Abstract
The utility model relates to a check washer which comprises two annular pads, namely a first pad and a second pad, wherein annularly arranged convex teeth are arranged on one face of the first pad; grooves matched with the convex teeth are formed in one face of the second pad; the convex teeth extend from the inner circles of the pads to the outer circles of the pads; the lengths of the convex teeth are smaller than the widths of the pads; annular arranged strip-type slots are respectively formed in the other face of each of the first pad and the second pad; and the washer is implemented through the first pad and the second pad due to meshing of the convex teeth and the grooves. By the check washer, structural members to be assembled are safe and reliable; a phenomenon of bolt looseness caused by relatively-large-load vibration can be avoided; the check washer is easy to assemble and disassemble; in a lubricating state, the performance is constant; moreover, the influence caused by the acting force is avoided; under a severe environment, the check washer can not get loose; and the check washer is durable and can be repeatedly used.
Description
Technical field
The utility model relates to a kind of packing ring, relates in particular to a kind of bolt that can prevent and in bigger oscillating load and bad working environment, produces loosening lock washer, belongs to the fixed component technical field.
Background technique
Reliability for the bolt that guarantees to use in the engineering; Existing technology uses plain washer to increase the lifting surface area of fastening force; Use the elastic force of spring washer to prevent bolt looseness, however the packing ring of this structure under bad working environment and bigger oscillating load, the clamping force of bolt still can descend rapidly; Its stopping effect that prevents bolt looseness is unsatisfactory; Bolt looseness can cause machine, equipment work unreliable, can bring a series of potential safety hazard, if packing ring can not use repeatedly also and can cause the wasting of resources.
The model utility content
The utility model purpose is to provide a kind of simple in structure for the deficiency that overcomes existing technology, and is easy for installation, the lock washer that relaxation effect is good.
For achieving the above object, the technological scheme that the utility model adopts is: a kind of lock washer, comprise two annular shims, and be respectively first pad, second pad, said first pad one side is provided with the double wedge of arranging in the form of a ring; Said second pad one side is provided with the groove that matches with said double wedge; Said double wedge extends from the outside circular direction of the interior circle of pad, and the length of double wedge is less than the width of pad; Be respectively equipped with the bar-shaped trough of array in the form of a ring on the another side of said first pad and second pad; Said packing ring is connected realization through double wedge with being meshing with each other of groove with second pad through first pad.
Preferably, said double wedge is slope shape, and said groove is the sloping shape that matches with double wedge.
Preferably, said bar-shaped trough is slope shape.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
The lock washer of the utility model scheme can guarantee that the member of installing is safe and reliable; Prevent to vibrate the bolt looseness that causes because of big load; Installation and removal are easy; Its performance is constant under lubricating status, and does not receive the strong and weak influence of active force, under rugged environment, also can not become flexible; Have durability, reusable.
Description of drawings
Below in conjunction with accompanying drawing the utility model technological scheme is described further:
Accompanying drawing 1 is the three-dimensional structure diagram of a kind of lock washer of the utility model;
Accompanying drawing 2 is the stereochemical structure exploded view of a kind of lock washer of the utility model;
Accompanying drawing 3 is the first pad three-dimensional structure diagram of a kind of lock washer of the utility model;
Accompanying drawing 4 is the second pad three-dimensional structure diagram of a kind of lock washer of the utility model;
Wherein: 1, first pad; 2, second pad; 3, double wedge; 4, groove; 5, bar-shaped trough.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
Accompanying drawing 1-4 is the described a kind of lock washer of the utility model, comprises two annular shims, is respectively first pad, 1, the second pad 2, and said first pad, 1 one side is provided with the double wedge of arranging in the form of a ring 3; Said second pad, 2 one sides are provided with the groove 4 that matches with said double wedge 3; Said double wedge 3 extends from the outside circular direction of the interior circle of pad, and the length of double wedge 3 is less than the width of pad; Be respectively equipped with the bar-shaped trough 5 of array in the form of a ring on the another side of said first pad 1 and second pad 2; Said packing ring is connected realization through double wedge 3 with being meshing with each other of groove 4 with second pad 2 through first pad 1; Said double wedge 3 is slope shape, and said groove 4 is the sloping shape that matches with double wedge 3; Said bar-shaped trough 6 also is slope shape.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
The lock washer of the utility model scheme can guarantee that the member of installing is safe and reliable; Prevent to vibrate the bolt looseness that causes because of big load; Installation and removal are easy; Its performance is constant under lubricating status, and does not receive the strong and weak influence of active force, under rugged environment, also can not become flexible; Have durability, reusable.
Below only be the concrete exemplary applications of the utility model, the protection domain of the utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, or any to move mode dull and stereotyped described in the utility model, all drop within the utility model rights protection scope.
