Description
Technical field
The invention belongs to electrical appliance, and in particular to a kind of power outlet back box.
Background technology
Power outlet is essential in house construction, and general civil socket uses concealed bottom box mostly in order to attractive in appearance, i.e.,
Dug a hole in metope, power outlet back box is fixed in hole, then socket panel is fixed in power outlet back box with bolt.It is existing
Having in technology has a kind of back box, vertical columns in back box side wall, opens up longitudinal hole on column, nut is embedded in into the longitudinal hole
It is interior；Bolt is screwed into nut during use, but this back box nut is inlayed cumbersome, and bolts and nuts position is not easy pair
Together, assembling is difficult.
From the point of view of on surface, the power outlet of architectural fixation on the wall is very simple, and the thinking of inertia is also to use spiral shell
The structure of bolt nut will connect between socket panel and back box, because the connected mode of screw bolt and nut simply is also easy to think very
Arrive.But to be based on a kind of Practical Consideration in putting into practice：Power outlet for building, its diameter of bolt all very littles are generally 2 millimeters or 3
Millimeter, so small diameter, when twisting bolt, somewhat one is firmly excessive, and screw thread will be destroyed, the nut being fixed in back box
It cannot use again.Thus, the nut in back box can easily be changed and just seem extremely important.But back box space is small, prior art
In back box structure, replacing nut can not be realized.
In order to solve this problem, there is another power outlet back box again in the prior art, using metal with holes
Thin slice replaces nut, and sheet metal is fixed in back box side wall, but sheet metal is easily deformed when being screwed into bolt, once
Deformation cannot again be screwed into or back-out bolt.It is unpractical that sheet metal is changed under this structure.Once socket panel damages
Bad to need to change, after bolt is back-outed, sheet metal, which is easily damaged, causes whole power outlet back box to reuse,
Power outlet back box can only be changed.And changing power outlet back box will take out old back box from hole, metope will necessarily be damaged,
It is attractive in appearance to influence metope, increases construction cost.And if be changed without back box, socket panel cannot be fixed in back box, caused very
Power outlet back box is exposed in more places, and electric wire is also exposed, brings potential safety hazard.
Building power outlet is a small articles, and corresponding back box is also a small articles, and market price is very low, is examined based on cost
Consider and be also impossible to solve nut and back box replacement problem using the technology of complexity, it is necessary to be simple and practical.And in the prior art
Never rational solution, many troubles are also brought to construction business and user.
The content of the invention
The technical problem to be solved in the present invention is：Overcome the deficiencies in the prior art, there is provided a kind of power outlet back box, the electricity
Supply socket back box can be convenient for changing nut, power outlet back box is recycled.
The technical solution adopted for the present invention to solve the technical problems is：Invent a kind of power outlet back box, including back box
Side wall and bottom surface, it is characterised in that：Column is respectively fixed with the inside of two opposing sidewalls of back box, it is logical that longitudinal direction is opened up in column
Hole, the bottom of longitudinal hole open up nut lock chamber, and described longitudinal hole is connected with nut lock chamber；In nut on column
Openning is opened up in the side wall of lock chamber position.
Preferably, long hole slot is opened up from top in column side wall, described long hole slot is connected with openning.
Preferably, nut fixes cavity wall and is provided with some ribs or salient point.
Preferably, nut lock chamber interior shape is identical with nut.
Compared with prior art, the beneficial effects of the invention are as follows：
The 1st, nut lock chamber is set in column, and openning is opened up in the side wall of column top nut lock chamber position, when old
When nut damages, old nut can be taken out to the nut more renewed from openning, without changing whole power outlet back box, ensured
The reusing of power outlet back box, avoids metope from being destroyed.
2nd, the nut of required replacing is standard component, and user is easy to commercially change.
3rd, longitudinal hole outer wall opens up the long hole slot being connected with nut lock chamber openning on column, convenience finger or
Old nut is stirred out chamber, simple possible by thin rod.
The 4th, rib or salient point are set in nut lock chamber, frictional force can be strengthened, ensures that nut is difficult for drop-off.
5th, nut lock chamber interior shape is identical with nut, generally hex nut, is just blocked after nut is embedded in, and prevents
Nut follows bolt to rotate when only tightening bolt, increases reliability.
6th, column top opens up horn-like pilot hole, ensures that installation personnel in the case where can't see longitudinal hole, also can
Bolt is readily directed at longitudinal hole so as to be connected with nut.

Embodiment
Embodiment below in conjunction with the accompanying drawings, the present invention is described further：
As shown in figure 1, a kind of power outlet back box, the inner side of two opposing sidewalls 2 of back box is respectively equipped with column 1.Such as Fig. 2,3,5
Shown, the upper surface of column 1 is less than the upper surface of back box side wall 2, while the tip edge of column 1 is arranged to inclined-plane, reduces column and connects
Contacting surface, avoid column from hindering the placement of socket panel, also easily installed even if the big socket panel of junction board.Opened up in column 1
Longitudinal hole 3 corresponding with socket bolt position, longitudinal hole 3 extend through the bottom of column 1 always, and the top of longitudinal hole 3 is set
There is horn-like pilot hole 4, pilot hole 4 can guide bolt to move towards, and facilitate bolt alignment nut to be screwed into.Open the bottom of longitudinal hole 3
If nut lock chamber 5, longitudinal hole 3 is connected with nut lock chamber 5；Opened on column 1 in the side wall of the position of nut lock chamber 5
If openning 6, the size of openning 6 is supporting with nut, facilitates nut to be placed and taken out.If the inwall of nut lock chamber 5 is provided with simultaneously
Dry rib 7, can strengthen frictional force, prevent nut from dropping, and rib 7 can also be replaced with salient point；The interior shape of nut lock chamber 5 with
Nut is identical, generally hexagonal configuration, is just blocked after nut is embedded in, and nut follows bolt to rotate when preventing from tightening bolt.
Long hole slot 8 is opened up from top in the side wall of column 1, long hole slot 8 is connected with openning 6, facilitates finger or thin rod to transfer to nut.
The present invention is as follows using process：
As shown in figure 4, during mounting receptacle panel, by the first inserted num lock chamber 5 of nut 10, socket panel 9 is placed, by bolt
11 are screwed into nut 10 by longitudinal hole 3, complete to fix, and horn-like pilot hole 4 can ensure that bolt 11 is directed at longitudinal hole 3
So as to be connected with nut 10.
When the damage of nut 10 needs to change, it need to only be stretched into finger or thin rod from longitudinal hole 3, utilize long hole slot 8
Space, nut 10 is transferred to from openning 6, the nut more renewed, from without changing whole power outlet back box, made
Obtain power outlet back box to be reused, avoid metope and be damaged.Required nut is standard component, and user is easy to purchase
Buy, it is convenient to replace.It is worth noting that：Long hole slot 8 is nonessential, can also take out nut even if not long hole slot.
The above described is only a preferred embodiment of the present invention, being not the limitation for making other forms to the present invention, appoint
What those skilled in the art changed or be modified as possibly also with the technology contents of the disclosure above equivalent variations etc.
Imitate embodiment.But it is every without departing from technical solution of the present invention content, the technical spirit according to the present invention is to above example institute
Any simple modification, equivalent variations and the remodeling made, still fall within the protection domain of technical solution of the present invention.
