Description

Technical Field

[0001] This utility model relates to the field of electrical equipment maintenance tools, and in particular to an electrical cleaning brush. Background Technology

[0002] During the maintenance of primary electrical equipment in hydropower plants, cleaning is crucial. However, existing cleaning tools have many shortcomings when dealing with narrow and confined spaces. Moreover, traditional brushes have fixed lengths and angles, making it difficult to flexibly adapt to various complex spatial structures. Utility Model Content

[0003] To address the aforementioned technical problems, this application provides an electric cleaning brush. The overall length of the brush is adjustable via a retractable handle, and the angle between the brush head and the retractable handle can be adjusted via a flexible metal tube to meet the cleaning needs under different working conditions. To achieve the above technical features, the purpose of this utility model is as follows:

[0004] An electric cleaning brush includes a handle and a brush head;

[0005] The brush handle includes a retractable handle, one end of which is connected to a metal shaping hose, and one end of which is connected to the brush head.

[0006] The retractable handle includes a first rod, a second rod is fitted inside the first rod, the second rod is connected to the metal shaping hose, and a locking device is provided between the first rod and the second rod to lock the relative position between the first rod and the second rod.

[0007] The locking device includes a mounting base fixedly connected to the first rod body at one end. The inner cavity of the mounting base has a structure that is larger at the upper end and smaller at the lower end. A conical sleeve is fitted inside the inner cavity. The upper and lower ends of the conical sleeve are respectively provided with a first longitudinal opening and a second longitudinal opening in annular shape, and the first longitudinal opening and the second longitudinal opening are distributed at intervals. A locking sleeve is screwed onto the other end of the mounting base. The upper end of the locking sleeve and the upper end of the conical sleeve form an axial limit. The conical sleeve is fitted onto the outside of the second rod body.

[0008] The upper end of the locking sleeve abuts against the upper end of the conical sleeve.

[0009] The upper end of the locking sleeve is provided with an annular groove, and the inner wall of the upper end of the locking sleeve is provided with a protruding ring that cooperates with the annular groove.

[0010] The upper end of the locking sleeve abuts against the upper end of the conical sleeve. The upper end of the locking sleeve is provided with an annular groove, and the inner wall of the upper end of the locking sleeve is provided with a protruding ring that cooperates with the annular groove.

[0011] The brush head is detachably connected to the metal shaping hose. There are multiple brush heads, and each brush head is of a different type to meet the needs of different working conditions.

[0012] The outer side of the first rod is fitted with an anti-slip sleeve.

[0013] The present invention has the following beneficial effects:

[0014] 1. The retractable handle allows for adjustment of the overall length of the brush to accommodate use in narrow spaces. The flexible metal tube can be bent and oriented in any direction to adjust the angle between the brush head and the retractable handle, while also allowing for deformation of the brush handle to further meet the cleaning needs in special working conditions such as corners.

[0015] 2. During the locking operation, the axial force is generated by manually screwing in the locking sleeve, which drives the tapered sleeve to move downward along the axial direction, causing the tapered sleeve to retract inward. The inner wall of the tapered sleeve is tightly clamped to the outside of the second rod body, thus achieving locking. The above locking structure is stable and reliable. When the locking sleeve is manually loosened, the convex ring transmits an upward pulling force, which drives the tapered sleeve to move upward along the axial direction to quickly release the lock.

[0016] 3. The brush head is detachably connected to the metal shaped hose. There are multiple brush heads, and each brush head is of a different type. Different working conditions can be met by changing the brush head. Attached Figure Description

Detailed Implementation

[0022] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0023] To achieve the above-mentioned technical features, the purpose of this utility model is as follows:

[0024] See appendix Figure 1-3 An electric cleaning brush includes a handle 1 and a brush head 2. The handle 1 includes a telescopic handle 1a, one end of which is connected to a metal flexible tube 1b, and the other end of which is connected to the brush head 2. The telescopic handle 1a allows for adjustment of the overall length of the brush, facilitating use in narrow spaces. The metal flexible tube 1b, also known as a gooseneck tube, allows for bending and directional adjustment of the angle between the brush head 2 and the telescopic handle 1a, while also enabling local deformation of the handle to further meet cleaning needs in special conditions such as corners.

