The bottom of the drawing board 10 is provided with a bracket 11, an extension bar at the bottom of the bracket 11 is connected on the pin shaft 4 through a limiting rod 5, and the bottom of the pin shaft 4 is provided with a sliding block. The lower end part of the sliding rod 3 is provided with a fan-shaped limiting block 6, the arc-shaped end part of the limiting rod 5 is matched with the middle shape of the fan-shaped limiting block 6, the fan-shaped limiting block 6 can limit the rotation angle of the limiting rod 5, and the drawing board 10 can be prevented from turning on one side and keeping a basically vertical state when moving to the side surface of the table hopper 2. The middle part of bracket 11 and the middle part of 1 one end of teaching aid show board set up a hangers 7 respectively, and hangers 7 are used for wearing to establish rope 8, and the middle part of table frame 13 top surface sets up a depressed part, sets up fixed pulley 14 in the depressed part, and fixed pulley 14 is walked around to rope 8, and fixed pulley 14 highly is not higher than the top surface of table frame 13. Set up vertical slide rail 19 on the 2 inside walls of table fill, be provided with slider 25 on the terminal surface of teaching aid show board 1, slider 25 and vertical slide rail 19 phase-match. The number of the vertical slide rails 19 in this embodiment may be multiple, or may be only the left side surface of the table bucket 2; the rope 8 is a wire rope.
The table is fought 2 and is set up a high locking mechanism, and high locking mechanism is including the pole that warp, bracing piece 18 and support frame 21, and support frame 21 sets up in the bottom surface of table fill 2, and on the right side wall of table fill 2 was worn to locate to the one end of the pole that warp, the other end of the pole that warp set up in the recess at support frame 21 top, and the one end of bracing piece 18 articulates in the bottom surface of table fill 2, and bracing piece 18 contacts with the other end of the pole that warp, and the other end of bracing piece 18 contacts with the bottom surface of teaching aid. Wherein, the deformation rod, the support rod 18 and the support frame 21 of the present embodiment are located in the same vertical plane. The deformation rod comprises a first connecting rod 23 and a second connecting rod 22, the first connecting rod 23 is inserted in the second connecting rod 22 and is in rotary connection with the second connecting rod 22 through a short shaft 24, and the length of the second connecting rod 22 is not less than that of the first connecting rod 23. The tail end of the first connecting rod 23 is provided with a positioning rod 15, the right side wall of the table bucket 2 is provided with a positioning hole 16, the positioning hole 16 is matched with the positioning rod 15, and when the positioning rod 15 is positioned in the positioning hole 16, the axis of the short shaft 24 is vertical and is positioned in a groove at the top of the support frame 21. Wherein, for limiting locating lever 15 outwards to remove at the support in-process, set the middle part of locating hole 16 to an annular ring that uses locating lever 15 as the diameter, make locating lever 15 can block and do not outwards remove in the annular ring, the locating lever clearing hole of rectangle is set to both sides, makes locating lever 15 can freely pull out when the deformation pole needs to shorten to buckle.
First connecting rod 23 and second connecting rod 22 are square bar or round bar and can rotate relatively round short axle 24 in this embodiment, in the vertical recess that is located the support frame 21 top of short axle 24, when locating lever 15 also is located locating hole 16, then can restrict the rotation of first connecting rod 23 and second connecting rod 22, thereby make first connecting rod 23 and second connecting rod 22 be located same straight line, bracing piece 18 leans on and is in the open angle maximum state and restrict its downstream at the end of second connecting rod 22, make teaching aid show board 1 be in highest position and obtain effectual support, the student can watch the model of 12 between the check on teaching aid show board 1 at this moment and draw the study. When the first link 23 is pulled out from the positioning hole 16 and the axis of the short shaft 24 is in a horizontal state, the first link 23 rotates around the short shaft 24 upwards or downwards relative to the second link 22, so that the other end of the second link 22 falls into the groove at the top of the support frame 21, the support rod 18 leans against the tail end of the second link 22 in an opening angle minimum state and limits the downward movement of the second link, and the plate making position is in a lowest position and in a stable state.
The fixed pulley type liftable drawing table of the embodiment has the following specific use process:
when the drawing table of this embodiment is changed into teaching aid show state by the drawing state, with drawing board 10 to table frame 13 riser one side removal, bracket 11 drives gag lever post 5 and rotates to drive 3 one ends of slide bar in vertical chute 20 downstream and the other end translation follow-up in horizontal chute 17, fan-shaped stopper 6 can make the turned angle scope of gag lever post 5 not too big. The drawing board 10 starts moving downward after moving horizontally to a certain extent, and as the drawing board 10 gradually moves downward, the rope 8 passes around the fixed pulley 14 to gradually transition from a slack state to a tight state, when the rope 8 is tightened, the pulling force is transmitted to the teaching aid display board 1, so that the teaching aid display board 1 moves up stably under the guiding action of the vertical slide rail 19, when the teaching aid display board 1 moves to the top end of the table bucket 2, the first connecting rod 23 and the second connecting rod 22 are rotated by 90 degrees, the short shaft 24 is vertically positioned in the groove at the top of the supporting frame 21, when the positioning rod 15 is also positioned in the positioning hole 16, the two connecting rods cannot move, the supporting rod 18 is abutted against the tail end of the second connecting rod 22, thereby make bracing piece 18 unable downstream, teaching aid show board 1 has also obtained effectual support, with drawing board 10 folding table fill 2 one side, reduces the utilization space, and steel cable 8 also is in the lax state this moment. At the moment, the student can watch the model of the grid 12 on the teaching aid display board 1 for drawing and learning.
When the drawing table of this embodiment is converted to the drawing state by teaching aid show state, earlier rotate 90 and slowly pull out first connecting rod 23, at the in-process that first connecting rod 23 and second connecting rod 22 slowly pulled out, bracing piece 18 also rotates downwards gradually, teaching aid show board 1 moves downwards gradually under the effect of gravity simultaneously, in the time of teaching aid show board 1 downstream, 8 pulling drawing boards 10 upward movements of rope, bracket 11 drives gag lever post 5 and rotates, slide bar 3 removes along with it, when first connecting rod 23 pulls out completely and can make progress or rotate downwards, teaching aid show board 1 has also fallen to the bottom, then manual top of fighting 2 with drawing board 10 pendulum, realize the conversion of drawing state.
In the sealed check 12 on teaching aid show board 1 of teaching aid model in this embodiment, be convenient for regular when not using, still can not lose, when saving and make full use of space, still realize drawing state and teaching aid show state flexible conversion down, satisfy the demand that the teacher of drawing went lesson.
The principle and the implementation mode of the present invention are explained by applying specific examples in the present specification, and the above descriptions of the examples are only used to help understanding the method and the core idea of the present invention; meanwhile, for a person skilled in the art, according to the idea of the present invention, the specific embodiments and the application range may be changed. In view of the above, the present disclosure should not be construed as limiting the invention.
