Description

Technical Field

[0001] This utility model relates to the field of elevator technology, specifically to an elevator door panel anti-detachment structure. Background Technology

[0002] During elevator operation, the elevator door system plays a crucial role in safety. After prolonged use, wear and loosening between the door guide shoes and the sill can lead to derailment. Therefore, elevators typically require modification after reaching their service life to enhance safety. The elevator door is one of the most important and critical components for this modification. Currently, common elevator hall door modification solutions involve strengthening the door panel's rigidity or replacing the door feet with compatible ones to match the old sill. However, due to the wide variety of existing sills on the market, modification solutions also vary. When processing modification orders, solutions are usually limited to individual or single-type cases, making large-scale production impossible. Furthermore, the modification solution of replacing the door feet presents a problem: the new guide shoes cannot guarantee the door panel's impact resistance when matched with the old sill. Utility Model Content

[0003] In view of this, in order to overcome the shortcomings of the prior art, this utility model provides an improved elevator door panel anti-detachment structure, which can be directly applied to the sill of existing elevator door panels to be modified, so that the interface between the modified new door panel and the sill is unified, while ensuring the anti-collision performance of the door panel.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An elevator door panel anti-detachment structure includes a guide door foot and a fixing member. The upper end of the guide door foot is fixedly connected to the bottom of the elevator door panel. The fixing member is installed in the sill of the elevator door panel. The length direction of both the guide door foot and the fixing member is parallel to the length direction of the sill. The fixing member has a receiving groove. The bottom of the guide door foot includes an anti-detachment hook and a protective block wrapped around the anti-detachment hook. The protective block is used to cooperate with the receiving groove and the top of the fixing member. The anti-detachment hook is used to cooperate with the top of the fixing member when the protective block is worn.

[0006] By installing fixing components and guide feet, and embedding the fixing components in the existing sill on-site while connecting the guide feet to the bottom of the elevator door panel, the lower part of the modified door panel can be prevented from detaching by utilizing the cooperation between the protective block on the guide feet and the fixing components. When the protective block wears down, the internal anti-detachment hook can also cooperate with the fixing components to ensure that the door panel remains in its original position when impacted. Furthermore, this anti-detachment structure can be directly applied to the sill of existing elevator door panels to be modified, making the interface between the modified door panel and the sill uniform and perfectly matched, which is conducive to large-scale production.

[0007] According to a preferred embodiment of the present invention, the length of the fixing member is equal to the length of the sill.

[0008] According to a preferred embodiment of the present invention, the fixing member includes a fixing plate and a top plate and a bottom plate located at the top and bottom ends of the fixing plate, respectively. The top plate and the bottom plate are both perpendicular to the fixing plate, and the length direction of the fixing plate is parallel to the length direction of the sill.

[0009] According to a preferred embodiment of the present invention, the top plate and the bottom plate are both located on the side of the fixed plate close to the protective block, the sill has a sliding groove extending downward from its top surface, the side of the fixed plate away from the protective block is fitted with the side wall of the sliding groove, and the bottom plate is fixedly connected to the bottom of the sliding groove.

[0010] According to a preferred embodiment of the present invention, the width of the top plate is smaller than the width of the bottom plate, and the top plate, the fixing plate and the bottom plate together enclose the receiving groove.

[0011] According to a preferred embodiment of this utility model, the height of the fixing member is less than the height of the slide groove, the sum of the thickness of the base plate and the width of the fixing plate is less than or equal to the width of the slide groove, and the height of the receiving groove is greater than the height of the protective block. This ensures that the protective block can be accommodated in the receiving groove, and that the protective block and the top plate of the fixing member cooperate with each other, with the top plate limiting the position of the protective block to prevent it from detaching.

