DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example: Figure 1-3As shown, the utility model provides a high-strength elevator guide rail, including a first elevator guide rail body 1 and a second elevator guide rail body 2. Guide buffer mechanisms 3 are symmetrically fixedly arranged on both sides of the connection between the first elevator guide rail body 1 and the second elevator guide rail body 2. The guide buffer mechanism 3 guides and buffers the connection between the first elevator guide rail body 1 and the second elevator guide rail body 2, thereby improving the splicing efficiency of the first elevator guide rail body 1 and the second elevator guide rail body 2.

[0020] The guide buffer mechanism 3 includes a U-shaped fixing block 4, which is fixedly matched with one end of the first elevator guide rail body 1 close to the second elevator guide rail body 2 through a fixing bolt 5, and a connecting rod 6 is fixedly provided on the side of the U-shaped fixing block 4 away from the first elevator guide rail body 1.

[0021] By adopting the above technical solution, when the fixing bolt 5 is tightened, the U-shaped fixing block 4 is fixed to the first elevator guide rail body 1 located below, so as to guide the installation of the second elevator guide rail body 2.

[0022] A U-shaped mounting bar 8 is fixedly provided at one end of the rotating rod 7 away from the connecting rod 6 , and a guide wheel 9 is rotatably provided inside the U-shaped mounting bar 8 , and the guide wheel 9 is slidably matched with the side surface of the second elevator guide rail body 2 .

[0023] By adopting the above technical solution, when the second elevator guide rail body 2 is installed on the top of the first elevator guide rail body 1, the two sides of the second elevator guide rail body 2 are respectively in contact with the two guide wheels 9. At this time, the U-shaped mounting bar 8 and the rotating rod 7 rotate in a small range along the rotation point of the connecting rod 6, and the guide wheel 9 is attached to the second elevator guide rail body 2, which guides the second elevator guide rail body 2 and improves the splicing efficiency of the first elevator guide rail body 1 and the second elevator guide rail body 2.

[0024] Two first mounting blocks 10 and second mounting blocks 11 are fixedly provided at the top and bottom of the connecting rod 6 and the rotating rod 7 respectively; a first rotating seat 12 is fixedly provided on the side of the first mounting block 10 close to the guide wheel 9; a first rotating block 13 is rotatably provided on one end of the first rotating seat 12 close to the guide wheel 9; and an intermediate block 14 is fixedly provided on the side of the first rotating block 13 close to the guide wheel 9.

[0025] By adopting the above technical solution, when the rotating rod 7 rotates, the intermediate block 14 and the first rotating block 13 can be driven to rotate along the axial direction of the first rotating seat 12, so as to achieve the purpose of buffering.

[0026] A buffer damper 15 is fixedly provided on one side of the intermediate block 14 close to the guide wheel 9, a second rotating block 16 is fixedly provided on the output end of the buffer damper 15, a second rotating seat 17 is rotatably provided on one end of the second rotating block 16 close to the guide wheel 9, a side of the second rotating seat 17 close to the guide wheel 9 is fixedly matched with a side of the second mounting block 11 away from the guide wheel 9, a spring 18 is fixedly provided between the first mounting block 10 and the second mounting block 11, and the spring 18 is sleeved on the buffer damper 15.

[0027] By adopting the above technical solution, when the rotating rod 7 rotates along the connection with the connecting rod 6, the buffer damper 15 is driven to rotate along the second rotating seat 17 to extend and retract. At the same time, the spring 18 is lengthened and shortened as the buffer damper 15 is extended and retracted, thereby offsetting the vibration of the connection between the first elevator guide rail body 1 and the second elevator guide rail body 2, thereby protecting the tightness of the connection.

[0028] Reinforcing ribs 19 are fixedly arranged in the first elevator guide rail body 1 and the second elevator guide rail body 2 .

[0029] By adopting the above technical solution, the reinforcing rib 19 has a certain strength, which can further enhance the structural strength of the first elevator guide rail body 1 and the second elevator guide rail body 2, making them less likely to be damaged.

[0030] The guide wheel 9 is made of rubber material.

[0031] By adopting the above technical solution, the surface friction of the rubber is relatively large, so that when the second elevator guide rail body 2 contacts the guide wheel 9, the second elevator guide rail body 2 can slide along the surface of the guide wheel 9 more stably.

[0032] An annular groove 20 is provided at the connection between the guide wheel 9 and the second elevator guide rail body 2 , and the side surface of the second elevator guide rail body 2 is stuck in the annular groove 20 .

[0033] By adopting the above technical solution, the second elevator guide rail body 2 is stuck in the annular groove 20 and slides inside, which can prevent the second elevator guide rail body 2 from being separated from the guide wheel 9, and further improve the guiding effect of the guide wheel 9.

[0034] Working principle: when it is necessary to install the second elevator guide rail body 2 on the top of the first elevator guide rail body 1, move the second elevator guide rail body 2 downward, and the two sides of the second elevator guide rail body 2 are respectively stuck in the annular grooves 20 on the two guide wheels 9, and then move the second elevator guide rail body 2 downward, so that the bottom of the second elevator guide rail body 2 is clamped with the top of the first elevator guide rail body 1. When the elevator is installed on the first elevator guide rail body 1 and the second elevator guide rail body 2 and normally lifted, vibration is generated. At this time, the U-shaped mounting bar 8 and the rotating rod 7 rotate in a small range along the rotation point of the connecting rod 6, driving the middle block 14 and the first rotating block 13 to rotate along the axial direction of the first rotating seat 12, and driving the buffer damper 15 to rotate along the second rotating seat 17 to retract and retract. At the same time, the spring 18 is lengthened and shortened as the buffer damper 15 retracts and retracts, so as to buffer and offset harmful vibrations.

[0035] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
