DETAILED DESCRIPTION

[0021] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0022] like Figures 1 to 5As shown, a teaching blackboard includes a frame 101, on which two groups of blackboard panels 102 for pushing and pulling left and right are slidably connected, and also includes a sliding guide assembly arranged on the frame 101 for guiding the sliding of the two groups of blackboard panels 102 during the pushing and pulling process, and a damping and retarding assembly is arranged on the frame 101 for damping and retarding the speed of the blackboard panels 102 during the pushing and pulling process; during the teaching use of the left-right push-pull blackboard, the sliding guide assembly and the damping and retarding assembly cooperate with each other to generate resistance to the sliding of the blackboard panels 102, and through the resistance effect, the sliding speed of the blackboard panels 102 after being pushed is effectively reduced, and the probability of the blackboard panels 102 colliding with the frame 101 after being pushed is reduced, so that the stable teaching use of the left-right push-pull blackboard is facilitated.

[0023] The sliding guide assembly includes a sliding groove 201 opened on the frame 101, a connecting block 202 is fixed on the upper end of the two blackboard bodies 102, and a plurality of sliding rods 203 are slidably connected to the two connecting blocks 202, and the sliding rods 203 are fixed on the sliding groove 201; in the process of pushing the blackboard body 102, as the blackboard body 102 moves, the connecting block 202 is driven to slide on the plurality of sliding rods 203, and through the sliding guiding effect of the connecting block 202 and the plurality of sliding rods 203, the blackboard body 102 can be pushed and slid more stably.

[0024] The damping deceleration component includes a mounting frame 301 fixed on the upper ends of two blackboard bodies 102, a mounting tube 303 is arranged on one side of the mounting frame 301, the mounting tube 303 is fixedly mounted on the upper end of the blackboard body 102 through the connecting frame 302, the interior of the mounting tube 303 is filled with damping fluid, a transmission plate 304 is arranged inside the mounting tube 303, a damping hole 305 is opened on the transmission plate 304, and a driving component for driving the transmission plate 304 is arranged inside the sliding groove 201; in the process of pushing the blackboard body 102, each transmission plate 304 is driven to move inside the mounting tube 303 through transmission, and in the process of movement, the damping fluid inside the mounting tube 303 passes through the damping holes 305 on each transmission plate 304, thereby generating a damping mechanism, thereby generating resistance to the rotation of the driving shaft 401 and the sliding of the blackboard body 102.

[0025] A plurality of transmission plates 304 are arranged inside the mounting tube 303 ; the damping and deceleration effect is improved by the plurality of transmission plates 304 .

[0026] The driving assembly includes a driving shaft 401 rotatably connected to a mounting frame 301 and a mounting cylinder 303, a plurality of transmission plates 304 are fixed in a ring array on the outside of the driving shaft 401, a driving wheel 402 is fixed at one end of the driving shaft 401, and an inclined surface 403 for driving against the driving wheel 402 is provided inside the sliding groove 201; in the process of pushing the blackboard body 102, as the blackboard body 102 moves, the mounting frame 301 and the driving shaft 401 on the mounting frame 301 are driven to move synchronously, because the driving wheel 402 is against the inclined surface 403, during the movement of the driving shaft 401 and the driving wheel 402, the driving shaft 401 is driven to rotate through the friction between the driving wheel 402 and the inclined surface 403.

[0027] The driving wheel 402 is made of rubber material; the driving wheel 402 made of rubber makes it easier for the driving wheel 402 and the inclined surface 403 to drive against each other.

[0028] During the teaching process, the left-right push-pull blackboard can be used to push the two sets of blackboard bodies 102 inside the frame 101 to the left and right, so as to facilitate flexible and convenient teaching operations.

[0029] In the process of pushing the blackboard body 102, as the blackboard body 102 moves, the connecting block 202 is driven to slide on the multiple slide bars 203, and the sliding guide effect of the connecting block 202 and the multiple slide bars 203 facilitates the blackboard body 102 to be pushed and slid more stably;

[0030] And in the process of pushing the blackboard body 102, as the blackboard body 102 moves, the mounting frame 301 and the driving shaft 401 on the mounting frame 301 are driven to move synchronously. Because the driving wheel 402 is against the inclined surface 403, during the movement of the driving shaft 401 and the driving wheel 402, the driving shaft 401 is driven to rotate through the friction between the driving wheel 402 and the inclined surface 403. During the rotation of the driving shaft 401, each transmission plate 304 is driven to move inside the mounting cylinder 303. During the movement, the damping fluid inside the mounting cylinder 303 passes through the damping holes 305 on each transmission plate 304, generating a damping mechanism, which generates resistance to the rotation of the driving shaft 401 and the sliding of the blackboard body 102. Through the resistance effect, the sliding speed of the blackboard body 102 after being pushed is effectively reduced, and the probability of the blackboard body 102 colliding with the frame 101 after being pushed is reduced, which is convenient for the stable teaching use of the left-right push-pull blackboard.
