[0027] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the present invention will be described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure will be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0030] Furthermore, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments. Example 1

[0031] Reference Figure 1 and 2 This embodiment provides a shockproof power distribution cabinet, including: a cabinet body 100, with a side groove 101 on the edge of the cabinet body 100, a partition 102 in the side groove 101, a receiving hole 103 on the partition 102, and a round shaft 104 passing through the receiving hole 103; a cabinet door 200, which is connected to the cabinet body 100 through an adjustment box 300; a central hole 301 passing through the center of the adjustment box 300, the round shaft 104 passing through the central hole 301, and the adjustment box 300 being located in the receiving hole 103.

[0032] The round shaft 104 is embedded in the central hole 301, so that the cabinet door 200 can rotate around the round shaft 104 as an axis, and the adjustment box 300 is restricted in the receiving hole 103 and can only rotate around the round shaft 104; the cabinet door 200 is connected to the adjustment box 300.

[0033] In this embodiment, the side groove 101 is a groove structure set on the side of the side groove 101. Preferably, the side groove 101 is set at the middle of the height direction of the cabinet 100, corresponding to the position of the inlay 201 set in the middle of the cabinet door 200.

[0034] This invention enables the cabinet door 200 to decelerate just before closing during the opening / closing process. Ideally, this deceleration overcomes the resistance that would otherwise prevent the door from being fully closed, allowing it to engage with the latch G. In practical use, the deceleration is often used to prevent the door from being fully open, triggering an alarm to remind the user to close the door properly. Over time, this can overcome the problem of operators slamming the door shut.

[0035] The adjustment box 300 has a first side groove 302 and a second side groove 303 on both sides, and the structure of the first side groove 302 and the second side groove 303 is centrally symmetrical about the middle hole 301. Example 2

[0036] Referring to 1-5, the difference between this embodiment and the previous embodiment is that the first side groove 302 includes a limiting groove 302b placed inside the adjusting box 300 and a connecting groove 302a connecting the limiting groove 302b and the outside; the cabinet door 200 is provided with an insert 201 on its side, the insert 201 includes a connecting rod 201a and a limiting block 201b disposed at the end of the connecting rod 201a; the limiting block 201b is embedded in the limiting groove 302b, and the connecting rod 201a passes through the connecting groove 302a.

[0037] It should be noted that the limiting groove 302b limits the insert 201, so that the insert 201 can only move linearly along the length direction of the limiting groove 302b.

[0038] A pilot block 304 is provided in the second side groove 303. The pilot block 304 includes an embedded part 304a embedded in the second side groove 303 and an actuating rod 304b extending out of the second side groove 303 to the outside. A first circular sawtooth A and a second circular sawtooth B are provided at both ends of the bottom of the first side groove 302 and the second side groove 303. The smooth area C between the first circular sawtooth A and the second circular sawtooth B is smooth.

[0039] The first side groove 302 and the second side groove 303 are disposed on two opposite sides of the adjustment box 300. The insert 201 is T-shaped in general, and the cross-sectional shape and size of the insert 201 are the same as those of the first side groove 302.

[0040] A first spring 302c is provided at one end of the first side groove 302 to connect to one side of the insert 201, and a second spring 302d is provided at the other end of the first side groove 302 to connect to the other side of the insert 201; a third spring 303a is provided at one end of the second side groove 303 to connect to one side of the embedded part 304a, and a fourth spring 303b is provided at the other end of the first side groove 302 to connect to the other side of the embedded part 304a; both the embedded part 304a and the limiting block 201b are provided with a third circular sawtooth D at their ends.

[0041] In this embodiment, the cabinet door 200 is connected to the adjustment box 300 through the connection of the insert 201 and the first side groove 302. Both connections have a T-shaped cross-section. This structure limits the insert 201 to moving only along the length of the first side groove 302. The end of the insert 201 is provided with circular serrations, and the bottom of the first side groove 302 is provided with matching circular serrations. This structure prevents the insert 201 from easily sliding at either end of the first side groove 302, and it only moves when it receives a certain pushing force. This ensures that the cabinet door 200 slows down when it is about to contact the cabinet body 100, avoiding violent collisions; it also ensures that the cabinet door 200 will not shake when fully open, thus preventing swaying and hindering operation.

[0042] Preferably, the first side groove 302 and the insert 201 are also provided with spring connections on both sides to further ensure that the insert 201 will not easily slide when it is in the smooth area C in the first side groove 302, because it will receive the reaction force of the spring when it moves; the connection structure of the pilot block 304 in the second side groove 303 is the same as that of the first side groove 302 and the insert 201.

[0043] Reference Figure 4 During the flipping process of cabinet door 200, the closing action causes cabinet door 200 to drive adjustment box 300 to rotate along circular shaft 104, as shown below. Figure 4 As shown in the diagram, during this process, the cabinet door 200 and the pilot block 304 remain stationary due to the serrated structure at the connection point with the adjustment box 300, and rotate with the adjustment box 300. Alternatively, if a spring is provided and its elasticity is strong, the pilot block 304 will be pushed to the middle position while rotating. During the rotation, the pilot block 304 contacts the partition 102, specifically the edge of the receiving hole 102a. As the rotation continues, the pilot block 304 will continue to receive the reaction force from the edge of the receiving hole 103, thereby causing the pilot block 304 to move relative to the adjustment box 300. That is, the pilot block 304 breaks through the limitation of the serrated structure and slides in the second side groove 303. The cabinet door 200 will experience the same situation as it continues to rotate, eventually reaching the closed state. At this time, the insert 201 reaches the edge of the first side groove 302 and cannot continue to slide, and the pilot block 304 reaches the edge of the second side groove 303 and cannot continue to slide.

[0044] It should be noted that the above situation is an ideal scenario; more often, closing the cabinet door at 200 degrees will only achieve [the desired effect]. Figure 4 The third step in the process.

[0045] More specifically, the pilot block 304 has a first contact F at its end, the receiving hole 103 has a second contact E at its edge, the cabinet door 200 has a third contact H, and the latch G on the cabinet 100 has a fourth contact G. The electrical connection relationship of the four contacts is as follows: Figure 5 As shown, in this circuit, if cabinet door 200 is in the position Figure 4 In the fourth step, when the cabinet is fully closed, the third contact H and the fourth contact G are in contact, the first contact F and the second contact E are in contact, and the buzzer J and the warning light K are not lit; if the cabinet door 200 is in the closed position... Figure 4 In the third step state, the third contact H and the fourth contact G are not in contact, while the first contact F and the second contact E are in contact. The buzzer J sounds and the warning light K lights up to sound an alarm.
