[0020] The following is a detailed description of the implementation of the utility model in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the utility model, but cannot be used to limit the scope of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Combination Figure 1 , Figure 2 and Figure 3As shown, an adjustable elevator door slider structure includes an elevator door panel 1, the bottom of which is suspended above a sill 2. The elevator door panel 1 serves as an entrance and exit passage for the elevator, and the bottom is not directly in contact with the ground, but is suspended above the sill 2. A guide groove 3 is provided on the sill 2. The sill 2 serves as a fixed structure below the elevator door panel 1, which not only plays a supporting role, but is also designed with a guide groove 3, which is crucial for the guidance and positioning of the elevator door panel 1.

[0022] The bottom of the elevator door panel 1 is symmetrically provided with an eight-shaped mounting hole 4, which not only enhances the stability of the structure but also facilitates the subsequent installation and adjustment of the slider assembly 5.

[0023] The mounting holes 4 are all equipped with slider assemblies 5. The top of the slider assemblies 5 is fastened to the elevator door panel 1 by bolts passing through the mounting holes 4. The top of the slider assemblies 5 is designed with holes matching the bolts. The bolts pass through the mounting holes 4 and are fastened to the elevator door panel 1, thereby realizing a stable connection between the slider assemblies 5 and the elevator door panel 1. The top of the slider assemblies 5 ensures that the slider assemblies 5 will not fall off or become loose during the operation of the elevator.

[0024] The bottom end of the slider assembly 5 is inserted into the guide groove 3 and slidably connected with the inner walls on both sides of the guide groove 3. This not only reduces the friction resistance of the elevator door panel 1 during operation, but also enables the elevator door to be opened and closed smoothly along the track of the guide groove 3. More importantly, the design of the slider assembly 5 allows for fine-tuning when necessary to ensure that the gap between the elevator door panel 1 and the sill 2 is always maintained within a safe and reasonable range.

[0025] The adjustable elevator door slider structure also has the advantage of being easy to maintain and replace. When the slider assembly 5 is worn or damaged due to long-term use, the slider assembly 5 can be easily removed from the mounting hole 4 and replaced by simply loosening the bolts, which greatly reduces maintenance costs and time costs.

[0026] Combination Figure 2 , Figure 3 and Figure 4 As shown, the slider assembly 5 includes a fixing member 51 disposed at the bottom of the elevator door panel 1, and the fixing member 51 is connected to the bottom of the elevator door panel 1, ensuring the stability of the slider assembly 5 during the operation of the elevator. A connecting rod 52 is disposed at the bottom of the fixing member 51, and the connecting rod 52 ensures that the slider assembly 5 slides smoothly in the guide groove 3. A sliding block 53 is sleeved on the connecting rod 52, and the sliding block 53 ensures that the elevator door panel 1 can move easily and smoothly along the track of the guide groove 3. The surface of the sliding block 53 is in sliding contact with the inner walls on both sides of the guide groove 3.

[0027] When the sliding block 53 is severely worn due to long-term use, the sliding block 53 can be easily removed from the connecting rod 52 and replaced by simply loosening the fasteners on the fixing member 51, which greatly reduces the maintenance cost and time cost.

[0028] Combination Figure 2 , Figure 3 and Figure 4 As shown, a bolt hole 511 is provided at the center of the top of the fixing member 51, and the bolt hole 511 ensures that the bolt can pass through the mounting hole 4 tightly and be firmly fixed on the elevator door panel 1, thereby preventing the loosening or falling off during the operation of the elevator. The slider assembly 5 can be firmly connected to the bottom of the elevator door panel 1 by bolts.

[0029] The connecting rod 52 is arranged at a side of the bottom of the fixing member 51 that is deviated from the center. The connecting rod 52 is not simply arranged at the center of the circle at the bottom of the fixing member 51, but is deviated from the center of the circle. This not only allows the connecting rod 52 to more flexibly adapt to the shape and size of the guide groove 3, but also can reduce the vibration and noise of the elevator door panel 1 during the opening and closing process to a certain extent.

[0030] Combination Figure 1 , Figure 2 and Figure 3 As shown, the mounting hole 4 is a long waist hole. Designing the mounting hole 4 as a long waist hole not only increases the flexibility of the mounting hole 4, but also provides more adjustment space for the installation of the fixing member 51.

[0031] The extension direction of the mounting hole 4 intersects with the extension direction of the guide groove 3 at an inclined angle. The characteristic of the long waist hole is that its extension direction is not parallel to the surface of the elevator door panel 1, but forms a certain inclined angle with the extension direction of the guide groove 3. By adjusting the position of the fixing member 51 in the mounting hole 4, the installation angle of the slider assembly 5 on the elevator door panel 1 can be fine-tuned.

