Description

Technical Field

[0001] The utility model belongs to the technical field of packaging box sealing, and in particular relates to a combined packaging box. Background Art

[0002] Separable modular packaging boxes are a special type of large transport box, primarily used for transporting large cargo. Currently, these boxes typically use a flat-plate sealing structure at the assembly seam. When sealing requirements are high, the straightness of the sealing surface at the assembly seam is generally required to be no greater than 2-5 mm. If the straightness of the sealing surface at the assembly seam of a modular box is not properly controlled, it can easily exceed 2-5 mm, severely reducing the sealing performance or even causing the seal to fail, making it difficult for the modular box to protect against dust and water during transportation. Utility Model Content

[0003] Based on the above-mentioned problems existing in the prior art, the purpose of the embodiments of the present utility model is to provide a modular packaging box to solve the problem in the prior art that the straightness requirement of the sealing surface at the assembly seam of the modular packaging box is high, which increases the difficulty of controlling the straightness of the sealing surface at the assembly seam.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is to provide a combined packaging box, comprising:

[0005] first box;

[0006] a second box body, detachably assembled on the first box body to form a sealed packaging box; and

[0007] A sealing assembly is arranged at the assembly seam between the second box body and the first box body. The sealing assembly includes a first seal provided on the second box body and a second seal provided on the first box body. The first seal and the second seal include elastic members that can be compressed. The compression amount of the first seal is greater than the compression amount of the second seal. The second box body can press the first seal against the second seal to cause compression deformation of the first seal and the second seal.

[0008] Furthermore, the first sealing member includes a hollow elastic member with an O-shaped cross-section, and the second sealing member includes a flat elastic member.

[0009] Furthermore, the first sealing member is provided with an abutting protrusion, and the second sealing member is provided with an abutting surface. When the abutting protrusion presses against the abutting surface, the first sealing member and the second sealing member can be forced to generate compression deformation.

[0010] Furthermore, the sealing assembly also includes a pressure piece provided on the second box body and a first fixing piece provided on the pressure piece. The pressure piece and the first fixing piece are provided at the assembly seam between the second box body and the first box body. The first fixing piece is provided with a first card groove, and the first sealing piece is provided with a first clamping portion that is clamped with the first card groove.

[0011] Furthermore, the sealing assembly also includes a second fixing member provided on the first box body, the second fixing member is provided at the assembly seam between the first box body and the second box body, the second fixing member is provided with a second card groove, and the second sealing member is provided with a second clamping portion that is clamped with the second card groove.

[0012] Furthermore, the sealing assembly also includes a limiting structure arranged at the assembly seam between the second box body and the first box body, the limiting structure includes a third sealing member arranged on the second box body and a limiting member arranged on the first box body, and the limiting member can stop the third sealing member to limit the assembly seam spacing between the second box body and the first box body.

[0013] Furthermore, the third sealing member is a flat rubber strip.

[0014] Furthermore, the sealing assembly further includes a pressing member provided on the second box body and a limiting member provided on the first box body, wherein the pressing member and the limiting member are staggered to form staggered steps at the assembly seam between the second box body and the first box body.

[0015] Furthermore, the combined packaging box also includes a locking device capable of locking the second box body and the first box body, and the locking device includes a fixed seat provided on the second box body, a hinged seat provided on the first box body, a rotating shaft rotatably provided on the hinged seat, a connecting member connected to the rotating shaft, and a locking member capable of locking the connecting member to the fixed seat.

[0016] Furthermore, a locking groove is provided on the fixing seat, the connecting member is a connecting shaft that can be placed in or moved out of the locking groove, an external thread is provided on the end of the connecting shaft away from the hinged seat, and the locking member is an internal thread sleeve that can be screwed onto the external thread.

