[0001] The utility model relates to the technical field of doors and windows, and specifically discloses a lower load-bearing side-sliding door with a damper. Background Art
[0002] A side-sliding door refers to a door whose door body can move between two adjacent tracks connected at an angle. Generally, it includes a movable door body, a door rail bracket, and a pulley assembly. The pulley assembly includes a first pulley assembly and a second pulley assembly. The door rail bracket is formed by splicing a first track and a second track. The movable door body hoists the door rail bracket through the first pulley assembly and the second pulley assembly, so that the movable door body can side-slide along the door rail bracket, greatly saving the space occupied when pushing open the movable door body and meeting the space requirements of small living rooms.
[0003] The side-sliding door also includes an upper load-bearing door and a lower load-bearing door. For example, Chinese Patent No. CN221236591U discloses a sliding structure for a side-sliding door and the side-sliding door. The lower load-bearing door has a smoother sliding effect. However, the existing structure of the lower load-bearing side-sliding door is not convenient for setting a buffer structure. When pushing open the movable door body, due to the inertial effect of the pulley, the pulley is likely to collide with the inner wall of the guide rail bracket, and after long-term use, the pulley will be damaged due to excessive impacts. Summary of the Utility Model
[0004] To overcome at least one defect of the above-mentioned prior art, the utility model provides a lower load-bearing side-sliding door with a damper. By setting a damper on the upper door rail and then setting a guide wheel and a trigger member for triggering the damper buffer on the upper side of the side-sliding door body, on the premise of not changing the overall structure of the existing lower load-bearing side-sliding door, the space of the upper door rail is fully utilized to set the damper. Thus, when pushing the side-sliding door body, the damper in the upper door rail can be used for buffering, avoiding the collision between the pulley and the inner wall of the lower guide rail bracket, and further ensuring the normal service life of the pulley.
[0005] The technical solution adopted by the utility model to solve its problems is as follows:
[0006] A side-sliding door rail assembly, including:
[0007] An upper door rail, which has a guide track on it, and a damper is arranged in the guide track;
[0008] A side-sliding door body, which has a guide wheel and a trigger member on its upper side. The guide wheel and the trigger member are both arranged in the guide track, and the trigger member is arranged at a height offset from the guide wheel. The trigger member is used to cooperate with the damper to buffer the side-sliding door body.
[0009] Specifically, an installation opening is formed on the upper side of the upper door rail, and the installation opening penetrates the guide track. The damper is installed in the guide track through the installation opening.
[0010] Specifically, the damper is detachably installed with a cover plate, and the cover plate is detachably installed on the installation opening.
[0011] Specifically, the damper is provided with a connection hole, and the cover plate is provided with a plug hole corresponding to the connection hole. By inserting a connecting piece through the connection hole and the plug hole, the cover plate is installed on the damper.
[0012] Specifically, the cover plate is extended with an installation part, and the installation part is provided with an adjustment groove corresponding to the upper door rail. The upper door rail is provided with an adjustment key corresponding to the adjustment groove. When the damper is detachably installed on the installation opening, the adjustment key is slidably fitted in the adjustment groove, and the position of the damper in the guide rail is adjusted by adjusting the position of the adjustment key in the adjustment groove.
[0013] Specifically, the installation part is further provided with a fixing hole corresponding to the upper door rail, and the upper door rail is provided with a fixing position corresponding to the fixing hole. By inserting a fixing piece through the fixing hole and the fixing position, the damper is fixed on the upper door rail.
[0014] Specifically, the trigger member is arranged above the guide wheel.
[0015] Specifically, the trigger structure of the damper is arranged on one side in the horizontal direction of the trigger member.
[0016] Specifically, the structure of the trigger member is a cylindrical structure.
[0017] Specifically, the trigger member is coaxially arranged with the guide wheel.
[0018] In summary, compared with the prior art, the lower load-bearing side-sliding door with a damper provided by the present utility model has the following technical effects:
[0019] By arranging a damper in the guide rail of the upper door rail, and then arranging a guide wheel and a trigger member on the upper side of the side-sliding door body, so that both the guide wheel and the trigger member are arranged in the guide rail, and the trigger member and the guide wheel are arranged with a height offset. The trigger member is used to cooperate with the damper to buffer the side-sliding door body, so as to utilize the space of the upper door rail to arrange the damper.

[0035] 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 the present utility model belongs. The terms used in the specification of the present utility model are only for describing specific embodiments and are not intended to limit the present utility model.
