Abstract
The utility model discloses a metal plane packing ring has the annular ring body structure of stamping forming, its characterized in that: the outer circumference of the annular ring body is provided with a cutting opening, the cutting opening cuts off and penetrates the inner ring and the outer ring of the annular ring body, and the inner ring of the annular ring body is provided with a point-shaped protrusion at a position close to the cutting opening; the inner ring or the outer ring of the annular ring body is provided with a circumferential notch at a position staggered from the cutting opening by 180 degrees, and the circumferential notch enables the radial width of the annular ring body to be narrowed and has elasticity. The utility model discloses simple structure can keep elastic contact and cooperate the use with the bolt excircle when fastening connection occasion is used, improves assembly efficiency.
Description
Technical Field
The utility model relates to a fastener product, concretely relates to metal plane packing ring.
Background
The metal plane washer is matched with a bolt or a screw, and is widely applied to fastening and connecting occasions. In the process of matching and using the metal plane washer and the bolt, because the size of an inner hole of the metal plane washer is larger than the size of an outer circle of the bolt, the situation that the metal plane washer is separated from the bolt easily occurs in the matching and using process, and the metal plane washer can fall to an installation dead angle and is not easy to take out after being separated from the bolt, so that the assembly efficiency can be seriously influenced.
Disclosure of Invention
The utility model aims to prior art not enough, the utility model aims at providing a simple structure can keep elastic contact and cooperate the use with the bolt excircle when fastening connection occasion is used, improves assembly efficiency's metal plane packing ring.
The utility model discloses a through following technical scheme implementation:
the metal plane gasket has a stamping annular ring body structure and is characterized in that: the outer circumference of the annular ring body is provided with a cutting opening, the inner ring and the outer ring of the annular ring body are cut and communicated through the cutting opening, and the inner ring of the annular ring body is provided with a point-shaped protrusion at a position close to the cutting opening.
The inner ring or the outer ring of the annular ring body is provided with a circumferential notch at a position staggered from the cutting opening by 180 degrees, and the circumferential notch enables the radial width of the annular ring body to be narrowed and has elasticity.
According to the metal plane washer adopting the technical scheme, the inner ring of the annular ring body is provided with the point-shaped protrusions, and the notches and the circumferential notches are arranged to enable the plane washer to have elasticity, so that when the plane washer and the bolt are used together in a fastening connection situation, an inner hole of the plane washer can be always in elastic contact with an outer circle of the bolt, the situation that the metal plane washer is separated from the bolt cannot occur, and the assembly efficiency is effectively improved.
Drawings
The utility model discloses there is following figure:
figure 1 is a schematic structural view of a first embodiment of the present invention,
figure 2 is a half-sectional view of figure 1,
fig. 3 is a schematic structural diagram of a second embodiment of the present invention.
Detailed Description
As shown in fig. 1 and 2, the metal plane gasket of the present invention has an annular ring body structure formed by stamping, the outer circumference of the annular ring body 1 is provided with a cut-off opening 3, the cut-off opening 3 cuts off the inner ring 12 and the outer ring 11 of the annular ring body to be through, the inner ring 12 of the annular ring body is provided with a dot-like protrusion 4 at a position close to the cut-off opening 3, the inner ring 12 of the annular ring body is provided with a circumferential notch 5 at a position staggered by 180 degrees from the cut-off opening 3, and the circumferential notch 5 narrows the radial width of the annular ring body 1 to have elasticity.
As shown in fig. 3, the metal plane gasket of the present invention has an annular ring structure formed by stamping, wherein a cut-off portion is provided on the outer circumference of the annular ring, the cut-off portion cuts off the inner ring and the outer ring of the annular ring to have a through-hole, the inner ring of the annular ring is provided with a dot protrusion at a position close to the cut-off portion, the outer ring of the annular ring is provided with a circumferential notch 6 at a position staggered by 180 degrees from the cut-off portion, and the circumferential notch 6 narrows the radial width of the annular ring and has elasticity.
Claims (2)
1. The metal plane gasket has a stamping annular ring body structure and is characterized in that: the outer circumference of the annular ring body is provided with a cutting opening, the inner ring and the outer ring of the annular ring body are cut and communicated through the cutting opening, and the inner ring of the annular ring body is provided with a point-shaped protrusion at a position close to the cutting opening.
2. The metal planar gasket as set forth in claim 1, wherein: the inner ring or the outer ring of the annular ring body is provided with a circumferential notch at a position staggered from the cutting opening by 180 degrees, and the circumferential notch enables the radial width of the annular ring body to be narrowed and has elasticity.