[0017] Compared with the prior art, the one or more technical solutions in the embodiments of the present invention have at least one of the following beneficial effects:

[0018] In the combined packaging box in the embodiment of the present invention, after the second box body is assembled on the first box body, the second box body is used to press the first seal against the second seal of the first box body. Since the compression amount of the first seal is greater than the compression amount of the second seal, the first seal produces a relatively large compression deformation, and the second seal produces a slight compression deformation. The second seal after the compression deformation can fill the assembly gap between the second box body and the first box body and play a sealing role. In this way, the straightness requirement of the sealing surface at the assembly seam between the second box body and the first box body can be reduced by the compression amount of the first seal and the second seal, thereby effectively reducing the difficulty of controlling the straightness of the sealing surface at the assembly seam between the second box body and the first box body, and at the same time it is beneficial to improve the assembly efficiency of the combined packaging box and enhance the sealing performance of the assembly seam of the combined packaging box.

[0032] Reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present application. Thus, when the phrases "in one embodiment," "in some embodiments," or "in some embodiments" appear in various places throughout this specification, not all references are to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0033] Please also refer to Figures 1 to 6 The modular packaging box provided by an embodiment of the present invention is now described. The modular packaging box provided by an embodiment of the present invention includes a first box body 1, a second box body 2, and a sealing assembly 3. The first box body 1 is a box structure with an open top, and the second box body 2 is a box structure with an open bottom. The dimensions of the first box body 1 and the second box body 2 are adapted so that the second box body 2 can be detachably assembled on the first box body 1 to form a sealed packaging box. The sealing assembly 3 is disposed at the assembly seam between the second box body 2 and the first box body 1. The sealing assembly 3 includes a first sealing member 31 disposed on the second box body 2 and a second sealing member 32 disposed on the first box body 1. The first sealing member 31 and the second sealing member 32 include compressible elastic members. The first sealing member 31 and the second sealing member 32 can be, but are not limited to, one of EPDM rubber, natural rubber, and butadiene rubber. In one specific application scenario, the thickness of the first sealing member 31 is greater than the thickness of the second sealing member 32, so that the compression amount of the first sealing member 31 is greater than the compression amount of the second sealing member 32. In another specific application scenario, the first seal 31 can be an elastic part made of rubber with a relatively large compression amount, and the second seal 32 can be an elastic part made of rubber with a relatively small compression amount, so that the compression amount of the first seal 31 is greater than the compression amount of the second seal 32. After the second box body 2 is assembled on the first box body 1 to realize the box assembly, the gravity of the second box body 2 is used to press the first seal 31 against the second seal 32 of the first box body 1. Since the compression of the first seal 31 is greater than the compression of the second seal 32, the first seal 31 produces a relatively large compression deformation, and the second seal 32 produces a slight compression deformation. After the compression deformation, the first seal 31 and the second seal 32 can fill the assembly gap between the second box body 2 and the first box body 1 and play a sealing role. In this way, the straightness requirement of the sealing surface at the assembly seam of the second box body 2 and the first box body 1 can be reduced by the compression of the first seal 31 and the second seal 32, thereby effectively reducing the difficulty of controlling the straightness of the sealing surface at the assembly seam of the second box body 2 and the first box body 1, and at the same time it is beneficial to improve the assembly efficiency of the combined packaging box and enhance the sealing of the assembly seam of the combined packaging box.

[0034] Please refer to Figure 1 、 Figure 3 and Figure 6 In some embodiments, the first sealing member 31 comprises a hollow elastic member with an O-shaped cross-section, and the second sealing member 32 comprises a flat elastic member, so that the compression amount of the first sealing member 31 is greater than the compression amount of the second sealing member 32. Furthermore, because the first sealing member 31 comprises a hollow elastic member with an O-shaped cross-section, when the second housing 2 presses the first sealing member 31 against the second sealing member 32 on the first housing 1, the first sealing member 31 can be compressed more, further facilitating lowering the straightness requirement of the sealing surface at the assembly seam between the second housing 2 and the first housing 1.

[0035] Please refer to Figure 6 In some embodiments, in order to further increase the compression of the first sealing member 31, while reducing the straightness requirements of the sealing surface at the assembly seam between the second box body 2 and the first box body 1, thereby further improving the sealing performance at the assembly seam of the modular packaging box, the first sealing member 31 is provided with an abutting protrusion 311 on the side facing the second sealing member 32, and the second sealing member 32 is provided with an abutting surface 321 for abutting the abutting protrusion 311. When the abutting protrusion 311 presses against the abutting surface 321, the first and second sealing members 31 and 32 are forced to produce compressive deformation. The abutting surface 321 can be a flat abutting surface, a convex abutting surface, or a concave abutting surface, and can be set according to actual sealing requirements.

