Description

Technical Field

[0001] The utility model belongs to the technical field of building construction equipment, and specifically relates to a wall painting structure for painting with water-based silver powder paint. Background Art

[0002] Water-based paint is a kind of paint that uses water as a solvent and can save a lot of resources. It greatly reduces the pollution of chemical paint to the atmosphere and can also avoid the danger of construction fires. Today, as people pursue environmental protection more, more environmentally friendly water-based paint is gradually replacing oil paint to facilitate people's lives. In the process of painting water-based paint, the more traditional method is to dip the brush roller into the water-based paint, absorb the paint and then paint it. This method is inefficient and the paint is easy to spill when dipped, causing waste. Therefore, there are liquid pumps and pipes on the market to connect the paint roller and the paint box to continuously supply the paint to the paint roller. However, the general feeding method is to spray the paint on the brush roller from the outside and from top to bottom. The disadvantage of this method is that when the brush roller is turned over, the paint becomes sprayed from bottom to top, and the lack of spraying power makes it easy to spill outside.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] Example 1

[0031] This embodiment provides a wall painting structure for water-based silver paint painting, as shown in the attached Figure 1 and attached Figure 2 As shown, it includes a brush roller unit and a telescopic rod unit arranged at the lower end of the brush roller unit.

[0032] It can be understood that the brush roller unit is a prior art, and can directly refer to the document with authorization announcement number CN218508948U, which discloses structures including a U-shaped fixing frame, a seepage pipe, a brush roller, etc.; the brush roller unit is also connected to the paint storage and transportation device, and the paint storage and transportation device can also directly refer to or transfer the prior art, including structures such as a cart, a storage box, a stirrer, a metering pump, a hose, etc.

[0033] In this embodiment, the telescopic rod unit is mainly structurally modified in order to overcome the problems existing in the prior art: first, the height adjustment structure is complicated, time-consuming and labor-intensive; second, it cannot be adjusted in real time during the painting process.

[0034] In this embodiment, the telescopic rod unit includes a mounting rod 1, an adjusting rod 2, and an operating rod 3 connected in sequence. One end of the mounting rod 1 is fixedly connected to the middle of the lower end of the brush roller unit, and the other end is fixedly connected to the upper end of the adjusting rod 2.

[0035] In this embodiment, the operating rod 3 includes a rod body 31, a telescopic groove 32 arranged at the upper end of the rod body 31 and used to insert the adjusting rod 2, a lifting spring 33 arranged in the telescopic groove 32 and connected to the lower end of the adjusting rod 2, and at least two adjusting ropes 34 arranged at the side end of the lifting spring 33 and one end of which is connected to the lower end of the adjusting rod 2.

[0036] It is worth noting that a lifting spring 33 is fixedly installed on the bottom surface of the telescopic slot 32, and the other end of the lifting spring 33 is connected to the bottom of the lower end of the adjusting rod 2, and in the absence of external force, the lifting spring 33 supports the lifting adjusting rod 2 and the lower end of the adjusting rod 2 will not be separated from the telescopic slot 32. At this time, it is the maximum length of the operating rod 3, and in this state, the brush roller unit has a certain buffering effect when brushing because of the existence of the lifting spring 33, which is conducive to improving the brushing effect and the quality of the paint surface. The adjusting rope 34 is an inelastic rope body, one end of which is fixedly connected to the bottom surface of the adjusting rod 2, and in order to balance the force requirements, the adjusting rope 34 is two ends, symmetrically installed on both sides of the lifting spring 33. The end of the adjusting rope 34 away from the adjusting rod 2 is a free end, and the free end can directly pass through the telescopic slot 32 to the outside of the rod body 31. By acting on the free end to pull the adjusting rod 2 downward to press the lifting spring 33, the overall length of the telescopic rod unit is shortened, thereby achieving the purpose of adjusting the length of the operating rod 3. In addition, the adjustment is a real-time stepless adjustment, which has strong flexibility and the effect of saving time and effort.

[0037] It is worth noting that after the free end of the adjustment rope 34 determines the degree of compression of the lifting spring 33, it is necessary to apply a continuous and stable force to it or directly fix it. In order to achieve the above purpose, those skilled in the art are capable of finding an existing structure to achieve it, so it will not be repeated in this embodiment.

[0038] In this embodiment, the operating rod 3 further includes an operating handle 39 disposed at the lower end of the rod body 31. The operating handle 39 is used for direct gripping to facilitate painting work.

[0039] Example 2

[0040] Compared with the first embodiment, the present embodiment mainly optimizes the installation method of the jacking spring 33 and the adjustment rope 34, thereby further improving the stability of the structure and reducing the difficulty of operation. Figure 3 and attached Figure 4 As shown, the specific structure is as follows:

[0041] The operating rod 3 also includes a partition plate 35 arranged in the telescopic groove 32 and connected to the end of the lifting spring 33 away from the adjusting rod 2, a ring platform 36 arranged on the peripheral side of the partition plate 35 and protruding from the wall of the telescopic groove 32, a wire hole 37 arranged on the ring platform 36 and used for the adjusting rope 34 to pass through, and an adjusting roller 38 rotatably arranged in the space between the partition plate 35 and the bottom surface of the telescopic groove 32 and used for installing the end of the adjusting rope 34 away from the adjusting rod 2.

[0042] The adjusting roller 38 includes a fixed shaft 381 rotatably connected to the wall of the telescopic groove 32, a roller body 382 arranged on the fixed shaft 381 and used to wind the adjusting rope 34, an extension rod 383 arranged at the end of the fixed shaft 381 and protruding from the outer wall of the rod body 31, a rotating handle 384 arranged on the extension rod 383, a fixed column 385 rotatably arranged on the outer wall of the rod body 31, a limiting clamping plate 386 arranged at the end of the fixed column 385 and connected to the extension rod 383, and a limiting ring plate 387 arranged on the outer peripheral side of the roller body 382.

