[0030] It should also be noted that the directional terms mentioned in the embodiments, such as "up," "down," "front," "back," "left," and "right," are only for reference in the accompanying drawings and are not intended to limit the scope of protection of this utility model. Throughout the drawings, the same elements are represented by the same or similar reference numerals. Conventional structures or constructions will be omitted where they may cause confusion in understanding this utility model.

[0031] During elevator operation, the elevator car's guide shoes slide along the guide rail assembly. The guide rail assembly consists of multiple guide rails connected end-to-end, extending in a generally vertical direction to guide the elevator car. Gaps occur at the connection points of adjacent guide rails, and the stiffness of these connections decreases. As the guide shoes slide along the guide rail assembly to the connection points of adjacent guide rails, noise is generated due to the gaps and changes in the stiffness of the guide rail assembly, resulting in a poor elevator riding experience for passengers.

[0032] Figure 1 A perspective view of a guide rail assembly according to an embodiment of the present invention is shown schematically. Figure 2 A perspective view of a guide rail assembly according to another embodiment of the present invention is shown schematically.

[0033] The first aspect of this utility model provides a connection mechanism suitable for elevator guide rail assemblies, such as... Figure 1 and Figure 2 As shown, the guide rail assembly 1 is formed by multiple guide rails 11 connected end to end. Each guide rail 11 includes a base 12 and a protrusion 13 that slides with the elevator.

[0034] The connecting mechanism includes a connecting component 2 and multiple pressing components 3. The connecting component 2 is disposed at the connection position of the adjacent guide rail 11 and is located on the side of the base 12 opposite to the protrusion 13. The multiple pressing components 3 are disposed on both sides of the base 12 located on the protrusion 13, and the pressing components 3 are wrapped around and fastened to the outside of the base 12 and are detachably connected to the connecting component 2.

[0035] In detail, such as Figure 1 and Figure 2 As shown, multiple guide rails 11 are connected end-to-end in the vertical direction to form a guide rail assembly 1. The guide rail assembly 1 is generally installed on the side wall of the elevator shaft via guide rail 11 brackets. Adjacent guide rails 11 include a first guide rail 111 located at the top and a second guide rail 112 located at the bottom. The base 12 of the guide rail 11 faces the side wall of the shaft. The middle part of the base 12 facing away from the side wall of the shaft protrudes outward to form a protrusion 13, that is, the protrusion 13 is located on the side facing the elevator car. The protrusion 13 and the base 12 are connected to each other to form an integral structure.

[0036] It should be noted that the cross-section of the end of the protrusion 13 furthest from the base 12 is approximately C-shaped. The elevator car is equipped with a guide shoe (not shown in the figure) that mates with the protrusion 13. Specifically, the guide shoe has a groove that mates with the protrusion 13, and the groove is approximately C-shaped. During the elevator car's vertical movement, the guide shoe moves with the car and slides vertically along the protrusion 13 of the guide rail 11.

[0037] Furthermore, such as Figure 1 and Figure 2 As shown, the connecting component 2 is located on the side of the base 12 opposite to the protrusion 13, and spans the connection position of the first guide rail 111 and the second guide rail 112. Multiple pressing components 3 are located on both sides of the base 12 opposite to the protrusion 13. Figure 1 The pressing component 3 surrounds the base 12 on both sides of the protrusion 13, and is fastened around the base 12 to create a circumferential fastening effect. The circumferential fastening refers to the pressing component 3 surrounding the base 12 on both sides of the protrusion 13, contacting the outer surface of the base 12, and pressing the base 12 towards the connecting component 2. This makes the area of ​​the base 12 on both sides of the protrusion 13 fastened between the pressing component 3 and the connecting component 2, creating a circumferential fastening effect, thereby strengthening the fastening of the connection between the first guide rail 111 and the second guide rail 112.

[0038] Specifically, such as Figure 1 and Figure 2 As shown, four pressing components 3 are provided, two of which are located on the base 12 of the first guide rail 111 on both sides of the protrusion 13, and the other two pressing components 3 are located on the base 12 of the second guide rail 112 on both sides of the protrusion 13.

