Multi-angle painting type high-efficiency water-absorbing roller brush

Abstract

This application discloses a multi-angle, high-efficiency, water-absorbing roller brush, relating to the field of roller brushes. It includes a handle with an adjustment mechanism at the top. This invention, through the adjustment mechanism, facilitates the rotation of the roller at a certain angle, creating an angle between the roller and the handle. Manually pressing down the push rod pushes the limiting plate inward via the double lugs. The first spring deforms under pressure, and the limiting plate removes two locking blocks from their corresponding semi-circular slots. Manually rotating the rotating block around the hollow column, after a certain angle, removes the push rod. Under the action of the first spring, a reverse force is applied to the limiting plate, causing the two locking blocks to engage in their corresponding semi-circular slots, fixing the rotating block at that angle. This allows for adjustment of the roller's rotation angle on the hollow column, improving the efficiency of roller coating in confined spaces.

Description

Technical Field

[0001] This utility model relates to the field of roller brush technology, and in particular to a high-efficiency water-absorbing roller brush that can be used for multi-angle brushing. Background Technology

[0002] In the field of painting and cleaning, roller brushes are a commonly used tool, but their functional limitations are becoming increasingly apparent with the diversification of application scenarios. In particular, when painting complex surfaces (such as inside and outside corners and curved walls) and cleaning damp environments (such as bathroom tiles and kitchen countertops), traditional roller brushes, due to their fixed angles, are unable to meet the needs of efficient operation.

[0003] Adjust the roller brush to a certain angle on the handle and fix it in the rotated position. Then, use the roller brush to brush the desired wall surface. Quickly replace the roller brush by squeezing it.

[0004] Existing high-efficiency water-absorbing roller brushes for painting are not convenient for adjusting the vertical angle of the roller when painting small areas, thus reducing the efficiency of wall painting. They are also not convenient for quick replacement. Therefore, a multi-angle painting high-efficiency water-absorbing roller brush is proposed. Utility Model Content

[0014] (III) Beneficial Effects This invention provides a multi-angle, high-efficiency, water-absorbing roller brush. It has the following beneficial effects: 1. The adjustment mechanism allows the roller to be rotated at a certain angle, creating an angle between the roller and the handle. This facilitates adjusting the angle for painting in confined spaces. Manually pressing the push rod downwards pushes the limiting plate inwards via the double lugs. The first spring deforms under pressure, and the limiting plate moves two locking blocks out of their corresponding semi-circular slots. The rotating block is then manually rotated around the hollow column. After rotating a certain angle, the pushing force on the push rod is released. Under the action of the first spring, a reverse force is applied to the limiting plate, causing the two locking blocks to engage in their corresponding semi-circular slots, fixing the rotating block at that angle. This mechanism adjusts the rotation angle of the roller on the hollow column, improving the efficiency of coating in confined spaces.

[0015] 2. The telescopic mechanism facilitates quick replacement of the rollers and allows for the installation of rollers of different lengths. By pulling the top plate outward, the roller shaft is removed from the top plate, and the shaft at the other end of the roller is removed from the L-shaped plate. After removing the roller, a new roller is installed. To replace it, one end of the roller shaft is inserted into the L-shaped plate, and the top plate is pulled outward. Under the action of the second spring, the top plate pushes one side of the roller to fix it in place. This facilitates roller replacement and reduces operating costs. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Example 1 Reference Figure 1 , Figure 2 and Figure 3 This is the first embodiment of the present invention. This embodiment provides a multi-angle brushing type high-efficiency water-absorbing roller brush, including a handle 1, an adjustment mechanism 2 provided on the top of the handle 1, and a telescopic mechanism 3 provided inside the handle 1.

[0025] The adjustment mechanism 2 includes circular baffles 201 symmetrically installed on the top of the handle 1. A rotating circular block 202 is movably installed on one side of the two circular baffles 201. An L-shaped plate 203 is installed on the outer surface of the rotating circular block 202. A roller 204 is provided inside the L-shaped plate 203. A hollow column 207 is installed at the center of one side of the two circular baffles 201. A limiting plate 205 is sleeved on the outer surface of the hollow column 207. A first spring 208 is provided on one side of the limiting plate 205. A double ear plate 210 adapted to the limiting plate 205 is provided inside the hollow column 207. A locking block 206 is symmetrically provided on one side of the limiting plate 205.

