Detailed description of the invention:
Attached drawing 1 is the utility model one example structure schematic diagram；
Attached drawing 2 is Fig. 1 embodiment partial structurtes enlarged diagram.
Specific embodiment:
Make furtherly below with reference to technical effect of the attached drawing to the design of the utility model, specific structure and generation
It is bright, to be fully understood from the purpose of this utility model, feature and effect.
Refering to fig. 1, shown in 2, the utility model is suitable for computer desk, dining table, work in relation to a kind of lifting-positioning device
Table top, article bear the assemblings such as face, keyboard support use.The device has bearing seat 1, and bearing seat 1 is connected and fixed by crane 2
Seat 3, crane 2 is made of two strut cross-articulations, wherein the upper end of the first strut 21 and bearing seat 1 are articulated and connected, and this
The lower end of one strut 21 is then assembled in fixing seat 3 as slideable.It is held by slideable be assembled in the upper end of second strut 22
It carries on seat 1, and the lower end of second strut 22 and fixing seat 3 are articulated and connected.It is drawn by elastomer 4 lower end of first strut 21
It holds and the lower extreme direction towards the second strut 22 is drawn close, elastomer 4 as shown in the figure is the extension spring in interior plant fixing seat 3.Gu
Reservation 3 is equipped with booster 6, which drives hinge joint of second strut 22 relative to its lower end to rotate.Second strut
22 upper end is equipped with fastening screw 5, and the location hole 11 being spaced apart on the fastening screw 5 insertion bearing seat 1 cooperates lifting with this
Frame 2 realizes the above adjustable height positioning of two-stage；Whereby, bearing seat 1 rises or falls and can be located in by the realization of fastening screw 5
In corresponding height, reach height adjustment use.When specifically used, elastomer 4 pulls and supports the lower end of the first strut 21 towards the second strut
22 lower extreme direction is drawn close, and booster 6 drives hinge joint of second strut 22 relative to its lower end to rotate, and is achieved in the first strut
21 and second strut 22 respective end sliding, support bearing seat 1 is opposite to be risen, and is at this moment inserted on bearing seat 1 by fastening screw 5 again
Location hole 11, that is, can reach bearing seat 1 and be located in corresponding height, realize height adjustment use.Structure designs advantages of simple,
It is easy to operate.And when needing to rise or fall bearing seat 1 again, releasing fastening screw 5 positions, and elastomer 4 and the effect of booster 6 make
Bearing seat 1 rises, or firmly pushes bearing seat 1, overcomes the active force of elastomer 4 and booster 6, can decline bearing seat
1.Lifting positioning is firm, realizes the multistage lifting positioning of both forward and reverse directions.
Fig. 1, shown in 2, in the present embodiment, the fastening screw 5 exits location hole 11 by the driving of bracing wire 7, decontrols bracing wire 7
Then fastening screw 5 is automatically inserted into location hole 11(structure on bearing seat 1 by increasing reset spring i.e. on fastening screw 5
Can, do not show in figure).Further, as shown in the figure, the bracing wire 7 of the present embodiment is divided to two sections of designs, the pulling end of first segment bracing wire 7A
It is connected to one end of swing rod 8, the driving end of the other end connection second segment bracing wire 7B of swing rod 8, and the pulling of second segment bracing wire 7B
End is then connected on knob 9, and knob 9 is assembled on bearing seat 1.The middle section of the swing rod 8 is hinged on a horizontal bar, realizes pendulum
8 both ends of bar are opposite to deflect swing (the horizontal bar can be bearing seat 1 or the cross bar of crane 2).By operation knob 9, the is pulled
Two sections of bracing wire 7B drive 8 respective end beat of swing rod by second segment bracing wire 7B, and the other end of swing rod 8 then acts on first segment bracing wire 7A
Pulling end, be achieved in first segment bracing wire 7A pull fastening screw 5.
Fig. 1, shown in 2, in the present embodiment, the knob 9 be the flip structure body being hinged on bearing seat 1, is shaking hands 9
It is equipped with hook 91, which mounts the hanging hole 31 in fixing seat 3 when bearing seat 1 falls gathering, reaches bearing seat 1 whereby
Fall the form of firm gathering.In figure, crane 2 divides for left and right settings, thus is equipped with left and right fastening screw 5, in fixing seat 3
It is correspondingly provided with the knob 9 of left and right.Operation left and right knob 9 realizes that crane 2 realizes the above adjustable height positioning of two-stage, operation side
Just, comfortably.Hook 91 on knob 9 mounts the hanging hole 31 in fixing seat 3 when bearing seat 1 falls gathering, i.e. bearing seat 1 declines
When, knob 9 follows decline, and when bearing seat 1 declines completely, the hook 91 on knob 9 can mount the hanging hole in fixing seat 3
31, reaching prevents bearing seat 1 from bouncing automatically, and use is safer；And when unlocking, knob 9 need to be only pulled, it is easy to operate.
Fig. 1, shown in 2, in the present embodiment, the booster 6 is torsional spring, and structure is simple, prevent from making and assemble, investment at
This is low.The slidingtype group of limit sliding chutes cooperation the first strut 21 and the second strut 22 is offered in fixing seat 3 and bearing seat 1 respectively
Dress.Slidingtype assembling can be selected using the structural bodies such as sliding block, idler wheel, specific structure according to actual needs, be slided as long as meeting
