Description

Technical Field

[0001] The utility model relates to the technical field of phantom doors, in particular to a guiding mechanism and a phantom door system. Background Art

[0002] In modern home and commercial space design, the phantom door, also known as a hidden-rail sliding door or a barn door, is favored for its unique hidden-rail design and simple visual effect. However, during the actual installation and use process, the stability problem of the phantom door has gradually become the focus of the industry. Especially during the installation process, if the workers fail to follow strict operating specifications or choose non-standard materials, potential hazards may be left for subsequent use.

[0003] Specifically, the stability problem of the phantom door is mainly reflected in the upward lifting phenomenon caused by uneven force during the movement of the door body. This phenomenon often stems from the insecure installation of the pulleys and the unreasonable setting of the gap between the door panel and the wall. When the pulleys cannot be effectively fixed on the preset track or the gap between the door panel and the wall is too large, the door body is prone to being interfered by external factors during the sliding process, such as wind force and uneven pushing and pulling force by people, resulting in the upward lifting of the door body and affecting the use effect and safety.

[0004] In addition, the long-term use and frequent opening and closing of the phantom door will also have an adverse impact on its stability. Over time, the wear of the pulleys and the track increases, and the load-bearing capacity of the door body gradually weakens, further increasing the risk of the door body lifting upward. Especially when the door body is subjected to a large impact force or accidentally damaged during use, its stability problem becomes more prominent. Summary of the Utility Model

[0005] In order to overcome at least one of the above-mentioned defects of the prior art, the utility model provides a guiding mechanism and a phantom door system. It can solve the problem of the upward lifting of the door body, thereby improving the sliding stability of the door body and further enhancing the service life.

[0006] The technical solution adopted by the utility model to solve its problems is as follows:

[0007] A guiding mechanism includes: a track profile, on which a sliding track is provided, and at least one side of the sliding track is provided with a clamping groove; a pulley assembly for being assembled to the bottom of the door body, the pulley assembly including a pulley frame and a roller, the roller being rotatably connected within the pulley frame, and the pulley assembly sliding on the sliding track; a longitudinal limiting member assembled within the pulley frame, and a part of the longitudinal limiting member extends out of the pulley frame and is clamped with the clamping groove, so that when the pulley assembly slides along the sliding track, the rolling surface of the roller always fits or is close to the sliding track.

[0008] By adopting the above solution, a sliding rail and a pulley assembly are provided to ensure that the door body can move smoothly along the rail when sliding. In particular, the design of the longitudinal limiter, which is assembled in the pulley frame and extends from the pulley frame to engage with the clamping groove on the rail, enables the rolling surface of the roller to always fit or be close to the sliding rail when the pulley assembly slides along the sliding rail, reducing the lifting phenomenon caused by uneven force or external factors; not only does it enhance the stability of the connection between the pulley assembly and the rail, but it also makes the installation process more standardized, reducing stability problems caused by improper installation.

[0009] Furthermore, a retaining groove is provided on one side of the sliding rail, and a horizontal limit piece is provided on one end of the pulley assembly. The horizontal limit piece at least partially extends in the direction of the track profile and abuts against the other side of the sliding rail, so that when the pulley assembly slides along the sliding rail, the pulley assembly is restricted from moving away from the retaining groove in the horizontal direction of the horizontal limit piece.

[0010] By adopting the above solution, the stability of the pulley assembly in the horizontal direction is ensured, and lateral displacement or shaking caused by external force is prevented. The horizontal limiter combines with the longitudinal limiter to form a common limiting effect in two directions, forming a stable support system, so that the movement of the pulley assembly on the sliding rail is smoother and more reliable.

[0011] Furthermore, the horizontal limit member includes: a first assembly body, the first assembly body having a first rotation space; a rotating body, the surface of the rotating body is provided with an outwardly protruding abutment structure, the abutment structure is used to abut with the other side of the sliding rail, the rotating body is located in the first rotation space, and both ends are rotatably connected to the first assembly body, and one end of the rotating body is provided with an operating part, and the operating part controls the rotation of the rotating body to change the abutment state of the abutment structure.

