Referring to fig. 1 to 4, the present embodiment provides a corner piece for a combined tray, including a corner body 100, where the corner body 100 is a block-shaped structure, and the corner body 100 is made of plastic;

in the present embodiment, the corner body 100 is configured with two adjacent and mutually perpendicular first contact surfaces 101 and second contact surfaces 102, as shown in fig. 1 and 2, the first contact surfaces 101 and the second contact surfaces 102 are two adjacent side surfaces of the corner body 100, so as to be in positive contact with the adjacent edge strips 400 or corner pieces at the corners and be spliced together, so as to fill up the gaps formed at the rear corners of the adjacent two side mounting edge strips 400 of the tray, so that the whole combined tray can be formed into a regular rectangular structure, as shown in fig. 4;

in order to fit the main board 300 (i.e. a tray or a tray body, which will not be described in detail later) and the edge strip 400 (or called an extension strip, the edge strip 400 may be mounted on one side of the main board 300, so as to achieve the purpose of widening and collision avoidance, which will not be described in detail later), the corner body 100 is further configured with a first bearing surface 103 and a second bearing surface 104, wherein the first bearing surface 103 and the second bearing surface 104 are parallel to each other and perpendicular to the first contact surface 101 and the second contact surface 102, as shown in fig. 1 to 3, the first bearing surface 103 is disposed at the top of the first contact surface 101 and the second contact surface 102, the second bearing surface 104 is disposed at the bottom of the first contact surface 101 and the second contact surface 102, and the distance between the first bearing surface 103 and the second bearing surface 104 is adapted to the height of the main board 300 or the height of the edge strip 400, so that after the assembly is completed, the first bearing surface 103 may be flush with the upper surface of the main board 300 or the upper surface of the edge strip 400, the second bearing surface 104 may be flush with the lower surface of the main plate 300 or the lower surface of the edge strip 400.

In addition, the corner body 100 is further configured with an outer side surface connected to the first contact surface 101, the second contact surface 102, the first bearing surface 103, and the second bearing surface 104, respectively, so that the first contact surface 101, the second contact surface 102, the first bearing surface 103, the second bearing surface 104, and the outer side surface may jointly enclose the corner body 100, and in a specific implementation, the outer side surface may be a surface, for example, an arc surface, so as to form an arc corner; the outer side surface may also be formed by a plurality of surfaces, for example, in a preferred embodiment, the corner body 100 is further configured with a first outer side 105 and a second outer side 106, the first outer side 105 corresponding to the first contact surface 101, and is parallel to the first contact surface 101, said second outer side 106 corresponds to said second contact surface 102, and parallel to the second contact surface 102, as shown in fig. 1-4, such that the first contact surface 101, the second contact surface 102, the first bearing surface 103, the second bearing surface 104, the first outer side 105, and the second outer side 106 may collectively enclose a corner body 100, it being understood that, in practical implementation, two adjacent surfaces can be directly connected with each other, so that the whole corner body 100 can form a standard rectangular parallelepiped structure, as shown in fig. 1, the corner bodies 100 may be connected by a chamfer or a fillet so as to form a rectangular parallelepiped-like structure.

In practical implementation, the size of the corner body 100 may be determined according to practical requirements, for example, in the corner body 100, the distance between the first carrying surface 103 and the second carrying surface 104 is generally required to be adapted to the height of the main plate 300 or the edge strip 400, and since the height of the main plate 300 and the height of the edge strip 400 are both 150mm in the prior art, in a preferred embodiment, the distance between the first carrying surface 103 and the second carrying surface 104 may be 150 mm.

In corner body 100, the distance between first outer side 105 and first contact surface 101 should match the width of edge strip 400, where the matching means that the distance between first outer side 105 and first contact surface 101 is equal to the width of edge strip 400, or the distance between first outer side 105 and first contact surface 101 is an integer multiple, such as one, two, three, etc., of the width of edge strip 400, or the width of edge strip 400 is an integer multiple of the distance between first outer side 105 and first contact surface 101, for example, in a preferred embodiment, the distance between first outer side 105 and first contact surface 101 may be 50mm, 100mm, or 200mm, and accordingly, the width of edge strip 400 may also be 50mm, 100mm, or 200 mm; the matching mode between the corner body 100 and the edge strip 400 is more flexible, so that the requirements of different size combination trays can be met at low cost.

