The electrical cabinet 100 according to the present utility model may include a cabinet body 10 having an opened installation side, a fitting mechanism 30, and a mounting panel 21 connected to the installation side of the cabinet body 10 via the fitting mechanism 30, the mounting panel 21 being closed at the installation side of the cabinet body 10 during use to make the appearance of the electrical cabinet 100 attractive, while the mounting panel 21 may be easily removed from the cabinet body 10 when maintenance of internal electrical components is required to simplify the operation and improve the working efficiency.

In particular, the mounting panel 21 may be shaped to fit the mounting side of the cabinet 10 to allow it to close when approaching the mounting side of the cabinet 10 in the mounting direction. The peripheral side of the mounting panel 21 may be provided with first and second mounting plates 23 extending toward the cabinet 10 to cover opposite peripheral side sections of the cabinet 10, the first and second mounting plates 23 extending transversely relative to each other in a mounting plane perpendicular to the mounting direction such that sections of the first and cabinet 10 relative to the first mounting plates are connected in a releasable connection of the limit slots 31 and limit tabs 32, and sections of the second mounting plates 23 and cabinet 10 relative to the second mounting plates 23 are connected in a fixed connection of the fasteners 33.

In the embodiment shown in fig. 1 to 6, the cabinet 10 may be a hexahedral structure having a cavity formed therein and an open front side, which may be formed by connecting the left side plate 11, the cover plate 12, the right side plate 13, the bottom plate 14, and the back plate together, for example, by welding or by means of screws or the like in a known manner. It should be noted that the directions "front", "rear", "left", "right", "up" and "down" described in the present utility model can be understood by the orientations of the back plate, the left side plate 11, the right side plate 13, the cover plate 12 and the bottom plate 14. Further, the mounting panel 21 may be coupled to the front side of the cabinet 10 to close the internal cavity of the cabinet 10 to form an internal mounting space, and thus, the directions "inside" and "outside" as referred to in the present utility model may be understood as being relative to the side of the cabinet 10 and the mounting panel 21 coupled together where the internal mounting space is located and the side where the external environment is located.

As shown, the mounting panel 21 may be shaped and sized to substantially fit the open front side of the cabinet 10 to just close the cabinet 10, the first mounting plate may extend rearwardly from opposite left and right sides of the mounting panel 21 to the left and right surfaces of the cabinet, i.e., left and right first mounting plates 22 and 24, respectively, and the second mounting plate 23 may extend rearwardly from the upper side of the mounting panel 21 to the upper surface of the cabinet 10 to cover a portion of the left and right side plates 11, 13 and cover 12 of the cabinet 10, i.e., left, right and upper sections of the cabinet 10, respectively. Similar to the cabinet 10, the mounting panel 21 and its peripheral first and second mounting plates 23 may be welded together or connected by means of screws or the like. In an embodiment not shown, the underside of the mounting panel 21 may also extend rearwardly against the lower surface of the cabinet 10 to form a third mounting plate to further close the cabinet 10.

In an embodiment not shown, the first mounting plate may extend rearwardly from the upper side of the mounting panel 21 against the upper surface of the cabinet 10, and the second mounting plate may extend rearwardly from opposite left and right sides of the mounting panel 21 against the left and right surfaces of the cabinet 10, respectively. Compared to the case shown in fig. 1 to 6, which is applicable to the upper side of the electric cabinet 100 with the operation space left and right sides without the operation space, this embodiment, which is not shown, can be applied to the case of the upper side of the electric cabinet 100 with the operation space left and right sides without the operation space left.

As shown in fig. 2-4, the mating mechanism 30 may include at least two limit slots 31, at least two limit tabs 32, and at least one fastener 33.

The at least two limit slots 31 may be distributed, preferably uniformly, in the left and right side sections of the cabinet 10. As shown, the number of limit slots 31 may be 4 and distributed in left and right sections of the cabinet 10 at intervals. The limit slot 31 may extend rearward from the front edge of the section where it is located, thereby facilitating the mounting of the corresponding limit tab 32 thereto from the front side thereof.

