Description
Technical field
The utility model relates to a kind of outdoor extension case, belongs to telecommunication apparatus manufacturing technology field.
Background technology
At present, the door-opening mode of the casing kind equipment that uses at field of telecommunications generally all is to split around door, install and during plant maintenance at equipment since factor bring inconvenience.Simultaneously because of having a structure slit between the top cover that splits around door and casing, with regard to waterproof and the dustproof problem of having brought box house.Especially telecommunications industry is used for outdoor extension case, because the interior installation of case all is communicating appliance equipment, waterproof and dustproof imprecision are the main causes that causes circuit question.
The utility model content
Technical problem to be solved in the utility model is: provide a kind of waterproof and dustproof effective open air extension case.
For solving the problems of the technologies described above the technical scheme that adopts be: a kind of outdoor extension case, the extension case body and the extension chamber door that is installed on this cube extension case body that comprise cube structure, the projection of described extension chamber door on cross section is inverted L-shaped, and it is hinged with the top margin of hanging case body rear wall by its roof that this inverted L-shaped is hung chamber door.
Further be, also comprise automatic open device, an end of automatic open device is connected with extension case body, and the other end is connected with the roof that inverted L-shaped is hung chamber door.
The optimal way of such scheme is, described automatic open device is pneumatic spring, and an end of pneumatic spring is connected with left side wall or the right side wall of hanging the case body, and the other end is connected with the roof of inverted L-shaped extension chamber door.。
The beneficial effects of the utility model are: be connected its place, structure slit with clamshell doors by the top cover that will hang the case body and connect, form the extension chamber door of inverted L-shaped structure, and being articulated and connected the original left and right sides of clamshell doors and extension case body, change inverted L-shaped extension chamber door into hinged with the top margin of hanging case body rear wall by its roof, so just, eliminate clamshell doors in the prior art and hung structure slit having between the case body top cover and the structure interval between clamshell doors and the extension case body two side, after inverted L-shaped extension chamber door is closed, just top side and clamshell doors one side seal that will hang the case body are tight, effectively solved the waterproof of outdoor extension case, dustproof problem has improved the waterproof of outdoor extension case, dust-proof effect.
Description of drawings
Fig. 1 is the opening schematic three dimensional views of a kind of outdoor extension case of the utility model;
Fig. 2 is the end view of a kind of outdoor extension case of the utility model.
Be labeled as among the figure: hang case body 1, top margin 11, hang chamber door 2, roof 21, automatic open device 3.
Embodiment
The effective open air extension case of a kind of waterproof and dustproof that the utility model provides as shown in Figure 1 and Figure 2.Described outdoor extension case comprises the extension case body 1 and the extension chamber door 2 that is installed on this cube structure extension case body 1 of cube structure, the projection of described extension chamber door 2 on cross section is inverted L-shaped, and it is hinged with the top margin (11) of hanging case body rear wall by its roof 21 that this inverted L-shaped is hung chamber door 2.Adopt the open air extension case of described structure, the top cover of hanging case body 1 is connected its place, structure slit to be connected with clamshell doors, form the extension chamber door 2 of inverted L-shaped structure, and being articulated and connected the original left and right sides of clamshell doors and extension case body 1, change inverted L-shaped extension chamber door 2 into hinged with the top margin 11 of hanging case body rear wall by its roof 21, so just, eliminate clamshell doors in the prior art and hung structure slit having between the case body top cover and the structure interval between clamshell doors and extension case body 1 two side, after inverted L-shaped extension chamber door 2 is closed, just top side and clamshell doors one side seal that will hang case body 1 are tight, effectively solved the waterproof of outdoor extension case, dustproof problem has improved the waterproof of outdoor extension case, dust-proof effect.
For being hung, inverted L-shaped can be fixed on the enable possition after chamber door 2 is opened, be convenient to the electrical equipment original paper in staff's installation, maintenance extension case body 1, in the above-mentioned execution mode, also comprise automatic open device 3, one end of automatic open device 3 is connected with extension case body 1, and the other end is connected with the roof 21 that inverted L-shaped is hung chamber door 1.After opening like this inverted L-shaped extension chamber door 2, inverted L-shaped is hung chamber door 2 just can remain on the unlatching shape automatically.Further, provide extra sealing load in order when closing, to hang chamber door 1 to inverted L-shaped, improve inverted L-shaped and hang the sealing effectiveness of chamber door 1, described automatic open device 3 is pneumatic spring, one end of pneumatic spring is connected with left side wall or the right side wall of hanging case body 1, and the other end is connected with the roof 21 that inverted L-shaped is hung chamber door 1.Like this, because gas spring self has several kilograms of precompressions, just can hang chamber door 1 to inverted L-shaped behind the door in the pass and apply certain precompression, thereby effectively improve the sealing effectiveness that inverted L-shaped is hung 1 pair of outdoor extension case of chamber door, further improve outdoor extension case waterproof and dustproof effective.