[0012] By adopting the above scheme, the rotating body changes the abutment state of the abutment structure by rotating, thereby realizing the horizontal limitation of the pulley assembly. Before installation, the rotating body is rotated to a non-abutment state to facilitate installation from one side of the sliding rail. When the rolling surface of the roller is in contact with or close to the sliding rail, the rotating body is rotated to an abutment state to maintain a stable sliding state.

[0013] Furthermore, the height of the abutment structure protruding from the surface of the rotating body is greater than the distance from the rotating body to the sliding rail.

[0014] By adopting the above solution, since the height of the abutting structure protruding from the surface of the rotating body is relatively large, when the rotating body is adjusted to the position abutting against the sliding rail, the abutting structure can fully contact and press the other side of the sliding rail. This close contact not only restricts the movement of the pulley assembly in the horizontal direction but also provides sufficient friction to prevent the door body from sliding or shaking when subjected to an external force.

[0015] Further, the longitudinal limiting member includes: a second assembly body assembled in the pulley bracket; a limiting body fixedly connected to the second assembly body, with an avoidance groove provided in the direction of the sliding rail on the limiting body, the two sides of the avoidance groove are respectively arranged at intervals with the two sides of the sliding rail, and a clamping strip is further arranged on one side of the avoidance groove, and the clamping strip is clamped with the clamping groove.

[0016] By adopting the above solution, the design of the avoidance groove allows part of the structure of the pulley assembly to enter the groove during the sliding process, thereby reducing the direct contact area with the sliding rail, reducing friction and wear. At the same time, the avoidance groove also provides a certain space, enabling the pulley assembly to have a certain buffering and adaptability when subjected to an external force. The design of the clamping strip enables the limiting body to be firmly fixed on the sliding rail, preventing the pulley assembly from longitudinally shifting or falling off during the sliding process. At the same time, the clamping connection method between the clamping strip and the clamping groove also provides a convenient installation and disassembly method, improving work efficiency.

[0017] Further, the pulley assembly further includes a height adjustment device, which includes: an outer housing having a first accommodation cavity; an inner frame movably assembled in the first accommodation cavity, the inner frame having a second accommodation cavity, and the pulley bracket is assembled in the second accommodation cavity; an adjustment member provided at one end of the inner frame; wherein, an inclined waist-shaped hole is provided on the inner frame, and a sliding rod is provided on the outer housing, and the sliding rod slides in the waist-shaped hole, and the adjustment member is used to drive the inner frame so that the sliding rod displaces along the waist-shaped hole.

[0018] By adopting the above solution, when it is necessary to adjust the height of the pulley assembly, the user or installer drives the inner frame to move by operating the adjustment member. The inclined waist-shaped hole on the inner frame allows the sliding rod to slide inside it. As the inner frame moves, the sliding rod also displaces along the path of the waist-shaped hole. This displacement causes the position of the pulley assembly relative to the outer housing to change, thereby realizing the height adjustment; the height adjustment device allows the user to adjust the height of the pulley assembly according to actual needs to adapt to different installation environments or meet specific usage requirements.

[0019] Further, the adjusting member includes: a limiting block which is limited within the inner frame; an adjusting screw, the head of the adjusting screw is located outside one end of the outer housing, and the tail of the adjusting screw sequentially passes through one end of the outer housing and one end of the inner frame and is screwed to the limiting block.

[0020] By adopting the above solution, precise adjustment of the height of the pulley assembly can be achieved by rotating the adjusting screw to meet different installation and usage requirements; the screwed structure of the limiting block and the adjusting screw ensures the stability and reliability during the adjustment process, preventing adjustment failure caused by uneven force or loosening; the head design of the adjusting screw facilitates operation by users or installers, improving the convenience and efficiency of adjustment.

[0021] Further, a brush is provided on the inner frame or the pulley frame.

