[0033] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0034] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0035] Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0036] First embodiment: Please refer to Figure 1 , Figure 2 As shown, the first embodiment of this utility model provides an electrical cabinet 10, which is mainly used for installing electrical equipment. It can be applied to a head rack or head cabinet. Of course, the electrical cabinet can also be applied to other occasions such as distribution boxes, terminal cabinets, etc., and is not limited to head racks.

[0037] First, the directional terms mentioned in this embodiment, such as "up" and "down", are only relative directions, that is, the directions when the electrical cabinet 10 is placed on the ground. If the electrical cabinet 10 is placed in a different way, the directional terms can be changed according to the situation.

[0038] The electrical cabinet 10 provided in this embodiment has an adjustable door opening direction, meaning it can be installed as a left-opening structure or assembled as a right-opening structure, thus enabling the electrical cabinet 10 to be used in relatively narrow spaces. For example, assuming the left side of the electrical cabinet 10 is against a wall, the electrical cabinet 10 can be installed as a left-opening door; assuming the right side of the electrical cabinet 10 is against a wall, the electrical cabinet 10 can be installed as a right-opening door.

[0039] For specific details, please refer to... Figures 3-9 As shown, the electrical cabinet 10 mainly consists of a cabinet body 11, a cabinet door 15, and several door stops 16. The cabinet door 15 and the door stops 16 are both installed on the cabinet body 11.

[0040] The shape and structure of the cabinet 11 are not limited and can refer to existing technologies. For example, the cabinet 11 is roughly square prism with a rectangular cross-section, or the cabinet 11 is hexagonal prism, etc. The cabinet 11 has a receiving cavity, the size of which can be set as needed.

[0041] In this embodiment, the structure of the cabinet 11 can adopt, but is not limited to, the following scheme: the cabinet 11 includes a frame 120 and a skin 130. The skin 130 covers the frame 120. The frame 120 serves as the skeleton of the cabinet 11 and mainly plays a supporting role. The skin 130 encloses the four sides of the cabinet 11 (except for the cabinet opening 110).

[0042] The frame 120 includes two side frames 121 and two connecting frames 122. The two side frames 121 are arranged opposite to each other, and the two connecting frames 122 are located between the two side frames 121. The top and bottom ends of the two connecting frames 122 are connected by the connecting frames 122 respectively, and they are roughly in the shape of quadrangular prisms.

[0043] Each side frame 121 can be assembled from several four-fold plates 123, and the connecting frame 122 includes several six-fold plates 124.

[0044] Please combine Figure 10 , Figure 11 As shown, the structure of the four-fold plate 123 is as follows: The four-fold plate 123 is made from a flat plate through a bending process. The cross-section of the four-fold plate 123 is rectangular, with a strip gap on one side of the rectangle. Specifically, the four-fold plate 123 includes a first plate, a second plate, a third plate, a fourth plate, and a fifth plate bent sequentially. The angles between the first and second plates, between the second and third plates, between the third and fourth plates, and between the fourth and fifth plates are preferably 90°. The first, second, third, fourth, and fifth plates form a rectangular structure. The first and fifth plates are flush and have a strip gap between them. The first and fifth plates are each provided with a first self-tapping screw hole. The number of first self-tapping screw holes is not limited and can be set as needed, such as fifteen or fifty. Of course, in other embodiments, the second, third, and fourth plates may also be provided with first self-tapping screw holes or other through holes.

[0045] Please combine Figure 12 As shown, the structure of the six-fold plate 124 is as follows: the four-fold plate 123 is made from a flat plate through a bending process. The six-fold plate 124 includes a sixth, seventh, eighth, ninth, and tenth plate that are bent sequentially. The sixth and tenth plates are parallel and staggered, and the sixth, seventh, eighth, ninth, and tenth plates are roughly distributed in a G-shape. The two ends of the ninth plate are bent to form the eleventh and twelfth plates, which close the two ends of the six-fold plate 124. The width of the seventh plate is smaller than the width of the ninth plate. The tenth, eleventh, and twelfth plates are provided with second self-tapping screw holes. The number of second self-tapping screw holes is unlimited and can be set as needed, such as five, ten, fifteen, etc. The seventh plate is provided with mounting holes 111 for installing the door stop 16. The mounting holes 111 can be blind holes, through holes, self-tapping screw holes, etc.

[0046] In addition, the ninth plate of some or all of the six-fold plate 124 may also be provided with a strip-shaped grounding hole or a self-tapping screw hole.

