Description

Technical Field

[0001] This utility model belongs to the field of coating tool technology, and in particular relates to a primer coating tool. Background Technology

[0002] Primer is a solution-like substance applied pre-to the substrate during the application of adhesives or sealants. It cures to form a strong film. The types of primers vary depending on the sealant and the substrate. Its main function is to enhance the adhesion between the adhesive and the substrate. Primer application tools mainly include brushes, rollers, and spray guns. Therefore, it can be seen that existing application tools basically meet people's needs, but the following problems still exist.

[0003] When applying primer using a roller, the operator inserts the roller into the primer container, allowing the primer to adhere to the roller surface. The operator then applies the primer-laden roller to the substrate surface. However, since dust and other debris may adhere to the substrate surface, some dust or debris may remain on the roller surface after the primer is applied. When the roller with dust and debris is reinserted into the primer container, the dust or debris on the roller surface may contaminate the roller inside the primer container. To address this, we propose a primer application tool. Utility Model Content

[0004] This utility model provides a primer application tool. The operator pushes the scraper ring, which slides on the surface of the roller handle. The scraper ring squeezes out the excess primer adhering to the surface of the roller brush, and dust or debris flows out with the squeezed primer, avoiding a large amount of dust and debris remaining on the surface of the roller brush and improving the cleanliness of the primer in the primer bucket.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a primer coating tool, comprising a roller handle and a roller brush, wherein the roller handle is fitted with a roller brush at one end, a scraper ring is fitted with one side end of the roller brush, and a fixing plate is fixed to the surface of the scraper ring, a fixing block is fitted with the middle of the fixing plate, and the fixing block is fixed to the roller handle, wherein the fixing plate and the fixing block are slidably connected.

[0006] Furthermore, a support plate is fixed to the end of the fixing block, and guide sleeves sleeved on the fixing plate are symmetrically fixed to the end of the support plate.

[0007] Furthermore, the tray and the guide sleeve form a rectangular through hole, and the rectangular through hole formed by the tray and the guide sleeve matches the rectangular block set on the fixing plate.

[0008] Furthermore, sliders are symmetrically fixed at both ends of the fixed block, and each slider surface is fitted with a groove opened on the fixed plate. Each groove is provided with a spring that abuts against the slider surface and the inside of the groove.

[0009] Furthermore, a sliding rod passes through the middle of both the spring and the slider, and both ends of the sliding rod are fixed to the inner wall of the groove.

[0010] Furthermore, the fixing plate has grooves on the side away from the scraper ring, and the grooves are all set as arc-shaped grooves.

[0011] The beneficial effects of this utility model are:

[0012] 1. The primer application tool is equipped with a fixed plate, a fixed block, and a scraper ring. After the operator pulls the fixed plate, the fixed plate slides on the surface of the fixed block, and the fixed plate drives the scraper ring to move on the surface of the roller brush. When the scraper ring moves on the surface of the roller brush, it scrapes the primer adhering to the surface of the roller brush, which makes it easy to scrape off the primer after use on the surface of the roller brush, avoids a large amount of dust and debris remaining on the surface of the roller brush, and improves the cleanliness of the primer in the primer container.

[0013] 2. The primer application tool is equipped with a support plate and a guide sleeve. The fixed plate slides within the support plate and the guide sleeve, which pushes the fixed plate and increases the stability of the fixed plate's movement. The guide sleeve restricts the fixed plate and prevents it from sliding left and right between the two sets of guide sleeves when it slides on the support plate surface, thus increasing the stability of the fixed plate's movement.

