[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] Reference Figures 1 to 6According to the first embodiment of the utility model, the slide rail assembly includes a slide rail member 100, a slider 200, a connecting rod 300, a buffer 400 and a positioning spring 500. The two ends of the slide rail member 100 are respectively a door opening end 110 and a door closing end 120. The slider 200 is slidably connected to the slide rail member 100. One end of the connecting rod 300 is pivotally connected to the slider 200, and the other end is rotatable with a fixed rotation point of the door body or a fixed rotation point of the door frame or a fixed rotation point of the door closer on the door body or a fixed rotation point of the door closer on the door frame. The buffer 400 is arranged on the slide rail member 100 and is arranged near the door opening end 110. The positioning spring piece 500 is arranged on the slide rail member 100. The positioning spring piece 500 has a buffer positioning portion 510. The buffer positioning portion 510 is located on the side of the buffer 400 near the door closing end 120, and the buffer positioning portion 510 can cooperate with the slider 200 to buffer the slider 200 and can limit the slider 200 between the buffer positioning portion 510 and the buffer 400. The buffer 400 can buffer the slider 200. The slide rail member 100 can be set on the door frame or the wall, and the connecting rod 300 is pivotally connected to the door body. When the door body is opened or closed, the connecting rod 300 and the slider 200 can be linked to make the slider 200 slide in the slide rail member 100. When the door is opened, the slider 200 slides toward the door opening end 110. When the door is about to be opened, the slider 200 can cooperate with the buffer positioning part 510 to perform preliminary buffering on the door body, and then the slider 200 slides to between the buffer positioning part 510 and the buffer 400 for positioning. When the door opening force is large, the slider 200 can cooperate with the buffer 400, and the buffer 400 can further buffer the door body to achieve the door opening buffer positioning. The structure is simple and the manufacturing cost is low.

[0033] Specifically, the slide rail member 100 can be installed on the door frame, and one end of the connecting rod 300 can be pivotally connected to the fixed rotating shaft of the door body, or pivotally connected to the door closer on the door body. When the door body is opened or closed, the other end of the connecting rod 300 can drive the slider 200 to slide along the length direction of the slide rail member 100. When closing the door, the slider 200 can slide toward the door closing end 120, and when opening the door, the slider 200 can slide toward the door opening end 110. The buffer 400 can be arranged on the slide rail member 100 and arranged close to the door opening end 110. The specific structure of the buffer 400 is not limited. The positioning spring piece 500 is also arranged on the slide rail member 100. The positioning spring piece 500 is elastic and can be made of a steel sheet or the like. The positioning spring piece 500 has a raised positioning buffer portion. The specific structure of the positioning buffer portion is not limited. There is a spacing between the positioning buffer portion and the buffer 400. When opening the door, the slider 200 synchronously slides toward the door opening end 110, and the door is about to be opened to the maximum When the door is opened, the slider 200 will first cooperate with the positioning buffer part. After the positioning spring piece 500 is deformed and buffered, the slider 200 slides to the above-mentioned spacing. At this time, the positioning buffer part can be reset under the elastic force, and provide a certain limiting force to the slider 200 to limit the slider 200 from retreating, so that the door body can be positioned to avoid automatic closing. The buffer 400 can limit the further opening of the door body on the one hand, and can further buffer the slider 200 on the other hand to protect related components. Especially when the door opening force is large, the positioning buffer part is not enough to buffer the door body, and the buffer 400 can provide buffering. Since the positioning spring piece 500 has a short lifespan, its elastic buffering performance is easy to decline, while the buffer 400 is stable in use and can provide stable buffering. In addition, the cost of the buffer 400 is low. Through the above-mentioned structure, the door opening can be stably buffered at a low cost, and related components can be protected to increase the service life.

[0034] It is understandable that the slide rail member 100 can also be set on the door body, and the other end of the connecting rod 300 can be pivoted to the fixed shaft of the door frame, or connected to the door closer on the door frame, so as to achieve a buffering effect. The specific installation method can be set according to needs.

