Description

Technical Field

[0001] This invention relates to the field of door and window technology, and in particular to a linkage door hanging structure and a linkage door. Background Technology

[0002] In existing technology, the installation steps for interlocking doors are generally as follows: First, install the winding wheel device onto the mounting box; second, install the mounting box onto the pulleys in the upper guide rail; third, install the door leaf onto the mounting box; fourth, wind a steel wire rope or belt rope between the two winding wheel devices; fifth, install other connecting parts and decorative parts. However, the installation of the steel wire rope or belt rope is very inconvenient, labor-intensive, and costly.

[0003] Therefore, there is a need to provide a linkage door hanging structure that can improve the installation steps of linkage doors. Summary of the Invention

[0004] In order to overcome at least one of the defects described in the prior art, the present invention provides a linkage door hanging structure.

[0005] The technical solution adopted by this invention to solve its problem is:

[0006] A linkage door hanging structure includes two sets of door frame hanging boxes for installation on the top of the door leaf; a connecting device for connecting the two door frame hanging boxes; and two sets of winding wheel devices respectively disposed on the two door frame hanging boxes.

[0007] The linkage door hanging structure provided by this invention connects two door frame hanging boxes via a connecting device to determine the relative distance between the two door frame hanging boxes. Then, a steel wire rope or belt rope is wound between two sets of winding wheel devices. The linkage door hanging structure is then installed onto the pulleys in the upper guide rail, and finally, the linkage door hanging structure is fixedly connected to the door leaf. Using this linkage door hanging structure simplifies the installation process of linkage doors, facilitates the installation and fixing of steel wire ropes or belt ropes, speeds up installation, reduces installation difficulty, and saves labor costs.

[0008] Furthermore, the connecting device includes two slidingly inserted and fastened adjusting rods, each of which is connected to a door frame hanging box via a connector.

[0009] Therefore, the relative distance between the two winding wheel devices is adjusted and fixed by adjusting the two-phase sliding plug-in locking rod to adapt to door leaves of different widths, reduce the types and quantities of accessories, and save costs.

[0010] Furthermore, the connector is integrally formed with the door frame hanging box.

[0011] Furthermore, the cross-section of the adjusting rod is U-shaped, including a bottom edge, a first vertical edge and a second vertical edge connected to both ends of the bottom edge, and a hook-shaped fastener is provided on the bottom edge. When the two adjusting rods are slidably inserted into each other, the two hook-shaped fasteners are engaged.

[0012] Furthermore, the bottom edge, the first vertical edge, the second vertical edge, and the hook-shaped fastener are integrally formed.

[0013] Therefore, the interlocking of the two hook-shaped fasteners ensures the sliding connection of the two adjusting rods, and the overall strength of the one-piece molded adjusting rod is better, which also facilitates production.

[0014] Furthermore, the cross-section of the adjusting rod is H-shaped, including a bottom edge, a first vertical edge and a second vertical edge connected to both ends of the bottom edge, and a hook groove is provided at one end of the first vertical edge. When the two adjusting rods are slidably inserted into each other, the hook groove is engaged with the second vertical edge.

[0015] Furthermore, the bottom edge, the first vertical edge, and the second vertical edge are integrally formed.

[0016] Therefore, by interlocking the groove with the second vertical side, the sliding connection of the two adjusting rods is ensured, and the overall strength of the one-piece molded adjusting rod is better, which also facilitates production.

[0017] Furthermore, the connecting device is an adjusting screw, with positive threads and negative threads respectively provided at both ends of the adjusting screw, and the two door frame hanging boxes are respectively screwed into the positive threads and negative threads of the adjusting screw.

[0018] Therefore, by adjusting the positive and negative threads at both ends of the screw, the relative proximity or distance between the two door frame hanging boxes can be achieved simply by turning the adjusting screw, thereby adjusting the relative distance between the two winding wheel devices to accommodate door leaves of different widths. This method is convenient to operate, has fewer parts, and saves costs.

[0019] Furthermore, the middle of the adjusting screw is machined into a polyhedron, which is located between the positive and negative threads.

[0020] Therefore, workers can use their hands or tools to hold the polyhedron and turn the adjusting screw, making the operation convenient.

[0021] Furthermore, the winding wheel device includes a base, an adjusting plate, and a winding wheel. The base is connected to the door frame hanging box, the adjusting plate is slidably connected to the base, and the winding wheel is rotatably mounted on the adjusting plate.

[0022] Therefore, the adjusting plate is slidably connected to the base, and the relative distance between the two winding wheels can be finely adjusted by adjusting the adjusting plate in order to tension the wire rope or belt rope wound on the two winding wheels.

