Description

Technical Field

[0001] This utility model belongs to the field of building decoration technology, specifically relating to a dust-reducing and noise-reducing drilling device for one-time forming of decorative holes in walls. Background Technology

[0002] In the field of structural decoration, with the continuous emergence of new wall panel materials and components, such as lightweight composite wall panels and fiber cement boards, these new wall panels have many advantages in structural decoration performance. However, these panels also place higher demands on drilling operations. Traditional drilling devices, such as ordinary electric drills, require marking lines on the wall surface for positioning during drilling. Drilling also generates dust and noise in the air, and the drill bit's direction is prone to deviation. When drilling non-circular holes (such as quincunx-shaped holes), multiple drilling attempts and secondary repairs are often required. Therefore, to reduce dust and noise pollution and achieve one-time forming of decorative holes with special shapes on the wall surface, it is necessary to design a drilling device to solve the above technical problems. Utility Model Content

[0003] The technical problem solved by this utility model is to provide a dust-reducing and noise-reducing drilling device for one-time forming of decorative holes in walls. By optimizing the structure of the connection position of the handheld drill bit, a structure is set on the electric drill body with a laser sensing device at the top, in which the internal motor drives the combined drill bit to rotate and drill. This achieves simultaneous drilling of the combined drill bit and the laser sensing device determining the hole position, thus completing the one-time forming of plum blossom-shaped decorative holes. By setting a dust collection and noise reduction device on the electric drill body, the effects of reducing dust and noise pollution are achieved. The structure is simple, the positioning is accurate, the edges are neat, pollution is reduced, the forming effect is good, the quality is high, and no secondary repair is required.

[0004] The technical solution adopted in this utility model is as follows: a dust-reducing and noise-reducing drilling device for one-time forming of decorative holes in walls, including an electric drill body. A combined drill bit is provided on the outer side of the left end face of the electric drill body, and the combined drill bit is connected to a motor inside the electric drill body through a transmission component. The motor drives the combined drill bit to rotate through the transmission component. A dust-collecting and noise-reducing device is provided on the left end of the electric drill body to cover the combined drill bit and keep it in contact with the wall surface to collect dust during the drilling process. The exposed length of the combined drill bit is adjusted by adjusting the length of the dust-collecting and noise-reducing device. A laser sensing device is installed on the top of the electric drill body for measuring and displaying the longitudinal and transverse coordinate data of the aiming point on the wall.

The fixed rods on the right ends of the multiple driven gears are respectively adapted to and inserted into internal hexagonal bearings evenly distributed around the outer circumference of the rotating shaft and rotatably mounted on the left end face of the drill body. The transmission assembly is adapted to and connected to the gear rods on the left end faces of the driving gear and the multiple driven gears, and under the drive of the motor inside the drill body, realizes the rotational drilling of the combined drill bit.

[0006] Furthermore, the combined drill bit includes a central drill bit and edge drill bits evenly distributed around the outer periphery of the central drill bit.

[0007] Furthermore, a gap is provided between the intermediate drill bit and the multiple edge drill bits.

[0008] Furthermore, the dust collection and noise reduction device includes a hollow dust collection sleeve with openings at both the left and right ends, and a sound insulation and noise reduction pad fixed to the outer circumferential wall of the dust collection sleeve. A guide ring plate located at the right end and a guide baffle located to the left of the guide ring plate are fixed on the inner wall of the dust collection sleeve. Two vertically distributed sliding grooves are symmetrically formed on the surface of the guide ring plate and the guide baffle. A fixed sleeve is fixed to the left end of the electric drill body, and vertically distributed guide rails are symmetrically provided on the outer wall of the fixed sleeve.

[0024] A dust-reducing and noise-reducing drilling device for one-time forming of decorative holes in walls, such as... Figure 1-5 As shown, the device includes a drill body 1. A combined drill bit is mounted on the outer left side of the drill body 1. The combined drill bit is connected to a motor inside the drill body 1 via a transmission assembly, and the motor drives the combined drill bit to rotate via the transmission assembly. A dust collection and noise reduction device is located at the left end of the drill body 1, which houses the combined drill bit and keeps it in contact with the wall surface during drilling to collect dust. The exposed length of the combined drill bit is adjusted by adjusting the length of the dust collection and noise reduction device. A device is mounted on the top of the drill body 1 for measuring and displaying the longitudinal and transverse coordinates of the aiming point on the wall. The laser sensing device 4 is specifically a laser infrared rangefinder. Under the action of the laser infrared rangefinder, the longitudinal and transverse coordinate data of the aiming point on the wall are measured and displayed to locate the opening position. In the above structure, by optimizing the structure of the connection position of the hand drill bit, a structure is set on the electric drill body 1 by the internal motor driving the combined drill bit to rotate and drill through the transmission component. By using the synchronous drilling of the combined drill bit, the plum blossom-shaped decorative hole is formed in one step, which solves the drawbacks of traditional hand drills that require multiple drilling and multiple repairs.

