[0023] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0024] Reference Figure 1-5 , an embodiment of the present invention provides a pressure-resistant elevator guide rail, which includes: a T-shaped guide rail 1, and mounting grooves 2 are provided on both sides of the left and right sides of the protrusion of the T-shaped guide rail 1. The front end of the mounting groove 2 passes through the front surface of the T-shaped guide rail 1, and the rear end of the mounting groove 2 does not pass through the rear surface of the T-shaped guide rail 1. The mounting groove 2 is used to provide installation conditions for auxiliary supporting components. A filling block 4 is provided on the inner wall of the mounting groove 2. The rear surface of the filling block 4 is in close contact with the front surface of the vertical plate 10. The filling block 4 is used to close the mounting groove 2 to prevent the vertical plate 10 from falling through the penetration of the T-shaped guide rail 1.

[0025] The inner wall of the mounting groove 2 is provided with a contact piece 3, which is composed of a vertical plate 10 and a contact plate 9. The lower end of the vertical plate 10 is located inside the mounting groove 2, and the contact plate 9 is rotatably connected to the upper surface of the vertical plate 10. The end of the contact plate 9 away from the vertical plate 10 does not contact the protrusion of the T-shaped guide rail 1, and when the guide rail is used, the end of the upper surface of the contact piece 3 close to the protrusion of the T-shaped guide rail 1 is in close contact with the surface of the elevator rail shoe. The contact piece 3 is used to contact the rail shoe of the elevator car, providing basic conditions for adding additional support points to the guide rail. The vertical plate 10 is composed of a long plate and a magnetic limit plate, and the lower end of the flat plate is clamped with the magnetic limit plate. When the elevator guide rail is used, the lower end of the vertical plate 10 and the lower ends of the magnetic limit plate and the long plate are all located inside the mounting groove 2. The vertical plate 10 uses its own magnetic clamping structure to improve the convenience of disassembling and assembling the contact piece 3.

[0026] The surface of the vertical plate 10 is fixedly connected with a bent side panel 7, which is located at the connection between the vertical plate 10 and the contact plate 9, and the end of the bent side panel 7 away from the vertical plate 10 is in close contact with the upper surface of the contact plate 9. The bent side panel 7 is used to limit the upward flipping range of the vertical plate 10. The side of the contact plate 9 close to the protrusion of the T-shaped guide rail 1 is fixedly connected with an arc edge seal 6, which does not contact the protruding part of the T-shaped guide rail 1. The arc edge seal 6 is used to reduce the hidden danger of wear of the T-shaped guide rail 1 during the flipping of the contact plate 9.

[0027] The contact member 3 is fixedly connected to a plurality of load-bearing members 5 on the lower surface of one end of the raised part of the T-shaped guide rail 1. The lower surface of the load-bearing member 5 is in close contact with the surface of the T-shaped guide rail 1. The load-bearing member 5 is composed of two mounting discs 8 and a support spring 11. The two mounting discs 8 are fixedly connected to the upper and lower ends of the support spring 11. The mounting disc 8 at the upper end of the support spring 11 is threadedly connected to the lower surface of the contact plate 9. The mounting disc 8 at the lower end of the support spring 11 is in close contact with the surface of the T-shaped guide rail 1. The diameter of the mounting disc 8 is larger than the diameter of the support spring 11, and the height of the support spring 11 and the two mounting discs 8 added is the same as the height of the lower surface of the contact plate 9. The load-bearing member 5 is used to provide an upward supporting force for the contact member 3, wherein the mounting disc 8 is used to fix the support spring 11 and improve the effect of the support spring 11.

[0028] Working principle: First, push the magnetic limit plate on the lower surface of the vertical plate 10 in the contact piece 3 into the interior of the installation groove 2, and use the filling block 4 to close the installation groove 2 to prevent the vertical plate 10 from detaching from the T-shaped guide rail 1, and then press the long plate into the installation groove 2 from top to bottom so that the long plate is engaged with the magnetic limit plate to complete the installation of the vertical plate 10, and then the guide rail can be installed to the specified position. After the guide rail is installed, the contact plate 9 directly contacts the rail shoe of the car. At this time, the support spring 11 contracts under pressure, and the connection method between the contact plate 9 and the vertical plate 10 provides compression space for the support spring 11. When the guide rail is subjected to vibration, the contact plate 9 and the support spring 11 can alleviate the negative impact of the vibration. When the guide rail needs to be maintained, directly pull the vertical plate 10 to separate the vertical plate 10 from the limit plate to remove the contact piece 3 and the load-bearing member 5.

[0029] During the use of this guide rail, the support spring 11 remains in a stable state due to the pressure, wherein the mounting disc 8 at the bottom of the support spring 11 improves the balancing force of the support spring 11, and the bent side panel 7 is a prefabricated part. During specific use, the bending angle of the bent portion of the side panel can be changed to change the downward flipping angle of the contact plate 9, thereby further limiting the range of the contact plate 9 flipping upward under the influence of the support spring 11, thereby reducing the negative impact of the stress of the support spring 11 on the car rail shoe.

[0030] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
