[0025] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.
[0026] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.
[0027] Example 1
[0028] like Figure 1-5 As shown, an embodiment of the utility model provides a diamond drill bit, including a mounting seat 1 and a mounting plate 5, a card slot 11 is opened at the middle end of the bottom of the mounting seat 1, the mounting plate 5 is clamped in the card slot 11, a drill body 4 is arranged at the bottom of the mounting plate 5, reserved cavities 18 are opened on both sides of the inner surface of the mounting seat 1, a reset spring 16 is arranged on the outer side of the reserved cavity 18, a movable block 17 is arranged on the inner side of the reset spring 16, a movable rod 10 is welded to the bottom of the movable block 17, an insert block 12 is welded to the inner side of the movable block 17, slots 13 are opened on both sides of the mounting plate 5, and the insert block 12 is inserted into the slot 13.
[0029] By clamping the mounting plate 5 into the movable rod 10, the reset spring 16 is then deformed due to the force and drives the movable block 17 to move inward, and the movable block 17 drives the plug block 12 to move inward and is plugged into the slot 13, the mounting plate 5 is limited, and the installation of the drill body 4 is completed. Since the two sides are limited by the plug-in block 12, it is not easy to fall off during high-speed rotation, thereby improving the overall service life.
[0030] Example 2
[0031] In one embodiment, connecting blocks 6 are provided on both sides of the bottom of the mounting seat 1, and the inner side of the connecting block 6 is movably connected to the limit plate 9 through a rotating shaft, and an elastic limit block 8 is welded to one end of the limit plate 9. Limiting grooves 14 are provided on both sides of the bottom of the mounting seat 1, and the elastic limit block 8 is inserted into the limit groove 14. Slide grooves 15 are provided on the front and rear sides of the reserved cavity 18, and sliders 19 are welded on the front and rear sides of the movable block 17, and the slider 19 is slidably connected in the slide groove 15. Reserved grooves 7 are provided on the left and right sides of the bottom of the mounting seat 1, and the bottom of the movable rod 10 passes through the reserved groove 7 and extends to the mounting seat 1. The bottom and top of the mounting seat 1 are provided with a connecting plate 2, the top of the connecting plate 2 is provided with a rotating motor 3, and the output end of the rotating motor 3 is fixedly connected to the mounting seat 1, the drill body 4 includes a base layer 401, a high-strength layer 402 and a wear-resistant layer 403, the high-strength layer 402 is provided on the outer surface of the base layer 401, the wear-resistant layer 403 is coated on the outer surface of the high-strength layer 402, the thickness of the high-strength layer 402 is 20mm-21mm, the thickness of the wear-resistant layer 403 is 1.5mm-1.7mm, the high-strength layer 402 is a nickel-chromium alloy, and the wear-resistant layer 403 is a modified hydroxyl acrylic resin.
[0032] By setting the connecting block 6, the limit plate 9, the elastic limit block 8 and the limit groove 14, the outer side of the movable rod 10 can be blocked to prevent it from being displaced after installation and causing the insert block 12 to loosen, thereby further improving the limiting effect. By setting the slide groove 15 and the slider 19, the moving trajectory of the movable block 17 can be limited to improve its stability during movement. By setting the reserved groove 7, the moving trajectory of the movable rod 10 can be limited to prevent it from being offset during movement. By setting the high-strength layer 402 and the wear-resistant layer 403, high-strength and wear-resistant effects can be achieved, thereby improving the strength of the drill body 4 and the surface wear resistance.
[0033] When the utility model is working: first, by pulling the movable rod 10 outward, the movable block 17 is driven to move outward, and the movable block 17 squeezes the return spring 16 and deforms due to the influence of force, then the mounting plate 5 is clamped in the clamping groove 11, and then the movable rod 10 is released. At this time, the return spring 16 is deformed again due to the influence of the loss of force and drives the movable block 17 to move inward, and the movable block 17 drives the plug block 12 to move inward and plug into the slot 13, completing the installation of the drill body 4. Because its two sides are limited by the plug-in block 12, it can make it not easy to fall off during high-speed rotation, thereby improving the overall service life. Finally, pull the limit plate 9 to insert the elastic limit block 8 into the limit groove 14. At this time, the limit plate 9 is located on the outside of the movable rod 10, which can block the outside of the movable rod 10 to prevent it from being displaced after installation and then causing the plug block 12 to loosen, thereby further improving the limiting effect.
[0034] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
