[0024] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0025] The terms "top surface," "bottom surface," and "underside surface" are used with reference to the normal operating state of the pressure guide plate assembly and are only for the convenience of describing this utility model and simplifying the description. They are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0026] like Figure 1 and 2 As shown, an elevator guide rail pressure plate assembly includes a mounting bracket 2 and a pressure plate 3. The pressure plate 3 fixes the guide rail 1 to the mounting bracket 2. The pressure plate 3 includes a pressing section 31, a side abutment section 32 and an installation section 33 arranged sequentially. The pressing section 31 abuts against the bottom of the guide rail 1, the side abutment section 32 abuts against the side of the guide rail 1, and the installation section 33 is connected to the mounting bracket 2 by a bolt assembly. The installation section 33 is provided with a limit strip 304, and the mounting bracket 2 is provided with a limit groove 202. The limit strip 304 and the limit groove 202 are interlocked.

[0027] The specific installation method of the mounting bracket 2 and the pressure guide plate 3 is as follows: the mounting section 33 has a second mounting hole 302, the mounting bracket 2 has a first mounting hole 201, and the bolt assembly includes a bolt 4 and a nut 5. The bolt 4 passes through the second mounting hole 302 and the first mounting hole 201 in sequence and is then threadedly connected to the nut 5.

[0028] The aforementioned guide plate assembly is suitable for fixing elevator guide rails to improve the firmness and stability of elevator guide rail installation, thereby improving the stability and safety of elevator operation. The mounting bracket 2 is fixed inside the elevator shaft, and two guide plates 3 are installed on the mounting bracket 2 to fix the guide rail 1 from both sides. The pressing section 31, side abutment section 32, and installation section 33 of the guide plate are distributed in a Z-shape. The pressing section 31 tightly abuts against the bottom of the guide rail 1, so that the pressing section 31 and the mounting bracket 2 clamp the bottom of the guide rail 1 from both sides, pressing the guide rail 1 firmly onto the mounting bracket 2. The side abutment section 32 abuts against the side of the bottom of the guide rail 1, limiting the lateral displacement of the guide rail 1. The installation section 33 is fixedly connected to the mounting bracket 2 by bolt assemblies, allowing the guide plate 3 to be installed and removed from the mounting bracket 2 as a whole.

[0029] Compared to the existing method of fixing the guide plate 3 with only a single bolt assembly, this guide plate 3 is also positioned with the mounting bracket 2 by a limiting groove 202 and a limiting strip 304, thereby limiting the displacement of the guide plate 3 under force and reducing the probability of the guide plate 3 shifting, so as to ensure the reliability of the guide plate 3 fixing the guide rail 1, and thus improve the stability and safety of elevator operation; and during the installation of the guide plate 3, the limiting groove 202 and the limiting strip 304 can also improve the convenience of positioning between the guide plate 3 and the mounting bracket 2, thereby improving the convenience of installation and maintenance of the guide plate 3.

[0030] Further improvements include, for example Figure 3-4 As shown, the first direction is the direction of extension along the guide rail 1, the limiting groove 202 extends perpendicular to the first direction, and one of the first mounting hole 201 and the second mounting hole 302 is an oblong hole, which extends perpendicular to the first direction.

[0031] In the aforementioned pressure guide plate assembly, the limiting groove 202 is a through groove. The limiting strips 304 on the two pressure guide plates 3 located on both sides of the guide rail 1 are arranged in the same limiting groove 202. In this way, the limiting groove 202 can limit the installation height of the two pressure guide plates 3 on both sides of the guide rail 1 to be consistent, so that when the side abutment section 32 abuts against the side of the guide rail 3, the force balance of the guide rail 1 in the horizontal direction can be maintained, thereby improving the stability of fixing the guide rail 1. The setting of the waist-shaped hole allows the pressure guide plate 3 to adjust its position along the extension direction of the limiting groove 202, thereby adjusting the distance between the two pressure guide plates 3, so that the pressure guide plate assembly can be used to fix guide rails 1 of different widths. Furthermore, the limiting strips 304 set on the pressure guide plate 3 can also act as reinforcing ribs to strengthen the structural strength of the pressure guide plate 3 and improve the fixing effect of the pressure guide plate 3 on the guide rail 1.

[0032] Further improvements include, for example Figure 4 and 6As shown, the inner bottom wall of the limiting groove 202 has a serrated structure, and the side of the limiting strip 304 facing away from the mounting section 33 also has a serrated structure. When the bolt assembly is tightened, the serrated structures on the limiting groove 202 and the limiting strip 304 can interlock, thereby locking the position of the limiting strip 304 inside the limiting groove 202. At the same time, through the mutual limiting between the limiting strip 304 and the limiting groove 202, the pressure guide plate 3 can resist forces from different directions, further reducing the probability of displacement and loosening of the pressure guide plate 3 and improving the fixing effect of the pressure guide plate 3 on the guide rail 1.

[0033] Further improvements include, for example Figure 5 As shown, a reinforcing rib 301 is provided on the side of the pressure guide plate 3 away from the mounting bracket 2. The reinforcing rib 301 extends along the direction from the pressing section 31 to the mounting section 33. The reinforcing rib 301 can increase the overall structural strength of the pressure guide plate 3 and prevent the pressure guide plate 3 from deforming during use, so as to maintain the fixing effect of the pressure guide plate 3 on the guide rail 1.

[0034] Further improvements include, for example Figure 6 As shown, a chip removal groove 303 is provided on the side of the clamping section 31 that abuts against the guide rail 1; the chip removal groove 303 is a through groove, and the angle between the extension direction of the chip removal groove 303 and the vertical direction is an acute angle. During long-term operation of the elevator, contaminants or impurities generated by friction may accumulate on the contact surface between the pressure guide plate 3 and the guide rail 1. If these contaminants and impurities remain on the contact surface for an extended period, they will exacerbate wear and tear, potentially causing the connection between the pressure guide plate 3 and the guide rail 1 to loosen. The chip removal groove 303 actively removes contaminants and debris from between the pressure guide plate 3 and the guide rail 1, maintaining the cleanliness of the contact surface and reducing wear. The chip removal groove 303 is positioned at an acute angle to the vertical direction, extending at an angle to expand its range and improve chip removal efficiency. Furthermore, contaminants and debris entering the chip removal groove 303 can be facilitated by gravity to be discharged from within the groove, further enhancing its chip removal effect.

[0035] Further improvements include, for example Figure 3 As shown, a protruding strip 203 is provided on the side of the mounting bracket 2 facing away from the pressure guide plate 3, and the protruding strip 203 is set close to the nut 5. The protruding strip 203 can fill the thickness deficiency at the position of the limiting groove 202 of the mounting bracket 2, thereby improving the structural strength of the mounting bracket 2; and the protruding strip 203 set close to the nut 5 can also limit the nut 5, preventing the nut 5 from loosening due to vibration during elevator operation, thereby improving the firmness and stability of the installation between the pressure guide plate 3 and the mounting bracket 2.

[0036] Further improvements include, for example Figure 2As shown, an anti-slip washer 401 is provided between the head of bolt 4 and the mounting section 33. The anti-slip washer 401 is provided with anti-slip texture. The anti-slip washer 401 can increase the friction between bolt 4 and mounting section 33, preventing bolt 4 from loosening due to vibration during elevator operation, thereby further improving the firmness and stability of the installation between pressure guide plate 3 and mounting bracket 2.