[0022] By adopting the above solution, dust and debris on the surface of the sliding rail can be cleaned, the friction coefficient between the pulley assembly and the sliding rail can be reduced, making the pulley assembly slide more smoothly, reducing noise and vibration; it can also act as an oiling brush after applying lubricant, forming a protective film between the pulley assembly and the sliding rail to prevent direct contact and wear between metals.

[0023] A phantom door system includes a door body, a door body frame, an upper guide wheel and a guiding mechanism. The track profile is arranged below the door body and the door body frame. The upper guide wheel is assembled on the door body frame and is used to provide the guiding force for the upper part when the door body is opened and closed. The pulley assembly is fixed to the bottom of the door body to provide the force for the lower part of the door body to slide along the sliding rail.

[0024] By adopting the above solution, smooth, quiet opening and closing of the door body are achieved, and at the same time, the problem of the door body being lifted by external forces will not occur during the operation process.

[0025] Further, the periphery of the door body further includes an upper frame, side frames and a lower frame. The bottom of the lower frame has a concave assembly groove. The pulley assembly is assembled in the assembly groove, and a horizontal limiting member is assembled on one side of the pulley assembly close to the end of the assembly groove.

[0026] By adopting the above solution, the concave assembly groove can stably install and accommodate the pulley assembly and the horizontal limiting member, improving the stability during the sliding process.

[0027] In summary, a guiding mechanism and a phantom door system provided by the present utility model have the following technical effects:

[0028] 1. By designing the sliding rail and pulley assembly, and combining the clamping mechanism of the longitudinal limiting part and the clamping groove, it is ensured that the pulley assembly can always be closely attached to or close to the sliding rail during the sliding process, effectively preventing the phenomenon of the door body lifting caused by uneven force or external factors such as wind force and uneven manual pushing and pulling force, thus significantly improving the sliding stability of the door body;

[0029] 2. The design of the longitudinal limiting part makes the connection between the pulley assembly and the track more stable, reducing the problems of unsmooth sliding or potential safety hazards caused by pulley loosening or deviation. This stable connection method not only extends the service life of the phantom door system but also improves the overall safety performance;

[0030] 3. The design of the guiding mechanism makes the installation process more standardized and normalized. Workers only need to install according to the established steps and requirements to ensure the correct connection and stability between the pulley assembly and the track, thus reducing the stability problems caused by improper installation;

[0031] 4. Since the guiding mechanism effectively solves the problem of the door body lifting and enhances the connection stability between the pulley assembly and the track, it can reduce the wear and damage caused by frequent opening and closing and long-term use, thus extending the overall service life of the phantom door system.

[0042] For better understanding and implementation, the technical solutions in the embodiments of the present utility model will be clearly and completely described and discussed below in conjunction with the drawings of the present utility model. Obviously, what is described here is only a part of the examples of the present utility model, not all of the examples. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present utility model.

[0043] For the convenience of understanding the embodiments of the present utility model, the following will further explain with specific examples in conjunction with the drawings, and each embodiment does not constitute a limitation on the embodiments of the present utility model.

[0044] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present utility model.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this utility model belongs. The terms used in the description of this utility model herein are only for the purpose of describing specific embodiments and are not intended to limit this utility model.

