Description

Technical Field

[0001] The present invention relates to the technical field related to ghost doors, and in particular to a guiding mechanism and a ghost door system. Background Art

[0002] In modern home and commercial space design, ghost doors, also known as hidden track sliding doors or barn doors, are popular for their unique hidden track design and simple visual effects. However, in the actual installation and use process, the stability of ghost doors has gradually become the focus of industry attention. Especially in the installation process, if workers fail to follow strict operating specifications or use substandard materials, it may bury hidden dangers for subsequent use.

[0003] Specifically, the stability problem of ghost doors is mainly reflected in the upward lifting phenomenon caused by uneven force that may occur during the movement of the door body. This phenomenon is often caused by the loose installation of the pulley and the unreasonable setting of the gap between the door panel and the wall. When the pulley 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 easily disturbed by external factors during the sliding process, such as wind force, uneven human push and pull force, etc., which causes the door body to lift up, affecting the use effect and safety.

[0004] In addition, long-term use and frequent opening and closing of ghost doors will also have an adverse effect on their stability. Over time, the wear of the pulleys and tracks increases, and the load-bearing capacity of the door body gradually weakens, further increasing the risk of the door body lifting. Especially when the door body is subjected to a large impact force or suffers accidental damage during use, its stability problem becomes more prominent. Summary of the invention

[0005] In order to overcome at least one of the defects of the prior art, the present invention provides a guide mechanism and a ghost door system, which can solve the problem of door body lifting, thereby improving the sliding stability of the door body and further increasing the service life.

[0006] The technical solution adopted by the present invention to solve the problem is:

[0007] A guide mechanism comprises: a track profile, on which a sliding rail is provided, and at least one side of the sliding rail is provided with a locking groove; a pulley assembly, which is used to be assembled to the bottom of a door body, and the pulley assembly comprises a pulley frame and a roller, the roller is rotatably connected in the pulley frame, and the pulley assembly is slidably arranged on the sliding rail; a longitudinal limit member, the longitudinal limit member is assembled in the pulley frame, and the longitudinal limit member partially extends from the pulley frame and is engaged with the locking groove, so that when the pulley assembly slides along the sliding rail, the rolling surface of the roller is always in contact with or close to the sliding rail.

[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 abutment structure protrudes from the surface of the rotating body by a large height, when the rotating body is adjusted to the position of abutting against the sliding rail, the abutment structure can fully contact and press the other side of the sliding rail. This close contact not only limits the horizontal movement of the pulley assembly, but also provides sufficient friction to prevent the door body from sliding or shaking when subjected to external force.

[0015] Furthermore, the longitudinal limit member includes: a second assembly body, which is assembled in the pulley frame; a limit body, which is fixedly connected to the second assembly body, and the limit body is provided with an avoidance groove toward the direction of the sliding rail, and the two sides of the avoidance groove are respectively spaced apart from the two sides of the sliding rail, and a clamping strip is also provided 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 slide rail and reducing friction and wear. At the same time, the avoidance groove also provides a certain space, so that the pulley assembly can have a certain buffer and adaptability when subjected to external force. The design of the clamping strip enables the limiter to be firmly fixed on the slide rail to prevent the pulley assembly from longitudinally deviating or falling off during the sliding process. At the same time, the clamping method of the clamping strip and the clamping groove also provides a convenient installation and disassembly method, improving work efficiency.

[0017] Furthermore, the pulley assembly also includes a height adjustment device, which includes: an outer shell, the outer shell having a first accommodating cavity; an inner frame, the inner frame is movably assembled in the first accommodating cavity, the inner frame has a second accommodating cavity, and the pulley frame is assembled in the second accommodating cavity; an adjusting member, the adjusting member is arranged at one end of the inner frame; wherein, the inner frame is provided with an inclined waist-shaped hole, the outer shell is provided with a sliding rod, the sliding rod is slidably arranged in the waist-shaped hole, and the adjusting member is used to drive the inner frame to make the sliding rod move along the waist-shaped hole.

[0018] By adopting the above solution, when the height of the pulley assembly needs to be adjusted, the user or installer drives the inner frame to move by operating the adjustment piece. The inclined waist-shaped hole on the inner frame allows the slide bar to slide inside it. As the inner frame moves, the slide bar also moves along the path of the waist-shaped hole. This displacement causes the position of the pulley assembly relative to the outer shell to change, thereby achieving 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] Furthermore, the adjusting member includes: a limit block, which is limited within the inner frame; an adjusting screw, the head of which is located outside one end of the outer shell, and the tail of which passes through one end of the outer shell and one end of the inner frame in sequence and is threadedly connected to the limit block.

