Description

Technical Field

[0001] This utility model relates to the field of drill bit machinery technology, and in particular to an impact drill bit. Background Technology

[0002] A drill bit is a tool used to drill holes in various materials. Drill bits are usually made of hard materials, such as high-speed steel and cemented carbide, to ensure that they can withstand the friction and pressure during the drilling process. Drill bits come in various types and sizes to meet different drilling needs. In the construction and decoration industry, drill bits are often used to drill holes in walls, floors and ceilings to install pipes, cables and fixtures.

[0003] Impact drill bits typically come in two modes: flat drilling and impact drilling. Flat drilling is suitable for materials such as wood and metal, while impact drilling is suitable for hard materials such as concrete and brick. During drilling, the combination of these two movements is used to break and cut the material to form a hole.

[0004] When using existing impact drills, operators with insufficient experience and skills may make mistakes in judgment, which will affect the drilling depth. They may not be able to drill to the standard depth accurately in one go, resulting in inaccurate hole depth and position, affecting subsequent construction. They may also need to measure the hole depth multiple times and drill multiple times, which can easily result in holes that are too long or too short. Furthermore, multiple drilling may lead to accidental loss of control of the tool, causing injury from flying debris. Utility Model Content

[0005] In view of the problem that the aforementioned impact drill bit cannot accurately drill to the standard depth in one go, resulting in inaccurate hole depth and position, this utility model is proposed.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] An impact drill bit includes a drill bit body, the drill bit body being composed of a working part and a shank, the working part having multiple rows of positioning holes horizontally arranged around its circumference;

[0008] A positioning mechanism, fitted onto a working part, includes a positioning frame located at the outer end of the working part. A sliding disk is rotatably disposed within the positioning frame. The sliding disk has multiple sliding grooves. A first sliding rod is slidably disposed within each sliding groove. A positioning rod is provided at one end of the first sliding rod. Both ends of the positioning rod penetrate the positioning frame. A sliding component is provided at one end of the sliding disk. A dustproof component is provided at one end of the positioning frame.

[0009] In a preferred embodiment of the impact drill bit of this utility model, the sliding assembly includes a connecting rod, which is fixedly disposed at one end of the sliding disk, and the connecting rod passes through the positioning frame and is connected to the sliding plate.

[0010] In a preferred embodiment of the impact drill bit of this utility model, a second sliding rod is provided at one end of the connecting rod, a fixed plate is provided inside the positioning frame, and the second sliding rod is slidably disposed inside the fixed plate. A spring is sleeved on the second sliding rod, and the two ends of the spring are respectively fixedly disposed on the fixed plate and one end of the connecting rod.

[0011] In a preferred embodiment of the impact drill bit of this utility model, the outer end of the sliding plate is provided with anti-slip teeth, and the sliding plate and the anti-slip teeth are integrally formed.

[0012] In a preferred embodiment of the impact drill bit of this utility model, the dustproof component includes a dustproof shell, which is disposed at one end of the positioning frame. The dustproof shell is threadedly connected to a dustproof cover, and a telescopic tube is disposed inside the dustproof shell. One end of the telescopic tube is connected to an adsorption element.

[0013] In a preferred embodiment of the impact drill bit of this utility model, the adsorption component includes an adsorption seat, which is disposed at one end of a telescopic tube. A plurality of helical gear sleeves are disposed at one end of the adsorption seat, and a helical gear disk is externally meshed with the plurality of helical gear sleeves. A limit thread rod is rotatably disposed on the internal thread of the helical gear sleeve. A connecting block is disposed at one end of the limit thread rod, and an adsorption disk is disposed at one end of the connecting block.

[0014] The beneficial effects of this utility model are:

[0015] 1. The positioning mechanism is designed to precisely position the drill bit body by rotating the sliding plate and sliding rod to make the positioning rod abut against the positioning holes at different positions, according to the required drilling depth. This ensures that the depth of each hole is consistent, improving the accuracy and stability of drilling. Through the cooperation of springs, connecting rods, and sliding plates, the positioning can be automatically completed under the elastic action of the spring after the sliding plate is released, improving work efficiency.

[0016] 2. The adsorption plate and adjustable helical gear structure can more firmly align with the perforated position for adsorption, improving the effectiveness and adaptability of the dustproof component. At the same time, it concentrates the generated dust inside the telescopic tube, preventing it from soiling other areas, maintaining a clean working environment, and reducing the impact of dust on the surrounding environment and worker health.

[0025] 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.

[0026] Example 1

[0027] Reference Figure 1-5This is the first embodiment of the present invention, which provides an impact drill bit, including a drill bit body 1. The drill bit body 1 is composed of a working part 11 and a shank 12. The working part 11 is provided with multiple rows of positioning holes 2 arranged horizontally around its circumference. A positioning mechanism 3 is sleeved on the working part 11 and includes a positioning frame 34 disposed at the outer end of the working part 11. A sliding disk 32 is rotatably disposed within the positioning frame 34. Multiple sliding grooves are opened on the sliding disk 32. A first sliding rod 33 is slidably disposed within the sliding groove. A positioning rod 31 is fixedly disposed at one end of the first sliding rod 33. Both ends of the positioning rod 31 slide through the positioning frame 34. Under normal conditions, the opposite ends of the multiple positioning rods 31 are in an abutting state. The multiple first sliding rods 33 are rotated within the sliding groove by rotating the sliding disk 32. The first sliding rods 33 drive the positioning rods 31 to slide within the positioning frame 34. When the positioning rods 31 abut against the positioning holes 2, the drill bit body 1 is positioned.