[0035] Reference Figures 1 to 6 In some embodiments of the utility model, the buffer 400 includes a fixed seat 410, a buffer component and a sliding seat 430. The fixed seat 410 is arranged on the slide rail member 100. The sliding seat 430 is slidably arranged on the fixed seat 410, and the sliding seat 430 can slide along the length direction of the slide rail member 100. One end of the buffer component is connected to the sliding seat 430, and the other end is connected to the fixed seat 410.

[0036] Specifically, the fixed seat 410 can be fixedly connected to the slide rail member 100, and the sliding seat 430 can be slidably connected to the fixed seat 410, and the sliding seat 430 is located in the slide rail member 100, and its sliding direction is the length direction of the slide rail member 100. The specific sliding connection structure is not described in detail herein. A buffer component can be provided between the sliding seat 430 and the fixed seat 410, and one end of the buffer component is connected to the fixed seat 410, and the other end is connected to the sliding seat 430. The buffer component can buffer the slider 200 and the fixed member, and then can buffer the door body and the outside, so as to provide protection to reduce the occurrence of damage to related components, and the specific structure of the buffer component is not limited, and it is sufficient to be able to buffer. The above-mentioned arrangement structure is simple, the manufacturing cost is low, and the setting cost can be reduced.

[0037] Reference Figures 1 to 6 In some embodiments of the present invention, the buffer component includes a spring component 421 or a damper 422. Specifically, the buffer component can be set as a spring component 421, and the spring component 421 is a coil spring, one end of which can abut against the sliding seat 430, and the other end can abut against the fixed seat 410. It can be understood that the sliding seat 430 and the fixed seat 410 can be provided with corresponding grooves to facilitate the positioning and installation of the spring component 421.

[0038] It should be noted that the buffer component is not limited to the above-mentioned embodiments, and other embodiments may also be adopted. For example, the buffer component may also be a damper 422. The specific structure of the damper 422 is not described in detail. The fixed end of the damper 422 can be connected to the fixed seat 410, and the movable end can be connected to the sliding seat 430. The damper 422 can be used to slide the slider 200 and the fixed seat 410. The structure is simple, the manufacturing cost is low, and the cost of use can be reduced.

[0039] Reference Figures 3 to 6 In some embodiments of the present invention, an elastic buffer pad 431 is provided on the side of the sliding seat 430 away from the fixing seat 410 to further buffer the slider 200 .

[0040] Specifically, the elastic buffer pad 431 can be configured to be a colloid material, which can further absorb the impact and further buffer the slider 200 .

[0041] Reference Figures 1 to 4 In some embodiments of the present invention, the fixed seat 410 is provided with a sliding column 411 extending along the length direction of the slide rail 100, and the sliding seat 430 can be slidably connected with the sliding column 411. This can make the slider 200 slide more stably.

[0042] Specifically, a sliding post 411 may be protruded from the end of the fixing seat 410, and the slider 200 may be correspondingly provided with a through hole, and the sliding post 411 may be inserted into the through hole, so that the slider 200 can slide in cooperation with the sliding post 411. The slider 200 can slide stably, and its shaking can be reduced, so that the buffer 400 can provide stable buffering.

[0043] Reference Figures 3 to 6 In some embodiments of the present invention, the positioning spring piece 500 includes a connecting section 520, a positioning section 511 and a buffer section 512. The connecting section 520 is extended along the length direction of the slide rail 100. One end of the positioning section 511 is connected to one end of the connecting section 520 away from the door end 110. The other end of the positioning section 511 is connected to one end of the buffer section 512. The end of the positioning section 511 away from the door end 110 is tilted toward the opening of the slide rail 100. The end of the buffer section 512 close to the door opening end 110 is tilted toward the opening of the slide rail 100. The buffer section 512 and the positioning section 511 form a buffer positioning portion 510. The structure of the positioning spring piece 500 can achieve preliminary buffering and positioning of the door body.