The at least two limit protrusions 32 may be disposed on the left and right first mounting plates 22 and 24 of the mounting panel 21 in one-to-one correspondence with the at least two limit slots 31, and extend from the located first mounting plate toward the other first mounting plate through the corresponding limit slot 31 to the inside of the cabinet 10. That is, the limit projection 32 of the left first mounting plate 22 extends rightward into the inside of the cabinet 10 through the corresponding limit slot 31 on the left section, and the limit projection 32 of the right first mounting plate 24 extends rightward into the inside of the cabinet 10 through the corresponding limit slot 31 on the right section. In this way, each of the limit protrusions 32 may overlap to the corresponding limit slot 31, and since the left and right first mounting plates 22 and 24 are located outside the left and right sections, respectively, the limit slot 31 and the limit protrusion 32, which are engaged with each other, may facilitate mounting the mounting panel 21 to the cabinet 10 and prevent the mounting panel 21 from moving in the left and right directions with respect to the cabinet 10. Alternatively, the travel limit of the limit slot 31 may facilitate alignment of the mounting panel 21 and the cabinet 10 when the corresponding limit tab 32 is moved into abutment to the end of travel, thereby facilitating attachment of the fastener 33.

For example, the fasteners 33 may be screws and the number may be selected to be two as shown, and the fasteners 33 may be threaded through corresponding through holes in the second mounting plate 23 to the upper section of the cabinet 10 to secure the mounting panel 21 and the cabinet 10 together. The fastener 33 may be a self-tapping screw or a general screw. When the fastener 33 is a conventional screw, the upper section is provided with a threaded hole aligned with the through hole in the plate of the second mounting plate 23 and adapted to the external thread of the conventional screw.

Thus, when the electrical cabinet 100 of the present utility model is assembled, the mounting panel 21 is brought close to the cabinet 10 from the front side of the cabinet 10, and the stopper protrusions 32 on the left and right first mounting plates 22 and 24 are respectively seated in the corresponding stopper grooves 31 on the left and right sections of the cabinet 10, and then the second mounting plates 23 and the cabinet 10 are fastened together from the upper side by the fasteners 33. When the electrical cabinet 100 is viewed from the front side, the front surface of the electrical cabinet 100 is smooth and flat and various mounting parts are not present. The upper side fastener 33 can be removed directly when it is necessary to disassemble the electrical cabinet 100, i.e., the mounting panel 21 can be moved forward relative to the cabinet body 10 to detach the limit projection 32 from the limit slot 31, which is particularly advantageous when the electrical cabinet 100 is arranged adjacent to a wall or a plurality of electrical cabinets 100 are arranged in a group of electrical cabinets in the left-right direction.

As shown in fig. 4 to 6, the limit protrusion 32 may include a connection rod 321 and a limit ring 322. Considering that each of the limit protrusions 32 and each of the limit grooves 31 are configured in the same manner, for convenience of explanation, one limit protrusion 32 on the left side first mounting plate 22 and its corresponding limit groove 31 will be described as an example.

The connecting rod 321 may be fixed to the left first mounting plate 22, for example, by a threaded connection. Illustratively, the connecting rod 321 may be configured, for example, as a clinch screw that may be pressed through the left first mounting plate 22 from outside the left first mounting plate 22 such that the trailing end may press against the material on the left first mounting plate 22 to deform into a shape-fit with the trailing end, whereby the connecting rod 321 is connected to the left first mounting plate 22 and from the left first mounting plate 22 enters the inside of the cabinet 10 through the corresponding limit slot 31 on the left section. In other embodiments not shown, the connecting rod 321 may also be provided with external threads on the outer periphery of its section adjacent to the trailing end, and the left first mounting plate 22 may be correspondingly provided with threaded holes, so that the connecting rod 321 may be screwed into the threaded holes on the left first mounting plate 22 to connect the two.

As shown, the limiting rings 322 may be sleeved to the outer circumference of the section of the connecting rod 321 extending beyond the left first mounting plate 22, and the limiting rings 322 may extend in a direction transverse to the extending direction of the connecting rod 321, i.e., up-down direction, with respect to the connecting rod 321 and be spaced apart in the left-right direction with respect to the left first mounting plate 22, so as to cooperate with the left first mounting plate 22 to clamp the edges of the corresponding limiting slots 31, thereby further limiting the movement of the mounting panel 21 with respect to the cabinet 10.

