[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figure 1 - Figure 8This invention provides a technical solution: a multifunctional power connection column for furniture, comprising a column assembly 1, with mounting components 2 at both ends of the column assembly 1. The mounting components 2 facilitate the fixed installation of both ends of the column body 11 between the top and bottom of a furniture cabinet or building, serving as an interface for power cord entry and end decoration. The column assembly 1 includes a column body 11, which facilitates bearing the vertical support load of the entire furniture. Inner mounting grooves 14 are formed around the outer perimeter of the column body 11, facilitating the inclusion of nested components. The groove 18, the electrical connector 27, and related conductive components form the assembly reference space for the functional module, and at the same time provide the insertion and installation positioning base for external furniture components such as shelf connectors and clothes rail connectors, realizing the integration of column support function and power supply function. The inner mounting groove 14 has an inner conductive groove 15 on both sides near the middle of the column body 11. The inner conductive groove 15 facilitates the provision of a deep conductive channel for heavy electrical equipment. The heavy electrical equipment is mounted on the inner mounting groove 14 through a sliding base, and the conductive contacts on the sliding base are electrically connected to the inner conductive groove 15. The inner mounting groove 14 has secondary baffles 16 on both sides away from the middle of the column body 11. These secondary baffles 16 facilitate engagement with the fixing blocks 19 of the nested groove strip 18, allowing for detachable engagement and fixation between the nested groove strip 18 and the column body 11. Simultaneously, as part of the sliding guide structure for the power supply terminal, the secondary baffles 16 have fixing protrusions 17 on one side. The inner mounting groove 14 contains the nested groove strip 18, which serves as the mounting carrier for the outer conductive groove 110. The fixing blocks 19, secondary baffles 16, and fixing protrusions 17 detachably engage and fix the strip inside the inner mounting groove 14, providing a shallow power supply channel for lightweight electrical equipment. The lightweight electrical equipment is also mounted in the outer conductive groove 110 via a sliding base, with the conductive contacts of the sliding base electrically connected to the outer conductive strip 114. The sliding base is a commonly used sliding electrical connection base, which will not be described in detail here. The nested groove 18 can be installed or removed according to usage requirements. When installed, it provides an outer conductive groove 110 for light electrical appliances to draw power. When removed, it exposes an inner conductive groove 15 for heavy electrical appliances to draw power, realizing flexible adaptation of the same column to electrical equipment of different power levels. The nested groove 18 has fixing blocks 19 on both sides of its exterior. The fixing blocks 19 are located inside the auxiliary side 16. The fixing blocks 19 facilitate the detachable fixing of the nested groove 18 inside the inner mounting groove 14, making it convenient for the installation and removal of the nested groove 18. The fixing blocks 19 engage with the fixing protrusions 17. The nested groove 18 has an outer conductive groove 110 inside. The outer conductive groove 110 provides a shallow conductive channel for light electrical equipment to draw power, providing a foundation for the installation and use of low-power light electrical appliances.

[0020] As an embodiment of the present invention, an inner mounting strip 111 is fixedly installed inside the inner conductive groove 15, and an inner conductive strip 112 is fixedly installed on one side of the inner mounting strip 111. The inner mounting strip 111 serves as an insulating mounting base for the inner conductive strip 112, which is used to fix the inner conductive strip 112 inside the inner conductive groove 15 and maintain electrical insulation between the inner conductive strip 112 and the column body 11. The inner conductive strip 112 is used to contact the contacts on the connector when the heavy electrical connector is inserted into the inner conductive groove 15, so as to transmit power from the connector 27 to the electrical equipment.

[0021] As an embodiment of the present invention, further, an external mounting strip 113 is fixedly installed inside the external conductive groove 110, and two external conductive strips 114 are fixedly installed on one side of the external mounting strip 113. The external mounting strip 113 is set to serve as an insulating mounting base for the external conductive strips 114, for fixing the external conductive strips 114 inside the external conductive groove 110, and for maintaining electrical insulation between the external conductive strips 114 and the nested groove strips 18. The external conductive strips 114 are used to contact the contacts on the connector when the lightweight electrical connector is inserted into the external conductive groove 110, and to transmit power from the power connector 27 to the electrical equipment. The power connector 27 includes a multi-functional column end structure, which is a modular structure that splits the integrated large plastic connector into a conductive base and four independent power connector blocks. Each power connector block has the same structure, and only one set of molds is needed for mass production, which greatly reduces the mold cost.

[0022] As an embodiment of the present invention, a wire hole 12 is further provided in the middle of the column body 11, and a tapping hole 13 is provided between the inner mounting groove 14 and the inner mounting groove 14. The wire hole 12 facilitates the introduction and guidance of the external power line from one end of the column to the power socket 27.

