Detailed Description
Referring to fig. 2 and 3, in the sliding member structure of the chair back adjusting device of the present utility model, one end of the chair back adjusting device 2 is locked under the seat cushion A1 of the chair a, and the other end of the chair back adjusting device 2 is locked by the chair back A2; the chair back adjusting device 2 is provided with a supporting plate 3, an adjusting piece group 4 arranged on the supporting plate 3 and a sliding piece 5 sliding on the supporting plate 3.
As shown in fig. 2 and 3, the lower end of the supporting plate 3 is locked under the seat cushion A1, more specifically, the lower end of the supporting plate 3 is locked on the control adjusting device A3 for controlling the pitch angle and the height of the chair by the first screw assembly S.
As shown in fig. 2 and 3, the adjusting member set 4 includes a fixing plate 41 and an adjusting plate 42 that can slide up and down on the fixing plate 41; the adjusting component set 4 is locked on the supporting plate 3 by the second screw component S1 at the lower end of the fixing plate 41, so that the adjusting component set 4 obtains a positioning effect on the supporting plate 3; the adjusting plate 42 of the adjusting member set 4 is slid on the fixing plate 41; the fixing plate 41 has a positioning protruding column 411, the adjusting plate 42 is provided with a plurality of positioning slots 421, the positioning protruding column 411 can be separated from the positioning slots 421, so that the adjusting plate 42 slides in the vertical axial direction on the fixing plate 41 by taking the fixing plate 41 as a sliding guide shaft; the positioning protrusion 411 can be inserted into the positioning slot 421 to position the adjusting plate 42 after the fixing plate 41 slides along the vertical axis; furthermore, the adjusting member set 4 is separated from or embedded into the positioning slot 421 by the positioning protrusion 411, so that the adjusting plate 42 is adjusted in height on the fixing plate 41 in the vertical axial direction and the positioning effect after the height adjustment.
As shown in fig. 2, 3 and 4, the sliding member 5 has a through hole 51, and the upper end of the sliding member 51 is locked and connected with the adjusting plate 42 of the adjusting member set 4 by a third screw assembly S2, so that the sliding member 5 can be adjusted in height along the vertical axis of the fixing plate 41 in synchronization with the adjusting plate 42 of the adjusting member set 4, and the positioning effect after the height adjustment; a plurality of locking holes 52 are arranged on two sides of the sliding piece 5, and the locking holes 52 are used for locking the chair back A2; the sliding piece 5 is sleeved on the supporting plate 3 in a sliding manner by the through hole 51, more specifically, the sliding piece 5 is sleeved on the supporting plate 3 and also covers the sliding sleeve of the adjusting piece set 4, so that the two inner sides of the through hole 51 of the sliding piece 5 are slightly contacted with the supporting plate 3, and therefore, the sliding piece 5 has a stable sliding effect when sliding vertically and axially along the supporting plate 3; therefore, when the height of the adjusting plate 42 of the adjusting member set 4 is adjusted in the vertical direction on the fixing plate 41, the sliding member 5 is driven to slide in the vertical direction on the supporting plate 3, so as to adjust the height and position of the chair back A2.
