Description

Technical Field

[0001] The utility model relates to a paint roller, in particular to an angle adjustment operating rod and a paint roller with the operating rod. Background Art

[0002] The paint roller is a commonly used wall painting tool, which consists of a roller, a curved rod and a plastic handle. One end of the curved rod is connected to the rotating shaft of the roller, and the other end is connected to the plastic handle. The plastic handle is relatively short and has a socket opened axially inside. When painting low places, the plastic handle can be directly held to operate. When painting high places, the plastic handle is generally put on an operating rod, and the roller is lifted up by the operating rod for operation.

[0003] When using an operating rod for painting, in order to ensure that the roller fits the wall, it can only be rolled up and down or at a small angle (otherwise the operating rod needs to be designed to be very long, and people have to stand far away to operate, affecting normal use). When faced with narrow spaces such as narrow gaps (such as the gap between the air conditioner and the wall), the roller cannot be inserted into the gap and other tools must be replaced.

[0004] The patent with application number 201820721147.3 discloses an adjustable building paint roller, which is achieved by providing a gear-shaped through hole on the paint roller and a rectangular hole on the top of a hand-held rod. After two teeth of the gear-shaped through hole are aligned with the rectangular hole, a plug is inserted into the rectangular hole to adjust the angle of the paint roller. However, each time it is adjusted, it must be manually fixed before it can be used again, and only certain angles can be adjusted, and continuous adjustment is not possible.

[0005] In order to solve the above problems, people have been seeking an ideal technical solution. Summary of the invention

[0006] The utility model aims to address the deficiencies of the prior art and thus provide an angle-adjusting operating rod and a paint roller with the operating rod, which can be used for painting in a narrow space, does not require manual fixing, can be continuously adjusted, and is easy to operate.

[0007] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: an angle adjustment operating rod, including a hand-held rod, a rotating rod and an arbitrary stop damping rotating shaft, the top of the hand-held rod is provided with a hinge groove, the bottom end of the rotating rod is installed in the hinge groove through the arbitrary stop damping rotating shaft, and the top of the rotating rod gradually becomes thinner and is used to insert a plastic handle of a paint roller.

[0008] Based on the above, two parallel fan-shaped plates are arranged on both sides of the hinge slot, the center of the fan-shaped plates is located at the axis center of the arbitrary stop damping shaft, and the hinge slot is respectively installed with limiting columns near the edges on both sides, and the two limiting columns limit the rotation angle of the rotating rod.

[0009] Based on the above, one end of the limit column is fixed to one of the fan-shaped plates, and the other end of the limit column is provided with a threaded section. The other fan-shaped plate is provided with a through hole corresponding to the threaded section. After the threaded section passes through the through hole, an adjusting nut is connected to fine-tune the opening degree of the two fan-shaped plates, thereby adjusting the tightness of the arbitrary stop damping shaft.

[0010] Based on the above, a friction pad is provided on the inner side of each of the fan-shaped plates. As the adjusting nut gradually adjusts the opening degree of the two fan-shaped plates, the friction pad can completely clamp or completely loosen the plastic handle of the paint roller.

[0011] Based on the above, a lever is connected to the outer wall of the adjusting nut.

[0012] The utility model also provides a paint roller, comprising a roller, a plastic handle and the angle adjustment operating rod as described above, wherein the plastic handle is plugged into the rotating rod.

[0013] The utility model has substantial characteristics and progress compared with the prior art. Specifically, the utility model has the following advantages:

[0014] (1) By setting the arbitrary stop damping shaft, the rotating rod has a certain damping when rotating and can hover at any position. When in use, just put the roller against the wall and press hard to drive the rotating rod to rotate automatically until the roller fits the wall. Then, when rolling, the force is small and the roller can maintain a hovering state, so it can be suitable for painting in a small space. There is no need to manually fix the rotation angle, which makes the operation more convenient.

[0015] (2) By installing limit columns on the edges of the two fan-shaped plates, the rotation angle of the rotating rod can be conveniently limited; by setting the threaded section and the adjusting nut, the tightness of the arbitrary stop damping shaft can be conveniently adjusted to improve the comfort of use; the setting of the friction pad can completely clamp the plastic handle and lock the rotating rod at a certain angle by adjusting the opening degree of the two fan-shaped plates; the setting of the lever makes it convenient for fingers to turn the adjusting nut.

[0022] The technical solution of the utility model is further described in detail below through specific implementation methods.

[0023] like Figure 1-3 As shown, a paint roller comprises a roller 1, a plastic handle 2 and an angle adjustment operating rod, wherein a plug hole is provided in the plastic handle 2 along the axial direction; the angle adjustment operating rod comprises a hand-held rod 3, a rotating rod 4 and an arbitrary stop damping rotating shaft 5, a hinge groove 6 is provided at the top of the hand-held rod 3, and the bottom end of the rotating rod 4 is installed in the hinge groove 6 through the arbitrary stop damping rotating shaft 5, the top of the rotating rod 4 gradually becomes thinner, and the plastic handle 2 is inserted into the rotating rod 4.

[0024] Working principle:

[0025] When the rotating rod 4 rotates with the arbitrary stop damping shaft 5, it has a certain damping and can hover at any position. When in use, just put the roller 1 against the wall and press it hard to drive the rotating rod 4 to rotate automatically until the roller 1 fits the wall. Then when rolling, the force is small and the hovering state can be maintained, so it is suitable for painting in a small space. There is no need to manually fix the rotation angle, and the operation is more convenient.

[0026] Two parallel fan-shaped plates 7 are arranged on both sides of the hinge slot 6, the center of the fan-shaped plates 7 is located at the axis of the arbitrary stop damping shaft 5, and the hinge slot 6 is respectively installed with limit posts 8 near the edges on both sides. The two limit posts 8 limit the rotation angle of the rotating rod 4. In this embodiment, the rotation range of the rotating rod 4 is 10°-170°. Figure 4As shown, when the rotating rod 4 is rotated to the maximum angle, the hand-held rod 3 can be rotated to make the fan-shaped plate 7 perpendicular to the wall, and the top of the hand-held rod 3 is tilted forward, so that the roller 1 can be vertically attached to the wall and painted in a small space; Figure 5 As shown, when the rotating rod 4 rotates at a moderate angle, the hand-held rod 3 is rotated to make the intersection line of the plane where the fan-shaped plate 7 is located and the wall surface a horizontal line, and the roller 1 contacts the wall surface obliquely and is pushed and pulled obliquely for rolling.

[0027] One end of the limit column 8 is fixed to one of the fan-shaped plates 7, and the other end of the limit column 8 is provided with a threaded section 81. The other fan-shaped plate 7 is provided with a through hole corresponding to the threaded section 81. After the threaded section 81 passes through the through hole, it is connected with an adjusting nut 9. A lever 10 is connected to the outer wall of the adjusting nut 9, which is convenient for twisting the adjusting nut 9 by hand. In this way, the opening degree of the two fan-shaped plates 7 can be fine-tuned, and then the tightness of the arbitrary stop damping shaft 5 can be adjusted to make the operation more comfortable.

[0028] A friction pad 11 is provided on the inner side of each of the sector plates 7. As the adjusting nut 9 gradually adjusts the opening degree of the two sector plates 7, the friction pad 11 can completely clamp or completely loosen the plastic handle 2 of the paint roller; when fully clamped, the rotating rod 4 can be locked at a certain angle, which can be used in situations where one posture is required for long-term use of the roller.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for protection of the utility model.
