[0045] Based on the above latch structure, the present application also provides a cabinet door, which includes a cabinet door body 20 and a latch structure. Figure 3 , which is a structural schematic diagram of the cabinet door provided in an embodiment of the present application. In actual use, the latch bracket 10 is set at a corner of the cabinet door body 20 through the limiting shaft 11, specifically, it is set below the side where the cabinet door body 20 is hinged with the cabinet door, so that the offset cabinet door body can be adjusted through the latch structure.

[0046] Specifically, the present application provides a baffle 22 on one side of the cabinet door body 20, and forms a receiving portion 21 for receiving the above-mentioned latch structure between the baffle 22 and the cabinet door body 20, the latch bracket 10 is arranged in the receiving portion 21, and the limiting shaft 11 is arranged to pass through the bottom of the cabinet door body 20.

[0047] As an optional implementation, please refer to Figure 7 , which is a structural schematic diagram of the gasket 32 ​​in the cabinet door provided in the embodiment of the present application, it is also necessary to align the lower edge of the cabinet door body 20 with a shaft sleeve 31 and a gasket 32, and connect the limit shaft 11 to other structures after passing through the cabinet door body 20, the shaft sleeve 31 and the gasket 32 ​​to ensure the smoothness of the cabinet door opening and closing after the cabinet door body 20 is installed with the latch structure.

[0048] As an optional embodiment, a fixing shaft hole 223 and an adjusting shaft hole 224 are provided at positions of the baffle plate 22 corresponding to the fixing hole 123 and the adjusting hole 124. Figure 4 , is a specific embodiment of the cabinet door provided in the embodiment of the present application Figure 1 It can be observed that a plurality of adjusting shaft holes 224 are arranged in an inclined manner and form an inclination angle between the extending directions of the limiting shaft 11 .

[0049] It should be noted that a plurality of adjustment holes 124 may be arranged in an inclined manner in the same direction, corresponding to the attached Figure 4 It is tilted to the right, and can also be tilted to the left as needed. Of course, it can also be tilted alternately, such as the first adjustment shaft hole 224 and the third adjustment shaft hole 224 are tilted to the left, and the second adjustment shaft hole 224 is tilted to the right. The above arrangement settings of the adjustment shaft holes 224 are all feasible, and the present application does not impose further restrictions on this.

[0050] Furthermore, after the positions of the fixed shaft hole 223 and the adjusting shaft hole 224 are set, it is necessary to use the fixing member 15 to sequentially penetrate the fixed shaft hole 223 and the fixing hole 123 to achieve relative fixation between the latch structure and the cabinet door body 20, and use the adjusting member 16 to sequentially penetrate one of the adjusting shaft holes 224 and the adjusting hole 124 at the corresponding position to improve the rising or sinking caused by the axial deviation during the rotation of the cabinet door body 20.

[0051] For details, please continue to refer to Figure 6 , is a specific embodiment of the cabinet door provided in the embodiment of the present application Figure 3 When the cabinet door is in a normal state and no displacement occurs, the latch mechanism can be arranged on the cabinet door body 20 as a rotation axis. At this time, taking the arrangement of three adjustment holes 124 as an example, the fixing member 15 needs to be used to sequentially penetrate the fixed shaft hole 223 and the fixed hole 123, and then the adjusting member 16 needs to be used to sequentially penetrate the second adjustment shaft hole 224 and the corresponding adjustment hole 124.

[0052] Please refer to Figure 4 , is a specific embodiment of the cabinet door provided in the embodiment of the present application Figure 1 When the cabinet door is in a hanging state, that is, it sinks relative to the horizontal plane, the fixing member 15 needs to be used to sequentially penetrate the fixing shaft hole 223 and the fixing hole 123, and then the adjusting member 16 needs to be used to sequentially penetrate the third adjusting shaft hole 224 and the corresponding adjusting hole 124, so as to improve the hanging state of the cabinet door.

[0053] Please refer to Figure 5 , is a specific embodiment of the cabinet door provided in the embodiment of the present application Figure 2When the cabinet door is in an upward state, that is, it is tilted relative to the horizontal plane, it is also necessary to use the fixing member 15 to sequentially penetrate the fixing shaft hole 223 and the fixing hole 123, and then use the adjusting member 16 to sequentially penetrate the first adjusting shaft hole 224 and the corresponding adjusting hole 124, so as to improve the upward state of the cabinet door.

[0054] As an optional embodiment, the direct screw connection through the fixing member 15 and the adjusting member 16 may be more laborious in actual operation. Therefore, the present application provides a first locking hole 221 and a second locking hole 222 at the positions of the baffle 22 corresponding to the first locking point 121 and the second locking point 122. Since the first locking point 121 and the second locking point 122 are protruding from the side wall of the limiting plate 12, the first locking point 121 is set in the first locking hole 221, and the second locking point 122 is set in the second locking hole 222. This can achieve initial position fixation between the latch structure and the cabinet door, avoiding a large displacement of the positions of the two during the screw connection process, which affects the subsequent adjustment work.

[0055] It should be noted that the second positioning hole 222 provided in the present application is in the form of an OB hole, i.e., a long waist hole. In principle, the aperture of the second positioning hole 222 is not less than the projection distance formed by several adjustment holes 124 in the horizontal direction, so as to avoid the aperture of the second positioning hole 222 being too small and unable to cooperate with the above-mentioned inclined several adjustment holes 124.

[0056] Since the latch bracket 10 is provided with a reserved shaft hole 225 between the second positioning hole 222 and the adjacent adjusting shaft hole 224, the present application also provides a reserved hole 125 at the position of the limiting plate 12 corresponding to the reserved shaft hole 225 to avoid damage to the above-mentioned several adjusting holes 124, and also sets the reserved shaft hole 225 in the form of an OB hole, and limits the aperture of the reserved shaft hole 225 to be located between the adjusting hole 124 and the second positioning hole 222, that is, the aperture of the reserved shaft hole 225 should meet the requirement of being larger than the aperture of the adjusting shaft hole 224 and smaller than the aperture of the second positioning hole 222, so as to be used for emergency in the extreme case that the adjusting hole 124 is damaged, and avoid the cabinet door from opening and closing when the axis is offset, causing the protective coating provided on the cabinet door to fall off and rust, thereby shortening the service life of the cabinet door.

[0057] Based on the above-mentioned latch structure and cabinet door, the present application also provides a smart cabinet. For other details about the smart cabinet implementing the above-mentioned technical solution, please refer to the description of the latch structure and cabinet door provided in the above-mentioned application embodiment, which will not be repeated here.

[0058] The latch structure, cabinet door and smart cabinet provided in the embodiments of the present application are provided with a fixing hole and a plurality of adjustment holes on the latch bracket, and a corresponding fixing shaft hole and a plurality of adjustment shaft holes are provided on the cabinet door body. The position fixation between the latch brackets is achieved by a fixing piece, and the adjusting piece is passed through one of the adjustment shaft holes and the adjustment hole at the corresponding position according to actual assembly requirements, so that the rising or sinking caused by the axis deviation during the rotation of the cabinet door body can be improved; the assembly is simple, and the problem of uneven door gaps caused by processing and assembly, installation errors and the dead weight of the door, and the problem of the cabinet door not being able to open and close normally due to rubbing against the edge, is solved; the traditional method of the shaft sleeve cooperating with the end face of the door shaft hole is replaced by the latch bracket, and the galvanized design of the structure avoids the problem of the metal surface protective coating falling off and further rusting due to long-term friction, thereby ensuring the service life of the cabinet door.
