Abstract
The utility model discloses a structure for pulling out a bolt without a top. The structure comprises a bolt without a top, which is in threaded connection with a connecting piece, wherein the bolt without the top is provided with a thread hole having the same central line as the bolt without the top, the thread hole is in threaded connection with a small bolt, and a direction of turning of a screw thread of the thread hole is opposite to a direction of turning of a screw thread of the bolt without the top. By adopting the technical scheme, the small bolt is clamped by a wrench so as to be screwed into the thread hole, the direction of turning of the screw thread of the thread hole is opposite to the direction of turning of the screw thread of the bolt without the top, so that the bolt without the top is driven to be unscrewed in a screwing process of the small bolt, thus the bolt without the top is dismounted from the connecting piece. The structure, provided by the utility model, has the advantages of easiness in mastering in application, convenience and fastness, and capability of preventing the connecting piece from deformation and damage due to external damage.
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.
Claims (1)
1. a decollation bolt takes out structure, it is characterized in that: 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.
