[0002] The panel box belongs to a recyclable and reusable packaging box, which is composed of a base, a cover and a panel. The packaging box can be formed by unfolding the panel and combining the base and the cover, and is used for packaging and transporting products. The base, the cover and the panel of the panel box on the market are of fixed sizes, so the overall volume is also fixed. When the load is small or the volume is small, the large volume inside the box is wasted. When the load is large or the volume is large, the space inside the box is insufficient, and the use is not convenient.

[0003] A patent with the publication number CN220032534U discloses a plastic panel box with adjustable size, which comprises a base, a bottom frame fixedly connected to the top outer wall of the base, an inner frame body clamped in the bottom frame, an outer frame body sleeved with the side wall of the inner frame body, a plurality of guide grooves formed in the outer wall of the inner frame body, a plurality of guide blocks matched with the guide grooves arranged on the inner wall of the outer frame body, a plurality of fixing bolts threadedly connected to the outer wall of the outer frame body, a plurality of limiting grooves formed in the inner wall of the outer frame body, a plurality of limiting bolts threadedly connected to the inner wall of the inner frame body, a box cover arranged at the top end of the outer frame body, and an embedded frame fixedly connected to the bottom outer wall of the box cover.

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0031] Please refer to Figure 1 - Figure 7 The embodiment provides a space-adjustable fence box, which comprises a base 1, an inner frame body 2 installed on the base 1, an outer frame body 3 sleeved outside the inner frame body 2, and an upper cover 4 installed on the top of the outer frame body 3, and the inner frame body 2 and the outer frame body 3 are in sliding connection; specifically, a vertical first dovetail sliding groove 10 is formed in one of the inner frame body 2 or the outer frame body 3, and the other is fixedly connected with a first sliding bar matched with the first dovetail sliding groove 10, the vertical sliding between the inner frame body 2 and the outer frame body 3 is constrained through the cooperation of the first dovetail sliding groove 10 and the first sliding bar, and it is ensured that the outer frame body 3 can linearly ascend and descend along the first dovetail sliding groove 10.

[0032] The inner frame 2 is provided with vertical installation grooves 21 on four sides, and the installation grooves 21 are fixedly connected with adjusting racks 5; the outer frame 3 is fixedly connected with an installation frame 6 on the side, and the installation frame 6 is rotatably connected with adjusting gears 7 which are engaged with the adjusting racks 5; the adjusting racks 5 on the four sides of the inner frame 2 are correspondingly provided with the adjusting gears 7, and the installation frame 6 is provided with a first driving member 8 for driving all the adjusting gears 7 to rotate synchronously at the same speed; specifically, the first driving member 8 comprises four rotating shafts 81, the adjusting gears 7 are coaxially fixedly connected with the rotating shafts 81, and the adjacent two rotating shafts 81 are drivingly connected through bevel gear sets 13; the four rotating shafts 81 are respectively rotatably connected to the four sides of the installation frame 6, at least one rotating shaft 81 is coaxially fixedly connected with a first worm wheel 82, and the installation frame 6 is rotatably connected with a first worm 83 which is coaxially fixedly connected with the first worm wheel 82.

[0033] The installation frame 6 is slidingly connected with a locking tooth plate 9 on the bottom surface which is perpendicular to the side surface of the outer frame 3; specifically, the installation frame 6 is provided with a second dovetail sliding groove 61 on the bottom surface, and the bottom of the locking tooth plate 9 is fixedly connected with a second sliding strip 91 which is matched with the second dovetail sliding groove 61; the locking tooth plate 9 is slidingly connected to the bottom surface of the installation frame 6 through the cooperation of the second sliding strip 91 and the second dovetail sliding groove 61; in addition, the locking tooth plate 9 corresponds to the adjusting rack 5 in position; it should be noted that the number of the locking tooth plate 9 matches the number of the adjusting rack 5, that is, each locking tooth plate 9 corresponds to an adjusting rack 5 in position; the installation frame 6 is also provided with a regulating mechanism for driving all the locking tooth plates 9 to engage with the adjusting racks 5.

