[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention.

[0021] Please refer to Figure 1 , a door stopper structure for a power distribution cabinet, comprising a cabinet body, the cabinet body is rotatably connected with a cabinet door through a hinge mechanism, and a door stopper is arranged between the cabinet body and the cabinet door.

[0022] Please refer to Figure 2 , the door stopper includes a connecting rod 1 and a connecting rod 2 which are rotatably connected. The connecting rod 1 is rotatably connected below the cabinet body, and the connecting rod 2 is rotatably connected with the cabinet door, restricting the maximum opening angle of the cabinet door.

[0023] A convex plate 3 is fixedly connected to the inner side of the cabinet door, which is convenient for rotatably connecting with the end of the connecting rod 2.

[0024] Please refer to Figure 2 and Figure 3 , an annular zigzag chute 31 is concavely formed at the upper end of the convex plate 3. A row of teeth 311 is vertically arranged on the inner wall of the chute 31. The row of teeth 311 meshes with a gear 4, and the gear 4 is rotatably connected with the end of the connecting rod 2. When the gear 4 moves in the chute 31, it drives the movement of the connecting rod 2 and the connecting rod 1.

[0025] A telescopic member 5 is rotatably connected to the upper end of the gear 4 in the horizontal direction. In the natural state, the end of the telescopic member 5 can abut against the cabinet door. When the gear 4 rotates, it drives the telescopic member 5 to rotate. Without being restricted, the telescopic member 5 abuts against the cabinet door once every time the gear 4 rotates one week.

[0026] The telescopic member 5 abuts against a U-shaped limiting member 7 in the vertical direction. The U-shaped limiting member 7 causes the inner side of the U-shaped limiting member 7 to abut against the outer circumference of the telescopic member 5, and the end of the U-shaped limiting member is rotatably connected with the convex plate 3. Such a structural design restricts the circumferential rotation of the telescopic member 5, and the telescopic member 5 is always perpendicular to the movement track of the gear 4, that is, the telescopic member 5 is always perpendicular to the zigzag chute 31.

[0027] The way that the end of the U-shaped limiting member is rotatably connected with the convex plate 3 is: a ball is provided at the end of the U-shaped limiting member 7, and a ring of raceway 32 matched with the ball is provided on the convex plate 3. The raceway 32 has the same shape as the zigzag chute 31, so that the movement of the U-shaped limiting member 7 is synchronized with the telescopic member 5.

[0028] Please refer to Figure 3 and Figure 4 , a convex strip 6 protrudes horizontally from the inner side of the cabinet door. A slideway 61 is concavely formed in the convex strip 6 in the horizontal direction. The height of the slideway 61 is the same as the height where the telescopic member 5 is located. A plurality of positioning pits 611 are concavely formed on the slideway 61. In this embodiment, there are three positioning pits 611, and the end of the telescopic member 5 is adapted to the inner wall of the positioning pit 611.

[0029] In this embodiment, the specific structure of the telescopic member 5 is that a spring is built into the telescopic member 5, and a first metal sleeve is sleeved outside the spring. One end of the first metal sleeve is closed and arc-shaped, and is adapted to the inner wall of the positioning pit 611. The spring leaks out from one end of the first metal sleeve and is fixedly connected above the gear 4 in the horizontal direction. The leaked part is sleeved with a second metal sleeve, and the second metal sleeve is fixedly connected above the gear 4. The first metal sleeve and the second metal sleeve are partially sleeved to complete the telescopic movement of the telescopic member 5. The structural design of the telescopic member 5 is not the protected content of this application.

[0030] When the telescopic member 5 slides into the positioning pit 611, the telescopic member 5 is fixed, the gear 4 stops moving and rotating, and then the movement of the first telescopic connecting rod 1 and the second connecting rod 2 is restricted, and the cabinet door is positioned.

[0031] When the end of the telescopic member 5 slides into the leftmost positioning pit 611, the cabinet door is positioned in a state of opening at a smaller angle, which is sufficient to allow one person to wire or repair the cabinet body; when the end of the telescopic member 5 slides into the rightmost positioning pit 611, the cabinet door is positioned in a state of opening at a larger angle, which is sufficient to allow two to three people to wire or repair the cabinet body. The staff can rotate the cabinet door to multiple different angular positions and stop the door according to the work requirements.

[0032] The depths of the multiple positioning pits 611 increase from left to right, and the depths of the slideways 61 between two adjacent positioning pits 611 also increase from left to right in sequence. With such a structural design, the integrated slideway 61 is in a stepped shape, and the left side of the inner wall of the positioning pit 611 is higher than the right side, as Figure 5 shown. While ensuring that the telescopic member 5 can be stuck in the positioning pit 611, it is convenient for the staff to slide the telescopic member 5 into the next positioning pit 611.

[0033] The left end of the slideway 61 is set to be arc-shaped, and the left end of the slideway 61 is connected to the inner side of the cabinet door. When the cabinet door is in the closed state, the gear 4 and the telescopic member 5 are located at the leftmost end of the square-shaped chute 31. When opening the door, the telescopic member 5 begins to abut against the inner wall of the cabinet door and gradually abuts against the left end of the slideway 61. Through the arc-shaped design of the left end of the slideway 61, the telescopic member 5 can smoothly slide into the slideway 61.

[0034] When continuing to open the cabinet door, the gear 4 moves towards the inner end of the square-shaped chute 31. At this time, the telescopic member 5 abuts against the positioning pits 611 one by one. The left and right ends of the square-shaped chute 31 are set to be semi-circular structures. When preparing to close the cabinet door, open the cabinet door to the maximum extent, the gear 4 moves to the rightmost end of the square-shaped chute 31, and the telescopic member 5 leaves the slideway 61; when closing the cabinet door, the gear 4 moves along the right semi-circular structure of the square-shaped chute 31 to the outer end, and at this time the telescopic member 5 points to the cabinet body until the gear 4 moves to the leftmost end of the square-shaped chute 31.

[0035] The cabinet body is provided with a notch 8 for accommodating the door stopper, and one end of the connecting rod 1 connected to the cabinet body is placed outside the notch 8, so that when the cabinet door is closed, the door stopper is placed in the cabinet body without being blocked.

[0036] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
