Detailed Implementation

[0049] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0050] Please see Figures 1 to 2 In this embodiment of the utility model, a multi-degree-of-freedom detachable cleaning brush includes:

[0051] Brush body 1; the brush body 1 is provided with a first limiting hole 101;

[0052] The first fixing bolt 8 mates with the first limiting hole 101;

[0053] At least one groove 103 is formed on the brush body 1;

[0054] A handle 5 is provided on the side of the brush body 1 away from the groove 103; the handle 5 coincides with the central axis of the brush body 1.

[0055] The working principle of this utility model is as follows: the brush head 11 is slidably installed inside the groove 103. There is at least one groove 103, and usually there are multiple grooves. After the brush head 11 is embedded in the groove 103, the first fixing bolt 8 is screwed into the first limiting hole 101. At this time, without the aid of other tools, the first fixing bolt 8 can be tightened directly by hand. The first fixing bolt 8 will increase the pressure between the inner wall of the groove 103 and the brush head 11, thereby increasing the friction, so that the brush head 11 is fixed in the groove 103. At this time, the user can hold the handle 5 and use the cleaning brush to perform cleaning work.

[0056] As a preferred embodiment of the present invention, the cleaning brush further includes a connecting component disposed between the brush body 1 and the handle 5; the connecting component includes:

[0057] The connecting frame 2 is connected to the brush body 1;

[0058] The tooth 201 is set at the end of the connecting frame 2 away from the brush body 1;

[0059] The adapter 4 is sleeved with the grip 5, and the end of the adapter 4 away from the grip 5 is provided with an external thread;

[0060] An adapter cylinder 3 is located at the end of the adapter 4 away from the handle 5. The side of the adapter cylinder 3 closest to the adapter 4 has an internal thread that mates with the external thread of the adapter 4. The side of the adapter cylinder 3 away from the adapter 4 has a toothed plate 301.

[0061] A rotating component is installed between the connecting frame 2 and the adapter cylinder 3.

[0062] Furthermore, the rotating component includes:

[0063] The tooth 201 is installed on the end of the connecting frame 2 away from the brush body 1;

[0064] A through hole is formed on the tooth plate 301, and the through hole is coaxial with the tooth head 201;

[0065] A limiting pin coaxial with the toothed head 201 and the through hole; the limiting pin includes a sleeved pin 6 and a plug 7.

[0066] In a preferred embodiment of this utility model, a connecting component is added between the brush body 1 and the handle 5. This connecting component has a rotation function, as detailed below:

[0067] The connecting frame 2 and the brush body 1 are fixedly connected. The tooth 201 at the end of the connecting frame 2 away from the brush body 1 is actually a fixed gear. On the other side, an adapter 4 is fitted onto the handle 5. The end of the adapter 4 away from the handle 5 has an external thread, and an adapter cylinder 3 is threaded onto the external thread. When the adapter 4 and the handle 5 rotate, the adapter 4 can move back and forth within the adapter cylinder 3. When the adapter 4 is deeper into the adapter cylinder 3, it will press the toothed plate 301, so that the toothed plate 301 engages with the tooth 201. At this time, the connecting frame 2 and the brush body 1 are in a fixed state relative to the handle 5. When the adapter 4 moves away from the adapter cylinder 3, the toothed plate 301 disengages from the tooth 2. At this time, the connecting frame 2 and the brush body 1 can rotate around the adapter 4 and the handle 5. This process also has an implicit meaning, that is, the connection between the tooth 201 and the adapter 4 is a rotating connection, and the rotating pair is a limiting pin composed of a pin 6 and a plug 7. Rotation and engagement or disengagement can achieve the desired angle for use.

[0068] In a preferred embodiment of this utility model, the cleaning brush further includes:

[0069] Ribs 10 are symmetrically arranged on both sides of the connecting frame 2, and the other end of the ribs 10 is connected to the brush body 1.

[0070] A second limiting hole 1001 is provided on the rib plate 10, which is coaxial with the first limiting hole 101.

