Abstract
A kind of structure for the antenna house plastic cement column cracking solving metal inlaying Nut column, metal nuts column edge is located in the post holes of antenna house plastic cement column, the post holes depth of antenna house plastic cement column is longer than the length of metal nuts column, by metal nuts column deeply to the bottom of the post holes of antenna house plastic cement column, make to reserve cavity between metal nuts column tail end face and the end face of antenna house plastic cement column.Do not changing original structure substantially, deepen the depth of antenna house plastic cement column post holes, metal nuts column is bumped into the bottom of antenna house plastic cement column post holes, make to reserve cavity between metal nuts column tail end face and the end face of antenna house plastic cement column, it eliminates stress to concentrate, since stress and temperature differences effect generate cracking phenomena after solution plastic cement column storage a period of time.
Description
Technical field
The utility model relates to antenna injection molding property field of structural design, particularly relate to a kind of solve metal inlaying Nut column
The structure of antenna house plastic cement column cracking.
Background technique
Internet rapidly develop to the communication technology propose requirements at the higher level, with antenna use context diversification, antenna can
By being continuously improved, exterior aerial be unable to do without antenna house, and antenna house is primarily used to the coat of protection inner antenna protection, therefore,
The antenna house of design cannot have any quality problems, and there are many assembly method of antenna house, we more select metal inlaying spiral shell at present
Female column, but stored there are antenna house plastic cement column and cracking phenomena, antenna house are had due to stress and temperature differences effect after a period of time
It after plastic cement column cracking, will be unable to be installed, need replacing antenna house, and the antenna after installing may be because of antenna house plastic cement
The cracking of column makes aerial radiation direction change, and can both generate serious consequence.
Utility model content
In order to solve the above technical problems, the antenna house plastic cement column that the utility model provides a kind of solution metal inlaying Nut column is opened
The structure split makes plastic cement column when antenna house metal inlaying Nut column not generate cracking phenomena, and structure after storage a period of time
Simply, at low cost.
To realize the above-mentioned technical purpose, used technical solution is: a kind of antenna house modeling solving metal inlaying Nut column
The structure of rubber column gel column cracking, metal nuts column edge are located in the post holes of antenna house plastic cement column, and the post holes depth of antenna house plastic cement column is long
Make metal nuts column tail by metal nuts column deeply to the bottom of the post holes of antenna house plastic cement column in the length of metal nuts column
Cavity is reserved between end surface and the end face of antenna house plastic cement column.
The utility model beneficial effect is: changing original structure substantially, is deepening antenna house plastic cement column post holes
Metal nuts column is bumped into the bottom of antenna house plastic cement column post holes by depth, moulds metal nuts column tail end face and antenna house
Cavity is reserved between the end face of rubber column gel column, stress is eliminated and concentrates, due to stress and temperature difference after solution plastic cement column storage a period of time
It influences to generate cracking phenomena.

Specific embodiment
It is right below in conjunction with attached drawing and case study on implementation in order to which the purposes, technical schemes and advantages of invention are more clearly understood
The present invention is further elaborated.It should be appreciated that particular embodiments described herein is used only for explaining the present invention, not
For limiting the present invention.
With reference to attached drawing 1,2, this structure there are cracking risk, injection moulded fittings itself is the disadvantage is that internal stress is bad, such as Fig. 1,2
The metal nuts column 1-2 edge is located in the post holes of antenna house plastic cement column 1-1, the tail end face and antenna of metal nuts column 1-2
What the injection molding endface position of cover plastic cement column 1-2 was generally flush with, it is very thin and be to hold that antenna house plastic cement column encases metal nuts column
Face is also that Jiao Chu is finally filled up in injection moulding process, it is easy to stress concentrated position is generated, so antenna house plastic cement column storage one
Since stress and temperature differences effect generate cracking phenomena after the section time.
A kind of structure for the antenna house plastic cement column cracking solving metal inlaying Nut column, the post holes of antenna house plastic cement column 1-1 are deep
Degree is longer than the length of metal nuts column 1-2, i.e. the post holes depth down of the antenna house plastic cement column 1-1 of injection molding, antenna house modeling
Rubber column gel column 1-1 apparent length is constant, using the metal nuts column of original length dimension, by metal nuts column 1-2 deeply to antenna house
The bottom of the post holes of plastic cement column 1-1 makes to reserve between metal nuts column 1-2 tail end face and the end face of antenna house plastic cement column 1-1
Cavity, the depth for reserving cavity is the 1/8-1/5 of metal nuts column 1-2 length.As in Fig. 3,4 antenna house plastic cement column 1-1 and
The injection molding post holes that metal nuts column 1-2 is matched is local deepened, and metal nuts column 1-2 gos deep into certain size inward, the reason is that
Deepen the encapsulated thickness of antenna house plastic cement column 1-1, generate stress concentration to eliminate, so solving antenna house plastic cement column stores one section
Since stress and temperature differences effect generate cracking phenomena after time.Attached drawing 5 is design invention antenna house metal inlaying nut rod structure
Explosive view.
Under limited conditions this simple structure can solve plastic cement column storage a period of time after due to stress and temperature
Degree difference influences to generate cracking phenomena.It is a kind of high reliablity, the structure design that structure is simple, at low cost.
The foregoing is merely preferable case study on implementation of the invention, are not intended to limit the invention, all in principle of the invention
With any modification made within method, equivalent modifications etc., should be included within the scope of the present invention.
