[0060] The first mounting seat 10 and the second mounting seat 20 are connected by a connecting structure.

[0061] The pipeline installation structure is hinged to the first mounting seat 10 and the second mounting seat 20 respectively, and is used to fix pipelines and lines.

[0062] The telescopic structure 40 includes a first sliding kit 41 connected to the first mounting seat 10 and a second sliding kit 42 connected to the second mounting seat 20. The first sliding kit 41 and the second sliding kit 42 are slidably connected, and an installation space for pipeline installation is formed on the telescopic structure 40.

[0063] like Figure 1As shown, in this embodiment, the first mounting seat 10 includes:

[0064] The first fixed seat 11 is used for fixed connection with the first component. The first fixed seat 11 is provided with a fixed connection part. Preferably, the fixed connection part is constructed as a plate-like structure, including a plurality of through holes, and can be fixedly connected to the first component by connecting members such as bolts. The fixed connection part is provided with a rotating connection part for hinged connection with the first rotating seat 12.

[0065] The first mounting seat 10 also includes a first rotating seat 12, which is hinged to the first fixed seat 11. The first rotating seat 12 includes a main body, which is configured as a narrow and long plate-like structure, and a first rotating base 121 is provided on one side thereof to cooperate with the rotating connection part on the first fixed seat 11. Preferably, a rib is provided between the first rotating base 121 and the main body to increase the strength of the main body. The first rotating base 121 and the rotating connection part are rotatably connected by a rotating shaft, so that the first rotating seat 12 can rotate relative to the first fixed seat 11. Preferably, in this embodiment, two first fixed seats 11 are provided, and the two first fixed seats 11 are arranged at a certain distance, and the two first fixed seats 11 are arranged up and down in the vertical direction; correspondingly, two first rotating bases 121 are provided on the first rotating seat 12, and the two first fixed seats 11 and the two first rotating bases 121 correspond to each other to form two pairs of rotating cooperation. Further, the two pairs of rotating cooperation are connected by a connecting shaft to facilitate assembly.

[0066] like Figure 7 As shown, the first rotating seat 12 also includes: a first hinged portion 122 connected to the connecting rod structure 30, the first hinged portion 122 is hinged to one end of the connecting rod structure 30, and the first hinged portion 122 is at the upper end of the main body, preferably including two supporting portions, the two supporting portions are arranged oppositely and spaced a certain distance apart, and hinge holes are arranged at the ends of the two supporting portions, and the axes of the two hinge holes are collinear, and the end of the connecting rod structure 30 extends between the two supporting portions, and is inserted through the two hinge holes and the connecting rod structure 30 through a pin shaft and other structures to achieve hinge connection.

[0068] Preferably, when multiple telescopic parts are provided, other mounting parts may be provided on the main body between the first hinge part 122 and the first fixing part 123 for mounting more telescopic structures 40 or other structures.

[0069] The second mounting seat 20 comprises:

[0070] A second fixing seat 21, used for fixedly connecting with the second component;

[0071] The second rotating seat 22 is hinged to the second fixed seat 21.

[0072] The second rotating seat 22 has the same structure as the first rotating seat 12, and includes: a main body, on which is provided a second hinged portion 222 connected to the connecting rod structure 30, the second hinged portion 222 is hinged to one end of the connecting rod structure 30; and / or, a second fixed portion 223 connected to the second portion 42, the second fixed portion 223 is provided with a through hole communicating with the installation space. A second rotating base 221 is also provided on the main body, and the second rotating base 221 is used to be rotatably connected to the second fixed seat 21.

[0073] In this embodiment, the structure of the second fixed seat 21 is the same as that of the first fixed seat 11, or, part of the structure of the second fixed seat 21 may be partially different from that of the first fixed seat 11 according to the requirement of its cooperation with the second component, but the functions of the corresponding parts are the same; the second rotating seat 22 has the same structure as the first rotating seat 12, and the specific structure of the second mounting seat 20 will not be described in detail here.

