Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example.

Example 1

Referring to Figures 1-3, a drawing board frame includes a base 1, a mounting groove 2, a two-way screw rod 3, two connecting blocks 4, a guide mechanism, a first drawing board 7, a second drawing board 8 and a rotation adjustment mechanism 9, Mounting groove 2 is provided on the upper surface of base 1, two-way screw rod 3 is rotationally connected in the inside of mounting groove 2, and two connecting blocks 4 are all threaded on the two-way screw rod 3, and between two connecting blocks 4 are oppositely arranged, two The lower end of the connecting block 4 is arranged inside the mounting groove 2 through a guiding mechanism. The guiding mechanism includes two sliders 5 and a guide rod 6. The two sliders 5 are fixedly connected to the lower ends of the two connecting blocks 4 respectively, and the guiding rod 6 is fixedly connected On the inner side wall of the installation groove 2 , and the two sliding blocks 5 are slidably sleeved on the guide rod 6 .

The lower end of the first drawing board 7 is hinged on the upper end of one of the connecting blocks 4, the lower end of the second drawing board 8 is hinged on the upper end of the other connecting block 4, and the upper end of the first drawing board 7 and the second drawing board 8 is hinged. One drawing board 7 and the second drawing board 8 are oppositely arranged, and the rotation adjusting mechanism 9 is arranged on one side of the base 1 , and the rotation adjusting mechanism 9 is connected with one end of the two-way screw rod 3 .

Example 2

1-3, as another preferred embodiment of the present utility model, the difference from Embodiment 1 is that the rotation adjustment mechanism 9 includes a groove 91, a threaded rod 92 and a turntable 93, and the groove 91 is set on a side of the base 1. side, the threaded rod 92 runs through the groove 91, one end of the threaded rod 92 is fixedly connected to one end of the two-way screw 3, and the other end of the threaded rod 92 extends to one side of the base 1, and the turntable 93 is fixedly connected to the threaded rod 92 extends to one end on one side of the base 1 , the threaded rod 92 is provided with a fastening mechanism, the fastening mechanism is a nut 94 , and the nut 94 is threadedly connected to the threaded rod 92 .

working principle:

First, loosen the nut 94 to turn the turntable 93. The turntable 93 will drive the threaded rod 92 to rotate, and the threaded rod 92 will drive the two-way screw 3 to rotate. During the rotation of the two-way screw 3, and the two sliders 5 and the guide rod 6 under the guiding and limiting action, can make the opposite horizontal linear movement between the two connecting blocks 4, then, by adjusting the forward and reverse rotation of the turntable 93, the two connecting blocks can be adjusted 4, during the process of relative movement between the two connecting blocks 4, the first drawing board 7 and the second drawing board 8 will rotate upwards and tilt simultaneously, and the first drawing board 7 and the second drawing board The drawing boards 8 are set relative to each other.
