[0028] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0029] See also Figure 1-7 The present invention provides a power strip with replaceable socket units, comprising a mounting base 1 and at least two socket units 2 detachably mounted on the mounting base 1, wherein a socket 21 is sunken in the middle of the socket unit 2, and a mounting platform 22 is provided on the upper end surface of the socket unit 2 around the socket 21, and a downwardly extending protrusion 23 and an outwardly extending card plate 24 for engaging with the protrusion 23 on the adjacent socket module for positioning and connection are provided on the bottom surface of the mounting platform 22, and an alignment hole 25 is provided on the card plate 24, and the alignment hole 25 is adapted in shape to the protrusion 23.

[0030] When the socket units 2 are installed firmly, the protrusions 23 and the alignment holes 25 corresponding to the two adjacent socket units 2 are aligned up and down, so that the protrusions 23 gradually overlap with the alignment holes 25 until the two adjacent socket units 2 are firmly installed. Through the fixed installation between the socket units 2, the assembled at least two socket units 2 are restrained by each other. When the connection between one of the socket units 2 and the mounting base 1 is loose, the other adjacent socket units 2 still maintain a stable connection with the mounting base 1, so that the loose socket unit 2 is restrained and fixed by the adjacent stable socket units 2, avoiding the loose single socket unit 2 from falling off the mounting base 1, effectively improving the overall installation strength, thereby increasing the service life of the product, and the connection structure between the socket units 2 is simple. After the installation is completed, the connection structure is covered and hidden by the mounting plate 22, maintaining the overall aesthetics of the strip usage surface. When the old socket unit 2 needs to be replaced and disassembled, it is only necessary to adjust the angle between the adjacent socket units 2 so that the protrusions 23 and the alignment holes 25 are misaligned to unlock the installation, which is convenient and efficient to operate.

[0031] The present invention has various embodiments with different numbers and positions of the protrusions 23 and the clamping plates 24 , and several embodiments are described in detail below.

[0032] Example 1: Figure 3 As shown, in the embodiment of the utility model, the number of the protrusions 23 provided on one side of the mounting plate 22 of the socket unit 2 is one, and the number of the card plate 24 provided on the other side is also one, that is, a single socket unit 2 is provided with a protrusion 23 without a card plate 24 on one side, and a card plate 24 without a protrusion 23 on the other side. The protrusions 23 and the card plates 24 between two adjacent socket units 2 are arranged corresponding to each other, so that the socket units 2 can be installed in combination with each other, thereby increasing the overall installation stability of the power strip.

[0033] Example 2: Figure 4-6As shown, in the embodiment of the utility model, the mounting plate 22 of the socket unit 2 is staggered along one side edge with two groups of protrusions 231 and card plates 1 241, and the other side of the mounting plate 22 is staggered along the edge with two groups of protrusions 232 and card plates 242. The protrusions 1 231 and card plates 1 241 are centrally symmetrically arranged relative to the protrusions 232 and card plates 242. That is, two protrusions 23 and two card plates 24 are respectively provided on both sides of a single socket unit 2. When two adjacent socket units 2 are assembled, the card plate 1 241 on one side of one socket unit 2 corresponds to the protrusion 2 232 on the opposite side of the other socket unit 2, and the corresponding protrusion 1 231 corresponds to the card plate 2 242 of the other socket unit 2. Due to the staggered arrangement, the two adjacent socket units 2 are first crossed and then connected and fixed by the two groups of protrusions 23 and card plates 24 to realize the combined installation of the socket units 2.

[0034] Compared with the above two embodiments, in the first embodiment, by setting a connection relationship between a group of protrusions 23 and card plates 24, when the adjacent socket units 2 are disassembled and assembled, the mounting platforms 22 of the two adjacent socket units 2 can always maintain a relatively horizontal state. However, its defect is that when a plurality of socket units 2 are assembled in a row, most of the socket units 2 are connected to the two adjacent socket units 2 on both sides, and the socket unit 2 closest to the edge is only connected through the protrusions 23 or card plates 24 on one side, wherein the socket unit 2 connected to the whole body through the protrusions 23 is pressed down by the adjacent card plates 24, and the socket unit 2 connected to the whole body through the card plates 24 is in an upward direction. It is movable upward. If the connection between the socket unit 2 and the mounting base 1 is loose, it is easy to move upward when subjected to vibration, causing the overall combined connection to loosen from this end, affecting the overall installation stability. In embodiment 2, by setting a connection relationship between multiple groups of protrusions 23 and card plates 24, when assembling or disassembling, the mounting platforms 22 of two adjacent socket units 2 must have an angle to allow all the protrusions 23 to be detached from the card plates 24 at the same time. Therefore, after a row of socket units 2 are assembled and installed, the socket units 2 at both ends are restricted from moving in the upward direction, achieving a further limiting effect, so that the implementation method of embodiment 2 has stronger stability than that of embodiment 1.

