Description

A kind of wall surface grinding machine head and the wall surface grinding machine with the head

Technical field

The utility model is related to a kind of sander, more particularly to a kind of wall surface grinding machine head and the metope with the head Sander.

Background technology

Wall surface grinding machine be it is a kind of convenient for people paint, lay paint on the wall or sticking wallpaper before polish wall and Clean tool is widely used in construction and decoration field at present.

Existing wall surface grinding machine referring to Fig. 7, including wall surface grinding machine head 1, is installed on wall surface grinding machine head 1 Mounting base 2, the motor 3 being set in mounting base 2 and the handle 4 being articulated in mounting base 2, wall surface grinding machine head 1 wrap Protective cover 11 is included, the lighting mechanism 12 of 11 side of protective cover annular shape is installed on and is threaded onto the polishing pad of 11 bottom of protective cover (not shown), protective cover 11 include shield ontology 111 and the arc-shaped cover 112 for being connected in 111 side of shield ontology.Unload arc When shape cover 112, polishing pad can be more close to wall inner corner trim, to facilitate polishing.

However, the wall surface grinding machine is practical when dismantling arc-shaped cover 112, circular lighting mechanism 12 is set to protective cover 11 side makes the radial width of arc-shaped cover 112 limited, so that operating personnel hold more inconvenience, reduces arc-shaped cover 112 removal efficiency.

Utility model content

First purpose of the utility model is to provide a kind of wall surface grinding machine head, and which solve the polishings of existing metope Machine head holds inconvenient problem when dismantling arc-shaped cover.

The above-mentioned technical purpose of the utility model technical scheme is that：

A kind of wall surface grinding machine head, including protective cover, be installed on the lighting mechanism of protective cover side and be threaded onto anti- The polishing pad of shield bottom, the protective cover include shield ontology and are connected in the arc of shield ontology side by snap component Cover, the lighting mechanism include the lamp strip assembly for positioning ring seat and being installed in positioning ring seat, and positioning ring seat includes being set to shield Main paragraph of the ontology connecting the evacuation section of the arc-shaped cover side and set on the shield ontology other side.

Using the above scheme, evacuation section is set to shield ontology in the side of connection arc-shaped cover, with this convenient for increase arc The radial width of cover increases operating personnel and holds area, wall surface grinding machine is facilitated to be torn open to arc-shaped cover when polishing metope inner corner trim It unloads, to increase the working efficiency of operating personnel；In addition, main paragraph remain unchanged positioned at protective cover outside, and arc-shaped cover relative to Shield ontology accounts for smaller, and then reduces influence of the setting evacuation section to the range of exposures of lamp strip assembly so that light bar mechanism Still there is good illuminating effect, personnel easy to operation more rapidly, to be accurately observed, increase the effect of metope polishing, Have the characteristics that simple in structure, easy to operate.

Further preferably：The evacuation section is connected to one end of main paragraph and forms one in one end of the arc-shaped cover Port.

Using the above scheme, it is usual two connection structures between its connection corner or end structural stability compared with Difference avoids section and main paragraph and forms port in one end of arc-shaped cover so that and the end of arc-shaped cover has larger gripping area, with This improves the working efficiency of operating personnel convenient for accelerating the dismounting of arc-shaped cover；In addition, the setting of through-hole be also convenient for positioning ring seat from The side of protective cover is disassembled and installed, its installation effectiveness is increased.

Further preferably：The evacuation section includes that the bending part being connect with the main paragraph, one end and bending part connect Curved portion and the folding portion that connect and be located in the port with the curved portion other end.

Using the above scheme, bending part is the buffer locations for avoiding section and being connect with main paragraph, while can also be in arc-shaped cover End forms a turning so that the end of arc-shaped cover has larger gripping area, and then personnel easy to operation are to arc-shaped cover Dismounting；Curved portion enables to evacuation section close toward the edge of protective cover as possible, increases the radiation response of lamp strip assembly with this； Folding portion can supplement the light of port, increase the illuminating effect of lighting mechanism.
