Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of elevator guide rail docking auxiliary devices, specifically relating to an elevator guide rail docking device. Background Technology
[0002] Elevator guide rails are elevator components made of steel rails and connecting plates, mainly including car guide rails and counterweight guide rails. The commonly used guide rail type is the "T"-shaped guide rail, which has good rigidity and high operational reliability.
[0003] During elevator guide rail installation, multiple sections of guide rail typically need to be joined together. The traditional method involves roughly assembling the guide rails, initially semi-tightening them with bolts, and then, after the entire guide rail section is in place, measuring the flatness and alignment of the joints with a ruler, fine-tuning with a hammer, and finally tightening the bolts. This method is cumbersome, inefficient, requires a high level of experience from the installers, and is prone to errors in guide rail joining.
[0004] To address the aforementioned issues, existing technologies, such as the utility model with publication number CN220283230U, propose a magnetic elevator guide rail connector. This connector, through the cooperation of a bracket, a limiting bracket, and a handle screw, can auxiliaryly fix two T-shaped guide rails that need to be joined. This allows for a one-time clamping of the guide rail interface to a standard position, and the bolts on the guide rails can be tightened in one go without secondary adjustments. Furthermore, once the guide rails are joined, the handle screw can quickly clamp and fix the two T-shaped guide rails, freeing up the workers' hands. One worker can easily complete the task, making it convenient to operate and improving work efficiency.
[0005] However, the aforementioned magnetic connector still has some shortcomings in practical use. For example, if care is not taken during the loosening process, the handle screw may slip off or fall off, posing a safety hazard of falling into the elevator shaft. Furthermore, the connector has a relatively complex structure, involves many processing steps, and has a relatively high manufacturing cost, leaving room for further optimization.
[0006] Therefore, we propose an elevator guide rail connector to solve the above-mentioned technical problems. Utility Model Content
[0007] In order to solve the technical problems existing in the prior art, this utility model proposes an elevator guide rail connector.
[0008] The technical solution adopted in this utility model is as follows:
[0009] An elevator guide rail connector includes a bracket. Multiple screw holes are spaced apart along the length of one side of the bracket. A clamping bolt is threaded into each screw hole. A back screw is threaded to the screw end of each clamping bolt. The outer diameter of the nut end of the back screw is larger than the diameter of the screw hole. An internal hexagonal groove is formed on the top surface of the nut end of the back screw. Multiple adjustment holes are formed on the other side of the bracket, with the positions of the adjustment holes corresponding one-to-one with the internal hexagonal grooves.
[0010] In a further technical solution, a handle is fixedly installed on the outer surface of the bracket.
[0011] In a further technical solution, an observation hole is provided on the bracket.
[0012] In a further technical solution, the inner wall of the bracket is provided with multiple mounting slots spaced apart along the length direction, and a strong magnet is fixedly installed in each mounting slot.
[0013] In a further technical solution, the top surface of the undercut screw is provided with a soft rubber pad.
[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0015] 1. The inverted screw of this utility model has a limiting function, which can prevent the clamping bolt from coming out of the bracket during the loosening or disassembly process, and avoid it from accidentally slipping into the elevator shaft, thereby improving the safety of use.
[0016] 2. This utility model has a simple structure. The main components are a bracket, a clamping bolt, and a back screw. The clamping bolt can be modified from an ordinary bolt and used with a simple-processed back screw. It is not only easy to process, but also has a low manufacturing cost, which facilitates mass production and promotion and has good market application prospects.
[0017] 3. The observation hole provided in this utility model serves for observation and adjustment. It allows observation of the alignment of the two guide rails inside the bracket, and allows adjustment tools to be inserted into the bracket to tap and adjust the two guide rails, further ensuring the parallelism and alignment of the guide rails. This effectively improves the alignment accuracy and quality of the guide rails, reduces installation errors, increases construction efficiency and reliability, and enhances the ease of installation.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0025] See Figures 1-4 This utility model provides an elevator guide rail connector, including a bracket 1. A plurality of screw holes 2 are spaced apart along the length of one side of the bracket 1. Each screw hole 2 is threaded with a clamping bolt 3. The screw end of the clamping bolt 3 is threaded with a back screw 4. The outer diameter of the nut end of the back screw 4 is larger than the diameter of the screw hole 2. The top surface of the nut end of the back screw 4 is provided with an internal hexagonal groove 5. A plurality of adjustment holes 6 are provided on the other side of the bracket 1. The positions of the adjustment holes 6 correspond one-to-one with the internal hexagonal grooves 5.
