Description

Technical Field

[0001] This utility model relates to a sliding door, specifically a linked sliding door. Background Technology

[0002] Linked sliding doors use drive belts to open or close multiple door panels in unison. A linked sliding door consists of two end doors and a middle door. Each middle door panel is equipped with a drive belt, which runs along drive pulleys at both ends of the door panel. The end doors are connected to their respective drive belts via belt clips. They are widely used in homes, factories, shower rooms, and other similar applications.

[0003] Currently, most sliding doors use double tracks for movement. With double tracks, the lower track is prone to deformation and damage, affecting the use of the sliding door. It also increases manufacturing costs. On the other hand, with single tracks, the lower wheels are prone to misalignment, causing unnecessary damage to the door. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings and defects of the existing technology by providing a linkage sliding door. This linkage sliding door increases the tightness of the upper and lower parts of the sliding door body by adding tensioning wheels at both the top and bottom. This ensures that the sliding door body can be in contact with the wall for a long time. Furthermore, by increasing the number of wheels on the main walking wheel, the friction is increased, further ensuring the walking stability of the sliding door body.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a linkage sliding door, which includes a sliding door body, the sliding door body being composed of several door panels, each door panel having a tension wheel and a hanging wheel installed at its top, and the sliding door body being connected to an upper track via the hanging wheel, the bottom of the sliding door body having a lower frame, the lower frame having at least three, the lower frame located in the middle having a belt connecting mechanism installed, and the lower frame located on the outer side having a main traveling wheel installed.

[0023] See Figures 1-8 As shown, the technical solution adopted in this specific embodiment is as follows: it includes a sliding door body 4, which is composed of several door bodies. Each door body is equipped with a tensioning wheel 2 and a hanging wheel 3 at its top. The sliding door body 4 is connected to an upper track 1 through the hanging wheel 3. A lower frame 5 is installed at the bottom of the sliding door body 4. There are at least three lower frames 5. A belt connecting mechanism 8 is installed on the lower frame 5 located in the middle, and a traveling main wheel 7 is installed on the lower frame 5 located on the outer side.

[0024] More specifically, the upper track 1 has at least two sets, and adjacent upper tracks 1 are connected by track connectors 6. The track connector 6 includes a central vertical plate 62, an upper limit frame 61 fixedly connected to the top of the central vertical plate 62, and a bottom support plate 65 fixedly connected to the bottom of the central vertical plate 62. The two sides of the bottom support plate 65 are bent upward to form side limit frames 64, and a lower limit frame 63 is provided near the bottom support plate 65 on the central vertical plate 62. The upper track 1 is a commonly used double track, which can effectively save its manufacturing cost and can be used to install double track sliding doors, thus having a wider range of applications. However, if more than two doors need to be installed, two adjacent upper tracks 1 can be connected by the track connector 6. When the track connector 6 connects its upper track 1, its upper limit frame 61 and lower limit frame 63 can lock the upper track 1 to prevent the upper track 1 from shaking up and down. The bottom support plate 65 cooperates with the side limit frames 64 to restrict the upper track 1 and prevent the upper track 1 from loosening left and right. See also Figures 2-4 .

[0025] More specifically, the tensioning wheel 2 includes a door frame connecting bracket 26. Connecting grooves 25 are provided on both sides of the door frame connecting bracket 26, and a tension adjustment knob 24 is installed inside the door frame connecting bracket 26. A rotating shaft 23 is provided inside the door frame connecting bracket 26. The tension adjustment knob 24 cooperates with the rotating shaft 23. One end of the rotating shaft 23 is connected to a roller connecting plate 22, and a tensioning roller 21 is installed on the roller connecting plate 22. When installing the tensioning wheel 2, the operator can connect the door frame connecting bracket 26 to the door frame through the connecting grooves 25 and adjust the tension of the tensioning roller 21 using the tension adjustment knob 24. The tensioning wheel 2 at the top of the sliding door body 4 provides upward support, giving it a downward pressing force, thus solving the problem of the far end tilting up when the door is pushed. The tensioning wheel 2 at the bottom of the sliding door body 4 is to increase the number of wheels, increase friction, and prevent the main wheel from slipping and deviating.

[0026] More specifically, the hanging wheel 3 includes a door frame connector 31. Both sides of the door frame connector 31 protrude outwards to form limiting protrusions 35. An elastic connecting shaft 32 is installed on the door frame connector 31, and the other end of the elastic connecting shaft 32 is connected to a wheel body 34. A hanging wheel body 33 is provided on the wheel body 3. The hanging wheel 3 has an elastic connecting shaft 32, so that when the ground is uneven, especially when encountering a low point, the door leaf has a certain downward space. This ensures that the main wheel is always on the ground and will not be suspended in mid-air, thereby reducing the possibility of the door leaf deviating from its normal position.

[0027] More specifically, the belt connecting mechanism 8 includes positioning guide wheels 81, with at least two positioned guide wheels 81, all mounted on the lower frame 5. A connecting belt 82 is rotatably connected to the outer side of the positioning guide wheels 81. Belt connecting assemblies 83 are provided on both ends of the connecting belt 82, and the other end of the belt connecting assembly 83 is connected to the outer lower frame 5. When one door leaf is opened or closed, its corresponding lower frame 5 will drive its connecting belt 82 through the belt connecting assembly 83. The connecting belt 82 will then drive the other belt connecting assembly 83, thereby pushing the lower frame 5 of the other door leaf, thus enabling the two door leaves to open or close in a mutually connected manner.

[0028] More specifically, the main drive wheel 7 is equipped with at least four drive wheels 701 for movement, and both ends of the bottom of the lower frame 5 are also equipped with main drive wheels 7. The drive wheels 701 can increase the friction of the door leaf and ensure the stability of its sliding door body 4.

[0029] More specifically, the upper track 1 has an upper door body travel groove A for installing the hanging wheel body 33, and the lower frame 5 has a lower door body mounting groove B for installing the door frame.

[0030] The working principle of this utility model is as follows: When in use, the operator only needs to pull one side of the sliding door body 4. At this time, the lower frame 5 at the bottom of this sliding door body 4 will drive the connecting belt 82 to rotate through the belt connecting assembly 83. The connecting belt 82 will drive the other side of the sliding door body 4 to move, so that it can quickly open the linkage sliding door. At the same time, during use, the tensioning wheels 2 installed at the upper and lower ends of the sliding door body 4 can provide a certain support force for the sliding door body 4. The tensioning wheel 2 at the top of the sliding door body 4 can provide an upward support force, so that it has a downward pressing force, thereby solving the problem of the far end tilting up when pushing the door. The tensioning wheel 2 at the bottom of the sliding door body 4 is to increase the number of wheels, increase the friction, and prevent the main wheel from slipping and deviating. In addition, multiple sets of walking main wheels 7 are installed at the bottom of the lower frame 5, which can ensure the running stability of the sliding door body 4.

[0031] The above is only used to illustrate the technical solution of this utility model and not to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
