Abstract
The utility model discloses a loose proof screwed connection assembly, comprising a loose proof bolt connection assembly and a loose proof screw connection assembly, the bottom face of the nut or the screw head is provided with at least two nib tooth form humps which are homogeneously arranged on the plane in radial shape. The upper face and the lower face of the spring shim are provided with at least two sawtooth projections which are homogeneously arranged on two planes in radial shape. The loose proof screwed connection assembly is a disposable screw fastener, which can be mounted according to normal method; the loose proof screwed connection assembly can not be loosened under the powerful vibrating operating condition, and is used for various burglar proof barrier nets.
Description
Technical field
The utility model relates to a kind of checknut link, belongs to the fastening means in the mechanical engineering element field.
Background technique
Existing checknut connection part generally adopts compression spring, its effect is that screw thread and the flank of thread on the screw rod on the nut are compressed mutually to increase friction, this is enough for the fastening effect under the common working condition, but in high strength, for a long time vibrate under the operating mode be threaded then not competent, for example, threaded fastener on railway ballast just is easy to loosening and comes off, and this will cause rail and railway roadbed is loosening and the danger of disengaging.In addition, on the guardrail of high-speed railway or highway, also need locking threaded fastener is installed, in case arbitrarily dismantle or the theft means of transportation.
Summary of the invention
The purpose of this utility model is: a kind of anti-loosening screwed assembly is provided, and it is a kind of disposable threaded fastener, only needs method routinely to install, and can not become flexible when using under powerful vibration.
The technical solution of the utility model is: the checknut connection part comprises bolt assembly of being made up of bolt, nut and compression spring and the screw assembly of being made up of screw, compression spring.Described anti-loosening screwed assembly comprises bolt, nut and the compression spring that cooperates with it; On the bottom surface of described nut, be provided with at least two sharp-tooth shaped projectioies, and become radial and be evenly arranged on the described bottom surface; On the upper and lower surface of spring pad, be provided with at least two sawtooth projections (5) at bullet, and become radial and be evenly arranged on this two plane; Constituting of described sawtooth projection: increase the ramp that constitutes sawtooth projection toward the clockwise direction gradually at compression spring, the end face of sawtooth projection is vertical with the plane of compression spring.
Another kind of anti-loosening screwed assembly comprises the screw and the compression spring of cooperation with it, is provided with two sharp-tooth shaped projectioies on the bottom surface of the screw head of screw, and becomes radial and be evenly arranged on this bottom surface; On the upper and lower surface of described compression spring, be provided with at least two sawtooth projections, and become radial and be evenly arranged on this two plane; Constituting of described sawtooth projection: increase the ramp that constitutes sawtooth projection toward the clockwise direction gradually at compression spring, the end face of sawtooth projection is vertical with the plane of compression spring (3)
Advantage of the present utility model is:
1, can not unclamp connection having under the operating mode of judder, for example be used for the joint of rail and the hurdle net of high-speed railway or highway etc.
2, can be used on the burglary-resisting installation.

Fig. 2 is the schematic perspective view of compression spring
Fig. 3 is the assembling schematic representation of backing-up screw assembly
Embodiment
As illustrated in fig. 1 and 2, subassembly of lock bolt comprises a bolt 1, nut 2 and spring pad 3, at least two sharp-tooth shaped projectioies 4 is set on the bottom surface of nut 2, and becomes on radial evenly distributed this bottom surface; On the upper and lower surface of compression spring 3, be equipped with at least two sawtooth projections 5, and become radial and be evenly arranged on this two sides; Described zigzag fashion is: go up toward the clockwise direction gradually at spring sheet 3 and increase, constitute the ramp of sawtooth projection 5, the end face of sawtooth projection 5 is vertical with the plane of compression spring 3, like this, can rotate smoothly during fastening nut 2 in the clockwise direction, and when nut 2 is subjected to reverse torsion, its sharp-tooth shaped projection 4 is stuck on the perpendicular end surface of sawtooth projection 5 of compression spring 3, nut 2 is lockable, therefore, can not become flexible between bolt 1 and the nut 2, form permanent chek bolt and connect.
As shown in Figure 3, the backing-up screw assembly comprises the screw 6 and the compression spring as hereinbefore 3 of Any shape screw head; Aforesaid working principle can be used on the backing-up screw connection part equally; Be provided with at least two sharp-tooth shaped projectioies 4 on the bottom surface of screw head 7, and become radial and be evenly arranged on this bottom surface, it is used with aforesaid compression spring 3 and forms permanent backing-up screw and be connected.
Claims (2)