[0043] The adjusting rod 2 and the partition plate 35 are respectively provided with two limiting grooves 310 for mounting the two ends of the lifting spring 33 .

[0044] In this embodiment, the partition 35 divides the telescopic slot 32 into two spaces, the upper space is used to install the jacking spring 33 and the adjustment rod 2, and the lower space is used to install the adjustment roller 38 that fixes the free end of the adjustment rope 34. Among them, the structural setting of the ring platform 36 and the wire hole 37 has the purpose of providing a passage for the adjustment rope 34 that will not interfere with the jacking spring 33, and the second purpose is that the protruding ring platform 36 can strengthen the end of the jacking spring 33 to avoid the undesirable situation of skewing when it is stressed. It should be noted that the setting height and thickness of the ring platform 36 cannot be higher than the deepest insertion height of the adjustment rod 2, otherwise it will affect the shortest construction length of the telescopic rod unit as a whole.

[0045] In this embodiment, the working principle of the adjusting roller 38 is as follows: the free ends of the two adjusting ropes 34 are passed through the wire holes 37 and fixed on the two sides of the roller body 382 respectively. When the handle 384 is rotated in one direction, the adjusting ropes 34 are gradually rolled up on the roller body 382, ​​and the length of the adjusting ropes 34 becomes shorter, which promotes the pulling of the adjusting rod 2 to press the lifting spring 33, thereby shortening the overall length of the telescopic rod unit. When rolled up to a suitable position, the fixing column 385 is rotated to make the limit clamping plate 386 clamp the extension rod 383. At this time, the extension rod 383 cannot rotate, and the length of the adjusting rope 34 is determined. When the overall length of the telescopic rod unit needs to be extended, the locking of the extension rod 383 by the limit clamping plate 386 is first released, and then the handle 384 is rotated in the opposite direction of the original direction. When the length is determined, the limit clamping plate 386 is clamped to the extension rod 383 again.

[0046] The principle of locking the extension rod 383 by the limit clamp 386 is to limit the rotation of the extension rod 383. The limit clamp 386 may be in a claw hook shape or any other shape known in the art, so it will not be described in detail in this embodiment.

[0047] Compared with Example 1, the present embodiment integrates the structure for installing the adjustment rope 34 on the operating rod 3, and the entire adjustment structure is similar to the line-releasing and line-reeling structure of the fishing rod in the prior art, and can be operated with one hand. The operation process is simple and labor-saving, and it can be adjusted in real time during the construction process, which has the advantage of strong practicality. At the same time, the entire adjustment process is stepless adjustment, which has the advantage of strong flexibility.

[0048] Example 3

[0049] The difference between this embodiment and the embodiment 1 is that a limit clamp is provided at the connection between the adjusting rod 2 and the operating rod 3 to prevent the adjusting rod 2 and the operating rod 3 from falling off or tilting, thereby causing uneven force on the lifting spring 33. Figure 5 As shown, the specific structure is as follows:

[0050] The limit clamping member includes at least two elastic plates 21 obliquely arranged on the side wall of the lower end of the adjusting rod 2, at least two openings 22 arranged on the upper end of the rod body 31 and connected to the telescopic groove 32, and an annular groove 23 arranged on the inner wall of the notch of the telescopic groove 32 and connected to the two openings 22.

[0051] Among them, the elastic plate 21 itself has a certain deformation ability. Under pressure, the angle between the elastic plate 21 and the side wall of the adjusting rod 2 becomes smaller, so that it can smoothly pass through the annular groove 23 and enter the opening 22. When moving to the opening 22, the force acting on the elastic plate 21 disappears, so the elastic plate 21 restores the angle between it and the side wall of the adjusting rod 2, so that the elastic plate 21 allows the farthest end of the elastic plate 21 from the side wall of the adjusting rod 2 to pass through the opening 22 and protrude from the outer wall of the rod body 31, thereby ensuring that the lower end of the adjusting rod 2 will not slip out of the telescopic groove 32.

[0052] It is worth noting that the opening 22 is a strip hole, in which the elastic plate 21 can move up and down, and the maximum moving distance of the elastic plate 21 is greater than or equal to the maximum compression distance of the jacking spring 33. The purpose of this setting is to prevent the elastic plate 21 from interfering with the movement of the adjustment rod 2 in the telescopic slot 32.

[0053] Example 4

[0054] The difference between this embodiment and the embodiment 1 is that the adjustment rod 2 and the installation rod 1 are detachably installed, which is convenient for the maintenance and replacement of components. As shown in Appendix 3, the specific structure is as follows:

[0055] A mounting piece is provided at the connection between the adjusting rod 2 and the mounting rod 1, and the mounting piece includes an insertion rod 24 provided at the lower end of the mounting rod 1, a socket 25 provided at the upper end of the adjusting rod 2 and used to insert the insertion rod 24, two fixing holes 26 provided on the two side walls of the adjusting rod 2 and connected to the socket 25, a fixing stud 27 that passes through the insertion rod 24 and has two ends passing through the two fixing holes 26 respectively, and a fixing nut 28 screwed on the upper end of the fixing stud 27.

[0056] It is worth noting that the two fixing holes 26 at the same height form a group, and multiple groups can be set on the adjustment rod 2. This arrangement can facilitate the adjustment of the insertion depth of the insertion rod 24, and further adjust the overall length of the telescopic rod unit.

[0057] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
