Abstract
The invention discloses a stop washer. The stop washer comprises two annular gaskets, including a first gasket and a second gasket. Annularly arranged convex teeth are arranged on one surface of the first gasket. Grooves matched with the convex teeth are arranged on one surface of the second gasket. The convex teeth extend from the inner circle to the outer circle of the gasket. The length of the convex teeth is less than the width of the gasket. The other surfaces of the first gasket and the second gasket are provided with annularly arranged stripped slots respectively. The washer is formed by the mutual meshing and connecting of the convex teeth and the grooves of the first gasket and the second gasket. According to the technical scheme of the stop washer, safety and reliability of the installed member part can be guaranteed; bolt loosening caused by a large load vibration is prevented; the stop washer can be installed and disassembled easily; the stop washer keeps the same performance in a lubricating state, which is not influenced by the strength of the acting force, the stop washer does not loose under severe environment and is durable and capable of being reused.
Description
Technical field
The present invention relates to a kind of packing ring, relate in particular to a kind of bolt that can prevent and in bigger oscillating load and bad working environment, produce loosening lock washer, belong 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.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: proposed a kind of simple in structure, easy for installation, the lock washer that relaxation effect is good.
Technical solution of the present invention is achieved in that a kind of lock washer, comprises two annular shims, is respectively first pad, second pad, and 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 present invention compared with prior art has advantage:
Lock washer of the present invention 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.

Embodiment
Below in conjunction with accompanying drawing the present invention is described.
Accompanying drawing 1-4 is a kind of lock washer of the present invention, 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 present invention compared with prior art has advantage:
Lock washer of the present invention 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.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
