Description

Technical Field

[0001] The utility model relates to the technical field of furniture manufacturing, in particular to a paint touch-up device for furniture manufacturing with controllable paint surface. Background Art

[0002] During the furniture manufacturing process, anti-corrosion paint needs to be sprayed on the surface of the furniture to ensure the beauty and service life of the furniture. However, some parts of the paint surface may not be sprayed in place or may be worn during the manufacturing process. At this time, it is usually necessary to use a paint touch-up brush to touch up the paint on the furniture.

[0003] The bristles of existing touch-up paint brushes are fixed, and the bristle width of the touch-up paint brushes cannot usually be flexibly adjusted according to the size of the paint surface to be touched up. When the bristle width is large, multiple touch-ups may be caused during the touch-up process. When the bristle width is small, multiple painting processes are required, which is inefficient and causes inconvenience in use. Utility Model Content

[0023] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0024] Example 1

[0025] Reference Figure 1 、 Figure 2 and Figure 3 When the brush is in the brush 1, the brush 1 is moved in a direction of rotation and the brush 2 is moved out of the brush 1. When the brush is in the brush 1, the brush 1 is moved in a direction of rotation and the brush 2 is moved out of the brush 1. When the brush is in the brush 1, the brush 1 is moved in a direction of rotation and the brush 2 is moved out of the brush 1. When the brush is in the brush 1, the brush 1 is moved in a direction of rotation and the brush 2 is moved out of the brush 1. When the brush is in the brush 1, the brush 1 is moved in a direction of rotation and the brush 2 is moved out of the brush 1. When the brush is in the brush 1, the brush 1 is moved in a direction of rotation and the brush 2 is moved out of the brush 1.

[0026] In addition, a screw rod 11 is rotatably provided inside the brush head 1, and a wire sleeve 12 is threadedly connected to the screw rod 11. The wire sleeve 12 is fixedly connected to the top surface of the pressure strip 8. One end of the screw rod 11 extends out of the outside of the brush head 1 and is connected to a knob 20 to facilitate people to rotate the screw rod 11 inside the brush head 1 by hand.

[0027] When in use, people hold the knob 20 and turn the screw rod 11 to rotate. The screw rod 11 can drive the wire sleeve 12 on it to move horizontally while rotating, so that the wire sleeve 12 drives the pressure strip 8 to move toward the inner or outer side of the brush head 1. When the pressure strip 8 moves horizontally toward the inner side of the brush head 1, one end of the pressure strip 8 will contact the middle position of several groups of friction blocks 5 in turn. Since the contact surfaces of the friction block 5 and the pressure strip 8 are mutually fitting inclined surfaces, the friction blocks 5 will press the pressure strip 8 downward, thereby causing the slide rod 4 connected to the friction block 5 to slide downward and push the connecting plate 9 to move downward, so that the bristles 10 extend out of the outside of the brush head 1 in turn. In this process, the spring 6 will be compressed and exert an upward elastic force on the friction block 5. When the pressure strip 8 moves toward the outer side of the brush head 1, several groups of friction blocks 5 will no longer be subjected to the downward pressure of the pressure strip 8 in turn. At this time, the resistance block 5 will move upward under the elastic force of the spring 6, and further drive the connecting plate 9 to move upward through the slide rod 4, so that the bristles 10 can be stored in the brush head 1 in sequence. In summary, the position of the pressure strip 8 inside the brush head 1 can be controlled to further control the number of bristles 10 extending out of the brush head 1, so that when people use the bristles to touch up the paint, they can adjust the number of bristles 10 extending out of the brush head 1 according to the size of the paint surface of the furniture, and then flexibly control the width of the paint surface produced by the bristles 10 during the paint touch-up process, further facilitating people's use. In addition, when the pressure strip 8 is in the required position, the threaded connection between the screw rod 11 and the wire sleeve 12 can keep the wire sleeve 11 fixed, thereby keeping the pressure strip 8 extended into the brush head 1 fixed, and thus will not cause displacement of the pressure strip 8, further allowing the position of the bristles 10 to remain stable, making it convenient for people to perform paint touch-up operations.

[0028] Further, such as Figure 1 As shown, a flexible cover 18 is provided on the brush handle 2. The flexible cover 18 can be made of rubber or sponge. When people hold the brush handle to perform paint touch-up operations, their hands will directly contact the soft flexible cover 18, thereby improving the comfort of their hands.

[0029] Further, such as Figure 2 As shown, a sealing cover 19 is also included for covering the brush head 1. When the device is no longer in use, the sealing cover 19 can cover the open end of the brush head 1 to prevent the bristles from being contaminated by the outside world, thereby ensuring subsequent use.

[0030] Example 2

[0031] Further in the embodiments, please refer to Figure 4 and Figure 5As shown, two groups of opposite through grooves 13 are opened on the upper part of the brush head 1, and a screw 14 is inserted between the two groups of through grooves 13. The two ends of the screw 14 are threadedly connected with nuts 15. The middle of the screw 14 is located inside the brush head 1 and is fixedly connected to the pressure strip 8.

[0032] During use, the screw 14 can be pulled laterally to drive the pressure strip 8 to move toward the inside or outside of the brush head 1. The way in which the pressure strip 8 controls the bristles 10 to extend or be retracted into the inside of the brush head 1 while moving is the same as that in Example 1 and will not be described again. When the pressure strip 8 is in the required position, turning the nuts 15 at both ends of the screw 14 can make the two sets of nuts 15 tightly contact the surface of the brush head 1, so that the position of the screw 14 can be kept fixed, and thus will not cause displacement of the pressure strip 8, further keeping the position of the bristles 10 stable, making it easier for people to perform paint touch-up operations.

[0033] Example 3

[0034] Further in the embodiments, please refer to Figure 6 As shown, an LED lighting lamp 16 is installed on the brush handle 2 , and a USB charging port 17 is provided on the LED lighting lamp 16 .

[0035] The USB charging port 17 can supply power to the LDE lighting lamp 16. When the lighting conditions in the working environment are poor, the USB charging port 17 can provide lighting for the paint touch-up surface, thereby making the paint touch-up operation go more smoothly.
