Seal boss around memory construction opening, the seal boss extend in memory construction opening along the surface of rear cover ontology,
And support level in rectangular configuration is formed, and there is the outer cover clamping groove to lower recess in a long side of the seal boss, it should
The groove bottom of outer cover clamping groove is higher than the inner surface of rear cover ontology；It is recessed on the inner edge of two long sides of support level and is formed
There is the first bayonet of face, is provided with bolt connecting hole, the inner edge of another short side on a short side of the support level
On be formed with a locating notch and two the second bayonets, the depth of the locating notch is less than the second bayonet, and width is greater than
Second bayonet, two second bayonets are oppositely arranged on the two sides of locating notch.
Using the above structure, by the design of seal boss and support level, memory bar outer cover lid can be made to close in memory
When on construction opening, there is better sealing, the impurity such as dust are not easily accessible, and are played preferably protection to memory bar and are made
With；Meanwhile by the design of outer cover clamping groove, it is easily inserted memory bar outer cover, is easily installed and dismantles, also, by fixed
Memory bar outer cover can be accurately positioned in position notch, can connect and fix memory bar outer cover by the first bayonet and the second bayonet.
As preferred: the rear cover ontology is equipped with arc recessing groove in the outer fringe position of corresponding bolt connecting hole.Use with
Upper structure unloads memory bar outer cover convenient for scratching to open.
As preferred: using chamfered transition between the arc recessing groove and the outer surface of rear cover ontology.Using the above knot
Structure, convenient for opening memory bar outer cover.
As preferred: the width that the support level corresponds to a long side of outer cover clamping groove location is less than another long side
Width.Using the above structure, convenient for the installation and removal of memory bar outer cover.
As preferred: being provided at least two Main board bolts attachment bases, the master on the inner surface of the rear cover ontology
Crab bolt attachment base is distributed in around memory construction opening.Using the above structure, it is securely fixed mainboard position, prevents memory bar
It gets loose.
As preferred: being provided at least one mainboard support base, the mainboard branch on the inner surface of the rear cover ontology
Support seats against nearly memory construction opening.Using the above structure, it provides for mainboard and reliably supports.
Compared with prior art, the utility model has the beneficial effects that
Using notebook host rear cover provided by the utility model, structure novel, it is easy to accomplish, it can effectively improve
The leakproofness of rear cover with memory construction opening makes memory bar be not easy dust stratification, while can reliably support memory bar outer cover,
Convenient for the installation and removal of memory bar outer cover.
Detailed description of the invention