[0047] As an optional solution, the side frame 121 also includes several corner brackets 125, which are connected to the two adjacent four-fold plates 123 by threaded fasteners, and the six-fold plate 124 is connected to the four-fold plate 123 by threaded fasteners.

[0048] The structure of cabinet 11 can be disassembled and assembled at any time as needed, and the four-fold panels 123 and six-fold panels 124 can be reused. The height, width, and depth of cabinet 11 can be adjusted arbitrarily. The structure is lightweight, flexible and versatile, and can be used in various occasions and needs. It has strong versatility, low maintenance costs, and can be customized to meet more equipment needs.

[0049] In other embodiments, the cabinet 11 may be made of only a number of panels spliced ​​together, or injection molded from rigid plastic, or the four-fold panel 123, six-fold panel 124, etc. may be replaced with angle steel, etc.

[0050] Cabinet 11 is provided with cabinet opening 110, through which staff can enter cabinet 11 or inspect the equipment inside cabinet 11. If the side frame 121 of cabinet 11 is made of four-fold plates 123 spliced ​​together, then both the left and right sides of cabinet opening 110 are composed of four-fold plates 123.

[0051] The location and number of cabinet openings 110 are not limited. For example, cabinet openings 110 may be provided only on one side of the cabinet body 11, or on the adjacent two sides of the cabinet body 11, or on the opposite sides of the cabinet body 11. In this embodiment, it is preferable to provide cabinet openings 110 on the opposite sides of the cabinet body 11.

[0052] The shape and size of the cabinet opening 110 are not limited. For example, the cabinet opening 110 can be rectangular, trapezoidal, etc. Generally speaking, the shape of the cabinet opening 110 is preferably rectangular, which is convenient for production and operation.

[0053] The cabinet door 15 is rotatably mounted on the cabinet opening 110. When the cabinet door 15 rotates, it can open or close the cabinet opening 110.

[0054] The left and right sides of the cabinet door 15 are selectively pivoted to the cabinet opening 110, that is, the left side of the cabinet door 15 is pivoted to the cabinet opening 110 or the right side of the cabinet door 15 is pivoted to the cabinet opening 110. Furthermore, the connection between the cabinet door 15 and the cabinet opening 110 can be changed between the left and right pivot connections.

[0055] Please combine Figure 9 As shown, the pivot connection refers to the presence of a pivot shaft 150 between the cabinet door 15 and the cabinet opening 110. The pivot shaft 150 can be located on the cabinet door 15 or on the cabinet opening 110. The cabinet door 15 can rotate relative to the cabinet opening 110 around the pivot shaft 150, thereby allowing the cabinet door 15 to open or close. When the left side of the cabinet door 15 is pivotally connected to the cabinet opening 110, the cabinet door 15 can open to the left; when the right side of the cabinet door 15 is pivotally connected to the cabinet opening 110, the cabinet door 15 can open to the right.

[0056] The cabinet door 15 has a pivot end and a movable end. The pivot shaft 150 is located at the pivot end, and the cabinet door 15 can rotate around the pivot end. The movable end refers to the end of the cabinet door 15 that is away from the pivot shaft 150.

[0057] Specifically, the connection between cabinet door 15 and cabinet opening 110 can adopt, but is not limited to, the following schemes: Cabinet door 15 and cabinet opening 110 are respectively provided with pivot assemblies, which include pivot shaft 150 and pivot hole 151. Pivot shaft 150 and pivot hole 151 are inserted into each other, that is, a portion of pivot shaft 150 can be inserted into pivot hole 151, and pivot shaft 150 can rotate around its own center line. If pivot shaft 150 is provided on cabinet door 15, then pivot hole 151 is provided on cabinet opening 110; if pivot shaft 150 is provided on cabinet opening 110, then pivot shaft 150 is provided on cabinet door 15. In other embodiments, pivot hole 151 can also be replaced with a bearing, that is, one of the inner ring or outer ring of the bearing is connected to pivot shaft 150 and the other is connected to cabinet door 15 or cabinet opening 110, etc.

[0058] The number of pivot groups is unlimited, but generally there are two. One pivot group is set between the top side of the cabinet door 15 and the cabinet opening 110, and another pivot group is set between the bottom side of the cabinet door 15 and the cabinet opening 110. The pivot shafts 150 of the two pivot groups need to be set coaxially.

