[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1 - Figure 6 This utility model provides a technical solution: a tightly connected elevator guide rail structure, comprising:

[0031] The first elevator guide rail 100 and the second elevator guide rail 200 are provided with a T-shaped connecting block 300 at one end, and a T-shaped connecting groove 400 adapted to the T-shaped connecting block 300 is provided at the other end of the first elevator guide rail 100 and the second elevator guide rail 200.

[0032] A connecting assembly 500 is used to connect the first elevator guide rail 100 and the second elevator guide rail 200. The connecting assembly 500 includes a first fixing block 501 and a second fixing block 502 respectively fixed to the back of the first elevator guide rail 100 and the second elevator guide rail 200. A plug-in block 503 is fixed to the end of the surface of the second fixing block 502, and a plug-in hole 504 adapted to the plug-in block 503 is opened on the surface of the first fixing block 501. A rectangular... The rectangular cavity 505 has two symmetrical movable plates 506 slidably disposed on its inner wall. Three locking blocks 507 are fixedly disposed at equal intervals on the surface of each of the two movable plates 506. The inner wall of the rectangular cavity 505 has a rectangular hole for the locking blocks 507 to slide. The inner wall of the insertion hole 504 has a locking groove 508 adapted to the locking blocks 507. The connecting assembly 500 also includes a rotating disk 509 disposed at the end of the insertion block 503 for driving the two movable plates 506 to move towards each other.

[0033] See Figure 4 The inner wall of the rectangular cavity 505 is rotatably provided with a rotating rod 5010 extending to the outer surface of the plug block 503. The rotating disk 509 is fixed at the end of the rotating rod 5010, and the surface of the rotating disk 509 is provided with a hexagonal operating groove.

[0034] Specifically, by setting a hexagonal operating groove, it is easy to rotate the rotating disk 509 by using an external hexagonal wrench, thereby driving the rotating rod 5010 to rotate automatically.

[0035] See Figure 4 The inner walls on both sides of the rectangular cavity 505 are provided with two symmetrical threaded pillars 5011, and the surfaces of the two movable plates 506 are provided with threaded holes that are threaded to the outer surface of the threaded pillars 5011.

[0036] Specifically, by setting the threaded post 5011, the rotation of the threaded post 5011 can drive the moving plate 506 to move.

[0037] See Figure 4 The surface of the rotating rod 5010 is fixed with a first bevel gear 5012 corresponding to the two threaded posts 5011, and the ends of the two threaded posts 5011 are fixed with a second bevel gear 5013 that meshes with the first bevel gear 5012.

[0038] Specifically, by setting the first bevel gear 5012 and the second bevel gear 5013, the rotation of the rotating rod 5010 can drive the two first bevel gears 5012 to rotate, thereby driving the four second bevel gears 5013 and the four threaded columns 5011 to rotate simultaneously.

[0039] In this invention, by setting a connecting component 500, when connecting two adjacent elevator guide rails, the first elevator guide rail 100 can be inserted into the T-shaped connecting groove 400 on the second elevator guide rail 200 through the T-shaped connecting block 300, and the insertion block 503 on the second fixing block 502 can be inserted into the insertion hole 504 on the first fixing block 501. Then, by rotating the rotating disk 509 with a hex wrench, the rotation of the rotating disk 509 drives the rotating rod 5010 to rotate, and the rotation of the rotating rod 5010 drives... The rotation of the two first bevel gears 5012 drives the rotation of the four second bevel gears 5013 and the threaded column 5011, thereby causing the two moving plates 506 to move to both sides simultaneously. This allows the locking block 507 on the moving plate 506 to be inserted into the locking groove 508 on the inner wall of the insertion hole 504, thus achieving rapid fixing of the first fixing block 501 and the second fixing block 502, thereby achieving rapid and tight connection and fixing of the first elevator guide rail 100 and the second elevator guide rail 200.

