The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0034] Please refer to Figures 1 to 5 at the same time. An embodiment of the present application provides a lens packaging box with adjustable installation gap, including a detachably connected upper cover 1 and a lower box body 2.

[0035] The lower case 2 defines a housing cavity, which is equipped with at least one divider block 4. Each divider block 4 is spaced apart and divides the housing cavity into a plurality of slots. Each slot can accommodate a row of lenses, and the lenses are arranged along the length of the slot to maximize space utilization. Slots 203 are defined on the sidewalls of the divider blocks 4 and the lower case 2 corresponding to the slots. The slots 203 on either side of the same slot face each other, forming a secure space for securing the lenses. When a lens is placed within the secure space, the slots 203 are squeezed and deformed to secure the lens. The lens's securement relies on the elasticity of the material of the lower case 2, providing a good hold.

[0036] A first clamping portion 201 is formed on the lower box body 2, which is compatible with the second clamping portion 101 on the upper cover 1 and serves to fix the upper cover 1 and the lower box body 2. A first limiting protrusion 202 is formed on the lower box body 2, which is compatible with the second limiting protrusion 102 on the upper cover 1 and serves to limit and seal the box body. Considering the box-like structure, the number of the first clamping portions 201 is specifically provided in two, respectively, and is respectively arranged on two opposite sides, and their arrangement direction is symmetrical along the center of the lower box body 2. The number of the first limiting protrusions 202 is also provided in two, and is also arranged on two opposite sides of the lower box body 2 and their arrangement direction is symmetrical along the center of the lower box body 2. In addition, considering the sealing effect, each first limiting protrusion 202 is connected to one of the first clamping portions 201 at the corner of the lower box body 2.

[0037] Referring to Figure 2 , the upper cover 1 is formed with a second engaging portion 101. The first engaging portion 201 and the second engaging portion 101 engage with each other to limit the relative position of the upper cover 1 and the lower housing 2 in a first direction. A second limiting protrusion 102 is formed on the upper cover 1. The first limiting protrusion 202 is configured to abut against the second limiting protrusion 102 to limit the relative position of the upper cover 1 and the lower housing 2 in a second direction. In this embodiment, the first direction specifically refers to the direction of connection between the first and second engaging portions 201 and 101, and the second direction is perpendicular to the first direction.

[0038] Please refer to Figure 3. The first clamping part 201, the second clamping part 101, the first limiting protrusion 202, and the second limiting protrusion 102 enclose each other and seal the lower box body 2, so that after installation, the lower box body 2 is isolated from the outside to prevent dust and other impurities from contaminating the lens. The upper cover 1 and the lower box body 2 are respectively integrally formed for easy manufacturing. The upper cover 1 and the lower box body 2 are both made of PU (polyurethane) material. The full name of PU material is polyurethane, which is a polymer compound. Soft polyurethane is mainly a thermoplastic linear structure. It has better stability, chemical resistance, resilience and mechanical properties than PVC (polyvinyl chloride) foam material, and has smaller compression deformation. It has good heat insulation, sound insulation, shock resistance and anti-toxic properties, so it has a good protective effect when used as packaging.

[0039] Please refer to Figure 4. A connecting assembly is provided in the lower box body 2 to enable a detachable connection between the partition block 4 and the lower box body 2. A connecting groove 204 is provided at the bottom of the lower box body 2. The connecting assembly is built into the connecting groove 204. The connecting groove 204 is communicated with the accommodating cavity, and a connecting portion is formed on the partition block 4. The connecting assembly includes an adjusting rod 5 and a nut 51. The adjusting rod 5 is rotatably connected to the connecting groove 204, wherein the nut 51 is threadedly connected to the adjusting rod 5, the connecting portion is slidably matched with the connecting groove 204, and the connecting portion is engaged with the nut 51 to limit the rotation of the nut 51. A limiting protrusion is formed on the nut 51. The limiting protrusion is used to limit the displacement of the partition block 4 in the axial direction of the adjusting rod 5. When the adjusting rod 5 rotates, 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 ways to adjust the nut 51: one is when the partition block 4 is detached, then the nut 51 can be rotated to adjust it; the other is when the partition block 4 and the nut 51 are connected, then the rotation of the adjustment rod 5 can drive the partition block 4 to move horizontally, thereby adjusting the size of the accommodation space of different columns to accommodate lenses of different specifications.