Likewise, in the corner body 100, the distance between the second outer side 106 and the second contact surface 102 should also match the width of the edge strip 400, where the matching is that the distance between the second outer side 106 and the second contact surface 102 is equal to the width of the edge strip 400, or the distance between the second outer side 106 and the second contact surface 102 is an integer multiple of the width of the edge strip 400, or the width of the edge strip 400 is an integer multiple of the distance between the second outer side 106 and the second contact surface 102, for example, in a preferred embodiment, the distance between the second outer side 106 and the second contact surface 102 may be 50mm, 100mm, or 200mm, and correspondingly, the width of the edge strip 400 may also be 50mm, 100mm, or 200 mm; so that the fitting manner between the corner body 100 and the edge strip 400 is more flexible and the cost is low.

The strake 400 and the corner piece with corresponding sizes are produced by using the least number of moulds, and the strake 400 and the corner piece with different numbers and different widths are assembled on the main board 300, so that combined trays with different sizes can be realized (at least more than 500 combined trays with different sizes can be obtained), the universality can be improved, and the cost can be obviously reduced.

As shown in fig. 1 to 3, in the corner fitting, a first plug 201 and a second plug 202 protruding outward are respectively configured in the first contact surface 101 and the second contact surface 102, and the first plug 201, the second plug 202 and the corner body 100 are integrally formed members, for example, the corner body 100, the first plug 201 and the second plug 202 may be injection molded; the first plug connector 201 and the second plug connector 202 are respectively constructed on the first contact surface 101 and the second contact surface 102 which are perpendicular to each other, the plug cavities of the adjacent edge strips 400 or corner pieces can be constructed in a matched mode, the mounting and fixing of the corner pieces are facilitated, the first plug connector 201 and the second plug connector 202 are integrally formed with the corner body 100, screws are not needed to be used for connection, the structure of the corner pieces is simplified, the cost is reduced, and the assembly is facilitated.

As shown in fig. 1-3, the first plug 201 is further configured with a locking hole 203, and similarly, the second plug 202 is also configured with a locking hole 203, so that when being assembled, the fastener 500 can transversely pass through the locking hole 203, thereby achieving the purpose of transversely locking the corner fitting.

In specific implementation, the locking hole 203 may be a circular hole, and the circular hole may be adapted to a fastening member 500 having a circular structure, such as the fastening member 500 disclosed in chinese patent, and in a preferred embodiment, the locking hole 203 may be a square hole, as shown in fig. 1 to 4, which may be adapted to the fastening member 500 having a square structure, and when the corner member is connected to the edge strip 400 or the main plate 300 through the fastening member 500 having a square structure, as shown in fig. 4, the problem that the fastening member 500 cannot be smoothly inserted due to a dimensional error of the edge strip 400 and/or the main plate 300 may be solved.

In this embodiment, the first plug 201 and the second plug 202 only play a role of connection, and only need to be adapted to the corresponding plugging cavities, and there is no need to limit the shapes of the first plug 201 and the second plug 202, but in order to simplify the structure, in a preferred embodiment, the first plug 201 may preferentially adopt a sheet structure, as shown in fig. 1 to 3, and correspondingly, the second plug 202 may preferentially adopt a sheet structure, which is not only convenient for molding, but also convenient for inserting into the corresponding plugging cavities; for assembly, the first plug 201 may be perpendicular to the first contact surface 101, and similarly, the second plug 202 may be perpendicular to the second contact surface 102, as shown in fig. 2.

It can be understood that, in order to make the locking hole 203 meet the requirement of matching with the plugging cavity, a certain distance (distance) should be provided between the locking hole 203 and the corresponding first contact surface 101 or second contact surface 102, and in order to facilitate the integral molding, in a further aspect, at least a portion between the locking hole 203 and the first contact surface 101 in the first plugging head 201 is configured with a plurality of process grooves 204 or process holes, as shown in fig. 1 and 2, so that not only the portion between the locking hole 203 and the first contact surface 101 can be smoothly injection molded, but also the material can be saved, accordingly, at least a portion between the locking hole 203 and the second contact surface 102 in the second plugging head 202 is configured with a plurality of process grooves 204 or process holes, as shown in fig. 1 and 2, so as to achieve the technical effect of large communication.

