Certain damage is caused to the fixed border of blackboard, influences aesthetics when installation, and when installation quality is poor, screw does not have
When inlayed completely into wall, it is easy on the move to cause human body certain injury.
2. when the damage of the dust stratification slot of blackboard is needed replacing or cleared up, disassembly is difficult when in use for existing blackboard
It spends larger, and biggish damage is caused to blackboard connecting plate, influence beautiful and use in the installation in later period.
Utility model content
It is mentioned above in the background art to solve the purpose of this utility model is to provide a kind of environment-friendly dustless type blackboard
Blackboard is generally directly fixed with metope by screw during installation, when being fixedly mounted, fixed border of the screw to blackboard
Certain damage is caused, aesthetics when installation is influenced, and when installation quality is poor, screw is not inlayed completely into wall
When, it is easy on the move to cause human body certain injury, when the dust stratification slot damage of blackboard is needed replacing or cleared up
When disassembly difficulty it is larger, and biggish damage is caused to blackboard connecting plate, influenced in the installation in later period it is beautiful and using and
Dust on blackboard is easy to drift the pollution for leading to air in air, obscure sight and the physiological health for influencing human body, deposits
The biggish safety and sanitation hidden danger the problem of.
To achieve the above object, the utility model provides the following technical solutions: a kind of environment-friendly dustless type blackboard, including blackboard
Fixed border, fixation hole protective cover and dust stratification slot, the surface of the blackboard fixed border are provided with fixation hole, and the fixation hole is anti-
By card slot card and the inside for being fixedly mounted on fixation hole, the junction of the blackboard fixed border between any two is provided with protecting cover
Blackboard connects fixture block, and the inside of the blackboard fixed border is fixedly installed blackboard main body by inlaying, the blackboard fixed edge
The bottom end of frame is provided with dust stratification slot connecting plate, and the surface of the dust stratification slot connecting plate is provided with dust stratification slot connecting plate connecting groove,
The end of the dust stratification slot is provided with dust stratification slot connection tongue, and the dust stratification slot is mounted on the surface of dust stratification slot connecting plate, described
The dust stratification slot connecting plate connecting groove that the dust stratification slot connection tongue of dust stratification slot end setting connect plate surface setting with dust stratification slot is logical
Cross card slot card be fixedly connected.
Preferably, the blackboard fixed border is stainless steel component.
Preferably, the fixation hole protective cover has elastic property.
Preferably, the dust stratification slot connecting plate with a thickness of four centimetres.
Preferably, the dust stratification slot is U-shaped structure.
Preferably, the fixation hole protective cover is the composite construction of rotary table and annulus.
Compared with prior art, the utility model has the beneficial effects that
(1) fixation hole designed in the utility model can be directly attached by fixation hole in connection, it is therefore prevented that
The frame that blackboard is damaged in connection ensure that its aesthetics, while the fixation hole protective cover designed can be installed it
Fixation hole is protected afterwards, so that exposed screw will not scratch user of service.
(2) the dust stratification slot designed in the utility model can directly be carried out when replace and either being cleared up
Disassembly, uses very simple and convenient, and is preferably minimized to the damage of connecting plate, will not cause the use in later period.
