[0001] This utility model relates to an adaptive damping buffer closing device for a folding sliding door, belonging to the field of sliding door technology. Background Technology

[0002] Sliding door panels consist of a door frame (also known as an edging) and a door panel. Sliding door frames are classified into three types: aluminum alloy profile sliding door frames (hereinafter referred to as aluminum alloy sliding doors), stainless steel sliding door frames (hereinafter referred to as stainless steel sliding doors), and galvanized steel plate sliding door frames (hereinafter referred to as galvanized sliding doors, also known as simple doors).

[0003] Some sliding doors lack damping or have poor damping capabilities during use, and excessive force can easily damage the door. Therefore, an adaptive damping and buffering closing device for folding sliding doors is needed for people to use. Utility Model Content

[0004] The purpose of this utility model is to provide an adaptive damping buffer closing device for folding sliding doors. When used in conjunction with buffer clamps and buffer stops one and two, the buffer clamps can effectively pull the sliding door, reducing the probability of the sliding door rebounding when closing forcefully. At the same time, when used in conjunction with buffer support plates and buffer springs, it effectively avoids excessive impact of the sliding door on the door frame when moving the sliding door forcefully, further reducing the probability of the sliding door rebounding and resetting due to forceful movement, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An adaptive damping buffer closing device for a folding sliding door includes a mounting plate. The mounting plate has connecting mounting holes on its top inner side and left inner side. One side of the mounting plate rests on a buffer plate. A movable sliding plate is fixedly connected to the bottom end of the buffer plate, and a movable sliding plate is fixedly connected to the top end of the buffer plate. Movable grooves are formed on the top inner side and left inner side of the mounting plate, and limiting grooves are also formed on the top inner side and left inner side of the mounting plate. Limiting sliders are fixedly connected to one side of both movable sliding plates, and the limiting sliders are cylindrical in shape.

[0007] Furthermore, the limiting sliders are symmetrically arranged, and the limiting sliders are slidably connected to the mounting plate through limiting grooves.

[0008] Furthermore, the inner side of the mounting plate is provided with a buffer spring, and the two ends of the buffer spring are respectively fixedly connected to the bottom of the movable slide groove and the movable slide plate.

[0009] Furthermore, a fixed connecting rod is spirally connected to one side of the movable sliding plate, and a fixed mounting component is rotatably connected to the other end of the fixed connecting rod. A buffer clamp is fixedly connected to one side of the fixed mounting component.

[0010] Furthermore, the buffer plate is U-shaped and is made of an elastic material.

[0011] Furthermore, a buffer stop bar is fixedly connected to the inner side of the buffer clamp in a symmetrical arrangement.

[0012] Furthermore, a second buffer stop bar, which is symmetrically arranged, is fixedly connected to the outer side of the buffer clamp.

[0013] The beneficial effects of this utility model are:

[0014] By incorporating buffer plates, buffer springs, buffer clamps, and buffer stops, this invention effectively pulls the sliding door in place when used with the buffer clamps in conjunction with buffer stops one and two. This reduces the likelihood of the sliding door rebounding when slammed shut. Furthermore, the use of buffer plates and buffer springs effectively prevents the sliding door from excessively impacting the door frame when moved forcefully, further reducing the chance of the sliding door rebounding and resetting due to forceful movement.

[0022] 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.

[0023] Example 1, please refer to Figures 1-5 This utility model provides a technical solution:

[0024] An adaptive damping buffer closing device for a folding sliding door includes a mounting plate 1. The mounting plate 1 has connecting mounting holes 2 on its top inner side and left inner side. One side of the mounting plate 1 is attached to a buffer plate 3. A movable sliding plate 4 is fixedly connected to the bottom end of the buffer plate 3, and a movable sliding plate 5 is fixedly connected to the top end of the buffer plate 3. Movable grooves 6 are provided on the top inner side and left inner side of the mounting plate 1, and limiting grooves 7 are provided on the top inner side and left inner side of the mounting plate 1. Limiting sliders 8 are fixedly connected to one side of both movable sliding plate 4 and movable sliding plate 5, and the limiting sliders 8 are cylindrical in shape.

[0025] As a preferred technical solution of this utility model, the limiting sliders 8 are symmetrically arranged, and the limiting sliders 8 are slidably connected to the mounting plate 1 through the limiting groove 7; thus preventing the movable slide from falling off when it slides.

[0026] As a preferred technical solution of this utility model, the inner side of the mounting plate 1 is provided with a buffer spring 9, and the two ends of the buffer spring 9 are respectively fixedly connected to the bottom of the movable slide 6 and the movable slide plate 4; the spring can effectively buffer and protect, and prevent the sliding door from hitting the door frame directly without any buffer.

[0027] Please refer to Example 2 Figure 4 The difference between this embodiment and Embodiment 1 is that:

[0028] As a preferred technical solution of this utility model, a fixed connecting rod 10 is spirally connected to one side of the movable sliding plate 2 5, and a fixed mounting part 11 is rotatably connected to the other end of the fixed connecting rod 10. A buffer clamp 12 is fixedly connected to one side of the fixed mounting part 11. The buffer clamp 12 is U-shaped and made of elastic material. A buffer stop bar 13 is fixedly connected to the inner side of the buffer clamp 12 and a buffer stop bar 2 14 is fixedly connected to the outer side of the buffer clamp 12. A limiting pin is installed at the top of the sliding door. When the sliding door is moved, the pin squeezes the buffer stop bar 13 into the buffer clamp 12. The clamp and the stop bar can prevent the sliding door from rebounding too much.

[0029] Working principle of this utility model:

[0030] When in use, a limit stop is installed at the top of the sliding door. When the sliding door is moved, the stop squeezes the buffer stop bar 13 into the buffer clamp 12, causing the buffer clamp 12 to rub against the inner wall of the movable slide groove 6 with the buffer stop bar 14, thus slowing down the movement speed of the sliding door. The clamp and the stop bar can prevent the sliding door from resetting, effectively preventing excessive rebound of the sliding door. Moreover, after the sliding door squeezes the buffer clamp 12, the clamp can push the movable slide plate 2 5 through the fixed connecting rod 10. The movable slide plate 2 5 moves one end of the buffer support plate 3, changing its tilt angle. The other end of the buffer support plate 3 will squeeze the buffer spring 9 through the movable slide plate 2 5, effectively avoiding excessive impact of the sliding door on the door frame when moving the sliding door with great force, and reducing the probability of the sliding door rebounding and resetting due to great force.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0032] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
