Technical Field
[0001] The utility model relates to the technical field of drilling holes in a drill sleeve, in particular to a drilling dust suction device. Background Art
[0002] Drilling is the process of drilling holes in solid materials with a drill. This describes drilling in exploration work, the tools needed for drilling, and some emergency measures. It usually refers to drilling through hard objects with a sharp rotating tool. For example: drilling holes in a board, drilling holes in a metal plate in several places, drilling holes with a rock drill (in solid materials), drilling holes in granite. It also refers to drilling a row of small holes or patterns (usually with a machine) for decoration, identification, or easy separation, like canoes, and sometimes drilling boat-shaped gems as pendants.
[0003] When using an electric drill to drill holes in wooden boards and other locations where holes need to be drilled, some debris or dust will be generated in different working scenarios, which will splash as the drill head rotates, polluting the surrounding environment and possibly being inhaled into the airways of the workers, as well as threatening the safety of the workers with the splashed debris. At the same time, the exposed drill head of the electric drill also has certain safety hazards, thus posing a threat to the safety of the drilling operation. Based on this, we propose a drilling dust suction device. Utility Model Content
[0004] The purpose of the utility model is to provide a punching dust suction device to solve the problems raised in the above background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a perforated dust suction device comprises a protective shell, a protective sleeve is fixedly installed on one end of the protective shell, a plurality of arcuate strips are fixedly installed on the outer side of the protective sleeve, a positioning strip is hinged on one end of the arcuate strip, four folding plates are fixedly installed on the other end of the protective shell, threaded strips are arranged on the inner sides of the other ends of the four folding plates, positioning grooves are arranged on the outer sides of the positioning grooves, clamps are sleeved on the outer sides of the clamps, a collar is slidably installed on the outer sides of the clamps, a plurality of positioning holes are arranged inside the clamps, a fastening bolt is threadedly connected to the inner sides of the collars, and the folding plates are fixedly installed on the other ends of the four folding plates. A reinforcement ring is fixedly installed on the outer side of one end of the plate, and a reinforcement column is fixedly installed on the outer side of the reinforcement ring. A drill sleeve is movably inserted into the interior of the protective shell, and a turbine blade is movably sleeved on the outer side of the drill sleeve. A fixing ring is fixedly installed on the top of the inner cavity of the protective shell, and a T-ring is slidably installed inside the fixing ring. A number of bearing balls are movably installed on the opposite sides of the T-ring and the fixing ring at both ends, and a rubber ring seat is fixedly installed on the bottom end of the T-ring, and a ring plate is fixedly installed on the bottom end of the rubber ring seat. The fixing ring and the T-ring are sleeved on the outer side of the drill sleeve, and the ring plate is located on the top of the turbine blade. A guide channel is connected to one side of the protective shell.
[0006] Preferably, the arc strips are evenly distributed on the outside of the protective cover in a circumferential manner, one end of the positioning strip away from the arc strip is hinged to the outside of the protective shell, and the protective cover is made of a flexibly deformable material.
[0007] Preferably, the positioning holes are evenly distributed in a circumference inside the clamp, and the specification size of one end of the fastening bolt is matched with the specification size of the positioning holes.
[0008] Preferably, one end of the reinforcement column away from the folding plate is fixedly mounted on the outside of the protective shell, and the folding plate is an elastically deformable plastic structure.
[0009] Preferably, a hole larger than the drill sleeve is opened at one end of the protective shell, and the specification size of the inner side of the turbine blade is matched with the specification size of the outer side of the drill sleeve.
[0010] Preferably, the bearing balls are evenly distributed on the inner side of the fixing ring and the T-ring in a circumferential manner, and arc grooves matching the bearing balls are provided at corresponding positions of the fixing ring, the T-ring and the bearing balls, and lubricating oil is placed inside the arc grooves.
[0011] Compared with the prior art, the beneficial effect of the utility model is as follows: when the device is in use, the user first sleeves the folding plate on the fixed sleeve of the drill sleeve, and then stretches the clamp and the ring to make the clamp sleeve on the outside of the folding plate to make the folding plate fit tightly to the outside of the drill sleeve, and then tightens it by tightening the bolts to fix the folding plate and the protective shell in this position, and then connects the guide channel to the airflow guide pipe and connects it to the dust and debris collection position. Before this, the drill sleeve is installed in the fixed position of the drill sleeve and then the folding plate is installed. After fixing, the drill sleeve is used to drill holes. At this time, dust and debris splashed by the operation generate airflow when the turbine blades rotate with the drill sleeve, and the dust and debris are introduced into the interior of the guide channel, thereby achieving a protective effect. When the arc strip and the protective sleeve are used, the protective sleeve is deformed due to collision with an object, and expands outward under the limit of the arc strip, thereby avoiding the curling and locking effect with the drill sleeve when deforming inward, thereby further improving safety.
[0012] By providing the ring plate and rubber ring seat, if the operator penetrates an object during operation, the turbine blade collides with the object and moves up. At this time, the turbine blade contacts the ring plate and applies a rotational torque to the ring plate. The collision between the ring plate and the turbine blade causes the rubber ring seat to deform and initially buffer, and the rotational torque is transmitted to the T-ring through the rubber ring seat. Through the rotation buffer between the T-ring and the bearing ball and the fixed ring, the overall structure is driven to avoid direct contact between the turbine blade and the inner wall of the protective shell in an accident, thereby increasing protection, reducing damage caused by rigid collision between the protective shell and the turbine blade, further increasing service life, and having a good practical effect.