[0039] It is understandable that there can be two pressing components 3, with the two pressing components 3 located on both sides of the base 12 and the protrusion 13 respectively. The two pressing components 3 span the connection between the first guide rail 111 and the second guide rail 112, so that the ends of the first guide rail 111 and the second guide rail 112 connected to each other can be fastened together, producing a circumferential fastening effect and strengthening the fastening of the connection between the first guide rail 111 and the second guide rail 112.

[0040] It should be noted that the pressing component 3 is located on the base 12 of the guide rail 11, which is located on both sides of the protrusion 13. That is, the pressing component 3 and the protrusion 13 do not interfere with each other. The pressing component 3 and the guide shoe of the car are spaced apart to ensure that the guide shoe of the elevator car slides normally along the protrusion 13 of the guide rail 11.

[0041] The pressing component 3 includes, but is not limited to, being detachably connected to the connecting component 2 by means of bolts, snap-fit ​​components, clamp components or any other connection method, so as to facilitate disassembly and replacement and improve the convenience of disassembly and maintenance.

[0042] According to an embodiment of this utility model, when installing the first guide rail 111 and the second guide rail 112, firstly, the connecting component 2 is installed on the side of the base 12 of the second guide rail 112 away from the protrusion 13. Then, the bottom end of the first guide rail 111 is aligned with the top end of the second guide rail 112. Next, the first guide rail 111 is connected to the connecting component 2. Finally, the pressing component 3 is wrapped around and fastened to the outside of the base 12, and detachably connected to the connecting component 2, completing the installation.

[0043] In this embodiment, by setting a connecting component 2 and a pressing component 3 at the connection position of adjacent guide rails 11, the connecting component 2 is set on the side of the base 12 away from the protrusion 13, and the pressing component 3 is set on both sides of the base 12 located on the protrusion 13 and is wrapped around and fastened to the outside of the base 12, a circumferential fastening effect is generated, thereby strengthening the fastness of the connection position of the guide rails 11, strengthening the rigidity of the connection area of ​​the guide rails 11, reducing the deformation and displacement of the connection area of ​​adjacent guide rails 11, reducing elevator operating noise, and improving the passenger's elevator riding experience.

[0044] Figure 3 The schematic diagram illustrates a partial view of a guide rail assembly according to an embodiment of the present invention.

[0045] In one exemplary embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the connecting assembly 2 includes a connecting portion 21 and two sets of extension portions 22. The connecting portion 21 is connected to the side of the base 12 opposite to the protrusion 13. The two sets of extension portions 22 are respectively connected to both ends of the connecting portion 21 in the height direction of the guide rail 11. Figure 1 The top and bottom ends of the connecting part 21), each set of extensions 22 in the width direction of the guide rail 11 ( Figure 1 The base 12 extends integrally from both sides of the connecting part 21 in a transverse direction parallel to the connecting part 21 and is connected to the pressing assembly 3.

[0046] In detail, the connecting part 21 is a plate-shaped structure that spans the first guide rail 111 and the second guide rail 112. The connecting part 21 is generally installed on the side of the base 12 away from the protrusion 13 by bolts. In this way, the first guide rail 111 and the second guide rail 112 are connected to each other through the connecting part 21.

[0047] Each set of extensions 22 extends integrally from the connecting portion 21 to both sides of the base 12 in the width direction of the guide rail 11. That is, in the width direction of the guide rail 11, the width of the extension 22 is greater than the width of the base 12. The extension 22 extends to the left and right sides of the base 12 to connect with the pressing assembly 3.

[0048] Figure 4A perspective view of a guide rail assembly according to another embodiment of the present invention is shown schematically.

[0049] In an alternative exemplary embodiment, such as Figure 4 As shown, the connecting component 2 includes a connecting portion 21 and an annular portion 23. The connecting portion 21 is connected to the side of the base 12 opposite to the protrusion 13. The annular portion 23 is disposed on the side of the base 12 opposite to the protrusion 13 and surrounds the connecting portion 21. The annular portion 23 extends outward from both sides of the base 12 in the width direction of the guide rail 11 and is connected to the pressing component 3.

[0050] In detail, the connecting part 21 is a plate-shaped structure that spans the first guide rail 111 and the second guide rail 112. The connecting part 21 is generally installed on the side of the base 12 away from the protrusion 13 by bolts. In this way, the first guide rail 111 and the second guide rail 112 are connected to each other through the connecting part 21.