[0023] As an embodiment of the present invention, the column body 11 is an integral extruded aluminum profile structure. The tapping hole 13 is provided with ribs inside. The tapping hole 13 is provided to facilitate the tapping process at the end of the column body 11. It is used to form a threaded hole at the end of the column body 11 into which a screw can be screwed. After the screw passes through the mounting hole 25 on the end cover 24, it engages with the threaded hole 13, thereby realizing the detachable and fixed connection between the end cover 24 and the end of the column body 11.

[0024] As an embodiment of the present invention, the mounting assembly 2 further includes a mounting flange 21. The mounting flange 21 has a plurality of fixing holes 22 arranged in a circular array on its surface. By setting the mounting flange 21, it is convenient to fix the two ends of the column assembly 1 to the top and bottom of the furniture cabinet or building through the fixing holes 22 and fasteners.

[0025] As an embodiment of the present invention, the mounting flange 21 is further provided with an internal threaded cylinder 23 in the middle, and an external threaded cylinder 26 is threadedly connected inside the internal threaded cylinder 23. The arrangement of the internal threaded cylinder 23 and the external threaded cylinder 26 makes it easy to adjust the relative position of the column body 11 and the mounting flange 21 by rotation, thereby realizing the fine adjustment of the installation height of the device. Moreover, the interior is a hollow structure, which facilitates the passage of power transmission lines.

[0026] As an embodiment of the present invention, the external threaded cylinder 26 is further provided with an end cap 24 at one end, and an installation hole 25 is provided on the surface of the end cap 24. The installation hole 25 coincides with the tapping hole 13. By setting the installation hole 25, it is convenient to fix the end cap 24 to the end of the column body 11, close the opening at the end of the column body 11, and improve the appearance of the device.

[0027] As an embodiment of the present invention, a power connector 27 is further fixedly installed on one end cap 24 away from the external threaded cylinder 26. The power connector 27 is disposed inside the inner mounting groove 14 and the nested groove 18. The power connector 27 is provided to facilitate the electrical connection interface between the external power line and the internal conductive system of the column. It is used to distribute the externally introduced power line to the inner conductive strip 112 and the outer conductive strip 114 via the terminal block 29 and the power contact 28. The power connector 27 also includes a multifunctional terminal block structure inside the column. Through the sliding engagement of the sliding block in the nested groove 18 of the column, the power connector 27 only contacts and conducts with the outer conductive strip 114 when the sliding block is pushed into the conducting position. This realizes independent on-demand power supply for each groove, effectively avoids the risk of electric shock caused by the long-term energization of the exposed outer conductive strip, and improves the safety of use.

[0028] As an embodiment of the present invention, the power base 27 is further provided with a terminal 29 in the middle, and the surface of the power base 27 is provided with a plurality of power contacts 28 that contact the inner conductive strip 112 and the outer conductive strip 114. By providing the terminal 29 and the power contacts 28, it is convenient for the terminal 29 to fix the externally introduced power line to the power base 27, so that the external power is introduced into the power base 27 through the terminal 29, and then distributed to each conductive strip through the power contacts 28.

