Description
Technical Field
[0001] The utility model relates to the technical field of drawers, in particular to a connector for a drawer guide rail and a drawer. Background Art
[0002] Current drawers are generally composed of a front panel, side panels, a back panel and a bottom panel. There are currently two main ways to connect drawers to guide rails. One is that the bottom panel and the slide rail are usually fixed with screws, and the other is to use a connector to connect. Compared with the traditional screw connection method, drawer slides connected with connectors can be more easily disassembled and reassembled when repairs or replacement of parts are required. Due to the modular design of the connector, when a component fails, the faulty component can be quickly located and replaced without large-scale disassembly of the entire slide rail or drawer, thereby saving inspection time and maintenance costs. However, the existing connector structure for two-section guide rails is relatively complex, which is not conducive to improving the assembly speed. In particular, the connector needs to be provided with a fastener that is connected to the drawer, but the connection structure between the fastener and the connector is complex and cannot be assembled in an automated manner.

[0006] The connector of the present invention comprises a base, a fastener, and a reset member, all of which are provided with an axial hole. During assembly, the base, reset member, and fastener are arranged in order from bottom to top and then secured together using an axial pin. Furthermore, a first stopper is provided on the base to guide and position the reset member and fastener during installation. The first stopper and the first axial hole together constrain the position of the reset member and fastener on the base. After assembly, the first stopper cooperates with the reset member to limit the axial freedom of the fastener, forcing the rear portion of the fastener to press against the first stopper. When the connector is installed in a drawer, it is located at the bottom of the drawer and connected to the upper rail of the drawer guide rail via the fastener. The base, reset member, and fastener are arranged in order from bottom to top.

[0039] Example 1:
[0040] See also Figure 1-10As shown, this embodiment discloses a connector 1 for a drawer guide rail, comprising a base 10, a reset member 2 and a fastening member 3; the base 10 is used to connect with the drawer 5, and a positioning structure 11 is provided at the rear thereof, wherein the positioning structure 11 comprises a first axis hole 115 and a first limiting portion 111; the reset member 2 is provided with a first pressing portion 21, a second pressing portion 22 and a second axis hole 23; the fastening member 3 is provided with a fastening portion 31 and a third axis hole 32, wherein the fastening portion 31 is provided at the rear of the fastening member 3 on one side close to the first limiting portion 111, and is used to connect with the fastening structure of the guide rail 6; the first axis hole 115 and the second axis hole 23 and the third axial hole 32 are sequentially connected through the axial pin 16, so that the base 10, the reset member 2 and the fastening member 3 are sequentially connected, and the first pressing portion 21 and the side of the fastening member 3 close to the fastening portion 31 are both in contact with the first limiting portion 111, and the second pressing portion 22 is pressed against the side of the fastening member 3 away from the fastening portion 31, and the reset member 2 applies a force toward the side of the first limiting portion 111 to the fastening member 3 through the first pressing portion 21, so that the fastening member 3 remains close to the first limiting portion 111, and the first limiting portion 111 limits the fastening member 3 from excessive rotation.
[0041] The first limiting portion 111 is provided with a first positioning plane 111a on one side close to the buckling portion 31. The buckling portion 31 of the buckling member 3 protrudes backward from the base 10. The buckling member 3 is adapted to the first positioning plane 111a and is provided with a second positioning plane 33, and abuts against the first positioning plane 111a of the first limiting portion 111 through the second positioning plane 33. In this solution, when the buckling member 3 is connected to the base 10, under the action of the reset member 2, the first positioning plane 111a and the second positioning plane 33 will abut against each other; this plane-to-plane contact method can increase the contact area and thus enhance the stability of the connection, avoid positioning deviations due to uneven contact surfaces or manufacturing errors, and improve the accuracy of positioning. In addition, the design of the buckling portion 31 protruding backward ensures that the buckling member 3 will not be hindered by other structures on the base 10 when buckling with the guide rail 6, thereby improving the flexibility and reliability of the buckling.

The base 10 is connected to the guide rail 6 via the recess 113, and the first limiting portion 111 and the second limiting portion 112 cooperate to limit the left-right displacement of the guide rail 6. In this embodiment, the first limiting portion 111 and the second limiting portion 112 clamp the guide rail 6, ensuring a stable connection between the guide rail 6 and the connector 1.
[0047] The second limiting portion 112 is elastic, and the base 10 is elastically pressed against the side surface of the guide rail 6 through the second limiting portion 112 , so that the guide rail 6 and the base 10 maintain a tight connection.
[0048] The positioning structure 11 further includes a first elastic pressing portion 114. The first limiting portion 111 includes a first convex portion and a second convex portion. One end of the first convex portion is connected to the second convex portion to form a shaped structure, and forming a recess 113, the first elastic portion 114 is provided at the recess 113, the first elastic portion 114 and the buckling portion 31 are positioned front to back oppositely, and the two cooperate to achieve front and back fixation of the connector 1 and the guide rail 6.

The first limiting portion 111 and the first axial hole 115 jointly limit the position and posture of the reset member 2 and fastener 3 on the base 10. After assembly, the first limiting portion 111 cooperates with the reset member 2 to limit the axial freedom of the fastener 3, causing the rear portion of the fastener 3 to press against the first limiting portion 111. When the connector 1 is installed on the drawer 5, it is located at the bottom of the drawer 5 and is connected to the upper rail of the drawer 5 guide rail 6 via the fastener 3. At this point, the base 10, reset member 2, and fastener 3 are arranged in order from bottom to top. When connecting to the guide rail 6, pressure is applied to the front of the fastening member 3, away from the fastening portion 31, causing the fastening member 3 to rotate away from the first limiting portion 111. After the pressure is released, the fastening member 3 returns to its original position under the force of the reset member 2 and fastens to the fastening hole of the guide rail 6. Compared with the existing technology, the assembly structure and method of the connector 1 are simple, enabling fully automated assembly.
