Description

Technical Field

[0001] This utility model relates to the field of sliding door buffer technology, and in particular to a buffer structure with good connection stability. Background Technology

[0002] Existing technology, such as Chinese utility model patent document, publication number CN219197042U, discloses a quick-release pulley buffer, including a first pulley group, a second pulley group, and a buffer body. The maximum thickness of the buffer body is less than the width of the opening below the track. The buffer body is located between the first and second pulley groups. One end of the buffer body is detachably hooked to the first pulley group, and the buffer body is rotatably mounted relative to the first pulley group. The other end of the buffer body is detachably fastened to the second pulley group. This is achieved by detachably hooking one end of the buffer body to the first pulley group and detachably fastening the other end of the buffer body to the second pulley group.

[0003] In the existing technology, elastic snap-fit ​​pulley blocks are used to achieve quick connection. Although this solves the problem of installation efficiency, the connection stability is lacking and needs further improvement. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a buffer structure that facilitates the assembly of the roller assembly and provides good connection stability.

[0005] A buffer structure with good connection stability designed for this purpose includes a buffer body and a roller assembly. The roller assembly includes a mounting base and rollers rotatably connected to the mounting base. The buffer body is provided with a mating block, and locking teeth are arranged on the wall surface of the mating block. The mounting base is provided with a mating space for mating with the mating block. The wall surface of the mating space corresponding to the locking teeth is provided with a movable space, and a locking tooth plate is provided in the movable space.

[0006] The locking tooth plate can move between a first position and a second position relative to the movable space; when the locking tooth plate is in the first position, the locking tooth plate engages with the locking tooth groove; when the locking tooth plate is in the second position, the locking tooth plate and the locking tooth groove are separated from each other.

[0007] The mounting base is equipped with a drive mechanism for moving the locking toothed plate from a first position to a second position.

[0008] Preferably, the active space is provided with a through hole for the mounting base, and the driving component includes an extension post provided on the locking tooth plate, the extension post extending outward through the through hole;

[0009] An elastic element is provided between the locking tooth plate and the movable space.

[0010] Preferably, a handle is provided at the outward-facing end of the extension column.

[0011] Preferably, the extension column is detachably connected to a limiting member, which fits against the outer wall of the mounting base.

[0012] Preferably, the extension post is threadedly connected to the connecting hole, and the extension post is rotatably connected to the locking toothed plate.

[0013] Compared with existing technologies, this invention improves the stability of the connection between the insert block and the interlocking space by optimizing the insertion and engagement. Simultaneously, the locking tooth plate and locking tooth groove effectively constrain the insert block and the interlocking space, preventing separation and thus completing the connection assembly. This optimizes the assembly process while ensuring connection stability. Attached Figure Description

[0028] See Figures 1-6A buffer structure with good connection stability includes a buffer body 10 and a roller assembly 20. The roller assembly 20 includes a mounting base 210 and rollers 220 rotatably connected to the mounting base 210. The buffer body 10 is provided with a mating block 110, and locking teeth 120 are arranged on the wall surface of the mating block 110. The mounting base 210 is provided with a mating space 200 for mating with the mating block 110. A movable space 201 is provided on the wall surface of the mating space 200 corresponding to the locking teeth 120. A locking tooth plate 310 is provided in the movable space 201. The locking tooth plate 310 can move between a first position and a second position relative to the movable space 201. When the locking tooth plate 310 is in the first position, the locking tooth plate 310 engages with the locking teeth 120. When the locking tooth plate 310 is in the second position, the locking tooth plate 310 and the locking teeth 120 are separated. The mounting base 210 is provided with a driving member for driving the locking tooth plate 310 to move from the first position to the second position.

[0029] During assembly, the locking tooth plate 310 is first moved from the first position to the second position by the driving component. Then, the mounting base 210 and the buffer body 10 are inserted into each other so that the insertion block 110 is inserted into the insertion space 200. Then, the locking tooth plate 310 is moved from the second position to the first position by the driving component so that the locking tooth plate 310 engages with the locking tooth groove 120, thereby constraining the relative movement of the insertion block 110 and the insertion space 200.

[0030] See Figure 4 The movable space 201 is provided with a connecting hole 202 that passes through the mounting base 210. The driving component includes an extension post 320 disposed on the locking tooth plate 310, which extends outward through the connecting hole 202. An elastic element 350 is disposed between the locking tooth plate 310 and the movable space 201. The function of the elastic element 350 is to apply a force to the locking tooth plate 310, keeping the locking tooth plate 310 in a first position. The outwardly extending extension post 320 serves to move the locking tooth plate 310. When unlocking, disassembling, or assembling, it is necessary to move the locking tooth plate 310 from the first position to the second position, which is achieved by moving the extension post 320.

[0031] Example 1 of the movement of extension post 320 relative to connecting hole 202: extension post 320 is movably inserted into connecting hole 202. When extension post 320 is manually pulled, it can be moved relative to connecting hole 202.

[0032] Embodiment Two: The extension post 320 moves relative to the connecting hole 202. The extension post 320 is threadedly connected to the connecting hole 202, and the extension post 320 is rotatably connected to the locking tooth plate 310. In this embodiment, when it is necessary to control the movement of the locking tooth plate 310, the threaded extension post 320 is rotated in either the forward or reverse direction. As the extension post 320 rotates, it moves while rotating under the action of the threaded connection, thereby driving the locking tooth plate 310 to move.

[0033] See Figure 4 The extension column 320 is provided with a handle 330 at its outward-facing end. The function of the handle 330 is to facilitate the movement or rotation of the extension column 320.

[0034] See Figure 4 The extension post 320 is detachably connected to a limiting member 340, which fits against the outer wall of the mounting base 210. The limiting member 340 is a retaining ring or nut, which constrains the position of the extension post 320 and prevents the elastic element 350 from causing the extension post 320 to fall out of the connecting hole 202.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