[0029] In use, the upright body 11 facilitates the bearing of the vertical support load of the entire furniture. The tapping hole 13 serves as a guide for tapping the end of the upright body 11, forming a threaded hole at the end of the upright body 11 into which a screw can be screwed. The screw passes through the mounting hole 25 on the end cap 24 and engages with the threaded hole 13, achieving a detachable and fixed connection between the end cap 24 and the end of the upright body 11. The mounting hole 25 facilitates the fixed installation of the end cap 24 onto the end of the upright body 11, closing the opening at the end of the upright body 11 and improving the aesthetic appearance of the device. The internal threaded cylinder 23 and the external threaded cylinder 26 facilitate the adjustment of the relative position of the upright body 11 and the mounting flange 21 by rotation. The device features a fine-tuned installation height and a hollow internal structure, facilitating the passage of power transmission lines. The junction box 27 serves as an electrical connection interface between the external power supply line and the internal conductive system of the column. It distributes the externally introduced power line to the inner conductive strip 112 and outer conductive strip 114 via the terminal block 29 and contact 28. The terminal block 29 and contact 28 allow for the fixed connection of the externally introduced power line to the junction box 27, enabling external power to be introduced into the junction box 27 via the terminal block 29 and then distributed to the conductive strips via the contact 28. The internal mounting groove 14 accommodates the nested groove 18, junction box 27, and related conductive components, forming an assembly reference space for the functional modules. The space provides a base for insertion and installation of external furniture components such as shelf connectors and clothes rail connectors, integrating the column support function with the power supply function. The inner conductive groove 15 facilitates a deep conductive channel for heavy-duty electrical equipment. The secondary baffle 16 facilitates cooperation with the fixing block 19 of the nested groove 18, enabling the nested groove 18 to be detachably engaged and fixed to the column body 11. Simultaneously, as part of the sliding guide structure for the power terminal, the nested groove 18 is detachably engaged and fixed inside the inner mounting groove 14 through the cooperation of the fixing block 19, secondary baffle 16, and fixing protrusion 17, providing a shallow power channel for light-duty electrical equipment. The nested groove 18 can be installed or removed according to usage requirements. During installation… An outer conductive groove 110 is provided for power supply to light electrical appliances, while an inner conductive groove 15, exposed after removal, is provided for power supply to heavy electrical appliances. This allows for flexible adaptation of the same column to electrical equipment of different power levels. The fixing block 19 facilitates the detachable fixing of the nested groove strip 18 inside the inner mounting groove 14, making installation and removal of the nested groove strip 18 convenient. The outer conductive groove 110 provides a shallow conductive channel for power supply to light electrical equipment, providing a foundation for the installation and power supply of low-power light electrical appliances. The inner mounting strip 111 serves as an insulating mounting base for the inner conductive strip 112, used to fix the inner conductive strip 112 inside the inner conductive groove 15 and maintain electrical insulation between the inner conductive strip 112 and the column body 11.The inner conductive strip 112 is used to contact the contacts on the connector when the heavy-duty electrical connector is inserted into the inner conductive groove 15, transmitting power from the junction box 27 to the electrical equipment. The outer mounting strip 113 serves as an insulating mounting base for the outer conductive strip 114, fixing the outer conductive strip 114 inside the outer conductive groove 110 and maintaining electrical insulation between the outer conductive strip 114 and the nested groove strip 18. The outer conductive strip 114 is used to contact the contacts on the connector when the light-duty electrical connector is inserted into the outer conductive groove 110, transmitting power from the junction box 27 to the electrical equipment.

[0030] refer to Figures 5 to 8 As a further preferred embodiment of the present invention, the power connector 27 includes four independent power connector modules. The four power connector modules have identical structures, requiring only one mold for mass production, significantly reducing mold costs. Each power connector module includes a power connector body 271, power connectors 28, and a sliding block 274. The power connectors 28 include at least two second conductive contacts 281 disposed at the top of the power connector body 271 and two first conductive contacts 282 disposed on both sides of the power connector body 271. The two second conductive contacts 281 are electrically connected to the two first conductive contacts 282, respectively. When any power connector body is inserted into any mounting slot 14, the two first conductive contacts 282 are electrically connected to the inner conductive strips 112 on both sides, respectively.

[0031] The top of the sliding block 274 is provided with two conductive plugs 275, and the main body 271 of the power connector is provided with a insertion hole 276 for the conductive plugs to pass through. The power contact 28 also includes two sets of sliding contacts 283 disposed on the back of the sliding block 274, and the two sets of sliding contacts 283 are electrically connected to the conductive plugs 275 respectively. The two sides of the sliding block 274 are respectively provided with positioning beads to prevent them from falling out of the outer conductive groove 110, and the two sides of the outer conductive groove 110 are provided with positioning grooves 115 that match the positioning beads. When the sliding block is installed in the outer conductive groove 110, the two sets of sliding contacts 283 of the sliding block 274 are electrically contacted with the two outer conductive strips 114 respectively.

[0032] A conductive base 278 for power distribution is provided between the power base 27 and the end cover 24. The conductive base 278 contains a terminal block 29, which includes a first conductive piece 291 and a second conductive piece 292, corresponding to the positive and negative terminals of an external power source, respectively. The first and second conductive pieces respectively form a first conductive contact strip and a second conductive contact strip that meander from the center to the periphery on the end face of the conductive base 278, with the two conductive contact strips spaced apart from each other. Two second conductive contacts 281 and two conductive plugs 275 passing through the insertion hole are electrically connected to the two conductive contact strips. Here, the two conductive contact strips are electrically connected to the second conductive contacts and conductive plugs of four sets of power-connecting modules.

[0033] When the inner mounting slot 14 is not used for heavy electrical equipment, the nested slot strip 18 can be installed as decoration, which can prevent others from accidentally touching the conductive wires and also make the appearance more aesthetically pleasing. When the nested slot strip 18 needs to be connected to electricity, the sliding block 274 slides upward, allowing the conductive plug 275 to be inserted and pass through the plug hole 276 to connect with the two conductive contact strips, thus achieving conductivity. When the nested slot strip 18 is not in use, the sliding block can be slid to any other position on the outer conductive slot 110, and the nested slot strip 18 will not be energized. This achieves independent on-demand power supply for each nested slot strip 18, effectively avoiding the risk of electric shock caused by the exposed outer conductive strip being energized for a long time, and improving the safety of use.

[0034] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
