[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1

[0023] See also Figures 1 to 3 , which is the first embodiment of the present utility model, and provides a technical solution: the bottom traction mechanism of the super large sliding door includes

[0024] The traction base 1 is fixed to the bottom surface of the sliding door panel 8 by bolts, a rectangular slot 12 is opened on the top surface of the traction base 1, a rope seat 2 is inserted into the rectangular slot 12, a traction rope 3 is fixed on the top surface of the rope seat 2, and a traction wheel 4 is sleeved on the driving shaft 5 and located at the top end of the sliding door panel 8. The top end of the traction rope 3 is fixed on the traction wheel 4. Subsequently, the driving shaft 5 rotates the traction wheel 4 under the drive of the external driving motor, and the traction wheel 4 will reel in the traction rope 3. In this process, the traction rope 3 will pull the rope seat 2 and the traction base 1 upward to achieve the upward traction of the sliding door panel 8, thereby gradually pulling the sliding door panel 8 open. When the sliding door panel 8 moves up and down, the guide wheels on both sides of the sliding door panel 8 will slide in the curved guide rails installed on the inner side of the door frame 9 to ensure the stable lifting of the sliding door panel 8. The guide wheel and the curved guide rail are auxiliary structures of the sliding door itself and have nothing to do with the traction mechanism of this application. Therefore, they are not marked in the drawings and are recorded separately.

[0025] And a quick plug-in mechanism, including a T-shaped pin 6, a T-shaped socket 11 provided on the front surface of the traction base 1, a pin hole 21 provided on the surface of the rope seat 2, and a limit pressure seat 7 movably installed on the front surface of the traction base 1 and covering the T-shaped socket 11, which can play a stable blocking and limiting role for the T-shaped pin 6 inserted into the T-shaped socket 11, ensuring the plug-in stability of the traction base 1 and the rope seat 2. The T-shaped pin 6 is inserted into the T-shaped socket 11, and the rear end of the T-shaped pin 6 passes through the pin hole 21, realizing the plug-in between the traction base 1 and the rope seat 2, and quickly The quick plug-in mechanism also includes an inner slide groove 13 opened inside the bottom end of the traction base 1, an inner slider 14 and a spring 15 installed in the inner slide groove 13, and a pull rod 16 welded and fixed to the front surface of the inner slider 14. The front end of the pull rod 16 passes through the front surface of the traction base 1 and is rotatably connected to the bottom end of the limit pressure seat 7 through a rotating shaft. Under the push of the spring 15, the limit pressure seat 7 can be stably pressed on the front surface of the traction base 1 during daily use, ensuring the compression and limitation of the T-shaped pin 6, and ensuring the plug-in stability between the rope seat 2 and the traction base 1.

[0026] The front end of the spring 15 abuts against the inner wall of the inner sliding groove 13 , and the rear end of the spring 15 abuts against the front surface of the inner sliding block 14 .

[0027] The front end surface of the T-shaped latch 6 is welded with a strip pin seat 61, and the surface of the limiting pressure seat 7 is provided with a strip limiting groove 71 corresponding to the strip pin seat 61. The strip pin seat 61 is embedded in the strip limiting groove 71, so that the limiting pressure seat 7 will not rotate during daily use, ensuring the pressing stability of the T-shaped latch 6. Later, if the rope seat 2 is to be separated from the traction base 1, it is only necessary to pull the limiting pressure seat 7 forward with force so that the pull rod 16 pulls the inner slider 14 and the spring 15 is gradually compressed, so that the limiting pressure seat 7 gradually moves forward until the strip pin seat 61 is completely moved out of the strip limiting groove 71. At this time, the limiting pressure seat 7 can be rotated, thereby rotating and removing the limiting pressure seat 7 from the T-shaped socket 11, and no longer blocking the T-shaped latch 6. The strip pin seat 61 can be pinched and the T-shaped latch 6 can be pulled out from the pin hole 21, so that the rope seat 2 is no longer restricted. Then the rope seat 2 can be easily disassembled from the traction base 1, and the rope seat 2 and the traction base 1 can be quickly disassembled. When the two are assembled later, the bottom end of the rope seat 2 is first inserted into the rectangular slot 12, and then the T-shaped latch 6 is inserted into the T-shaped socket 11, and the rear end of the T-shaped latch 6 is inserted into the pin hole 21, and then the limiting pressure seat 7 is pulled forward and rotated back to the T-shaped socket 11, and then the limiting pressure seat 7 is released, so that the spring 15 pushes the inner slider 14 back and presses the limiting pressure seat 7 on the T-shaped socket 11 to block and limit the T-shaped latch 6, and at the same time, the strip pin seat 61 is stuck in the strip limiting groove 71, and the rapid assembly of the traction base 1 and the rope seat 2 is completed.

[0028] Example 2

[0029] See also Figures 1 to 4 , which is the second embodiment of the present invention, is based on the previous embodiment, but differs in that the positioning structure can be provided to play an auxiliary positioning role when the T-shaped pin 6 is inserted into the pin hole 21.

[0030] Specifically, the quick plug-in mechanism also includes a positioning structure, which is arranged between the T-shaped pin 6 and the pin hole 21. The positioning structure includes a rubber seat 22 embedded in the upper wall of the pin hole 21, a positioning protrusion 23 arranged on the bottom surface of the rubber seat 22, and two positioning slots 62 opened on the surface of the T-shaped pin 6. The positioning protrusion 23 is embedded in one of the positioning slots 62. When the rear end of the T-shaped pin 6 is inserted into the pin hole 21, the positioning protrusion 23 will be squeezed into one of the positioning slots 62, thereby realizing auxiliary positioning of the T-shaped pin 6 at this time, preventing the T-shaped pin 6 from slipping from the T-shaped socket 11 at this time, and facilitating further compression and limiting by the limiting pressure seat 7.

[0031] The rubber seat 22 and the positioning protrusion 23 are an integrated structure. Both are made of rubber material and will undergo elastic deformation when squeezed. A rectangular cavity is provided in the rubber seat 22, so that the positioning protrusion 23 has sufficient deformation space when squeezed.

[0032] Although embodiments of the present invention have been shown and described (see the detailed description above for details), it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