[0051] The annular portion 23 has a rectangular ring structure, meaning that the center of the annular portion 23 has a hollow structure forming a through hole. The through hole is used to accommodate the connecting portion 21, meaning that the annular portion 23 surrounds the connecting portion 21. In the width direction of the guide rail 11, the width of the annular portion 23 is greater than the width of the base 12, and the annular portion 23 extends beyond the left and right sides of the base 12 to connect with the pressing assembly 3.

[0052] In one exemplary embodiment, such as Figure 1 and Figure 2 As shown, the connecting portion 21 bends towards the base 12 on both sides parallel to the height direction of the guide rail 11 to form limiting portions 211. The two limiting portions 211 contact the base 12 to prevent the connecting portion 21 from moving relative to the base 12 in the width direction.

[0053] In detail, the left and right sides of the connecting portion 21 bend towards the base 12 and contact the base 12 to form limiting portions 211, that is, the two limiting portions 211 respectively abut against the side walls of the base 12 on both sides of the protrusion 13. At the same time, the limiting portions 211 span the connection position of the first guide rail 111 and the second guide rail 112.

[0054] In this embodiment, the two limiting portions 211 prevent the connecting portion 21 from moving relative to the base 12 in the width direction, thereby improving the stability of the connecting portion 21 mounted on the guide rail 11. The limiting portions 211 span the connection position of the first guide rail 111 and the second guide rail 112, aligning the first guide rail 111 and the second guide rail 112 and reducing the degree of misalignment between the first guide rail 111 and the second guide rail 112.

[0055] In one exemplary embodiment, such as Figure 2As shown, the base 12 includes a first part 121 and a second part 122. The first part 121 is opposite to the connecting component 2, and the second part 122 has an L-shaped cross section and is connected between the first part 121 and the protrusion 13.

[0056] Specifically, such as Figure 2 As shown, the first part 121 is a plate-like structure and abuts against the connecting part 21. Two second parts 122 are provided, each integrally connected to one of the two sides of the first part 121 in the vertical direction. Figure 2 (The left and right sides of the connecting part 21). The cross-section of the second part 122 is L-shaped. The ends of the two second parts 122 away from the first part 121 are integrally connected with the protrusion 13 to form a hollow structure, which is T-shaped.

[0057] In one exemplary embodiment, such as Figure 1 and Figure 2 As shown, each pressing component 3 includes a pressing part 31 and a mounting part 32. The pressing part 31 has an L-shaped cross-section and is wrapped around the second part 122, so that the base 12 is pressed between the connecting component 2 and the pressing part 31. The mounting part 32 is connected to the end of the pressing part 31 near the connecting component 2 for detachable connection with the connecting component 2.

[0058] In detail, the pressing part 31 is defined based on the shape of the second part 122, that is, the cross-section of the pressing part 31 is L-shaped. The pressing part 31 is snapped around the second part 122, so that the base 12 is pressed between the connecting component 2 and the pressing part 31.

[0059] The mounting part 32 is connected to the end of the pressing part 31 near the connecting assembly 2. The mounting part 32 is parallel to and in contact with the extension 22 or the annular part 23 of the connecting assembly 2. The mounting part 32 is detachably connected to the connecting assembly 2 by means of bolts, snap-fit ​​components, clamp components or any other mounting method.

[0060] According to an embodiment of the present invention, the pressing part 31 is wrapped around and fastened to the outside of the second part 122, so that the base 12 is pressed between the connecting component 2 and the pressing part 31, producing a circumferential and tight-fitting effect, thereby strengthening the tightness of the connection position of the first guide rail 111 and the second guide rail 112, strengthening the rigidity of the connection area of ​​the guide rail 11, reducing the deformation and displacement of the connection area of ​​adjacent guide rails 11, reducing elevator operating noise, and improving the passenger's elevator riding experience.

[0061] In one exemplary embodiment, such as Figure 3 As shown, reinforcing ribs are provided on the pressing part 31 and the mounting part 32 to improve the rigidity of the pressing assembly 3.

[0062] In one exemplary embodiment, such as Figure 1 and Figure 2As shown, the connecting mechanism also includes multiple mounting components 4, which are configured to connect the mounting part 32 and the connecting component 2.

