[0031] In this embodiment, a pull ring 235 is fixedly installed at the rear end of the insertion post 232 through the mounting bracket 231, a retaining ring 233 is fixedly installed on the outside of the insertion post 232, and a spring 234 is sleeved on the outside of the insertion post 232.

[0032] Spring 234 pushes retaining ring 233 to move by its own elastic force. Retaining ring 233 drives insert post 232 to move synchronously, so that insert post 232 passes through the mounting hole of standard box and puts the perforated corner protector against the vertical rod side of standard box. Insert post 232 passes through the inside of waist hole 32. When the wrong corner protector is picked up, insert post 232 will not pass through the inside of corner protector, so that corner protector cannot be against the vertical rod side of standard box. This avoids picking the wrong corner protector when installing between corner protector and standard box, and reduces rework rate.

[0033] In this embodiment, the fixing unit 21 includes a mounting sleeve 211 installed on the crossbar of the standard box frame. A lead screw 212 is rotatably installed inside the mounting sleeve 211.

[0034] The mounting sleeve 211 is inserted into the crossbar of the standard box 1. The handwheel 213 is turned to drive the lead screw 212 to rotate. The rotation of the lead screw 212 pushes the clamping plate 214 to move and clamp and fix the crossbar of the standard box 1, thereby fixing the device.

[0035] In this embodiment, the adapter unit 22 includes a fixed base 221 fixedly installed on the rear side of the mounting sleeve 211. A rotating base 222 is fixedly installed on the rear side of the fixed base 221 by bolts. A set of insertion holes 223 are symmetrically opened inside the rotating base 222. A rotating rod 224 is rotatably installed inside the rotating base 222. A through hole 225 is opened inside the rotating rod 224. The rotating rod 224 and the rotating base 222 are fixed by inserting a pin 226 into the insertion hole 223 and the through hole 225.

[0037] In this embodiment, a sliding groove 227 is provided inside the rotating rod 224, and a sliding sleeve 228 is slidably sleeved outside the sliding groove 227. A sliding plate 229 is slidably installed inside the sliding sleeve 228, and the sliding plate 229 slides up and down inside the sliding sleeve 228 and slides left and right inside the sliding groove 227.

[0038] The sliding sleeve 228 slides left and right outside the rotating rod 224, and the sliding plate 229 slides up and down in the sliding sleeve 228 and slides left and right inside the sliding groove 227, thereby driving the positioning unit 23 to move up, down, left and right, so as to adapt to the mounting holes of different standard boxes and facilitate the positioning and welding of the armor.

[0039] This utility model also discloses a corner protector for a standard car KD packaging box, including a corner protector body 31. The corner protector body 31 has two waist holes 32 inside, which enable the corner protector body 31 to be fixedly installed on the standard box 1, and the other side of the corner protector body 31 is welded to the standard box 1.

[0040] The corner protector has symmetrical double waist holes on one side, thus making the corner protector usable on both sides.

[0041] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0042] During operation, firstly, depending on the installation direction of the corner protector, rotate the rotating rod 224 to the left or right of the rotating seat 222, and fix the rotating rod 224 by inserting the pin 226 into the insertion hole 223 and the through hole 225. Then, insert the mounting sleeve 211 onto the crossbar of the standard box 1, push the mounting sleeve 211 so that one end of the rotating rod 224 abuts against the side bar installed at a right angle to the crossbar of the standard box 1. By rotating the handwheel 213, the lead screw 212 is driven to rotate. The rotation of the lead screw 212 pushes the clamping plate 214 to move and clamp and fix the crossbar of the standard box 1.

[0043] Then, pull the pull ring 235 to make the retaining ring 233 compress the spring 234 and slide left and right on the outside of the rotating rod 224 through the sliding sleeve 228. The sliding plate 229 slides up and down in the sliding sleeve 228 and slides left and right inside the sliding groove 227, driving the positioning unit 23 to move up, down, left and right, so that the insertion post 232 is aligned with the mounting hole of the standard box.

[0044] Finally, the user releases the pull ring 235, and the spring 234 pushes the retaining ring 233 and the insert post 232 to move through its own elasticity, so that the insert post 232 is inserted into the mounting hole of the standard box, and the perforated corner protector is placed against the vertical rod side of the standard box, so that the insert post 232 passes through the inside of the waist hole 32, and the welding of the corner protector is completed.
