Abstract
The utility model discloses an adapter of connecting self -drilling stock and drill bit belongs to the connecting piece of jointed rod and drill bit, one kind is aimed at providing and different specification and dimension's the self -drilling stock and the connecting piece of drill bit linkage convention can be realized. It includes the transitional coupling cover, the surface of transitional coupling cover (2) have with the internal surface of the external screw thread of drill bit trousers body looks adaptation, this transitional coupling cover have with the internal thread of stock looks adaptation. The utility model discloses simple structure, convenient to use, both reducible self -drilling stock specification quantity, improve its commonality, can reduce user's the use cost and the work load of management again, the transition connection piece of a jointed rod and drill bit.
Description
Technical field
This utility model relates to a kind of connector for jointed rod Yu drill bit, particularly relates to a kind of adapter connecting automatic anchor pole and drill bit.
Background technology
At present, widely used anchor pole and drill bit are generally all be directly connected to by screw thread, although fairly simple, but only the anchor pole of same specification could realize being connected with drill bit. But, owing to the specification of drill bit is a lot, therefore also to mate the anchor pole of respective numbers, dimension; Not only increase the workload producing and managing, but also the waste of the means of production can be caused.
Summary of the invention
For the drawbacks described above existed in prior art, this utility model aims to provide a kind of adapter connecting automatic anchor pole and drill bit, and it can realize automatic anchor pole and the drill bit matching connection of different specification size.
To achieve these goals, this utility model is by the following technical solutions: it includes transition adapter sleeve; There is the external screw thread suitable with drill bit diaper body on the surface of transition adapter sleeve, the inner surface of this transition adapter sleeve has the female thread suitable with anchor pole.
Described external screw thread and female thread are corrugated thread.
Compared with the prior art, this utility model is owing to have employed technique scheme, the matching connection between automatic anchor pole and drill bit is realized by the transition adapter sleeve with external screw thread and female thread, therefore only need to change transition adapter sleeve can realize an anchor pole and be connected with the drill bit of different size, greatly reduce the specification quantity of automatic anchor pole, improve the versatility of automatic anchor pole, not only reduced the use cost of user, but also decreased and produce and the workload of management. This utility model simple in construction, easy to use, low cost of manufacture.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: anchor pole 1, transition adapter sleeve 2, drill bit diaper body 3.
Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.
As shown in Figure 1: there is the waveform external screw thread suitable with drill bit diaper body 3 on the surface of transition adapter sleeve 2, the inner surface of this transition adapter sleeve has the waveform female thread suitable with anchor pole 1.
Claims (2)
1. the adapter connecting automatic anchor pole and drill bit;Including transition adapter sleeve; It is characterized in that: there is the external screw thread suitable with drill bit diaper body on the surface of transition adapter sleeve (2), the inner surface of this transition adapter sleeve has the female thread suitable with anchor pole.
