Description

Technical Field

[0001] The utility model relates to the technical field of drawer guide rails, in particular to a self-lubricating ball-bearing type drawer guide rail. Background Art

[0002] Before the advent of ball bearing drawer guides, traditional drawer guides mostly used simple wooden or metal rails. Wooden slides are prone to wear and tear, becoming stuck and choppy over time, and are unable to withstand heavy loads. While metal slides are stronger than wooden ones, they have a higher coefficient of friction, requiring greater force to open and close drawers and also tend to produce noise.

[0003] After a period of use, the internal ball bearings of drawer guides are prone to rust, which increases friction and makes opening more difficult. The existing ones require users to lubricate the internal ball bearings themselves, which makes drawer disassembly more inconvenient. In view of this, a self-lubricating ball bearing drawer guide is needed. Utility Model Content

[0004] The purpose of the present utility model is to provide a self-lubricating ball-bearing drawer guide rail to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a self-lubricating ball-bearing drawer guide rail, comprising a cabinet body, a drawer provided on the side of the cabinet body, a ball bearing being connected in a rolling manner inside the cabinet body, a slide bar being fixedly mounted on the side wall of the cabinet body, a fixed plate being fixedly mounted on the outer wall of the drawer, a handle being slidably penetrated inside the fixed plate, a lubricating mechanism being provided inside the slide bar, a stopping mechanism being provided inside the slide bar, and the lubricating mechanism comprising:

[0006] a slide plate, the slide plate being slidably connected to the inner wall of the slide bar;

[0007] The oil tank is fixedly mounted on the outer wall of the skateboard, an elastic telescopic rod is fixedly mounted on the inner wall of the oil tank, a sealing block is fixedly mounted on the end of the elastic telescopic rod, the sealing block slides through the interior of the oil tank, and a lubricating ball is rollingly connected to the sealing block.

[0008] Preferably, an adjustment plate is slidably connected to the inner wall of the slide bar, the adjustment plate is hinged to one end of the support rod, and the other end of the support rod is hinged to the slide plate.

[0009] Preferably, an adjusting rod is fixedly installed on the outer wall of the adjusting plate, the end of the adjusting rod is fixedly connected to the outer wall of the handle, a load-bearing spring is sleeved on the outer wall of the adjusting rod, one end of the load-bearing spring is fixedly connected to the outer wall of the adjusting rod, and the other end of the load-bearing spring is fixedly connected to the inner wall of the slide bar.

[0010] Preferably, the braking mechanism includes a fixed block, and the fixed block is fixedly mounted on the outer wall of the adjusting rod.

[0011] Preferably, a rotating rod is rotatably connected to the inner wall of the fixed block, the outer wall of the rotating rod is fixedly connected to one end of a torsion spring, and the other end of the torsion spring is fixedly connected to the inner wall of the fixed block.

[0021] like Figure 1-Figure 4As shown, the utility model provides a technical solution: a self-lubricating ball-bearing drawer guide rail, comprising a cabinet body 1, a drawer 2 is provided on the side of the cabinet body 1, and storage is performed by pushing the drawer 2 into the interior of the cabinet body 1. Balls 3 are connected to the interior of the cabinet body 1 for rolling, a slide 4 is fixedly installed on the side wall of the cabinet body 1, a fixed plate 5 is fixedly installed on the outer wall of the drawer 2, a handle 8 is slidingly passed through the interior of the fixed plate 5, a lubrication mechanism 6 is provided inside the slide 4, and a stopping mechanism 7 is provided inside the slide 4.

[0022] In this embodiment, a lubrication mechanism 6 is provided inside the slide bar 4. The lubrication ball 65 in the lubrication mechanism 6 is squeezed by the upper ball 3, so that the lubrication ball 65 can drive the sealing block 64 to move into the oil tank 62 to open the gap. The ball 3 is automatically lubricated by the rotation of the lubrication ball 65. At the same time, the elastic force of the elastic telescopic rod 63 can reset the sealing block 64 to close the gap to prevent leakage of the lubricating oil.

[0023] In this embodiment, a stopping mechanism 7 is provided inside the slide 4. Through the inertia of the rubber block 75 in the stopping mechanism 7, the connecting block 74 can drive the rubber block 75 to rotate right and fit the inner wall of the slide 4 to stop, preventing the adjusting rod 68 from continuing to move rightward and causing the ball 3 to be lubricated again, resulting in excessive lubricating oil.

