Description
Technical Field
[0001] This utility model relates to the field of profile technology, specifically to an elevator double door profile. Background Technology
[0002] Elevator doors are a crucial component of elevator systems, primarily responsible for isolating and opening / closing the elevator car from the floors. Elevator doors mainly come in the following types: single-leaf doors, double-leaf doors, center-parting doors, and folding doors.
[0003] Most elevator door panels are formed by extruding heated aluminum alloy through a mold. For example, patent document CN201911880192.4 discloses an automatic door panel assembly profile, which includes a crossbar profile and a retaining plate profile. A door panel glass mounting groove for installing the door panel glass and a motor shaft mounting groove for installing the motor shaft are formed between the crossbar profile and the retaining plate profile. The motor shaft is directly inserted into the motor shaft mounting groove, and the motor is not exposed, effectively improving aesthetics. Each door panel is driven by an independent motor, effectively preventing misalignment and incomplete closing.
[0004] The aforementioned patent document discloses a representative door leaf profile, but its long-term use has limitations. (For current applications of door leaf profiles, refer to patent document CN201180007291.5, which discloses the use of profiles in elevator door panels and elevator systems. The profiles can be used not only in horizontal sections but also in vertical areas. Specific locations can be found in this patent document titled "Elevator Door Panel and Elevator System," where...) Figure 1 The location of the support frame and the location of the reinforcing profile are recorded in the document, as follows:
[0005] 1. The profile structure design is not sophisticated enough, which is not conducive to extrusion molding. According to the technical solution provided in the above-mentioned patent documents, there is a protruding structure on the outside of the profile body. If the selected profile is thicker, the connection strength between the profile body and the protruding structure is sufficient during extrusion molding. However, if the selected profile is thinner, the connection between the profile body and the protruding structure is prone to breakage during extrusion molding.
[0006] 2. Poor space utilization. Again, taking the technical solution provided in the above patent literature as an example, the space utilization of the profile body itself is sufficient, but the protruding structure on the outside of the profile body will increase the material used by the entire profile, but the purpose it achieves is small, resulting in poor space utilization.
[0007] 3. Poor versatility.
[0008] Therefore, how to overcome the shortcomings of the existing technology mentioned above has become the subject of this utility model. Utility Model Content
[0009] This utility model provides an elevator double-door profile, which aims to solve the technical problems mentioned in the background art.
[0010] To achieve the above objectives, the technical solution adopted by this utility model is: an elevator double-leaf door profile, wherein the door profile includes a profile body;
[0011] Viewed from the cross-sectional perspective of the profile body, the profile body includes a first inclined plate, a second inclined plate, a first horizontal plate, and a second horizontal plate;
[0012] The first horizontal plate and the second horizontal plate are parallel and spaced apart. The first inclined plate and the second inclined plate are located on both sides of the first horizontal plate. The first inclined plate, the first horizontal plate, the second inclined plate and the second horizontal plate are connected end to end to form a frame structure. Furthermore, the first inclined plate and the second inclined plate are inclined in opposite directions to form a figure-eight shape, so that the first horizontal plate is shorter than the second horizontal plate.
[0013] The profile body has two corner sections at both ends of the second horizontal plate. One of the corner sections is an open end, which is defined by the distance between the ends of the first inclined plate and the second horizontal plate. The other corner section is a closed end, which is defined by the direct connection between the ends of the second inclined plate and the second horizontal plate.
[0014] The door panel profile further includes a first longitudinal plate, a second longitudinal plate, a third longitudinal plate, and a fourth longitudinal plate arranged in parallel from the open end to the closed end; wherein, one end of the first longitudinal plate is integrally connected to the end of the first inclined plate; the second longitudinal plate is connected between the first inclined plate and the second horizontal plate; the third longitudinal plate is connected between the first horizontal plate and the second horizontal plate; and the fourth longitudinal plate is connected between the end of the second inclined plate and the second horizontal plate.
[0015] The door panel profile also includes a sealing plate, one end of which is integrally connected to the middle of the second longitudinal plate, and the other end of which is integrally connected to the end of the first longitudinal plate away from the first inclined plate.
[0016] Thus, the sealing plate, the second longitudinal plate, and the second transverse plate together define an installation groove at the open end;
[0017] The second longitudinal plate and the third longitudinal plate together define a mating cavity within the frame structure;
[0018] The second longitudinal plate has a first screw fixing post on the side surface facing the first longitudinal plate; the first transverse plate has a second screw fixing post on the inner side surface facing the profile body and between the third longitudinal plate and the fourth longitudinal plate; the second transverse plate has a third screw fixing post on the inner side surface facing the profile body and between the fourth longitudinal plate and the second inclined plate.
[0019] Furthermore, the center line connecting the first screw fixing post, the second screw fixing post, and the third screw fixing post forms a triangular structure.
[0020] The following is an explanation of the relevant content in the above plan:
[0021] In the above scheme, the frame structure is trapezoidal, such as an isosceles trapezoid, which makes the extruded profile regular during the extrusion process and prevents defects from easily occurring. Secondly, the internal design of the frame structure can reduce the difficulty of profile forming and prevent structural breakage during extrusion.
