[0041] Referring to Figure 1 In an embodiment of the present application, a wall painting simulation test block 10 drawing auxiliary mold is disclosed, which comprises a bottom plate 20, a cover plate 30 and a grid division assembly 40. The bottom plate 20 is provided with a placement area 21 for placing the wall painting simulation test block 10. The cover plate 30 is hinged on the bottom plate 20. The cover plate 30 is hollowed out at a position opposite to the placement area 21 to form a drawing area 31. The grid division assembly 40 is arranged on the cover plate 30. The grid division assembly 40 extends to the drawing area 31 to partially cover the wall painting simulation test block 10 to divide a plurality of drawing areas.

[0042] The wall painting simulation test block 10 drawing auxiliary mold disclosed in the embodiment is used by first separating the bottom plate 20 and the cover plate 30, placing the wall painting simulation test block 10 to be drawn in the placement area 21, and then covering the cover plate 30. At this time, the grid division assembly 40 is suspended in the drawing area 31 and located directly above the wall painting simulation test block 10. When the manufacturer looks from top to bottom, only part of the wall painting simulation test block 10 can be seen through the drawing area 31, that is, a plurality of drawing areas are exposed. The manufacturer can accurately draw in the drawing area by taking the edge of the grid division assembly 40 as a reference, thereby improving the accuracy of test block drawing.

[0043] Specifically, after each test block is made, the cover plate 30 is picked up, a new mural simulation test block 10 is placed in the same position, and the cover plate 30 is covered after that, the same drawing area on the new mural simulation test block 10 can be drawn, thereby improving the consistency of the test block drawing.

[0044] It can be seen that, in the embodiment, the bottom plate 20 and the cover plate 30 are arranged in a split type, which facilitates replacement of the mural simulation test block 10, thereby improving the feasibility of batch operation. At the same time, the cover plate 30 supports the grid division assembly 40, so that the grid division assembly 40 is only aligned with the mural simulation test block 10 in the up-down direction and does not contact the mural simulation test block 10, thereby not affecting the drawing operation and avoiding damage to the surface of the mural simulation test block 10.

[0045] Specifically, according to actual use needs, the placement area 21 disclosed in the embodiment can be arranged in various shapes such as square, triangle, and circle for different shapes of the mural simulation test block 10; and the grid division assembly 40 can be provided with square, triangular, and circular mesh holes, thereby facilitating drawing of color blocks or color strips of various shapes and being conducive to adaptation to various use scenarios.

[0046] As shown in Figure 1 As another embodiment of the present application, the cover plate 30 is provided with a guide groove 32 parallel to the edge of the drawing area 31; the grid division assembly 40 includes a sliding seat 41 and a strip-shaped dividing piece 42, the sliding seat 41 is slidably arranged in the guide groove 32; the sliding seat 41 is provided with at least two, and at least two of the sliding seats 41 are oppositely arranged; the strip-shaped dividing piece 42 is arranged in the drawing area 31; the strip-shaped dividing piece 42 is arranged between the oppositely arranged two sliding seats 41 and used for covering the mural simulation test block 10.

[0047] The strip-shaped dividing piece 42 disclosed in the embodiment is used as a reference object and at least partially overlaps the mural simulation test block 10 to shield the mural simulation test block 10, thereby drawing only part of the surface. When the strip-shaped dividing piece 42 is provided with multiple strip-shaped dividing pieces 42, a grid format structure can be formed, thereby dividing the surface of the mural simulation test block 10 into multiple areas to obtain multiple drawing areas.

[0048] For example, multiple strip-shaped dividing pieces 42 can be arranged in a cross shape to form a square grid, a square mesh hole is formed between adjacent two strip-shaped dividing pieces 42, and correspondingly, multiple square drawing areas can be formed on the mural simulation test block 10 to facilitate drawing of different color blocks.

[0049] Specifically, in this embodiment, the guide groove 32 is provided along the edge of the drawing area 31. The shape of the drawing area 31 can be set to be the same as the shape of the placement area 21. For example, when the placement area 21 is square, the shape of the drawing area 31 is also square, and the guide groove 32 is set as a straight line along the edge of the drawing area 31; when the placement area 21 is circular, the shape of the drawing area 31 is also circular, and the guide groove 32 can be set as an arc along the edge of the drawing area 31.

