Abstract
The invention discloses a lock bolt with a groove. The lock bolt with the groove comprises a bolt main body, threads and a lock groove, wherein the threads are formed on the bolt main body; one end close to the threads is a threaded end face; the lock groove is formed perpendicular to the threaded end face along the central axis of the bolt; and after the bolt is tightened, a wedge can be hit into the lock groove to change the structure of the bolt, so that a nut is blocked and cannot come off and a locking aim is fulfilled. Therefore, the lock bolt with the groove has the advantages of high reliability, simple structure, convenience for manufacture, low cost and the like, and has a wide market prospect in the fastener market.
Description
Technical field
The present invention relates to fastener areas, particularly relate to a kind of trough of belt chek bolt.
Background technique
Bolt is the most frequently used fastening pieces of people, and it is simple in structure, and is easy to use, respond well, is widely used in various occasions.But, in the occasion of some existence vibrations, be used for fastening bolt and often take place to become flexible, cause to connect and throw off, machine failure, even cause security incident, make for this reason and can become very urgent and important by effectively anti-loosening bolt.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of trough of belt chek bolt, prevent that by increasing antiratchetting groove bolt nut from getting loose, have the unfailing performance height, simple in structure, make advantages such as easy, with low cost, in fastening piece market market prospects are widely arranged simultaneously.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: a kind of trough of belt chek bolt is provided, comprise: bolt body, screw thread and antiratchetting groove, screw thread is arranged on the bolt body, and an end of close screw thread is the screw thread end face, along the bolt central axial direction, be provided with antiratchetting groove perpendicular to the screw thread end face, after the bolt bolt was tight, an available wedge was squeezed into antiratchetting groove, changed bolt arrangement and made that nut is stuck and can't deviate from.Reach the locking purpose.
In a preferred embodiment of the present invention, described trough of belt chek bolt surface is provided with screw thread.
In a preferred embodiment of the present invention, the screw thread end face of described trough of belt chek bolt is provided with antiratchetting groove.
In a preferred embodiment of the present invention, the antiratchetting groove of described trough of belt chek bolt is by the bolt central axis and perpendicular to the screw thread end face.
The invention has the beneficial effects as follows: trough of belt chek bolt of the present invention have the unfailing performance height, simple in structure, make advantages such as easy, with low cost, in fastening piece market market prospects are widely arranged simultaneously.
Description of drawings
In order to be illustrated more clearly in the technological scheme in the embodiment of the invention, the accompanying drawing of required use is done to introduce simply in will describing embodiment below, apparently, accompanying drawing in describing below only is some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of trough of belt chek bolt one preferred embodiment of the present invention;
Fig. 2 is scheme of installation of the present invention;
The mark of each parts is as follows in the accompanying drawing: 1, bolt body, 2, go up workpiece, 3, workpiece down, 4, the cutter screw thread, 5, nut, 6, antiratchetting groove.
Embodiment
To the technological scheme in the embodiment of the invention be clearly and completely described below, obviously, described embodiment only is a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making all other embodiments that obtain under the creative work prerequisite.
See also Fig. 1 to Fig. 2, the embodiment of the invention comprises:
A kind of trough of belt chek bolt comprises: bolt body 1, screw thread 4 and antiratchetting groove 6, screw thread 4 are arranged on the bolt body 1, and an end of close screw thread 4 is the screw thread end face, along the bolt central axial direction, is provided with antiratchetting groove 6 perpendicular to the screw thread end face.
Described trough of belt chek bolt surface is provided with screw thread, screws in for nut.
The screw thread end face of described trough of belt chek bolt is provided with antiratchetting groove, can make the bolt arrangement distortion after making nut screw in, and avoids nut to screw out.
The antiratchetting groove of described trough of belt chek bolt has structural strength and anti-loosening property preferably by the bolt central axis and perpendicular to the screw thread end face.
Locking working procedure is:
After bolt is good with fixed by nut, a wedge shape iron block is placed in the antiratchetting groove, knock several times with hammer, make the both sides screw thread outwards open, because screw thread and diameter change, make nut to screw out, finish fastening operation.
The beneficial effect of electric driving tool post of the present invention is:
One, by offering antiratchetting groove, simple in structure, anti-loosing effect is good;
Two, manufacturing is easy, with low cost;
Three, in the fastener field extensive market is arranged;
The above only is embodiments of the invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes description of the present invention to do; or directly or indirectly be used in other relevant technical field, all in like manner be included in the scope of patent protection of the present invention.
Claims (3)
1. a trough of belt chek bolt is characterized in that, comprising: bolt body, screw thread and antiratchetting groove, screw thread are arranged on the bolt body, and an end of close screw thread is the screw thread end face, along the bolt central axial direction, is provided with antiratchetting groove perpendicular to the screw thread end face.
2. trough of belt chek bolt according to claim 1 is characterized in that, described antiratchetting groove is perpendicular to the screw thread end face and pass through the axle center.