[0022] In the above scheme, the mounting groove is mainly used for installing and fixing the glass.
[0023] In the above scheme, the insertion cavity is used to insert and install the L-shaped corner bracket connector, which serves to connect the X-axis and Y-axis profile corners, making it convenient, stable, and reliable.
[0024] In the above scheme, the triangular structure configuration can ensure high stability when the profiles are connected to the end caps.
[0025] In a further technical solution, a groove is provided on the surface of the second longitudinal plate, the groove being located within the mounting groove and facing the third longitudinal plate.
[0026] The groove is used to allow excess adhesive to escape during glass installation, facilitating air release and resulting in a tighter and smoother installation.
[0027] When the insertion cavity mates with the L-shaped corner bracket connector, it is necessary to ensure that the internal space of the insertion cavity matches the L-shaped corner bracket connector in order to achieve high stability. If the second longitudinal plate and the second transverse plate are not level, the space below the insertion cavity will be large, resulting in the L-shaped corner bracket connector shaking. Therefore, the groove is located in the mounting slot and faces the third longitudinal plate.
[0028] A further technical solution is that a fourth screw fixing post is provided on the surface of the second inclined plate near the second horizontal plate.
[0029] The fourth screw fixing post, the second screw fixing post, and the third screw fixing post have the same structure.
[0030] In a further technical solution, the fourth screw fixing post includes a first threaded sleeve portion with a notch, and the side wall of the first threaded sleeve portion is equipped with a thickened portion for positioning the first threaded sleeve portion.
[0031] The presence of the thickened portion can increase the stress strength of the first threaded sleeve portion, making it more stable and reliable. At the same time, it can also serve to fix the first threaded sleeve portion, that is, the first threaded sleeve portion and the second inclined plate are directly connected through the thickened portion (the fourth screw fixing post is used as an example here).
[0032] In a further technical solution, the first screw fixing post is a second screw sleeve with a notch.
[0033] A further technical solution involves setting the second longitudinal plate perpendicular to the sealing plate. This design ensures that the opening of the mounting groove is always U-shaped, allowing for quick fixation after glass insertion. If the second longitudinal plate is not perpendicular to the sealing plate, regardless of whether the opening is large and gradually decreases in size or small and gradually increases in size, the stability when fixing the glass is not as high as with a U-shaped groove.

Furthermore, both the first and second inclined plates feature a large inclined surface design, resulting in a grand and three-dimensional appearance. Under the same load-bearing requirements, this structure is more suitable for extrusion production. Attached Figure Description

[0044] The present invention will be further described below with reference to the accompanying drawings and embodiments:
[0045] Example: The present invention will be clearly described below with illustrations and detailed description. Any person skilled in the art who understands the examples of the present invention can make changes and modifications based on the technology taught in the present invention without departing from the spirit and scope of the present invention.
[0046] The terminology used herein is for the purpose of describing specific embodiments only and is not intended to limit the scope of this work. Singular forms such as “a,” “this,” “this,” “the,” and “the” as used herein also include plural forms.
[0047] See appendix Figures 1-2 As shown, an elevator double door profile includes a profile body 1;
[0048] Viewed from the cross-sectional angle of the profile body 1, the profile body 1 includes a first inclined plate 2, a second inclined plate 3, a first horizontal plate 4, and a second horizontal plate 5;
[0049] The first horizontal plate 4 and the second horizontal plate 5 are set parallel to each other and spaced apart. The first inclined plate 2 and the second inclined plate 3 are located on both sides of the first horizontal plate 4. The first inclined plate 2, the first horizontal plate 4, the second inclined plate 3 and the second horizontal plate 5 are connected end to end to form a frame structure. Furthermore, the first inclined plate 2 and the second inclined plate 3 are inclined in opposite directions to form a figure-eight shape, so that the first horizontal plate 4 is shorter than the second horizontal plate 5.
[0050] The profile body 1 has two corner sections at both ends of the second horizontal plate 5. One corner section is an open end, which is formed by the distance between the ends of the first inclined plate 2 and the second horizontal plate 5. The other corner section is a closed end, which is formed by the direct connection between the ends of the second inclined plate 3 and the second horizontal plate 5.
[0051] The door panel profile also includes a first longitudinal plate 6, a second longitudinal plate 7, a third longitudinal plate 8, and a fourth longitudinal plate 9 arranged in parallel from the open end to the closed end; wherein, one end of the first longitudinal plate 6 is integrally connected to the end of the first inclined plate 2; the second longitudinal plate 7 is connected between the first inclined plate 2 and the second horizontal plate 5; the third longitudinal plate 8 is connected between the first horizontal plate 4 and the second horizontal plate 5; and the fourth longitudinal plate 9 is connected between the end of the second inclined plate 3 and the second horizontal plate 5.
