Detailed Description
Referring to fig. 1 to 8, a linked slide rail includes:
A fixed rail 10;
The movable rail 20 is installed on the fixed rail 10 and can slide along the fixed rail 10;
The middle rail 30 is positioned between the fixed rail 10 and the movable rail 20, the middle rail 30 can slide between the fixed rail 10 and the movable rail 20, a gear 42 is arranged on the middle rail 30, and the gear 42 penetrates through the middle rail 30 and protrudes out of two sides of the middle rail 30;
The first rack 40 is arranged on the fixed rail 10;
And the second rack 41 is arranged on the movable rail 20, the first rack 40 and the second rack 41 are respectively positioned at two sides of the middle rail 30, and the first rack 40 and the second rack 41 are both meshed with the gear 42.
The first rack 40 is installed on the fixed rail 10, the second rack 41 is installed on the movable rail 20, a gear 42 is provided on the middle rail 30 between the fixed rail 10 and the movable rail 20, the first rack 40 and the second rack 41 are engaged with the upper and lower sides of the gear 42, so that when the fixed rail 10 moves relative to the movable rail 20, the first and second racks 40 and 41 will synchronously drive the gear 42 to move, thereby driving the middle rail 30 to move, and the movement state of the gear 42 is opposite to the movement state of the first rack 40 and the second rack 41, when the fixed rail 10 and the movable rail 20 move to any position, both the first 40 and second 41 racks move the gear 42 to a fixed position, therefore, when the sliding rail is used, the position of the middle rail 30 is quite clear, so that the fixed rail 10 and the movable rail 20 can be pulled more stably, and the strength of the sliding rail can be better enhanced.
Further improve, when directly installing gear 42 on well rail 30, it is comparatively troublesome to install, because gear 42 need can be rotatory relatively well rail 30 to can lead to well rail 30 structure more complicated, be unfavorable for processing, preferably in a through-hole 31 has been seted up on the well rail 30, install movable carrier 70 in the through-hole 31, gear 42 install in on the movable carrier 70, thereby do not increase well rail 30's the processing degree of difficulty, more convenient the change moreover.
Further improve, because fixed rail 10 is diversified, in order to guarantee the installation that first rack 40 can be better, preferably still include first rack 50, first rack 40 sets up on first rack 50, first rack 50 joint in on the fixed rail 10.
in order to ensure that the fixed rail 10 runs more smoothly relative to the middle rail 30, the whole structure is more compact, and no shaking occurs, the improvement is further made that one side of the first rack 50 close to the middle rail 30 is provided with a ball 51, and the ball 51 is abutted against the surface of the middle rail 30.