[0063] Specifically, the number of mounting components 4 is the same as the number of pressing components 3. Mounting components 4 can be bolts, snap-fit ​​components, clamping components, etc., depending on actual needs. Mounting components 4 mount the mounting part 32 to the extension 22 or the annular part 23 of the connecting component 2. Mounting components 4 are easy to assemble and disassemble, facilitating the replacement of the connecting mechanism and the guide rail 11.

[0064] In one exemplary embodiment, such as Figure 1 and Figure 2 As shown, the mounting assembly 4 includes a first locking part 41 and a second locking part 42. The first locking part 41 passes through the mounting part 32 and connects to the connecting assembly 2.

The pressing part 31 of the mounting assembly 4 is wrapped around and fastened to the outside of the second part 122. The mounting part 32 of the mounting assembly 4 contacts the connecting assembly 2. The first locking part 41 passes through the mounting part 32 and the connecting assembly 2. Then, the second locking part 42 engages with the first locking part 41 by thread, thereby fastening and locking the mounting part 32 and the connecting assembly 2, so that the base 12 is pressed between the connecting assembly 2 and the pressing part 31. The connecting mechanism is easy to assemble and disassemble, and convenient for replacement and maintenance.

The second adapter mechanism 6 is disposed on the inner wall of the hollow structure of the second guide rail 112 opposite to the connecting component 2 of the connecting mechanism, so as to be detachably connected to the connecting component 2, and to be inserted into the first adapter mechanism 5.

[0069] In detail, the first adapter mechanism 5 and the second adapter mechanism 6 can be plate-like structures, block-like structures, etc., specifically limited according to actual needs. The first adapter mechanism 5 and the second adapter mechanism 6 are inserted and fitted together to guide the first guide rail 111 to move downward and mate with the second guide rail 112, and in the width direction of the guide rail 11 ( Figure 2 In the transverse direction parallel to the connecting part 21, the first adapter mechanism 5 and the second adapter mechanism 6 are prevented from moving relative to each other and becoming misaligned.

[0070] According to an embodiment of this utility model, when the first guide rail 111 and the second guide rail 112 are connected and installed, the second adapter mechanism 6 is pre-installed in the hollow structure of the second guide rail 112 by bolts, and is located on the inner wall of the first part 121 of the base 12 of the second guide rail 112. The connecting component 2 is placed on the side of the base 12 opposite to the protrusion 13, and bolts pass through the connecting component 2, the base 12 and the second adapter mechanism 6 to install the connecting component 2 onto the second guide rail 112. The first adapter mechanism 5 is pre-installed in the hollow structure at the bottom of the first guide rail 111 by bolts, and is located on the inner wall of the first part 121 of the base 12 of the first guide rail 111. Then, the bottom of the first guide rail 111 is connected to the top of the second guide rail 112, and the locking installation is completed by bolts passing through the connecting component 2, the base 12 and the first adapter mechanism 5. Finally, the multiple pressing components 3 of the connecting mechanism are wrapped around and fastened to both sides of the base 12 located on the protrusion 13, and detachably connected to the connecting component 2 to complete the installation.

The first connecting plate 51 is disposed on the inner wall of the hollow structure of the first guide rail 111 opposite to the connecting component 2. A slot 52 for insertion and cooperation with the second adapter mechanism 6 is provided on the side of the first connecting plate 51 adjacent to the second guide rail 112.

[0073] In detail, the first connecting plate 51 is mounted to the inner wall of the hollow structure of the first guide rail 111, opposite to the connecting assembly 2, via a mounting component. The mounting component can be a bolt, screw, rivet, etc., and is not limited here. It is understood that the first connecting plate 51 can also be mounted to the first guide rail 111 by welding. The bottom end of the first connecting plate 51 is provided with a slot 52 for insertion and engagement with the second adapter mechanism 6.

[0074] In one exemplary embodiment, such as Figure 1 and Figure 2 As shown, a through hole is provided at the position of the connecting portion 21 of the connecting assembly 2 opposite to the mounting member. The through hole extends in the height direction of the guide rail 11 to allow the mounting member protruding from the first guide rail 111 to be placed in the through hole, so that the outer wall of the first guide rail 111 abuts against the connecting portion 21 of the connecting assembly 2. The through hole extends in the height direction of the guide rail 11 so that when the mounting member moves downward with the first guide rail 111 and mates with the second guide rail 112, it can slide in the through hole to complete the mating of the first guide rail 111 and the second guide rail 112.