[0036] Please refer to Figure 3 、 Figure 5 and Figure 6In some embodiments, the sealing assembly 3 further includes a pressing member 33 disposed on the second housing 2 and a first fixing member 34 disposed on the pressing member 33. The pressing member 33 and the first fixing member 34 are disposed at the assembly seam between the second housing 2 and the first housing 1. The first fixing member 34 is provided with a first engaging groove 35, and the first sealing member 31 is provided with a first engaging portion 312 that engages with the first engaging groove 35. In this embodiment, the first sealing member 31 can be removably assembled to the second housing 2 via the first fixing member 34 by simply engaging and fixing the first engaging portion 312 to the first engaging groove 35. This not only facilitates disassembly and maintenance of the first sealing member 31, but also enhances the stability of the first sealing member 31. In addition, a pressure member 33 is provided on the open end face of the second housing 2. This effectively ensures that the second housing 2 exerts a sufficiently strong pressure force on the first sealing member 31, causing the first sealing member 31 to undergo sufficient compression deformation, thereby enabling the first sealing member 31 to effectively fill the assembly gap between the second housing 2 and the first housing 1 and provide a seal. It should be noted that the first fixing member 34 may be a plastic member having a C-shaped or thin C-shaped cross-section. The plastic member may be, but is not limited to, polyvinyl chloride. The first fixing member 34 is secured to the pressure member 33 via fixing members such as rivets and is sealed using a sealant. The pressure member 33 is welded to the open end face of the second housing 2.

[0037] Please refer to Figure 1 、 Figure 5 and Figure 6 In some embodiments, the sealing assembly 3 further includes a second fixing member 36 disposed on the first housing 1. The second fixing member 36 is disposed at the assembly seam between the second housing 2 and the first housing 1. The second fixing member 36 is provided with a second latching groove 37, and the second sealing member 32 is provided with a second engaging portion 322 that engages with the second latching groove 37. In this embodiment, the second sealing member 32 can be removably assembled to the first housing 1 via the second fixing member 36 simply by engaging the second latching portion 322 with the second latching groove 37. This not only facilitates assembly and disassembly and maintenance of the second sealing member 32, but also enhances the stability of the second sealing member 32. It should be noted that the second fixing member 36 can be a plastic member with a C-shaped or thin C-shaped cross-section. The plastic member can be, but is not limited to, polyvinyl chloride. The second fixing member 36 is secured to the open end surface of the first housing 1 via a fixing member such as a rivet and is sealed using a sealant.

[0038] Please refer to Figure 1 、 Figure 3 and Figure 5In some embodiments, the sealing assembly 3 further includes a limiting structure 38 disposed at the assembly seam between the second box body 2 and the first box body 1. The limiting structure 38 includes a third sealing member 381 disposed on the second box body 2 and a limiting member 382 disposed on the first box body 1. After the second box body 2 is assembled on the first box body 1 to achieve box assembly, the limiting member 382 can stop the third sealing member 381, thereby limiting the assembly seam spacing between the second box body 2 and the first box body 1. On the one hand, this can prevent the second box body 2 from causing excessive compression deformation of the first sealing member 31 and fatigue damage. On the other hand, while the first sealing member 31 and the second sealing member 32 are in close contact and cooperation to achieve a primary seal, the third sealing member 381 and the limiting member 382 can be in close contact and cooperation to achieve a secondary seal, effectively enhancing the sealing performance of the assembly seam of the modular packaging box.

[0039] Please refer to Figure 3 and Figure 5 In some embodiments, the limiter 382 is a first ring beam provided on an open end face of the first box body 1, and the third sealing member 381 is a flat rubber strip that can fit tightly with the first ring beam. After the second box body 2 is assembled on the first box body 1 to realize the box assembly, the first ring beam stops the flat rubber strip to limit the assembly seam spacing between the second box body 2 and the first box body 1, and can realize secondary sealing of the assembly seam between the second box body 2 and the first box body 1.