[0034] Further, since the adjusting rack 5 is located on the inner frame 2, a retreat hole 31 is provided on the side surface of the outer frame 3 for installation; the locking tooth plate 9 and the adjusting gear 7 are matched with the adjusting rack 5 after passing through the retreat hole 31.

[0035] Specifically, referring to Figure 1 - Figure 7 The regulating mechanism comprises a locking member 11 for driving the locking tooth plate 9 to move, the locking member 11 comprises a fixed ring 111 fixedly connected to the inner side surface of the installation frame 6, a bearing 112 is fixedly installed in the fixed ring 111, a threaded sleeve 113 is coaxially fixedly connected to the inner ring of the bearing 112, a screw rod 114 is threadedly connected in the threaded sleeve 113, the screw rod 114 is fixedly connected with the locking tooth plate 9, an adjusting worm wheel 115 is coaxially fixedly connected to the threaded sleeve 113, and an adjusting worm 116 is rotatably connected in the installation frame 6 and engaged with the adjusting worm wheel 115; the regulating mechanism further comprises a second driving member 12 for driving all the adjusting worms 116 to rotate synchronously.

[0036] Further, the second driving member 12 comprises four rotating shafts two 121, the adjusting worm 116 is coaxially fixedly connected with the rotating shaft two 121, and the adjacent two rotating shafts two 121 are connected through the bevel gear set 13; the four rotating shafts two 121 are respectively rotatably connected to the four sides of the mounting frame 6, at least one rotating shaft two 121 is coaxially fixedly connected with a second worm wheel 122, and the mounting frame 6 is rotatably connected with a second worm 123 between the outer frame body 3, and the second worm 123 is meshed with the second worm wheel 122.

[0037] In addition, each bevel gear set 13 comprises two bevel gears which are completely same, so as to ensure that the rotating speeds of the four rotating shafts one 81 are same, and the rotating speeds of the four rotating shafts two 121 are same.

[0038] In the following, further introduction is made in combination with specific use scenarios. When the size of the fence box needs to be adjusted, the user only needs to control the locking tooth plate 9 to be away from the adjusting rack 5 by using the control mechanism, so that the locking between the outer frame body 3 and the inner frame body 2 is released, and then the four sides of the outer frame body 3 are controlled to rotate synchronously and at the same speed by using the first driving member 8, so that the outer frame body 3 is controlled to ascend and descend relative to the inner frame body 2 under the cooperation of the adjusting gear 7 and the adjusting rack 5, thereby adjusting the volume of the fence box, and then the locking tooth plate 9 is controlled to be close to the adjusting rack 5 by using the control mechanism, so that the teeth on the locking tooth plate 9 and the teeth on the adjusting rack 5 are meshed with each other. Since the adjusting rack 5 and the locking tooth plate 9 are meshed with multiple teeth at the same time, the position locking between the outer frame body 3 and the inner frame body 2 is realized by the tooth surface support between the multiple teeth on the locking tooth plate 9 and the multiple teeth on the adjusting rack, and the four sides of the outer frame body 3 and the inner frame body 2 are provided with the locking tooth plate 9 and the adjusting rack 5, so that the relative stability between the outer frame body 3 and the inner frame body 2 is better, and the overall use of the fence box is more stable.

[0039] Specifically, the overall height of the outer frame 3 and the inner frame 2 (i.e. the volume adjustment of the surrounding box) is adjusted by the first driving member 8, and the specific operation is as follows: when the locking between the outer frame 3 and the inner frame 2 is released, the first worm 83 is controlled to rotate, thereby driving one of the rotating shafts 81 to rotate, and the adjacent two rotating shafts 81 are connected through the bevel gear set 13. The two bevel gears of the bevel gear set 13 are exactly the same, so that the rotating speeds of the four rotating shafts 81 are the same. Further, when the first worm 83 is driven to rotate, the four rotating shafts 81 rotate synchronously and at the same speed under the cooperation of the first worm 83 and the first worm gear 82 and the cooperation of the bevel gear set 13 between the adjacent two rotating shafts 81, thereby driving the four sides of the outer frame 3 to rotate synchronously and at the same speed. The adjusting gear 7, then under the meshing cooperation of the adjusting gear 7 and the adjusting rack 5, makes the outer frame 3 relative to the inner frame 2 to ascend and descend, thereby realizing the adjustment of the volume of the surrounding box, and only one person is needed to control the first worm 83 to rotate to realize the adjustment of the volume of the surrounding box. The adjustment process is more convenient.

