Due to the adoption of the telescopiform elevating thread bushing support post or the combination with the chain wheel flexible drive combination, the utility model can be manually operated or electrically operated, and conducted the stepless elevating adjustment randomly. The utility model has the advantages of simple and reasonable structure, convenience for adjustment, safety and reliability, extensive application and strong practicality.

Description

Light stepless lift adjustment multipurpose bearing support
The utility model is that denomination of invention is dividing an application of " light stepless elevation and subsidence regulating device ", and the applying date is on May 31st, 2005, and application number is 200520058846.7
Technical field
The utility model relates to a kind of light stepless lift adjustment multipurpose support, mainly is applicable to the lift adjustment of tables and chairs, music stool, qin frame and all kinds of supports.
Background technology
Existing up-down desk and chair kind is more, structure is different.It mostly has been level greatly and has regulated, and it is not too convenient to adjust.As China Patent No. 2004200334362 disclosed a kind of spiral up-down desk and chairs, form by table body, seat support, column etc., it is characterized in that: design a screw rod, screw rod is fixed in a body, seat support lower end, suit one adjusting nut on the screw rod, the adjusting nut lower end closely contacts with being provided with through hole and the secured in parallel spandrel girder between two columns, and the top of column is provided with pin-and-hole, the both sides of table body are taken out and are had slotted eye on the wall, and bolt passes the pin-and-hole of column and is connected with slotted eye on taking out wall.It is said that this spiral up-down desk and chair can carry out lift adjustment easily, and simple in structure, cost is lower.But it is still regulated for pin-and-hole has level.
The utility model content
It is a kind of simple and reasonable, widely applicable that the purpose of this utility model is to provide, and assembling is quick, and lower-cost light stepless lift adjustment multipurpose support is to overcome weak point of the prior art.
A kind of light stepless lift adjustment multipurpose bearing support by this purpose design, comprise top support plate and bearing plate, its architectural feature is to be provided with telescopiform lifting thread bush support column between top board and the base plate, and support column is the internal and external threads cover composition that two to nine joints, size increase progressively cooperation.
Described support column be one to nine uniform; When being two and when above, be provided with flexible gear or gear drive between the support column; Be connected with handle or motor on one support column, turning handle or motor switch are to realize the stepless lift adjustment of support column.
Described flexible gear is sprocket wheel chain drive, pulley belt transmission or rope sheave rope drive; Described sprocket wheel, belt pulley or rope sheave are fixed on the support column.
The utility model can be according to user's requirement, and up-down desk and chair, music stool, qin frame, foot pedal, furniture or support and so at any time are because its adopts telescopiform lifting thread bush support column, or make up with sprocket wheel chain flexible driving, both can be manual, again can be electronic, can arbitrarily carry out stepless lift adjustment.It is simple and reasonable, and is easy to adjust, safe and reliable, widely applicable, practical.

Fig. 2 is the utility model one desk example structure schematic diagram.
Fig. 3 is the utility model one multipurpose bearing support example structure schematic diagram.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Referring to Fig. 1, a kind of music stool comprises the supporting seat board 1 on top and the V-shaped rest 4 of both sides thereof, and V-shaped rest central authorities are provided with lifting nut 5.Upper bracket 3 both sides respectively are provided with a screw rod 2, and screw rod top and lifting nut 5 sockets are provided with the sprocket chain strip transmission mechanism between two screw rods, and transmission mechanism is two layers, screw rod middle part and each one deck of bottom.The sprocket wheel 6 transmissions supporting seat board 1 at middle part, the sprocket wheel 10 transmission bottom brackets 9 of bottom.Bottom bracket 9 both sides also are provided with slide rail, slide rail is provided with plug-type foot pedal 8, the foot pedal bottom is provided with push-and-pull elongated slot 12 and telescopiform lifting thread bush support column 11, present embodiment support column 11 be about each one, the fixed bar of support column 11 passes push-and-pull elongated slot 12, drives support column 11 by foot pedal 8 and push-and-pull elongated slot 12 and moves forward and backward.Handle 7 on the rotating sprocket, lift adjustment when driving screw rod 2 and realize supporting seat boards 1 and foot pedal 8.As if two up and down that screw rod 2 are divided into socket, can distinguish transmission supporting seat board 1 and foot pedal 8.
Referring to Fig. 2, a kind of desk comprises the pillar 22 of desktop 21 and both sides thereof, is connected with crossbeam 24 below the pillar, and the two ends of crossbeam are fixed with lifting nut 23.The Corner Strapped of leg 28 has four screw rods 25, screw rod top and lifting nut 23 sockets, sprocket wheel 26 chain drives are set between four screw rods, are connected with handle 27 on the sprocket wheel, turning handle drives the lift adjustment of screw rod 25 and lifting nut 23 realization desktops 21.
Referring to Fig. 3, a kind of multipurpose bearing support, comprise top support plate 31 and bearing plate 35, be provided with telescopiform lifting thread bush support column 32 between four jiaos of top board and base plate, support column is the internal and external threads cover composition that two to nine joints, size increase progressively cooperation, and its bottom is fixed with sprocket wheel 34 chain belts, rotates the handle 33 of a side, and the sprocket wheel that drives four jiaos is to realize four jiaos support column lifting simultaneously.When inhour was rotated, the lifting thread bush raise one by one, and when turning clockwise, the lifting thread bush reduces one by one and lumps together, thereby plays the synchronization lifting effect.It can be used as piano foot-stool, seat stool, furniture bearing support etc., also more than one multipurpose bearing support can be piled up use.
