[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example 1:

[0026] See Figures 1 to 3 As shown, a splash-proof device for roller coating includes an arc-shaped baffle 1 for being disposed on the lower side of roller A. A connecting plate 2 is disposed on the inner arc surface of the arc-shaped baffle 1, and a clamping block 3 is disposed on the outer side of the connecting plate 2. A laterally open slot 31 is longitudinally opened on the clamping block 3, and the slot 31 is used to elastically clamp the support rod of the roller brush.

[0027] This paint splash preventer has a simple structure and low production cost. It can block paint dripping downwards from roller A or splashing outwards during the painting process, preventing paint from dripping onto the operator's hands or splashing onto the operator's body, thus reducing the operator's cleaning work. It mainly utilizes the clamping block 3 to elastically clamp onto the roller brush, enabling quick installation and removal of the paint splash prevention device. It is simple to operate and is especially suitable for home self-painting.

[0028] In other embodiments, the cross-sectional shape of the arc-shaped baffle 1 can also be a straight plate or other shapes.

[0029] The connecting plate 2 is inclined relative to the arc-shaped baffle 1. The clamping block 3 is connected to one side of the inner inclined surface of the connecting plate 2. The slot 31 is inclined and is elastically clamped on the inclined section C of the support rod. When the slot 31 is clamped on the inclined section C, the arc-shaped baffle 1 can still maintain a horizontal state relative to the roller brush.

[0030] In other embodiments, the connecting plate 2 can also be set upright, simply by tilting the slot 31 onto the clamping block 3.

[0031] The lower half of the arc-shaped baffle 1 is connected to one side of the connecting plate 2, and the clamping block 3 is connected to the other side of the connecting plate 2. The lower half of the arc-shaped baffle 1 has a notch 51 for avoiding the support rod corresponding to the slot 31. When the device is in use, the outer arc surface of the arc-shaped baffle 1 faces the direction of the painter, which can prevent paint from dripping onto the painter's hands. When the paint drips onto the inner arc surface of the arc-shaped baffle 1, it will flow out of the arc-shaped baffle 1 to the inside.

[0032] The connecting plate 2 is located in the middle of the arc-shaped baffle 1, and the slot 31 is elastically clamped at the bottom of the inclined section C; The position of the connecting plate 2 is determined by the position of the slot 31 in the inclined section C. By default, the arc-shaped baffle 1 is centered on the lower side of the roller brush. Therefore, when the slot 31 is elastically clamped at the bottom of the inclined section C, setting the connecting plate 2 in the middle position of the arc-shaped baffle 1 can achieve the default situation, but it will increase the distance between the roller brush and the arc-shaped baffle 1. When the distance between the roller brush and the arc-shaped baffle 1 is shortened, the position of the slot 31 clamped in the inclined section C will gradually rise. Therefore, setting the connecting plate 2 towards one side of the arc-shaped baffle 1 can achieve the default situation.

[0033] See Figure 5 As shown, the slot 31 includes a circular groove 311 that matches the shape of the support rod. One side of the circular groove 311 is provided with an outward clamping inlet and outlet 312. The diameter of the clamping inlet and outlet 312 is smaller than the diameter of the support rod. The clamping inlet and outlet 312 of this structure can restrict the support rod within the circular groove 311 after it is inserted into the circular groove 311, ensuring the installation connection effect. Moreover, when disassembling the paint splash prevention device, the operator only needs to apply force to open the clamping inlet and outlet 312 with the support rod to remove the paint splash prevention device from the roller brush. The structure is simple and the installation is convenient.

[0034] The clamping block 3 has a cross-section that is narrower at the front and wider at the back, forming an equilateral trapezoidal shape. This structure increases the area of ​​the clamping block 3 connected to the connecting plate 2 and also reduces the outer thickness of the clamping inlet and outlet 312, making it easier for the clamping inlet and outlet 312 to achieve elastic deformation.

[0035] The tilt angle of the slot 31 is 130° or 145°. In actual production, it is preferred to set the tilt angle to 130° or 145°. When using a 9-inch large roller, the tilt angle should be 145°, and the tilt angle of a 4-inch small roller should be 130°.

