Dough sheet body.
It addition, the height of groove is 0.4mm, a length of 0.5mm to 0.6mm, in order to maintainer
More convenient efficiently by blade or sheet metal insertion groove, and the performance of screening cover will not be caused shadow
Ring.
It addition, screening cover body sets reeded base angle more than one.So so that maintainer exists
During dismounting screening cover, it is possible to carry out levering up force from multiple angles of screening cover body, in order to will shielding
Lid body is whole to be pulled down, and further reduces screening cover probability of deformation when dismounting.
It addition, screening cover body has main leaf body and the multiple side pieces extended out by main leaf body；
If in reeded base angle, comprise the first the longest side pieces of length in screening cover body and this first side
The base angle that the second side pieces that dough sheet body is adjacent is constituted.
It addition, mask frame is provided with installing hole, screening cover is provided with the projection corresponding with installing hole, with
It is easy to screening cover closely cooperate with mask frame.

Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing pair
Each embodiment of the present utility model is explained in detail.But, those of ordinary skill in the art can
To understand, in each embodiment of this utility model, in order to make reader be more fully understood that, the application proposes
Many ins and outs.But, even if there is no these ins and outs and kind based on following embodiment
Plant and change and modifications, it is also possible to realize the application each claim technical scheme required for protection.
First embodiment of the present utility model relates to a kind of screening cover, as shown in Figure 1.Present embodiment
In screening cover comprise: screening cover body 1, at least one base angle in screening cover body 1 is provided with groove 11,
This groove 11 is used for levering up screening cover body 11.Wherein, screening cover body 1 have main leaf body 12 and
The multiple side pieces 13 extended out by main leaf body 12
Specifically, adding groove 11 on screening cover body 1, groove 11 can play dismounting and guide
Effect so that maintainer is when repair demolition screening cover, it is possible to by blade or sheet metal being inserted
Enter in groove, the mode that screening cover is levered up, so that screening cover is unlikely to deform when dismounting, facilitate
The disassembling section of maintainer, and improve the recycling rate of waterused of screening cover.Wherein, the height of groove is
0.4mm, a length of 0.5mm to 0.6mm, in order to maintainer more convenient efficiently by blade or
Person's sheet metal inserts groove, and will not impact the performance of screening cover.
And in the present embodiment, the base angle at groove 11 place, the longest for length in screening cover body 1
The first side pieces adjacent with this first side pieces second side pieces constitute base angle.Due to screen
Cover lid body 1 and be likely to an object in irregular shape, therefore select in screening cover body 1 length
The base angle that the second side pieces that the first long side pieces is adjacent with this first side pieces is constituted is as recessed
The base angle at groove 11 place, the base angle that i.e. choice structure more consolidates as the base angle at groove 11 place, from
And reduce screening cover body 11 possibility of deformation when dismounting as far as possible.Further, this base angle is selected to make
Base angle for groove 11 place so that maintainer, when levering up screening cover, operates the most laborsaving.Certainly,
When practical operation, being levered up by screening cover 11 for being further easy to maintainer, the second side pieces is also
Can be in the side sheet adjacent with the first side pieces, the side pieces that length is the longest.So, groove 11
Only illustrate with this and be limited in the base angle at place, do not do any restriction at this.Certainly, when practical operation,
Identifier can be provided with on main leaf body 12, as in figure 2 it is shown, identifier 121 is an arrow, in order to
Base angle set by indicia grooves 11, in order to maintainer can quickly find groove 11, saves
Maintenance time.So, in present embodiment, the concrete form to identifier 121 does not does any restriction,
Identifier 121 can also be triangle, rectangle etc..
It is noted that in present embodiment, screening cover body 11 is provided with the base angle of groove 11 and is more than
One so that maintainer is when dismantling screening cover, it is possible to carry out from multiple angles of screening cover body 11
Lever up force, in order to pull down whole for screening cover body 11, further reduce screening cover in dismounting
Time deformation probability.
Further, in the present embodiment, when arranging groove 11, it is provided with in the base angle of groove 11 and comprises
The second side sheet that the first side pieces that in screening cover body, length is the longest is adjacent with this first side pieces
The base angle that body is constituted, thus reduce screening cover body 11 possibility of deformation when dismounting as far as possible, and
Make maintainer when levering up screening cover, operate the most laborsaving.
This utility model the second embodiment relates to a kind of shield assemblies, as it is shown on figure 3, comprise: screen
Cover frame 2 and such as the screening cover in the first embodiment.Screening cover be located in mask frame 2；Screening cover
Removably connect with mask frame 2.Wherein, mask frame 2 is provided with installing hole 21, screening cover be provided with
The projection 14 that installing hole is corresponding, when screening cover be located in mask frame 2, installing hole 21 is with protruding
14 are mutually clamped.
It will be understood by those skilled in the art that the respective embodiments described above be realize of the present utility model
Specific embodiment, and in actual applications, can to it, various changes can be made in the form and details, and
Without departing from spirit and scope of the present utility model.
