The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0031] Please refer to Figures 1 to 5 The embodiment provides a lens packaging box with adjustable installation gap, which comprises an upper cover 1 and a lower box body 2 which are detachably connected.

[0032] The lower box body 2 is provided with a containing cavity, and at least one partition block 4 is arranged in the lower box body 2. The partition blocks 4 are arranged at intervals and divide the containing cavity into a plurality of containing grooves. One containing groove corresponds to one row of lenses, and the lenses are arranged along the length direction of the containing groove to obtain the maximum space utilization. The partition blocks 4, the lower box body 2 and the side walls corresponding to the containing grooves are all provided with clamping grooves 203. The clamping grooves 203 on the two sides of the same containing groove are opposite to each other and form a fixing space for fixing the lenses. When the lenses are placed in the fixing space, the clamping grooves 203 are extruded and deformed to fix the lenses. The fixing of the lenses depends on the elasticity of the material of the lower box body 2, thereby being able to provide a better fixing effect on the lenses.

[0033] The lower box body 2 is provided with a first clamping part 201 which is matched with the second clamping part 101 on the upper cover 1 and is used for fixing the upper cover 1 and the lower box body 2. The lower box body 2 is provided with a first limiting protrusion 202 which is matched with the second limiting protrusion 102 on the upper cover 1 and is used for limiting and closing. Considering the box structure, the number of the first clamping parts 201 is two, which are arranged on opposite sides and are arranged along the center symmetry of the lower box body 2. The number of the first limiting protrusions 202 is also two, which are arranged on opposite sides of the lower box body 2 and are arranged along the center symmetry of the lower box body 2. In addition, considering the closing effect, each first limiting protrusion 202 is connected with one first clamping part 201 at the corner of the lower box body 2.

[0034] Please refer to Figure 2 The upper cover 1 is provided with a second clamping part 101. The first clamping part 201 and the second clamping part 101 are matched with each other to limit the relative position of the upper cover 1 and the lower box body 2 in the first direction. The upper cover 1 is provided with a second limiting protrusion 102. The first limiting protrusion 202 is used for abutting against the second limiting protrusion 102 to limit the relative position of the upper cover 1 and the lower box body 2 in the second direction. In the embodiment, the first direction is the connecting direction of the first clamping part 201 and the second clamping part 101, and the second direction is perpendicular to the first direction.

[0035] Please refer to Figure 3The first clamping portion 201, the second clamping portion 101, the first limiting protrusion 202 and the second limiting protrusion 102 are mutually enclosed and seal the lower box body 2, so that after installation, the lower box body 2 is isolated from the outside, and dust and other impurities are prevented from polluting the lenses. The upper cover 1 and the lower box body 2 are integrally formed, which is convenient for manufacturing. The upper cover 1 and the lower box body 2 are both made of PU material. The full name of PU material is polyurethane, which is a high molecular compound. The soft polyurethane mainly has a thermoplastic linear structure, which has better stability, chemical resistance, resilience and mechanical properties than PVC foaming material, and has smaller compression deformation. It has good heat insulation, sound insulation, shock resistance and anti-toxicity, and therefore has good protection effect when used for packaging.

[0036] Please refer to Figure 4 The lower box body 2 is provided with a connecting assembly for detachable connection between the partition block 4 and the lower box body 2. The lower box body 2 is provided with a connecting groove 204 at the bottom, and the connecting assembly is arranged in the connecting groove 204. The connecting groove 204 is in communication with the accommodating cavity, and the connecting assembly is formed on the partition block 4. The connecting assembly comprises an adjusting rod 5 and a nut 51. The adjusting rod 5 is rotatably connected with the connecting groove 204. The nut 51 is threadedly connected with the adjusting rod 5. The connecting portion is slidably connected with the connecting groove 204. The connecting portion is clamped with the nut 51 to limit the rotation of the nut 51. The nut 51 is provided with a limiting protrusion for limiting the displacement of the partition block 4 in the axial direction of the adjusting rod 5. When the adjusting rod 5 is rotated, the nut 51 slides along the axial direction of the adjusting rod 5 to drive the partition block 4 to slide synchronously. There are two adjustment modes of the nut 51: one is that the partition block 4 is separated, and the nut 51 is rotated to adjust; the other is that the partition block 4 is connected with the nut 51, and the rotation of the adjusting rod 5 drives the partition block 4 to translate, so as to adjust the size of the accommodating space of different columns to adapt to lenses of different specifications.