[0024] The above-mentioned lubricating mechanism 6 includes a slide plate 61, which is slidably connected to the inner wall of the slide bar 4, and an oil tank 62 is fixedly installed on the outer wall of the slide plate 61. The oil tank 62 can drive the lubricating ball 65 above the sealing block 64 to move to the outside of the slide bar 4, and an elastic telescopic rod 63 is fixedly installed on the inner wall of the oil tank 62. The end of the elastic telescopic rod 63 is fixedly installed with a sealing block 64. The elastic force of the elastic telescopic rod 63 can reset the sealing block 64 to close the gap, and the sealing block 64 slides through the interior of the oil tank 62. A lubricating ball 65 is rollingly connected to the sealing block 64. The ball 3 squeezes the lubricating ball 65, which can drive the sealing block 64 to move into the interior of the oil tank 62 to open the gap, and the rotation of the lubricating ball 65 can make The ball 3 is lubricated, and an adjusting plate 66 is slidably connected to the inner wall of the slide 4. The adjusting plate 66 is hinged to one end of the support rod 67, and the other end of the support rod 67 is hinged to the slide 61. The adjusting plate 66 is driven to the right by the adjusting rod 68 to pull the end of the support rod 67, so that the slide 61 can drive the oil tank 62 to move upward. An adjusting rod 68 is fixedly installed on the outer wall of the adjusting plate 66. When the ball 3 is rusted, the friction force is large, and the adjusting rod 68 can be driven to the right relative to the slide 4 through the handle 8. The end of the adjusting rod 68 is fixedly connected to the outer wall of the handle 8, and a load-bearing spring 69 is sleeved on the outer wall of the adjusting rod 68. One end of the load-bearing spring 69 is fixedly connected to the outer wall of the adjusting rod 68, and the other end of the load-bearing spring 69 is fixedly connected to the inner wall of the slide 4.

[0025] The above-mentioned braking mechanism 7 includes a fixed block 71, which is fixedly mounted on the outer wall of the adjusting rod 68. A rotating rod 72 is rotatably connected to the inner wall of the fixed block 71. The outer wall of the rotating rod 72 is fixedly connected to one end of a torsion spring 73, and the other end of the torsion spring 73 is fixedly connected to the inner wall of the fixed block 71. A connecting block 74 is fixedly mounted on the outer wall of the rotating rod 72, and a rubber block 75 is fixedly mounted on the outer wall of the connecting block 74. Through inertia, the connecting block 74 can drive the rubber block 75 to rotate rightward and fit the inner wall of the slide bar 4 to stop, preventing the adjusting rod 68 from continuing to move rightward to lubricate the ball 3 again, resulting in excessive lubricating oil.

[0026] In this embodiment, the drawer 2 is first pushed into the interior of the cabinet 1 for storage. When it is needed, the handle 8 is pulled to move the drawer 2 to the outside of the cabinet 1 for use. When the ball bearing 3 is rusted, the friction force is large. At this time, the handle 8 will drive the adjusting rod 68 to move to the right relative to the slide 4, and then the adjusting rod 68 will drive the adjusting plate 66 to pull the end of the support rod 67 to the right. Then, through the hinge between the support rod 67 and the slide 61, the slide 61 drives the oil tank 62 to move upward, and then the oil tank 62 drives the lubricating ball 65 above the sealing block 64 to move to the outside of the slide 4. The ball bearing 3 squeezes the lubricating ball 65, so that the lubricating ball 65 drives the sealing block 64 to move into the interior of the oil tank 62 to fill the gap. The opening is opened, and then the ball 3 is lubricated by the rotation of the lubricating ball 65. When the ball 3 is lubricated, the friction force is reduced, and the drawer 2 can be opened normally. The slide plate 61 drives the oil tank 62 to move downward to reset. At the same time, the elastic force of the elastic telescopic rod 63 resets the sealing block 64 to close the gap. When the user opens the drawer 2 too quickly, the handle 8 will drive the fixed block 71 on the outer wall of the adjusting rod 68 to move to the right. Since the fixed block 71 drives the upper rubber block 75 to move to the right too quickly, the connecting block 74 drives the rubber block 75 to rotate to the right through inertia and fits the inner wall of the slide bar 4 to stop, preventing the adjusting rod 68 from continuing to move to the right, thereby lubricating the ball 3 again and causing excessive lubricating oil.

[0027] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