[0046] Referring to Embodiment 1 of this utility model Figures 1-9 As shown, a guiding mechanism is disclosed, which is applied to the bottom of a door body 6. Specifically, it refers to the bottom of the door body 6 of a phantom door in this Embodiment 1. In other embodiments, it can also be applied to the bottom of other door and window structures, and no specific limitation is made here; the guiding mechanism includes a track profile 1, a pulley assembly 2 and a longitudinal limiting member 3. A sliding track 11 is provided on the track profile 1. At least one side of the sliding track 11 is provided with a clamping groove 111. The pulley assembly 2 is used to be assembled to the bottom of the door body 6. The pulley assembly 2 includes a pulley frame 21 and a roller 22. The roller 22 is rotatably connected inside the pulley frame 21. The pulley assembly 2 slides on the sliding track 11. The longitudinal limiting member 3 is assembled inside the pulley frame 21, and a part of the longitudinal limiting member 3 extends out of the pulley frame 21 and is clamped with the clamping groove 111, so that when the pulley assembly 2 slides along the sliding track 11, the rolling surface 221 of the roller 22 is always in contact with or close to the sliding track 11. By providing the sliding track 11 and the pulley assembly 2, it is ensured that the door body can move smoothly along the track during sliding. Especially the design of the longitudinal limiting member 3, which is assembled inside the pulley frame 21 and extends out of the pulley frame 21 to be clamped with the clamping groove 111 on the track, makes the rolling surface 221 of the roller 22 always in contact with or close to the sliding track 11 when the pulley assembly 2 slides along the sliding track 11, reducing the lifting phenomenon caused by uneven force or external factors; not only enhancing the connection stability between the pulley assembly 2 and the track, but also making the installation process more standardized and reducing the stability problems caused by improper installation.

[0047] During installation, when clamping grooves 111 are provided on both sides of the sliding track 11, the pulley assembly 2 needs to be inserted into the sliding track 11 from one end before the track profile 1 is assembled. Then, the track profile 1 is fixed above the bottom of the ground or the door body frame 7. Finally, the pulley assembly 2 is connected to the bottom of the door body 6. At this time, the door body 6 can slide along the sliding track 11 to achieve the effect of opening and closing the door. When the clamping groove 111 is provided on only one side of the sliding track 11, the pulley assembly 2 can be horizontally pushed onto the sliding track 11 on the side of the clamping groove 111 of the sliding track 11. Therefore, there is no need to limit the installation sequence of the track profile 1 and the pulley assembly 2. After all the installations, the door body 6 can slide along the sliding track 11 to achieve the effect of opening and closing the door. In this Embodiment 1, the clamping groove 111 is provided on only one side of the sliding track 11.

[0048] When the sliding rail 11 is only provided with a locking groove 111 on one side, in order to prevent it from derailing in the installation direction after installation, in some embodiments, a horizontal limit member 4 is provided at one end of the pulley assembly 2, and the horizontal limit member 4 at least partially extends in the direction of the track profile 1 and abuts against the other side of the sliding rail 11, so that when the pulley assembly 2 slides along the sliding rail 11, the pulley assembly 2 is restricted from moving away from the locking groove 11 in the horizontal direction of the horizontal limit member 4, thereby ensuring the stability of the pulley assembly 2 in the horizontal direction and preventing lateral displacement or shaking caused by external force. The horizontal limit member 4 combines with the longitudinal limit member 3 to form a common limiting effect in two directions, forming a stable support system, so that the movement of the pulley assembly 2 on the sliding rail 11 is more stable and reliable. Specifically, in the present embodiment 1, the horizontal limit member 4 includes a first assembly body 41 and a rotating body 42, the first assembly body 41 has a first rotation space 411, preferably, the first assembly body 41 is formed by bending a sheet metal material in one piece, and the specific bending method is to bend both ends of the sheet metal material to the same side to form the first rotation space 411, the bent portion is provided with a hole, the rotating body 42 has an axial hole 422, and the rotating body 42 is rotated and assembled into the first rotation space 411 by passing the rotating rod 44 through the hole of the bent portion and the axial hole 422, and the rotating body 42 is rotated and assembled into the first rotation space 411, and the surface of the rotating body 42 is provided with an outwardly convex abutment structure 421, and the abutment structure 421 is used to abut against the other side of the slide rail 11 Side abutment, both ends of the rotating body 42 are rotatably connected to the first assembly body 41, one end of the rotating body 42 is provided with an operating part 43, the operating part 43 is the end of the rotating rod 44, the operating part 43 controls the rotation of the rotating body 42 to change the abutment state of the abutment structure 421; the rotating body 42 changes the abutment state of the abutment structure 421 by rotation, thereby realizing the horizontal limitation of the pulley assembly 2. Before installation, the rotating body 42 is rotated to a non-abutment state to facilitate installation from one side of the sliding rail 11. When the rolling surface 221 of the roller 22 is in contact with or close to the sliding rail 11, the rotating body 42 is rotated to an abutment state to maintain a stable sliding state.