[0050] However, in this embodiment, regardless of the shape of the guide groove 32, at least a pair of sliding seats 41 are provided opposite to each other, and the strip dividing piece 42 between the two sliding seats 41 passes through the drawing area 31 and covers the mural simulation test block 10, thus serving to divide the drawing area.

[0051] Specifically, as another embodiment of this application, the side of the guide groove 32 facing away from the drawing area 31 is provided as an inclined surface 33, and a scale 34 is provided on the inclined surface 33, which is arranged parallel to the guide groove 32. In this embodiment, the thickness of the base plate 20 and the cover plate 30 is relatively small. When the mold is placed on the workbench, the maker can observe it from above or at an angle. Therefore, the inclined surface 33 is provided so that the scale 34 can be seen intuitively. The maker can easily determine the position of the strip segment 42 based on the scale 34, thereby determining the width of the drawing area, so as to further improve the accuracy and consistency of the drawing operation.

[0052] In another embodiment of this invention, several sliding seats 41 and several strip-shaped dividing pieces 42 can be provided, so that they are arranged in an alternating manner to divide multiple drawing areas, which can increase the number of drawing areas on the mural simulation test block 10 and improve the utilization rate of a single mural simulation test block 10.

[0053] like Figure 1 and Figure 2 As shown, in another embodiment of this application, the sliding seat 41 is disclosed to include a snap-fit ​​portion 411 and a plug-in portion 412. The snap-fit ​​portion 411 has a slot 4111 on its side wall, which is used to snap into the side wall of the guide groove 32. The plug-in portion 412 is provided on the snap-fit ​​portion 411. The plug-in portion 412 has a plug hole 4121 extending toward the center point of the drawing area 31, which is used to plug into the strip segment 42.

[0054] In this embodiment, the guide groove 32 can be configured to penetrate the cover plate 30. The snap-fit ​​part 411 is I-shaped and snaps into the guide groove 32. The slots 4111 on both sides of the snap-fit ​​part 411 are inserted into the side walls of the guide groove 32. By connecting the snap-fit ​​part 411 to the guide groove 32, the sliding seat 41 is constrained to the cover plate 30, and the sliding seat 41 will not fall off when sliding along the guide groove 32. In this embodiment, the strip-shaped dividing piece 42 can pass through the insertion hole 4121 and be tied to the insertion part 412 to keep it fixed.

[0055] For example Figure 1 As shown in another embodiment of this application, a plurality of reference ribs 22 are staggered within the placement area 21, and the reference ribs 22 are arranged parallel to the strip-shaped dividing member 42. The reference ribs 22 disclosed in this embodiment can be either protruding ribs or recessed grooves. The mural simulation test block 10 contacts the base plate 20; by setting the reference ribs 22, the surface roughness of the base plate 20 is increased, thereby improving the stability of the mural simulation test block 10 during the painting process.

[0056] In addition, in this embodiment, the reference rib line 22 can also be used as a reference for the upper strip segment 42. By observing the overlap position of the reference rib line 22 and the mural simulation test block 10, the overlap position of the strip segment 42 and the mural simulation test block 10 can be determined.

[0057] Specifically, as another embodiment of this application, the strip dividing element 42 is disclosed as a grid line or grid strip. The grid line has a small diameter and is used as the strip dividing element 42 to divide the area, reduce the occluded area, and increase the drawable area on the mural simulation test block 10. The grid strip has a large width, so the occluded parts do not need to be drawn, or are in areas that have already been drawn, thus exposing only the areas that need to be drawn and improving the accuracy of the drawing.

[0058] Specifically, the grid lines and grid strips disclosed in this embodiment can be made of materials such as plastic and metal, which are tough and not easily broken.

[0059] like Figure 1 and Figure 3As shown, as another embodiment of the present application, the drawing auxiliary mold of the mural simulation test block 10 is disclosed, which comprises a positioning base 50, a push rod 60, a lock catch 70 and a limiting plate 80. The positioning base 50 is arranged on the bottom plate 20 and located outside the placement area 21. The positioning base 50 is provided with a through hole 51 and a lock hole 52. The through hole 51 extends towards the center point of the placement area 21. The lock hole 52 is in communication with the through hole 51. The push rod 60 is slidably arranged in the through hole 51. The front end of the push rod 60 extends to the placement area 21. The lock catch 70 is inserted into the lock hole 52 and used to abut against the push rod 60. The limiting plate 80 is arranged at the front end of the push rod 60 and used to contact the mural simulation test block 10.

