Description
Technical field
The utility model relates to desk, particularly relates to a kind of bidirectional rotation Folding desk.
Background technology
The space in classroom is relatively limited, 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, this is particularly outstanding in university classroom.Existing various desk is all difficult to overcome the contradiction between tight townhouse layout and turnover conveniently.
Summary of the invention
The purpose of this utility model is to be all difficult to overcome tight townhouse layout and the contradiction of turnover between convenient for existing various desks, and a kind of bidirectional rotation Folding desk of the problem such as inconvenience that can solve student's turnover in the middle of townhouse seat is provided.
The utility model is provided with table, the movable position-limit mechanism of left table, the movable position-limit mechanism of right board, left hinge, right hinge, table leg, cross support bar, underframe and pin;
The described table left and right sides is provided with groove, and table slides by groove; The movable position-limit mechanism of described left table and the movable position-limit mechanism of right board are mirror image symmetry, the movable position-limit mechanism of left table and the movable position-limit mechanism of right board are square plate, in the one side of square plate, be provided with 1 large radius arc, 1 small-radius arc and 1 slip guide pillar, table can overturn and pass through groove lifting before and after large radius arc; When normal operating condition, restriction table moves left and right and supports table and keeps flat; In the time of left and right turnover state, table turn to plumbness and along slip guide pillar assistance for lifting; Described left hinge the be connected movable position-limit mechanism of left table and table leg, described right hinge the be connected movable position-limit mechanism of right board and table leg, can left and right upset while making table be in plumbness lowest order, the object of turnover before and after reaching; Described table leg is provided with 2 four sides grooves makes cross support bar be connected by pin with table leg; Described cross support bar is in the middle of two crossbars are supported on, to form a revolute pair, 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 turnover in front and back, cross support bar is contracted to minimum intersecting angle; Table leg is fixed by a pin on underframe, described underframe can be in the time of tight type layout the monolateral ground that is fixed on, or bilateral fixedly not make it entirety mobile flexibly.
It is foursquare column that described table leg can adopt cross section.
The utility model is overturn and is made it lifting after turning to by table position-limit mechanism restriction table front and back, thereby about reaching, passes in and out and expand the object in turnover space.Realizing table by hinge can left rotation and right rotation when the plumbness lowest part, the object of turnover before and after reaching, thereby realize bidirectional rotation, solving in the townhouse seat of classroom left and right only comes in and goes out and comes in and goes out the problem of insufficient space, 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 turnover.Both under the monolateral 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, flexible topology.
The beneficial effects of the utility model are: bidirectional rotation Folding desk, have simple in structurely, convenient and practical, and 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.

The specific embodiment
Referring to Fig. 1～11, the utility model embodiment is provided with table 1, the movable position-limit mechanism 21 of left table, the movable position-limit mechanism 22 of right board, left hinge 31, right hinge 32, table leg 4, cross support bar 5, underframe 6 and pin 7.
Described table 1 left and right sides is provided with groove, and table 1 slides by groove; The movable position-limit mechanism 21 of described left table and the movable position-limit mechanism 22 of right board are mirror image symmetry, the movable position-limit mechanism 21 of left table and the movable position-limit mechanism 22 of right board are square plate, in the one side of square plate, be provided with 1 large radius arc, 1 small-radius arc and 1 slip guide pillar, table 1 can overturn and pass through groove lifting before and after large radius arc; When normal operating condition, restriction table 1 moves left and right and supports table 1 and keeps flat; In the time of left and right turnover state, table 1 turn to plumbness and along slip guide pillar assistance for lifting; Described left hinge 31 the be connected movable position-limit mechanism 21 of left table and table leg 4, described right hinge 32 the be connected movable position-limit mechanism 22 of right board and table leg 4, can left and right upset while making table 1 be in plumbness lowest order, the object of turnover before and after reaching; Described table leg 4 is provided with 2 four sides grooves makes cross support bar 5 be connected by pin 7 with table leg 4; Described cross support bar 5 is in the middle of two crossbars are supported on, to form a revolute pair, 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 turnover in front and back, cross support bar is contracted to minimum intersecting angle; Table leg 4 is fixed on underframe 6 by pin 7, described underframe 6 can be in the time of tight type layout the monolateral ground that is fixed on, or bilateral fixedly not make it entirety mobile flexibly.
It is foursquare column that described table leg 4 adopts cross section.
The utility model can be in normal use, left and right turnover, front and back turnover and three kinds of states.
In the time of normal operating condition, as shown in Figure 1, table 1 is blocked by the large radius arc upper end on the movable position-limit mechanism 21 of left table and the movable position-limit mechanism 22 of right board, is flat condition.Cross support bar 5 is retractable to the maximum angle of the crossing, and a pair of table leg 4 and a pair of underframe 6 move to maximum spacing thereupon, now for the study of normally attending class.
In the time of the turnover of needs left and right, as shown in Figure 2, table 1 is rotated to plumbness by keeping flat along the large radius arc of the movable position-limit mechanism 21 of left table and the movable position-limit mechanism 22 of right board under normal condition, and the groove of table 1 is along sliding to lowest order under the slip guide pillar of the movable position-limit mechanism 21 of left table and the movable position-limit mechanism 22 of right board.Now, reduce table 1 and take up space, turnover space, left and right increases, and left and right turnover is convenient.Cross support bar 5 keeps the maximum angle of the crossing under normal condition, and a pair of table leg 4 and a pair of underframe 6 keep maximum spacing.
While turnover before and after needs, as shown in Figure 3, the utility model passes in and out state by front and back, by left hinge 31 and right hinge 32 rotary table plates 1 and the movable position-limit mechanism 21 of left table and the movable position-limit mechanism 22 of right board, make table 1 be in right side, cross support bar 5 is contracted to the minimum angle of the crossing, the state that two underframe 6 merge, and a pair of table leg 4 and a pair of underframe 6 keep minimum spacing.Thereby turnover before and after realizing, reaches two dimension turnover object.