[0036] Embodiment 1
[0037] Specifically, please refer to Figures 1 to 10 As shown, the present utility model discloses a lower-bearing side-sliding door with damping, including: an upper door rail 1 and a side-sliding door body 3.
[0038] Specifically, the upper door rail 1 has a guiding track 11, and a damper 21 is arranged in the guiding track 11; the upper side of the side-sliding door body 3 has a guiding wheel 32 and a triggering member 31. Both the guiding wheel 32 and the triggering member 31 are arranged in the guiding track 11, and the triggering member 31 is arranged at a height offset from the guiding wheel 32. The triggering member 31 is used to cooperate with the damper 21 to buffer the side-sliding door body 3.
[0039] Through the above settings, the space of the upper door rail 1 can be utilized to arrange the damper 21, so as to achieve the buffering of the pulley without changing the overall structure of the existing lower-bearing side-sliding door. When the side-sliding door body 3 is pushed, the triggering member 31 slides along the guiding track 11 to the damper 21 with the guiding wheel 32, so as to trigger the damper 21 in the upper door rail 1 to buffer, avoiding the collision between the pulley and the inner wall of the lower guide rail bracket, and thus ensuring the normal service life of the pulley.
[0040] Furthermore, an installation opening 10 is formed in the upper side of the upper door rail 1. The installation opening 10 penetrates through the guiding rail 11. The damper 21 is installed in the guiding rail 11 through the installation opening 10, realizing the detachable installation of the damper 21. This avoids the inconvenience of having to disassemble the upper door rail 1 when maintaining the damper 21. Only by disassembling the damper 21 from the installation opening 10 can maintenance be carried out, greatly improving the convenience of installing and maintaining the damper 21.
[0041] Specifically, a cover plate 22 is detachably installed on the damper 21, and the cover plate 22 is detachably installed in the installation opening 10, thereby realizing the detachable installation of the damper 21 through a simpler structure. More specifically, the damper 21 is provided with a connection hole 211, and the cover plate 22 is provided with a plug hole 221 corresponding to the connection hole 211. By inserting a connecting member 23 through the connection hole 211 and the plug hole 221, the cover plate 22 is installed on the damper 21. Further, the cover plate 22 is extended with an installation portion 222, and an adjustment groove 223 is provided on the installation portion 222 corresponding to the upper door rail 1. The upper door rail 1 is provided with an adjustment key corresponding to the adjustment groove 223. When the damper 21 is detachably installed in the installation opening 10, the adjustment key is slidably fitted in the adjustment groove 223. By adjusting the position of the adjustment key in the adjustment groove 223, the position of the damper 21 in the guiding rail 11 can be adjusted. Even further, a fixing hole 224 is also provided on the installation portion 222 corresponding to the upper door rail 1, and the upper door rail 1 is provided with a fixing position corresponding to the fixing hole 224. By inserting a fixing member through the fixing hole 224 and the fixing position, the damper 21 is fixed on the upper door rail 1. Optionally, the cover plate 22 is provided with a disassembly groove 220 to disassemble the damper 21 from the installation opening 10 by applying an upward force to the disassembly groove 220.
[0042] In practice, the trigger member 31 is disposed above the guide wheel 32. On the one hand, it is more convenient for the disassembly and installation of the damper 21. On the other hand, it also makes the structure for fixing the damper 21 in the guide track 11 simpler. Preferably, the trigger structure of the damper 21 is disposed on one side in the horizontal direction of the trigger member 31, which is convenient for the trigger member 31 to slide along the guide track 11 to the damper 21 to trigger the structure, and is also convenient for the damper 21 to be arranged along the extending direction of the guide track 11, simplifies the installation structure, and also enables the thickness of the upper door rail 1 to be designed thinner. More preferably, the structure of the trigger member 31 is a cylindrical structure with a diameter slightly smaller than that of the guide wheel 32, so that the trigger member 31 has a larger volume. Thus, when the guide wheel 32 cooperates with the guide track 11, the trigger member 31 will not contact the guide track 11, and further it is more convenient for the trigger member 31 to trigger the damper 21. Even if the trigger member 31 contacts the guide track 11, because the circumferential side of the trigger member 31 is an arc surface, rolling contact will be formed, avoiding the increase of friction force and affecting the sliding. Even more preferably, the trigger member 31 and the guide wheel 32 are coaxially arranged, ensuring the synchronism when the trigger member 31 and the guide wheel 32 slide, saving more occupied space, and being simpler in structure. Optionally, the trigger member 31 and the pulley are sequentially stacked on the upper side of the side sliding door body 3.