[0060] In the embodiment, the positioning base 50 is arranged on the bottom plate 20 to constrain the push rod 60. The push rod 60 is movably arranged in the through hole 51 and can be flexibly adjusted in length to be inserted into the placement area 21, thereby abutting against the mural simulation test block 10. Meanwhile, the lock catch 70 is arranged to abut against the push rod 60 to lock the push rod 60, so that the push rod 60 can be fixed in the placement area 21, and the limiting plate 80 at the front end of the push rod 60 is fixed. Specifically, the lock catch 70 and the lock hole 52 can be matched by screwing. By screwing in the lock catch 70, the friction with the push rod 60 can be increased, thereby locking the push rod 60. By screwing out the lock catch 70, the push rod 60 can be unlocked, thereby being flexibly controlled.

[0061] In the embodiment, the limiting plate 80 contacts the mural simulation test block 10, thereby marking the position of the mural simulation test block 10. When a new mural simulation test block 10 is replaced for drawing, the new mural simulation test block 10 can be placed by referring to the position of the limiting plate 80, which is beneficial to accurately aligning the new mural simulation test block 10 with the grid division assembly 40, reducing the preparation time before the next drawing and improving the work efficiency.

[0062] Specifically, in the embodiment, the shape of the limiting plate 80 can be adaptively selected according to the shape of the side wall of the mural simulation test block 10. For example, when the mural simulation test block 10 is a circular plate, the limiting plate 80 can be arranged in the shape of an arc plate. When the mural simulation test block 10 is a triangular plate or a square plate, the limiting plate 80 can be arranged in the shape of a long strip plate. Therefore, the limiting plate 80 can be completely attached to the mural simulation test block 10, thereby accurately marking the position of the mural simulation test block 10. When a new mural simulation test block 10 is replaced, the new mural simulation test block 10 can be attached to the limiting plate 80, thereby achieving the purpose of positioning and being accurately aligned with the grid division assembly 40 on the cover plate 30, which is convenient and fast for starting the next drawing.

[0063] Specifically, the mural simulation test block 10 in use can be placed at any position of the placement area 21. In the embodiment disclosed, the positioning base 50 can be movably arranged, for example, a sliding rail is arranged at the edge of the placement area 21, and the positioning base 50 is arranged on the sliding rail, so that the position of the positioning base 50 can be flexibly adjusted, and then the push rod 60 arranged movably can be flexibly controlled to control the position of the limiting plate 80 in the placement area 21, so as to ensure that the limiting plate 80 can contact the side wall of the mural simulation test block 10.

[0064] For example, as shown in the drawings, in another embodiment of the present application, the positioning assembly composed of the positioning base 50, the push rod 60, the lock 70 and the limiting plate 80 can be arranged in multiple groups, and the multiple groups of positioning assemblies are arranged along the edges of the placement area 21, that is, the limiting plates 80 can be arranged to extend into the placement area 21 from multiple angles and contact the side wall of the mural simulation test block 10, so that multiple limiting plates 80 can be used as reference objects for positioning when a new mural simulation test block 10 is assembled, thereby improving the accuracy of positioning. Figure 1 For example, as shown in the drawings, in another embodiment of the present application, the positioning assembly composed of the positioning base 50, the push rod 60, the lock 70 and the limiting plate 80 can be arranged in multiple groups, and the multiple groups of positioning assemblies are arranged along the edges of the placement area 21, that is, the limiting plates 80 can be arranged to extend into the placement area 21 from multiple angles and contact the side wall of the mural simulation test block 10, so that multiple limiting plates 80 can be used as reference objects for positioning when a new mural simulation test block 10 is assembled, thereby improving the accuracy of positioning.

[0065] Figure 1 For example, as shown in the drawings, in another embodiment of the present application, the positioning assembly composed of the positioning base 50, the push rod 60, the lock 70 and the limiting plate 80 can be arranged in multiple groups, and the multiple groups of positioning assemblies are arranged along the edges of the placement area 21, that is, the limiting plates 80 can be arranged to extend into the placement area 21 from multiple angles and contact the side wall of the mural simulation test block 10, so that multiple limiting plates 80 can be used as reference objects for positioning when a new mural simulation test block 10 is assembled, thereby improving the accuracy of positioning.

