Description

TECHNICAL FIELD

[0001] The utility model relates to drawer slide rail technical field, concretely is a three section hidden slide rail with buffering function. BACKGROUND

[0002] The slide rail is also called guide rail, slide, which is fixed on the cabinet of furniture, and is used for the connection of the drawer or the cabinet plate of furniture. The slide rail is suitable for the connection of the drawer of furniture, such as cabinet, furniture, briefcase, bathroom cabinet and the like.

[0003] In actual operation, the force of the user to pull the drawer is often difficult to keep constant, and when the drawer is pulled with force, a large impact force will be generated between the drawer and the slide rail because many existing three section hidden slide rails do not have a buffering structure. The impact force is transmitted to the entire slide rail system in an instant during the pulling action. From the perspective of mechanical structure, the connection parts between the sections of the slide rail and the drawer will bear stress exceeding the designed load when bearing the impact force. Under the long-term stress environment, the track of the slide rail is prone to deformation, resulting in that the pulling process is no longer smooth and the phenomenon of jamming occurs. At the same time, the impact force will also damage the movable parts, such as rollers or sliding blocks, of the slide rail, accelerate the wear and tear thereof, and reduce the service life thereof.

Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skill in the art without making creative labor all belong to the range of protection of the utility model.

[0030] Please refer to Figures 1-7The utility model provides a three -section hidden slide rail with buffer function, including first slide rail 1, second slide rail 2 and third slide rail 3, one side of first slide rail 1 is connected with second slide rail 2, the outer surface of second slide rail 2 is connected with third slide rail 3, the inboard of second slide rail 2 is rotatably connected with sliding wheel 4, and the inboard of second slide rail 2 is installed with rubber block 5 near the front end, the tail end of second slide rail 2 is embedded with tail plate 6, the inside of tail plate 6 is connected with buffer rod 7, the outer surface of buffer rod 7 is sleeved with spring 8, and the front end of buffer rod 7 is threadedly connected with buffer block 9, the upper surface of second slide rail 2 is fixedly connected with baffle one 10 near the front end, the inside of third slide rail 3 is rotatably connected with buffer wheel 11, and the inner surface of third slide rail 3 is fixedly connected with baffle two 12 near the front end, the outer surface of baffle two 12 is installed with side block 13, the top of side block 13 is fixedly connected with column block 14, the inside of column block 14 is inserted into inverted L-shaped sheet 15, and inverted L-shaped sheet 15 is inserted into fixed block 16.

[0031] Specifically, a plurality of mounting holes are formed through one side of the first slide rail 1, and the rubber block 5 is connected to the inner side of the second slide rail 2 by screws. The plurality of mounting holes can be used to select appropriate mounting positions, so that the first slide rail 1 can be firmly fixed on the corresponding position of the furniture cabinet or the like by cooperating with the screws, ensuring that the entire slide rail system will not easily displace or shake during use, providing a stable basic support structure for smooth pulling of the drawer. During the pulling of the drawer, the contact between the rubber block 5 and the first slide rail 1 can absorb and buffer the impact force generated by uneven force or rapid pulling to a certain extent, which can reduce the mechanical stress between the sections of the slide rail and prevent the slide rail from deforming or being damaged. At the same time, the rubber material can effectively reduce the noise generated during pulling, providing a quieter user experience.

[0032] Specifically, a plurality of sliding wheels 4 are arranged at equal intervals on the inner side of the second slide rail 2, and a limiting stopper 17 is connected to the inner side of the first slide rail 1 near the tail end by screws. The design of the sliding wheels 4 can significantly reduce the friction between the second slide rail 2 and the first slide rail 1 during pulling; the rolling friction is much smaller than the sliding friction, which makes the pulling action more smooth and reduces the pulling force required by the user. The plurality of sliding wheels 4 are arranged at equal intervals, which can evenly distribute the load of the second slide rail 2 and avoid excessive pressure on a single point, thereby reducing wear and deformation.

[0034] Specifically, the inner side of the third slide rail 3 is connected with two slide bars 18 through screws, and the tail end of the third slide rail 3 is clamped into the cover 19. The advantage is that the inner side of the third slide rail 3 is connected with two slide bars 18 through screws, and the slide bars 18 contact the outer surface of the second slide rail 2 when the third slide rail 3 is pulled out, and slide along the outer surface of the second slide rail 2 during the pulling process, providing stable guiding and supporting effect, ensuring that the third slide rail 3 maintains linear motion during pulling, and the slide bars 18 are designed of low-friction materials (such as nylon or polytetrafluoroethylene, etc.), which can effectively reduce the friction during pulling, and the cover 19 is arranged to block the tail end of the third slide rail 3, which can effectively prevent foreign matters from entering the inside of the slide rail, enhance the safety of the slide rail, and improve the overall aesthetic appearance.

[0035] Specifically, a screw hole is formed in the upper surface of the third slide rail 3 near the tail end, and the fixed block 16 is installed on the lower surface of the drawer through screws. The advantage is that before installing the entire slide rail, the slide rail needs to be compared with the bottom of the drawer to determine the position, and then the fixed block 16 is installed using screws, and then the entire slide rail is lifted and installed on the inner side of the furniture, and then the bottom of the drawer is contacted to the upper surface of the third slide rail 3, and the insertion hole on the fixed block 16 is aligned with the inverted L-shaped sheet 15 and inserted, and then a screw hole formed in the upper surface of the third slide rail 3 is connected using a screw, so that the third slide rail 3 and the drawer are connected, and then the entire slide rail and the drawer are connected, facilitating installation.

[0036] In use, first, before installing the slide rail, the slide rail is aligned and determined position at the bottom of the drawer, then the fixed block 16 is installed by screw through the screw hole near the tail end of the upper surface of the third slide rail 3, then the whole slide rail is lifted and installed inside the furniture; then the bottom of the drawer is contacted with the upper surface of the third slide rail 3, the insertion hole on the fixed block 16 is aligned and inserted into the inverted L-shaped piece 15, then the third slide rail 3 is further connected and fixed by screw, so that the third slide rail 3 is connected with the drawer, thereby connecting the whole slide rail with the drawer; during the process of pulling out the drawer, the plurality of sliding wheels 4 inside the second slide rail 2 reduces the friction between the first slide rail 1, so that the pulling out is more smooth, and the load is uniformly distributed, when the second slide rail 2 is pulled to the limit position, the rubber block 5 contacts the limiting block 17 connected by screw inside the first slide rail 1 near the tail end, preventing slipping; at the same time, if the user pulls out the drawer quickly, the side block 13 moves when pulling the third slide rail 3, after contacting the buffer block 9, the buffer block 9 compresses the spring 8, the spring 8 stores elastic potential energy and exerts a counter force on the side block 13, absorbing the kinetic energy of the side block 13, playing a buffering effect, preventing the damage of the slide rail parts; in addition, the slide strip 18 inside the third slide rail 3 is contacted with the outer surface of the second slide rail 2 during pulling, providing stable guidance and support, ensuring linear motion, and because of the low friction material characteristics, the friction is reduced, and the cover 19 at the tail end of the third slide rail 3 can prevent foreign matter from entering, enhancing safety and aesthetics.

[0037] Although the embodiments of the present application have been shown and described, it is to be understood that for the purpose of the present application, the embodiments can be changed, modified, replaced and varied in many ways without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
