[0044] Example

[0045] When the door panels of existing low-voltage cabinets used in box-type substations cannot be hinged, they are generally fixed directly with screws, which is inconvenient to open. The screws need to be removed for subsequent door opening. After long-term use, the screws are prone to stripping, increasing the difficulty of maintenance.

[0046] Please refer to Figure 1 , Figure 2 and Figure 3 To solve the above problems, the present embodiment provides a door structure 100 and a low-voltage cabinet 300. The low-voltage cabinet 300 is equipped with the door structure 100, so that the door panel 110 can be detached and conveniently installed in the low-voltage cabinet 300 without using hinges.

[0047] Please refer to Figure 1 , Figure 2 and Figure 3 In this embodiment, the low voltage cabinet 300 includes a cabinet body 310 and a door structure 100 . The door structure 100 is installed in the cabinet body 310 .

[0048] Generally, the cabinet body 310 of the low voltage cabinet 300 has a plurality of partitioned spaces, which are used as different functional areas to install different electronic equipment.

[0049] In this embodiment, the cabinet body 310 is provided with a door opening, and a door frame 170 is installed in the door opening to install the door panel 110 .

[0050] In this embodiment, the door structure 100 includes a door panel 110, a plug-in bracket 130 and a clamping bracket 150. The plug-in bracket 130 is disposed on a first side 111 of the inner side of the door panel 110 and extends outward, and the clamping bracket 150 is rotatably mounted on a second side 113 of the inner side of the door panel 110 and can extend outward after rotation; wherein, the first side 111 and the second side 113 are two opposite sides of the door panel 110, which can be understood as two sides in the width direction or two sides in the length direction of the door panel 110. When the door panel 110 is mounted on the door frame 170, the door panel 110 abuts against the outer side of the door frame 170, and the plug-in bracket 130 and the clamping bracket 150 can be clamped to the inner side of the door frame 170. When the door panel 110 is opened, the clamping bracket 150 is rotated so that the clamping bracket 150 is retracted to the inner side of the door panel 110, and the door panel 110 can be removed from the door frame 170.

[0051] Please refer to Figure 1 , Figure 2 and Figure 3 In this embodiment, a fixed plug-in bracket 130 and a rotatably arranged clamping bracket 150 are arranged on the inner side of the door panel 110. When installing the door panel 110, one side of the plug-in bracket 130 is first inserted, and then the other side is abutted against the outer side of the door frame 170. Then, the clamping bracket 150 is rotated to clamp the clamping bracket 150 on the inner side of the door frame 170. In this way, the door panel 110 abuts against the outer side of the door frame 170, and the plug-in bracket 130 and the clamping bracket 150 are clamped on the inner side. When removing, the clamping bracket 150 is rotated to release the clamping, and then the door panel 110 is moved to remove the door panel 110 from the door frame 170. In the above manner, the door panel 110 can be detachably installed on the door frame 170, so that the door panel 110 can be installed without the need for handover.

[0052] Please refer to Figure 2 , Figure 3 and Figure 4 In this embodiment, the plug-in bracket 130 sequentially connects the first section 131, the second section 133 and the third section 135. A first angle is set between the first section 131 and the second section 133, and a second angle is set between the second section 133 and the third section 135. The first section 131 is fixedly connected to the inner side of the door panel 110, the second section 133 can make the third section 135 spaced from the door panel 110, and the third section 135 can be snapped to the inner side of the door frame 170.

[0053] An interval for avoiding the door frame 170 is formed between the first section 131 and the third section 135 . Such a structure of the plug-in bracket 130 can facilitate the installation of the plug-in bracket 130 and facilitate its clamping on the inner side of the door frame 170 .

[0054] In this embodiment, the first angle and the second angle are both 90 degrees, and the first section 131 and the third section 135 extend in opposite directions, which is convenient for clamping and installation.

[0055] Of course, in some other embodiments of the present application, the angle can also be adjusted, such as 80°, 110°, etc., but it is necessary to ensure that it can be snapped into the door frame 170.

[0056] In this embodiment, the third section 135 at least partially extends out of the first side 111 of the door panel 110, so that the clamping can be more stable.

[0057] Please refer to Figure 2 , Figure 3 and Figure 4 In this embodiment, the door structure 100 further includes a door frame 170, which is disposed on the cabinet body 310. The door frame 170 has a first door beam 171 corresponding to the first side 111 of the door panel 110 and a second door beam 175 corresponding to the second side 113. The first door beam 171 is provided with a slot 173, and the third section 135 is clamped in the slot 173. The first door beam 171 is provided with a slot 173, so that the plug-in bracket 130 is plugged in the slot 173, so that the plug-in bracket 130 can be prevented from moving, thereby achieving better stability. The clamping bracket 150 is clamped on the inner side of the second door beam 175. The door panel 110 abuts against the outer sides of the first door beam 171 and the second door beam 175.