[0032] When the elevator door is worn or deviated after long-term operation, it is only necessary to loosen the bolts, adjust the position of the fixing member 51 in the mounting hole 4, and then re-tighten the bolts to achieve fine adjustment of the running track of the elevator door, thereby ensuring the smooth operation and safety of the elevator door. This not only improves the convenience and flexibility of the installation of the slider assembly 5, but also provides more possibilities for the maintenance and adjustment of the elevator door.

[0033] The fixing member 51 is slidably installed on the elevator door panel 1 by passing the bolt through the mounting hole 4. During the installation process, the bolt first passes through the mounting hole 4, and the position of the bolt in the mounting hole 4 is adjusted by the position of the sliding block 53 in the guide groove 3, so that the bolt is aligned with the bolt hole 511 on the fixing member 51 connected to the sliding block 53, and then the bolt is screwed into the bolt hole 511 of the fixing member 51 to fix the fixing member 51 on the elevator door panel 1.

[0034] Combination Figure 1 , Figure 2 and Figure 3 As shown, in order to further enhance the structural strength and stability of the elevator door panel 1 , a first sealing plate 6 is provided on the elevator door panel 1 , and the first sealing plate 6 ensures the stability and reliability of the slider assembly 5 .

[0035] A second sealing plate 7 is arranged above the first sealing plate 6 in parallel, and the second sealing plate 7 provides additional reinforcement and support for the elevator door panel 1. The mounting hole 4 is fixedly arranged on the first sealing plate 6. In the process of fixing the mounting hole 4, by adopting the long waist hole design and the sliding installation technology, the fixing member 51 can be fine-tuned in the mounting hole 4, thereby ensuring that the installation angle and position of the slider assembly 5 on the elevator door panel 1 are in the best state. This not only improves the running stability and safety of the elevator door, but also provides more convenience and possibilities for the maintenance and adjustment of the elevator.

[0036] Combination Figure 1 , Figure 2 and Figure 3 As shown, the distance between the bottom of the first sealing plate 6 and the bottom end of the elevator door panel 1 is greater than or equal to the height of the fixing member 51.

[0037] Specifically, the distance between the bottom of the first cover plate 6 and the bottom end of the elevator door panel 1 is set to be greater than or equal to the height of the fixing member 51. This ensures that when the fixing member 51 is fixed to the first cover plate 6 by passing the bolts through the mounting holes 4, the bottom of the fixing member 51 will not interfere with the bottom end of the elevator door panel 1. This ensures that the fixing member 51 can always be firmly connected to the first cover plate 6 despite the slight deformation or vibration that may occur during the operation of the elevator door panel 1, and will not be loosened or damaged due to friction or collision with the bottom end of the door panel.

[0038] During the actual installation or maintenance process, if it is necessary to fine-tune the position or angle of the slider assembly 5 to ensure that the gap between the elevator door panel 1 and the sill 2 remains consistent, this spacing allows technicians to fine-tune the slider assembly 5 by adjusting the position of the fixing member 51 in the mounting hole 4 without removing the elevator door panel 1, thereby greatly simplifying the installation and adjustment process and improving work efficiency.

[0039] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the height of the sliding block 53 is smaller than the height of the inner walls on both sides of the guide groove 3 .

[0040] Specifically, the height of the sliding block 53 is less than the height of the inner walls on both sides of the guide groove 3, which ensures that the sliding block 53 can slide smoothly in the guide groove 3. When the elevator door is opened or closed, the sliding block 53 moves along the track of the guide groove 3, and will not rub or collide with the top of the guide groove 3 due to excessive height. The resistance and noise during the operation of the elevator door panel 1 are reduced, and the riding comfort of the elevator is improved.

[0041] During the operation of the elevator door, if the height of the sliding block 53 is too large, once it collides with the top of the guide groove 3, the elevator door panel 1 may be stuck or damaged, and in serious cases, may even cause a safety accident. Therefore, setting the height of the sliding block 53 to be less than the height of the inner walls on both sides of the guide groove 3 can effectively avoid such potential safety hazards.

[0042] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the fixing member 51, the connecting rod 52 and the sliding block 53 are all made of metal. The fixing member 51, the connecting rod 52 and the sliding block 53 are made of metal, which is an important choice in the structural design of the adjustable elevator door slider. This material selection ensures the strength, durability and performance of the entire structure, and provides a solid guarantee for the smooth operation and safety of the elevator door panel 1. At the same time, by selecting a suitable metal material and performing appropriate surface treatment, the corrosion resistance, processability and service life of these components can be further improved.

[0043] The present invention is a preferred specific implementation manner, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical scheme and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