[0049] It should be noted that the height of the abutment structure 421 protruding from the surface of the rotating body 42 is greater than the distance from the rotating body 42 to the slide rail 11. The reason for this arrangement is that by increasing the height of the abutment structure 421 protruding from the surface of the rotating body 42, when the rotating body 42 is adjusted to abut against the slide rail 11, the abutment structure 421 can fully contact and press the other side of the slide rail 11. This close contact not only limits the horizontal movement of the pulley assembly 2, but also provides sufficient friction to prevent the door body from sliding or shaking when subjected to external force.

[0050] In a specific embodiment, to better achieve longitudinal limitation with the clamping groove 111, the structure of the longitudinal limiting member 3 is further refined. The longitudinal limiting member 3 includes a second assembly body 31 and a limiting body 32. The second assembly body 31 is assembled in the pulley bracket 21, and the limiting body 32 is fixedly connected to the second assembly body 31. Preferably, the second assembly body 31 and the limiting body 32 are integrally formed. The limiting body 32 is provided with an avoidance groove 321 towards the sliding rail 11. The two sides of the avoidance groove 321 are respectively arranged at intervals with the two sides of the sliding rail 11. A clamping strip 322 is further arranged on one side of the avoidance groove 321. The clamping strip 322 is clamped with the clamping groove 111. The design of the avoidance groove 321 allows part of the structure of the pulley assembly 2 to enter the groove during the sliding process, thereby reducing the direct contact area with the sliding rail 11, and reducing friction and wear. At the same time, the avoidance groove 321 also provides a certain space, enabling the pulley assembly 2 to have a certain buffering and adaptation ability when subjected to an external force. The design of the clamping strip 322 enables the limiting body 32 to be firmly fixed on the sliding rail 11, preventing the pulley assembly 2 from longitudinally shifting or falling off during the sliding process. At the same time, the clamping method of the clamping strip 322 and the clamping groove 111 also provides a convenient installation and disassembly method, improving work efficiency.

[0051] During the actual installation process, due to the different heights of the actual door frames, it is necessary to precisely adjust the dimensions of the door body 6 itself when installing the door body 6 to improve the aesthetics after installation and at the same time avoid causing trouble to the installation. However, usually, the above effects cannot be well achieved, and the dimensional tolerance is relatively low. Therefore, in some embodiments, a height adjustment device 5 is provided on the pulley assembly 2 to adjust the height of the pulley assembly 2 relative to the door body 6, thereby changing the total height of the door body 6 and the pulley assembly 2 to meet the requirements of different door frames. Specifically, in this Embodiment 1, the height adjustment device 5 includes an outer housing 51, an inner frame 52, and an adjustment member 53. The outer housing 51 has a first accommodation cavity 511. The inner frame 52 is movably assembled in the first accommodation cavity 511. Preferably, the inner frame 52 is provided with an inclined waist-shaped hole 522, and the outer housing 51 is provided with a sliding rod 512. The sliding rod 512 slides in the waist-shaped hole 522. The inner frame 52 has a second accommodation cavity 521, and the pulley bracket 21 is assembled in the second accommodation cavity 521. The adjustment member 53 is provided at one end of the inner frame 52. A limit block 524 is provided at one end of the second accommodation cavity 521 close to the inner frame 52. At least part of the adjustment member 53 is limited between the limit block 524 and one end of the inner frame 52. The adjustment member 53 is used to drive the inner frame 52 to displace the sliding rod 512 along the waist-shaped hole 522. When it is necessary to adjust the height of the pulley assembly 2, the user or installer operates the adjustment member 53 to drive the inner frame 52 to move. The inclined waist-shaped hole 522 on the inner frame 52 allows the sliding rod 512 to slide inside it. As the inner frame 52 moves, the sliding rod 512 also displaces along the path of the waist-shaped hole 522. This displacement causes the position of the pulley assembly 2 relative to the outer housing 51 to change, thereby achieving height adjustment; the height adjustment device 5 allows the user to adjust the height of the pulley assembly 2 according to actual needs to adapt to different installation environments or meet specific usage requirements.

