[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides the following technical solution: a flexible spray masking fixture:

[0028] Example 1: To address the problem that existing masking plates 1 lack an automatic material ejection mechanism for disassembly, requiring manual removal from the spraying platform later, which is inconvenient and impractical, the following solution is disclosed: A masking plate 1 with two through holes 2, wherein the two through holes 2 are located on the top sides of the masking plate 1, and the bottom of the masking plate 1 is open; limiting blocks 3 are slidably installed at both ends of the masking plate 1, and the two limiting blocks 3 are symmetrically arranged about the vertical center line of the masking plate 1, with the outer sides of the two limiting blocks 3 extending through to the masking plate 1. The outer sides of both ends; a slot 10 is provided on the top front side of the shielding plate 1, and a top rod 4 is provided on the outer side of the slot 10. The top rod 4 is provided on the top front side of the shielding plate 1. Movable seats 6 are slidably installed on both sides of the front end of the shielding plate 1. The two movable seats 6 have the same structure, and the front ends of the two movable seats 6 are rotatably connected to support rods 5 through movable shafts. At the same time, the front ends of the two support rods 5 are rotatably connected to the top rod 4 through movable shafts. The two support rods 5 are inclined. A first compression spring 7 is provided on the inner side of the front end of the shielding plate 1, and the two ends of the first compression spring 7 are connected to the movable seats 6.

[0029] like Figures 1-6 As shown, after the masking plate 1 is installed on the spraying platform, the spraying platform will squeeze the top rod 4 to retract and move. At this time, the top rod 4 will drive the two support rods 5 to squeeze the two moving seats 6 on the inner side of the top of the masking plate 1 through the movable shaft, so that the top rod 4 is stored in the inner side of the slot 10. During the disassembly and separation of the masking plate 1 from the spraying platform, the first compression spring 7 will elastically reset the two moving seats 6 through its own elastic force. At this time, the two reset moving seats 6 will drive the two support rods 5 to squeeze the top rod 4 to move elastically through the movable shaft, so that the top rod 4 is squeezed against the spraying platform, thereby squeezing the material onto the masking plate 1. There is no need to manually remove the masking plate 1 from the spraying platform, making the operation more time-saving and labor-saving.

[0030] Different from example one, the shielding plate 1 can be quickly positioned at the spraying platform to avoid the phenomenon of loosening and falling off of the shielding plate 1 during the spraying process, and the stability is better, and the shielding plate 1 is disclosed:

[0031] The two limiting blocks 3 are in an inclined shape, the shielding plate 1 is connected with the second extrusion springs 9 at both ends in the inside, the structures of the two second extrusion springs 9 are the same, and one end of the two second extrusion springs 9 is connected with the limiting block 3, the front ends of the two push rods 8 are installed with the limiting block 3, and the front ends of the two push rods 8 extend to the outside of the front end of the shielding plate 1.

[0032] As shown in Figures 1-4 When the shielding plate 1 is positioned and installed, the shielding plate 1 is only placed at the spraying platform for extrusion and descent, at this time, the limiting blocks 3 arranged at both sides of the shielding plate 1 will be moved by the extrusion of the spraying platform, so that the two limiting blocks 3 are moved to both ends in the inside of the shielding plate 1, and then the two second extrusion springs 9 can automatically pop out the two limiting blocks 3 in an inclined shape to the inside of the spraying platform by the elastic force of the second extrusion springs 9, so as to realize the positioning and fixing of the shielding plate 1, avoid the phenomenon of loosening and falling off of the shielding plate 1 during the spraying process, and the stability is better, and the two push rods 8 can be pushed again to drive the two limiting blocks 3 to move, so that the shielding plate 1 is separated from the spraying platform, and then the shielding plate 1 can be conveniently and quickly disassembled and replaced, and the operation is more time-saving and labor-saving.

[0033] The above is the working process of the whole device, and the contents not described in detail in the specification all belong to the prior art known by the professional technical personnel in the field.