[0074] Preferably, if Figure 1 , Figure 2 As shown, the telescopic tube 50 is also included. The telescopic tube 50 is arranged in the installation space. The end of the telescopic tube 50 is connected to the first pipe joint 111. The telescopic tube 50 is preferably a corrugated tube, which can be connected to the water inlet or drain pipe. Alternatively, the corrugated tube is used as a protective tube and is sleeved on the outside of part of the pipe to protect the pipe. In this case, it is not part of the waterway and does not need to be connected to the first pipe joint 111 on the first fixing seat 11.

[0075] Specifically, Figure 3 , Figure 4 As shown, the connecting rod structure 30 includes at least two connecting rods hinged to each other. The length of the connecting rod structure 30 can be changed by rotating the connecting rods. In this embodiment, the connecting rod structure 30 includes three connecting rods, namely:

[0076] A first connecting rod 31, a first end of the first connecting rod 31 is hinged to the first mounting seat 10;

[0077] A second connecting rod 32, a first end of the second connecting rod 32 is hinged to the second end of the first connecting rod 31;

[0078] The third connecting rod 33, the first end of the third connecting rod 33 is hinged to the second end of the second connecting rod 32, and the second end of the third connecting rod 33 is hinged to the second mounting seat 20; preferably, the first connecting rod 31, the second connecting rod 32 and the third connecting rod 33 are connected by a rotating shaft, and both ends of the first connecting rod 31, the second connecting rod 32 and the third connecting rod 33 are provided with hinge holes, and the hinge between the two connecting rods is realized by passing the rotating shaft, the connecting pin and other structures through the two hinge holes. The first connecting rod 31 and the third connecting rod 33 are hinged at both ends of the second connecting rod 32, and the first connecting rod 31 and the third connecting rod 33 form an angle with the second connecting rod 32, and the size of the angle can be changed with the relative movement of the first mounting seat 10 and the second mounting seat 20, so as to realize the telescopic length of the entire connecting rod structure 30. Preferably, in other embodiments, the connecting rod structure 30 can also be provided with more connecting rods, such as four connecting rods, five connecting rods, etc., which can be set as needed.

[0079] Alternatively, the connecting rod structure 30 may be replaced by a structure similar to the connecting rod structure 30. For example, the connecting rod structure 30 may be replaced by a drag chain structure, and a connecting cavity for setting up a pipeline or line is formed inside the drag chain structure.

[0080] In this embodiment, a fixing structure is provided on the first connecting rod 31 and / or the second connecting rod 32 and / or the third connecting rod 33, and the fixing structure is used to fix the pipeline and / or the line. Preferably, the fixing structure is provided on the three connecting rods at the same time to make the fixation of the pipeline and / or the line more reliable and enable the pipeline and / or the line to be arranged along the connecting rod structure 30.

[0081] Preferably, the fixing structure includes a first clamping structure for fixing the line, and / or a second clamping structure for fixing the pipeline. In this embodiment, the first clamping structure and the second clamping structure are provided at the same time.

[0082] Furthermore, the first connecting rod 31, the second connecting rod 32 and the third connecting rod 33 are constructed as a plate-like structure. The connecting rod structure 30 formed by connecting the three includes a first mounting surface and a second mounting surface. A first clamping structure is formed on the first mounting surface for fixing circuits, such as power supply and control circuits, etc.; a second clamping structure is formed on the second mounting surface for fixing pipelines, such as water inlet and drainage pipelines, etc. The first clamping structure and the second clamping structure are respectively formed on two surfaces of the connecting rod structure 30 to separate the waterway and the circuit to avoid mutual influence between water and electricity.

[0083] like Figure 3 As shown, the first clamping structure preferably includes a high-voltage clamping structure 301 for fixing the power supply line, and a low-voltage clamping structure 302 for fixing the control line, so as to achieve separation of high-voltage and low-voltage, make the line layout neater, and avoid mutual interference between high-voltage and low-voltage.

