Description

Adjustable rotary broom

Technical field

The utility model relates to rotary broom, specifically refers to a kind of adjustable angle formula rotary broom.

Background technology

Along with the development of construction craft technology and the variation of people's esthetic sentiment, increasing curved-surface building has appearred, especially the application in building production and petrochemical industry of steel structure truss and grid structure is very general, as gas station, bridge, airport lounge, terminal, station hall, chemical plant reaction tower device, pipe network or the like.To the brushing of this class formation, often all be in the subsequent step of engineering, to carry out, thus, when carrying out brushing paint with the rotary broom that is applicable to the brushing plane commonly used, effective contact area of cylinder and curved surface is very limited, and efficient is very low.

Chinese for this reason utility model patent ZL200720032202.X discloses " a kind of rotary broom ", comprise that support and brush roll, wherein said support is an arc-shaped structure, and the brush that also is provided with same structure in the support rolls bracing frame, and the brush that several brush roll sleeves are contained in this circular arc rolls on the bracing frame; And support and brush roll also to be provided with between the bracing frame and are used to regulate the bolt draw bar that brush rolls bracing frame.This patent is rolled bracing frame by brush and is set to arcuate structure, increases the contact area of rotary broom and curved-surface structure, thereby increases work efficiency.

It is certain that but support in this rotary broom and brush roll the curvature of bracing frame, that is to say, the building that this rotary broom was suitable for or the curvature of steel construction have certain restriction, more convenient when in the curvature scope of described support, using, then be difficult to be suitable for for building or steel construction less than the support curvature.

Summary of the invention

Technical problem to be solved in the utility model is the adjustable rotary broom that the suitable any curvature of a kind of energy is provided at the present situation of prior art.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this adjustable rotary broom comprises that the support that has handle, the pivot that is connected with support and ring set are on described pivot and round brush that can pivot relative, it is characterized in that: described pivot is made up of first pivot and second pivot, corresponding, round brush also has first round brush and second round brush to constitute, and an end of described first pivot and second pivot all is socketed on the described support, and also is provided with the position-limit mechanism of restriction first pivot and the second pivot rotational angle on described support.

Be respectively equipped with installing hole on one end of described first pivot and described second pivot, the inwall of described each installing hole is provided with internal tooth; The periphery wall of described support is provided with the external tooth that can be meshed with this internal tooth.

Above-mentioned intermeshing external tooth and internal tooth can be that external tooth is evenly arranged along the periphery wall of support, and this moment, described internal tooth can be one, can realize the step-less adjustment of angle; Perhaps internal tooth arranges evenly that along the inwall of installing hole external tooth is provided with one or more.Adopt all uniform structures on circumferential wall of internal tooth and external tooth, the fit structure of pivot and support is more stable.

For make first pivot and second pivot assembling after can be at grade, all have breach on the opposite face of one end of described first pivot and described second pivot, the position after an end of first pivot and second pivot is fitted has and described first pivot or the suitable periphery of second pivot.

Above-mentioned breach fit structure can also use groove, inserted block fit structure to replace, and promptly offers groove at an end of a pivot, and an end of another pivot is designed to the inserted block structure suitable with this groove.

Described support passes the part that exposes behind the described installing hole and has external screw thread, and described position-limit mechanism is this external screw thread and the bolt that is screwed on this external screw thread.

As the further improvement of such scheme, the outer wall of described first round brush, second round brush is the arc of indent respectively, and this structure is more suitable for the brushing of some curved-surface structures.

Compared with prior art, the utility model is designed to pivot on first pivot and second pivot that can rotate, by changing the relative angle of first pivot and second pivot, what can make the adaptive different curvature of rotary broom provided by the utility model treats the brushing thing, not only improved operating efficiency, and suitability is good.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

To shown in Figure 5, this adjustable cylinder comprises as Fig. 1:

Support 1, the end of one end has external screw thread 11, and the periphery wall of external screw thread 11 inboards is provided with external tooth 12.The other end of support 1 is connected with handle 2.If support is longer, also can save handle, directly support is used as handle.

Pivot, an end that comprises first pivot 31 and second pivot, 32, the first pivots 31 have on the opposite face of first breach, 311, the second pivots 32 and first pivot 31 and have second breach 321; Be respectively equipped with on first breach 311 and second breach 321 and be equipped with the internal tooth 313,323 that is meshed with external tooth 12 on the support on the internal perisporium of first installing hole 312 and second installing hole, 322, the first installing holes 312 and second installing hole 322.Position after first breach 311 and second breach 321 are fitted has and described first pivot 31 or the suitable periphery of second pivot 32.One end of support 1 passes first installing hole 312 and second installing hole, 322 its external screw thread 11 parts of back expose.

Round brush comprise first round brush 41 and second round brush, 42, the first round brush 41 and second round brush, 42 difference ring sets on first pivot 31 and second pivot 32, and the outer wall of first round brush 41 and second round brush 42 is the arc of indent respectively.

Bolt 5 is screwed on the external screw thread 11 of support.The position-limit mechanism that in external screw thread 11 and the bolt 5 common formation present embodiments two pivot rotational angles is limited.

This adjustable angle formula rotary broom can be brushed the brushing thing 6 for the treatment of of different curvature easily.Its concrete control method is as follows:

When needing to regulate the relative angle of first pivot 31 and second pivot 32, bolt 5 is backed out from support 1, then first pivot 31 and second pivot 32 are taken off from support, be installed on the support again according to the angle that is fit to then, make support pass first installing hole 312 and second installing hole 322, after internal tooth 313,323 and external tooth 12 engagements well, bolt 5 is tightened on external screw thread 11, can change the relative angle of first pivot 31 and second pivot 32, as shown in Figure 4 and Figure 5, so that suitable with the curvature for the treatment of brushing thing 6, as shown in Figure 6 and Figure 7.Obviously adopt such rolling brush, can increase work efficiency significantly.
