Description

Technical Field

[0001] The utility model relates to the technical field of drilling tools, in particular to a novel drilling device. Background Art

[0002] A considerable part of the various pipeline laying channels in buildings and structures is carried out in subsequent work, and it is necessary to drill holes in the floors or ceilings of the upper and lower floors, and in adjacent or external panels for communication. Completed or in-use buildings and structures often have new, additional or modified pipeline laying, which all require drilling. For holes with a diameter ranging from three to more than ten centimeters, it is difficult to control the positioning and stability of the drill bit at the beginning of drilling. During vibration and slippage, they often deviate from the set position, especially when facing the complete and aesthetic decorative surfaces of wood or other materials. This vibration and slippage often cause them to break and scratch, affecting the overall beauty and integrity, and even causing rework losses. For the laying of rigid pipelines, especially multi-porous concentric corresponding rigid pipelines, deviation and displacement often bring many difficulties and inconveniences to the subsequent installation.

[0003] Moreover, in the existing large-diameter drilling tools, after drilling is completed, the drilled part is often left in the drilling tool, which not only affects the reuse of the drilling tool, but is also inconvenient to remove, causing many inconveniences to the construction.

[0004] Therefore, a novel drilling device is proposed to solve the existing deficiencies. Utility Model Content

[0022] In order to make the purpose, technical solution and advantages of the utility model embodiments clearer, the technical solution in the utility model embodiments will be clearly and completely described below in conjunction with the drawings in the utility model embodiments. Obviously, the described embodiments are part of the utility model embodiments, not all of the embodiments. Generally, the components of the utility model embodiments described and shown in the drawings here can be arranged and designed in various different configurations.

[0023] In the description of the utility model embodiments, it should be noted that if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate the orientation or position relationship, they are based on the orientation or position relationship shown in the drawings, or the orientation or position relationship in which the utility model product is usually placed when in use. They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0024] In addition, the terms "horizontal", "vertical", "overhanging" and the like do not mean that the components must be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0025] In the description of the embodiments of the utility model, "a plurality of" means at least 2.

[0026] In the description of the utility model embodiments, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood according to specific circumstances.

[0027] Combined with Figure 1-5 As shown, a novel drilling device comprises a screw rod 1, a rotating sleeve 2 and a drill bit 3;

[0028] The rotating sleeve 2 is a hollow cylindrical structure with one end open. Specifically, the specification and size of the rotating sleeve 2 can be set according to actual conditions to meet the drilling requirements of different hole diameters.

[0029] The open end of the rotating sleeve 2 is provided with a gear ring 4, and the end of the rotating sleeve 2 is coaxially provided with a connecting seat 5, and the rotating sleeve 2 is fixedly connected to the connecting seat 5.

[0030] The screw rod 1 is threadedly connected to the connecting seat 5 and one end extends into the rotating sleeve 2. During implementation, the screw rod 1 is threadedly connected to the connecting seat 5. In this embodiment, the screw rod 1 can move along the axial direction of the connecting seat 5.

[0031] One end of the screw rod 1 located in the rotating sleeve 2 is provided with a limit plate 6 abutting against the rotating sleeve 2. During implementation, the limit plate 6 is provided on the screw rod 1 to ensure the stability of the relative position between the screw rod 1 and the rotating sleeve 2. Specifically, when drilling, during the drilling process of the rotating sleeve 2, the limit plate 6 abuts against the rotating sleeve 2, so that the relative position between the screw rod 1 and the rotating sleeve 2 remains fixed.

[0032] Furthermore, the stop plate 6 is provided with a plurality of protrusions 10 along the axis line for contacting the rotating sleeve 2. The matching arrangement of the protrusions 10 on the stop plate 6 and the rotating sleeve 2 can avoid the screw rod 1 and the rotating sleeve 2 from getting stuck during the drilling process.

[0033] The other end of the screw rod 1 is provided with a connector 9 connected to the hand drill. Through the setting of the connector 9, the connection between the drilling device and the hand drill can be achieved.

[0034] The end of the screw rod 1 is provided with a mounting groove 7, and the drill bit 3 is plugged into the screw rod 1 through the mounting groove 7. Specifically, the mounting groove 7 is coaxially arranged with the screw rod 1. Through the setting of the mounting groove 7, a detachable connection between the drill bit 3 and the screw rod 1 can be achieved, and the replacement of the drill bit 3 can be convenient.

[0035] The screw rod 1 is provided with a fastening screw 8 that abuts against the drill bit 3. During implementation, the fastening screw 8 is a countersunk screw. By providing the fastening screw 8, the drill bit 3 can be fixedly connected to the screw rod 1.

[0036] One end of the drill bit 3 extends to the outside of the rotating sleeve 2 to facilitate confirmation of the drilling position.

[0037] When the utility model is implemented, the drill bit 3 drills into the part to be drilled, which can effectively control the centrifugal force generated by the rotating sleeve 2 when rotating at high speed, so that the rotating sleeve 2 can enter the part to be drilled to drill. When the rotating sleeve 2 is drilling, the rotation of the screw rod 1 drives the rotating sleeve 2 to rotate. At this time, the limit plate 6 abuts against the rotating sleeve 2 to ensure the fixation of the position between the screw rod 1 and the rotating sleeve 2. After the drilling is completed, the drilled part is located in the rotating sleeve 2. The screw rod 1 can be rotated in the opposite direction to extend the screw rod 1 out of the rotating sleeve 2. At the same time, the drilled part can be pushed out by the limit plate 6, which is convenient for cleaning.

[0038] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
