Description

Technical Field

[0001] This utility model relates to the field of shower room technology, specifically to a three-door linkage installation structure applied to a shower room. Background Technology

[0002] Shower rooms make full use of a corner of the room, clearly defining the shower area with a fence to form a relatively independent bathing space, which is becoming increasingly popular.

[0003] Referring to the three-section sliding door structure disclosed in the technical solution of CN202221973672.7, this technical solution includes at least three sliding door bodies. Each sliding door body includes a door body, a hanging wheel device located on the upper side of the door body, and a lower sliding block located on the lower side of the door body. The hanging wheel device is guided and connected to the upper guide rail, and the lower sliding block is slidably guided and connected to the lower guide rail. A linkage guide wheel is provided on the hanging wheel device of the middle sliding door body. The middle part of the transmission line is wound around the linkage guide wheel, and the two ends of the transmission line are respectively fixedly connected to the hanging wheel devices of the sliding door bodies located at both ends of the sliding direction. This technical solution can use the transmission line to enable at least three sliding door bodies to move in a coordinated manner to both sides of the sliding direction, increasing the opening size of the shower room door and reducing the space required for opening the door.

[0004] However, while this technical solution increases the door opening space, the entire door is supported by the hanging wheel device on the upper guide rail. This means that the upper guide rail has to bear the entire weight of the three doors. After long-term use, the upper guide rail is prone to deformation due to excessive load. This will not only cause the doors to slide poorly and affect the linkage effect between multiple doors, but may also shorten the service life of the sliding door structure. Utility Model Content

The movable rope seat is installed on the first hoisting wheel device and connected to the transmission rope.

[0011] In this utility model, the movable rope seat is provided with a rope threading hole for inserting the transmission rope and a rope locking screw hole communicating with the wall of the rope threading hole. The rope locking screw hole is internally threaded with a rope locking bolt for extending into the rope threading hole to lock the transmission rope.

[0012] In this utility model, the lower end of the central sliding door is provided with two moving limit components for guiding the left and right movement of the lower end of the side sliding door. Each moving limit component corresponds to one side sliding door, and the lower end of the side sliding door is guided and cooperated with the moving limit components.

[0013] In this utility model, the movable limiting component includes a lower limiting bracket and a side limiting wheel mounted on the lower limiting bracket. The lower limiting bracket is mounted on the bottom of the sliding door, and the side limiting wheel is rotatably mounted. The lower end of the sliding door is provided with a lower guide groove, and the side limiting wheel extends into the lower guide groove and is guided and engaged with the lower guide groove.

[0014] In this utility model, the bottom of the sliding component is provided with a mounting hole, and the upper part of the middle sliding door is provided with a mounting shaft. Each mounting hole corresponds to at least one mounting shaft, and the mounting shaft is detachably inserted into the mounting hole. The support pulley assembly is detachably placed on the lower guide rail and can move left and right along the lower guide rail.

[0015] In this utility model, the sliding assembly includes a sliding base and at least two sliding guide seats arranged from left to right on the sliding base. The mounting hole includes a sliding base hole provided on the sliding base. The sliding guide seat is slidably guided to the upper guide rail. The mounting hole also includes a quick-connect fitting hole provided on the sliding guide seat. The lower end of the quick-connect fitting hole corresponds to the sliding base hole.

[0033] Reference Figure 1-8A three-door linkage installation structure for use in a shower room includes an upper guide rail 1, a lower guide rail 2, and a door structure. The upper guide rail 1 and the lower guide rail 2 are fixedly connected by two fixed columns 3. The upper guide rail 1, the lower guide rail 2, and the two fixed columns 3 enclose a fixed door frame. The door structure includes a central sliding door 4 and two side sliding doors 5. The lower end of the central sliding door 4 is provided with at least two supporting pulley assemblies 6 arranged from left to right to support the left and right movement of the central sliding door 4. The supporting pulley assemblies 6 are guided and fitted on the lower guide rail 2. A sliding assembly 7 is guided and connected on the upper guide rail 1. The upper end of the central sliding door 4 is detachably fitted on the sliding assembly 7. The upper end of the side sliding door 5 is provided with a hoisting pulley device 8 for suspending it on the upper guide rail 1. The hoisting pulley device 8 is guided and fitted on the upper guide rail 1. The central sliding door 4 and the side sliding door 5 are linked by a transmission rope 9. The sliding assembly 7 is provided with a linkage guide wheel 70. There are two linkage guide wheels 70 distributed from left to right. The transmission rope 9 is wound around the linkage guide wheel 70. The hoisting pulley devices 8 of the two side sliding doors 5 are both connected to the transmission rope 9. The transmission rope 9 is preferably a steel wire rope.

