The second is, be provided with hanging set, but this hanging set operated by rotary motion is in the bottom of passive light access device base, this set requires height space that passive light access device must vacate 10mm at least in short transverse for wall hanging, more than so the total height of passive light access device must be increased 10mm, this has just caused the increase of product material and the increase of assembly space, thereby increases the cost of product, and the wall hanging that is arranged on bottom makes installation process more difficult.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of cover device of passive light access device is provided, the cover device of this passive light access device can be arranged on hanging set on the bending edges of the left and right sides, make assembling be in a wide-open space, greatly reduce the difficulty of assembling, and can effectively reduce the total height of passive light access device, joint product material and assembling height space; In addition, this hanging set has adopted the design of slotted hole, can effectively reduce rigging error, and wall hanging is installed and seemed simple, and also simple in structure, practical.
In order to realize above-mentioned technical purpose, the utility model is realized by following technical scheme:
The cover device of a kind of passive light access device described in the utility model, comprise top cover, described top cover is frame type support body, the edge on the limit, the left and right sides of described top cover is provided with the bending edges of outside turnover for wall hanging, described side is provided with some rail shape louvres, described bending edges is provided with some installing holes for being connected with wall or wall hanging board, described installing hole is slotted hole, the utility model is because installing hole is set to slotted hole, can effectively reduce the alignment error of wall hanging, and assembling is in a complete open space, wall hanging is installed and seemed simple.
As the further improvement of above-mentioned technology, described louvre is that length dimension scope is the slotted hole that 18～20mm, width dimensions scope are 2～4mm, and the pitch of holes of two adjacent louvres is 4mm.
As the further improvement of above-mentioned technology, described installing hole is slotted hole, for length dimension scope is the slotted hole that 8～10mm, width dimensions scope are 4.5～6mm.Specifically, the installing hole of described each side of top cover is two, and the set installing hole in both sides is symmetrical arranged, and top cover correspondence is installed on wall or wall hanging board on after passing installing hole when wall hanging by hold-down screw.
Compared with prior art, the beneficial effects of the utility model are:
(1) the cover device of passive light access device described in the utility model can make passive light access device overall height dimension reduce at least 10mm, effectively saves assembly space, makes the selection of installation site of this equipment more some more, improves practicality;
(2) the cover device of passive light access device described in the utility model, due to by the installing hole on the bending edges of the left and right sides for slotted hole designs, can effectively reduce the alignment error of wall hanging, and assembling in a complete open space, wall hanging is installed and seemed simple, optimizing user is experienced;
(3) the cover device of passive light access device described in the utility model, simple in structure, easily installs, and lightweight, volume is little, and manufacturing process is simple, cheap.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail:
Fig. 1 is the cover device structural representation of passive light access device described in the utility model;
Fig. 2 is the cover device assembling schematic diagram of passive light access device described in the utility model.
Embodiment
As shown in Figure 1 and Figure 2, the cover device 10 of passive light access device described in the utility model, comprise top cover 1, described top cover 1 is frame type support body, the edge on the limit, the left and right sides 11 of described top cover 1 is provided with the bending edges 12 of outside turnover for wall hanging, the corner positions of described bending edges 12 is fillet 122, with anti-scratch.Described side 11 is provided with some rail shape louvres 111, and described bending edges 12 is provided with some installing holes 121 for being connected with wall or wall hanging board.The utility model, because installing hole is set to slotted hole, can effectively reduce the alignment error of wall hanging, wall hanging is installed and seemed more simple, and optimizing user is experienced; And installing hole designs in the left and right sides, make to install completely in an open space, operate simpler.
In the utility model, described louvre 111 for length dimension scope be the slotted hole that 18～20mm, width dimensions scope are 2～4mm, the pitch of holes of two adjacent louvres 111 is 4mm.
