Technical Field
[0001] This utility model relates to the field of drilling tool technology, specifically to an adjustable oblique drilling device. Background Technology
[0002] In the fields of building construction and equipment installation, drilling is a fundamental operation widely used in structural reinforcement, equipment installation, wiring, and ventilation duct layout. Traditional drilling operations are mostly vertical or horizontal. However, when the construction environment is limited, the spatial structure is complex, or the functional requirements are special (such as installing pipelines, bolts, brackets, or guiding devices on the side walls, load-bearing beams, sloping structures, or floor edges of buildings), it is often necessary to drill at a certain angle to meet specific stress requirements or construction path design. Usually, such angled drilling not only requires precise alignment of the hole diameter and direction, but also must ensure that the integrity and load-bearing capacity of the original structure are not damaged during the drilling process.
[0003] In existing technologies, angled drilling typically relies on workers using handheld electric drills or simple supports. The drilling angle is mainly determined by visual estimation or temporary measuring tools. However, due to the randomness of manual operation and significant environmental influences, the drilling angle is often difficult to control accurately, leading to large deviations in the drilling direction and affecting the accuracy of subsequent structural installation. Furthermore, since sidewall drilling is usually performed vertically or at heights, the worker's posture is inconvenient. Uneven stress between the drill rod and the wall surface easily causes problems such as drill slippage, deviation, or hole wall breakage, resulting in surface peeling or loosening of internal materials, thus reducing the overall aesthetics and durability of the building. In addition, traditional drilling supports usually only have single-direction adjustment capabilities, failing to achieve precise angle fine-tuning. When drilling at multiple angles or repeatedly at different locations is required, operators often need to repeatedly reposition and calibrate, reducing construction efficiency, increasing operational errors, and failing to meet the diverse construction requirements in complex building environments.
[0004] Therefore, there is an urgent need to develop an adjustable sidewall drilling angle device with a reasonable structural design, convenient angle adjustment, accurate positioning, and safe operation, so as to achieve precise control and stable maintenance of the drilling angle, thereby improving the accuracy and reliability of oblique drilling of sidewalls in building construction, reducing damage to the wall, and improving the overall construction efficiency. Utility Model Content
[0005] To address the problems of existing drilling technologies, such as reliance on manual experience leading to low precision and poor repeatability, as well as uncontrollable drilling device angles, simplistic structures, and poor stability, this invention proposes an adjustable oblique drilling device. The technical solution of this invention is as follows: An adjustable oblique drilling device includes a guide tube, a telescopic adjustment component, and a protractor; The guide tube has a hollow structure; the guide tube is rotatably connected to the telescopic adjustment component to realize the tilt angle adjustment and position fixation of the guide tube; the protractor is placed on one side of the guide tube; the intersection of the central axis of the guide tube and the extension line of the 0 degree scale of the protractor is the drilling center point.
[0006] The oblique adjustable drilling device also includes a wall plate and a base plate. The wall plate is attached to the side wall surface, and the base plate is placed on the ground. Both the wall plate and the base plate are made of iron or plastic. The two ends of the protractor are fixedly connected to the wall plate and the base plate, respectively, and the two ends of the protractor are perpendicular to the wall plate and the base plate, respectively.
[0007] The telescopic adjustment component includes a vertical adjustment rod and an adjustment support base; the vertical adjustment rod is connected to the adjustment support base via a telescopic joint; the adjustment support base is connected to a slide rail mounted on the base plate to achieve angle adjustment of the guide tube; since the adjustment support base, the base plate, and the guide tube form a stable triangular structure, the adjustment support base can be fixed under the gravity of the guide tube after its lateral position is adjusted, eliminating the need for a lateral fixing component. The slide rail is common knowledge in the art, and its structure will not be described in detail.
[0008] The adjusting support is equipped with a locking mechanism; the locking mechanism achieves the fixed positioning of the vertical adjusting rod by radially pressing the vertical adjusting rod with bolts.
[0009] The guide tube is rotatably connected to the telescopic adjustment component via a rotating connecting seat. One end of the rotating connecting seat is sleeved with the guide tube to support and limit the radial position of the guide tube. The other end of the rotating connecting seat and the vertical adjustment rod are rotatably connected to the adjustment support seat via bolts. The guide tube rotates around the bolt axis and is fixed by tightening the bolt with a nut to fix the orientation of the guide tube.
[0010] The telescopic adjustment component shall have at least one set of structures.
[0011] Furthermore, two sets of telescopic adjustment components are provided, and the two sets of telescopic adjustment components are arranged in parallel.
[0012] The vertical adjusting rod is a steel pipe that can be replaced with different diameters, and the guide tube is a steel pipe.
[0013] The working process of the adjustable oblique drilling device is as follows: Adjust the lateral distance between the adjustable drilling device and the drilling position; specifically, move the adjusting support to the appropriate position via the slide rail; adjust the angle of the guide tube according to the angle requirements of the drilling position and the scale of the protractor; then adjust the extension length of the vertical adjusting rod and the rotation angle of the guide tube until the intersection of the central axis of the guide tube and the extension line of the 0-degree scale of the protractor coincides with the center of the drilling hole, and then lock the entire vertical adjusting rod through the locking mechanism; insert the electric drill rod into the guide tube to carry out drilling.