[0059] If the pivot 150 is located on the cabinet body 11, the pivot 150 is detachably connected to the cabinet body 11; if the pivot 150 is located at the cabinet opening 110, the pivot 150 is detachably connected to the cabinet door 15.

[0060] For example, the pivot shaft 150 includes a first pivot shaft 150 and a second pivot shaft 150. The first pivot shaft 150 is detachably disposed at the bottom end of the cabinet opening 110 and is inserted into the pivot hole 151 of the cabinet door 15. The second pivot shaft 150 is detachably disposed at the top end of the cabinet door 15 and is inserted into the pivot hole 151 of the cabinet opening 110.

[0061] The detachable connection method between the pivot shaft 150 and the cabinet door 15, or between the pivot shaft 150 and the cabinet body 11, is not limited. For example, it can be a snap-fit ​​connection or a connection via threaded fasteners. Preferably, it is a connection via threaded fasteners. The pivot shaft 150 can be installed or removed simply by disassembling and assembling the threaded fasteners, making the operation simple and convenient. For example, the pivot assembly also includes a fixing block, which can be plate-shaped or block-shaped. The fixing block is provided with a through hole, and the pivot shaft 150 is fixed to the fixing block. The fixing block is connected to the cabinet door 15 or the cabinet opening 110 via threaded fasteners.

[0062] Generally speaking, at the same time, only one of the two pivot assemblies can be installed on the left or right side of the cabinet door 15 and the cabinet opening 110. Of course, in special cases, pivot assemblies can be installed on both the left and right sides of the cabinet door 15 and the cabinet opening 110, but it is necessary to ensure that only one side of the pivot assembly can function at the same time.

[0063] Furthermore, to facilitate the disassembly and assembly of the cabinet door 15, in some embodiments, the pivot shaft 150 may also include a pivot spring. The second pivot shaft 150 is telescopic, and the pivot spring gives the second pivot shaft 150 a tendency to insert into the corresponding pivot hole 151. The type of pivot spring is not limited; it can be a compression spring or a tension spring, etc. Preferably, the pivot spring is a compression spring, which is sleeved on the second pivot shaft 150 and its two ends abut against the second pivot shaft 150 and the cabinet door 15, respectively. Under no external force, the pivot spring can push the second pivot shaft 150 outward, thereby enabling it to be inserted into the pivot hole 151. When the second pivot shaft 150 is compressed, the pivot spring can be compressed or stretched, thereby enabling the second pivot shaft 150 to disengage from the pivot hole 151, thus allowing the cabinet door 15 to be removed from the cabinet body 11 for easy replacement of the cabinet door 15 or relocation of its installation position. Of course, in some embodiments, the pivot shaft 150 may not include a pivot spring. If this is the case, when installing the pivot shaft 150, the later-installed pivot shaft 150 must be inserted into the pivot hole 151 before the pivot shaft 150 can be fixed to the cabinet door 15 or the cabinet body 11.

[0064] A number of mounting holes 111 are provided around the cabinet opening 110. The number of mounting holes 111 is not limited and can vary. Generally, there are more mounting holes 111 on the sides of the cabinet opening 110 and fewer at the top and bottom. The style of the mounting holes 111 is not limited and can be round, square, etc. In this embodiment, the mounting holes 111 are self-tapping screw holes. Furthermore, some or all of the first self-tapping screw holes on the four-fold plate 123 or some or all of the second self-tapping screw holes on the six-fold plate 124 can be used as mounting holes 111.

[0065] Please combine Figure 7 As shown, the door stop 16 is installed at the cabinet opening 110. The position of the door stop 16 is not limited and can be set as needed. Generally speaking, the door stop 16 is usually installed on the side of the cabinet opening 110 away from the pivot end of the cabinet door 15. That is, when the cabinet door 15 closes the cabinet opening 110, the door stop 16 is adjacent to the movable end of the cabinet door 15.

[0066] The number of door stops 16 is unlimited, such as one, two, three, eight, etc. The door stops 16 are connected to the cabinet body 11 by threaded fasteners, that is, the threaded fasteners pass through the door stops 16 and mate with the corresponding mounting holes 111. The threaded fasteners can be self-tapping screws or bolts, and the mounting holes 111 can be self-tapping screw holes or non-self-tapping screw holes.