[0012] According to a preferred embodiment of this utility model, the guide door foot further includes a connecting plate located in the middle of the protective block. The top of the connecting plate is fixedly connected to the bottom of the elevator door panel. Notches are provided at both ends of the bottom of the connecting plate, and the anti-detachment hooks are correspondingly provided with the notches. In some embodiments of this utility model, the protective block is made of rubber. When the protective block is not worn, it completely covers the outside of the anti-detachment hooks, and there is no interaction between the anti-detachment hooks and the fixing components. Only when the protective block is worn down and the anti-detachment hooks are exposed will the anti-detachment hooks cooperate with the fixing components to prevent the door panel from detaching.

[0013] According to a preferred embodiment of this utility model, the bottom of the anti-disengagement hook is fixedly connected to the bottom of the notch, and the anti-disengagement hook is inclined downwards from its top edge towards the fixing plate. This arrangement is to ensure that the anti-disengagement hook can hook onto the top plate of the fixing member, ensuring a tight fit between the two.

[0014] According to a preferred embodiment of this utility model, there is a first gap between the side of the connecting plate near the top plate and the side of the top plate near the connecting plate; the distance between the side of the protective block near the fixing plate and the side of the connecting plate near the fixing plate is greater than the first gap; the width of the protective block is greater than the distance from the side of the top plate away from the fixing plate to the sidewall of the slide groove away from the fixing plate; the orthographic projection of the anti-detachment hook on the bottom plate coincides with the orthographic projection of the top plate on the bottom plate. These arrangements are all to ensure that the protective block and the anti-detachment hook can effectively cooperate with the top plate of the fixing component under different conditions, so as to ensure that the door panel can remain in its original position under normal conditions or when subjected to impact, preventing the door panel from detaching and protecting passenger safety.

[0015] According to a preferred embodiment of the present invention, the height of the notch is greater than the length of the anti-detachment hook, and the side of the anti-detachment hook near the opening of the notch is flush with the side of the connecting plate.

[0016] Compared with existing technologies, the advantages of this utility model are as follows: The elevator door panel anti-detachment structure of this utility model, by setting a fixing component and a guide foot, and installing the fixing component in the existing sill on site while connecting the guide foot to the bottom of the elevator door panel, utilizes the cooperation between the protective block on the guide foot and the fixing component to achieve the lower anti-detachment function of the modified door panel. When the protective block wears down, the internal anti-detachment hook can also cooperate with the fixing component to ensure that the door panel remains in its original position when impacted. Furthermore, this anti-detachment structure can be directly applied to the sill of existing elevator door panels to be modified, making the interface between the modified door panel and the sill uniform and perfectly matched, greatly increasing applicability, effectively reducing elevator modification costs, and facilitating large-scale production.

[0024] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0025] See Figures 1 to 4 An elevator door panel anti-detachment structure according to this embodiment includes a guide door foot 2 and a fixing member 3. The upper end of the guide door foot 2 is fixedly connected to the bottom of the elevator door panel 1. The sill 4 is located below the door panel 1. The sill 4 has a sliding groove 41 extending downward from its top surface. The fixing member 3 is installed in the sliding groove 41 of the sill 4. The bottom of the guide door foot 2 cooperates with the fixing member 3.

[0026] The length direction of the guide door foot 2 and the length direction of the fixing member 3 are both parallel to the length direction of the sill 4. In this embodiment, the lengths of the guide door foot 2 and the fixing member 3 are equal to the length of the sill 4.

[0027] Furthermore, such as Figure 1 , Figure 3 and Figure 4As shown, the height of the fixing member 3 is less than the height of the chute 41. The fixing member 3 includes a fixing plate 31 and a top plate 32 and a bottom plate 33 located at the top and bottom ends of the fixing plate 31, respectively. The top plate 32 and the bottom plate 33 are both perpendicular to the fixing plate 31, and the length direction of the fixing plate 31 is parallel to the length direction of the sill 4. The top plate 32 and the bottom plate 33 are both located on the side of the fixing plate 31 closest to the protective block 23. The outer side of the fixing plate 31 is in contact with the side wall of the chute 41, and the bottom plate 33 is fixedly connected to the bottom of the chute 41 so that the fixing member 3 is fixed in the chute 41 of the sill 4.

