DETAILED DESCRIPTION

[0049] The following is combined with Figure 1-4 This application is described in further detail.

[0050] The present application embodiment discloses a lacquer painting screen. Figure 1 The lacquer painting screen includes a mounting frame 1, which includes a mounting frame 11 and a mounting block 12. The mounting frame 11 is a "mouth"-shaped structure, and a plurality of mounting blocks 12 are evenly spaced and fixed at the bottom of the mounting frame 11. When in use, the mounting blocks 12 abut against the ground to support the mounting frame 11.

[0051] See also Figure 1 and Figure 2The middle position of the mounting frame 11 is the mounting cavity 13, and the two side openings of the mounting cavity 13 are square structures. The mounting frame 11 is fixedly connected with a support block 14, and the support block 14 is located at the position of the cavity opening on one side of the mounting cavity 13. There are multiple support blocks 14 and they are respectively located at the four corners of the cavity opening of the mounting cavity 13. The lacquer painting screen also includes a drawing board 2, and the end surface area of ​​the drawing board 2 is smaller than the cavity opening area of ​​the mounting cavity 13. During installation, the drawing board 2 slides into the mounting cavity 13 from the cavity opening on the side away from the support block 14 until the end surface of the drawing board 2 abuts against the support block 14.

[0052] The mounting frame 11 is rotatably connected with a hinge shaft 15, and there are two hinge shafts 15 that are symmetrically arranged. The hinge shafts 15 are located at the cavity opening of the mounting cavity 13 away from the support block 14 and are respectively adjacent to the vertical cavity wall. The mounting frame 11 is provided with clamping blocks 3 corresponding to the support blocks 14 one by one, and the support blocks 14 are located at the four corners of the cavity opening of the mounting cavity 13 away from the support block 14. The clamping blocks 3 are rotatably connected to the hinge shaft 15.

[0053] The mounting frame 11 is provided with an elastic driving member, which is a driving torsion spring 16, which is sleeved on the hinge shaft 15, and one end of the driving torsion spring 16 abuts against the mounting frame 11, and the other end abuts against the clamping block 3. When the driving torsion spring 16 is elastically released, it pushes the clamping block 3 to flip away from the support block 14, and at this time, the drawing board 2 can slide out of the mounting cavity 13 in the direction away from the support block 14.

[0054] See also Figure 2 and Figure 3 , the mounting frame 11 is provided with a fixing assembly, and the fixing assembly includes a connecting plate 41, a fixing column 4, a fixing rope 42, an extrusion block 43 and a fixing spring 44. A connecting groove is formed on the side of the clamping block 3 close to the slide board, and the connecting plate 41 slides in the connecting groove. The connecting plate 41 is fixedly connected with a slider 411 of a "T"-shaped structure, and a sliding groove 31 of a "T"-shaped structure is formed on the groove wall of the connecting groove facing the drawing board 2, and the slider 411 is slidably connected to the sliding groove 31. When the clamping block 3 is flipped to be parallel to the support block 14, the clamping block 3 and the connecting plate 41 are respectively abutted against the side of the slide board facing away from the support block 14. At this time, the clamping block 3 and the support block 14 cooperate to clamp the drawing board 2 to fix the drawing board 2.

[0055] See also Figure 4 A linkage member is provided between the upper and lower connecting plates 41, and the linkage member is a linkage bar 5, and the linkage bar 5 is respectively fixedly connected to the upper and lower connecting plates 41. When one of the connecting plates 41 is slid, the linkage bar 5 drives the other connecting plate 41 in the vertical direction to slide.

[0056] See also Figure 1 and Figure 2The fixing column 4 is fixed on the side of the vertical cavity wall of the connecting plate 41 close to the installation cavity 13. The fixing column 4 is perpendicular to the hinge shaft 15. The fixing column 4 is a cylindrical structure, and the side of the fixing column 4 away from the connecting plate 41 is formed with an arc surface structure. The vertical side walls on opposite sides of the installation cavity 13 are respectively formed with fixing grooves 131. There are multiple fixing grooves 131 and they correspond to the fixing columns 4 one by one. When the clamping block 3 abuts against the side of the slide board facing away from the support block 14, the fixing column 4 is aligned with the fixing groove 131, and the connecting plate 41 is slid toward the fixing groove 131, so that the fixing column 4 is inserted into the fixing groove 131. At this time, the clamping block 3 enters a fixed state, and the driving torsion spring 16 enters a compressed state. When the fixing column 4 is out of the fixing groove 131, the driving torsion spring 16 is released, pushing the clamping block 3 to flip in the direction away from the drawing board 2.

