The terms "a," "an," "the," "said," and "at least one" are used to indicate the presence of one or more elements/components/parts/etc.; the terms "comprising," "having," and "providing" are intended to be inclusive and mean that there may be additional elements/components/etc. other than the listed elements/components/etc.

As shown in FIG. 1, one embodiment of the present invention discloses a door panel assembly for a welder. The door panel assembly includes a door panel body 101, a latch 102, and an elastic restoring member 103.

The door body 101 is formed with at least one through hole 104 penetrating in a thickness direction of the door body 101. The edge of the through hole 104 is protruded toward one side to form a boss portion 105. The lock 102 abuts on the boss portion 105. And a part of the latch 102 is embedded in the through hole 104. The projection of the upper end surface of the lock catch 102 based on the first plane covers the projection of the through hole 104 based on the first plane. Thus, water dropping from the locking buckle 102 drops to the periphery of the boss part 105 of the door panel body and is blocked by the boss part 105, and the water is prevented from flowing into the interior of the welding machine from the through hole 104.

The lock 102 moves relative to the door main body 101 to adjust the opening and closing of the door assembly. The first plane is a plane where the first side surface of the door panel body 101 is located, that is, a plane where the outer surface of the door panel body 101 is located, and the first side of the door panel body 101 is a side of the door panel body 101 departing from the inside of the welding machine.

Only one through hole 104 is shown in fig. 1 of the present application, but the present application is not limited thereto. The above-described boss portion 105 may be stepped in multiple stages.

As shown in fig. 2, the latch 102 includes a first body portion 106, an intermediate portion 107 and a second body portion 108, and the intermediate portion 107 connects the first body portion 106 and the second body portion 108, respectively. The intermediate portion 107 is located between the first body portion 106 and the second body portion 108, the intermediate portion 107 and the second body portion 108 extend into the interior of the welding machine through the through hole 104, and the first body portion 106 abuts against the boss portion 105.

The second main body 108 includes a first extending portion 109 and a second extending portion 110, the first extending portion 109 and/or the second extending portion 110 is abutted against a second side surface of the door panel body 101, and the second side of the door panel body 101 is opposite to the first side. That is, the second side of the door panel body 101 is the side of the door panel body 101 facing the inside of the welder. During assembly, the first extension 109 or the second extension 110 may be inserted into the through hole 104 of the door panel body 101, and then the other of the first extension 109 and the second extension 110 may be inserted. For example, in the present embodiment, the first extension portion 109 may first extend into the through hole 104, and then the second extension portion 110 may extend into the through hole 104.

The width of the intermediate portion 107 on the side adjacent to the second body portion 108 is larger than the width on the side adjacent to the first body portion 106. Therefore, after the first extension part 109 extends into the through hole 104, the second extension part 110 can smoothly extend into the through hole, the assembly of the door panel assembly is facilitated, and the assembly efficiency is improved.

In this embodiment, the second extending portion 110 is shaped like a slope; as the distance between the second extending portion 110 and the first body portion 106 decreases, the distance between the second extending portion 110 and the intermediate portion 107 increases. This facilitates the smooth insertion of the second extension 110 after the first extension 109 is inserted into the through hole 104, thereby facilitating the assembly of the door panel assembly. The shape of the first extension 109 is not limited in this embodiment. May be in the form of a broken line.

In this embodiment, the outer edge of the first main body 106 is turned downward toward the door panel body 101 to form a flange 111. When the latch 102 moves relative to the door panel body 101, the flange 111 engages with the boss portion 105 to limit the latch 102. That is, when the lock 102 moves, a part of the flange 111 abuts against the boss portion 105, so as to limit the lock 102.

In this embodiment, two ends of the elastic restoring member 103 are respectively connected to the door main body 101 and the latch 102. That is, the door panel body 101 and the latch 102 are connected by the elastic restoring member 103. The latch 102 is moved between the first position and the second position based on the deformation by the elastic restoring member 103. When the latch 102 is in the first position, the door panel assembly is closed. When the latch 102 is in the second position, the door panel assembly is opened.

A recessed portion 112 is formed on an end surface of the latch 102 facing away from the door main body 101, and the recessed portion 112 extends from the first main body 106 to the middle portion 107. The depression 112 facilitates insertion of a user's finger to facilitate movement of the latch 102.

In another embodiment of the present application, the second extending portion 110 is an elastic member. This facilitates the smooth insertion of the second extension 110 after the first extension 109 is inserted into the through hole 104, thereby facilitating the assembly of the door panel assembly.

The embodiment of the utility model also provides a welding machine which comprises a shell, wherein the shell comprises the door panel assembly disclosed by any one of the embodiments. The detailed structural features and advantages of the door panel assembly can be found in the description of the above embodiments and will not be described herein. In this embodiment, the recessed portion on the lock catch is disposed on an end surface of the lock catch facing the outer side of the welding machine housing. The edge of the through hole protrudes outwards towards the outer side of the shell to form the boss part.

In summary, the door panel assembly of the welding machine and the welding machine provided by the utility model at least have the following advantages:

the door plant subassembly and the welding machine of the welding machine disclosed in this embodiment set up boss portion through the border at the through-hole, and the orthographic projection of hasp up end can cover this boss portion simultaneously to make the water that the hasp up end dropped can be blocked outside by boss portion, can not be inside by through-hole infiltration welding machine, promoted the waterproof performance of door plant subassembly, also improved the waterproof performance of welding machine.
