Description

Technical Field

[0001] This utility model belongs to the technical field of building installation, and specifically relates to a drilling device for building installation. Background Technology

[0002] The construction of a building project generally involves three stages: surveying, design, and construction. During the construction stage, drilling guns are often used to drill holes in walls or other surfaces to facilitate the passage of cables or other wires. Drilling can also be used to install screws in the holes to facilitate the installation of building materials.

[0003] Drilling guns produce a lot of debris when drilling. The debris flies around under the force of the drill bit's rotation. The debris and dust pollute the operating environment, affecting visibility and making drilling difficult. In addition, the dust can enter the operator's lungs and affect human health. Utility Model Content

[0004] The purpose of this utility model is to provide a drilling device for building installation, which aims to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A drilling device for building installation includes a dust suppression component and a drilling gun body. A mounting frame is fixedly connected to the outside of the drilling gun body. A water storage bottle is fixedly connected inside the mounting frame. A one-way air injection pipe and a one-way water injection pipe are fixedly connected to the top of the water storage bottle. A water delivery pipe is fixedly connected to the bottom of the water storage bottle. A shielding plate is provided inside the water storage bottle, and an adjustment component is provided inside the shielding plate. The adjustment component includes a fixing block, which is fixedly connected to the left side of the mounting frame. A rotating shaft is rotatably connected inside the fixing block, and a nozzle is fixedly connected to the middle of the rotating shaft.

[0007] In a preferred embodiment of this utility model, the adjustment component includes an adjustment shaft, which is fixedly connected inside the baffle plate. A sealing ring is provided between the adjustment shaft and the water storage bottle. A positioning chuck is fixedly connected to the outside of the adjustment shaft. A protrusion is fixedly connected to the right side of the mounting bracket. A positioning block is rotatably connected inside the protrusion. A tension spring is fixedly connected to the left side of the positioning block.

[0008] In a preferred embodiment of this utility model, the end of the tension spring away from the positioning block is fixedly connected to the right side of the mounting bracket, and the positioning chuck and the positioning block are provided with six slots at corresponding positions, and the positioning block is engaged inside the slots.

[0009] In a preferred embodiment of this utility model, the positioning chuck is located on the right side of the mounting frame, and the adjusting shaft is rotatably connected between the mounting frame and the inside of the water storage bottle.

[0010] As a preferred embodiment of this utility model, two damping pads are fixedly connected between the rotating shaft and the fixing block, a flexible hose is fixedly connected to the bottom of the nozzle, and a plastic clip is fixedly connected to the left side of the mounting bracket.

[0011] In a preferred embodiment of this utility model, the nozzle is snapped into the inside of the plastic clip, the end of the hose away from the nozzle is connected to the end of the water supply pipe away from the water storage bottle, and an adjustment handle is fixedly connected to the back of the rotating shaft.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. Through the dust suppression components, the shielding plate deflects around the adjustment shaft, creating a gap between itself and the inner wall of the water storage bottle. At this time, the pressure inside the water storage bottle continuously forces out the water. The water flows through the gap into the water supply pipe, then into the water supply pipe and hose, and finally is sprayed out through the nozzle. The water molecules form a thin wet layer on the surface of the material to be drilled, acting as an "adhesive". During drilling, the nozzle can also continuously spray water mist for continuous dust suppression, thus forming a dual effect of "pre-wetting + real-time dust suppression".

[0014] 2. Through the set adjustment components, the rotating shaft drives the nozzle to rotate, thereby rotating the nozzle to align with the drill hole. The operator can quickly, intuitively and accurately adjust the nozzle to the optimal spray angle. The operator can adjust the nozzle's elevation angle in real time to ensure that the water mist can accurately cover the drill hole point and maximize the dust suppression effect.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] Example 1

[0024] Reference Figures 1-4 This is the first embodiment of the present utility model. This embodiment provides a drilling device for building installation, including a dust suppression component, including a drilling gun body 10, a mounting frame 11 fixedly connected to the outside of the drilling gun body 10, a water storage bottle 12 fixedly connected inside the mounting frame 11, a one-way air injection pipe 13 fixedly connected to the top of the water storage bottle 12, a one-way water injection pipe 14 fixedly connected to the top of the water storage bottle 12, a water supply pipe 15 fixedly connected to the bottom of the water storage bottle 12, a shielding plate 16 provided inside the water storage bottle 12, and an adjustment component 17 provided inside the shielding plate 16.

[0025] Both the one-way air injection pipe 13 and the one-way water injection pipe 14 are equipped with one-way valves, which allow water and gas to be injected into the water storage bottle 12, thereby keeping the inside of the water storage bottle 12 sealed and facilitating the spraying of water through the nozzle 23 under air pressure.

[0026] Furthermore, the adjustment assembly 17 includes an adjustment shaft 171, which is fixedly connected inside the baffle plate 16. A sealing ring 172 is provided between the adjustment shaft 171 and the water storage bottle 12. A positioning chuck 173 is fixedly connected to the outside of the adjustment shaft 171. A protrusion 174 is fixedly connected to the right side of the mounting bracket 11. A positioning block 175 is rotatably connected inside the protrusion 174. A tension spring 176 is fixedly connected to the left side of the positioning block 175.

