Technical Field

[0001] This utility model relates to the field of impact drilling equipment technology, and in particular to a dust prevention device for impact drilling used in construction engineering services. Background Technology

[0002] Impact drills for construction services are electric tools that primarily use rotary cutting while also incorporating impact capabilities. They can drill holes in concrete and brick walls for installing pipes and other facilities. Available in handheld and cabinet-style models, they can be switched between ordinary drilling and impact drilling functions through adjustment, offering advantages such as ease of operation and high efficiency.

[0003] Traditional impact drills use dust covers, dust bags, and vacuum cleaner interfaces for dust prevention during use. However, dust leakage is common during use, resulting in poor dust prevention and unstable connections between the dust cover and the drill, which can easily detach.

[0004] Therefore, those skilled in the art have provided a dust prevention device for impact drills used in construction engineering services to solve the problems mentioned in the background art. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Reference Figure 1 - Figure 5 An embodiment of this utility model is provided: a dustproof device for impact drills used in construction engineering services, including an installation pipe 1 and two rebound components 3. A folded pipe 5 is fixedly installed at the upper end of the installation pipe 1, and a compression ring 6 is fixedly installed at the upper end of the folded pipe 5. A receiving groove 8 is opened in the middle of the lower end face of the installation pipe 1, and a clamping component 2 is fixedly installed inside the receiving groove 8. A first threaded hole 4 is opened at the lower part of the middle of both sides of the installation pipe 1. The upper end face of the mounting tube 1 has a through hole 7 in the middle, and the folded tube 5 is made of polyurethane material.

[0018] Specifically, the folded tube 5, made of polyurethane material, is located at the upper end of the mounting tube 1, thus improving its service life. A rectangular receiving groove 8 at the lower end of the mounting tube 1 facilitates the accommodating of the clamping assembly 2, which in turn allows for the clamping and fixing of different types of impact drills, enhancing clamping stability. First threaded holes 4, located on the lower middle of both sides of the mounting tube 1, work with the clamping assembly 2 to clamp and fix the impact drill. A through hole 7, located in the middle of the upper surface of the mounting tube 1, allows the drill bit of the impact drill to pass through.

[0019] Reference Figure 1 , Figure 2 , Figure 3 , Figure 5 The rebound assembly 3 includes a connecting block 301, a fixing box 303 and a sliding hole 304. A rebound rod 302 is fixedly installed at the lower end of the connecting block 301. A sliding plate 308 is fixedly installed at the lower end of the rebound rod 302. A through hole 307 is opened in the middle of the lower end face of the rebound rod 302. A through rod 305 is fixedly installed in the middle of the bottom surface of the sliding hole 304. A second strong spring 306 is sleeved around the through rod 305. The sliding plate 308 is slidably disposed inside the sliding hole 304, the through rod 305 is disposed through the through hole 307, and the second strong spring 306 is fixed between the sliding plate 308 and the inner bottom surface of the sliding hole 304.

[0020] Specifically, the rebound rod 302, located at the lower end of the connecting block 301 in the rebound assembly 3, slides inside the sliding hole 304 in the fixed box 303 via the sliding plate 308 connected to the rebound rod 302. The through rod 305, located on the bottom surface of the sliding hole 304, passes through the through hole 307 in the rebound rod 302. The inner diameter of the through hole 307 is the same as the diameter of the through rod 305. A second strong spring 306, fixed to the sliding block and the bottom surface of the sliding hole 304, presses against the wall surface when the connecting block 301 and the compression ring 6 connected to the through rod 305 are pressed. The sliding block presses against the second strong spring 306 around the through rod 305, generating a rebound. This allows the compression ring 6 to continuously press against the working surface, preventing gaps that could lead to dust leakage and improving the dustproof effect during the use of the impact drill.

[0021] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 The clamping assembly 2 includes two threaded rods 202, two movable plates 203 and two through rods 205. A clamping plate 206 is fixedly provided in the middle of the opposite side of the two movable plates 203. A first strong spring 207 is sleeved in the middle of the two through rods 205. A second threaded hole 204 is opened in the middle of the opposite side of the two movable plates 203. Two first-strength springs 207 are fixed at the front and rear ends of the two movable plates 203 respectively. The front and rear ends of the two movable plates 203 are slidably arranged around the two through rods 205. The two clamping plates 206 are made of rubber. Torque blocks 201 are fixedly arranged on opposite sides of the two threaded rods 202.

[0022] Specifically, the clamping plate 206 on the opposite side of the movable plate 203 in the clamping assembly 2 is arc-shaped and made of rubber material. The high friction makes it less likely to slip when clamping the impact drill, thus improving stability. The second threaded holes 204 on both sides of the movable plate 203 are connected to the first threaded hole 4 by the threaded rod 202, which is also threaded to the second threaded hole 204. The clamping size of the clamping plate 206 can be freely adjusted to clamp and fix different models of impact drills. The movable plate 203 slides around the through rod 205. The first strong spring 207 around the through rod 205 is fixed between the movable plates 203, giving the movable plates 203 a rebound, further improving the clamping stability.

[0023] Working principle: When using the impact drill, the impact drill is placed inside the receiving groove 8 of the installation tube 1, so that the drill bit passes through the through hole 7. By twisting the torsion block 201 in the clamping assembly 2, the threaded rod 202 is driven to rotate inside the first threaded hole 4, and the threaded rod 202 is threadedly connected inside the second threaded hole 204 on the moving plate 203. This causes the moving plate 203 to move relative to the moving rod, and the impact drill is clamped and fixed by the clamping plate 206. The extrusion ring 6 connected to the folded tube 5 extrudes the working surface. As the drilling depth increases, the folded tube 5 is folded, and the spring-loaded assembly 3 connected to the extrusion ring 6 causes the folded tube 5 to rebound in the direction of force, making the extrusion ring 6 fit more tightly against the working surface, reducing dust leakage and improving the dustproof effect.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
