Abstract
Description
Technical Field
[0001] This utility model relates to the field of elevator component technology, specifically to a quick-release inspection cover for elevator doors. Background Technology
[0002] For swing elevator doors, one side of the door leaf is a pivot, with both the upper and lower ends of the pivot rotatably mounted on the door frame to meet the swing-opening requirement. Additionally, for automatic swing elevator doors, a drive motor is typically installed inside the door frame. The output shaft of the drive motor is connected to the pivot of the door leaf, thereby enabling the automatic opening and closing of the door leaf. For example, patent CN212356170U discloses a swing elevator door whose door frame includes an upper door frame, a lower door frame, and two side door frames. The left and right door frames are rotatably connected to the upper and lower door frames via upper and lower pivots, respectively, with the upper pivots extending beyond the upper door frame. A reduction motor is fixed above the upper door frame and connected to the upper pivot of one side door via a coupling, used to drive the side door to rotate synchronously, thus controlling the opening and closing of the elevator door.
[0003] Because the power structures used for opening and closing elevator doors, such as the drive motor, are all located within the door frame, and to ensure the aesthetics of the elevator door, a mounting cavity is usually provided in the door frame, where the drive motor and other structures are concealed and covered by a cover plate, achieving a hidden installation of the drive motor and other structures within the door frame. Although the above structure meets the usage requirements of elevator doors, the opening and closing of elevator doors mainly relies on the drive motor, safety locks, and other structures, and each opening and closing of the elevator door requires the operation of these structures. This makes the drive motor, safety locks, and other structures vulnerable to damage, requiring maintenance and repair after a period of use. In addition, the installation of the door frame cover plate in the mounting cavity of the door frame is usually achieved by screw connection. That is, holes need to be drilled in the cover plate, and screws are screwed into the structure inside the door frame after passing through the holes in the cover plate. Disassembly and assembly require tools such as screwdrivers, and it is not a true quick-release structure, causing inconvenience for later maintenance and also deteriorating the overall integrity of the cover plate surface, affecting its aesthetics. Summary of the Invention
[0004] To address the aforementioned problems in the existing technology, this invention aims to provide a quick-release inspection cover for elevator doors. The cover has a retaining edge and a retaining head at the bottom and top of a door frame beam with an installation cavity, respectively. Simultaneously, a retaining strip and a retaining seat are provided at the bottom and top of one side of the cover body, respectively, to engage with the retaining edge and retaining head. This allows the cover body to be installed on the door frame beam by engaging the bottom of the cover body with the bottom of the door frame beam through the retaining strip and retaining edge, and engaging the top of the cover body with the top of the door frame beam through the retaining seat and retaining head. This achieves a snap-fit installation of the cover body on the door frame beam, allowing for tool-free installation and removal, meeting the requirements for quick disassembly, facilitating subsequent maintenance, and maintaining the integrity of the cover body surface for aesthetic purposes.
[0005] The specific technical solution is as follows:
[0006] A quick-release inspection cover for elevator doors is installed on a door frame beam, the door frame beam having an installation cavity. The cover includes a cover body that covers the opening of the installation cavity on the door frame beam. A mounting seat and a mounting strip are respectively provided at the top and bottom of one side of the cover body. Additionally, a locking head and a locking edge are respectively provided at the top and bottom of the door frame beam within the installation cavity. The locking head selectively engages with the mounting seat, and the locking edge and the mounting strip selectively engage with each other.
[0007] The aforementioned quick-release inspection cover for elevator doors includes a clip head comprising a fixed end and a snap-fit end. The fixed end is installed on the inner wall of the cavity opening of the mounting cavity, one end of the snap-fit end is connected to the fixed end, and the other end of the snap-fit end extends outward toward the cavity opening of the mounting cavity.
[0008] The aforementioned quick-release inspection cover for elevator doors further includes an adapter seat, which is disposed between the clip head and the inner wall of the mounting cavity. The adapter seat includes a first fixing part and a second fixing part, which are arranged at an angle. The first fixing part is fixedly installed on the top wall of the mounting cavity, and the fixed end of the clip head is installed on the second fixing part.
[0009] The aforementioned quick-release inspection cover for elevator doors has a large end near the cavity opening and a small end near the fixed end of the clip head. The clip seat includes a mounting base and two clip blocks. The mounting base is fixedly installed on the cover body. Two clip blocks are spaced apart on the mounting base, and a slot is formed between the two clip blocks. The clip head engages into the slot between the two clip blocks.
[0010] The aforementioned quick-release inspection cover for elevator doors includes a horizontally extending mounting strip on one side of the cover body, the mounting strip being fixed to the cover body, and a mounting bracket being installed on the mounting strip.