[0025] like Figure 2 , 3As shown, the specific structure of the transmission assembly is as follows: The transmission assembly includes a driving gear 10 and multiple driven gears 12 evenly distributed around the outer circumference of the driving gear 10 and meshing with the driving gear 10. A gear rod 15 with a long key on its outer wall is centrally fixed to the left end face of both the driving gear 10 and the driven gear 12, and a fixed rod 16 with a polygonal cross-sectional shape is centrally fixed to the right end face of the driven gear 12. Figure 5 As shown, the rotating shaft 9 with a long key on the motor inside the electric drill body 1 is adapted to be connected to the central shaft hole with a keyway hole on the right end face of the driving gear 10. The fixing rods 16 on the right end of the multiple driven gears 12 are respectively adapted to be inserted into the internal hexagonal bearings 6 that are evenly distributed around the outer circumference of the rotating shaft 9 and rotatably installed on the left end face of the electric drill body 1. The transmission assembly is adapted to be connected to the gear rods 15 on the left end face of the driving gear 10 and the multiple driven gears 12, and realizes the rotation drilling of the combined drill bit under the drive of the motor in the electric drill body 1.

[0026] like Figure 2 , 3 As shown, the specific structure of the combined drill bit is as follows: The combined drill bit includes a central drill bit 11 and edge drill bits 13 evenly distributed around the outer periphery of the central drill bit 11. The slot 17 with a keyway on the right end face of the central drill bit 11 is adapted to be connected to the gear rod 15 on the left end of the drive gear 10, and the slot 17 with a keyway on the right end face of the edge drill bits 13 is adapted to be connected to the gear rod 15 on the left end of the driven gear 12. Specifically, there is a gap between the central drill bit 11 and the multiple edge drill bits 13. The setting of this gap can not only avoid mutual interference between the drill bits, but also allow the debris entering between the drill bits to be crushed again in the gap and discharged outward. When the combined drill bit needs to rotate, the rotating shaft 9 drives the drive gear 10 to rotate, the drive gear 10 drives the five driven gears 12 around it to rotate, the drive gear 10 drives the central drill bit 11 to rotate, and the driven gears 12 drive the edge drill bits 13 to rotate, so that the central drill bit 11 and the five edge drill bits 13 can drill at the same time.

[0027] like Figure 4As shown, the specific structure of the dust collection and noise reduction device is as follows: The dust collection and noise reduction device includes a hollow dust collection sleeve 7 with openings at both the left and right ends, and a sound insulation and noise reduction pad 8 fixed on the outer circumferential wall of the dust collection sleeve 7. A guide ring plate 19 located at the right end and a guide baffle 20 located on the left side of the guide ring plate 19 are fixed on the inner wall of the dust collection sleeve 7. Two vertically distributed sliding grooves 18 are symmetrically formed on the surface of the guide ring plate 19 and the guide baffle 20. A fixing sleeve 14 is fixed at the left end of the electric drill body 1, and a vertically distributed guide rail 5 is symmetrically formed on the outer wall of the fixing sleeve 14. The dust collection sleeve 7 is fitted onto the fixing sleeve 14, and the combined drill bit passes through the guide ring plate 19 and multiple through holes provided on the guide baffle 20. The sliding grooves 18 on the guide ring plate 19 and the guide baffle 20 are connected to the fixing sleeve 14. The guide rail 5 at the corresponding position on the fixed sleeve 14 is adapted, and dust collection and noise reduction protection is provided when the dust collection sleeve 7 moves to the right against the wall and the combined drill bit contacts the wall drilling position for drilling. Among them, the guide baffle 20 has multiple through holes on its plate surface corresponding to the positions of the middle drill bit 11 and the edge drill bit 13. When the middle drill bit 11 and the edge drill bit 13 pass through the corresponding through holes for drilling, the guide baffle 20 plays the role of blocking dust, so that the dust is collected in the dust collection sleeve 7 and located on the left side of the guide baffle 20. In the above structure, by setting a dust collection and noise reduction device on the electric drill body 1, the wall drilling position and the combined drill bit are covered in the dust collection sleeve 7, and the dust pollution effect is achieved. Furthermore, by setting a sound insulation and noise reduction pad on the outer wall of the dust collection sleeve 7, the noise pollution effect is reduced.

[0028] In the above structure, when the left end of the combined drill bit is in the drilling position, the left end of the dust collection sleeve 7 rests against the wall. As the drilling depth increases, the dust collection sleeve 7 slides to the right along the length of the guide rail 5. During this process, the left end of the dust collection sleeve 7 remains in contact with the wall, and the drilled debris and dust are collected inside the dust collection sleeve 7 until the required drilling depth is reached. The dust collection sleeve 7 can then be removed from the fixing sleeve 14, and the collected impurities and dust can be poured out.

[0029] The electric drill body 1 is a handheld structure. The handle at the bottom of the electric drill body 1 is fitted with a rubber vibration damping pad 2 to reduce hand vibration during mechanical operation, prevent slippage, and improve safety and reliability. The rear end of the electric drill body 1 is equipped with a balance grip 3, which works with the bottom handle to provide a dual-hold function.

[0030] This technical solution features a simple structure, precise positioning, neat edges, reduced pollution, good forming effect, high quality, no need for secondary repairs, high drilling efficiency, and is easy to promote and apply.
