Abstract
The utility model relates to a kind of checknut device, belongs to technical field of mechanical design.The utility model adopts following technological scheme: a kind of checknut device, it is characterized in that, comprise fluting threaded collar, internal thread ring, taper pin, the outer side wall of described fluting threaded collar is provided with outside thread, described fluting threaded collar and described internal thread ring pass through scyewed joint, the end face of described fluting threaded collar has multiple circular cone pin-and-hole, and the circular cone pin-and-hole place of described fluting threaded collar is provided with radially through, not through vertically narrow groove.The utility model can compress degree to adjust by adjustment taper pin and circular cone pin-and-hole the size that the narrow groove of slotting threaded collar circular cone pin-and-hole place opens, and then control the size of the pretightening force between fluting threaded collar and internal thread ring screw pair, can effectively improve anti-loose ability; Fluting threaded collar end face circumferentially has multiple adjustable hook spanner hole, conveniently installs and removes threaded collar.
Description
Technical field
The utility model relates to a kind of checknut device, belongs to technical field of mechanical design.
Background technique
For being hit, for the screw connection of the operating mode impact such as vibration, anti-loose ability is the important indicator evaluating its performance.Frictional force between the junction plane of increase screw pair is one of effective measures improving locking thread ability.
For improving the frictional force connected between screw pair junction plane, improving locking thread ability, occurring a series of locking thread technology.Have riveting rush locking, machinery is locking, rub the locking thread technology such as locking.But all there is certain defect in prior art.It is very limited that locking using scope is rushed in riveting, and a lot of occasion cannot use; The locking subject matter of machinery is that its locking mode does not have pretightening force, and namely when bolt pine falls back on locking position, locking mode effect could occur; Rubbing lockingly has the measures such as spring washer, can increase screw pair pretightening force to a certain extent, but it is locking limited in one's ability, and is generally only applicable to the occasion that standard thread connects, for special screw thread or comparatively major thread connect and can not adapt to.
Model utility content
The purpose of this utility model is to provide a kind of checknut device, to overcome existing locking thread measure relaxing serializability and the limited problem of applicable situation.
For solving the problems of the technologies described above, overcome the defect that prior art exists, the utility model provides a kind of checknut device, the utility model adopts following technological scheme: a kind of checknut device, it is characterized in that, comprise fluting threaded collar, internal thread ring, taper pin, the outer side wall of described fluting threaded collar is provided with outside thread, described fluting threaded collar and described internal thread ring pass through scyewed joint, the end face of described fluting threaded collar has multiple circular cone pin-and-hole, the circular cone pin-and-hole place of described fluting threaded collar is provided with radially through, narrow groove not through vertically.
Furthermore, the end face of threaded collar of slotting has two circular cone pin-and-holes of relative centre symmetry.
Furthermore, the back-end radius of taper pin is greater than the outer end radius of circular cone pin-and-hole, after the circular cone pin-and-hole of taper pin press-in fluting threaded collar, narrow groove along circular cone pin-and-hole place after fluting threaded collar is subject to taper pin pressure outwards expands, increase the pretightening force between fluting threaded collar and internal thread ring screw pair, reach the object of self-locking anti-loosing.
Furthermore, taper pin is taper pin with internal thread, is convenient to dismounting.
Furthermore, fluting threaded collar end face circumferentially has multiple adjustable hook spanner hole, so that mounting or dismounting threaded collar.
Furthermore, the number in adjustable hook spanner hole is 4.
The beneficial effect that the utility model reaches: (1) compresses degree to adjust by adjusting described taper pin and circular cone pin-and-hole the size that the narrow groove of slotting threaded collar circular cone pin-and-hole place opens, control the size of the pretightening force of fluting threaded collar and internal thread interannular, can effectively improve anti-loose ability, and can be applicable to special screw thread or the special occasions compared with major thread, structural design is simple, easy to assembly, overall dimensions is less, coupling mechanism force is large, and do not damage screw thread, repeatedly also can not damage through mounting or dismounting, reusable; (2) threaded collar of slotting end face circumferentially has multiple adjustable hook spanner hole, conveniently installs and removes threaded collar.
Accompanying drawing explanation

Fig. 2 is the structural representation of plan view of the present utility model.
Fig. 3 is the structural representation of explosive view of the present utility model.
The implication marked in figure: 1-slots threaded collar, 2-internal thread ring, 3-taper pin with internal thread, 4-circular cone pin-and-hole, 5-adjustable hook spanner hole.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As depicted in figs. 1 and 2 be the structural representation of plan view of the present utility model and the structural representation of plan view respectively, the utility model provides a kind of checknut device, comprise fluting threaded collar 1, internal thread ring 2, taper pin with internal thread 3, fluting threaded collar 1 passes through scyewed joint with internal thread ring 2, fluting threaded collar 1 end face on relative centre symmetry have two circular cone pin-and-holes 4, fluting threaded collar 1 circular cone pin-and-hole place 4 be provided with radially through, not through vertically narrow groove.Adopt taper pin with internal thread 3, be convenient to dismounting.Fluting threaded collar 1 end face circumferentially has multiple adjustable hook spanner hole 5, so that mounting or dismounting threaded collar, the number in described adjustable hook spanner hole is 4.
As shown in Figure 3 be the structural representation of explosive view of the present utility model, the back-end radius of taper pin with internal thread 3 is greater than the outer end radius of described circular cone pin-and-hole 4, after taper pin with internal thread 3 is pressed into the circular cone pin-and-hole 4 of fluting threaded collar 1, narrow groove along circular cone pin-and-hole 4 place after fluting threaded collar 1 is subject to taper pin with internal thread 3 pressure outwards expands, increase the pretightening force between fluting threaded collar 1 and internal thread ring 2 screw pair, reach locking object.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and distortion, these improve and distortion also should be considered as protection domain of the present utility model.