[0025] Furthermore, the retractable handle 1a includes a first rod 1a1, a second rod 1a2 is fitted inside the first rod, the second rod 1a2 is connected to the metal shaping hose 1b, and a locking device 3 is provided between the first rod 1a1 and the second rod 1a2, the locking device 3 being used to lock the relative position between the first rod 1a1 and the second rod 1a2.

[0026] Furthermore, the locking device 3 includes a mounting base 3a fixedly connected to the first rod body at one end. The inner cavity 3a1 of the mounting base 3a has a structure that is larger at the upper end and smaller at the lower end. A conical sleeve 3b is fitted inside the inner cavity 3a1. The upper and lower ends of the conical sleeve 3b are respectively provided with a first longitudinal opening 3b1 and a second longitudinal opening 3b2 in annular shape, and the first longitudinal opening 3b1 and the second longitudinal opening 3b2 are spaced apart from each other. A locking sleeve 3c is screwed onto the other end of the mounting base 3a. The upper end of the locking sleeve 3c and the upper end of the conical sleeve 3b form an axial limit. The conical sleeve 3b is fitted onto the outside of the second rod body 1a2. When performing the locking operation, the axial force is generated by manually screwing in the locking sleeve 3c, which drives the conical sleeve 3b to move downward along the axial direction, causing the conical sleeve 3b to retract inward. The inner wall of the conical sleeve is tightly clamped to the outside of the second rod body, thereby achieving locking. The above locking structure is stable and reliable.

[0027] In one embodiment, the upper end of the locking sleeve 3c abuts against the upper end of the conical sleeve 3b. By manually screwing the locking sleeve 3c in, the conical sleeve 3b is driven to move downward along the axis, thereby achieving the clamping action.

[0028] In one embodiment, the upper end of the conical sleeve 3b is provided with an annular groove 3b3, and the inner wall of the upper end of the locking sleeve 3c is provided with a convex ring 3c1 that cooperates with the annular groove 3b3. By setting the annular groove 3b3 and the convex ring 3c1, the conical sleeve 3b can be moved downward along the axial direction by manually screwing in the locking sleeve 3c, thereby achieving a clamping action. At the same time, when the locking sleeve 3c is manually loosened, the convex ring 3c1 transmits an upward pulling force, causing the conical sleeve 3b to move upward along the axial direction, thereby quickly releasing the lock.

[0029] In one embodiment, the upper end of the locking sleeve 3c abuts against the upper end of the conical sleeve 3b. The upper end of the locking sleeve 3c is provided with an annular groove 3b3, and the inner wall of the upper end of the locking sleeve 3c is provided with a convex ring 3c1 that cooperates with the annular groove 3b3. During the locking operation, since a relatively large pushing force is required to make the conical sleeve 3b retract, the locking sleeve 3c is manually screwed in, and the inner end face of the locking sleeve 3c drives the conical sleeve 3b to move downward along the axial direction to achieve the clamping action. At the same time, when the locking sleeve 3c is manually loosened, the upward pulling force transmitted by the convex ring 3c1, combined with the internal force of the deformation of the conical sleeve 3b, drives the conical sleeve 3b to move upward along the axial direction to achieve the unlocking.

[0030] Different types of electrical equipment surfaces require different sizes of brushes for cleaning. For example, small, delicate areas require small brushes, while large areas require slightly larger brushes. Some equipment surfaces have special materials that require harder brushes to remove stubborn stains. As one implementation method, in this embodiment, the brush head is detachably connected to a metal shaped hose. There are multiple brush heads, and each brush head 2 is of a different type. By changing the brush head, different working conditions can be met. Preferably, the brush head 2 is connected to the metal shaped hose 1b by threads.

[0031] In one embodiment, the first rod 1a1 is fitted with a non-slip sleeve 4 made of rubber material on its outer side for easy gripping.