[0043] Wherein, the trigger structure includes a hook 212 and a limiting platform 213. A buckling space 214 is reserved between the hook 212 and the limiting platform 213. The limiting platform 213 is damping-connected to the damper 21. The buckling space 214 is used to cooperate with the trigger member 31. In practical applications, two groups of upper door rails 1 are provided, and the two groups of upper door rails 1 are arranged perpendicular to each other to form an upper guide rail bracket. If one group of dampers 21 is provided, the damper 21 can be disposed in the guide track 11 of one of the two groups of upper door rails 1. In fact, two groups of dampers 21 are provided. One group of dampers 21 is detachably installed in the installation opening 10 of one group of upper door rails 1, and the other group of dampers 21 is detachably installed in the installation opening 10 of the other group of upper door rails 1. In fact, the hook 212 in one group of dampers 21 is arranged away from the hook 212 in the other group of dampers 21, and the limiting platform 213 in one group of dampers 21 is arranged close to the limiting platform 213 in the other group of dampers 21.
[0044] Specifically, trigger members 31 are disposed at both opposite ends on the upper side of the side sliding door body 3. Correspondingly, pulleys 32 can also be disposed at both opposite ends on the top surface of the side sliding door body 3. Preferably, two groups of pulleys 32 can be disposed at the other end of the two opposite ends on the top surface of the side sliding door body 3, so that both ends of the top surface of the side sliding door body 3 can be slidably connected to the two groups of door rails 1 respectively. More preferably, the two groups of pulleys 32 at this end of the top surface of the side sliding door body 3 are connected by a connecting frame 33, and the opposite ends of the connecting frame 33 are respectively rotatably connected to the pulleys 32.
[0045] In practice, when the side-sliding door body 3 is pushed to move along the upper door rail 1, the trigger member 31 slides along the guiding rail 11 to the catch hook 212, then slides along the catch hook 212 into the buckling space 214 and abuts against the limiting platform 213, so that the trigger member 31 is stably buckled in the buckling space 214. Under the action of inertia, the trigger member 31 pushes the limiting member 213 to push the damping of the damper 21, so that the damping of the damper 21 forms a reverse acting force on the trigger member 31, thereby eliminating the inertia of the trigger member 31 and achieving a buffering effect. Moreover, the trigger member 31 can be buckled or disengaged along the catch hook 212 and cannot cross the limiting platform 213, that is, the limiting platform 213 plays a role in restricting movement; since the catch hook 212 of one set of dampers 21 is arranged away from the catch hook 212 of the other set of dampers 21, and the limiting platform 213 of one set of dampers 21 is arranged close to the limiting platform 213 of the other set of dampers 21, as Figure 7 and Figure 8 shown, when the trigger member 31 at one end of the upper side of the side-sliding door body 3 is buckled in the buckling space 214 of one set of dampers 21, the trigger member 31 at the other end of the upper side of the side-sliding door body 3 is disengaged from the buckling space 214 of the other set of dampers 21 and slides from the opposite end of the other upper door rail 1 to the opposite end of the other upper door rail 1, as Figure 9 and Figure 10 shown, when the trigger member 31 at the other end of the upper side of the side-sliding door body 3 is buckled in the buckling space 214 of the other set of dampers 21, the trigger member 31 at one end of the upper side of the side-sliding door body 3 is disengaged from the buckling space 214 of one set of dampers 21 and slides back to the opposite end of one upper door rail 1 from the opposite end of one upper door rail 1.
[0046] It should be noted that each embodiment in this specification is described in a progressive manner. The key point of each embodiment is to illustrate the differences from other embodiments. The same and similar parts among the embodiments can be referred to each other. Although the optional embodiments of the embodiments of the present invention have been described, those skilled in the art can make additional changes and modifications to these embodiments once they know the basic creative concept. Therefore, the appended claims are intended to be construed as including the optional embodiments and all changes and modifications falling within the scope of the embodiments of the present invention.
[0047] Finally, it should also be noted that in this text, relational terms such as first and second are only used to distinguish one entity from another, and do not necessarily require or imply any actual relationship or order between these entities. Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, so that an article or terminal device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such article or terminal device.
