Description

Technical Field

[0001] The utility model relates to the technical field of wire brushes, in particular to a wear-resistant wire brush. Background Art

[0002] The surface of metal products is often more prone to rust, and peeling and rust removal alone often cannot completely remove the iron oxide scale. It can only remove about 80% because there is still some iron oxide scale powder on the surface of the metal products. The iron oxide scale in some deeper rust pits is more difficult to remove, so other means are needed for further rust removal.

[0003] A search has revealed an authorized Chinese patent, CN 213106183 U, which discloses a wire brush for rust removal. The brush comprises a fixed disc, an internally connected snap-fit block, a rear hinged fan-shaped plate, a front fixedly connected brush filament, a rear fixedly connected first fixed block, a rear fixedly connected second fixed block, a double-threaded rod hingedly connected to the interior of the first fixed block, and a side surface of the double-threaded rod movably connected to the interior of the second fixed block. This wire brush for rust removal allows the angle of the fan-shaped plate to be adjusted by twisting the double-threaded rod, making it easier to adjust the grinding angle of the wire brush and resolving the difficulty traditional wire brushes have in removing rust from corners and crevices.

[0004] The wire brush in the above patent still has certain shortcomings. During actual grinding, the existing wear-resistant wire brush is often unstable in connection with the mounting base, which may easily cause some of the bristles to fall off during the grinding process when the brush is used for rust removal, thereby reducing the overall wear resistance of the wire brush and making it inconvenient for users to use it for a long time.

[0026] Embodiment 1: A wear-resistant wire brush comprises a mounting connecting plate 1, a bottom mounting compartment 2 is provided at the bottom end of the mounting connecting plate 1, a number of bristle fastening assemblies 3 and wire brush bundles 4 are evenly arranged in the bottom mounting compartment 2, the bristle fastening assemblies 3 are used to install and fix the wire brush bundles 4, a top connecting plate 5 is provided at the top end of the mounting connecting plate 1, and a mounting plug rod 6 is provided on the top connecting plate 5.

[0027] The bristle fastening assembly 3 includes a bottom limit plate 301 arranged at the bottom end of the bottom mounting bin 2, and a number of mounting sockets 302 are evenly opened on the bottom limit plate 301. The top ends of the wire brush bundles 4 pass through the middle of the mounting sockets 302. A top limit plate 303 is provided on the side of the top end of the mounting sockets 302. The top ends of the wire brush bundles 4 are in conflict with the top limit plate 303. A number of fastening screws 304 are inserted in the bottom mounting bin 2 for horizontal and even rotation.

[0028] One end of the fastening screw 304 is rotatably connected to the inner wall of the bottom mounting bin 2, and the other end of the fastening screw 304 rotates through the side wall of the bottom mounting bin 2. A number of driving screw sleeves 305 are evenly sleeved on the fastening screw 304, and a bristle resistance plate 306 is provided at the bottom end of the driving screw sleeve 305. A number of connecting plugs 307 are evenly provided on the side of the bristle resistance plate 306. An inner cavity connecting plate 308 is provided above the fastening screw 304, and a limiting slide groove 309 is provided at the bottom end of the inner cavity connecting plate 308. The top end of the driving screw sleeve 305 is slidably inserted in the limiting slide groove 309 through a limiting slider 310.

[0029] Embodiment 2: The difference between this embodiment and embodiment 1 is that the top limiting plate 303 is bent in an L-shape, and the top end of the wire brush bundle 4 is in conflict with the top wall of the top limiting plate 303 .

[0030] The top end of the wire brush bundle 4 can be restrained and installed by the top limiting plate 303 .

[0031] Embodiment 3: The difference between this embodiment and embodiment 1 is that a handle for facilitating rotation is provided at the end of the fastening screw 304 .

[0032] This makes it more convenient for the user to rotate the fastening screw 304 .

[0033] Embodiment 4: The difference between this embodiment and embodiment 1 is that the bristle contact plate 306 is located on one side of the top end of the wire brush bundle 4, and the end of the connecting plug 307 is in the shape of a spike for easy insertion and contact.

[0034] This makes it more stable when the bristle contact plate 306 pushes the connecting plug 307 to contact and fix the top end of the wire brush bundle 4.

[0035] In this embodiment, since the existing wear-resistant wire brush is often unstable in connection with the mounting seat during actual grinding, it is easy for some of the bristles to fall off during the grinding process when the brush is used for rust removal, thereby reducing the overall wear resistance of the wire brush and making it inconvenient for users to use it for a long time.

[0036] In summary, in the specific implementation, when the user needs to evenly install several wire brush bundles 4 on the installation connecting plate 1, the user can first pass the top end of the wire brush bundle 4 through the installation socket 302 in the bristle fastening assembly 3, so that the top end of the wire brush bundle 4 conflicts with the bottom wall of the top limit plate 303, thereby ensuring that all wire brush bundles 4 have sufficient upper parts to be clamped and conflicted, thereby making the installation of the wire brush bundle 4 more stable.

[0037] Then, the user rotates the fastening screw 304, and the driving screw sleeve 305 mounted on the fastening screw 304 can move under the drive of the fastening screw 304, and the driving screw sleeve 305 drives the bristle contact plate 306 to push the connecting plug 307 to clamp the top of the wire brush bundle 4 that contacts the top limit plate 303, so that the wire brush bundle 4 can be more firmly inserted in the bottom mounting bin 2 by the bristle contact plate 306, thereby avoiding the problem of the traditional adhesion installation causing the bristles to fall off easily during use, so that the bristles of the entire device are more firmly installed on the mounting connecting plate 1, thereby improving the overall wear resistance and firmness of the device, and it is also more convenient for users to replace the bristles.
