The conveyor belt 22 is preferably a rack; and the conveyor belt 22 forms an upper conveyor belt section 221 on the upper side and a lower conveyor belt section 222 on the lower side correspondingly on the upper and lower sides of the transmission wheel 21. The driving member 23 is fixedly installed at one end of the track beam 10, used to drive the transmission wheel 21 to rotate, and is connected to one of the transmission wheels 21 to drive the transmission wheel 21 to rotate forward or reverse, thereby driving the transmission belt 22 to rotate forward or reverse; in the utility model, the driving member 23 uses a motor that can rotate forward and reverse, and drives the transmission wheel 21 to rotate through the motor. The control board unit 24 is fixedly installed in the track beam 10 and adjacent to the driving member 23. The driving member 23 is electrically connected to the control board unit 24 to control the forward and reverse rotation and start and stop of the driving member 23. It can be understood that the control board unit 24 is externally connected to a power source and is provided with a power control switch.

[0025] Furthermore, in order to achieve adjustable tension of the conveyor belt 22 mounted on the two conveyor wheels 21, the hanging rail structure 100 includes a conveyor belt tensioning adjustment structure 25 arranged at one end of the track beam 10, and the conveyor wheel 21 at one end of the conveyor belt 22 is arranged on the conveyor belt tensioning adjustment structure 25. By adjusting the conveyor belt tensioning adjustment structure 25, the distance between the conveyor wheel 21 arranged on the conveyor belt tensioning adjustment structure 25 and the other conveyor wheel 21 can be adjusted, thereby adjusting the tension of the conveyor belt 22.

[0026] See also Figure 5The conveyor belt tensioning adjustment structure 25 includes a fixed base 251, a sliding plate base 252, an adjustment base plate 253, a threaded adjustment rod 254, a stud sleeve 255 and a plurality of locking bolts 256. The fixed base 251 is fixed to one end of the track beam 10 by the locking bolts 256. The fixed base 251 has a bottom plate 2511 and a top plate 2512. The bottom plate of the fixed base 251 is locked to the connecting wall 13 of the track beam 10 by the locking bolts 256, and a fixing hole is opened on the top plate 2512. The sliding plate seat 252 is slidably mounted on the top plate 2512 of the fixed base 251. The sliding plate seat 252 includes a sliding plate portion 2521 and a folding plate portion 2522 at one end of the sliding plate portion 2521 which is bent integrally. The sliding plate portion 2521 is provided with an axle body for the transmission wheel 21 to be sleeved on the axle body. The sliding plate portion 2521 is provided with a strip hole for matching with the fixing hole on the top plate for the locking bolt 256 to penetrate and lock the sliding plate portion 2521 on the fixed base 251. The folding plate portion 2522 is provided with a through hole for matching with the fixing hole on the top plate. The threaded adjustment rod 254 cooperates; the adjustment base plate 253 is fixedly arranged in the track beam 10 and has a certain distance from the fixed base 251. A screw hole is opened on the adjustment base plate 253, and the outer periphery of the rod body of the threaded adjustment rod 254 has a thread. The threaded adjustment rod 254 is threadedly matched with the screw hole of the adjustment base plate 253, and passes through the screw hole of the adjustment base plate 253 and extends into the through hole on the folding plate part 2522. The stud sleeve 255 has an internal thread, which is sleeved on the rod body of the threaded adjustment rod 254 and is located between the folding plate part 2522 and the adjustment base plate 253. When the tension of the conveyor belt 22 is adjusted, the locking bolts 256 on the strip hole and the fixing hole are loosened, that is, the fixed connection between the sliding plate seat 252 and the fixing base 251 is loosened, so that the sliding plate seat 252 can slide relative to the fixing base 251, and then the stud sleeve 255 on the threaded adjustment rod 254 is rotated so that the end of the stud sleeve 255 abuts against the folded plate portion 2522 of the sliding plate seat 252, thereby pushing the sliding plate seat 252 to slide on the fixing base 251, thereby driving the transmission wheel 21 on the sliding plate seat 252 to change the distance relative to the other transmission wheel 21, and the strip hole also has a corresponding displacement change relative to the fixing hole (ensuring that the hole length of the strip hole after the displacement change is sufficient to cover the fixing hole). When the conveyor belt 22 is adjusted to a suitable tension, the sliding plate seat 252 is fixed to the fixing base 251 by loosening the locking bolts 256 on the strip hole and the fixing hole, thereby fixing the distance between the two transmission wheels 21 after adjustment.

