Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the utility model.

[0027] In the description of the present invention, descriptions of orientations, such as up, down, front, back, left, right, etc., and orientations or positional relationships indicated are based on the orientations or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0028] It will be understood that when one element (eg, a first element) is “connected” to another element (eg, a second element), the element may be directly connected to the other element or an intervening element (eg, a third element) may be present between the element and the other element.

[0029] The embodiment of the utility model provides an ultra-high heavy-duty folding door, such as Figure 1-6 As shown, it includes an upper guide rail seat 100, a lower guide rail seat 200 and a plurality of door bodies 300, the upper guide rail seat 100 is located above the lower guide rail seat 200 and is arranged parallel to the lower guide rail seat 200, the door body 300 is arranged between the upper guide rail seat 100 and the lower guide rail seat 200, the upper end of the door body 300 is slidingly connected to the upper guide rail seat 100, the lower end of the door body 300 is slidingly connected to the lower guide rail seat 200, the door bodies 300 are distributed along the sliding direction, and adjacent door bodies 300 are rotationally connected, thereby, when the door body 300 slides along the guide rail seat, the adjacent door bodies 300 can be relatively rotated and folded to form a folding door.

[0030] An upper slide groove 101 is arranged in the upper guide rail seat 100, and an upper slot 102 connected to the upper slide groove 101 is arranged on the bottom surface of the upper guide rail seat 100. Two sets of hanging wheels 110 are slidably connected in the upper slide groove 101. The two sets of hanging wheels 110 are respectively located on both sides of the slot 102 so that the two sets of hanging wheels 110 are evenly stressed. The axes of the two sets of hanging wheels 110 are parallel to the horizontal direction. The hanging wheels 110 rotate around the horizontal direction. The upper connecting rod 301 is fixed to the top of the door body 300, and the upper connecting rod 301 passes through the upper slot 102 and extends into the upper slot 101. Both sets of hanging wheels 110 are rotatably connected with the upper connecting rod 301. When the hanging wheel 110 rotates, the upper connecting rod 301 slides in the upper slot 101 and the upper slot 102, which correspondingly drives the upper end of the door body 300 to slide along the upper guide rail seat 100.

[0031] A lower groove 201 is provided in the lower guide rail seat 200, and a lower slot 202 connected to the lower groove 201 is provided on the top surface of the lower guide rail seat 200. A guide wheel 210 is slidably connected in the lower groove 201. The axial direction of the guide wheel 210 is parallel to the vertical direction. The guide wheel 210 mainly plays an auxiliary guiding role and basically does not bear the weight of the door body 300. A lower connecting rod 302 is fixed to the bottom of the door body 300. The lower connecting rod 302 passes through the lower slot 202 and extends into the lower groove 201. The guide wheel 210 is rotatably connected to the lower connecting rod 302. When the guide wheel 210 rotates, the lower connecting rod 302 slides in the lower groove 201 and the lower slot 202, and correspondingly drives the lower end of the door body 300 to slide along the lower guide rail seat 200. The upper end of the door body 300 of the present embodiment forms a hanging structure, and the weight of the door body 300 is mainly borne on the upper guide rail seat 100 through the hanging wheel 110. The axial direction of the guide wheel 210 in the lower guide rail seat 200 is parallel to the vertical direction, and mainly plays a role in assisting sliding. This hanging structure can reduce the force on the lower guide rail seat 200. Since the door body 300 is relatively high, when the user pushes and pulls the door body 300, the force is mainly applied to the lower end of the door body 300. The lower end of the door body 300 is relatively smoother, which can improve the smoothness of the folding door, making it more labor-saving to push and pull, thereby improving the user experience.

[0032] In some embodiments, the door body 300 includes a door panel 310 and a door frame 320 sleeved on the outer periphery of the door panel 310, the upper connecting rod 301 and the lower connecting rod 302 are fixed on the door frame 320, and the door frames 320 of adjacent door bodies 300 are rotatably connected. The door panel 310 of this embodiment can be a glass plate, so that the fixing of the upper connecting rod 301 and the lower connecting rod 302 and the rotatable connection of adjacent door bodies 300 will not groove or open holes on the door panel 310, so as not to damage the door panel 310, thereby ensuring the integrity and structural strength of the door panel 310.

