Description

Technical Field

[0001] This utility model relates to the field of brush grip technology, specifically to an anti-torsion quick-release brush grip. Background Technology

[0002] In motor equipment, the brush holder is a key component that fixes the brush and ensures stable contact between it and the commutator or slip ring. Its ease of installation and structural stability directly affect the assembly efficiency and operating performance of the motor.

[0003] Traditional brush holders lack positioning functionality between the brush assembly and the mounting base. After the brush assembly is placed on the base, it is prone to springing, twisting, turning, and shifting due to the springs. This requires repeated alignment adjustments during assembly, which is time-consuming. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an anti-torsion quick-install brush holder, which solves the problem that traditional brush holders lack positioning functionality between the brush assembly and the mounting base. After the brush assembly is placed on the base, it is prone to springing, twisting, turning, and shifting due to the spring, requiring repeated alignment adjustments during assembly, which is time-consuming.

[0005] This utility model provides the following technical solution: an anti-torsion quick-release brush grip, including a mounting post and a brush assembly. The brush assembly includes a brush block, a brush braid is provided on one end surface of the brush block, a metal pressure plate is fixedly installed on one end of the brush braid, a spring is fixedly connected between the brush block and the metal pressure plate, and two positioning plates are fixedly connected to the lower surface of the metal pressure plate. The surfaces of the two positioning plates are provided with locking components.

[0006] The upper end of the mounting post is fixedly connected to a mounting block. The surfaces of the mounting block and the mounting post are provided with mounting grooves that match the brush block. The upper surface of the mounting block is provided with two positioning grooves that match the positioning piece.

[0007] Preferred technical solution 1: The locking component includes protrusions disposed on the surfaces of the two positioning plates, and both protrusions are made of elastic material.

[0008] Preferred technical solution 2: An installation sleeve is fixedly connected to the upper part of the installation block, and the inner wall of the installation sleeve is provided with a threaded groove.

[0009] Preferred technical solution 3: The brush braid is woven from multiple strands of fine copper wire, and the brush block is made of graphite material.

[0010] Preferred technical solution four: Both the mounting column and the mounting block are made of copper and their surfaces are fitted with round tubes made of plastic or bakelite powder.

[0011] Compared with the prior art, the present invention provides a quick-release brush grip with anti-twist, which has the following advantages: by setting a precise matching structure between the positioning plate and the positioning groove, and a locking component composed of elastic protrusions, the brush assembly can be quickly aligned and inserted during installation. The supporting effect of the elastic protrusions and the inner wall of the positioning groove can achieve initial fixation, avoiding the need for continuous pressing or repeated tightening of bolts in traditional installation, and significantly shortening the assembly time.

[0012] The shape matching design of the mounting slot and the brush block, combined with the limiting effect of the positioning plate and the positioning groove, forms multiple anti-torsional constraints, which can effectively limit the circumferential rotation of the brush assembly during installation and operation, ensuring that the brush block and the commutator or slip ring always maintain the correct contact position, reducing the generation of sparks and abnormal wear caused by torsion, and improving the stability and safety of motor operation.

[0018] Please see Figure 1-4 ,

[0019] Example 1: An anti-twist quick-release brush grip includes a mounting post 1 and a brush assembly 2. The brush assembly 2 includes a brush block 3. One end surface of the brush block 3 is provided with a brush braid 4. A metal pressure plate 5 is fixedly installed at one end of the brush braid 4. A spring 6 is fixedly connected between the brush block 3 and the metal pressure plate 5. Two positioning plates 7 are fixedly connected to the lower surface of the metal pressure plate 5. The surfaces of the two positioning plates 7 are provided with locking components.

[0020] The upper end of the mounting post 1 is fixedly connected to the mounting block 8. The surfaces of the mounting block 8 and the mounting post 1 are provided with mounting grooves 9 that match the brush block 3. The upper surface of the mounting block 8 is provided with two positioning grooves 10 that match the positioning piece 7.

[0021] Example 2: The difference between this example and Example 1 is that the locking component includes protrusions 12 disposed on the surfaces of the two positioning pieces 7, and both protrusions 12 are made of elastic material.

[0022] Example 3: The difference between this example and Example 1 is that the upper part of the mounting block 8 is fixedly connected to the mounting sleeve 11, and the inner wall of the mounting sleeve 11 is provided with a threaded groove.

[0023] Example 4: The difference between this example and Example 1 is that the brush braid 4 is made of multiple strands of fine copper wire, and the brush block 3 is made of graphite material.

[0024] Example 5: The difference between this example and Example 1 is that the mounting post 1 and the mounting block 8 are both made of copper and their surfaces are covered with round tubes made of plastic or bakelite powder.

[0025] In summary, this anti-torsion quick-release brush grip allows for rapid installation. During installation, the brush block 3 of the brush assembly 2 is inserted into the mounting post 1 and the mounting groove 9 of the mounting block 8. Then, the two positioning pieces 7 are aligned with the two positioning grooves 10 on the mounting block 8. The metal pressure plate 5 is then pressed to insert the two positioning pieces 7 into the two positioning grooves 10 for initial positioning. Simultaneously, the protrusions 12 made of elastic material are pressed against the inner wall of the positioning grooves 10, providing a certain degree of fixation through friction. This prevents the brush from springing up after the metal pressure plate 5 is released, facilitating subsequent installation. This invention allows for quick installation and positioning of the brush assembly 2 during use, preventing it from springing up or twisting during installation, which would affect subsequent use.