[0027] Furthermore, in order to facilitate pushing the sliding plate seat 252 to slide relative to the fixed base 251 after loosening, a handle 2523 is formed on the top side of the folding plate portion 2522, so that after holding the handle 2523 to push the sliding plate seat 252 to slide, the stud sleeve 255 is rotated to press the stud sleeve 255 tightly against the folding plate portion 2522.

[0028] The two pulley assemblies 30 are relatively installed at the two ends of the lower track area of ​​the track beam 10, and one of the pulley assemblies 30 is connected to the upper conveyor belt section 221 of the conveyor belt 22, and the other pulley assembly 30 is connected to the lower conveyor belt section 222 of the conveyor belt 22, and the connection positions of the two pulley assemblies 30 and the conveyor belt 22 are symmetrical about the center position of the conveyor belt 22. In this way, when the conveyor belt 22 rotates, it can drive the two pulley assemblies 30 to move towards each other or move away from each other at the same time. When moving towards each other, they will abut against each other at the center position of the conveyor belt 22. When moving away from each other in the opposite direction, they will arrive at the two ends of the track beam 10 at the same time, and the distance from the center position of the conveyor belt 22 is the same.

[0029] See also Figure 6 Each pulley assembly 30 includes a main pulley unit 31, a slave pulley unit 32 and a hanging plate 33. The main pulley unit 31 includes a first pulley body 311, a first fixed structure 312 connected to the first pulley body 311 and extending downward, and a clamping structure 313 installed on the first pulley body 311 and extending upward. The first pulley body 311 is slidably installed on the lower wall 12 of the lower track area. The first pulley body 311 includes a shell and a plurality of pulleys installed in the shell. The plurality of pulleys can be arranged in two groups, front and rear, and each group can be two sets arranged side by side. Further, by arranging guide ribs along the extension direction on the lower wall 12, each group of pulleys is clamped on both sides of the guide ribs, and the first pulley body 311 can be guided to slide along the extension direction of the lower wall 12.

[0030] The first fixing structure 312 is formed below the lower wall 12 and is used to fix the hanging plate 33. The first fixing structure 312 can be an L-shaped plate, one end of which is fixed to the first pulley body 311, and the other end bypasses the outside of the lower wall 12 and extends below the lower wall 12. It can be understood that the first fixing structure 312 can also be a downward extension plate integrally formed on the first pulley body 311, bypassing the outside of the lower wall 12 and bending below the lower wall 12.

[0031] The fixing structure 313 is fixedly connected to the first pulley body 311, and one end of the fixing structure 313 extends upward over the dividing strip 14 and extends into the upper track area, and is used to be fixedly connected to the upper conveyor belt segment 221 or the lower conveyor belt segment 222 of the conveyor belt 22, so that when the conveyor belt 22 moves, the main pulley unit 31 is driven to slide along the extension direction of the lower wall 12. In this embodiment, the fixing structure 313 includes a connecting plate and a fixing member, one end of the connecting plate is fixedly connected to the first pulley body 311, and the other end extends into the upper conveyor belt segment 221 or the lower conveyor belt segment 222 of the conveyor belt 22, and the fixing member has a fixing groove, and the fixing member is fixedly connected to the other end of the connecting plate by bolts, and the fixing groove of the fixing member is fastened to the upper conveyor belt segment 221 or the lower conveyor belt segment 222 of the conveyor belt 22.

[0032] The structure of the slave pulley unit 32 is basically the same as that of the master pulley unit 31, and the only difference is that the slave pulley unit 32 does not have the fixing structure 313 described in the master pulley unit 31, and the slave pulley unit 32 may not be connected to the conveyor belt 22. The slave pulley unit 32 mainly cooperates with the master pulley unit 31 to carry larger objects and improve the stability of operation. Similarly, the slave pulley unit 32 includes a second pulley body 321 and a second fixed structure 322 connected to the second pulley body 321, the second pulley body 321 is slidably mounted on the lower wall 12, and the second fixed structure 322 of the slave pulley unit 32 bypasses the outer side of the lower wall 12 and is located below the lower wall 12.

