Abstract
A table-platform-lifting tea table adopting a ratchet mechanism to locate relates to the technology field of furniture, in particular to a table-platform-lifting tea table that adopts a ratchet mechanism to locate and can be fixed at different heights in the process of table-platform lifting. The technical proposal is that a lifting mechanism comprising an upper bearing board, a lower bearing board and a connecting bar connected between a base and a table, the upper connecting bar is connected with the lower bearing board through the ratchet mechanism and an extension spring is connected with the end of the lower connecting bar. The utility model can achieve a fixed connection between the table and the base through a ratchet mechanism and guarantee a user to lift the table-platform safely and easily.
Description
The utility model relates to the furniture technical field, and refering in particular to a kind of tables can be at tables' Liftable type tea table of the fixing employing ratchet mechanism location of differing heights in the lifting process.
In reception room or meeting room, tea table is the indispensable furniture of part.Its volume is small and exquisite, occupy little space, but must give play to very big effect, so people is more fastidious to the requirement of its function.In general, tea table all is formed by fixedly connecting by pedestal and tables, the manufacturer usually just drops into great effort and money and goes exploitation, research on its shape, pattern, color, material and size, and few people go to do structural exploration, thereby cause the single phenomenon of 26S Proteasome Structure and Function of tea table.Such as, general tea table is manufactured into after the product, and its big or small height just can not be adjusted and change, and this can not adjust the height of tea table according to the needs of self height with regard to causing the people who uses tea table, usually causes user's sticky feeling.
The purpose of this utility model is to provide a kind of tables can be at tables' Liftable type tea table of the fixing employing ratchet mechanism location of differing heights in the lifting process.
The utility model is achieved by the following technical solution: drawer is fixedly connected on the pedestal, the upper bearing plate of fixedlying connected with tables, the lower support plate of fixedlying connected and constituted tables' lifting mechanism with the hinged connecting rod of upper bearing plate and lower support plate respectively with pedestal, the lower end of lower link is connected with extension spring, the other end of extension spring is connected the end of lower support plate, the lower end of last connecting rod is provided with ratchet mechanism, ratchet mechanism comprises the ratchet of fixedlying connected with last connecting rod, the unsteady cam that is connected on the ratchet shaft, be hinged on ratchet and flexible member on the pedestal, one end of flexible member is fixedly connected on the pedestal, and its other end is pressed on the ratchet.
Because the utility model adopts lifting mechanism, make tables relatively pedestal move up and down, thereby can realize regulating the height of tea table table top; Again owing to ratchet mechanism has been adopted in the junction of connecting rod in the lifting mechanism of the present utility model and lower support plate, engagement by ratchet and ratchet, can realize with the integrated connecting rod of ratchet in the location of diverse location, thereby realize at various height the tables location; The extension spring that is fixedly connected on lower link lower end and the lower support plate can play the power-assisted effect when user's lifting tables, thereby guarantee that the user easily finishes lifting tables' action, and extension spring can guarantee tables' pedestal that can not clash in the decline process, because the pulling force maximum that extension spring is subjected to when tables drop down onto on the pedestal, correspondingly its tensile elongation is also the longest.
Below in conjunction with accompanying drawing the utility model is further specified:
Accompanying drawing 1 is the utility model user mode figure
Accompanying drawing 2 is the utility model three-dimensional exploded view
Accompanying drawing 3 is the utility model lifting mechanism enlarged drawing
See Fig. 1,2,3, the utility model comprises pedestal 1, tables 2, drawer 3, upper bearing plate 4, lower support plate 5, connecting rod 6, extension spring 7 and ratchet mechanism 8, drawer 3 is fixedly connected on the pedestal 1, the upper bearing plate 4 of fixedlying connected, the lower support plate 5 of fixedlying connected and the lifting mechanism that has constituted tables 2 respectively with the hinged connecting rod 6 of upper bearing plate 4 and lower support plate 5 with pedestal 1 with tables 2, its two ends at pedestal 1 respectively have one; The lower end of lower link 62 is connected with extension spring 7, the other end of extension spring 7 is connected the end of lower support plate 5, the lower end of last connecting rod 61 is provided with ratchet mechanism 8, ratchet mechanism 8 comprises the ratchet 81 of fixedlying connected with last connecting rod 61, floating is connected cam 83 on the ratchet shaft 82, is hinged on ratchet 84 and flexible member 85 on the pedestal 1, ratchet 81 and last connecting rod 61 are one-body molded, one end of flexible member 85 is fixedly connected on the pedestal 1, its other end is pressed on the ratchet 84, and flexible member 85 is a torsionspring.
When using the utility model, needs according to the user, the user pulls tables 2 and makes it relative pedestal 1 and move up and down, in this process, the back side of the ratchet of ratchet 81 compresses the ratchet of ratchet 84, and overcome the thrust of flexible member 85, make the ratchet disengaging of ratchet 84 and the engagement of the ratchet of ratchet 81, thereby make with last connecting rod 61 integrated ratchets 81 and turn to desired position around ratchet shaft 82, tables 2 are when falling, because the ratchet of ratchet 84 is buckled between the ratchet of ratchet 81 under the thrust effect of torsionspring 85, thereby realize at various height tables 2 location; After table top 2 is lifted to the extreme higher position, the end of last connecting rod 61 (its end is provided with projection) promotes a unsteady side that is connected the cam 83 on the ratchet shaft 82, make it overcome the thrust of flexible member 85, and the ratchet that makes ratchet 84 acts on the center of the direction of the active force on the cam 83 by cam 83, thereby ratchet 84 is temporarily fixed, can pull tables 2 this moment makes its whereabouts, when tables 2 contact with pedestal 1, the opposite side of the end actuating cam 83 of connecting rod 61, thereby ratchet 84 is meshed again with ratchet 85, therefore, the utility model can be according to the fixing tables 2 of desired height, can guarantee that again tables 2 fall after rise to pedestal 1; Again owing on the lower end of lower link 62 and lower support plate 5, be fixedly connected with extension spring 7, it can play the power-assisted effect when user's lifting tables 2, again because the pulling force maximum that extension spring 7 is subjected to when tables 2 drop down onto on the pedestal 1, correspondingly its tensile elongation is also the longest, therefore extension spring can 7 enough guarantees tables 2 pedestal 1 that can not clash in the decline process, thereby both can realize regulating the height of tea table table top, can guarantee that again the user easily and safely finishes lifting tables 2 action; Owing on pedestal 1, be fixedly connected with drawer 3, be convenient to article and place again, can satisfy space-saving needs, help keeping the clean and tidy of tea table table top again.
