AI Technical Summary
In existing coating leveling tests, the lack of constraints in the leveling ruler causes the paint trace to bend, and the movement of the substrate affects the test results.
A leveling test bench was designed to move the leveling ruler through the side plate and the transverse hole guide, and the base was fixed in combination with the clamp to ensure that the paint traces were straight and the coating was prevented from diffusion through the L-shaped blocking plate.
The straightness of the paint traces and the fixation of the substrate are achieved, avoiding the impact of the paint traces bending and the movement of the substrate on the test results, and improving the accuracy of the test.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of paint testing, in particular to a leveling test bench. Background Art
[0002] The leveling property of paint is often called flattening property or finishing property. Through the leveling property test, the leveling effect or decorative property of the paint can be verified and evaluated. When conducting the test, first place the selected substrate on the test bench, then place the leveling ruler at one end of the substrate, and then pour the test paint in front of the leveling ruler. Then move the leveling ruler, and form multiple paint traces on the substrate through the grooves on the leveling ruler. Then observe the time when the traces disappear and conduct grading. Generally, those within no more than 10 minutes are good; 10 - 15 minutes are qualified; those that are not uniform after 15 minutes are unqualified. However, during the operation, since there is no restraint on the leveling ruler, it is very easy to make the paint traces bend, thus affecting the test results. In addition, when moving the leveling ruler, it is very easy to make the substrate move synchronously, thus affecting the brushing of the test traces. Content of the Utility Model
[0003] The utility model provides a leveling test bench to solve the above-mentioned deficiencies of the prior art, which can ensure the straightness of the traces and has strong practicability.
[0004] In order to achieve the purpose of the utility model, the following technology is proposed:
[0005] A leveling test bench includes a bottom plate. Lower pads are respectively arranged on the lower walls at both ends of the bottom plate. A side plate is installed on one side of the lower pad. A pair of transverse holes are opened on the side plate. A connecting screw is movably arranged in the transverse hole. An outer movable end plate is arranged at the outer end of the connecting screw. The outer movable end plate is located outside the side plate. A leveling ruler is arranged at the inner end of the connecting screw. The side plate and the transverse holes provided play a guiding role in the movement of the leveling ruler to ensure that the painted traces have good straightness.
[0006] Further, a vertical plate is installed on the side wall of the lower pad through a screw. A vertical hole is opened on the vertical plate. A movable rod passes through the vertical hole. An inner movable plate is arranged at the inner end of the movable rod. A clamping plate is arranged at the lower end of the inner movable plate. The clamping plate provided can clamp the substrate to prevent the substrate from moving.
[0007] Further, an outer movable plate is installed at the outer end of the movable rod. A rotating rod is rotatably arranged on the outer wall of the outer movable plate. A rotating shaft is arranged at the upper end of the outer wall of the vertical plate. A turntable is rotatably arranged on the rotating shaft. An acting rotating plate is arranged on the turntable. The lower end of the acting rotating plate is of an arc structure. The lower end of the acting rotating plate is tangent to the rotating rod. The lower end of the acting rotating plate acts on the rotating rod through the setting, so as to facilitate the clamping and restraint of the substrate by the clamping plate.
[0008] Further, a bayonet is formed at the arc-shaped structure at the lower end of the rotating plate, and the setting of the bayonet ensures the stability after clamping.
[0009] Further, a handle rod is provided on the turntable to facilitate the clamping operation.
[0010] Further, a moving handle rod is provided on the movable outer end plate, and the leveling ruler can be conveniently moved through the moving handle rod.
[0011] Further, an L-shaped baffle is provided on the front side of the leveling ruler, and the L-shaped baffle can prevent the paint from spreading outward and affecting the painting effect.
[0012] The advantages of the above technical solutions are as follows:
[0013] The utility model can ensure that the traces after painting are straight, and can clamp the base material to prevent the movement of the base material from having an adverse effect on the painting traces. BRIEF DESCRIPTION OF THE DRAWINGS
[0014] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0016] Figure 2 Shows an enlarged view of part A.
[0017] Figure 3 Shows the three-dimensional structure of one of the embodiments Figure 2 . DETAILED DESCRIPTION OF THE EMBODIMENTS
[0018] As Figures 1 to 3 shown, a leveling test bench includes a bottom plate 1. Lower pads 10 are respectively provided on the lower walls at both ends of the bottom plate 1. A side plate 3 is installed on one side of the lower pad 10. A pair of transverse holes 30 are formed in the side plate 3. A connecting screw 31 is movably provided in the transverse hole 30. An outer end plate 32 is provided at the outer side end of the connecting screw 31. The outer end plate 32 is located outside the side plate 3. A leveling ruler 34 is provided at the inner side end of the connecting screw 31. A moving handle rod 33 is provided on the outer end plate 32. An L-shaped baffle 35 is provided on the front side of the leveling ruler 34.
[0019] The side wall of the lower cushion block 10 is provided with a vertical plate 2 through screws. A vertical hole 20 is formed in the vertical plate 2. A movable rod 21 is inserted into the vertical hole 20. An inner movable plate 22 is provided at the inner end of the movable rod 21. A clamping plate 23 is provided at the lower end of the inner movable plate 22. An outer movable plate 24 is installed at the outer end of the movable rod 21. A rotating rod 25 is rotatably provided on the outer wall of the outer movable plate 24. A rotating shaft 27 is provided at the upper end of the outer wall of the vertical plate 2. A turntable is rotatably provided on the rotating shaft 27. An acting rotating plate 26 is provided on the turntable. The lower end of the acting rotating plate 26 is of an arc structure. The lower end of the acting rotating plate 26 is tangent to the rotating rod 25. A bayonet is formed at the arc structure at the lower end of the acting rotating plate 26. A handle rod 28 is provided on the turntable.
[0020] During the operation of this embodiment, the operator first places the base material on the bottom plate 1.
[0021] Then, the operator rotates the acting rotating plate 26 through the handle rod 28, so that the lower end of the acting rotating plate 26 acts on the rotating rod 25, thereby causing the rotating rod 25 to move downward. The downward movement of the rotating rod 25 will clamp the two ends of the base material through the clamping plate 23 until the bayonet is clamped on the outer circumference of the rotating rod 25.
[0022] Then, the operator pours the paint in front of the leveling ruler 34 and inside the L-shaped baffle 35.
[0023] Next, the operator moves the leveling ruler 34 through the moving handle rod 33. When the leveling ruler 34 moves, it will form a painting trace through the groove provided on it. After the painting is completed, the leveling effect is observed and rated.