[0034] In this embodiment, a support pulley assembly 6 is installed at the bottom of the central sliding door 4 and guided to the lower guide rail 2. The support pulley assembly 6 can bear the weight of the central sliding door 4. This structure allows the upper guide rail 1 to bear only the weight of the two side sliding doors 5, effectively reducing the load on the upper guide rail 1 and avoiding deformation of the upper guide rail 1 due to excessive long-term load. This ensures the structural stability of the upper guide rail 1 and guarantees the smooth sliding of the door. At the same time, the sliding assembly 7 connected to the upper end of the central sliding door 4 is equipped with a linkage guide wheel 70, and the transmission rope 9 is wound around the linkage guide wheel 70. The lifting pulley devices 8 of the two side sliding doors 5 are both connected to the transmission rope 9, thereby realizing the three-door linkage, allowing users to use the three-door linkage function normally and ensuring the effective implementation of the opening and closing action of the shower room.

[0035] In this embodiment, the hoisting pulley device 8 includes a movable rope seat 81 for connecting the transmission rope 9, a first hoisting pulley device 82 and a second hoisting pulley device 83 arranged along the moving direction of the side sliding door 5. The lower parts of the first hoisting pulley device 82 and the second hoisting pulley device 83 are both fixed to the upper part of the side sliding door 5, and the upper parts of the first hoisting pulley device 82 and the second hoisting pulley device 83 are both guided and fitted on the upper guide rail 1. The second hoisting pulley device 83 is located at the end of the side sliding door 5 away from the middle sliding door 4. The second hoisting pulley device 83 integrates a buffer 831. The upper guide rail 1 is provided with a trigger block 10 for triggering the buffer 831. The combination of the buffer 831 and the trigger block 10 realizes the buffering when the side sliding door 5 is closed. The first hoisting pulley device 82, the second hoisting pulley device 83, the buffer 831 and the trigger block 10 described above are existing conventional technologies, and therefore will not be described in detail.

[0036] Furthermore, the first hanging wheel device 82 is located near the middle sliding door 4, and the movable rope seat 81 is installed on the first hanging wheel device 82 and connected to the transmission rope 9. Specifically, the movable rope seat 81 is fixed to the first hanging wheel frame of the first hanging wheel device 82 by bolt connection. The movable rope seat 81 is provided with a rope hole 811 for inserting the transmission rope 9 and a locking screw hole communicating with the wall of the rope hole 811. The locking screw hole is internally threaded with a locking bolt 812 for extending into the rope hole 811 to lock the transmission rope 9. During installation, the transmission rope 9 is first inserted into the rope hole 811, and then the locking bolt 812 is tightened so that the locking bolt 812 abuts against the transmission rope 9, thereby realizing the combination and fixation between the movable rope seat 81 and the transmission rope 9.

[0037] In this embodiment, the lower end of the central sliding door 4 is provided with two moving limit components 11 for guiding the left and right movement of the lower end of the side sliding door 5. Each moving limit component 11 corresponds to one side sliding door 5, and the lower end of the side sliding door 5 is guided and cooperated with the moving limit component 11. Specifically: The movable limiting component 11 includes a lower limiting bracket 111 and a side limiting wheel 112 mounted on the lower limiting bracket 111. The lower limiting bracket 111 is bolted to the bottom of the sliding door 4. The side limiting wheel 112 is rotatably mounted. The lower end of the sliding door 5 is provided with a lower guide groove 501. The side limiting wheel 112 extends into the lower guide groove 501 and guides and cooperates with the lower guide groove 501. The front and rear ends of the rolling face of the side limiting wheel 112 correspond to the front and rear groove surfaces of the lower guide groove 501, respectively. Thus, when the sliding door 5 moves left and right, it is limited by the side limiting wheel 112, thereby reducing the back and forth swaying of the sliding door 5 when it moves left and right, and improving the stability of the sliding door 5 when it moves left and right.

[0038] In this embodiment, the bottom of the sliding component 7 is provided with two mounting holes distributed from left to right, and the upper part of the sliding door 4 is provided with a mounting shaft 12. Each mounting hole corresponds to at least one mounting shaft 12. The mounting shaft 12 is detachably inserted into the mounting hole, thereby realizing the detachable combination of the upper end of the sliding door 4 and the sliding component 7. There are two supporting pulley components 6, which are distributed from left to right at the lower part of the sliding door 4. The supporting pulley components 6 are detachably placed on the lower guide rail 2 and can move left and right along the lower guide rail 2, thereby realizing the front and rear limit of the lower end of the sliding door 4 and providing support for the sliding door 4. The bottom of the sliding component 7 is provided with an installation hole, which allows workers to visually observe the position of the installation hole. At the same time, the top of the sliding door 4 is provided with an installation shaft 12. During installation, the installation shaft 12 is inserted into the installation hole to achieve the initial positioning of the upper part of the sliding door 4. Then, the support pulley component 6 is placed on the lower guide rail 2 to complete the overall installation. This effectively reduces the difficulty of installation alignment, makes the installation process simpler and more convenient, and achieves the goal of improving installation efficiency.

