Description

Heavy Duty Automatic Return Buffer Slides

technical field

The utility model relates to cabinet equipment, which is a slide rail installed in the cabinet to provide support and pull for drawers in the cabinet, in particular to an innovative structural design which is suitable for heavy-duty drawers and has automatic return and buffering functions.

Background technique

Whether it is a home, a company, or a store, there are many cabinets for organizing and placing items, and general cabinets are equipped with drawers to facilitate pulling out for picking and placing items. Usually, both sides of the drawer are equipped with sliding doors. rails for pulling out drawers lightly and effortlessly, but the slide rails set on both sides are only suitable for light-load drawers, and not suitable for heavy-load drawers. They are generally used for heavy-load slide rails. At the bottom of the drawer, the best loading position provides heavy loads, and the slide rails with large bottom space can also be designed to be thicker and stronger.

Designed for heavy-duty slide rails. The items placed in the drawer are heavy, and greater force must be exerted to open and close the drawer. When used to open the drawer, the person who pulls the drawer can also focus on the cabinet It assists in opening the drawer, but when the drawer is pushed back, it can only be pushed back by the weight of the person pushing the drawer back. It is not easy for light-weight people to push the drawer back completely, so there is a design that can automatically pull the drawer back , as shown in Figures 11 and 12, a swing block 82 is provided inside the outer rod 80 of the slide rail, the swing block 82 has a rotation axis 83, and a fastening groove 84 is provided above the eccentricity and a stopper 85 is used to limit the position In addition, the swinging block 82 is pulled by a spring 86, the outer rod 80 of the slide rail is provided with an inner rod 90 of the slide rail, and the inner rod 90 of the slide rail is provided with a hook 91 to cooperate with the use of the fastening groove 84, When the drawer and the inner rod 90 of the slide rail are pulled out, the fastening groove 84 of the swinging block 82 is toward the drawer opening direction, and the spring 86 is twisted by the swinging block 82 to present a stretched state. When the drawer is pushed back, the hook 91 touches the fastening groove 84 of the swinging block 82, so that the swinging block 82 is deflected at an angle, so that the spring 86 can instantly pull the swinging block 82 back, and the inner rod 90 of the slide rail is hooked by the fastening groove 84. 91 automatically pulls back, the design of this structure, its automatic return distance is limited to the distance that the spring 86 is stretched, the automatic return distance is short, and the sound issued when the spring 86 and the swing block 82 moves is loud, used for It is easy to wake up the sleeping person when the wardrobe in the bedroom is installed.

Utility model content

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.

An embodiment of the heavy-duty automatic return buffer slide rail of the present utility model is shown in Fig. 1, Fig. 2 and Fig. 3, including:

An outer slide rail 10, the outer slide rail 10 is provided with a bottom 11 and two sides 12 to match the length, and an opening 13 is set in the direction corresponding to the bottom 11 between the two sides 12;

Two sliding groups 2, the two sliding groups 2 are respectively combined with the two sides 12 in the outer slide rail 10, including an outer plate 20 and an inner plate 30;

The outer plate 20 is fixed to the two sides 12 of the outer slide rail 10 respectively;

The inner panel 30 is arranged on the inner side of the outer panel 20, and the inner panel 30 can be slid and displaced by the outer panel 20;

An inner slide rail 40, the inner slide rail 40 has an opening 41 facing the bottom 11 of the outer slide rail 10, and the two sides of the opening 41 are respectively provided with a side 42, and a top 43 is provided corresponding to the direction of the opening 41, A hook 44 is also provided in the top 43, and the inner sliding rail 40 is connected between the two inner plates 30 of the two sliding groups 2 with two sides;

A limit rail 50, the limit rail 50 is provided with a chute 51, and a sink hole 52 is arranged below the outer end of the chute 51, the limit rail 50 is combined with the bottom of the outer slide rail 10 11, and at the opening 41 of the inner slide rail 40;

A brake piece 60, one end of the brake piece 60 is provided with a pivot portion 61, and a fastening hole 62 is provided above, and the brake piece 60 is provided with two rollers 63, and the brake piece 60 is set at the limit on the rail 50, and move in the chute 51 with the two rollers 63, the fastening hole 62 is used for the positioning of the hook 44; and

A pressure cylinder 70, the pressure cylinder 70 has a normally protruding rod body 71, and the end of the rod body 71 is provided with a pivot portion 72, the pressure cylinder 70 is pivotally connected to the bottom 11 of the outer slide rail 10 at the position limit The direction of the sink hole 52 of the rail 50 is combined with the brake member 60 by the pivot joints 61, 72, and the pressure cylinder 70 is hydraulic or pneumatic.

An embodiment is shown in Figure 4, the outer slide rail 10 is combined on a cabinet A, usually the inner bottom of the cabinet A, and the inner slide rail 40 is combined with a drawer B, when the drawer B is opened and closed Then the slide group 2, the inner slide rail 40, the brake member 60 and the pressure cylinder 70 are linked; the opening of the inner slide rail 40, as shown in Fig. 5, Fig. 6, Fig. 7 and Fig. 8, the The hook 44 is in the fastening hole 62 , so the pulling of the inner slide rail 40 will synchronously drive the braking member 60 , so that the braking member 60 moves along the chute 51 and simultaneously compresses the rod body of the pressure cylinder 70 71, at this time, the inner slide rail 40 first moves out along the inner plate 30 of the sliding group 2, and when the brake member 60 moves to the outer end of the chute 51, the roller 63 will sink into the sink hole 52 , the pressure cylinder 70 changes with an angular offset, and the angular offset and the sink hole 52 are compressed and the rod body 71 is restricted. The brake member 60 will tilt, and the fastening hole 62 will be tilted towards the moving direction, so that the hook 44 of the inner slide rail 40 will be disengaged, so that the inner slide rail 40 can continue to be pulled outward, and the inner slide rail 40 will be pulled outward. The outward pull of 40 can utilize the cooperation of outer plate 20 and inner plate 30 to extend the length that the inner slide rail 40 is pulled out; when the inner slide rail 40 is closed, as shown in Figures 9 and 10, the user applies force to the The inner slide rail 40 is pushed back along the sliding group 2 until the hook 44 touches the clamping hole 62 in a tilted shape, and a thrust can be applied to the clamping hole 62 to make the roller 63 break away from the sinking At the same time, the brake member 60 is back to the right, and the hook 44 is buckled in the fastening hole 62 again, and the pressure cylinder 70 and the rod body 71 that were originally compressed lose their restrictive conditions, and the rod body 71 The force originally stored in pressure is released, so that the brake member 60 and the inner slide rail 40 are pushed back to the innermost position, so as to obtain movement return buffer and close the drawer B.

The sliding group 2 can include an outer plate 20 and an inner plate 30 for the sliding displacement of the inner slide rail 40 with a longer stroke, or only the outer plate 20 can be provided, and the inner slide rail 40 can directly cooperate with the outer plate 20 to slide shift.

In the above embodiment, the automatic return stroke of the heavy-duty automatic return buffer slide rail of the present invention depends on the length of the rod body 71 of the pressure cylinder 70, and the length of the rod body 71 can be used close to half the length of the outer slide rail 10, so it has The advantage of the long automatic return stroke is that the stroke is shorter simply by manually pushing it, which makes the use lighter and labor-saving.

The heavy-duty automatic return buffer slide rail of the present utility model is based on the pressure cylinder 70 and its principle to gradually release the pressure. Drawer B has the advantage of returning to its original position, and it is quiet from the action process to the completion of the action, which can avoid disturbing other people who are sleeping.
