[0022] The above-mentioned and other technical features and advantages of this utility model will be described in more detail below with reference to the accompanying drawings.

[0023] Example 1

[0024] like Figure 1 and Figure 2 As shown, Figure 1 This is a three-dimensional structural view of the cleaning rack; Figure 2 This is a side view of the structure of the cleaning rack.

[0025] The present invention relates to a cleaning fixture for the interior curtains of a high-speed train, comprising a cleaning frame, the cleaning frame including a curtain baffle 1, a drainage channel 2, and a side panel 3. The curtain baffle 1 is a rectangular plate of appropriate size according to the shape of the high-speed train window frame. The side panels 3 are vertically arranged on both sides of the curtain baffle 1 to form a U-shaped structure, thereby forming a cleaning cavity between the side panels 3. The drainage channel 2 is located at the bottom of the curtain baffle 1.

[0026] In practical use, the drain trough 2 of the cleaning rack is placed downwards on the windowsill, and the curtain baffle 1 is flat against the inner wall of the train window. The curtain in its loaded state is pulled down and enters the cleaning chamber from the upper end of the curtain baffle 1, and is located between the two baffles 3. The curtain is cleaned by spraying neutral detergent and water into the curtain located in the cleaning chamber. Both the baffles 3 and the curtain baffle 1 can prevent the liquid in the cleaning chamber from splashing onto the windowsill or glass. The wastewater generated during cleaning flows into the drain trough 2 under its own gravity and is discharged uniformly, thereby completing the cleaning.

[0027] Preferably, the drain trough 2 is provided with a drain connector 4, which is connected to the water container via a connecting pipe. The drain connector 4 connects the inside of the drain trough 2 and the inside of the water container, thereby facilitating the smooth discharge of sewage from the drain trough 2.

[0028] The cleaning fixture for the interior curtains of the high-speed train described in this utility model also includes a spray bottle, a brush, and a non-woven fabric. The two spray bottles are respectively filled with neutral detergent and water for spraying detergent and water. The brush is used to scrub away stubborn dust on the curtain, and the non-woven fabric is used to wipe the curtain to speed up the natural drying of the curtain after cleaning.

[0029] This invention allows for the cleaning of curtains directly while they are installed on the train, without the need to remove the curtains or replace the entire structure. This greatly improves work efficiency and saves on material costs, while also enhancing the quality of the train's interior facilities and ensuring the high-standard, high-quality operation of the high-speed train.

[0030] Example 2

[0031] The bottom of the curtain baffle 1 is fixedly provided with two side plates 21 and a bottom plate. The two side plates 21 are arranged in parallel. Both sides of the bottom plate are fixedly and sealed to the side plates 21 to form the drainage groove 2. The groove opening of the drainage groove 2 faces the curtain baffle 1. The bottom plate includes an end plate section 22 and a groove bottom section 23. The two end plate sections 22 are located at both ends of the groove bottom section 23. The end plate sections 22 extend in an arc from the horizontal direction to the vertical direction to form an arc plate-shaped structure. The arc-shaped end plate sections 22 can avoid interference between the bottom plate and the car window sill, which is more conducive to the placement of the washing rack on the car window sill and ensures that the curtain baffle 1 can be tightly fitted to the inner wall of the train window glass.

[0032] Preferably, one of the side panels 21 and the curtain baffle 1 are disposed on the same plane and fixedly welded to the bottom of the curtain baffle 1, and the drain connector 4 is disposed on the other side panel 21 to ensure a tight fit between the curtain baffle 1 and the inner wall of the train window glass.

[0033] like Figure 3 As shown, Figure 3 This is a structural view of the drainage trough; preferably, the drainage connector 4 is located at one end of the side plate 21 and at the lower part of the side plate 21. The bottom surface of the end plate section 22 is horizontal and the top surface is inclined. The thickness of the end plate section 22 gradually decreases along the direction close to the drainage connector 4, thereby ensuring that the sewage in the drainage trough 2 can be collected and discharged to the lowest drainage connector 4.

[0034] Generally, the cross-sectional area of ​​the drain connector 4 gradually decreases in the direction away from the side plate 21 to form a conical connector, thereby facilitating the quick insertion and removal of the end of the connecting pipe from the drain connector 4.

[0035] Both the base plate and the outer wall of the edge plate 3 are provided with rubber strips 5, which serve as a protective buffer to prevent the cleaning rack from colliding with the windowsill or scratching when adjusting the position of the cleaning rack, thus preventing the cleaning rack from damaging the windowsill components.

[0036] Example 3

[0037] The edge plate 3 is also provided with a locking component, which can fix the position of the washing rack on the windowsill.

[0038] like Figure 4 As shown, Figure 4 This is a structural view of the locking assembly; specifically, the two locking assemblies are symmetrically arranged on the two side plates 3. Each locking assembly includes a locking bolt 6 and a locking nut 7. The locking bolt 6 and the locking nut 7 are threaded together. The locking nut 7 is welded and fixed to the side plate 3 and is disposed inside the cleaning chamber. The side plate 3 is provided with a locking hole corresponding to the locking nut 7. The locking hole is a through hole, and the end of the locking bolt 6 passes through the locking hole and extends out of the cleaning chamber.

[0039] By rotating the adjustable locking bolt 6 to extend beyond the cleaning chamber, the locking bolt 6 can be pressed against the two side walls of the inner frame of the train window, thereby locking the cleaning rack in position on the windowsill.

[0040] Generally, curtain cord grooves are provided on both sides of the inner frame of the EMU window. The end of the locking bolt 6 can be placed in the curtain cord groove to lock the locking bolt 6 in the position of the EMU window. The width of the curtain cord groove is larger than the size of the locking bolt 6, which facilitates the connection between the locking bolt 6 and the curtain cord groove.

[0041] Preferably, the end of the locking bolt 6 is provided with a first rubber sleeve 8, the first rubber sleeve 8 is provided with a first sleeve hole, the first sleeve hole is not through, the end of the locking bolt 6 extending from the cleaning chamber is provided in the first sleeve hole, and the locking bolt 6 is in contact with the EMU window frame through the first rubber sleeve 8 to avoid scratching and damaging the inner frame of the EMU window.

[0042] Preferably, the end of the locking bolt 6 is further provided with a second rubber sleeve 9, the second rubber sleeve 9 is provided with a second sleeve hole, the second sleeve hole is not through, the cross-sectional shape of the second sleeve hole is polygonal corresponding to the bolt head of the locking bolt 6 or the locking nut 7, the bolt head of the locking bolt 6 and the locking nut 7 are both provided in the second sleeve hole, so as to be sleeved on the bolt head position of the locking bolt 6 after the cleaning rack is fixed, so as to avoid the bolt head of the locking bolt 6 and the locking nut 7 from scratching and damaging the curtain.

[0043] The above description is merely a preferred embodiment of the present utility model and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present utility model, all of which will fall within the protection scope of the present utility model.
