Abstract
A kind of lifting regulating mechanism of dining chair, comprise second support, with first support that second support is slidingly connected mutually, be provided with locking mechanism between described second support and first support.Described locking mechanism comprises out at least one spacing hole on the sidewall of second support, is inserted in the dead bolt in the spacing hole, and dead bolt is connected by dead bolt turning cylinder phase pivot with first support.One end of dead bolt has the spacing operative end surface inconsistent with the hole wall of spacing hole, and the other end of dead bolt is connected with hauling rope.Affect hauling rope to make the spacing operative end surface of dead bolt leave the hole wall of spacing hole, locking mechanism promptly is unlocked, and dining chair just can be made lift adjustment.
Description
Technical field
The utility model relates to the lifting regulating mechanism of a kind of children dinning chair, particularly children dinning chair.
Background technology
In the prior art, children dinning chair supports child seat pocket and service plate by pair of supporting, and bracing frame is fixing non-telescoping support usually.But the children's height of use dining chair and the height of dining table are different, and also just different to the requirement for height of service plate, same bracing frame often is difficult to satisfy multiple demand, and this makes troubles just for many users.
Summary of the invention
The utility model purpose provides a kind of lifting regulating mechanism of dining chair, and it highly can be regulated.
For achieving the above object, the technical solution adopted in the utility model is: a kind of lifting regulating mechanism of dining chair, comprise second support, with first support that described second support is connected slidably, be provided with locking mechanism between described second support and described first support.Described locking mechanism comprises out at least one spacing hole on the sidewall of described second support, is inserted in the dead bolt in the described spacing hole, and described dead bolt is connected by dead bolt turning cylinder phase pivot with described first support.One end of described dead bolt has the spacing operative end surface inconsistent with the hole wall of described spacing hole, and the other end of described dead bolt is connected with hauling rope.
Because technique scheme utilization, the utility model compared with prior art has following advantage: first support is connected slidably with second support, be inserted in locking first support and second support in the spacing hole with dead bolt, and dead bolt is connected with the first support phase pivot, and by hauling rope control dead bolt, affect hauling rope to make the spacing operative end surface of dead bolt leave the hole wall of spacing hole, dining chair just can be made the different needs of lift adjustment with the people that adapts to different heights, and operation is also simple and convenient.
Description of drawings
Accompanying drawing 1 is for having the front view of children dinning chair of the present utility model;
Accompanying drawing 2 is the enlarged drawing of the A part in the accompanying drawing 1;
Wherein: 1, first support; 2, second support; 3, dead bolt; 4, hauling rope; 5, hauling rope head; 6, spacing operative end surface; 7, dead bolt turning cylinder; 8, stage clip positioning boss; 9, stage clip; 10, spacing hole; 11, through hole;
The specific embodiment
Specifically set forth below in conjunction with each accompanying drawing.
Referring to accompanying drawing 1, a kind of lifting regulating mechanism of dining chair, comprise second support 2, with first support 1 that described second support 2 is connected slidably, be provided with locking mechanism between described second support 2 and described first support 1.Referring to accompanying drawing 2, described first support 1 is inserted in the inner chamber of described second support 2 slidably.Described locking mechanism comprises out at least one spacing hole 10 on the sidewall of described second support 2, is inserted in the dead bolt 3 in the described spacing hole 10.Described dead bolt 3 is connected by dead bolt turning cylinder 7 phase pivots with described first support 1, is provided with stage clip 9 between described dead bolt 3 and described first support 1.Described dead bolt 3 is arranged in the inner chamber of described first support 1, has through hole 11 on the sidewall of described first support 1, and described dead bolt 3 passes described through hole 11.One end of described dead bolt 3 has the spacing operative end surface 6 inconsistent with the hole wall of described spacing hole 10, and the other end of described dead bolt 3 is connected with hauling rope 4.
Usually on the outer surface of the support of dining chair, also be provided with the hauling rope button that is connected with hauling rope 4, pulling hauling rope button, hauling rope 4 just spurs dead bolt 3, thereby the spacing operative end surface 6 of dead bolt 3 is left spacing hole 10, locking mechanism just is unlocked, the relative position of first support 1 and second support 2 can be regulated, thereby the height of dining chair can be regulated.Regulate after the height of dining chair, unclamp the hauling rope button, dead bolt 3 is subjected to the active force of stage clip 9 and is inserted in the spacing hole 10, the hole wall of the automatic conflict spacing hole 10 of its spacing operative end surface 6 meetings, locking mechanism is just locked, and dining chair just can stably be in required height.
Referring to accompanying drawing 2, the cross section of described spacing operative end surface 6 is a circular arc.Distance between described dead bolt turning cylinder 7 and the described spacing operative end surface 6 is R, and the distance between the junction that is connected dead bolt 3 on described dead bolt turning cylinder 7 and the described hauling rope 4 is a, and the length of described R is less than the length of a.According to lever principle as can be known, because the length of R is less than the length of a, the pulling force of pulling hauling rope 4 is just smaller with respect to the power of the spacing operative end surface 6 conflict spacing holes 10 of dead bolt 3, so the such link position of the shape of design dead bolt 3 and dead bolt 3 and hauling rope 4, it is just lighter, laborsaving to pull out dead bolt 3 from spacing hole 10.
