[0032] This invention discloses a double-layer sliding door, such as... Figure 1 As shown, the disclosed double-layer sliding door includes a door frame (not shown in the figure), a door body assembly, and a transmission mechanism 300. The door body assembly is slidably connected to the door frame, and the transmission mechanism 300 is connected to the door body assembly. Specifically, the door body assembly includes a first door body 110 and a second door body 120, and the transmission mechanism 300 is connected to the first door body 110 and the second door body 120. When the first door body 110 opens and closes under the action of an external force, the transmission mechanism 300 drives the second door body 120 to synchronously open and close, and the direction of linkage of the second door body 120 is the same as the direction of movement of the first door body 110.

[0033] In the embodiments disclosed in this invention, the bottom frame of the door frame is provided with a single-layer guide rail 410, and the bottom of the door assembly is provided with a roller assembly that matches the guide rail 410.

[0034] Furthermore, the door assembly can be located inside the guide rail 410, and a baffle can be provided between the door assembly and the guide rail 410. For example... Figures 2 to 5 As shown, the roller assembly may include a first roller 411 and a second roller 412. A first roller 411 is provided at each of the bottom ends of the first door body 110, and a second roller 412 is provided at each of the bottom ends of the second door body 120. The first roller 411 can be connected to the first door body 110 via a grooved connector 130, and similarly, the second roller 412 can also be connected to the second door body 120 via a grooved connector 130.

[0035] Specifically, one protruding end of the groove-shaped connector 130 is fixed to the bottom of the second door body 120, and a second roller 412 is provided on the inner side of the other protruding end. The second roller 412 rolls on the guide rail 410 provided in the groove of the groove-shaped connector 130 to achieve a sliding connection between the second door body 120 and the bottom of the door frame. The second side 112 of the first door body 110 is at least partially provided on the inner side of the second door body 120, and the first roller 411 provided at the bottom of the second side 112 is located between the two second rollers 412. Similarly, the first roller 411 can also be connected to the bottom of the second side 112 through the groove-shaped connector 130. The groove of the groove-shaped connector 130 is not only provided with the guide rail 410, but also with a fitting gap between the first door body 110 and the second door body 120. Of course, the bottom of the first side 111 of the first door body 110 is also connected to another first roller 411 through a groove-shaped connector 130 with a guide rail 410 in the groove.

[0036] The double-layer sliding door disclosed in this embodiment adopts a single-track roller sliding structure at the bottom of the door assembly. The ingenious design of the double-door rollers crossing each other can reduce the number of double-track sliding components at the bottom of ordinary double-layer doors, effectively reduce costs, and completely eliminate the problems of multiple tracks being prone to dust accumulation, difficult to clean, and easily damaged, thereby improving the service life of the sliding door.

[0037] Of course, the embodiments of the present invention do not impose specific limitations on the number of rollers at the bottom of the first door body 110 or the second door body 120.

[0038] In the embodiments disclosed in this invention, the transmission mechanism 300 may include a transmission roller 310, a first traction rope 321 and a second traction rope 322. The transmission roller 310 is disposed on a grooved connector 130 that connects to the second roller 412, specifically disposed on the outside of the protruding end of the grooved connector 130 that connects to the second roller 412.

[0039] It should be noted that, due to the cross arrangement of the double door rollers, the second roller 412 is located on the second side 112 of the first door body 110.

[0040] The transmission roller 310 can be a double-groove roller, such as... Figure 4 , Figure 5 As shown, one end of the first traction rope 321 is fixed to one end of the bottom frame of the door frame via the first fixing seat 331; the first traction rope 321 is disposed in one of the slots of the double-groove roller, passes around the double-groove roller, and is fixed to the outside of the protruding end of the grooved connector 130 at the bottom of the first side 111 of the first door body 110 via the second fixing seat 332. When the first door body 110 moves toward the first side 111, the first traction rope 321 drives the double-groove roller to rotate and move, further driving the second door body 120 connected to the double-groove roller to move synchronously and in the same direction.

[0041] like Figures 2 to 4 As shown, one end of the second traction rope 322 is fixed to the other end of the bottom frame of the door frame via the fourth fixing seat 334; the second traction rope 322 is disposed in another groove of the double-groove roller, passes around the double-groove roller, and is fixed to the outside of the protruding end of the groove-shaped connector 130 at the bottom of the second side 112 of the first door body 110 via the third fixing seat 333. It should be noted that the groove-shaped connector 130 is connected to the first door body 110. When the first door body 110 moves toward the second side 112, the second traction rope 322 drives the double-groove roller to rotate and move, further driving the second door body 120 connected to the double-groove roller to move synchronously and in the same direction.

[0042] The double-layer sliding door disclosed in this embodiment achieves the synchronous opening and closing movement of the two door bodies through a structural design of two traction ropes and double-groove rollers for bidirectional traction, thereby improving the stability of the synchronous opening and closing movement of the two door bodies.

[0043] Furthermore, the first fixing seat 331 and / or the second fixing seat 332 and / or the third fixing seat 333 and / or the fourth fixing seat 334 may also be provided with adjusting members for adjusting the tension of the first traction rope 321 or the second traction rope 322.

[0044] Preferably, the first traction rope 321 and / or the second traction rope 322 can be stainless steel wire ropes.

[0045] In the embodiments disclosed in this invention, such as Figure 6 As shown, the disclosed double-layer sliding door may further include a guide member 200, which is disposed on the top frame of the door frame and serves to support and guide the top of the door assembly. Figure 7 As shown, the guide member 200 may include three guide plates installed along the top frame. The three guide plates are fixed together by several connecting components, and a first guide groove 210 and a second guide groove 220 are respectively provided between two adjacent guide plates. A first upright plate is provided on the top of the first door body 110, and the end of the first upright plate opposite to the first door body 110 is disposed in the first guide groove 210 and is clearance-fitted with the first guide groove 210. A second upright plate is provided on the top of the second door body 120, and the end of the second upright plate opposite to the second door body 120 is disposed in the second guide groove 220 and is clearance-fitted with the second guide groove 220.

[0046] It should be noted that the embodiments of the present invention are not limited to the simultaneous opening and closing of two-layer doors, but can be the simultaneous opening and closing of multiple-layer doors. As long as the transmission mechanism described in any of the above embodiments is provided between each pair of adjacent door layers, the simultaneous opening and closing of multiple-layer doors can be achieved.

[0047] Secondly, embodiments of the present invention also disclose a machine tool, wherein the disclosed machine tool adopts the double-layer sliding door described in any of the above embodiments.

[0048] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
