Description

Technical Field

[0001] The utility model relates to a wall-plug type power adapter, belonging to the technical field of power adapters. Background Art

[0002] An adapter is an interface converter. It can be an independent hardware interface device that allows hardware or electronic interfaces to be connected to other hardware or electronic interfaces. It can also be an information interface, such as a power adapter, a tripod base adapter, a USB and serial port adapter, etc. A power adapter is a power supply conversion device for small portable electronic devices and electronic appliances. It is generally composed of a casing, a power transformer and a rectifier circuit. It can be divided into AC output type and DC output type according to its output type, and can be divided into wall-mounted and desktop types according to the connection method.

[0003] There are still some problems in the use of existing wall-plug power adapters. For example, the adapters are placed on the outside of the wall power socket through the plug. Due to the gravity of the adapter itself, the plug will exert a downward force on the power hole inside the power socket. After long-term use, the contact between the plug and the power hole will be poor, thereby affecting the normal use of the adapter. When the adapter needs to be taken down, if the power connection is accidentally touched, leakage may occur, and personal safety cannot be guaranteed. Utility Model Content

[0004] The purpose of the utility model is to provide a wall-plug power adapter. The utility model has a simple structure and is easy to use. It can prevent the adapter's own gravity from causing contact between the plug and the power socket, and at the same time prevent electric shock when taking it, so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A wall-plug power adapter comprises a device body, a plug is fixedly connected to the outside of the device body, a signal line is fixedly connected to the bottom of the device body, an L-shaped plate is fixedly connected to the top of the device body, a slide groove is provided inside the L-shaped plate, a slide rod is slidably engaged inside the slide groove, a slider is fixedly connected to the top of the slide rod, a return spring is fixedly connected to the outside of the slide rod, a connecting rod is fixedly connected to the outside of the slider, a suction cup is fixedly connected to the outside of the connecting rod, a connecting plate is fixedly connected to the top of the L-shaped plate, a threaded tube is fixedly connected to the outside of the connecting plate, a screw is threadedly connected to the inside of the threaded tube, and an extrusion rod is fixedly connected to the outside of the screw.

[0007] Furthermore, a stabilizing plate is fixedly connected to the outer side of the device body, a movable tube is fixedly connected to the outer side of the stabilizing plate, a pushing rod is movably connected inside the movable tube, an extrusion spring is fixedly connected to the outer side of the movable tube, and a force plate is fixedly connected to the outer side of the push rod.

[0008] Furthermore, the sliding block is slidably connected to the top of the L-shaped plate via a sliding rod, and one end of the return spring away from the sliding rod is fixedly connected to the inner wall of the sliding groove.

[0009] Furthermore, the suction cup is fixedly connected to the outer side of the slider via a connecting rod, and the suction cup is located above the device body.

[0010] Furthermore, the extrusion rod is movably connected to the outer side of the connecting plate through a screw rod, and one end of the extrusion rod away from the screw rod is movably connected to the outer side of the sliding block.

[0011] Furthermore, the stabilizing plates are symmetrically distributed on the outside of the device body, and one end of the extrusion spring away from the movable tube is fixedly connected to the outside of the push rod.

[0012] Furthermore, the number of the force plates is the same as the number of the push rods, and the force plates are symmetrically distributed on both sides of the device body.

[0013] The beneficial effects of the utility model are:

[0014] (I) The utility model sets up a device body, and inserts the plug of the device body into the wall power socket, so that the signal line at the bottom of the device body is connected with other devices. After the installation is completed, the screw rod is rotated and moved inside the threaded tube, and the movement of the screw rod drives the extrusion rod to move, thereby squeezing the slider at the top of the L-shaped plate, so that the slider moves under the action of the slide rod and the return spring, and the movement of the slider drives the connecting rod to move, so that the suction cup outside the connecting rod is closely connected with the wall. At this time, the action of the suction cup can reduce the downward gravity of the device body itself, and prevent poor contact between the plug and the power socket after long-term use.

[0015] (ii) The utility model is provided with a device main body, and a stabilizing plate is fixedly connected to the outside of the device main body. When the device main body needs to be taken, the screw is first reversed so that the squeezing rod no longer squeezes the slider. At this time, the slider no longer adsorbs the suction cup to the wall under the action of the return spring on the outside of the slider. Then, the push rod is pressed so that the push rod drives the force plate to squeeze the wall under the action of the squeezing spring. The device main body is moved out from the inside of the wall power socket through the reaction force, and there is no need for direct contact between the hands of personnel and the power socket, thereby preventing electric shock.

[0026] In this embodiment: by setting up a device body 1, by inserting the plug 2 of the device body 1 into the inside of the wall power socket, the signal line 3 at the bottom of the device body 1 is connected to other devices. After the installation is completed, by rotating the screw rod 13, the screw rod 13 is rotated and moved inside the threaded tube 12, and the movement of the screw rod 13 drives the extrusion rod 14 to move, thereby squeezing the slider 7 on the top of the L-shaped plate 4, so that the slider 7 moves under the action of the slide bar 6 and the return spring 8, and the movement of the slider 7 drives the connecting rod 9 to move, so that the suction cup 10 on the outside of the connecting rod 9 is closely connected to the wall. At this time, the action of the suction cup 10 can reduce the downward gravity of the device body 1 itself, and prevent poor contact between the plug 2 and the power socket under long-term use.