[0026] The working principle of this elevator guide rail connector is as follows:
[0027] The bracket 1, as the main structure of the device, has multiple screw holes 2 spaced along its length on one side, preferably four, arranged symmetrically, for installing the clamping bolts 3. This facilitates even force distribution and provides stable and reliable clamping support. Before use, the construction personnel need to use an Allen wrench to insert it into the adjustment hole 6 on the other side of the bracket 1, and operate it in conjunction with the hexagonal groove 5 of the undercut screw 4 to thread the undercut screw 4 onto the screw end of the clamping bolt 3. Only after assembly can it be used for construction. In actual guide rail docking construction, the construction personnel install this elevator guide rail connector between the two guide rails to be spliced. By tightening the clamping bolts 3, the undercut screw 4 at the front end of the clamping bolt 3 presses against the guide rail, thereby achieving rapid alignment and clamping of the two guide rails. After clamping, the construction personnel's hands are freed, supporting independent operation by one person, simplifying the installation process, improving installation efficiency, and effectively reducing the construction burden. Furthermore, since the outer diameter of the nut end of the undercut screw 4 is larger than the diameter of the screw hole 2, it has a limiting function. During loosening or disassembly, the undercut screw 4 can prevent the clamping bolt 3 from coming out of the bracket 1, avoiding its accidental slippage into the elevator shaft, thereby improving safety. Compared with existing connectors, this elevator guide rail connector has a simple structure. The main components are the bracket 1, the clamping bolt 3, and the undercut screw 4. The clamping bolt 3 can be modified from an ordinary bolt and used with the simply machined undercut screw 4. It is not only easy to process but also has a low manufacturing cost, making it easy to mass-produce and promote, and has good market application prospects.
[0028] In one specific implementation, see Figure 1 and Figure 2 A handle 7 is fixedly installed on the outer surface of the bracket 1.
[0029] The handle 7, located on the outer surface of the bracket 1, allows construction workers to easily grip the elevator guide rail connector during handling, installation, or disassembly, thus improving the user experience.
[0030] In one specific implementation, see Figure 1 and Figure 2 The bracket 1 is provided with an observation hole 8.
[0031] An observation hole 8 is provided on the bracket 1 to facilitate the observation of the alignment of the two guide rails inside the bracket 1 during use. This helps determine the engagement status of the guide rails, facilitating subsequent fine-tuning operations, thereby effectively improving the alignment accuracy and quality of the guide rails, reducing installation errors, and increasing construction efficiency and reliability. It is worth mentioning that the size of the observation hole 8 can be reasonably enlarged to allow adjustment tools to be inserted into the bracket 1 for tapping adjustments of the two guide rails, further ensuring the parallelism and alignment of the guide rails and enhancing the ease of installation. To avoid the handle 7 interfering with the view and adjustment operations of the observation hole 8, the handle 7 is preferably designed with an eccentricity, ensuring that the observation and adjustment functions of the observation hole 8 are not affected.
[0032] In one specific implementation, see Figure 3 The inner wall of the bracket 1 is provided with a plurality of mounting grooves 9 spaced apart along the length direction, and a strong magnet 10 is fixedly installed in each mounting groove 9.
[0033] By setting an installation groove 9 on the inner wall of the bracket 1 and installing a strong magnet 10, a magnetic attraction force can be provided when the elevator guide rail connector is close to the guide rail, so that the bracket 1 can be quickly attached to the surface of the guide rail, realizing the temporary fixation of the elevator guide rail connector, effectively improving the convenience of installation and operation efficiency, reducing the need for manual support of the bracket 1, and further reducing the labor intensity of construction personnel.
[0034] In one specific implementation, see Figure 4 The top surface of the undercut screw 4 is provided with a soft rubber pad 11.
[0035] By incorporating the soft rubber pad 11, the contact force between the undercut screw 4 and the guide rail surface can be effectively buffered during the clamping process, preventing scratches or indentations on the guide rail surface and protecting its integrity. Simultaneously, it increases friction, improves clamping stability, and avoids slippage or loosening caused by hard metal-to-metal contact, further enhancing the precision and safety of the guide rail connection.
[0036] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
