Abstract
A connection seat comprises a connection seat body (1) and fixed holes (2) arranged on the circumferential face of an outer circle of the connection seat body (1). The fixed holes (2) are threaded holes, and the axes of the fixed holes (2) are perpendicular to the axis of the connection seat body (1). The fixed holes (2) are circular truncated cone holes. Compared with the prior art, the fixed holes are the circular truncated cone holes, and bolts with circular truncated cone screws are matched with the circular truncated cone holes. When the bolts are screwed with the fixed holes, under the action of the circular truncated cone holes and the circular truncated cone screws, the screws are screwed to be tighter. In the actual practice, tightness of connection is better, and the phenomenon of leakage is not easy to occur. Consequently, the connection seat has the advantages of being good in tightness after assembly, and not easy to leak.
Description
Technical field
The utility model belongs to the valve arrangement field, particularly relates to a kind of connecting base for valve body.
Background technique
At present, the connecting base that prior art is used for valve body is provided with fixed hole, fixed hole is tapped hole, the axis of fixed hole is vertical with the axis of connecting base, but because the fixed hole aperture is single aperture, then after assembling, after bolt screws in fixed hole, the situation of leaking easily appears in fixed hole, and sealing is relatively poor.
The model utility content
Sealing was better after the utility model provided a kind of assembling for above problem, antileakaging connecting base.
The utility model overcomes the above problems used technological scheme: a kind of connecting base with following structure is provided, it comprises connecting base body and the fixed hole that is arranged on the connecting base body outer peripheral surface, described fixed hole is tapped hole, the axis of fixed hole is vertical with the axis of connecting base body, and described fixed hole is the frustoconic shape hole.
After adopting above structure, compared with prior art, the utility model is because fixed hole is the frustoconic shape hole, then matching with the frustoconic shape hole also is the bolt with frustoconic shape screw rod, and after bolt and fixed hole screw, under the effect of frustoconic shape hole and frustoconic shape screw rod, it is tightr after screw rod screws, so that when reality is used, the better tightness of connection is not prone to the situation of leakage.Therefore sealing is better after the utlity model has assembling, antileakaging characteristics.
Description of drawings
Fig. 1 is the structural representation of the utility model connecting base.
As shown in the figure: 1, connecting base body, 2, fixed hole.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
A kind of connecting base as shown in Figure 1, it comprises connecting base body 1 and the fixed hole 2 that is arranged on connecting base body 1 outer peripheral surface, described fixed hole 2 is tapped hole, the axis of fixed hole 2 is vertical with the axis of connecting base body 1, general fixed hole 2 is through hole, described fixed hole 2 is the frustoconic shape hole, and certainly the aperture of nearly connecting base body 1 outer peripheral surface one end of fixed hole 2 is greater than fixed hole 2 the other end apertures, otherwise to screw rear sealing relatively poor with bolt.
Installation method is identical with the method for prior art.
Above embodiment only is preferred embodiment of the present utility model, and the utility model is not limited only to above embodiment and has also allowed other structural change, allly changes in the utility model rights to independence claimed range, all belongs to the utility model protection domain.
Claims (1)
1. connecting base, it comprises connecting base body (1) and is arranged on fixed hole (2) on connecting base body (1) outer peripheral surface, described fixed hole (2) is tapped hole, the axis of fixed hole (2) is vertical with the axis of connecting base body (1), it is characterized in that: described fixed hole (2) is the frustoconic shape hole.
