Description

Technical Field

[0001] The present invention relates to the technical field of rail transit equipment, and in particular to a toilet sliding door and a rail vehicle toilet. Background Art

[0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] The toilets of rail vehicles are usually equipped with sliding doors for easy opening. However, there are still some problems with the existing sliding door structure, such as: the door panel protective skirting board is easy to fall off in the humid environment of the toilet; the door panel vibrates when the vehicle is running at high speed; the ventilation effect and personnel privacy are relatively poor when the toilet door is closed.

[0004] CN108974027A discloses a double-leaf linkage sliding door device for a railway passenger car toilet, the main structure of which includes a side frame, a lower guide rail, an upper guide rail, a mounting plate, an outer door panel, an inner door panel, an outer connecting plate, an inner connecting plate, a skirting board, a sliding strip, etc. The outer door panel and the inner door panel of the scheme are attached with a skirting board of a rectangular sheet structure at the bottom. Since the skirting board is an adhesive structure, there is still a problem that the skirting board is easy to fall off due to the internal humid environment. Moreover, the above scheme is suitable for toilets with relatively large spaces to solve the problem of door panel opening, but there will also be chattering during the operation of the vehicle, affecting the passengers' experience of the journey.

[0005] CN214007002U discloses a bathroom door that is convenient for ventilation, including a door panel and a door frame. The top and bottom of the front of the door panel are both provided with ventilation windows. Two installation cavities are provided on the back of the door panel. A ventilation fan is fixedly connected inside the installation cavity. The ventilation window is inclined at 45 degrees. The existing bathroom door is ventilated by opening air holes, but the ventilation is slow and the privacy is insufficient. Although the solution solves the problem of insufficient privacy by using the ventilation window set at an angle, the ventilation window needs to be ventilated with the ventilation fan. The ventilation fan is installed on the door panel, which increases the thickness of the door panel. Moreover, the vibration of the door panel will increase when the ventilation fan is working, so it is not suitable for rail vehicles. Summary of the invention

[0006] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a toilet sliding door and a rail vehicle toilet, which can ensure that the door panel runs without rattling during the high-speed operation of the vehicle; the skirting board is not easy to fall off in the humid environment of the toilet; and when the toilet door is closed, the ventilation effect and privacy are guaranteed.

[0031] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0032] Embodiment 1:

[0033] This embodiment provides a bathroom sliding door, such as Figure 1As shown, it includes a door panel 1 and a door frame 2, the door frame 2 is installed with an upper slide rail 3 and a lower slide rail 4, the top of the door panel 1 is slidably connected to the upper slide rail 3, and the bottom is slidably connected to the lower slide rail 4, and the door panel 1 can be opened or closed by pushing the handle on the door panel 1.

[0034] The upper, lower, inner and outer parts of this embodiment are based on the installation state of the door panel 1; Figure 1 As shown, the top of the door panel 1 is slidably connected to the upper slide rail 3 through a plurality of slide blocks (for example, two), and the bottom of the door panel 1 is matched with the lower slide rail 4 through a lower slide groove 9.

[0035] In order to avoid the problem of the door panel 1 vibrating during high-speed operation of the vehicle, the lower slide groove 9 of this embodiment adopts a segmented structure. By controlling the size range of the lower slide groove 9 in segments, the door panel can be operated smoothly without vibrating.

[0036] Preferably, by setting the length segments at both ends of the lower slide groove 9 and strictly controlling the dimensions, it is effectively ensured that there is no chattering when the door panel is in the closed state; the lower slide groove 9 is divided into a middle section, a first section at one end of the middle section, and a second section at the other end of the middle section, and by setting the cross-sectional width of the middle section (the gap width of the lower slide groove 9) to be slightly looser than the dimensions of the other two sections, it is ensured that the door panel runs smoothly.

[0037] In this embodiment, the cross section of the lower slide groove 9 is inverted U-shaped, and the gap width of the lower slide groove 9 refers to the width of the bottom opening of the lower slide groove 9; Figure 2 and Figure 3 As shown, the bottom opening of the lower slide groove 9 is curved inward to form a stable fit with the slide rail.

[0038] like Figure 1 As shown, the length of the middle section of the sliding groove 9 is greater than the first section and the second section at the two ends, and the lengths of the first section and the second section are equal. By controlling the gap size in the equal length range at the two ends of the sliding groove 9, the purpose of no chattering is achieved.

