Description

Technical Field

[0001] The utility model relates to the technical field of slide rails, in particular to a self-lubricating slide rail with strong durability. Background Art

[0002] Slide rails, also known as guide rails and slideways, refer to the hardware connection parts fixed to the cabinet of furniture for the drawers or cabinet panels of furniture to move in and out. Slide rails are suitable for connecting drawers of wooden and steel drawers such as cabinets, furniture, document cabinets, bathroom cabinets, etc. If the hinge is the heart of the cabinet, then the slide rail is the kidney. Whether the drawers of all sizes can be pushed and pulled freely and smoothly, and how they bear weight, all depends on the support of the slide rails. From the current technology, the bottom slide rail is better than the side slide rail, and the overall connection with the drawer is better than the three-point connection. The materials, principles, structures, and craftsmanship of drawer slides vary greatly. High-quality slides have low resistance, long life, and smooth drawers. In order to facilitate users to push and pull drawers smoothly, slides are usually installed between the drawer and the cabinet body, such as the C-type slide installed on the side of the drawer. It is generally composed of a fixed rail installed on the cabinet body, a middle rail and a movable rail installed on the drawer. In order to facilitate the pulling out of the middle rail and the movable rail, a fixed rail bead rack with steel balls is provided between the fixed rail and the middle rail, and a movable rail bead rack with steel balls is provided between the movable rail and the middle rail. In addition, in order to prevent the bead rack and the track from detaching from each other, a limit structure is generally adopted.

[0003] After searching, the Chinese patent publication number CN110720766B discloses a silent slide rail, which includes a sliding component, and the sliding component includes a movable rail, a movable rail bead rack, a middle rail, a fixed rail bead rack, and a fixed rail. It is characterized in that: a buffer is provided at the collision point of the two sliding components that collide. The middle rail includes a small and medium rail located on one side and a medium and large rail located on the other side, the small and medium rails are connected to the movable rail through the movable rail bead frame, and the medium and large rail is connected to the fixed rail through the fixed rail bead frame; the movable rail is provided with the buffer at the front and rear ends, and the movable rail bead frame is provided with the buffer at the front and rear ends; the small and medium rails are provided with the buffer at the front end, the medium and large rails are provided with the buffer at the front and rear ends, and the fixed rail is provided with the buffer at the front end; the fixed rail is provided with a bidirectional buffer at the front end, and the small and medium rails are provided with a bidirectional buffer at the front end; the buffer includes an elastic buffer part capable of buffering and a fixed part for connecting with a sliding part; the buffer includes a first buffer part, a second buffer part, a third buffer part and a fourth buffer part; the movable rail front end and the medium and large rail front end are connected with the first buffer part, the fixed rail front end and the small and medium rail front end are connected with the second buffer part, the second buffer part is a bidirectional buffer part, the movable rail rear end and the medium and large rail rear end are connected with the third buffer part, and the movable rail bead frame front and rear ends and the fixed rail bead frame front and rear ends are connected with the fourth buffer part. The above patent has the following shortcomings: Although the patent does not produce sound when pulled, it still needs to be lubricated regularly to maintain lubrication, otherwise the drawer cannot be pulled open due to insufficient lubrication of the slide rail. In view of this, we propose a self-lubricating slide rail with strong durability. Utility Model Content

[0023] In the prior art, Chinese Patent Publication No. CN110720766B discloses a silent slide rail.

[0024] The inventor found that although the patent does not produce sound when pulling, it still needs to be lubricated regularly to maintain lubrication, otherwise the drawer will not be able to be pulled open due to insufficient lubrication of the slide rail.

[0025] like Figure 1-3As shown, a self-lubricating slide rail with strong durability includes a slide rail body 1, a sleeve 2, a moving mechanism 4, an oil spray nozzle 5, and a buffer mechanism 6; the sleeve 2 is slidably connected to the side of the slide rail body 1; the moving mechanism 4 is arranged on the back of the sleeve 2 and can drive the oil spray nozzle 5 to move; the oil spray nozzle 5 is arranged on the back of the sleeve 2 and can spray lubricating oil; the buffer mechanism 6 is arranged on the left side of the sleeve 2, and the gap between the slide rail body 1 and the sleeve 2 forms a lubricating oil groove 3.

[0026] The moving mechanism 4 includes a left side plate 41, which is fixedly connected to the back side of the sliding sleeve 2. A motor 42 is fixedly connected to the left side of the left side plate 41, and the motor 42 is fixedly connected to the left side of the left side plate 41. The right side output end of the motor 42 passes through the left and right ends of the left side plate and is fixedly connected to a threaded rod 43. The right side of the threaded rod 43 is rotatably connected to a right side plate 44 through a bearing. A movable block 45 is threadedly connected to the middle part of the threaded rod 43. A slide groove 47 is penetrated through the back side of the sliding sleeve 2, and a slider 46 is slidably connected inside the slide groove 47. The back side of the slider 46 is fixedly connected to the movable block 45, and the fuel injector 5 is fixedly installed on the front side of the slider 46.

[0027] The buffer mechanism 6 includes a fixed plate 61, which is fixedly connected to the front side of the sliding sleeve 2. A sliding rod 62 slides through the interior of the fixed plate 61. The left end of the sliding rod 62 is fixedly connected to a limiting plate 63. The right end of the sliding rod 62 is fixedly connected to a rubber plate 64. A spring 65 is sleeved on the outside of the sliding rod 62. The left end of the spring 65 is fixedly connected to the fixed plate 61, and the right end of the spring 65 is fixedly connected to the rubber plate 64.

[0028] The working principle of the utility model is as follows:

[0029] The motor 42 is turned on to drive the threaded rod 43 to rotate. The rotation of the threaded rod 43 drives the slider 46 to move left and right. The left and right movement of the slider 46 drives the oil spray nozzle 5 to spray lubricating oil inside the lubricating oil groove 3, thereby preventing the slide rail body 1 from being unable to slide due to insufficient lubricating oil. When the sliding sleeve 2 slides, it will hit the rubber plate 64. The rubber plate 64 will compress the spring 65 when it is hit and drive the sliding rod 62 to move, thereby completing the buffering of the impact force generated by the collision of the sliding sleeve 2.

[0030] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
