Technical Field

[0001] This utility model belongs to the technical field of guide rail connectors, and in particular relates to a high-strength hollow elevator guide rail connector. Background Technology

[0002] Hollow elevator guide rails, as an important component of elevator systems, offer advantages such as lightweight design, cost-effectiveness, and ease of installation. In terms of cross-sectional shape, guide rails can be categorized into three types: T-shaped, L-shaped, and hollow. Among these, T-shaped guide rails are the most commonly used type in elevators due to their high rigidity, reliability, safety, and affordability.

[0003] Because a single hollow guide rail is relatively long and has a small cross-sectional area, it is difficult to ensure the connection accuracy at the ends when connecting two guide rails. This makes it difficult for the straightness of the rail to meet the standard, increases the construction difficulty, and affects the stability and comfort of elevator operation.

[0004] Therefore, it is necessary to improve the existing hollow guide rail connectors for elevators. Utility Model Content

[0005] The purpose of this invention is to overcome the defects in the existing technology and provide a high-strength hollow elevator guide rail connector, which improves the accuracy of guide rail docking and enhances the smoothness and comfort of elevator operation.

[0027] 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.

[0028] The terms "top surface," "bottom surface," and "underside surface" refer to the normal operating state of the hollow elevator guide rail connector. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] like Figure 1-7 As shown, a high-strength hollow elevator guide rail connector includes a main body 3, which is fixedly connected to the guide rail 1 by a bolt assembly 2. The main body 3 includes a U-shaped inner support part 31 and a fixing part 32 fixed on both sides of the groove opening; a width adjusting part 4, which is disposed inside the inner support part 31 and is used to adjust the width of the inner support part 31; and a leveling part 5, which is disposed inside the inner support part 31 and has a telescopic part that penetrates the side wall of the inner support part 31 and is used to adjust the width of the guide rail 1.

[0030] The above-mentioned connectors are used for, for example Figure 1The elevator hollow guide rail 1 shown is connected at its ends. The guide rail 1 includes a U-shaped groove track portion 101 and mounting portions 102 fixed on both sides of the groove. Both the fixing portion 32 and the mounting portion 102 have bolt holes 321 for mounting bolt assemblies 2. When the connector is in use, the bolt holes 321 of the mounting portions 102 at the ends of the two guide rails 1 are aligned with the bolt holes 321 on the fixing portion 32. Then, the bolt assembly 2 is installed inside the bolt holes 321. The bolt assembly 2 is used to achieve a fixed connection between the mounting portion 102 and the fixing portion 32, thereby achieving the connection of the ends of the two guide rails 1. The inner support portion 31 extends into the interior of the track portion 101 and supports the track portion 101 from the inside, thereby achieving the positioning of the ends of the two guide rails 1. Multiple width adjustment pieces 4 are provided on the inner side of the inner support portion 31 and are distributed at intervals along the extension direction of the track 1. The width adjustment pieces 4 can be used to adjust the distance between the two side walls of the inner support portion, thereby... The width of the inner support part 31 is adjusted so that it can adapt to the inner width of the track part 101, making the outer wall of the inner support part 31 fit tightly against the inner wall of the track part 101. This improves the support effect of the inner support part 31 on the track 1, thereby improving the positioning effect of the inner support part 31 on the track 1 and increasing the accuracy of the docking of the two tracks 1. Two leveling parts 5 are provided on the inner side of the inner support part 31. The two leveling parts 5 are located at positions corresponding to the ends of the two tracks 1, so that the telescopic part of the leveling part 5 can abut against the inner side wall of the end of the track part 101 after passing through the side wall of the inner support part 31. When the leveling part 5 is working, the telescopic part extends and retracts, thereby adjusting the distance between the two side walls of the track part 101, making the width of the docking ends of the two tracks 1 consistent, thus making the transition between the two tracks 1 smooth, thereby reducing the vibration of the elevator when running on the track 1 and improving the comfort and stability of the elevator.

[0031] Further improvements include, for example Figure 4 and 6As shown, the width adjustment component 4 includes a first rotating head 401 and two first studs 402 with opposite thread distribution directions. The two first studs 402 are coaxially arranged and fixed on both sides of the first rotating head 401 respectively. Both first studs 402 are threadedly connected to threaded sleeves 314 that are fixedly connected to the inner sidewall of the inner support part 31. The first rotating head 401 has a regular hexagonal prism structure, allowing it to be matched with a wrench. The first rotating head 401 and the first stud 402 are coaxially arranged. During adjustment, the first rotating head 401 is turned by the wrench, causing the two first studs 402 to rotate. The first studs 402 control the two threaded sleeves 314 to move closer or further apart. During the movement of the threaded sleeves 314, they push the two side walls of the inner support part 31 to move, thereby adjusting the distance between the two side walls of the inner support part 31. Ultimately, this adjusts the width of the inner support part 31, allowing it to better fit the gap between the two inner walls of the track part 101, ensuring a tight fit between the inner support part 31 and the track part 101, and improving the support and positioning effect of the inner support part 31 on the track 1.

[0032] Further improvements include, for example Figure 5 and 7 As shown, the leveling component 5 includes a second rotating head 501 and two second studs 504 respectively disposed on its two sides. The second studs 504 slide in cooperation with the second rotating head 501 along their own axial direction. Threaded through holes 313 are provided on both side walls of the inner support part 31, and the second studs 504 are threaded in cooperation with the threaded through holes 313. A prism-shaped plug 503 is provided at the end of the second stud 504, and a plug hole 502 is provided on the second rotating head 501. The plug 503 slides in cooperation with the plug hole 502. The second rotating head 510 has a regular hexagonal prism structure, making it compatible with a wrench. During adjustment, the second rotating head 510 is rotated by the wrench, causing the second rotating head 501 to drive the second stud 504 to rotate, thus moving the second stud 504 inside the threaded through hole 313. The threads of the two second studs 504 match the threads of the threaded through hole 313, allowing the two second studs 504 to move away from or towards each other. After passing through the threaded through hole 313, the second studs 504 abut against the inner walls on both sides of the end of the track section 101, allowing the second studs 504 to push the side walls of the track section 101 for fine adjustment, so that the width of the joint ends of the two tracks 1 are consistent, thereby achieving a smooth transition between the two tracks 1, and thus improving the stability and comfort of elevator operation.

[0033] Further improvements include, for example Figure 3As shown, both inner walls of the inner support portion 31 are provided with protruding ribs; the protruding ribs include a first protruding rib 311 distributed laterally and a second protruding rib 312 distributed longitudinally. The first protruding rib 311 and the second protruding rib 312 are arranged intersectingly. The connection points of the width adjusting member 4 and the leveling member 5 with the inner support portion 31 are located at the intersection of the first protruding rib 311 and the second protruding rib 312. The protruding ribs can strengthen the side walls of the inner support portion 31 and improve the strength of the inner support portion 31. The protruding ribs, divided into the first protruding rib 311 and the second protruding rib 312, can strengthen the side walls of the inner support portion 31 from different directions, further improving the strength of the inner support portion 31.

[0034] Further improvements include, for example Figure 2 As shown, the bolt hole 321 on the fixing part 32 is an oblong hole. The oblong hole allows the fixing part 32 to be displaced accordingly when the width adjustment part 4 adjusts the width of the inner support part 31, thereby reducing the resistance to the adjustment part 4 during adjustment.
