[0018] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0019] Reference Figure 1-Figure 6As shown, the painting stand for construction engineering of this embodiment includes a first support frame 1, a second support frame 2 and a pedal 3. The first support frame 1 is provided with a rotatable first connecting rod 4, and the first connecting rod 4 is arranged at the lower end of the first support frame 1. The first connecting rod 4 is rotatably connected to the upper end of the second support frame 2. The lower end of the second support frame 2 is provided with a rotatable second connecting rod 5. The upper end of the first support frame 1 is provided with a rotatable third connecting rod 6, and the second connecting rod 5 is connected to the first connecting rod 4. The third connecting rod 6 is connected to the first connecting rod 4. The pedal 3 is detachably arranged on the first support frame 1 and the second support frame 2.

[0020] Through the above technical solution, the first support frame 1 and the second support frame 2 are connected into a whole through the first connecting rod 4, and are divided into a support frame part and a stepping pedal 3 part when being carried; when the painting frame is unfolded and installed, the first support frame 1 is first placed on the platform position below the stairs, the first support frame 1 is placed against the wall, and then the second support frame 2 is carried to the platform position above the stairs. During this process, the first connecting rod 4 rotates relative to the first support frame 1 and the second support frame 2, and then the second connecting rod 5 is rotated to connect the second connecting rod 5 with the first connecting rod 4. At this time, the first support frame 1 and the second support frame 2 are initially positioned, and then the third connecting rod 6 is rotated to connect it with the first connecting rod 4, and then the stepping pedal 3 is installed to complete the unfolding and installation. When disassembling, the operation can be reversed. This design can be operated by one person, is easy to disassemble and assemble, and is flexible to use. It is suitable for environments where the height difference between the upper and lower platforms is different, and has a wide range of applications. After the unfolding and installation is completed, the first support frame 1, the second support frame 2, the first connecting rod 4, the second connecting rod 5, and the third connecting rod 6 form multiple supporting triangles, and the structure is stable.

[0021] As an improved specific embodiment, a plurality of positioning buttons 41 are provided on the inner side of the first connecting rod 4, a second connecting rod 5 is provided on the side close to the end thereof, a second connecting rod 5 is provided on the side close to the second support frame 2 of the second entry slot 51, a second clamping slot 52 is provided on the side close to the end thereof of the third connecting rod 6, a third entry slot 61 is provided on the side close to the end thereof, a third connecting rod 6 is provided on the side close to the first support frame 1 of the second entry slot 51, and the positioning button 41 can enter the second entry slot 51, the second clamping slot 52, the third entry slot 61, and the third clamping slot 62.

[0022] By the above technical solution, when the second connecting rod 5 is rotated to be connected to the first connecting rod 4, the second support frame 2 is rotated first and then the second connecting rod 5 is rotated. The suitable position of the second support frame 2 is that the angle between the second support frame 2 and the platform facing the side of the first support frame 1 (hereinafter referred to as angle A) is 85°-95°, and then the second connecting rod 5 is rotated so that the second entry groove 51 wraps the positioning button 41 at the corresponding position, and then the second support frame 2 is rotated toward the first support frame 1 so that the positioning button 41 enters the second card slot 52. At this time, the angle A is less than 90°;

[0023] When the third connecting rod 6 is rotated to connect with the first connecting rod 4, the first support frame 1 is rotated first and then the third connecting rod 6. The appropriate position of the first support frame 1 is that the angle between the first support frame 1 and the platform facing the second support frame 2 (hereinafter referred to as angle B) is 85°-95°. Then the third connecting rod 6 is rotated so that the third entry groove 61 wraps the positioning button 41 at the corresponding position, and then the first support frame 1 is rotated toward the second support frame 2 so that the positioning button 41 enters the third slot 62. At this time, the angle B is less than 90°.

[0024] The above structure is easy to install and disassemble, and after installation, the support frame can maintain a stable position, which is convenient for placing the pedal 3.

[0025] As an improved specific implementation, a closing piece 42 is provided on the positioning button 41 , and a gap is provided between the closing piece 42 and the first connecting rod 4 , and the width of the gap is greater than the widths of the second connecting rod 5 and the third connecting rod 6 .

[0026] Through the above technical solution, the closing piece 42 prevents the second connecting rod 5 and the third connecting rod 6 from falling off the positioning button 41, further improving the stability of the paint rack after it is unfolded.

[0027] As an improved specific implementation, the first support frame 1 is provided with cross-arranged first reinforcing rods 11 , and the second support frame 2 is provided with cross-arranged second reinforcing rods 21 .

[0028] Through the above technical solution, the first reinforcing rods 11 are cross-arranged in the first support frame 1, thereby improving the structural strength of the first support frame 1, and the second reinforcing rods 21 are cross-arranged in the second support frame 2, thereby improving the structural strength of the second support frame 2.

[0029] As an improved specific implementation, a plurality of mounting grooves 31 are provided at the lower end of the pedal 3, a first support rod 12 is provided on the first support frame 1, and a second support rod 22 is provided on the second support frame 2, and the mounting grooves 31 can wrap the first support rod 12 and the second support rod 22.

[0030] Through the above technical solution, when the pedal 3 is installed on the first support frame 1 and the second support frame 2, the installation groove 31 at the corresponding position wraps the first support rod 12 and the second support rod 22 to complete the deployment installation. The pedal 3 fixes the position of the first support frame 1 and the second support frame 2 from the upper side, so that the second clamping groove 52 and the third clamping groove 62 can stably wrap the corresponding positioning button 41 to avoid separation from the positioning button 41, further improving the stability of the paint rack after deployment.

[0031] As an improved specific implementation, the first support rods 12 have several groups distributed from top to bottom, and the second support rods 22 have several groups distributed from top to bottom.

[0032] Through the above technical solution, the first support rod 12 and the second support rod 22 have several groups, so that the placement height of the pedal 3 is adjustable, with a wide range of applications and flexibility.

[0033] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
