Description

Technical Field

[0001] The utility model relates to the technical field of sockets, in particular to an anti-dropping plug and socket. Background Art

[0002] Sockets, also known as power sockets and switch sockets. Sockets refer to seats that can be plugged with one or more circuit wiring. Various wiring can be inserted through them, which makes it easy to connect with other circuits. The connection and disconnection between the circuit and the copper parts can ultimately achieve the connection and disconnection of this part of the circuit. As a link between the circuit and the electrical appliance, the socket is an indispensable device.

[0003] The existing socket is prone to causing the plug to fall off during use. When the electrical device moves, the electrical device will drive the plug to move, which may pull the plug off the socket, causing a sudden power outage of the electrical device and damage to the electrical components inside the electrical device, reducing the practicality of the socket.

[0004] The Chinese patent application number 202320596154.6 discloses a socket with anti-dropping plugs, which relates to the technical field of sockets. The socket with anti-dropping plugs comprises a shell, a socket, a plug, and a fixing mechanism. The top surface of the shell is provided with a socket, the top surface of the shell is plugged with a plug, and the inside of the shell is provided with a fixing mechanism. The socket with anti-dropping plugs, by setting a fixing mechanism, sequentially drives the left and right sets of rotating rods to rotate forward, the rotating rod drives the worm to rotate forward, the worm drives the worm gear to reverse, and thus drives the threaded sleeve to reverse. Since the sliding hole limits the moving direction of the fixing plate, thereby limiting the moving direction of the threaded rod, the reversal of the threaded sleeve will drive the threaded rod to move toward the center of the shell, and the threaded rod drives the fixing plate to move toward the plug. The worker controls the horizontal plates at the top of the left and right sets of fixing plates to fit on the card plate on the outer wall of the bottom end of the plug, so that the plug can be fixed to prevent the plug from falling off the socket, which is conducive to improving the practicality of the device. However, there are still some shortcomings in the implementation of this patent. The fixing structure of the plug is relatively complicated, and the staff is required to rotate it during the fixing process. Since the fixing mechanism is small in size, it is difficult to rotate and inconvenient to operate. At the same time, the anti-detachment mechanism of the socket in this patent is an integrated structure with the socket. After the socket is damaged, the anti-detachment mechanism cannot be removed and reused. At the same time, when the plug wire is pulled, the user cannot be reminded of the pulling in time, which causes the plug wire to be easily damaged under the action of a large pulling force or the electrical appliance at the other end of the wire is damaged. Utility Model Content

[0005] The utility model aims to provide an anti-dropping plug and socket to solve the deficiencies in the above-mentioned background technology.

[0011] As a further solution of the utility model: a rotating block is fixedly connected to the outer surface of the installation shaft.

[0012] Beneficial effects of the utility model:

[0013] (1) The plug is inserted into the socket, and then the installation shaft is rotated, which drives the first fixing plate to rotate. Then, the fixing column, the first fixing groove, the first telescopic rod, the first spring and the extrusion block cooperate to prevent the two-pin plug and the three-pin plug on the socket from falling off. The operation is simple and convenient for the user. At the same time, the plug on the five-hole socket can be stably fixed, and the installation of the anti-falling mechanism is convenient. At the same time, when the socket is damaged, the mounting frame can be removed and installed on other sockets to realize the reuse of the anti-falling mechanism.

[0014] (2) After the plug is inserted into the socket, the wire connected to the plug is then fixed to the fixing mechanism on the mounting plate. When the wire connected to the plug is pulled, the wire drives the mounting plate to move. At this time, the second telescopic rod and the second spring contract. At the same time, the mounting plate begins to rest against the trigger switch on the support plate. The trigger switch controls the alarm to start making a harsh sound, which promptly reminds the user, thereby effectively reducing the damage to the wire caused by the pulling force, and also preventing the other end of the plug connection wire from being damaged or falling off from the electrical appliance connection end.
