[0065] The first embodiment, refer to Figures 1 - 20 .

[0066] This embodiment provides a door splicing structure for a splicing cabinet. The door splicing structure includes a hinge assembly 3 and a latch assembly.

[0067] The hinge assembly 3 is used to connect the cabinet body 1 and the door 2. The door 2 is connected through the hinge assembly 3 and can rotate relative to the cabinet body 1, and the door 2 can be opened or closed. As Figures 1 - 4 , the hinge assembly 3 includes a first hinge member 31 and a second hinge member 32, and the first hinge member 31 and the second hinge member 32 are detachably and rotatably connected.

[0068] The first hinge member 31 includes a fixed end 311 and a first hinge end 312, and the second hinge member 32 includes an insertion end 321 and a second hinge end 322. The first hinge member 31 is fixed to the door 2 through the fixed end 311, and the second hinge member 32 is detachably connected to the cabinet body 1 through the insertion end 321. As Figure 4 , a hinge shaft 34 is provided at the first hinge end 312, and three convex rings 37 are arranged at intervals along the axis of the hinge shaft 34. The convex rings 37 protrude from the hinge shaft 34, and the diameter of the convex rings 37 is larger than the diameter of the hinge shaft 34. As Figure 3 , a hinge hole 33 is provided at the second hinge end 322. The inner diameter of the hinge hole 33 is adapted to the diameter of the hinge shaft 34. The second hinge end 322 includes a clearance 36 provided mainly to form a snap fit with the convex ring 37. The hinge hole 33 on the second hinge end 322 is divided into four holes at intervals of the clearance 36, and the holes and the clearance are arranged alternately.

[0069] The first hinge member 31 and the second hinge member 32 are detachably connected as follows: a relief notch 35 is provided corresponding to the hinge hole 33 on the second hinge end 322. The relief notch 35 is provided in the hinge hole 33 so that its transverse section forms a bayonet structure similar to a U-shaped opening. When the first hinge member 31 and the second hinge member 32 are snap-fitted, the clearance 36 and the convex ring 37 are made to correspond one by one, rotated until the relief notch 35 faces the hinge shaft 34, and the first hinge end 312 is pressed forcefully so that the hinge shaft 34 squeezes the relief notch 35 to deform and form a relief, so that the hinge shaft 34 is snapped into the hinge hole 33. After the snap fit, the first hinge member 31 and the second hinge member 32 can rotate under the cooperation of the hinge hole 33 and the hinge shaft 34. When it is necessary to disassemble the first hinge member 31 and the second hinge member 32, rotate the relief notch 35 to a suitable position, hold the first hinge member 31 and pull it outwards. The hinge shaft 34 squeezes the relief notch 35 to deform and form a relief, so that the hinge shaft 34 disengages from the hinge hole 33.

[0070] In this embodiment, the convex ring 37 is clamped in the clearance 36. One is to form a positioning installation, and the other is to limit the vertical movement of the first hinge member 31 and the second hinge member 32 to ensure smooth rotation.

[0071] Compared with the prior art, the hinge assembly 3 of this embodiment is optimized as follows: the first hinge 31 and the second hinge 32 of the prior art hinge assembly 3 need to be inserted from top to bottom into the shaft holes of the two through the shaft to form a rotatable installation. This assembly method has many parts and the insertion or extraction of the shaft requires the cooperation of auxiliary tools. The hinge assembly 3 provided in this embodiment only has the first hinge 31 and the second hinge 32. Compared with the prior art hinge assembly 3, it reduces scattered parts such as the shaft, and during installation, it only needs to align the clearance notch 35 with the hinge shaft 34, and the assembly can be completed with one button press. In addition, the second hinge 32 of this embodiment chooses to set the hinge shaft 34 as an integral part, which can avoid the scattered loss of major parts such as the shaft.

[0072] The assembly structure of the hinge assembly 3, the cabinet body 1 and the cabinet door 2 is as follows: Figure 6 The first hinge 31 is fixed in the cabinet door 2. The cabinet door 2 includes a main board 21 and a sub-board 22 that are engaged with each other. After the main board 21 and the sub-board 22 are engaged, the first hinge 31 is fixed in the cabinet door 2, and a notch 23 is opened on the cabinet door 2 corresponding to the first hinge end 312 of the first hinge 31. The notch 23 has a certain activity space, which can be used for the second hinge 32 to complete the installation with the first hinge 31, and for the first hinge 31 and the second hinge 32 to rotate.

