[0021] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings:
[0022] like Figure 2~Figure 4 As shown, the adjustable movable baffle is installed at the tail of the screen box 1. The cross section of the tail of the screen box 1 is in the shape of "[". The baffle installed at the tail of the screen box 1 is movable and can be adjusted. The purpose of the adjustment is to change the size of the tail outlet of the screen box 1, and at the same time, it can conveniently control the opening and closing of the tail outlet of the screen box 1, so as to facilitate the adjustment of the screen plate in the screen box 1.
[0023] The adjustable movable baffle includes a connecting plate 5, a flip plate 6, a fixed plate 7 and an adjustment hole group. The connecting plate 5 is a flat plate body, and the connecting plate 5 is adjustable front and back on the bottom surface of the tail of the screen box 1, that is, the connecting plate 5 can be adjusted front and back, and its installation position can be changed.
[0024] In order to realize the installation of the connecting plate 5, an adjusting long hole 8 is opened on the connecting plate 5. The number of the adjusting long holes 8 is two and is arranged at intervals along the length direction of the connecting plate 5. The length direction of the adjusting long hole 8 is perpendicular to the length direction of the connecting plate 5. At the same time, the connecting plate 5 is also connected to the bottom surface of the tail of the screen box 1 by an adjusting bolt 9. The adjusting bolt 9 passes through the adjusting long hole 8 and is threadedly connected to the bottom surface of the tail of the screen box 1. Each adjusting long hole 8 is penetrated by an adjusting bolt 9.
[0025] After tightening the adjusting bolt 9, the adjusting bolt 9 presses and fixes the connecting plate 5, thereby installing and fixing the connecting plate 5. Once the adjusting bolt 9 is loosened, the connecting plate 5 is in a loose and adjustable state. At this time, the connecting plate 5 can be slid forward and backward, and then the adjusting bolt 9 moves in the adjusting slot 8. After the connecting plate 5 adjusts its position, tighten the adjusting bolt 9 again to fix the connecting plate 5 and the tail of the screen box 1. The bottom surface of the tail of the screen box 1 can support the connecting plate 5, so that the connecting plate 5 is not suspended in the air.
[0026] The connecting plate 5 is hinged forward with a flip plate 6, which is bent into a "〉" shape. The connecting plate 5 and the flip plate 6 are of equal length and consistent with the width of the tail outlet of the screen box 1. Both ends of the connecting plate 5 and the flip plate 6 are bent upward to form flanges, so that the cross-sections of the connecting plate 5 and the flip plate 6 are both "[" shaped.
[0027] The connection plate 5 and the flip plate 6 are hinged when installed. A plurality of hinge plates 10 are arranged between the connection plate 5 and the flip plate 6 to hinge and realize the relative rotation of the connection plate 5 and the flip plate 6. On the basis of the adjustable installation of the connection plate 5 and the bottom surface of the tail of the screen box 1, only the flip plate 6 can rotate. The flip plate 6 is suspended, that is, the bottom of the flip plate 6 is not supported by the bottom surface of the tail of the screen box 1, so the flip plate 6 can freely rotate a certain angle.
[0028] In order to realize the rotation and fixation of the flip plate 6, a fixing plate 7 is provided on both sides of the flip plate 6. The fixing plate 7 is bent into an "L" shape and has holes. When the flip plate 6 rotates, the two fixing plates 7 can be driven to rotate together. At the same time, adjustment hole groups are opened on both side walls of the rear of the screen box 1, and the adjustment hole groups on the same side correspond to the fixing plates 7.
[0029] The adjustment hole group includes a plurality of adjustment holes 11, wherein the number of adjustment holes 11 in each adjustment hole group is three, and the three adjustment holes 11 are arranged obliquely up and down. A pin 12 is provided between the corresponding fixed plate 7 and any adjustment hole 11 in the adjustment hole group, and the tail of the screen box 1 and the fixed plate 7 can be connected by the pin 12, so that the fixed state of the flip plate 6 can be achieved.
[0030] The principle of the utility model is: the connection plate 5 can be installed at the tail of the screen box 1 through two adjusting bolts 9, and the flip plate 6 can be installed at the tail of the screen box 1 through two pins 12, so that the installation of the entire movable baffle and the screen box 1 is realized. When the screen plate in the screen box 1 needs to be adjusted, the two pins 12 are removed, and then the flip plate 6 is freely dropped and flipped, and flipped to below the bottom surface of the tail of the screen box 1. At this time, the tail outlet of the screen box 1 is opened, and the screen plate can be adjusted.
[0031] When the size of the tail outlet of the screen box 1 needs to be adjusted, first loosen the adjusting bolt 9 to make the connecting plate 5 movable. Then remove the two pins 12, move the position of the flip plate 6, and when the fixed plates 7 on both sides of the flip plate 6 correspond to the adjusting holes 11 at the top, insert the pins 12 between the adjusting holes 11 and the fixed plates 7 to fix the flip plate 6. When the flip plate 6 moves, the connecting plate 5 will also move passively. After the flip plate 6 is fixed, tighten the adjusting bolt 9 again to fix the connecting plate 5. At this time, the movable baffle is at the highest point, and the tail outlet of the screen box 1 is the smallest.
[0032] If you want the tail outlet of the screen box 1 to be the largest, you need to make the movable baffle at the lowest position to ensure that the movable baffle blocks the tail outlet of the screen box 1 to the minimum. At this time, the flip plate 6 is connected and installed with the adjustment hole 11 at the bottom through the pin 12. It should be noted that when the flip plate 6 is connected and installed with any adjustment hole 11, the adjustment bolt 9 must be loosened in advance to ensure that the connecting plate 5 is in a movable state, because the flip plate 6 and the connecting plate 5 are linked, and the flip plate 6 will drive the connecting plate 5 to move together when it moves.
[0033] The embodiments described above are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made based on the structures, features and principles described in the patent scope of the present invention should be included in the patent application scope of the present invention.
