Description

Technical Field

[0001] This utility model relates to the field of packaging technology, and in particular to a cushioning and anti-collision corner protector and corner protector assembly for a box. Background Technology

[0002] Flight cases and other containers used for packaging and transportation are highly susceptible to damage to their corners during logistics handling due to collisions, squeezing, friction, or impacts from drops. Therefore, corner protectors are crucial for protecting the container structure and extending its service life. Currently, corner protectors are widely made from a single material, such as stamped or die-casted sheet metal corner protectors commonly found on the market. These corner protectors, thanks to the high strength of metal, effectively resist external impacts and provide rigid protection for the container.

[0003] However, corner protectors made of a single metal material are hard and lack elastic deformation space, making them unable to absorb the kinetic energy generated by collisions. During transportation, severe collisions and vibrations will not only exacerbate the stress concentration at the connection between the corner protector and the box, causing the corner protector to loosen, deform, or even fall off, but may also cause irreversible damage to the items inside the box. At the same time, continuous vibration and impact will also accelerate the fatigue of the box material and shorten its overall service life.

[0004] In addition, existing corner protectors can only be used to splice and stack boxes on specific surfaces, such as the top and bottom, which limits their applicability. Utility Model Content

[0005] In order to overcome at least one of the defects of the prior art, one of the objectives of this utility model is to provide a cushioning and anti-collision corner protector for a box, which is provided with a cushioning seat to reduce the direct impact of vibration on the box or the items inside the box, and reduce the possibility of irreversible damage to the items caused by collision and vibration.

[0006] The second objective of this utility model is to provide a corner protector assembly, which includes two sets of buffer and anti-collision box corner protectors. The buffer seats on the two corner protectors are in concave-convex fit, which facilitates stacking and has a wide range of applications.

[0007] One of the objectives of this utility model is achieved through the following technical solution:

[0008] A cushioning and anti-collision box corner protector includes: a corner protector base and a buffer base. The corner protector base includes a corner protector body and at least two corner protector pieces. The corner protector pieces are connected to the corner protector body and extend out of the corner protector body. The at least two corner protector pieces are spaced apart on the corner protector body and enclose the corner protector body to form a corner protector space. The corner protector body is provided with a first connecting part, and the buffer base is provided with a second connecting part. The second connecting part is detachably connected to the first connecting part.

[0009] The first connecting portion includes a first mounting hole; the second connecting portion includes a second mounting hole; the first mounting hole and the second mounting hole are used for connecting the connector.

[0010] Furthermore, the first connecting portion includes a first snap-fit ​​portion, and the second connecting portion includes a second snap-fit ​​portion, the second snap-fit ​​portion engaging with the first snap-fit ​​portion.

[0011] Furthermore, the outer peripheral wall of the buffer seat is an arc surface.

[0012] Furthermore, the corner protector is provided in three parts, and the three corner protectors are connected to each other in the circumferential direction of the corner protector body; and two adjacent corner protectors are connected perpendicularly.

[0013] Furthermore, each corner piece has a mounting groove and a through hole at its end away from the corner body. The through hole is located in the mounting groove and is used to connect to a connector.

[0014] Furthermore, the buffer seat has a first abutting surface and a second abutting surface. The first abutting surface is provided with a protrusion, and the second abutting surface is provided with a recess. The recess and the protrusion are in a concave-convex fit.

[0015] The technical solution adopted for the second objective of this utility model is:

[0016] A corner protector assembly includes the aforementioned buffer and anti-collision box corner protector. The buffer and anti-collision box corner protector is provided in two sets. The two sets of buffer and anti-collision box corner protectors include a first corner protector and a second corner protector. The first corner protector includes a first corner protector base and a first buffer base. The second corner protector includes a second corner protector base and a second buffer base. The first corner protector base and the second corner protector base have the same structure.

[0017] The first buffer seat has a protrusion and two recesses, and the protrusion and the two recesses are distributed at intervals along the circumference of the first buffer seat.

[0018] The second buffer seat has two protrusions and one recess, with the two protrusions and the one recess being spaced apart in the circumferential direction of the second buffer seat;

[0019] The recessed portion on the first buffer seat and the protruding portion on the second buffer seat are in a recessed-protruding fit; the recessed portion on the second buffer seat and the protruding portion on the first buffer seat are in a recessed-protruding fit.

[0020] Furthermore, the first buffer seat is provided with three second connecting parts, and the protrusion on the first buffer seat is provided with a mounting recess, one of the second connecting parts being located in the mounting recess; the other two second connecting parts are respectively installed in the two recesses.

