Description

Technical Field

[0001] This utility model relates to the field of brush shaft technology, specifically to an easy-to-disassemble brush shaft with replaceable bristle sections. Background Technology

[0002] A brush shaft roller typically consists of a metal shaft, a bristle attachment body (plastic tube, nylon tube, etc.), and bristles. The manufacturing process includes: shaft turning, sleeve casting, eyelet cutting, bristle trimming, and bristle smoothing. Traditional brushes usually employ a one-piece structure, requiring replacement of the entire brush after bristle wear, which is costly and environmentally unfriendly; alternatively, the bristles are glued in place, leaving adhesive residue during replacement and affecting reinstallation. Industrial cleaning, agricultural machinery, and other fields require quick changes in bristle type (e.g., hardness, density) for different scenarios, but existing brush shafts are cumbersome to disassemble and assemble, making efficient modular replacement difficult. The connection strength between the bristle sections and the shaft in split-type brushes is insufficient, easily loosening and falling off during high-speed rotation, especially since the fit between the T-slot and the mounting post lacks anti-detachment design. Therefore, we propose an easily detachable brush shaft with replaceable bristle sections. Utility Model Content

[0003] To address the problems in the existing technology, this utility model proposes an easily detachable brush shaft with replaceable bristle sections.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A replaceable brush shaft with easy-to-disassemble bristle section includes a shaft head, a central shaft, an attachment block, and a brush mounted on the attachment block. The shaft head is detachably mounted on both sides of the central shaft. The attachment block is arc-shaped, and multiple T-shaped strips are fixed in a circular array around the central shaft. The upper end face of the attachment block has an array of first mounting holes, and the lower end face of the attachment block is formed with a mounting part. The mounting part has a T-shaped groove, and each T-shaped strip is inserted into the corresponding T-shaped groove. The brush includes a mounting post and a sleeve. One end of the mounting post has a threaded part, and the sleeve has an internal thread. The sleeve and the threaded part of the mounting post are connected by threads, and the outside of the sleeve is covered with bristles. The other end of the mounting post has a connector, and the connector is detachably connected to the first mounting hole.

[0005] As a further improvement to this solution, a second mounting hole is provided at one end of the mounting post, and a limiting hole is provided through the corresponding sleeve. After the threaded part of the sleeve and the mounting post are installed, they are laterally limited by the fixing screw.

[0006] As a further improvement to this solution, the replaceable bristle section of the easy-to-disassemble brush shaft also includes a blocking part, which is fixed to the upper and lower sides of one end of the central shaft by bolts.

[0007] As a further improvement to this solution, an arc-shaped baffle is fixed on the outer edge of the blocking part, and the lower bottom surface of the arc-shaped baffle presses against the central shaft.

[0008] As a further improvement to this solution, the length of the sleeve is matched with the length of the threaded portion of the mounting post.

[0009] As a further improvement to this design, the central shaft adopts a double-layer extruded structure of carbon structural steel.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. The brush bristle section of this novel brush shaft is equipped with multiple attachment blocks with T-shaped long grooves installed around the central shaft, making the whole assembly and disassembly convenient.

[0011] 2. The modular assembly and disassembly of the brush bristles is achieved through a threaded connection between the sleeve and the mounting post. Replacement only requires unscrewing the sleeve; the entire brush shaft can be replaced quickly. The plug-in design of the first mounting hole and connector further simplifies the assembly and disassembly process, making it suitable for frequent replacement scenarios.

[0012] 3. After the sleeve and the mounting post are connected by threads, a fixing screw is used to limit the movement laterally to prevent the threads from loosening during high-speed operation, providing double anti-loosening protection. Attached Figure Description

Detailed Implementation

[0016] 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.

[0017] Example 1 like Figure 1-5 As shown, this embodiment provides an easily detachable brush shaft with replaceable bristle sections, including a shaft head 1, a central shaft 2, an attachment block 5, and a brush 6 mounted on the attachment block 5.

[0018] Function of shaft head 1: Installed at both ends of the central shaft 2, providing support and power transmission interface (such as connecting a motor). The detachable design facilitates maintenance or replacement of the central shaft 2 and attachment block 5.