[0052] Preferably, the adjusting member 53 includes a limiting block 531 and an adjusting screw 532. The limiting block 531 is limited within the inner frame 52, specifically between the limiting block 524 and one end of the inner frame 52. The head of the adjusting screw 532 is located outside one end of the outer housing 51, and the tail of the adjusting screw 532 sequentially passes through one end of the outer housing 51 and one end of the inner frame 52 and is screwed to the limiting block 531. By rotating the head of the adjusting screw 532, the length of the tail of the adjusting screw 532 passing through the limiting block 531 can be controlled, thereby completing the sliding of the inner frame 52 in the first receiving cavity 511 of the outer housing 51. During the sliding process, the sliding rod 512 is affected by the kidney-shaped hole 522 to raise the inner frame 52 relative to the outer housing 51, so as to realize the precise adjustment of the height of the pulley assembly 2 and meet different installation and use requirements; the screwed structure of the limiting block 531 and the adjusting screw 532 ensures the stability and reliability during the adjustment process, preventing adjustment failure caused by uneven force or loosening; the head design of the adjusting screw 532 is convenient for users or installers to operate, improving the convenience and efficiency of adjustment.

[0053] In some embodiments, in order to improve the smoothness between the sliding rail 11 and the pulley assembly 2, optionally, a brush 523 may also be provided on the inner frame 52 or the pulley frame 21, which can clean the floating dust and debris on the surface of the sliding rail 11, reduce the friction coefficient between the pulley assembly 2 and the sliding rail 11, make the pulley assembly 2 slide more smoothly during the sliding process, and reduce noise and vibration; it can also act as an oiling brush after applying lubricating oil, so that the lubricant forms a protective film between the pulley assembly 2 and the sliding rail 11, preventing direct contact and wear between metals. In this embodiment 1, the brush 523 is arranged on the brush holder 525, and the brush holder 525 is correspondingly clamped with the inner frame 52. Specifically, brush holder clamping blocks 5251 are arranged on both sides of the brush holder 525, and brush holder slots 526 are correspondingly arranged on the inner frame 52 for fixing the brush holder 525.

[0054] The present invention also relates to a phantom door system, including a door body 6, a door body frame 7, an upper guide wheel 8 and a guiding mechanism. The track profile 1 is arranged below the door body 6 and the door body frame 7. The upper guide wheel 8 is assembled on the door body frame 7 and is used to provide the upper part of the guiding force when the door body 6 is opened and closed. The pulley assembly 2 is fixed to the bottom of the door body 6, so that the lower part of the door body 6 provides the force to slide along the sliding rail 11, realizing the smooth, silent and stable opening and closing of the door body 6, and at the same time, the problem of the door body 6 being lifted by external forces will not occur during the operation process.

[0055] In a specific implementation scenario, the phantom door system is a bathroom phantom door system. The door frame 7 includes a side frame 71 and a bottom frame 72 capable of accommodating two folding doors. A fixed door 9 is fixedly arranged between one of the side frames 71 and the bottom frame 72. A door body 6 is arranged between the other side frame 71 and the bottom frame 72. The door body 6 is arranged out of alignment with the fixed door 9. The track profile 1 is arranged between the door body 6 and the bottom frame 72. The guide wheel is assembled on the side of the fixed door 9 away from the side frame 71. The periphery of the door body 6 further includes an upper frame 61, side frames 62, and a lower frame 63. The upper frame 61 is provided with an inwardly concave guide groove 611 capable of accommodating the guide wheel. The bottom of the lower frame 63 has an inwardly concave assembly groove 631. The pulley assembly 2 is assembled in the assembly groove 631. A horizontal limiting member 4 is assembled on one side of the pulley assembly 2 close to the end of the assembly groove 631. The inwardly concave assembly groove 631 can stably install and accommodate the pulley assembly 2 and the horizontal limiting member 4, improving the stability during the sliding process.

