[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] In the description of the present invention, it should be understood that the terms "center", "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0030] The terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Thus, a feature defined as "first", "second", and "third" may explicitly or implicitly include one or more of the features.

[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] like Figures 1 to 6 As shown, in an illustrative embodiment of the limiting support structure of the cabinet door 2 of the utility model, the limiting support structure is installed on a cabinet, the cabinet includes a cabinet body 1 and a cabinet door 2, the cabinet body 1 has a cabinet opening 11 on the front side, the cabinet door 2 is hinged on the cabinet body 1, and an upward flange 12 is provided at the bottom of the cabinet opening 11, and the cabinet door 2 flips and moves between a first position and a second position.

[0033] The limiting support structure comprises a limiting plate 3 , the front end of which is mounted on the back of the cabinet door 2 , and the bottom surface of the rear end is provided with a limiting groove 31 .

[0034] When the cabinet door 2 is in the first position, the cabinet door 2 closes the cabinet opening 11, and the limiting plate 3 extends into the cabinet body 1 through the cabinet opening 11. The cabinet door 2 is opened and moved from the first position to the second position. During the movement of the cabinet door 2, the limiting plate 3 is gradually pulled out of the cabinet body 1 along with the cabinet door 2. When the cabinet door 2 moves to the second position, the limiting groove 31 at the rear end of the limiting plate 3 moves forward to the flange 12, and the flange 12 is inserted into the limiting groove 31 to prevent the limiting plate 3 from moving, thereby limiting and fixing the cabinet door 2 in the state of being opened to the maximum extent.

[0035] In the above-mentioned schematic embodiment, the limiting support structure of the cabinet door is realized by installing a limiting plate 3 on the cabinet door 2, setting a limiting groove 31 at the rear end of the limiting plate 3, utilizing the existing flange 12 on the cabinet opening 11 of the cabinet body 1 and snapping it together, so as to realize the limiting fixation of the cabinet door 2 in the open state. It only has one limiting plate 3, a small number of parts, a simple structure, low production and assembly costs, is not prone to failure, is easy to maintain, is thin and occupies little space, and solves the problems that the current limiting device of the cabinet door 2 has a complex structure, is difficult to install and is prone to failure.

[0036] In some embodiments, when the cabinet door 2 flips and moves between the first position and the second position, the top end of the flange 12 slides on the bottom surface of the limiting plate 3 .

[0037] A transition portion 32 protruding downward is provided on the bottom surface of the limiting plate 3. The transition portion 32 is adjacent to the limiting groove 31, and its bottom surface is an inclined surface. When the flange 12 slides along the bottom surface of the transition portion 32 toward the limiting groove 31, the flange 12 pushes the limiting plate 3 upward to enable it to pass over the transition portion 32 and be inserted into the limiting groove 31.

[0038] More specifically, when the cabinet door 2 moves from the first position to the second position, it first slides on the flat bottom surface of the front part of the limiting plate 3, and then slides along the inclined surface to the transition part 32. When the flange 12 slides on the inclined surface of the transition part 32, the limiting plate 3 is gradually lifted upward. The flange 12 further slides and leaves the transition part 32, and the limiting plate 3 falls, so that the flange 12 is stuck in the limiting groove 31.

[0039] The transition portion 32 that is convex downward and has an inclined surface allows the limit plate 3 to move smoothly as the cabinet door 2 is opened, and guides the limit plate 3 so that the flange 12 passes over the transition portion 32 and is inserted into the limit groove 31, thereby preventing the flange 12 from being stuck on the raised structure on the front side of the limit groove 31 and being unable to move further into the limit groove 31, thereby ensuring that the limiting and fixing effect of the limit plate 3 is stable.

[0040] In some embodiments, a clamping plate 33 extending downward is integrally connected to the rear end of the limiting plate 3 , and the space between the transition portion 32 and the clamping plate 33 constitutes a limiting groove 31 .

[0041] The plate can be directly punched out, and one end of the plate can be bent downward to form the limit plate 3 and the clamping plate 33 at the rear end thereof, which is easy to process. There is no need to machine the limit groove 31 on the surface of the limit plate 3 by turning. By bending one end into the clamping plate 33, the clamping plate 33 and the downward convex transition portion 32 bracket directly form the limit groove 31, making the processing of the limit plate 3 simpler.

[0042] In some embodiments, the transition portion 32 is a transition plate that is integrally connected to an edge of one side of the limiting plate 3 and extends downward.

[0043] A plate is directly punched out, and one side of the plate has a portion with an inclined edge, which is bent downward to form a transition plate. The bottom surface of the transition plate is inclined to form an inclined surface of the transition portion 32, so that the limit plate 3 can be integrally processed by plate stamping and bending, making the processing of the limit plate 3 simpler.

