  • DETAILED DESCRIPTION
  • The technology, the structural feature, and the aim and effect achieved of the invention will be described in detail in accordance with the specific examples and the figures.
  • As shown in FIG. 1, in a first preferred example of an EPP box of the invention, the EPP box 100 comprises a box bottom 10 and a plurality of side walls removably arranged at the box bottom 10; the plurality of side walls are connected pairwise to form a removable frame 30.
  • The box bottom 10 is of a plate. The plate can be a rectangular plate, circular plate, or plate and the like in accordance with the requirement of components to be assembled. In the first preferred example, the box bottom 10 is a rectangular plate. The panel surface of the box bottom 10 close to the periphery thereof is provided with a plurality of clip holes 12. In the first example, the four corners of the rectangular plate are provided with one clip hole 12, and all the sides of the rectangular plate are provided with at least one clip hole 12.
  • The plurality of side walls may be different in length. In the first preferred example, the side walls are four in number and comprise two first side walls 22 arranged oppositely and two second side walls 24 arranged oppositely. Each first side wall 22 is formed with a first clip tenon 222 and a first clip hole 224. The first clip tenon 222 is formed on the bottom of the first side wall 22 for clamping the corresponding clip hole 12 in the box bottom 10. The first clip hole 224 faces the second side wall 24 for clamping the second side wall 24. Each second side wall 24 is formed with second clip tenon(s) 242 and third clip tenon(s) 244, and the second clip tenon 242 is formed on the bottom of the second side wall 24 for clamping the corresponding clip hole 12 in the box bottom 10. The third clip tenons 244 are respectively formed on both ends of the second side wall 24 and face each first side wall 22, respectively, for clamping the corresponding first clip holes 224 in the first side wall 22.
  • As shown in FIG. 1 to FIG. 3, when the EPP box 100 is assembled, the third clip tenons at one end of the second side wall 24 are respectively clamped in the first clip holes 224 in the same side of one first side wall 22, and the third clip tenons 244 at the other end of the second side wall 24 are respectively clamped in the first clip holes 224 of the other first side wall 22. Thus, the first side walls 22 and the second side walls 24 are connected to form the frame 30. Then, the frame 30 and the box bottom 10 are assembled, and the first clip tenons 222 of the first side walls 22 and the second clip tenons 242 of the second side walls 24 are respectively and correspondingly clamped in the clip holes 12 in the box bottom 10. Therefore, the EPP box 100 is assembled.
  • Because the first side wall 22 and the second side wall 24, the first side wall 22 and the box bottom 10, and the second side wall 24 and the box bottom 10 are connected by clips, the EPP box is conveniently disassembled. In the first preferred example, the frame 30 is formed by four side walls. One of ordinary skilled in the art can understand that the four side walls can be single structures respectively, the structures can be different, and the two opposite side walls can be of dissymmetrical structure; the four side walls can be of two symmetrical structures, and thus only two set of mold is required to be developed when making the side walls. If the four side walls are of the same structure, only a set of mold is required to be developed when making the side walls. In the first preferred example, the side walls are of two symmetrical structures. The box bottom and the side wall or the adjacent side walls themselves are connected by clips, namely one is provided with clip tenons and the other is correspondingly provided with clip holes. The structure of the clip tenons can be various, for example, the structure of the clip tenons can be cylinder, or stereo fillet, or swallowtail butterfly. Each clip hole should be of a structure matching with the structure of the clip tenon. The positions of the clip tenons and the clip holes can be exchanged; if the first side wall 22 is connected with the second side wall 24, the first side wall 22 is provided with second clip tenons 242, thus the second side wall 24 should be correspondingly provided with first clip holes 224.
  • As shown in FIG. 4, in a second preferred example of an EPP box of the invention, the structure of the EPP box 200 is approximately the same as that of the EPP box 100. The structure of the EPP box 200 is different from that of the EPP box 100 in that: in the second preferred example, the EPP box 200 further comprises a box cover 40, to ensure the box cover 40 is stably covered on the frame 30. The top surfaces of the first side wall 22 and the second side wall 24 are respectively formed with flanges 32, and the bottom of the box cover 40 is correspondingly provided with grooves (not shown in the figure) to match with the flanges 32. By covering the box cover 40 on the frame 30, the components arranged in the frame 30 can be further protected. Thus, the box cover 40 plays a role of fixation and dust prevention. Understandably, the bottom of the box cover 40 can be formed with flange(s), and the top surface of the frame 30 can be correspondingly provided with groove(s).
  • As shown in FIG. 5, in a third preferred example of an EPP box of the invention, the structure of the EPP box 300 is approximately the same as that of the EPP box 200. The structure of the EPP box 300 is different from that of the EPP box 200 in that: the frame 30 is only composed of two symmetrical side walls 52. Thus, only a set of mold is required to be developed when making the side walls, thereby greatly saving the manufacturing cost.
  • To sum up, the EPP box of the invention is provided with a plurality of side walls, the plurality of side walls are removably connected to form the frame for arranging components such as LCD panels. The dimension of each side wall is accurately controlled by individually making the side walls, and the internal dimension of the frame is easily controlled and regulated. In addition, only the damaged side wall(s) is replaced when part of the EPP box is damaged while in use without discarding the whole box body, the box body is easily maintained, and the production cost is greatly reduced.