[0021] The second buffer seat is provided with three second connecting parts. Each of the two protrusions on the second buffer seat is provided with a mounting recess, wherein two of the second connecting parts are located in the mounting recess and the other second connecting part is located in the recess.

[0022] Furthermore, both the recessed portion of the first buffer seat and the protruding portion of the second buffer seat are provided with installation orientation markings.

[0023] In summary, the corner protector and corner protector assembly for a box provided by this utility model have the following technical effects: the corner protector body is connected to the box body through a corner space formed by at least two corner protector pieces, and then a buffer seat is installed on the outer periphery of the corner protector body to provide buffering force, reducing the direct impact of vibration on the box body or the items inside the box during transportation, reducing the possibility of irreversible damage to the items due to collision and vibration, and indirectly extending their service life. At the same time, it reduces the risk of the corner protector seat becoming loose due to impact.

[0024] Furthermore, when in use, the corner protector assembly features a reciprocating fit between the recessed portion on the first buffer seat and the protruding portion on the second buffer seat, and vice versa. This allows the boxes to fit snugly together when stacked, reducing the direct impact of vibrations on the box or its contents during transport. It also facilitates the stacking of multiple boxes, offering high flexibility and a wide range of applications. Attached Figure Description

[0042] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0043] Example 1,

[0044] See Figures 1 to 4 This utility model discloses a corner protector for a buffer and anti-collision housing 30, including: a corner protector base 10 and a buffer base 20. The corner protector base 10 includes a corner protector body 11 and at least two corner protector pieces 12. The corner protector pieces 12 are connected to the corner protector body 11 and extend out of the corner protector body 11. At least two corner protector pieces 12 are spaced apart on the corner protector body 11 and enclose the corner protector body 11 to form a corner protector space 13. The corner protector body 11 is provided with a first connecting part 111, and the buffer base 20 is provided with a second connecting part 21. The second connecting part 21 is detachably connected to the first connecting part 111.

[0045] Based on the above structure, during assembly, at least two corner protectors 12 are spaced apart along the periphery of the corner protector body 11, so that the at least two corner protectors 12 enclose a corner protector space 13, which covers the external structure (such as a box or a table corner with sharp corners).

[0046] Meanwhile, since the buffer seat 20 is connected to the corner protector body 11, the corner protector piece 12 can absorb the kinetic energy generated by external collisions, compressions or drops through its own elastic deformation after being connected to the external structure. This reduces the direct transmission of impact forces such as collisions or vibrations to the external structure or the corner protector body 11 during transportation, reduces the risk of structural damage, reduces fatigue damage to the corner protector 10 or the external structure caused by hard collisions, and extends the overall service life of the corner protector body 11 and the protected object.

[0047] In addition, since the buffer seat 20 is detachably connected to the corner protector body 11, when the buffer seat 20 is worn, aged or damaged due to long-term use, it can be disassembled and replaced separately without having to scrap the entire corner protector, thus reducing maintenance costs.

[0048] In addition, the buffer seat 20 can be quickly replaced with different materials (such as rubber, sponge, spring structure, etc.) or performance according to different transportation or usage scenarios (such as high frequency vibration, high intensity impact), flexibly adjusting the buffering force and protection effect, making it more flexible to use and more applicable.

[0049] It should be noted that the corner bracket 10 in this embodiment can be made of metal materials, such as iron plate, aluminum plate, stainless steel, cast aluminum, cast iron, alloy, etc., while the buffer seat 20 can be made of existing materials with cushioning properties such as polyurethane PU, TPU (thermoplastic polyurethane elastomer), silicone, rubber, soft plastic, etc., so that the metal corner bracket 10 can provide high-strength structural support, while the elastic buffer seat 20 can cover the corner bracket 10 to provide protection and cushioning.

[0050] More specifically, in this embodiment, the first connecting part 111 on the corner protector 11 can be a buckle or a buckle block, while the second connecting part 21 is a slot or a notch provided on the buffer seat 20 that is compatible with the buckle or buckle block, so that the two can be engaged and connected to achieve detachability.

[0051] Of course, the first connecting part 111 can also be a threaded hole or a pin hole provided on the corner body 11, and the second connecting part 21 can be a corresponding threaded hole or a pin hole. By connecting screws, bolts or pins through the first connecting part 111 and the second connecting part 21, a detachable connection can also be achieved.