[0035] like Figure 2 and Figure 7 As shown, in the present invention, a T-shaped long groove 11 for assembling the socket unit 2 is provided on the inner wall of the mounting base 1, and the two ends of the T-shaped long groove 11 are opened at the two ends of the mounting base 1. One end of the mounting base 1 is provided with an end cover 15. The mounting base 22 of the socket unit 2 is provided with vertical plates 221 extending downward on both sides. The vertical plates 221 are provided with T-shaped sliders 222 used in conjunction with the slide groove 12, wherein Figure 7 for Figure 2Schematic diagram of the assembly state of the mounting base 1 and the socket unit 2 with the middle end cover 15 disassembled. When multiple socket units 2 in the utility model are combined with each other and connected in a row, the T-shaped sliders 222 on adjacent socket units 2 are connected in a straight line, so that the socket units 2 assembled in a row are assembled into the mounting base 1 as a whole from one end of the T-shaped long groove 11 through the T-shaped slider 222, and finally the end cover 15 is installed and fixed to one end of the mounting base 1, so that the installed socket unit 2 is limited and fixed along the sliding direction. The arrangement of the above structure facilitates the installation and disassembly of the socket unit 2, improves the assembly efficiency, and can quickly complete the combined installation work of multiple socket units 2; makes the combination of multiple socket units 2 more regular and stable, ensures the firmness of the socket unit 2 as a whole in the mounting base 1, and improves the reliability of use.

[0036] Furthermore, guide edges 223 are provided at both ends of the head of the T-shaped slider 222, which play a good guiding role in the assembly process, so that the socket unit 2 can slide more smoothly into the T-shaped long groove 11 in the mounting base 1, further improving the convenience of installation. The presence of the guide edge 223 helps to ensure that the T-shaped slider 222 accurately enters the T-shaped long groove 11 during the installation process, reduces the instability factors caused by installation deviation, and reduces the difficulty of installation. Even non-professionals can easily install and disassemble the socket unit 2, so that when the user needs to replace the socket unit 2, he can disassemble and replace it by himself, which is simple to operate and has high replacement efficiency.

[0037] like Figure 7 As shown, in the utility model, a slide groove 12 is further provided on the inner surface of the mounting base 1, and the slide groove 12 is located above the T-shaped long groove 11. In this embodiment, two slide grooves 12 are symmetrically provided on the left and right sides of the inner surface of the mounting base 1. The slide groove 12 is slidably equipped with a sliding cover 13 for covering or exposing the socket unit 2 below. The sliding cover 13 can cover or expose the socket unit 2 at any time according to actual needs, meeting the instant adjustment needs of the socket use in different scenarios, such as effectively blocking external dust, debris and possible liquid splashing, reducing the risk of damage caused by external factors.

[0038] like Figure 1 and Figure 2As shown, in the utility model, a detachable cover plate 14 is installed on the mounting base 1, and an opening 141 is provided on the cover plate 14. A push-pull block 131 with an upward protrusion height higher than the opening 141 is fixed on the sliding cover 13. When the user moves the position of the sliding cover 13 by pushing the push-pull block 131, its exposure can be adjusted according to the usage requirements of the corresponding socket module. When the socket units 2 on the mounting base 1 are composed of a variety of sockets of different specifications, their number is also selected by the user. The cover plate 14 is detachable and can be provided with cover plates 14 of different sizes and specifications of openings 141. The cover plate 14 is installed accordingly according to the number of socket units 2 that the user needs to assemble, so that it is more adaptable and practical, which is beneficial for users to adjust and use according to diverse needs without affecting the overall aesthetics.

[0039] The above description is only a preferred embodiment of the present application and does not constitute any form of limitation to the present application. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present application fall within the scope of the technical solution of the present application.