[0084] The second clamping structure includes a water pipe clamping groove for clamping the water pipe. The water pipe clamping groove is preferably provided on the first connecting rod 31, the second connecting rod 32 and the third connecting rod 33 at the same time, so that the water pipe can be arranged along the connecting rod structure 30. In this embodiment, an anti-freezing cracking structure 34 is provided on the waterway, and the anti-freezing cracking structure 34 is connected to the waterway as a part of the waterway. Preferably, the second connecting rod 32 is located at the low point of the connecting rod structure 30, and the anti-freezing cracking structure 34 is provided on the second connecting rod. The water pipe is divided into two parts, which are clamped on the first connecting rod 31 and the second connecting rod 32 respectively, and then connected to the anti-freezing cracking structure 34 at the same time.

[0085] like Figure 4 As shown, when the anti-freeze cracking structure 34 is provided, the water pipe slot does not need to be provided on the second connecting rod 32. Further, in order to cooperate with the installation of the anti-freeze cracking structure 34, a first water pipe slot 304 is provided on the first connecting rod 31 near its first end, and a second water pipe slot 303 is provided near its second end (near the position of the second connecting rod 32). The anti-freeze cracking structure 34 is located at the lower side of the second connecting rod 32, and the second water pipe slot 303 is formed to protrude toward the lower side of the first connecting rod 31, so as to facilitate the pipeline 60 to pass through the second water pipe slot 303 and connect with the anti-freeze cracking structure 34. In this embodiment, the third connecting rod 33 and the first connecting rod 31 form a symmetrical structure, which are symmetrically provided at both ends of the second connecting rod 32.

[0086] like Figure 5 , Figure 6 As shown, preferably, the anti-freeze cracking structure 34 includes a water flow channel 341, which is connected to the water circuit for water circulation. Preferably, the water flow channel 341 is a tubular structure arranged along the extension direction of the second connecting rod 32, and its two ends are respectively used to communicate with the pipeline 60.

[0087] The antifreeze structure also includes an air cavity 342, which is located on the upper side of the water flow channel 341 and is connected to the water flow channel 341 through a connecting hole 343. Preferably, the connecting hole 343 has a small aperture. When water flows in the water flow channel 341, the water flow will block the connecting hole 343, and because there is air in the exhaust cavity 342, water will not enter the exhaust cavity 342; when the ambient temperature decreases, the air in the air cavity 342 contracts, and the water in the water flow channel 341 expands when it freezes, and a part of it enters the air cavity 342 through the connecting hole 343, thereby preventing the expansion of the frozen water volume from causing the pipeline to rupture. Since the antifreeze cracking structure 34 is located at the lowest point of the pipeline, a small amount of water remaining in the pipeline will remain in the water flow channel 341 of the antifreeze cracking structure 34, preventing the freezing from affecting the entire pipeline.

[0088] Preferably, if Figure 7As shown, in this embodiment, the telescopic structure 40 can also be constructed as a sleeve assembly, that is, the first sliding kit 41 and the second sliding kit 42 are both constructed as a cylindrical structure, which are put together and can slide relative to each other. Among them, the first sliding kit 41 and the second sliding kit 42 can be formed integrally with the first mounting seat 10 and the second mounting seat 20 respectively to simplify the assembly process. Further, a guide structure is arranged in the axial direction on the first sliding kit 41 and the second sliding kit 42, for example, the radial dimension of the first sliding kit 41 is smaller than the radial dimension of the second sliding kit 42, the first sliding kit 41 extends into the second sliding kit 42, a groove is formed on the outer peripheral wall of the first sliding kit 41 along its axial direction, and a protrusion is arranged on the inner peripheral wall of the corresponding second sliding kit 42 along its axial direction, the protrusion extends into the groove and can slide with each other, and guides the sliding of the first sliding kit 41 and the second sliding kit 42, preferably, two grooves and two protrusions are arranged; it is easy to think that a protrusion can also be arranged on the outer peripheral wall of the first sliding kit 41, and a groove can be arranged on the inner peripheral wall of the second sliding kit 42.

