Description

Technical Field

[0001] This utility model relates to the technical field of sliding doors, and in particular to a buffer mounting structure and a sliding door. Background Technology

[0002] Buffers are common accessories in sliding doors, mainly used to cushion shocks and prevent the sliding door from being subjected to strong impacts.

[0003] Existing buffers are generally fixedly installed above the sliding door. The buffer moves into the guide rail when the sliding door is pushed or pulled, thus providing a buffering effect. If the buffer needs to be removed or replaced, the sliding door needs to be removed, which is inconvenient. Moreover, for some sliding door structures that use rollers and rails (the two ends of the rail are fixed to other fixed structures such as side door frames or walls, and the rollers are installed on the door panel. During the movement of the sliding door, the rollers slide against the upper side of the rail), it is difficult to install the buffer on the upper side of the sliding door. In this case, the buffer needs to be installed in the rail.

[0004] However, existing buffer installation structures involve first fixing the buffer in the hanging rail, and then installing the hanging rail and the sliding door. When it is necessary to disassemble and replace the buffer, the rail and the sliding door must be disassembled to remove and install the buffer. The disassembly and installation of the buffer is inconvenient, increases maintenance costs, and repeated disassembly and installation of the sliding door and rail can easily damage the sliding door and rail. Utility Model Content

[0006] Another objective of this invention is to provide a sliding door that allows for the installation or removal of the buffer without disassembling the track or the sliding door itself. This solves the problem that existing buffer installation structures require the disassembly of the track and the sliding door to install or remove the buffer, making the installation and removal of the buffer inconvenient.

[0010] Optionally, the first operating port is a strip-shaped hole, and the first operating port extends along the length direction of the track body. The first operating port is open at one end facing the first opening so that the first operating port and the first opening are interconnected. The diameter of the upper end face of the bolt is greater than the inner diameter of the first operating port in the width direction.

[0011] Optionally, the buffer includes a buffer body and two connecting members, the two connecting members being detachably connected to both ends of the buffer body along its length; the upper end faces of the two connecting members are respectively provided with the first mounting holes.

[0012] Optionally, the connector includes a first connecting portion and a second connecting portion connected sequentially along the length direction of the buffer body; the first connecting portion is located on one side of the buffer body along its length direction, the second connecting portion is located on the upper side of the buffer body, one end of the second connecting portion is fixedly connected to the upper end of the first connecting portion, the other end of the second connecting portion extends along the length direction of the buffer body, and the second connecting portion is detachably connected to the buffer body; the first mounting hole is formed on the upper end face of the first connecting portion.

[0013] Optionally, the second connecting portion has a second operating port on its end face opposite to the first connecting portion.

[0014] Optionally, the first connecting part and the second connecting part are integrally formed structures.

[0015] Optionally, the lower end face of the track body is provided with a second opening corresponding to the first opening, and the length of the second opening is less than the length of the first opening.

Therefore, it is convenient and quick to install or remove the buffer without disassembling the hanging rail or the sliding door, solving the problem that existing buffer installation structures require disassembly of the rail and the sliding door to install or remove the buffer, making buffer disassembly and installation inconvenient.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0023] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a fixed connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal connection of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the word "and / or" throughout the text means including three parallel solutions; taking "A and / or B" as an example, it includes solution A, solution B, or a solution that simultaneously satisfies A and B. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0025] To resolve the above technical issues, please refer to [link / reference]. Figure 2 and Figure 3 This utility model proposes a buffer mounting structure, including a hanging rail 1 and a buffer component 2; The hanging rail 1 includes a rail body 11 and a mounting plate 12. The rail body 11 has a cavity 111 for mounting the buffer 2 inside. The upper end face of the rail body 11 has a first opening 112, and the first opening 112 is connected to the cavity 111. The mounting plate 12 is fixedly connected to the upper end of the track body 11, and the mounting plate 12 is located on both sides of the length direction of the first opening 112. After the buffer 2 is installed into the receiving cavity 111 through the first opening 112, both ends of the buffer 2 in the length direction are located on the lower side of the corresponding mounting plate 12, and the buffer 2 is detachably connected to the mounting plate 12 in the receiving cavity 111.

[0026] The buffer mounting structure described in this utility model is applied to a sliding door. Please refer to [link / reference]. Figure 1The movable door includes a fixed door 4, a movable door 5, and a roller structure 6. The roller structure 6 is fixedly connected to the movable door 5 and slidably connected to the track body 11. The buffer 2 works in conjunction with the roller structure 6 to buffer and dampen the movable door 5 when it moves (it should be noted that the working principle of the buffer 2 and the roller structure 6 is existing technology). When installing or removing the buffer 2, the movable door 5 must first be moved away to prevent interference between the buffer 2 and the roller structure 6 (to avoid the roller structure 6 blocking the position of the first opening 112, thus affecting the installation or removal of the buffer 2).