[0033] The door frames 320 of two adjacent door bodies 300 can be rotatably connected via hinges 303 .

[0034] Furthermore, a clamping assembly is provided at the top of the inner side of the door frame 320 (the side close to the door panel 310) and the bottom of the inner side of the door frame 320. The clamping assembly includes a front stopper 400 and a rear stopper 500. The front stopper 400 is integrally connected with the door frame 320 to facilitate overall manufacturing. The rear stopper 500 is fixed to the door frame 320 later. The front stopper 400 is located at the front side of the door panel 310, and the rear stopper 500 is located at the rear side of the door panel 310. The front stopper 400 and the rear stopper 500 clamp the door panel 310, thereby limiting the movement of the door panel 310 relative to the door frame 320, so as to stably fix the door panel 310. Since the rear baffle assembly 500 is fixed to the door frame 320 at a later stage, when installing the door panel 310, the front side of the door panel 310 is firstly abutted against the front baffle 400, and then the rear baffle assembly 500 is fixed to the door frame 320, and the rear baffle assembly 500 is abutted against the rear side of the door panel 310, thereby facilitating the installation of the door panel 310.

[0035] Furthermore, the rear baffle assembly 500 includes a connecting member 510 and a rear baffle 520. The inner side of the door frame 320 is provided with a buckle groove 304. The connecting member 510 is hooked in the buckle groove 304. The rear baffle 520 is snap-connected with the connecting member 510. The front baffle 400 and the rear baffle 520 clamp the door panel 310. The entire rear baffle assembly 500 can be composed of two main parts. When installing, the connecting member 510 is first hooked in the buckle groove 304, and then the rear baffle 520 is fixed to the connecting member 510, so as to facilitate the installation of the rear baffle assembly 500.

[0036] Furthermore, Figure 6As shown, the connecting member 510 is provided with a protrusion 513 protruding toward the door panel, the rear side of the protrusion 513 is provided with a first buckle groove 511 extending transversely, and the inner side of the connecting member 510 (the side close to the door panel) is provided with a second buckle groove 512, and the second buckle groove 512 is located at the rear side of the first buckle groove 511. The rear stopper 520 includes a first clamping member 521, a second clamping member 522 and abutting member 523 arranged in sequence from front to back. When installing the rear stopper 520, the rear stopper 520 can be laterally approached to the connecting member 510 from the rear side of the protrusion 513, the first clamping member 521 is laterally inserted into the first buckle groove 511, the second clamping member 522 is buckled in the second buckle groove 512, the abutting member 523 abuts against the door frame 320, and the front end of the rear stopper 520 abuts against the door panel, which makes the installation of the rear stopper 520 easier.

[0037] In some embodiments, the connector 510 is provided with two hooks 514, which are respectively hooked on the inner wall of the front side of the buckle slot 304 and the inner wall of the rear side of the buckle slot 304. The connector 510 is fixed by the two hooks 514 to improve its fixing stability.

[0038] In some embodiments, a plurality of wear-resistant seals 600 are fixed to the top and bottom of the door frame 320. The wear-resistant seal 600 at the top of the door frame 320 abuts against the upper guide rail seat 100, and the wear-resistant seal 600 at the bottom of the door frame 320 abuts against the lower guide rail seat 200. When the door body 300 slides, the wear-resistant seal 600 slides relative to the guide rail seat and remains abutted against the guide rail seat, thereby improving the sealing between the door frame 320 and the upper guide rail seat 100 and between the door frame 320 and the lower guide rail seat 200.

[0039] The terms and words used in the above description and claims are not limited to the literal meanings, but are only used by the applicant to enable a clear and consistent understanding of the utility model. Therefore, it should be clear to those skilled in the art that the above description of various embodiments of the utility model is provided only for illustration, and not for limiting the utility model as defined by the attached claims and their equivalents.
