At least one anti-rotation groove 3, can also use other similar structures the most here, if can realize spring base and seal casinghousing it
Between do not relatively rotate, spring base also can be along the axial side-to-side movement of seal casinghousing simultaneously.Anti-rotation groove quantity on spring base
Can be arranged as required to multiple, the most multiple anti-rotation grooves can be distributed along spring base body even circumferential, and described anti-rotation groove can be adopted
It is arc or square groove structure with cross section.Spring base is when assembling, and acting surface directly acts on stationary ring, and due to spring
The opening direction of seat front upper spring opening is in opposite direction with acting surface, can effectively prevent the fluid in mechanical seal from entering in spring eye,
Prevent fluid from the performance of spring being impacted, it is ensured that to act on the stability of active force on mechanical seal seal face.
Arranging coupling arrangement on spring base body 1, coupling arrangement here is for realizing between spring base and stationary ring
Connect, the most described coupling arrangement can use concrete attachment structure, it would however also be possible to employ certain connected mode, as by spring base with
Between stationary ring by bonding or welding by the way of be attached, the coupling arrangement in the present embodiment is for being arranged on spring base body 1
Stop pin 5 on acting surface, wherein stop pin 5 is fixedly connected on spring base body 1.During installation, spring base is by anti-rotation
Being connected between groove with seal casinghousing, spring base is by being connected between stop pin with stationary ring, thus realizes stationary ring, spring base and sealing
Do not relatively rotate between housing.
Preferably, described spring eye 2 is uniformly distributed along spring base body circumference；So can make to act on stationary ring by spring
On active force more uniform.
Embodiment two
As it is shown on figure 3, a kind of float type state type spring base, including ring spring seat body 1, described spring base body 1
One side end face is and the acting surface 4 of mechanical seal black box effect, contrary with this acting surface 4 on described spring base body 1
Opposite side end face is provided with multiple spring eye 2, and described spring base body 1 periphery is provided with at least one anti-rotation groove 3；Described
It is provided with outward extending support ring 6 on the acting surface of spring base body, described support ring 6 is provided with annular groove 7, described
Support ring 6 and spring base body 1 are monolithic construction.
During installation, the support ring 6 of spring base extend in stationary ring, between outer peripheral face and the inner peripheral surface of stationary ring of support ring 6
Cooperate, simultaneously sealing ring 14 is set in the groove 7 of support ring, make to have between stationary ring with spring base the most coaxial
Property, play the effect to spring base auxiliary positioning.
Equally, for realizing the connection between spring base and stationary ring, the present embodiment is equally arranged on spring base body
Coupling arrangement in embodiment one, the most just repeats no more.
This utility model further relates to a kind of mechanical seal structure, such as Fig. 4, including quiet assembly housing 8, stationary ring 9, moves assembly 10
With above-mentioned spring base 11, described stationary ring 9 and spring base 11 be arranged in quiet assembly housing 8, and the acting surface 4 of spring base 11 withstands on quiet
On the end face of ring 9 one end, being provided with spring 13 between spring base 11 and quiet assembly housing 8, described spring 13 is arranged on spring base 11
Spring eye 2 in, spring base 11 connects quiet assembly housing 8, specifically, quiet assembly housing 8 is fixedly installed and anti-rotation groove knot
The connecting key 12 that structure is corresponding, connecting key 12 stretches in anti-rotation groove 3, it is achieved the connection between spring base and quiet assembly housing；This
Time under the effect of connecting key and anti-rotation groove, limit relatively rotating between spring base and quiet assembly housing, and spring base can
Along quiet assembly housing axis direction left right horizontal movement；Being connected by coupling arrangement between spring base with stationary ring, spring base is with quiet
Connection between ring can realize by arranging the coupling arrangement such as stop pin on spring base, it is also possible to by spring base
Interference fit between support ring and stationary ring realizes, when using the mode arranging stop pin on spring base to be attached,
Stop pin one end is fixing with spring base to be connected, and the other end extend on stationary ring in the corresponding hole arranged, thus limits stationary ring
And relatively rotating between spring base.
When being provided with support ring 6 on spring base 11, the support ring 6 of described spring base 11 stretches in stationary ring 9, support ring 6
Outer peripheral face matches with stationary ring 9 inner peripheral surface, arranges sealing ring 14 in the annular groove 7 of support ring 6.By in support ring with quiet
Sealing ring is set between ring, not only acts as the coaxial positioning action between spring base with stationary ring, can realize simultaneously spring base with
Sealing between stationary ring inner peripheral surface.