[0027] When installing the buffer 2, it can be tilted and inserted into the receiving cavity 111 through the first opening 112. After the buffer 2 is fully placed in the receiving cavity 111, its position can be adjusted by moving it left and right, so that both ends of the buffer 2 in the length direction are located on the lower side of the corresponding mounting plate 12. Then, the buffer 2 is fixedly installed to the mounting plate 12 (for example, it can be detachably connected by bolts 3, magnetic attraction, etc.). When disassembling, first disconnect the connection between the buffer 2 and the mounting plate 12, so that the buffer 2 can move left and right in the receiving cavity 111. Then, move the buffer 2 so that one end of the buffer 2 is moved to the first opening 112. Lift one end of the buffer 2 from the first opening 112 and pull it out obliquely upward in an inclined posture to complete the disassembly of the buffer 2.

[0028] This invention, by providing a first opening 112 and a receiving cavity 111 on the hanging rail 1, allows the buffer 2 to be directly inserted into the hanging rail 1 through the first opening 112. When disassembly is required, the buffer 2 can be moved left and right within the receiving cavity 111 to adjust its position, thereby lifting one end of the buffer 2 from the first opening 112 and pulling it out obliquely upwards. The mounting plate 12 facilitates detachable fixing to the buffer 2. When installing or disassembling the buffer 2, it is not necessary to remove the hanging rail 1 or the sliding door. Installation and disassembly are convenient and quick, solving the problem that existing buffer installation structures require the removal of the rail and the sliding door to install and disassemble the buffer, making buffer disassembly and installation inconvenient.

[0029] Please see Figure 4 and Figure 5 Furthermore, the upper end face of the mounting plate 12 is provided with a first operation port 121, which is connected to the receiving cavity 111. The buffer 2 has first mounting holes 21 at both ends along its length that mate with the corresponding first operating port 121. The buffer mounting structure also includes bolts 3, which are provided one-to-one with the first mounting holes 21; The lower end of the bolt 3 is threaded to the corresponding first mounting hole 21, the upper end of the bolt 3 extends into the receiving cavity 111, and at least a portion of the upper end face of the bolt 3 abuts against the lower end face of the mounting plate 12, so that the buffer 2 and the mounting plate 12 are fixed together.

[0030] More specifically, during installation, firstly, the bolt 3 is installed into the corresponding first mounting hole 21, and then the buffer 2 is installed into the receiving cavity 111 through the first opening 112. The position of the buffer 2 in the receiving cavity 111 is adjusted so that the bolt 3 is located below the corresponding first operating port 121. A tool for installing and removing the bolt 3 (such as a hex key for hex bolts, the specific tool to be selected according to the type of bolt 3) is inserted from the first operating port 121 into the receiving cavity 111 and the bolt 3 is adjusted until at least a portion of the upper end face of the bolt 3 is pressed against the lower end face of the mounting plate 12. The lower end of the bolt 3 must always be located in the first mounting hole 21. The buffer 2 is pressed against the receiving cavity 111, thereby completing the fixation between the buffer 2 and the mounting plate 12, that is, completing the fixed installation between the buffer 2 and the track body 11.

[0031] This invention adjusts the bolt 3 to abut against the lower end face of the mounting plate 12, thereby pressing the buffer 2 against the receiving cavity 111, thus fixing the buffer 2 to the mounting plate 12 (that is, completing the fixed installation between the buffer 2 and the track body 11). This prevents the bolt 3 from protruding from the upper end face of the mounting plate 12, avoiding affecting the movement of the hanging wheel on the hanging rail 1.

[0032] Please see Figure 4 and Figure 5 Furthermore, the first operating port 121 is a circular hole, and the first operating port 121 and the first opening 112 are spaced apart; the upper end face diameter of the bolt 3 is larger than the inner diameter of the first operating port 121.

[0033] By making the diameter of the upper end face of the bolt 3 larger than the inner diameter of the first operating port 121, the upper end face of the bolt 3 can be tightly abutted against the lower end face of the mounting plate 12. The size of the first operating port 121 on the mounting plate 12 does not need to be precisely matched with the size of the bolt 3; it is sufficient that the inner diameter of the first operating port 121 is smaller than the diameter of the upper end face of the bolt 3. This helps to improve the production efficiency of the lifting rail 1.