The stopper ring 322 may include a first stopper portion 322a and a second stopper portion 322b, the first stopper portion 322a and the second stopper portion 322b may preferably be integrally formed, and the second stopper portion 322b may have a radial dimension greater than that of the first stopper portion 322a. The second limiting portion 322b may have an inner thread at an inner circumference thereof, which may be screwed with the connecting rod 321 with respect to the section outer circumference of the corresponding limiting groove 31. As shown in fig. 6, the axial dimension of the first limiting portion 322a may be substantially equal to or slightly greater than the thickness of the left section, and the radial dimension may be substantially equal to the width of the corresponding limiting groove 31, so that the first limiting portion 322a may just fall into the corresponding limiting groove 31 when screwed to the connecting rod 321.

The second limiting portion 322b is located at a side, far from the left side, of the first mounting plate 22, inside the first limiting portion 322a, and the radial dimension of the second limiting portion 322b is greater than the width of the corresponding limiting slot 31, so that the second limiting portion and the left side first mounting plate 22 are disposed at two sides of the first limiting portion 322a to clamp the edge of the corresponding limiting slot 31, and further limit the movement of the mounting panel 21 relative to the cabinet 10 in the left-right direction. In an embodiment not shown, the first and second limiting portions 322a and 322b may take other shapes, such as quadrangular or irregular shapes, etc., which are only required to achieve the above-described functions.

As shown in connection with fig. 2, the limit slot 31 may include a first slot portion 311 and a second slot portion 312 in communication with the first slot portion 311. The first groove portion 311 of the limit groove 31 on the left side section may extend rearward from the front side edge of the left side section, i.e., the side adjacent to the mounting panel 21, and the width of the first groove portion 311 may be designed approximately to just allow the corresponding limit projection 32, i.e., the corresponding first limit portion 322a, to be placed. The second groove portion 312 may have a width equal to that of the first groove portion 311 and extend downward from the rear end of the first groove portion 311, and the corresponding stopper protrusion 32 put in from the first groove portion 311 falls downward to the lower end side of the second groove portion 312, respectively. Each of the stopper protrusions 32 is overlapped to the corresponding second groove portion 312 by gravity, and the L-shaped designs of the first groove portion 311 and the second groove portion 312 prevent the mounting panel 21 located in the second groove portion 312 from moving in the front-rear direction with respect to the cabinet 10. Preferably, the transition of the first and second groove portions 311, 312 may be designed as a smooth transition to reduce possible damage to the stop collar 322 moving therebetween.

When assembling the electrical cabinet 100 in the present utility model, the connecting rod 321 may be first pressed to each of the first mounting plates 22 from the outside of the left and right first mounting plates 24, and then the corresponding stopper ring 322 is screwed from the inside of the first mounting plate to the section where the connecting rod 321 extends through the first mounting plate such that the first stopper portion 322a thereof abuts against the inside of the first mounting plate and the second stopper portion 322b cooperates with the first mounting plate to form the accommodation space. Subsequently, the first limiting portion 322a enters the first groove portion 311 from the front side of the cabinet 10, while the corresponding receiving space engages the edge of the first groove portion 311, and the mounting panel 21 is continued to move backward until the first limiting portion 322a can drop down into the second groove portion 312. Finally, the second mounting plate 23 and the cabinet 10 are fixed by the fasteners 33. When it is desired to remove the electrical cabinet 100, the fasteners 33 may first be removed, then the mounting panel 21 lifted up along the second slot portion 312 until no further movement is possible, and then the mounting panel 21 moved forward along the first slot portion 311 until the cabinet 10 is removed, contrary to the sequence of assembly processes described above.

As shown in connection with fig. 1 and 2, the left outer end surface of the connecting rod 321 on the left first mounting plate 22 is flush with the left outer surface of the left first mounting plate 22, for example, the connecting rod 321 using a clinch screw may be pressed until its tail end is aligned with the mounting plate. Thus, the outer surface of the connecting rod 321 and the mounting plate on which it is mounted may be coated with a coating to further improve the appearance of the electrical cabinet 100 in the present utility model.

It should be understood that although the present disclosure has been described in terms of various embodiments, not every embodiment is provided with a separate technical solution, and this description is for clarity only, and those skilled in the art should consider the disclosure as a whole, and the technical solutions in the various embodiments may be combined appropriately to form other embodiments that will be understood by those skilled in the art.

The foregoing is illustrative of the present utility model and is not to be construed as limiting the scope of the utility model. Any equivalent alterations, modifications and combinations thereof will be effected by those skilled in the art without departing from the spirit and principles of this utility model, and it is intended to be within the scope of the utility model.