[0044] In some embodiments, the limiting plate 3 is an elastic member. The flange 12 slides along the inclined surface to the transition portion 32, gradually lifting the limiting plate 3 upward, and the elastic force generated by the deformation of the limiting plate 3 acts downward on the flange 12, so that the limiting plate 3 presses down the flange 12, and keeps the bottom surface of the limiting plate 3 in sliding contact with the flange 12, and when the limiting groove 31 is aligned with the flange 12, the elastic force of the limiting plate 3 makes it fall quickly and continuously press down the flange 12, and the flange 12 is quickly and firmly inserted into the limiting groove 31, thereby improving the firmness of the cabinet door 2.

[0045] In some embodiments, the rear end of the transition portion 32 is provided with an arc chamfer 34, which can prevent the rear end of the transition portion 32 from being too sharp and scratching the flange 12. In the process of the flange 12 sliding from the transition portion 32 into the limiting groove 31, it can enter smoothly, and the limiting plate 3 can be prevented from falling quickly and deforming the flange 12. After the limiting plate 3 is manually pushed up to make the flange 12 escape from the limiting groove 31, the arc chamfer 34 can guide the flange 12 to slide onto the transition portion 32, so that the limiting plate 3 can move backward smoothly and close the cabinet door 2 smoothly.

[0046] In some embodiments, the limiting plate 3 is in an arc shape, which is concentric with the hinge point of the cabinet door 2, and the curvature is less than 90 degrees. The arc-shaped limiting plate 3 occupies less space in the front-to-back direction inside the cabinet body 1, ensuring that the cabinet body 1 can accommodate more electrical components. The curvature of the limiting plate 3 is less than 90 degrees, ensuring that when the cabinet door 2 is closed, the rear end of the limiting plate 3 is attached to the inner wall of one side of the cabinet body 1 or is spaced from the inner wall, so as to avoid the limiting plate 3 pressing against the inner wall of the cabinet body 1 and obstructing the cabinet door 2, so that it cannot completely close the cabinet opening 11.

[0047] In some embodiments, the front end of the limiting plate 3 is integrally connected with a connecting plate 35 extending downward, and the connecting plate 35 is attached to the back of the cabinet door 2 and fixedly connected thereto by bolts. The connecting plate 35 is formed by bending a plate, and the processing and manufacturing are simple, and a larger assembly surface is provided for the limiting plate 3 and the cabinet door 2, so that the limiting plate 3 is firmly fixed on the cabinet door 2, stably supporting the limiting plate 3, preventing the limiting plate 3 from tilting, and maintaining the sliding contact between the bottom surface of the limiting plate 3 and the flange 12, so that the flange 12 is stably inserted into the limiting groove 31 for limiting and fixing.

[0048] In some embodiments, the flange 12 further surrounds the cabinet opening 11, and the edge of the back side of the cabinet door 2 is bent to form a surrounding frame 21. When the cabinet door 2 is in the first position, the rear side of the frame 21 is attached to the front side of the flange 12, and the connecting plate 35 is attached to the front side of the frame 21.

[0049] The flange 12 is arranged around the cabinet opening 11, and a frame 21 is arranged around the back of the cabinet door 2. The frame 21 fits with the flange 12, so that when the cabinet door 2 closes the cabinet opening 11, the two are in surface contact, thereby ensuring the sealing of the cabinet. The connecting plate 35 is located in the receiving groove 22 provided in the frame 21, so that the connecting plate 35 is embedded in the frame 21 to avoid it protruding backward relative to the surface of the frame 21, resulting in the frame 21 not being able to completely fit on the flange 12. When the frame 21 is not provided with the receiving groove 22, the connecting plate 35 is attached to the front side of the frame 21, and will not occupy the rear side of the frame 21 in contact with the flange 12, thereby making full use of the space of the cabinet door 2 for installation and fixing, and avoiding obstacles to the surface contact sealing between the cabinet door 2 and the cabinet opening 11.

[0050] In some embodiments, when the cabinet door 2 is in the first position, the rear end of the limiting plate 3 is attached to the inner wall of the cabinet body 1 on the side close to the cabinet door 2. The inner wall limits and supports the cabinet door 2 by supporting the limiting plate 3, so that when the cabinet door 2 quickly flips backward and hits the cabinet opening 11, the inner wall of the cabinet body 1 shares part of the impact force, avoiding the impact force from being concentrated on the cabinet opening 11 and causing the flange 12 to bend backward, which not only prevents the flange 12 from being damaged, but also avoids the flange 12 from being engaged with the limiting groove 31 at a position further back than the second position, thereby reducing the opening of the cabinet door 2.

[0051] Finally, it should be noted that: the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0052] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for which protection is requested in the utility model.