[0052] In addition, the first connecting part 111 and the second connecting part 21 can also be adhesive strips respectively provided on the corner protector 11 and the buffer seat 20. The two are bonded together by the two adhesive strips to achieve the connection between them. When replacement is needed, the two adhesive strips can be peeled off, which can also achieve a detachable connection.

[0053] Example 2,

[0054] See Figures 1-4 In this embodiment, the corner protector 11 is provided with a first mounting hole, which is formed as a first connecting part 111. The buffer seat 20 is provided with a second mounting hole, which is formed as a second connecting part 21. The first mounting hole and the second mounting hole are used to connect the connecting parts.

[0055] Specifically, in this embodiment, the first mounting hole and the second mounting hole can be threaded holes, and the connector can be an existing screw or bolt structure. During assembly, the connector is passed through the second mounting hole and the first mounting hole in sequence and tightened so that the buffer seat 20 is connected to the corner body 11.

[0056] Of course, the first mounting hole and the second mounting hole are threaded holes, such as pin holes. In this case, the connecting parts are selected as pins or screws, which can also lock the buffer seat 20 and the corner body 11.

[0057] Example 3,

[0058] In this embodiment, the corner protector 11 is provided with a first snap-fit ​​part, which is formed as a first connecting part 111. The buffer seat 20 is provided with a second snap-fit ​​part, which is formed as a second connecting part 21. The second snap-fit ​​part is engaged and connected with the first snap-fit ​​part.

[0059] Specifically, the first snap-fit ​​part can be a buckle set on the corner protector body 11, while the second snap-fit ​​part is a latch set on the buffer seat 20. The latch matches the buckle so that the buffer seat 20 and the corner protector body 11 can be snapped together and connected to achieve detachability.

[0060] Of course, the first locking part can also be set in the locking slot on the corner body 11, and the second locking part can be set in the locking block on the buffer seat 20. The two can be locked together to achieve the same effect.

[0061] Example 4,

[0062] See Figures 1-4 Furthermore, based on Embodiment 1, the outer peripheral wall of the buffer seat 20 is an arc surface.

[0063] Specifically, by setting an arc surface on the buffer seat 20, the external impact force (such as loading and unloading collision, drop impact) is evenly distributed to the entire buffer seat 20 through the arc surface structure, so as to avoid stress concentration at a single point or edge.

[0064] Compared to planar structures where force is concentrated at the point of contact when impacted, easily leading to local deformation or breakage, curved surfaces guide force to the surrounding areas through the normal direction of the curved surface, reducing the pressure per unit area and thus improving the impact resistance of the buffer seat 20.

[0065] It should be noted that the buffer seat in this embodiment can be formed by a seat body with an outer surface that connects an arc surface and a flat surface, so that its surface is formed with an arc surface and a flat surface, so that the flat surface abuts against the corner seat and the external structure, while the arc surface buffers the pressure.

[0066] Furthermore, there are three corner pieces 12, which are connected to each other in the circumferential direction of the corner body 11; and two adjacent corner pieces 12 are connected perpendicularly.

[0067] Specifically, in this embodiment, the three corner protectors 12 are vertically connected to form a three-dimensional structure of a "right-angled triangular prism", which can tightly wrap the right-angled corners of the box 30 (such as the top corner of a cuboid) and achieve full coverage protection of the intersection of the three adjacent surfaces of the box 30.

[0068] More specifically, after the three corner pieces 12 are connected perpendicularly to each other, they form a triangular structure in the plane projection, which utilizes the geometric stability principle of triangles to improve the overall deformation resistance of the corner bracket 10.

[0069] Furthermore, each corner piece 12 is provided with a mounting groove 121 and a through hole 122 at the end away from the corner body 11. The through hole 122 is located in the mounting groove 121 and is used to connect the connector.

[0070] Specifically, when the corner bracket 12 is connected to the external structure, the through hole 122 can be aligned with the through hole 122 on the external structure, and the connector (such as a screw or bolt) can be inserted into the external structure through the through hole 122 to make the corner bracket 10 stably connected to the external structure.

[0071] Furthermore, since the through hole 122 is located within the mounting groove 121, when a connector (such as a screw or bolt) passes through the through hole 122, the head of the connector can be recessed into the mounting groove 121, avoiding any exposed protrusion and resulting in a cleaner appearance.

[0072] Furthermore, the buffer seat 20 has a first abutting surface 22 and a second abutting surface 23. The first abutting surface 22 is provided with a protrusion 221, and the second abutting surface 23 is provided with a recess 231. The recess 231 and the protrusion 221 are in a concave-convex fit.

