Abstract

The invention relates to a bidirectionally-rotating folding desk. The bidirectionally-rotating folding desk comprises a desk plate, desk plate movement limiting mechanisms, hinges, desk legs, crossed supporting rods and underframes, and is mainly characterized in that grooves are formed in the left side and the right side of the desk plate (1), the desk plate (1) can be overturned front and back by sliding through the grooves and can be lifted together with the desk plate movement limiting mechanisms (2) through sliding grooves, the desk plate movement limiting mechanisms (2) are fixed to the desk legs (4) through the hinges (3), and the underframes (6) can stretch and contract together with the desk legs (4) along with stretching and contraction of the crossed supporting rods (5). The bidirectionally-rotating folding desk has the unique advantages of being simple in structure, convenient to use and practical, entering or exiting from a space in a two-dimension mode and enlarging the space, and can be used in any type of classrooms in universities, middle and primary schools, training institutions and the like.

Description

Bidirectional rotation Folding desk

Technical field

The present invention relates to a kind of teaching equipment, particularly relate to a kind of bidirectional rotation Folding desk.

Background technology

Desk is applied to classroom, and the space in known classroom always has relatively limited property.In limited space, always wish can layout many seat as far as possible, desk is designed to horizontal townhouse in the classroom of most of compact arrangements and structure is fixed, present bits number also causes the classmate's turnover being in the middle of townhouse seat very inconvenient when increasing, particularly outstanding in Zhe Dian university classroom.Existing various desk is all difficult to overcome the contradiction between tight townhouse layout and turnover conveniently.

Summary of the invention

The object of the invention is, in order to overcome existing layout and familiar lacunas, provides a kind of bidirectional rotation Folding desk, and the art of this patent can solve the inconvenient problem of the middle classmate's turnover in townhouse seat.

In order to solve the problems of the technologies described above, the present invention does further to realize by the following technical programs.

A kind of bidirectional rotation Folding desk of the present invention, comprises that table, the movable position-limit mechanism of table, hinge, table leg, cross support bar and underframe form, and described table, is characterized in that there is groove the table left and right sides, can slide by groove; The movable position-limit mechanism of described table, it is characterized in that a square has 1/4th large radius arc and a small-radius arc and a slip guide pillar in one side, and table can be overturn and pass through groove lifting in front and back; During normal operating condition, restriction table moves left and right and supports table and keeps flat; When left and right turnover state, table turn to plumbness and along guide pillar assistance for lifting; Described hinge, is characterized in that gemel connection is in table position-limit mechanism and table leg, while making table be in plumbness lowest order, can overturn left and right, and the object of turnover before and after reaching; Described table leg, it is characterized in that square column and on table leg, is provided with two four sides grooves cross support bar is connected with table leg; Described cross support bar, it is characterized in that two crossbars form a revolute pair in the middle of being supported on, and rotatably realizes different angles, realizes the flexible function of table leg; When normal operating condition and left and right turnover state, cross support bar reaches maximum angle of the crossing position; While passing in and out in front and back, cross support bar is contracted to minimum intersecting angle.Described underframe, is characterized in that table leg to be fixed on underframe, and described underframe is to be fixed on bottom surface, or does not fixedly make it flexible movement.

By overturning and make it lifting after turning to before and after table position-limit mechanism restriction table, thereby reach the object that left and right passed in and out and expanded turnover space.By hinge, realizing table can left rotation and right rotation when the plumbness lowest part, the object of turnover before and after reaching, thereby realize bidirectional rotation, solution left and right come in and go out and come in and go out problem of insufficient space only in the townhouse seat of classroom, realization passes in and out to left and right from one dimension left and right, the turnover of front and back two dimension, and increases the space while passing in and out.Both under the fixing state of underframe, guarantee the compactedness of classroom seat, realized again the convenience of turnover.Under the revocable state of underframe, can conveniently move again, table leg can be stretched along direction in opposite directions, save the space that desk takies when folding, make full use of space, classroom.

The invention has the beneficial effects as follows: bidirectional rotation Folding desk, have simple in structurely, convenient and practical, realize two dimension turnover, expand the distinct advantages in turnover space.Can use in any type of classroom, comprise university, middle and primary schools, training organization etc.

Accompanying drawing explanation

Fig. 1 is a kind of structural representation of the present invention.

Mark in figure: 1-table, the movable position-limit mechanism of 2-table, 3-hinge, 4-table leg, 5-cross support bar, 6-underframe.

Specific embodiment

As shown in Figure 1, the disclosure of the invention that this is routine a kind of bidirectional rotation Folding desk, comprise that table (1), the movable position-limit mechanism (2) of table, hinge (3), table leg (4), cross support bar (5) and underframe (6) form, be primarily characterized in that there is groove described table (1) left and right sides, can slide by groove, table (1) can be overturn and pass through chute lifting with the movable position-limit mechanism of table (2) in front and back; The movable position-limit mechanism of table (2) is fixed on table leg (4) by hinge (3); Underframe (6) can be according to use state along with the flexible of cross support bar (5) stretches together with table leg (4).

The foregoing is only specific embodiments of the invention, but architectural feature of the present invention is not limited to this, any those skilled in the art is in the field of the invention, and the variation of doing or modification are all encompassed among the scope of the claims of the present invention.

Claims

1. bidirectional rotation Folding desk, comprise that table (1), the movable position-limit mechanism (2) of table, hinge (3), table leg (4), cross support bar (5) and underframe (6) form, be primarily characterized in that there is groove described table (1) left and right sides, can slide by groove, table (1) can be overturn and pass through chute lifting with the movable position-limit mechanism of table (2) in front and back; The movable position-limit mechanism of table (2) is fixed on table leg (4) by hinge (3); Underframe (6) can be according to use state along with the flexible of cross support bar (5) stretches together with table leg (4).