[0014] Compared with existing technologies, this utility model solves the problems of existing technologies, such as reliance on manual experience in drilling, low precision, poor repeatability, uncontrollable drilling device angle, simple structure, and poor stability. Specifically, the beneficial effects are as follows: 1. High-precision drilling angle control: The oblique adjustable drilling device provided by this utility model achieves high-precision adjustable control of the drilling angle through the coordinated operation of the guide tube, the telescopic adjustment component, and the protractor. Utilizing the vertical extension and lateral displacement function of the telescopic adjustment component, the position of the guide tube can be precisely fine-tuned in multiple dimensions, and the angle can be corrected in real time according to the protractor reading. This structural design ensures the consistency of the drilling angle, is fully applicable to repeated construction on site, significantly improves the accuracy and controllability of drilling operations, and effectively overcomes the shortcomings of existing technologies, such as reliance on manual judgment, poor angle control accuracy, and insufficient repeatability.
[0015] 2. High Stability: This invention introduces a rotating connection assembly between the guide tube and the telescopic adjustment component. The guide tube can rotate around the bolt axis via the rotating connection seat, and the bolt is tightened and fixed by a nut, thus fixing the orientation of the guide tube. This structural design achieves precise angle adjustment of the guide tube while ensuring its stability during the angle adjustment process, ensuring the continuous stability of the drill bit's entry angle. Simultaneously, this invention utilizes an adjusting support seat and locking structure to reliably fix the vertical adjustment rod, effectively avoiding problems such as drilling deviation and hole wall damage, thereby improving drilling accuracy and the lifespan of the device structure.
[0016] 3. Convenient Operation: The inclined adjustable drilling device provided by this utility model has a stable structure and is easy to operate. Quick adjustments can be made simply by reading a protractor, eliminating the need for additional angle measuring instruments or complex positioning devices. The adjustment process is intuitive and responsive, significantly reducing the operational difficulty and labor intensity for construction workers. Furthermore, the device is easy to install and disassemble quickly, and is applicable to drilling scenarios with various angles, walls, or panels, possessing high adaptability and on-site operational efficiency, meeting the needs of high-precision and high-efficiency construction.

[0019] Example 1. like Figure 1 As shown, an adjustable inclined drilling device includes a guide tube 3, a telescopic adjustment component, and a protractor 5. The guide tube 3 is a hollow structure through which a drill rod 7 of an electric drill can pass. The guide tube 3 is rotatably connected to the telescopic adjustment component to realize the adjustment of the tilt angle and the fixation of the position of the guide tube 3. The protractor 5 is placed on one side of the guide tube 3. The intersection of the central axis of the guide tube 3 and the extension line of the 0-degree scale line of the protractor 5 is the drilling center point 6.
[0020] In this embodiment, two sets of telescopic adjustment components are provided, and the two sets of telescopic adjustment components are arranged in parallel. Each telescopic adjustment component includes a vertical adjustment rod 4, an adjustment support 41, and a rotating connecting seat 32. The vertical adjustment rod 4 is connected to the telescopic joint of the adjustment support 41. The adjustment support 41 is connected to a slide rail mounted on the base plate 2 to achieve angle adjustment of the guide tube 3. Since the adjustment support 41, the base plate 2, and the guide tube 3 form a stable triangular structure, the adjustment support 41 can be fixed under the gravity of the guide tube 3 after its lateral adjustment, eliminating the need for lateral fixing components. The slide rail is common knowledge in the art, and its structure will not be described in detail.
[0021] The vertical adjusting rod 4 is a replaceable steel pipe of different diameters, and the guide tube 3 is a steel pipe. The adjusting support 41 is equipped with a locking mechanism 42; the locking mechanism 42 achieves the fixed positioning of the vertical adjusting rod 4 by radially pressing the bolts. The inclined adjustable drilling device also includes a wall plate 1 and a base plate 2 made of iron plate or high-strength plastic plate, respectively. The wall plate 1 is attached to the side wall surface, and the base plate 2 is placed on the ground. The two ends of the protractor 5 are fixedly connected to the wall plate 1 and the base plate 2, respectively, and the two ends of the protractor 5 are perpendicular to the wall plate 1 and the base plate 2, respectively. The guide tube 3 is rotatably connected to the telescopic adjustment component via a rotating connecting seat 32. One end of the rotating connecting seat 32 is sleeved with the guide tube 3 to support and limit the radial position of the guide tube 3. The other end of the rotating connecting seat 32 and the end of the vertical adjustment rod 4 away from the adjustment support seat 41 are rotatably connected by bolts. The guide tube 3 rotates around the bolt axis 31 as the rotation center and is fixed by tightening the bolt with a nut to achieve the orientation fixation of the guide tube 3.
[0022] like Figure 2 As shown, the working process of the inclined adjustable drilling device provided by this utility model is as follows: Adjust the lateral distance between the inclined adjustable drilling device and the position to be drilled; specifically, move the adjusting support 41 to the appropriate position via the slide rail; According to the required angle of the drilling position, adjust the angle of the guide tube 3 according to the scale of the protractor 5; then adjust the extension length of the vertical adjustment rod 4 and the rotation angle of the guide tube 3 until the intersection of the central axis of the guide tube 3 and the extension line of the 0 degree scale of the protractor 5 coincides with the center of the drilling. Then, lock the entire vertical adjustment rod 4 through the locking mechanism 42. Insert the drill rod 7 into the guide tube 3 to perform drilling.
[0023] In summary, the inclined adjustable drilling device provided by this utility model achieves high-precision adjustable control of the drilling angle through the coordinated cooperation between the guide tube 3, the telescopic adjustment component and the protractor 5, which significantly improves the accuracy and controllability of drilling operations. At the same time, this utility model uses the adjusting support 41 and the locking mechanism 42 to reliably fix the vertical adjustment rod 4, effectively avoiding problems such as drilling deviation and hole wall damage, and meeting the needs of high-precision and high-efficiency construction.