[0089] Alternatively, two or more telescopic structures 40 may be provided at the same time to facilitate the installation of different pipelines or lines. For example, two telescopic structures 40 may be provided, and the two telescopic structures 40 may adopt different structures or the same structure. Of course, more telescopic structures 40 may be provided as needed.

[0090] In another embodiment, if Figure 8 As shown, the telescopic structure 40 includes a plurality of first sliding rods 411 connected to the first mounting seat 10, and a first sliding ring 412 connected to the first sliding rods 411. Preferably, the plurality of first sliding rods 411 are evenly distributed along the same circumference, the first ends of the plurality of first sliding rods 411 are fixedly connected to the first mounting seat 10, and the second ends of the plurality of first sliding rods 411 are circumferentially distributed and connected to the first sliding ring 412.

[0091] The telescopic structure 40 also includes a plurality of second sliding rods 421 connected to the second mounting seat 20, and a second sliding ring 422 connected to the second sliding rods 421. Preferably, the plurality of second sliding rods 421 are evenly distributed along the same circumference, the first ends of the plurality of second sliding rods 421 are fixedly connected to the second mounting seat 20, and the second ends of the plurality of second sliding rods 421 are circumferentially distributed and connected to the second sliding ring 422.

[0092] The first slip ring 412 is slidably mounted on the second slide bar 421, and the second slip ring 422 is slidably mounted on the first slide bar 411. The first slip ring 412 is located between the second slip ring 422 and the second mounting seat 20, and the second slip ring 422 is located between the first slip ring 412 and the first mounting seat 10. The first slip ring 412 and the second slip ring 422 are mutually limited, and the spaces between the plurality of first slide bars 411 and the plurality of second slide bars 421 together constitute the installation space. The first slip ring 412 and the second slip ring 422 slide relative to each other, changing the length of the telescopic structure 40, that is, changing the length of the installation space, and the first slip ring 412 and the second slip ring 422 are mutually limited.

[0093] The present invention also provides a clothes processing device, such as Fig. 9 As shown, including:

[0094] Frame 2, frame 2 is provided with a plurality of processing barrel installation positions for installing clothing processing barrels;

[0095] The clothes treatment bucket includes a drawer-type treatment bucket 1, which is slidably connected to a frame 2 and can be drawn out from the frame 2 for putting in or collecting clothes, or pushed into the frame 2. The drawer-type treatment bucket 1 constitutes a first component, the frame 2 constitutes a second component, and the above-mentioned variable-stroke pipeline bearing structure is arranged between the first component and the second component, that is, the variable-stroke pipeline bearing structure is connected between the drawer-type treatment bucket 1 and the frame 2.

[0096] The first mounting seat 10 is installed on the drawer-type processing barrel 1, and the second mounting seat 20 is installed on the frame 2. The drawer-type processing barrel 1 is pulled out from the front side of the frame 2, and the second mounting seat 20 is installed on the rear side of the frame 2. When the drawer-type processing barrel 1 is pulled out or pushed, the pipeline bearing structure with variable stroke follows its movement to extend or contract it as a whole.

[0097] Preferably, the first mounting seat 10 is installed on the first side of the frame 2, and the second mounting seat 20 is installed on the second side on the back of the drawer-type treatment barrel 1. The first side and the second side are arranged diagonally opposite to each other, so that the pipeline installation structure is obliquely arranged between the frame and the drawer-type treatment barrel, that is, the pipeline installation structure is obliquely arranged along the diagonal in the space between the drawer-type treatment barrel 1 and the frame 2.

[0098] Specifically, in this embodiment, the first mounting seat 10 is installed on the left edge of the drawer-type processing bucket 1, and the second mounting seat 20 is installed on the right edge of the drawer-type processing bucket 1.
