Description

Technical Field

[0001] This utility model relates to the field of wire brush technology, specifically a wire brush with a telescopic structure. Background Technology

[0002] A wire brush is a common cleaning and surface treatment tool widely used in industry, home, and handicrafts. It mainly consists of a wire and a handle. It removes stubborn dirt, rust, paint, or other surface residues through the hardness and friction of the wire. The wire is the core component of the wire brush and is usually made of high-carbon steel, stainless steel, or other alloy materials. The hardness, diameter, and length of the wire can be adjusted according to the intended use. The shape of the wire can be straight, curved, or wavy to suit different cleaning needs. The brush head is the fixed part of the wire, usually made of metal or plastic. The wire is fixed to the brush head by welding, pressing, or winding. The handle is the part that the user holds, and can be made of wood, plastic, or rubber. Some high-end wire brushes have ergonomically designed handles that provide a better grip and user comfort.

[0003] Existing wire brushes have a relatively simple structure and lack the function of adjusting the length of the wire brush. When using wire brushes to clean stubborn dirt and rust from higher places, they cannot completely remove the dirt and rust, leaving residual dirt and affecting the cleaning effect. Furthermore, the connection structure between the wire brush head and the brush handle of existing wire brushes is fixed, which cannot meet the replacement requirements of the corresponding wire brush head when it is necessary to replace it according to the cleaning needs, resulting in limitations in use. Therefore, a new technical solution needs to be designed to solve this problem. Utility Model Content

Through the telescopic mechanism, when using the wire brush to clean stubborn dirt and rust at higher locations, the telescopic mechanism can adjust the size of the dirt and rust according to its position. The position allows for flexible and quick adjustment of the wire brush length, facilitating the cleaning of stubborn dirt and rust at higher locations. The changing mechanism allows for rapid removal and replacement of the wire brush head as needed, enabling quick disassembly and installation of the desired head.

[0006] Preferably, the outer side of the main rod has a limiting groove, and the limiting grooves are arranged sequentially from top to bottom.

Detailed Implementation

[0021] 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.

[0022] Example 1: Please refer to again Figure 1-5 This utility model provides a wire brush with a telescopic structure, including a main rod 100, a sleeve rod 110 sleeved on the outer side of the main rod 100, a vertical groove 120 and a limiting groove 130 on the outer side of the main rod 100, and the limiting grooves 130 are arranged sequentially from top to bottom and are connected to the vertical groove 120. A first locking rod 140 is fixedly connected to the inner side of the sleeve rod 110, one end of the first locking rod 140 extends into the interior of the limiting groove 130. An installation sleeve 150 is fixedly connected to the outer side of the sleeve rod 110, and a limiting bolt 151 is screwed to one end of the installation sleeve 150. One end of the limiting bolt 151 passes through the sleeve rod 110 and extends into the interior of the main rod 100.

[0023] Specifically, when adjusting the length of the wire brush, the limiting bolt 151 is rotated to release the locking of the main rod 100 and the sleeve rod 110. Then, the main rod 100 is rotated to move the first locking rod 140 installed on the sleeve rod 110 from the limiting groove 130 to the vertical groove 120. The first locking rod 140 can then move up and down in the vertical groove 120. After moving the first locking rod 140 to the desired position, the main rod 100 is rotated again to move the first locking rod 140 into the limiting groove 130, where the limiting groove 130 limits the first locking rod 140. Finally, the limiting bolt 151 is tightened to lock the main rod 100 and the sleeve rod 110 after the length adjustment.

