Description

Borer tool convenient to equipment

Technical Field

The utility model belongs to the technical field of drilling tool processing application, and particularly relates to a drilling tool convenient to assemble.

Background

The drill tool is a working tool for rock drilling, namely a connecting rod drill shank, a drill rod, a connecting sleeve, a drill bit, an integral drill rod and the like. In the prior art, in order to ensure the connection stability of the drill bit and the drill rod, a mode of threaded connection of the drill bit and the drill rod is generally adopted.

Although this connection ensures the stability of the connection between the drill bit and the drill shank, it is often replaced due to the fact that the drill bit is a consumable, and the length of the thread is long, which results in a long replacement time.

Disclosure of utility model

Aiming at the technical problems of the prior drill bit and drill rod threaded connection, the utility model provides the drill tool which is reasonable in design, simple in structure, convenient to assemble and quick to assemble.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a drill tool convenient to assemble, which comprises a drill bit and a drill rod, wherein a connecting hole is formed in the bottom of the drill bit, connecting threads are formed in the end part of the drill rod, internal threads matched with the connecting threads are formed in the connecting hole, and the connecting threads are double-line threads.

Preferably, the connecting screw thread includes a double-thread provided at a front end and a single-thread provided at a rear end.

Preferably, the pitch of the single thread is one half of that of the double thread, and the major diameter of the single thread is larger than that of the double thread.

Compared with the prior art, the utility model has the advantages and positive effects that:

1. The utility model provides a drill tool convenient to assemble, which changes the existing drill rod thread structure from single thread to double thread, so that the assembly speed between the drill bit and the drill rod is improved under the condition of not changing the core part of the drill rod, thereby being convenient for replacing the drill bit.

in the drawings, 1, a drill bit; 2. a drill rod; 3. a connecting thread; 31. a double thread; 32. single thread.

Detailed Description

In order that the above objects, features and advantages of the utility model will be more clearly understood, a further description of the utility model will be rendered by reference to the appended drawings and examples. It should be noted that, without conflict, the embodiments of the present utility model and features in the embodiments may be combined with each other.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model, but the present utility model may be practiced otherwise than as described herein, and therefore the present utility model is not limited to the specific embodiments of the disclosure that follow.

Embodiment 1, as shown in fig. 1, the present embodiment aims to improve the installation speed of the drill tool while ensuring the product quality, so as to facilitate the use of the drill tool, and therefore, the drill tool provided in this embodiment, which is convenient for assembly, comprises a drill bit 1 and a drill rod 2, wherein a connecting hole is provided at the bottom of the drill bit 1, a connecting thread 3 is provided at the end of the drill rod 2, and an internal thread matched with the connecting thread 3 is provided in the connecting hole, and the above structure is a conventional common structure, and therefore, in this embodiment, detailed description is omitted.

For quick assembly and easy replacement, the threaded connection is most convenient, for which purpose the connecting thread 3 is a double thread 31 in the present embodiment. The double thread 31 is designed relative to the single thread, and achieves an increase in pitch without reducing the diameter of the core of the drill rod 2, thereby increasing the distance of one turn of rotation extending in or out, and achieving rapid assembly.

Considering that the stability of the double thread 31 is inferior to that of the single thread 32, for this reason, in the present embodiment, the connecting thread 3 includes the double thread 31 provided at the front end and the single thread 32 provided at the rear end. In this way, the quick assembly of the double thread 31 is utilized, and then the locking of the single thread 32 is utilized again, thereby securing the stability of the fixation.

Considering the design of the front-end double-thread 31 and the rear-end single-thread 32, it is necessary that the pitch of the single-thread 32 is identical to that of the double-thread 31, which has a problem of a low service life of the thread, and for this reason, in this embodiment, the pitch of the single-thread 32 is one-half of the double-thread 31 and the major diameter of the single-thread 32 is larger than that of the double-thread 31. The large diameter of the single thread 32 is larger than that of the double thread 31 so as to not affect the insertion of the double thread 31, and thus, the assembly speed can be ensured, the connection strength can be ensured, and the fixing stability can be ensured.

The present utility model is not limited to the above-mentioned embodiments, and any equivalent embodiments which can be changed or modified by the technical content disclosed above can be applied to other fields, but any simple modification, equivalent changes and modification made to the above-mentioned embodiments according to the technical substance of the present utility model without departing from the technical content of the present utility model still belong to the protection scope of the technical solution of the present utility model.
