Abstract
本实用新型公开了一种断头螺栓取出结构，包括螺纹连接在连接件内的断头螺栓，断头螺栓上开设有与断头螺栓同中心线的螺纹孔，螺纹孔内螺纹连接有小螺栓，螺纹孔的螺纹旋向与断头螺栓的螺纹旋向相反。采用上述技术方案，使用扳手卡住小螺栓向螺纹孔内旋进，由于螺纹孔内的螺纹旋向与断头螺栓的螺纹旋向相反，在小螺栓旋进过程中，就带动断头螺栓缓慢地旋出，这样就将断头螺栓从连接件内拆卸下来。本实用新型在应用中易于掌握，方便快捷，且保证连接件不受外力破坏而变形损坏。
The utility model discloses a structure for taking out a dead end bolt, which comprises a dead end bolt which is threadedly connected in a connecting piece, a threaded hole which is concentric with the dead end bolt is opened on the dead end bolt, and a small bolt is threaded in the threaded hole , the thread rotation direction of the threaded hole is opposite to that of the broken head bolt. Using the above technical solution, use a wrench to hold the small bolt and screw it into the threaded hole. Since the thread direction in the threaded hole is opposite to that of the broken bolt, during the screwing process of the small bolt, the broken bolt will be driven slowly. Unscrew the stud bolts out of the connecting piece. The utility model is easy to grasp in application, is convenient and quick, and ensures that the connecting parts are not damaged by external force and deformed and damaged.
Description
Technical field
The utility model belongs to the cigarette production technical field, relates in particular to a kind of decollation bolt and takes out structure.
Background technique
In machinery, it is a kind of Placement commonly used that bolt connects, bolt is connected to some occasion, such as outdoor, because environment is abominable, bolt carbonization or the dead phenomenon of becoming rusty are serious, often cause in the demounting bolt process between some bolt heads and the body of bolt bottom to disconnect, the body of bolt is difficult to take out, and adopts not only complex operation of conventional method (welding new bolt head card, boring square steel wedging etc.), and easily cause link to damage, lose more than gain.
The model utility content
The utility model provides a kind of easy operating, safe and reliable decollation bolt to take out structure in order to solve deficiency of the prior art.
For solving the problems of the technologies described above, the utility model adopts following technological scheme: a kind of decollation bolt takes out structure, comprise the decollation bolt that is threaded in the link, offer the tapped hole with the concentricity line of decollation bolt on the decollation bolt, the tapped hole internal thread is connected with stove bolt, and the thread rotary orientation of tapped hole is opposite with the thread rotary orientation of decollation bolt.
Adopt technique scheme, use spanner to block stove bolt precession in the tapped hole, because the thread rotary orientation in the tapped hole is opposite with the thread rotary orientation of decollation bolt, in stove bolt precession process, just drive decollation bolt and screw out lentamente, so just decollation bolt is disassembled in link.The utility model is easy to grasp in application, and is convenient and swift, and guarantees that link is not subjected to outside destroy and deformed damaged.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of decollation bolt of the present utility model takes out structure, comprise the decollation bolt 2 that is threaded in the link 1, offer the tapped hole 3 with decollation bolt 2 concentricity lines on the decollation bolt 2, tapped hole 3 internal threads are connected with stove bolt 4, and the thread rotary orientation of tapped hole 3 is opposite with the thread rotary orientation of decollation bolt 2.
During operation, use spanner to block stove bolt 4 to tapped hole 3 interior precessions, because the thread rotary orientation in the tapped hole 3 is opposite with the thread rotary orientation of decollation bolt 2, in stove bolt 4 precession processes, just drive decollation bolt 2 and screw out lentamente, so just decollation bolt 2 is disassembled in link 1.