When the process tank 204 is adopted, in order to prevent the problem of water accumulation in the process tank 204 during use, a drain hole 205 is further formed in the bottom of the process tank 204, as shown in fig. 1 and 2, so that water in the process tank 204 can be drained automatically, and the problems of water accumulation, mildew and the like in the process tank 204 can be avoided.

In practical implementation, in order to facilitate the installation of the fastener 500 from the first bearing surface 103 and the second bearing surface 104, the first plug connector 201 and the second plug connector 202 should be configured at positions close to the first bearing surface 103 or the second bearing surface 104, respectively, so that in a preferred embodiment, two sets of first plug connectors 201 are configured at the upper portion and the lower portion of the first contact surface 101, each set of first plug connectors 201 includes at least one first plug connector 201, when each set of first plug connectors 201 includes at least two first plug connectors 201, the first plug connectors 201 in each set are configured at the same height, respectively, as shown in fig. 1 and 3, similarly, two sets of second plug connectors 202 are configured at the upper portion and the lower portion of the second contact surface 102, each set of second plug connectors 202 includes at least one second plug connector 202, when each set of second plug connectors 202 includes at least two second plug connectors 202, the second connectors 202 in each group are respectively configured at the same height, as shown in fig. 1 and 3; in the corner fitting, the number of the first connectors 201 in each group of the first connectors 201 and the number of the second connectors 202 in each group of the second connectors 202 may be determined according to actual requirements, for example, according to the size of the corner body 100, the number of the first connectors 201 and the number of the second connectors 202 in each group may be one, two, or more, respectively, for a corner body 100 with a smaller volume (for example, 50mm × 50mm (the former 50mm refers to a distance between the first outer side 105 and the first contact surface 101 being 50mm, the latter 50mm refers to a distance between the second outer side 106 and the second contact surface 102 being 50mm, which is not described herein again), 100mm × 50mm, 50mm × 100mm, 100mm × 100mm, and the like), in a preferred embodiment, as shown in fig. 1 to 6, the first contact surface 101 is configured with two groups of the first connectors 201, and each set of first plug connectors 201 includes a first plug connector 201, and the two first plug connectors 201 are respectively located at the upper portion and the lower portion of the first contact surface 101, that is, the two first plug connectors 201 have a set distance along the vertical direction, as shown in fig. 1-6, similarly, two sets of second plug connectors 202 may also be configured in the second contact surface 102, and each set of second plug connectors 202 includes a second plug connector 202, and the two second plug connectors 202 are respectively located at the upper portion and the lower portion of the second contact surface 102, so that the same edge strip 400 is connected together by using the two first plug connectors 201 or the two second plug connectors 202, which is not only beneficial to more firmly installing the corner piece, but also beneficial to configuring the plug cavities adapted thereto at positions close to the upper surface and the lower surface of the main board 300 or the upper surface and the lower surface of the edge strip 400, thereby being more convenient to install the fastener 500.

For the corner body 100 with a larger volume (for example, the corner body 100 with a size of 200mm × 200mm, etc.), in a preferred embodiment, as shown in fig. 7, two sets of first connectors 201 are configured in the first contact surface 101, each set of first connectors 201 includes two first connectors 201, and the two first connectors 201 in the same set are configured at the same height, respectively, so that the four first connectors 201 can be distributed in a rectangular shape as shown in fig. 7; similarly, two sets of second connectors 202 may be formed in the second contact surface 102, each set of second connectors 202 includes two second connectors 202, and the two second connectors 202 in the same set are formed at the same height, so that the four second connectors 202 may be distributed in a rectangular shape, as shown in fig. 7, so as to connect the same edge strip 400 with the four first connectors 201 or the four second connectors 202, which is not only beneficial to more firmly mounting the corner fitting.

In a more preferred embodiment, the first plug 201 and the second plug 202 may have the same structure, and the first plug 201 and the second plug 202 may be symmetrically disposed on two sides of the corner body 100, as shown in fig. 1 and 2, specifically, the first plug 201 and the second plug 202 may be symmetrically disposed along a middle plane between the first contact surface 101 and the second contact surface 102 (i.e., the middle plane is equal to a dihedral angle between the first contact surface 101 and the second contact surface 102), and since the first plug 201 and the second plug 202 have the same structure and are symmetrically disposed, the corner body may be applied to any corner of the tray, and when in use, a worker performing assembly may not need to distinguish a front side and a back side of the corner body, which may not only significantly improve the universality, but also simplify the assembly process and improve the assembly speed.

