Description

Technical Field

[0001] This utility model belongs to the technical field of slide rail devices, specifically relating to slide rail devices and storage cabinets. Background Technology

[0002] Drawer slides are widely used in furniture, cabinets, and office equipment to ensure smooth operation of drawers or moving parts. Traditional drawer slides typically consist of inner, middle, and outer rails, connected by ball bearings. However, during installation, when the inner rails are fixed to the cabinet sidewall with self-tapping screws, wood chips can be generated during drilling. These wood chips may enter the drawer slide and accumulate in the ball bearing mechanism, causing jamming, abnormal noises, or even damage to the ball bearing structure, affecting the normal operation and lifespan of the drawer slide. Utility Model Content

[0003] The purpose of this utility model is to overcome the problem that in existing slide rail devices, when the inner rail is fixed to the side wall of the cabinet with self-tapping screws, wood chips can easily enter the slide rail device through the screw holes, affecting the normal sliding of the slide rail. The present invention provides a wood chip storage groove with a wood chip storage space in the inner rail, thereby reducing or avoiding the wood chips entering the slide rail device and storage cabinet through the screw holes.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] The slide rail device includes: an inner rail component, a middle rail component, and an outer rail component. The inner rail component and the middle rail component are slidably connected by a first ball bearing structure, and the middle rail component and the outer rail component are slidably connected by a second ball bearing structure. The inner rail component is used to connect with the side wall of the cabinet cavity. The outer side of the inner rail component is provided with an inwardly recessed chip collection groove, and the inner side wall of the chip collection groove is provided with a first connecting hole connecting the two sides of the inner rail component.

[0006] Compared with existing technologies, the slide rail device of this utility model, by setting an inwardly recessed chip collection groove on the outer side of the inner rail component and opening a first connecting hole connecting the two sides on its inner side wall, can effectively collect the wood chips generated during the installation of self-tapping screws, reduce or prevent wood chips from entering the ball bearing structure between the inner rail component and the middle rail component, thereby avoiding problems such as sliding jamming and abnormal noise, and ensuring smooth operation of the slide rail. The chip collection groove has a simple structure and is easy to process, which reduces production costs and improves assembly efficiency. At the same time, it reduces the wear of the ball bearing structure, extends the service life of the slide rail, and has strong compatibility. It can be widely used in the slide rail devices of various furniture, cabinets and office equipment, and has significant practical value.

[0007] Furthermore, the outer side of the inner rail component is stamped with a chip storage stamping part extending inward, and the chip storage groove is formed in the inner groove of the chip storage stamping part. With this arrangement, the chip storage stamping part and the chip storage groove formed by the stamping process are integrally formed on the outer side of the inner rail component, which not only maintains the integrity and strength of the structure, but also makes the chip storage space perfectly integrated with the inner rail component. This ensures effective collection of wood chips, avoids additional processing steps, and improves production efficiency. At the same time, the stamped chip storage groove structure is more precise and reliable, which is conducive to the directional collection and cleaning of wood chips, further improving the chip prevention performance and long-term stability of the slide rail device.

[0008] Furthermore, the first connecting hole is either a circular hole or an elliptical hole. By designing the first connecting hole as a circular hole or an elliptical hole, it ensures the smooth discharge of wood chips and air circulation, while maintaining the strength of the connection structure. Circular holes are easy to process and distribute force evenly, while elliptical holes provide a larger chip discharge space and installation tolerance. The two hole types can be flexibly applied according to actual needs, ensuring functionality while taking into account the convenience of the production process and the reliability of the structure.

[0009] Furthermore, the chip storage trough is rectangular in shape, and its length extends along the length of the inner rail component. This design, by making the chip storage trough rectangular in shape and extending along the length of the inner rail component, not only perfectly matches the linear motion characteristics of the slide rail, allowing the wood chips to be evenly distributed and stored along the track direction, avoiding local accumulation, but also the regular rectangular structure facilitates stamping and dimensional control. While ensuring maximum chip storage capacity, it maintains the structural strength of the inner rail component. This length-direction extension design also ensures that wood chips generated at different installation positions can be effectively collected, significantly improving the reliability and consistency of the chip prevention effect.

