Description
Technical field
The utility model relates to a kind of locking device for swivel chair, belongs to the optimisation technique of swivel chair.
Background technology
Current swivel chair, major part all adopts gas support to carry out height and regulates, and with the requirement of the user of satisfied different height, and can do 360 degree of rotations.But in some specific occasion, time such as, when moving swivel chair, by swivel chair feet, all wish that chair no longer rotates.
Therefore, need to find a kind of device that swivel chair is no longer rotated when needed.
Summary of the invention
The purpose of this utility model is: provide a kind of device that swivel chair is no longer rotated when needed.
The technical solution of the utility model is: swivel chair locking device, and swivel chair mainly comprises gas support seat 1, motion bar 2, seat cushion mount pad 3, and seat cushion is placed on seat cushion mount pad, motion bar 2 one end is down inserted in gas support seat 1 endoporus upward, motion bar 2 one end is upward fixed on seat cushion mount pad 3, swivel chair locking device mainly comprises the annular retaining ring 4 with a keeper 41, keeper is the longitudinal opening be located in retaining ring, retaining ring is fixed on gas support seat end face upward away from the lower surface of the part of keeper, the lug with corresponding screw that shape is outwardly identical with size is provided with at the two ends of keeper, a bolt 42 passes the screw of two lugs, rotate spiral shell inspection forward or backwards, just lock or unclamp two lugs, when locking two lugs, lug sticks together, the reduced width of keeper, retaining ring 4 banding motion bar 2, motion bar 2 can not be rotated, when unclamping two lugs, separately, the width change of keeper is returned to original state greatly to lug, and under the effect of external force, motion bar can rotate.
Described retaining ring has and is not connected on gas support seat end face upward higher than the end face weld down of 2/3rds.
The length of two ends distance two lugs of welding portion is identical.
Beneficial effect
1, on gas support seat end face upward, be provided with the retaining ring of keeper, by with spiral shell inspection locking or to unclamp in retaining ring two relative lugs, make retaining ring from banding outside to inside or unclamp motion bar, realizing making motion bar can not rotate the function maybe can rotated.
Accompanying drawing explanation
Fig. 1 is partial cutaway schematic of the present utility model;
Fig. 2 is the partial enlarged drawing of Fig. 1;
Fig. 3 is the A-A figure of Fig. 1.
Detailed description of the invention
As shown in Figure 1, Figure 2 and Figure 3, swivel chair locking device, swivel chair mainly comprises gas support seat 1, motion bar 2, seat cushion mount pad 3, and seat cushion is placed on seat cushion mount pad; Motion bar 2 one end is down inserted in gas support seat 1 endoporus upward, and motion bar 2 one end is upward fixed on seat cushion mount pad 3.In routine use, by the height of gas support seat adjusting seat.
Rotate for preventing motion bar, the annular retaining ring 4 seat end face being upward provided with a keeper 41 is supportted at gas, keeper is the longitudinal opening be located in retaining ring, retaining ring is fixed on gas support seat end face upward away from the lower surface of the part of keeper, the lug with corresponding screw that shape is outwardly identical with size is provided with at the two ends of keeper, a bolt 42 passes the screw of two lugs, rotate spiral shell inspection forward or backwards, just lock or unclamp two lugs, when locking two lugs, lug sticks together, the reduced width of keeper, retaining ring 4 banding motion bar 2, motion bar 2 can not be rotated, when unclamping two lugs, separately, the width change of keeper is returned to original state greatly to lug, and under the effect of external force, motion bar can rotate.
Described retaining ring has and is not connected on gas support seat end face upward higher than the end face weld down of 2/3rds, when retaining ring is in releasing orientation, two lugs separately, motion bar can freely move up and down or rotate, when retaining ring is from banding motion bar outside to inside, motion bar just can not freely rotate again.
The length of two ends distance two lugs of welding portion is identical.
Above-described embodiment is only used to interpretation purposes of the present utility model; and be not to restriction of the present utility model, those skilled in the art, in essential scope of the present utility model; make a variety of changes or substitute, also should belong to protection category of the present utility model.