[0020] By adopting the above scheme, the height of the pulley assembly can be accurately adjusted by rotating the adjusting screw to meet different installation and use requirements; the screw connection structure of the limit block and the adjusting screw ensures stability and reliability during the adjustment process, and prevents adjustment failure due to uneven force or looseness; the head design of the adjusting screw is convenient for users or installers to operate, thereby improving the convenience and efficiency of adjustment.

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

[0022] By adopting the above scheme, the floating sediment and debris on the surface of the slide rail can be cleaned, the friction coefficient between the pulley assembly and the slide rail can be reduced, the pulley assembly can slide more smoothly, and the noise and vibration can be reduced; it can also act as an oiling brush after applying lubricating oil, so that the lubricant forms a protective film between the pulley assembly and the slide rail to prevent direct contact and wear between metals.

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

[0024] By adopting the above solution, the door body can be opened and closed smoothly and quietly, and the door body will not be lifted up due to external forces during operation.

[0025] Furthermore, the door body is surrounded by an upper frame, a side frame 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 limit piece 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 limit member, thereby improving the stability during the sliding process.

[0027] In summary, the guiding mechanism and ghost door system provided by the present invention have the following technical effects:

[0028] 1. By designing the sliding rail and pulley assembly, and combining the clamping mechanism of the longitudinal limiter and the clamping groove, it is ensured that the pulley assembly can always be closely fitted or close to the sliding rail during the sliding process, effectively preventing the door body from lifting up due to uneven force or external factors such as wind force and uneven human push and pull force, thereby significantly improving the sliding stability of the door body;

[0029] 2. The design of the longitudinal limiter makes the connection between the pulley assembly and the track more stable, reducing the sliding problems or safety hazards caused by loose or offset pulleys. This stable connection method not only extends the service life of the ghost door system, but also improves the overall safety performance;

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

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

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0046] Embodiment 1 of the present invention refers to Figure 1-Figure 9 As shown, a guide mechanism is disclosed, which is applied to the bottom of the door body 6. In this embodiment 1, it specifically refers to the bottom of the door body 6 of the ghost door. In other embodiments, it can also be applied to the bottom of other door and window structures, which is not specifically limited here; the guide mechanism includes a track profile 1, a pulley assembly 2 and a longitudinal limiter 3, the track profile 1 is provided with a sliding rail 11, at least one side of the sliding rail 11 is provided with a positioning groove 111, the pulley assembly 2 is used to be assembled to the bottom of the door body 6, and the pulley assembly 2 includes a pulley frame 21 and a roller 2 2, the roller 22 is rotatably connected to the pulley frame 21, the pulley assembly 2 is slidably arranged on the sliding rail 11, the longitudinal limit member 3 is assembled in the pulley frame 21, and the longitudinal limit member 3 partially extends from the pulley frame 21 and is engaged with the locking groove 111, so that when the pulley assembly 2 slides along the sliding rail 11, the rolling surface 221 of the roller 22 is always in contact with or close to the sliding rail 11. By setting the sliding rail 11 and the pulley assembly 2, it is ensured that the door body can move smoothly along the track when sliding. In particular, the design of the longitudinal limit member 3, which is assembled in the pulley frame 21 and extends from the pulley frame 21 to engage with the locking groove 111 on the track, allows the rolling surface 221 of the roller 22 to always fit or be close to the sliding rail 11 when the pulley assembly 2 slides along the sliding rail 11, reducing the lifting phenomenon caused by uneven force or external factors; it not only enhances the stability of the connection between the pulley assembly 2 and the track, but also makes the installation process more standardized, reducing stability problems caused by improper installation.