[0028] The top plate 32, the fixed plate 31 and the bottom plate 33 together form a receiving groove 34 for cooperating with the guide door foot 2. The width of the top plate 32 is smaller than the width of the bottom plate 33, and the sum of the thickness of the bottom plate 33 and the width of the fixed plate 31 is less than or equal to the width of the slide groove 41.

[0029] Furthermore, such as Figure 2 As shown, the guide door foot 2 includes a connecting plate 21, an anti-detachment hook 22, and a protective block 23 wrapped around the anti-detachment hook 22. In this embodiment, the protective block 23 is made of rubber. The anti-detachment hook 22 and the protective block 23 are both located at the bottom of the connecting plate 21, and the connecting plate 21 is located in the middle of the protective block 23. The top of the connecting plate 21 is used to fix it to the bottom of the elevator door panel 1. Notches 211 are provided at both ends of the bottom of the connecting plate 21. The notches 211 are opened inward from the side of the connecting plate 21 in the width direction. An anti-detachment hook 22 is fixedly installed at each notch 211. The bottom of the anti-detachment hook 22 is fixedly connected to the bottom of the notch 211. The height of the notch 211 is greater than the length of the anti-detachment hook 22. The side of the anti-detachment hook 22 near the opening of the notch 211 is flush with the side of the connecting plate 21.

[0030] Specifically, such as Figure 4 As shown, the anti-disengagement hook 22 is inclined downwards from its top edge towards the fixing plate 31, and the orthographic projection of the anti-disengagement hook 22 on the base plate 33 coincides with the orthographic projection of the top plate 32 on the base plate 33. Figure 3As shown, the height of the receiving groove 34 is greater than the height of the protective block 23. There is a first gap d between the side of the connecting plate 21 near the top plate 32 and the side of the top plate 32 near the connecting plate 21. The distance between the side of the protective block 23 near the fixing plate 31 and the side of the connecting plate 21 near the fixing plate 31 is greater than the first gap d. The width of the protective block 23 is greater than the distance from the side of the top plate 32 away from the fixing plate 31 to the sidewall of the slide 41 away from the fixing plate 31. These features are designed to ensure that the protective block 23 and the anti-detachment hook 22 can effectively cooperate with the top plate 32 of the fixing member 3 under different conditions. This ensures that under normal conditions, when the protective block 23 is not worn, the door panel 1 is completely covered by the anti-detachment hook 22, and the protective block 23 can cooperate with the top plate 32 so that the top plate 32 can hold the protective block 23, keeping the door panel 1 in its original position. When the protective block 23 is worn and the anti-detachment hook 22 is exposed, the anti-detachment hook 22 can hook the top plate 32 of the fixing member 3 when the door panel 1 is impacted, ensuring a tight fit between the two, so that the door panel 1 can remain in its original position and prevent the door panel 1 from detaching, thereby protecting passenger safety.

[0031] Compared to existing technologies, the elevator door panel anti-detachment structure of this utility model provides an anti-detachment structure without altering the existing sill 4. Its simple structure and ease of implementation are achieved by installing the fixing component 3 into the existing sill 4 on-site and connecting the guide door foot 2 to the bottom of the elevator door panel 1. The cooperation between the protective block 23 on the guide door foot 2 and the fixing component 3 enables the lower part of the modified door panel 1 to be anti-detached. When the protective block 23 wears down, the internal anti-detachment hook 22, in cooperation with the fixing component 3, can prevent the door panel 1 from detaching when impacted. This anti-detachment structure can be directly applied to the existing sill 4 of the elevator door panel 1 to be modified, unifying the interface between the modified door panel 1 and the sill 4, ensuring a perfect match, greatly increasing applicability, effectively reducing elevator modification costs, and facilitating large-scale production.

[0032] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the protection scope of this utility model.