[0073] like Figure 7 , a snap-fit ​​position is provided on the main board 21, and the fixing end 311 of the first hinge 31 is snap-fitted and fixed on the main board 21 by setting the plug-in 214 to snap-fit ​​with the main board 21, and then the sub-board 22 is snap-fitted. Figure 8 Alternatively, by setting a snap-fit ​​position, the fixed end 311 of the first hinge 31 is snap-fitted and fixed by the snap-fitting of the main board 21 and the sub-board 22 .

[0074] like Figure 9 A socket 14 is provided on a side panel 11 of the cabinet body 1, and the side panel 11 is used for rotationally connecting with the cabinet door 2. An elastic foot 323 is provided at the insertion end 321 of the second hinge 32. Figure 3 The elastic foot 323 includes a first foot and a second foot, and a clamping block 324 is arranged at the tail end of the foot. An active space is arranged between the first foot and the second foot, allowing the first foot and the second foot to be squeezed inward.

[0075] The insertion end of the card block 324 has a guiding surface. When the insertion end 321 of the second hinge 32 is inserted into the socket 14, under the extrusion of the guiding surfaces of the respective card blocks 324 of the first and second card feet and the socket 14 socket, the first and second card feet are extruded inward to form a clearance. The insertion end 321 of the second hinge 32 is inserted into the socket 14 until the card block 324 extends out from the other end socket of the socket 14. When the card block 324 extends out of the socket 14 and loses the extrusion effect, the first and second card feet open outward under the elastic action. After opening, the card blocks 324 of the first and second card feet are stuck at the other end socket of the socket 14 to form a limit, thereby realizing the insertion and fixation of the second hinge 32 in the socket 14, as Figure 10 When removing the second hinge 32, only need to simultaneously squeeze the card blocks 324 of the first and second card feet, so that the first and second card feet are extruded inward, and the card block 324 is disengaged from the limit of the other end socket of the socket 14. At this time, pressing the elastic card feet 323 in the direction of the socket 14 can realize the removal of the second hinge 32.

[0076] In this embodiment, by fixing the first hinge 31 on the cabinet door 2, the steps of bulk packaging of the hinge assembly 3 can be reduced. Moreover, since the first hinge 31 is fixed to the cabinet door 2, when packaging or assembling the cabinet door 2, it is not necessary to remove and disassemble the main board 21 and the auxiliary board 22. And when assembling the cabinet 4, the steps of removing the auxiliary board 22 for assembling the first hinge 31 and then assembling the auxiliary board 22 can be reduced.

[0077] By forming a detachable connection between the second hinge 32 and the side plate 11 of the cabinet body 1, the second hinge 32 is used as a flexible mounting part. It can be either assembled with the first hinge 31 first and then assembled on the cabinet body 1, or can be first installed on the cabinet body 1 and then the first hinge 31 is assembled, and it can be flexibly adjusted according to the actual installation of the cabinet door 2 to optimize the assembly of the cabinet door 2 and the cabinet body 1.

[0078] The flexible installation of the second hinge 32 provides the flexibility for the cabinet body 1 to replace different cabinet doors 2 for installation. The second hinge 32 can also be hinged on the first hinge 31 and packaged together with the cabinet door 2, reducing the disassembly and transportation costs. The hinge assembly 3 is not bulk packaged as a spare part, reducing the risk of loss of scattered spare parts.

[0079] In this embodiment, the design is also carried out for the diversified application of the cabinet door 2, such as Figure 11 , a breakable opening 222 is provided on the auxiliary board 22 of the cabinet door 2. The main board 21 of the cabinet door 2 serves as the outer door panel, and the auxiliary board 22 of the cabinet door 2 serves as the inner decorative panel. When the cabinet 4 needs to set the intelligent switch lock function, the circuit is distributed between the main board 21 and the auxiliary board 22, and a battery box 5 or an induction component such as a card swiping recognition type is installed at the breakable opening 222.

[0080] Such as Figure 12, the breakable opening 222 on the secondary board 22, as a part that is easy to break or open, can be conveniently removed when needed for installing the required components. To provide an installation space for the components at the breakable opening 222, an installation cavity 27 is formed between the main board 21 and the secondary board 22 when they are engaged, and the installation cavity 27 is correspondingly arranged with the breakable opening 222.