[0027] The positioning chuck 173 and the positioning block 175 work together, with the positioning block 175 engaging with different slots. The gap between the sealing ring 172 and the water storage bottle 12 is different, so that when the air pressure inside the water storage bottle 12 decreases, the gap is increased, thereby ensuring sufficient water spray and better dust suppression.

[0028] Preferably, the end of the tension spring 176 away from the positioning block 175 is fixedly connected to the right side of the mounting bracket 11. The positioning chuck 173 and the positioning block 175 are provided with six slots at corresponding positions, and the positioning block 175 is engaged in the slots. The positioning chuck 173 is located on the right side of the mounting bracket 11, and the adjusting shaft 171 is rotatably connected to the inside of the mounting bracket 11 and the water storage bottle 12.

[0029] It should be noted that the adjusting shaft 171 is rotatably connected to the mounting bracket 11 and the water storage bottle 12, which drives the baffle plate 16 to deflect around the adjusting shaft 171, so that the baffle plate 16 and the inner wall of the water storage bottle 12 are separated, thereby allowing the internal water to flow out for spraying.

[0030] Before use, the drill gun body 10 is pre-filled with water to nine-tenths full through the one-way water injection pipe 14 into the water storage bottle 12. Then, air is pumped into the water storage bottle 12 through the one-way air injection pipe 13 via the air inflation device. Due to the internal sealing of the water storage bottle 12 under the action of the baffle plate 16, pressure is formed inside the water storage bottle 12. When dust suppression is required, the positioning block 175 is pushed closer to the mounting bracket 11, which compresses the tension spring 176. At this time, the end of the positioning block 175 away from the tension spring 176 disengages from the positioning clip. Inside the slot of disc 173, the locking of the positioning disc 173 is released. The right handle of the adjusting shaft 171 is then rotated, causing the adjusting shaft 171 to rotate the baffle 16 around the adjusting shaft 171, creating a gap between the baffle 16 and the inner wall of the water bottle 12. The pressure inside the water bottle 12 continuously forces water out, and the water flows through the gap into the water pipe 15, then into the water pipe 15 and the hose 24, finally spraying out through the nozzle 23. The positioning block 175 is no longer pressed, and the tension is increased. Spring 176 drives positioning block 175 to engage with another slot, fixing the position of baffle 16 and allowing continuous water flow. At this time, the drill gun body 10 is not in use. The spray from nozzle 23 humidifies the drilling area, and water molecules form a thin, moist layer on the surface of the material to be drilled, acting as an "adhesive." When the drill gun body 10 starts working, the generated debris is no longer dry, flying dust, but rather heavier, moist particle clusters adhered to by water, thus preventing... First, dust is avoided. Second, before drilling, the air in the operating area is kept clean and free of dust interference, which helps improve the accuracy of drilling and avoids drilling off-center due to blurred vision during multi-hole drilling operations. Then, the drill gun body 10 is held and the button is pressed to rotate the drill and drill. At this time, the nozzle 23 continuously sprays water mist for continuous dust suppression, thus forming a dual effect of "pre-humidification + real-time dust suppression", which makes the dust suppression effect better, reduces the risk of operators inhaling dust, and provides a higher level of protection for health.

[0031] Example 2

[0032] Reference Figure 2 , Figure 5 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides an adjustment component, including a fixing block 20. The fixing block 20 is fixedly connected to the left side of the mounting bracket 11. A rotating shaft 21 is rotatably connected inside the fixing block 20. A nozzle 23 is fixedly connected to the middle of the rotating shaft 21. Two damping pads 22 are fixedly connected between the rotating shaft 21 and the fixing block 20. A hose 24 is fixedly connected to the bottom of the nozzle 23. A plastic clip 25 is fixedly connected to the left side of the mounting bracket 11. The nozzle 23 is clipped into the inside of the plastic clip 25. The end of the hose 24 away from the nozzle 23 is connected to the end of the water supply pipe 15 away from the water storage bottle 12. An adjustment handle is fixedly connected to the back of the rotating shaft 21.

[0033] When not in use, the nozzle 23 is in a vertical position, locked inside the plastic clip 25. This prevents the nozzle 23 from wobbling during the handling of the drill gun body 10, thus avoiding impact with the drill bit. This ensures that the core components (drill bit and nozzle 23) are effectively protected when not in use, guaranteeing the equipment is always in good working order. When using the drill gun body 10, the adjusting handle of the shaft 21 is pre-rotated, causing the shaft 21 to rotate the nozzle 23, aligning it with the drill hole. The operator can quickly, intuitively, and precisely adjust the nozzle 23 to the optimal spray angle, and can adjust the nozzle 23's elevation angle in real time. To ensure that the water mist accurately covers the drilling point and maximizes the dust suppression effect, a damping pad 22 is installed between the rotating shaft 21 and the fixed block 20. The damping pad 22 provides continuous resistance through friction, achieving "stepless positioning". The operator can adjust the nozzle 23 to any angle and keep it stable, achieving a precise "point-and-shoot" effect. The adjustability and adaptability of the nozzle 23 are stronger. Different drilling positions (top, wall, ground) require different nozzle 23 angles. The adjustable design allows the equipment to easily adapt to various working scenarios. Even during the drilling process, if the water mist coverage is not ideal, the operator can easily make fine adjustments without interrupting the operation, which greatly enhances the professional image of the product and the user's trust in the product quality.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
