Abstract
The utility model discloses a lifting device for a swivel chair chassis, comprising a movable block shell (1), a movable block inner plate (2), taper pipes (3) and a gas spring (4), wherein the top of the gas spring (4) is provided with a gas spring switch button (11); the movable block inner plate (2) is provided with a straight slot; pressure lever fixing plates (8) are fixed at the two sides of the straight slot; a lifting pressure lever (5) is hinged between the two pressure lever fixing plates (8); the upper end of the lifting pressure lever (5) corresponds to the gas spring switch button (11) and the lower end thereof is connected with a stay wire (9); the movable block shell (1) corresponding to the stay wire (9) is provided with an opening sleeve (10); a return spring (7) is arranged between the lifting pressure lever (5) and the opening sleeve (10); and the stay wire (9) passes through the return spring (7) and the opening sleeve (10). After adopting the structure, the lifting device has the advantages of simple and compact structure, flexible and convenient operation, low manufacturing difficulty, low production cost, reliable use and the like.
Description
Technical field
The utility model relates to a kind of swivel chair chassis, the wire-control lifting device on particularly a kind of swivel chair chassis.
Background technology
Along with the progress of development of science and technology and society, people's living standard and office conditions are constantly improved, and the demand of swivel chair is also increasing.The swivel chair chassis is a vitals that is assemblied in below the swivel chair seat cushion, and it has can allow multiple functions such as the synchronous reclining of swivel chair lifting, seat cushion and backrest, ratio reclining.The lowering or hoisting gear on present high-grade swivel chair chassis adopts the line traffic control mode to control the lifting that air spring is realized swivel chair more, though the line traffic control mode has various ways, and the complex structure that has, manufacture difficulty is big, the cost height; Though what have is simple in structure, poor reliability.For this reason, many manufacturers and knowledgeable people have carried out R and D, do not solve the problems referred to above but have than reasonable approach as yet so far.
Summary of the invention
For the above-mentioned disadvantage that the lowering or hoisting gear that overcomes existing swivel chair chassis exists, the purpose of this utility model provides a kind of simple and compact for structure, flexible and convenient operation, manufacture difficulty is little, cost is low, the lowering or hoisting gear on service-strong swivel chair chassis.
The technical scheme that its technical problem that solves the utility model adopts, it comprises the movable block shell, the movable block inner panel, Taper Pipe, air spring, the movable block shell is fixedlyed connected with Taper Pipe with the movable block inner panel, air spring is installed in the Taper Pipe, the top of described air spring is provided with the air spring shift knob, the movable block inner panel is provided with straight trough, be fixed with the depression bar fixed head in the both sides of straight trough, between two depression bar fixed heads, be hinged with the lifting depression bar, the upper end of lifting depression bar is corresponding with the air spring shift knob, the lower end of lifting depression bar is connected with backguy, be provided with opening sleeve with the corresponding movable block shell of backguy, be provided with back-moving spring between lifting depression bar and opening sleeve, backguy is passed back-moving spring and is connected with the direction switch of peripheral hardware with opening sleeve.
Described lifting depression bar is L-shaped.
After adopting said structure, the utility model has following advantage and effect: the one, when needs are adjusted the swivel chair height, the operation direction switch, direction switch pulling backguy also drives the rotation of lifting depression bar, lifting depression bar upper end moves downward depresses the air spring shift knob, make air spring be in released state, can adjust the height of swivel chair; The 2nd, simple in structure, flexible and convenient operation is used reliably, and difficulty of processing is little, and production cost is low.
Description of drawings
Fig. 1 is the structural representation of the utility model lock-out state.
Fig. 2 is the structural representation of the utility model released state.
The specific embodiment
Illustrated in figures 1 and 2, specific embodiments for the lowering or hoisting gear on the utility model swivel chair chassis, it comprises movable block shell 1, movable block inner panel 2, Taper Pipe 3, air spring 4, movable block shell 1 is fixedlyed connected with Taper Pipe 3 with movable block inner panel 2, air spring 4 is installed in the Taper Pipe 3, the top of described air spring 4 is provided with air spring shift knob 11, movable block inner panel 2 is provided with straight trough, be fixed with depression bar fixed head 8 in the both sides of straight trough, between two depression bar fixed heads 8, be hinged with lifting depression bar 5 by pivot pin 6, lifting depression bar 5 is L-shaped, the upper end of lifting depression bar 5 is corresponding with air spring shift knob 11, the lower end of lifting depression bar 5 is connected with backguy 9, be provided with opening sleeve 10 with backguy 9 corresponding movable block shells 1, be provided with back-moving spring 7 between lifting depression bar 5 and opening sleeve 10, backguy 9 is passed back-moving spring 7 and is connected with the direction switch of peripheral hardware with opening sleeve 10.
During the utility model locking, as shown in Figure 1, lifting depression bar 5 is under the elastic force effect of back-moving spring 7, and the upper end of lifting depression bar 5 is lifting state, and air spring shift knob 11 cuts out, and air spring 4 is in the lock state, and the swivel chair height is fixed.
During the utility model released state, as shown in Figure 2, operation direction switch (not marking among the figure), the lower end of backguy 9 pulling lifting depression bars 5, lifting depression bar 5 is behind the elastic force that overcomes back-moving spring 7 gentle snap switch buttons 11, the upper end moves downward and opens air spring shift knob 11, and air spring 4 is in released state, can adjust the height of swivel chair.