[0058] In this embodiment, there are two plug-in brackets 130, and the two plug-in brackets 130 are arranged at intervals. In some examples, there is one card slot 173, and its width is the same as the width between the two plug-in brackets 130, so that the outer sides of the two plug-in brackets 130 can respectively abut against the two sides of the card slot 173. In other embodiments, one plug-in bracket 130 can also correspond to one card slot 173, so that they are plugged into the slots one by one.

[0059] In this embodiment, the door structure 100 further includes a lock assembly 190 . The lock assembly 190 is installed on the door panel 110 and connected to the clamping bracket 150 . The lock assembly 190 can drive the clamping bracket 150 to rotate.

[0060] By providing the lock assembly 190 and utilizing the lock assembly 190 to drive the clamping bracket 150 to rotate, it will be safer.

[0061] It should be noted that, in the present embodiment, the lock assembly 190 can drive the lock core to rotate when the key is turned, thereby driving the clamping bracket 150 to rotate.

[0062] Of course, in some other embodiments of the present application, for example, when a lock is not required, the connection can be made through other rotatable connecting parts, as long as the outside of the door panel 110 can drive the snap-fit ​​assembly to rotate.

[0063] Figure 2 , Figure 3 , Figure 4 and Figure 5 In this embodiment, the clamping bracket 150 is rotatably connected to the lock core of the lock assembly 190 to form a lock tongue, which makes the installation of the clamping bracket 150 more convenient.

[0064] In this embodiment, the clamping bracket 150 rotatably includes a fourth section 151, a fifth section 153 and a sixth section 155 connected in sequence, a third angle is set between the fourth section 151 and the fifth section 153, and a fourth angle is set between the fifth section 153 and the sixth section 155. The fourth section 151 is connected to the lock core of the lock assembly 190, the fifth section 153 can make the sixth section 155 spaced from the door panel 110, and the sixth section 155 can be clamped to the inner side of the door frame 170.

[0065] This facilitates the installation of the clip bracket 150 and the adaptation to the door frame 170 , so that it can be better clipped to the inner side of the door frame 170 .

[0066] Please refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 Specifically, the fourth section 151 is provided with a connection hole, and a threaded column is generally provided at the end of the lock core, and the connection hole is installed on the threaded column and then fastened by a nut. In order to prevent the clamping bracket 150 from rotating relative to the lock core, a limit surface is generally provided.

[0067] In this embodiment, the third angle and the fourth angle are both 90 degrees, and the extension directions of the fourth section 151 and the sixth section 155 are opposite. When the clamping bracket 150 is rotated to the outside of the door panel 110, the sixth section 155 at least partially extends out of the second side 113 of the door panel 110.

[0068] This makes installation easier and enhances the stability of the snap-in.

[0069] Of course, in some embodiments of the present application, the angle of the included angle can be set according to requirements.

[0070] Please refer to Figure 2 , Figure 3 and Figure 4 In this embodiment, there are two snap-on brackets 150 and two lock assemblies 190. Two openings are provided on the panel at intervals, and then the two lock assemblies 190 are installed on the panel, and the two snap-on brackets 150 are installed on the two lock cores accordingly.

[0071] During the door closing process, the door panel 110 is tilted, and one side of the plug-in bracket 130 is first inserted into the slot. When the plug-in bracket is retracted into the panel, the other side of the door panel 110 is pushed to abut against the outside of the door frame 170. The lock core is turned by the key, so that the plug-in bracket 150 is plugged into the inner side of the door frame 170, thereby completing the door closing.

[0072] During the door opening process, first insert the key into the lock core and rotate the lock core, thereby driving the card bracket 150 to rotate and retract the card bracket 150 into the interior of the door panel 110, then pull the door panel 110 and move the door panel 110 so that the plug-in bracket 130 is removed from the slot, and the door can be opened.

[0073] In summary, in this embodiment, a fixed plug-in bracket 130 and a rotatably arranged clamping bracket 150 are arranged on the inner side of the door panel 110, so that when installing the door panel 110, one side of the plug-in bracket 130 is first inserted, and then the other side is abutted against the outer side of the door frame 170, and then the clamping bracket 150 is rotated to clamp the clamping bracket 150 on the inner side of the door frame 170, so that the door panel 110 abuts against the outer side of the door frame 170, and the inner side is clamped by the plug-in bracket 130 and the clamping bracket 150. When removing, the clamping bracket 150 is rotated to release the clamping, and then the door panel 110 is moved to remove the door panel 110 from the door frame 170. In the above manner, the door panel 110 can be detachably installed on the door frame 170, so that the installation of the door panel 110 can be achieved without the need for handover.

[0074] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
