Abstract
Description
Technical Field
[0001] This utility model relates to the field of magnetic drill bit protection technology, and in particular to a drill bit protection structure for a mobile magnetic drill. Background Technology
[0002] Magnetic drills, also known as magnetic base drills, are highly efficient and widely used in the drilling and sampling of high-hardness samples during oil extraction.
[0003] When drilling into a product, waste chips are generated. After drilling, the drill bit will also absorb a large amount of dust and waste chips. If it is not cleaned, it will affect the next use of the drill bit. Therefore, a protective structure for a mobile magnetic drill bit is proposed. Utility Model Content
[0004] The main purpose of this utility model is to provide a protective structure for a mobile magnetic drill bit, which can effectively solve the problems in the background art by cleaning the waste chips on the drill bit with a cleaning brush.
[0005] To achieve the above objectives, this utility model provides a protective structure for a mobile magnetic drill bit, including a first sleeve, a second sleeve, a pressure button, and a cleaning brush;
[0006] One end of the first sleeve is connected to a locking component. The first sleeve is provided with two sets of cleaning guide rails. The two sets of cleaning guide rails are connected end to end. The cleaning guide rails include a first guide rail and a second guide rail. The two ends of the first guide rail are respectively close to the two ends of the first sleeve. The spiral angle of the second guide rail is 180°. One end of the first guide rail is connected to one end of the second guide rail. A slider is slidably installed inside the cleaning guide rail.
[0007] The second sleeve is fitted around the first sleeve, and the second sleeve has a groove, in which the slider is rotatably mounted.
[0008] The pressure button is rotatably connected to the side of the second sleeve away from the locking assembly via a bearing, and the pressure button is connected to the first sleeve via a spring;
[0009] The cleaning brush is connected to the slider via a mounting base, and the cleaning brush is located inside the first sleeve.
[0010] Based on the above technical solution, the present invention can be further improved as follows.
[0011] Furthermore, the locking assembly includes multiple locking blocks and a locking knob. The multiple locking blocks are spaced apart at one end of the first sleeve along the circumferential direction. The locking knob is threadedly connected to the multiple locking blocks, and the diameters of the rings formed by the two ends of the multiple locking blocks are different.
[0012] Furthermore, the bearing is detachably connected to the pressure button.
[0013] Furthermore, the cleaning brush is arranged in a ring shape, and the bristles of the cleaning brush are mounted obliquely on the mounting base.
[0014] Furthermore, a toothed ring is provided at the end of the first sleeve away from the locking assembly, the toothed ring being used to clean the cleaning brush.
[0015] The beneficial effects of this utility model are as follows: This utility model provides a protective structure for a mobile magnetic drill bit, which has the following advantages:
[0016] 1. This utility model, by setting up a cleaning brush, allows the operator to press a pressure button, which pushes the second sleeve towards the locking component. The second sleeve then moves the slider towards the locking component. The slider moves from the end of the first guide rail near the pressure button to the end away from the pressure button, while the spring is compressed. When the operator releases the pressure button, the spring force causes the pressure button to move away from the locking component, and the slider moves from the end of the second guide rail away from the pressure button to the end near the pressure button. The second guide rail is spiral-shaped, and the slider drives the cleaning brush in a spiral motion, thus cleaning the debris from the drill bit. This solves the problem that after drilling, the drill bit will absorb a large amount of dust and debris, which, if not cleaned properly, will affect the next use of the drill bit.
[0017] 2. This utility model, by setting a toothed ring, when the slider is located near the pressure button, the bristles of the cleaning brush cross the teeth of the toothed ring. During one reciprocating crossing process, the teeth of the toothed ring trap the debris on the cleaning brush and drop it to the side of the pressure button. The pressure button is detachably connected to the bearing, so the debris can be removed by disassembling the pressure button.
[0018] 3. This utility model provides protection for the drill bit by setting a first sleeve that is fitted around the drill bit. At the same time, the first sleeve is provided with a cleaning guide rail to prevent water from condensing on the drill bit during the cooling process after use, which would otherwise cause the drill bit to rust.