[0040] See Figure 5 and Figure 6 The first fixing block 501 is provided with a limiting component 600. The limiting component 600 includes a cavity opened inside the first fixing block 501 and a sliding plate 601 slidably disposed on the inner wall of the cavity. A limiting block 602 is fixed on the surface of the sliding plate 601.

[0041] Specifically, by setting the limiting component 600, the T-shaped connecting block 300 inserted into the T-shaped connecting slot 400 can be effectively limited.

[0042] See Figure 6 The inner wall of the cavity is provided with a limiting hole 603 that extends into the T-shaped connecting groove 400 and is slidably connected to the surface of the limiting block 602. The surface of the T-shaped connecting block 300 is provided with a limiting groove 604 that is adapted to the limiting block 602.

[0043] Specifically, by setting a limiting hole 603 and a limiting groove 604, the limiting block 602 can pass through the limiting hole 603 and be inserted into the limiting groove 604, thereby achieving effective limiting and fixing of the T-shaped connecting block 300.

[0044] See Figure 6 The other end of the rotating rod 5010 extends into the cavity and is fixedly provided with a first bevel gear 605. A lead screw 606 is rotatably provided on the inner wall of the cavity. A second bevel gear 607 that meshes with the first bevel gear 605 is fixedly provided on the surface of the lead screw 606. A limiting rod 608 is fixedly provided on the inner wall of the cavity. The surface of the sliding plate 601 is provided with a through hole that is slidably connected to the surface of the limiting rod 608 and a threaded hole that is threadedly connected to the surface of the lead screw 606.

[0045] Specifically, by setting the first bevel gear 605 and the second bevel gear 607, the rotation of the rotating rod 5010 can drive the lead screw 606 to rotate, thereby driving the sliding plate 601 to move automatically through the rotation of the lead screw 606.

[0046] In this invention, by setting a limiting component 600, the first bevel gear 605 can be driven to rotate during the rotation of the rotating rod 5010. The rotation of the first bevel gear 605 drives the second bevel gear 607 and the lead screw 606 to rotate. The rotation of the lead screw 606 drives the sliding plate 601 to move, so that the limiting block 602 on the surface of the sliding plate 601 passes through the limiting hole 603 and is inserted into the T-shaped connecting groove 400 on the T-shaped connecting block 300, thereby effectively limiting the T-shaped connecting block 300, and thus effectively limiting and reinforcing the first elevator guide rail 100 and the second elevator guide rail 200 after connection.

[0047] Working principle: When connecting two adjacent elevator guide rails, the first elevator guide rail 100 is inserted into the T-shaped connecting groove 400 on the second elevator guide rail 200 via the T-shaped connecting block 300, and the insertion block 503 on the second fixing block 502 is inserted into the insertion hole 504 on the first fixing block 501. Then, the rotating disk 509 is rotated by a hex wrench. The rotation of the rotating disk 509 drives the rotating rod 5010 to rotate, which in turn drives the two first bevel gears 5012 to rotate. The rotation of the two first bevel gears 5012 drives the four second bevel gears 5013 and the threaded post 5011 to rotate, thereby driving the two moving plates 506 to move to both sides simultaneously, so that the locking block 507 on the moving plate 506 is inserted into the insertion hole 504. Within the locking groove 508 on the inner wall of 04, the first fixing block 501 and the second fixing block 502 are quickly fixed, thereby achieving a quick and tight connection and fixation between the first elevator guide rail 100 and the second elevator guide rail 200. Moreover, during the rotation of the rotating rod 5010, it can drive the first bevel gear 605 to rotate. The rotation of the first bevel gear 605 drives the second bevel gear 607 and the lead screw 606 to rotate. The rotation of the lead screw 606 drives the sliding plate 601 to move, so that the limiting block 602 on the surface of the sliding plate 601 passes through the limiting hole 603 and is inserted into the T-shaped connecting groove 400 on the T-shaped connecting block 300, thereby effectively limiting the T-shaped connecting block 300, and thus effectively limiting and reinforcing the first elevator guide rail 100 and the second elevator guide rail 200 after connection.

[0048] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
