Technical Field

The utility model relates to a dust keeper, specifically speaking are dust covers for cutting fitment lump material.

Background

In the construction process of Chinese buildings, large stone, wood or gypsum boards are often purchased directly from manufacturers and then cut or polished on construction sites due to the limitation of technology and cost conditions, so that a large amount of dust is generated on the construction sites, and the cutting and polishing operation is often processed indoors, so that the concentration of the dust in a relatively closed space is extremely high, the health of workers is greatly influenced, and occupational diseases such as respiratory tract infection are likely to be caused. And the worker works under the environment condition, the working efficiency is low, and the quality problem is easy to generate.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a dust cover for cutting decoration lump material to the solution cuts or when polishing the operation at the job site, and a large amount of dusts can disperse the problem in the air.

The utility model discloses a realize like this: a dust cover for cutting decoration lump materials comprises a square top plate, vertical plates enclosed on three sides of the top plate and a baffle plate enclosed on one side of the top plate without the vertical plates, wherein the baffle plate can rotate around a rotating shaft which is positioned at the upper end of the baffle plate and is vertical to the vertical plates on two sides of the baffle plate; when the baffle rotates along the rotating shaft, the studs positioned on two sides of the lower end of the baffle respectively slide in the strip-shaped holes of the corresponding side vertical plates.

The rotating shaft of the baffle is provided with cylindrical bulges at two sides of the upper end of the rotating shaft, and the cylindrical bulges are arranged in shaft grooves or shaft holes formed in vertical plates at two sides of the baffle in a penetrating manner.

The nut is a butterfly nut.

The utility model relates to a can be used to collect dust of handheld small-size cutting machine or polisher operation in-process, including setting up at the square roof on upper portion, enclose and close the riser on wherein trilateral of roof and enclose the baffle on one side of the not dress riser of roof, this baffle can be rotatory around its upper end's rotation axis, can adjust the rotation angle of baffle through the elasticity nut to make the better dust of collecting cutting machine or polisher operation in-process production of this dust cover.

The utility model discloses when using, at first lay the east and west that the one deck can wrap up the dust subaerial tie, like the felt, place this dust cover again on the felt of laying of collecting the dust, the operation direction of cutting machine or polisher is aimed at to the one side that is equipped with the baffle to make the dust that produces in the operation process enter into the dust cover through the baffle of the certain angle of slope, finally fall on the felt. Therefore, dust can be effectively prevented from entering the air, the concentration of the dust in the air is reduced, and the health of workers is protected. The utility model discloses simple structure, the flexible operation is convenient, can utilize the old and useless panel of job site, and goods and materials such as felt that the concrete curing was used make green.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

In the figure: 1. a vertical plate; 2. a strip-shaped hole; 3. a shaft hole; 4. a top plate; 5. a baffle plate; 6. a butterfly nut; 7. a stud.

Detailed Description

As shown in fig. 1, the present invention relates to a dust cover for collecting dust generated during operation of a small handheld cutting or grinding machine, which comprises a top plate 4, a vertical plate 1 and a baffle 5. The top plate 4 is square and arranged at the top, three vertical plates 1 are arranged and surround three sides of the top plate 4 to form an inverted dustpan-shaped structure. The baffle 5 is arranged around one side of the top plate 4 without the vertical plate 1, the baffle 5 can rotate and be positioned around the rotating shaft at the upper end of the baffle 5, and the axis of the rotating shaft is vertical to the plate surfaces of the vertical plates 1 at the two sides of the baffle 5.

The cylindrical protrusions are symmetrically arranged on two sides of the upper end of the baffle 5, the shaft holes 3 are formed in the vertical plates 1 on the corresponding sides of the cylindrical protrusions, the cylindrical protrusions are embedded on the vertical plates 1 on the corresponding sides respectively, and the baffle 5 can rotate due to the fact that the cylindrical protrusions play the role of a rotating shaft.

Arc-shaped strip holes 2 are symmetrically formed in the vertical plates 1 on the two sides of the baffle 5, studs 7 are arranged on the two sides of the lower end of the baffle 5, the studs 7 penetrate out of the strip holes 2 in the vertical plates 1 on the corresponding sides, and butterfly nuts 6 are screwed on the penetrating ends of the studs. When the baffle 5 rotates around the rotating shaft, the stud 7 at the lower end of the baffle 5 slides in the strip-shaped hole 2, and the butterfly nut 6 is screwed down to position the baffle 5. The inclination angle of the baffle 5 can be set by loosening and tightening the butterfly-shaped rotating nut 6 so as to meet the use requirements of the baffle 5 on different inclination angles.

The utility model discloses use with cloth or felt cooperation that the tiling is used for collecting the dust subaerial, use with the felt cooperation in this embodiment best. During the use, at first with the felt tiling treat the cutting or grind subaerial of material, then place this cover body on the felt that the tiling is good to the direction of making the one side of being equipped with baffle 5 aim at cutting machine or polisher operation, according to the direction and the height of dust during the operation, elasticity butterfly nut 6 adjusts baffle 5 to suitable inclination, alright cutting or grinding operation, in the cutting or grinding process, the dust can be followed baffle 5 and is located to enter into this cover body. After the operation of waiting to cut or polish is accomplished, remove this cover body and clear away the dust on the felt. The utility model discloses small and exquisite nimble, can effectually prevent splashing of dust, improve the environment of job site, protection staff's health.