[0081] In this embodiment, a latch assembly for assembling and positioning in cooperation with the hinge assembly 3 when the cabinet body 1 and the cabinet door 2 are installed is also provided.

[0082] The latch assembly includes a first latch 24 and a second latch 25 vertically arranged on one side edge of the cabinet door 2. The articulated ends of the first latch 24 and the second latch 25 and the first hinge member 31 are on the same axis. At the positions on the cabinet body 1 that cooperate with the first latch 24 and the second latch 25, first pin holes 15 and second pin holes 16 are provided; the first latch 24 protrudes from the cabinet door 2 and is fixedly arranged, and the second latch 25 is telescopic relative to the cabinet door 2 in the vertical direction.

[0083] As Figure 17 , the cabinet body 1 includes an opening formed by an upper cover plate 12, a lower cover plate 13 and two side plates 11, and the cabinet door 2 is used to open and close the opening. The upper cover plate 12 and the lower cover plate 13 protrude from the two side plates 11 and are provided with an upper step edge 17 and a lower step edge 18. Second pin holes 16 and first pin holes 15 are respectively arranged on the upper step edge 17 and the lower step edge 18, and the second pin holes 16 and the first pin holes 15 are arranged on the same side as the side plate 11 where the socket 14 is provided.

[0084] As Figure 15 , the telescopic structure of the second latch 25 is that a chamber 211 is provided at the upper end of the main board 21 near the side where the first hinge member 31 is arranged. The chamber 211 has an activity space. The second latch 25 is movably installed in the chamber 211, and a return spring 26 is fixedly connected between the bottom of the second latch 25 and the bottom of the chamber 211.

[0085] As Figures 13 - 14 , the secondary board 22 is engaged on the main board 21, and an L-shaped groove 221 is provided at the position of the secondary board 22 corresponding to the chamber 211. A slider 251 is provided on the second latch 25. After being engaged, the slider 251 slides into the L-shaped groove 221. By sliding the slider 251 up and down in the vertical groove of the L-shaped groove 221, the second latch 25 can be driven to compress the return spring 26 for up and down telescopic movement.

[0086] Utilizing the bottom horizontal slot of the L-shaped slot 221, when the second bolt 25 retracts, the slider 251 can be slid into the horizontal slot to be stuck, so that the second bolt 25 is maintained in the retracted state. With the arrangement of the L-shaped slot 221 and the slider 251, it is convenient for the installation of the cabinet door 2 and the cabinet body 1. When the cabinet door 2 installs the first bolt 24 and the first pin hole 15 and engages the first hinge member 31 and the second hinge member 32, the retraction of the second bolt 25 can form a clearance, facilitating the side of the cabinet door 2 to be stuck between the upper edge 17 and the lower edge 18 of the cabinet body 1. By the limitation of the horizontal slot of the L-shaped slot 221 and the slider 251, the retracted state of the second bolt 25 can be maintained, and there is no need for manual maintenance of the retraction of the second bolt 25. The installation steps are more simple and fast. After the installation of the cabinet door 2 and the cabinet body 1, the last step only needs to align the second bolt 25 with the second pin hole 16, and the slider 251 is pushed out of the horizontal slot and can be directly snapped into the second pin hole 16 under the action of the return spring 26, and the locking structure is simple.

[0087] In this embodiment, a reserved opening 212 is also provided for the diversified application of the cabinet door 2. The reserved opening 212 is used to place classification cards or number plates. The reserved opening 212 is arranged on the front surface of the main board 21, located on the front surface of the cabinet door 2, which is convenient for identification. The reserved opening 212 is internally provided with a card slot 213. The card slots 213 are arranged on both sides of the reserved opening 212 and are hidden in the reserved opening 212, making it more tidy and beautiful when placing number plates.

[0088] In this embodiment, in order to improve the overall aesthetics of the cabinet 4, the upper cover plate 12 and the lower cover plate 13 protrude from the two side plates 11 and are provided with an upper edge 17 and a lower edge 18. The protruding widths of the upper edge 17 and the lower edge 18 are adapted to the thickness of the cabinet door 2. When the cabinet door 2 is completely closed, the cabinet door 2 is clamped between the upper edge 17 and the lower edge 18, and the front view of the cabinet 4 is overall flat and beautiful.