[0011] The aforementioned quick-release inspection cover for elevator doors has a clip protruding vertically upward at the bottom of the mounting cavity, one side of the clip is fixed to the cover body, and the end of the clip away from the cover body is bent downward to form a barb.
[0012] The aforementioned quick-release inspection cover for elevator doors, wherein the card holder or card head is made of magnetic material, and the card head or card holder is made of magnetic attraction material.
[0013] The positive effects of the above technical solution are:
[0014] The aforementioned quick-release inspection cover for elevator doors features a locking head and a locking edge at the top and bottom of the mounting cavity within the door frame beam, respectively. Additionally, a locking seat and a locking strip are located at the top and bottom of one side of the cover body. When the cover body is installed at the opening of the mounting cavity in the door frame beam, the lower part of the cover body engages the locking edge via the locking strip, while the upper part engages the locking head via the locking seat. This achieves a snap-fit connection between the cover body and the door frame beam, allowing for quick disassembly without the need for tools. This makes operation more convenient and facilitates the maintenance and repair of the relevant structures within the mounting cavity. Attached Figure Description

[0020] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following embodiments are provided in conjunction with the appendix. Figure 1 To be continued Figure 4The technical solution provided by this utility model is described in detail, but the following content is not intended to limit this utility model.
[0021] Figure 1 This is a structural diagram of an embodiment of the quick-release inspection cover for elevator doors according to the present invention; Figure 2 This is a diagram illustrating the connection structure of the clip head and clip seat for a quick-release inspection cover for elevator doors according to this utility model. Figure 1 and Figure 2 As shown, the quick-release inspection cover for elevator doors provided in this embodiment is installed on the door frame beam 1. At this time, the door frame beam 1 has an installation cavity 11, which provides installation space for structures such as drive motors and safety locks, thereby realizing the concealed installation of structures such as drive motors and safety locks in the door frame beam 1.
[0022] Specifically, the quick-release maintenance cover for elevator doors provided in this embodiment includes a cover body 2, and the cover body 2 covers the opening of the mounting cavity 11 on the door frame beam 1, thereby covering the opening of the mounting cavity 11 and improving aesthetics. Furthermore, a locking seat 21 and a locking strip 22 are respectively provided at the top and bottom of one side of the cover plate body 2. The locking seat 21 and the locking strip 22 form a locking structure at the top and bottom of one side of the cover plate body 2. At the same time, a locking head 12 and a locking edge 13 are respectively provided at the top and bottom of the door frame beam 1 and located in the mounting cavity 11. The locking head 12 and the locking edge 13 form a matching structure corresponding to the locking structure at the top and bottom of the cavity opening of the mounting cavity 11 of the door frame beam 1. At this time, the locking head 12 selectively engages with the locking seat 21, and the locking edge 13 selectively engages with the locking strip 22, thereby realizing the locking installation of the cover plate body 2 on the door frame beam 1. This meets the use requirements of quick disassembly of the cover plate body 2, so that when it is necessary to maintain and repair the structure inside the mounting cavity 11 of the door frame beam 1, the cover plate body 2 can be disassembled and installed from the door frame beam 1 without the aid of tools. The operation is more convenient, and at the same time, the integrity of the surface of the cover plate body 2 is maintained, ensuring aesthetics.
[0023] Figure 3 This is a structural diagram of the door frame beam of a quick-release inspection cover for elevator doors according to this utility model. Figures 1 to 3 As shown, the latch 12 includes a fixed end 121 and a latching end 122. The fixed end 121 is installed on the inner wall of the cavity opening of the mounting cavity 11. One end of the latching end 122 is connected to the fixed end 121, and the other end of the latching end 122 extends outward toward the cavity opening of the mounting cavity 11. The extension of the latching end 122 provides a condition for subsequent direct contact with the latch seat 21 on one side of the cover body 2 installed at the cavity opening of the mounting cavity 11. Preferably, the fixed end 121 and the latching end 122 are an integral structure, which has better integrity and higher structural strength, thereby making the cover body 2 more stable after installation.
[0024] More specifically, an adapter 14 is provided between the clip 12 and the inner wall of the mounting cavity 11. The adapter 14 serves as a support structure for mounting the clip 12 onto the inner wall of the mounting cavity 11. The adapter 14 includes a first fixing part 141 and a second fixing part 142, which are arranged at an angle, allowing them to have different orientations. During installation, the first fixing part 141 is fixedly mounted to the top wall of the mounting cavity 11, and the fixing end 121 of the clip 12 is mounted on the second fixing part 142. The adapter 14 enables the clip 12 to be mounted on the top wall of the mounting cavity 11, maximizing the internal height of the mounting cavity 11 while ensuring the clip 12 is installed, allowing for the arrangement of more structures within the mounting cavity 11. Furthermore, it allows the clip 12 to face horizontally towards the opening of the mounting cavity 11, facilitating subsequent engagement with the clip seat 21.