[0075] In one exemplary embodiment, such as Figure 1 and Figure 2 As shown, the second adapter mechanism 6 includes a second connecting plate 61 and a reinforcing part 62. The second connecting plate 61 is disposed on the inner wall of the hollow structure of the second guide rail 112 opposite to the connecting assembly 2. The reinforcing part 62 is connected to the second connecting plate 61 and inserted into the slot 52 to guide the first guide rail 111 and the second guide rail 112 to align when the first guide rail 111 is lowered to mate with the second guide rail 112.

[0076] In detail, the second connecting plate 61 is located on the inner wall of the hollow structure of the second guide rail 112, opposite to the connecting assembly 2. The reinforcing part 62 is connected to the top of the second connecting plate 61 by welding or other means, and is inserted into the slot 52 of the first connecting plate 51.

[0077] It should be noted that the top of the reinforcing post is higher than the top of the second guide rail 112, extending beyond the top of the second guide rail 112. When the bottom end of the first guide rail 111 mates downward with the second guide rail 112, the reinforcing post slides into the slot 52 to guide the installation of the first guide rail 111, aligning the first guide rail 111 and the second guide rail 112, thus improving the ease of installation.

[0078] In one exemplary embodiment, such as Figure 2As shown, the reinforcing part 62 extends into the protrusion 13 and abuts against the inner wall of the protrusion 13. In this way, the reinforcing part 62 is located inside the hollow structure of the protrusion 13 and generates a supporting force on the protrusion 13, thereby increasing the rigidity of the protrusion 13 and the rigidity of the connection area between the first guide rail 111 and the second guide rail 112, reducing the deformation and displacement of the connection area of ​​adjacent guide rails 11, and reducing elevator operating noise.

[0079] In one exemplary embodiment, such as Figure 1 and Figure 3 As shown, the second connecting plate 61 is provided with a guide 9 extending outward from the base 12. The lower part of the connecting assembly 2 is provided with a guide groove 7 extending in the height direction and opening downward. The guide groove 7 is configured to guide the connecting assembly 2 to slide and prevent the connecting assembly 2 from moving further relative to the second guide rail 112 when the guide 9 contacts the top of the guide groove 7.

[0080] In detail, the guide 9 may be a bolt that passes through the base 12 and the second connecting plate 61 to mount the second connecting plate 61 to the base 12 of the second guide rail 112.

[0081] In this embodiment, after the second connecting plate 61 is mounted on the second guide rail 112 via the guide member 9, during the installation of the connecting assembly 2, the guide groove 7 of the connecting assembly 2 is aligned with the guide member 9, and then the connecting assembly 2 is moved downward relative to the second guide rail 112. At this time, the guide member 9 and the guide groove 7 guide the connecting assembly 2 to slide, and when the guide member 9 contacts the top of the guide groove 7, it prevents the connecting assembly 2 from moving further relative to the second guide rail 112, thereby defining the position of the connecting assembly 2 relative to the first guide rail 111 and the second guide rail 112.

[0082] In one exemplary embodiment, such as Figure 2 As shown, a reinforcing plate 8 is detachably connected to the side of the connecting component 2 away from the base 12. The reinforcing plate 8 spans the guide groove 7 to enhance the rigidity of the area of ​​the connecting component 2 adjacent to the guide groove 7.

[0083] A second aspect of this invention provides an elevator, comprising the connecting mechanism described above or the guide rail assembly 1 described above, and a car. The guide rail 11 of the guide rail assembly 1 guides the car to move up and down.

[0084] According to the connecting mechanism, guide rail assembly, and elevator provided in this embodiment, multiple guide rails 11 connected end to end form a guide rail assembly 1. Therefore, gaps will occur at the connection points of adjacent guide rails 11, causing noise during the elevator's sliding motion along the protrusion 13. By providing a connecting component 2 and a pressing component 3 at the connection points of adjacent guide rails 11, the connecting component 2 is located on the side of the base 12 away from the protrusion 13, and the pressing component 3 is located on both sides of the base 12 and surrounds and fastens to the outside of the base 12, creating a circumferential tightening effect. This strengthens the tightness of the connection points of the guide rails 11, enhances the rigidity of the connection area of ​​the guide rails 11, reduces the deformation and displacement of the connection area of ​​adjacent guide rails 11, reduces elevator operating noise, and improves the passenger experience when riding the elevator.
