof cover 401 by sliding the docking strip 406 in the slide groove 403. When in use, the lining 402 is pulled to expand the waterproof area, thereby improving the waterproof effect.

[0033] Furthermore, the lining 402 includes a cylinder 4021, one end of which is fixedly mounted with a limited sealing sleeve 4022, the limited sealing sleeve 4022 is located at one end of the waterproof sleeve 401, and the other end of the cylinder 4021 is detachably mounted with a limited component 405;

[0034] Specifically, Figures 2 to 4 As shown, the lining 402 slides in the waterproof sleeve 401, and a gap is inevitable between the two. However, when the cylinder 4021 slides, the limiting sealing sleeve 4022 follows the sliding and fills the gap between one end of the two, thereby preventing water stains from flowing into the waterproof sleeve 401 along the gap. The limiting component 405 at the other end of the cylinder 4021 can be adjusted according to the thickness of the welding head connecting line, so as to limit and fix the welding head connecting line.

[0035] Furthermore, the limiting component 405 includes a fixing sleeve 4051, and a plurality of limiting sleeves 4053 are detachably installed inside the fixing sleeve 4051. The limiting sleeves 4053 are all provided with through holes in the middle. The outer surface of the fixing sleeve 4051 is provided with a thread strip 4052, and one end of the cylinder 4021 is provided with an internal thread 4023, and the internal thread 4023 is threadedly connected with the thread strip 4052.

[0036] Specifically, Figure 4 As shown, when inserting the welding head connecting wire, first try to pass it through the innermost circle of the limiting sleeve 4053. If it cannot be inserted, the innermost circle of the limiting sleeve 4053 can be removed and the next attempt can be made until the welding head connecting wire is inserted into the limiting sleeve 4053 with the same diameter as the welding head connecting wire. This installation method can maximize the filling of the opening at one end of the cylinder 4021 to avoid the effect of water stains flowing into the waterproof sleeve 401 through the opening at one end of the cylinder 4021.

[0037] Furthermore, the lifting assembly 5 includes a fixing rod 501 and a supporting rod 502. The fixing rod 501 is fixedly installed at the lower end of the waterproof cover 401, and a mounting plate 503 is fixedly installed on one side of the fixing rod 501; the supporting rod 502 is slidably installed in the fixing rod 501, and a plurality of mounting holes 505 are provided on one side of the fixing rod 501 and the supporting rod 502, and fixing bolts 504 are threadedly connected inside the mounting holes 505;

[0038] Specifically, Figures 1 to 3 As shown, during use, the support rod 502 can be pulled downward according to needs. After adjustment, the fixing bolt 504 is inserted into the overlapping mounting hole 505 of the fixing rod 501 and the support rod 502 to fix them, so as to keep the connector 3 away from the ground and avoid the situation where the ground moisture poses a threat to the connector 3.

[0039] The above embodiments are only used to help understand the method and core idea of ​​the utility model. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made to the utility model without departing from the principle of the utility model, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
