Abstract
The utility model is related to a kind of Simple student stool, belongs to field of furniture.Solve existing bench for students non-dismountable, maintenance cost is high, the short defect of service life.It includes stool surface and stool leg, and stool surface and stool leg are connected by spiral lifting bar, and described spiral lifting bar is externally provided with silk braid.The utility model is mainly used in teaching.
Description
Technical field
The utility model is related to a kind of Simple student stool, belongs to field of furniture.
Background technology
Existing pure screw type student's lifting stool is directly to connect stool surface and stool leg by screw rod, can pass through rotation
The screw rod of stool surface, freely adjusts height, using more convenient, but the external screw thread of screw rod and stool leg connect in use
The internal thread at the place of connecing easily weares and teares, and the lifting stool after thread abrasion, which loses elevating function, can only make common stool and use, what is more
Because thread abrasion causes stool surface and stool leg firmly to connect so that stool is unstable, takes and rocks, and can not use.
Because screw rod is directly connected with stool leg, if the internal thread abrasion of stool leg junction then needs replacing stool leg cost higher, if
Be screw rod external screw thread abrasion can not then repair and can only change.
Utility model content
The purpose of this utility model is to provide a kind of Simple student stool, and detachably, easy to maintenance, service life is long, into
This is low.
Described Simple student stool, including stool surface and stool leg, stool surface and stool leg are connected by spiral lifting bar, described spiral shell
Rotation elevating lever is externally provided with silk braid.
Further, described silk braid is made up of jacket and inner sleeve, and described interior be arranged with is engaged with spiral lifting bar
Screw thread.
Further, silk braid top preferably is provided with inner sleeve stopping means.
Further, described spiral lifting bar is fixedly connected with stool surface by bearing pin.
Further, it with outer casing inner wall is that not rounded is connected that described outer wall of inside race, which is,.
Further, described stool leg is no less than three.
Further, annulus is provided between described stool leg.
Further, described stool leg bottom is provided with protective case.
Further, described stool surface is ABS plastic.
Compared with prior art, the beneficial effects of the utility model are：
Spiral lifting bar of the present utility model is externally provided with the silk braid being made up of jacket and inner sleeve, therefore is worn and torn in screw thread
When can according to actual conditions change silk braid inner sleeve and overcoat, not only reduce the maintenance cost of bench for students, and greatly prolong
Its service life.The inner sleeve and overcoat of silk braid are connected using not rounded, can prevent inner sleeve from rotating in use, using stable
Property it is high.Annulus is provided between stool leg, makes each stool leg producing balanced forces, increases bearing capacity.

Embodiment
The utility model is described further below in conjunction with the accompanying drawings.
Embodiment 1
Described Simple student stool, including stool surface 1 and stool leg 8, stool surface 1 and stool leg 8 are connected by spiral lifting bar 6, institute
The spiral lifting bar 6 stated is externally provided with silk braid 10.
Embodiment 2
Described Simple student stool, including stool surface 1 and stool leg 8, stool surface 1 and stool leg 8 are connected by spiral lifting bar 6, institute
The spiral lifting bar 6 stated is externally provided with silk braid 10.Described silk braid 10 is made up of overcoat 5 and inner sleeve 4, described inner sleeve 4 be provided with
The screw thread that spiral lifting bar 6 is engaged.The described top of silk braid 10 is provided with inner sleeve stopping means 3.Spiral lifting bar 6 and stool surface 1
It is fixedly connected by bearing pin 2.It with the inwall of overcoat 5 is that not rounded is connected that the outer wall of inner sleeve 4, which is,.Described stool leg 8 is no less than three.It is described
Stool leg 8 between be provided with annulus 7.The described bottom of stool leg 8 is provided with protective case 9.The stool surface is ABS plastic.
During work, spiral lifting bar 6 is driven to rotate by rotating stool surface 1, due to inner sleeve 4 and the use not rounded connection of overcoat 5,
And silk braid 10 is provided with inner sleeve stopping means 3, stool surface 1 is firm to be raised and lowered, and when the thread abrasion of spiral lifting bar 6, is unclamped
Bearing pin 2 can pull down spiral lifting bar 6 and be changed, if being set on the thread abrasion of inner sleeve 4 then dismounting and change, stool leg 8
There are annulus 7 and protective case 9, annulus 7 makes each stool leg producing balanced forces, it is to avoid single stool leg stress is larger and damages, increase is overall
Bearing capacity, protective case 9 both can protect stool leg 8 to wear and tear, and stool leg 8 can be avoided to contact generation loud noise with ground again.
