Description

Wall perforating device with dust absorption function

Technical Field

The utility model belongs to the technical field of the instrument for the decoration and specifically relates to a wall perforating device with dust absorption function.

Background

In the prior art, the wall is punched by an electric drill in the decoration process. And a drill bit is arranged on the electric drill, and the drill bit is used for punching on the wall surface. The in-process that punches can produce more dust and brick bits, cement bits etc. can fly off to the air under the effect of drill bit pivoted, causes the construction dust among the surrounding environment many, influences operation workman's health.

Particularly, when a hole is drilled in a ceiling, dust and the like generated by the hole can directly fall off, and an operator is often positioned below the hole and raises the head upwards, so that the dust easily falls off eyes and health and safety are affected.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve above-mentioned technique not enough and provide a wall perforating device with dust absorption function, can absorb the dust that produces among the drilling process to ensure that the dust is few among the operational environment.

The utility model discloses a wall perforating device with dust absorption function, including the electric drill body, be provided with the holder at the output of electric drill body, the holder is used for the fixed drill bit of centre gripping, is cylinder structure formation direction cylinder at the electric drill body that is close to holder one end, and sliding connection has the dust cover on the direction cylinder, the dust cover is the tubular structure, is provided with the locating part on the direction cylinder of keeping away from holder one end, is provided with the pressure spring between locating part and dust cover, is provided with out the dirt pipeline on the dust cover of keeping away from drill bit one end, is fixed with 2-4 blades on the circumference surface of holder, is provided with a plurality of fresh air inlet at the interval on the dust cover lateral wall of being close to drill bit one end.

According to the technical scheme, when the pressure spring is in a natural state, the end part of the dust cover is located on the outer side of the end part of the drill bit, namely, the drill bit is completely located inside the dust cover. In the drilling process, can be manual with the dust cover propelling movement backward for the tip of drill bit exposes in the dust cover outside, so that to the determination of the position of punching, after the location is accomplished, can loosen the dust cover, make the tip and the wall laminating of dust cover, start the electric drill body simultaneously, make the drill bit rotate, punch, in the drill bit rotation process, the holder rotates together, so the blade on the holder rotates equally, and the blast air direction of blade sets to: when the drill bit normally rotates, the blades blow air from the end part of the drill bit to one end of the dust outlet channel, so that in the drilling process, air outside the dust cover enters the dust cover through the air inlet hole and then drives dust to move to the dust outlet channel and convey the dust to the outside, and power of the dust outlet channel is driven by the power of the electric drill body. In the practical use process, the dust outlet pipeline can be connected with a hose to convey dust to a specified position, so that the environment of a drilling area is clean, and the dust is less. Above-mentioned scheme has the guard action simultaneously, can be with the whole dust cover that is located of drill bit among the drilling process inside, and operation process is safe and reliable more.

The dust cover of keeping away from drill bit one end is inside to be provided with the separation ring, sliding connection between separation ring and the guide cylinder keeps away from the dust cover tip of drill bit one end and the guide cylinder between sliding connection, the locating part sets up between the dust cover tip of keeping away from drill bit one end and separation ring, the pressure spring cup joints on the guide cylinder between locating part and separation ring, go out the dirt pipeline and set up on the dust cover of separation ring side, and go out the dirt pipeline and be located the both sides of separation ring respectively with the pressure spring. The design of this structure can be with parts such as pressure spring all assemble inside the dust cover to make the wholeness of equipment stronger, stability in the use is higher.

The utility model provides a wall perforating device with dust absorption function utilizes the dust cover and sets up the air formation directional air current in with the dust cover of fan on the holder, with the dust from the output of dust pipe way, ensures the clean of construction surrounding environment, and the dust is few.
