Abstract
A spring washer comprising a single turn washer body (1); the anti-loosening convex teeth (2) are uniformly arranged on the inner side of the gasket body (1) and form an included angle of 30-60 degrees with the bottom plane of the gasket body (1); the head end (1.1) and the tail end (1.2) of the gasket body (1) are meshed. The utility model discloses a head end and the tail end of packing ring body mesh mutually, and the head end makes the tail end compress to the center of packing ring body under the fastening force effect of nut, and the central diameter of packing ring body diminishes, makes its clamping double-screw bolt that can tightly to increase the fastening force of packing ring body on the double-screw bolt, reach and prevent spring washer pivoted purpose. The utility model discloses an inboard locking dogtooth of packing ring body produces to warp and wedges between the screw thread on the double-screw bolt and fixes it on the double-screw bolt under the pressure of nut, makes the locking effect of spring washer and nut can strengthen.
Description
Technical Field
The utility model relates to a spring washer belongs to fastener technical field.
Background
In the prior art, spring washers and helical-tooth nuts mostly adopt a plane of the washer or a tooth form of a protrusion arranged on the nut, and looseness is prevented by meshing a connected surface through the tooth form. Under the pressure of the nut and the washer, the tooth shapes on the nut and the washer are easy to deform due to the pressure, so that the tooth-shaped occlusion force is reduced, under the impact or vibration, the nut can be loosened due to the reduction of the occlusion force, and the nut can be finally loosened and loses efficacy along with the increase of the vibration or impact frequency.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problems that the tooth shapes on the nut and the washer are easy to deform due to pressure, so that the tooth-shaped occlusion force is reduced, the nut can be loosened due to the reduction of the occlusion force under the impact or vibration, and the nut can be finally loosened and loses efficacy along with the increase of the vibration or impact times.
In order to solve the technical problem, the utility model adopts the following technical scheme:
a spring washer includes a single-turn washer body; the inner side of the gasket body is uniformly provided with anti-loosening convex teeth which form an included angle of 30-60 degrees with the bottom plane of the gasket body; the head end and the tail end of the gasket body are engaged.
Adopt above-mentioned technical scheme's beneficial effect:
1. the utility model discloses a head end and the tail end of packing ring body mesh mutually, and the head end makes the tail end compress to the center of packing ring body under the fastening force effect of nut, and the central diameter of packing ring body diminishes, makes its clamping double-screw bolt that can tightly to increase the fastening force of packing ring body on the double-screw bolt, reach and prevent spring washer pivoted purpose.
2. The utility model discloses an inboard locking dogtooth of packing ring body produces to warp and wedges between the screw thread on the double-screw bolt and fixes it on the double-screw bolt under the pressure of nut, makes the locking effect of spring washer and nut can strengthen.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention;
FIG. 2 is a schematic structural diagram of a second embodiment of the present invention;
in the figure: 1-washer body, 1.1-head end, 1.2-tail end, 2-anti-loose convex tooth.
Detailed Description
The invention is described in further detail below with reference to the accompanying drawings:
example one
As shown in fig. 1, a spring washer includes a single-turn washer body 1; three anti-loosening convex teeth 2 are uniformly arranged on the inner side of the gasket body 1 and form an included angle of 40 degrees with the bottom plane of the gasket body 1; the head end 1.1 and the tail end 1.2 of the gasket body 1 are both conical inclined surfaces, and the two inclined surfaces are meshed; wherein the tapered inclined plane of the head end 1.1 is gradually narrowed from the upper plane to the lower plane of the gasket body 1, and the tapered inclined plane of the tail end 1.2 is gradually narrowed from the lower plane to the upper plane of the gasket body 1; under the effect of the fastening force of the nut, the head end 1.1 enables the tail end 1.2 to be compressed towards the center of the gasket body 1, the center diameter of the gasket body 1 is reduced, and the gasket body can tightly clamp the stud, so that the fastening force of the gasket body 1 on the stud is increased, and the purpose of preventing the spring gasket from rotating is achieved.
Example two
As shown in fig. 2, a spring washer includes a single-turn washer body 1; six anti-loosening convex teeth 2 are uniformly arranged on the inner side of the gasket body 1 and form an included angle of 50 degrees with the bottom plane of the gasket body 1; the head end 1.1 and the tail end 1.2 of the gasket body 1 are respectively provided with a groove, and the two grooves are meshed with each other; under the effect of the fastening force of the nut, the head end 1.1 enables the tail end 1.2 to be compressed towards the center of the gasket body 1, the center diameter of the gasket body 1 is reduced, and the gasket body can tightly clamp the stud, so that the fastening force of the gasket body 1 on the stud is increased, and the purpose of preventing the spring gasket from rotating is achieved.
In the use, the nut is compressing tightly the utility model discloses a during the packing ring body 1, 1 inboard locking dogtooth 2 of packing ring body produce to warp and wedge between the screw thread on the double-screw bolt and fix it on the double-screw bolt under the pressure of nut, make the locking effect of spring washer and nut can strengthen.
The utility model discloses a packing ring body 1's one end withstands the flank of tooth of skewed tooth nut to can reach the not hard up purpose of preventing the nut.
The number of the anti-loose convex teeth 2 is 3, 6, 9 or 12.
The locking convex teeth 2 and the bottom plane of the washer body 1 form an included angle of 35 degrees.
The anti-loosening convex teeth 2 and the bottom plane of the gasket body 1 form an included angle of 45 degrees.
The anti-loosening convex teeth 2 and the bottom plane of the gasket body 1 form an included angle of 55 degrees.
