Description

A sliding rail drawer

technical field

The utility model relates to a drawer, in particular to a drawer with slide rails.

Background technique

When the drawers are used, most of them use slide rail drawers to ensure the smooth opening and closing of the drawers, which is convenient for use. When the drawer uses slide rails, the drawer is fixed on the slide rails, and the slide rails are installed on the box body to realize the functions of pulling out and retracting the drawers. At present, the commonly used slide rails mainly include two-section slide rails and three-section slide rails, which are installed in home kitchen cabinets, furniture, desks, and drawer-type home appliances. Among them, the two-section slide rail product cannot pull out the entire drawer, which has obvious shortcomings, while the three-section slide rail can effectively solve this problem, and can pull out the entire drawer as a whole, so it is more and more widely used. . Especially in high-end furniture and electrical products, three-section slide rails are used more to facilitate the storage of items.

The three-section slide rail structure mainly includes upper rail, middle rail and lower rail (also called inner rail, middle rail and outer rail respectively), and the contacting slide rails are connected by sliding friction or ball rolling friction. As CN03220248.2 discloses a "heavy-duty steel profile three-stage ball guide rail", which is made of inner rail, middle rail, outer rail and balls made of drawn steel profiles. The outer rail and the middle rail are nested. The cross-sectional shape of the middle rail and the outer rail is: at least the upper and lower cross-sectional shapes of the middle rail or the outer rail are arc-shaped, and there are two semi-arc-shaped upper and lower inner surfaces of the outer rail and the upper and lower outer surfaces of the middle rail. The slideway groove is provided with rolling balls in the slideway groove, and the curved surface shape of the cross section of the inner rail coincides with the cross section of the arc groove of the middle rail and is embedded in the middle rail. The support between the three sections of guide rails is only realized by several balls, so there are defects and deficiencies such as unsmooth push and pull, high friction noise and unstable operation. CN200820238494.7 discloses a three-section metal drawer slide rail, which includes metal side plates that can be connected with the drawer bottom plate, front panel and rear plate, movable rails and fixed rails that slide and cooperate with the metal side plates, and are arranged on the movable rails to block the metal The elastic clamping glue that slides out of the side plate, and more than two roller assemblies arranged on the movable rail; the movable rail cooperates with the fixed rail to slide through the roller assembly arranged on it, and the fixed rail is provided with anti-moving rails. The anti-falling blocks at both ends of the roller assembly. The above-mentioned three-section slide rails cannot be reset automatically, which is inconvenient in use.

Contents of the invention

Aiming at the deficiencies of the prior art, the utility model provides a slide rail drawer, which can realize stable operation and automatic reset function on the basis of ensuring accurate guidance and realizing the overall pull out of the drawer, and can be used for high-end kitchen cabinets and high-end furniture , high-end desks and related electrical products.

The slide rail type drawer structure of the utility model includes the following contents: the slide rail type drawer includes a drawer, a slide rail and a box body, each drawer uses two slide rails to connect with the box body, and the slide rail adopts three-section slide rails, and the three-section slide rails include an upper Rail, middle rail and bottom rail. The middle rail has two installation support planes, namely the upper installation support plane and the lower installation support plane. The upper rail is set on the upper installation support plane of the middle rail, and the bottom rail is set on the lower installation support plane. The upper rail rack and pulley frame is set at the lower part of the upper rail, and the bottom rail rack and pulley frame is installed at the upper part of the bottom rail. Gear transmission is adopted between the upper rail rack and pulley frame and the bottom rail rack and pulley frame; A damper is provided at the end of the bottom rail.

In the utility model, the box body is a conventional structure in the field, and generally consists of two side panels, a back panel and a cover panel. The drawer is generally a box structure with an open top formed by a front panel, a back panel, a bottom panel, a left panel and a right panel, such as a D-shaped drawer.

In the present utility model, the bottom rail of the three-section slide rail is connected to the bracket, and there is at least one bracket, usually two, and the bracket generally adopts the shape of an "L" bracket or a flat bracket; the cross section of the middle rail can be "匚" " shape, "work" shape and other shapes; the upper rail and the middle rail have a nested structure, and the middle rail and the bottom rail have a nested structure, that is, the upper rail has a structure that encloses the upper mounting support plane of the middle rail, and the bottom rail has an encased structure. The structure of the support plane is installed on the lower part of the middle rail; pulleys can be arranged around the rack and pulley frame; the slider moves back and forth in the guide groove of the damping frame. In the utility model, the reset device of the three-section slide rail can use a stretcher spring, etc., and one end of the stretcher spring is fixed at the buckle position of the slider (when the upper rail is pulled, the damping hook drives the slider to move so as to control the contraction of the spring) , the other end is fixed at the buckle position of the damping frame (the damping frame is fixed on the bottom rail); the damper can be a damper commonly used in this field, such as a hydraulic cylinder damper; the maximum tension between the upper rail and the middle rail A limit structure is set at the open position, and a limit structure is set between the bottom rail and the middle rail at the maximum open position. The above limit structure can be a corresponding protrusion and groove structure between the contact surfaces. In the utility model, the lengths of the three slide rails (upper rail, middle rail and bottom rail) can be equal or unequal. Generally speaking, the upper rail and the bottom rail can be designed to be relatively longer and the middle rail relatively shorter, such as the middle rail The length of the upper rail can be 50% to 100% of the length of the upper rail, and the length of the upper rail and the bottom rail are equal.

The utility model adopts three-section slide rails, which can pull out the entire drawer; by setting rack and pulley racks and pulleys between the slide rails, the slide rails can run freely, and the friction force is small, eliminating the sliding friction between the slide rails generates noise. By setting the limit structure and the reset device, the slide rail can be pulled out and fixed at a suitable position. After use, when the slide rail is separated from the limit structure, it can automatically return to the original position through the action of the reset device. By setting the damper, it can ensure that the sliding rail is reset smoothly, without hard collision, without generating noise, and prolonging the service life. The slide rail type drawer of the utility model can be widely used in the fields of high-grade family kitchen cabinets, furniture, office appliances and the like.
