Detailed implementation mode

[0025] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variants.

[0026] As Figures 1 to 6 shown, a wiring structure of a household elevator includes a top plate 20 fixedly connected to an indoor ceiling or a fixed plane above. The bottom surface of the top plate 20 is fixedly connected with parallel inner columns 2. An outer column 5 that can move up and down along the outer peripheral surface of the inner column 2 is arranged on the outer periphery of the inner column 2. A placement plate is connected between the two outer columns 5 for placing kitchen small appliances or other items; the placement plate can be one layer or multiple layers. Among them, the top plate 20 has a cavity, the inner column 2 has an inner column wire threading cavity 12, and the outer column has an outer column wire threading cavity 14. The cavity of the top plate 20, the inner column wire threading cavity 12 and the outer column wire threading cavity 14 are communicated to facilitate accommodating the wiring path of the wire harness 6; a controller 15 is fixedly installed in the cavity of the top plate 20. The controller 15 has a power cord 1 connected to the indoor power supply. The power cord 1 is connected to the indoor power supply. The controller 15 is also connected to the wire harness 6. After the controller 15 is powered on by the power cord 1, it can supply power to the power socket 4; a power socket 4 is arranged on the surface of one side of the outer column 5 facing the placement plate. The fixed position 17 of the front end of the wire harness of the wire harness is electrically connected to the controller 15, and the other end extends downward, passes through the inner column wire threading cavity 12 of the inner column and forms a U-shaped bend 16 in the outer column wire threading cavity 14 of the outer column and then is connected to the power socket 4 to realize the connection of the power supply line. Among them, the downward extension section of the wire harness 6 is regarded as the downward path, and the upward extension section after the U-shaped bend 16 is regarded as the upward path. As the outer column 5 moves up and down, the position of the U-shaped bend 16 in the outer column wire threading cavity 14 of the outer column moves up or down to realize the adjustment of the length of the wire harness 6, and it can be used regardless of whether the household elevator moves up or down.

[0027] Specifically, an upper bearing seat 7 is further arranged in the cavity of the top plate 20. The upper bearing seat 7 is fixedly connected with a wire protection sleeve 8, and a wire pressing block A9 is buckled on the upper surface of the wire protection sleeve 8. One end of the wire harness 6 extends from the controller 15, passes through the wire protection sleeve 8 and the upper bearing seat 7, and then extends into the wire threading cavity 12 of the inner column. Then, the wire pressing block A9 is fixed to the wire protection sleeve 8 through a screw A10 to prevent the end position of the wire harness 6 from changing and keep the circuit regular.

[0028] In this embodiment, an upper end cover 3 of the outer column is installed on the top surface of the outer column 5, and the installation position of the power socket 4 is close to the upper end cover 3 of the outer column; the upward path section of the wire harness 6 forms a bend after passing through the upper end cover 3 of the outer column, and the wire harness end fixing part 18 is connected to the power socket 4. In order to position this bend and prevent disconnection from the power socket 4 during the lifting and lowering of the household elevator, the wire pressing block B11 fixes the bent section of the wire harness 6 to the upper end cover 3 of the outer column through a screw B13, realizing the fixation of the bent section.

[0029] Working principle: When the household elevator descends, the section of the wire harness from the front end fixing part 17 to the lower end wire outlet of the inner column 2, that is, the downward path, remains stationary in the wire threading cavity 12 of the inner column. The U-shaped bend 16 and the wire harness end fixing part 18 follow the outer column 5 to descend. The distance between the wire harness end fixing part 18 and the lower end wire outlet 19 of the inner column becomes shorter. When the household elevator descends by a height of M, the U-shaped bend 16 descends by a height of half of M; when ascending, the distance between the wire harness end fixing part 18 and the lower end wire outlet 19 of the inner column becomes longer, and the U-shaped bend 16 also follows to ascend, releasing the required length. Thus, when the socket power supply 4 ascends and descends, the wire harness 6 can change its length in real time to meet the requirements.

[0030] When the controller 15 receives a descending signal, the household elevator starts to descend. After descending in place, the controller 15 starts to energize the wire harness 6, and the current is transmitted through the wire harness 6 to the power socket 4, and various electrical appliances connected to the power socket 4 enter the powered and operable state; when the controller 15 receives an ascending signal, the controller synchronously disconnects the power supply of the wire harness 6.

[0031] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
