Description

Technical Field

[0001] This utility model relates to the field of socket technology, and more specifically, to a retractable and expandable socket. Background Technology

[0002] Wall sockets are sockets built into the wall, and their specific installation method is fixed during the decoration process; however, in actual use, people often encounter the problem that there are not enough sockets on the sockets; in order to solve this problem, people need to expand the wall sockets.

[0003] Generally, extension cords come in two types: portable and fixed. Portable extension cords have longer power cords, allowing the cord to be moved to the specific location of use. However, due to the long power cord, they take up a lot of space and are not suitable for narrow spaces. Fixed extension cords, on the other hand, have a plug directly installed on the back of the cord, allowing the extension cord to be fixed directly above the wall socket. They are suitable for use in places such as kitchens and bathrooms.

[0004] However, the relative position between the plug and the socket of the existing fixed expansion socket cannot be adjusted, which makes it impossible to fit the expansion socket against the wall and fix it in place; as a result, the expansion socket will wobble relative to the wall, affecting the plugging and unplugging of electrical appliances. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a retractable extension socket.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A retractable extension socket includes a socket body and a plug housing with a plug at one end; a connecting sleeve for plugging into the plug housing is vertically movable on one side of the socket body.

[0008] The connecting part at the other end of the plug housing is slidably disposed inside the connecting sleeve. Limiting hooks are provided on both sides of the connecting part extending inward. Limiting edges that cooperate with the limiting hooks are provided on both sides of the end of the connecting sleeve facing the plug housing.

[0009] Pull the plug housing outwards, and the connecting part slides outwards along the connecting sleeve, and the limiting hook will abut against the corresponding limiting edge.

[0010] The present invention further includes: guide blocks are vertically arranged on both sides of the connecting sleeve, and guide grooves adapted to the guide blocks are provided on the insert plate body.

[0011] The present invention further includes: an abutment plate extending inward from the upper end of the connecting part, the abutment plate abutting against the top wall of the connecting sleeve.

[0012] The present invention further comprises: the plug housing includes a base plate and an upper shell that cooperate with each other; the base plate is provided with a mounting groove for installing the plug; and the base of the plug is rotatably disposed in the mounting groove.

[0013] The present invention further includes: a limiting protrusion is provided in the mounting groove, and an annular limiting groove that cooperates with the limiting protrusion is provided on the lower end surface of the base.

[0014] The present invention further specifies that the arc of the annular limiting groove is 180 degrees.

[0015] The present invention further includes: a plurality of locking hooks spaced apart on the outer edge of the mounting groove, the locking hooks hooking the outer edge of the base and locking the base in the mounting groove.

[0016] The beneficial effects of this utility model are as follows: The plug shell of the extension strip is installed on one side of the strip body via a connecting sleeve. Users can adjust the plug shell according to the thickness and width of the wall socket to be extended. That is, the plug shell with the plug installed can be moved up and down with the connecting sleeve to adjust to a suitable position, and the distance of the plug shell extending outward can be adjusted according to the width from the wall socket hole to the edge of the wall socket to which the plug is to be connected. In other words, by pulling the plug shell outward, the connecting part slides outward along the connecting sleeve to extend the distance between the plug and the strip body. This allows the strip body to fit against the wall and be fixed with adhesives such as glue. This effectively prevents the extension strip from shaking relative to the wall and facilitates the user's plug-in and power-access operations. Attached Figure Description

[0027] See attached document Figures 1 to 9 This utility model provides a more detailed description of a retractable extension socket.

[0028] A retractable extension socket includes a socket body 1 and a plug housing 2 with a plug 21 at one end. The socket body 1 is provided with a plurality of two-hole and three-hole sockets to meet the power needs of more electrical appliances. A connecting sleeve 3 for plugging the plug housing 2 is vertically movable on one side of the socket body 1. The connecting part 22 at the other end of the plug housing 2 is slidably disposed in the connecting sleeve 3. Limiting hooks 221 are provided on both sides of the connecting part 22 extending inward. Limiting edges 31 that cooperate with the limiting hooks 221 are provided on both sides of the connecting sleeve 3 facing the plug housing 2. When the plug housing 2 is pulled outward, the connecting part 22 slides outward along the connecting sleeve 3, and the limiting hooks 221 abut against the corresponding limiting edges 31, which can prevent the plug housing 2 from separating from the socket body 1. That is, the plug housing 2 and the socket body 1 have a better connection structure.

[0029] Because the plug housing 2 of the extension strip is installed on one side of the strip body 1 via the connecting sleeve 3, when installing and using the extension strip, the user can adjust the plug housing 2 according to the thickness and width of the wall socket to be extended; that is, the plug housing 2 with the plug 21 installed can be moved up and down with the connecting sleeve 3 to be adjusted to a suitable position, and the distance of the plug housing 2 extending outward can be adjusted according to the width from the wall socket hole to the edge of the wall socket to which the plug 21 is to be connected. That is, by pulling the plug housing 2 outward, the connecting part 22 slides outward along the connecting sleeve 3 to extend the distance from the plug 21 to the strip body 1; thereby allowing the strip body 1 to fit against the wall and be fixed with adhesives such as glue; effectively preventing the extension strip from shaking relative to the wall, making it convenient for the user to plug in and obtain power.

[0030] The connecting sleeve 3 has guide blocks 32 vertically arranged on both sides of its side walls, and the insert plate body 1 has guide grooves 11 that are adapted to the guide blocks 32; so that the plug shell 2 can move up and down on the insert plate body 1 more smoothly with the connecting sleeve 3.

[0031] The upper end of the connecting part 22 extends inward and is provided with a stop plate 222. After the plug housing 2 is stretched outward, the stop plate 222 abuts against the top wall of the connecting sleeve 3 to prevent the outer end of the plug housing 2 from tilting downward.

[0032] The plug housing 2 includes a base plate 23 and an upper shell that cooperate with each other. The base plate 23 is provided with a mounting groove 231 for mounting the plug 21. The base 211 of the plug 21 is rotatably disposed in the mounting groove 231. A limiting protrusion 2311 is provided in the mounting groove 231. The lower end surface of the base 211 is provided with an annular limiting groove 2111 that cooperates with the limiting protrusion 2311. The arc of the annular limiting groove 2111 is 180 degrees. This allows the plug 21 to be rotated and adjusted according to the direction of the wall socket, thus having better applicability.

[0033] The mounting groove 231 is provided with a plurality of locking hooks 2312 at intervals on its outer edge. The locking hooks 2312 hook the outer edge of the base 211 and lock the base 211 in the mounting groove 231, which facilitates the assembly operation of the plug 21 on the plug housing 2.

[0034] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
