Description

Technical Field

[0001] The utility model relates to the field of electronic equipment, in particular to a power line extender. Background Art

[0002] Power cord extenders are mainly used to solve the problem of insufficient wire distance. When electronic equipment needs to be placed far away from a power source, a power cord extender can be used to conveniently extend the length of the wire.

[0003] Among them, power cord extenders are particularly popular in home life because they can effectively save space and make it more convenient to connect power sockets to various electronic devices. When the power cord is not long enough, an extension cord should be used to connect one end of the extension cord to the power cord, and the other end is used to connect to the power. Therefore, it is particularly important whether the connection between the power cord and the extender is stable. In some existing families, after connecting the power cord to the extender, they do not care whether the connection is stable and protected. When one end of the extender is pulled and connected to the power interface, the connection is easily disconnected if there is excessive pulling. At the same time, after connecting the power supply, if the connection point is directly exposed to the external environment or rubbed after contact, it is also easy to loosen the plug, which poses a greater safety hazard.

[0037] Example:

[0038] See also Figure 1 - Fig. 9 A power cord extender includes an extender body 1 and a power cord body 101. One end of the extender body 1 is connected to the extender body 1. A stabilizing bottom plate 2, a positioning plate 201 and a pressing plate 202 are provided at the connection between the extender body 1 and the power cord body 101. No less than two groups of positioning plates 201 are provided. The stabilizing bottom plate 2 is used to prevent friction, and the positioning plate 201 and the pressing plate 202 are used to stabilize the connection.

[0039] Some implementation methods of the present application are described in detail below with reference to the accompanying drawings:

[0040] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7The power cord extender of the present application is mainly composed of an extender body 1 connected to a power cord body 101, so that when the power cord body 101 is not long enough, it can be extended after connecting the extender body 1, and the two are connected by inserting one end of the extender body 1 into the interface of the extender body 1. After the connection, the other end can be pulled to connect with an electrical appliance or other equipment. During the pulling process, in order to ensure the stability of the connection between the two, a stable bottom plate 2, a positioning plate 201 and a pressing plate 202 are set at the connection, wherein the positioning plate 201 is set in no less than two groups, which can be located at the extension. The two sides of the connector of the extender body 1 and the power cord body 101 are tightly clamped to ensure stability during subsequent traction and prevent direct disconnection when the other end of the power cord body 101 is pulled. At the same time, the contact points of the extender body 1 and the power cord body 101 can be protected after being set, and the connection points can be separated and placed on a plane in combination with the stable bottom plate 2 to prevent the connector from rubbing during contact and causing the plug to loosen. It can also effectively separate dust and sewage from directly contacting the connection points, so that the connection points can be effectively protected during use to avoid potential safety hazards.

[0041] In some embodiments, the present application provides anti-slip grooves at both ends of the stabilizing base plate 2 and the contacting surface, thereby increasing the friction of the contact surface and avoiding slipping. By opening preset holes 203 at the four corners of the stabilizing base plate 2, when the stabilizing base plate 2 is placed on a certain plane, it can be further fixed with bolts or the like to ensure the stability of the connection.

[0042] In the present application, an elastic clamp 3 is also provided, which has four groups and is respectively located at the front and rear ends on both sides of the stabilizing base plate 2 for further limiting the outside of the connector of the extender body 1 and the power cord body 101. The elastic clamp 3 is an elastic clamp 3 made of plastic. After the stabilizing base plate 2, the positioning plate 201 and the positioning plate 201 are combined and sleeved on the connection between the extender body 1 and the power cord body 101, the elastic clamp 3 can be tightly contacted with the front and rear ends of the tail of the extender body 1 or the power cord body 101 connector to further stabilize the connection end of the extender body 1 and the power cord body 101, and can simultaneously prevent the extender body 1 and the power cord body 101 connector from deviating left and right, thereby improving the use effect.

[0043] See also Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 8In the present application, a positioning structure is also provided, which mainly includes a threaded rotating rod 6, wherein the threaded rotating rod 6 is movably installed in the middle of the elastic clamping plate 3 through a bearing, so that the positioning plate 201 is threadedly connected to the two ends of the threaded rotating rod 6, and the threads set at the two ends of the threaded rotating rod 6 are in opposite directions. By rotating the handle of the threaded rotating rod 6, the positioning plates 201 at both ends are moved away from or close to the end where the extender body 1 and the power cord body 101 are connected under the driving force, so as to adjust the fixed spacing and facilitate the subsequent disassembly of the connection.

[0044] The present application also provides an anti-slip cover 601, which is made of rubber material. When the threaded rotating rod 6 handle is rotated, it can protect the hands and prevent slipping during rotation.

[0045] When applying the repositioning structure, please refer to Fig. 9 The pressing plate 202 is set to be disconnected from the middle, so as to facilitate fastening from both sides where the extender body 1 and the power cord body 101 are connected.

[0046] See also Figure 5 , Figure 6 and Figure 7 , a positioning structure is also provided in the present application. When the positioning structure is applied, the pressure plate 202 can be arranged not to be disconnected from the middle, wherein the positioning structure mainly includes a reset spring 5, one end of the reset spring 5 is installed in the groove of the positioning plate 201, and the other end is installed at the bottom of the pressure plate 202. By pulling up the pressure plate 202, under the action of force, the pressure plate 202 can be driven to move, and the preset hole 203 can be stretched. After the distance between the pressure plate 202 and the stable bottom plate 2 is increased, the extender body 1 and the power cord body 101 plugs are moved to the inside respectively, and then the action of force is stopped to cause them to produce elastic deformation, driving the pressure plate 202 to fix the extender body 1 and the power cord body 101 on the stable bottom plate 2 for longitudinal fixation. The application method can be selected according to the use requirements.

[0047] In the present application, a stabilizing shaft 501 and a movable groove 502 are also provided. The stabilizing shaft 501 is installed at the bottom of the pressure plate 202, and the movable groove 502 is opened inside the positioning plate 201, so that the stabilizing shaft 501 can move inside the movable groove 502. When the pressure plate 202 is driven to move up and down, the stabilizing shaft 501 can move inside the movable groove 502 in the same direction to improve the stability during movement. The protective protrusion 7 is made of rubber material. When the pressure plate 202 is pressed on the positioning plate 201, the protective protrusion 7 is first embedded in the groove at the corner of the positioning plate 201 to protect the collision surface.

[0048] See also Figure 4 , Figure 6 and Figure 7In the present application, an inner concave opening 4 and a convex point 401 are also provided. The inner concave opening 4 is respectively opened at the four corners of the bottom of the stable base plate 2. The inner concave opening 4 surrounds the outside of the preset hole 203. When in use, glue can be dripped into the inner concave opening 4. The convex point 401 provided on the inner wall of the inner concave opening 4 can effectively increase the contact area. When the stable base plate 2 is fixed on a plane by glue, the applicability can be improved to meet more usage needs in the home.
