Abstract
The utility model discloses a kind of sealing blanking covers for fluid, are related to sealing device field, including：Plugging cover body and the retainer plate and sealing ring being sheathed on successively in plugging cover body；Sealing ring between plugging cover body and equipment for being sealed；Retainer plate between plugging cover body and equipment for being fixed.The sealing blanking cover of the utility model can be installed by the means of pressing with equipment, make prodigious raising there are one the installation effectiveness of sealing blanking cover, and there are one better locking or tamper effects because the design of hangnail can more make seal plug lid.
Description
Technical field
The utility model is related to sealing device field more particularly to a kind of sealing blanking covers for fluid.
Background technology
It is required for using sealing blanking cover in the equipment of all circulating liquids or gas, traditional sealing blanking cover, which is substantially all, to be adopted
Use plastics screw as sealing blanking cover.
A kind of seal plug structure as disclosed in Chinese invention patent CN 103672286A, including plug ontology, plug
There is ontology thread segment, thread segment to be telescopically disposed on plug ontology along the radial elastic of plug ontology；But plastic spiral
The blanking cover of silk type easy tos produce loosening, and is easy to cause security risk by layman's dismounting.
A kind of for another example fast sealing plug disclosed in China utility model CN 203880319U, including shell, work
Plug, end cap, sealing ring, magnet, hollow gasket, solid shims and three O-rings, shell one end are provided with internal thread, shell this
End is connect by screw thread with end cap, screw lock is used in combination, the shell other end is opened there are two inflating port and two installation threaded holes, living
It is sealed by O-ring between plug and shell, sealing ring is installed between end cap and piston, with hollow gasket between sealing ring and end cap
It separates, magnet is installed between sealing ring and piston, is separated with solid shims between magnet and sealing ring；But above-mentioned sealing loop knot
Structure complicated production cost is higher.
Utility model content
One, technical problems to be solved
The purpose of this utility model is to provide a kind of new seal plug for the above problem present in the prior art
Lid solves the problems, such as that the blanking cover of the prior art is easy to loosen or is easy to be disassembled in use.
Two, technical solution
In order to solve the above technical problems, the utility model provides a kind of sealing blanking cover for fluid includes：Plugging cover body,
And it is sheathed on retainer plate and sealing ring in plugging cover body successively；
Wherein, plugging cover body is equipped with the first card slot and the second card slot；Fixed trap is set on the first card slot；Seal snare
On the second card slot；
Wherein, retainer plate outer circle is equipped with sawtooth, and sawtooth can bend backwards to form hangnail.
Wherein, hangnail can be embedded in the required equipment blocked.
Wherein, retainer plate is sheet metal.
Wherein, plugging cover body is plastic injection piece.
Wherein, sealing ring is rubber ring.
Three, the beneficial effects of the utility model
Compared with prior art, the sealing blanking cover for fluid of the utility model has many advantages, such as follows：
(1) blanking cover of the utility model can be assembled directly by pressing, and improve the installation effectiveness of blanking cover；
(2) the utility model is designed by retainer plate, and making blanking cover after mounting has the function of locking and tamper.
Description of the drawings
Fig. 1 is the sealing blanking cover installation effect figure of the utility model；
Fig. 2 is the fixed ring figure of the utility model；
Fig. 3 is the hangnail partial enlarged view of the utility model Fig. 2.
In figure：1 is plugging cover body；2 be retainer plate；3 be sealing ring；4 be equipment；21 be sawtooth；22 be hangnail.
Specific implementation mode
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment cannot be used for limiting the scope of the utility model for illustrating the utility model.
The structure of the sealing blanking cover for fluid of the utility model embodiment includes as shown in Figure 1 to Figure 3：Plugging cover body
1 and the retainer plate 2 and sealing ring 3 that are sheathed on successively in plugging cover body 1；After sealing blanking cover is installed in equipment, sealing ring
3 between plugging cover body 1 and equipment 4 for being sealed, and retainer plate 2 between plugging cover body 1 and equipment 4 for consolidating
It is fixed.
Plugging cover body 1 is equipped with the first card slot and the second card slot；Retainer plate 2 is sheathed on the first card slot；Sealing ring 3 is arranged
In on the second card slot.
2 outer circle of retainer plate is equipped with sawtooth 21, and sawtooth 21 can form hangnail 22 with bending.
When sealing blanking cover is installed on equipment 4, the sawtooth 21 on retainer plate 2 bends backwards to be formed down under the action of receiving external force
Thorn 22, and hangnail 22 can be embedded in the required equipment blocked, and because of the relationship in 22 embedded equipment of hangnail, hangnail can not only
It enough clasps equipment and plays anti-loosing effect, moreover it is possible to keep sealing blanking cover just non-dismountable after mounting, can effectively prevent other people from disliking
Meaning is destroyed or dismantles in violation of rules and regulations and cause security risk.
Retainer plate 2 is sheet metal, and generally use punching machine is processed, and the production efficiency of retainer plate 2 improves a lot, and
Also reduce production cost.
Plugging cover body 1 is plastic injection piece, and retainer plate 2 can be pre-placed in a mold, make in 1 injection moulding process of plugging cover body
It can be molded with retainer plate 2 integrally.
3 generally use rubber ring of sealing ring makes.
The sealing blanking cover of the utility model is stamped plurality of advantages relative to existing plastic spiral silk plug：
The first, installation effectiveness is high, and the sealing blanking cover of the utility model only needs manually to be pressed with external force, makes it and set
It is standby to combine, it is not necessarily to excessive processing experience and technological difficulties；And the plastic spiral silk plug lid of the prior art is then comparatively multiple
It is miscellaneous, the equipment coordinated first will one of screw thread of multi-processing process, secondly plastic spiral silk plug cover on screw thread twist elasticity
It is directly related to the effect of sealing, needs veteran worker, otherwise unscrews and be easy to cause leakage, has tightened and has been easy to make
At the damage of plastic spiral silk plug lid；
The second, the reason of sealing blanking cover of the utility model is because of hangnail 22, it is just non-dismountable after being installed with equipment, it removes
Non- is destructive dismounting；And the plastics screw plug of the prior art is then easily removable, as long as being unscrewed；If there is not
If method molecule deliberately will do destruction, plastics screw need to only be unscrewed to several circles can cause very hidden complete hidden danger；And this
The seal plug of utility model can only be dismantled to deliberately destroy by destructiveness, and will necessarily after being dismantled by destructiveness
There is apparent violence damage trace, the discovery security risk that such technical staff can hold simultaneously excludes very in time.
Above are merely preferred embodiments of the utility model, it is noted that for the ordinary skill people of the art
Member for, without deviating from the technical principle of the utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the scope of protection of the utility model.
