Description

Technical Field

[0001] The utility model relates to the field of socket boards, and particularly to a telescopic and expandable socket board. Background Art

[0002] The existing telescopic and expandable socket boards are divided into mobile type or fixed type; the mobile type generally includes a socket board body, a cable and a plug, so the socket board body can be arranged movably as needed; the fixed type is provided with pins on the socket board body and directly inserts the pins into the socket on the wall surface; therefore, the fixed socket board depends entirely on the connection between the pins and the socket to achieve fixation. Since the panel of the general socket protrudes out of the wall surface, after the pins on the back of the socket board are fixed to the socket, only a small area of the back of the socket board is in contact and supported with the panel of the socket, and there are often gaps between most of the area of the back of the socket board and the wall surface. During plugging and unplugging, the socket board is likely to tilt and fall off due to uneven force. In addition, the socket board and the socket are only connected by pins, and its instability increases the possibility of pin damage. Content of the Utility Model

[0003] Based on the above problems, the purpose of the utility model is to provide a telescopic and expandable socket board that can improve the fixation and support effect between the socket board and the wall surface.

[0004] In view of the above problems, the following technical solution is provided: A telescopic and expandable socket board, including a socket board body and an expansion plug. The socket board body is provided with a plurality of expansion sockets, and the expansion plug is provided with pins, and the pins are located at the rear side wall position of the expansion plug; the expansion plug is provided with a telescopic member connected to the socket board body and telescopically arranged relative to the expansion plug. The telescopic direction of the telescopic member is the same as the horizontal direction of the rear side wall of the expansion plug and perpendicular to the plugging and unplugging direction of the pins. The rear side wall of the expansion plug and the rear side wall of the socket board body are parallel to each other and arranged at intervals in a staggered manner, and when the rear side wall of the expansion plug abuts against the socket, the rear side wall of the socket board body abuts against the wall surface.

[0005] In the above structure, when the pins are inserted into the socket, the rear side wall of the expansion plug fits with the panel of the socket. At this time, the rear side wall of the staggered socket board body fits and supports with the wall surface, so that the socket board body is closer to the wall surface and supported or fixed with the wall surface relative to the expansion plug, thereby avoiding the possibility of the socket board body tilting and falling off during the plugging and unplugging state.

[0006] The utility model is further arranged such that a peripheral wall is provided between the front and rear side walls of the socket board body, and the end of the telescopic member is connected to the peripheral wall.

Therefore, setting the rotary disk can enable the pins to rotate and adjust following the rotary disk to ensure that the plug board body can face the correct direction; the adjustment direction is within the range of 0 - 180 degrees.

[0022] The present utility model is further configured such that a plurality of connection holes are provided on the peripheral wall, and the connection holes are provided with easily detachable covers. The outer edge of the easily detachable cover is connected to the connection hole through connection points; the easily detachable cover of the connection hole adapted to the extension plug is removed by disconnecting the connection points to provide space for the installation of the extension plug.