[0025] More specifically, the end of the snap-fit end 122 of the snap-fit head 12 that is closer to the opening of the mounting cavity 11 is the large end, and the end that is closer to the fixing end 121 is the small end, so that the snap-fit end 122 of the snap-fit head 12 forms an inverted triangular structure. The closer it is to the opening of the mounting cavity 11, the larger its volume is, which provides conditions for subsequently restricting the snap-fit seat 21 and realizing the accidental anti-dislodgement of the snap-fit seat 21. The card holder 21 includes a mounting base 211 and two locking blocks 212. The mounting base 211 is fixedly installed on the cover plate body 2. Two locking blocks 212 are spaced apart on the mounting base 211, and a locking gap 213 is formed between the two locking blocks 212. This allows the locking end 122 of the locking head 12 to be inserted into the locking gap 213 between the two locking blocks 212 when the cover plate body 2 is subsequently installed on the door frame beam 1. Furthermore, the two sides of the larger end of the locking end 122 press against the two locking blocks 212, thereby realizing the locking connection between the card holder 21 and the locking head 12. Conversely, pulling the card holder 21 in the opposite direction can separate the card holder 21 and the locking head 12, meeting the requirements for quick disassembly.
[0026] Figure 4 This is a structural diagram of the cover body of a quick-release inspection cover for elevator doors according to this utility model. Figure 1 , Figure 2 as well as Figure 4 As shown, a horizontally extending mounting strip 23 is provided on one side of the cover plate body 2. The mounting strip 23 is fixed to the cover plate body 2, expanding the side space of the cover plate body 2 and facilitating the installation of the mounting bracket 21 on the cover plate body 2. At the same time, by installing the mounting bracket 21 on the mounting strip 23, the mounting strip 23 provides an installation carrier for the mounting bracket 21, thereby changing the installation direction of the mounting bracket 21. This allows the mounting head 12 to be inserted into the mounting slot 213 from the side of the mounting bracket 21 when the cover plate body 2 is subsequently installed on the door frame beam 1, avoiding the problem that the mounting head 12 would not be able to be inserted due to insufficient depth of the mounting slot 213.
[0027] More specifically, the retaining edge 13 protrudes vertically upwards from the bottom of the mounting cavity 11, forming a protruding blocking structure at the bottom of the cavity opening of the mounting cavity 11. Simultaneously, one side of the retaining strip 22 is fixed to the cover plate body 2, and the end of the retaining strip 22 facing away from the cover plate body 2 is bent downwards to form a barb 221. This allows the retaining strip 22 and the retaining edge 13 to be hooked together when the cover plate body 2 is installed at the opening of the mounting cavity 11, thus achieving a snap-fit connection and meeting the quick-release requirement between the cover plate body 2 and the door frame beam 1.
[0028] In a preferred embodiment, the card holder 21 or the card head 12 is made of magnetic material, and the card head 12 or the card holder 21 is made of magnetic material. That is, when the card holder 21 is made of magnetic material, the card head 12 is made of magnetic material, and vice versa. This allows for magnetic connection when the card head 12 is inserted into the card holder 21 through the cooperation of the magnetic material and the magnetic material. This also allows for easy connection and disassembly of the card holder 21 and the card head 12, meeting the requirement for quick disassembly. Furthermore, it improves the reliability of the connection between the card holder 21 and the card head 12, preventing the cover plate body 2 from accidentally falling off the door frame beam 1 during elevator operation, resulting in a more rational structural design.
[0029] The quick-release maintenance cover for elevator doors provided in this embodiment includes a cover body 2, a retaining edge 13, a retaining strip 22, a retaining head 12, and a retaining seat 21. The retaining head 12 and retaining edge 13 are respectively provided at the top and bottom of the mounting cavity 11 of the door frame beam 1. Simultaneously, the retaining seat 21 and retaining strip 22 are respectively provided at the top and bottom of one side of the cover body 2. This allows the cover body 2 to be installed at the opening of the mounting cavity 11 of the door frame beam 1, where the retaining strip 22 can hold the retaining edge 13, and the retaining head 12 can be engaged with the retaining seat 21. This achieves a snap-fit connection between the cover body 2 and the door frame beam 1, enabling disassembly and assembly without tools, meeting the quick-release requirement, facilitating maintenance and repair of the relevant structures within the mounting cavity 11 of the door frame beam 1, and making operation more convenient.
[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
