Description

The utility model relates to a drawer slide rail. The slide rail is composed of a fixed slide rail fixed on the side of furniture and a slide seat fixed on the rear ends of both sides of the drawer. Therefore, the fixed slide rail can be inclined at an angle during assembly, making it easier and more convenient to open the drawer. There is a chute at the end of the fixed slide rail, which can be used when the user pushes the drawer back to close. When positioning, let the pulleys on the sliding seat fall into the chute of the fixed slide rail to achieve the effect of closing and positioning. Since the sliding seat is assembled at the rear end of both sides of the drawer, it can be arranged on the upper edge and middle of the drawer as required Or the bottom edge, so it can provide better practicability and applicability; at the same time, because the drawer slide rail proposed by the utility model only cooperates with the fixed slide rail and the sliding seat, the materials used can be simplified, and the Achieve the effect of saving material cost.

From the perspective of the existing drawer slide rail structure, there are different structural designs depending on where it is installed on the side of the drawer. As shown in Figure 4, it is a schematic diagram of a slide rail structure assembled on the bottom edge of the drawer , which is to fix a sliding rail 81 with a slightly Z-shaped cross-section on the bottom edges of both sides of the drawer 80, and a fixed sliding rail 83 with a "ㄈ"-shaped cross-section on both sides of the furniture. A pulley 82 is pivotally set at the end of the rail 81, and a matching pulley 84 is pivotally set at the front end of the fixed slide rail 83. This kind of drawer slide rail structure can only be applicable to the bottom edge of the drawer 80, and cannot be applied to the bottom edge of the drawer 80. In the middle or upper edge, its scope of application is greatly limited, and a concave point 85 is provided at an appropriate position near the rear end of the sliding rail 81, which is set in conjunction with the pulley 84 on the fixed slide rail 83. When the drawer 80 is pulled out to the appropriate position, the user will be notified that the drawer 80 has been pulled to the fixed position because the concave point 85 touches the pulley 84 at the front end of the fixed slide rail 83. The drawer 80 is pulled out to the outside, which is obviously not good enough in design, and when this structure is assembled, since the sliding rail 81 covers the bottom edges of both sides of the drawer 80, it cannot cooperate with the linkage safety lock of the drawer 80, It is greatly limited in its efficacy.

As shown in FIG. 5, it is a slide rail structure assembled on the side of the drawer 90. The purpose of its setting is to cooperate with the linkage safety lock of the drawer 90. This structural assembly method can overcome the above-mentioned slide rail 81 cover. Closed on the bottom edge of the drawer 80 both sides, and the side of the drawer 90 can be provided with a longitudinal groove to assemble the linkage safety lock, so it will be more progressive than the slide rail structure shown in Figure 4; but by From the perspective of its structure, it is composed of two sliding rails 91 fixed on both sides of the drawer 90 with a C-shaped cross-section, and two fixed slide rails 95 with a C-shaped cross-section fixed on the furniture. At the end of the sliding rail 91, a pulley 93 is pivotally provided with a downwardly protruding extension piece 92, and a convex point 94 is provided above the position relative to the extension piece 92, and the front end of the fixed slide rail 95 is provided with an upwardly protruding The extension piece 96 is pivotally provided with a pulley 97, and a paddle 98 is arranged above the pulley 97 of the extension piece 96. When assembling, the pulley 93 on the sliding rail 91 is assembled on the fixed slide rail 95 with a C-shaped cross section. , and the pulley 97 on the fixed slide rail 95 is assembled in the sliding rail 91 with a C-shaped cross section, so that the drawer 90 can slide in and out. When the drawer is pulled to the outer positioning position, the sliding rail will The convex point 94 of 91 touches the plectrum 98 and is locked and positioned, thereby ensuring that the drawer 90 will not be easily pulled out, and the purpose of convenient use is achieved. All are C-shaped, so it is very difficult to manufacture, and there are quite a lot of materials used in it, so that its production cost cannot be reduced, causing the limitation of market competitiveness; moreover, when the drawer 90 is about to be taken out or assembled into the positioning When the assembly is used, the plectrum 98 must be moved by the assembler, and the plectrum 98 is hidden above the fixed slide rail 95, thus causing troubles in assembly and use; the extension piece 92 on the slide rail 91 and the fixed slide The extension piece 96 on the rail 95 extends up and down respectively, so that it can only be assembled in the middle of the drawer 90, but cannot be assembled in the upper and lower edges, otherwise it will inevitably be stuck on the opening side of the furniture, which limits the applicability of the overall structure .

From the above description, it can be known that the existing drawer slide rail structure is not perfect in design, because of the needs of consumers, high-end wooden furniture is equipped with drawer slide rails, but it is limited by the linkage safety. Due to the design of the lock, the above-mentioned slide rail structure installed on the bottom edge of the drawer cannot be widely used (currently, most of them are used in chests of drawers for storing clothes, but cannot be applied to the drawers of office furniture). Due to the inconvenience of assembly, the structure is often avoided by processing and assembling personnel, so that relevant personnel have no choice but to adopt the slide rail structure assembled in the middle of the drawer. Although its production cost is high, it is limited by the common Without a suitable design, the cost can only be passed on to consumers, which invisibly increases the price of furniture and increases the burden on users.

From another point of view, the existing drawer slide rails have a considerable height and cannot be applied to the design of a single-piece board. In many novel-designed furniture (such as TV cabinets, wine cabinets, etc.), often It is designed with a pull-out single-piece board (bottom, drawer door) structure, and the existing slide rail structure cannot be applied to the design of a single-piece board at all, so that the single-piece board structure cannot be assembled with slide rails, resulting in structural design. on the blind spot.

The primary purpose of this utility model is to provide a drawer slide rail, which can be easily assembled on the bottom edge, middle or upper edge of the drawer with a fixed slide rail in the shape of "ㄩ" in section and a sliding seat. , and can improve the overall applicability and practicality.

Another purpose of the present utility model is to provide a drawer slide rail. With the design of the lug at the end of the fixed slide rail, the fixed slide rail can be installed with an inclination at an appropriate angle, so that the drawer can be pulled out more easily. Smooth and convenient.

Another purpose of this utility model is: by means of the chute design at the end of the fixed slide rail, when the drawer is pushed into the positioning position, the pulley of the slide seat can fall into the chute of the fixed slide rail, providing suitable positioning effect.

Another purpose of this utility model is to provide an excellent blocking and positioning effect when the drawer is pulled out to the positioning position by the cooperation of the blocking piece on the sliding seat and the front blocking piece of the fixed slide rail. When you want to take out the drawer, you only need to lift up the drawer slightly, so that the two blocking pieces can be staggered from each other, so that the drawer can be taken out conveniently.

The drawer slide rail of the utility model, because its height has been reduced to the narrowest limit, can be conveniently used in conjunction with various single-piece board designs, which overcomes the inapplicability of the existing slide rail structure due to height restrictions Disadvantages in monolithic board construction.

The utility model proposes a drawer slide rail, which is composed of a fixed slide rail and a sliding seat, wherein:

There is a downward protruding piece at the end of the fixed slide rail, and there is also a chute at the end of the fixed slide rail. A spacer is assembled at the front end;

The sliding seat is L-shaped, and a pulley is pivoted on the long side of the sliding seat, and a blocking piece is bent and extended on the long side;

In this way, the fixed slide rails can be fixed on both sides of the furniture, and the slide seat can be fixedly assembled at the end of the drawer, so that the pulleys of the slide seat can roll in the fixed slide rails, and cooperate with pads for the slide of the drawer in the furniture , and the positioning is controlled by the cooperation between the block and the front block of the fixed slide rail.
