Abstract
The utility model relates to a contracting friction-type check release bolt, belonging to the technical field of F16B contracting or fixing components or machinery parts, which is characterized in that: a through holes (3) is axially arranged in the centers of a bolt body (1) and a hexahedron (2), and one to 3 displacement grooves are axially arranged on the near end of the threaded part of the bolt; the through holes (3) are connected with a locking shaft (4), threads (5) and (8) are meshed and enlarge an expansion angle (7) and then are connected with an adjusting nut (9). The bolt body (1) is connected with a workpiece thread plate (10) and a workpiece connection plate (11) in turn, then the adjusting nut (9) is screwed, the process of locking is finished; when the nut (9) is loosened, the unlocking process is completed.
Description
Technical field:
The utility model relates to that the fastening or fixed component of F16B and machine parts use, the rise locking release screw bolt technical field of angle, displacement slot that having splashes.
Background technique:
In the prior art, bolt is a kind of fastening piece of extensive use.In order to prevent that bolt from getting loose, often adopt measures such as spring washer, pin.However, be difficult to avoid bolt looseness, thereby, brought many harm, as damage equipment, have an accident etc.
I am first to file No. 02209486.5 " supporting the locking release screw bolt of friction type ", though solved the locking of bolt, the problem of locking, release, but for large aperture and frayed substandard link, its locking degree and intensity own is some deficiency obviously.
Summary of the invention:
The utility model provides a kind of deflation friction type locking release screw bolt, makes its locking, dynamics locking, release is stronger, and applicable to the link in various apertures.
Main technical schemes is the body of bolt (1), comprise the bolt hexahedron (2) of an end, its helical thread portion connects workpiece thread plate (10), its screw portion connects workpiece joining plate (11), screws bolt hexahedron (2), and workpiece thread plate (10) closely is connected with workpiece joining plate (11).
The body of bolt (1), comprise bolt hexahedron (2), its central shaft is to establishing a through hole (3), and radially has the displacement slot (6) of several equidirectional or rightabout or any directions at its helical thread portion proximal head, and the endoporus in displacement slot the place ahead is provided with internal thread (8).
The body of bolt (1) comprises the interior lock shaft (4) that connects of the axial hole (3) of hexahedron (2).One end of lock shaft (4) is provided with screw thread (5), 30 °～70 ° angles (7) of rising of splashing are established on the top, screw thread (5) is connected with the internal thread (8) of the body of bolt, and the expanding angle (7) of rising of splashing, strong bonded, on the other end screw thread of lock shaft (4), be connected on the plane of hexahedron (2) again with regulating nut (9).By regulating nut (9), reach the purpose of locking, locking, release.
Thus, the utlity model has the anti-loosening property reliable durable, easy to use, the life-span is long, is easy to locking and characteristics such as release, and the putting more effort of locking, locking, release, and Applicable scope is wideer.
Accompanying drawing and drawing explanation:
Fig. 1 is the structure sectional view that tightens the locking release screw bolt of friction type.
Fig. 2 is the front view of the body of bolt.
Fig. 3 is the front view of lock shaft.
Fig. 4 is locking release screw bolt body and workpiece connection diagram.
Among the figure: 1, the body of bolt, 2, hexahedron, 3, axial hole, 4, lock shaft, 5, outside thread, 6, displacement slot, 7, the angle of rising of splashing, 8, internal thread, 9, regulate nut, 10, the workpiece thread plate, 11, the workpiece joining plate.
Embodiment:
Shown in Fig. 1 .2: give the system body of bolt 1.A kind of is top M30 * 70 screw threads 5, and middle part screw rod, afterbody are the linkage structure of hexahedron 2; Another kind is that two ends have screw thread, and the middle part is a screw rod, and afterbody flexibly connects two kinds of structural types of hexahedron 2.
The body of bolt 1, comprise and the center of hexahedron 2 axially establish a 12 through holes 3 that the top of through hole 3 is one section internal thread 8, through hole 3 can also be semicircle orifice or square hole.
Helical thread portion proximal head at the body of bolt 1 radially has 1～3 displacement slot 6.Several displacement slots can be equidirectional; Or it is rightabout to misplace; Or the dislocation any direction.Groove width 0.5～5mm, groove depth is identical or different.
As shown in Figure 4: the body of bolt 1 connects workpiece thread plate 10, workpiece joining plate 11 successively, and screws hexahedron 2.
As shown in Figure 3: give lockmaking mandrel 4.Lock shaft is the solid shaft of both end thread 5, and its top is provided with the angle 7 of rising of splashing.The angle best angle that rises of splashing is 45 °.
Lock shaft 4 is screwed in the through holes 3, make screw thread 5,8 engagements after, the expanding angle 7 of rising of splashing screws on the screw thread of the other end and regulates nut 9, makes near the threaded bodies 1 the displacement slot 6 produce displacement, by tightening the effect of friction, makes its locking workpiece.
The loosening nut 9 of regulating gets final product release.