[0028] Furthermore, a sliding component 4 is provided at one end of the sliding disk 32. The sliding component 4 includes a connecting rod 41, which is fixedly disposed at one end of the sliding disk 32. A second sliding rod 43 is provided at one end of the connecting rod 41. A fixing plate 42 is provided inside the positioning frame 34, and the second sliding rod 43 is slidably disposed within the fixing plate 42. A spring 45 is sleeved on the second sliding rod 43. The two ends of the spring 45 are respectively fixedly disposed at one end of the fixing plate 42 and the connecting rod 41. The connecting rod 41 passes through the positioning frame 34 and is connected to the sliding plate 44. A slot for the connecting rod 41 to slide is provided on the positioning frame 34. An anti-slip tooth 46 is provided at the outer end of the sliding plate 44. The anti-slip tooth 46 can enhance the friction with the hand while sliding the sliding plate 44, preventing slippage when sliding the sliding plate 44. Slippage occurs because the sliding plate 44 and the anti-slip teeth 46 are integrally formed. As mentioned above, the sliding plate 44 drives the connecting rod 41 to slide in the slot on the positioning frame 34. The sliding of the connecting rod 41 drives the sliding disk 32 to rotate. The sliding disk 32 drives the positioning rod 31 to expand outward within the positioning frame 34 through the first sliding rod 33. Then, according to the drilling depth requirement, the positioning mechanism 3 is fitted onto the corresponding positioning hole 2 outside the working part 11. Then, the sliding plate 44 is released. Under the elasticity of the spring 45, the second sliding rod 43 drives the connecting rod 41 to slide within the fixed plate 42. The connecting rod 41 drives the sliding disk 32 to rotate in the opposite direction. The sliding disk 32 drives the positioning rod 31 to slide within the positioning frame 34 through the first sliding rod 33. When the positioning rod 31 and the positioning hole 2 come into contact, the positioning is completed.

[0029] Example 2

[0030] Reference Figure 4-5 This is the second embodiment of the present invention, which differs from the first embodiment in that:

[0031] A dustproof component 5 is provided on one side of the positioning frame 34. The dustproof component 5 includes a dustproof shell 51, which is located at one end of the positioning frame 34. A dustproof cover 52 is threadedly connected to the dustproof shell 51. A telescopic tube 53 is provided inside the dustproof shell 51. An adsorption component 54 is connected to one end of the telescopic tube 53. The adsorption component 54 includes an adsorption seat 544, which is located at one end of the telescopic tube 53. Multiple helical gear sleeves 545 are provided at one end of the adsorption seat 544. A helical gear disk 546 is externally meshed with the multiple helical gear sleeves 545. A limit thread rod 543 is provided for the internal rotation of the helical gear sleeves 545. A connecting block 542 is provided at one end of the limit thread rod 543. An adsorption component is provided at one end of the connecting block 542. Following the above steps, after completing the above work, open the dust cover 52 on the dustproof shell 51, extend the telescopic tube 53, and then align the adsorption plate 541 with the position to be drilled. Then rotate the helical gear plate 546, which drives the multiple meshing helical gear sleeves 545 to rotate. The rotation of the helical gear sleeves 545 drives the threaded limit thread rod 543 to rotate. The limit thread rod 543 drives the adsorption plate 541 to adsorb the drilling position through the connecting block 542. Then, when the drill bit body 1 drills, the dust generated is concentrated in the telescopic tube 53 to avoid soiling other positions.

[0032] The remaining structure is the same as that in Example 1.

[0033] The specific operating principle of this utility model is as follows:

[0034] When the drill bit body 1 needs to drill, the positioning mechanism 3 and the dustproof component 5 are threaded together and fitted onto the drill bit body 1. Then, the sliding plate 44 is rotated, and the sliding plate 44 drives the connecting rod 41 to slide on the positioning frame 34. Then, the connecting rod 41 drives the sliding disk 32 to rotate inside the positioning frame 34. Then, the sliding disk 32 drives the positioning rod 31 to expand outward within the positioning frame 34 through the first sliding rod 33. Then, according to the drilling depth requirement, the positioning mechanism 3 is fitted onto the corresponding positioning hole 2 outside the working part 11. Then, the sliding plate 44 is released. Under the elasticity of the spring 45, the second sliding rod 43 drives the connecting rod 41 to slide inside the fixed plate 42. The connecting rod 41 drives the sliding disk 32 to rotate in the opposite direction. The sliding disk 32 drives the positioning rod 31 to slide inside the positioning frame 34 through the first sliding rod 33. When the positioning rod 31 and the positioning hole 2 abut, the positioning is completed.

[0035] Furthermore, open the dust cover 52 on the dust cover 51, extend the telescopic tube 53, align the suction plate 541 with the position to be drilled, and then rotate the helical gear disk 546. The helical gear disk 546 drives the multiple meshing helical gear sleeves 545 to rotate. Then, the rotation of the helical gear sleeves 545 drives the threaded limit thread rod 543 to rotate. Then, the limit thread rod 543 drives the suction plate 541 to adsorb the drilling position through the connecting block 542. Then, when the drill bit body 1 drills, the dust generated is concentrated in the telescopic tube 53 to avoid soiling other positions.
