[0023] See Figures 1 to 4The present invention discloses a wire structure for a telescopic shelf 200, comprising: a cabinet 100, wherein the cabinet 100 has a forward-opening cavity 110, and a guide groove 120 extending along the depth direction of the cavity 110 is provided on the left or right side wall of the cabinet 100; a telescopic shelf 200, slidably disposed in the cabinet 100, capable of extending or retracting along the opening of the cavity 110, wherein an electrical unit 600 is provided on the front side of the telescopic shelf 200, and a strip-shaped groove 201 opposite to the guide groove 120 is recessed on the left or right side of the telescopic shelf 200; and a protective cable chain 300. Both ends are fixed within the guide groove 120 and the strip groove 201, respectively. A wire channel 301 extending along the length direction is provided through the middle of the protective drag chain 300. The protective drag chain 300 includes a first chain segment 310 arranged along the guide groove 120, a second chain segment 320 arranged along the strip groove 201, and a corner segment 330 connecting the first chain segment 310 and the second chain segment 320. An electric wire 400 is passed through the wire channel 301, with one end extending to the front side of the telescopic shelf 200 to connect to the electrical unit 600, and the other end connected to the power supply terminal inside the cabinet 100.

[0024] The wire structure of the telescopic shelf 200 described above utilizes a protective drag chain 300 to cover the outside of the wire 400. The wire 400 passes through the wiring channel 301 to connect the power supply terminal of the cabinet 100 and the electrical unit 600, thus concealing the wire 400 for an aesthetically pleasing effect. Moreover, the wire 400 can move smoothly back and forth with the telescopic shelf 200, preventing the wire 400 from being pulled and getting stuck. The first chain segment 310 is located within the guide groove 120, and the second chain segment 320 is located within the strip groove 201. This avoids increasing the width of the cabinet 100 to accommodate the wire structure of the telescopic shelf 200. The protective drag chain 300, composed of the first chain segment 310, the corner segment 330, and the second chain segment 320, is also known as a tank chain. When the telescopic shelf 200 extends, the first chain segment 310 shortens, the second chain segment 320 extends, and the corner segment 330 moves forward. When the telescopic shelf 200 retracts, the first chain segment 310 extends, the second chain segment 320 shortens, and the corner segment 330 moves backward. The wire 400 moves and deforms with the protective drag chain 300, preventing excessive slack or knotting.

[0025] See Figure 3 and Figure 4In some embodiments of this utility model, the protective cable chain 300 includes multiple links pivotally connected in sequence. A through hole is provided through the middle of each link, and the multiple through holes are sequentially connected to form the wiring channel 301. One end of the wire 400 extends from the end of the first chain segment 310 and is connected to a first power terminal 410. The power supply end of the cabinet 100 is connected to a second power terminal 130 extending from the inner wall of the cabinet 100. The first power terminal 410 and the second power terminal 130 are detachably plugged in. It is understood that the links of the protective cable chain 300 can rotate relative to each other to pass through the corner segment 330, and the first chain segment 310 and the second chain segment 320 always remain parallel. The first power terminal 410 and the second power terminal 130 are plugged in together for easy assembly, and the first power terminal 410 and the second power terminal 130 are separated for easy maintenance or replacement of the telescopic shelf 200.

[0026] See Figure 3 In some embodiments of this utility model, in order to avoid the electrical unit 600 being exposed, the front side of the telescopic shelf 200 is provided with a strip-shaped placement cavity 211 for accommodating the electrical unit 600. In order to avoid exposing part of the wire 400 as much as possible, the end of the strip-shaped placement cavity 211 is provided with an inlet that is connected to the second chain segment 320. The wire 400 extends along the guide groove 120, the strip-shaped groove 201, the inlet and the strip-shaped placement cavity 211 in sequence, thereby achieving complete concealment of the wire 400.

[0027] See Figure 2 and Figure 3 In some embodiments of this utility model, the telescopic shelf 200 has a front crossbeam 210 on its front side. A housing 500 with an opening facing the front sidewall of the front crossbeam 210 is mounted on the front crossbeam 210. The cable inlet is located at the end of the housing 500 and on the front crossbeam 210. The front crossbeam 210 closes the opening of the housing 500 to define the strip-shaped placement cavity 211. The electrical unit 600 is a display module or a touch module. The front sidewall of the housing 500 has a window for exposing the electrical unit 600. The housing 500 and the front crossbeam 210 are two independent components. By assembling them, the strip-shaped placement cavity 211 and the cable inlet can be formed, which is more advantageous for the installation and electrical connection of the electrical unit 600 and reduces the difficulty of production and processing.