[0033] The two ends of the hanging plate 33 are respectively fixed to the first fixing structures 312 of the main pulley unit 31 and the slave pulley unit 32, so that when the main pulley unit 31 moves, the hanging plate 33 and the slave pulley unit 32 are driven to move together, and the hanging plate 33 is used to connect the door body or the cabinet body, so that the door body or the cabinet body is driven to move together through the hanging plate 33. In this embodiment, the hanger plate 33 includes a hanger plate body 331 and vertical plate portions 332 fixedly connected to the two ends of the top surface of the hanger plate body 331. The hanger plate body 331 is a long strip-shaped plate body, and the vertical plate portion 332 is roughly an "I"-shaped plate, which is erected on the top surface of the hanger plate body 331. The bottom of the vertical plate portion 332 is fixedly connected to the top surface of the hanger plate body 331, and the top of the vertical plate portion 332 is fixedly connected to the first fixed structure 312 of the main pulley unit 31 and the second fixed structure 322 of the slave pulley unit 32, specifically, it is fixedly connected to the plate portions of the first fixed structure 312 and the second fixed structure 322 located below the lower wall 12, and the fixing method is, for example, screw connection.

[0034] Furthermore, the hanging rail structure 100 includes a limit member 40, which is installed at one end or the middle position of the lower wall 12 of the track beam 10, and is used to block the pulley assembly 30 when it slides to the extreme position, thereby limiting the transmission stroke of the conveyor belt assembly 20. It can be understood that since the two pulley assemblies 30 are connected to the conveyor belt 22 and are linked, it is only necessary to limit the position of one of the pulley assemblies 30, and the position of the other pulley assembly 30 is also limited accordingly. By providing a limit member 40 at one end of the track beam 10, the farthest relative position of the two pulley assemblies 30 can be limited, that is, the maximum expansion position when the double door body is opened is limited. Please refer to Figure 7In this embodiment, the limit member 40 adopts a threaded tension structure, including a jacket 41, a sleeve core block, a clamping plate 42 and an adjusting bolt 43. The jacket 41 is a U-shaped jacket, including a transverse plate portion and a longitudinal plate portion vertically connected to both ends of the transverse plate portion. A movable guide hole 411 is opened on the transverse plate portion, and an L-shaped notch 412 is formed at a corner of the longitudinal plate portion away from the transverse plate portion. The sleeve core block is fixedly accommodated in the jacket 41, and a stud hole is formed on the sleeve core block. The clamping piece 42 is L-shaped, and has a clamping piece portion 421 and a guide piece portion 422 which is integrally and vertically formed at one end of the clamping piece portion 421. The clamping piece portion 421 is provided with a matching hole, and a protruding tip is formed at the end of the guide piece portion 422. The clamping piece 42 is installed in the sleeve 41 and fits against the outer side of the sleeve core block. The clamping piece portion 421 and the L-shaped notch 412 of the sleeve 41 form a clamping opening for clamping to the lower wall 12. The tip of the guide piece portion 422 extends into the movable guide hole 411 to guide the clamping piece 42 to slide up and down along the sleeve core block; the adjusting bolt 43 passes through the matching hole of the clamping piece 42 and is threadedly engaged with the stud hole on the sleeve core block. When the limit member 40 is installed on the lower wall 12, a clamping opening is formed at the clamping piece 421 and the L-shaped notch 412 of the longitudinal plate portion of the sleeve 41 to clamp it on the lower wall 12. The limit member 40 can be stably locked on the lower wall 12 by passing the adjusting bolt 43 through the matching hole of the clamping piece 42 and the stud hole on the sleeve core block for threaded locking. When the position of the limit member 40 on the lower wall 12 needs to be adjusted, the lock can be released by loosening the adjusting bolt 43. The limit member 40 can slide along the lower wall 12, and after sliding to the preset position, it can be locked by adjusting the bolt 43.

[0035] Furthermore, the limit member 40 includes a buffer gasket 44, which is installed on the side of the jacket 41 facing the corresponding pulley assembly 30, so as to provide buffering when the pulley assembly 30 slides onto the limit member 40 to avoid severe impact and thus become undurable.

[0036] Furthermore, the limiting member 40 is also provided in the middle of the lower wall 12 of the track beam 10, so that when the two pulley assemblies 30 are brought close to each other and connected, they can both abut against the two sides of the limiting member 40, thereby performing sliding limiting at the middle docking position and also buffering the two pulley assemblies 30.

