Abstract
The utility model discloses a noise-reduction drill bit of an electric drill. The noise-reduction drill bit comprises a drill bit top, a drill body and a drill tail, wherein the drill bit top is in a prism shape; the drill body is a hollow body; the hollow part is fully filled with noise-reduction materials; and the noise-reduction materials are macromolecular noise-reduction materials. The drill tail is provided with a mounting body. When the noise-reduction drill bit of the electric drill is used, noises are small and the body health of workers is not influenced.
Description
Technical field
The utility model relates to a kind of electric drill for wall boring, relates in particular to a kind of noise reduction drill bit for wall boring.
Background technology
In building field, often use electric drill and drill through hole at wall, in order to circuit is installed.Granted publication number is CN201970370U, Granted publication day is that the Chinese utility model on September 14th, 2011 discloses a kind of novel electric drill, comprise electric drill body, drill bit and storeroom, be characterized in that each electric drill body connects a drill bit, constitute a complete electric drill, a storeroom is installed on the electric drill body, and a plurality of standby drill bits of inner storage use the standby drill bit in the storeroom like this after a drill bit fracture.But this utility model noise in use is bigger, and workers with long time is in the environment of strong noise, greatly the influence of degree workman healthy.
The utility model content
In order to overcome above-mentioned defective, the utility model provides a kind of noise reduction drill bit, and this noise reduction drill bit is installed in when holing on the common electric drill, and noise is little, and the sound that sends does not influence the healthy of user in the decibel of safety.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
The noise reduction drill bit comprises the drill bit top, bores body and bores tail, and it is characterized in that: described drill bit top is prismatic, and described brill is as hollow body, and fills up acoustic damping materials at hollow position.
Described acoustic damping materials are the macromolecule acoustic damping materials.
Described brill tail is provided with fixing body.
The utlity model has following advantage:
The utility model is hollow body, fill up the acoustic damping materials that drill bit produces at hollow position, acoustic damping materials can absorb walks the noise that drill bit produces, and makes the sound of electric drill work generation at harmless safety decibel, the workman works under the environment in this and healthyly can not endangered, and work easily.The acoustic damping materials that the utility model is selected for use are that this acoustic damping materials not only aft mounted fixing body can allow drill bit be installed on the common electric drill.
Description of drawings
Fig. 1 is overall structure schematic diagram of the present utility model.
Mark 1, drill bit top among the figure, 2, bore body, 3, bore tail, 4, acoustic damping materials, 5, fixing body.
The specific embodiment
The utility model provides the noise reduction drill bit, comprises drill bit top 1, bores body 2 and bores tail 3, and it is characterized in that: described drill bit top 1 is prismatic, and described brill body 2 is hollow body, and fills up acoustic damping materials 4 at hollow position.
Described acoustic damping materials are the macromolecule acoustic damping materials.
Described brill tail 3 is provided with fixing body 5.
The utility model is hollow body, fill up the acoustic damping materials 4 that drill bit produces at hollow position, acoustic damping materials 4 can absorb walks the noise that drill bit produces, and makes the sound of electric drill work generation at harmless safety decibel, the workman works under the environment in this and healthyly can not endangered, and work easily.The acoustic damping materials that the utility model is selected for use are the macromolecule acoustic damping materials, and the fixing body that afterbody 3 arranges can allow drill bit be installed on the common electric drill.Drill bit 1 can allow drill bit creep into wall easily for prismatic, and is more laborsaving, thereby reduced expending of electric energy.
Claims (3)
1. the noise reduction drill bit comprises drill bit top (1), bores body (2) and bores tail (3), and it is characterized in that: described drill bit top (1) is prismatic, and described brill body (2) is hollow body, and fills up acoustic damping materials (4) at hollow position.
2. noise reduction drill bit according to claim 1, it is characterized in that: described acoustic damping materials (4) are the macromolecule acoustic damping materials.
