Description

Technical Field

[0001] The present invention relates to the technical field of drawer slides, and particularly to a silent drawer slide structure. Background Art

[0002] A drawer slide, also known as a guide rail or a slideway, is a hardware connecting component fixed on a furniture cabinet body for the drawer or cabinet board of the furniture to move in and out; it determines whether the furniture drawer can be pushed and pulled smoothly and freely, and whether the drawer is durable.

[0003] Among drawer slides, the steel ball slide is a relatively commonly used one, which can also be called a full-extension steel ball slide. It is usually a two-section or three-section metal slide, and the more common structure is installed on the side of the drawer. A good-quality steel ball slide can ensure smooth pushing and pulling, large load-bearing capacity, and has functions of buffered closing or push-to-rebound opening. In addition, among the existing technical solutions of drawer slides, there are also commonly used types such as roller slides, gear slides, and damping slides.

[0004] For example, Chinese Patent CN106341968B discloses a slide rail assembly, which includes an outer slide rail, a middle slide rail, and an inner slide rail. The first tab of the outer slide rail is provided with a first unlocking edge, a first stop edge, and a second stop edge. The middle slide rail is provided with a chute for slidably mounting a positioning block up and down. The positioning block has a first stop end and a second stop end. The second tab of the inner slide rail is provided with a first unlocking portion, a first stop portion, and a second stop portion; the first stop end of the positioning block can be controlled to be blocked between the first stop edge and the second stop edge of the outer slide rail, and the second stop end can be controlled to be blocked between the first stop portion and the second stop portion of the inner slide rail, and has a front-back movement gap and an up-down displacement stroke, so that the middle slide rail and the inner slide rail can be sequentially retracted or pulled out of the outer slide rail. The slide rail assembly disclosed by this solution can slide and retract smoothly in sequence and can enhance the structural strength and durability.

[0005] However, the existing disclosed slide rail structures still have the technical problem of poor sound insulation performance. Specifically, for a slide rail structure applied to the movement in and out of drawers or cabinet boards of furniture, the simpler the structure, the easier it is to control the cost, and it is free from the trouble of frequent maintenance of complex structures. However, an overly simple drawer slide often means the lack of some functions, such as sound insulation, automatic ejection, etc. If a slide rail structure for drawers with good sound insulation performance is provided, it is an urgent technical problem to be solved currently. Summary of the Invention

[0006] Based on this, in view of the technical problem of how to improve the sound insulation performance of the slide rail structure, it is necessary to provide a silent drawer slide structure.

[0025] Please refer to Figures 1 to 2 , a silent drawer slide rail structure of the present invention includes: a guide rail structure 1, a sliding part 2, a sliding hinge part 3, a swing rod structure 4, a swing rod connecting seat 5 and a damper 6; the sliding part 2 is movably connected in the guide rail structure 1, the sliding hinge part 3 is disposed on the side of the sliding part 2, the sliding hinge part 3 is movably connected to the swing rod structure 4, the lower end of the swing rod structure 4 is hinged to the swing rod connecting seat 5, and the damper 6 is connected to the side of the swing rod structure 4.

[0026] Specifically, when the silent drawer slide rail structure of the present invention is in the working process, the rail structure 1 is fixedly arranged on the wall surface of an external cabinet or other structures, and the sliding part 2 is movably sleeved in the rail structure 1. Moreover, the sliding part 2 is connected to the side surface of an external drawer structure. Thus, when the user pulls out or pushes in the drawer structure from the cabinet, the sliding part 2 can be linked with the drawer. Therefore, when the drawer structure moves, it can drive the sliding part to slide back and forth in the rail structure 1. A sufficient amount of lubricating oil can be pre-applied at the sleeved position between the rail structure 1 and the sliding part 2 to reduce the friction between the two and minimize the noise during sliding. In addition, when the sliding part 2 moves, it can simultaneously drive the sliding hinge part 3, and the sliding hinge part 3 is movably connected to the swing rod structure 4. Thus, it can drive the swing rod structure 4 to swing back and forth at its connection to the swing connection seat 5. When the swing rod structure 4 swings, the damper 6 can absorb the sudden impact force generated by it. Furthermore, it can prevent the sliding speed of the sliding part 2 from being too fast. Thus, it can buffer the sudden impact force when the external drawer structure is pulled out and pushed in to avoid the noise generated by the external drawer structure colliding with the cabinet. It can be seen that the silent drawer slide rail structure of the present invention improves the silent performance of the slide rail structure.

[0027] Furthermore, the rail structure 1 has a connecting frame 101, a stop part 102, and a rail 103. A stop part 102 is arranged on the side surface of each connecting frame 101, and the rail 103 is arranged between the two stop parts 102. The sliding part 2 is movably sleeved on the rail 103.