[0037] When the hanging rail structure 100 provided by the utility model is applied to the door body, since the hanging rail structure 100 has a better load-bearing capacity, the weight of the door body can be completely suspended on the lower wall 12, and the traditional lower slide rail for supporting the weight of the door body can be omitted. For example, the utility model provides a double-door furniture, including a door frame, a guide rail structure installed on the door frame, and two door bodies, the hanging rail structure is installed on the top side of the door frame, and the top sides of the two door bodies are respectively fixed to the hanging plates 33 of the two pulley assemblies 30.

[0038] The hanging rail structure 100 provided by the present invention can be applied not only to double-opening doors or double-opening windows, but also to double-opening furniture, such as cabinets. Since the hanging rail structure 100 has better load-bearing capacity, it can even suspend heavier cabinets for sliding, so a new double-opening hidden multifunctional cabinet can be designed.

[0039] See also Figure 8 A hidden multifunctional cabinet 200 includes a frame 51, the hanging rail structure 100, a door panel set 52 and two sliding cabinets 53. The frame 51 is divided into a main cabinet frame 512 and a top cabinet frame 513 formed on the top of the main cabinet frame 512 by a partition 511. The hanging rail structure 100 is installed in the top cabinet frame 513. The partition 511 is provided with a penetrating sliding groove extending along the length direction for the vertical plate portion 332 of the hanging plate 33 to pass through. The door panel set 52 is vertically arranged at the front side of the middle part of the main cabinet frame 512, so that a hollow chamber is formed in the main cabinet frame 512 behind the door panel set 52, which can be regarded as a door sealing area; the two sides of the door panel 53 in the main cabinet frame 512 can be regarded as a sliding cabinet accommodating area, and two sliding cabinets 53 are respectively installed in the sliding cabinet accommodating area. The two sliding cabinets 53 are respectively connected to the two pulley assemblies 30 of the hanging rail structure 100, so that the two sliding cabinets 53 slide towards or in the opposite direction in the main cabinet frame 512 under the drive of the hanging rail structure 100. When the two sliding cabinets 53 slide to docking, the two sliding cabinets 53 are covered by the door panel set 52 and hidden behind the door panel set 52. When sliding in the opposite direction to the farthest distance, they completely enter the sliding cabinet accommodating area on both sides of the door panel set 52, and each sliding cabinet 53 can be fully displayed.

[0040] Furthermore, functional components are arranged on the cabinet wall on the front side of each sliding cabinet storage area in the main cabinet frame 512, such as installing the fitness equipment structure described in CN202321571497.3, or the layout of the mirror, projection screen, etc. can be arranged on the cabinet wall on the front side of the cabinet to realize the functional structure, and will not interfere with the sliding of the sliding cabinet 53, so that it can be used as a functional area other than display. When the sliding cabinet 53 is slid and stored in the door sealing area, the functional components of the sliding cabinet storage area are presented, and the user can use the corresponding functional components. When the sliding cabinet 53 slides to the sliding cabinet storage area, the functional components are hidden to display the objects placed in the sliding cabinet 53. It can be understood that the sliding cabinet 53 can be provided with a layer cabinet with multiple layers of shelves, and each layer is for placing objects.

[0041] Furthermore, the door panel set 52 may be configured as two main door panels 521 arranged side by side, and the width of each main door panel 521 corresponds to the width of the sliding cabinet 53, so that the sliding cabinet 53 can be hidden. Furthermore, each main door panel 521 may be provided with a hinged door 5211, and the hinged door 5211 may rotate relative to the main door panel 521, so that when the sliding cabinet 53 stored behind the door panel set 52 needs to be used, it can also be presented by opening the hinged door 5211 for use.

[0042] In summary, the utility model provides a conveyor belt tensioning adjustment structure, which is achieved by setting a fixed base 251 in the track beam 10, setting a slidable sliding plate seat 252 on the surface of the fixed base 251, and setting an axle body on the sliding plate seat 252 for a conveying wheel 21 to be sleeved, and the shaft sleeve column of the other conveying wheel 21 is fixedly installed in the track beam 10. In this way, the distance between the two conveying wheels 21 can be adjusted by sliding the sliding plate seat 252 relative to the fixed base 251, thereby adjusting the tension of the conveyor belt 22. By unlocking the locking bolt 256, the sliding plate seat 252 can slide relative to the fixed base 251. After the sliding plate seat 252 is adjusted to the right position, that is, after the tension is adjusted appropriately, one end of the stud sleeve 255 is required to immediately abut the sliding plate seat 252, otherwise the sliding plate seat 252 is easy to move under the traction of the conveyor belt 22.