It can be understood that, in order to facilitate the injection molding of the corner body 100, the corner body 100 is further configured with a plurality of process grooves 204, as shown in fig. 1, fig. 3, and fig. 5 to fig. 7, the process grooves 204 may be configured on the first contact surface 101, the second contact surface 102, the first bearing surface 103, the second bearing surface 104, the first outer side surface 105, and/or the second outer side surface 106 to meet the requirement of the molding process, and will not be described herein again.

Example 2

In order to improve the bearing capacity of the corner fitting, the main difference between the present embodiment 2 and the above embodiment 1 is that in the corner fitting provided by the present embodiment, a channel 107 for installing a reinforcing member is further configured in the corner body 100, as shown in fig. 7, and the channel 107 at least penetrates through the first contact surface 101 or the second contact surface 102, so that when the corner fitting is assembled, the reinforcing member is inserted into the channel 107 to improve the bearing capacity of the corner fitting.

It will be appreciated that the reinforcing member may be a rectangular tube as is commonly used in the art, and accordingly, the channel 107 may preferably be a square channel 107 to fit the reinforcing member, but of course, the reinforcing member may also be a circular tube or the like, and the shape of the channel 107 may be adapted thereto.

The number of the channels 107 in the corner body 100 may be determined according to actual requirements, and specifically, the number of the channels 107 may be determined according to the size of the corner body 100, for example, according to the difference of the size of the volume, only one channel 107 may be configured in the corner body 100, and the channel 107 may vertically penetrate through the first contact surface 101 or the second contact surface 102; as another example, at least two mutually perpendicular channels 107 may be formed in the corner body 100, one channel 107 extending through at least the first contact surface 101, the other channel 107 extending through at least the second contact surface 102, and the two channels 107 may be formed near the upper and lower portions of the corner body 100, respectively, so that reinforcing members may be provided from two directions, respectively, to further improve the load-bearing capacity.

Furthermore, to improve the versatility, in a more preferred embodiment, two sets of channels 107 may be configured in the corner body 100, wherein one set of channels 107 is configured at the upper part of the corner body 100, and the set of channels 107 includes two channels 107 which are perpendicular to each other and communicate with each other, as shown in the figure; correspondingly, another set of channels 107 is configured at the lower part of the corner body 100, and the set of channels 107 includes two channels 107 which are perpendicular to each other and are communicated with each other, as shown in fig. 7 and 8, when actually assembling, each set of channels 107 can be provided with a reinforcing component, and the reinforcing component can be arranged in the channel 107 which is perpendicular to the first contact surface 101, and also can be arranged in the channel 107 which is perpendicular to the second contact surface 102, so that the use is facilitated to be more flexible, the main board 300 can be suitable for different corners, and the universality is better.

In order to facilitate assembly, in a further aspect, while one end of each channel 107 penetrates through the first contact surface 101 or the second contact surface 102, the other end of each channel 107 may penetrate through the first outer side 105 corresponding to the first contact surface 101 or the second outer side 106 corresponding to the second contact surface 102, as shown in fig. 7 and 8, that is, the channel 107 may completely penetrate through the entire corner body 100, thereby further facilitating installation of the reinforcing member during assembly; in addition, in a more perfect scheme, a first through hole 108 communicating with the channel 107 is further formed in the first bearing surface 103 and/or the first bearing surface 103, as shown in fig. 7, specifically, the channel 107 formed at the upper part of the corner body 100 may communicate with the first through hole 108 formed in the first bearing surface 103, and the channel 107 formed at the lower part of the corner body 100 may communicate with the first through hole 108 formed in the second bearing surface 104, so that a plug is installed at a position corresponding to the first through hole 108 in the channel 107, and a locking member such as a pin may be inserted through the first through hole 108, so as to laterally lock the plug, prevent the plug from falling off, and achieve the purpose of preventing the reinforcing member from falling off.

In a more sophisticated version, the corner body 100 is also configured with a second through hole communicating with said channel 107, said second through hole corresponding to said first through hole 108, for example, the second through hole may be coaxial with the first through hole 108, and the second through hole communicates with a process groove 204 configured in the corner body 100 so as to cooperate with the first through hole 108 and preferably lock the plug with a locking member.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention.