[0067] It should be noted here that the phrase "the door stop 16 is selectively installed in the mounting holes 111" in this embodiment means that: generally, there are many mounting holes 111, and the door stop 16 only corresponds to some of them. The mounting holes 111 corresponding to the door stop 16 are different at different locations. The door stop 16 can match the mounting holes 111 at various locations, thereby allowing the position of the door stop 16 to be changed, and providing a variety of selectable installation positions for the door stop 16. The meaning of "selective" in other parts of this embodiment refers to this definition.

[0068] The structure of the door stop 16 is not limited and can be plate-shaped, block-shaped, etc. In this embodiment, the door stop 16 is made of angle steel or angle iron, etc. The cross section of the door stop 16 is L-shaped. The L-shaped door stop 16 includes a first side and a second side. The included angle between the first side and the second side can be 90° or about 90°. Preferably, the first side and the second side are perpendicular.

[0069] At least one side of the door stop 16 is provided with a fixing hole 160, that is, the first side of the door stop 16 is provided with a fixing hole 160, or both the first and second sides of the door stop 16 are provided with fixing holes 160. The fixing hole 160 matches the mounting hole 111, that is, a bolt can pass through the fixing hole 160 and the mounting hole 111 and be threaded with a nut, or a self-tapping screw can pass through the fixing hole 160 and be threaded with the mounting hole 111, thereby fixing the door stop 16 and the cabinet 11.

[0070] The door stop 16 prevents the cabinet door 15 from encroaching into the cabinet body 11. That is, when the cabinet door 15 is closed, it abuts against the door stop 16, preventing it from rotating further into the cabinet body 11. In existing technology, the door stop 16 is typically constructed using a folded and welded design. However, this structure cannot be repositioned and consumes a significant amount of sheet metal. Using the door stop 16 structure in this embodiment, only two to three door stops 16 are needed to achieve the same function, significantly reducing sheet metal consumption. Of course, a single door stop 16 can also achieve the same function, but the cabinet door 15 may deform under excessive pressure.

[0071] Correspondingly, the movable end of the cabinet door 15 is provided with several latches 153. The latches 153 are retractable and can be inserted into or disengaged from the corresponding door stop 16 to lock or unlock the cabinet door 15. That is, when the latches 153 are extended, they can be inserted into the second side of the door stop 16, and the operator cannot pull the cabinet door 15 outward; when the latches 153 are retracted, they are no longer blocked by the second side of the door stop 16, and the operator can pull the cabinet door 15 open.

[0072] Of course, in other embodiments, there is no mating relationship between the latch 153 and the door stop 16. Instead, the latch 153 forms a locking relationship with other structures of the cabinet opening 110. For example, the cabinet opening 110 is provided with a lock hole and the latch 153 can be inserted into the lock hole when it is extended, or the latch 153 can be inserted into the strip gap of the four-fold plate 123 when it is extended.

[0073] The number and position of the latches 153 are not limited. For example, in this embodiment, latches 153 are respectively provided at the middle, top, and bottom of one side of the cabinet door 15. Correspondingly, the door stop 16 includes a first door stop 16 and two second door stops 16. The first door stop 16 is installed at the middle of one side of the cabinet opening 110, and the two second door stops 16 are respectively installed at the upper and lower ends of the cabinet opening 110. It is also possible for the latches 153 and the door stops 16 to correspond one-to-one, or for some latches 153 to correspond to some door stops 16.

[0074] Furthermore, in some embodiments, please refer to Figure 8 , Figure 14 As shown, the maximum opening angle of the cabinet door 15 can also be limited by the limiting member 17. The limiting member 17 is detachably and selectively installed in the mounting hole 111 by a threaded fastener. The limiting member 17 is adjacent to the hinge end of the cabinet door 15. The limiting member 17 is configured to limit the maximum opening angle of the cabinet door 15. The maximum opening angle is not limited in degree, such as 90°-180°.

[0075] The limiting component 17 does not prevent the cabinet door 15 from opening and closing normally. However, once the cabinet door 15 has rotated to its maximum opening angle, it cannot continue to rotate. This structure limits the range of the opening angle of the cabinet door 15, preventing the cabinet door 15 from opening too wide and affecting the normal use of other structures.

[0076] The structure of the limiting member 17 that limits the maximum opening angle of the cabinet door 15 is not limited. In this embodiment, the following schemes can be adopted, but are not limited to: the limiting member 17 is provided with a limiting groove 170, the pivot end of the cabinet door 15 is provided with a limiting part 171, and the limiting part 171 extends into the limiting groove 170.

