Description

Technical Field

[0001] The invention relates to the technical field of hardware accessories, and in particular to a connector and an installation method. Background Art

[0002] At present, drawers are generally composed of a front panel, a side panel, a back panel and a bottom panel. At present, there are two main ways to connect drawers and 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 by 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 longitudinal adjustment structure for adjusting the drawer height is provided on it. Its complex structure makes it difficult to realize automatic assembly of the connector and difficult to assemble and disassemble the drawer and guide rail bracket. Summary of the invention

[0003] The first invention objective of the present invention is to solve the problem that the existing connector has a complex structure and cannot realize automatic assembly, and to provide a connector with a simple structure.

[0004] In order to achieve the above invention object, the present invention adopts the following technical scheme:

[0005] A connector, comprising a base for connecting to a drawer, a locking assembly and a longitudinal adjustment mechanism arranged on the base, wherein the base is connected to the snap-fit ​​structure on the guide rail through the locking assembly, an installation area is provided on the base, a rear portion of the installation area is provided with a clearance opening penetrating backwards and downwards through the base, and the longitudinal adjustment mechanism is arranged on the installation area; the longitudinal adjustment mechanism comprises an adjustment guide rod, both ends of the adjustment guide rod are respectively provided with a transmission part and an adjustment part, an adjustment inclined plane is provided on the adjustment part, the transmission part is arranged in the installation area so as to be movable forwards and backwards, the adjustment part is driven to move backwards through the clearance opening by the rearward movement of the transmission part, so that the adjustment guide rod is connected to the bottom of the drawer and the upper end of the guide rail through the adjustment part, thereby adjusting the height of the drawer by the backward displacement of the adjustment part.

[0006] In the present invention, the adjustment bevel provided on the adjustment part interacts with the contact surface at the bottom of the drawer, thereby achieving fine adjustment of the height. The inclination angle of the bevel determines the sensitivity and range of the adjustment. In practical applications, different bevel angles can be designed to adapt to different adjustment requirements. Compared with the prior art, the design of the longitudinal adjustment mechanism of the present invention achieves fine adjustment of the height by adjusting the cooperation between the guide rod and the adjustment bevel, and the adjustment method and structure are simpler. In addition, the longitudinal adjustment mechanism is integrated in the installation area, which is conducive to realizing automated assembly, which not only reduces the manufacturing cost, but also significantly improves the assembly speed, making the installation and disassembly of the connector between the drawer and the guide rail faster.

In this solution, the driving inclined surface on the driving screw and the transmission inclined surface on the transmission part cooperate with each other to realize the conversion of the rotary motion of the driving mechanism into the linear motion of the adjusting guide rod, thereby realizing the precise adjustment of the drawer height. The precise adjustment and fine-tuning function of the drawer height is realized by the inclination angles of the driving inclined surface and the adjusting inclined surface.

[0009] Furthermore, the installation area is provided with a first installation groove, a second installation groove and a third installation groove, the rod portion of the drive screw and the drive nut are respectively located on the first installation groove and the second installation groove, the handle portion of the drive nut is located on the third installation groove, and the adjustment guide rod is assembled on the third installation groove.

[0012] Furthermore, the handle of the driving screw is in the shape of a right-angled trapezoid, and the adjusting inclined surface is the waist of the right-angled trapezoid.

[0013] Furthermore, a guide protrusion is provided at the bottom of the handle of the driving screw rod, and a slide groove is provided in the installation area which runs longitudinally through the bottom thereof.

In the assembly process of this scheme, the base, the reset member and the buckle are placed in order from bottom to top, and then the three are combined together by the shaft pin. At the same time, a first limiting part is provided on the base to guide and position the installation of the reset member and the buckle, and the first limiting part and the first shaft hole jointly limit the position and posture of the reset member and the buckle on the base. After assembly, the first limiting part cooperates with the reset member to limit the axial freedom of the buckle, so that the rear part of the buckle is pressed against the first limiting part. When the connector is installed on the drawer, it is located at the bottom of the drawer and is connected to the upper rail of the drawer guide rail through the buckle. At this time, the base, the reset member and the buckle are arranged in order from bottom to top. When connecting the guide rail, pressure is applied to the side of the front part of the buckle away from the buckle, and the buckle rotates to the side away from the first limiting part; after the pressure disappears, the buckle is reset under the action of the reset member and buckles to the buckle hole of the guide rail.

[0032] Embodiment 1:

[0033] See also Figure 1-10As shown, this embodiment discloses a connector 1, including a base 10 for connecting with a drawer, and a locking assembly and a longitudinal adjustment mechanism 4 arranged on the base 10, wherein the base is connected to the buckling structure on the guide rail through the locking assembly, and the locking assembly includes a reset member 2 and a buckling member 3; the rear portion is provided with a positioning structure 11, and the positioning structure 11 includes a first shaft 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 shaft hole 23; the buckling member 3 is provided with a buckling portion 31 and a third shaft hole 32, and the buckling portion 31 is provided on one side of the rear portion of the buckling member 3 close to the first limiting portion 111, and is used to engage with the guide rail 6 The first axial hole 115, the second axial hole 23 and the third axial hole 32 are connected in series in sequence through the axial pin 16, so that the base 10, the reset member 2 and the fastening member 3 are connected in sequence, 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 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 excessive rotation of the fastening member 3.

[0034] 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, and 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 caused by 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 it is buckled with the guide rail 6, thereby improving the flexibility and reliability of the buckling.

In this solution, the first limiting portion 111 and the second limiting portion 112 clamp the guide rail 6, so that the connection between the guide rail 6 and the connector 1 is stable.

[0040] 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 are kept tightly connected.

[0041] 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 The first spring pressing portion 114 is disposed at the recessed position 113.