[0039] In this embodiment, the sliding assembly 7 includes a sliding base 71 and at least two sliding guide seats 72 arranged from left to right on the sliding base 71. The sliding guide seats 72 and the sliding base 71 are fixed together by a first bolt. The mounting hole includes a sliding base hole 711 provided on the sliding base 71, which extends through the sliding base 71 from bottom to top. The sliding guide seat 72 is slidably guided to the upper guide rail 1. The mounting hole also includes a quick-connect fitting hole provided on the sliding guide seat 72, which extends through the sliding guide seat 72 from bottom to top. The lower end of the quick-connect fitting hole corresponds to the sliding base hole 711. The diameter of the sliding base hole 711 is larger than the diameter of the quick-connect fitting hole. Thus, when the mounting shaft 12 is inserted into the mounting hole, the mounting shaft 12 first passes through the sliding base hole 711 and then is inserted into the quick-connect fitting hole, thereby realizing the insertion and positioning between the mounting shaft 12 and the sliding assembly 7.

[0040] In this embodiment, each sliding guide seat 72 is equipped with a corresponding guide wheel bracket 73, and each guide wheel bracket 73 is equipped with a rotatable linkage guide wheel 70, allowing the linkage guide wheel 70 to be rotatably positioned relative to the guide wheel bracket 73. Furthermore, the circumferential surface of the linkage guide wheel 70 is provided with a groove for positioning the transmission rope 9, and the transmission rope 9 is at least partially wound in the groove to prevent the transmission rope 9 from slipping off the linkage guide wheel 70, ensuring the stability of the three-door linkage. Further still, the transmission rope 9 is connected end-to-end based on one of the movable rope seats 81 to form a transmission loop, with two linkage guide wheels 70 located within the transmission loop, and the transmission rope 9 simultaneously wound around both linkage guide wheels 70.

[0041] In this embodiment, the upper guide rail 1 is provided with a guide mounting groove 101. The guide mounting groove 101 is provided with two side door guide grooves 102 distributed front and rear and a middle door guide groove 103 located between the two side door guide grooves 102. Each side sliding door 5 corresponds to one side door guide groove 102. The upper parts of the first hanging wheel device 82 and the second hanging wheel device 83 on the side sliding door 5 are guided and fitted in the side door guide groove 102. The front groove surface and the rear groove surface of the side door guide groove 102 are provided with side guide protrusions 104 for guiding and fitting with the lifting rollers of the first hanging wheel device 82 and the second hanging wheel device 83, so that the first hanging wheel device 82 and the second hanging wheel device 83 are slidably mounted on the upper guide rail 1.

[0042] Furthermore, the upper part of the sliding guide seat 72 extends into the middle door guide groove 103 and can move left and right along the guide of the middle door guide groove 103. The upper front and upper rear sides of the sliding guide seat 72 are provided with quick-installation guide parts 722. The front and rear sides of the groove opening at the lower part of the middle door guide groove 103 are provided with support protrusions 106 supported on the quick-installation guide parts 722. Furthermore, the quick-installation guide parts 722 on the front and rear sides are respectively close to the front and rear sides of the middle door guide groove 103, thereby limiting the sliding guide seat 72 in the front and rear directions through the front and rear sides of the middle door guide groove 103, thereby reducing the back and forth shaking of the sliding guide seat 72 when it moves left and right.

[0043] In this embodiment, a mating mounting groove 105 is provided above the side door guide groove 102. The upper end of the trigger block 10 is mated in the mating mounting groove 105 and fixed to the upper guide rail 1 by a trigger bolt, thereby realizing the installation of the trigger block 10.

[0044] In this embodiment, the lower guide rail 2 includes a lower fixed beam 21 and a strip rail 22 disposed on the lower fixed beam 21. The guide roller of the support pulley assembly 6 is provided with a rolling groove. The upper part of the strip rail 22 is a convex arc portion that extends into the rolling groove and matches the rolling groove. By cooperating with the rolling groove, the convex arc portion can strengthen the front and rear limiting function of the guide roller of the support pulley assembly 6, making it less likely for the guide roller of the support pulley assembly 6 to detach from the strip rail 22.

[0045] In this embodiment, both the side sliding door 5 and the center sliding door 4 include a movable door frame and a door panel disposed within the movable door frame. The lower end of the first hanging wheel frame of the first hanging wheel device 82 and the lower end of the second hanging wheel frame of the second hanging wheel device 83 are both bolted together and installed on the upper end of the movable door frame of the side sliding door 5. The lower guide groove 501 is disposed on the bottom of the movable door frame of the side sliding door 5.

[0046] Furthermore, the bottom of the sliding door frame of the central sliding door 4 is provided with a pulley mounting groove 401, and the upper part of the supporting pulley assembly 6 is installed in the pulley mounting groove 401 by pulley bolts, thereby reducing the exposure of the supporting pulley assembly 6; the bottom of the mounting shaft 12 is provided with a shaft base plate 121, and the shaft base plate 121 is fixedly installed on the upper end of the sliding door frame of the central sliding door 4 by bolt connection, thereby completing the installation of the mounting shaft 12.

[0047] The above description is only a preferred embodiment of the present utility model. Any technical solution that achieves the purpose of the present utility model by essentially the same means shall fall within the protection scope of the present utility model.