[0077] The limiting member 17 is installed at the cabinet opening 110. Generally, the limiting member 17 is adjacent to the pivot end of the cabinet door 15. The limiting member 17 and the cabinet body 11 are detachably connected by threaded fasteners, that is, the threaded fasteners pass through the limiting member 17 and are connected to the mounting hole 111. The width of the limiting groove 170 is not limited and can be set as needed.

[0078] The style of the limiting part 171 is not limited; it can be rod-shaped, plate-shaped, block-shaped, etc. The limiting part 171 can be part of the cabinet door 15 or can be set independently of the cabinet door 15.

[0079] When the cabinet door 15 rotates around the pivot shaft 150, the limiting part 171 can move within the limiting groove 170. The limiting groove 170 has a preset angle stop point. That is, when the limiting part 171 reaches the preset angle stop point, the limiting part 171 abuts against the side wall of the limiting groove 170, preventing the cabinet door 15 from continuing to rotate.

[0080] The width of the limiting groove 170 and the position or size of the limiting part 171 may affect the maximum opening angle of the cabinet door 15, and can be designed according to actual needs.

[0081] Of course, the structure of the limiting member 17 and the limiting part 171 can also be omitted. That is, in other embodiments, the cabinet 11 can be without the limiting member 17 and the cabinet door 15 can be without the limiting part 171.

[0082] As an optional solution, the top and bottom of the cabinet 11 are provided with wiring holes and sealing plates 112. The sealing plates 112 slide with the cabinet 11 to change the open area of ​​the wiring holes.

[0083] As an optional solution, the cabinet 11 is equipped with a height-adjustable side beam 140. The two ends of the side beam 140 are detachably connected to the four-fold plates 123 on both sides of the side frame 121 by threaded fasteners. The vertical position of the side beam 140 can be changed, which facilitates the installation of other structures or other electrical equipment of the column head frame.

[0084] The side crossbeam 140 is provided with a number of alternating square holes 141 and round holes 142. The number of square holes 141 and round holes 142 can be set as needed, and can be more or less. Generally speaking, the more square holes and round holes 142 there are, the greater the positional accuracy of other structures of the column head frame. Of course, the "alternating distribution" mentioned here does not simply mean that there is one round hole 142 between two square holes 141 and one square hole 141 between two round holes 142. It can also mean that there are several round holes 142 between two square holes 141 and several square holes 141 between two round holes 142, or that a hole row composed of multiple square holes 141 and a hole row composed of multiple round holes 142 are arranged in parallel with each other at intervals.

[0085] The assembly square hole 141 is configured for installing a retaining nut. A retaining nut refers to a nut with a retaining connector mounted on its outer side. The retaining connector has opposing retaining lugs. By pinching the retaining lugs, the distance between the two lugs can be changed, allowing the retaining connector to engage with the assembly square hole 141. Using a retaining nut facilitates the installation and fixation of other structures on the column head frame. The assembly round hole 142 is configured for installing a self-tapping screw. The structure of the self-tapping screw can refer to existing technology and will not be described further here.

[0086] In addition, the top of the cabinet 11 is provided with several lifting rings 113. The connection between the lifting rings 113 and the cabinet 11 is not limited. It can be fixed, integrally formed, or detachable. The lifting rings 113 can be lifted by a crane to adjust the position of the electrical cabinet 10.

[0087] Second embodiment: Please refer to Figure 15 As shown, the first embodiment of this utility model provides a column head rack 100, which is mainly used in data centers and integrated cabling systems. It is a dedicated cabinet located at the end of each column of cabinets in a cabinet array, just like a main switch or distribution center, responsible for providing centralized power or network connection to the entire column of business cabinets.

[0088] The column head frame 100 includes a frame body 20 and the aforementioned electrical cabinet 10, with the frame body 20 housed within the electrical cabinet 10.

[0089] Please combine Figure 16 As shown, the style of frame 20 is not limited and can refer to existing technology, which will not be elaborated here.

[0090] The connection method between the frame 20 and the electrical cabinet 10 is not limited, such as snap-fit, welding, or connection by threaded fasteners. In this embodiment, the frame 20 is provided with several uprights, and the uprights are provided with bearing holes. The bearing holes correspond to the assembly square holes 141 and assembly round holes 142 on the side crossbeam 140. The threaded fasteners can pass through the bearing holes and connect with the assembly round holes 142, or the threaded fasteners can pass through the bearing holes and engage with the clip nuts in the assembly square holes 141, etc.

[0091] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
