Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
Every other embodiment obtained without creative efforts, shall fall within the protection scope of the present invention.
A kind of accounting Practical training table by hand, as shown, including desktop 1, the top surface two sides of desktop 1 are respectively fixedly connected with arc
One end of shape plate 2, the other end of arc panel 2 open up through-hole 3 before one of arc panel 2, separately towards the outside of desktop 1
The back side of one arc panel 2 is fixedly connected with the front end of inserted link 4, through-hole 3, inserted link 4 center line be each perpendicular to corresponding arc panel 2
The back side, inserted link 4 can pass through out of through-hole 3, and the periphery of inserted link 4 opens up several grooves 5, is respectively equipped with first wedge in groove 5
Shape block 6, the lozenges of the first wedge block 6 towards outside groove 5, pass through torsion between each first wedge block 6 and corresponding groove 5
Spring connects, and can match simultaneously with the rear-face contact of the corresponding arc panel 2 on another desktop 1 respectively before the first wedge block 6
It closes, attachment device is fixedly mounted in the bottom surface both side of desktop 1 respectively, and two attachment devices can be mating, and the back side of desktop 1 is opened
If sliding slot 7 that is several vertical and being parallel to each other, it is respectively equipped with sliding block 8 in sliding slot 7, sliding block 8 can be sliding along corresponding sliding slot 7 respectively
Dynamic, 1 rear of desktop is equipped with supporting plate 9, and supporting plate 9 is parallel to each other with desktop 1, and the back side of sliding block 8 connects with fixed before supporting plate 9
It connects, fanning strip 10 is hingedly installed by damping shaft in the top surface of supporting plate 9.The present invention is only used for single, in Practice Curriculum, number set
The present invention can be combined with each other, and in actual use, before desktop 1 upward, user only needs for be inserted into the inserted link 4 on a desk
In through-hole 3 on to adjacent tables, the width of the diameter of inserted link 4 and the first wedge block 6 and the diameter greater than through-hole 3, because
This, when inserted link 4 is inserted into through-hole 3, the lozenges of the first wedge block 6 is contacted with the inner wall of through-hole 3, under the effect of gravity, first
In 6 retraction groove 5 of wedge block, after the first wedge block 6 is passed through out of through-hole 3 completely, under the elastic force effect of torsional spring, first wedge
Shape block 6 is popped up out of groove 5, before the first wedge block 6 can with the rear-face contact of corresponding arc panel 2 so that
Unmanned masterpiece used time, inserted link 4 can not be extracted out of through-hole 3, this can enhance connective stability of the invention, in order to avoid unexpected feelings
Condition causes two desk separation, and the periphery of inserted link 4 and the inner wall of through-hole 3 are engaged, and inserted link 4 can rotate in through-hole 3, energy
Enough connection angles arbitrarily changed between desk, flexibility is stronger, when the wavy setting of desk in classroom, row's desk
Length is shorter, can reduce classroom area in the case where galleryful is constant, similarly, situation that can be constant in classroom area
Lower increase galleryful, Practice Curriculum be grouped when, additionally it is possible to by number set the present invention surround annular, be with six sets of present invention it is best,
One group of student surround and sits, and exchange or transmitting data, user that can be more convenient can also skid off supporting plate 9, sliding block 8 and cunning
The mutual cooperation of slot 7 can give supporting plate 9 with stable mobile support, and supporting plate 9, which skids off rear user, can be placed in file supporting plate 9
On, so as to expand the tolerant area of desktop 1, user flips up fanning strip 10, and keep fanning strip 10 concordant with supporting plate 9,
When the number set present invention surrounds annular, user can transmit file by supporting plate 9, fanning strip 10, what reduction by two sat facing each other
People transmits the difficulty of file, adjacent to one another between group member, is more convenient for observing the relevant operation of adjacent group member, to be more advantageous to use
The process and relevant operation of family understanding accountancy.
Specifically, as shown in Fig. 2, the inside of the first wedge block 6 described in the present embodiment is respectively fixedly connected with First Line
One end of rope 11, the other end of the first cotton rope 11 are respectively fixedly connected with the inside of corresponding groove 5.First cotton rope 11 can limit
The maximum angle that first wedge block 6 turns down outward, when the first wedge block 6 fold to maximum angle, the inside of the first wedge block 6
It is parallel to the inside of groove 5, when in order to avoid people extracting inserted link 4 out of corresponding through-hole 3, makes first under the action of frictional force
Wedge block 6 turn down it is excessive, in order to avoid increase inserted link 4 extract difficulty.
Specifically, as shown in figure 3, before the back side quadrangle of desktop 1 described in the present embodiment is respectively fixedly connected with table leg 12
The universal wheel 13 with lock piece is fixedly mounted in end, the rear end of table leg 12 respectively.Table leg 12 can give desktop 1 well to prop up
Support, universal wheel 13 can make the present invention easy to remove, consequently facilitating people adjust position of the invention.
Further, as shown in figure 5, blend stop 14 is fixedly mounted in two sides respectively before supporting plate 9 described in the present embodiment.Gear
It is higher than before supporting plate 9 before item 14, so as to prevent file from falling from the two sides of supporting plate 9.
Further, as shown in figure 4, attachment device described in the present embodiment is semi-cylinder shell 15, the bottom surface two of desktop 1
Semi-cylinder shell 15 is fixedly mounted in side respectively, and the opening of semi-cylinder shell 15 deviates from desktop 1, and the inside of semi-cylinder shell 15 opens up respectively
Arc through groove 16, is respectively equipped with semicircular cylinder 17 in semi-cylinder shell 15, semicircular cylinder 17 respectively with the center of corresponding semi-cylinder shell 15
Line is conllinear, and link block 18 is fixedly mounted in the periphery of semicircular cylinder 17, and link block 18 is passed through out of arc through groove 16, outside link block 18
Limit plate 19 is fixedly mounted in side respectively, and limit plate 19 can not be passed through out of arc through groove 16, and the inside of limit plate 19 and attached column
The interior side contacts of shape shell 15 cooperate, and several second wedge blocks 20, the second wedge block 20 is fixedly mounted in the inner wall of semicircular cylinder 17 respectively
It is uniformly distributed in semicircular cylinder 17, the inner wall back side of semi-cylinder shell 15 is respectively fixedly connected with the back side of half column 21, half column 21
Respectively with the centerline collineation of corresponding semi-cylinder shell 15, the periphery of half column 21 passes through torsional spring respectively and installs several third wedge shapes
Block 22, third wedge block 22 can be engaged with corresponding second wedge block 20 respectively, open up placement respectively before half column 21
Hole 23, before placement hole 23 and outside communicate with the outside world, and the back side of placement hole 23 is respectively fixedly connected with the rear end of spring 24,