A reinforcement ring 10 is fixedly installed, and a reinforcement column 11 is fixedly installed on the outside of the reinforcement ring 10. A drill bit 4 is movably inserted into the inside of the protective shell 1, and a turbine blade 5 is movably sleeved on the outside of the drill bit 4. A fixing ring 17 is fixedly installed on the top of the inner cavity of the protective shell 1, and a T-ring 18 is slidably installed inside the fixing ring 17. A number of bearing balls 19 are movably installed on the opposite sides of the T-ring 18 and the fixing ring 17 at both ends. A rubber ring seat 20 is fixedly installed on the bottom end of the T-ring 18, and a ring plate 21 is fixedly installed on the bottom end of the rubber ring seat 20. The fixing ring 17 and the T-ring 18 are sleeved on the outside of the drill bit 4, and the ring plate 21 is located on the top of the turbine blade 5. One side of the protective shell 1 is connected with a guide channel 2.
[0021] The working principle of the above technical solution: when in use, the user first sleeves the folding plate 8 on the fixed sleeve of the drill sleeve, and then stretches the clamp 13 and the ring 15 to make the clamp 13 sleeve on the outside of the folding plate 8 to make the folding plate 8 fit tightly to the outside of the drill sleeve, and then tightens it by tightening the bolts 16 to fix the folding plate 8 and the protective shell 1 in this position, and then connects the guide channel 2 to the airflow guide pipe and connects it to the dust and debris collection position. Before this, install the drill bit 4 in the fixed position of the drill sleeve and then install the folding plate 8. After fixing, use the drill bit 4 to drill holes. At this time, the dust and debris splashed by the operation will generate airflow when the turbine blades 5 rotate with the drill bit 4, and the dust and debris will be introduced into the interior of the guide channel 2, thereby achieving the protective effect.
[0022] In another embodiment, Figure 1-Figure 4 As shown, the arc strips 6 are evenly distributed on the outside of the protective cover 3 in a circumferential manner, and one end of the positioning strip 7 away from the arc strip 6 is hinged to the outside of the protective shell 1. The protective cover 3 is made of a flexibly deformable material.
[0023] When the arc strip 6 and the protective sleeve 3 are in use, the protective sleeve 3 is deformed due to collision with an object and expands outward under the limitation of the arc strip 6, avoiding the curling and locking effect with the drill bit 4 when deforming inward, thereby further improving safety.
[0024] In another embodiment, Figure 1 and Figure 4As shown, the positioning holes 14 are evenly distributed in a circumference inside the clamp 13 , and the specification size of one end of the fastening bolt 16 is matched with the specification size of the positioning holes 14 .
[0025] This arrangement facilitates adjustment when installed outside a larger drill bit sleeve, thereby stabilizing the overall structure and increasing adaptability.
[0026] In another embodiment, Figure 1-Figure 4 As shown, one end of the reinforcement column 11 away from the folding plate 8 is fixedly installed on the outer side of the protective shell 1, and the folding plate 8 is an elastically deformable plastic structure.
[0027] The folding plate 8 can expand outward to adapt to drill bit sleeves of different sizes, and the thread setting of the threaded strip 9 increases the friction force, and the threaded installation sleeve with the set thread can be threadedly connected through the threaded strip 9, further increasing the firmness of the installation.
[0028] In another embodiment, Figure 1-Figure 3 As shown, a hole larger than the drill bit 4 is opened at one end of the protective shell 1, and the specification size of the inner side of the turbine blade 5 is matched with the specification size of the outer side of the drill bit 4.
[0029] The drill bit 4 passes through the protective shell 1 through the hole for easy installation. The turbine blade 5 can be sleeved on the outside of the protective shell 1, and turbine blades 5 of different sizes can be produced according to different drill bits 4. The split design is convenient for replacement according to the size of the drill hole, which improves the overall practicality, makes the product specifications more numerous, and has a good use effect.
[0030] In another embodiment, Figure 3 and Figure 5 As shown, the bearing balls 19 are evenly distributed on the inner sides of the fixing ring 17 and the T-ring 18 in a circumferential manner, and arc grooves matching the bearing balls 19 are provided at corresponding positions of the fixing ring 17 and the T-ring 18 and the bearing balls 19, and lubricating oil is placed inside the arc grooves.
[0031] By means of the provided ring plate 21 and the rubber ring seat 20, if the operator penetrates an object during operation, the turbine blade 5 collides with the object and moves upward, the turbine blade 5 contacts the ring plate 21 at this time, and applies a rotational torque to the ring plate 21. The collision between the ring plate 21 and the turbine blade 5 causes the rubber ring seat 20 to deform and initially buffer, and the rotational torque is transmitted to the T-ring 18 through the rubber ring seat 20. Under the rotation buffer between the T-ring 18 and the bearing ball 19 and the fixing ring 17, the overall structure is driven, thereby avoiding direct contact between the turbine blade 5 and the inner wall of the protective shell 1 in an accident, thereby increasing protection, reducing damage caused by rigid collision between the protective shell 1 and the turbine blade 5, further increasing the service life, and having a good practical effect.