[0073] Specifically, when multiple boxes 30 are equipped with multiple corner protectors and need to be stacked, the first abutting surface 22 on the buffer seat 20 of the corner protector can be fitted with the second abutting surface 23 on the buffer seat 20 of another adjacent box 30. Since the protrusion 221 on the first abutting surface 22 and the protrusion 221 on the second abutting surface 23 are in concave-convex fit, the two protrusions 221 of the buffer seats 20 on the two adjacent boxes 30 can be embedded into the recess 231, so that the boxes 30 are tightly fitted, and the stacked boxes are more stable, reducing the risk of shaking due to external force collision.

[0074] Example 5,

[0075] like Figures 5-9As shown, a corner protector assembly includes the buffer and anti-collision box body 30 corner protectors as described in Embodiments 1 to 4. Two sets of buffer and anti-collision box body 30 corner protectors are provided, each set including a first corner protector and a second corner protector. The first corner protector includes a first corner protector seat 10 and a first buffer seat 20', and the second corner protector includes a second corner protector seat 10 and a second buffer seat 20'. The first corner protector seat 10 and the second corner protector seat 10 have the same structure. The first buffer seat 20' has a protrusion 221 and two recesses. Part 231, the protrusion 221 and the two recesses 231 are distributed circumferentially at intervals along the first buffer seat 20'; the second buffer seat 20" has two protrusions 221 and one recess 231, the two protrusions 221 and the one recess 231 are distributed circumferentially at intervals along the second buffer seat 20"; the recesses 231 on the first buffer seat 20' and the protrusions 221 on the second buffer seat 20" are in concave-convex fit; the recesses 231 on the second buffer seat 20" and the protrusions 221 on the first buffer seat 20' are in concave-convex fit.

[0076] Based on the above structure, when the boxes 30 are stacked, the two sides of the two boxes 30 that are in contact with each other, such as the two sides facing each other vertically, the two sides facing each other horizontally, or the two sides facing each other front and back, are respectively provided with a first corner protector and a second corner protector. The protrusion 221 on the first buffer seat 20' of the first corner protector is positioned towards the recess 231 on the second buffer seat 20" of the second corner protector, so that the protrusion 221 on the first buffer seat 20' is embedded in the recess 231 on the second buffer seat 20" and the two adjacent boxes 30 are stably attached and the stacking is more stable.

[0077] To ensure efficient stacking and reduce installation errors, the following methods can be used during installation:

[0078] Method 1: (a) First corner protectors are installed on the top corners 31 of the box body 30. The recessed portion 231 of the first buffer seat 20' of the first corner protector is vertically upward. Looking directly at the vertically upward recessed portion 231, a protrusion 221 and a recessed portion 231 are arranged in sequence along the clockwise direction of the vertically upward recessed portion 231, or a recessed portion 231 and a protrusion 221 are arranged in sequence along the clockwise direction of the vertically upward recessed portion 231; (b) Second corner protectors are installed on the bottom corners 32 of the box body 30. The protrusion 221 of the second buffer seat 20' of the second corner protector is vertically downward. Looking directly at the vertically downward protrusion 221, a protrusion 221 and a recessed portion 231 are arranged in sequence along the clockwise direction of the vertically downward protrusion 221, or a recessed portion 231 and a protrusion 221 are arranged in sequence along the clockwise direction of the vertically downward protrusion 221.

[0079] Method 2: (a) First corner protectors are installed on the bottom corners 32 of the box body 30. The recessed portion 231 of the first buffer seat 20' of the first corner protector is vertically downward. Looking directly at the vertically upward recessed portion 231, a protrusion 221 and a recessed portion 231 are arranged in sequence along the clockwise direction of the vertically downward recessed portion 231, or a recessed portion 231 and a protrusion 221 are arranged in sequence along the clockwise direction of the vertically upward recessed portion 231; (b) Second corner protectors are installed on the top corners 31 of the box body 30. The protrusion 221 of the second buffer seat 20' of the second corner protector is vertically upward. Looking directly at the vertically upward protrusion 221, a protrusion 221 and a recessed portion 231 are arranged in sequence along the clockwise direction of the vertically upward protrusion 221, or a recessed portion 231 and a protrusion 221 are arranged in sequence along the clockwise direction of the vertically upward protrusion 221.

