Description

Technical Field

[0001] The present application relates to the technical field of drill bits, and in particular to a high-strength drill bit suitable for drilling holes in a variety of plate materials. Background Art

[0002] A drill bit is a tool used to create through holes or blind holes in solid materials, as well as to expand existing holes. Common drill bits include twist drills, spade drills, center drills, deep hole drills, and trepanning drills. The drill bit is typically mounted on a drilling rig, which drives the drill bit to drill holes in plates or other objects.

[0003] The existing drill bit mainly consists of a drill tip, a main cutting edge, a spiral groove and other structures. The drill tip protrudes toward the bottom. When the drill tip drills a hole in a plate, the drill tip is easily worn, thereby reducing the service life of the drill bit.

[0004] Therefore, there is an urgent need for a high-strength drilling rig drill bit suitable for drilling holes in a variety of plates to solve the problem that the drill bit is easily worn. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the present application provides a high-strength drill bit suitable for drilling holes in a variety of plates, which has the advantage of increasing the service life of the drill bit and solving the problem of the drill bit being easily worn.

[0006] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a high-strength drill bit suitable for drilling holes in various plates, comprising a connecting rod, a drill bit part, a connecting column, a connecting piece part and a connecting seat part, wherein the drill bit part is located at the bottom of the connecting rod and wrapped around the outside of the connecting rod, and the two ends of the connecting column are respectively fixedly connected to the top of the connecting rod and the bottom of the connecting piece part, and the connecting seat part is fixed to the top of the connecting piece part, and the connecting rod, drill bit part, connecting column, connecting piece part and connecting seat part are integrally formed.

[0007] Preferably, the upper outer side of the drill bit part is an arc-shaped surface and the lower outer side is an inclined surface. The outer side of the drill bit part is composed of four groups of metal plates. The bottom of the drill bit part is cut with a cut surface, and the cut surface is formed at the intersection of the metal plates at the bottom of the drill bit part.

[0008] The upper outer side of the drill bit is an arc-shaped surface and the lower outer side is an inclined surface, and the inner side is supported by a connecting rod, which improves the strength of the drill bit.

[0009] Preferably, the connecting seat portion and the connecting column are square column structures.

[0010] The connecting seat part and the connecting column are square column structures, which improves the strength of the drill bit.

[0011] In summary, this application has at least one of the following beneficial effects:

[0012] The high-strength drill bit suitable for drilling holes in various plates has a drill bit part with an arc-shaped upper surface and an inclined lower surface on the outer side, and is supported by a connecting rod on the inner side, thereby improving the strength of the drill bit. When the drill bit part drills holes in various plates, the drill tip at the lower part of the drill bit part is not easily worn, thereby improving the service life of the drill bit. The connecting seat part can be inserted into the head of the drill. Since the connecting seat part has a square structure, the connecting seat part is not easy to slide or fall off, thereby improving the stability of the drill bit when drilling. The formation of the cut surface helps the drill bit part to drill holes, thereby improving the drilling rate of the drill bit part. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0019] See also Figure 1-3, a high-strength drilling rig drill bit suitable for drilling holes in various plates, including a connecting rod 1, a drill bit part 2, a connecting column 3, a connecting piece part 4 and a connecting seat part 5. The drill bit part 2 is located at the bottom of the connecting rod 1 and wrapped around the outside of the connecting rod 1. The two ends of the connecting column 3 are fixedly connected to the top of the connecting rod 1 and the bottom of the connecting piece part 4 respectively. The connecting seat part 5 is fixed to the top of the connecting piece part 4. The connecting seat part 5 and the connecting column 3 are a square column structure. The connecting rod 1, the drill bit part 2, the connecting column 3, the connecting piece part 4 and the connecting seat part 5 are integrally formed. The upper part of the outer side of the drill bit part 2 is an arc-shaped surface and the lower part is an inclined surface. The arc-shaped surface can reduce the wear of the plate on the drill bit part 2. The outer side of the drill bit part 2 is composed of four groups of metal plates. The bottom of the drill bit part 2 is cut with a cutting surface 6. The cutting surface 6 is formed at the intersection of the metal plates at the bottom of the drill bit part 2. The formation of the cutting surface 6 helps the drill bit part 2 to drill holes, thereby improving the drilling rate of the drill bit part 2.

[0020] Through the above technical solution, the connecting seat part 5 can be inserted into the head of the drill rig, and the head of the drill rig clamps and fixes the connecting seat part 5. Since the connecting seat part 5 is a square column structure, the connecting seat part 5 is not easy to slide or fall off, thereby improving the stability of the drill bit when drilling. The outer side of the connecting rod 1 and the connecting column 3 is a flat structure without a groove, thereby improving the strength of the overall structure of the drill bit. The outer side of the drill bit part 2 is composed of four groups of arc plates, and the inner side is supported by the connecting rod 1, which further improves the strength of the drill bit. When the drill bit part 2 drills holes in various plates, the drill tip at the bottom of the drill bit part 2 is not easy to be worn, thereby improving the service life of the drill bit.

[0021] Although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
