一种可转向的滑轨结构

Abstract

本实用新型涉及滑轨结构技术领域，尤其涉及一种可转向的滑轨结构，包括条状的上轨和下轨。下轨设有滑槽且后端为三面开口结构，该三面开口结构的后端连接有连接座，连接座内置可绕轴线旋转的滚轴。上轨前端配备转向装置，该转向装置由前柱、左杆、右杆、后柱、转向杆和联动轴组成。转向杆的一端与前柱可旋转连接，另一端与联动轴可转动连接。在使用过程中，上轨沿滑槽向后滑动，当左杆和右杆被连接座的凸出部挡住，阻止其继续后移时，上轨开始绕滚轴向上旋转，同时带动联动轴同步旋转。联动轴进一步驱动转向杆绕前柱旋转，使转向杆由与上轨平行的位置转变为与上轨相交的位置，从而实现滑轨结构的转向动作，有效提升了滑轨结构的灵活性。

Claims

1. A steerable slide rail structure, characterized by, The device includes a strip-shaped upper rail and a lower rail. The rear end of the lower rail is a three-sided open structure, open at the top, bottom, and rear. A roller device is connected to this three-sided open structure. The roller device includes a roller and a connecting seat with an upward opening. The two ends of the roller are respectively connected to the left and right walls of the connecting seat. The roller can rotate around its axis. The connecting seat is connected to the rear end of the three-sided open structure, and the upward-opening rear wall extends upward to form a protrusion. The lower rail is provided with a sliding groove. A steering device is provided at the front end of the upper rail. The steering device includes a front column, a rear column, a left rod, a right rod, a steering rod, and a linkage shaft. The front column passes through a through hole at the front end of the steering rod, and the steering rod can rotate around the front column. The left end of the front column is connected to... The front end of the left rod is connected to the front end of the right rod, and the rear end of the steering rod is rotatably connected to the linkage shaft. A hollow groove is provided on the bottom surface of the upper rail. The linkage shaft and the rear rod are located in the hollow groove, with the linkage shaft located above the rear rod. The front rod, the left rod, and the right rod are all located outside the hollow groove. The left end of the rear rod passes through the through hole of the hollow groove and is connected to the rear end of the left rod. The right end of the rear rod passes through the through hole of the hollow groove and is connected to the rear end of the right rod. The front rod, the left rod, the rear rod, and the right rod are connected end to end to form a rectangular frame structure. The left rod and the right rod are both located in the sliding groove and can slide back and forth along the sliding groove. When the upper rail slides backward along the groove until both the left and right rods are blocked by the protrusion, and the upper rail rotates upward around the roller, the upper rail drives the linkage shaft to rotate upward synchronously. At the same time, the linkage shaft drives the steering rod to rotate upward around the front column until it intersects with the upper rail.

2. The steerable slide rail structure of claim 1, wherein, The steering device further includes a first roller and a second roller. The front column passes through the central through hole of the first roller and the central through hole of the second roller, respectively. Both the first roller and the second roller can rotate around the front column. When the upper rail slides back and forth along the slide groove, both the first roller and the second roller roll into contact with the bottom wall of the slide groove.

3. The steerable slide rail structure of claim 2, wherein, The front end of the steering rod is located between the first roller and the second roller.

4. The steerable slide rail structure of claim 1, wherein, A third roller is also provided in the middle of the upper rail. The third roller is located in the hollow groove and extends out of the bottom of the hollow groove through the through hole of the hollow groove. When the upper rail slides back and forth along the slide groove, the third roller makes rolling contact with the bottom wall of the slide groove.

5. The steerable slide rail structure of claim 1, wherein, A through slot for the steering rod to extend is provided at the bottom of the hollow groove in the area corresponding to the steering rod.

6. The steerable slide rail structure of claim 1, wherein, The rear end of the lower rail is also provided with a fourth roller and a fifth roller. The two ends of the roller pass through the central through hole of the fourth roller and the central through hole of the fifth roller, respectively, and are connected to the left and right walls of the connecting seat.

7. The steerable slide rail structure of claim 6, wherein, Both the fourth roller and the fifth roller are separated from the bottom wall of the connecting seat.

8. The steerable slide rail structure of claim 1, wherein, The left and right rods have the same structure, and the side facing the protrusion is a semi-circular structure, while the side of the protrusion facing the left and right rods is an arc-shaped structure. When both the left and right rods are blocked by the protrusion, the arc-shaped structure surrounds the part of the surface that contacts the semi-circular structure.

9. The steerable slide rail structure of claim 1, wherein, A locking device is also provided at the rear end of the upper rail. The locking device includes a pawl, a connecting post, and a mechanical lock. The connecting post passes through the through hole in the middle of the pawl and is connected to the left and right walls of the upper rail. The pawl can rotate around the connecting post. The mechanical arm of the mechanical lock is connected to the rear end of the pawl, and the pawl body is located at the front end of the pawl. When the mechanical lock rotates to the locked position, the mechanical lock drives the pawl to rotate around the connecting post through the mechanical arm, so that the pawl body locks the roller.

10. The steerable slide rail structure of claim 9, wherein, The rear end of the hook is provided with an L-shaped groove; when the mechanical lock is rotated to the locked position, the mechanical arm is located in the vertical part of the L-shaped groove, and when the mechanical lock is rotated to the unlocked position, the mechanical arm is located in the horizontal part of the L-shaped groove.