[0071] A limiting platform 102 is set on the brush body 1;

[0072] The second fixing bolt 9 mates with the limiting platform 102.

[0073] In one embodiment of this utility model, in order to improve the stability of the cleaning brush, a rib plate 10 is provided between the connecting frame 2 and the brush body 1. The rib plate 10 greatly improves the stability of the cleaning brush. In addition, a limiting platform 102 is added to the brush body 1, and a second fixing bolt 9 is added to cooperate with the limiting platform 102. Since the second fixing bolt 9 is located on one side, its fixing flexibility is higher. Even if the brush head 11 is very short, it can be installed on one side of the brush body 1.

[0074] In addition, a second limiting hole 1001 coaxial with the first limiting hole 101 is added to the rib plate 10 to ensure that the fixing process of the first fixing bolt 8 can be carried out smoothly.

[0075] like Figures 3 to 7 As a preferred embodiment of the present invention, a multi-specification brush head is also provided. The multi-specification brush head is used for the multi-degree-of-freedom detachable cleaning brush. The brush head 11 includes a straight plate type and an L-shaped type. The brush head is fitted into the groove 103.

[0076] In a preferred embodiment of the present invention, the brush head 11 further includes a curved shape with a preset curvature angle.

[0077] In a preferred embodiment of the present invention, the brush head 11 further includes a splicing type, wherein one brush head 11 is welded to the bend of another curved brush head 11.

[0078] In a preferred embodiment of the present invention, the brush head 11 further includes a U-shape.

[0079] In one embodiment of this utility model, various shapes of the brush head 11 are provided. Some of these shapes are special shapes that require the cooperation of two fixing bolts of this utility model. If the first fixing bolt 8 can be used, the first fixing bolt 8 is used. If it cannot be used, it is installed on one side and the second fixing bolt 9 is used.

[0080] It is worth mentioning that the lengths of the two arms of the U-shaped brush head can be unequal, depending on the specific situation. Two short plates can also be welded at its bend. To ensure overall coordination, the two short plates can be welded to both sides of the brush head 11.

[0081] In addition, the length of the brush head 11 in this utility model is not limited. In fact, its length can be very long, such as a 2-meter straight board. The brush head 11 is selected by the staff according to the specific situation. The brush head 11 is composed of stainless steel sheet, ordinary sheet metal or flexible plastic sheet and bristles.

[0082] The brush head 11 can also include round and rectangular shapes. The key features are: first, its flexible structure, which can be freely bent into different shapes at multiple points; and second, its welding connection method, which allows a short brush head to be welded at multiple locations (especially at bending points) to increase the density of the bristles. In summary, the brush head 11 can be bent at any point. If the bending angle is too large, a short plate needs to be welded to prevent the bristles from being too sparse and affecting the cleaning effect.

[0083] It is worth mentioning that the bristles of the short brush head used for welding can be trimmed to make them flush with the bristles of the existing brush head 11. The angle before trimming can be a right angle or a preset arc, depending on the specific situation.

[0084] like Figure 8 As a preferred embodiment of this utility model, the user can unscrew the handle and attach the grip sleeve 12 to the end of the brush body 1 away from the limiting platform 12. At this time, by holding the grip sleeve 12, the user can directly pick up the brush body 1 for cleaning.

[0085] like Figure 9 As a preferred embodiment of this utility model, a brush body that can be directly held is also provided, called a handheld brush body 13. The handheld brush body 13 is provided with a through hole for connecting an external fixing component. At least one groove is provided on the handheld brush body, which corresponds to the brush body 1 and has a similar structure. The difference is that there is no need for an external handheld component, but the handheld part is integrally formed with the body.

[0086] Please see Figure 10 The brush head 11 of this utility model can be used independently and can be directly fixedly connected to a handheld component. Users can directly pick up the handheld component and use the brush head 11 to perform some cleaning work, which is extremely convenient.

[0087] Please see Figure 11 and Figure 12 This utility model also provides two composite structures, both of which are very low-cost cleaning brushes. They have another brush head 11 welded at the bend or joint to supplement missing bristles.

[0088] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0089] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
