Abstract
The invention discloses an SMA damping connector. The SMA damping connector comprises a screw barrel, a first gasket, a second gasket, a rubber ring, a clamp ring and a shell, the screw barrel is connected with the shell through the clamp ring, the screw barrel and shell respectively and firmly match with the first gasket and second gasket, and the rubber ring is located between the first gasket and the second gasket. The SMA damping connector uses the surfaces of two gaskets to extrude the rubber ring, and the influence to the axial size due to clamp ring connection is avoided.
Description
Technical field
The present invention relates to a kind of connector, particularly relate to a kind of SMA damping connection.
Background technique
Existing SMA damping connection forms damping by shell, the frictional force that directly produces between swivel nut both ends of the surface and seal ring.There is following problem in existing SMA damping connection: one, and damping strength is unstable.Two, because shell and swivel nut adopt snap ring to be connected, for ensureing to rotate, must have appropriate gap between part, the length dimension of the extruding rubber ring made controls difficulty, is not easy to processing.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of SMA damping connection, which employs the contact of two washer face extruding rubber rings, avoids the impact adopting snap ring to connect the axial dimension caused.
The present invention solves above-mentioned technical problem by following technical proposals: a kind of SMA damping connection, it is characterized in that, it comprises swivel nut, the first packing ring, the second packing ring, rubber ring, snap ring, shell, be connected by snap ring between swivel nut with shell, swivel nut and shell respectively with the first packing ring, the second packing ring close-fitting, rubber ring is between the first packing ring and the second packing ring.
Preferably, the material of described first packing ring and the material of the second packing ring are all teflon.
Positive progressive effect of the present invention is: present invention employs the contact of two washer face extruding rubber rings, avoid the impact adopting snap ring to connect the axial dimension caused.Two packing rings adopt teflon processing, add ductility, ensure that the stability of damping.Invention increases damping stability, ensure that the reliability of use.
Accompanying drawing explanation
Fig. 1 is the structural representation of SMA damping connection of the present invention.
Embodiment
Present pre-ferred embodiments is provided, to describe technological scheme of the present invention in detail below in conjunction with accompanying drawing.
As shown in Figure 1, SMA damping connection of the present invention comprises swivel nut 1, first packing ring 21, second packing ring 22, rubber ring 3, snap ring 4, shell 5, be connected by snap ring 4 between swivel nut 1 with shell 5, swivel nut 1 and shell 5 respectively with the first packing ring 21, second packing ring 22 close-fitting, rubber ring 3 is between the first packing ring 21 and the second packing ring 22.
SMA damping connection produces damping primarily of shell and swivel nut, ensure usage requirement, process is as follows: be connected by snap ring between swivel nut with shell, and ensure that connection is reliable and freely rotate, swivel nut and shell respectively with two packing ring close-fittings (material of two packing rings is teflon), by washer face extruding rubber ring produce stablize damping.Be connected by card 4 between swivel nut with shell, can shell and swivel nut can freely rotate like this.Swivel nut and shell respectively with the first packing ring, the second packing ring close-fitting, this avoid swivel nut, shell directly contact with rubber ring.Rubber ring is between the first packing ring and the second packing ring, and rubber ring, by two packing ring extrusion-deformations, produces resistance.
Present invention employs the contact of two washer face extruding rubber rings, avoid the impact adopting snap ring to connect the axial dimension caused.Two packing rings adopt teflon processing, add ductility, ensure that the stability of damping.Invention increases damping stability, ensure that the reliability of use.
Those skilled in the art can carry out various remodeling and change to the present invention.Therefore, present invention covers the various remodeling in the scope falling into appending claims and equivalent thereof and change.
Claims (2)
1. a SMA damping connection, it is characterized in that, it comprises swivel nut, the first packing ring, the second packing ring, rubber ring, snap ring, shell, be connected by snap ring between swivel nut with shell, swivel nut and shell respectively with the first packing ring, the second packing ring close-fitting, rubber ring is between the first packing ring and the second packing ring.
2. SMA damping connection as claimed in claim 1, it is characterized in that, the material of described first packing ring and the material of the second packing ring are all teflon.