[0029] like Figure 1-4 As shown, this utility model provides a protective structure for a mobile magnetic drill bit, including a first sleeve 1, a second sleeve 9, a pressure button 12, and a cleaning brush 14;
[0030] One end of the first sleeve 1 is connected to a locking component 2. The first sleeve 1 is provided with two sets of cleaning guide rails 5, which are connected end to end. The cleaning guide rail 5 includes a first guide rail 6 and a second guide rail 7. The two ends of the first guide rail 6 are close to the two ends of the first sleeve 1, and the spiral angle of the second guide rail 7 is 180°. One end of the first guide rail 6 is connected to one end of the second guide rail 7. A slider 8 is slidably installed inside the cleaning guide rail 5.
[0031] The locking assembly 2 includes multiple locking blocks 3 and a locking knob 4. The multiple locking blocks 3 are spaced apart along the circumferential direction at one end of the first sleeve 1. The locking knob 4 is threadedly connected to the multiple locking blocks 3, and the diameters of the rings formed by the two ends of the multiple locking blocks 3 are different.
[0032] The second sleeve 9 is fitted around the first sleeve 1, and the second sleeve 9 is provided with a groove 10, and the slider 8 is rotatably installed in the groove 10;
[0033] The pressure button 12 is rotatably connected to the side of the second sleeve 9 away from the locking assembly 2 via a bearing 11. The bearing 11 and the pressure button 12 are detachably connected. The pressure button 12 and the first sleeve 1 are connected via a spring 13.
[0034] The cleaning brush 14 is connected to the slider 8 via the mounting base 15. The cleaning brush 14 is located inside the first sleeve 1. The cleaning brush 14 is arranged in a ring shape, and the bristles of the cleaning brush 14 are installed obliquely on the mounting base 15.
[0035] In this embodiment, a toothed ring 16 is provided at the end of the first sleeve 1 away from the locking component 2, and the toothed ring 16 is used to clean the cleaning brush 14.
[0036] In this embodiment, pressing the pressure button 12 compresses the spring 13, while the slider 8 moves from the end of the first guide rail 6 near the pressure button 12 to the end of the first guide rail 6 away from the pressure button 12. When the pressure button 12 is released, under the elastic force of the spring 13, the pressure button 12 moves away from the locking assembly 2. The slider 8 moves from the end of the second guide rail 7 away from the pressure button 12 to the end of the second guide rail 7 near the pressure button 12. The second guide rail 7 is spiral-shaped, and the slider 8 drives the cleaning brush 14 to make a spiral motion, thus cleaning the waste chips on the drill bit. This solves the problem that after drilling, the drill bit will absorb a lot of dust and waste chips, which will affect the next use of the drill bit if it is not cleaned properly.
[0037] In this embodiment, when the slider 8 is located near the pressure button 12, the bristles of the cleaning brush 14 cross the teeth of the toothed ring 16. During one reciprocating crossing process, the teeth of the toothed ring 16 trap the debris on the cleaning brush 14 and drop it to the side of the pressure button 12. The pressure button 12 is detachably connected to the bearing 11, so the debris can be removed by removing the pressure button 12.
[0038] The working principle is as follows:
[0039] The operator places the used drill bit into the first sleeve 1 and rotates the locking knob 4 to fix the drill bit protective structure to the drill bit. Initially, the slider 8 is located on the cleaning guide 5 near the pressure button 12. The operator presses the pressure button 12, which pushes the second sleeve 9 towards the locking assembly 2. The second sleeve 9 then moves the slider 8 towards the locking assembly 2, from the end of the first guide 6 near the pressure button 12 to the end of the first guide 6 away from the pressure button 12. Simultaneously, the spring 13 is compressed. When the operator releases the pressure button 12, the spring 13 causes the pressure button 12 to move away from the locking assembly 2, and the slider 8 moves away from the second guide 7. When one end of the pressure button 12 moves closer to the second guide rail 7, which is spiral in shape, the slider 8 drives the cleaning brush 14 to make a spiral motion, thus cleaning the debris on the drill bit. This solves the problem that after drilling, the drill bit will absorb a lot of dust and debris, which will affect the next use of the drill bit if it is not cleaned properly. When the slider 8 is located close to the pressure button 12, the bristles of the cleaning brush 14 cross the teeth of the toothed ring 16. During one reciprocating crossing process, the teeth of the toothed ring 16 intercept the debris on the cleaning brush 14 and drop it to one side of the pressure button 12. The pressure button 12 is detachably connected to the bearing 11, so the debris can be removed by removing the pressure button 12.
