Description

Technical Field

[0001] This utility model relates to the field of drilling tools, and more specifically, to a simple drilling tool. Background Technology

[0002] In the process of geological exploration, the main specialized mechanical equipment that drives the drilling tools to extract physical geological data such as rock cores, mineral cores, rock cuttings, liquid samples, and gaseous samples from the ground is called a drilling tool.

[0003] Traditional drilling tools typically require large equipment and highly skilled personnel to operate, making them costly and difficult to carry. However, sometimes simple drilling work is needed, such as in the field or for home DIY projects, where traditional drilling tools are unsuitable. For example, a rotary impact ultrasonic drill with a single piezoelectric ceramic stack and unidirectional drive, disclosed in CN112727355B, addresses the problems of existing rotary impact ultrasonic drills, such as the structural limitations of their piezoelectric transducers, which result in a smaller volume of the piezoelectric ceramic stack, affecting the drill's drive power; and the overall length and weight of the drill. The longitudinal-torsion conversion amplitude transformer includes an amplitude transformer body and a longitudinal-torsion coupling vibrator integrally mounted on the amplitude transformer body. The end of the amplitude transformer body away from the rear cover plate and the longitudinal-torsion coupling vibrator are both installed inside the housing, with the longitudinal-torsion coupling vibrator fixed to one end of the housing. The rotor is located inside the housing and rotatably mounted on the amplitude transformer body, with one end of the rotor abutting the longitudinal-torsion coupling vibrator. At the end of the coupled oscillator, the drill bit is fixedly connected to the rotor head to tail, and a free mass block is set between one end of the amplitude rod body and one end of the rotor.

[0004] While this design improves the drilling speed and addresses some of the shortcomings of traditional drills, it is costly and requires a high level of technical and professional expertise from the user, making it unsuitable for some simple drilling tasks. To overcome the shortcomings of traditional drills, we propose a simplified drill that can be widely used in home DIY, field exploration, building repair, and other fields. Utility Model Content

[0021] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Please see Figures 1-3 This utility model provides a technical solution:

[0023] A simple drilling tool includes a base 1, a bracket 2 mounted on the top surface of the base 1, and two support columns 21 mounted on the upper surface of the base 1. Fixing blocks 22 are fixedly sleeved at the bottom and near the top of each support column 21. A movable limiting structure 3 is provided directly above the base 1. The movable limiting structure 3 includes a movable groove 31 sleeved on the two support columns 21. A threaded block 32 is welded and fixed to the outer wall of the movable groove 31, and a threaded rod 33 is threadedly connected to the threaded block 32. A top seat 5 is provided near the top of each support column 21, and a [missing information - likely a design feature] is provided at the center of the top surface of the top seat 5. The device has a battery slot 6. A controller 7 is located on the top surface of the top seat 5 near the battery slot 6. A power unit 4 is located at the bottom of the top seat 5. The power unit 4 includes a motor 41 installed in a groove on the bottom surface of the top seat 5 and a reducer 43 connected to the output shaft of the motor 41 via a telescopic rod 42. A connecting rod 44 is located at the bottom of the reducer 43. A drill bit 8 is connected to the bottom of the connecting rod 44 via a mounting base 45. The power unit 4 adopts a combination design of motor 41 and reducer 43 and is powered by a battery. The controller 7 adopts a micro single-chip microcomputer design and controls the operation and stop of the drill bit 8 via a button.

[0024] Specifically, the base 1 has a round opening, the fixing block 22 at the bottom of the support column 21 is fixed to the top surface of the base 1 by bolts 23, and the fixing block 22 near the top of the support column 21 is fixed to the top surface of the top seat 5 by bolts 23, which facilitates the fixing of the base 1, the support 2 and the top seat 5.

[0025] Specifically, a circular hole is provided at the center of the moving groove 31 for rotatably connecting with the connecting rod 44, and the bottom end of the threaded rod 33 is rotatably connected to the base 1. The circular hole is provided to position the drill bit 8, ensuring that the drill bit 8 operates within a specified range, which is also a structural requirement of this design.

[0026] Furthermore, the output shaft of the motor 41 is coaxially keyed to the telescopic rod 42, and the telescopic rod 42 is coaxially keyed to the reducer 43. The reducer 43 is fixed to the bottom surface inside the moving groove 31 by screws. The reducer 43 is coaxially keyed to the connecting rod 44, and the connecting rod 44 passes through the circular hole inside the moving groove 31. The function of the telescopic rod 42 is to ensure the normal operation of the motor 41 and the reducer 43. During the process of the moving groove 31 rotating and rising with the threaded block 32, the telescopic rod extends and retracts to ensure the normal operation of the drilling work, and can also reduce wear caused by friction and improve the durability of the design.

[0027] Furthermore, the drill bit 8 is connected to the connecting rod 44 via a standard threaded interface. The drill bit 8 passes through a pre-set circular opening inside the base 1. The end of the drill bit 8 connected to the mounting base 45 is provided with a threaded interface to facilitate the replacement of different drill bits to meet the needs of actual work.

[0028] Furthermore, a turntable 34 is welded and fixed to one end of the threaded rod 33 near the top seat 5. A crank handle 35 is integrally formed on the upper surface of the turntable 34. The user can rotate the threaded rod 33 through the crank handle 35. The threaded block 32, which is threadedly connected to the threaded rod 33, will move up and down along the threaded rod 33 with the moving groove 31.

[0029] It should be added that the bottom of the base 1 is provided with several ground nails 9. There are at least four ground nails 9 located at the four corners of the base 1. The ground nails 9 are set in order to meet the design requirements for stable operation when the attached object is slippery. Almost all the components in this design are connected by bolts or threads, which makes disassembly and installation convenient.

[0030] In addition, the controller 7 is electrically connected to the motor 41 via a wire, and the controller 7 and the motor 41 are also electrically connected to the battery installed in the battery compartment 6 via wires, so that the battery powers the entire device.

[0031] Finally, it should be noted that the components involved in this utility model, such as the motor 41, reducer 43, and controller 7, are all general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. In the spare parts of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection methods should refer to the working principle of this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0032] When using this simple drilling tool, the user determines the required drill bit model, fixes the drill bit 8 to the connecting rod 44 with threads, then rotates the rocker handle 35 to adjust the position of the moving groove 31 so that the drill bit is in a suitable position for drilling. The battery is installed in the battery slot 6, and then the button of the controller 7 is turned on. The motor 41 will drive the drill bit 8 to rotate under the transmission action of the connecting rod 44, the telescopic rod 42 and the reducer 43, and the drilling tool can then start normal operation.