[0040] Please refer to Figure 3 and Figure 5 In some embodiments, the sealing assembly 3 further includes a pressure member 33 provided on the second housing 2 and a limiting member 382 provided on the first housing 1. The pressure member 33 and the limiting member 382 are staggered to form a staggered step at the assembly seam between the second housing 2 and the first housing 1. This can, on the one hand, serve as a guide when assembling the second housing 2 on the first housing 1, and on the other hand, prevent the second housing 2 from being laterally displaced from the first housing 1. It should be noted that the limiting member 382 is a first ring beam provided on the end surface of the first housing 1 having an opening, and the pressure member 33 is a second ring beam provided on the end surface of the second housing 2 having an opening.

[0041] Please refer to Figure 1 、 Figure 4 and Figure 5In some embodiments, the modular packaging box further includes multiple locking devices 4 capable of locking the second box body 2 and the first box body 1. The multiple locking devices 4 are spaced apart at the connection between the second box body 2 and the first box body 1. The multiple locking devices 4 stably lock the second box body 2 to the first box body 1. At the same time, the locking devices 4 tighten the assembly seam between the second box body 2 and the first box body 1, further increasing the compression of the first sealing member 31 and the second sealing member 32, thereby improving the sealing performance of the assembly seam between the second box body 2 and the first box body 1. Each locking device 4 includes a fixed seat 41 provided on the second box body 2 and connected to the pressure member 33, a hinged seat 42 provided on the first box body 1, a rotating shaft 43 rotatably provided on the hinged seat 42, a connecting member 44 connected to the rotating shaft 43, and a locking member 45 capable of locking the connecting member 44 to the fixed seat 41. When the locking device 4 is in the locking mode, the connecting member 44 only needs to be rotated onto the fixing seat 41, and then the locking member 45 locks the connecting member 44 to the fixing seat 41, so that the second housing 2 can be stably locked to the first housing 1 through the locking device 4. When the locking device 4 is in the unlocking mode, the locking member 45 only needs to release the locking member 45 from the connecting member 44, and then rotate the connecting member 44 to separate the connecting member 44 from the fixing seat 41.

[0042] Please refer to Figure 4 In some embodiments, a locking groove 411 is provided on the fixing seat 41, and the connecting member 44 is a connecting shaft that can be placed in or removed from the locking groove 411. The end of the connecting shaft away from the hinge seat 42 is provided with an external thread, and the locking member 45 is an internal threaded sleeve that can be screwed onto the external thread. When operating the locking device 4 in the locking mode, it is only necessary to rotate the connecting shaft until the connecting shaft is rotated into the locking groove 411 on the fixing seat 41, and then tighten the internal threaded sleeve to lock the connecting shaft to the fixing seat 41. The second housing 2 can be stably locked to the first housing 1 through the locking device 4. When operating the locking device 4 in the unlocking mode, it is only necessary to loosen the internal threaded sleeve to release the locking of the connecting shaft by the internal threaded sleeve, and then rotate the connecting shaft to move the connecting shaft out of the locking groove 411 on the fixing seat 41.

[0043] Please refer to Figure 5In some embodiments, each locking device 4 further includes a limiting pad 46 provided between the internal threaded sleeve and the fixed seat 41, and the limiting pad 46 can be used to adjust the tightness of the locking device 4 between the first box body 1 and the second box body 2, so that the compression amount of the first seal 31 can be adaptively adjusted according to the actual sealing requirements. Each locking device 4 also includes a plurality of first bolts 47 for connecting the fixed seat 41 to the second ring beam on the second box body 2 and an adjusting pad 48 provided between the fixed seat 41 and the second ring beam, and the installation position of the fixed seat 41 can be adjusted by adjusting the pad 48. Each locking device 4 also includes a plurality of second bolts 49 for connecting the hinge seat 42 to the first box body 1 and an adjusting pad 48 provided between the hinge seat 42 and the first box body 1, and the installation position of the hinge seat 42 can be adjusted by adjusting the pad 48.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
