Detailed Description

In order that the above objects, features and advantages of the utility model will be readily understood, a more particular description of the utility model will be rendered by reference to the appended drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model. The present utility model may be embodied in many other forms than described herein and similarly modified by those skilled in the art without departing from the spirit of the utility model, whereby the utility model is not limited to the specific embodiments disclosed below.

It will be understood that when an element is referred to as being "fixed" or "disposed" on another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like are used herein for illustrative purposes only and are not meant to be the only embodiment.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model belongs. The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1-2, a double-box structure for transporting precision parts comprises an outer box 1 and an inner box 2, wherein the outer box 1 is wooden, a cavity is formed in the outer box, the inner box 2 is installed in the cavity, a heat conducting screw 3 is installed on the side wall of the outer box 1, the heat conducting screw 3 penetrates through the side wall of the outer box 1 and is abutted to the outer wall of the inner box 2, the inner box 2 comprises a box 21 and a box cover 22, the box 21 is hollow and internally provided with ribs, the box cover 22 is detachably installed on the box 21 through bolts, a plurality of buffer parts 221 are further arranged on the box cover 22, a base plate 211 is arranged in the box 21, and the buffer parts 221 penetrate through the box cover 22 and are connected with the base plate 211. Specifically, in this embodiment, when boxing, the inner box 2 is loaded in the cavity of the outer box 1, the outer box 1 is a wooden box, a spliced wooden board design can be adopted, a cavity is reserved in the inner box, and after the inner box 2 is loaded with a precision piece and placed in the cavity, the outer box 1 is covered and packaged. The heat conduction screw 3 is installed at the lateral wall of outer box 1, and heat conduction screw 3 runs through the lateral wall of outer box 1, in the lug insert cavity for cavity and external temperature accessible heat conduction screw 3 keep synchronous, avoid in long-time transportation or storage process, the inconsistent temperature difference of outer box 1 inside and outside leads to outer box 1 to take place deformation. When the temperature is low, the wood board of the outer box body 1 can shrink, otherwise, when the temperature is high, the thermal expansion phenomenon can occur. Therefore, when in transportation and storage, the heat conducting screw 3 can balance the temperature inside and outside the outer box body 1, so that the temperature inside and outside the outer box body can quickly and consistently reach the temperature, and the temperature difference is avoided. And use heat conduction screw rod 3 and interior box 2 lateral wall butt, can tighten interior box 2, avoid interior box 2 and the plank inner wall contact of outer box 1, anti-adhesion makes things convenient for the dismouting.