[0066] In the embodiment disclosed, the bottom plate 20 and the cover plate 30 are arranged in a top-down manner, and the positioning block 90 is arranged, and the two ends of the positioning block 90 are arranged in the first positioning hole 23 and the second positioning hole 35, so that the positioning block 90 can be quickly positioned and the working efficiency and the accuracy of positioning can be improved.

[0067] Specifically, during actual manufacturing, the bottom plate 20 and the cover plate 30 are manufactured in a matched manner. For example, the bottom plate 20 is manufactured as a square plate, and the cover plate 30 can be manufactured as a square frame with the same peripheral size, so that when the two plates are aligned, the outer edges can be aligned, thereby achieving the effect of auxiliary positioning.

[0068] In the embodiment disclosed, the positioning block 90 can be fixed on the bottom plate 20 by welding or bonding, so that the stability of the positioning block 90 can be improved, and the positioning block 90 can be prevented from being taken out during repeated movement of the cover plate 30. In some application scenarios of the present application, the height of the mural simulation test block 10 to be drawn is indefinite. Specifically, as another embodiment of the present application, the positioning block 90 is a spring or a telescopic multi-stage connecting rod. The height of the positioning block 90 can be controlled by the telescopic property of the spring or the adjustable ability of the multi-stage connecting rod, so that the distance between the cover plate 30 and the bottom plate 20 can be controlled, thereby adapting to mural simulation test blocks 10 with different heights.​

[0069] Specifically, as another embodiment of the present application, the positioning block 90 is magnetically connected with the base plate 20. The positioning block 90 disclosed in this embodiment can be flexibly arranged. For example, the positioning block 90 is a magnet, or a magnet is welded on the positioning block 90, or a magnet is embedded in the base plate 20, so that the positioning block 90 can be stably arranged in the first positioning hole 23 to insert the second positioning hole 35. In particular, the positioning block 90 is detachably magnetically connected with the base plate 20, so that the positioning block 90 can be replaced according to the height of the mural simulation test block 10 at any time to adjust the height of the cover plate 30, thereby avoiding the contact between the grid division assembly 40 and the mural simulation test block 10.

[0070] Specifically, in another embodiment of the present application, a plurality of first positioning holes 23 and a plurality of second positioning holes 35 are provided, and a plurality of positioning blocks 90 are also provided. By providing a plurality of positioning blocks 90, the positioning points are increased, so that the positioning of the cover plate 30 and the base plate 20 is more accurate.

[0071] Specifically, in another embodiment of the present application, the use process of the mural simulation test block 10 drawing auxiliary mold is as follows:

[0072] 1. Place the mural simulation test block 10 on the base plate 20;

[0073] 2. Move the positioning base 50 and the push rod 60, and make the limiting plate 80 adhere to the mural simulation test block 10, and lock the push rod 60 through the lock buckle 70;

[0074] 3. According to the thickness of the mural simulation test block 10, select a positioning block 90 with a suitable height and place it in the first positioning hole 23;

[0075] 4. Cover the cover plate 30, and make the positioning block 90 insert into the second positioning hole 35;

[0076] 5. According to the drawing requirement and the position of the mural simulation test block 10 on the base plate 20, adjust the position of the strip-shaped division piece 42 on the cover plate 30. The strip-shaped division piece 42 is provided with a plurality of strip-shaped division pieces 42, including grid lines and grid strips, and the drawing area connected together is separated by the grid lines, and the strip-shaped area to be drawn is shielded by the grid strips;

[0077] 6. Draw the preset color bar or color block in the drawing area;

[0078] 7. After drawing is completed, take up the cover plate 30, and replace the mural simulation test block 10 for the next drawing.

[0079] In summary, the application discloses a mural simulation test block 10 drawing auxiliary mold, which comprises a bottom plate 20, a cover plate 30 and a grid division assembly 40, the bottom plate 20 is provided with a placement area 21 for placing the mural simulation test block 10, the cover plate 30 is hinged on the bottom plate 20, the cover plate 30 is hollowed out at a position opposite to the placement area 21 to form a drawing area 31, the grid division assembly 40 is arranged on the cover plate 30, the grid division assembly 40 extends to the drawing area 31 and is used for partially covering the mural simulation test block 10 to divide a plurality of drawing areas.