[0044] Specifically, the positioning spring piece 500 can be integrally stamped, and the connecting section 520, the positioning section 511 and the buffer section 512 are arranged in sequence. The connecting section 520 is arranged parallel to the slide rail member 100, and the buffer section 512 and the positioning section 511 can form a protrusion to form a positioning buffer portion. The slider 200 can cooperate with the buffer portion, and the buffer portion drives the positioning spring piece 500 to deform to buffer the slider 200. After the slider 200 slides through the positioning section 511, the positioning spring piece 500 can gradually reset, and then the positioning section 511 can limit the slider 200 from retreating. It can be understood that under a certain force, the slider 200 can drive the positioning spring piece 500 to deform when retreating toward the door closing end 120, so that the slider 200 can break away from the restriction of the positioning section 511 so that the door body can be closed. Through the structure of the positioning spring piece 500, the preliminary buffering and positioning of the door body can be achieved.

[0045] Reference Figures 5 and 6 In some embodiments of the present invention, the angle between the buffer section 512 and the bottom wall of the slide rail member 100 is smaller than the angle between the positioning section 511 and the bottom wall of the slide rail member 100. Specifically, the slope of the buffer section 512 is set to be smaller, so that the positioning spring 500 is deformed, so that the slider 200 can slide to the positioning section 511 easily, and the slope of the positioning section 511 is set to be larger, so that the resistance of the slider 200 when retreating is larger, so as to provide a certain positioning resistance, so as to limit the closing of the door body.

[0046] Reference Figures 3 to 6In some embodiments of the present invention, the positioning spring piece 500 further includes a hook portion 521, which is disposed at one end of the connecting section 520 close to the door opening end 110, and the hook portion 521 is extended toward the opening direction of the slide rail member 100, and the hook portion 521 can abut against the side wall of the buffer 400 close to the door opening end 110 to limit the positioning spring piece 500 from sliding toward the door closing end 120. Specifically, the hook portion 521 can cooperate with the buffer 400, so that when the positioning spring piece 500 is used to position and limit the door body, the positioning spring piece 500 will not slip off, thereby improving its use stability.

[0047] Reference Figures 5 and 6 In some embodiments of the utility model, the buffer 400 includes a fixed seat 410, which is slidably connected to the slide rail member 100, and the fixed seat 410 is provided with a connecting hole 412 which is arranged through the bottom wall of the slide rail member 100. The fixed seat 410 can be connected to the slide rail member 100 through the connecting hole 412 by a fastener, and the positioning spring 500 can be pressed against the slide rail member 100. Specifically, the buffer 400 can be provided with a fixing seat 410 for being fixedly connected to the slide rail member 100. The fixing seat 410 can be set to a shape matching the slide rail member 100, so that the fixing seat 410 can slide along the slide rail member 100 without being separated from the slide rail member 100, so that the buffer 400 can slide and adjust its position to meet the needs of user use, and the fixing seat 410 can be provided with a connecting hole 412, and the connecting hole 412 penetrates toward the bottom wall of the slide rail member 100. The positioning spring piece 500 can be set close to the bottom wall of the slide rail member 100 and extend to the end of the buffer 400 through the connecting section 520 so that the hook portion 521 can hook the column buffer 400. The fastener can be a screw, and the screw can be threadedly connected to the connecting hole 412. When the screw is tightened, the screw can press the positioning spring piece 500 against the bottom wall of the slide rail member 100, and at the same time, the fixing seat 410 can be fastened to the slide rail member 100 to synchronously realize the fastening connection between the fixing seat 410 and the positioning spring piece 500.

[0048] Reference Figures 5 and 6 In some embodiments of the present invention, a side of the slider 200 close to the positioning spring sheet 500 is provided with an avoidance groove 210, and a raised matching portion 220 is provided on the bottom wall of the avoidance groove 210, and the matching portion 220 can match with the buffer positioning portion 510. Specifically, the slider 200 is provided with a corresponding avoidance groove 210 so that the positioning spring sheet 500 has enough avoidance space so that the slider 200 can slide, and the raised matching portion 220 can match with the positioning spring sheet 500 to achieve the corresponding positioning buffer function.