[0021] To further understand the utility model's content, features, and effects, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0022] Example:

[0023] Please see Figure 1 - Figure 5 A primer application tool includes a roller handle 1 and a roller brush 2. The roller brush 2 is sleeved on the end of the roller handle 1, and a scraper ring 6 is sleeved on one side of the roller brush 2. A fixing plate 3 is heat-fused to the surface of the scraper ring 6. A fixing block 10 is sleeved in the middle of the fixing plate 3 and heat-fused to the roller handle 1. The fixing plate 3 and the fixing block 10 are slidably connected. Slider blocks 12 are symmetrically heat-fused to both ends of the fixing block 10. The surface of each slider 12 is sleeved with a groove 4 formed on the fixing plate 3. A spring 8 is provided inside each groove 4, which abuts against the surface of the slider 12 and the inside of the groove 4, respectively. When the operator needs to scrape off the primer containing impurities and dust from the surface of the roller brush 2, the operator first pulls the fixing plate 3, and the fixing plate 3 slides on the surface of the fixing block 10. When the fixed plate 3 slides on the surface of the fixed block 10, the fixed plate 3 drives the slide groove 4 to move, so that the slide groove 4 slides on the surface of the slider 12. When the slide groove 4 slides on the surface of the slider 12, the gap between the slide groove 4 and the slider 12 continuously decreases. The slide groove 4 and the slider 12 compress the spring 8 against each other, causing the spring 8 to undergo elastic deformation and contract. The spring 8 avoids the slide groove 4, allowing the slide groove 4 to slide on the surface of the slider 12. When the fixed plate 3 slides on the surface of the fixed block 10, the fixed plate 3 drives the scraper ring 6 to move, so that the scraper ring 6 slides on the surface of the roller brush 2. The scraper ring 6 scrapes the primer adhering to the surface of the roller brush 2, avoiding a large amount of dust and debris remaining on the surface of the roller brush 2, and improving the cleanliness of the primer in the primer bucket.

[0024] In other embodiments, a support plate 5 is heat-fused to the end of the fixing block 10, and a guide sleeve 7 fitted onto the fixing plate 3 is symmetrically heat-fused to the end of the support plate 5. When the fixing plate 3 moves, the fixing plate 3 slides on the surface of the support plate 5, so that the support plate 5 supports the fixing plate 3, increasing the stability of the movement of the fixing plate 3 and preventing the fixing plate 3 from shaking up and down when it moves on the surface of the fixing block 10. In addition, when the fixing plate 3 moves, it moves between the two sets of guide sleeves 7, so that the guide sleeves 7 restrict the sides of the fixing plate 3, preventing the fixing plate 3 from shaking left and right when it moves, and improving the stability of the movement of the fixing plate 3.

[0025] In other embodiments, the support plate 5 and the guide sleeve 7 form a rectangular through hole, and the rectangular through hole formed by the support plate 5 and the guide sleeve 7 matches the rectangular block provided on the fixing plate 3. The rectangular through hole formed by the support plate 5 and the guide sleeve 7 matches the rectangular block provided on the fixing plate 3, so that the surface of the fixing plate 3 fits in close contact with the inside of the guide sleeve 7 and the support plate 5, thereby increasing the stability of the fixing plate 3 sliding within the guide sleeve 7 and the support plate 5.

[0026] In other embodiments, a sliding rod 9 passes through the middle of both the spring 8 and the slider 12, and the two ends of the sliding rod 9 are heat-fused to the inner wall of the groove 4. When the groove 4 slides on the surface of the slider 12, the groove 4 drives the cylindrical sliding rod 9 to slide in the circular through hole in the middle of the slider 12, so that the sliding rod 9 pulls the movement trajectory of the slider 12, increasing the stability of the movement of the slider 12. Furthermore, the slider 12 passes through the spring 8, so that the slider 12 restricts the spring 8 and prevents the spring 8 from leaking out through the opening of the groove 4.

[0027] In other embodiments, the fixed plate 3 is provided with a groove 11 on the side away from the scraper ring 6, and the groove 11 is set as an arc-shaped groove. When the operator pulls the fixed plate 3, the operator inserts his / her hand into the groove 11, so that the groove 11 can accommodate the operator's hand and improve the comfort of the operator pulling the fixed plate 3.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
