A kind of Rotatable desk-chair
Technical field
What the present invention relates to is a kind of desk and chair.
Background technology
In the teaching method in modern times, teaching pattern changes from teacher-centered to student-oriented model, and classroom teaching student resource is discussed link and is seized of increasing ratio.But the desk and chair in present classroom is all unidirectional setting, listens to the teacher in the classroom that can only meet student, be unsuitable for carrying out seminar, easily cause classroom discipline chaotic.
Although existing much about the improvement project of desk, the most complex structure of these schemes, is difficult to apply.
Summary of the invention
The object of the present invention is to provide a kind of structure simple, be suitable for Rotatable desk-chair easily.
The object of the present invention is achieved like this:
Comprise fixing seat, fixing desk, also comprise rotatable one tables and chairs; The table frame of fixing desk forms by fixing back prop, fixing front standing pillar and four limit square bases, and fixing back prop and fixing front standing pillar are arranged on pedestal, and described fixing front standing pillar is cylindrical; Described rotatable one tables and chairs comprise table, support and rotary seat, the support of rotatable one tables and chairs comprises the connecting rod rotating front standing pillar, rotate back prop and be connected to rotation front standing pillar and rotate between back prop, table is arranged on and rotates on front standing pillar, rotary seat is arranged on and rotates on back prop, and described rotation back prop is cylindrical; Rotate back prop to be sleeved on fixing front standing pillar.
The present invention can also comprise:
The connecting rod of 1, the support of rotatable one tables and chairs is provided with stopping means.
2, the fixing table of desk and the table of rotatable one tables and chairs are formed by upper and lower two tables.
3, rotate between back prop and fixing front standing pillar and be provided with bearing.
4, there is concave arc breach at the edge, upper table side of fixing desk, and the edge, upper table side of rotatable one tables and chairs is convex arc shape.
In technical scheme of the present invention: fixing seat selects, and platoon chair comprises two seats and a support, and support supports two chairs, and the support side of being door shape, lower end is connected to the ground by pedestal.The table frame bag of fixing desk crosses upper and lower two tables and a support.Fixing table frame serves plate one lateral edges two concave arc breach.Under fixing table frame, table and support are connected to form a storage layer.Fixing table frame support is made up of top end holder, two square pillars, two cylindrical columns and four limit square bases, and square pillar and cylindrical columns are arranged on pedestal.Four limit square bases are provided with stopping means.Rotatable one tables and chairs comprise upper and lower table, support and a seat.It is convex arc shape that rotatable one tables and chairs serve plate one lateral edges.Rotatable one tables and chairs support comprises top end holder, a square pillar and a cylindrical columns.On rotatable one tables and chairs support, cylindrical columns is sleeved on the cylindrical columns of fixing table frame, and centre bearing is separated by.
The effect that said structure feature produces is mainly reflected in: two rotary type tables and chairs devices, in fixed table frame, can carry out the rotation of 180 ° respectively around side, becomes independently one tables and chairs after rotation separately.Rotary type tables and chairs novel structure, easy to use, plastic simplicity is attractive in appearance, solve the problem that traditional tables and chairs lack flexibility, be applicable to give lessons the modern teaching methods combined with student classroom discussion with traditional hearing, also can be used for the place such as academic forum and intra-company's meeting simultaneously.

Detailed description of the invention
Embodiments of the present invention are described in detail below in conjunction with accompanying drawing:
Composition graphs 1-3, Rotatable desk-chair mainly comprises four parts: fixed platoon chair 1, fixed table frame 2, two identical rotary type one tables and chairs 3 and 4.Fixed platoon chair 1 comprises support 6, two seats 5 and pedestal 7; Fixed table frame 2 comprises square pillar 8, pedestal 9, circular pillar 18, top end holder 15, lower table 14, upper table 16 and stopping means 17; Rotary type one tables and chairs comprise circular pillar 10, square pillar 11, seat 5, lower table 12 and upper table 13.
Support 6 supports two identical seats 5, and is connected to the ground by pedestal 7, forms fixed platoon chair.
Square pillar 8 is placed on pedestal and with upper end support and is connected to support upper table 16, and lower table 14 is connected to form storage layer with pillar 8, and circular pillar 18 is placed on pedestal to support rotary type one tables and chairs 3 and 4.
Rotary type one tables and chairs are connected with fixed table frame 2 by circular pillar 10, and circular pillar 10 is sleeved on circular pillar 18, and bearing is equipped with to ensure mutual rotation between the two in centre.
Stopping means 17 can ensure that rotary type one tables and chairs 3 rotate within the scope of 180 ° of position as shown in Figure 2 to rotary type one tables and chairs 3 in position as shown in Figure 1 left, and rotation direction is reversible.Rotary type one tables and chairs 4 rotating manner is in like manner in rotary type one tables and chairs 3.
During use, if student carries out colloquy, just rotary one tables and chairs 3 and 4 can be gone to position as shown in fig. 1, now student sits face-to-face mutually; If rotary one tables and chairs 3 and 4 are gone to position as shown in Figure 2, now student is in the same way in the face of teacher, just can collective listen teacher to give lessons.
