Abstract
The utility model discloses a bidirectional rotary folding desk. The bidirectional rotary folding desk comprises a desk board 1, a desk board movable limiting mechanism 2, hinges 3, desk legs 4, intersected support rods 5, a base frame 6 and dowels 7, wherein the desk board movable limiting mechanism limits the desk board from turning forward and backward and enables the desk board to lift after turning, and thus the aims of left and right entrance and exit and increase of an entrance/exit space are achieved. The desk board can rotate leftward and rightward at the lowermost part in a vertical state by using the hinges, so that the aim of front-back entrance and exit is achieved, further the bidirectional rotation is realized, the problems that persons can enter and exit leftward and rightward in rowing seats of a classroom and the entrance/exit space is insufficient are solved, the change from one-dimensional left-right entrance/exit to two-dimensional left-right and front-back entrance/exit is realized, and the entrance/exit space is increased. The bidirectional rotary folding desk disclosed by the utility model has the unique advantages of simple structure, convenience, practicality, two-dimensional entrance/exit and increase of the entrance/exit space. The bidirectional rotary folding desk is suitable for classrooms in any form, including universities, middle and primary schools, training mechanisms and the like.
Description
Technical field
The utility model relates to a kind of office appliance, particularly relates 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, this point 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 in order to overcome existing layout and familiar lacunas, and a kind of bidirectional rotation Folding desk is provided, and the art of this patent can solve the inconvenient problem of the middle classmate's turnover in platoon seat.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: the utility model is a kind of bidirectional rotation Folding desk, comprises table, the movable position-limit mechanism of table, hinge, table leg, cross support bar, underframe.
Described table, is characterized in that there is groove the table left and right sides, can slide by groove, and table can be in three kinds of states, i.e. vertical low level left rotation and right rotation state when vertical laying state when normally use, left and right turnover passes in and out with front and back.
The movable position-limit mechanism of described table, it is characterized in that a square respectively has 1/4th large radius arc and a small-radius arc and a slip guide pillar in one side, make table before and after large radius, overturn and to pass through guide pillar lifting, the movable position-limit mechanism of a pair of table is mirror image symmetry.
Described hinge, is characterized in that hinge be connected table position-limit mechanism and table leg, can left and right upset while making table be in plumbness lowest order.
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 by pin with table leg, and four sides groove is for the activity of cross support bar and the installation of fixed part.
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 turnover in front and back, cross support bar is contracted to minimum intersecting angle.
Described underframe, it is characterized in that by fixing table leg by pin on underframe, can be in the time of tight type layout the monolateral ground that is fixed on, or bilaterally fixedly do not make it entirety movement flexibly.
By overturning and make it lifting after turning to before and after table position-limit mechanism restriction table, thereby about reaching, pass 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, ensure 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 particular advantages in turnover space.Can use in any type of classroom, comprise university, middle and primary schools, training organization etc.
Brief description of the drawings
Fig. 1 is bidirectional rotation Folding desk assembling schematic diagram.
Specific embodiment
Referring to Fig. 1, the utility model has table 1, the movable position-limit mechanism 2 of table, hinge 3, table leg 4, cross support bar 5 and underframe 6.Described bidirectional rotation Folding desk, bi-directional folded desk can be in normal use, left and right turnover, three kinds of states of front and back turnover.
In the time of normal operating condition, table 1 is blocked by the large radius arc upper end of the movable position-limit mechanism 2 of table, 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 that user needs left and right turnover, table 1 is rotated to plumbness by keeping flat along the orthodrome of the movable position-limit mechanism 2 of table under normal condition, and table groove is along sliding to lowest order under the guide pillar of spacing movable device 2.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 user needs, bidirectional rotation Folding desk passes in and out state by front and back, by rotary table plate 1 and the movable position-limit mechanism 2 of table of hinge 3, make table be in right side, cross support bar 5 is contracted to the minimum angle of the crossing, the state that two underframe merge, 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.
