Abstract

The utility model discloses an inner wall cleaning brush that can uphold and contract, including first handle, terminal on the centre of first handle is fixed, be provided with the upper and lower gliding second handle of the outer wall that can follow last terminal in the outside of last terminal, set up the bracing piece in the inside of last terminal, the upper end and the second handle fixed connection of bracing piece, terminal is down fixed to the other end of bracing piece, being provided with at the bracing piece circumference with being evenly distributed and being no less than two sets of spring leafs, in the draw -in groove in the terminal was inserted to the one end of spring leaf, the other end was provided with the brush arm in inserting down the interior draw -in groove of terminal on the spring leaf, be provided with the brush hair on the brush arm. The utility model discloses a pulling force that the handle orientation will be followed through the spring leaf to the cleaning brush turns into the perpendicular to by cleaning surface's pressure, can adapt to the clean not object of equidimension internal diameter, and simultaneously, evenly distributed's brush arm can not be used in circular inner wall by the pressure cancel each other out of clear surface with equidirectional for convenient operation, it is clean high -efficient.

Description

A kind of inwall cleaning brush that can uphold and shrink

Technical field

The utility model relates to cleaning device, particularly relates to the cleaning device of clean inwall.

Background technology

At present, for the clean operation with circular inner wall article, as the inwall clean operation for circular pipe and circular dishware, conventional cleaning brush in use, for the circular inner wall stained surface of more difficult removal, needs slightly firmly to make the working surface of burnisher have good contact with decontamination surface, to reach good clean effect, because the working surface of cleaning brush and cleaned surface are that a direction is stressed, such clean operation not only efficiency is lower, and comparatively sweat.

Summary of the invention

The purpose of this utility model is for the deficiencies in the prior art, proposes the cleaning brush that a kind of convenience and high-efficiency cleans inwall.

The purpose of this utility model is achieved through the following technical solutions: a kind of inwall cleaning brush that can uphold and shrink, comprise first handle, upper terminal is fixed in the centre of first handle, the second handle that can slide up and down along the outer wall of upper terminal is had in the outer setting of upper terminal, in the inside of upper terminal, support bar is set, the upper end of support bar is fixedly connected with second handle, and the other end of support bar fixes lower terminal; Be provided with being evenly distributed at support bar circumference and be no less than two groups of spring leafs, one end of spring leaf is inserted in the draw-in groove in upper terminal, and the other end inserts in the draw-in groove in lower terminal, spring leaf is provided with brush arm, brush arm is provided with bristle.

Further, be 120 degree at support bar circumference and three groups of identical spring leafs are evenly set.

Further, described spring leaf is Ω shape spring leaf.

Further, described brush arm is circle flap.

The beneficial effects of the utility model are: the pulling force being parallel to circular inner wall direction to be converted into the pressure perpendicular to circular inner wall surface to be cleaned by spring leaf by the utility model cleaning brush, make operation more laborsaving, simple, and the internal diameter cleaning of the circular inner wall object of different inner diameters can be adapted to; Simultaneously, the bristle be evenly distributed owing to have employed at least two groups contacts with circular inner wall surface to be cleaned simultaneously, the pressure acting on circular inner wall surface to be cleaned of different directions can be cancelled out each other by the cleaning brush of this clean circular inner wall, therefore, makes clean operation further easy to be laborsaving.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail

As Figure 1-4, a kind of inwall cleaning brush that can uphold and shrink of the utility model, comprise: first handle 1, screwed hole is provided with in the centre of first handle 1, one end of upper terminal 10 is provided with screw thread corresponding with it, upper terminal 10 is screwed in first handle 1 and upper terminal 10 and first handle 1 are fixed as one; The second handle 2 that can slide up and down along the outer wall of upper terminal 10 is had in the outer setting of upper terminal 10, in the inside of upper terminal 10, support bar 8 is set, the upper end of support bar 8 and second handle 2 are fixed by screw 9, make second handle 2 and support bar 8 can together with move up and down along the direction perpendicular to upper terminal 10 cross section; The other end of support bar 8 is provided with lower terminal 6, lower terminal 6 is fixedly connected with support bar 8 by hold-down nut 5, be provided with being evenly distributed at support bar 8 circumference and be no less than two groups of spring leafs, one end of spring leaf is inserted in the draw-in groove in upper terminal 10, the other end inserts in the draw-in groove in lower terminal 6, spring leaf is provided with brush arm 3, brush arm 3 is provided with bristle 7.

Preferably, be 120 degree at support bar 8 circumference and three groups of identical Ω shape spring leafs 4 are evenly set, fix a brush arm 3 often organizing Ω shape spring leaf 4 centre position.Can dock better to make cleaning brush of the present utility model three groups of brush arms 3 when contraction state, brush arm 3 can be arranged to circle flap, so both facilitated depositing of whole cleaning brush, both artistic and practical again, whole cleaning brush can also be used as cleaning rod to use when cleaning brush closes.

For the ease of production and processing, brush arm 3 can adopt working of plastics, and bristle 7 can select sponge block; Spring leaf can be arranged to Ω shape, when not being subject to the pulling force of first handle 1 and second handle 2, cleaning brush is closure state, when first handle 1 and second handle 2 are subject to external force close to each other, support bar 8 pulls lower terminal 6 close to upper terminal 10, Ω shape spring leaf 4 is stressed to arch upward to the outside, drives the brush arm on Ω shape spring leaf 4 to open outside 3.

To cleaned object 10 carry out inwall clean time, brush arm 3 can be stretched to the surface of inwall required cleaning, one holds cleaned object 10, another holds first handle 1, thrust out one's fingers simultaneously and gently draw second handle 2, second handle 2 starts to move to first handle 1 direction, pulling force is passed to brush arm 3 by spring leaf, when pointing the suitable pulling force of applying and making the cleaned surface of brush arm 3 and circular inner wall contact and produce suitable pressure, stop finger pulling action, rotate or the cleaning brush that swings back and forth, clean to satisfaction.Apply the identical pressure of size owing to have employed three groups of bristles be evenly distributed 6 with the cleaned surface of circular inner wall simultaneously, the pressure acting on the cleaned surface of circular inner wall of different directions can be cancelled out each other, therefore, make clean operation easier to be laborsaving.