[0010] Furthermore, the chip storage trough is provided with one or more of the first connection holes.

[0011] Furthermore, the middle rail component has a clearance groove corresponding to the chip storage stamping part; by setting the clearance groove at the position of the middle rail component corresponding to the chip storage stamping part, the chip storage structure of the middle rail component and the inner rail component are perfectly matched, which not only ensures that there is no interference between the components of the slide rail device during the pulling process and the movement is smoother, but also provides a larger capacity for the chip storage groove. At the same time, the design of the clearance groove optimizes the overall space utilization of the slide rail without affecting the structural strength of the middle rail component.

[0012] Furthermore, multiple chip storage grooves are provided along the length of the inner rail component.

[0013] Furthermore, the sawdust collection trough has a funnel-shaped structure, and the inner diameter of the sawdust collection trough gradually increases along the outer side. This design significantly improves the sawdust collection efficiency, effectively stores enough sawdust, and allows sawdust to slide more smoothly into the trough, avoiding accumulation at the trough opening. Moreover, the enlarged opening design facilitates subsequent cleaning and maintenance.

[0014] Furthermore, the outer rail component is provided with a second connecting hole, which is either a circular hole or an elliptical hole.

[0015] The storage cabinet includes a cabinet body and drawers, and also includes the aforementioned slide rail device. The inner slide rail is fixed to the cabinet body by screws passing through a first connecting hole and connecting to the side wall of the cabinet cavity. The outer slide rail is provided with a second connecting hole, and the outer slide rail is fixed to the drawer by screws passing through the first connecting hole.

[0016] Compared with existing technologies, the storage cabinet of this utility model features a sliding rail device with an inwardly recessed chip collection groove on the outer side of the inner rail component and a first connecting hole on its inner side wall connecting the two sides. This effectively collects wood chips generated during the installation of self-tapping screws, reducing or preventing wood chips from entering the ball bearing structure between the inner and middle rail components. This avoids problems such as sliding jamming and abnormal noise, ensuring smooth operation of the sliding rail. The chip collection groove has a simple structure and is easy to process, which reduces production costs and improves assembly efficiency. It also reduces wear on the ball bearing structure, extends the service life of the sliding rail, and has strong compatibility. It can be widely used in the sliding rail devices of various furniture, cabinets, and office equipment, and has significant practical value. Attached Figure Description

At the same time, the stamped chip storage groove 11 structure is more precise and reliable, which is conducive to the directional collection and cleaning of wood chips, and further improves the chip prevention performance and long-term stability of the slide rail device 10.

[0027] See Figures 1 to 3 In one embodiment, the first connecting hole 12 is a circular hole or an elliptical hole. By setting it in this way, by designing the first connecting hole 12 as a circular hole or an elliptical hole, it is possible to ensure the smooth discharge of wood chips and air circulation, while maintaining the strength of the connection structure. Circular holes are easy to process and the force is evenly distributed, while elliptical holes provide a larger chip discharge space and installation tolerance. The two hole types can be flexibly applied according to actual needs, ensuring functionality while taking into account the convenience of production process and structural reliability.

[0028] See Figures 1 to 3 In one embodiment, the chip storage trough 11 is rectangular in shape, and its length extends along the length of the inner rail 1.

With this setting, the sawdust collection efficiency is significantly improved, so as to effectively store enough sawdust, while allowing sawdust to slide into the trough more smoothly, avoiding accumulation at the trough opening, and the enlarged opening design facilitates subsequent cleaning and maintenance.

[0033] See Figures 1 to 3 In one embodiment, the outer rail 3 is provided with a second connecting hole (not shown), which is a circular hole or an elliptical hole.
