Description

Technical Field

[0001] The utility model relates to the field of furniture accessories, and more specifically, to a slide rail accessory for furniture. Background Art

[0002] Metal accessories for furniture include connectors, such as screws, nuts, bolts, rivets, etc., which are used to connect the various parts of furniture to ensure the stability of the furniture structure; slide rails, which are used to push and pull drawers so that drawers can be opened and closed smoothly; hinges, which are used to connect cabinet doors and cabinet bodies so that cabinet doors can be opened and closed smoothly; handles and pulls, which are used to facilitate the opening of furniture doors or drawers, and also have a certain decorative effect. The slide rail accessories in furniture generally include fixed rails that are fixed inside the cabinet body to provide a sliding path and support for the drawer; movable rails are installed at the bottom of the drawer body and cooperate with the fixed rails so that the drawer can slide smoothly on the slide rails.

[0003] With the existing slide rail accessories, fixed rails are generally used in conjunction with movable rails. However, different sizes of movable rails are required for drawers of different sizes, so it is necessary to prepare a variety of matching fixed rails, which has low practicality. During installation, different installation spaces must be reserved and corresponding installation methods must be adopted according to the different fixed rails, which increases the difficulty of installation and reduces the efficiency of installation. One fixed rail cannot be used in conjunction with a variety of movable rails of different sizes to improve installation efficiency, reduce installation difficulty, and enhance practicality. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a slide rail accessory for furniture that can be used with a fixed rail and a plurality of movable rails of different sizes, thereby improving installation efficiency, reducing installation difficulty, and enhancing practicality.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A slide rail accessory for furniture comprises a fixed rail and a movable rail, wherein a connecting plate is installed in the movable rail, the fixed rail comprises a sliding channel, the movable rail slides in the sliding channel, a spring is installed on the inner wall at one end of the sliding channel, a guide plate is fixed on the spring, a ball is rotatably connected to the guide plate, a guide groove cooperating with the ball is opened at one end of the movable rail, the ball rolls in the guide groove, a sliding block is installed on the inner wall at the other end of the sliding channel, and a positioning groove slidably connected to the sliding block is opened at the other end of the movable rail.

[0007] It is further configured that a ball groove cooperating with the ball is opened on the guide plate, an axial hole is opened on the ball, an axle rod cooperating with the ball is provided in the ball groove, one end of the axle rod is fixed on the inner wall of one end of the ball groove, and the other end of the axle rod passes through the axial hole and is fixed on the inner wall of the other end of the ball groove, and the axle rod is rotatably connected to the axial hole.

[0008] It is further configured that the end of the slider is arc-shaped.

[0009] It is further configured that a buffer pad is installed on the inner wall of the sliding channel.

[0010] By adopting the above technical scheme, the beneficial effects of the utility model are as follows: the drawer is connected to the connecting plate on the movable rail, the fixed rail is installed on the cabinet body that matches the drawer, and the movable rail slides in the sliding channel through the cooperation between the guide groove on the movable rail and the ball bearing on the guide plate and the cooperation between the positioning groove on the movable rail and the slider for sliding. When a larger movable rail is needed, the movable rail cooperates with the ball bearing on the guide plate to squeeze the guide plate, and the spring compression on the guide plate facilitates the installation of the larger movable rail in the sliding channel for sliding. When the movable rail squeezes the guide plate, it will not affect the movement of the ball bearing in the guide groove, thus avoiding the need to prepare multiple fixed rails, and achieving the goal of one fixed rail being used in conjunction with multiple movable rails of different sizes, thereby improving installation efficiency, reducing installation difficulty, and enhancing practicality.

[0016] Reference Figures 1 to 4 The utility model is further described in detail.

[0017] A slide rail accessory for furniture, comprising a fixed rail 1 and a movable rail 2, wherein a connecting plate 3 for connecting a drawer is installed in the movable rail 2, the fixed rail 1 comprises a sliding channel 4, the movable rail 2 slides in the sliding channel 4, a spring 5 is installed on the inner wall at one end of the sliding channel 4, a guide plate 6 is fixed on the spring 5, a ball 7 is provided on the guide plate 6, and a ball groove 11 cooperating with the ball 7 is opened on the guide plate 6, an axial hole 12 is opened on the ball 7, a shaft rod 13 cooperating with the ball 7 is provided in the ball groove 11, one end of the shaft rod 13 is fixed to the inner wall at one end of the ball groove 11, the other end of the shaft rod 13 passes through the axial hole 12 and is fixed to the inner wall at the other end of the ball groove 11, the shaft rod 13 is rotatably connected to the axial hole 12, a guide groove 8 cooperating with the ball 7 is opened at one end of the movable rail 2, the ball 7 rolls in the guide groove 8, a slider 9 with an arc-shaped end is installed on the inner wall at the other end of the sliding channel 4, and a positioning groove 10 slidably connected to the slider 9 is opened at the other end of the movable rail 2.

[0018] Working principle: the drawer is connected to the connecting plate 3 on the movable rail 2, the fixed rail 1 is installed on the cabinet body matched with the drawer, the movable rail 2 is placed in the sliding channel 4 and the guide groove 8 corresponds to the guide plate 6, the positioning groove 10 corresponds to the slider 9, the ball 7 on the guide plate 6 is rotatably connected with the shaft hole 12 on the ball 7 through the shaft rod 13 in the ball groove 11 to realize the rotation of the ball 7 on the guide plate 6, and the ball 7 rolls in the guide groove 8 on the movable rail 2 and the slider 9 slides in the positioning groove 10 on the movable rail 2. The arc-shaped end of the slider 9 facilitates the sliding of the slider 9 in the positioning groove 10, so that the movable rail 2 slides smoothly in the sliding channel 4, which is convenient for the drawer to slide and open and close. The setting of the ball 7 reduces the movable rail 2. The friction between the movable rail 2 and the fixed rail 1 makes the movable rail 2 slide more smoothly in the sliding channel 4, thereby improving practicality. When a larger movable rail 2 is needed, the movable rail 2 squeezes the guide plate 6 through the ball 7 when the ball 7 on the guide plate 6 rolls in the guide groove 8, and the spring 5 on the guide plate 6 is compressed to facilitate the larger movable rail 2 to be installed in the sliding channel 4 and slide. When the movable rail 2 squeezes the guide plate 6, it will not affect the movement of the ball 7 in the guide groove 8 and the ball groove 11, thereby ensuring that the movable rail 2 slides normally in the sliding channel 4, avoiding the need to prepare multiple fixed rails 1, and achieving that one fixed rail 1 can be used in conjunction with multiple movable rails 2 of different sizes, thereby improving installation efficiency, reducing installation difficulty, and enhancing practicality.

[0019] A buffer pad 14 is installed on the inner wall of the sliding channel 4 and is placed at the bottom of the sliding channel 4 to reduce the impact force generated when the movable rail 2 slides in the sliding channel 4 and hits the bottom of the sliding channel 4, thereby avoiding damage to the movable rail 2 and the fixed rail 1 and affecting use, further enhancing practicality.

[0020] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any common changes and substitutions made by those skilled in the art within the technical solution of the present invention should be included in the protection scope of the present invention.