[0023] Furthermore, a baffle is provided on the base, and a screw is screwed onto the adjusting plate. The screw abuts against the baffle to adjust the relative distance between the adjusting plate and the base.

[0024] Thus, the adjustment plate can be finely adjusted by sliding through the contact between the screw and the baffle.

[0025] A linkage door, including the linkage door suspension structure.

[0026] In summary, the linkage door hanging structure provided by the present invention has the following technical effects:

[0027] 1) The use of this linkage door hanging structure can simplify the installation process of the linkage door, facilitate the installation and fixing of steel wire rope or belt rope, speed up the installation, reduce the installation difficulty, and save labor costs;

[0028] 2) By interlocking the hook-shaped fasteners on the two adjusting rods, the two adjusting rods can be slidably connected to adjust the relative distance between the two winding wheel devices to adapt to door leaves of different widths, thereby reducing the types and quantities of accessories and saving costs;

[0029] 3) By adjusting the positive and negative threads on the screw to match the threaded holes on the two door frame hanging boxes, the relative distance between the two winding wheel devices can be adjusted to adapt to door leaves of different widths. Moreover, the operator can use their hand or tools to hold the polyhedron to turn the adjusting screw. The operation is convenient, with fewer parts, and saves costs.

[0030] 4) The adjusting plate is slidably connected to the base. The adjusting plate is adjusted by the contact between the screw and the baffle to achieve fine adjustment of the relative distance between the two winding wheels, so as to tighten the wire rope or belt rope wound on the two winding wheels.

Therefore, they should not be construed as limitations on this invention.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0046] Example 1

[0047] See Figure 1 and Figure 2 This invention discloses a linkage door hanging structure, including two sets of door frame hanging boxes 1, a connecting device, and two sets of winding wheel devices 3. The two sets of door frame hanging boxes 1 are used to install on the top of the door leaf; the connecting device connects the two door frame hanging boxes 1; the two winding wheel devices 3 are respectively disposed at the upper ends of the two door frame hanging boxes 1. The two sets of winding wheel devices 3 have the same structure and function, achieving the same technical effect; the only difference between them is their size, and the number and installation position of the pins 324 and the oblong holes 323. This invention also discloses a linkage door with the aforementioned linkage door hanging structure.

[0048] During the installation of interlocking doors, the relative distance between the two sets of winding wheel devices 3 at the top of the same door leaf will affect the movement stroke of the interlocking door. To align multiple interlocking doors when they retract, the movement stroke of the interlocking doors should be adapted to the width of the door leaf to ensure that the multiple interlocking doors slide and retract in alignment, achieving a space-saving and aesthetically pleasing effect. Therefore, it is necessary to determine the relative distance between the two sets of winding wheel devices 3 before winding steel wire rope or belt rope. In existing technology, the winding wheel device 3 is generally fixedly connected to the door frame mounting box 1. During installation, the door frame mounting box 1 is first screwed to the pulley in the upper guide rail, then the door leaf is installed onto the door frame mounting box 1, and finally, steel wire rope or belt rope is wound between the two winding wheel devices 3. However, in this installation process, the upper guide rail and the door leaf obstruct the installation space, making the installation of the steel wire rope or belt rope inconvenient, labor-intensive, and costly.

[0049] The linkage door hanging structure provided by this invention first fixes the two door frame hanging boxes 1 together through a connecting device to determine the relative distance between the two door frame hanging boxes 1. Then, a steel wire rope or belt rope is wound between two winding wheel devices 3. The linkage door hanging structure is then installed onto the pulleys in the upper guide rail, and finally the door leaf is installed. Using this linkage door hanging structure simplifies the installation process of the linkage door, facilitates the installation and fixing of the steel wire rope or belt rope, speeds up the installation, reduces installation difficulty, and saves labor costs.

[0050] See Figures 2 to 5In this embodiment, the connecting device includes two slidingly engaging adjusting rods 21, each of which is connected to a door frame hanging box 1 via a connector 4. Specifically, the cross-section of the adjusting rod 21 is approximately U-shaped, including a bottom edge 211, a first vertical edge 212 and a second vertical edge 213 connected to both ends of the bottom edge 211, the bottom edge 211, the first vertical edge 212 and the second vertical edge 213 forming the U-shape; a hook-shaped fastener 214 is provided on the bottom edge 211, and the two hook-shaped fasteners 214 engage when the two adjusting rods 21 are slidably engaged, thereby ensuring the sliding engagement of the two adjusting rods 21. To ensure the stability when the two adjusting rods 21 are engaged, the hook-shaped fastener 214 is located inside the U-shaped groove of the adjusting rod 21, and the first vertical edge 212 abuts against the bottom edge 211 when engaged. Therefore, by adjusting and fixing the relative distance between the two door frame hanging boxes 1 through the two sliding plug-in fastening adjustment rods 21, the relative distance between the two winding wheel devices is indirectly determined to adapt to door leaves of different widths, reducing the types and quantities of accessories and saving costs.