[0080] Method 3: A specific installation orientation mark is made on the recessed portion 231 of the first corner protector, and a specific mark is made on the protruding portion 221 of the second corner protector. For example, the recessed portion 231 of the first corner protector is marked "Up," and the protruding portion 221 of the second corner protector is marked "Down." In this case, all the first corner protectors are installed at the top corner 31 of the housing 30, with the recessed portion 231 marked "Up" facing vertically upwards. All the second corner protectors are installed at the bottom corner 32 of the housing 30, with the protruding portion 221 marked "Down" facing vertically downwards. Method 3 pre-sets the installation direction at the factory, facilitating direct installation by workers without requiring directional identification.

[0081] Specifically, when the boxes are stacked, the vertically upward-facing protrusion 221 serves as the load-bearing point of the upper box 30. When the protrusion 221 is vertically upward, it can vertically transmit the weight of the upper box 30 to the recess 231 of the lower box 30 through its own rigid structure (such as a metal frame or high-strength plastic), forming an axial compression state and preventing stress concentration at the edge of the corner piece. Furthermore, when the protrusion 221 is inserted into the recess 231 of the lower box 30, it can form a reverse support to resist horizontal thrust and improve the anti-slip capability of the bottom box 30.

[0082] As the supporting structure for the lower box 30, the recessed portion 231, when vertically downward, can accommodate the protruding portion 221 of the upper box 30, forming a nested relationship of "recess containing protrusion". Furthermore, the elastic cushioning material (such as rubber) of the recessed portion 231 can absorb vertical impact forces through radial deformation, while simultaneously restricting the lateral movement of the protruding portion 221, achieving a dual effect of "rigid positioning plus flexible cushioning". This makes the stacked boxes 30 more stable.

[0083] Furthermore, by setting up the first buffer seat 20' and the second buffer seat 20", the kinetic energy generated by external collisions, compression, or drops can be absorbed by the elastic deformation of the two buffer seats 20 themselves, reducing the probability of the box 30 shaking due to impacts or vibrations after being stacked during transportation. At the same time, it can also reduce the direct transmission of external impacts to the inside of the box 30 or the corner protector 11, reducing the risk of damage to items inside or outside the box 30 or to the corner protector, and extending the overall service life of the corner protector 10 and the protected object.

[0084] In addition, since the buffer seat 20 is detachably connected to the corner protector body 11, when the buffer seat 20 is worn, aged or damaged due to long-term use, it can be disassembled and replaced separately without having to scrap the entire corner protector, thus reducing maintenance costs.

[0085] Furthermore, the first buffer seat 20' is provided with three second connecting parts 21, and the protrusion 221 on the first buffer seat 20' is provided with a mounting recess 2211, one of the second connecting parts 21 is located in the mounting recess 2211; the other two second connecting parts 21 are respectively installed in two recesses 231.

[0086] Specifically, in this embodiment, three second connecting parts 21 are provided on the first buffer seat 20' so that the three second connecting parts 21 can be connected to the first corner seat 10 from different angles, making the connection between the two more stable.

[0087] Meanwhile, since the protrusion 221 is provided with a mounting recess 2211, and one of the second connecting parts 21 is installed in the mounting recess 2211, while the other two second connecting parts 21 are respectively located in the two recesses 231 on the first buffer seat 20', when the second connecting part 21 is connected to the first corner bracket 10, the second connecting part 21 can be hidden in the mounting recess 2211 and the recesses 231, thus preventing the second connecting part 21 from protruding from the surface of the first buffer seat 20' and affecting the stacking of the box 30.

[0088] Similarly, the second buffer seat 20” is provided with three second connecting parts 21. By providing three second connecting parts 21 on the second buffer seat 20”, the two parts can be connected to the second corner bracket 10 from different angles, making the connection between the two more stable. At the same time, the two protrusions 221 on the second buffer seat 20” are provided with mounting recesses 2211. Two of the second connecting parts 21 are located in the mounting recesses 2211, and the other second connecting part 21 is located in the recess 231. So when the second connecting part 21 is connected to the second corner bracket 10, the second connecting part 21 can be hidden in the mounting recesses 2211 and the recess 231, preventing the second connecting part 21 from protruding from the surface of the first buffer seat 20’ and affecting the stacking of the box 30.

[0089] More specifically, to prevent users from misaligning the installation directions of the first and second corner brackets during installation, this embodiment provides installation orientation markings (such as...) in both the recessed portion 231 of the first buffer seat 20' and the protruding portion 221 of the second buffer seat 20'". Figures 7 to 8 As shown in the figure, the installation orientation marks help users identify the installation direction during assembly, eliminating the need for repeated trial and error. Users can directly align the direction according to the installation orientation marks, thus shortening the installation time.