[0024] Example 2: Please refer to again Figure 1-5A mounting base 200 is provided above the main rod 100. The mounting base 200 is fixedly connected to the sleeve rod 110. The mounting base 200 has a mounting groove 210 inside. A compression spring 211 is fixedly connected to the bottom of the inner cavity of the mounting groove 210. A compression plate 220 is fixedly connected to the top of the compression spring 211. Through slots 230 are opened on both sides of the top of the mounting base 200. Slots 240 are opened on both sides of the top of the inner cavity of the mounting groove 210. The top of the mounting base 200 is inserted into... There is a friction pile 250, the bottom end of which extends into the inner cavity of the mounting groove 210 and contacts the extrusion plate 220. The outer side of the friction pile 250 contacts the mounting base 200. The outer sides of the friction pile 250 are fixedly connected to the second clamping rod 251, which is located inside the clamping groove 240 and is engaged with the clamping groove 240. The top of the friction pile 250 is fixedly connected to the wire brush head 260.

[0025] Specifically, when replacing the wire brush head 260, the friction post 250 is pressed down to compress the extrusion plate 220. This causes the extrusion spring 211 to deform, causing the second locking rod 251 on the friction post 250 to move downwards along with the friction post 250, moving from inside the slot 240 to below the slot 240. Then, the friction post 250 is rotated. As the friction post 250 rotates, it rubs against the mounting base 200, generating damping. When the second locking rods 251 on both sides move below the through slots 230 on both sides, the second locking rods 251 coincide with the through slots 230. The friction post 250 can then be removed from the mounting base 200, and the current wire brush head 260 can be disassembled. After unloading, align the friction post 250 at the bottom of the required wire brush head 260 with the mounting base 200 and insert it. Then, allow the second locking rods 251 on both sides to enter the mounting groove 210 through the through groove 230, causing the friction post 250 to press against the compression plate 220 and deform the compression spring 211. Next, rotate the friction post 250 to move the second locking rods 251 below the slot 240. Then, release the pressure on the friction post 250, allowing the compressed compression spring 211 to reset and push the compression plate 220 upwards. This causes the compression plate 220 to press against the friction post 250, allowing the second locking rods 251 to enter the slot 240. The slot 240, in conjunction with the second locking rods 251, limits the position of the friction post 250.

[0026] Working principle: When adjusting the length of the wire brush, the limiting bolt 151 is rotated to release the locking of the main rod 100 and the sleeve rod 110. Then, the main rod 100 is rotated to move the first locking rod 140 installed on the sleeve rod 110 from the limiting groove 130 to the vertical groove 120. The first locking rod 140 can then move up and down in the vertical groove 120. After moving the first locking rod 140 to the desired position, the main rod 100 is rotated again to move the first locking rod 140 into the limiting groove 130, where the limiting groove 130 limits the first locking rod 140. Finally, the limiting bolt 151 is tightened to lock the main rod 100 and the sleeve rod 110 after the length adjustment.

[0027] When replacing the wire brush head 260, the friction post 250 is pressed down to compress the extrusion plate 220. This causes the extrusion spring 211 to deform, causing the second locking rod 251 on the friction post 250 to move downwards along with the friction post 250, moving from inside the locking groove 240 to below the groove 240. Then, the friction post 250 is rotated. As the friction post 250 rotates, it rubs against the mounting base 200, generating damping. When the second locking rods 251 on both sides move below the through grooves 230 on both sides, their positions coincide with the through grooves 230. The friction post 250 can then be removed from the mounting base 200, and the current wire brush head 260 can be disassembled. Then, the friction post 250 at the bottom of the required wire brush head 260 is aligned with the mounting base 200 and inserted, so that the second locking rods 251 on both sides enter the mounting groove 210 through the through groove 230, causing the friction post 250 to press against the extrusion plate 220, causing the extrusion spring 211 to deform. Then, the friction post 250 is rotated so that the second locking rods 251 on both sides move below the slot 240. Then, the pressure on the friction post 250 is released, so that the extrusion spring 211 is reset and pushes the extrusion plate 220 upward, so that the extrusion plate 220 presses against the friction post 250, causing the second locking rods 251 on both sides to enter the slot 240. The slot 240, in conjunction with the second locking rods 251, limits the position of the friction post 250.