[0051] In this embodiment, the bottom edge 211, the first vertical edge 212, the second vertical edge 213, and the hook-shaped fastener 214 are integrally formed. The integrally formed adjusting rod 21 has better overall strength and is also easier to manufacture. Admittedly, the bottom edge 211, the first vertical edge 212, the second vertical edge 213, and the hook-shaped fastener 214 can also be welded together, and the present invention does not limit this.

[0052] In this embodiment, after the two adjusting rods 21 are slidably inserted and engaged and their relative distance is determined, the screw threaded through the first bottom edge 211 and abuts against the second bottom edge 211. The reaction force between the screw and the second bottom edge 211 is used to open the two adjusting rods 21 and achieve relative fixation.

[0053] In this embodiment, one end of the connector 4 is fixedly connected to the adjusting rod 21 by screws, and the other end of the connector 4 is fixedly connected to the door frame hanging box 1 by screws.

[0054] In other preferred embodiments, the connector 4 is integrally formed with the door frame hanging box 1, and the connector 4 is fixedly connected to the adjusting rod 21 by screws. The integrally formed connector 4 has better connection strength and higher accuracy in the connection position with the adjusting rod 21.

[0055] Specifically, the connector 4 is inserted into the U-shaped cavity of the adjusting rod 21, avoiding the hook-shaped fastener 214, and the screw passes through the connector 4 and is screwed to the bottom edge 211.

[0056] Admittedly, the present invention does not impose any limitations on the specific relative fixing method of the two adjusting rods 21 or the specific connection method between the connecting member 4 and the adjusting rods 21. As long as the relative fixing of the two adjusting rods 21 and the fixed connection between the connecting member 4 and the adjusting rods 21 can be achieved.

[0057] See Figure 5 and Figure 6 In this embodiment, the winding wheel device 3 includes a base 31, an adjusting plate 32, and a winding wheel 33. The base 31 is connected to the door frame hanging box 1, the adjusting plate 32 is slidably connected to the base 31, and the winding wheel 33 is rotatably mounted on the adjusting plate 32. A baffle 311 is provided on the base 31, and a screw 321 is screwed onto the adjusting plate 32. The screw 321 abuts against the baffle 311 to adjust the relative distance between the winding wheel 33 and the base 31.

[0058] Specifically, the upper surface of the base 31 is provided with two opposing flanges 312, and the adjusting plate 32 is clamped between the two flanges 312. The adjusting plate 32 has an oblong hole 323 along the length of the flanges 312, and a pin 324 passes through the oblong hole 323 to connect to the base 31, thereby achieving a sliding connection between the adjusting plate 32 and the base 31. Furthermore, the cooperation between the oblong hole 323 and the pin 324 limits the sliding distance of the adjusting plate 32. The rotating shaft 331 passes through the winding wheel 33 and the washer 332 in sequence and is connected to the adjusting plate 32; the baffle 311 is located at one end of the length direction of the baffle 312, and the adjusting plate 32 is provided with a screw seat 322 corresponding to the baffle 311. The screw 321 passes through the screw hole on the screw seat 322 and abuts against the baffle 311, thereby realizing the fine adjustment of the position of the winding wheel 33 so as to tension the wire rope or belt rope wound on the two winding wheels 33.

[0059] Example 2

[0060] See Figures 7 to 9 The technical feature that distinguishes this embodiment 2 from that of embodiment 1 is that the adjusting rod is different.

[0061] In this embodiment, the cross-section of the adjusting rod 21 is approximately H-shaped, including a bottom edge 211, a first vertical edge 212 and a second vertical edge 213 connecting the two ends of the bottom edge 211, and the bottom edge 211, the first vertical edge 212 and the second vertical edge 213 forming the H-shape; a hook groove 215 is provided on the first vertical edge 212, and when the two adjusting rods 21 are slidably inserted, the hook groove 215 engages with the second vertical edge 213. Thus, the engagement of the hook groove 215 with the second vertical edge 213 ensures the slidable insertion of the two adjusting rods 21.

[0062] See Figure 8 Specifically, the width of the first vertical side 212 is approximately twice the width of the second vertical side 213, and the thickness of the first vertical side 212 is approximately three times the thickness of the second vertical side 213; the first vertical side 212 is recessed inward on the side facing the second vertical side 213 to form the hook groove 215, and the hook groove 215 is approximately L-shaped and located above the bottom side 211; the height of the hook groove 215 matches the width of the second vertical side 213, and the depth of the hook groove 215 matches the thickness of the second vertical side 213.