[0040] One end of the adjustment rod 5 passes through the side wall of the lower case 2 and is provided with a movable lock. The movable lock includes a force ring 52 and an elastic member (not shown). The force ring 52 is rotatably connected to the end face of the adjustment rod 5. The elastic member is used to apply elastic force to the force ring 52 so that the side surface of the force ring 52 abuts against the side surface of the lower case 2. The elastic member is specifically configured as a torsion spring, so that the position of the force ring 52 in the natural state can be locked, thereby fixing the relative position of the adjustment rod 5.

[0041] Each fixed space is provided with a shock absorbing member 3 , which is detachably connected to the connecting groove 204 and covers the connecting groove 204 . The shock absorbing member 3 is provided with a plurality of shock absorbing grooves 301 , which correspond to the fixed spaces one by one.

[0042] As shown in Figure 5, an adjustment assembly is provided within the lower housing 2. The adjustment assembly corresponds to the spacer 4 one-to-one. Each slot 203 of the spacer 4 is equipped with an airbag 41. The length of the slot 203 exposed by the airbag 41 represents the actual clamping length. When the nut 51 moves along the axis of the adjustment rod 5, the nut 51 drives the adjustment assembly to adjust the airbags 41 on both sides of the spacer 4 in opposite directions, causing the actual clamping lengths on both sides of the spacer 4 to change in opposite directions. The arrangement of the adjustment assembly takes into account that when the spacer 4 moves, the size of each fixed space changes, while the length of each slot 203 remains unchanged. Especially when the fixed space is small, the relatively long slots 203 can cause difficulties in handling. When handling small lenses, the contact surface with the lens is very limited, which can easily make it difficult to remove or damage the lens. The number of adjustment assemblies can be less than the number of spacers 4. Furthermore, the airbags 41 on both sides have an initial air content and automatically seal when disconnected from the adjustment assembly to prevent air leakage.

[0043] The adjustment assembly includes two cylinders 6, each with its piston fixedly connected to a corresponding nut 51. Air tubes 61 are connected to the cylinders 6. These tubes are detachably connected to the divider block 4 and communicate with the airbags 41 on either side of the divider block 4. When the nut 51 slides, the volumes of the two cylinders 6 change in opposite directions, causing the volumes of the airbags 41 on either side of the divider block 4 to change in opposite directions. The detachable connection between the air tubes 61 and the divider block 4 allows for adjustable expansion or contraction of the airbags 41.

[0044] Working principle:

[0045] When packaging lenses using the present invention, first select the corresponding lower box body 2 according to the lens specifications and select the corresponding number of dividers 4 for assembly. First, rotate the nut 51 to a preliminary position, and then assemble the dividers 4 and nut 51. After assembly, use the lens to test the position of each divider 4 to ensure it is properly positioned. If there is a slight error, the adjustment rod 5 can be used to drive each divider 4 to move synchronously to the appropriate position. The lens is inserted according to the position of the locking slots 203. Each locking slot 203 fixes one side of the lens. When the lens is inserted, the locking slots 203 can deform to secure the lens. After the lens is placed, the upper cover 1 and lower box body 2 are fixed. First, place the upper cover 1 on the lower box body 2, as shown in the upper portion of Figure 3. At this time, the first locking portion 201 and the second locking portion 101 are aligned. Push the upper cover 1 and lower box body 2 in the direction of relative movement. The first locking portion 201 and the second locking portion 101 move relative to each other until they engage, and the packaging is complete. When the upper cover 1 and lower box body 2 need to be opened, the reverse operation is performed.

[0046] The above are only preferred embodiments of the present application. The scope of protection of the present application is not limited to the above embodiments. All technical solutions based on the concept of the present application are within the scope of protection of the present application. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present application should also be considered within the scope of protection of the present application.