[0036] The arc-shaped baffle 1 and the connecting plate 2 are integrally made of transparent plastic material. The clamping block 3 is also made of plastic material. The arc-shaped baffle 1 and the connecting plate 2 are made of plastic with a thickness of about 1-2mm, which can minimize the weight of the paint splash prevention device. Moreover, they are transparent, so even if the operator observes from above, the paint accumulation can still be seen. The clamping block 3 can be integrally injection molded with the connecting plate 2, or it can be fixed to the connecting plate 2 with glue. Example 2:

[0037] The difference between Embodiment 2 and Embodiment 1 is that: a sliding groove 201 is longitudinally provided on the outer surface of the connecting plate 2. The sliding groove 201 can be formed by a recess inward on the connecting plate 2 with a certain thickness, or, see... Figure 4 As shown, two protruding ribs 202 are connected to the outer side of the connecting plate 2, and a sliding groove 201 is formed between the two protruding ribs 202. At this time, there are multiple clamping blocks 3, each with a different size slot 31. When the paint splash prevention device needs to be installed on roller brushes of different specifications (in which case the diameter of the support rod is different), the clamping blocks 3 can be detachably slidably connected in the sliding groove 201, thereby changing the size of the slot 31, improving the practicality of the paint splash prevention device and making it more flexible to use.

[0038] In Embodiment 1, the cross-section of the clamping block 3 is in the shape of an equilateral trapezoid, therefore the sliding groove 201 is a matching dovetail groove.

[0039] In other embodiments, the clamping block 3 can also be made of ordinary magnets or neodymium magnets. The clamping block 3 and the support rod form a stable magnetic connection. This method allows the clamping block 3 to eliminate the structure of the slot 31. On the other hand, the clamping block 3 with a magnetic field can meet the use of roller brushes of different specifications. Even if the roller brush uses support rods of different diameters, the adaptability is better. Example 3:

[0040] Example 3 differs from Example 1 in that: See Figure 6 As shown, the arc-shaped baffle 1 can be divided into two sections, including a fixed baffle 11 and an adjustable baffle 12. The connecting plate 2 is connected to one side of the fixed baffle 11, and the adjustable baffle 12 is slidably connected to the outside of the fixed baffle 11 through a slide rail structure. By extending and retracting the adjustable baffle 12 relative to the fixed baffle 11, the length of the arc-shaped baffle 1 can be adjusted to match rollers A of different lengths. Example 4:

[0041] In Example 4, see Figures 7 to 10As shown, the arc-shaped baffle 1 is approximately a semi-circular arc structure, and the connecting plate 2 is set on one side of the arc-shaped baffle 1; in addition, a corner block 4 is provided on the lower side of the clamping block 3, and a limiting groove 41 is provided on the corner block 4 to receive the slot 31. The limiting groove 41 is set downward and inward, and the limiting groove 41 is used to abut against the top of the inclined rod section C of the roller brush. The slot 31 is elastically clamped on the straight rod section B of the support rod. Once the paint splash prevention device is installed in place, the engagement of the limiting groove 41 and the inclined rod section C can prevent the paint splash prevention device from sliding down. Moreover, the inclined rod section C and the straight rod section B engage with the slot 31 or the limiting groove 41 in different directions, which can prevent the paint splash prevention device from swaying left and right along the central axis of the straight rod section B, ensuring that the arc-shaped baffle 1 can be aligned with the lower side of the roller A.

[0042] An arc-shaped side baffle 5 extends from one side of the arc-shaped baffle 1. The connecting plate 2 is fixed between the arc-shaped baffle 1 and the arc-shaped side baffle 5. The arc-shaped side baffle 5 has a notch 51 for avoiding the inclined rod segment C. The arc-shaped side baffle 5 can exceed the length of the roller A, which provides a redundant effect for blocking the paint and ensures the blocking effect of the paint splash prevention device.

[0043] The other side of the arc-shaped baffle 1 is open and forms a paint drain port 101 for draining paint. When paint drips onto the arc-shaped baffle 1, the paint can be drained away in time through the paint drain port 101, thus preventing the arc-shaped baffle 1 from collecting more and more paint and gradually increasing the weight of the paint splash prevention device.

[0044] See Figure 5 As shown, the included angle Θ between the two sides of the arc-shaped baffle 1 is between 140° and 160°; in this embodiment, the included angle Θ is preferably 150°, so that the width of the arc-shaped baffle 1 is greater than the diameter of the roller, thereby increasing the blocking area and improving the blocking effect.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