[0063] See Figure 9 When the two adjusting rods 21 are slidably inserted, the second vertical side 213 engages within the hook groove 215, and the hook groove 215 abuts against the bottom edge 211, thereby achieving the slidable insertion of the two adjusting rods 21 and ensuring stability when the two adjusting rods 21 are inserted and engaged. Thus, by adjusting and fixing the relative distance between the two door frame hanging boxes 1 through the two slidably inserted adjusting rods 21, the relative distance between the two winding wheel devices is indirectly determined to accommodate door leaves of different widths, reducing the types and quantities of accessories and saving costs.

[0064] In this embodiment, after the two adjusting rods 21 are slidably inserted and engaged and their relative distance is determined, the screw threaded through the first bottom edge 211 and abuts against the second bottom edge 211. The reaction force between the screw and the second bottom edge 211 is used to open the two adjusting rods 21 and achieve relative fixation.

[0065] In this embodiment, the connection between the connector 4 and the adjusting rod 21 is as follows: the connector 4 is located above or below the bottom edge 211, and the screw passes through the connector 4 and is screwed to the bottom edge 211.

[0066] Admittedly, the present invention does not impose any limitations on the specific relative fixing method of the two adjusting rods 21 or the specific connection method between the connecting member 4 and the adjusting rods 21. As long as the relative fixing of the two adjusting rods 21 and the fixed connection between the connecting member 4 and the adjusting rods 21 can be achieved.

[0067] Example 3

[0068] See Figure 10 The only technical difference between this embodiment 3 and embodiment 1 is that the connecting device is different, and the connection method between the door frame hanging box 1 and the connecting device is different.

[0069] In this embodiment, the connecting device is an adjusting screw 22, and the door frame hanging box 1 is provided with a threaded hole 11 that mates with the adjusting screw 22. The relative distance between the two winding wheel devices 3 is adjusted by the engagement of the adjusting screw 22 with the threaded holes 11 on the two door frame hanging boxes 1, so as to adapt to door leaves of different widths. This method is convenient to operate, has fewer parts, and saves costs.

[0070] In this embodiment, in order to facilitate the adjustment of the relative proximity or distance between the two door frame hanging boxes 1, and to ensure that the two door frame hanging boxes 1 do not deflect at an angle during installation and use and remain relatively parallel, the two ends of the adjusting screw 22 are respectively provided with positive thread 221 and negative thread 222. The threaded holes 11 on the two door frame hanging boxes 1 respectively cooperate with the positive thread 221 and negative thread 222, that is, the threaded hole 11 on one door frame hanging box 1 is a positive thread hole, and the threaded hole 11 on the other door frame hanging box 1 is a negative thread hole.

[0071] In this embodiment, the middle of the adjusting screw 22 is machined into a polyhedron 223, which is located between the positive thread 221 and the negative thread 222. Therefore, the operator can use their hand or a tool to hold the polyhedron 223 to turn the adjusting screw 22, facilitating operation.

[0072] In this embodiment, the polyhedron 223 is a hexahedron. Of course, the polyhedron 223 can also be a trihedron, tetrahedron, pentahedron, octahedron, etc., so that the staff can hold the polyhedron 223 by hand or with tools.

[0073] In summary, the linkage door hanging structure provided by this invention simplifies the installation process of linkage doors, facilitates the installation and fixing of steel wire ropes or belt ropes, speeds up installation, reduces installation difficulty, and saves labor costs. The hook-shaped fasteners 214 on the two adjusting rods 21 interlock to achieve sliding connection of the two adjusting rods 21, allowing adjustment of the relative distance between the two winding wheel devices 3 to adapt to door leaves of different widths, reducing the types and quantities of accessories, and saving costs. The positive and negative threads 221 and 222 on the adjusting screw 22 connect with the two... The threaded holes 11 on the door frame hanging box 1 are matched to adjust the relative distance between the two winding wheel devices 3 to adapt to door leaves of different widths. The operator can use the polyhedron 223 to turn the adjusting screw 22 by hand or tool. The operation is convenient, with few parts and cost-saving. The adjusting plate 32 is slidably connected to the base 31. The adjusting plate 32 is adjusted by the abutment of the screw 321 and the baffle 311 to achieve fine adjustment of the relative distance between the two winding wheels 33, so as to tighten the steel wire rope or belt rope wound on the two winding wheels 33.

[0074] The technical means disclosed in this invention are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications are also considered within the scope of protection of this invention.
