Abstract
The present invention provides a hole-drilling dust-absorbing device for air conditioner installation, which relates to an auxiliary device of electric tools. The present invention is composed of a dust-absorbing cover with an opening at the front, a sealing rubber ring and a hollow tubular handle, wherein the tubular handle is communicated with the inner cavity of the dust-absorbing cover, and a joint connected with a dust-absorbing hose of the dust-absorbing device is arranged at the end of the tubular handle. A cushion is arranged at the front periphery of the dust-absorbing cover, and holes on the cushion are uniformly arranged within the 4/5 position of the upper part of the periphery. The dust-absorbing cover and the tubular handle are made of metal or plastic, and the sealing rubber ring is in a petal shape. The present invention can automatically absorb the dust and has the advantages of good dust-absorbing effect, convenient operation and long service life. The indoor and outdoor environment pollution can be avoided, and the health of operators can be protected. The present invention can be extensively applied to hole-drilling of air conditioner installation, and can also be matched with electric or pneumatic tools, such as impact drills, hand-held electric drills, pneumatic hammers, etc. The present invention can be universally applied to all engineering constructions needing hole drilling, such as household decoration, indoor rebuilding, electrical installation, pipe construction, gas supply, heat supply, water supply and drainage, etc.
Description
Technical field
The present invention relates to electric tool and auxiliary equipment thereof, the hole-drilling dust collector of the boring bar tools such as a kind of percussion drill that is used for occasions such as air-conditioner installation, electric hand drill of more clearly saying so.
Background technology
Detachable air conditioner, common cabinet air conditioner and central air-conditioning unit mostly have indoor set and off-premises station two parts, and the two connects with pipeline.During installation, want boring through walls inevitably.In the process of boring, the particle and the dust of cement, common brick, sandstone fly upward everywhere before.Inevitable ground contamination the environment of indoor and outdoor.Simultaneously, the operator has influenced health because of having sucked more dust.
For avoiding environmental pollution and protection operator's health, there is a kind of plastic cement dust cover that can be installed on the boring bar tool in the past, as the Chinese patent that the ZL00238237.7 name is called " percussion drill dust cover ".This class dust cover only is to cover the boring position, catches part dust passively, and is too simple.Need often outwell the dust in the cover during work, troublesome poeration, dustproof effect is limited, and easily broken ineffective.
Purpose of the present invention is to overcome above-mentioned shortcoming and defect, and a kind of dust suction on one's own initiative is provided; pick-up performance is good, and is easy to operate, long service life; both can avoid the environmental pollution of indoor and outdoor, can protect the hole-drilling dust collector for air conditioner installation of operator's health again.
Summary of the invention
In order to achieve the above object, the present invention includes the pipe handle of the narrow meshed dust shield in front openings top, connection hollow below dust shield.The dust shield back has the macropore on the drilling rod that can be sleeved on percussion drill.The aperture on dust shield top is distributed in its 4/5 position, circumferential periphery top, and middle O-ring seal with holes is installed in the macropore of dust shield back.These apertures are openings that air enters dust shield.Be distributed on its peripheral upper portion 4/5 position and can make steady air current, avoid turbulent flow, abate the noise, prevent that dust from leaking down from the hole.O-ring seal can be avoided the leakage that outer gas stream enters and inner dust is outside from the gap of dust shield and drilling rod.The flap O-ring seal is convenient to insert drilling rod, but excellent sealing again.Air is finally discharged through dust catcher.Pipe handle is communicated with the inner chamber of dust shield, and its end has the joint that can be connected with the hose of dust catcher.
Dust shield front periphery has cushion, is convenient to make it to fit with metope better, avoids dust to spill from its slit.Dust shield and pipe handle thereof are by metal or plastic production, and be durable in use, long service life.
During use, hand-held pipe handle is fitted in dust shield on the wall of desire boring, and the cushion that dust shield front periphery has plays sealing function.The hose of dust catcher is connected with the joint of pipe handle.Drilling rod with percussion drill inserts O-ring seal again.Start dust catcher then and percussion drill is started working.The dust that boring produces is closed in the dust shield, subsequently with being inhaled in the dust catcher by hose by dust shield opening inhaled air.
Task of the present invention comes to this and finishes.
The present invention is dust suction on one's own initiative, and pick-up performance is good.Easy to operate, long service life.Both can avoid the environmental pollution of indoor and outdoor, can protect operator's health again.It can be widely used in the boring of air-conditioner installation.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the A-A cutaway view of Fig. 1.
Schematic diagram when Fig. 3 is use.
Shown in Figure 1, the present invention is by the dust shield 2 on front openings top with holes 1, middle O-ring seal 3 with holes and be connected in that the pipe handle 4 of hollows is constituted below the dust shield 2.Pipe handle 4 is communicated with the inner chamber of dust shield 2, and its end has the joint 7 that can be connected with the hose 6 of dust catcher 5.Dust shield 2 front peripheries have cushion 8.Dust shield 2 and pipe handle 4 thereof are by metal or plastic production.
Shown in Figure 2, the hole 1 on dust shield 2 tops is distributed on its peripheral upper portion 2/3 position.O-ring seal 3 is a flap.
Shown in Figure 3, during boring, the pipe handle 4 of the hollow below the dust shield 2 is connected with the hose 6 of dust catcher 5.Dust shield 2 is fitted on the wall of desire boring, and the cushion 8 that the front periphery has plays sealing function.The drilling rod 10 of percussion drill 9 inserts O-ring seal 3 and enters in the wall 11.
The specific embodiment
Embodiment 1.A kind of hole-drilling dust collector for air conditioner installation, as shown in Figure 1.It is made of dust shield, O-ring seal and pipe handle.Pipe handle is communicated with the inner chamber of dust shield, and the end has the joint that can join with the hose of dust catcher.Dust shield front periphery has cushion, and the hole on its top is distributed on its peripheral upper portion 2/3 position.Dust shield and pipe handle thereof are by metal or plastic production.O-ring seal is a flap.Embodiment 1 dust suction on one's own initiative, pick-up performance is good.Easy to operate, long service life.Both can avoid the environmental pollution of indoor and outdoor, can protect operator's health again.It can be widely used in the boring of air-conditioner in installing.Also can be with percussion drill, electric hand drill, pneumatic hammer etc. electronic or pneumatic tool is supporting, all need in the engineering construction that holes through walls to be widely used in house decoration, indoor transformation, electric installation, pipeline construction and coal gas, heating, plumbing etc.
