Description

Technical Field

[0001] This utility model relates to the field of brush clamping technology, specifically a universal clamp for clamping brushes. Background Technology

[0002] Brushes are used to clean dust, but shorter brushes are difficult to clean dust in higher places. Therefore, it is necessary to attach a longer handle to the brush to clean dust in higher places.

[0003] Application No. 201921764287X discloses a brush handle clamping device, including a mounting base plate. A fixed clamping member is provided on one side of the upper surface of the mounting base plate and is fixed to the mounting base plate. An upper clamping member is provided at the upper end of the fixed clamping member, and one end of the upper clamping member is rotatably connected to the fixed clamping member through a rotating shaft. The other end of the upper clamping member is fixedly connected to the fixed clamping member by screws. A movable clamping member is provided on the other side of the upper surface of the mounting base plate. The movable clamping member includes a movable seat and a slider is provided at the lower end of the movable seat. The slider and the movable seat are integrally formed. Two sliding grooves are provided in the middle of the upper surface of the mounting base plate. The mounting base plate and the movable clamping member are slidably connected through the sliding grooves and the slider.

[0004] While the aforementioned existing technology can clamp the brush, the clamping device is relatively complex, resulting in device instructions and an inability to adjust the brush's angle of use. Utility Model Content

[0015] 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.

[0016] Example: Please see Figures 1 to 3 This utility model provides a technical solution: A universal gripper for holding a brush includes a mounting sleeve 1, an angle adjustment assembly 2, a connecting handle 3, and a fixing assembly, wherein: The mounting sleeve 1 is equipped with a fixing component for securing the brush; the brush handle can be inserted into the mounting sleeve 1, and then the brush can be secured by the fixing component. The connecting handle 3 is rotatably mounted on the mounting sleeve 1 for mounting the brush via the angle adjustment component 2. The angle adjustment component 2 is used to adjust the angle between the connecting handle 3 and the mounting sleeve 1, thereby facilitating the adjustment of the brush's operating angle when cleaning dust.

[0017] In a preferred embodiment, the angle adjustment assembly 2 includes an annular serrated portion 21 and a locking bolt 22. Both the mounting sleeve 1 and the connecting handle 3 are provided with annular serrated portions 21, and these portions are in contact with each other. The locking bolt 22 passes through the connecting handle 3 and is rotatably mounted on the mounting sleeve 1. The locking bolt 22 and the mounting sleeve 1 are threaded together, and the pressing surface of the locking bolt 22 contacts the connecting handle 3. Rotation of the locking bolt 22 can press the mounting sleeve 1 and the connecting handle 3 together, thus restricting rotation between them.

[0018] In a preferred embodiment, in order to facilitate the connection of the handle 3 to the external long handle, the other end of the handle 3 is provided with a threaded connection part, and the handle 3 and the long handle are connected by a threaded engagement.

[0019] In a preferred embodiment, the fixing component is a clamping bolt 4, which is threaded into the mounting sleeve 1. The other end of the clamping bolt 4 is used to clamp the connecting part of the brush. When the brush handle is inserted into the mounting sleeve 1, the clamping bolt 4 is rotated, causing the clamping bolt 4 to clamp the brush handle. Under the combined action of the inner wall of the mounting sleeve 1 and the clamping bolt 4, the brush can be fixed.

[0020] In a preferred embodiment, the fixing components are a clamping part 51 and a driving part. The mounting sleeve 1 is arranged in a circumferential array with at least three clamping parts 51, wherein the clamping end of the clamping part 51 is located inside the mounting sleeve 1, and the driving part is provided on the mounting sleeve 1 to drive the clamping end of the clamping part 51 to move synchronously.

[0021] In a preferred embodiment, the clamping part 51 includes an arc-shaped slider 511, a connecting rod 512, and a pressing part 513 as the clamping end. The arc-shaped slider 511 is movably mounted on the mounting sleeve 1 and forms a linear motion pair in the direction of the central axis of the mounting sleeve 1. The two connecting rods 512 are hinged to each other, with the other end of one connecting rod 512 hinged to the arc-shaped slider 511 and the other connecting rod 512 hinged to the mounting sleeve 1. The pressing part 513 is provided at the hinge point of the two connecting rods 512. Pushing the arc-shaped slider 511 causes the two hinged connecting rods 512 to move closer to each other, which can drive the pressing part 513 to move in the direction of the central axis of the mounting sleeve 1. This can squeeze the handle of the brush and achieve the purpose of fixing the brush.

[0022] In a preferred embodiment, the driving unit is a push sleeve 52, which is threaded onto the mounting sleeve 1 and contacts the arc-shaped slider 511. Rotating the push sleeve 52 can push all the arc-shaped sliders 511, causing the two hinged connecting rods 512 to move closer to each other.

[0023] The working principle of this utility model: When you need to use a brush to clean dust from high places, insert the brush handle into the mounting sleeve 1, and then fix the brush in place using the fixing components.

[0024] When the fixing component is the clamping bolt 4, simply rotate the clamping bolt 4 so that it clamps the handle of the brush. Under the combined action of the inner wall of the mounting sleeve 1 and the clamping bolt 4, the brush can be fixed.

[0025] When the fixing components are the clamping part 51 and the driving part, rotating the push sleeve 52 can push all the arc-shaped sliders 511 to bring the two hinged connecting rods 512 closer together. This, in turn, can drive the squeezing part 513 to move towards the central axis of the mounting sleeve 1, thus squeezing the brush handle and fixing the brush.

[0026] After the brush and mounting sleeve 1 are fixed in place, adjust the angle between the mounting sleeve 1 and the connecting handle 3. Then, rotate the locking bolt 22 to tighten the mounting sleeve 1 and the connecting handle 3, thus restricting their rotation. Then, attach a long handle to the connecting handle 3 to clean higher areas.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