[0047] During installation, when the two sides of the slide rail 11 are provided with the positioning grooves 111, it is necessary to first install the pulley assembly 2 from one end of the slide rail 11 before assembling the track profile 1, and then fix the track profile 1 on the ground or above the bottom of the door frame 7, and finally connect the pulley assembly 2 to the bottom of the door body 6, at which time the door body 6 can slide along the slide rail 11 to achieve the effect of opening and closing the door. When the positioning grooves 111 are only provided on one side of the slide rail 11, the pulley assembly 2 can be pushed horizontally onto the slide rail 11 on the side of the positioning grooves 111 of the slide rail 11, so there is no need to limit the installation order of the track profile 1 and the pulley assembly 2, and after all are installed, the door body 6 can slide along the slide rail 11 to achieve the effect of opening and closing the door. In this embodiment 1, the positioning grooves 111 are only provided on one side of the slide rail 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, in order to better achieve longitudinal limiting with the positioning groove 111, the structure of the longitudinal limiting member 3 is further refined, and 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 frame 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, and the limiting body 32 is provided with an avoidance groove 321 toward the direction of the sliding rail 11, and the two sides of the avoidance groove 321 are respectively spaced apart from the two sides of the sliding rail 11, and a clamping strip 322 is further provided on one side of the avoidance groove 321, and the clamping strip 322 is clamped with the positioning groove 111. The design of the avoidance groove 321 allows the pulley assembly 2 to have a partial structure that can 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, so that the pulley assembly 2 can have a certain buffer and adaptability when subjected to external force, and the design of the clamping strip 322 enables the limiter 32 to be firmly fixed on the slide rail 11, preventing the pulley assembly 2 from longitudinally deviating 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, thereby improving work efficiency.

[0051] During the actual installation process, since the heights of actual door frames are different, the size of the door body 6 needs to be accurately determined when installing it to improve the aesthetics after installation without causing trouble to the installation. However, the above effect cannot usually be achieved well, and the size tolerance is low. For this reason, 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 needs of different door frames. Specifically, in this embodiment 1, the height adjustment device 5 includes an outer shell 51, an inner frame 52 and an adjusting member 53, the outer shell 51 has a first accommodating cavity 511, the inner frame 52 is movably assembled in the first accommodating cavity 511, preferably, the inner frame 52 is provided with an inclined waist-shaped hole 522, the outer shell 51 is provided with a sliding rod 512, the sliding rod 512 is slidably arranged in the waist-shaped hole 522, the inner frame 52 has a second accommodating cavity 521, the pulley frame 21 is assembled in the second accommodating cavity 521, and the adjusting member 53 is arranged at one end of the inner frame 52. A limit block 524 is provided in the second accommodating cavity 521 near one end of the inner frame 52, and the adjusting member 53 is at least partially limited between the limit block 524 and one end of the inner frame 52. The adjusting member 53 is used to drive the inner frame 52 to make the slide bar 512 move along the waist-shaped hole 522. When it is necessary to adjust the height of the pulley assembly 2, the user or the installer drives the inner frame 52 to move by operating the adjusting member 53. The inclined waist-shaped hole 522 on the inner frame 52 allows the slide bar 512 to slide inside it. As the inner frame 52 moves, the slide bar 512 also moves along the path of the waist-shaped hole 522. This displacement causes the position of the pulley assembly 2 relative to the outer shell 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 limit block 531 and an adjusting screw 532, the limit block 531 is limited within the inner frame 52, specifically between the limit 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 shell 51, and the tail of the adjusting screw 532 passes through one end of the outer shell 51 and one end of the inner frame 52 in sequence and is screwed to the limit block 531. By rotating the head of the adjusting screw 532, the length of the tail of the adjusting screw 532 passing through the limit block 531 can be controlled, thereby completing the sliding of the inner frame 52 in the first accommodating cavity 511 in the outer shell 51. During the sliding process, the sliding rod 512 is acted upon by the waist-shaped hole 522 to raise the inner frame 52 relative to the outer shell 51, thereby achieving precise adjustment of the height of the pulley assembly 2 to meet different installation and use requirements; the screw connection structure of the limit block 531 and the adjusting screw 532 ensures stability and reliability during the adjustment process, and prevents adjustment failure caused by uneven force or looseness; the head design of the adjusting screw 532 is convenient for users or installers to operate, thereby 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 can be provided on the inner frame 52 or the pulley frame 21, which can clean the floating and sundries 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 smoother during the sliding process, 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 to prevent direct contact and wear between metals. In this embodiment 1, the brush 523 is provided on the brush holder 525, and the brush holder 525 is correspondingly engaged with the inner frame 52. Specifically, brush holder blocks 5251 are provided on both sides of the brush holder 525, and the inner frame 52 is provided with brush holder slots 526 corresponding to the brush holder blocks 5251 for fixing the brush holder 525.

