Description

Technical Field

[0001] This utility model relates to the field of roller brush technology, specifically to an adjustable length roller brush handle. Background Technology

[0002] Roller brushes are commonly used painting tools in architectural decoration. They come in long-bristle, medium-bristle, and short-bristle varieties, and are made from materials such as wool, synthetic fibers, and foam plastics to meet the needs of different paints and application effects. When using them, pre-treat the roller brush first. Pay attention to the technique and pressure when rolling to ensure even application and avoid splattering. Be gentle when finishing the edges. After application, clean and maintain the brush promptly. Remove any residual paint with water or thinner. For stubborn stains, use a special cleaning agent. Afterward, let it air dry and store it in a dry and ventilated place to extend its service life. Roller brushes are mainly used for large-area painting in architectural decoration projects, such as interior and exterior wall paints, latex paints, anti-rust paints, and wallpaper paste. They have a wide rolling range and are the most labor-saving and time-saving brush tool. Especially when attached with an extension rod, it can easily paint high places on walls or ceilings.

[0003] According to the publication number CN206473010U on the China Patent Network, a roller brush handle includes a handle head, a handle neck, and a handle body. The handle head is located on the handle neck and has two opposing fan-shaped surfaces. The bottom of the two fan-shaped surfaces is connected by a rounded transition, forming a "U"-shaped cross-section with the "U"-shaped opening flaring outwards. One end of the handle neck is connected to the bottom arc surface of the handle head, and the other end transitions to the handle body. Several protrusions are provided on both sides of the handle neck extending towards the two fan-shaped surfaces of the handle head. This utility model of a roller brush handle solves the problems of insufficient hand comfort and limited arm extension and force application in the prior art of roller brush handles. However, the adjustment effect of this roller brush handle is poor, and it is relatively fixed in use. It is difficult to adjust the length according to different usage needs, and it can only adapt to fixed usage scenarios, which is difficult to meet the user's needs.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1 to 4 As shown, the present invention provides an adjustable length roller brush handle, including a handle body 1, an adjustment component 2 and a positioning component 3;

[0027] The adjustment assembly 2 includes a movable handle 201, which is located inside the handle body 1. The top of the handle body 1 extends through to the top of the movable handle 201. A circular groove 202 is provided at the bottom of the handle body 1. An arc-shaped strip 203 is fixedly connected to the inner wall of the circular groove 202. There are two arc-shaped strips 203. Teeth 204 are fixedly connected to the inner side of the arc-shaped strips 203. A toothed plate 205 is engaged on the inner side of the teeth 204. The toothed plate 205 is located inside the handle body 1. A connecting ring 206 is fixedly connected to the bottom of the toothed plate 205. The connecting ring 206 is located inside the handle body 1. A rotating sleeve 207 is fixedly connected to the bottom of the connecting ring 206. The rotating sleeve 207 is movably connected to the movable handle 201.

[0028] refer to Figure 4 The positioning component 3 includes a through-hole 301, which is located at the bottom of the rotating sleeve 207. A short rod 302 is fixedly connected to the bottom of the handle body 1. The short rod 302 is located inside the through-hole 301 and is slidably connected to the through-hole 301. A round block 303 is fixedly connected to the bottom of the short rod 302. A magnetic sleeve 304 is fixedly connected to the bottom of the rotating sleeve 207. The round block 303 is located inside the magnetic sleeve 304 and is attracted to the magnetic sleeve 304.

[0029] As a technical optimization of this utility model, by setting the positioning component 3, the rotating sleeve 207 and the toothed plate 205 can be positioned to prevent the rotating sleeve 207 and the toothed plate 205 from rotating, thereby improving the stability of the rotating sleeve 207 and the toothed plate 205.

[0030] refer to Figure 2 A ring 4 is fixedly connected to the surface of the handle body 1, and the ring 4 is located inside the rotating sleeve 207.

[0031] As a technical optimization of this utility model, by setting the ring 4, the rotating sleeve 207 can be limited to prevent the rotating sleeve 207 from detaching from the handle body 1, thereby improving the stability of the rotating sleeve 207.

[0032] refer to Figure 1 An anti-slip sleeve 5 is fixedly connected to the surface of the handle body 1, and the surface of the anti-slip sleeve 5 is provided with anti-slip texture.

[0033] As a technical optimization of this utility model, by setting the anti-slip sleeve 5, the friction between the handle body 1 and the user can be increased, making the user's grip on the handle body 1 more comfortable and improving the ease of rotation of the handle body 1.

[0034] refer to Figure 1 An elastic sleeve 6 is fixedly connected to the surface of the rotating sleeve 207. The elastic sleeve 6 is made of elastic rubber.

[0035] As a technical optimization of this utility model, by setting the elastic sleeve 6, the friction between the rotating sleeve 207 and the user can be increased, thereby improving the ease of rotation of the rotating sleeve 207.

[0036] refer to Figure 2 A reinforcing ring 7 is fixedly connected to the surface of the toothed plate 205, and the reinforcing ring 7 is located inside the handle body 1.

[0037] As a technical optimization of this utility model, by setting a reinforcing ring 7, the toothed plate 205 can be strengthened, preventing the toothed plate 205 from deforming when moving, and improving the overall strength of the toothed plate 205.

[0038] The working principle and usage process of this utility model are as follows: When it is necessary to flexibly adjust the length of the handle body 1, simply rotate the rotating sleeve 207 gently. The rotating sleeve 207, with the help of the connecting ring 206, will drive the toothed plate 205 to rotate slowly, causing the toothed plate 205 to disengage from the arc-shaped strip 203. Then, the movable handle 201 can be smoothly pulled upwards to freely adjust its length, easily achieving the desired length. After the length is adjusted to the ideal state, rotate the rotating sleeve 207 again, and the connecting ring 206... Driven by 06, the toothed plate 205 rotates and meshes tightly with the teeth 204. At the same time, the short rod 302 drives the round block 303 to rotate until the round block 303 is precisely screwed into the magnetic sleeve 304. The magnetic sleeve 304 and the round block 303 are instantly attracted. In this way, the strong attraction force of the magnetic sleeve 304 can firmly fix the rotating sleeve 207 and the toothed plate 205, effectively preventing the toothed plate 205 from detaching from the arc strip 203, and truly achieving a reliable fixing effect to meet the user's needs.

[0039] In summary, this adjustable-length roller brush handle utilizes an adjustment component to adjust the length of the moving handle. It can be adjusted during use to meet different usage needs, adapting to various scenarios and satisfying user requirements, thus solving the problem of difficult adjustment.
