[0038] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0039] According to some embodiments of this utility model, refer to Figures 1 to 8The tri-fold door includes a door frame 100, a door panel assembly 200, and a linkage assembly 300. The door frame 100 has an opening 101. The door panel assembly 200 includes a first door panel 210, a second door panel 220, and a third door panel 230. The first and second door panels 210 and 220 are slidably connected to the door frame 100 in the left-right direction, and the third door panel 230 is fixedly connected to the door frame 100. The opening 101 is located on the left side of the third door panel 230. (See reference...) Figures 2 to 5 The linkage component 300 includes a first rack 310, a second rack 320, and a gear 330. Both the first rack 310 and the second rack 320 extend in the left-right direction. The first rack 310 is fixedly installed on the first door panel 210, and the second rack 320 is fixedly installed on the door frame 100. The gear 330 meshes with both the first rack 310 and the second rack 320, and is rotatably connected to the second door panel 220. When the first door panel 210 moves in the left-right direction, the gear 330 rotates relative to the first rack 310 and the second rack 320, causing the second door panel 220 to move in the left-right direction. The first door panel 210 and the second door panel 220 can work together to block or open the opening 101.

[0040] Understandably, when the first door panel 210 slides to the right, the first rack 310 moves to the right along with the first door panel 210, thereby driving the gear 330 to rotate. During the rotation of the gear 330, it moves to the right relative to the second rack 320, thus driving the second door panel 220 to move to the right, causing the second door panel 220 to slide to the right along with the first door panel 210. Similarly, when the first door panel 210 slides to the left, the first rack 310 moves to the left along with the first door panel 210, thereby driving the gear 330 to rotate. During the rotation of the gear 330, it moves to the left relative to the second rack 320, thus driving the second door panel 220 to move to the left, causing the second door panel 220 to slide to the left along with the first door panel 210. Figure 7 In this configuration, the first door panel 210 and the second door panel 220 work together to seal the opening 101. Figure 8 In the middle, the first door panel 210 drives the second door panel 220 to move to the right, so that the opening 101 is opened.

[0041] It should be noted that since the second rack 320 is fixed, the first rack 310 moves in the left and right direction, thereby driving the gear 330 to rotate. The speed of the center of the gear 330 in the left and right direction is half that of the first rack 310, that is, the stroke of the first door panel 210 is twice that of the second door panel 220.

[0042] The first door panel 210 and the second door panel 220 of the tri-fold door move synchronously and in the same direction, making it easier and faster to open and close the door.

[0043] According to some embodiments of this utility model, refer to Figure 4 and Figure 5The door frame 100 is provided with a first guide strip 110, which extends in the left-right direction. A first connector 241 is fixedly provided at the upper end of the first door panel 210. A first rack 310 is fixedly installed on the first connector 241. A first guide wheel 242 is rotatably connected to the first connector 241. The axis of the first guide wheel 242 is in the front-back direction. The first guide wheel 242 and the first guide strip 110 are connected to each other so that the first guide wheel 242 can move along the extension direction of the first guide strip 110. The first guide strip 110 can guide the movement of the first guide wheel 242 to prevent the first door panel 210 from deviating.

[0044] Preferred, refer to Figure 5 The outer peripheral wall of the first guide wheel 242 is provided with a first annular groove 243. The first guide strip 110 is partially inserted into the first annular groove 243. The first guide strip 110 supports the first guide wheel 242 and thus supports the first door panel 210. The groove wall of the first annular groove 243 can abut against the front and rear sides of the first guide strip 110 to prevent the first guide wheel 242 from disengaging from the first annular groove 243.

[0045] According to some embodiments of this utility model, refer to Figure 4 and Figure 5 The door frame 100 is provided with a second guide strip 120, which extends in the left-right direction. A second connector 251 is fixedly provided at the upper end of the second door panel 220. A gear 330 is rotatably connected to the second connector 251, with the axis of the gear 330 pointing up and down. A second guide wheel 252 is rotatably connected to the second connector 251, with the axis of the second guide wheel 252 pointing forward and backward. The second guide wheel 252 cooperates with the second guide strip 120, allowing the second guide wheel 252 to move along the extension direction of the second guide strip 120. The second guide strip 120 guides the movement of the second guide wheel 252, thereby preventing the second door panel 220 from deviating.

[0046] Preferred, refer to Figure 5 The outer peripheral wall of the second guide wheel 252 is provided with a second annular groove 253. The second guide bar 120 is partially inserted into the second annular groove 253. The second guide bar 120 supports the second guide wheel 252, thereby supporting the second door panel 220. The groove wall of the second annular groove 253 can abut against the front and rear sides of the second guide bar 120 to prevent the second guide wheel 252 from disengaging from the second annular groove 253.

[0047] According to some embodiments of this utility model, refer to Figure 1 and Figure 4 The first door panel 210 is equipped with handles 260 on both the front and rear sides, making it convenient for users to push and pull the first door panel 210 using the handles 260.

[0048] According to some embodiments of this utility model, refer to Figure 6 The door frame 100 is provided with a first guide groove 130, which extends in the left-right direction. The lower end of the first door panel 210 is inserted into and slidably connected to the first guide groove 130. A first roller 271 is rotatably connected to the lower end of the first door panel 210. The axis of the first roller 271 is in the up-down direction. The first roller 271 is located within the first guide groove 130, and its outer peripheral wall abuts against the groove wall of the first guide groove 130. The first roller 271 can roll relative to the first guide groove 130, thereby reducing the friction between the first door panel 210 and the first guide groove 130. At the same time, the first guide groove 130 can restrict the movement of the first door panel 210 in the front-back direction, thereby preventing the first door panel 210 from deviating.

[0049] According to some embodiments of this utility model, refer to Figure 6 The door frame 100 is provided with a second guide groove 140, which extends in the left-right direction. A second roller 272 is rotatably connected to the lower end of the second door panel 220. The axis of the second roller 272 is in the up-down direction. The second roller 272 is located within the second guide groove 140, and its outer peripheral wall abuts against the groove wall of the second guide groove 140. The second roller 272 can roll relative to the second guide groove 140, thereby reducing the friction between the second door panel 220 and the second guide groove 140. At the same time, the second guide groove 140 can restrict the movement of the second door panel 220 in the front-back direction, thereby preventing the second door panel 220 from deviating.