[0026] Specifically, the hollow column 207 has a double-mouthed sliding groove inside that is adapted to the double ear plate 210. The double ear plate 210 is slidably connected inside the double-mouthed sliding groove. The double ear plate 210 is fixedly connected to the limiting plate 205. The limiting plate 205 is slidably connected to the outside of the hollow column 207. The first spring 208 is located on the outside of the hollow column 207, and its other end is fixedly connected to the flipping round block 202. Under the action of the first spring 208, a pushing force is applied to the limiting plate 205, causing the limiting plate 205 to drive the two locking blocks 206 to lock into the flipping round block 202. The flipping round block 202 is rotated around the hollow column 207. After adjusting a certain angle, under the action of the two locking blocks 206, the flipping round block 202 is fixed at the angle after rotation.

[0027] Specifically, a push rod 209 is installed on one side of the double ear plate 210, and a sliding hole adapted to the push rod 209 is opened on one side of the round baffle 201. The push rod 209 is slidably connected inside the sliding hole. The diameter of the hollow column 207 is larger than the sliding hole of the round baffle 201. Under the action of the push rod 209, the push rod 209 applies a certain pushing force to the limiting plate 205 through the double ear plate 210, so that the limiting plate 205 drives the two locking blocks 206 to move out of the flipping round block 202, thereby releasing the restriction on the flipping round block 202.

[0028] Specifically, a semi-circular locking hole adapted to the locking block 206 is provided on one side of the flipping block 202. The locking block 206 is movably locked inside the semi-circular locking hole. A circular groove adapted to the limiting plate 205 is provided inside the circular baffle 201. The limiting plate 205 is slidably connected inside the circular groove. When the locking block 206 is locked into the corresponding semi-circular locking hole of the flipping block 202, the flipping block 202 can be restricted from rotating on the opposite side of the two circular baffles 201. After the flipping block 202 is rotated around the hollow column 207 at a certain angle on the opposite side of the two circular baffles 201, the locking block 206 is inserted into the corresponding semi-circular locking groove, and the flipping block 202 is fixed in that position after rotation.

[0029] Further, manually push the push rod 209 inward. The push rod 209 drives the double ear plate 210 to move within the hollow column 207. The double ear plate 210 drives the limiting plate 205 to move outside the hollow column 207. At this time, the first spring 208 is deformed under pressure. The limiting plate 205 drives the two locking blocks 206 to move, removing the two locking blocks 206 from the corresponding semi-circular slots of the flipping block 202. Manually flip the flipping block 202 around the hollow column 207. The flipping block 202 drives the L-shaped plate 203 to flip, and the L... The forming plate 203 flips the roller 204 at a certain angle on the top of the handle 1. At this time, the pushing force applied to the push rod 209 is removed. Under the action of the first spring 208, the first spring 208 pushes the limiting plate 205 in the opposite direction. The limiting plate 205 pushes the two locking blocks 206 in the opposite direction, so that the two locking blocks 206 are locked into the semi-circular locking slots corresponding to the flipping round block 202. At this time, the limiting plate 205 pushes the push rod 209 outward through the double ear plate 210, so that the flipping round block 202 can be fixed at the angle position after rotation.

[0030] Example 2 Reference Figure 4 and Figure 5 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The telescopic mechanism 3 includes a top plate 301 movably installed on the top of the L-shaped plate 203. T-shaped blocks 302 are symmetrically installed on the bottom of the top plate 301. A second spring 303 is symmetrically arranged on one side of the T-shaped block 302. A stop block 305 adapted to the top plate 301 is symmetrically arranged on the outer surface of the roller 204 shaft.