[0057] See also Figure 2 and Figure 3 The extrusion block 43 is a "T" shaped structure. The extrusion block 43 slides in the slide slot 31, and the extrusion block 43 is located on the side of the slider 411 away from the fixed slot 131. The fixing spring 44 corresponds to the connecting plate 41 one by one and is installed in the slide slot 31. One end of the fixing spring 44 is fixed to the side of the slider 411 away from the fixed slot 131, and the other end is fixed to the extrusion block 43. The fixing rope 42 is slidably arranged in the clamping block 3, one end of the fixing rope 42 is fixed to the outer peripheral side of the hinge shaft 15, and the other end is fixed to the extrusion block 43.

[0058] When the clamping block 3 flips toward the supporting block 14, the fixing rope 42 is wound around the outer peripheral side of the hinge shaft 15, and the fixing rope 42 pulls the extrusion block 43 to slide toward the fixing groove 131; when the fixing column 4 is not aligned with the fixing groove 131, the fixing column 4 slides on the vertical cavity wall of the installation cavity 13, and the extrusion block 43 squeezes the fixing spring 44 until the fixing column 4 is aligned with the fixing groove 131, and the fixing spring 44 is elastically released, pushing the slider 411 to slide, driving the connecting plate 41 to move closer to the fixing groove 131, so that the fixing column 4 is inserted into the fixing groove 131, and the clamping block 3 is fixed. When the connecting plate 41 slides in the direction away from the fixing groove 131, the fixing column 4 is separated from the fixing groove 131, and the slider 411 squeezes the fixing spring 44, driving the torsion spring 16 (driving the torsion spring 16 in Figure 1 ) pushes the clamping block 3 away from the drawing board 2, so that the fixing rope 42 is loosened, and the fixing spring 44 pushes the squeezing block 43 away from the slider 411.

[0059] See also Figure 2 and Figure 4A receiving groove 132 is formed on the bottom wall of the installation cavity 13, and the receiving groove 132 corresponds to one of the connecting plates 41 located below. The installation frame 11 is provided with a stopper 6 of an "inverted L" structure, and the stopper 6 slides up and down in the receiving groove 132. The side wall of the stopper 6 close to the support block 14 abuts against the end face of the drawing board 2 away from the support block 14. At this time, the stopper 6 preliminarily fixes the drawing board 2, which makes it easier to install and fix the drawing board 2.

[0060] The mounting frame 11 is provided with an elastic power member, which is a power spring 7, and the power spring 7 is installed in the receiving groove 132. The top of the power spring 7 abuts against the bottom of the stopper 6, and the bottom of the power spring 7 abuts against the bottom groove wall of the receiving groove 132. The stopper 6 is inclined to form a push surface 61 on the side facing away from the drawing board 2. When the power spring 7 is elastically released, the stopper 6 is pushed to slide out of the receiving groove 132 until the push surface 61 is outside the receiving groove 132.

[0061] An inverted L-shaped retaining groove 412 is formed on one side of the connecting plate 41 close to the drawing board 2. When the fixing column 4 is aligned with the fixing groove 131, the connecting plate 41 slides toward the fixing groove 131, so that the fixing column 4 is inserted into the fixing groove 131. At this time, the retaining block 6 slides into the retaining groove 412, and the connecting plate 41 is restricted by the retaining block 6, thereby restricting the clamping block 3 from flipping away from the drawing board 2, thereby further improving the stability of the clamping block 3 and the supporting block 14 in clamping the drawing board 2.

[0062] The implementation principle of a lacquer painting screen in the embodiment of the present application is:

[0063] When the drawing board 2 is replaced, the linkage bars 5 on both sides are slid to drive the corresponding connecting plates 41 to slide, so that the fixing column 4 is disengaged from the fixing groove 131. At this time, the torsion spring 16 is driven to push the clamping block 3 to flip in the direction away from the drawing board 2 until the clamping block 3 is flipped out of the installation cavity 13. Then, the stopper 6 is pressed to make the stopper 6 completely slide into the receiving groove 132, and then the drawing board 2 is pushed from the side of the support block 14 and in the direction away from the support block 14, so that the drawing board 2 is disengaged from the installation cavity 13. Finally, the replaced drawing board 2 can be slid into the installation cavity 13 until the stopper 6 abuts against the drawing board 2, and then the clamping blocks 3 on both sides are flipped to abut against the drawing board 2. At this time, the fixing column 4 is inserted into the fixing groove 131, so that the clamping block 3 enters a fixed state, and the installation and fixation of the drawing board 2 are achieved.

[0064] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