[0034] Specifically, the first operating port 121 can also be configured in other shapes, such as a rectangular or rhomboid cross-section, as long as it can ensure that at least a portion of the upper end face of the bolt 3 can be pressed against the lower end face of the mounting plate 12.

[0035] Please see Figure 6 and Figure 7 Furthermore, the first operating port 121 is a strip-shaped hole, and the first operating port 121 extends along the length direction of the track body 11. The first operating port 121 is open at one end facing the first opening 112 so that the first operating port 121 and the first opening 112 are interconnected. The diameter of the upper end face of the bolt 3 is greater than the inner diameter of the first operating port 121 in the width direction.

[0036] By setting the first operating port 121 as a strip-shaped hole extending along the length direction of the track body 11 and communicating with the first opening 112, when the buffer 2 is inserted into the receiving cavity 111, the installation position between the buffer 2 and the mounting plate 12 can be adjusted through the first operating port 121, thereby adjusting the installation position of the buffer 2 relative to the hanging rail 1.

[0037] By making the diameter of the upper end face of the bolt 3 larger than the inner diameter of the first operating port 121 in the width direction, at least a portion of the upper end face of the bolt 3 can be pressed against the lower end face of the mounting plate 12.

[0038] To further clarify, the track body 11 and the mounting plate 12 are integrally formed structures.

[0039] Please see Figures 3 to 4 Furthermore, the buffer 2 includes a buffer body 22 and two connecting members 23, which are detachably connected to both ends of the buffer body 22 along its length. The upper surfaces of the two connecting members 23 are respectively provided with the first mounting holes 21.

[0040] By detachably connecting the connector 23 to both ends of the buffer body 22 along its length, both the buffer body 22 and the connector 23 can be replaced individually, which helps to reduce the maintenance cost of the buffer 2.

[0041] Furthermore, by correspondingly opening the first mounting hole 21 on the upper end face of the connector 23, when the position or size of the buffer 2 does not match the first operating port 121, it is not necessary to replace the entire buffer 2; a suitable connector 23 can be directly replaced. For example, the positions of the first mounting holes 21 on different connectors 23 are different, which can accommodate the situation where the positions of the buffer 2 and the first operating port 121 do not match; or the sizes of the first mounting holes 21 on different connectors 23 are different, and the first mounting holes 21 of different sizes can match the bolts 3 of different sizes. The upper end face diameters of the bolts 3 of different sizes are different, thereby accommodating the situation where the size of the buffer 2 and the first operating port 121 does not match.

[0042] Please see Figures 3 to 4 Furthermore, the connector 23 includes a first connecting portion 231 and a second connecting portion 232 that are sequentially connected along the length direction of the buffer body 22; The first connecting part 231 is located on one side of the buffer body 22 along its length, and the second connecting part 232 is located on the upper side of the buffer body 22. One end of the second connecting part 232 is fixedly connected to the upper end of the first connecting part 231, and the other end of the second connecting part 232 extends toward the length of the buffer body 22. The second connecting part 232 is detachably connected to the buffer body 22. The first mounting hole 21 is formed on the upper end face of the first connecting part 231.

[0043] The first connecting part 231 facilitates the opening of the first mounting hole 21, while the second connecting part 232 is used to fix it to the buffer body 22.

[0044] Please see Figure 4To further explain, the upper end face of the second connecting part 232 is provided with a second mounting hole 2321, and the buffer body 22 is provided with a third mounting hole corresponding to the second mounting hole 2321. The second connecting part 232 and the buffer body 22 can be detachably fixedly connected by another bolt 3. Specifically, the bolt 3 is passed through the second mounting hole 2321 and the third mounting hole in sequence, and the bolt 3 is threadedly connected to the second connecting part 232 and the buffer body 22, thereby fixing the second connecting part 232 and the buffer body 22. Of course, the second connecting part 232 and the buffer body 22 can also be fixed by other detachable connection methods, such as by snap-fit ​​or magnetic fixation.

[0045] Please see Figure 4 To further explain, the second connecting part 232 has a second operating port 2322 on its end face opposite to the first connecting part 231.

[0046] The second operation port 2322 is opened on the end face of the second connection portion 232 that is away from the first connection portion 231. It can be understood that the second operation ports 2322 on the second connection portions 232 at both ends of the length direction of the buffer body 22 are arranged facing each other.