[0040] Further, the unlocking and locking between the outer frame 3 and the inner frame 2 is controlled by the regulating mechanism, specifically by the second driving member 12 to control the locking members 11 on the four sides of the outer frame 3 to operate, thereby driving the locking tooth plates 9 to move away from the adjusting rack 5 or to move close to the adjusting rack 5 synchronously. The specific unlocking or locking steps are as follows: when the outer frame 3 and the inner frame 2 are in the locked state, the locking tooth plates 9 on the four sides of the outer frame 3 are respectively clamped to the adjusting rack 5, and all the teeth on the locking tooth plate 9 are engaged with the teeth of the adjusting rack 5.

[0041] When the unlocking of the outer frame 3 and the inner frame 2 is performed, the four rotating shafts two 121 are synchronously and uniformly rotated by driving the second worm 123 and then by the cooperation of the second worm 123 and the second worm gear 122 and the cooperation of the bevel gear set 13 between the adjacent two rotating shafts two 121, so as to make the locking pieces 11 on the four sides of the outer frame 3 operate. The operation of the locking pieces 11 when unlocking is as follows: the rotating shafts two 121 are rotated, and then the adjusting worm 116 on the rotating shafts two 121 is synchronously and uniformly rotated, and the cooperation of the adjusting worm 116 and the adjusting worm gear 115 drives the threaded sleeve 113 to rotate. Since the fixed ring 111 is fixedly connected to the inner side of the mounting frame 6, the bearing 112 is fixedly installed in the fixed ring 111, and the threaded sleeve 113 is fixedly connected to the inner ring of the bearing 112, the threaded sleeve 113 can only rotate and cannot move axially. Further, since the threaded sleeve 113 is threadedly connected with the screw rod 114, the screw rod 114 is fixedly connected with the locking tooth plate 9, and the locking tooth plate 9 only translates along the second dovetail sliding groove 61 by the cooperation of the second dovetail sliding groove 61 and the second sliding bar 91, so that when the threaded sleeve 113 rotates, the locking tooth plate 9 moves along the second dovetail sliding groove 61. When unlocking, only by rotating the second worm 123 to control the locking tooth plate 9 to move away from the adjusting rack, the locking between the outer frame 3 and the inner frame 2 is released, and then the first driving piece 8 is used to adjust the height of the outer frame 3 extending relative to the inner frame 2, so as to finally realize the volume adjustment of the fence box. Similarly, when the locking between the outer frame 3 and the inner frame 2 is needed to be performed, only by controlling the second worm 123 to reversely rotate, the locking tooth plate 9 is made to approach the adjusting rack, so that all the teeth on the locking tooth plate 9 are engaged with the teeth of the adjusting rack 5.

[0042] Since the height of the outer frame 3 relative to the inner frame 2 is adjusted by the cooperation of the adjusting gear 7 and the adjusting rack 5, the minimum height of each lifting of the outer frame 3 relative to the inner frame 2 is the tooth width of one tooth of the adjusting rack 5, and the locking between the outer frame 3 and the inner frame 2 is realized by the tooth surface support between the teeth of the locking tooth plate 9 and the teeth of the adjusting rack 5, so that after each lifting of the outer frame 3, all the teeth of the locking tooth plate 9 can be smoothly engaged on the tooth surface of the adjusting rack, and the problem of the tooth top of the locking tooth plate 9 interfering with the tooth top of the adjusting rack does not occur, so that the whole adjusting process of the fence box is relatively stable and smooth.