[0028] See Figure 3 and Figure 4In some embodiments of this utility model, a notch 510 is provided through the end of the housing 500 along the length of the front crossbeam 210. The notch 510 has an opening facing the front sidewall of the front crossbeam 210. A wire-passing hole 212 is provided through the front crossbeam 210, connecting the end of the strip groove 201 with the opening of the notch 510. The wire-passing hole 212 and the notch 510 constitute the wire inlet. It should be noted that after one end of the wire 400 extends out of the strip groove 201, it can be inserted into the strip cavity 211 from the side of one end of the front crossbeam 210. Then, the housing 500 can be installed and fixed, and the wire 400 can be constrained in the wire inlet.

[0029] See Figure 4 In some embodiments of this utility model, the inner diameter of the wire-passing hole 212 is slightly larger than the outer diameter of the wire 400, and the end face of the front crossbeam 210 is provided with a narrow opening communicating with the wire-passing hole 212. The width of the narrow opening is slightly smaller than the outer diameter of the wire 400. It is understood that, to avoid threading and reduce assembly difficulty, the user can apply pressure from the side of the wire 400 to allow it to recover its elastic deformation after entering the wire-passing hole 212 through the narrow opening, thereby preventing the wire 400 from falling off the end of the front crossbeam 210.

[0030] See Figure 1 and Figure 4 In some embodiments of this utility model, the telescopic shelf 200 further includes a rear crossbeam 220, a left crossbeam 230, and a right crossbeam 240. The front crossbeam 210, the rear crossbeam 220, the left crossbeam 230, and the right crossbeam 240 form a rectangular frame. Multiple parallel, spaced-apart support crossbeams 250 connect the front crossbeam 210 and the rear crossbeam 220. Each support crossbeam 250 has multiple spaced-apart limiting grooves 251 along its length. The limiting grooves 251 at the same position on each support crossbeam 250 can collectively support the wine bottle, facilitating the vertical flow of cold air and achieving a good refrigeration effect. It should be noted that, generally speaking, the length of the electrical unit 600, which serves as the display module or touch module, is smaller than the length of the front crossbeam 210, and the material of the housing 500 is different from that of the rectangular frame. To improve the aesthetics of the telescopic shelf 200, see [reference needed]. Figures 2 to 4 In some embodiments of this utility model, the length of the box body 500 is smaller than the length of the front crossbeam 210. Decorative strips 700 are provided between one end of the box body 500 and the left crossbeam 230, and between the other end of the box body 500 and the right crossbeam 240. The front surface of the decorative strips 700 is flush with the front surface of the box body 500.

[0031] See Figure 3 and Figure 4 In some embodiments of this utility model, the decorative strip 700 has a guide slope 710 at one end facing the box body 500, and a dovetail groove is defined between two decorative strips 700. The outer contour of the box body 500 matches the dovetail groove. The front crossbeam 210, the rear crossbeam 220, the left crossbeam 230, the right crossbeam 240, and the decorative strips 700 are all made of wood. The box body 500 is connected to the front crossbeam 210 by self-tapping screws. It should be noted that the front crossbeam 210, the rear crossbeam 220, the left crossbeam 230, the right crossbeam 240, and the decorative strips 700 can be fixed together with screws and / or glue. The way the box body 500 is embedded in the dovetail groove can prevent the box body 500 from detaching forward from the front crossbeam 210, thus limiting the position of the box body 500.

[0032] This utility model also discloses an electrical device, including the wire structure of the telescopic shelf 200 of any of the above technical solutions. The wire 400 passes through the wiring channel 301 to connect the power supply terminal of the cabinet 100 and the electrical unit 600, thereby hiding the wire 400 for an aesthetic effect. Moreover, the wire 400 can move smoothly back and forth with the telescopic shelf 200, avoiding the wire 400 from being pulled and getting stuck.

[0033] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0034] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
