The specific embodiment
As (b), Fig. 5 and shown in Figure 6 of Fig. 1, the section of last rail 1 comprises U-shaped connecting portion 100 and respectively in the crotch portion 101 of the outwardly-bent formation of both-side ends of U-shaped connecting portion 100.The section of following rail 2 comprises U-shaped connecting portion 200 and respectively in crotch portion 201 that the both-side ends of U-shaped connecting portion 200 curves inwardly and forms, in the last rail 1 after the cooperation and the section of following rail 2, the U-shaped connecting portion 100 of last rail 1 protrudes upward between two crotch portions 201 of last rail 2, and the crotch portion 200 of rail 2 is hooked down in the crotch portion 101 of last rail 1, and the crotch portion 101 of last rail 1 and following rail 2, be placed with steel ball 8 between 201, be placed with the roller 7 of dumbbell shaped in the groove that the U-shaped connecting portion 200 of following rail 2 provides, the bottom of last rail 1 is promptly gone up the end of U-shaped connecting portion 100 of rail 1 and the connecting bridge of crotch portion 101 and is placed on this roller 7.
In embodiment illustrated in figures 1 and 2, the sliding function of slide rail is realized by last rail 1, following rail 2, roller 7, steel ball 8 and gap bar 9.Pack between last rail 1 and following rail 28 four of 7 two of rollers and steel balls respectively dispose 2 steel balls 8 on the track of the left and right sides, like this, last rail 1 just can relatively move with following rail 2.Roller 7 is done the dumbbell shaped design, goes up rail 1 and following rail 2 coefficient of sliding resistances to reduce, and reduces friction force, reaches the purpose of start steady and smooth.Gap bar 9 is used for separating steel ball 8, makes that two steel balls of each track keep rational distance in two tracks, to guarantee best lateral clearance, down suction and best sliding force.
The control of slide rail stroke realizes by the retaining point 15 of last rail 1, retaining point 10 or 13, the roller 7 of following rail 2, referring to Fig. 8 and Fig. 5, Fig. 6.When slide rail moved to end position (as Fig. 2 or position shown in Figure 1), roller 7 was run into the retaining point 10 or 13 of rail 2 down, and roller 7 stops to roll, and the retaining point 15 of last rail 1 is run into roller 7 immediately, and last rail 1 stroke stops.The slide rail stroke can be gone up rail 1 retaining point 15 by change, and realize the position of following rail 2 retainings point 10 and 13.The retaining point 15 of last rail 1, the retaining point 10 of following rail 2 designs in groups, and the retaining point 13 of following rail 2 generally is to exist with rivet or bolt, has fully satisfied the requirement of retaining point intensity.
In Fig. 5 and embodiment shown in Figure 6, the retaining point 16 of last rail 1 and the retaining point 11 of following rail 2 are stroke retaining points of steel ball 8, guarantee steel ball 8 under any state not can from rail 1 and the following rail 2 escape come out.
Fig. 3,4,7,9-11 show the lockable mechanism of slide rail of the present utility model.As shown in Figure 1, locking plate 3 is assemblied in the centre of rail 1, and the hole 24 of locking plate 3 is arranged in the hole 22 of rail 1 also by the step section 31 of axle 5, and locking plate 3 can 22 rotations around last rail hole together with axle 5.Respectively there are 4 teeth 23 locking plate 3 both sides, and 8 windows 17 are arranged on the last rail 1, and the tooth 23 of locking plate 3 can buckle in the window 17 of rail 1.The head of locking plate 3 (movable end) 25 can be stretched in last rail window 21.Returning spring 4 heads 26 are packed into and are gone up rail window 19, and buckle into rail window 20, and another head 27 of returning spring 4 colludes the gap into the head 25 of locking plate 3, make the tooth portion 23 of locking plate 3 pass window 17 and buckle into down the tooth paddy 12 of rail 2, play the latch functions of slide rail.Last rail 1 is to realize by the tooth square with respect to the adjusting step pitch of following rail 2.
As shown in figure 11, support 6 is completely fixed on the axle 5, makes also that simultaneously axle 5 can only rotate in the hole 22 of last rail 1, can not left and right sides play.Clockwise rotate and separate lock support 6, be fixed on the axle 5 owing to separate lock support 6, axle 5 clockwise rotates with respect to last rail hole 22; Axle 5 drives locking plate 3 around last rail hole 22
Clockwise rotate, locking plate 3 teeth 23 leave down the tooth paddy 12 of rail 2, and last rail 1 is removed with the locking of following rail 2.Unclamp and separate lock support 6, locking plate 3 buckles into the tooth paddy 12 of rail 2 down, slide rail locking again under returning spring 4 effects.
Under the vehicle body state, left and right sides slide rail connects synchronizing unlocking by release handle 29, upwards carries release handle 29, and the lock support 6 of separating of left and right sides slide rail is clockwise rotated simultaneously, reaches the purpose of synchronizing unlocking.