[0039] like Figure 2 As shown, the gap in the middle section of the lower slide groove 9 is L (0.3, 0.5) mm. Figure 3 As shown, the gap between the first section and the second section is L (0.2, 0.3) mm. Figure 4 As shown, the size of the guide column of the lower slide rail is positioned at L(-0.2, -0.1) mm. The door panel 1 that meets the three requirements cooperates with the lower slide rail 4 to ensure that the door panel runs smoothly without chattering.

[0040] For example, when the lengths of the first and second sections of the lower slide groove 9 are 100 mm, the gap between the first and second sections is 8 (0.2, 0.3) mm, and the gap between the middle section is 8 (0.3, 0.5) mm.

[0041] After the sliding door is installed, the installation error is strictly controlled, and the distance between the lower surface of the door panel 1 and the installation surface of the lower slide rail 4 is 6 (-0.5, 1.5) mm, for example, to ensure the contact surface between the door panel 1 and the lower slide rail 4 to prevent the door panel 1 from sliding off the track.

[0042] An inner skirting board 5 is fixed to the inner side of the door panel 1 , and an outer skirting board 6 is fixed to the outer side. Both the inner skirting board 5 and the outer skirting board 6 are located at the lower part of the door panel 1 , and are respectively arranged on both sides of the lower sliding groove 9 .

[0043] like Figure 2 As shown, since the inner skirting board 5 corresponds to the inner side of the door panel 1, it is more likely to fall off due to a humid environment. Therefore, the inner skirting board 5 of this embodiment is adhered to the inner surface of the door panel 1 by glue and fixed by studs 7; the studs 7 are arranged in multiple rows and columns, and the studs 7 are perpendicular to the door panel 1, and the inner skirting board 5 is further reinforced by the studs 7.

[0044] The stud 7 of this embodiment has a threaded hole inside, and the screw 8 is fastened into the stud 7 from the outside of the door panel 1 to effectively fix the inner skirting board 5 and reduce the skirting board from falling off in a humid environment. After the inner skirting board 5 is fixed, the outer skirting board 6 is pasted on the outside of the door panel 1 to strengthen the fixation of the inner skirting board 5 and ensure the appearance.

[0045] The studs 7 and the screws 8 form a connecting piece for connecting the inner skirting board 5 and the door panel 1 .

[0046] The inner skirting board 5 and the outer skirting board 6 of the present embodiment are arranged on both sides of the lower slide groove 9, and cooperate with the segmented structure of the lower slide groove 9 to ensure that there is no vibration when the door panel 1 is closed, reduce the shaking of the door panel 1, make the inner skirting board 5 and the outer skirting board 6 more firmly combined with the door panel 1, and make the skirting board less likely to fall off.

[0047] In order to ensure the privacy of the bathroom, the door panel 1 is installed with an inclined ventilation grille 10, which can be installed at the upper position or the upper position of the door panel 1, or the ventilation grille 10 can be installed at both the upper position and the upper position of the door panel 1.

[0048] like Figure 5 As shown, for the ventilation grille 10 arranged at the upper position of the door panel 1, the ventilation grille 10 is inclined upward from the outside to the inside of the door panel 1. The inclined structure ensures ventilation of the bathroom and the passage platform. At the same time, people in the bathroom cannot be seen from the outside, ensuring privacy.

[0049] The ventilation grille 10 is composed of a plurality of grille plates spaced vertically, and a ventilation channel 11 is formed between adjacent grille plates. In this embodiment, the grille plates are sequentially provided with inclined sections and arc sections from the inside to the outside of the door panel 1, and a gradually expanding (variable cross-section) channel structure is formed between adjacent grille plates, that is, the outer opening of the channel 11 is larger than the inner opening, thereby enhancing the ventilation effect.

[0050] In this embodiment, no additional ventilation device is needed, and the ventilation requirements can be met by the arrangement of the ventilation grilles 10 .

[0051] This embodiment optimizes the structure of the door panel skirting board, which can effectively reduce the shedding of the skirting board in a humid environment; optimizes the structure of the sliding groove under the door panel to ensure the smooth operation of the bathroom sliding door and no rattle when the door is closed; and optimizes the structure of the door panel ventilation grille to ensure good ventilation and high privacy.