[0089] In this embodiment, the cooperation between the cabinet door 2 and the upper cover plate 12 when the cabinet door 2 is closed is optimized. For example Figures 18 - 19 , an L-shaped step 171 is arranged below the upper edge 17 of the upper cover plate 12. The cabinet door 2 protrudes from the side plate 11 in the vertical direction. When the cabinet door 2 is closed, the protruding part of the cabinet door 2 is clamped on the L-shaped step 171. When the cabinet door 2 is repeatedly opened and closed, the collision and jamming phenomena between the cabinet door 2 and the upper cover plate 12 can be reduced.

[0090] The second embodiment, refer to Figures 21 - 22 .

[0091] This embodiment provides a door splicing structure for a splicing cabinet. The door splicing structure includes a hinge assembly 3 and a bolt assembly. This embodiment provides a hinge assembly 3 different from the first embodiment. Specifically, the hinge assembly 3 includes a first hinge member 31 and a second hinge member 32, and the first hinge member 31 and the second hinge member 32 are detachably and rotatably connected.

[0092] The first hinge member 31 is installed on the door 2, and the second hinge member 32 is installed on the cabinet body 1. The opening or closing of the door 2 relative to the cabinet body 1 is realized through the rotational connection between the first hinge member 31 and the second hinge member 32.

[0093] As Figure 21 , a limiting block 325 is provided on the second hinge member 32, and the limiting block 325 is arranged on one side of the second hinge member 32 for rotatably connecting with the first hinge member 31. The limiting block 325 is arranged on the outer side of the second hinge member 32. When the second hinge member 32 is installed on the cabinet body 1, the limiting block 325 protrudes towards the outer side of the cabinet body 1, as Figure 22 .

[0094] The function of the limiting block 325 is to limit the maximum opening degree of the door 2. When the door 2 is opened outwards, the first hinge member 31 rotates outwards and will abut against the limiting block 325 provided on the second hinge member 32. The limiting block 325 restricts the continuous rotation of the first hinge member 31. The protruding arrangement of the limiting block 325 can limit the excessive rotation of the door 2 and prevent it from colliding with the cabinet body 1 and being damaged, and can also avoid the situation where the first hinge member 31 rotates excessively and jams with the second hinge member 32, resulting in the jamming of the hinge assembly 3 and the inability to close the door 2.

[0095] The third embodiment, refer to Figure 23 .

[0096] This embodiment provides a door splicing structure for a splicing cabinet. The door splicing structure includes a hinge assembly 3 and a bolt assembly. The hinge assembly 3 is the hinge assembly described in the first embodiment or the second embodiment.

[0097] On the basis of the first embodiment, this embodiment provides another structure of the bolt assembly. Specifically, the bolt assembly includes two groups of second bolts 25 vertically arranged on one side edge of the door 2, and the two groups of second bolts 25 are arranged on the same side as the first hinge member 31. The two groups of second bolts 25 are respectively arranged at the upper end and the lower end of the side edge of the door 2.

[0098] At the positions on the cabinet body 1 that cooperate with two groups of second bolts 25, a first pin hole 15 and a second pin hole 16 are provided, and the two groups of second bolts 25 are respectively inserted into the corresponding first pin hole 15 and second pin hole 16. The second bolt 25 is vertically telescopic relative to the cabinet door 2, and a locking member is provided between the second bolt 25 and the cabinet door 2 for locking or releasing the telescopic movement of the second bolt 25. In this embodiment, the telescopic structure of the second bolt 25 and the locking member are the same as the structure of the second bolt 25 in the first embodiment.

[0099] Retractable second bolts 25 are provided at both the upper and lower parts of the cabinet body 1 for assembly positioning during the installation of the cabinet body 1 and the cabinet door 2. For example Figure 23 , when both groups of second bolts 25 are retracted, the side of the cabinet door 2 can be more conveniently stuck on the side of the cabinet body 1, and the assembly of the first hinge member 31 and the second hinge member 32 can be better carried out.

[0100] As mentioned above, only the preferred specific embodiments of the present utility model are described, but the design concept of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model who makes non-substantial modifications to the present utility model using this concept shall fall within the scope of infringement of the protection of the present utility model.