[0054] The present invention also relates to a ghost door system, including a door body 6, a door frame 7, an upper guide wheel 8 and a guide mechanism, wherein the track profile 1 is arranged below the door body 6 and the door frame 7, and the upper guide wheel 8 is assembled on the door frame 7, and is used to provide a guiding force for the upper part of the door body 6 when opening and closing. 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 a force to slide along the sliding rail 11, thereby achieving the stability, smoothness and silence of the door body 6 during the opening and closing process, and at the same time, the door body 6 will not be affected by external forces and will not be lifted up during operation.

[0055] In a specific implementation scenario, the ghost door system is a bathroom ghost door system, the door body frame 7 includes a side frame 71 and a bottom frame 72 that can accommodate two doors to be folded and placed, a fixed door 9 is fixedly arranged between one side frame 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 and the fixed door 9 are staggered, the track profile 1 is arranged between the door body 6 and the bottom frame 72, and the guide wheel is assembled on a side of the fixed door 9 away from the side frame 71. On the side, the door body 6 also includes an upper frame 61, a side frame 62 and a lower frame 63. The upper frame 61 is provided with a concave guide groove 611 capable of accommodating a guide wheel. The bottom of the lower frame 63 has a concave assembly groove 631. The pulley assembly 2 is assembled in the assembly groove 631. A horizontal limit member 4 is assembled on one side of the pulley assembly 2 close to the end of the assembly groove 631. The concave assembly groove 631 can stably install and accommodate the pulley assembly 2 and the horizontal limit member 4, thereby improving stability during sliding.

[0056] During installation, first install the side frame 71 and the bottom frame 72 to the bathroom exit, then fix the fixed door 9 on the door frame 7 and install the guide wheel at the edge of the upper part of the fixed door 9, then install the track profile 1 above the bottom frame 72. It should be noted that the track profile 1 and the fixed door 9 are staggered, and the opening of the clamping groove in the sliding rail 11 of the track profile 1 faces the side away from the fixed door 9; at this time, the ghost door body and the pulley assembly 2 can be assembled, and the pulley assembly 2 and the horizontal limiter 4 are installed in the assembly groove 631 of the lower frame 63 of the ghost door body by screws or other means, and the horizontal limiter 4 is closer to the end of the assembly groove 631 than the pulley assembly 2, so that the horizontal limiter 4 can be operated and rotated from the side frame 62 of the ghost door body. Preferably, the pulley assembly 2 and the horizontal limiter 4 are both provided with two groups, which can play the effect of stabilizing the support of the ghost door body. After the ghost door body and the pulley assembly 2 are assembled, they can be integrally assembled to the door frame 7. The specific operation is as follows: first, place the guide wheel in the guide groove 611 of the upper frame 61 on the top surface of the ghost door body to limit the upper half of the ghost door body, and then push the lower half of the ghost door body toward the slide rail 11, that is, gradually push the roller 22 of the pulley assembly 2 onto the slide rail 11, and engage the clamping strip 322 with the clamping groove 111; in this process, the rotating body 42 of the horizontal limiting member 4 is rotated to make the abutment structure 421 and the horizontal surface Keep parallel to avoid collision between the contact structure 421 and the slide rail 11 during the process of the roller 22 being installed into the slide rail 11. Since the rolling surface 221 of the roller 22 is a concave arc structure, it can achieve stable sliding with the slide rail 11 under normal conditions. Then, the operating part 43 in the horizontal stopper 4 is manipulated from the side frame 62 of the ghost door body, so as to rotate the rotating body 42, so that the contact structure 421 is perpendicular to the horizontal plane, that is, the contact structure 421 cuts off the side of the slide rail 11 opposite to the positioning groove 111. Thus, the installation of the ghost door is completed.

[0057] In summary, the guiding mechanism and ghost door system provided by the present invention have the following technical effects:

[0058] 1. By designing the sliding rail 11 and the pulley assembly 2, and combining the clamping mechanism of the longitudinal limiter 3 and the clamping groove 111, it is ensured that the pulley assembly 2 can always be closely fitted or close to the sliding rail 11 during the sliding process, effectively preventing the door body from lifting up due to uneven force or external factors such as wind force and uneven human push and pull force, thereby significantly improving the sliding stability of the door body;

[0059] 2. The design of the longitudinal limiter 3 and the horizontal limiter 4 makes the connection between the pulley assembly 2 and the track more stable, reducing the sliding problems or safety hazards caused by loose or offset pulleys. This stable connection method not only extends the service life of the ghost door system, but also improves the overall safety performance;

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

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

[0062] The technical means disclosed in the scheme of the present invention are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical schemes composed of any combination of the above-mentioned technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also regarded as the protection scope of the present invention.