[0037] One end of the adjusting rod 5 penetrates the side wall of the lower box body 2 and is provided with a movable lock buckle. The movable lock buckle comprises a force ring 52 and an elastic member (not shown in the figure). The force ring 52 is rotatably connected with the end surface of the adjusting rod 5. The elastic member is used to provide elastic force to the force ring 52 to make the side surface of the force ring 52 abut against the side surface of the lower box body 2. Specifically, the elastic member is a torsion spring, so that the position of the force ring 52 can be locked in the natural state to fix the relative position of the adjusting rod 5.

[0038] Each fixed space is provided with a damping member 3. The damping member 3 is detachably connected with the connecting groove 204 and covers the connecting groove 204. The damping member 3 is provided with a plurality of damping grooves 301. The damping grooves 301 correspond to the fixed spaces one by one.

[0039] As Figure 5As shown, the lower box body 2 is provided with an adjusting assembly, the adjusting assembly and the partition block 4 are one-to-one corresponding, the air bag 41 is arranged in each clamping groove 203 of the partition block 4, and the exposed length of the clamping groove 203 from the air bag 41 is the actual clamping length. When the nut 51 moves along the axis direction of the adjusting rod 5, the nut 51 drives the adjusting assembly to adjust the air bags 41 on both sides of the partition block 4 to change reversely so that the actual clamping length on both sides of the partition block 4 changes reversely. The adjusting assembly is arranged considering that when the partition block 4 moves, the size of each fixed space changes, and the length of each clamping groove 203 does not change. Especially when the fixed space is small, the relatively long length of the clamping groove 203 will bring difficulty in taking and placing. When taking and placing small size lenses, the contact surface with the lens is very limited, which is easy to cause the lens to be difficult to take out or damaged. The number of the adjusting assembly can be less than the number of the partition block 4. In addition, the air bags 41 on both sides have an initial gas content, and can automatically close to avoid gas leakage when being separated from the adjusting assembly.

[0040] The adjusting assembly includes two air cylinders 6, the pistons of the two air cylinders 6 are fixedly connected with corresponding nuts 51, the air cylinder 6 is communicated with a gas guide pipe 61, the gas guide pipe 61 is detachably connected with the partition block 4 and is communicated with the air bag 41 on one side of the partition block 4. When the nut 51 slides, the volumes of the two air cylinders 6 change reversely to make the volumes of the air bags 41 on both sides of the partition block 4 change reversely. The detachable connection between the gas guide pipe 61 and the partition block 4 makes the expansion or contraction amplitude of the air bag 41 adjustable.

[0041] Working principle:

[0042] When the lenses are packaged by using the application, first, the corresponding lower box body 2 is selected according to the specifications of the lenses, and the corresponding number of partition blocks 4 are assembled. The nut 51 is first rotated to a preliminary position, and then the partition block 4 and the nut 51 are assembled. After assembly is completed, whether the positions of each partition block 4 are appropriate is tested by using the lenses. If there is a slight error, each partition block 4 can be synchronously moved to the appropriate position by using the adjusting rod 5. According to the position of the clamping groove 203, the lens is inserted, each clamping groove 203 respectively fixes one side of the lens, and when the lens is inserted, the clamping groove 203 can be deformed to fix the lens. After the lenses are placed, the upper cover 1 and the lower box body 2 are fixed. First, the upper cover 1 is placed on the lower box body 2 as shown in the upper part, at this time, the first clamping part 201 and the second clamping part 101 are arranged opposite to each other. The upper cover 1 and the lower box body 2 are pushed in the direction of relative movement, and the first clamping part 201 and the second clamping part 101 are relatively moved to be clamped with each other, and thus the packaging is completed. When the upper cover 1 and the lower box body 2 need to be opened, the reverse operation can be performed. Figure 3
