The end part of the fixing piece leaves the limiting opening, and the push rod is not limited by the fixing piece. The elasticity will push the catch bar, thereby making the catch bar push away the cabinet door. That is, when the locking relationship of the cabinet door and the cabinet body is released, the cabinet door can be automatically opened. Mechanical kayser mode between cabinet door and the box is ingenious in this switch board, has promoted the convenience of the operation of opening and shutting the cabinet door.

The cabinet door is used for covering and establishing the box to play the isolation effect, promote the security of switch board. The cabinet wall of one side of cabinet door has been seted up and has been rotated the groove, rotates the groove and runs through the two sides of cabinet door, and the offering in rotation groove provides the installation place for the connecting piece to realize mechanical kayser between cabinet door and box in the connecting piece.

Each electrical component is loaded in the box body, and the box body is used as a main body framework of the power distribution cabinet. The accommodating cavity, the insertion groove and the pushing groove are arranged to provide mounting places for the connecting assembly. The fastening portion is locked by clamping between the cabinet door and the box body through the fan-shaped fastening groove.

Coupling assembling is used for being connected cabinet door and box to realize the mechanical kayser between cabinet door and the box. The connecting piece includes rotation portion, fastening portion and joint portion. The connecting piece is rotatably connected with the cabinet door through the rotating part, and the rotating part is accommodated in the rotating groove and is rotatably connected with the cabinet door.

In order to improve the stability of the rotational connection between the rotating part and the cabinet door, in one embodiment, the rotating part is provided with a limiting ring, the wall of the cabinet door with the rotating groove is provided with an annular limiting groove, the limiting ring is embedded into the annular limiting groove, and the rotating part is rotationally connected with the cabinet door. The limiting ring is matched with the annular limiting groove, and the annular limiting groove plays a limiting role in rotation of the rotating part, so that the connecting piece is prevented from being separated from the rotating groove. So, promoted the rotation between rotation portion and the cabinet door and connected stability, improved the structural stability of switch board. In order to facilitate the user to rotate the connecting piece, in one embodiment, the rotating part is provided with a knob groove. Furthermore, the knob groove is a straight-line-shaped groove. In this way, the user can adjust the connecting piece in a rotating way through an external tool matched with the knob groove. So, be convenient for the user to rotate this connecting piece, promote the operation convenience.

The fastening portion is abutted against the cabinet door through the fan-shaped fastening groove, so that the cabinet door and the box body are locked in a clamping manner. The clamping portion is used for being clamped with the rotating piece so as to drive the rotating piece to rotate.

In order to facilitate the clamping relation between the connecting piece and the rotating piece, in one embodiment, a clamping groove is formed in the middle area of the rotating piece, and the clamping portion is inserted into the clamping groove and clamped with the rotating piece. Like this, insert in the joint groove through joint portion to realize the joint of connecting piece and rotating member. Further, in this embodiment, the joint groove is square groove to do benefit to joint portion to drive the rotating member and rotate. So, promoted the joint stability of connecting piece with the rotating member, promoted the job stabilization nature of this switch board.

The rotating piece is used for driving the fixing piece to move, so that the fixing piece is controlled to be inserted into the limiting opening, or the fixing piece is controlled to leave the limiting opening. In order to realize the meshing relationship between the rotating element and the fixed element, in one embodiment, the fixed element is in a straight strip structure, and one side of the fixed element is provided with a plurality of first teeth. The rotating member has a plurality of second teeth, each of which is disposed around a center of the rotating member. The fixed member is engaged with the rotating member. Like this, in this embodiment, anticlockwise rotation connecting piece, joint portion will drive the rotating member anticlockwise rotation, and the rotating member will stimulate the mounting and leave spacing mouthful, and the mounting loses the butt relation with the catch bar. So, realized the meshing relation of rotating member and mounting, promoted the transmission validity of this switch board structural relation.

The catch bar is used for promoting the cabinet door, and when the mechanical locking relation of cabinet door and box was relieved, the catch bar had played the effect that promotes the cabinet door for cabinet door auto-eject, thereby the user of being convenient for opened the cabinet door. In this embodiment, the catch bar is the cylinder structure to the catch bar promotes the cabinet door. The end part of the push rod, far away from the elastic piece, is directly abutted against the cabinet door, and in order to improve the protection effect on the cabinet door, in one embodiment, a buffer layer is arranged at one end, far away from the elastic piece, of the push rod. The setting of buffer layer has played and has traded the effect of following the protection, avoids the cabinet door impaired at the in-process that is promoted by the catch bar. In this embodiment, the buffer layer is an elastic rubber layer. In another implementation, the buffer layer is a silicone gel layer. Thus, the protection effect on the cabinet door is improved. So, reduced the damage to the cabinet door, promoted the promotion stability to the cabinet door, promoted the durability of this switch board.

The elastic piece is used for pushing the push rod to move. When the drawing piece is inserted into the limiting opening, the push rod is completely accommodated in the push groove, and the elastic piece is in a compression deformation state at the moment. When the drawing piece leaves the limiting opening, the push rod is not limited by the fixing piece any more, the elastic piece recovers elastic deformation, and the elastic piece generates elastic force to push the push rod to leave the push groove. The catch bar will partly expose the promotion groove to push away the cabinet door through the mode of butt, thereby be convenient for the user to open the cabinet door. In this embodiment, the elastic member is a compression spring, thereby ensuring good elastic force. Further, in order to enhance the connection stability between the elastic member and the push rod and between the elastic member and the box body, in one embodiment, one end of the elastic member is welded to the box body at the bottom of the push groove, and the other end of the elastic member is welded to the end of the push rod. Therefore, the push rod, the elastic piece and the box body are stable in connection, and the push rod and the elastic piece are not easy to separate from the push groove.
