Problem.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: a kind of wing wallboard safeguards lid, described machine
Alar wall plate safeguards that lid includes end arc bonding pad and middle wide bonding pad, and end arc bonding pad and middle wide company
Meeting area is integral type structure, and the width of described end arc bonding pad is not equal to the width of the wide bonding pad in described centre, described
End arc bonding pad and middle wide bonding pad are equipped with bolt hole, bolt passing through bolt hole make end arc bonding pad and in
Between wide bonding pad be fixedly connected with wallboard.
Further, the width of end arc bonding pad is more than the width of the wide bonding pad in described centre.
Further, the bolt hole of described end arc bonding pad is double.
Further, the bolt hole of the wide bonding pad in described centre is single.
Further, the transitional region of the wide bonding pad in end arc bonding pad and described centre is round-corner transition.
Further, described wing wallboard safeguards that the material of lid is identical with the material of wing wallboard.
The utility model also provides a kind of wing lid wallboard, and described wing lid wallboard has and described wing wallboard dimension
The lid frame that retaining lid matches.
A kind of wing wallboard of the present utility model safeguards that lid adopts the back gauge design such as non-, and in the middle of lid, wide region is by little
Back gauge designs, and is overlapped with wallboard mouth frame using single bolt, and big back gauge design is pressed in lid end circular sliding slopes area, using double spiral shell
Bolt is overlapped with wallboard mouth frame, and compared with the design of little back gauge lid, wing wallboard of the present utility model safeguards that lid improves lid
Posting efficiency, improves structural strength, improves safety of structure；Compared with the design of big back gauge lid, wallboard opening size is less,
Construction weight is less, easy for installation, and maintainability is good.
Brief description
Accompanying drawing herein is merged in specification and constitutes the part of this specification, show meet of the present utility model
Embodiment, and be used for explaining principle of the present utility model together with specification.

Specific embodiment
For making purpose, technical scheme and advantage that the utility model is implemented clearer, below in conjunction with the utility model
Accompanying drawing in embodiment, is further described in more detail to the technical scheme in the utility model embodiment.In the accompanying drawings, ad initio
To the element that same or similar label represents same or similar element or has same or like function eventually.Described reality
Applying example is a part of embodiment of the utility model, rather than whole embodiments.Embodiment below with reference to Description of Drawings
It is exemplary type it is intended to be used for explaining the utility model, and it is not intended that to restriction of the present utility model.Based on this practicality
Embodiment in new, the every other reality that those of ordinary skill in the art are obtained under the premise of not making the work of creation type
Apply example, broadly fall into the scope of the utility model protection.Below in conjunction with the accompanying drawings embodiment of the present utility model is described in detail.
In description of the present utility model it is to be understood that term " " center ", " longitudinal ", " horizontal ", "front", "rear",
The orientation of instruction such as "left", "right", " vertical ", " level ", " top ", " bottom ", " interior ", " outward " or position relationship are based on accompanying drawing institute
The orientation showing or position relationship, are for only for ease of description the utility model and simplify description, rather than instruction or hint indication
Device or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to this practicality
The restriction of novel protected scope.
As Figure 1-3, wing wallboard of the present utility model safeguards that lid includes end arc bonding pad 11 and centre etc.
Wide bonding pad 12, and end arc bonding pad 11 and middle wide bonding pad 12 are integral type structure, end arc bonding pad 11
Width be not equal to the width of middle wide bonding pad 12, end arc bonding pad 11 and middle wide bonding pad 12 are equipped with spiral shell
Keyhole 13, bolt passing through bolt hole 13 makes end arc bonding pad 11 be fixedly connected with wallboard 2 with middle wide bonding pad 12.
Further, the bolt hole of end arc bonding pad 11 is double, and the bolt hole of middle wide bonding pad 12 is single,
And the width of end arc bonding pad 11 is more than the width of middle wide bonding pad 12.The why spiral shell of end arc bonding pad 11
Keyhole is that the bolt hole of double and middle wide bonding pad 12 is because the relatively middle wide company in end arc bonding pad 11 for single
Meet area 12 and bear larger power, the end that is, maintainability according to different parts and structural strength are determined is than middle part wide
On degree bigger thus bolt also just more.
Further, end arc bonding pad 11 and the transitional region of middle wide bonding pad 12 are round-corner transition, can be effective
Stress concentration in the transmittance process of elimination power.
Additionally, wing wallboard safeguard the material of lid 1 identical with the material of wing wallboard 2 it is ensured that intensity is enough.
In addition, safeguarding at the lid frame of the wing lid wallboard 2 that lid 1 matches with wing wallboard of the present utility model,
Should have and safeguard lid 1 identical shape with wing wallboard, that is, with end arc bonding pad 11 also for double bolt hole, centre etc.
Wide bonding pad 12 is single connecting hole.
A kind of wing wallboard of the present utility model safeguards that lid adopts the back gauge design such as non-, and in the middle of lid, wide region is by little
Back gauge designs, and is overlapped with wallboard mouth frame using single bolt, and big back gauge design is pressed in lid end circular sliding slopes area, using double spiral shell
Bolt is overlapped with wallboard mouth frame, and compared with the design of little back gauge lid, wing wallboard of the present utility model safeguards that lid improves lid
Posting efficiency, improves structural strength, improves safety of structure；Compared with the design of big back gauge lid, wallboard opening size is less,
Construction weight is less, easy for installation, and maintainability is good.
The above, optimum specific embodiment only of the present utility model, but protection domain of the present utility model is not
It is confined to this, any those familiar with the art, in the technical scope that the utility model discloses, can readily occur in
Change or replacement, all should cover within protection domain of the present utility model.Therefore, protection domain of the present utility model should be with
