Description
Technical field
The utility model relates to a kind of jacking system, belongs to jacking system technical field.
Background technology
Nowadays, in the middle of the machine in a lot of fields and life, be applied to jacking system, more common jacking system has screw rod transmission jacking system, rack-and-gear jacking system, hydraulic-driven jacking system, and these jacking systems have some common shortcomings, rising or falling speed can not be very fast, adjustable height is inadequate, and precision is high, manufacturing cost is high, and these are all the limitation due to device itself.
Our central common tables and chairs of living, generally all fix, and can not carry out height according to the different needs of people and regulate, and this just need to have jacking system simple in structure, with low cost to meet the function of tables and chairs lifting.
Summary of the invention
The utility model provides a kind of jacking system, for solving device complex structure, problem that cost is higher.
The technical solution of the utility model is: a kind of jacking system, comprises bay-lift 1, backing block 2, base 3, connecting rod 4, intermediate bar 5, push rod 6; Wherein the below of bay-lift 1 connects one end of four connecting rods 4, two backing blocks 2 be arranged on the upper surface of base 3 and be positioned at bay-lift 1 under, base 3 fix on the ground or frame on, the other end of two connecting rods 4 connects respectively the two ends of intermediate bar 5, and the outside of intermediate bar 5 connects push rod 6.
Distance between described two backing blocks 2 is greater than the width of bay-lift 1.
On described base 3, be provided with guide rail, intermediate bar 5 is placed in guide rail.
Described push rod 6 is connected with the linear electric motors that are positioned on base, and wherein linear electric motors are the structures of start and stop simultaneously.
Rod member junction in jacking system is all chain connection.
Jacking system integral structure is symmetrical, front and back are symmetrical.
Principle of work of the present utility model is:
During rising, the linear electric motors on both sides start simultaneously, promote push rod 6 simultaneously to intermediary movements, drive two intermediate bars 5 also to intermediary movements, the lower end of such four connecting rods 4 is also drawn close to centre, and the bay-lift 1 supporting raises under the effect of connecting rod 4, while having arrived needed height, two linear electric motors stop braking simultaneously, guarantee that bay-lift 1 is steadily static simultaneously.
During decline, the linear electric motors on both sides start simultaneously, pull push rod 6 to both sides, to move respectively, driving two intermediate bars 5 also to both sides, to move, the Ye Xiang both sides, lower end of such four connecting rods 4 disperse, and the bay-lift 1 supporting declines under the effect of connecting rod 4, while having arrived needed height, two linear electric motors stop braking simultaneously, guarantee that bay-lift 1 is steadily static simultaneously.
Wherein, the distance between described two backing blocks 2 is greater than the width of bay-lift 1, so just can make intermediate bar not cross region under bay-lift.
On described base 3, be provided with guide rail, intermediate bar 5 is placed in guide rail, in order to guarantee that push rod 6 and intermediate bar 5 steadily do straight-line motion reliably.
The beneficial effects of the utility model are: simple in structure, running velocity fast and steadily, low cost of manufacture, be widely used.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is Facad structure figure of the present utility model;
Each label in figure: 1 is that bay-lift, 2 is that backing block, 3 is that base, 4 is that connecting rod, 5 is that intermediate bar, 6 is push rod.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail, but content of the present utility model is not limited to described scope.
Embodiment 1: as shown in Figure 1-2, a kind of jacking system, comprises bay-lift 1, backing block 2, base 3, connecting rod 4, intermediate bar 5, push rod 6; Wherein the below of bay-lift 1 connects one end of four connecting rods 4, two backing blocks 2 be arranged on the upper surface of base 3 and be positioned at bay-lift 1 under, base 3 fix on the ground or frame on, the other end of two connecting rods 4 connects respectively the two ends of intermediate bar 5, and the outside of intermediate bar 5 connects push rod 6.
Distance between described two backing blocks 2 is greater than the width of bay-lift 1.
On described base 3, be provided with guide rail, intermediate bar 5 is placed in guide rail.
Described push rod 6 is connected with the linear electric motors that are positioned on base, and wherein linear electric motors are the structures of start and stop simultaneously.
Rod member junction in jacking system is all chain connection.
Jacking system integral structure is symmetrical, front and back are symmetrical.