[0043] Furthermore, the driving of the first rotating shaft 81, the driving of the second rotating shaft 121, and the transmission between the second rotating shaft 121 and the threaded sleeve 113 are all achieved through a worm gear mechanism. This allows the worm gear to utilize its self-locking function to ensure that, during adjustment, as long as the user does not actively drive the first worm 83 and the second worm 123 to rotate, the outer frame 3 will not adjust its height relative to the inner frame 2. The locking and unlocking of the outer frame 3 and the inner frame 2 will also be activated, making the overall volume adjustment process of the enclosure box safer and more stable.

[0044] The locking teeth 9 on the four sides of the outer frame 3 are controlled by the control mechanism to move away from the adjusting rack 5, thereby achieving the locking and unlocking between the outer frame 3 and the inner frame 2. Then, the adjusting gear 7 on the side of the outer frame 3 is controlled to rotate synchronously and at the same speed by controlling the first driving member 8, thereby controlling the outer frame 3 to rise and fall relative to the inner frame 2, thereby adjusting the volume of the enclosure box. Then, the locking teeth 9 on the four sides of the outer frame 3 are controlled by the control mechanism to move synchronously closer to the adjusting rack 5, so that all the teeth on the locking teeth 9 mesh with the teeth on the adjusting rack 5, thereby achieving the locking between the outer frame 3 and the inner frame 2. This application allows only one user to adjust the volume of the enclosure box. The outer frame 3 and the inner frame 2 are connected by locking tooth plates 9 on the four sides of the outer frame 3 and the inner frame 2, which engage with the corresponding adjusting racks 5. The locking between the outer frame 3 and the inner frame 2 is achieved by the tooth surface support between the multiple teeth of each locking tooth plate 9 and the multiple teeth on the adjusting rack, making the locking between the inner frame 2 and the outer frame 3 more stable. Overall, this improves the convenience of adjusting the size of the enclosure box and the installation stability between the outer frame 3 and the inner frame 2.

[0045] Reference Figure 1 - Figure 7 As a specific embodiment of this application, a plurality of mounting slots 21 are provided on each side of the inner frame 2, and an adjusting rack 5 is fixed in each mounting slot 21. Correspondingly, an adjusting gear 7 is provided at each adjusting rack 5. A plurality of locking tooth plates 9 are slidably connected on each side of the mounting frame 6. Correspondingly, each locking tooth plate 9 should have a locking member 11 for adjusting its position.

[0046] In specific usage scenarios, the combination of multiple locking tooth plates 9 and multiple adjusting racks 5 effectively increases the locking area between the outer frame 3 and the inner frame 2, thereby improving the locking stability between the outer frame 3 and the inner frame 2. In addition, the combination of multiple adjusting gears 7 and multiple adjusting racks 5 also increases the locking stability between the outer frame 3 and the inner frame 2 to a certain extent. Furthermore, the combination of multiple adjusting gears 7 and adjusting racks 5 can further increase the balance and stability of the outer frame 3 during its ascent.

[0047] ReferenceFigure 2 、 Figure 4 、 Figure 6 As a specific embodiment of the present application, the adjusting handle 14 is detachably installed at one end of the mounting frame 6 of the first worm 83 and the second worm 123.

[0048] In combination with a specific use scenario, when the volume of the fence box needs to be adjusted, the second worm 123 is first rotated by the adjusting handle 14 to control the rotation of the second rotating shaft 121, and then the locking between the outer frame body 3 and the inner frame body 2 is released, and then the first worm 83 is rotated by the adjusting handle 14 to drive the adjusting gear 7 to rotate, so as to adjust the overall height of the outer frame body 3 and the inner frame body 2, and then the volume of the fence box is adjusted.

[0049] It is apparent for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, but can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be considered in all aspects as illustrative and not restrictive, and the scope of the present application is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and range of the equivalent elements of the claims are intended to be embraced in the present application.