[0031] Specifically, a rotating hole adapted to the rotating shaft of the roller 204 is provided on one side of the top plate 301. The roller 204 is movably installed inside the rotating hole via a bearing. A stop block 305 is located on one side of the top plate 301. A T-shaped groove adapted to the T-shaped block 302 is symmetrically provided on the top of the L-shaped plate 203. The T-shaped block 302 is slidably connected inside the T-shaped groove. When the top plate 301 moves, the action of the two T-shaped blocks 302 ensures that the top plate 301 can move stably, inserting the rotating shaft of the roller 204 into the rotating hole of the top plate 301. Under the action of the stop block 305, the roller 204 can rotate stably around the rotating shaft.

[0032] Specifically, the telescopic mechanism 3 also includes symmetrically arranged T-shaped bars 304. The T-shaped bars 304 are located on opposite sides of the two second springs 303. A T-shaped sliding hole adapted to the T-shaped bar 304 is opened on one side of the T-shaped block 302. The T-shaped bar 304 is slidably connected inside the T-shaped sliding hole. Under the action of the T-shaped bar 304, when the second spring 303 is deformed by pressure, it prevents the second spring 303 from popping out of the T-shaped groove of the L-shaped plate 203, thus ensuring the stability of the second spring 303.

[0033] Furthermore, manually pull the top plate 301 outward. The top plate 301 drives the two T-shaped blocks 302 to move within the L-shaped plate 203. At this time, the T-shaped blocks 302 compress and deform the corresponding two second springs 303. During the movement of the T-shaped blocks 302, the T-shaped blocks 302 slide outside the T-shaped strip 304. The second springs 303 on the T-shaped strip 304 pop out, and after the top plate 301 is removed from the rotating shaft of the roller 204, the other end of the roller 204 is pulled out from the L-shaped plate 203. Once removed, roller 204 can be replaced with a new roller 204. First, insert one end of roller 204 into L-shaped plate 203, then align the other end of roller 204 with the rotating hole of top plate 301. Remove the tension applied to top plate 301. Under the action of the corresponding second spring 303, push T-shaped block 302 in the opposite direction. T-shaped block 302 pushes top plate 301 toward roller 204, so that top plate 301 abuts against stop block 305, thus completing the replacement of roller 204.

[0034] Working principle: During the brushing process, when it is necessary to adjust the angle between the roller 204 and the handle 1, manually push the push rod 209 inward. The push rod 209 drives the double ear plate 210 to move in the hollow column 207. The double ear plate 210 drives the limiting plate 205 to move outside the hollow column 207. At this time, the first spring 208 is deformed under pressure. The limiting plate 205 drives the two locking blocks 206 to move, moving the two locking blocks 206 out of the corresponding semi-circular slots of the flipping block 202. Manually move the flipping block 202 around the hollow column 207. When column 207 flips, the flipping block 202 drives the L-shaped plate 203 to flip as well. The L-shaped plate 203 flips the roller 204 at a certain angle on top of handle 1. At this time, the pushing force applied to push rod 209 is removed. Under the action of the first spring 208, the first spring 208 pushes the limiting plate 205 in the opposite direction. The limiting plate 205 pushes the two locking blocks 206 in the opposite direction, so that the two locking blocks 206 are engaged in the corresponding semi-circular slots of the flipping block 202. At this time, the limiting plate 205 pushes the push rod 209 outward through the double ear plate 210. The rotating circular block 202 is fixed at the rotated angular position. During use, when replacing the roller 204, the top plate 301 is manually pulled outward. The top plate 301 drives the two T-shaped blocks 302 to move within the L-shaped plate 203. At this time, the T-shaped blocks 302 compress and deform the corresponding two second springs 303. During the movement of the T-shaped blocks 302, they slide outside the T-shaped strip 304. The second springs 303 in the T-shaped strip 304 pop out, and the top plate 301 is removed from the roller 204's rotating shaft. Pull the other end of roller 204 out of L-shaped plate 203 to remove roller 204 and replace it with a new roller 204. First, insert one end of roller 204 into L-shaped plate 203, then align the other end of roller 204 with the rotating hole of top plate 301. Remove the tension applied to top plate 301. Under the action of the corresponding second spring 303, push T-shaped block 302 in the opposite direction. T-shaped block 302 pushes top plate 301 toward roller 204, so that top plate 301 abuts against stop block 305, thus completing the replacement of roller 204.