[0019] The central shaft 2 serves as the main support structure, with T-shaped strips arranged in a ring around it to secure the attachment blocks 5. The central shaft 2 employs a double-layer extruded carbon structural steel structure, which enhances rigidity, reduces weight, and is suitable for high-speed rotation or high-load applications.

[0020] The shaft head 1 is detachably mounted on both sides of the central shaft 2. The attachment block 5 is arc-shaped. Multiple T-shaped strips are fixed in a ring array around the central shaft 2. The upper end face of the attachment block 5 is provided with an array of first mounting holes 52. The lower end face of the attachment block 5 is formed with a mounting part 50. The mounting part 50 is provided with a T-shaped long groove 51. Each T-shaped strip is inserted into the corresponding T-shaped long groove 51. The brush 6 includes a mounting post 61 and a sleeve 63. One end of the mounting post 61 is provided with a threaded part. The sleeve 63 is provided with an internal thread. The sleeve 63 is connected to the threaded part of the mounting post 61 by a thread. The outside of the sleeve 63 is covered with brush bristles. The other end of the mounting post 61 is provided with a connector 62. The connector 62 and the first mounting hole 52 are detachably connected.

[0021] One end of the mounting post 61 is provided with a second mounting hole 64, and a limiting hole is provided through the corresponding sleeve 63. After the threaded parts of the sleeve 63 and the mounting post 61 are installed, they are laterally limited by the fixing screw 65.

[0022] The length of sleeve 63 matches the length of the threaded portion of mounting post 61.

[0023] The replaceable bristle section of the easily detachable brush shaft also includes a blocking part 3, which is fixed to the upper and lower sides of one end of the central shaft 2 by bolts 4. An arc-shaped baffle is fixed to the outer edge of the blocking part 3, and the lower surface of the arc-shaped baffle presses against the central shaft 2. The blocking part 3 is fixed to the end of the central shaft 2 by bolts 4, restricting the axial displacement of the attachment block 5. The arc-shaped baffle presses against the surface of the central shaft 2, enhancing the stability of the blocking part and preventing the brush assembly from loosening during high-speed rotation.

[0024] The specific installation and working principle are as follows: The first mounting hole 52 on the upper end face of the attachment block 5 is used to connect the connector 62 of the brush 6, thereby fixing the brush axially. The T-shaped groove 51 on the lower end face slides with the T-shaped strip of the central shaft 2, ensuring that the attachment block 5 cannot move radially after being installed axially. The arc-shaped strip design fits the circumference of the central shaft 2, achieving a uniform distribution of multiple sets of brushes 6.

[0025] The brush 6 includes a mounting post 61 and a sleeve 63. One end of the mounting post 61 has a threaded section, which is threaded to the sleeve 63 for easy replacement of the bristle section. The other end has a connector 62, which is inserted into the first mounting hole 52 for axial fixation. The sleeve 63 is covered with bristles and is screwed onto the mounting post 61 for fixation via internal threads.

[0026] The sleeve 63 is equipped with a limiting hole and is laterally locked by the fixing screw 65 to prevent the threads from loosening. Its modular design allows for independent replacement of a single damaged brush, reducing maintenance costs. The length of the sleeve 63 matches the threaded section to ensure connection stability. The brush 6, through its threaded connection and plug-in design, allows for easy removal and replacement without tools.

[0027] In summary, this novel brush shaft bristle section utilizes multiple attachment blocks with T-shaped grooves mounted around the central shaft, facilitating easy assembly and disassembly. Modular assembly and disassembly of the bristle section are achieved through threaded connections between the sleeve and mounting post. Replacement only requires unscrewing the sleeve, eliminating the need to disassemble the entire brush shaft, enabling quick replacement of individual brushes. The plug-in design of the first mounting hole and connector further simplifies the assembly and disassembly process, making it suitable for frequent replacement scenarios. After the sleeve and mounting post are threaded together, a lateral locking screw provides double anti-loosening protection, preventing loosening during high-speed operation.

[0028] The above description is merely an illustrative example of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described, or use similar methods to replace them, as long as they do not deviate from the structure of this utility model or exceed the scope defined in the claims, all of which should fall within the protection scope of this utility model.
