Description

The utility model relates to an improved structure of a drawer slide rail, in particular to a basic form which is easy to manufacture and has a special and original form.

Commonly used drawer slide rails include two sets of pull plates and vertical plates that can be fitted together, which are separately arranged on both sides of the drawer to facilitate the opening and closing of the drawer. Its structure is shown in Figure 5, including a vertical plate (7) and A tie plate (8), because the two groups are symmetrically designed, only one set is explained here, wherein the vertical plate (7) and the tie plate (8) are all cut and pressed from the same steel plate, and have a U-shaped cross section. The two ends are pressed into the shape of the joint part through multiple procedures, and the pulleys (6) are respectively combined to roll in the slide rail, so that the vertical plate (7) is fixed on the inner side of the table, and the pull plate (8) is set on the The outside of the drawer can be opened or closed smoothly. In this design, both the vertical plate and the pull plate must be cut and then repeatedly pressed and formed, that is, each individual component must be processed with the same repetitive action, which causes a lot of time wasted in manufacturing. In addition, because it is installed behind the drawer, it must have a certain supporting force to support the drawer, especially when the drawer is opened, when the pull plate and the vertical plate are separated to the farthest, only the joint that is embedded provides support, as shown in Figure 6 , the stress points are concentrated in two parts, A and B. Commonly used slide rails cannot effectively provide support. In order to achieve the international standard load, only thicker steel plates can be used as the base material to obtain sufficient support. This can only be implemented with thicker steel plates, which obviously increases the cost of the product, and relatively increases other costs, such as the increase in freight due to weight.

In view of this, the inventor of the present invention continuously improves the design, accumulates many years of manufacturing experience, and actively researches and transforms to provide a better product.

The main purpose of this utility model is to provide an improved structure of the drawer slide rail, which has a special double-embedded rail cross-section, which can generate sufficient supporting force.

Another purpose of this utility model is to provide a combined drawer slide rail, the rail part can be drawn and formed at one time, which is convenient for rapid and mass production, and the fitting part is independently produced, and can also be pressed and formed in large quantities, matching the ingenious shape , can be quickly combined with the track department, which helps to increase production and reduce costs, and has economic value.

The accompanying drawings are hereby attached, and the explanations are as follows:

Please refer to Figures 1 and 2 first, the drawer slide rail of the present utility model includes a vertical panel fitting part (1), a vertical panel track part (2), a drawer fitting part (3) and a drawer track part (4) , wherein the fitting part (1) of the vertical board is set as a plate, the front end can be combined with the pulley (5), and the end (11) is pressed into a double hook shape, that is, the upper and lower edges form a barb shape, and the vertical board track part (2) is designed With a double-arc joint edge, an embedded groove (21) is set in the groove, which is just matched with the shape of the end of the vertical board joint part (1), and its upper and lower sides respectively extend out an arc-shaped clamp edge (22), which will After the end (11) of the vertical board fitting part (1) is embedded in the groove (21) of the vertical board rail part (2), the two are combined by appropriate means, such as screwing or riveting, to form a complete vertical board part.

Pull plate fitting part (3) also is made independently, and its front end combines pulley (6) and end (31) upper and lower edge (32), (33) design makes inwardly bent into barb and closes shape. The upper edge of the pull plate track (4) extends downward to form a V-shaped groove (41), and then extends outward to form an arc (42), and presses an embedded pull portion (43) on the lower edge to slant outward , so that the end of the tie plate fitting part (3) can be fitted with the tie plate track part (4), so that the upper edge (32) is stuck under the V-shaped groove (41), while the lower edge (33) falls On the embedding part (43), a tight fit is formed, and the two can also be combined by screws or rivets to form the required pull plate as a whole.

Please refer to Fig. 3 and shown in Figure 4, when using the vertical board group and the drawing board group of the present utility model, the arc edge (42) of the drawing board group is to match the arc-shaped card edge (22) inner edge of the vertical board, which can The contact part with a curved surface means that when the drawer is pulled to the most open, the interlocking situation of the two is shown in Figure 4. Due to the expansion of the contact surface and the change of the force point of the fulcrum, it is located between the vertical plate and the drawer. The bending part, hook part and groove part of the plate group have the best support strength, and the contact area of the curved surface can also share part of the force, so that the embedded structure has the strongest supporting effect. It is not necessary to use the thickness of the main body structure to strengthen the strength. According to the test, the common structure needs a thickness of 1.5mm to meet the load standard, but the utility model only needs a thickness of 0.8-1.2m to meet the requirements. Therefore, it is obviously designed with this structure. Possess practical functions that cannot be matched by common structures.

Another advantage of this utility model is that it is very convenient to manufacture and produce. Because the rail parts of the vertical plate and the pull plate are independently manufactured, it can be quickly formed by drawing, and then cut to an appropriate length for application. The fitting part does not need to worry about the bending part or bending part of the track part during pressing, and can also be quickly processed and then combined to form a vertical plate set and a tie plate set, which is known to obtain economical and practical performance. , for the purpose of high efficiency. In addition, due to the reduction of the weight of the finished product, the cost of the product has obviously been reduced, and the transportation cost can also be reduced, which can increase the competitiveness of the utility model and achieve the ultimate goal of the design.

To sum up, the structure of the utility model obviously possesses the original novelty, and because the structure can produce unprecedented practical effects, the utility model has fully complied with the requirements of the patent, and the above is only one comparison of the utility model. For the best embodiment, all simple modifications or transformations based on the spirit of the invention should be included in the scope of protection of this patent.