[0028] Furthermore, the sliding part 2 has a plurality of sliders 201 and a slider connecting part 202. Each slider 201 is correspondingly movably connected to a rail 103, the slider connecting part 202 connects each slider 201 respectively, and the sliding hinge part 3 is arranged on the side surface of the slider connecting part 202.

[0029] Furthermore, the sliding hinge part 3 has a connecting seat 301, a hinge column 302, and an end limiting part 303. The connecting seat 301 is arranged on the side surface of the slider connecting part 202. One end of the hinge column 302 is connected to the connecting seat 301. The hinge column 302 is movably connected to the swing rod structure 4. The end limiting part 303 is arranged at the other end of the hinge column 302 relative to the connecting seat 301, and the swing rod structure 4 is arranged between the end limiting part 303 and the connecting seat 301.

[0030] Further, the swing rod structure 4 has a swing rod main body 401, a hinge chute 402, and a swing rotating shaft 403; the hinge chute 402 is arranged in the swing rod main body 401, the hinge column 302 is movably arranged in the hinge chute 402, the swing rotating shaft 403 is arranged at one end of the swing rod main body 401, and the swing rotating shaft 403 is movably connected to the swing rod connecting seat 5.

[0031] Further, the damper 6 is provided with a damping connecting shaft 601, a telescopic rod 602, an oil cylinder main body 603, and an oil cylinder connecting seat 604; the damping connecting shaft 601 is connected to the side surface of the swing rod main body 401, one end of the telescopic rod 602 is hinged to the resistance connecting shaft 601, and the other end of the telescopic rod 602 is movably arranged in the oil cylinder main body 603; the lower end of the oil cylinder main body 603 is movably connected to the oil cylinder connecting seat 604.

[0032] Specifically, the connecting frame 101 can be connected to an external cabinet or the like. When the sliding part 2 moves along the guide rail 103, the two stop parts 102 can be respectively located at both ends of the guide rail 103, so as to mark the starting and ending points of the sliding part 2, thereby preventing the movement of the sliding part 2 from exceeding the guiding range of the guide rail 103.

[0033] When the sliding part 2 reciprocates along the guide rail 103, the hinge column 302 arranged on the side surface of the sliding part 2 can reciprocate in the hinge chute 402 arranged in the swing rod main body 401. Thus, the hinge column 302 can push the hinge chute 402 to drive the swing rod main body 401, so that the swing rotating shaft 403 arranged at its lower end can rotate in the swing rod connecting seat 5; thus, the swing rod main body 401 can be made to swing.

[0034] Further, when the swing rod main body 401 is pushed to swing, the damping connecting shaft 601 arranged on the side surface of the swing rod main body 401 can be linked with the telescopic rod 602. Thus, when the swing rod main body 401 moves, the telescopic rod 602 can absorb the swing of the swing rod main body 401 into the oil cylinder main body 603, and the oil cylinder main body 603 can absorb the thrust or pull force of the telescopic rod 602 to buffer the sudden impact force received, so that the swing rod main body 401 can swing with damping, making the reciprocating sliding of the sliding part 2 have a damping feeling.

[0035] Further, please continue to refer to Figure 3 For a specific embodiment of a silent drawer slide rail structure of the present invention, for example Figure 3As shown, a drawer portion 7 is provided on the side of the sliding portion 2, and the side of the drawer portion 7 is connected to the slider connection portion 202; Figure 3 Although not marked, it can be easily inferred that, for the sake of the stability of the drawer portion 7 during pulling and pushing, the sliding portion 2 and the guide rail structure 1 can be provided on both sides of the drawer portion 7; while the sliding hinge portion 3, the swing rod structure 4, the swing rod connection seat 5, and the damper 6 only need to be provided on one side of the drawer portion 7.

[0036] In summary, a silent drawer slide rail structure of the present invention is respectively provided with a guide rail structure 1, a sliding portion 2, a sliding hinge portion 3, a swing rod structure 4, a swing rod connection seat 5, and a damper 6; the sliding portion 2 is movably connected in the guide rail structure 1, the sliding hinge portion 3 is provided on the side of the sliding portion 2, the sliding hinge portion 3 is movably connected to the swing rod structure 4, the lower end portion of the swing rod structure 4 is hinged to the swing rod connection seat 5, and the damper 6 is connected to the side of the swing rod structure 4. The damper 6 can absorb the sudden impact force generated thereby, and further prevent the sliding speed of the sliding portion 2 from being too fast. Thus, it can buffer the sudden impact force of the external drawer structure during pulling out and pushing in, so as to avoid the noise generated by the external drawer structure colliding with the cabinet body. Therefore, a silent drawer slide rail structure of the present invention solves the technical problem of how to improve the silent performance of the slide rail structure.