[0056] During installation, first install the side frame 71 and the bottom frame 72 at the bathroom exit. Then fix the fixed door 9 to the door body frame 7 and install guide wheels at the upper edge of the fixed door 9. Subsequently, install the track profile 1 above the bottom frame 72. It should be noted that the track profile 1 is arranged in a dislocation manner with respect to the fixed door 9, and the opening of the clamping groove in the sliding track 11 of the track profile 1 faces away from the fixed door 9. At this time, the phantom door body and the pulley assembly 2 can be assembled. The pulley assembly 2 and the horizontal limiting member 4 are installed in the assembly groove 631 of the lower border 63 of the phantom door body by screws or other means, and the horizontal limiting member 4 is closer to the end of the assembly groove 631 than the pulley assembly 2, so that the horizontal limiting member 4 can be operated and rotated from the side border 62 of the phantom door body. Preferably, two sets of the pulley assembly 2 and the horizontal limiting member 4 are provided, which can achieve the effect of stably supporting the phantom door body. After the phantom door body is assembled with the pulley assembly 2, it can be integrally assembled onto the door body frame 7. The specific operation is as follows: First, place the guide wheel in the guide groove 611 of the upper border 61 of the top surface of the phantom door body to limit the upper half of the phantom door body. Then push the lower half of the phantom door body towards the sliding track 11, that is, gradually push the roller 22 of the pulley assembly 2 into the sliding track 11, and engage the clamping strip 322 with the clamping groove 111. During this process, the rotating body 42 of the horizontal limiting member 4 rotates to make the abutting structure 421 parallel to the horizontal plane, avoiding the abutting structure 421 colliding with the sliding track 11 during the process of the roller 22 being inserted into the sliding track 11. Since the rolling surface 221 of the roller 22 is a concave arc structure, stable sliding in the normal state can be achieved between the roller 22 and the sliding track 11. Subsequently, the operating part 43 in the horizontal limiting member 4 is controlled from the side border 62 of the phantom door body, thereby rotating the rotating body 42 to make the abutting structure 421 perpendicular to and intersect with the horizontal plane, that is, the abutting structure 421 abuts against the side of the sliding track 11 opposite to the clamping groove 111. Thus, the entire installation of the phantom door is completed.

[0057] In summary, a guiding mechanism and a phantom door system provided by the present utility model have the following technical effects:

[0058] 1. By designing the sliding track 11 and the pulley assembly 2 and combining the clamping mechanism of the longitudinal limiting member 3 and the clamping groove 111, it is ensured that the pulley assembly 2 can always be closely attached to or close to the sliding track 11 during the sliding process, effectively preventing the phenomenon of the door body being lifted due to uneven force or external factors, such as wind force, uneven pushing and pulling force by humans, etc., thus significantly improving the sliding stability of the door body;

[0059] 2. The design of the vertical limiting member 3 and the horizontal limiting member 4 makes the connection between the pulley assembly 2 and the track more stable, reducing the problems of poor sliding or safety hazards caused by pulley loosening or deviation. This stable connection method not only extends the service life of the phantom door system but also improves the overall safety performance;

[0060] 3. The design of the guiding mechanism makes the installation process more standardized and normalized. Workers only need to install according to the established steps and requirements to ensure the correct connection and stability between the pulley assembly 2 and the track, thus reducing the stability problems caused by improper installation;

[0061] 4. Since the guiding mechanism effectively solves the problem of the door body lifting and enhances the connection stability between the pulley assembly 2 and the track, it can reduce the wear and damage caused by frequent opening and closing and long-term use, thereby extending the overall service life of the phantom door system.

[0062] The technical means disclosed in the solution of the present utility model are not limited to the technical means disclosed in the above embodiments, but also include the technical solutions composed of any combination of the above technical features. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present utility model.