[0047] Since the buffer 2 is installed into the receiving cavity 111 from the first opening 112, the two first connecting parts 231 are respectively located on the lower side of the corresponding mounting plate 12. When the buffer 2 needs to be disassembled, the first connecting part 231 and the corresponding mounting plate 12 must be disassembled first. Then the buffer 2 needs to be moved so that at least one connecting part 23 is completely moved to the lower side of the first opening 112 so that the buffer 2 can be easily lifted. Therefore, by providing the second operating port 2322, during disassembly, the operator can easily insert an operating tool from the first opening 112 into the second operating port 2322 (the operating tool can be a hex key, screwdriver, or other tool that can be inserted into the second operating port 2322). Then, by using the operating tool, the corresponding connector 23 can be slightly lifted and moved, thereby moving the entire buffer 2. When the corresponding connector 23 is completely located under the first opening 112, the buffer 2 can be pulled out obliquely upward from the first opening 112 in an inclined posture, thus completing the disassembly of the buffer 2.

[0048] Please see Figure 4 Furthermore, the first connecting part 231 and the second connecting part 232 are integrally formed structures.

[0049] By setting the first connecting part 231 and the second connecting part 232 as an integrally formed structure, the structural strength of the connector 23 is improved.

[0050] Please see Figure 8 Furthermore, the lower end face of the track body 11 is provided with a second opening 113 corresponding to the first opening 112, and the length of the second opening 113 is less than the length of the first opening 112. The first opening 112, the second opening 113 and the receiving cavity 111 are interconnected. The buffer 2 includes a locking block 24, and the second opening 113 is used for the locking block 24 to pass through and to limit the movement path of the locking block 24.

[0051] Specifically, the buffer 2 can be a commercially available product, and the locking block 24 of the buffer 2 is connected to the lower side of the buffer body 22. Because the length of the second opening 113 is less than the length of the first opening 112, the buffer 2 can be completely placed into the receiving cavity 111 without falling out of the second opening 113.

[0052] To further explain, if the position of the locking block 24 of the commercially available buffer 2 is set on the side of the buffer 2, then the second opening 113 is opened on the side of the track body 11 corresponding to it. In this case, the side of the track body 11 also needs to be provided with an insertion channel for the locking block 24 to be inserted. The upper end of the insertion channel is open and communicates with the first opening 112, and the lower end of the insertion channel communicates with the second opening 113.

[0053] Please see Figure 1 and Figure 9 This utility model also proposes a movable door, including a fixed door 4, a movable door 5, a hanging wheel structure 6, and a buffer mounting structure as described in any one of the above. The fixed door 4 and the movable door 5 are arranged sequentially along the length of the hanging rail 1, and the fixed door 4 and the movable door 5 are respectively located on the front and rear sides of the hanging rail 1; The fixed door 4 is fixedly connected to the hanging rail 1, and the hanging wheel structure 6 is fixedly connected to the end face of the movable door 5 facing the hanging rail 1. The hanging wheel structure 6 is slidably connected to the hanging rail 1 in the left and right directions.

[0054] Please see Figure 9Furthermore, the hanging wheel structure 6 includes a pulley 61 and a locking member 62; the pulley 61 and the locking member 62 are respectively located on the upper and lower sides of the hanging rail 1; the pulley 61 is located on the upper side of the hanging rail 1 and is slidably connected to the hanging rail 1, and the locking member 62 is located on the lower side of the hanging rail 1 and is configured to cooperate with the buffer member 2. It should be noted that the buffer member 2 can be a commercially available product, and the working principle of the buffer member 2 is also existing technology. When the movable door 5 is moved, the locking member 62 cooperates with the locking block 24 of the buffer member 2 to realize the buffering function of the buffer member 2.

[0055] Furthermore, the buffer mounting structure includes two buffer components 2, which are respectively disposed on both sides of the track body 11 along its length. The track body 11 has a first opening 112 and a second opening 113 corresponding to each of the two buffer components 2. Each first opening 112 has a mounting plate 12 on both sides along its length; optionally, the two first openings 112 can share the same mounting plate 12. There are two hanging wheel structures 6, located on the left and right sides of the movable door 5, respectively, and each hanging wheel structure 6 cooperates with its corresponding buffer component 2.

[0056] The sliding door of this utility model, by setting the buffer installation structure, eliminates the need to disassemble the hanging rail 1 when installing or disassembling the buffer 2. The buffer 2 can be directly inserted into the hanging rail 1 through the first opening 112, and the buffer 2 can move left and right within the receiving cavity 111 to adjust its position, allowing it to be pulled out from the first opening 112. This facilitates the installation and disassembly of the buffer 2, making the process convenient and quick. It solves the problem of existing buffer installation structures requiring the disassembly of the rail and sliding door to achieve buffer assembly and disassembly, which is inconvenient.

[0057] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