[0052] The door panel profile also includes a sealing plate 10, one end of which is integrally connected to the middle of the second longitudinal plate 7, and the other end is integrally connected to the end of the first longitudinal plate 6 away from the first inclined plate 2.
[0053] Thus, the sealing plate 10, the second longitudinal plate 7, and the second transverse plate 5 together define an installation groove 12 at the open end;
[0054] The second longitudinal plate 7 and the third longitudinal plate 8 together define a mating cavity 13 inside the frame structure;
[0055] The second longitudinal plate 7 has a first screw fixing post 14 on the side surface facing the first longitudinal plate 6; the first transverse plate 4 has a second screw fixing post 15 on the inner surface facing the profile body 1 and between the third longitudinal plate 8 and the fourth longitudinal plate 9; the second transverse plate 5 has a third screw fixing post 16 on the inner surface facing the profile body 1 and between the fourth longitudinal plate 9 and the second inclined plate 3.
[0056] Furthermore, the center line connecting the first screw fixing post 14, the second screw fixing post 15, and the third screw fixing post 16 forms a triangular structure.
[0057] In this invention, the frame structure can be trapezoidal, such as an isosceles trapezoid, so that the main body 1 of the extruded profile has a regular appearance and will not easily have defects. Secondly, the design inside the frame structure can reduce the difficulty of profile forming and prevent structural breakage during extrusion.
[0058] In this invention, the mounting groove 12 is mainly used for installing and fixing glass.
[0059] In this utility model, the insertion cavity 13 is used to insert and install the L-shaped corner bracket connector, which serves to connect the X-axis and Y-axis profile corners, making it convenient, stable, and reliable.
[0060] The triangular structure configuration ensures high stability when the profile body 1 is connected to the profile end cap.
[0061] In this utility model, the main body 1 of the profile has a robust design (i.e., all structures are set within a quadrilateral structure, eliminating concerns about breakage or other risks during installation and use) and is fully functional (it can accommodate both glass and L-shaped corner bracket connectors), making it a versatile material. Furthermore, both the first inclined plate 2 and the second inclined plate 3 feature a large inclined surface design, resulting in a grand and three-dimensional appearance. Under the same load-bearing requirements, this structure is more suitable for extrusion production.
[0062] In the specific design:
[0063] The angle between the second inclined plate 3 and the second horizontal plate 5 (i.e. the closed end) is 52 degrees;
[0064] The angle between the first horizontal plate 4 and the first inclined plate 2 is 130 degrees;
[0065] The angle between the first inclined plate 2 and the second longitudinal plate 7 is 140 degrees. Under the above-mentioned preferred angle design, it can be ensured that the structure of the profile body 1 is more suitable for extrusion production.
[0066] You can also refer to Figure 1 The top side wall of the mounting groove 12 is provided with an upwardly recessed groove, which can further serve the purpose of venting when applying sealant to the glass.
[0067] In some specific embodiments, the surface of the second longitudinal plate 7 is provided with a groove 17, which is located in the mounting groove 12 and faces the third longitudinal plate 8.
[0068] The groove 17 is used to allow excess adhesive to escape during glass installation, facilitating air release and making the installation more secure and flat.
[0069] When the insertion cavity 13 mates with the L-shaped corner bracket connector, it is necessary to ensure that the internal space of the insertion cavity 13 matches the L-shaped corner bracket connector in order to achieve high stability. If the second longitudinal plate 7 and the second transverse plate 5 are not level, the space below the insertion cavity 13 will be large, resulting in the L-shaped corner bracket connector shaking. Therefore, the groove 17 is located in the mounting groove 12 and is set towards the third longitudinal plate 8.
[0070] In some specific embodiments, a fourth screw fixing post 18 is provided on the surface of the second inclined plate 3 near the second horizontal plate 5.
[0071] The fourth screw fixing post 18, the second screw fixing post 15, and the third screw fixing post 16 have the same structure.
[0072] In some specific embodiments, the fourth screw fixing post 18 includes a first threaded sleeve portion 19 with a notch. A thickened portion 20 is installed on the side wall of the first threaded sleeve portion 19 for positioning. The presence of the thickened portion 20 increases the stress resistance of the first threaded sleeve portion 19, making it more stable and reliable. It also serves to fix the first threaded sleeve portion 19, meaning the first threaded sleeve portion 19 and the second inclined plate 3 are directly connected through the thickened portion 20 (the fourth screw fixing post 18 is used as an example here).
[0073] In some specific embodiments, the first screw fixing post 14 is a second screw sleeve portion 11 with a notch.
[0074] In some specific embodiments, the second longitudinal plate 7 is arranged perpendicularly to the sealing plate 10. This design ensures that the opening of the mounting groove 12 is always U-shaped, allowing for quick fixation after glass insertion. If the second longitudinal plate 7 is not perpendicular to the sealing plate 10, regardless of whether the opening is large and gradually decreases in size or small and gradually increases in size, the stability when fixing the glass is not as high as that of the U-shaped design.
[0075] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection 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 scope of protection of this utility model.
