The preferred embodiments of the present invention are shown in the drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete. The following directions such as "axial direction", "above", "below", etc. are all for showing the structural position relationship more clearly, and are not limiting to the present invention. In the present invention, the terms "vertical", "horizontal" and "parallel" are defined as: including ± 30% of cases on the basis of the standard definition. For example, vertical generally refers to an angle of 90 degrees relative to a reference line, but in the present invention, vertical refers to a condition that includes within 60 degrees to 120 degrees.

Referring to fig. 15, in one embodiment, the present invention provides a packaging structure, which includes a first supporting structure 1 and a box body 3, wherein, in use, the first supporting structure 1 is disposed in the box body 3.

Referring to fig. 1 to 7, the first supporting structure 1 has a first end portion and a second end portion, and the first end portion and the second end portion are respectively a front surface and a back surface of the first supporting structure 1. The first end portion is provided with a plurality of first grooves 11, the first grooves 11 are configured to accommodate tubular objects (such as fragile objects like straight tube lamps, and the like, and the fluorescent tube is described below as an example), and the fluorescent tube is placed in the first grooves 11 to limit the movement of the fluorescent tube in the radial direction thereof, so as to limit and fix the fluorescent tube. The fluorescent lamp tube is prevented from being broken due to collision caused by ineffective fixation after being packaged. The first grooves 11 are arranged in parallel to ensure that the fluorescent tubes do not interfere with each other after being placed.

Referring to fig. 2, the first recess 11 includes a first arc-shaped portion 111, and the diameter of the first arc-shaped portion 111 matches that of the fluorescent tube, that is, the diameter of the first arc-shaped portion 111 is equal to or greater than that of the fluorescent tube, so as to better fit the fluorescent tube. In other embodiments, the first groove 11 includes a plurality of first arc-shaped portions 111, and the plurality of first arc-shaped portions 111 are concentrically arranged and have the same diameter. For better placement of the fluorescent tube, regardless of the one or more first arc-shaped parts 111, the sum of the central angles of all the first arc-shaped parts 111 is greater than 150 degrees and less than 180 degrees, preferably, the sum of the central angles of all the first arc-shaped parts 111 is greater than 165 degrees and less than 180 degrees, and more preferably, the sum of the central angles of all the first arc-shaped parts 111 is greater than 175 degrees and less than 180 degrees. Therefore, the fluorescent tube can be better supported, the fluorescent tube can be more stably fixed, and the fluorescent tube is not easy to move in the radial direction of the fluorescent tube due to stress after being placed in the first groove 11. In addition, if the diameter of the first arc-shaped portion is too large, i.e. too large than the diameter of the fluorescent tube, the fluorescent tube is likely to roll when being placed. Therefore, in the present embodiment, the diameter of the first arc-shaped portion 111 should preferably be less than 1.1 times the diameter of the fluorescent tube.

Referring to fig. 2, the ratio of the distance between the centers of the first arc-shaped parts 111 of two adjacent first grooves 11 to the radius of the first arc-shaped parts 111 is 2.05-2.5: 1, preferably 2.1-2.4: 1, more preferably 2.3-2.4: 1, so that after two adjacent fluorescent tubes are placed in the adjacent first grooves 11, a proper distance can be kept between the two adjacent fluorescent tubes, thereby avoiding the situation that the two adjacent fluorescent tubes are damaged due to collision after the first supporting structure 1 is deformed due to stress caused by over-short distance between the two adjacent fluorescent tubes, saving space, and accommodating more fluorescent tubes in a unit space, namely, the fluorescent tubes are placed more compactly, and improving the loading capacity and the conveying efficiency.

Referring to fig. 2, a first support part 13 is provided on the second end of the first support structure 1 so that the first support structure 1 can be placed through the first support part 13. In use, a plurality of first support structures 1 may be stacked in a vertical direction.

Referring to fig. 2, the first supporting portion 13 is provided with a second groove 12, and the opening direction of the second groove 12 is opposite to the opening direction of the first groove 11 in the same first supporting structure 1. When in use, at least two first supporting structures 1 are overlapped, and the first groove 11 of one first supporting structure 1 corresponds to the second groove 12 of the other opposite first supporting structure 1, so that the lower part of the fluorescent tube between the two first supporting structures 1 which are overlapped up and down is supported and limited by the first groove 11, and the upper part is supported and limited by the second groove 12. From the aspect of placing the fluorescent tube, after the upper part of the fluorescent tube is supported and limited by the second groove 12, on one hand, the movement of the fluorescent tube in the width direction is further limited, and on the other hand, the movement of the fluorescent tube in the up-and-down direction is limited.

During this interval, first support structure 1 not only can be better the control holistic height, and provide the effective support restriction to fluorescent tube, and if the central angle is big, then mean that, need set up higher height with first support structure 1, design second arc portion 121, if undersize, then on the one hand can't effectively guarantee the area of contact of fluorescent tube with second arc portion 121, on the other hand can't effectively support restriction fluorescent tube.

Referring to fig. 1 and 7, the first pocket 11 has an inner wall having first main support ribs 112, the first main support ribs 112 being spaced apart in an axial direction of the first pocket 11, and first arc-shaped parts 111 being formed on the first main support ribs 112. By providing the primary first primary support ribs 112, the structural strength is higher than if the inner wall of the first recess 11 were provided as a smooth surface.

Referring to fig. 7, the inner wall has first auxiliary support ribs 113, and a plurality of first auxiliary support ribs 113 are disposed between two adjacent first main support ribs 112 to support the portion of the fluorescent lamp tube located between the two first main support ribs 112, so as to prevent the portion from being easily damaged due to suspension, and the arrangement of the first auxiliary support ribs 113 plays a role in increasing the structural strength.

In other embodiments, the third groove 21 includes a plurality of third arc-shaped portions 211, and the plurality of third arc-shaped portions 211 are concentrically arranged and have the same diameter. For better placement of the fluorescent tube, regardless of the one or more third arc-shaped parts 211, the sum of the central angles of all the third arc-shaped parts 211 is greater than 150 degrees and less than 180 degrees, preferably, the sum of the central angles of all the third arc-shaped parts 211 is greater than 165 degrees and less than 180 degrees, more preferably, the sum of the central angles of all the third arc-shaped parts 211 is greater than 175 degrees and less than 180 degrees. Therefore, the fluorescent tube can be better supported, the fluorescent tube can be more stably fixed, and the fluorescent tube is not easy to move in the width direction of the fluorescent tube due to stress after being placed in the third groove 21.
